Abstract: 645,244. Lubricating. FAIRWEATHER, W. C. (Singer Manufacturing Co.). July 10, 1948, No. 18622. [A Specificationwas laid open to inspection under Sect. 91 of the Acts, Oct. 14, 1949.] [Class 12 (iii)] [Also in Group VII] In a sewing-machine oil is supplied to the thread-carrier raceway 9 of a rotary loop-taker 7 by a lubricating system comprising ducts 61, 62 leading from the raceway to a bore 48 in the loop-taker shaft 14,.conduit means connected to the bore at the end of the shaft remote from the loop-taker, a pump to supply lubricant to the conduit means, a byepass 53, 56 connected to the conduit means, and means for regulating the flow through the byepass. Oil from a reservoir 29, connected to a main reservoir 32, is carried by the loop-taker gearing 25, 26 to a pocket 38 in the loop-taker shaft bearing 19. Oil is pumped from the pocket by a helical groove 40 in the shaft to a compression chamber 44. The chamber leads to the conduit means which comprise ducts 49, 50, a distribution chamber 52, and a spigot 46 communicating with the bore. The byepass leads from the distribution chamber and returns oil to the reservoir and the flow in the byepass is regulated by a screw 54 having a reduced end 55. When the screw is in the position shown in Fig. 1, most of the oil is returned to the reservoir, but when the screw is lowered its reduced 'end blocks the byepass and all the oil passes to the bore which contains a filter-wick 59. Specifications 500,704, 557,094, and 558,264 are referred to.

Title: Netting for captive balloons
IPC: B64B1/40
Filed: 1920-07-05
Abstract: 146,852. Riedinger Ballonfabrik Augsburg Akt.-Ges., A. June 22, 1918, [Convention date]. Captive balloons; cars.-The anchoring cable P<1>, and the car P<2> of a captive balloon are connected to the envelope through systems of looped cords with interposed rollers r or similar members so that, for all ordinary attitudes of the balloon, the forces at P<1> and P<2> pass approximately through the same points A, K on the longitudinal axis of the balloon. The rigging is designed so that, when the balloon is being hauled in and. the nose consequently dips, the forces at P<1> and P<2> are displaced sufficiently to the rear to ensure the restoration of the balloon to its normal position against the friction of the rollers r when the winding stops. To limit the backward tilting of the balloon when the force at P<2> is increased relatively to the force at P<1> owing to the presence of an additional observer in the car or to loss of gas in the envelope, cords z are provided which, as they become taut, cause the resultant forces to pass ahead of the points A, K.

Title: Sound-absorbing wall element
IPC: E04B1/84
Filed: 1974-04-29
Abstract: 1442696 Laminated sound-absorbing panels HERMANN HEMSCHEIDT MASCHINENFABRIK 29 April 1974 [5 Dec 1973] 18738/74 Heading B5N [Also in Divisions E1 and F2] A sound-absorbing wall element is formed of pieces of reinforced pneumatic rubber tyres which have been disintegrated, as by shredding or by cutting, the pieces being bonded together by vulcanization or by means of an adhesive to form an irregular porous structure. Preferably, the size of the majority of the tyre pieces is between 3 and 30 mm. in length. Where the tyres have been cut into chunks rather than lengths, however, the above size range refers to the maximum dimension. The volume of actual tyre pieces in each wall element is preferably not more than 60% of the wall element, the remainder being air in the pores. The density of a wall element thus formed is less than 0À6 g./cc. and this has been found to attenuate sound effectively. In Fig. 1, a layer 1 of the wall elements, which layer is to face the sound, is attached by means of a cement or adhesive to a supporting frame 2 formed of sheet metal sections. Cavities 3 in the frame 2 are filled with loose pieces, e.g. shreds, of disintegrated reinforced pneumatic rubber tyres. In Fig. 2, the layer 1 is fitted into a supporting frame 2 and is backed by a muffling element 4 of, e.g. mineral wool. The space behind the muffling element 4 forms a reverberation chamber 5 for reflecting some of the unabsorbed sound which then reenters the muffling element 4 and the layer 1 a second time from the rear. This embodiment may be used to muffle the sound of traffic which, on major roads, embraces a wide range of frequencies.

