Filed: 1949-06-09
Abstract: 660,939. Electric selective signalling. DEHN, S. G. (Collins Radio Co.). June 9, 1949. No. 15404/49. Class 40 (i) Apparatus for positioning a, shaft in any one of a fixed number of angular settings comprises n ganged, rotary, changeover switches at the transmitter connected by n lines to a similar bank of n changeover switches at the receiver, each switch being operated by an individual cam, so that for each angular setting at the transmitter an earth is placed on one or more of the n lines which is passed on by one or more of the receiver switches to a relay circuit, to energise a motor and rotate the ganged receiver switch shaft, and the relay energising circuit is only broken when the receiver shaft setting is consistent with the angular setting at the transmitter, causing the motor to stop. As shown (Figs. 1 & 2) for n = 4, a ten position bank of switches 13-16 produces ten different sets of conditions on the lines 17-20, so that except when the receiving switches 13a-16a have the same angular setting as the transmitting switches, an earth is placed on the line 34a to energise relay winding 39, closing its contacts 41/42, and energising motor 43 to rotate shaft 5a to which is assembled the receiver switch bank and also rotating the receiver shaft 4, until the switch settings are consistent, when the earth is removed from relay 39 and the motor 43 stops. The switches may alternatively be of the "wafer-biscuit" type (Fig. 4). A spring-loaded pawl may be attached to the armature of the relay engaging a toothed wheel on the controlled shaft to hold the shaft on de-energisation of the relay winding, the motor being coupled to the shaft through a friction clutch.

Title: Process and apparatus for the production of synthesis gas comprising hydrogen and carbon monoxide
IPC: C01B3/38
Filed: 1953-02-26
Abstract: <PICT:0777325/III/1> In the production of synthesis gas by the reaction of hydrocarbons and a gas containing oxygen in a reaction chamber containing a catalyst bed at a high temperature, undesired reactions are prevented and the desired reaction is controlled by feeding the reactants to the catalyst bed at a rate of flow above that at which he undesired reactions take place and optionally above the speed of ignition, cooling the reactants prior to their introduction into the reaction chamber, the cooling being to a temperature below that of ignition when the rate of flow is below the speed of ignition, and providing the reaction chamber with an internal coating of catalytically active material at those parts contacted by the reactants.  As shown air introduced through inlet 1 is mixed first with oxygen from inlet 2 and then with a hydrocarbon gas from inlet 6.  The resulting mixture is cooled by passing in spiral flow around a centre tube 10 which is surrounded by a coil 12, cooling water being passed through the central tube and surrounding coil via inlet 7 and outlet 13.  The cooled mixture passes into a reaction chamber 18 which is lined with active catalyst material 14 and contains a catalyst bed 17. Movement of the mixing and cooling assembly with respect to the reaction chamber is made possible by stuffing box 15 and flexible connexions 16.  The bed of catalyst may be arranged so that the size of the individual grains or the like of the catalyst decreases from the inlet to the outlet of the bed. Alternatively or in addition, when the catalyst consists of a catalyst and a carrier therefor, the concentration of the catalyst on the carrier may be increased from the inlet to the outlet.  Inert refractory material may be placed at the inlet.

Abstract: 1,210,981. Semi-conductor devices. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. 5 Feb., 1968 [7 Feb., 1967], No. 5652/68. Heading H1K. In a method of producing integrated complementary silicon transistors T 1 , T 2 , an N-type epitaxial layer is formed on a P-type substrate and divided into islands by the diffusion of P-type impurity to form isolating wall regions 6. The emitter 7 of transistor T 2  is diffused simultaneously in one island. This is followed by the diffusion of P-type material to form the base 8 of transistor T 1  in a further island and also the annular collector 9 of transistor T 2 , and the diffusion of N-type material to obtain the emitter 10 of transistor T 1  and the collector and base contacts 11, 12 respectively of the two transistors. The isolating walls 6 are formed by providing doping material deposits opposite one another on either side of the epitaxial layer at positions where walls are required, those buried below the layer having been provided before the deposition of the layer itself, and diffusing in a neutral atmosphere. In this same process a further doping material deposit on the free surface of the epitaxial layer is diffused to form region 7. Diffusion of the other regions follows by conventional means. Boron is used as the P-type and phosphorus as the N-type impurity, regions 6, 7, 10, 11 and 12 being strongly doped compared with the other regions. Aluminium is vapour deposited to form contacts.
