Abstract: 1,213,007. Selective printers. OLYMPIA WERKE A.G. 30 Nov., 1967 [9 Feb., 1967], No. 54663/67. Heading B6F. A selective printer associated with a dataprocessing machine comprises a stationary, laterally open housing 9 in which is journalled a shaft 1 supporting by means of radial, diametrally opposite pins 2, 3 a plurality of concentric, axially spaced type carriers 8 each provided with a planetary gear 8c. The gear 8c meshes with a stationary sun gear 9a when a released pin 2 displaces a selected type carrier 8 radially towards the housing 9, thereby continued angular displacement of the pin 2 by the rotating shaft 1 causes the pin to become disengaged from its detent notch 8b and ride over an adjacent cam surface 8a to induce a hypercycloidal impression movement of the type carrier 8 against a recording medium' 13 supported on a platen at a printing station D. The selection of characters is effected by radially inward pivotal displacement of respective control levers 11 in response of a data control signal released at a predetermined time corresponding to the character to be selected. The control levers 11 have each a plurality of lugs 11a a selected one of which engages a stop 10b associated with a detent ring 10, one for each type carrier 8 so as to disengage a detent (10a, Fig. 1) from a notch (2a) in the radial pin 2 which in consequence thereof is displaced radially outwardly by the torsion springs 4, 5 to connect the planetary gear 8c drivingly to the sun gear 9a. When the pin 2 has been displaced angularly through 180 degrees along the cam surface 8a it abuts again a detent notch 8b at which time the type carrier 8 is disposed concentrically with respect to the shaft 1 and reset to its rest position.  Machines with dual sets of types.-The type carrier is provided with two identical, diametrally opposite sets of types which are selected successively during rotation of the shaft 1 by timed operation of the control lever 11. Type-wheel construction.-The type carriers 8 are of annular construction and provided along their radially inner periphery with two diametrally opposite cam surfaces 8a separated from each other by detent notches 8b, which in conjunction with the radial pins 2 serve for maintaining the type carriers in a concentric disposition relative to the shaft 1. Each type carrier is associated integrally with a planetary gear 8c.

Title: Intercommunication systems
IPC: H04M9/00
Filed: 1971-12-09
Abstract: 1382990 Communication systems; multiplex pulse signalling, gating circuits J H KNOX 5 Dec 1972 [9 Dec 1971] 57141/71 Headings H3T H4L and H4K A system for communicating between a number of acoustic transducers comprises a gate associated with each transducer and passing signals only if they are in a given amplitude range the position of the range being determined by an applied bias voltage mission Thus if each gate has a different bias normally applied to it, communication can be established to a selected one by adding to the signal transmitted to it a bias which brings the signal to within the range of that gate. Arrangements are described for paging and for multiplexing. Fig. 4 shows one terminal including a gate comprising two diodes 12, 35, a current bias sink transistor 24 and a voltage biasing transistor 23 having its base normally connected to a bias resistor tap by a switch 48. In the normal bias condition the gate will pass signals received on line 30 only if they are accompanied by a bias equal to the normal bias and these signals will pass through capacitor 42 and amplifier 43 to the receiving device 49. To respond, the receiving terminal, asks the distant terminal to identify his channel and then operates a switch 46 to correspond with the bias of that channel. One level of the switch operates contact 40 to by-pass the gate so as to connect this bias to line 30. Another level of the switch changes over contacts 44 and 45 so that the output of the transmitter 49 is connected through amplifier 43 to the line. One terminal for example, that at the front door of a residence, utilizes the lowest bias condition so that by operating biasing switch 50 any station may listen to the front door terminal. The arrangement also includes a paging gate 36 at each terminal operated at the highest bias level so that any station can apply, by a contact 46, the high level to the line and thus open the paging gates at the other terminals. Alternatively, paging may be effected by sweeping the bias over its range at a supersonic rate so that all gates are opened. Means may be provided to indicate that the line is in use. An alternative gate is shown in Fig. 7. Input signals are applied to the base of transistor 71 and are transmitted via capacitor 76 and outgoing signals are applied through capacitor 74 to transistor 72, contact 73 being made so that the bias level selected is also transmitted to the line. Fig. 6 shows a terminal adapted for a multiplexing arrangement. In this arrangement the bias of line 30 is swept at a supersonic frequency over the range and connection between terminals is effected by biasing both terminals to the same level. The output of the circuit includes a filter 52 for the sweeping frequency and paging is provided by short-circuiting the gate via a capacitor 53.

