Title: System for controlling a strobe lamp
IPC: H05B41/34
Filed: 1975-10-31
Abstract: 1485674 Supply circuits for strobe lamps; voltage multiplying rectifiers GRIMES MFG CO 31 Oct 1975 [26 Dec 1974] 45532/75 Headings H2H and H2F A circuit for successively firing and completely extinguishing a strobe lamp 10 comprises a capacitor bank 55-60, an A.C. source 35 for charging the capacitor bank and a switching circuit 25, the switching circuit being conductive prior to each firing of the lamp to charge the capacitor bank and being non- conductive at the firing instant and for a predetermined period thereafter to allow complete extinguishment of the lamp. Each set of capacitors 55-57 and 58-60 is part of a voltage doubling circuit and the two sets are connected in series to supply to the lamp a voltage equal to four times the peak voltage of the source 35. The capacitors are charged via a diode 81 and a thyristor 80. After a predetermined number of A.C. cycles, a counter 45 supplies a pulse on line 31 to the circuit 25 and causes a circuit 50 to supply a firing pulse via a transformer 40 to flash the lamp. The pulse on the line 31 switches on a transistor 85 which in turn switches off the thyristor 80 thereby preventing the charging of the capacitor bank 55- 60 for the duration of the pulse. The lamp deionizes and at the termination of the pulse on the line 31 a zero crossing detector 30 allows the thyristor 80 to be switched on again at the next zero crossing of the A.C. supply. In a modification, Fig. 3 (not shown), the thyristor 80 is switched off when the capacitor voltage reaches a selected one of two voltages to enable lamps of two different energy requirements to be operated.

Abstract: 1348568 Piston inserting SEAL POWER CORP 1 Oct 1971 [12 Nov 1970] 45726/71 Heading F2T  A sleeve 20 for inserting a piston into a cylinder comprises a body 22 having a tapered bore 30 and a lip at the exit end 26 for piloting the sleeve a short distance into the combustion chamber end of the cylinder. The sleeve may be made of acrylonitrile-butadiene-styrene or of polyurethane with a stainless steel liner (72), Figs. 9 and 10 (not shown). In use, the piston is first inserted into the sleeve from the entrance end 24, piston-rod first, to compress the piston rings. The piston is then lowered into the cylinder until the lip of the sleeve comes to rest within a chamfer at the end of the cylinder bore. The sleeve is then held while the piston is forced completely out and into the cylinder. To facilitate manual gripping of the sleeve, the outer surface may be ridged.

Title: Improvements in carbonyl-containing organosilicon materials and a method for making them
IPC: C08G77/00
Filed: 1965-11-02
Abstract: The invention comprises carbonyl-containing silanes and siloxanes of formula (I) <FORM:1092156/C3/1> and copolymers and homopolymers derived therefrom.  The homopolymers consist essentially of units of the formula (II) <FORM:1092156/C3/2> and the copolymers consist of 0.01 to 99.99 mole per cent of units of Formula (II) combined with 99.99 to 0.01 mole per cent of units of formula <FORM:1092156/C3/3> In the above formulae R is a monovalent halogenated or unhalogenated hydrocarbon radical or a cyanoalkyl radical, R1 is a divalent halogenated or unhalogenated hydrocarbon radical, A is hydrogen, an R radical, a halogen atom or an alkoxy radical, Z is an arylene radical, a divalent aryl ether radical of the type -Ar-O-Q-where Ar is an arylene radical and Q is a hydrocarbon radical, a divalent five-membered heterocyclic aromatic radical having a Group VIa element as the hetero atom, or a substituted derivative thereof, Y is <FORM:1092156/C3/4> or an alkylene radical, a is 0 or 1, b is 2 or 3, c is 0, 1 or 2 and d is 1, 2 or 3.  The compounds of Formula (I) are prepared by acylating an aryl nucleus, including the above defined heterocycles, with a silyl acid halide of formula <FORM:1092156/C3/5> where X is a halogen atom.  If these monoacylated compounds contain a methylene group alpha to the aryl nucleus, they may be converted to the diacylated compounds by oxidation of the methylene group. Alternatively the diacylated compound may be prepared by reducing the carbonyl group of a monoacylated compound to a methylene group with a metal hydride e.g. LiACH4 in the presence of aluminium diboride, acylating the product to produce a carbonyl group attached to the aryl nucleus and then oxidizing the methylene group back to a carbonyl group. Polymers and copolymers may be prepared by hydrolysing these compounds or cohydrolysing them with an organo halo silane. Examples describe the preparation of p(trimethysilylethyl) trimethylsilylbutyrylbenzene, a homopolymer of the formula <FORM:1092156/C3/6> a copolymer comprising about 5 mole per cent of units derived from this combined with about 95 mole per cent of dimethylsiloxy units, and a vulcanizing composition prepared by mixing the homopolymer of Example 2, ethyl polysilicate and dibutyl tin dilaurate.

Abstract: 1,140,829. Fuel cell gas manifold system. UNITED AIRCRAFT CORP. 13 Oct., 1967 [7 Nov., 1966], No. 46711/67. Heading H1B. In a fuel cell containing an aqueous electrolyte disposed between a fuel electrode and an oxident electrode, in which a fuel gas is supplied to the fuel electrode and oxidant gas to the oxidant electrode, at least one of the gases is distributed over the surface of its electrode by passage through a chamber in which the inlet and exit ports are closely adjacent to each other and to the electrode surface. In Fig. 1 gas enters chamber 24 by inlet port 26 and flows over the electrode surface round the baffle 25, as shown by arrow 27, to leave at outlet port 28. Any excessive drying near port 26 can thus easily be made good by diffusion of electrolyte from the comparatively " wet " region near port 28. Suitable gases are hydrogen and dry air; suitable electrodes contain Pt or Pd catalyst with PTFE binder on a nickel mesh; the electrolyte may be 30% aqueous KOH (or NaOH, LiOH, RbOH or CsOH); the electrolyte matrix may be of asbestos and be 0À1-0À2 inch thick.

Abstract: 1495198 Toy figure PLAYMATES INDUSTRIAL CO Ltd 28 May 1976 [12 Nov 1975] 46745/75 Heading A6S In a toy figure, pivotal movement of arms 1, 2 is transmitted via a longitudinally extending shaft 12 to legs 3, 4 to simulate a co-ordinated walking movement of the limbs. As shown, pivotally mounted arms 1, 2 are connected via cylindrical portions 27, 28 and fork elements 29, 30 to an upper transverse end part 19 of the shaft whereby pivotal movement of either arm is effective in rotating the shaft and which thereby via a lower transverse end part 22 which abuts projections 37, 38 on the legs 3, 4 imparts a walking motion to the legs. In an alternative arrangement (not shown) the transverse upper end part of the shaft terminates at each branch end in knob formations which are retained in the respective bifurcations of the fork elements carried by the arms, and the lower transverse end part terminates each branch end in a bifurcation which retains a knob formation at the respective co-operating extremities of the leg projections-the latter refinement ensuring that any leg motion is transmitted to the arms. All parts may be formed of plastics material; the shaft may as an alternative be formed of metal.
