Title: Improvements in elevator safety apparatus
IPC: B66B5/04
Filed: 1930-04-11
Abstract: 358,960. Catch gear and like safety retaining mechanism for lifts. WAYGOOD-OTIS, Ltd., 54, Fetter Lane, London. April 11, 1930, No. 11518. Convention date, July 5, 1929. Void [Published under Sect. 91 of the Acts]. [Class 78 (iii).] In safety apparatus for an elevator installation, the cage or the counterweight or both are provided with braking mechanism adapted on operation to bring a separate retarding device into action. Fig. 1 shows an elevator system in which the cage 20 and counterweight 21 are both provided with identical braking mechanism which is operated if they attain an excessive speed. The retarding mechanism, Fig. 2, comprises a plunger 30 mounted on the bottom of the cage or. counterweight and working in a cylinder 36 formed of upper and lower chambers separated by a neck 36<1> through which the piston is a working fit. The lower chamber is filled with oil, which, when the piston is moved downwards, is forced into the upper chamber by way of longitudinal grooves 38 formed on the surface of the piston ; these grooves taper towards the top and finally terminate, so that the piston is always brought to rest after moving through the same distance. The cylinder is mounted slidably on rods 34, and carries resiliently on its lower part braking mechanism adapted to slide along and grip the guide rails 27. An auxiliary rope 96, Figs. 1 and 2, moves with this mechanism and operates a centrifugal governor 97 which, when a predetermined speed is attained, causes jaws 57, 58 to grip the rope. Linked bell cranks 55, 76 on the braking unit are thereby operated, and raise sliding rods 84 having lower inturned portions 91, Fig. 6, which cause rollers 92 to become jammed between cam surfaces 90 and the rails 27, bringing the braking unit and the cylinder to an almost instantaneous stop ; the piston 30 thereupon is forced into the cylinder, and the cage or counterweight is brought gradually to rest. The cylinders terminate at their lower ends in caps 48 adapted to engage bumpers 98, 99 at the bottom of the elevator shaft, so that the retarding devices act as buffers if the cage or counterweight should fall.

Filed: 1927-05-04
Abstract: 281,935. Borsig Ges., A., Gress, K., and Plank, R. May 4, 1927. Cooling fish.-In a plant for freezing fish on board ship by circulation of cooled brine, as described in Specification 269,574, the freezing tanks discharge directly into the brine tanks, the filters being omitted. Tanks 6 symmetrically arranged on either side of the vessel are divided by a sloping partition 7 into an upper compartment 12 in which the fish are treated and a lower compartment 13 in which the brine is cooled by evaporator coils 14. The compartments communicate by a brine valve 11 and a packed door 18 is provided for discharge of fish from the upper compartment. A loading shoot 15 to each tank has a covered opening accessible above the deck, and a brine pump 10 and circulation pipes 9 are employed. The excess of brine overflows through a passage 8 to the tank 13. When the freezing is completed the brine is emptied through the valves 11 and subsequently the fish are discharged through the doors 18. In a modification, the freezing tanks are separate from the brine-cooling tanks and are arranged in pairs back to back, with horizontal or sloping discharge doors at or near the bottom operated from the deck by gearing. The fish are discharged on to a shoot leading to a basket in which they may be washed for the coating with ice, and from this basket they may be discharged through another shoot to the storage space. The freezing-tanks are provided near the top with grids 17, and may have openwork vertical partitions 33, Fig. 5, for keeping the fish from massing together. Specification 144,368 also is referred to.

[Also in Group II] Liquid-solid suspension moving from left to right and rotating about an axis parallel to its direction of movement enters (e.g. from a hydrocyclone 1, Fig. 3), the feed chamber 8 of wet-screening apparatus 14-18 and continues to rotate around the inside of the volute peripheral wall 10, Fig. 4, of the chamber, though prevented from further translational movement by an end wall 9, Fig. 3. The suspension emerges from the chamber through a slot 12 on to the upper end of a screening deck 14 composed of assembled spaced bars running normal to the plane in which the deck is curved. The feed chamber with its axial inlet 7 and peripheral outlet 12 is especially intended for connection to the "starting" end of any of the wet-screening apparatus disclosed in Specifications 791,520, 791,857, 791,858 and 791,859, and is intended to use any rotational kinetic energy the entering liquid may have. In Fig. 2 (not shown), the chamber is very little larger than the inlet 7, and in a modification thereof (not depicted) the screening-apparatus is transposed so that the suspension flows along it in an anti-clockwise direction. The axial flow from the other end of the hydrocylone may be similarly screened. In all cases a pipe may extend through the feed chamber into the hydrocyclone to connect the air core therein to the atmosphere. In Fig. 6, the chamber forms an extension of a cylindrical hydrocyclone and has a slide 30 for adjusting the width of the slot 29. In Figs. 7 and 8 (not shown), the chamber is in the form of a cylinder with a set of tangential outlet pipes feeding on to an imperforate portion at the upper end of the screening deck.
