Patent GB-1077560-A (GB)
Title: Diesel fuel
IPC: F02B3/06
Filed: 1965-03-03
Abstract: A diesel fuel contains 0.01 to 5% by weight of an oil-soluble, basic metal composition prepared by carbonating, at at least 50 DEG  C., a mixture comprising (A) either an alkylated phenol having at least 6 aliphatic carbon atoms, or a mixture of a phenol and a polar substance having at least 12 carbon atoms and which is an aliphatic acid ester, an alcohol, a sulphoxide, an amine or an amine-aldehyde condensation product, and (B) at least one equivalent per equivalent of (A) of an alkali metal or alkaline earth metal oxide or hydroxide. Numerous examples of the constituents of component (A) are listed. The alkylated phenols or phenols may comprise bis-phenols and naphthols; the alcohols may comprise Oxo and sperm alcohols and the amines may be partially acylated and hydroxyalkylated with, e.g., ethylene oxide.  Carbon dioxide is passed into the mixed components, preferably suspended or dissolved in a diluent, e.g. hydrocarbons, chlorinated hydrocarbons or mineral oil, the reaction temperature being sufficient to eliminate water in those cases where it forms part of the mixture to be carbonated.  The reaction product, filtered if required, may be added to the diesel fuel, optionally as a concentrate in a solvent such as xylene.  It prevents sludge and varnish formation and renders the fuel more readily combustible.  The fuel may contain colour stabilizers, anti-oxidants, rust inhibitors, dispersants &c., e.g. barium didodecylbenzene sulphonate, the calcium salt of the acidic hydrolysis product of polyisobutene, phosphorus pentasulphide, magnesium mahogany sulphonate, tertiary dodecylamine and the imidazoline obtained by the reaction of oleic acid with diethylene triamine or triethylene tetramine.

Patent GB-1387015-A (GB)
Title: Digital filters
IPC: G06F7/52
Filed: 1972-02-29
Abstract: 1387015 Active filters WESTERN ELECTRIC CO Inc 29 Feb 1972 [4 March 1971] 9269/72 Addition to 1380317 Heading H3U In a digital filter, the logic circuit functions are performed by threshold logic circuits which include storage-processor elements of the type described in Specification 1,380,317. An input sample code word A2 in two's-complement representation is applied from unit 21 to one input of a threshold logic adder 40, and a sample code word A1, resulting from processing prior samples is applied to the other input. The bits of the resulting sum code word S 2  are applied serially to a shift register delay 42 which includes enough stages to store all bits of one sum code word plus three more. The sign bit is also stored in sign store 43. The delayed output is applied to two's-complementing circuit 46 for conversion to sign-magnitude representation, and then to another shift register 47 to give a further delay sufficient to allow the filter to process a second, time-multiplexed input 48 concurrently with input 21. The output from shift register 47 and a predetermined coefficient b 1  from store 50 are multiplied together in multiplex 52, and the resulting output M1 is applied to two's-complementing circuit 53 which converts it under the control of a product sign bit SGNP 1 . This sign bit is derived by adding sign bit SGN 1, previously stored in store 43, and a sign bit SGN b 1  of coefficient b. The output B1 from circuit 53 is fed as one input to adder 55, whose output provides the S1 input to adder 40. The signal from register 47 is also fed via a further shift register and multiplier to a two's-complement circuit 56 which provides the second input A1 to adder 55. The signal S2 is also fed to adder 57 where it is combined with a signal S3 derived from two right hand loops, similar to those on the left. The overflow detection circuit 200 detects positive and negative overflows that occur in adders 40, 55 and multiplier 52. Another overflow detector 300 may be included in the feed forward path. The storage-processor elements which form the major processing circuits of the loops comprise transistor bi-stable circuits (68, 69) with associated charge storage elements (81, 82) Fig. 2 (not shown). The inputs and outputs of several such elements may be selectively interconnected to form an adder, Fig. 7 (not shown), a shift register, Fig. 8 (not shown), a two's-complement, Figs. 9, 10, 11 or 12 (not shown), a multiplier, Fig. 13 (not shown) and an overflow Fig. 14 (not shown).

Abstract: 984,313. Hydraulic reciprocating pumps and motors. COUNCIL FOR SCIENTIFIC & INDUSTRIAL RESEARCH. Feb. 28, 1963 [March 9, 1962; March 13, 1962], Nos. 9279/62 and 9533/62. Heading F1A. An hydraulic pump or motor, especially of the swash-plate type comprises a control member angularly adjustable about the axis of rotation so that the arcuate length of the inlet and exhaust ports in the port member is variable, one end of each length of arc being at a point fixed with respect to the port member. Projections 30, 32 in the inlet and outlet ports 20, 21 respectively of the rotatable port plate 22 define the ends of the effective piston strokes. The angle is chosen so that the compression or decompression of the liquid in each cylinder results in the pressure therein being the same as that in the port with which it is about to communicate. In an alternative embodiment (Fig. 6) radial slots 38, 39 are provided in the plate and as each cylinder port moves through the arc 0, the port is closed. Anticlockwise rotation of the plate allows communication between the cylinders and ports 20<SP>1</SP>, 21<SP>1</SP> respectively through the slots 38, 39 until the same cut off point as before is reached, but earlier communication with the ports 21<SP>1</SP>, 20<SP>1</SP> is established when the plate is rotated clockwise. Specifications 893,848 and 934,851 are referred to.

Title: Stock feeders
IPC: F16H43/00
Filed: 1973-02-27
Abstract: 1422869 Feeding metal strip; measuring workpieces A R ST DENIS 27 Feb 1973 [29 Feb 1972] 9503/73 Headings B3W and B3B Metal strip is fed from a coil 13 intermittently to a power press (not shown) by at least one pair of ribbed feed rolls 31, 32 driven by an hydraulic motor (35) (Fig. 2, not shown) powered by an hydraulic pump 60. A spring-urged roller 44 urges the strip against a measuring wheel (not shown) which is mounted on a shaft carrying a photo-electric rotary transducer 43 connected to an electronic counter 47. The counter 47 controls solenoid-actuated valves 63-65 in fluid conduits connecting the pump to the motor. In operation, at the start of the feed stroke, all the valves are actuated so that two return paths, through valves 64 and 65, are open for fluid flow from the motor and the strip is advanced at maximum speed. When a predetermined substantial portion of the feed increment has passed the measuring wheel, the valve 65 is closed so that only the fluid return path which includes a flow control device (70), Fig. 6 (not shown), is open and the feed speed is reduced. When the complete feed increment passes the measuring wheel, the counter 47 closes valves 63, 64 too, ending fluid flow to the motor and preventing strip movement in feed or return directions. A second solenoid (SOL 4) in valve 63, Fig. 6, not shown, is used only for reversing the direction of travel when an operator is manually jogging the device into alignment for automatic operation. Upstream of the measuring wheel are straightening rolls 49, 50 and vertically mounted guide rollers 57 adjustable along a slot in a box beam 55. The rolls 31, 32 are connected by gears (33), (34), Fig. 2; alternatively a motor may be provided for each roll.