Filed: 1927-07-15
Abstract: 298,680. British Dyestuffs Corporation, Ltd., and Walker, E. E. July 15, 1927. Phenol-aldehyde condensation products.-In a process of forming condensation products by condensing a phenol first with an aliphatic ketone and then with an aliphatic aldehyde, the second or both reactions being effected in an alkaline medium, the alkali is neutralized with acid after the second condensation, until the aqueous layer after agitation with the oily layer shows a pH value of 5-7 inclusive, and the oil is then separated and crystallized. In examples, (1) dihydroxydiphenyldimethyl methane, obtained by condensing phenol with acetone, is dissolved in caustic soda solution and mixed with 40 per cent formaldehyde; after standing for 4 days, the mix is neutralized with aqueous hydrochloric acid, the pH of the aqueous layer after agitation as previously described, being adjusted to 6; the oil is washed and allowed to crystallize; (2) the process is effected as in example (1), but the oil is " seeded " with a small quantity of crystals from a previous batch to aid ra.pid crystallization. Specification 261,522 is referred to.
Patent GB-654891-A (GB)
Title: Improvements in or relating to injection moulding machines for plastic material
IPC: B29C45/53
Filed: 1948-07-13
Abstract: 654,891. Injection-moulding machines. LESTER ENGINEERING CO. July 13, 1948, No. 18841. [Class 87 (ii)] The material is fed through an opening 48 into a large bore 15a in the injection cylinder 15, whence it passes into an adjacent coaxial small bore 61a in a liner 61, then into a cylinder extension 26 and out through the injection nozzle part 27 into the mould. Within the bore 15a reciprocates a tubular plunger 52, and within the tubular plunger reciprocates a solid plunger 56. The plunger 56 is shown in its retracted (rightward) position and the plunger 52 in its fully advanced (leftward) position. In the position shown (but with the plunger 52 retracted to the right) there is an annular space between the end of the plunger 56 and the liner 61, and through this annular space the plunger 52 forces the material when it moves leftward to the position shown, the plunger 52 coming to rest with its end abutting against the liner 61. The plunger 56 then moves leftward from the position shown and forces the material from the bore 61a through holes 41 in a vertically-reciprocable gate 22 into channels 40 in a liner 31, whence the material flows into extension 26. The plungers 52, 56 are operated by two hydraulic cylinders (Fig. 2, not shown), and the gate 22 is raised and lowered by a third hydraulic cylinder 42. When the gate is up, the holes 41 and channels 40 are out of register ; when it is down, they register. The pressure applied to the plunger 56 is greater than that applied to plunger 52 or to gate 22. The three hydraulic cylinders are under the control of valves operated by solenoids in an electric circuit (Fig. 7, not shown), including a timer, the switches in the circuit being controlled by movement of the hydraulic plungers and the operation being continuous and cyclic. The sequence of operations, beginning at the position shown (bore 61a being full of heated fluid plastic material and the gate being down, i.e. open,) is as follows: (1) plunger 56 advances to the left to discharge the material through the gate ; (2) plunger 52 retracts to the right, and material from hopper 45 falls into the annular space around plunger 56 ; (3) the gate 22 rises (closes) ; (4) plunger 52 advances to the left for a part of its stroke, compressing the material in the annular space around plunger 56. A pause ensues, during which the material is heated and compressed ; (5) plunger 56 retracts to the right ; (6) plunger 52 completes its leftward stroke, forcing the material through the annular gap between liner 61 and end of plunger 56 ; (7) the gate descends (opens). This is the position shown. The cycle then recommences. Plunger 56 has an internal heating channel 57. Cylinder extension 26 has an internally-heated core 32 and is heat-jacketted at 25. Cylinder 15 is heat-jacketted at 17. A channel 62 and another channel 63 in the gate allow escape of air from bore 61a. The mould may be that shown in U.S.A. Specification 2,243,968.

[Also in Division H5] In fluid sterilization apparatus (see Division H5) comprising a chamber through which fluid to be sterilized passes, having a lamp projecting into the chamber and being adapted to emit ultra-violet rays to irradiate the fluid, the lamp projecting through a wall of the chamber, a fluid tight sealing means is fitted between the wall and the lamp and comprises a mouldedin-place seal of resilent material which adheres to the surface of the lamp. The preferred material is silicone rubber. Preferably as shown the lamp is tubular, the chamber 11 being elongated with the lamp 12 supported centrally in it by the interaction of mouldedin-place gaskets 48 and annular elements 49, 52 which by means of screws 53 are tightly clamped on the gasket. In alternative sealing arrangements, Figs. 9 to 11 (not shown), the moulded-on seal is provided on its face facing away from the chamber 11 with an apertured disc bonded to it. A locating means comprising a removable retaining ring is provided in a groove in the housing to locate the lamp. The seal may have concave or cup-shaped inner surfaces so that the pressure of the fluid in the chamber tends to force the seal against the wall. Alternative locating means (Fig. 10) comprises a sleeve which co-operates with a threaded cap 54 to locate the tube 12. An 0 ring may be fitted in to a groove around the sleeve and disc to complete the seal. In Fig. 11, the disc is replaced by a cylindrical member into a central orifice in which the moulded-in-place seal fits. The cylindrical member is positioned by means of a sleeve and threaded cap and sealed by an 0 ring as in the previous alternative.

