Abstract: 1,053,474. Electronic counters; selective signalling. LA TELEMECANIQUE ELECTRIQUE. April 27, 1964 [April 26, 1963], No. 17391/64. Headings G4A and G4H. A reversible counter comprises a ring of ten NOR gates AT1-ET1, AT2-ET2 such that five successive gates are always on and opposed pairs form flip-flops. The_NOR gates have outputs A-E. A-E which assume 1 or 0 condition when the gate is on or off. According to whether the count is to be forward or backward so VC applies an input to AND gates PCI, PCP or VD applies an input to PDI, PDP. Input pulses H feed a logical network including two flip-flops BS, BG so that odd and even pulses mark terminals S1. S2, respectively, so applying further input to PCP, PDP or PCI, PD1. Two out of four conductors CI, CP, DI, DP are thus marked and together with outputs from A-E, A-E energize a selection of AND gates CPACPE, CIA-CIE, DPA-DPE, DIA-DIE to shift the pattern one step forward or backward as the case may be. Read-out is effected by a diode matrix, Fig. 2a, only the first and last of the five gates which are on being necessary to identify a digit. Carry is effected from the diode matrix to lead H(n + 1). In forward carry flip-flop BG of the lower denomination reverses when a count of 9 is attained, BS reversing when the marking disappears. In subtractive carry BS reverses as soon as the marking appears. Resetting is performed by a pulse on lead Mz which sets all the right-hand stages of flipflops BS, BG, BA-BE to O.

Abstract: 1,143,775. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. 7 April, 1966 [13 April, 1965], No. 15678/65. Heading H3B. [Also in Division H1] Each row and column line of a magnetic storage matrix comprises a conductive loop, Fig. 18, the crossing points of the loops being contained between an isotropic magnetic storage film and a layer of high permeability magnetic material. The film and layer are in contact at all regions except those where the conductors are located so that each storage location provides a plurality of flux paths. Fig. 14 shows the flux paths produced when a binary one is stored by pulsing a horizontal digit loop and a vertical word loop simultaneously. The flux pattern for a binary zero is shown in Fig. 15, in this case the half-current pulse in the digit loop being of reversed polarity. When read out is effected by a full current pulse in a vertical read loop, an output pulse is induced in a horizontal sense loop and the flux pattern is charged to that shown in Fig. 16. The storage film consists of a 97% Fe, 3% Ni film deposited on a copper substrate, the matrix of conductors being formed by a printing process on the storage film. The magnetic paths are completed by a plate of high permeability ferrite, Fig. 10 (not shown), which has two orthogonal sets of parallel slots which leave a series of rectangular posts. The plate fits over the substrate, film and conductor matrix assembly with the posts in contact with the storage film; the contacting surfaces being plane polished. Instead of a ferrite plate a similar grooved copper plate may be used which is coated with a high permeability magnetic material such as nickel-cobalt alloy. Alternatively the nickel cobalt alloy may be directly plated on the matrix assembly to avoid the use of a slotted plate. The matrix assembly may be formed by electroplating the copper substrate 1, Fig. 2, with the magnetic film 2, followed by an oxalate conversion coating 3 and a layer of metal etch resist 4. A strip 5 of the etch resist along the required path of a conductor and of greater width is exposed to ultra-violet light, the whole surface being then copper plated. The copper layer 6 is coated with a layer 7 of photo resist, a strip 8 of the same width as a conductor to be formed being exposed to ultra violet light. The unwanted parts of the layers 4, 6 and 8 are removed by developing and etching, Fig. 4. A second overlying conductor is then applied by coating the structure with metal etch resist 15, Fig. 5, followed by layers of copper 19, photo resist 18 and metal etch resist 20, strips of the resists being exposed as for the first phase of construction. Finally the unwanted portions of the assembly are removed by etching, this etching process removing the oxalate coating 3 from the regions of the magnetic film not covered by conductors.

Abstract: 1,251,224. Vehicle levelling valves. CLAYTON DEWANDRE CO. Ltd. 14 Aug., 1969 [21 Aug., 1968], No. 40007/68. Heading B7D. A levelling valve for a vehicle suspension system comprises a body 11, a lever 1 for connection at one end either to a vehicle axle or to a vehicle suspension member, and pivotally mounted at the other end on said body, a rotatable shaft 8, a piston 18, an operating member 16 connected to said shaft and having an end portion received in a slot 17 in said piston, a cylinder 19 housing said piston and filled with damping fluid, and a valve spindle 20, the arrangement being such that movement of said lever rotates said shaft and operating member to cause the latter to move the piston from a central position in said cylinder, whereby the valve spindle moves for connecting one or more suspension units of a vehicle either to a source of fluid pressure or to exhaust depending on the direction of movement of the lever, movement of the piston towards the ends of the cylinder being damped and means, such as non- return valves, being provided to allow undamped return of the piston to its central position. The embodiment shown may be mounted with the lever connected to the centre of a vehicle axle or anti-roll torsion bar. Alternatively, where such central mounting is not possible, two such valves may be used and connected together so that the suspension units are not connected to supply or exhaust unless both valves are simultaneously operated (Fig. 4, not shown). Where side-to-side transfer of fluid between suspension units on the same axle is to be prevented, a modified form of valve (Fig. 5, not shown), is used. Where this valve is mounted with the lever connected to the centre of a vehicle axle or anti-roll torsion bar, the conduits to and from the valve and suspension units are connected such that side-to-side fluid transfer is not possible (Fig. 6, not shown), but where a centrally-mounted valve cannot be accommodated, two modified valves are interconnected such that the suspension units are not connected to supply or exhaust unless both valves are simultaneously operated.

An extrusion machine for producing coated cores, e.g. a core of jam or cream within a covering of bread or cake dough, comprises a tube 12<SP>1</SP> through which the core material is fed from a device 1, a coaxial sleeve 13, an independent flight 12 which feeds the coating material to annular orifice 17, and a ring 16 which defines the extrusion orifice and is rotated within housing 10. As shown, tube 12<SP>1</SP> is rotated via a sprocket 15 with consequent rotation of flight 12 attached to the downstream end of the tube. Ring 16 is rotatably driven by tube 12<SP>1</SP> via gear chain 20, 21, 22 and 19, the speed of rotation of the ring preferably being less than that of tube, e.g. revolution ratios in the range 93 : 100 and 96 : 100. Ring 16 may be rotated in the opposite direction to tube 12<SP>1</SP>. Sleeve 13 may be stationary or rotate in the opposite sense to flight 12. As shown, the coating material is fed to flight 12 by a conventional screw impeller 8, but may be fed by an impeller as more fully described in Specification 1,222,856 (see Div. B7-B8). It is stated that the apparatus is particularly suitable when the coating material is of relatively high viscosity, the feed thereof being facilitated by the independent nature of flight 12 and sleeve 13 with the surface of the coating being smoothed by ring 16.
