Title: Improvements in or relating to hydraulic gears
IPC: F16H39/36
Filed: 1923-12-13
Abstract: 227,266. Lendl, O. Dec. 13, 1923. Clutches and speed-varying mechanism.- Hydraulic variable-speed gearing comprises driving and driven gear-wheel pumps, the capacity of which is varied by relative longitudinal adjustment of the pump members. The driving shaft 2, Fig. 1, is connected to internally-toothed rims 5, 6 co-operating with gear-wheels 7, 8 mounted on a shaft 10 axially adjustable in a rotor 13 connected to the driven shaft 31. Between the rims 5, 6 is an extension 15 of the rotor, and between the wheels 7, 8 is a spacing member 9. The pair of pumps 5, 7 and 6, 8 are connected in such a manner that the suction of each pump is connected to the delivery of the other, and the pump 6, 8 is twice the width of the pump 5, 7. In the position shown, the capacities are equal so that the pair supply no liquid to a conduit 49<1>, Fig. 10. As the shaft 10 is adjusted in the direction of the arrow 14, the capacity of the pump 5, 7 diminishes and that of the pump 6, 8 increases so that an increasing quantity is supplied to the conduit 49<1> and withdrawn from a conduit 48<1>. The driven pump consists of a pair of gear-wheel pumps 16, 18 and 17, 19 similar to the other pumps, except that the toothed rims 16, 17 are fixed. In the position shown, the capacity of the driven pair of pumps is a maximum, which gradually decreases by adjustment of the shaft 10 as the capacity of the driving pair increases, the shaft 31 being thereby driven at an increasing speed. The conduits 48<1>, 49<1> are provided with slides adjustable by a rod 59 and having members 52<1>, 53<1> which are operated to interrupt and reverse the drive, other members 70<1>, 71<1> serving to brake the shaft 31 when required. Automatic leakage-replenishing valves 65 are provided.

Abstract: 1,061,143. Sheet delivery apparatus. J. V. BAILEY, G. C. FORTIN, M. C. STANLEY and J. G. ARNOLD. Aug. 15, 1963 [Aug. 16, 1962], No. 31406/62. Heading B6H. A paper web 11 fed at constant speed is cut into sheets, each sheet 116 is grasped by a pair of accelerating rollers 117 just before it is cut from the web and, when the sheet is cut, accelerates it to move at a speed higher than the web speed and passes it to a pair of transport 123 which transport the sheet at a constant speed equal to the accelerated speed imparted thereto by the rollers 117. The sheets cut from the web are thus separated from each other for subsequent processing. The sheets are cut by a fixed knife 113 and a rotary knife 112 having two blades 114, 115, and the rotation of the knife 112 is synchronized with the individual printed designs on the web e.g. by photo-electric or other means which co-operate with printed marks or perforations along the edge of the web. The accelerating rollers 117 are driven by elliptical gears or by crank mechanism from a constant-speed shaft so that the speed of the rollers varies cyclically.