Abstract: 1299400 Graft polymer compositions SHINETSU CHEMICAL CO 29 Dec 1970 [30 Dec 1969] 61660/70 Heading C3G A method of preparing vinyl chloride resin compositions comprises: (1) conducting polymerization in a polymerization vessel, containing an aqueous emulsion and having two inlets, by continuously pouring into the vessel 10-90 parts by weight of a diene rubber polymer, through one of the inlets, and 90-10 parts by weight complementarily of methyl methacrylate and 5-180 parts by weight of styrene through the other inlet, from 20 to 80% of the methyl methacrylate being added first, on its own, and the remainder of the methyl methacrylate being added subsequently mixed with the styrene, (2) recovering the graft polymer thus obtained from the aqueous emulsion, and (3) adding 30-1 parts by weight of the graft polymer with agitation to 70-99 parts by weight of vinyl chloride resin. The diene rubber polymer may be polybutadiene or a butadiene-styrene copolymer prepared by copolymerizing a mixture comprising styrene and at least 50% of butadiene. The polymerization may be carried out at 40-70‹ C. for 2-10 hours in the presence of a known polymerization catalyst, such as a redox catalyst of a peroxide such as cumene hydroperoxide or diisopropylbenzoyl peroxide and an iron salt such as ferrous sulphate. The amount of aqueous emulsion used in the first step is preferably such that the concentration. of the graft polymer product in the reaction liquid is 40-50% by weight and the aqueous emulsion may be prepared by adding 0À1-10 parts by weight of an emulsifier to 100 parts by weight of water. The emulsifier may be disproportionated rosin soap, tetrahydroabietic soap, dextropimaric soap or lauryl soap. The graft polymer is recovered by being salted out, filtered off and dried. The vinyl chloride resin may be vinyl chloride homopolymer and copolymers of vinyl chloride and a copolymerizable ethylenically unsaturated monomer, such as vinyl acetate, acrylonitrile, vinylidene chloride, vinyl ether or an α-olefin, and comprising at least 80% of vinyl chloride units. The vinyl chloride resin preferably has a polymerization degree of 600 to 1300. The amount of styrene added in admixture with the methyl methacrylate is 0À5-2 times the total amount of methyl methacrylate used.

Abstract: 1,268,559. Transistor switching circuits. ROBERT BOSCH G.m.b.H. 19 Dec., 1969 [21 Dec., 1968; 10 Jan., 1969], No. 61883/69. Heading H3T. [Also in Divisions G3 and H2] A two terminal transistor circuit 21, Fig. 1 (Figs. 2, 3 or 4, not shown) forms part of a voltage regulator and responds to an excessive voltage across it, such as the rectified output on lines 17, 22, of a generator 10, by changing its impedance from a high value to an irreversibly low value such as by destructive shortcircuiting of the transistor. The generator output is controlled in normal operation by successive switching on and off of the field current in winding 14 by a bi-stable circuit 39. A transistor 33 therein is normally off and holds a transistor 34 on to energize the winding 14. When the rectified generator output on line 22 rises sufficiently a Zener diode 32 conducts and turns T33 on and T34 goes off, reciprocal coupling being effected through R37. De-energizing the field winding 14 causes the generator output to fall and the bi-stable eventually resets, the cycle repeating ten or more times per second. If due to a failure, the output voltage continues to rise uncontrolled, the two terminal circuit 21 shorts the lines 22, 17 and thereby collapses the output and the field voltages. The circuit 21 may consist of a transistor (47, Fig. 2, not shown) held off by a resistor 48 between base and emitter. Alternatively it may include a complementary pair of transistors (Figs. 3, 4, not shown) each having its main current path in the control circuit of the other; and a Zener diode (149, 249) across the collector and emitter of one in series with a resistor (147, 247) across the base emitter of the other, the Zener diode and resistor being connected to the two terminals of the circuit. A capacitor is provided to prevent transients from operating the circuit. In all three embodiments excessive voltage produces breakdown of the transistor and ultimate destruction. The circuits of Figs. 2, 3, 4 (not shown) may involve integrated circuit technique.
