Title: Improvements in and relating to core blowing or ramming machines
IPC: B22C11/00
Filed: 1957-11-18
Abstract: 818,977. Core-making machines. MASCHINENUND WERKZEUGFABRIK KABEL VOGEL-SCHEMMANN A.G. Nov. 18, 1957 [Nov. 28, 1956], No. 35828/57. Class 83 (1). In a core-blowing machine control means such as a push-button &c. for actuation of a compressed-air feed valve controlling two or more operating steps is disposed on each side of the machine. One operator brings a core-box into position for blowing, and a valve is positioned so as to actuate a pneumatic piston 5 to close the sand container 1 by a slide 3. Movement of the slide also opens a safety valve 8, so that actuation of push-button 11<SP>1</SP> by the operator will cause pressure air to travel via line 9, valve 8, line 91, valve 11, line 16, non-return valve 17 and line 17<SP>1</SP>, to open the main-feed valve 14, thereby causing the operations of the machine, e.g. box-clamping table-lifting, blowing &c., to take place automatically. Thereafter the blown box is removed, and a second operator may insert his empty core-box into the machine and initiate the operating sequence by actuation of the push-button 10<SP>1</SP> on his side of the machine.

IPC: H01L21/18
Filed: 1957-11-20
Abstract: 878,920. Semi-conductor devices. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Nov. 14, 1958 [Nov. 20, 1957], No. 36198/57. Class 37. A semi-conductor device, for example a rectifier or transistor, comprises one or more PN junctions each formed by fusing together a body of silicon of one conductivity type and a body of silicon germanium alloy of the opposite conductivity type. The fusing process may consist of holding wafers of the two materials in contact while heating in inert gas or vacuo in a muffle or continuous belt tunnel furnace to fuse their surfaces together. Alternatively, if the melting points of the bodies are markedly different a pellet of the lower melting point material is melted on the surface of the other material and then cooled to form a composite body therewith. Ohmic contact is subsequently made to the P-type zones of the composite body by alloying gallium-gold or indium-tin alloys thereto, and to the N-type zones by means of gold-antimony or tin-arsenic alloys. The device is finally etched to clean the PN junctions.

Title: Associative Memory.
IPC: G11C15/02
Filed: 1967-08-08
Abstract: 1,187,850. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 8 Aug., 1967 [31 Aug., 1966], No. 36324/67. Heading H3B. [Also in Division G4] In an associative memory, columns of magnetic memory elements store respective tags and receive equal amounts of electromagnetic energy, the elements being perturbed in accordance with an input tag, and the amount of energy remaining in each column after absorption by the elements of that column being measured directly to identify the most-closely matching column. In Figs. la, 1b microwave energy from an oscillator 5 is supplied to branch lines 8, 34 threading anisotropic (hard axis) thin-film magnetic elements 3 constituting the columns of the two matrices shown. A bit is stored at each intersection of a column 3 with a perturb row line 15, 25 by write-in means not shown. Each column in Fig. 1a stores a tag and each row in Fig. 1b stores a corresponding data item. Such bits of an input tag in an input register 12 as are not masked out by a select circuit 16 control bi-polar pulse generators 14 to drive the perturb lines 15, so that at each bit storage position in the Fig. la matrix, the microwave energy from oscillator 5 is attenuated less and more in the cases of agreement and disagreement (between input and stored bits) respectively. The output energy level from a given column produces an output from a respective threshold amplifier 22 in the case of a complete match with the input tag, to read out the corresponding data item from the matrix of Fig. 1b as shown through amplifiers (diode detectors) 36. The threshold of the amplifiers 22 is adjusted by sources 28 in accordance with the number of bits masked out by select circuit 16, and if a complete match is not found may be successively lowered to get the closest match. In a first modification, an extra perturb line in the Fig. 1a matrix is controlled by a variable pulse generator as a substitute for having the threshold on the amplifiers 22 variable. In a second modification the bits of the input tag are gated to the pulse generators 14 in turn by a ring counter. In this case, a single bit mismatch in a given column produces an output from the corresponding threshold amplifier 22 to set a respective latch. The latch (if any) still not set at the end of the tag comparison selects the data item to be read out.

Abstract: 1,154,670. Sewing machines, stitched seams. VIRGINO RIMOLDI & C. S.p.A. 30 July, 1968 [7 Sept., 1967], No. 36347/68 Heading D1G. [Also in Division A3] A sewing machine is provided with means for folding a tubular strip about an edge of a workpiece and comprising a fixed guide provided with fins and positioned near the presser foot, and a movable guide in the form of a longitudinally-movable bar terminating in a pair of spaced-apart branches, the arrangement being such that when the tubular strip is threaded on the bar and the latter is moved to an operative position, the fins enter the space between the branches and fold the tubular strip into U-shape for embracing the workpiece edge. The fixed guide 16 is secured by a flange 18 to the sewing machine base, and has a work-supporting surface 16<SP>1</SP>, a pair of vertically-spaced initial guiding fins 20, a pair of intermediate vertically-spaced folding fins 21 and a final horizontal centrally-positioned folding fin 22. The movable guide 17 is in the form of a bar 23 slidable on rollers between fixed plates and formed at its inner end with a pair of vertically-spaced branches 24. In use bar 23 is retracted and a tubular portion of a knitted binding strip 40, having a flat extension 43, is threaded thereon. Bar 23 is then moved to the operative position in which it is held by a spring catch. During this movement the fins 21, 22 pass between the branches 24 to fold the tubular portion into two arms 48 which embrace the edge of a knitted fabric workpiece 44 supported on surface 16<SP>1</SP>. Arms 48 are sewn to said edge by a seam 42 under the main pole (10) of the presser foot 6. The adjacent body of the workpiece passes under an auxiliary pivoted sole 11 biased downwardly by a wire spring 12.

