Title: Improvements in or relating to process of and means for discharging retort ovens
IPC: C10B33/02
Filed: 1931-01-12
Abstract: 358,385. Low temperature retorts. INTERTRUST COMPAGNIE GENERALE DE DISTILLATION ET COKEFACTION A BASSE TEMPERATURE ET MINIERE, SOC. ANON., 1, Poststrasse, Glaris, Switzerland.-(Assignees of International Holding de Distillation et Cokefaction a Basse Temperature et Miniere (Holcobami) ; 8, Rue de ]a Regence, Brussels.) Jan. 12, 1931, No. 1078. Convention date, Jan. 24, 1930. [Classes 51 (ii) and 55 (i).] Discharging.-Retorts for low temperature carbonization having movable bottoms are discharged by imparting two shocks to the charge after the bottom has been freed, the first shock to detach the charge from the retort wall so that it fall with the bottom, and the second shock to break up the charge and to cause it to fall into a container. A central rod 31 in each frusto-conical retort 1 supports the movable bottom 28, on which rests the inner perforated conical tube 27, attached to which is a ring to support the annular charge. Each rod has a solid head 33 by which it is suspended between two jaws 34, 35 pivotally mounted at 36, 37. The ends of the jaws are engaged by forks 38, 39 carried by rods 40, 41 which are connected by bell-crank levers 42, 43 with racks 44, 45 engaged by a pinion 46. The rods 40, 41 are thus moved in opposite directions, the jaws are opened, and the rods 31 fall, the impact of the heads 33 on the tops 48 of the tubes 27 detaching the charges. The stops to arrest the fall of the charge and movable members 27, 28, 31, 33 are formed by girders 50, carried by cross girders 51 on posts 52 which are vertically movable in guides 53 carried by the frame 54 of the truck. The posts are raised or lowered simultaneously by levers 56, 57, 58, which are controlled by crank wheels 59 driven from the shaft 55. When the retorts are being discharged, the posts are lowered and rest on heavy bedplates 66. The coke collapses into the body 62. The parts of the retort are replaced after discharging by raising the girders 50. The retorts are charged by hoppers carried by an overhead travelling crane. The retorts are heated in the chamber 2 by combustion gases fed through flues from combustion chambers fed from a gas pipe. The retorts open at the top into a gas collector 12 having a movable lid 13, the edge of which forms a gastight joint in the slot 14. The lid 13 is pivoted on an axis 16 fitted with an operating arm 17, through which the lid is rotated by a motor 20 through reduction gear 21 and a pinion 22 and rack member 19. The door 26 is similarly operated by a rack 23 and arm 24.

Patent GB-311791-A (GB)
Title: An improved machine for withdrawing and holding in position convenient for use pins from a magazine or store of pins
IPC: A47F1/04
Filed: 1928-01-14
Abstract: 311,791. Seddon, A. Jan 14, 1928. Packeting pins; unpacking.-Pins assembled in rows in pierced ridges a<1>, a<2> formed in lengths of paper A, are stored in a box E and delivered so that a row at a time is presented for convenient grasping by a roller D mounted in a cover F hinged above the box E, the end of the paper being passed over a bridge piece or roller B and inserted in a slot d<2> in the roller D. As the roller D is rotated the pins are drawn past a transversely-disposed guide C which maintains the rows of pins P in a plane parallel with the plane of the paper until the paper is drawn laterally away from the pins over the roller B where the perforations at the heads of a row of pins are burst and the heads of the pins presented for use through a slot f<3> in the cover F; the points of the pins rest on the ledge or shelf c<1> of the guide C. As shown the guide C is formed from a part of the hinged cover F and the roller B is journaled in ears b<1> integral with the guide : a spring plate d<4> bears against the roller D to maintain the paper taut as it is wound thereon. A tray g<1> may be provided for loose pins in a part G, hinged to the cover F. In a modification the box and part housing the roller D &c. are in one piece, the roller being held in slots therein by a hinged cover and the guide and ledge are pressed cut of the material of the box. The perforations in the paper may be disposed close to the edge of the ridge so that they may be easily burst in which case unperforated intervals in the paper may be of greater pitch than usual so as to preserve the longitudinal tensile strength of the paper. The pins may be arranged in the ridges so that the heads project above the upper ridge as distance equal to one half or one third of the length of the pins and in this case, the upper ridges need not be burst and the feed movement is arrested when the upper ridge reaches the roller B.

