Patent GB-959293-A (GB)
Title: Improvements in or relating to piezoelectric devices
IPC: H03H9/30
Filed: 1961-01-16
Abstract: Zinc oxide crystals are grown from a vapour phase by causing zinc vapour and oxygen to combine in a furnace at 1250-1300 DEG  C. The furnace comprises concentric inner and outer tubes of aluminium oxide, the smaller tube being open-ended.  Zinc powder is placed near the end of the smaller tube and air is blown through until equilibrium is reached at the above temperature, after which a carrier gas mixture of nitrogen and a minor amount of wet hydrogen is passed over the zinc oxide powder. Reduced zinc vapour is carried out of the inner tube into the central region of the furnace where it reacts with the oxygen of the air to produce crystalline zinc oxide growth in the vicinity of the end of the inner concentric chamber. The crystalline mass is withdrawn with the inner tube.  Specification 959,294 is referred to.

Title: Improvements in or relating to electronic calculating apparatus
IPC: H03K23/82
Filed: 1945-01-27
Abstract: 600,508. Pulse counting circuits. NATIONAL CASH REGISTER CO. Jan. 27, 1945, No. 2189. Convention date, Jan. 27, 1944. [Class 40 (vi)] [Also in Group XIX] In a counting ring, a number of trigger-connected' pairs of valves are arranged with connections between the valves such that one pair only responds to a pulse applied to all the valves, priming another pair to respond to the next pulse. Valves 0-4 and 5-9 are arranged in pairs, the anode of valve 0 being connected over resistance 118 and condenser 119 to the grid of valve 5, while the anode of valve 5 is connected over resistance 107 and condenser 108 to the grid of valve 0, the grid of each valve being connected over resistance 94 to a large negative potential. The grid of valve 0 is also connected over resistance 134 to the anode of valve 4, the grid of valve 5 being connected over a resistance to the anode of valve 9. By opening the switches 88 temporarily in the screen grid leads of valves 5-9, the valves 0-4 are rendered conducting (shown by shading) prior to the receipt of a train of pulses. A negative pulse applied over terminal 105 is fed over coupling condensers to the grids of all the valves, being ineffective on the non- conducting valves 5-9. The grids of the conducting valve 1-4 are connected over resistances to the anodes of non-conducting - valves but the grid of valve 0 is connected over resistance 134 to the anode of valve,4 with the result that the grid of valve 0 is less positive than the grids of valves 1-4. The negative pulse is therefore effective in reversing the state of the pair of valves 0, 5 in preference to any other pair. The grid of valve 5, due to the connection to the anode of valve 9 has less negative potential than the valves 6-9, thereby aiding the triggering operation. By employing a switch with two arms for sensing the potential of corresponding electrodes of different valves, the state of the ring may be determined and an indicating device operated. Specification 600,503 is referred to.

Abstract: 1,082,211. Reflux heads for fractionating columns. Q.V.F. Ltd., and K. T. POOLE. Dec. 17, 1964 [Jan. 17, 1964], No. 2228/64. Heading B1B. In a reflux head for a fractionating column wherein the vapour rises from chamber 1 through aperture 4 into vapour/liquid separator 2 and then flows to the condenser, chamber 1 is provided with movable funnel 7 which in one position conveys the refluxed condensate from conduit 5 back into chamber 1 and in another position conveys the condensate into conduit 6 so bypassing chamber 1, the driving mechanism for the funnel being arranged in outwardly extending tubular elements 21 through which the funnel may be withdrawn for repairs and replacemet. The funnel is carried by an arm 15 which has its ends in slipping blocks 14 and 17. On energising a solenoid 20 a rod 18 carrying the block 17 moves inwardly pushing the arm and so displaces the funnel to the by-pass direction. A spring 10 on a pin 11 which carries the block 14 consequently returns the arm and funnel to the original position. To remove the funnel the end plate 13 of the tubular element carrying the pin and spring is uncoupled from its associated collar 23 and the arm 15 and funnel may be withdrawn as the arm is a loose fit in block 17. Bellows 29 sealed to the slipping blocks and to the gaskets 25 provided between the end plates 13 and the tubular element 21 are provided to allow for movement of the blocks but to segregate the vapour chamber from the bores in the end plates. Another form of reflux head is described in which there is only one tubular element for withdrawing the funnel.

Abstract: 795,895. Vapour vacuum pumps. EDWARDS HIGH VACUUM, Ltd. Jan. 22, 1957 [Jan. 25, 1956], No. 2531/56. Class 71. A vapour vacuum pump comprises a baffle and one or more thermojunctions in thermal conducting relationship with the baffle and having means for passing an electric current through said thermojunctions. In the embodiment shown in Fig. 1, the baffle consists of a thick copper ring 6 supporting a number of annular copper rings 7 and one plain copper ring 8 by means of copper struts 9. The assembly is polished to reduce radiation heat gain and is supported between two separate rings of copper pipe 2 and 3 by a number of strips of thermofunetion material 10, 11, 12 each having the cold junction in good thermal contact with the ring 6. Cooling water is supplied to the pipes 2 and 3 and on passing an electric current in the appropriate directions through the strips 10, 11 and 12 the baffle assembly is cooled below the temperature of the cooling water. If the current is reversed the temperature of the baffle becomes above that of the water which prevents condensation when opening the apparatus to atmosphere. One or both of the pipes 2 and 3 may be replaced by a copper ring which may form part of the wall of the pot 1, being insulated from it, and these rings may be cooled by external cooling fins. The pot 1 is mounted between the portion of the pump to be connected to the system to be exhausted and a pump isolating valve.

Abstract: 508,594. Recovering carbon black and hydrocyanic acid from gases containing acetylene. JOHNSON, G. W. (I. G. Farbenindustrie Akt.-Ges.). Jan. 27, 1938, No. 2652. [Classes 1 (ii) and 90] [Also in Group IV] Carbon black, and hydrocyanic acid if present, is separated from gases containing acetylene obtained by the thermal splitting of hydrocarbons by quenching the gases with water, preferably by spraying in water to give a gas-vapour mixture with a temperature of 50-80‹ C., and then washing the moist gases with water at an elevated temperature, e.g. 50-80‹ C. The temperature of washing is chosen to minimize the amount of other gases, particularly acetylene, dissolved. According to examples : (1) gases containing acetylene and obtained by treating waste gases from pressure hydrogenation in the electric arc are quenched by spraying in water to give a temperature of 80‹ C. and then washed with water at 80‹ C. The water is led to a settling vessel, and carbon black readily collects on the surface of the water. A second washing tower, using cold water, is connected in series with the first tower. (2) A similar gas is treated to remove carbon black and hydrocyanic acid by quenching to 55‹ C. and washing with water at 50‹ C. The carbon black is removed by settling and the hydrocyanic acid is expelled by passing into a column under reduced pressure and blowing in steam.
