Title: Improvements in or relating to transistors
IPC: H01L27/07
Filed: 1960-12-06
Abstract: 936,812. Transistors. SIEMENS & HALSKE A.G. Dec. 6, 1960 [Dec. 7, 1959], No. 41959/60. Class 37. In a junction transistor comprising an additional electrode which forms a rectifying junction with the base zone at a distance from the emitter junction greater than the emittercollector spacing the electrode is connected directly with the collector electrode. The rectifying junction, poled in the same sense as the collector junction prevents the transistor from being driven into saturation. In an example, Fig. 2, the N-type. base zone is a disc mounted on an annular base contact M, and the additional junction A is formed opposite the contact at the edge of the disc. The device is mounted in a housing through which the emitter, base and collector leads extend.

Title: Exhaust gas recirculation in internal combustion engines
IPC: F02M25/06
Filed: 1974-09-27
Abstract: 1458467 Controlling exhaust gas recirculation in IC engines REGIE NATIONALE DES USINES RENAULT and AUTOMOBILES PEUGEOT 27 Sept 1974 [9 Oct 1973] 42016/74 Heading  FIB [Also in Division F2] An internal combustion engine is provided with a recirculating duct 1, 3 for returning exhaust gases to an induction pipe 4 of a carburetter. The duct 1, 3 incorporates a valve 2 having a head 21, 22 which is spring-biased to close the duct. The valve is opened by applying vacuum (from the induction pipe 4 via conduits 30, 33) to the upper side of a diaphragm 19. The valve head 22 is frustoconical and has a maximum diameter three times greater than its minimum diameter, while its length is less than the maximum displacement of the valve head 7 from the valve seat 10, so that when the valve is completely open, the bore in the valve seat is completely unobstructed. Preferably, a vacuumsensing control orifice 34 in the induction pipe 4 does not lie in a plane normal to the pivot axis 36 of the throttle valve 35, but lies in a plane at 0-45 degrees to the pivot axis 36. Alternatively the vacuum may be sensed from a port 37 located in a Venturi constriction 38. In order to prevent exhaust gas recirculation during idling or when the engine is operating at high load, there may be provided an electromagnetically operated venting valve 45 Fig. 4 for bleeding air above the diaphragm 19 and closing the recirculation valve head 7. The valve 45 is operated by closing either of switches 52, 53. Switch 52 is operated by the choke control and closed at start-up, whilst switch 53 is opened and closed by a cam 58 which rotates via linkage 61 as the throttle 35 rotates. The cam 58 closes the electromagnetic valve 45 via an electric circuit during idling or fully open throttle positions. The control circuit may also include a vacuum reservoir 62 and a check-valve 65/66/67 which maintains a pre-set degree of vacuum in the system, so that when valve 45 is closed, the valve head 7 is open to a minimum pre-set degree, ensuring a minimum amount of exhaust gas recirculation. At idling speed the valve 7 has a tendency to float on the seat 10, which may lead to fouling. To avoid this, the electromagnetic valve 45 may be connected to an air pump (not shown) instead of atmosphere. Alternatively, the recirculation valve can be redesigned to have a sealed chamber below, as well as above, the diaphragm. The lower sealed chamber can be connected to manifold vacuum when the upper chamber is connected to atmosphere, to ensure a strong downward force of the valve head upon the seat.

Abstract: 875,783. Opening and closing moulds for retreading tyres. SUPER MOLD CORPORATION OF CALIFORNIA. Dec. 17, 1959 [Dec. 18, 1958], No. 42956/59. Class 87(2). A tyre is retreaded in a mould comprising upper and lower parts 22, 21, Fig. 6, held together by a locking ring 24 which is in three parts 27, 28, 29, Fig. 10, pivoted together at 30, 31 and held by a catch 32. The mould is opened and closed by placing it in a press having a fixed upper platen 5 and a movable lower platen 6, each platen having a ring 18 operated by a cylinder 14 to engage the tyre beads. In operation, a tyre is vulcanized in the steam or electrically heated mould away from the press, and after vulcanization, the mould supported by trunnions 33 on a dolly 38 is moved to the press. When the mould is moved into the press, after deflation of the curing bag, the legs 41 of the dolly are engaged in notches 44 in the lower platen 6, and are held in the notches by snap action latches 45. The lower platen 6 is then moved upwardly to lift the mould 20 out of the cradles 43, and then by engagement with the arms 42 lift the dolly. The latch 32 of the locking ring 24 is released and the parts spread apart and placed on hangers 86. The construction for supporting the ring when released forms the subject-matter of Specification 875,784. After release of the ring 24, dogs 50 are moved inwardly to engage recesses 52 in the mould parts. The upper and lower rings 18 are then advanced to reduce the diameter of the tyre. The lower platen 6 is moved down to separate the mould parts 21, 22, whilst the upper ring pushes the tyre downwardly out of the upper mould part and the lower ring pushes the tyre upwardly out of the lower mould part. Each ring may be retracted slightly whilst the other ring is operating to ensure that the tyre is removed from its corresponding mould part. The rings are then retracted to leave the tyre resting freely on the lower mould part 21, and the tyre is manually removed from the press. The next tyre to be vulcanized is then laid on the lower mould part 21, the pressure rings 18 are again advanced to engage the beads of the tyre, to centre the tyre in the mould and reduce its diameter. The mould is then closed by raising the lower platen 6 and the locking ring 24 is re-engaged. The curing bag is inflated, the rings 18 withdrawn, the dogs 50 retracted, the press opened, the latches 45 swung outwardly, and the dolly 38, supporting the mould, withdrawn from the press and transported to the vulcanizing station. The fluid pressure system for operating the press is described with reference to Fig. 13 (not shown).
