Title: Electronic stores
IPC: G11C11/06
Filed: 1971-07-19
Abstract: 1355504 Magnetic storage systems PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 19 July 1971 [22 July 1970] 33714/71 Heading H3B In a multi-plane word organized core store an additional plane of cores is provided lacking inhibit wires, this latter plane being used to provide signals to trigger a reading strobe pulse for the remaining planes. Fig. 3 shows planes each with conventional row and column drive lines, and each having a sense conductor; the first 18 planes have inhibit lines, and have sense amplifiers V 1 -V 18  which can be strobed. The sense line of the additional plane 19 is connected to a device AG which gives a strobe pulse output to the sense amplifiers V 1 -V 18  a fixed time after receiving an output on the sense line. In planes 1-18, which have inhibit wires, there are inevitably several remanent states in which cores may be set by single and coincident half read and write signals, and reading noise in their sense conductors cannot be cancelled by the usual folding techniques. In the additional plane however such cancellation is possible since there is no inhibit wire, and the signal which is fed to the pulse device AG is thus largely noise free. This enables an accurately set strobe pulse to be generated, independent of parasitic capacitances in the planes. The configuration of sense conductors used is shown in Fig. 6a for the first eighteen planes, the arrangement being such that each plane has four sense conductors of which two Pa<SP>1</SP> and Pa<SP>11</SP> are shown each covering two quadrants of the plane and threading the cores in opposite directions. Such a pattern ensures that the output on the sense wires, while not noise free, occurs at much the same time as associated noise wherever the core is located in the plane. This allows the time of the strobe pulse to be accurately set. Because in large planes the amplitudes of the sensed signals vary according to the core location, the sense line in the additional plane is arranged in the opposite direction to those in the other planes, as shown in Fig, 6b. The overall system is then as shown in Fig. 8, each plane having two strobable sense amplifiers controlled by a pulse device AGa<SP>1</SP> or AGa<SP>11</SP> connected to a sense line of opposite direction in plane 19. This causes the strobe pulse to occur at such a time relative to selection of a given word location in planes 1-18 that the final strobed output is independent of the actual location.

Title: Colour picture tube
IPC: H04N9/26
Filed: 1966-07-27
Abstract: 1,131,277. Colour television tubes. SONY CORP. 27 July, 1966 [30 July, 1965], No. 33726/66. Heading H1D. The colour-switching coils 13, 14 of a colour television tube using a single electron beam are situated one on either side of the deflection yoke 12. The tube may be of the type using either dot-triads or lines of phosphors, the various phosphors being excited by controlled deflection of the beam b. In particular, the colour-switching coil 13 causes divergence of the beam and the coil 14 causes convergence through an angle greater than the angle of divergence (see Fig. 4, not shown), the coils being suitably dimensioned and connected in series opposition to have this effect. The arrangement is such that these deflections are accomplished whilst the beam is in the vicinity of the tube axis whereby colour distortion is avoided. The Specification also discusses the variation in power consumption with position of the coils 13, 14 and it is stated that the ratio L 1 : L 2  should be in the range 0À4 to 1À1. The distance L 2  is measured to a grid 8 having conductors opposite the demarcation lines of the phosphors. A high positive potential is applied to the screen and to the conductive layer 10. A lower potential is applied to the grid 8. The coils 13, 14 may each consist of two saddle-shaped windings about an annular core, the core of coil 14 being of frusto-conical formation. The axially-extending portions of the windings lie between the cores and the surface of the tube, and the cores may be internally shaped to accommodate the windings.

Abstract: 521,697. Grinding hard materials. NAGY, A. Nov. 19, 1938, No. 33733. Drawings to Specification. [Class 60] Hard metals, such as sintered carbides of boron, tungsten, vanadium, tantalum and titanium generally associated with a carrier metal such as cobalt are suspended in a bath of liquid having hard particles in suspension and are acted upon by a moving carrier body, of relatively soft material such as cast iron, copper, lead or an artificial resin, in which hard particles become embedded as it approaches the hard material to be ground but are shed by the carrier body after having traversed the hard material. Flat or cylindrical surfaces may be produced and the carrier may be profiled to reproduce a corresponding shape. A tubular carrier member may cut a hole in a block or a disc may act between. For making drawing dies, a carrier for example of square section and having a taper end is reciprocated in the die in the bath being gradually fed deeper until finally the hole is finished by the parallel portion.

