Abstract: 1,261,277. Printed circuits. INTERNATIONAL BUSINESS MACHINES CORP. 1 Oct., 1969 [21 Oct., 1968], No. 48210/69. Heading H1R. [Also in Divisions C7 and G5] In making a printed circuit, a copper sheet 63 adhered to a dielectric substrate 64 is coated with polytetrafluoroethylene and the coating is subsequently removed from edge tab portions 66-71 which are to serve as terminals. The coating is applied by electrophoresis (see Abridgment Division C7) with the copper immersed in an aqueous colloidal electrolyte 77. After applying the coating the current is switched off, a holding member 72 is raised so that only edge tabs 67, 68 are immersed and a current is passed in the opposite direction from that used during coating, so as to remove coating material from the tabs. The holding member is rotated through steps of 90 degrees and the coating material, before it has dried on the tabs, is similarly removed from the tabs at each edge in turn.

Abstract: 1363738 Protective arrangements; control of A.C. motors KOMBINAT VEB MESSGERATEWERK ZWONITZ GERATEWERK KARLMARX-STADT 25 Oct 1971 49508/71 Headings' H2J and H2K A protective arrangement for a motor M, e.g. of a teleprinter, comprises first means W1 responsive to the temperature of the motor, second means G, L responsive to the speed of the motor, and third means operative on response of the first and/or second means to break the supply circuit to the motor in the event of high temperature or low speed. As shown, the first means W1 is a positive temperature coefficient resistor inside the motor and connected in series with a transistor T1 across a capacitor C2. A device G driven by the motor induces pulses in a coil L connected to the base of the transistor T1. When the temperature is high or the speed is low, the average conduction of the transistor is low, so that the capacitor C2 charges until a Zener diode D2 breaks down causing a transistor T2 to conduct and energize a relay X. The relay X opens its contacts x to cause a switching apparatus F to effect disconnection from a telegraph line a, b and the operation of a relay Y which opens its contacts y1 to disconnect the motor M.

Title: Rotary fluid pump or motor
IPC: F04C5/00
Filed: 1965-11-22
Abstract: 1,112,264. Rotary pumps and motors. J. VANSTEENE. Nov. 22, 1965 [Nov. 20, 1964], No. 49542/65. Heading F1F. A rotary hydraulic or pneumatic pump or motor of the gyratory rotor type, comprises a cylindrical stator 1, Fig. 1, within which a rotor 2 rotatable about its own axis a in one direction is constrained to rotate about the axis A of the stator in the opposite direction by means of rotatable cheekplates (not shown) on which the rotor is carried and a mechanical drive. A flexible substantially inextensible strip 3, connected at one end to the stator and at its other end to the rotor is sealed at its edges between the cheek-plates to define with the cheek-plates, stator and rotor a chamber C which cyclically increases and decreases in volume as the rotor rotates. In operation as a motor, admittance of pressure fluid to the chamber C causes a tension T in the strip 3 to generate an anticlockwise moment TR on the rotor 2 which is resisted by a clockwise moment Tr to develop a motive couple, neglecting friction of T(R-r) on an output shaft, where r and R are the radii of the rotor and rotor orbit respectively. As shown in Fig. 6, a hollow rotor 12 is rotatably mounted in cheek-plates 17 which are in turn rotatably mounted in a stator 11 and a strip 13 sealingly engaging at its edges the cheek-plates is connected to the stator and rotor to define a chamber C to which fluid is admitted to and discharged from through ports 14, 15 in the hollow rotor. The mechanical drive causing the rotor to rotate about its own axis in one direction and the axis of the stator in the opposite direction comprises sprockets 20, 21 fixed to the rotor 12 and stator 11 respectively and a sprocket chain 19. Gearing or any other suitable drive could be used. A practical construction of the invention is described with reference to Figs. 7 to 10 (not shown). In this construction, the rotor is mounted on two eccentric bearings to permit movement of the rotor towards or away from the internal surface of the stator. In a modification, Fig. 5 (not shown), three strips are anchored to the stator and rotor at spaced apart angular positions to define three chambers to which fluid is sequentially admitted to and discharged from to produce a more regular motive couple or more regular pump output. One cheek-plate may be made relatively displaceable with respect to the other to take up wear. It is stated that the device may operate as an I. C. engine. The strips may be covered with material such as tetra fluoroethylene to mitigate against friction and ensure sealing between the strips and the cheek-plates.

Abstract: 1337056 Digital transmission system INTERNATIONAL BUSINESS MACHINES CORP 27 Oct 1971 [29 Oct 1970] 49817/71 Heading H4P In a data transmission system where an information element is represented by a signal element, such as of the form  (sin x)/x cos w c <SP>t</SP> and  (sin x)/x sin w c <SP>t</SP> described in Specification 1,314,875 and signal elements from successive or groups of information elements are combined to form for example a phase modulated signal representing the information elements, digitally encoded representations of the possible signal elements are contained in a store (e.g. read-only) and in response to the information elements to be transmitted are read out, to be used to form the signal for transmission. Fig. 6 shows an arrangement for generating an 8-phase delta modulated signal, where digital representations of eight signal elements are contained in a store 10. Incoming binary data E is grouped into groups of 3 bits and coded according to the Gray code giving 3-bit signals. An addressing device 12 contains in register 20 the latest 3-bit signal and in the 5 stage register 21 the previous five 3-bit signals. As there are six signal elements to be combined each of length 6T, but each staggered by an interval T to the adjacent one, addressing device 12 reads out bit by bit from store 10 a different interval T for each stored signal element corresponding to the addresses contained in registers 20 and 21. Accordingly counter 24 holds the count representing the bit in any interval T currently being read and counter 23 the interval T of the signal element being read. The contents of the register 20 and stages 2-6 of register 21 are recirculated via AND gate A2 and at each step counter 23 is increased by 1 thereby causing the read out of the correct interval T of each address as it appears in the register 20. After one circulation a fresh 3-bit signal is placed in register 20 from adding circuit 22 and the last address or 3-bit signal in stage 6 is erased, counter 24 is increased by 1 and a cycle repeats. The bits read out of the store from one circulation of registers 20 and 21 enter register 25 and are read out via gates 26 in parallel to a further register 27 from which an analogue signal is derived via resistors R. Adding circuit 22 actually adds each fresh 3-bit signal to the 3-bit signal found in register 20 thereby giving rise to delta modulation, which modulation is removed from the final analogue signal before transmission.
