Title: Improvements relating to universal couplings
IPC: B21B35/14
Filed: 1957-04-11
Abstract: 846,736. Universal joints. UNITED ENGINEERING & FOUNDRY CO. April 11, 1957, No. 11918/57. Class 80 (2). A universal drive coupling between two members 24, 32, for connecting a pair of shafts such as a roll neck 12 and its driving-spindle 16, similarly coupled to a gear-shaft 15 in a rolling - mill, is provided with a spring 39 which, when one of the coupling members 24, 32 is disconnected from its shaft, causes complementary surfaces on the coupling-members to engage and hold the said members axially aligned. This facilitates changing a roll 12, which latter has a slip-out drive connection with the coupling-member 24 by complementary flats 25. The coupling comprises spherically-crowned teeth 34 on the member 32 engaging longer straight teeth in the member 24. The spring 39 is mounted in a recess in the member 32 and presses axially outwards on a plate 42 having a spherical face bearing on a wear-plate in a plate 47 carried by the coupling-member 24. When the roll 12 is slipped out of the coupling-member 24, expansion of the spring 39 presses the rearface of the coupling-member 32 against a surface 53 carried by the coupling-member 24, thus maintaining alignment of the coupling- members 24, 32. The coupling-member 32 is welded at 35 to the spindle 16 and a seal 54 retains lubricant in the coupling.

Title: Improvements in or relating to elevator safety governors
IPC: B66B5/04
Filed: 1940-07-22
Abstract: 542,532. Stop gears for lifts. WESTING- HOUSE ELECTRIC INTERNATIONAL CO. July 22, 1940, No. 12010. Convention date, July 25, 1939. [Classes 78 (iii) and 78 (v)] A device for stopping an elevator when its speed exceeds a pre-determined amount comprises a sheave 11 round which a safety rope 12 passes. The device is mounted in a stationary position near the lift, and the rope is attached to emergency safety or braking gear carried by the lift. The sheave carries two masses 15, 16 pivoted to opposite spokes and coupled by a rod 83. One of the masses has a pawl 99 which engages the teeth 57 of a wheel 14 riding loosely on the sheave shaft 28. A rod 49 pivoted at 55 to the ratchet wheel 14 couples the latter to the outer end of a shoe 13 pivoted vertically at 44., A reduced end of the rod 49 passes through the shoe end, and the connection is through an adjustable spring 48. When the masses 15, 16 fly outward owing to centrifugal force on the speed exceeding an amount determined by an adjustable spring 95, the pawl 99 engages one of the teeth 57  and turns the wheel 14 through a small angle to pull the shoe 13 into the sheave groove and on to the rope 12. The sheave is thus brought to an abrupt stop tempered by the give of the spring 48, and the combined braking effect of the arrested sheave and of the shoe 13 retards the rope 12. At the same time the electric circuit of the operating motor is broken by the shoe end moving away from contacts 103. The shoe is normally biassed away from the rope by a balance weight 60 on the ratchet wheel 14. A cushion 74 lessens noise due to impact of the masses 15, 16.

Title: Apparatus and method for making a metal print drum
IPC: B30B11/00
Filed: 1974-03-19
Abstract: 1470584 Moulding metal printing cylinders by isostatic compression MOHAWK DATA SCIENCES CORP 19 March 1974 [9 May 1973] 12202/74 Heading B5A [Also in Division C7] A printing cylinder having raised characters on its outer surface is formed by isostatic compression of metal powder in the apparatus shown in Fig. 1, in which an expandable bag 32 may be pressurized to compact metal powder against a compressible sleeve 40 having character depressions 49 formed in its inner surface, the sleeve 40 being supported by rings 34, 38 and 42 between upper and lower rams 14 and 16 and an outer metal enclosure 20. A support cylinder 26 within the expandable bag 32 has bores 47 for the supply of pressure fluid 48 (glycerine) to the interior of the bag, via a bore 22 in the lower ram 16 and hydraulic pressure multiplier 52, from an hydraulic pump 54. To form the printing cylinder, the mould 18 comprising parts 26, 32, 34, 38 and 40 is removed from between upper and lower rams 14, 16, and filled with metal powder, filling being facilitated by vibration. The top ring 42 is then placed on the mould 18, which is then positioned between rams 14, 16 and lowered into enclosure 20. The metal powder is precompressed using the upper ram 14, after which the bag 32 is pressurized to assist compression, the pressure produced by the ram 14 being maintained higher than that produced by the bag 32. The mould and compacted metal drum are then removed by raising ram 16, and the mould disassembled to give the drum still inside the ring 38 and sleeve 40. The drum is machined, whilst still inside the ring 38, to the required internal diameter. The drum and sleeve are then pushed out of the ring 38, and the sleeve 40 removed from the drum by cutting. Before sintering, a mounting core which has also been produced by isostatic compaction of metal powder is inserted in the drum, and the whole sintered to give the final cylinder. As described with reference to Fig. 3, not shown, the character sleeve 40 may be produced by injection moulding of a glass fibre filled polyurethane composition.