Title: Improvements in or relating to dyestuff preparations
IPC: C09B67/42
Filed: 1933-11-13
Abstract: Preparations of organic dyestuffs, colour lakes, or organic pigments, are made by diluting the dye with water-soluble substances obtained by the incomplete hydrolytic degradation of cellulose by means of strong mineral acids, such products corresponding approximately to the dextrine obtained from starch. The said products may be mixed with the dyes or pigments in any desired proportions, and used in dye-baths.  The degradation products may be obtained by treating cellulose or wood, straw, peat, and residues from the extraction of tanning agents from tan woods, with strong mineral acids such as hydrochloric, nitric, hydrofluoric and sulphuric, preferably in liquid form, but also where possible in the gaseous state, at temperatures at which the material is not destroyed.  The excess acids are removed from the filtrate containing the soluble degradation product by heating or by precipitation with lime, and dissolved heavy metal compounds and other impurities by precipitation.  The cellulosic material may be treated initially for the preparation of oxalic acid followed by the subsequent degradation.  British Specifications 184,627, [Class 2 (iii)], and 360,015, German Specification 577,764, and U.S.A. Specifications 1,883,676 and 1,883,677, are referred to.  According to the examples, product obtained by the degradation of wood with hydrofluoric acid are used to dilute Rhodamine B extra, Victoria blue B, Rhodamine 3 B extra, and Crystal violet powder; the product obtained by treating the residue after nitric acid treatment to obtain oxalic acid, with hydrofluoric acid is used to dilute Methyl violet N bluish.  The cellulosic products are stated to be polysaccharides similar to dextrin.ALSO:Products obtained by the hydrolytic degradation of cellulose, wood, straw, peat or residues from the tanning extraction of tan woods, with strong mineral acids such as hydrochloric, nitric, hydrofluoric, and sulphuric, used in the liquid form or gaseous state where possible, at temperatures insufficient to cause the destruction of the material, said products having the properties of polysaccharides similar to dextrin, are used to make dye preparations of organic dyes and pigments.  The products are isolated from the filtrates by blowing off the acid if gaseous, or by neutralizing and precipitating, and are soluble in water, slightly deliquescent and have a low reducing action on Fehling's solution.  The cellulosic materials may be initially treated with nitric acid to produce oxalic acid, followed by the hydrolytic treatment.  German Specification 577,764, U.S.A.

Filed: 1950-12-29
Abstract: 695,143. Protective cut-out arrangements. BENDIX AVIATION CORPORATION. Dec. 29, 1950 [Dec. 29, 1949], No. 31623/50. Addition to 641,671. Class 38 (v) In a modification or improvement of the system of the parent Specification in which a generator 1 is protected against excess voltage by a safety switch or circuit-breaker having its trip coil 25 connected across the field winding 4 of the generator, a differential relay 44 responsive to unbalanced current conditions in the output circuit of the generator is provided to cause the tripping of the switch under earth fault conditions. The relay 44 has a-coil 48 in shunt with a resistance 52 in the output circuit, and a coil 49 supplied by a potentiometer 54 connected across the interpole winding 5 of the generator. Under normal conditions the coils 48, 49 have equal and opposing effects, but on the occurrence of a fault causing unbalance, the predominating coil closes contacts 46 or 47 to short circuit a resistance 27 which is in series with the trip coil 25. This causes an increase in the voltage across the coil 25 and the coil trips the switch, which at contacts 7 - 9 and 13 - 15 opens the field circuit and at contacts 30 - 32 opens the circuit of the operating coil 34 of a main circuit-breaker 36 in the output circuit, the arrangement of the safety switch being similar to that in Specification 644,437.

Abstract: 1,035,054. Transistor video amplifiers. CSFCOMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. Aug. 12, 1963 [Aug. 10, 1962], No. 31810/63. Heading H3T. A transistor final video amplifier stage has a variable emitter resistor for gain control shunted by a capacitor and a resistor in series to compensate for variations in the response curve due to operation of the gain control. Fig. 1a shows such a stage feeding a C.R. tube from terminal 12, the network 6, 7 providing the necessary compensation for operation of the gain control 5. If the emitter voltage requires to be adjustable to fit the driver stage voltage, the resistors 3 and 5 are interchanged and their common point returned to a negative supply (Fig. 1b, not shown). To preserve the black level (Fig. 3a), a parallel circuit of resistors 16 and 17 is connected from the emitter to the negative supply. Adjustment of 5 and 17 simultaneously alters the contrast without affecting the black level, the latter being controlled by 16. This circuit can be modified to allow for a PNP driver stage (Fig. 3b, not shown). The contrast control can also vary the bias on the driver stage. The invention is applicable to both positive and negative modulation systems.

