Patent GB-1253499-A (GB)
Title: Alarm system
IPC: G08B17/06
Filed: 1970-03-11
Abstract: 1,253,499. Alarm system. WESTINGHOUSE ELECTRIC CORP. 11 March, 1970 [2 April, 1969], No. 11659/70. Heading G4N. A fire alarm system has means for detecting power supply failure and breaks in continuity in the alarm detecting loop, the alarm bell loop and the fault detecting loop, stand by circuits are arranged so that the alarm will still be activated by a fire despite the presence of a fault condition. Three power supplies V 1 -V 3  are provided, all three are fed to circuit AC1 which selects the highest voltages, and only two to circuit AC2. This ensures that the supply V 2  is always available to operate the alarm. If any one of the supplies fails circuit VS is activated and causes a failure indicator to operate. If a continuity break occurs in the alarm initiation loop A1L or its connection to the alarm circuit A or the connection between the alarm bell loop, the continuity supervision circuit is activated to give a fault indication and alternative connections (dotted lines) are provided between the units. In addition if a continuity break occurs in the auxiliary alarm AA, or in fault detection circuits ATB or ATA; a fault indication is given. Further should a drop in resistance across the normally open alarm elements occur e.g. due to condensation, a fault indication is again given. U.S. Specification 3,098,253 referred to.

Title: Radio detection of moving objects
IPC: G01S13/58
Filed: 1959-04-07
Abstract: 900,778. Radar. CANADA, MINISTER OF NATIONAL DEFENCE. April 7, 1959 [Dec. 29, 1958], No. 11767/59. Class 40 (7). Relates to the detection of targets with high acceleration, e.g. earth satellites and meteors by C. W. Doppler radar. According to the invention the receiver output is applied to a bank of band-pass filters 15 which feed a matrix 16 wherein each filter output is multiplied by a predetermined factor and the multiplied signals are added to form an output from which an alarm is actuated. It is stated that this avoids the use of a large number of filters necessary in known systems to give an equivalent result, Figs. 2 and 3 (neither shown). In a further embodiment the receiver coherent local oscillator (L.O.) is controlled in frequency by the matrix output to effectively decrease the rate of change of Doppler beat frequency and several L.O./filter/matrix combinations are used; a L.O. frequency may be controlled according to a predetermined law corresponding to an expected target acceleration, Fig. 5 (not shown).

Abstract: 1385352 Carbon fibre resin compositions COMMISSARIAT A L'ENERGIE ATOMIQUE 15 March 1972 [19 March 1971] 11983/72 Heading C1A [Also in Division C3] A composite material comprising carbon fibres and resin is prepared by (a) treating carbon fibres with a graft or block copolymer to form chemical bonds between the carbon fibres and the copolymer, and (b) incorporating the treated fibres in a resin, the block or graft copolymer comprising a first type of sequence (A) which forms the chemical bonds with the fibres and is incompatible with the resin, and a second type of sequence (B) which is compatible with the resin. In a modification step (a) comprises forming chemical bonds between the carbon fibres and a polymer of sequence A, and grafting polymer of sequence B on to the polymer of sequence A. Sequence A may be bonded by covalent bonds formed by radical grafting or anionic grafting, or by ionic bonds, e.g. hydrogen bonds, dipole-dipole bonds or saline bonds. Sequence B may be grafted on sequence A by means of covalent bonds or ionic bonds. In the examples carbon fibres are oxidized by ozone, treated with sodium hydroxide, acidified with HCl, washed with distilled water, dried and salified with sodium methanolate in the presence of phenol-phthalein and then immersed in solutions of a block copolymer which had previously been salified with sodium methanolate (poly- (carboxylated) isoprene-b-styrene-co-maleic anhydride), pure polyisoprene-maleic anhydridestyrene block copolymer in the carboxylated state, a carboxylated, crude graft polyisoprenemaleic anhydride-styrene copolymer and a non- carboxylated polyisoprene-maleic anhydridestyrene graft copolymer which had been salified with NaOH. In Example 6 a carboxylated polybutadiene is bonded to carbon fibres which have been preoxidized in air and then maleic anhydride-styrene copolymer is grafted on to the polybutadiene in the presence of benzoyl peroxide and benzene. The treated fibres are incorporated into an epoxy resin.