Title: Improvements in or relating to circuit arrangements in automatic telephone systems

IPC: H04M15/04
Filed: 1962-09-07
Abstract: 975,997. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. Aug. 26, 1963 [Sept. 7, 1962], No. 34345/62. Heading H4K. Periodic operation of a subscriber's meter is effected by a 4-stage binary counter MA . . . MD which is associated with an outgoing relay set ORS and is controlled by recurrent X pulses at intervals of 500 ms. on lead AX and recurrent D pulses at intervals of 18 sec., for example, on lead TPD. The toggle pairs are controlled by the pulses through a number of AND gates. When the relay set is seized, earth on lead TPH renders transistors T2, T3, T6 and T8 conducting, so that the initial state of the counter (left to right) may be regarded as 0100, and this state is maintained until a reply signal arrives on lead TDJ. When this occurs the next X pulse switches MA to give the state 1100, which is maintained by the continuance of the reply signal, thus guarding against a momentary surge simulating that signal. The next X pulse switches to the state 0010, in which the counter is no longer dependent on the reply signal. At this time, transistor T9 conducts and operates relay CP to effect metering. The third X pulse gives the state 1010 and releases CP. Further, X pulses are now ineffective and the counter is stepped on by successive D pulses. After the 11th D pulse, when 3 minutes have elapsed, the state is 0000 and CP operates to effect metering again. From this state two X pulses are necessary to render the counter sensitive to further D pulses, and metering occurs again after the 21st D pulse.

Title: Recovery of phosgene
IPC: C01B32/80
Filed: 1953-12-10
Abstract: Phosgene is recovered from waste gases containing phosgene and hydrogen chloride by passing the gases upwardly through a cooling apparatus which cools the gases to a temperature below the boiling point of phosgene but above that of hydrogen chloride, e.g. - 40 DEG to - 60 DEG  C., down which cooling apparatus liquid phosgene, condensed from the waste gases by the cooling, trickles under gravity.  Waste gases at 0-5 DEG  C. enter tubular cooler 2, cooled by boiling difluorodichloromethane or difluoromonochloromethane, at 1, and pass upwardly <PICT:0737442/III/1> countercurrent to condensed liquid phosgene, which discharges into tank 4.  Uncondensed gases pass through pipe 5 to washer 6, where the hydrogen chloride is extracted by water entering at 8 and is withdrawn as an aqueous solution at 7.  Any inert gases remaining are exhausted through pipe 9 by fan 10, which maintains a slight subatmospheric pressure in the whole apparatus.  In alternative apparatus (Fig. 2, not shown) a pressure relief valve, preferably automatic, is inserted in pipe 5, so that the cooler 2 is maintained under slight superatmospheric pressure, e.g. 100-200 mm. of water, while the remainder of the apparatus is maintained by fan 10 under subatmospheric pressure, in order to avoid moisture being sucked into the cooler in the event of leaks, with consequent contamination of the phosgene by corrosion and metal chlorides.

Abstract: 756,017. Volume compression and expansion. GENERAL ELECTRIC CO. Nov. 29, 1954 [Dec. 7, 1953], No. 34545/54. Class 40 (4). [Also in Group XL (c)] The collector bias is varied in the same or opposite sense as the magnitude of the signal being amplified by the transistor to give volume expansion or compression or automatic gain control. An A.G.C. source 27 of negative potential is connected over resistor 29 to lower the base potential of transistor 11. The increased collector current causes a fall in the negative bias due to resistor 21 and hence in the gain of the stage. The potential of the A.G.C. source is reversed for volume expansion. In a modification, Fig. 3 (not shown), resistors 23, 29 are replaced by diodes, thereby reducing the load on the A.G.C. source. The A.G.C. signal may be derived in the manner indicated in Specification 756,016.

Abstract: 1,248,844. Crimping yarn. DEERING MILLIKEN RESEARCH CORP. 9 July, 1969 [10 July, 1968], No. 34675/69. Headings DID and D1F. A method of uniformly crimping a running strand of thermoplastic yarn comprises the steps of a) continuously withdrawing a yarn strand 21 from a supply source, b) positively feeding the strand into a heating zone 14 to maintain the strand under relatively low tension in the heating zone to facilitate its contraction during heating, c) heating the strand to between its first and second order transition points, and d) pulling the heated strand about a surface 16 of frictional engagement to continuously bend the strand along its length and impose latent stresses therein, while controlling the rate of withdrawal of the strand from the surface 16 to maintain a uniform tension in the strand leaving the surface 16. In operation, yarn 21 is withdrawn from a pirn 24 and positively fed by driven nip rolls 22, 23 to a plate heater 26. On leaving the heater 26, the yarn 21 is bent round a blade member 28 to impose latent stresses in the yarn. The yarn is withdrawn from the blade 28 by a pair of driven tapered nip rolls 32, 34, and is finally wound on a ring and traveller spinning device 30. Situated between the blade 28 and the tapered nip rolls 32, 34 is a tension sensing device comprising a pivoted lever 50 with an eyelet at one end and a weighted spring 54 at the other.- The pivoted lever is biassed for rotation in a first direction and any change in the tension of the yarn causes the lever to pivot and the yarn is correspondingly shifted along the surface of the tapered nip rolls to thereby increase or decrease the rate of withdrawal of the yarn from the blade 28. The nip rolls 22 and 32 and the ring spindle are driven by means of pulleys and belts 36, 38, 40 from a common drive motor 42, the speed of rotation of each being set by selection of the size of pulley. A pneumatic piston-type damping device 58 may be provided to prevent over-correction of the tension by the lever 50.