Title: Improvements in and relating to supplying liquids at constant rates
IPC: D01D1/09
Filed: 1937-04-29
Abstract: 494,686. Liquid - supply systems. KINSELLA, E. April 29, 1937, No. 12241. [Class 102 (ii)] A liquid 2 is displaced from the outlet 6 of a container 1 at a constant rate by means of a second liquid 3 introduced into the container from a tank 4 by a measuring pump 5 and the container 1 is periodically recharged with liquid 2 from a container 10 by means of a pump 9 which feeds liquid 3 from the container 1 to the con. tainer 10, thus displacing liquid 2 from the container 10 into the container 1, the container 10 being subsequently recharged with liquid 2 from a tank 15, the liquid 3 being displaced into a tank 4. When charging the container 1, valves 8 and 12 are open and valves 14 and 17 closed. A valvecontrolled connection from the tank 4 to the inlet of the pump 9 may be provided so that the pressure in the container 10 may be raised to that in the container 1 before the recharging begins. Fig. 3 shows apparatus for automatically effecting the recharging of the container 1 and is intended more particularly for the displacement of rubber latex by oil. The valves 12 and 14 of Fig. 1 are replaced by non- return valves 112 and 114 respectively. The oil connection 16 between the tank 15 and the container 10 is controlled by a spring-closed needle valve 117 operated by a float 24 which also co-operates with a float 23 in the container 1 to control the circuit of the motor of the pump 9 by means of series-connected switches 22, 21 respectively so that the pump will operate only when the latex level is low in container 1 and high in container 10. When the pump 9 is first set in operation, oil is fed from the tank 4 through a valve 119 to the container 10 until the pressure in the container 10 is approximately equal to that in the container 1. The valve 119 comprises a casing 63 in which operates a piston 64 with a hollow stem 65, the two sides of the piston communicating by passages 66, 67 with the inlet and outlet of the pump. As, the pressure in the container 10 rises, the piston moves up and connects the containers 1 and 10 by way of a port 68 in the stem 65 and a recess 69 in the casing communicating with a pipe 7. A non-return valve 20 then closes and the pump feeds oil from the container 1 to the container 10. The pump 5 is of the dual type comprising a pump 71 having a greater delivery rate than a second pump 72. A balance valve 73 controls a byepass from the outlet to the inlet of the pump 71 so as to maintain a constant pressure relation between the two sides of the pump 72. If the apparatus is used for two liquids which mix, they are separated by pistons in the containers 1 and 10. Specification 182,154, [Class 110 (ii)], is referred to.

Title: Improvements in or relating to the manufacture or recovery of substances from residual liquors of the beet sugar industry
Filed: 1926-05-17
Abstract: 265,831. Jackson, L. Mellersh-, (Larrowe Construction Co.). May 17, 1926. Glutamic acid; betaine hydrochloride.-Glutamic acid is obtained from the residual liquors of the beet sugar industry by raising the temperature of the liquor after the betaine hydrochloride and alkali metal chlorides have been separated out by the addition of hydrogen chloride in known manner. In an example desaccharified molasses is saturated with hydrogen chloride gas at a temperature below 70 C. On standing, a precipitate settles and is filtered off, and consists chiefly of potassium chloride and betaine hydrochloride, which are separated in known manner by extraction with alcohol. The mother liquor is then heated to a temperature below 95 C., and on cooling glutamic acid hydrochloride crystallizes out. After the glutamic acid hydrochloride has been separated a further yield of betaine hydrochloride and inorganic salts may be obtained by evaporating the main body of the solution in vacuo, and a still further yield of betaine hydrochloride may be obtained by evaporating till the water is nearly all driven off and adding the residue to absolute alcohol.
