Title: Improvements in and relating to diaphragm pumps and carburettors
IPC: F02M17/04
Filed: 1963-08-14
Abstract: 981,491. Reciprocating pumps, carburetters. TILLOTSON MANUFACTURING CO. Aug. 14, 1963 [Aug. 20, 1962], No. 32183/63. Headings F1A and FIB. In a liquid pump in which a diaphragm 16, Fig. 4, divides a cavity into a liquid receiving chamber 24 and a pumping chamber 22 which communicates with a varying fluid pressure and flap valves 40, 42 control the flow into and out of the liquid receiving chamber, an elastic medium 66, 70 communicates with the inlet passage 44 or outlet passage 60 or elastic media communicate with both for stabilizing the liquid surges set up by the pumping impulses. Pumping chamber 22 is connected through a passage in nipple 26 to a varying fluid pressure source, e.g. a two-stroke internal combustion engine crankcase, and vibrations of diaphragm 16 cause fuel to be drawn through passages 44, 46 and past valve 40, formed as a flap in diaphragm 16, into chamber 24. Fuel is pumped through passages 52, 54 past valve 42, formed as a flap in diaphragm 16 and through chamber 58 and passage 60. Screwed connection 37 may be attached to a carburetter and the diaphragm 16 may be of synthetic rubber or coated fabric. Chambers 64 and 66 which are in communication with the inlet and outlet passages are filled with air to provide surge chambers. In another embodiment a chamber 64a, Fig. 9, which is vented to atmosphere through passage 78, is closed by a portion of the diaphragm which flexes to cushion liquid surges. In further modifications the surge chambers may be filled with a quantity of open or closed cell porous material or an annular resilient cellular or foamed plastic body is disposed in the surge chamber in direct communication with the inlet passage. The modifications may be applied to the pump outlet passages. In another embodiment, the vented chambers 112, 120, Fig. 14, may be unvented so that liquid surges are cushioned partly by flexure of diaphragm portions 110, 118 and partly by compression of air in chambers 112, 120. In a combination of a fuel pump and a carburetter, crankcase pressure pulses are transmitted to pumping chamber 222, Fig. 17, through passages 227, 226, 225 thus causing flow into sump 252, Fig. 18, through filter 242 chamber 256 and past inlet valve 264 into chamber 224. Fuel is pumped out of chamber through passages 274, 276 past outlet valve 278 and through recess 218, passages 284, 180 and 182 to the carburetter inlet control valve 186. Reduced pressure in the mixing passage 132 transmitted to chamber 160 causing upward flexure of diaphragm 162 which moves lever 200 against the action of spring 202 to open valve 186 admitting fuel into chamber 160 and thence through the main or auxiliary orifice systems 166, 170, 168 into mixing passage 132. Specifications 833,036, 854,216, 854,217 and 854,218 are referred to.

Abstract: 1,099,181. Hydraulic transmissions. PLESSEY-UK Ltd. Nov. 4, 1964 [Aug. 15, 1963], No. 32384/63. Heading F2D. Variable-displacement pumps 6, 7 supply liquid through check valves 9 to parallel connected motors A1-A5, the pump displacements being controlled by servo-pistons 10 subject to the pressure drop in orifices 11 in by-passes having check valves 12 and a pressurizing and off-loading valve 13. When one or more of the motors are driven, the valves 13 maintain a predetermined pressure at the valves 12, but when all the motor selector valves 1 are in their " off " positions a pilot path 15 is established from a drain line 16 to the valve 13 to cause it to establish a connection to a drain line 16A leading to a reservoir so that the pressure at the outlet side of orifices 11 falls to zero. The pressure drops across the orifices are thus increased, and the pistons 10 reduce the pump displacements. The check valves 9 and an accumulator 5 maintain the pressure supplied to the valves 1 at the desired value.

Abstract: 716,417. Coating sand. AKTIEBOLAGET B. A. HJORTH & CO. Dec. 23, 1952 [Sept. 9, 1952], No. 32645/52. Class 64(2) A cooling gas such as air moves inwardly in a spiral in a horizontal plane towards a centre near which foundry sand, after use in casting, is introduced to be cooled, so that the sand particles acquire centrifugal force and therefore move outwardly in a spiral, i.e. in radial counter flow to the air, and are discharged from the periphery of the air current. Sand is fed from a hopper 8 on to a rotating disc 10 from which it is directed by stationary wipers 12 into a ring of funnels 13 to be conducted into a housing 1 and towards a plate 5 therein having a central cooling-air outlet fitted with vanes 7 and .connected by a conduit 6 to a suction pump. Air is drawn by the pump into a tangential inlet of a circular channel 15 of gradually diminishing height on a top wall 4 of the housing and enters the housing 1 through an annular slot 18 in that wall. Above the plate 5 there is inward spiralling'of this air and the falling sand thus acquires centrifugal force which carries it out to an annular gap 20 surrounding the plate 5. It then falls down to a discharge conduit 3 and on to a rotating disc from which it is directed into a shoot 24 by a wiper 23.

Abstract: 1416470 Feeding sheets XEROX CORP 10 July 1973 [11 July 1972] 32863/73 Heading B8R  In an electrostatic copying machine provided with a main pile elevator for copy sheets and an auxiliary pile elevator 101 for copy sheets there is control means for permitting movement of the auxiliary elevator to a sheet feeding position when the main elevator is inoperative and for moving the auxiliary elevator to an inoperative position before the main elevator is activated. When the supply of sheets on the main elevator is exhausted or a predetermined number of copies has been produced from sheets from the main table the machine assumes a non-print mode and a signal is applied to line 108 and after a predetermined time interval a signal is applied to line 118. Bistate means 110 responds to the signal on line 118 and assumes its second state. If the operator then actuates auxiliary elevator switch 107 the bistate means assumes its first state. A signal to illuminate indicator lamp 112 is sent and the auxiliary elevator motor control 106 is activated to cause the motor to raise the elevator until the top of the pile is sensed by limit switch 119. This switch continues to control the elevator to keep the top of the pile at a predetermined level during removal of sheets therefrom. When the auxiliary elevator is empty or when a predetermined number of copies has been made on sheets from the auxiliary elevator a further signal appears on line 108 causing the elevator to be lowered to its inoperative position as determined by detector 120. After a time interval a signal is applied on line 118 and bistate 110 is reset to its second state. The main elevator may now be brought to its operative position by actuation of switch 122.