Abstract: 1,011,430. Television. PYE Ltd. Aug. 8, 1963 [Sept. 26, 1962], No. 36477/62. Heading H4F. A television receiver, Fig. 1, has a first cathode-ray tube M for black-and-white picture reproduction, a second cathode-ray tube C for colour reproduction, switching means S for bringing the appropriate tube into use in accordance with the type of signal to be received and a screen shutter A, Fig. 2, adapted to move from one tube face to the other, the arrangement being such that the switching means and shutter operate in conjunction. The switching means directs the video signal either to the cathode of tube M or to the three cathodes of tube C via a colour decoder CD and also connects the output of the synch. separator to the line time-base and E.H.T. generator T1, T2 of the selected tube. The cathode heater of the idle tube may also be de-energized. To allow for the consequent delay in warming up when operating the switching means to change tubes, a 20 seconds mechanical or electrical delay may be incorporated so that one tube remains operative until the other is ready. Alternatively both cathode heaters may remain energized and a voltage may be applied to an electrode located near the cathode in the idle tube to prevent cathode damage by returned electrons. Movement of the shutter, which may be by electric motor, operates switching means S and is delayed when the delayed operation referred to above is involved.

Title: Improved door checking appliance
IPC: E05F3/20
Filed: 1959-10-28
Abstract: 906,995. Door checks. MORRIS, J. N., and WILLIAMS, R. M. Oct. 19, 1960 [Oct. 28, 1959], No. 36492/59. Addition to 863,785. Class 65 (1). In a door-checking appliance as claimed in the parent Specification the one-way clutch device is operative in the direction of door closing movement and means are provided for rendering it inoperative at a predetermined point during such movement so that there is no relative rotation between the rotor and the cylinder during the remainder of the closing movement or the rotation is so slight that there is little or no damping resistance. The invention is shown incorporated in a door hinge. The clutch is a close-coiled spring 10 arranged partly in a bore 12 in the rotor 13 and partly in a sleeve 16 fixed in the upper hinge knuckle 17 of the fixed hinge plate 18, and the end 21 of the spring projects through a slot 20 of predetermined circumferential extent formed in the wall of the sleeve and extends into the path of movement of an abutment member 22 fixed to the inner surface of the cylinder 14. The clutch is arranged so that the resistance to slipping of the spring is slightly greater in the bore 12 in the rotor than it is in the sleeve 16. When the door is opening the cylinder 14, fixed to the moving hinge-plate 15, rotates in a clockwise direction (Fig. 2) and carries with it the rotor and the spring which first slips in the sleeve 16 until the end 21 abuts the edge of the slot 20 and then slips in the bore 12. When the door is closing the clutch is operative until the abutment member 22 engages the end 21 of the spring, after which further rotation of the cylinder in the door-closing direction tends to wind up the spring which will therefore be able to slip in the sleeve 16 so that there will be little or no restraint from the damping fluid.

Abstract: 1,112,970. Circuits employing bi-stable magnetic elements. MULLARD Ltd. 26 Aug., 1965, No. 36657/65. Heading H3B. A laddie for use in logic operations comprises a magnetic core having at least four rungs of equal cross-section and spaced apart by equal major apertures, each of the rungs including a minor aperture dividing each rung into two legs each leg being of equal cross-section. The core is provided with a drive winding 21 which is wound in one sense on input rungs 1, 2, 3 and in the opposite sense on the output rungs 4, 5, 6 and a prime winding 22 wound on the a legs of the output legs 4, 5, 6 and in a figure-of-eight manner around the b legs of these rungs. Input windings 23, 24, 25 are wound through apertures 14, 15, 16 on the a legs of input rungs 1, 2, 3 and a sum output winding 26 and carry winding 27 are wound on output rungs 4, 5, 6. In operation alternate positive and negative pulses are applied to the drive winding and a slowly rising prime pulse is applied of the opposite polarity to the previous drive pulse and of sufficient m.m.f. only to switch flux around a minor aperture but not around a major aperture to prime winding 21. If one binary input signal is applied to one of the input windings 23, 24, 25 during the application of a drive pulse and of the same polarity thereof, then after priming, the next drive signal of opposite polarity to the input signal will switch flux around leg 4b. Since this leg is wound by the sum output winding 26 an output signal will be induced therein. As no flux reversal occurs in rungs 5, 6 at this time no output is induced in carry winding 27. If two inputs are present then after priming, application of the next drive pulse causes flux reversal in legs 4b and 5b which causes equal and opposite signals to be induced in sum winding 26 and an output signal to be induced in carry winding 27. If all three input signals are present, then after priming the next drive pulse causes flux reversal in legs 4b, 5b and 6b which results in a net output signal in the sum winding 26 and an output signal in carry winding 27.
