Title: Improvements in and relating to a method of wholly or partially cutting out the backbone of open carcasses, such as pigs' carcasses, and apparatus for carrying out this method
IPC: A22B5/20
Filed: 1965-10-12
Abstract: 1,108,334. Cutting carcases. SLAGTERIERNES FORSKNINGSINSTITUT. 12 Oct., 1965 [15 Oct., 1964], No. 43149/65. Heading A2U. A method of partially or wholly cutting out the backbone of an open carcase (e.g. pig's carcase) by means of two knives each working along one side of the backbone is characterized in that the backbone is firmly gripped between an internal rail and an external rail of U-shaped cross-section, which with its flanges grips the spinal processes of the backbone. A carcase 13 which has been opened on the back and ventral sides, is conveyed by rail section 1 on to rod 6 of intermittently rotating stand 4 where it is held by holder 14 and the backbone is supported by internal support rail 10. The stand 4 is rotated so that the carcase 13 is opposite the knives 15 which are movable up and down by hydraulic or pneumatic pump 18. The clamping rail 27 of U-shaped cross-section is moved by hydraulic or pneumatic cylinders 30 towards the carcase 13 and grips the backbone. The knives 15 are urged into cutting position by a spring in cylinder 19 and the depth of cut is controlled by roller 26 rolling on rail 27. As the knives 15 are moved down the backbone they are moved in and out and up and down by motor 21 via a pair of eccentrics. The rail 27 has at its bottom end a chisel 32 (Fig. 2, not shown) for severing the backbone. A pair of rollers 33 (Fig. 3, not shown) situated above the knives 15 move down behind the knives to open up the cuts and eventually eject the severed backbone. The rail 10 is preferably U-shaped so that it and rail 27 act as guides for the knives. When the backbone has been cut the knife arrangement is returned to its original position, the stand is rotated, and the carcase is passed to rail section 2.

Abstract: 1326254 Valves RELF RESEARCH Ltd 16 Sept 1970 [19 Sept 1969] 44256/70 Heading F2V A mixing valve includes hot and cold water inlet valves 14, 17 communicating respectively with ports 22, 21 (Fig. 4) in a chamber containing a rotary cylindrical valve member 23. In the closed position of Fig. 4, both ports 22, 21 are sealed by pressure-balanced resilient plugs 30, 31 carried by the valve member. Initial rotation of the valve member progressively aligns slot 38 with port 21 allowing cold water to flow to outlet 43 via passages 39, 40 and mixing chamber 41. Continued rotation then serves to align slot 42 with port 22 allowing hot water to flow to chamber 41. The Venturi effect in passages 40, 44 tends to accommodate pressure differences between the hot and cold water supplies; a similar effect can be obtained with a ring of oblique cold water nozzles entering a central mixing passage to which hot water is admitted axially. Hole 46 in the valve member allows withdrawal of the valve member using a hooked tool. A control knob (2, 3) engages grooves 29 on a collar 28 carrying a radial screw 25 adapted to extend through housing slot 26 into hole 27 in the valve member. The valve assembly has mounting lugs 12 and escutcheon plate (1) support lugs 13. Removable nozzle 7 has outlet holes and depressions 8, 9. Where the hot and cold water supplies are at the same pressure, both flows can enter mixing chamber 41 directly.
