Abstract: 1,158,929. Filtering coolant liquid. F. J. POPELAR. 14 Nov., 1966 [22 Nov., 1965], No.. 50855/66. Heading BID. Contaminated liquid coolant from a machine tool 16 passes through gravity settling chamber 32 and is then drawn into a filter through screen 130 by a pump 46. The coolant passes through cylindrical filter element 108 where about 2/3rds of the coolant filters through the element 108 and the rest passes on carrying separated solid with it past adjustable restriction 114' into pipe 116 and round perforated bend 120 where solids pass through the perforations 126 due to centrifugal force, and the coolant is recycled through pump 46. Wedge shape scrubbing pieces 140 may be included in the recycled fluid flow. Filtered coolant together with any unfiltered fluid from pressure relief valve 138 is delivered to machine tool 16 by pipe 68. In Fig. 1 not shown cylindrical filter elements (60) are arranged in parallel and solids settling in the reservoir are removed by blades (77) attached to chains 76. The filter elements (60) may comprise resin bonded cellulose fibres which become more dense towards the centre of the element, or, Fig. 4 and 5, may comprise a fine mesh stainless steel screen 208 attached to a central support 210.

Abstract: 1414656 Cleaning ultrafiltration cells DORROLIVER Inc 15 Nov 1972 [15 June 1972] 52808/72 Headings B1D and B1X Ultrafiltration or reverse-osmosis cells comprising an open ended channel for material to be filtered separated by a membrane from a filtrate channel are cleaned by removal of deposited material from the upstream side of the membrane by (a) purging the material to be filtered from its respective channel; (b) replacing it with a cleaning fluid, e.g. filtrate: (c) sealing the filtrate channel to prevent flow therefrom and equalise the pressures on each side of the membrane; and (d) flushing the cleaning fluid through the channel to mechanically remove the deposited material. The ultrafiltration cell described comprises a housing 12 (Fig. 1) containing a number of ultrafiltration cartridges 14 each formed by a plurality of parallel membrane-coated panels 26 of hollow box form (Fig. 1a not shown) defining therebetween a number of openended channels for material to be filtered and extending from inlet 18 to outlet 22. Filtrate collects in the interior of each hollow box and is led out in a direction normal to the feed flow through an aperture 19 in each cartridge and then by way of connecting pipes 17 to filtrate outlet 24. Taps 27 are provided on each pipe 17 for closing the filtrate channels: Flushing of the feed channels may be effected in the same direction as feed flow or in the opposite direction. The described ultrafiltration process is the treatment of electrophoretic paint compositions using a system (Fig. 2 not shown) using a plurality of ultrafiltration cells each of which may be flushed separately whilst filtration is continuing in the other cells. In such a process the membrane may suitably have an average pore size of 20-100A and the cleaning fluid may comprise soap, a detergent, an enzyme, or a mixture of a ketone and a detergent in aqueous sodium carbonate or triethylamine.

Abstract: 1366610 Friction clutches DAIKIN SEISAKUSHO KK 17 Nov 1972 [18 Jan 1972] 53258/72 Heading F2C In a friction clutch wherein a driven disc 10 is normally clamped between a driving flywheel 1 and a presser plate 5 by a diaphragm spring 7, ducts 15 through the flywheel 1 deliver cooling air to the space between the flywheel 1 and driven disc friction facing 11 during clutch disengagement. Fins 16 on the flywheel 1 direct air towards the ducts 15. The ducts 15 may be parallel to the clutch axis or may be inclined to the axis. During clutch disengagement the air pressure acting on the driven disc 10 moves the latter away from the flywheel 1.

Title: Bolt firing device for cattle slaughtering
IPC: A22B3/02
Filed: 1972-11-21
Abstract: 1416189 Animal slaughtering device K H KERNER 21 Nov 1972 [21 Dec 1971] 53747/72 Heading A1M A slaughtering gun contains a captive bolt consisting of a shaft and piston arrangement 9 within a barrel 1 fastened to a cartridge chamber 2 and a guide 3. Gases from the fired cartridge pass through an inlet duct 14 in the piston and valve ducts 18 into a compression space 19 while propelling the shaft 11 through the guide 3 to penetrate the animal's skull. The acceleration of the shaft and piston results in sealing the inlet duct 14 by a ball 17 which is seated on a valve seat 16 by its inertia so that on losing forward momentum the shaft and piston 9 is returned to its initial position by the gases trapped in the compression space 19 sealed by sealing ring 20 and a gland ring 25. As the piston 10 is returned the expanding gases are relieved to atmosphere by an outlet duct 21 which connects to an annular space 6, formed between a sleeve grip 5 and the barrel 1, and then through an outlet duct 22. When the piston and shaft return to the starting position any residual pressure remaining in the compression space 19 is relieved by a duct 27. Increased pressure in the compression space 19 increases sealing action through a support ring 24 bearing on the gland ring 25 which also forms a resilient stop if pressure fails to develop in the compression space 19 due to malfunction. The calibre bore in cartridge chamber 2 tapers conically towards the piston 10.

The projectile 11 comprises a cylindrical rubber member which is forced into a housing 1 of the launcher, has a hemisphericalshaped head 17, Fig. 8, and has rims 14, 15. The base 2, Fig. 2, has a plate 16 which protects the projectile from pressurized gas or bullets; or, alternatively, the rubber is suitably hardened. The socket 4 has a conical-shaped rim 5, Fig. 3, and a rib 6. The connecting ring 8 is made of frangible synthetic plastics material, is forced on to the muzzle 7 of the firearm, is provided with an inner rib 9 which engages the rib 6 of the socket 4, has a ridge 10 and is slotted at 12, 13, Figs. 2 and 4. When the weapon is fired the projectile is propelled forward as shown in Fig. 8 and the launcher is forced rearward thus causing the rim 5 of the socket 4 and the ridge 10 of the ring 8 to collide and break the latter. When the projectile 11 has left the housing 1 pressurized gas from the muzzle 7 ejects the launcher. In modification the socket 4, Fig. 10, has an outer rib 19 and the connecting ring 8 is provided with a conical portion 18.
