IPC: F04D9/04
Abstract: 1, 095, 314. Centrifugal pumps; hand vacuum pumps. W. MURRAY and U.M.W. BARSKE. Sept. 30, 1964 [July 4, 1963], No. 26627/63. Headings F1C and F1N. During priming of a suction-lift pump 8, Fig. 2, such as a centrifugal pump, a valve 10 is closed and air is extracted from the lift pump by a positive displacement pump 14 and delivered into the delivery line 5. When priming has been effected the lift pump is operated and the valve opened. The pump 8 and priming system may be carried on a trolley and used to pump liquid fuel from an underground storage tank to a mobile tanker. A vacuum gauge 12 indicates when priming is completed. The pump 14 is preferably a reciprocating piston pump manually operable as by a handle, and has an inlet valve 17, 18, Fig. 4, and an outlet valve 21, 23 in its cylinder head. The balls 17, 21 may be of stainless steel and the seats 18, 23 of p.t.f.e. or glass. The balls may be spring-loaded and are surrounded by cages formed by diametral slots at the bottom of inserts 24, 25 which may be of plastics material. When the pump is inoperative, a wing nut 33 is slackened to permit a spring 32 to force a rod 28 on to the ball 17 thereby forcibly closing the inlet valve and preventing liquid in the system from entering the pump. An insert 29 of plastics material may be provided at the bottom of rod 28. The pump may be generally constructed of synthetic plastics material to avoid corrosion.

Abstract: 1,227,114. Temperature responsive actuating elements. INTERNATIONAL CONTROLS CORP. Feb.4, 1969 [Aug.19, 1968], No.5869/69. Heading G1D. [Also in Division F2] A thermal motor, which is suitable for use in operating a valve, comprises a cylindrical chamber 12, a piston 14 composed of two piston portions 16 and 18, which piston portions define therebetween a shoulder 20 and extend through the cylinder end walls, and a heating element 22 which is designed to activate a thermally responsive material, such as wax, contained within the chamber. With the above arrangement, and upon heating of the material, the resultant expansion acts on the shoulder 20 and so tends to displace the piston and cylindrical chamber relative to one another. When contained in a valve, Figs. 2 to 5, (not shown), wherein the flow passages may be aligned or at right angles to each other, either one of the portions of piston 14 is anchored to the valve body and the cylinder carries the valve member, with the cylinder being subjected to the bias of a spring acting in a direction tending to close the valve.

The compounds may be obtained by reacting a polyimine with a chlorosubstituted silicon compound of formula Cl-R'-Si#; by reacting a polyimine with an organosilicon compound containing an oxirane. ring to produce a compound in which R' contains a hydroxyl group: or by adding a polyimine to the double bond of a silicon compound containing a vinyl group. The starting silicon compound may be a polysiloxane. When the compounds of the invention contain silane groups they may be hydrolysed to siloxanes. The compounds of the invention may be used to prime siliceous and metal surfaces to improve the adhesion of synthetic resins. They may be applied to the surface ready prepared or prepared on the surface. In Examples compounds of the invention are applied to glass slides, which are then coated with polypropylene and polyethylene, and are coated on glass fibres which are mixed with nylon and moulded.

Abstract: 1,234,096. Measuring speed electrically. WESTINGHOUSE AIR BRAKE CO. July 31, 1968 [Aug.11, 1967], No.36440/68. Heading G1N. [Also in Division H3] A fail-safe switching circuit (see Division H3) is used to detect when a vehicle when a vehicle speed exceeds a prescribed speed command for a given area. A generator coupled to the axle produces an A. C. signal having a frequency which increases with speed. This is applied to a limiter and low pass filter circuit to a threshold metal so that if the speed exceeds the valve corresponding to the cut-off frequency of the filter the output falls to a low value and the switch circuit is released. This may operate a warning device. The threshold circuit, for fail-safe reasons, uses an electrooptical threshold device and generates signals which are of opposite polarity to the supply voltages so that false signals are not produced by component failure.

Abstract: 1,258,913. Checking public transport passengers. COUNTY BOROUGH OF BRIGHTON. 31 Oct., 1969 [5 Aug., 1968], No. 37291/68. Heading G4T. A device for indicating when the number of passengers on board a public transport vehicle exceeds the number of unexpired fares comprises a passenger counter adapted to register the number of people on board the vehicle at any time, a fares counter adapted to register the individual totals of people whose fares expire at each of a number of fare stages, a total fares counter adapted to register the total number of fares, a control device operable to cause the total registered by the total fares counter to be reduced by the number associated with each individual fare stage in turn, and means enabling the totals stored in the passenger and total fares counters to be compared. As shown, operation of a ticket machine T or a reading device R causes G to generate a pulse which a distributer DS directs to one of a number of sections CF1-CFn of the fares counter CF. The distributer selects the particular section in dependence upon the position of the stage switch S, which is operated either manually or automatically when the vehicle passes each fare stage, and in dependence upon the denomination of the fare. The number recorded in each counter CF r  is the number of passengers who have paid for travel to fare stage r. When the vehicle reaches fare stage r, operation of S clears CF r  and subtracts its total from the total fares counter CT. The totals in CT and the passenger counter CP may be compared by device E (a lamp may be energized if CP's total exceeds that of CT) or the totals may be displayed for comparison. The passenger detector D operating CP may be in the form of a turnstile, a photosensitive device or pressure pads in the vehicle stairs, Fig. 4 (not shown). The whole device may be electro-mechanical, Fig. 2 (not shown). In an alternative and electronically operated embodiment, Fig. 3 (not shown), each section CF r  of the fares counter is adapted to record the number of rth denomination fares paid. At each operation of the stage switch, the total in each CF r  is transferred to CF r-1  and the total in the lowest order CF section is subtracted from the total fares counter.

A plug 5 seals one end of the cigarette and the other end is connected by a tube 6 to a suction system. The chamber 25 may be vented to atmosphere thro a valve 27 and is also connected to a shut off valve 13 and suction chamber 19. The inner chamber 2 is connected to a vacuum pump 12, and transducers 7, 8 connected to a meter 9 measure the applied suctions. In operation the valve 27 is closed by a compressed air cylinder 23 and the suction valve 13 is opened so that the rubber tube 24 may be expanded to accept a cigarette. The plug 5 and the tube 6 are then positioned and the valves 13 and 22 closed so that the port 26 is again opened to atmosphere and the tube 24 allowed to contract around the cigarette. The valve 11 is now opened to apply a small amount of suction to the chamber 2 so that the pressure drop detected by the air-flow thro the gap between the tube 24 via the ring 4 may be measured by the transducer 7 and be related to the initial or unloaded diameter of the cigarette. Suction is now applied via valve 14 to the tube 6 and the inside of the cigarette so that a pressure load is applied to the outside of the cigarette by the air passing into the chamber 25 thro port 26. The transducer 7 is read again to give a first loading diameter and the transducer 8 is read to give the pressure at that diameter. A second diameter and a second pressure reading are obtained by closing the valve 14 and opening the valve 15 connected to a greater suction pressure chamber 21. From the various diameters and pressures obtained a hardness figure may be obtained from a stated formula and the pressure initially exerted by the tobacco on the paper wall may also be computed.
