Title: Improvements in or relating to the moulding of articles from powdered materials
Inventor: COOMBER HORACE JAMES
IPC: B30B15/30
Filed: 1961-04-21
Abstract: 939,773. Feeding powdered materials to moulds. GENERAL ELECTRIC CO. Ltd. April 17, 1962 [April 21, 1961], No. 14627/61. Class 87(2). In a process for moulding powdered material the latter is fed under gravity, at a constant rate, into the mould 14, which is supported with the aperture uppermost, while the rigid base 4 of the mould and support assembly is subjected to a regular and constant tapping and the mould support 1 is rotated about a vertical axis through the aperture 6 so that the material is urged towards the mould walls. The mould support 1 is mounted on a vertical shaft 16 which has a platform 25 welded to it. Rollers 31, 33 mounted on the bellcrank 27 co-operate with the under side of the platform 25 and a cam 35 respectively. The shaft 16 is oscillated vertically, being raised by the cam 35 and then forced down against the anvil 48 by the spring 42. The shaft 16 may be rotated either independently of or simultaneously with the vertical oscillations. Specification 939,772 is referred to.

Title: Power transmission apparatus
IPC: F16D31/08
Filed: 1945-06-08
Abstract: 594,689. Variable-speed gear. WALLACH, G. June 8, 1945, No. 14623. [Class 80(ii)] In an epicyclic variable-speed gear, the driving member carries pairs of planet wheels forming gear pumps, braking of which, by controlling the inflow of oil towards the meshing points of the teeth, allows one gear of each pump to drive the driven shaft sun wheel. Pairs of gears 17, 18 on spindles 20 secured to a housing 7 on a driving shaft 5, form gear pumps in conjunction with the blocks 25 secured at the inner periphery of the housing 7. A spider 35 rigid with a sleeve 34, which is movable axially by a fork 49, has slots 36 engaging with arms 40 of the gates 33. The housing 7 is extended to form an oil supply chamber 12 closed by a cover plate 13 which has float chambers 59 and floats 65 to regulate the radial depth of oil in pump chamber 11 when the housing 7 is rotating. The variation in speed between the driving and driven shafts 5, 6 is obtained by moving gates 33 to vary the quantity of oil to the pumps, the latter having no outlets except the clearance between their teeth at the points of mesh. In a modification, the fork 49 is arranged to operate an electrical circuit to fully open the engine throttle when the variable-speed gear is in operation.

Title: An improvement in internal combustion engines specially applicable to engines of thehigh compression-ignition type working on the two-stroke cycle
IPC: F02B75/02
Filed: 1936-05-25
Abstract: 475,584. Two-stroke-cycle opposed-piston engines. HUNT, F. O. May 25, 1936, No. 14678. [Class 7 (ii)] Pairs of pistons 3, 4 in axially-aligned cylinders 1 drive a central shaft through pin-and-slot mechanism. The adjacent pistons 3 are rigidly connected to a slotted-crosshead in which slides the bush 6 enclosing the crank-pin 7. The remote pistons are of two diameters the larger portions being connected by rods to a second cross-head in which works a crankpin diametrally opposite to the crank-pin 7. The stepped pistons work over a fixed cylindrical frame member 13 forming low- and high-pressure pump-spaces 12, 18 respectively. Air induced in the pump-space 12 is transferred to the reservoir 16 by way of valve 15, and hence to the pump-space 18 through valve 17. After further compression most of the air finds its way past a valve 19 to the combustion chamber. Part of the air, however, is conveyed by a pipe 27 to an air-oil spraying valve, which together with an oilpump injection nozzle is operated from a cam on the crank-shaft. The wall of the pump space 12 is formed with a helical rib having a cover 14. The valve 19 relies on inertia for its closing movement.

Abstract: 705,083. Refrigerators; cooling milk. GASCOIGNES (READING), Ltd. June 17, 1952 [June 22, 1951], No. 14879/51. Classes 29 and 64(3) Ice is formed on evaporator coils 2 in a water tank 1 to act as a cold accumulator and part of the chilled water withdrawn by a pump 9 is forced through jets 11 directed towards the coils 2 to agitate the water in tanks 1 and so increase the heat transfer between the water and the ice. Churns 4 stand on a grating 3 and the remainder of the water withdrawn by pump 9 flows through pipes 17, 18 and cocks 19 to cooling heads, Fig. 3, for the churns. Each head comprises an annular chamber 26 fed through one or more pipes 29 connected to pipe 18, the water overflowing through openings 28 into a peripheral gutter 24 from which it flows through openings 25 down the churn walls back to the tank 1. A lid 5 having stays 6 can be folded down over the tank 1 to conserve cold during the cold-accumulating period. In modifications, a cabinet may be positioned over the tank 1 and have doors for insertion of the churns, in which case the cooling heads are not used but the chilled water is used in a surface cooler for the milk. Alternatively, a surface cooler and the cooling heads may be connected in series.

Title: Process for the production of barium hydroxide
Inventor: LEAVES JOHN PHILIP
IPC: B01J47/00
Filed: 1962-04-19
Abstract: Barium hydroxide is prepared by contacting an aqueous solution of a barium compound other than barium sulphide either with a strongly acidic cation exchange resin in the sodium or potassium form, the isolated resin being at least partly regenerated with sodium or potassium hydroxide, e.g. 3-8N, to yield simultaneously barium hydroxide solution, or with a strongly basic anion exchange resin in the hydroxyl form, the barium hydroxide solution being the effluent. A concentrated solution of barium chloride, nitrate or acetate at up to 100 DEG  c. may be passed through a bed of the cation exchange resin in the sodium form, and the resin, after water washing, regenerated by passing excess 4N NaOH in the reverse direction. Barium hydroxide octahydrate crystallizes from the concentrated and cooled regeneration effluent and is washed with cold water.  The mother liquor, after addition of sodium hydroxide, is recycled. Alternatively, barium chloride, nitrate or acetate solution at ambient temperature may be passed through a bed of the anion exchange resin in the hydroxyl form, when barium hydroxide octahydrate crystallizes from the effluent from the resin. Sodium or potassium chloride, nitrate or acetate may be recovered from the effluent from the cation exchange resin.

As shown, the handle 23, which is of the kind having a loop normally lying flush with the attachment plate 10, rests on a shoulder 13 in a recess 12 and has a straight bar 28. The bolt 15, apertured at 17 to accommodate the cam, is guided by a bridgepiece 29, has an offset lug 18 and is shot by a spring 21 mounted on a pin 19 secured to lug 18 and slidable through a fixed lug 20. The cam, which operates against the inner face 27 of lug 18, is integral with the handle and has a surface 25 concentric with, or only slightly eccentric to, the pivot pin 24, so that initial movement of the handle compresses spring 21 not at all, or only slightly. A second cam surface 26 effects retraction of the bolt. Outward movement of the bolt is limited by abutment of cam end 30 against bridge-piece 29 and inward movement by contact of boltface 32 with the surface 31 of the handle.
