IPC: G06K7/016
Filed: 1961-01-24
Abstract: 905,057. Sensing record-cards. DE STAAT DER NEDERLANDEN TEN DEZE VERTEGENWOORDIGD DOOR DE DIRECTEUR - GENERAAL DER POSTERIJEN, TELEGRAPHIE EN TELEFONIE. Jan. 24, 1961 [Feb. 3, 1960], No. 2749/61. Class 106 (1). A record card as described in Specification 845,050, having a number of columns of marking spaces each being in a light colour on a different coloured background, one of the spaces being filled in to indicate the data and each column having a synchronizing mark, is sensed by two identical sensing stations A, B, Fig. 1, each consisting of a row of photo-cells a-u equal in size to a marking space or the distance between them, the synchronizing marks being sensed by a group of three smaller photocells x, y, z and their outputs determine which of the photo-cells a-u shall be connected to storage means, the data stored from the two sensing stations A, B being compared. The transverse registry of the record is determined by the combination of photo-cells x, y and z which detect the synchronizing mark. The three signals are combined in circuit PS, Fig. 2, to produce an output on one of five lines 11-15, enabling one of five groups of gates. These correspond to normal registry (N) and displacements left (L), right (R), extreme left (UL) and extreme right (UR). To each of these groups of ten gates are connetted the appropriate ten of the data-sensing photo-cells a-u and there are ten output leads of which one will be marked according to the position of the filled-in space in the column being sensed to set one of ten triggers I-X. Stations A and B set the two groups of triggers I-X and Ia-Xa and these are compared at VG. A checking circuit C checks the one and only one of the triggers Ia-Xa is set. The background colour, e.g. a partially saturated red is such that it produces the same response in the photo-cell as an unfilled space. A filled space therefore produces a distinguishable signal.

Title: Improvements in or relating to the coagulation of aqueous dispersions of rubber and rubber-like materials and apparatus therefor
IPC: C08C1/14
Filed: 1944-02-15
Abstract: 572,030. Coagulating rubber. DUNLOP RUBBER CO., Ltd., TAYLOR, S. D., MADGE, E. W., and MURPHY, E. A. Feb. 15, 1944, No. 2762. [Class 70] Coagulating rubber.-Rubber-like material is coagulated from rubber latex, or from aqueous dispersions of rubber-like polymers, by continuously introducing a sheet-like stream of the dispersion substantially normally into a stream of coagulant, the two streams having the same width, permitting the mixture to flow together until the coagulum agglomerates, and continuously separating the coagulum from the liquid. Coagulant is delivered by a nozzle 2 having a rectangular cross-section on to a shoot 3 of the same width, the nozzle being inclined at a small angle to the shoot to prevent turbulence. The dispersion is fed to the coagulant through a rectangular nozzle 5 of the same width as the shoot 3, substantially at right angles thereto, and situated sufficiently above the coagulant stream, and distant from the nozzle 2 to prevent a build-up of coagulum. The rate of flow of the coagulant and dispersion are preferably the same. The mixture flows from the shoot 3 into a wider channel 6 down a. slope 7 on to the base 8 of such length and inclination to the horizontal that agglomeration is complete at the outlet. At the commencement of an operation, a plate 9 in grooves 10 ensures an initial accumulation of coagulum. Thereafter, the plate 9 is removed and the coagulum and liquid flow from the channel 6 on to a conveyer moving at such a rate that the sheet of coagulum is neither stretched nor buckled.

Title: Improved means for electrically heating saucepans, frying pans and other vessels
IPC: A47J27/00
Filed: 1955-01-31
Abstract: 779,207. Heating vessels by passing current therethrough. DUCKHAM, W. G. Jan. 31, 1955 [Feb. 8, 1954], No. 2882/55. Class 39(3) Metal vessels such as frying pans and saucepans are heated by passing a low voltage current through the bottoms of the vessels, the current being fed from a transformer to conductors secured to the bottoms of the vessels and pressure is applied to the conductors or the contacts,. which are moved into electric engagement substantially instantaneously on operation of the pressure-applying device. Two parallel copper rods or tubes 11 are secured as by soldering to the base of an aluminium or stainless steel saucepan 10. Contact rods 13 of a transformer 15 have conical ends engaging conical recesses at one end of each rod or bar 11, so that current passes between the rods through the bottom of the vessel. Good contact between the rods or bars 11 and the contact rods 13 is ensured by insulated metal bars 17 sliding in a block 18 and having conical ends pressed into conical recesses of the rods 11 by a toggle mechanism 19 operated by a lever 20. In Fig. 3 channel shaped conductors 21, 22 are welded to the bottom of the vessel and are pressed against the supply conductors 32, 33 from the transformer by two wedge-shaped halves 23, 24 of a plate of brass or other non-magnetic metal, insulated from each other and from a bracket 25 on which both halves are mounted. Flanges 26 on opposed sides of  the bracket 25 are connected to a spindle 28 sliding in blocks 29. The spindle 28 is rotated by a control knob 30 at one end and has at the other end a cam operating a micro switch 34 operated by a cam 38 on the spindle. The spindle 28 has also a cam 31 engaging the bracket 25 and is pulled forward so that the saucepan may be placed with its attached channel members 21, 22 resting on the supply conductors 32, 33. On pushing in the spindle 28, the plates 23, 24 engage in the channels 21, 22 and on rotation of the knob 30, the cam 31 exerts a downward pressure on the bracket 25 to ensure good contact between the channels 21, 22, and supply conductors 32, 33. Alternatively the plates 23, 24 may be arranged not to slide but the channels 21, 22 on the saucepan may be slid over the plates, which may be pulled down against the supply conductors 32, 33 by a cam 31 on bracket 25 fixed beneath. the plates, which may be readily removable for cleaning. The heat supplied may be varied by regulating the supply voltage, e.g. 0.7 to 1.2 volts by a variable choke or impedance, by a regulating resistance or by variable primary tappings on the transformer. The regulating resistance may comprise several superposed laminations 36 of hard copper or spring brass resting in a flat recess 35 in the supply conductor 33 and covered by a copper cover 37 mica lined at its inner sides. The channel member 22 on the saucepan rests on the copper cover 37 and resistance decreases or increases on downward pressure of the channel 22.

Abstract: 1434542 Switching circuits; directional switching WESTINGHOUSE BRAKE & SIGNAL CO Ltd 15 Jan 1974 [20 Jan 1973] 3029/73 Headings H3P and H4R A device for transferring information between two terminals INF1 and INF2 in either direction comprises two branches ICY1, ICX1 and ICY3, ICX2 each of which can be enabled to transfer information in a respective one of the two directions between the terminals and control means responsive to an input CON and to the first arriving information signal, to enable the appropriate branch to transfer the first arriving information signal and to inhibit the other branch until a predetermined time after the information signal has ceased. When no data is being transmitted lines INF1 and INF2 are at a logical "1" level and the circuit is enabled by application of a "0" on line CON. In this state points A, B, X, Y, M, N are at "1" and points W, L, P, Z are at "0". If INF1 changes to "0", W changes to "1", X changes to "0" and after a delay determined by the time constant of CX1, BX1 Y changes to "0" to change Z to "1" and B to "0". Thus the output at B follows the input at A with a delay determined by the time constant of CX1, RX1 and any inherent delay in the gates. A number of data sources may be selectively connected to a number of lines by means of a number of such devices selectively enabled by control signals at their CON inputs, Fig. 3 (not shown).