Title: Apparatus for lifting and supporting removable lids of vertically disposed vessels
IPC: D06F39/00
Filed: 1948-01-16
Abstract: 632,034. Lifting and lowering. PICKARD, H. M. H., and LEEDS & BRADFORD BOILER CO., Ltd. Jan. 16, 1948, No. 1410. [Class 78 (ii)] An. apparatus for lifting and supporting a removable vessel lid comprises a pillar 1 rotatably and rockably supporting a beam 7, one arm of which supports the lid 9 and the other a counterweight 11, arranged so that the centre of gravity of the whole beam assembly is below the beam supporting point. The beam 7 is freely supported on the pillar 1 by the engagement of a member 3 with a cup 5 which is secured to the beam by members 6. The beam is also connected to the pillar by means of a loose ring 8 which permits a limited degree of beam rocking, the amplitude of which may be predetermined by adjustment of the effective diameter of the ring by a screw (not shown). The counterweight 11 which is adjustable along the beam is set in such a position that it is just overbalanced by the lid so that a slight downward force exerted on the handle 16 is sufficient to raise the lid sufficiently to allow it to be swung away from the vessel. The pillar 1 which is adjustable in height by means of the screw and nut mechanism 2, is rigidly clamped to the vessel at 17.

Title: Improvements in safety brakes for lifts
IPC: B66B5/20
Filed: 1920-01-16
Abstract: 138,601. Curry, J. Feb. 1, 1919, [Convention date]. Catch gear of mine-cage type. - Relates to safety suspending-apparatus for lifts. The ends of a pair of parallel bars 5 secured to the top of the cage 3 are formed with vertical grooves to receive the guide-rails 2 and with horizontal grooves in which slide clamps 8. Each clamp has a jaw 10, Fig. 4, to bear against the outer side of the guide rails and an elongated slot 11 to fit over an eccentric cam 12 carried by a lever 14. The outer end of each lever is formed as a serrated cam 21 which engages the inner side of the guide-rails. The inner end of each lever is pivotally connected to a block 15 which is connected to the hoisting cable 18 and pressed downwards by a spring 17. If the cable 18 breaks, the block moves downwards under the influence of the spring and the consequent movement of the levers applies the jaws 10 and cams 21 to the guide-rails.
Patent GB-856614-A (GB)
Title: Improvements in or relating to controlling apparatus for use with electrical windinggear
IPC: B66B1/12
Filed: 1956-01-17
Abstract: 856,614. Controllers. BLACK, G. A. Jan. 17, 1957 [Jan. 17, 1956], No. 1542/56. Class 38(3). [Also in Groups XXIX and XXXV] Electrically-operated winding mechanism more especially for colliery pithead equipment comprises an electrolytic or other resistance controlling the winding motor and adjusted by an hydraulically actuated piston HO controlled by valves G 1 , G 2 , which are governed by piston and cylinder devices R 1 , R 2 , themselves controlled by pilot valves T 1 , T 2 . Each valve G 1 , G 2  is of the combined relief and unloading type and is fed by one of a pair of pumps P 1 , P 2 , driven by a common motor M. The pilot valves are actuated by a lever F which is pivoted at j to a follow-up system comprising a lever E having an adjustable knife-edge support m and a pivotal connection at h with a lever D which has a fixed pivot g and is linked by a member C to a lever A connected at one end to the piston HO and at the other end, through a link B, to a fixed point d. When the winder is at rest a push-pull moving- coil motor PP energized by a winder-driven tachogenerator and distance cam causes the lever F to depress the pilot valve T 2  whereby the piston HO raises the electrodes EL from the electrolyte. The energization of the motor PP is reversed when a new wind is initiated, causing the electrodes to dip into the electrolyte at an accelerating rate until closure of an electromagnetic by-pass valve K 2  whereafter liquid can escape from the lower side of the piston HO only through an adjustable restriction L 2 . The valve K 2  is controlled either by dashpot operated contacts associated with the piston HO or by contacts in the winder electrical circuit. When the required speed of wind has been achieved the energization of the motor PP is reduced to prevent further movement of the electrodes which are thereafter adjusted as necessary in response to speed error signals fed to the motor PP. A mechanical brake governor, which is used to correct for excess speed, comes into operation under the control of cams when the retardation zone is reached, the cams also causing the pilot valve T 2  to be operated to raise the electrodes. In a modification a further floating lever is interposed between the lever F and the motor PP, this lever being acted upon at its ends by the motor PP and a cam driven by the winder and being linked at its mid-point to the right-hand end of the lever F. Specification 782,023 is referred to.