Abstract: 975,936. Shoe manufacture. FORMULAST CORPORATION. Sept. 16, 1960 [Sept. 16, 1959; March 15, 1960], Nos. 31973/60 and 9179/60. Divided out of 933,183. Addition to 857,012. Heading A3B. The method claimed in the parent Specification is carried out on a conveyer installation with last supports, the conveyer being associated with two spaced heaters for preheating the shoe and heat conditioning the cement respectively, and a cementing station being located between the heaters. One apparatus used is also shown in Specification 933,183. Fig. 3 shows diagrammatically an installation for one process, with the various operations carried out at the numbered stations as follows. (1), Stiffener assembled in upper and upper placed on conveyer, and mulled at 80, (2), insole tacked to last, upper placed on last, last mounted on conveyer, (3), pulling over, (4), side lasting, (5), heel seating and forepart lasting, (6), toe lasting, (7) and (8), upper trimmed, insole tacks removed, upper bottom pounded flat and roughened, (9), shank stiffener and bottom filling applied, and sole attached to conveyer. The upper bottom is then heated in oven 60, to dry the upper following the milling and to perform the first step in the method of the parent Specification, i.e., preheating the lasting margin to form a heat reservoir. Cement is applied at station 10, and the second step of the method of the parent Specification, i.e. heat conditioning the cement, is performed in oven 64. Thereafter the cement on the shoe cools, so as to become tacky, the cement on the sole is reactivated by heater 68, at station 11 the sole layer secures the sole and partially cleans the shoe, and at 12 the heel is secured. The whole process takes about 15 minutes. Station 9 is dispensed with when making low-heeled shoes, and heater 68 is removed or reduced if it is likely to damage the material of the sole. The apparatus may also be used without milling and lasting stations, lasted uppers and soles passing through heater 60 &c. Fig. 2 shows conveyer chain 12 driven by motor 26 through reduction gearing 28 and coupling 30. Micarta pads 32 carried by the chain each carry a part 38 to support a last. A sole is positioned on a pad by raising collar 42 against spring 44, and is then held in position by the collar. Specification 975,937 also is referred to.

Abstract: 622,843. Lift cage door locks. EXPRESS LIFT CO., Ltd., and KRUGER, S. Oct. 29, 1946, No. 32055. [Class 78 (iii)] In a lock mechanism for a lift well door or gate of the kind in which a latch is adapted to be inserted and locked in a lock box, the parts within said box comprise a plurality of independently movable ward levers adapted to be moved by the said latch, on insertion of the latch within the box, to a determinate configuration which permits the movement of a lock plate either into a locking position in which the ward levers 'are prevented from movement and the latch cannot be withdrawn from the box, or out of the said locking position so that the ward levers are then free to move and the latch can be withdrawn from the lock box, said lock plate being movable independently of the movement of the ward levers and being adapted to be moved into or out of the said locking position by external means, and at least one of said ward levers or said locking plate is adapted to control an electric circuit. Wards 8-12, Figs. 2, 3 and 9, independently mounted on separate bearings mounted on a pivot pin 13 are adapted to engage the latch member 24, Figs. 5, 7, so that wards 8, 10 rest on the top faces of arms 25a, 26a, and ward 9 rests on the top of the connecting member 27, the underside of which is engaged by wards 11 and 12 fastened together as shown in Fig. 9, the arrangement being such that pivotal movement of the spring loaded latch 24, to disengage its upstanding portion from the upper internal portion of the entry bush 39 so that the gate may be opened, is prevented when the wards are locked in their latch engaging position. Contacts 15, Figs. 2 and 3 are bridged by a member 14, secured to the ward 9, when said ward is in its latch engaging position and an electrical circuit (not shown) operates a member carried on the lift cage which member moves a wheel 6 and an arm 3 which rocks a shaft 4 to which is secured a locking plate 7 which engages the upstanding portions of wards 8 and 10 and locks all the wards in their latch engaging positions, said plate having attached thereto a member 16 which forms a safety half-lock stop against which wards 8 and 10 abut after a slight movement towards their unlocked position when released by a slight unlocking movement of a plate 7. Attached to the plate 7 is a member 18 which, when the plate is in its locked position, bridges contacts 19 and operates a remote contactor (not shown) which allows the lift driving motor to be operated, accidental bridging of the contacts 19, when the gate is unlocked, being prevented by engagement of the plate 7 in its unlocking position by the upstanding portions of wards 8 and 10 which are then out of their latch engaging position. The wards, which are of different shape to prevent tampering, may be unlocked in an emergency by the insertion of a key through a hole (not shown) in the rear of the lock box.
