Title: Improvements relating to reciprocating pumps for the delivery of mixed liquids
IPC: B67D7/74
Filed: 1937-12-18
Abstract: 503,566. Pumps delivering mixed liquids. BRYCE, Ltd., and GREEN, G. W. A. Dec. 18, 1937, No. 35103. [Class 102 (i)] Apparatus for delivering mixed liquids, particularly for use in chemical processes or with internal -combustion engines, comprises a reciprocating plunger 1 in a cylinder 2 having inlet and outlet ports for one of the liquids, a mixing chamber 14 with an inlet valve 19 for a second liquid and an outlet valve 20 for the mixed liquids, and an automatic delivery valve 5 between the pump and the mixing chamber which serves during its return to its seat, when the pressure in the pump is relieved, as a suction pump for inducing a quantity of the second liquid into the mixing chamber. The plunger and/or delivery valve may be provided with means for varying their effective displacement, for example a helical groove 3 associated with radial ports, so as to control the total output of mixed liquids and /or relative proportions of the two liquids. The outlet valve 20 may constitute the delivery valve for a second mixing chamber provided with an inlet valve for a third liquid and an outlet valve for a secondary mixture, and so on, whereby any number of liquids may be mixed. The delivery valve 5 comprises a cylindrical portion 5c, a portion with longitudinal grooves 5b, and a conical plug 5a which engages a chamfered seat on a reduced portion 4a of a housing 4, outward movement of the valve being controlled by a compression coil spring 7 and being limited by an annular member 6 screwed into an enlarged bore at the end of the housing 4. The inlet and outlet valves 10, 20 act against springs 27, 29 and have conical heads which bear against chamfered seats on annular housing members 21, 22 which are separated by a bell-shaped partition member 18. The latter provides passages 18b, 18c leading from the delivery pipe 13 to an aperture 18a which leads to longitudinal and radial bores 28b 28c in the: stem 28a of a member 28 located within the partition member- 18 and serving as a stop for the valve 19. The plunger 1 and valve 5 first propel into the mixing chamber a predetermined volume of the first liquid, then a less volume of the same liquid is withdrawn and replaced by the second liquid, then a further differential volume of the first liquid is propelled into the mixing chamber. Thereafter the two liquids, in exactly mixed proportions and in volume equal to the total effective displacement volume of the plunger, are propelled through the valve 20.

Title: Improvements in or relating to switching devices
Inventor: MARKOWITZ SEYMOUR
IPC: H03K17/81
Filed: 1962-09-14
Abstract: 968,252. Circuits employing bi-stable magnetic elements. AMPEX CORPORATION. Sept. 14, 1962, No. 35193/62. Heading H3B. A load 16A-16D is selectively energized through a magnetic switch comprising bi-stable cores 30, 40, 50, 60 biased by current in windings 38, 48, 58 and 68, the application of driving current to the two driving windings 32, 34; 42, 44; 52, 54; 62, 64 on any one core causing that core to commence switching and the driving current through one of the driving windings to pass through the associated load, and the cessation of the driving currents causing the bias current to pass to the same load until such time as the switched core is restored to its original magnetic state by the bias action. The bias current is supplied by a source 82 and normally passes to ground through a rectifier 110. To switch a core a drive gate 72 or 74 and a negative gate 78 or 80 is selectively opened by a respective select circuit 86 and 90. Positive current from a source 84 then passes through a pair of drive windings 32, 42 or 52, 62 and a rectifier 100 to ground, and positive current from a source 88 passes through a pair of drive windings 34, 54 or 44, 64 and through the bias windings, the rectifier 110 becoming non-conductive. Only one core has both drive windings energized and commences to switch, thereby inducing a voltage in an associated reset winding 36, 46, 56, 66. This voltage causes a rectifier 92, 94, 96 or 98 associated with the core to become conductive and a rectifier 100 to cut off. The driving current from source 84 then passes through the conductive rectifier to the load which may be a winding of a magnetic core memory. When the driving currents terminate, the bias current commences to switch the core back to its initial state and a voltage of opposite sense is induced in the reset winding. This causes the associated rectifier 102, 104, 106, 108 to become conductive and rectifier 110 to cut off. The bias current then passes through the load until such time as the core reaches its original condition. In large switches the rectifiers 100 and 110 may be omitted so that the bias and driving currents distribute among the many loads.

Title: Chlorinated polymers
Inventor: TAYLOR JOHN HEYWARD
IPC: C08C19/12
Filed: 1962-09-17
Abstract: Chlorinated polyvinyl chloride, polyethylene, polypropylene, polyisoprene and natural rubber substantially free from organic solvents, are isolated from mixtures in which the polymers are associated with carbon tetrachloride by a process in which methanol, ethanol, a propanol or tertiary butanol is added to the mixture as liquid and/or vapour, the carbon tetrachloride is removed as an azeotrope with the alcohol by fractional distillation, and any residual alcohol is subsequently removed from the polymer.  The mixture may also comprise chloroform, e.g. when the polymer has been chlorinated in the presence of chloroform, and this is likewise removed as an azeotrope with the alcohol by fractional distillation. The residual alcohol may be separated by distilling, adding water and distilling, or by filtering and drying the filtrate in a hot air oven.  Examples describe processes using (1-6 and 10) chlorinated polyvinyl chloride, carbon tetrachloride and methanol; (9) chlorinated polyvinyl chloride, carbon tetrachloride and n-propanol; (11) chlorinated polyvinyl chloride, carbon tetrachloride, chloroform and methanol; (12) chlorinated polyvinyl chloride, carbon tetrachloride and tertiary butanol; chlorinated rubber, carbon tetrachloride and (7) methanol and (8) ethanol; and (13) chlorinated polyisoprene, carbon tetrachloride and methanol.