Abstract: 1,093,880. Conveying and classifying workpieces. REPUBLIC STEEL CORPORATION. May 5, 1965 [May 5, 1964], No. 18993/65. Heading B8A. [Also in Division G1] Automatic workpiece inspecting, defect marking and classifying apparatus includes a storage and feed rack assembly 11, an entrance section 12, an inspection station 13, an exit section 14 and a segregating bin assembly 15. A control centre 152 controls and co-ordinates the sections 12-14 and the bin assembly 15. A number of workpiece propelling assemblies 25, Figs. 3, 4 (not shown) are able to move in any direction perpendicular to the path of travel of the workpieces and bent or cambered workpieces are thus able to be propelled past an inspection station without having been previously straightened. Each propelling assembly (25) includes a rectangular float plate (26) which is carried by vertical and horizontal springs (27) and which supports a circular table (28). This table is rotatable on the plate (26) and carries a motor driven roller whose axis of rotation is adjustable by means (40-43) connected to the table (28). The angle at which the roller is set is determined by the diameter of the workpiece (18) and controls the helical travel of the workpiece through the inspection station. Guide members (51) for the workpiece are movable laterally for various sizes of workpieces. Over each of the assemblies (25) is provided an assembly (56) which holds down the workpiece by idler rollers (59, 60) supported on a pneumatic cylinder device (57). The inspection station 13 includes two propelling assemblies (25) and two pairs of hold down arms (89, Figs. 5, 7) together with a search probe (104, Fig. 8, not shown) midway between the pairs of arms, the probe being spring mounted within a frame (101) which also carries a motor-driven carbide cutter (112) for marking defective workpieces.

Title: Improvements relating to the alcoholic fermentation of sugar-containing liquids
IPC: C12P7/06
Filed: 1934-06-27
Abstract: In the process of alcoholic fermentation of sugar-containing liquids according to the parent Specification, wherein the specific cellular saturation of the yeast, that is, the concentration at which the vegetative functions have ceased, is maintained constant by allowing the fermentation to be continued to the end, removing all the yeast present in the liquid, and using this yeast again for the fermentation of a fresh portion of liquid such that the total resultant volume is equal to the first, the cellular saturation is maintained at a value not exceeding 10 kilograms of yeast having 75 per cent of water to 1000 litres of sugar liquid to be fermented. This may be done either by partial or total elimination of materials, especially nitrogenous materials, which assist the growth of the yeast cells, or by adding to the sugar liquor substances which impede the growth of the yeast cells without arresting their alcoholigenic action. Examples of substances of the latter kind are furfural, ulmic acids, ferric chloride, and zinc sulphate.  The sugar liquor may be preliminarily deaerated by the injection of a gas unfit for respiration, for example, carbon dioxide, nitrogen, or hydrogen. Examples are given.

In a typical operation, a casing is shirred by rollers S and held by rollers 19 and is then restrained by the descent of member 51. Piston-operated grippers 63, 65 engage the casing and are moved backwards on a carriage 30 to tension the casing. During this retraction the severing means 21, 23 descend and score and/or cut the casing; further retraction causes severing. The members 51, 21, 23 disengage, thus permitting the severed portion to advance as the grippers 63, 65 retract. At the end of the cycle, the grippers disengage and the carriage returns, whereupon a compressor arm 25 descends and pushes the severed length towards clamp K to re-establish shirring. Control mechanisms and severing means constructions are described.

Title: Improvements in or relating to a power assister for manually operated mechanisms
IPC: G08B9/08
Filed: 1948-07-16
Abstract: 673,533. Order-telegraph signalling apparatus. CHADBURNS (LIVERPOOL), Ltd. and BAMFORD, D. C. June 10, 1949. [July 16 1948] No. 19084/48. Classes 40 (i) and 118 (ii). In a manually operable mechanical remote control installation (e.g. mechanical telegraph, steering mechanism transmission system for controlling valves, ventilators, etc.), the operating handwheel has a hand-grip part proper which is permitted limited movement relatively to the wheel in relation to switch mechanism controlling a power assister, so that pressure on the hand-grip automatically brings the power assister motor into operation. As shown in Figs. 1, 3 and 5, the transmitting handwheel 12 of a ship's "order" telegraph drives the receiver pointer 14 directly through shafts 16 and gears 17. In applying pressure to the hand-grip 29, which is carried independently of the handwheel on a member 30 pivoted at 31, about 5 degrees of most motion, determined by the movement of an abutment 33 in slot 32, is first taken up, and in so doing the abutment closes one of a pair of contacts 40, 41 and 42, 43 connected through slip-ring on the handwheel shaft to an electric motor 20. Dependent on the contact pair closed, the motor rotates shafting 21 in the correct direction to give power assistance to the handwheel. A magnetic clutch 23, also operated by the contacts, is included in the motor drive, to ensure the drive is removed immediately it is desired to bring the handwheel to rest. The clutch also relieves the installation of the assister load when manual operation alone is required. Spring loaded lever 37 engaging a roller member 34 restores the hand-grip to the central position. To prevent hunting when the handwheel is brought to rest, delayed action relays may be included in the motor and clutch circuits, a dash-pot device may damp the handwheel motion, or the magnetic clutch may include lost motion. A similar arrangement including motor 25 provides power assistance for the "revolutions required" handwheel 13. According to the Provisional Specification, the contact system may comprise a leaf spring which is displaced by movement of the handwheel to contact one of two screw contacts, the centering mechanismcomprising a star wheel co-operating with spring loaded rollers or notches which snap into engagement with the teeth. Specification 650,691 is referred to.
