Title: Hydraulically operated clutch mechanism
IPC: F16D25/12
Filed: 1973-06-04
Abstract: 1484563 Clutch-brake combinations RANSOME HOFFMANN POLLARD Ltd 14 Aug 1974 [4 June 1973] 26603/73 Heading F2L In a clutch-brake combination for a motor vehicle wherein a slave cylinder 4 initially acts through a release mechanism 7, 8, 9 on radial clutch release levers 2 to disengage the clutch and thereafter act through a linkage 14, 17 to engage a brake 13 which brakes a clutch driven shaft 1 to facilitate ratio shift in a following change speed gear, the linkage contains adjusting means 19, 20 which automatically compensate for wear in the clutch. As shown a ring 14 is urged by springs 16 into ratchet toothed engagement 14a with a shoulder 15 of the slave cylinder 4 and the ring 14 has radially projecting pins 20 which engage helical slots 19 in a sleeve 17 carrying brake engaging segments 21. Rotation of the sleeve 17 is prevented by radial projections 29 engaging axial slots 30 in a housing member 27. When pressure liquid is applied to a chamber 5 the slave cylinder 4 moves right to disengage the clutch and additionally moves the ring 14 and sleeve 17 right. When the clutch is fully disengaged further rightward movement of the cylinder 4 clamps a brake disc 11 fast with the driven shaft 10 between the brake segments 21 and a spring loaded back plate 22. On release of pressure from the chamber 5 the cylinder 4 and sleeve 17 move left together to disengage the brake and subsequently to engage the clutch. If wear has occurred in the clutch the projections 29 of the sleeve 17 abut a stop 31 before the cylinder 4 has completed the clutch engaging movement and subsequent further movement of the cylinder 4 causes the pins 20 to move along the helical slots 19, the accompanying rotation of the ring 14 being permitted by the ratchet tooth connection 14a between the ring 14 and cylinder 4. The relative axial positions of the cylinder 4 and sleeve 17 are thus adjusted to compensate for the wear in the clutch. In Fig. 3 (not shown) a sleeve (117) fast with a brake presser plate (121) has a lost motion connection (118, 119) with a sleeve (114) formed internally with ratchet teeth that are engaged by complementary teeth on radial plungers (115) carried by the slave cylinder (104). When wear occurs the sleeve (114) moves axially relative to the slave cylinder (104) to adjust the relative axial positions of the slave cylinder (104) and sleeve (117) to compensate for wear in the clutch.

A multiple mould for use in the production of cylindrical ceramic articles, e.g. incubators, is of hexagonal shape to provide a plurality of cylindrical moulding chambers with a minimum quantity of material to form the mould and is made of material which will be consumed at the firing temperature of the ceramic material. The special application is to insulators used in ceramic seals as described in Specification 659,223, [Group XXXVII. The material of the mould may be a synthetic resin which does not affect the ceramic in any way. The moulding chambers are arranged inside a hexagon in groups of seven, nineteen, thirty-seven &c., Fig. 2 being a plan of a mould with nineteen chambers 11. A metal cap 20 fits the hexagonal mould and has pins 24 in line with the chambers 11. The correct quantity of ceramic material is placed in each chamber 11 and the cap forced downwards over the mould in a press. The pins 24 pierce the ceramic material and pass through holes 16 at the bottom. Some material is forced upwards from the chambers 11 by the entrance of the pins 24 and is shaped to form the tops of the moulded articles by recesses 23 in the cap 20 surrounding the pins. Instead of the cap having pins to make holes in the articles the mould may have core-pins 27, of the same consumable material. The cap has recesses 23 as before in which are deeper recesses 28 to receive the tops of the core pins when the cap is pressed completely over the mould. After the cap has been withdrawn the mould containing the moulded articles is put in a kiln and the ceramic material is fired, during which the mould is consumed.

Abstract: 887,561. Nuclear reactors. UNITED STATES ATOMIC ENERGY COMMISSION. Aug. 11, 1959 [Aug. 18, 1958], No. 27405/59. Class 39(4) A sodium cooled graphite moderated nuclear reactor comprises a core tank, unclad graphite moderator disposed in the tank, a plurality of tubes traversing the tank through the graphite, and fuel elements disposed in the tubes. Referring to Fig. 2, a plurality of tubes 10 extend through central apertures in hexagonal columns of graphite (shown cross-hatched) and are welded at their lower ends into nozzles 30 which extend through the bottom plate 3 into a sodium plenum chamber. The graphite columns are supported from the plate 3 by pedestals 32 surrounding the nozzles 30. The upper ends of tubes 10 are welded to bellows 20 attached at their lower ends to nozzles 24 which are welded to the top plate 2 and extend into the apertures in the graphite. The bellows 20 allow for thermal expansion and are surrounded by shrouds 28 which prevent sudden contact of the high temperature coolant emerging from the tubes with the bellows. The channels in the graphite are lined with thin sleeves 35 of a metal resistant to corrosion by sodium, such as zirconium or its alloys, molybdenum, titanium or stainless steel; these metals may also be used for the tubes 10. Thus any sodium escaping from tubes 10 passes through the passages between tubes 10 and liners 35 to the plenum chamber 33 whence it is pumped out of the core. Stainless steel trays 39 are welded to nozzles 24 to catch any sodium penetrating top plate 2 and prevent it reaching the graphite; the sodium then passes through a drain hole 40 into the space between nozzle 24 and tube 10. Between some adjacent graphite columns channels are provided for control and safety rods; these are lined by tubes 13, 36 of similar construction to tubes 10, 35. A vent line (not shown in Fig. 2) is provided to vent the core to the helium or inert gas atmosphere provided above the upper sodium plenum chamber.
