Abstract: 1,025,545. Sealing devices; pipe joints. EUROPEAN ATOMIC ENERGY COMMUNITY (EURATOM). Feb. 28, 1964 [March 1, 1963; March 13, 1963], No. 8394/64. Headings F2B and F2G. In order to prevent a fluid medium on one side of a joint between two relatively movable members from leaking through the space between the members, the fluid medium is caused to solidify in the space by cooling means so as to form a seal between the members, a metallic partition completely surrounding one of the members and having an outline defining at least one undulation, being incorporated in the space between the members to act as a retainer for the medium. In Fig. 1, a shaft 1 immersed in a fluid medium 2 is spaced from a housing 4 by means of a metallic partition 5 welded to the housing at 6 and 7 and formed with internal and external helicoidal surfaces. Coolant, e.g. water, is circulated as indicated by the arrows between the partition and the housing so that solidification of the fluid medium takes place between the shaft and the partition. In another embodiment, Fig. 2 (not shown), a metallic partition 11 of helicoidal profile is welded at 12 and 13 to a movable tube 9 and is in sliding contact with a wall 14 defining with a stationary sheath 10 a jacket 17 for circulation of coolant. In a further embodiment, Fig. 3 (not shown), the partition 18 is received at one extremity only to the tube 9, its other extremity being in sliding contact with the wall 14. In modifications of Fig. 3, the partition has one undulation only and the tube 9 may have a reduced diameter end.

IPC: B60T15/04
Filed: 1949-03-28
Abstract: 670,098. Fluid-actuated valves. CLAYTON DEWANDRE CO., Ltd. March 23, 1950 [March 28, .1949], No. 8400/49. Class 135 [Also in Group XXXIV] A control valve mechanism for the brakes of a tractor-andtrailer vehicle comprises separate valve units for controlling operation of the brake cylinders on the tractor and trailer respectively, these units being of similar construction except that the spring of the trailer brake valve is weaker than that of the tractor brake valve, to ensure that the trailer brakes are operated before those on the tractor. As shown the admission of compressed air from the supply reservoirs to the brake cylinders is controlled by double-beat valves 6, 11, and 6a, 11a respectively, actuated by push-rods 22, 22a carried at the ends of a floating lever 23 whose arms are of equal lengths, and which is mounted on a lever 25 connected to an actuating rod 28. The push-rod 22 for the tractor brake valve unit engages a piston 17 separated by a spring 18 from a second piston 13 which, in turn, is separated from a fixed guide member 19 by a spring 15. The trailer valve unit differs from the tractor valve unit only in the fact that its spring 15a is weaker than the spring 15, with the result that upon actuation of the rod 28 the piston 12a engages the disc valve 11a to seal off from atmosphere the outlet 5 to the trailer brake cylinder and to open the compressed air inlet valve 6a before the tractor brake inlet valve 6 is similarly operated. A breather device 29 puts both sets of brake cylinders into communication with the atmosphere when the system is inoperative. The Provisional Specification describes an arrangement in which the tractor and trailer brake control valve units are of identical construction, the arms of the floating lever 23 being of unequal lengths.

Title: Improvements in and relating to extracting frozen food products
Inventor: HIRAHARA KATSUKI
IPC: A23G9/14
Filed: 1969-02-18
Abstract: 1,236,838. Freezing liquid foods. F.M.C. CORP. 18 Feb., 1969 [23 Feb., 1968], No. 8670/69. Heading F4H. In a system for producing stickless moulded blocks of frozen liquid foods, pins depending from an extractor bar are frozen into the food and are used to lift the blocks from their moulds, one of the pins depending into each mould being of such a shape that its rotation relative to the block releases the latter from the pins. As illustrated, extractor bars B are manually transferred from a sterilizer S to a mould conveyer M so that two pins 13 and 14 depend into each filled mould 10 passing from a filling station F. The pins 13 are fixed and the pins 14 are rotatable. The heads 14a of pins 14 are aligned by shoes 16 at a station A whereafter the pins are frozen into the food in a brine bath 12. After freezing, the moulds are lifted from the tank 12, and at an extractor station E a defrost pot is raised to surround the moulds of one bar and an extractor 57 is simultaneously lowered to latch on to the bar. The pot and extractor are carried by racks engaging opposite sides of the same pinion, Figs. 5 and 15 (not shown). The bar is lifted after defrosting and, together with the depending blocks is moved by a product conveyer C through a dipping station D to a release station R. At the latter station the pin heads 14a engage with slots 20a in heads 20 which are then rotated to release the blocks which fall into a bagger 21. The block release action is as follows. The rotatable pins 14 are provided with shoulders which are of such a form that they exert a camming action on rotation relative to the block to force the latter downwards. The shoulders may be formed by an embossed or intaglio screw thread, Figs. 12 and 14 (not shown), or by inclined notches, Fig. 13 (not shown). During rotation of the pins 14 the blocks are held stationary by the pins 13 which are located in the blocks diagonally opposite the pins 14, Fig. 11 (not shown), so as to lessen the risk of block fracture. The release heads 20 form part of an assembly in which they are rotated by a single rack, Figs. 7-9 (not shown). The release assemblies are such that they may be retracted to allow the provision of stick extractors should the apparatus be required to form stick confections. After the blocks have been released, the extractor bars B are carried by the product conveyer to a return conveyer 22 from which they are manually placed in the sterilizer S. The product conveyer and the mould conveyer are indexed by two pneumatic pistons and cylinders whose pistons are reciprocated by a pneumatic reversing switch, Fig. 15 (not shown). A further pneumatic reversing switch reciprocates pistons operating the extractor and product release racks. The pneumatic switches are in turn operated by rotary electric switches driven by one electric motor.
