Abstract: 610,307. Lead-in attachments for electric switches and valves. CIANCHI, A. L. March 24, 1944, No. 5540. [Class 36] [Also in Group XXXVII] The lead-in elements of an electric switch or valve which pass through a porcelain or like ceramic wall-portion are secured to the latter by small glass seals, the thermal expansibility of the ceramic and glass being substantially the same as that of the conductors. The glass seal may be applied as powder or paste; or, as a prefabricated ring. Fig. 1 shows a switch comprising fixed and movable contacts 1, 3, the latter being mounted on a spring lead-in wire 4 which carries an armature 5 for cooperation with a movable external magnet 11. The tubular casing 6 is of porcelain with a similar end-closure 7 through which the lead-in 4 passes, glass seals 9, 10 being provided around the wire 4 and the edge of the closure 7. A similar seal 8 is provided for the fixed lead-in 2. Fig. 4 shows a modified form of switch comprising a ceramic float 16 dipping into mercury in the casing 14, the position of the float being controlled by an electro-magnet 20 which co-operates with an armature-collar on the float. When the magnet is energized to lower the float, mercury enters through apertures 16<1> to close the circuit between the electrodes 15, 18 around which glass seals 15<1>, 18<1> are provided.

Filed: 1977-02-14
Abstract: 1516813 Charge transfer device THOMSONCSF 14 Feb 1977 [17 Feb 1976] 06136/77 Heading H3U A charge transfer device having an input device comprising a diode D e  and a gate G e  is fed with input signals in the form of pulses which are synchronized with one of the clock signals #, and which are width modulated in accordance with the input data to be transferred through the charge transfer device. The diode D e , gate G e  and layer I constitute a field effect transistor, and if the amplitude of the input pulses is sufficient, the current through the transistor is constant and the input charge is accordingly proportional to time, i.e. to the duration of the input pulses. Thus the signal transferred is linearly related to the input signal which width modulates the pulses.

Title: Linear polyurea derivatives
IPC: C08L75/02
Filed: 1950-03-13
Abstract: In making linear polyureas, a diamine of the general formula X.HN-R-NH2, in which X is a methyl group and R an organic group with at least 6 carbon atoms, or X is a hydrogen atom and R an aliphatic group with at least 7 carbon atoms or a non-aliphatic group having at least 4 carbon atoms, or a mixture of two or more of the above diamines or a mixture of one of the above diamines with a diamine of the above formula, but wherein R is an aliphatic group of 4 to 6 carbon atoms and X is hydrogen, is reacted with carbon oxysulphide (COS) to form a polymonothiocarbamate and the latter is heated for such time and to such a temperature that a substantially sulphur-free polyurea derivative is obtained. Diamines specified are: 1.8-diamino octane, 1.10-diamino decane, meta- and para - diamino - benzene, p - p1 - diamino-diphenyl, m.m1 - diamino - para - xylene, m.m1 - diamino - p.p1 - diethyl benzene, b -b 1 - diamino - diethyl - ether and 2 - amino - methyl - 4 - amino furane.  The reaction of the diamine and COS is preferably effected at room temperature in an organic solvent, e.g. an alcohol, benzene, xylene or chloroform.  Oxygen is preferably excluded from the heating of the intermediate product, which may be executed in a solvent such as phenol, cresols or xylenols.  The average chain length of the product may be varied by the addition to the reaction mixture of a primary or secondary amine in amount, for example, of 0.5 per cent or less of the total quantity of diamine. In examples, the polythiocarbamate obtained by precipitation on passing COS into an alcoholic solution of deca-methylene diamine was separated and heated (1) in a nitrogen atmosphere, or (2) in vacuo; in the other examples the polyurea was obtained in a similar manner from (3) N-methyl hexa-methylenediamine, (4) a mixture of hexa- and deca-methylenediamines, (5) a mixture of N-methyl hexa- and hexa-methylenediamines, and (6) deca-methylenediamine.  The products may be worked up into threads and filaments, and by moulding, extrusion, casting, injection moulding or calendering into films, foils, tubes, profiled or unprofiled bars or other moulded articles, or they may be applied in coatings, e.g. cable and wire coatings. Specification 524,795 is referred to.

The longitudinally-vibrating cylindrical resonators used in the filter described in the parent Specification, are replaced by resonators of parallelepipedal shape. The resonators may be in the form of blocks 1, Fig. 1, coupled by wires 3 or the whole system, including resonators 12 and couplers 20, 21, Fig. 5, may be stamped out of a metal lamina. The couplers vibrate in a flexural mode. The degree of coupling is determined by the distance of the points of attachment of the couplers from the centres of the resonators, being a maximum when the couplers are attached, as in Fig. 1, to the extremities of the resonators where the vibrational amplitude is greatest. The coupling wires 3 are attached by welding and may consist of several short lengths or may run the whole length of the filter being connected, where necessary, to end supports. In constructions where the couplers, e.g. 13, Fig. 3a, are at one or both extremities of the (laminar) resonators, the edge or edges of the resonators and the couplers may lie in planes at rightangles to the main plane of the filter.
