Title: Graft copolymers of certain monomeric sulphonic acids on polyvinyl lactams and improved acrylonitrile polymer compositions obtainable therewith
IPC: C08F271/02
Filed: 1958-11-04
Abstract: Graft copolymers are prepared by polymerising between 10 and 80% by weight, based on the resulting graft copolymer, of an alkenyl group containing organic sulphonic acid and between 90 and 20% of a vinyl lactam polymer, the alkenyl sulphonic acid being selected from those having the formulae:  (aromatic vinylidene sulphonic acids) <FORM:0849063/IV(a)/1> wherein X is hydrogen, C1-C4 aliphatic hydrocarbon radicals or alkali metal ions; Y is hydrogen, chlorine or bromine; R is methyl or ethyl; Z is hydrogen or methyl; m is an integer of from 0 to 2; n is 1 or 2; p is 0 or 1 and r has a numerical value from 1 to 4.  The sulphonic monomers may be used alone or in admixture with methylenebisacrylamide or methylenebismethacrylamide.  Preferred vinyl lactam polymers are polyvinyl pyrrolidone, poly-N-vinyl-5-methyl-2-pyrrolidone, poly-N-vinyl caprolactam and poly-N-vinyl piperidone. Polymerisation may be effected in aqueous or organic solution with the aid of hydrogen peroxide, persulphates, organic peroxides or azo compounds as catalysts.  Polymerisation may also be effected by means of high energy irradiation.  The graft copolymers may be used as additives to polymers containing at least 80% of acrylonitrile, the resulting compositions containing up to 20% of the graft copolymer.  The graft copolymer may be incorporated in the acrylonitrile polymer prior to a shaping operation or fibres of the acrylonitrile polymer is aquagel form may be passed through an impregnating bath containing dissolved graft copolymer, e.g. in the manner described in Specification 758,937.  The addition of the graft copolymer confers dyeability, stability, and anti-static properties upon fibres made from the acrylonitrile polymer.

Patent GB-1412992-A (GB)
Title: Telephone exchanges
IPC: H04Q3/62
Filed: 1972-08-01
Abstract: 1412992 Automatic exchange systems STANDARD TELEPHONES & CABLES Ltd 24 July 1973 [1 Aug 1972] 35798/72 Heading H4K In order to trace a malicious call incoming to a PBX from a parent exchange, an operator actuates a special key which causes a signal to be transmitted to the parent exchange whereat a holding loop is placed across the callers' sides of the transmission bridges on all the final selectors which are currently active with calls between the two exchanges. Arrangements are also provided for tracing malicious internal calls which utilise operator assistance relay sets. When an operator becomes aware of the existence of a malicious external call she actuates her key MK to the lower position so as to bring-up relay A. The latter applies alarm battery over both sides of a special signal wire extending to the public exchange and pulls up a relay AA which is turn signals the local police station and energizes alarm buzzers BM and BZA in the PBX's, manager's and security offices. At the main exchange the appearance of alarm battery causes relays XA, XB to connect a holding coil IAF across the callers' sides of the transmission bridges of all the currently busy PBX final selectors. A main exchange alarm is energized so as to alert an engineer. He finds the relevant final selector by talking thereover to the operator or by listening for a warning tone applied thereto from a special extension at the PBX (the operator having connected the malicious calling junction through to this extension by operating relay D). Once the final selector is found subsequent call tracing can be effected in any known way. On an internal call, the operator causes relay C to switch looping coils DA1-DA4 across the callers' sides of the local operator assistance relay sets. The location of the relevant set and subsequent tracing are effected by a PBX engineer in this case. All the alarms, except that to the main exchange, are initiated as before. The manager and a security office may be equipped with similar call trace keys KB, KS.

IPC: G05F1/56
Filed: 1960-10-19
Abstract: 913,130. Automatic voltage-control. GREILLER, R., and KUPPERS, K. Oct. 19, 1960 [Oct. 30, 1959], No. 35870/60. Class 38 (4). A regulating circuit for D.C. systems comprises a plurality of sources connected in series for providing the input voltage, a regulating transistor connected in series or parallel with one of the said sources supplying a voltage smaller than the permissible collector-emitter voltage of the regulating transistor, and a switch connected in parallel with the said series or parallel circuit, the arrangement being such that the switch closes on overload so that the transistor is not subjected to a destructive over-voltage from the other input voltage sources. As shown, a transistor 3 is connected in series with the load and with a source 1 supplying on unregulated voltage U 1 , the total input voltage U 3  comprising voltage U 1  and a voltage U 2  supplied from a source 2 connected in series with the source 1. A switch 4 is connected in parallel with the series circuit of transistor 3 and source 1. The output voltage U 4  is compared with a reference source, e.g. a Zener diode, in a discriminator 6, any resulting error signal being applied over an amplifier 5 to the base of transistor 3 the conductance of which is thereby varied so that U 4  is maintained constant. On overload, switch 4 closes so that voltage U 2  is prevented from being applied to the transistor 3 which is thereby protected; at the same time a resulting signal from amplifier 5 is arranged to bias the transistor 3 to cut-off. The switch 4 may be a silicon diode arranged to become conducting when the output voltage decreases, because of overloading, below the potential of voltage source 2. A regulating system of the shunt transistor type is also described (Fig. 3, not shown).

Title: Improvements relating to locking means for detachable covers for box-like enclosuresfor electrical equipment and components
IPC: E05B65/00
Filed: 1959-10-23
Abstract: 936,389. Conduits. N. W. HUSLER. Jan. 23, 1961 [Oct. 23, 1959], No. 35912/59. Class 36. [Also in Group XXV] A cover 15 is locked to channel-shaped trunking by a turnable locking member 10 secured to a nut 12 which runs on a screw 14 passed through a suitable hole in the cover. A split ring locking nut 13 fastened to the nut 12 ensures that there is sufficient resistance that on initial rotation of the screw the locking member will rotate to its locked position in which its obliquely cut ends fit beneath inturned flanges 111 on the trunking, further rotation of the member being prevented by the contact of its corners with the side walls of the trunking. Further rotation of the screw merely moves the nut along the screw and tightly secures the cover. In a further embodiment, Figs. 4 and 5 (not shown), the locking member projects from only one side of its pivot, a spacing member being placed between the member and its cover to prevent it from tilting when tightened under the trunking flange. While the additional locking nut 13 is not essential its presence is preferable to ensure sufficient resistance to rotate the member to its locked position. In the absence of nut 13 the nut attached to the locking member may be replaced by a tapped hole provided therein. The locking device may also be used to hold covers on other similar enclosures, particularly those for electrical equipment.
