Title: Improvements in or relating to bonding natural or synthetic rubber
IPC: C08J7/12
Filed: 1954-06-09
Abstract: Unvulcanized or vulcanized natural or synthetic rubber is bonded to a similar or other material by producing active hydrogen atoms, by means of an inorganic or organic oxidizing agent, in the rubber and then treating the rubber surface with a di- or polyisocyanate, unless one of the materials to be bonded contains free isocyanate groups, in which case the surface treatment may be dispensed with.  The inorganic agent is selected from: an acid anhydride, Caro's acid, hydrogen peroxide, sodium chlorite or hypochlorite, bleaching powder, potassium permanganate, chromic acid, potassium chlorate, and perchloric acid.  The organic agent is selected from organic per-acids, hydroperoxides and peroxides. The bonding may take place under heat and pressure.  A catalyst, e.g., quinhydrone, osmium tetroxide or peroxide, may be used, and a wetting agent may be added to the oxidizing agent.  The surface of the treated rubber may be coated with a saponifying agent, e.g., ammonia, water vapour or an amine, to effect a stronger bond.  In an example woven glass material is immersed in the following composition (parts by weight): latex 100, zinc oxide 5, colloidal silicic acid 20, benzine 375, to which is added 10 per cent of a 25 per cent peracetic acid solution and shortly before use 10 per cent of a solution of 2, 4-toluelenediisocyanate.

Title: Circuit arrangement for simultaneous signalling in both transmission directions between two terminal stations in telecommunication systems
IPC: H04Q1/38
Filed: 1967-07-14
Abstract: 1,134,371. Data transmission systems. INTERNATIONAL STANDARD ELECTRIC CORP. 14 July, 1967 [14 July, 1966; 11 March, 1967], No. 32460/67. Heading H4P. An electrical signalling system comprises two stations connected by a two-wire line for simultaneous two-way communication, and each station includes a transmitter which applies multi-state signals to the line, a number of receivers each of which provides an output which depends on the current or voltage condition of the line, and a unit which is fed both by the receivers and by the transmitter to determine the signals sent by the transmitter at the other station. In a first embodiment, Fig. 5, line Ltg connects similar stations A, B. Each station transmits binary single current signals by way of relay Sa (station A) which connects voltage Ua across the line. A relay REa has two windings connected as shown. Thus, if Sa (or Sb) is energized and Sb (or Sa) is not, relays REa and REb are both energized, whereas if both Sa and Sb are energized neither REa nor REb is energized. Units La, Lb are respectively controlled both by the transmitter Sa, Sb and by the relays REa, REb, and is such that point C is earthed if a signal has been received from the other station. Double current signalling may be used. In a second embodiment, Fig. 6, also for binary signalling, both stations, e.g. station B, comprise a transmitter relay Sb which applies earth or - U to the line. The receiver comprises a pair of voltage dividers T1, T2 of like ratio, comprising resistors R1, R2 and R1<SP>1</SP>, R2<SP>1</SP>. The voltage applied to T2 depends on Sb. Threshold unit AE is connected to the taps on the dividers and in effect compares the line voltage with a threshold voltage which depends on the position of contact Sb1 i.e. upon the data element transmitted. Unit AE thus gives one polarity output if the other station is transmitting and the opposite polarity if it is not. A station comprising a transmitter for three level signals is described, Fig. 10 (not shown). It is similar to that of Fig. 6 but has two transmitting relays and two pairs of voltage dividers with associated threshold units. Since the latter have switched threshold voltages, as in Fig. 6, there are in effect four thresholds. The threshold units provide signals to a gate arrangement which determines which signal has been transmitted from the other station.

Filed: 1959-09-24
Abstract: 858,998. Preparation of fritted bodies. ZEISS-STIFTUNG, C., [trading as JENAER GLASWERK SCHOTT & GEN.]. Sept. 24, 1959 [Sept. 25, 1958], No. 32561/59. Class 56. [Also in Group XXVIII] In the production of a fritted body from vitreous granules, the granules are comminuted in a roller mill before sintering the finely divided material. The gap between the rolls is preferably adjustable. The resultant grains after grinding in a roller mill are of splinterlike form instead of spherical form a ball mill and they have a larger external surface area. When used for filter elements, they therefore give a larger internal surface area. Shorter firing times are needed and less risk of shrinkage and fire cracks.

Title: Improved high speed logic circuit device
IPC: H03K19/086
Filed: 1969-06-27
Abstract: 1,245,347. Semi-conductor logic circuits. NIPPON TELEGRAPH & TELEPHONE PUBLIC CORP. 27 June, 1969 [1 July, 1968; 5 July, 1968; 21 Sept., 1968], No. 32589/69. Heading H3T. A logic device includes an emitter-coupled low amplitude logic circuit 1 operating from a voltage supply on lines 11-9, and handling logic signals less than 1V BE , and a high level logic circuit (which may also be emitter coupled) 2 operating from a higher voltage supply on lines 11-20 to handle a larger logic amplitude, and also includes converting circuits 3, 4 which shift the signal levels and change their logic swing amplitudes in order to link the high and low level logic circuits 1, 2. The collector and emitter resistors of the low level circuit 1 are selected to give a logic swing of the order of ¢V BE  and the voltage supply 11-9 is made large enough only to supply this voltage plus the transistor voltage. Such low values are possible with acceptable noise levels when several low level circuits and their interconnections are integrated in the same chip. The higher level circuit is used when longer interconnections are necessary as between different chips or parts of a printed circuit arrangement. The logic swing of the high level circuit is 1V BE , and the changes of swing are effected by choice of the emitter resistor and output collector resistor of the converting circuits 3, 4. Level shifting is achieved by emitter followers such as 31, 19, and the reference voltages for the various emitter coupled circuits are appropriately changed such as by a diode 16 or a transistor 24. Such use of p-n junctions to change the reference levels affords temperature compensation and matching between the circuits. In various modifications, the voltage supply 11-9 to the low level circuit 1 is made dependent on temperature by a circuit (34, Fig. 2, not shown) which thus compensates for temperature effects in the low level circuit, and a level shifting transistor is included in the input of the high level circuit (2) instead of in the converter. In one of the level converting circuits (3, Fig. 3, not shown) temperature compensation of the reference voltage applied to one base of the e-c pair is effected by a transistor (52) whose collector, base and emitter are respectively connected to one end, the junction and the other end of two series resistors forming part of a divider across the supply. A push-pull drive from the collectors of both transistors (63, 64, Fig. 5, not shown) of a high level circuit control two series connected transistors (67, 68) whose interconnection forms the output for a capacitive load. Multi-emitter transistors may be used as the input to the low level circuit (Figs. 5, 6, not shown).