Title: Printing machine
IPC: B41L45/02
Filed: 1941-02-06
Abstract: 547,026. Printing-apparatus. ADDRESSOGRAPH-MULTIGRAPH CORPORATION. Feb. 6, 1941, No. 1586. Convention date, Oct. 10, 1940. [Class 100 (ii)] [Also in Group XXIII] A hand printing device particularly for printing addresses on record sheets comprises a head 11 with a depending piston-like hand grip 12 to which is pivoted an operating lever 40 for moving a pivoted platen carrying member 20 to press the record sheet against an ink-ribbon covered printing plate mounted in the head 11. The printing plate A, Fig. 4, is inserted in a guide formed by inturned flanges 61, Figs. 6 and 7, of strips 60 secured to the sides of the head and to ensure correct insertion of the plate, it is formed with a notch a<SP>3</SP> to engage a pin 62 carried by the head. One of the strips 60 may have a portion bent inwardly to frictionally grip the edge of the plate to retain it in position. An ink ribbon 80 passing over the plate is wound on removable spools 81 carried in recesses 18 in the head, these recesses being normally closed by a cover plate 90 removably secured by a spring pin 91. The platen-carrying member 20 is pivoted to the head 11 at 30 and is normally locked against actuation, by a slidable latch plate 70 having a shoulder 75 engaging the edge of a plate 25 fixed to the member 20. When the printing plate is fully inserted into its guide, it engages the plate 70 and pushes it rearwardly against the action of a spring 74 to release the platen member 20 which may then be actuated by the lever 40 which is provided with a cam end 44 engaging a roller 50 on the member 20. The platen is in two-parts to permit either or both of two separate groups of lines a, a<SP>1</SP>, Fig. 4, e.g. two separate addresses, to be printed. The platen parts 104, 105 are carried by levers 100, 101, pivoted at 102 to the member 20 and held by springs 107 in contact with a control pin 110 having flattened portions 111, 112 opposite to the parts 104, 105 but spaced 180 degrees apart. In the position shown in Fig. 7, the part 105 only is operative but by turning the pin 110 through 180 degrees, the part 104 is rendered operative and the part 105 inoperative. If the pin is turned through only 90 degrees, printing takes place from both parts of the platen. Specification 547,028 is referred to.

Title: Improvements in and relating to crystallisation process and apparatus
IPC: B01D9/00
Filed: 1939-01-17
Abstract: 523,920. Crystallizing. McGEORGE, W. Jan. 17, 1939, No. 1629. [Class 32] [Also in Group XIII] "Feather" crystals of soluble sulphates of the alkali elements and magnesium are obtained by bringing a strong aqueous sulphate solution in a trough 6 into contact with the cylindrical surface of a drum 11 cooled by circulating refrigerating medium e.g. brine therethrough, the drum being maintained stationary for intervals required for the crystal growth and being intermittently rotated through an angle sufficient to expose a fresh surface to the solution. and to withdraw the immersed surface covered with crystals. The solution is maintained at a temperature high enough to prevent crystallization in a tank 1 heated by burners 2 controlled by a thermostat 3, and is admitted to the trough 6 through a heated valve 8 controlled manually or automatically by a level indicator. The drum is rotated intermittently by an electric motor 15 controlled bv a time switch 16. and is cooled by circulating refrigerant through pipes 12, 13..Crystals are removed bv a scraper 17 at a point where the periphery of the drum is moving downwardly towards the trough so that the crystals remain for a period on the drum to allow hardening before removal.
Patent GB-919516-A (GB)
Title: Improvements in or relating to x-ray diagnosing apparatus with automatic exposure time limitation
IPC: H05G1/46
Filed: 1960-01-15
Abstract: 919.516. X-ray apparatus. SIEMENSREINIGER-WERKE A.G. Jan. 15, 1960 [Jan. 16, 1959], No. 1640/60. Class 98 (1). In X-ray apparatus comprising an automatic exposure timer, and means for reducing the X- ray tube output after part of the exposure period, the said means becomes operative automatically after a time depending on the tube output. In the form shown, an ionization chamber 9 interposed between a film 11 and an object 10 receiving X-rays from a tube 3 forms part of a control member 8. When the optimum dosage is reached, the timer, via a switching member 13, opens a contact 12 in the primary circuit of the H.T. transformer 2 feeding the X-ray tube 3. To reduce the emission current of the X-ray tube rapidly to the desired value, it is preferred to interrupt it entirely and then start it again at its lower value. This is accomplished by the switching member 13, which opens a contact 15 in the circuit of the heater transformer 7, and then (e.g. after 0.4 sec.) closes a further contact 16 which now brings a resistance 14 into the heater circuit. After a further predetermined time of, say, 5 seconds, during which the X-ray tube is run at the lower value of heater current, the member 13 opens contact 12, if it has not already been opened by the control member 8. Simultaneously with the reduction of the heater current, in order to prevent consequent rise in the tube voltage, a resistance 18 is connected into the primary circuit by opening switch 17. The tube voltage is set initially by adjustment of a variable transformer 1 by means of a selector control 4; this regulates at the same time a variable tap 5 on an auxiliary transformer 6 connected with the primary of the heater transformer 7, in such a manner that a particular tube output is always obtained.

