Title: Improvements in or relating to pulse generators
Inventor: MARTIN EDWARD ALBERT
IPC: H03K3/315
Filed: 1969-03-10
Abstract: 1292054 Pulse generator SOLARTRON ELECTRONIC GROUP Ltd 9 March 1970 [10 March 1969] 12518/69 Heading H3T A pulse generator has a tunnel diode 41 coupled to feedback means including first and second non-inductive delay circuits 18<SP>1</SP>, 19<SP>1</SP> ,  17<SP>1</SP> and 57, 58, 221, the feedback means is such that in operation the diode can automatically switch from its low voltage to its high voltage state and vice-versa, the feedback by the first delay circuit 18<SP>1</SP>, 19<SP>1</SP>, 17<SP>1</SP> is insufficient to effect such switching, and the time constant of the first delay circuit 18<SP>1</SP>, 19<SP>1</SP>, 171 is shorter than that of the second delay circuit 57, 58, 22<SP>1</SP>. When the tunnel diode 41 is in its low voltage state at current level (28, Fig. 2, not shown) the output from transistor 51 is high so that the feedback via the delay circuit 18<SP>1</SP>, 19<SP>1</SP>, 171 increases the current through the diode to a current level (27) insufficient to change the state of the diode. Then feedback via the longer time constant delay circuit 57, 58, 22<SP>1</SP> further increases the current through the diode above the level (29) to cause the diode to switch to its high voltage state The output from transistor 51 changes to a low level and the delay circuits act as integrating circuits. Delay circuit 18<SP>1</SP>, 19<SP>1</SP>, 17<SP>1</SP> causes the current through the diode to decrease to a level (28) and delay circuit 57, 58, 22<SP>1</SP> further decreases the current through the diode to a level (30) where it changes back to the low voltage state. The above is repeated to generate an output at 13<SP>1</SP>. The larger time constant circuit includes resistors 18<SP>1</SP>, 57, 58, 21<SP>1</SP>, 60, capacitor 221 and a transistor 59. The pulse generator may be made to' operate at a higher frequency than its natural frequency by triggering it with higher frequency trigger pulses at 14<SP>1</SP> capable of causing current through the diode to swing above the level (29) and below the level (30) such that the pulse generator acts as a pulse frequency divider synchronized to the trigger pulses. If the trigger pulses are not capable of this then the generator is synchronized to the input trigger pulses. With switch 45 closed to short capacitor 42, switch 46 is open to render the longer time constant circuit 57, 58, 22<SP>1</SP> inoperative so that the tunnel diode is then triggered to its two stable states by input trigger pulses applied at 14<SP>1</SP>. Alternatively switch 46 may be replaced by a switch connected across capacitor 22<SP>1</SP>. The pulse generator may be used as a triggering circuit for an oscilloscope to synchronize the time base with the waveform to be displayed so that the time base locks on a sub harmonic of the waveform frequency. A variable attenuator or limiter or preamplifier can be included to the input of the generator.

Filed: 1945-05-19
Abstract: 610,030. Hydraulic presses. FITZPATRICK, H. J. (Clearing Machine Corporation). May 19, 1945, No. 12673. [Class 69 (ii)] In' a hydraulic circuit for operating piston and cylinder mechanisms 18, 27, 54, 45 and 68, a main pump 11 supplies liquid through an unloading valve 89, main supply line 14, and control valve 17, 22, 51, 42 and 36, to said mechanisms. The control valves 17, 51, 42 and 36 are actuated by liquid supplied by a pilot pump 59 into the pilot line 61, and through manually-controlled valves 79, 75, 70 and 63 respectively. These valves are provided with electrical means whereby when a valve is moved so that a control valve is actuated to distribute liquid to a mechanism, the valve 89 causes all of the liquid from pump 11 to be delivered to the main supply line, but after a predetermined period the valve is made to byepass the delivery to exhaust pipe 90. The pilot pump 59 supplies liquid through a valve 92 to maintain pressure in the main line 14, this being controlled by a pressure-regulating and relief valve 88. Discharge from the bottom of the cylinders 26 is first through main pipe 30 and then through a restricted valvecontrolled outlet 33 so that the piston 27 is provided with a liquid cushion. An auxiliary pump 104 operates to supplement the flow from the main pump 11 when required, but is normally byepassed through the valve 107 to exhaust pipe 106.

Abstract: 558,131. Centrifugal moulding-machines. KELM, G. R. Oct. 1, 1941, No. 12695. [Class 87 (ii)] Concerns moulding machines of the type wherein the moulds rotate about two intersecting axes, whereby a substance contained within the moulds, e.g. latex, is spread over the interior thereof. The two moulds 21 are rotated as a whole on a shaft 10 and are rotated also about the axis of their stems 21a. The holder for the moulds comprises a block 14 divided into two sections which are clamped together and to the shaft 10 by bolts 15. In the block sections there are recessed bores 16 which form bearing surfaces for the heads 17a  of mould-holders 17 each having a bore 19 into which the stem 21a fits with a bayonet-slot connection, the stem bedding on a spring x. Each mould-holder has arms 17c one of which, on each rotation of the shaft 10, strikes a projection 25 on a collar 26 adjustably clamped to a stationary sleeve surrounding the shaft 10, and rotates its mould-holder through 90 degrees. During the intervals between engagements of the arms 17c with the projection 25, the mould-holder is held stationary by frictional engagement between a flange 26a on the collar 26 and a square part 17d of the mould-holder; during the rotation through 90 degrees, the leading corner of the square is received in a recess 26b in the collar 26, as shown in Fig. 3.

Title: Process for the preparation of zinc and lead compounds
IPC: C01G9/00
Filed: 1956-04-26
Abstract: Zinc or lead basic carbonates or carbonates are prepared by mixing zinc oxide or lead monoxide with aqueous ammonium carbonate at atmospheric pressure to form a mouldable paste, moulding the paste, solidifying and drying.  The moulded product may be heated to decompose the carbonate to oxide, and the latter ground if necessary. The mixing operation is preferably effected in an atmosphere of carbon dioxide, and if desired the initial oxide may be formed into a paste with aqueous ammonia and carbon dioxide injected therein.  The moulded products are particularly useful for desulphurizing gases. According to examples, (1) zinc oxide was mixed with a saturated ammonium bicarbonate solution containing solid bicarbonate to form a paste which was moulded, allowed to solidify, and dried.  A product containing 92% zinc carbonate and the remainder, hydroxide resulted. The product was capable of absorbing hydrogen sulphide at 300-400 DEG C.  The spent, sulphur saturated mass may be ground and calcined, and the resulting product zinc oxide, treated in a manner similar to (1) above to form a product containing 62% zinc carbonate, 5% hydroxide and the balance, zinc oxide.  This was also suitable for absorbing hydrogen sulphide.  (4) Lead monoxide was mixed with a slurry of ammonium bicarbonate at 15 DEG  C. and the resultant paste was moulded, solidified and dried.  The product contained 12% of hydroxide.
