Abstract: 1,045,108. Transistors. INTERNATIONAL BUSINESS MACHINES CORPORATION. Aug. 24, 1965 [Sept. 23, 1964], No. 36418/65. Heading H1K. A transistor is formed by a process comprising epitaxially growing a semi-conductor body having two regions of different basic material, said materials having different band gaps, and heating the body to cause diffusion from one region to the other so as to change the other region to the opposite conductivity type. In an embodiment, a layer of Ge is grown epitaxially on a substrate of GaAs to give a PP heterojunction. The device is then heated under arsenic pressure in a closed tube to 500 to 700 C., thus causing some As to diffuse out of the GaAs and into the germanium giving a device as shown in Fig. 2B. The device formed is a wide-gap emitter, drift field base transistor. In another embodiment a GaP substrate has a Si layer grown thereon and some of the phosphorus is subsequently diffused into the silicon.

Title: Improvements in receiver relays for electric remote-control installations
IPC: H02J13/00
Filed: 1955-12-21
Abstract: 805,355. Actuation of switches. COMPAGNIE POUR LA FABRICATION DES COMPTEURS ET MATERIEL D'USINES A. GAZ. Dec. 21, 1955 [Jan. 6, 1955; June 30, 1955], No. 36648/55. Class 38 (5). A receiver relay for remote-control operates in a manner dependent upon the interval between two audio-frequency pulses super - imposed on a power distribution circuit and has an electromagnetically released yoke 20 which closes a switch 29, 29<SP>1</SP> to energize a synchronous motor 1 and moves switch atcuating levers 36, 44 into the paths of indexes 35, 43 driven by the motor. The first pulse energizes the coil 15 through a tuned frequency selector circuit 10, 11, 12, 13a, 13b so that a spring armature 16 is attracted to release the yoke 20 which is biased for rotation about a fixed spindle 21 by a spring 22. A pin 23 on the yoke 20 engages a spring contact carrier 27 to close the contacts 29, 29<SP>1</SP>. As the motor starts to rotate a cam 31 on the driven shaft 3 acts on a follower 26 on a lever 24 so as to force an insulating part 8 against the spring 27 and maintain the contacts 29, 291 closed until the shaft 3 has completed one revolution. The shaft 3 also carries a cam 30 which acts on a pin 4 on a lever 5 against the action of a spring 7 so that the lever 5 resets the yoke 20 in a hole 18 in the armature 16 each time after it has been released by a pulse. The second pulse is timed to occur just before one of the indexes approaches a lever 36 or 44 and the yoke 20 moves the levers against biasing springs (not shown) into the paths of the indexes. If this pulse is arranged to occur just before the index 35 reaches the lever 36 this lever is rotated about the spindle 21 to open contacts 39, 39<SP>1</SP> and is latched by a spring 41. If the second pulse occurs just before the index 43 reaches the lever 44 this lever is rotated to deflect the latching spring 41 and allow the lever 36 to return and contacts 39, 39<SP>1</SP> to close. Arrangements are described (Figs. 4 to 7, not shown), with two switches each operable by two spaced indexes for closing and one for opening or vice versa. It is thus possible to arrange for three switch positions (e.g. one open, the other open, both open) depending on the time interval between the last two pulses received. Only one index mounting disc 32 per switch may be provided, the lower index being bent downward to operate the lever 44.

Title: Method and Apparatus for Sampling Waste Gas
IPC: G01N1/22
Filed: 1966-08-16
Abstract: 1,155,142. Filtering sample gases in steel making. BETEILIGUNGS-UND PATENTVERWALTUNGS G.m.b.H. 16 Aug., 1966 [17 Aug., 1965], No'. 36651/66. Heading B1T. Sample gas, from the effluent of a basic- ; oxygen steel making plant, is drawn through a probe 1, a filter 3, a condenser 5, a pump 6 and delivered to parallel gas analysers 7, and a flowmeter 9 and pressure gauge 13 monitor the conditions in the circuit and serve firstly to clean the filter and condenser by application of pressure gas if recorded values vary excessively and otherwise to maintain flow rates through analysers 7 constant. Flowmeter 9 controls a bleed valve 9, in parallel with analysers 7, directly to maintain constant flow, but if the flow falls to a point where valve 8 completely closes this causes filter cleaning. While filter 3 is being cleaned, valve 14 may switch over to a parallel filter and probe circuit to maintain the flow to the analysers. Pressure gauge 13 may control the filter cleaning directly, and the total flow may be varied by varying the pump delivery. Filter 3 is a flat, circular, glass fibre filter and is cleaned by a combination of reverse flow gas from valve 4 and upstream flushing gas from valve 4a, both discharging out of probe 1. Some gas from valve 4 passes through condensor 5-and valve 16. The various valves are solenoid-operated and valves 2, 4, 16 may be operated to discharge dust from filter 3 and water from condenser 5 in sequence. Valve 2 and filter 3 may be heated above 100‹C to inhibit condensation. The cleaning step may be initiated automatically by the withdrawal of the blowing lance at a break in the steel making process. During such a break, valve 2 may be closed, with pump 6 running, and flowmeter 9 and pressure gauge 13 used to check for leaks in the pipework. An increasing pressure recorded by gauge 13 under operation indicates a leak or pump failure, and after switching over to the other filter, to assess which fault has occurred, a signal is transmitted by control device 11 to desk 18. Likewise any failure in the cleaning of a filter, as indicated by 9 or 13, is transmitted to desk 18. The cleaning, switch over and leak tests may all be controlled from desk 18.

