Title: Improvements relating to vacuum filters
Inventor: DAWSON DAVID
IPC: B01D33/044
Filed: 1963-11-07
Abstract: 1,080,878. Liquid filters. DAWSON BROS Ltd. D. DAWSON and G. DAWSON. Oct. 26, 1964 [Nov. 7, 1963], No. 43932/63. Heading B1D. Liquid in a tank 3 is filtered by being drawn by a suction pump 19 through a filter cloth M which is in contact with the peripheral part of a drum 1 dipping in the liquid, the drum being rotated intermittently to being a fresh stretch of filter cloth into the filtration position. A curved perforated plate 17 fits around the drum periphery with enough clearance to allow for the filter cloth to pass therebetween, the plate extending unperforated at 17X to the sides of the tank. Liquid is drawn from the inside of the drum through the filter cloth and perforated plate, and is then discharged at 20 for re-use. A tuning device starts and stops a motor 8 which through a gear-box 7, chains, and wheels drives the drum and also a roller 12 which draws the cloth off a roll 14. A device for causing actuation of the drum device in the case of the timing device failure or of excess soilage in the liquid may be provided.

Title: Method of making patterned thermoplastic sheets and a patterned thermoplastic sheet, made by this method
Inventor: BEELIEN CORNELIS WILHELMUS
IPC: B29C48/17
Filed: 1967-09-27
Abstract: 1,147,628. Moulding patterned sheets. C. W. BEELIEN. 27 Sept., 1967, No. 43986/66. Heading BSA. [Also in Division B8] A thermoplastic resin sheet having a sharplyoutlined pattern delineated by areas of different colour is made by joining together parts of one or more intermediate ribbons or sheets having a linear sequence of different colours, e.g. by winding the ribbon on a core 22, Fig. 6, so that successive turns of the material in a heat plasticized condition fuse together, and removing the winding from the core, or by lapping an intermediate heat plasticized sheet, Fig. 7 (not shown), to form a block, and cutting sheets from the block. Fig. 2 shows an extrusion die head equipped to receive three differently coloured thermoplastics 4, 5, 6 which are channelled into ducts 15, 16, 17 in a rotary distributer 11. Ribbons are extruded from slots 18, 19, 20 in stationary die head 25 and a sequence of colours is formed as required in each ribbon by rotation of distributer 11 to bring one or other of ducts 15, 16, 17 into alignment with one or other of slots 18, 19, 20. A modified die head, Fig. 3 (not shown), produces intermediate sheets instead of ribbons. Core 22, Fig. 6, comprises a plurality of endless metallic belts 21 which move the winding off the core. The winding is subsequently cooled and cut to obtain the required patterned sheet. The intermediate ribbon or sheet may be made other than by extrusion, e.g. by fusing together numbers of differently coloured strips (26), Fig. 8 (not shown), and then cutting the product (27) so formed into intermediate sheets (28-30), Fig. 9 (not shown), or ribbons (31).

Title: Adder or priority-determining circuits for computers
IPC: G06F7/50
Filed: 1973-01-28
Abstract: 1468342 Adder and priority circuits HAWKER SIDDELEY DYNAMICS Ltd 5 March 1974 [28 Jan 1973] 44763/72 Heading G4A In a multistage binary parallel adder or priority resolving network each stage includes a complementary metal oxide semi-conductor (CMOS) transmission gate to propagate a signal rapidly to the succeeding stage. Adder.-A three stage complementing adder is shown, Fig. 1. CMOS gate 108 transmits the stage carry input to the carry output when the bit inputs to the stage (x, y) differ and CMOS gate 107 transmits an internally generated carry by the NAND of the bit inputs when these inputs are the same. Further CMOS gates 113, 114 generate SUM from the true and inverse carry inputs to the stage, formed by inverters 14, 15, in accordance with whether the stage bit inputs are the same or different, the equivalence, non- equivalence, and NAND outputs 104-106 being generated by CMOS logic 103 (not described). The Specification states that the carry propagating CMOS gates may be provided to transmit "block carry" signals between blocks in a block carry adder. Priority circuit.-Respective flip-flops produce Q=1 outputs when their request inputs are set. A CMOS gate 108, Fig. 3, in each stage propagates a logic "1" input 109 to the next stage unless Q = 1 in the stage whereupon logic "0" is propagated by CMOS gate 107. Whenever logic "0" is propagated, logic "0" is propagated to all succeeding stages. Each stage output is the AND combination of the propagated input to the stage and the stage Q output so that only the highest priority set request input results in a logic "1" output.

The piston may be downwardly biassed by a spring 16. In use, magnetic valve 22 is opened allowing hard water to enter, raising piston 13 until annular groove 27 is opposite pipe 25 so that water can flow through exchange mass 2 and softened water exit at 24. On closure of valve 22, piston 13 falls displacing the volume of water below it into the brine container 7 and hence displacing an equal volume of brine via pipe 10 into the exchange mass 2, This remains there until valve 22 is opened at the beginning of the next softening cycle when it is washed out via pipes 23, 29 cylinder 12 and outlet pipe 30 until piston 13 rises to the top of the cylinder to close off pipes 29 and 30 and allow flow of softened water to 24. A bypass valve 32 may be provided. The variable volume chamber is preferably housed within container 1 or 7. Reference is also made to retaining piston 13 at its upper position by an electromechanical device and releasing it under the control of a water meter.
