Filed: 1972-12-27
Abstract: 1392950 Alphanumeric displays PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 27 Dec 1972 [28 Dec 1971] 59635/72 Heading G5C [Also in Division H1] A control circuit for a display tube (see Division H1) comprising a plurality of groups of cathodes Ka1-Kj1 to Ka8-Kj8, each arranged as shown in Fig. 1, an anode A, auxiliary anode T1-T8 and a screen electrode S, includes means for applying oppositely directed voltage pulses to the auxiliary anode and cathode strips of a selected group to produce a discharge in that group, and means for applying a negatively directed voltage pulse to the auxiliary anode of a group on cessation of a discharge in that group. A transistor switch between the anode A and a voltage source 52 is alternately in the open and closed condition for times of 0À1 and 1 m. sec. respectively. A ring counter is operated synchronously with the transistor switch to close switches P1 to P8 successively to supply voltage pulses to the auxiliary anodes T1 to T8 via capacitors C1 to C8. The closing of switches P1 to P8 is synchronized with the output of a coding device which opens those switches Pa to Pj which correspond to the cathode strips a to j which it is desired to energize for each of the matrix groups. The negative poles of all the voltage sources are connected to terminal 51. The switches P1 to P8 and Pa to Pj may all be integrated in a single MOST circuit of the p-channel type or alternatively of the n-channel or of the complementary type (Figs. 4, and 5, not shown). The MOST circuit may also incorporate the coding device.

Filed: 1972-12-29
Abstract: 1422140 Thermally responsive actuating elements TEXAS INSTRUMENTS Inc 29 Dec 1972 [1May 1972] 60052/72 Addition to 1395420 Heading G1D In a thermal actuator comprising a casing 12 in which is located a chamber 48 accommodating a heat expansible medium 64, the medium is heatable by an enerizable heat source 92 comprising an electrical resistance having a steeply sloped positive temperature coefficient above an anomaly temperature, to urge a piston 26 from a retracted position to a protracted position, provision being made for the medium to continue to expand once the piston 26 has reached its fully protracted position. The chamber 48 may be made of brass and as shown comprises a cylindrical body portion 50 connected at one end to a sleeve portion 52 by a truncated cone shaped portion 54 and at the other end to a thermally conductive end-plate defining a base 58 and a sleeve 62 extending inwardly of the chamber. The heat expansible medium 64, which may be wax, is retained in the chamber 48 by movable piston heads 66, 68 which are associated with seals 74, 76 and which bear respectively on a rod portion 46 of the piston 26 and a thermally conductive plate 82. When electric current is directed by way of terminals 84, 86 and elements 90 and 94, 96 the heat energizable source 92 provided by a wafer of a material such as barium titanate ceramic doped with lanthanum and, the temperature of the medium 64 increases so as to urge the piston 26 upwardly against the action of a spring 30. In its fully protracted position and upon continued heating of the medium 64, the piston 68 and chamber 48 move relatively to each other such that the chamber 48 is displaced upwardly in the casing against the bias of a spring 78 to cause the base 58 to disengage from the heat conductive plate 82. The chamber 48 then reaches a position of equilibrium within the casing. Instead of the chamber moving relative to the casing, the piston 68 may be separated from the plate 82 by a spring (118) Fig. 11, (not shown) which compresses and allows the medium to expand when the piston 26 is in its fully protracted position.

Title: Texturizing of yarn or filaments
IPC: D02G1/10
Filed: 1970-12-31
Abstract: 1311350 Edge and friction crimped yarns ALLIED CHEMICAL CORP 31 Dec 1970 [16 Jan 1970] 62023/70 Headings D1F and D1W A process for texturizing thermoplastics filaments or yarn comprises feeding the yarn under tension in sliding frictional engagement over a crimping element while the element is being advanced in the direction of longitudinal movement of the yarn, relative movement between the yarn and the element being maintained. In a preferred embodiment, yarn 12 is taken from a supply 11, passed through a tension regulator 13 and fed to a crimping element 10. The crimping element 10 comprises a frame having end plates 29 between which are mounted first and second guide rollers 15 and 16 and a crimping blade 24 having a knife edge 21. The crimping blade is adjustable radially of the end plates 29 which are caused to rotate in the direction of yarn travel at a different speed to the yarn. The yarn passes round the rollers 15 and 16 and over the edge 21 of the blade 24. The tension in the yarn leaving the edge is increased relative to the tension in the yarn approaching the edge, and if it is desired to pass the yarn several times round the rollers and over the edge, the yarn may be passed round a tension reducing godet roll 51 and separator roll 50 between the successive passes. The crimped yarn is then wound at 52. The yarn produced has a helical crimp which is preferably relaxed by steam treatment. Depending on the relative speeds of the crimping element 10 and the yarn, the yarn produced may be intermittently crimped or completely crimped along its length. A heater 25 may be positioned adjacent the blade 24 to maintain the yarn at the desired temperature. In an alternative embodiment, the crimping element comprises a roller having a helical blade on its external surface: One or more of these crimping elements may be arranged sequentially depending on the effect to be achieved in the yarn. In another embodiment, the crimping element comprises a blade and contiguous heater mounted on a frame which performs a planetary motion around a driven godet roll, the yarn being passed a number of times around the godet roll and the crimping element.

Title: Matrix addressing of opto- electric displays
IPC: G09G3/36
Filed: 1978-07-24
Abstract: A matrix display comprising an electro optic display having a layer of display material contained between two spaced substrates carrying m X and n Y electrodes arranged in a matrix formation to give an m x n element matrix, is addressed by a first series of m different coded waveforms applied one to each X electrode simultaneously, and a second series of coded wave- forms applied simultaneously to the Y electrodes. This second series of waveforms has codes different from one another and from the first series of waveforms. Additionally each code in the second series is related both to the codes on the X electrodes and to the information required to be displayed at each element along its associated Y electrode. As a result selected elements receive an r.m.s. voltage below a display effect threshold whilst others receive an r.m.s. voltage above threshold to collectively display the required information. The codes may be two or more level codes. Two level codes, i.e. binary codes, may be pseudo random series or orderly binary codes. As shown the codes are 6-bit binary codes stored respectively in ROMCx and ROMy with m and n equal to 4. The electro optic display may be a liquid crystal or an electroluminescent display. <IMAGE>