Filed: 1970-07-29
Abstract: 1284017 Zone melting COMMISSARIAT A L'ENERGIE ATOMIQUE 29 July 1970 36724/70 Heading B1S [Also in Division F4] Apparatus for growing crystals comprises a water cooled furnace body 10 provided with a base 12, a domed cover 14, resistance heating elements 36 and a melt containing crucible 16. In operation, a crystal is pulled from melt 34 under vacuum, or in a nitrogen, argon or, helium or reducing atmosphere introduced via inlet 44 and plenum chamber 40, whilst the crucible 16 and the crystal pulling rod 20 are rotated by their respective motors 50, 50'. The crystal is pulled by rod 20 being raised, the crucible 16 likewise being raised at a relative rate determined by the desired crystal growth rate. This desired raising is effected by corresponding raising of the crucible and rod supports 52, 52' along hollow columns 54, 54' to which the supports are splined, in response to the drives from motors 56, 56', 58 and 58' transmitted through screw and nut gearing (Fig. 4 not shown) mounted within the columns. Once a desired crystal length has been pulled and detached from melt 34 and subsequently cooled, jack 80 raises shaft 72, and with it lateral arms 70, 88 which carry the cover 14 and the crystal pulling rod 20 with its drive and support means, respectively, so that cover 14 and rod 20 together with the crystal grown on it are moved clear of furnace body 10. In this raised position (Fig. 2 not shown), keys 76 on shaft 72, which previously prevented the shaft 72 rotating, by running in keyways 78 in bearing members 74 used to guide and mount the shaft, are raised clear of the keyways 78, to allow rotation of the shaft 72 and so pivoting of the arms 70, 88 and the cover 14 and crystal puffing rod 20 clear of the furnace body 10, whereby the crystal may be removed from the rod. Slots 77 in a U sectioned supporting frame 28 which carries the bearing members 74, limit the degree of pivoting of the arms 70, 88 to an amount just sufficient for the rod 20 to swing clear of furnace body 10. Clear access to furnace body 10 or crucible 16 may be obtained after withdrawal of rod 20 from cover 14 by swinging the latter about pivot pin 68 clear of the furnace body (Fig. 3 not shown) after release of latch 71.

Filed: 1954-12-22
Abstract: 755,098. Printing-machines. GRIMM, E., and GRIMM, K., [trading as GRIMM, E. METALL-PRAZISIONSWERKSTATTE]. Dec. 22, 1954 [Jan. 8, 1954], No. 37044/54. Class 100 (2). Cleaning devices for damping and like rollers.- Absorbent damping rollers, e.g. for use in lithographic printing machines are cleaned by being rotated in contact with a cleaning liquid which is then squeezed out by being rolled against another roller under pressure. As shown in Fig. 1, the roller 12 to be cleaned is supported on a pair of rollers 2, 3 which are driven from a motor 4 and dip in the cleaning liquid 11. This causes the roller 12 to become saturated with the liquid and to loosen all adhering ink, dust, &c. The roller is then transferred to the position 12a supported on rollers 13, 14 and a further roller 19 is arranged to bear downwardly on it. The roller 19 is carried on arms 20 on a spindle 22 connected to a handle 23 whereby the roller may be lifted into an unoperative position. An adjustable over-centre spring 25 applies the downward pressure of the roller. The liquid is expressed by the rolling contact of the rollers 13, 14 and 19. Helical grooves may be cut in the surfaces of rollers 14 and 19 to conduct the liquid expressed away from the rollers. These grooves may run outwardly from the centre of each roller or in opposite directions on the two rollers. The roller 13 may have a smooth cylindrical surface. The rollers 13, 14 and 19 may be formed by a tubular central member coated with rubber. Instead of the helical grooves the cylinders may be formed with perforations, as at 40 in roller 13, which allow the expressed liquid to pass into the interior. Instead of being supported on two rollers 13, 14, the roller 12a to be cleaned may be supported on a single driven roller 28, Fig. 4, movement away from this roller being prevented by a prop 32 having a roller 31 bearing on the spindle ends. Pressure may again be applied by a roller 19 as shown in Fig. 1 or, as shown in Fig. 4, the pressure may be applied by rollers 35 which act, in the same way as rollers 31, on the spindle ends of the roller to be dried. Pressure is applied to rollers 35 by means similar to those described for roller 19 in Fig. 1.
