Title: Improvements in liquid fuel supply systems for internal combustion engines
IPC: F02B1/00
Filed: 1926-12-31
Abstract: 286,821. Royce, F. H. Dec. 31, 1926. Actuating by gas pressure ; regulating delivery by opening suction valves; suction reservoirs.- In an internal-combustion engine, fuel is raised from the main tank to an elevated supplemental tank adapted to supply the carburettor float chamber by gravity, by a plunger pump immersed in the fuel in the supplemental tank and operated by the engine, e.g. by an eccentric on an enginedriven shaft and intervening rods and levers, or by subjecting a piston connected to the pump plunger alternately to atmospheric pressure and to the suction in the induction pipe, means being provided for limiting the depth of fuel in the supplemental tank. As shown in Fig. 1, the supplemental tank a is respectively connected to the main tank and the float chamber by conduits a<2>, a<3>, and is provided with a partitioned off part a<1> containing the pump b, the plunger b<1> of which is reciprocated by an eccentric c<1> through a spring-loaded push rod c', a lever c' and a rod c<8>. The eccentric c<1> is mounted on a shaft c driven at a low speed from the engine. To limit the depth of fuel in the tank a, a float d is provided adapted to operate a lever d<3> and open the delivery valve, b<4> of the pump when the fuel reaches a predetermined level. As shown in Fig. 2, the plunger f<1> of the pump f is connected to a piston g<1> bv a rod g<5> loaded bv a spring g' and provided with collars g<6>, g<7>. The space above the piston g<1> is connected by a conduit h, chambers h<1>, h<9>, and a conduit h<2> to the induction pipe, and the space below the piston g<1> is open to the atmosphere through an aperture g<11>. The chamber h<1> is subjected alternately to atmospheric pressure and to suction by a double valve l operated by a toggle mechanism k<2>, i, and adapted to close alternately the openings at the top and bottom of the chamber h<1>. The toggle mechanism comprises a rod k<2> sliding in a pivoted block k and pivoted at k<4> to a lever i carrying the valve l and mounted on a pivot i<1>. The lever i is provided with pins i<4> adapted to be engaged by the end of a lever also mounted on the pivot i' and provided with jaws j<1> embracing the rod g<5>. When the piston g<1>, and hence the pump plunger f<1>, is raised by the suction transmitted from the induction pipe, the lever i is rotated by the engagement of the collar g<6> with the jaws j<1> and the toggle mechanism is actuated by the engagement of the end of the lever j with the pins i<4>, thus operating the valve l to cut off the suction and open the chamber h<1> to the atmosphere. The piston g<1> and plump plunger are then retracted by the spring g<9>, the lever j is actuated by the collar g<7> to reverse the movement of the valve l, and the chamber h<1> is again subjected to suction. When the fuel reaches the predetermined level in the tank, the lifting of a float m operates a valve m<6> to cut off the chamber h<1> from the suction in the induction pipe.

Title: Word organized random access memory systems
IPC: G06T1/60
Filed: 1975-08-08
Abstract: 1504713 Accessing random access memories INTERNATIONAL BUSINESS MACHINES CORP 8 Aug 1975 [7 Nov 1974] 33130/75 Addition to 1504602 Heading G4A The word organized random access memory system of the parent application is further modified so that the pq image points of 1 x pq or pq x 1 or a restricted number of p x q sub-arrays can be accessed in a single memory cycle, one image point being stored in each of pq memory modules each with rs cells. Each image point I(i, j) of a pq x rs arrays is assigned to a module M(i, j) given by the expression M(i, j) = [iq + (i/p)//q + j]//pq at an address A(i, j) = (i/p)s + j/q where // and / respectively represent the remainder and integer quotient of the division. In this modification only p x q sub-arrays whose reference, e.g. upper left hand, image point falls on the ith row of the image array (i being a multiple of p) can be stored. The address generation logic is similar to that of the parent Specification, the shape of the sub-array being represented by a 2-bit parameter t instead of a single bit. The permuters for transferring bits between the pq-bit data regiser (39) and the memory modules are also modified by the inclusion of a special permuter, Figs. 11, 13 (not shown), which, for a pq x 1 sub-assay distributes successive bits of an input word to every pth bit of the output word (mod pq).

