Title: Data storage apparatus
IPC: G11C16/04
Filed: 1971-04-19
Abstract: 1281148 FET storage circuits NATIONAL CASH REGISTER CO 19 April 1971 [2 March 1970] 21824/71 Heading H3T [Also in Division G4] An MOS transistor A feeds control signals to the gate 12 of an MNOS transistor B to change the V-I characteristic of the latter between two discrete positions (Fig. 4, not shown) which correspond to a stored "0" and "1" respectively. When the gate 8 of MOST A is held at OV while its source 5 is at + 50V (lines A, B, time IV, Fig. 2, not shown), the MOST applies a high positive voltage to the gate 12 of MNOST B, thereby shifting its characteristic to the right (Fig. 4, not shown). A +60V at MOST A gate (time II) would inhibit this action. To shift the characteristic to the left, -50V is applied to MOST A source and - 60V to its gate (time VIII) to discharge MNOST B gate. A OV at MOST A gate (time VI) would inhibit this action. To read the state of MNOST B, + 10V is applied to its source 11, and a meter 30 measures the resulting current, which is either zero or appreciable (I, III, IX or V, VII, Fig. 4, not shown). The substrate is maintained at +50V. A plurality of these pairs of transistors is formed on one wafer (2, Fig. 5, not shown) in a matrix store. Write X and write Y units (60, 102) are respectively connected to the MOS A gate lines (52 &c) and source lines (94 &c.) and read pulse and sense units (42, 30) are connected respectively to the MNOS B source lines (34 &c.) and drain lines (25 &c.).

Filed: 1952-09-01
Abstract: 715,252. Composite casting. KNAPP MILLS, Inc. Sept. 1, 1952, No. 21943/52. Class 83 (1). A metal sheet is coated with metal by forming the sheet into a tray by folding the edges or providing an enclosing rim, floating the sheet on a pool of molten metal, heating the sheet by contact with the pool, applying molten coating metal to the upper surface of the sheet, separating the sheet from the pool and then cooling it. The invention has particular reference to coating steel with lead. A submersible raft 6 is provided in a container of molten metal and the sheet 13 with the rim 12 secured thereon by clamps is floated on the molten metal 2. When it is heated sufficiently a pump 25 delivers the metal to the surface of the sheet. At the conclusion of the coating the raft 6 is allowed to rise and hold the sheet above the pool to allow it to cool. The raft may be dispensed with. Instead of a suction pump a container of molten coating metal may be suspended above the sheet on a rail so that it may deliver its contents to the sheet. The coating metal may be different from the metal forming the pool. The raft is depressed and elevated by screws 10 rotated simultaneously by sprockets 30, 31 coupled by a chain 28. Heating coils 5 are provided. Before coating, the plate should be cleaned by pickling in sulphuric or hydrochloric acid or shot-blasted and a bond provided on the steel. For this purpose solder is applied to the steel with the aid of a flux of ammonium, zinc or stannous chlorides.

