Title: Apparatus for energizing electrical precipitators and the like
Inventor: WHITE HARRY JAMES
IPC: B03C3/66
Filed: 1951-03-08
Abstract: 691,341. Converting; supply systems for electrostatic precipitators. RESEARCH CORPORATION. March 8, 1951, No. 5633/51. Classes 38 (ii) and 38 (iv). [Also in Group XL (c)] A high D.C. voltage for energizing an electrical precipitator is obtained from a low voltage D.C. source by rectifying the output of an oscillatory circuit fed from the source and the capacitor of which is associated with a thyratron which when fired varies the charge in the capacitor. One circuit described comprises an oscillatory circuit Lal, Ca<SP>1</SP> connected in series with a D.C. supply 11a. The capacitor Ca<SP>1</SP> also forms part of an oscillatory circuit of much higher frequency including an inductor La3 and thyratron Ta so that when the thyratron is fired the capacitor discharges through the circuit and due to the inductor La<SP>3</SP> charges in the reverse sense. The D.C. source and the voltage across the capacitor then causes the main circuit to oscillate. A coil La<SP>2</SP> is loosely coupled to the inductor La<SP>1</SP> to form a step-up transformer the output of which feeds a voltage doubler rectifier and finally the precipitator 15a. The repetition frequency of the pulses fed to the grid of the thyratron to cause the thyratron to fire is preferably equal to the natural frequency of the main oscillatory circuit. In an alternative circuit, Fig. 2 (not shown), the capacitor is connected directly across the inductor La<SP>1</SP> and the D.C. supply is in series with the thyratron. The output may alternatively be obtained from a separate transformer in series with the inductor.

Title: Improvements in or relating to two chamber injection ampoules
Inventor: WIMMER HANS
IPC: B01F13/00
Filed: 1968-02-05
Abstract: 1,214,053. Two-compartment injection ampoules. H. WIMMER. 5 Feb., 1968, No. 5744/ 68. Heading A5R. Two-compartment injecton ampoules comprising an ampoule barrel adapted to receive an injection needle at one end, and having a resilient sealing piston at the other end and an intermediate piston which initially divides the ampoule into two compartments, the contents of which are mixed by moving the intermediate piston towards the sealing piston, and the ampoule contents are injected by urging both intermediate and sealing pistons down the ampoule, are characterised in having a plunger which moves the intermediate piston so that, on movement of the intermediate piston towards the sealing piston, a previously sealed channel is opened which connects the two compartments across the intermediate piston and, during injection, both pistons are movably connected and move together down the ampoule. In the embodiments illustrated in Figs. 1-10 (Figs. 2-10 not shown) the bore of the piston 103 and the plunger 106 fitting into it are so shaped that in the initial position they together constitute a seal between compartments 109 and 110 but movement of the plunger to urge the intermediate piston towards the sealing piston causes relative movement therebetween and a channel is opened between the thinner end portion 161 of the plunger and the piston, the abutment ridge 115 (which is channeled to allow passage of liquid) urging the piston in the correct direction. When the two pistons meet and mixing is complete, the sealing piston (and hence the intermediate piston also) are urged down the ampoule by means such as a shaped ridge 197 on the plunger cooperating with a groove of appropriate profile in the sealing piston (Figs. 1 to 5). Alternatively, an additional plunger fitted outside the plunger for the intermediate piston and acting on both the sealing piston and the inner plunger (Figs. 8, 9, 10 and 12) may be used. Figs. 12 and 13 (not shown) depict a device in which a duct 12a passes axially through the plunger 6a from a point 19 initially closed by the piston 3a but which opens into the upper compartment when the plunger first moves, the ridge 20 serving to hold the plunger and piston together with the duct open during subsequent movement of the plunger.

Title: Adders and multipliers

Filed: 1975-02-11
Abstract: 1496935 Adder; multiplier TRW Inc 11 Feb 1975 [11 Feb 1974] 5800/75 Heading G4A A binary full adder includes three pairs of input terminals receiving complementary binary signals representing input and carry bits and a plurality of non-threshold logic circuits connected to the inputs to form eight AND gates, and to the outputs of the AND gates to form four OR gates whose outputs provide complementary binary signals representing sum and. carry bits. The adder is used in a matrix, arrangement forming a multiplier suitable for construction as an integrated circuit chip. The term "non-threshold" means a circuit whose output changes between binary levels with a linear relationship to the changing input responsible for the output level change. Such circuits result in faster operation particularly where a number of cascaded stages are involved as in the multiplier. Adder.-The adder includes a number of four-emitter PNP transistors 10, 12, 14 &c. (each shown as four single emitter transistors) coupled to the input bit lines Si, Si, Ri, Ri, Ci, Ci, and to eight bus lines 22-36 each of which forms the output of a respective AND gate. Each bus is coupled to a double-emitter NPN transistor 38-52 whose emitters are coupled to four output lines Co, Co, So, So as shown, each line being the output of an OR gate. The output lines represent in true and complement form the sum and carry outputs. M.O.S. transistors may be used. Multiplier.-The multiplier consists of a matrix array of logic circuits formed at the intersections of orthogonal sets of bit lines carrying the multiplier and multiplicand. The arrangement described operates with fractional 2's complement representation. Each logic circuit, except for some around the periphery of the array, includes a logic circuit forming the product Xi . Yj of multiplier and multiplicand bits applied to row and column inputs and a full adder, as above, with six inputs receiving complementary signals representing the product Xi. Yj and sum and carry inputs form respective ones of two other matrix positions. The Specification gives the logic and full circuit diagram for each matrix position including peripheral positions. The output of the multiplier may be. truncated with rounding of the least significant bit.