Title: Improvements in Electrolytic Material Removal Method.
Inventor: ANDREWS J
IPC: B23H9/16
Filed: 1966-07-22
Abstract: 1,159,092. Electrolytically producing holes or cavities. GENERAL ELECTRIC CO. July 22, 1966 [July 26, 1965], No.33162/66. Heading C7B. A method of electrolytically producing holes or cavities in an electrically conductive workpiece comprises the steps of placing a tool comprising a nozzle made of dielectric material opposite to but spaced from the workpiece, passing liquid electrolyte through the nozzle to form a jet directed on to the workpiece, causing the jet to be electrically charged by applying a direct or alternating voltage between the workpiece and an electrode immersed in the electrolyte flow upstream of said nozzle, and maintaining the voltage at a level sufficiently high to maintain a condition at or beyond the threshold of glow discharge at the region of the workpiece upon which the jet of the electrolyte impinges, said level not being so high as to permit sparking to occur directly between the electrode and the workpiece. At the threshold of glow discharge an increase in applied voltage produces a reduction in current. The material removal may be at 300 to 1200 volts with a current of up to 4 amps. Holes as small as 0À001 inch in diameter may be formed using electrolyte nozzles, e.g. of 0À0007 inch internal diameter. Fig. 1 illustrates the removal of material from a workpiece 20 using a jet of electrolyte 23 from a nozzle 26, e.g. of glass, containing a conductive tube electrode, e.g. of Ni base alloy Figs.2 to 6 (not shown) illustrate the formation of a hole right through a workpiece. The nozzle is fed towards the workpiece at a relatively fast rate, then at a slower cutting rate until break through occurs, and then at a somewhat slower rate. The tool is then retracted. By appropriate selection of the initial feedrate, the shape of the cavity mouth and cavity walls can be controlled. Control of the different feedrates may be by an operator watching an ammeter or by an automatic programme control (52, Fig. 7 not shown). Programming can be by conventional electrical mechanical or electronic devices which respond to current sensing means. The feedrate may exceed the rate at which material is removed from the workpiece. Workpiece holder (40) is a three-dimensionally adjustable indexing table. The workpiece may be a tube or plate. In another method of working, the nozzle need not be fed towards the workpiece. Examples 1 to 12 are of working Ni and Ni base alloys using HCl and H 2  SO 4  electrolytes. The workpiece material and electrolytes used in Examples 13 to 19 are as follows:- (13) Fe base alloy, HCl (14) Ni " " H 2 SO 4  (15) Ag " " HCl (16) Carbide HCl (17) Zr base alloy, HCl (18) Cu " " H 2 SO 4  (19) Co " " " H 2 SO 4  The detailed compositions of the alloys are given.

Abstract: 849,371. Moulding filled chocolates. WINKLER, R., and DUNNEBIER, K. Oct. 28, 1957 [Dec. 29, 1956 ; May 24, 1957], No. 33513/57. Class 87(2). [Also in Group VI] Filled chocolates, e.g. chocolate creams or liqueurs, are formed by forcing chocolate from a hopper 1, having an agitator 2, by means of a piston 4, through a valve 5 and passage 16 to a double nozzle 18, and forcing the filling from a hopper 8, by means of a plunger 10, through a valve 11 and passage 16<SP>1</SP> to the double nozzle. The amplitudes of the piston strokes and the time at which one piston is operated relatively to the other may be adjusted during operation. The amplitudes of the piston strokes are adjusted by wheels 150, 150<SP>1</SP>, Fig. 11, which alter the distance between a sliding member 145 and the fulcrum 143 of a lever 142 which operates the piston 105 through a linkage 152, 154, 156, 110. The timing of the piston 105 is controlled by a wheel 136 (co-operating with a scale 137) which adjusts a differential gear 131 driving the cam 135 connected to the lever 142. The hoppers are heated independently by hot water jackets. The chocolate and filling are deposited into preheated moulds 20. After filling, the moulds may be tapped, cooled, turned and the finished chocolates extracted. In a modification as shown in Fig. 11, the materials in the hoppers 102, 103 are forced through the nozzle 108 by pistons 104, 105. The nozzle 18 is easily removable to allow it to be changed.
