Filed: 1966-10-28
Abstract: 1,169,546. Valves. M. GOLDSHOLL. 28 Oct., 1966, No. 48480/66. Heading F2V. [Also in Divisions G3 and H2] An electric supply system for operating an electric motor 20 intermittently comprises a gravity switch 31, 38, which closes after a delay period on being turned through 180 degrees to complete a circuit for energizing the motor 20, which turns the gravity switch, and the system comprises a further switch for maintaining said circuit energized during the 180- degree turn, which further circuit is opened when the 180-degree turn is completed. The further switch comprises a plate 29 rotated by the motor 20 and having a conducting ring 56 engaged by contacts 54, 55 for completing the circuit to the motor 20 from a battery 21, and diametrically opposed contact plates 58 insulated from the ring 56 and engaged by the contact 55 to de-energize the motor 20 after each 180-degree turn of the plate 52. The plates 58 and the ring 56 are connected as shown to the contacts 38 of the gravity switch, so that when the conducting plunger 31 of the latter has fallen to interconnect two contacts 38, the motor circuit is completed. The motor 20 drives a cam 25 (Fig. 4, not shown) for intermittently opening a valve in a dispenser nozzle 18 of an aerosol container 14 for spraying moth preventative or other spray.

Abstract: 1,132,339. Separating liquids. BECK KOLLER & CO. (ENGLAND) Ltd. 16 Nov., 1965 [7 April, 1965], No. 48632/65. Heading B1D. A mixture of two liquids of different densities is supplied to inlet 11 of settling chamber 10, and the lighter liquid overflows a partition 1 to leave by outlet 15, while the heavier liquid leaves by an upwardly extending pipe 4 to a funnel shaped overflow 5. This arrangement maintains the dividing level 6 between the two liquids at a fixed level, dependent on their densities. Overflow 5 may be connected by flexible hoses (18) to permit vertical adjustment between separating different liquid pairs (Fig. 4, not shown). Alternatively overflow 5 could be replaced by an internal baffle (20) and a further overflow 1 in the chamber 10 (Fig. 3, not shown). The chamber 10 may be under increased or reduced pressure, in which case auxiliary heavy liquid collectors (16), Figs. 2, 4, are fitted. Sight windows 7, 8 may be fitted. The initial mixture may comprise water and a liquid agent which is condensed therewith in an entraining agent distillation process applied to remove water from newly prepared polymers.

Filed: 1966-11-09
Abstract: 1,160,707. Rotary-piston internal combustion engines. YANMAR DIESEL ENGINE CO. Ltd. Nov. 9, 1966 [Nov. 10, 1965], No. 50325/66. Heading F1F. A rotary-piston I. C. engine of the kind comprising a housing having a two-lobed epitrochoidal inner surface and end covers secured to its opposite ends and a three-sided piston planetarily rotatable within it to carry out a four -phase combustion cycle, includes besides the usual intake and exhaust ports through the epitrochoidal surface, an auxiliary intake port in either the end covers or the said surface positioned so as not to cause any overlap with respect to the exhaust port and valve means controlling the opening and closing of the main and auxiliary intake ports in response to the opening and closing of the carburetter throttle valve. When the engine is idling with the carburretter throttle valve 13 nearly closed, suction within an auxiliary intake port 11 in a housing end cover is sufficient to permit closure of a spring-loaded valve 23 to close the main intake port 3 and so remove the overlap between it and the exhaust port to prevent the dilution of the air-fuel mixture entering the engine and allow the engine to continue working without misfiring. At high-speed operation of the engine, with the throttle valve in or nearly fully open, suction is insufficient to hold the valve 23 closed. Dilution of the incoming charge by the exhaust gases during the overlap period is then insignificant and does not affect the running of the engine.

Filed: 1975-10-30
Abstract: 1472665 Matrix displays GENERAL ELECTRIC CO Ltd 30 Oct 1975 [10 Dec 1974] 53407/74 Heading G5C A display system comprises an electroluminescent panel with two sets of spaced crossing conductors; means for maintaining voltages of V 1  and V 3  on the conductors of the two sets respectively; means for applying scanning pulses sequentially to the conductors of one set which charge the voltage to V 2  during each address period; and means for applying coincident pulses to selected conductors of the second set to change the voltage to V 4  during the corresponding address period, wherein the luminance of a display region integrated over a panel address cycle is reduced from its value when V 1 =V 3 =V 4 -V 2 /2 by making V 1  and V 3  not equal to V 4  - V 2 /2. This reduces the light produced in half select regions and increases contrast. In a panel with n rows sequentially scanned, an OFF region in a column in which the remaining regions are ON, receives one row half select signal and (n - 1) column half select signals. The minimum integrated luminance of such an OFF region occurs when where V 1  = V 3  = V 1 , preferably V 2  is zero. Since the minimum varies with n it is desirable to scan the set with the fewest conductors.

A single-barrelled automatic shotgun comprises a cartridge magazine disposed in the trigger guard element 3 and continued into the stock and a lifter arranged at the forward end of the magazine. The lifter consists of a first part having two arms 12, 13 (not shown), and a plate 11 pivoted on a positioner 17 which is spring- loaded and mounted in the carcass of the rifle for movement toward the lifter. A second part 24 of the lifter is pivoted about the end of the first part adjacent the magazine and is provided with a part cylindrical seat which supports a cartridge during the lifting operation. Cartridges are introduced into the magazine manually by pivoting the lifter upwardly about its first part pivot, the cartridges being held in the magazine by the lifter in its inactive position. When the rifle has been fired the barrel 1 and breech 2 recoil together and as these return to the holding position a cam of the breech causes the lifter to pivot downwardly whence a cartridge is spring-urged on to the lifter (Fig. 3, not shown). During the last part of its travel on to the lifter the cartridge causes a lever 30 to be released and swing under spring-loading to engage a stud 27 of the second part 24 and urge this part and thus the cartridge upwardly into a position whence it can be introduced into the barrel by the breechblock 29 which is released by the movement of the lever 30.
