[Class 29] Fish or other foods in packets of tin-plate, cardboard, paper, &c., or in temporary metal containers 44 are passed through tubular conduits 12, of a shape to fit closely against the larger faces of the packets, surrounded by evaporating refrigerant or cooled brine in an outer vessel 10, which is supported by and insulated from an outer casing 29, 30. The ends of the conduits 12 are welded to end walls 11 welded to the wall of the vessel 10, which is supported from the outer casing by bolts 31. Inlet and outlet conduits 32, 33 for the packets register with but are spaced from the open ends of the conduits 12, and are preferably closed by individual drop doors 34, which may be lined with felt. The conduits 12 are shown as rectangular and may be divided by a longitudinal partition 27, Fig. 3, to accommodate different sizes of packets or groups of packets. They are spaced and supported in the vessel 11 by perforated transverse members 19. Liquid refrigerant, e.g. ammonia, is admitted to the vessel 11 through a pipe 22 and the level is maintained above that of conduits 12 by a float valve, the upper part of the float chamber being connected to a passage 26 leading into a separator 23 above the vessel 11, vapour being drawn off at 24. A gauge pipe 28, Fig. 3, may be employed to indicate the level by the frost line thereon. To ensure good contact of the packages, flexible stainless steel liners 37, Fig. 3, may be placed on the main surfaces of the conduits. The fish &c., may be wrapped in paper and the packets 45, Fig. 5, compressed and inserted singly or in groups in a metal border frame 44 over which a U-shaped cover 46 is placed. In the arrangement shown in Fig. 4 a belt conveyer 39 is used and the packets are passed continuously through the freezer. In the first arrangement they may remain some time in the conduits and be ejected by a pusher or by a further charge of packets. The apparatus may also be used for thawing frozen goods by circulation of a warm medium around the conduits.

Title: Improvements in the application of labels or wrappers to bottles or like cylindricalarticles
Inventor: READER ROY
IPC: B65B21/26
Filed: 1956-11-15
Abstract: 879,201. Wrapping and labelling machines. ROSE BROS. (GAINSBOROUGH) Ltd. Feb. 17, 1958 (Nov. 15, 1956], No. 34914/56. Class 73. [Also in Groups XVII and XXX]  Describes a method of and apparatus for applying labels or wrappers around cylindrical articles so as to form an overlapping seam in which cellulosic wrappers are made to adhere to bottles still wet from washing without the use of gum. Bottles are fed intermittently in spaced succession to a station A where the leading edge of a wrapper, advanced in timed relationship, is applied tangentially and is simultaneously pressed on, the bottle being then rotated on its axis to wrap on the wrapper which is treated with water or adhesive to make it adhere. Bottles from a moving slatted conveyer 12 .are arrested by a stop 43 and successively rolled between the periphery of a rotating member 33, and a guide plate 19 on to a transfer member 23. The member 23 has plates shaped to engage and locate the base of the bottle (Figs. 10 and 11, not shown) which rotate on a hub 24 and, in conjunction with bobbins 47, support the bottle and lay it sideways on to a cradle 14 on an intermittently moving conveyer 16. The bobbins 47 are on a moving- chain 48 and a roller on a cam operated arm (Fig. 9, not shown) engages the neck of the bottle to lay it down on them. At A the base and neck of the bottle are gripped by friction discs, 61 and 62 rotated intermittently by a Geneva mechanism (not shown) to wrap on a cellulosic wrapper 86. The wrapper, severed from a web 87, is pressed on to the bottle by a roller 88 on an oscillating arm 89. Its leading edge adheres to the wet surface of the bottle and the other end to suction holes (Fig. 3, not shown) on a drum 81 that rotates simultaneously with the discs 61 and 62 and supports the wrapper around the tapered neck whilst it is being wound on. A rotatable pad 92 wetted by a roller 93 wets the leading edge of the wrapper to join it to the trailing edge. The suction is cut off, the drum 81 withdrawn and the conveyer 16 moves the bottle to station B where pleating fingers 97 pleat the wrapper over the bottle neck. Series of these fingers are each mounted on common shafts 98 to which they are keyed only frictionally so that the geometry of the bottle neck limits their pressure stroke, adjustable stops 113 being provided to position them on their return. Gripper jaws114 having rotary and axial movement grip and twist the end of the wrapper. The wrapped bottle is transferred to a delivery conveyer 18 by a mechanism similar to that which placed it in the cradle 14, but working in the opposite direction.

