Abstract: 1,064,396. Diaphragm compressors. GEORGE KENT Ltd. Dec.6, 1965 [Dec. 8, 1964], No.49986/64. Heading F1N. A double-acting diaphragm pump comprising a cylinder (6) Fig. 2 (not shown) divided by a spring-biased diaphragm (7) into chambers (5, 8) is arranged in parallel with a gas meter (1) and a two-way valve (4) which latter is mechanically linked by a lost motion connection to the diaphragm (7) whereby when the latter has been moved slowly to one end position by the action of supply pressure in chamber (8) and acting against diaphragm spring (10) thereby displacing gas from chamber (5) into a point in the meter line downstream of the closed valve (4) the valve (4) is snapped open and gas in chamber (8) is forced through the meter by rapid displacement of the diaphragm by its spring (10) assisted by gas pressure downstream of the meter to its other end position in which the valve (4) is re-closed with snap action. Gas is thus passed through the meter (4) in gulps whereby small flow rates are registered. During normal flow rates gas pressure in chamber (8) so exceeds that in chamber (5) that valve (4) is maintained open.

Title: Improvements in or relating to automatic telecommunication systems
Inventor: BARTLETT WILLIAM FREDERICK
IPC: H04Q11/04
Filed: 1963-12-31
Abstract: 1,076,780. Automatic exchange systems. GENERAL DYNAMICS CORPORATION. Dec. 31, 1963, No. 51354/63. Heading H4K. In a time division exchange, means are provided for diverting calls intended for certain subscribers (transferors) to predetermined other subscribers (transferees). A subscriber, e.g. station 1 requiring this facility lifts his receiver whereby a free time slot (4) is allotted to him, and then he dials a special code digit, e.g. 6. The identity of the transferor and the special digit are stored in compartments, corresponding to the allotted time slot, of a calling line store 12 and a terminating line store 6313 respectively (step 1). The number of the time slot is then marked in a delay line transfer store TS4 and the code is deleted from 6313 (step 2). The transferor dials the number of the transferee (station 3) into the terminating store (step 3) and hangs up. If now another subscriber, e.g. station 2 calls station 1, their respective identities are stored in compartments of stores 12 and 6313 during a time slot, e.g. 5 allotted to the new call (step 4). A line number counter 123 successively provides at its output, for a space of two time frames, the identity of every subscriber in the system. When this output next identifies station 1 therefore, two comparators which are connected to stores 12 and 6313 respectively, provide output signals whereby the number of the time slots, e.g. 4 and 5, containing this identity are passed to a second transfer store TS45 and the identity of station 1 is deleted from time slot 5 of store 6313 (step 5). When the output of counter 123 identifies station 3 (step 6) then, during the first time frame of this output signal, suitable apparatus is set, whereby during the second time frame (step 7) the identity of station 3 is written into the compartment corresponding to time slot 5 of store 6313 and the contents of transfer store TS45 are erased. Station 2 is then connected to station 3 in the usual manner. When both parties hang up, the information in time slots 5 of stores 12 and 6313 is removed (step 8). The information in store TS4 and in time slots 4 of stores 12 and 6313 is deleted only when station 1 dials another suitable code digit. The transferor may initiate diversion of his calls by dialling his own number in place of the special code digit. The transfer store TS45 can only be used for diverting one call at a time, i.e. any call which requires diverting and which is initiated during steps 5 to 7 must either be released or must await release of store TS45.

Abstract: 1,096,678. Multiple effect distillation apparatus; desalination of water. PACTIDE CORPORATION. Nov. 18, 1966 [Nov. 26, 1965; May 26, 1966], No. 51715/66. Addition to 1,096,677. Heading B1B. A multiple effect distillation apparatus comprises porous membranes 10, which are permeable to the vapour of the liquid being distilled but impermeable to the liquid itself, arranged in alternate stacked relationship with corrugated heat-conductive barriers 12, which are impermeable to both liquid and vapour. The liquid to be distilled, e.g. salt water, flows through the channels formed by the underside of each porous member 10 and the upper surface of the adjacent corrugated barrier 12, the flow being in the direction of the corrugations. Distillate liquid, potable water, flows through the other channels. A gasket 26, in the form of a frame, is disposed between each porous member and the adjacent barrier; and the whole assembly is clamped between header plates. The lower header plate 16 is supplied with heat, e.g. by solar energy; and partial vaporization of the distilland in the lowermost channel takes place, the vapour diffusing through the porous membrane and condensing in the distillate liquid flowing through the channel above. The heat of condensation is given up through the heat-conductive barrier to the distilland in the third channel, this multiple-effect operation being repeated in the remaining channels. The upper header plate 14 is cooled, e.g. by feed liquid. The feed liquid is supplied to channel 46 in manifold 40, from which the feed flows through alternate channels of the still, the unevaporated liquid being collected in and discharged from manifold 42. The distillate liquid flows in the opposite direction through the other channels, and is withdrawn through channel 48 in manifold 40. The heat-conductive barriers 12 may be made of copper, aluminium, polyvinylidene fluoride, or a polycarbonate. The porous membranes 10 may be made of polyvinyl chloride, a cellulose derivative, nylon, or polytetrafluorethylene.
