Title: Improvements in printers
IPC: G06K15/08
Filed: 1963-10-21
Abstract: 991,658. Selective printing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Oct. 21, 1963 [Oct. 2, 1962], No. 41428/63. Heading B6F. [Also in Division G4] In a printer in which a plurality of type members move continuously and in a fixed sequence in front of an array of hammers, at least some of the characters are built up (printed) through overprinting of at least two type members. In the Figures a belt 11 holding two groups of 120 type members 10 is driven along the - length of a row of 144 hammers 13. Printing of one line of 144 characters using one group of 120 type members 10 is done in 360 subcycles. During each subcycle, every third hammer 13 has aligned with it one of a set of alternate type members 10, i.e. even and odd numbered type members 10 in even and odd-numbered subcycles respectively (Fig. 4, not shown). A magnetic drum M driven in synchronism with the belt 11 produces clock pulses. Some of the latter drive a character counter CC which produces in sequence during each subcycle parallelcoded representations of those type members that may, if required, be printed during the subcycle. Representations of the 144 characters required for a line are stored in a core matrix 14 (Fig. 1). During each sub-cycle, those representations corresponding to printing positions at which some character can be printed during the subcycle are read out sequentially into a one-character register 19 (through amplifiers 181 . . . 189) by means of an arrangement of AND-gates and three rings 28, 29, GR (Fig. 1) driven by clock pulses from drum M. The character in register 19 and that in character counter CC are compared (Fig. 3) by means of a comparator 42 and AND-gates 100, 103, 104, which by means of OR-gates 101, 102 provide, when appropriate, a signal to a hammer selection matrix 175 (Fig. 1) which consists of diode AND-gates and routes each signal to the appropriate hammer. These signals do not themselves actuate the hammers but are stored in corresponding thyratrons at 177 (Fig. 2) which then ensure that firing clock pulses from drum M reach the appropriate hammers 13. In Fig. 3, the AND-gates 103, 104 have inputs from register 19 and counter CC and are present to ensure the printing, when appropriate, of Japanese Katakana accents which are on different type members 10 from the bodies of Japanese characters. Reference has been directed by the Comptroller to Specification 919,653.
Patent GB-905155-A (GB)
Title: Improvements in or relating to voice-frequency transmission systems
IPC: H04Q1/446
Filed: 1958-12-23
Abstract: 905,155. Automatic exchange systems. WESTERN ELECTRIC CO. Inc. Dec. 23, 1958 [Dec. 24, 1957], No. 41431/58. Class 40 (4). In a voice frequency signalling system detection of the signalling current by a receiver at a tandem exchange causes a transistor to provide a low-impedance shunt across the forward speech path to prevent transmission of the signal to a subsequent exchange. In the Figure, in which an " X " indicates a make contact, and a vertical bar a break contact, the signal source 10 represents the receive pair of an incoming fourwire trunk line over which speech currents and pulses of 2600 c.p.s. signalling current may be received. In the absence of signalling current the voice currents are amplified by the pushpull complementary symmetry transistor amplifier VA, the output of which passes via transformer 30 to the outgoing trunk line 36. Incoming signals are applied via the secondary winding 14 of the input transformer 11 to an amplifier 38, which may be a transistor amplifier, and thence to a signal and guard detector 39. The latter whenever the guard-other than signalling-voltage predominates maintains the transistor 40 cut off, but when signalling current predominates causes transistor 40 to conduct. Saturation collector current then flows whereupon transistor 45 conducts and operates relay 53 which is followed by relay 55. Delay between the conduction of 40 and 45 may be provided by a circuit of the type described in Specification 904,749. Relay 55 grounds lead 54 to repeat the signal, introduces the bandelimination filter 18, 19, 20 and short-circuits winding 14 of the input transformer 11, thus preventing the transmission of signalling currents over the voice path and ensuring that the predominant frequency appearing across winding 18, and hence at the input of amplifier 38, is that of the signalling current. In order to prevent signalling current passing to the trunk line 36 prior to the operation of relay 55 it is arranged that the negative potential developed across resistor 44 as soon as transistor 40 conducts causes transistor 35 to conduct whereupon its collector-emitter path effectively shortcircuits the primary windings of transformer 30 to block the output of the voice amplifier VA immediately. On the operation of relay 55 the base of transistor 35 is grounded whereupon it is restored to its high collector-emitter impedance condition and the amplifier output is unblocked. Specification 729,261 also is referred to.