Title: Process for preparing alkali metal cyanates
IPC: C01C3/00
Filed: 1967-07-28
Abstract: 1,145,777. Alkali metal cyanates. E. I. DU PONT DE NEMOURS & CO. 28 July, 1967 [1 Aug., 1966], No. 34919/67. Heading C1A. Alkali metal cyanates of high purity (98% or more) and having a cyanide content of less than 1 p.p.m. are prepared by heating an alkali metal carbonate and urea in the presence of a heel of the cyanate to be produced which is at least 90%, preferably at least 95% pure and which constitutes at least 35% by weight of the reaction mixture. When preparing sodium cyanate the heel preferably constitutes 45% of the mixture whilst for the production of potassium cyanate it should constitute 55% thereof. The mixture is heated, preferably whilst being subjected to an "intensive rubbing, smearing and mixing action" to a temperature in the range 80 to 225 C. until the evolution of vapours ceases, this normally requiring 4 to 7 hours. The reaction may be carried out either as a batch process or a continuous process, e.g. in a screw conveyer using a portion of recycled product as heel or operating several batch reactions in cascade.

Title: Improvements in or relating to shutter release mechanisms for photographic cameras
IPC: G03B9/58
Filed: 1937-12-17
Abstract: 507,345. Photographic cameras. KODAK, Ltd., and NAGEL, H. Dec. 17, 1937, No. 35038. [Class 98 (i)] In a camera having an externally operated shutter release member adapted to be retracted when the camera is closed, the member is so coupled to a release linkage acting on the shutter trigger that with the camera in a closed or partly closed position the said parts are automatically disconnected to leave the linkage in its normal operative position after the release member has been retracted. As shown in Fig. 1, the release member on the housing 1 comprises a plunger 3 pressed outwards by a spring 16 and pivotally carrying an arm 15 which engages between upturned lugs 7, 8 of a lever 5 of the release linkage. The lever 5 is pivoted at 5a, and a second lever 6 pivoted at 9 to the lever 5 and located above it has an upturned end 10 engaging the shutter trigger 11 and an inner end comprising a plate 12 having a fork 13 engaging a stud 14 on the camera bed. On pressing the plunger 3 to release the shutter, the lever 5 rotates and the arm 10 actuates the trigger 11. On closing the camera, the arm 15 rides on the surface of the plate 12 and so rises above the lugs 7, 8 so that on manually retracting the plunger the arm may be held by a lug 17 on the plate 12. On opening the camera, the plunger is ejected by the spring 16 and the arm passes over an inclined of the lug 8 to lie between the lugs. Specification 484,872 is referred to.

Abstract: 805,043. Vehicles with platforms which lower for loading. SENTINEL (SHREWSBURY). Ltd., and HAMBLIN, L. F. Dec. 4, 1956 [Dec. 7, 1955], No. 35086/55. Class 78 (4). [Also in Group XXXII] All the wheels of a low-loader trailer can be raised relatively to the platform 1 (Fig. 2) so that the platform can be lowered to the ground and the wheels at one end can be swung laterally to leave the end free for loading. In the goose-neck trailer illustrated the rear wheels 2 are carried by yokes 3 pivoted about axles 8 to yokes 9 (see also Fig. 3) which can be pivoted about vertical axes 10 by rams 14. The front wheels 4 are carried by a yoke 15 pivoted at 16 and moved by hydraulic rams 17 the non- working chambers of which are connected by a conduit 28 to the working chambers of rams 11 raising and lowering the rear wheels 2 so that the wheels are moved in unison. Spring-biased catches 19, 23, 24 normally preventing the motions described are released hydraulically. Hydraulic and mechanical interconnections between the rams and the catches may provide for automatic lowering or raising of the wheels once an initiating control has been operated and may also cause the legs 2 to be swung outwardly and a jack-knifing ramp 25 (Fig. 2) to be lowered by rams 26. Additional interlocks may prevent the latches 19, 23 being withdrawn unless there is sufficient pressure in the rams 17, 11 to take the load and may prevent the ramp 25 from being lowered before the wheels 2 have been moved outwardly.

Title: Improvements in or relating to gyroscopes
IPC: G01C19/02
Filed: 1960-10-17
Abstract: 925,441. Gyroscopes. REID & SIGRIST Ltd., and H. C. JARVIS. Oct. 3, 1961 [Oct. 17, 1960], No. 35523/60. Class 97 (3). In a gyroscope in which the rotor 10 is initially started by a gas blast and subsequently continues under its own momentum a caging mechanism 21 is so arranged that it is operated before the drive can be applied to start the rotor. When air under pressure enters at 26 and passes to chamber 27 it depresses a spring- pressed piston 28 carrying plunger 21. The plunger 21 engages a cam surface 22 on gimbal 13 and, when centralized, passes therethrough to engage cam surface 23 on gimbal 12. The air under pressure can now depress hollow plunger 18 into engagement with inlet 17 and pass therethrough to the rotor driving nozzles. To allow for manual operation, a screw 25 may be removed so that a tool may engage and depress the piston 28, which is held by a spring- pressed latch 35 releasable by pulling on knob 37. If air pressure is applied when the gimbals are already caged, air flowing through passage 38 first releases latch 35 and then holds it released so that when the air pressure is cut off the plunger 21 is retracted by its spring 29. Electrical contacts may provide remote indication of the position of plunger 21.