Title: Improvements relating to colour television
IPC: H04N17/04
Filed: 1963-05-31
Abstract: 1,021,322. Colour television test apparatus. J. A. SHIPWAY. Aug. 24, 1964 [May 31, 1963], No. 21992/63. Heading H4F. A test apparatus for colour television receivers comprises a signal source 1 generating a black and white test picture signal the colour information from which is transmitted to the red, green and blue inputs of a matrix 2 via switches 3, 4 and 5 operated sequentially by a line-by-line switch generator 6, the matrix 2 producing chrominance signals " I " and " Q " and luminance signals " Y " in accordance with the transmitted information, and means for suppressing the chrominance signals during part of the test transmission so as to produce, in a correctly adjusted receiver, a test pattern composed of monochrome areas of equal hue formed respectively by the luminance signals only and the chrominance signals. In the area formed by the chrominance signals the luminance signals may or may not be suppressed. The chrominance signals may be suppressed during the first half of each line by means of half-line switches 8 so that the test pattern produced for example consists of two vertical grey scales positioned side-by-side, one of the scales being transmitted with the sequential chrominance signals suppressed. Synchronizing pulses from a source 7 control the line-by-line switch generator 6 and a half-line generator 9 which in turn controls half-line switches 8. -Instead of suppressing the chrominance signals for half of each line, the whole picture may be produced by the chrominance signals only, so that a colourfree black and white picture is formed when the receiver is correctly adjusted, or chrominance only for one or two colours and chrominance and luminance for the remaining colour or colours. The switches 3, 4 and 5 may be operated by a frame-by-frame generator instead of a line-by-line generator such as 6, or alternatively each line may be divided into separate parts, or groups of lines may be taken together, for example a colour change every three lines, the necessary condition being that each line, group of lines, or part of a line is a different colour on successive scans. The sequential transmission of the colour information gives a black and white picture frequency of one-third of the normal picture frequency or one-half if two primary colours are transmitted on one scan and the third on the following scan.

The bonds may be formed by hot calendering using an embossed roller. Polypropylene is exemplified but polyethylene, polybutene, polyisobutene, polybutadiene, polyvinyl chloride, polyurethane, polyamide polyethylene terephthalate and mixtures thereof may be extruded as bundles of filaments 114 by spinneret 14, the holes of which extend in one or more rows perpendicular to the direction of motion of foraminous receiving surface 20. The filaments are drawn in 18 by supersonic air flows. Guns 18 oscillate across carrier 20, thereby producing a random web 22. The web is lightly compacted between rolls 26, 28 and then pattern bonded at the nip between heated smooth surfaced roll 30 and heated embossed roll 32. Rolls 38, 40 serve to force the web against roll 30 over a major part of its circumference, both to provide pre and post bond heating, in order to produce stronger, more uniform bonding and in order to restrain the web from excessive shrinkage.

For 1-3 oz/yd<SP>2</SP> both rolls are maintained at 310-350F. The regular pattern of raised diamond-shaped areas on steel roll 32 bonds 5 to 50% of the web area with a bond density of 50 to 3200 bonds/in<SP>2</SP>. The bonds have an unfused bond area coefficient u.b.a.c. of 20% to 65%. The u.b.a.c. is determined by allocating each bond in 10 one inch square random samples of web to one of the following categories. 0-33% fusion, 33-66% fusion, 66- 100% fusion. The per cent fusion in a given bond is determined by observing the bond at 100X magnification under a stereomicroscope with a grid having 10 equal area portions placed over the bond. The fused area of a bond is that area wherein individual filaments cannot be identified. The u.b.a.c. is that percentage of the total number of bonds which are categorized as 0-33 % fused.

Abstract: 379,831. Wired wireless systems ; multiplex signalling. SIEMENS & HALSKE AKT.-GES., Siemensstadt, Berlin. Aug. 7, No. 22428, Convention date, Aug. 8, 1930. [Class 40 (v).] Telegraphic signals of different note-frequencies, and distant-control impulses up to 400 cycles, are all superposed on the speech currents and modulated on a common carrier-wave used for intercommunication purposes over the supply wires connecting say electric power stations. In transmission the audio-frequency currents are amplified at low frequency, whilst on the receiving side they are amplified at high frequency. A high-frequency valve-generator S, Fig. 2, is modulated (a) by direct-current telegraph impulses through a filter Gl; (b) by interrupted tone signals through a filter Tg applied tc the input of an amplifier V1; and (c) by speech currents from a subscribers microphore on the line T. Incoming signals pass from the line F to an amplifier E and are rectified at V2. The output from the rectifier is separated into (a) direct-current impulses which pans through to a relay GlR; (b) tone telegraph signals which pass through a filter Sp1 to a recorder Tg; and (c) speech currents which pass through a chain filter K1 to the subscribers receiver on the line T.