[Class 44.] A latch 15 cut from a strip of extruded brass, &c. is shot by a spring 20 of U, S, double S or safety pin form having one limb 29 engaging with an undercut shoulder 19 on the bolt and another limb 30 engaging with one side 11 of the latch casing, which is preferably bent up from a sheet-metal blank, the spring being arranged between the bolt 15 and the front 10 of the casing. The bolt may be operated by a handle 24 integral therewith and projecting from the wall 11 of the casing or by a handle 33 attached thereto and slidable in a slot 32 in the front 10 of the casing. A tongue 27 cut out of the casing to form an aperture 16 through which the bolt slides may be bent back to form a guide for the bolt. One or more ribs 23 may be formed on the bolt to limit its movement and the head 25 may be bevelled on one or both sides. In the form shown in Fig. 7, the spring is distorted laterally so as to hold the bolt against the front 10 of the casing.

IPC: C07K16/30
Filed: 1927-05-06
Abstract: 300,144. Glover, T. J. May 6, 1927. Antitoxins, ioxins, vaccines, and like serums; bacteria, cultivating.-Cancer organisms, the cultural and morphological characteristics of which are described, are prepared from cancerous tissue by making a primary culture in a medium consisting of decoctions of sunflower seed, Iceland moss, and Irish moss, peptone, hormone gelatine broth, and glucose, with or without agar, the PH being adjusted to about 6.5. The hormone gelatine broth is prepared from eggs, beef heart, peptone, sodium chloride, aminoids (digested beef heart), gelatine and dextrose. Toxin is prepared by further cultivating organisms, which have been repeatedly subcultivated in the original medium, in a similar medium but without serum, sugar, or agar. This culture is filtered through Buchner and Berkefeld filters, a small quantity of phenol is added, and the toxin standardized. The toxin may be greatly diluted for use in skin tests to determine susceptibility to, or presence of, cancer, or may be injected over a long period into a horse to obtain antitoxic serum, which is refined and concentrated by the Gibson and Banzhbf method (details of which are given in the Specification) whereby proteins such as euglobulin and albumin are removed. Preferably a preliminary injection of antitoxin is employed before injecting the horse with toxin. A test for the organisms by using them to produce tumours in animals, and agglutination and precipitation tests, are also described.

Abstract: 805,836. Cutting plastic materials. ALKETT MASCHINENBAU G.m.b.H. [formerly ALKETT ALTMARKISCHE KETTENWERKE G.m.b.H.]. April 29, 1955 [March 31, 1955], No. 12375/55. Class 87(2). A body 93 of foamed plastic material may be cut in a zig-zag form by one or more hot wires 81 which are reciprocated by a rack and pinion 83, 84 driven by a reversible motor 88 controlled by contacts 90, 91. A castellated pattern may be formed, Fig, 2, (not shown) by allowing the contacts 90, 91 to control the drive of the conveyer 92 in such a manner that it moves intermittently, and also providing an electro. magnetic coupling to cause the wires to move intermittently. In the construction shown in Fig. 3, the body 93 may be pared in circular or spiral form by a wire 81 which is rotated about an axis M-M by a drive from a motor 88. For irregular curves the course of the wire may be determined by a template, Fig. 5, (not shown). In a further modification, Fig. 8, the wire 81 is moved vertically in response to signals from a template which control the motor 132, whilst signals from a further template control a motor 133 which drives a conveyer 92 carrying the body 93, thus cutting out a desired shape. Gases produced by the hot wire may be removed by suction, to prevent material from deing deposited on the wire. To assist in keeping the wires clean, nitrogen may be blown into the cutting region. The body may be driven by spiked rollers instead of endless bands.