Abstract: 1419435 Impulse transmitters TELEPHONUND TELEGRAPHEN - FABRIKS AG KAPSCH & SOHNE IN WIEN 4 Sept 1973 [14 Sept 1972] 41495/73 Heading H4K In an impulse transmitter, the impulsing disc is driven during the return motion of the dial finger plate by means of a one-way clutch. The latter consists of a disc 3 which is fast to the finger plate spindle 1 and which has two dependent pegs 51, 52. During wind-up of the dial, peg 51 drives before it a finger like spring 6 which is loosely coupled to the spindle 1. The free end of the spring is deflected over projections 7 located around the periphery of the impulsing disc 8 so that the latter is not then driven. During the return motion, peg 52 drives the spring into engagement with a projection 7 thereby rotating the impulsing disc such that its castellations 9 actuate an impulsing contact. The spring is deflected by virtue of the shape of the projections 7 as shown or by virtue of its own flexibility (Fig. 6, not shown).

Abstract: Homopolymers of aziridines containing the recurring unit <FORM:1111827/C3/1> where n is 0 to 4 are obtained by polymerization of the appropriate N-allylaziridines in the presence of an acid or an acidic salt capable of opening the aziridine ring.  The polymers can be further reacted through the allylic groups to give cross-linked products.  Example 12 describes the polymerization of N-allylaziridine in the presence of dilute HCl.  Other specified monomers are N-methallyl- and N-ethallylaziridine.ALSO:N-allylaziridines are prepared by reacting at least one mole of an aziridine having a replaceable imino hydrogen atom with one mole of an allylic halide of the formula <FORM:1111827/C2/1> where R1-3 are hydrogen or C1-4 alkyl groups and X is Cl, Br or I, in a polar solvent and in at least 1 mol of a strong base per mol of allylic halide.  A polar solvent is defined as a solvent having a dielectric constant of at least 5 at 20 DEG  C., e.g. water, nitrobenzene, acetonitrile, dimethylformamide and lower alkanols. By a strong base is meant any base which can be used in the general reaction between a secondary amine and an alkyl halide, e.g. hydroxides, oxides and alkoxides of alkali metals, and alkaline earth metals, ammonina and tertiary amines.  Specified aziridines include those substituted on one or more carbon atoms by methyl, cyclohexyl, phenyl and benzyl groups.

Headings C3G and C3P. A random copolymer comprises units of acrylonitrile and units of at least one aromatic olefin in a molar ratio of acrylonitrile to aromatic olefin of between 2 and 6 and contains up to 10 mole per cent (where the sum of acrylonitrile and aromatic olefin units represents 100 mole per cent) of copolymerized units of at least one monomer selected from maleimide and its N- substituted derivatives and norbornene and its derivatives, including methylene norbornane. The aromatic olefin is, e.g. styrene or a substituted styrene, acenaphthylene, indene, coumarone, 1-vinyl naphthalene, 2-vinyl thiophene, 3-vinyl phenanthrene, 2-methyl-5-vinyl pyridine or N-vinyl carbazole. Preferred maleimides are N-aryl maleimides, e.g. N-phenyl or N-o-chlorophenyl maleimide. The copolymer is used in blends with graft copolymers such as polybutadiene grafted with acrylonitrile and isobutene or styrene. The copolymer is prepared by a process in which at least the aromatic olefin is fed into the reaction medium as the polymerization proceeds, at a rate determined by the heat evolved by the polymerization. In the examples, terpolymers of acrylonitrile and styrene with N-o-chlorophenyl maleimide, 5- cyanonorbomene, maleimide or methylene norbornane are prepared, as are terpolymers of acrylonitrile and alpha-methyl styrene with N- o-chlorophenyl maleimide or maleimide, by polymerization in an aqueous medium.