Title: Improvements in treatment of chocolate and materials for addition thereto
IPC: A23G1/00
Filed: 1936-01-18
Abstract: A process for improving chocolate consists in adding a small proportion of a polymerized oxidized glyceride containing mostly glyceride substituted with one unsaturated radicle and two saturated radicles, such as oleodistearin glyceride.  The requisite amount of glyceride may be obtained practically by oxidizing and polymerizing cocoa butter or the "premier jus" fraction of beef fat.  The effect of this process is to reduce the time required for couching the chocolate and to raise the bloom-resistance.
Patent GB-1533632-A (GB)
Title: Filtration
IPC: B01D37/00
Filed: 1976-01-16
Abstract: 1533632 Filtering method and apparatus SEITZ-WERKE GmbH 16 Jan 1976 [17 Jan 1975] 01682/76 Heading BID A sensor 24 makes regular measurements of the density of liquid (e.g. beer) emerging from a filter 10, and a unit 21 compares each successive measurement with the preceding one to ascertain a) when the density begins to rise or fall and b) when the density returns to constant level after such rise or fall. Unit 21 controls pneumatic valves 19, 31 in response to conditions a) and b), so that water being displaced by beer is diverted to drain 33, the beer-water mixture, whose exit from the filter produces condition a), is diverted to tank 27, and the pure beer whose exit produces condition b) is diverted to tank 16. When the filter is subsequently flushed with water, a second sequence diverts the beerwater mixture to tank 27 and the water to drain 33. Unit 21 has a manual switch which is set so that the unit controls the valves in the manner appropriate to the first (pre-filter) sequence or the second (post-filter) sequence. The switch could be replaced by an automatic device sensing density or conductivity of liquid at the inlet side of the filter or a timer. Filter 10 shown is a pre-coat filter press, but the method can be applied to a tank filter. The sensor 24, valves 19, 31 and throttle valve 36 which by-passes the sensor form an integral unit demountably connected to other parts at 14, 18, 29 and removably clamped at 23, 30 to the legs 22 of the control unit. Unit 21 includes a digital display of successive measured densities and a plus-minus indicator which shows whether density is rising or calling. The method may be extended to divert different qualities of beer emerging successively from the filter to different tanks, such diversion being made in one step in response to one of conditions a) or b).

Title: Cutting machine
IPC: B24B27/06
Filed: 1975-01-15
Abstract: 1437708 Grinding L J A ROTY 15 Jan 1975 [16 Jan 1974] 1718/75 Heading B3D A machine comprises a rotary cutting tool 1 carried on an arm 2 mounted for reciprocatory movement relative to a work-table 9 on which workpieces 10 are to be mounted, and arm controlling means operatively coupled to the arm and including two compressible resilient stop means 12, 13 and means for progressively compressing one or other stop means as the arm moves to one or other side, respectively, of an intermediate position. The tool 1 is carried at one end of the arm 2, the other end of which carries the motor 3 for driving the tool. The arm is free to pivot about an axis 5 on a lever 6 which is mounted by a pivot 7 on a frame 8 carrying the work-table 9. An adjustable abutment member 16 is mounted on the lever 6 and co-operates with the stops 12, 13 on a bracket 14 secured to the frame. The stops are of rubber or the like and increase in transverse cross-section from one end to the other. When an operator presses on a handle 11, the tool 1 engages the workpiece and tends to roll in the direction of arrow A and the abutment member 16 compresses the lower "progressive" stop 13, the harder the operator presses, the further the tool moves against the action of stop 13 in the direction A. Upon release of the pressure, the tool returns in the direction of arrow B by the force of the compressed stop 13. Adjustment of the abutment member 16 varies the displacement of the tool. In another embodiment, the pivot 7 for the lever 6 and the bracket 14 carrying the stops 12, 13 are mounted on a carriage adjustably secured to slides on the frame 8.
