Title: Improvement in or relating to semi-conductor devices
IPC: H01L29/00
Filed: 1955-07-29
Abstract: 800,300. Semi-conductor devices. STANDARD TELEPHONES & CABLES, Ltd. July 29, 1955 [Aug. 5, 1954], No. 21994/55. Class 37. [Also in Group XL (c)] A semi-conductor junction device comprises four adjacent zones of alternate conductivity types, one of the intermediate zones being electrically connected solely by its contiguity with the two adjacent zones, electrical connections being made to the said two zones and a further connecting means to the remaining zone, the latter being formed from said connecting means, in one of said two zones close to the intermediate zone. The arrangement provides a hook collector transistor. Fig. 1 shows a transistor comprising a germanium or silicon body having a hook collector N-type zone 2 and P-type zone 4, a base N-type zone 3 and an emitter P-type zone 8. Zones 2, 3 and 4 are produced by a growing process and zone 8 by welding a gold wire 7 containing acceptor material such as indium or gallium to base zone 3, by means of an electric pulse. The collector zone 2 is preferably of low resistivity material (0.1 ohm cms.) and the base zone 3 of higher resistivity (2 ohm cms.). Fig. 3 shows two such devices employed in a two-stage counter circuit, which may form part of a ring counter. The device has a current amplification factor greater than one, and each stage constitutes a bi-stable flipflop circuit. A positive pulse to the emitter of stage one via capacitor 12<SP>1</SP> switches the circuit to the first stable state with stage 1 ON and stage 2 OFF. A negative input pulse triggers the circuit to the opposite condition. The arrangement avoids the usual arrangement of two normal type junction transistors for each stage. Specification 795,113 is referred to.

Title: Method and apparatus for the preservation of forage
IPC: A23K3/00
Filed: 1965-05-25
Abstract: 1,114,213. Freezing forage. E. D. RAZUM. 25 May, 1965, No. 22064/65. Heading F4H. Freshly harvested forage is cooled by evaporation of moisture contained in the forage and subsequently frozen by contact with a heat-abstracting surface. As illustrated chopped forage is supplied direct from a harvester to a pipe 11 and is blown by a blower 12 along a wide passage 14 provided with helically arranged fins 15. Impact of the forage on the fins liberates water and evaporation of the water cools the forage and the condenser 17 of a compression - condensation refrigeration system. If a flap 50 is set as illustrated forage is deflected from the passage 14 and passes between rollers 46, 47 to passages 34 between rotating steel fingers 33. A number of sets of fingers are provided, each integral with a generally cylindrical member 30 which is rotated by a motor 61, Fig. 4b (not shown). The sets of fingers are separated by fixed hollow discs 38, Figs. 4a, 4b, 5 and 6 (not shown), which form the refrigerant evaporator, and freeze the forage during travel through passages 34. At the inner end of the passages 34 the forage is cut by knives 44 and removed by a screw conveyer extending axially through central openings in the evaporator discs. The temperature of the frozen forage is sensed at 58, Fig. 4b (not shown) and if the temperature is too high the motor 61 is stopped and the flap 50 adjusted to pass the forage to a hopper 24 in which angle-irons 28 moved by chains 26 and 27 tend to distribute the forage in the hopper towards the front of the apparatus (out of the plane of the illustration). A distributer 23 passes the forage for recirculation to the blower 12, the fins 15 again guiding the forage to the back of the apparatus. Each evaporator disc 38, Figs. 5 and 6 (not shown), comprises a hub 39 having holes 40 and 64a which are aligned in the assembled apparatus. Refrigerant is supplied as liquid through the holes 64a and leaves as gas through the holes 40 which communicate with the upper part of the interior of the discs through passages 42.

Title: Temperature compensated video signal processing circuit with a video signal clipping device
IPC: H04N5/16
Filed: 1975-05-22
Abstract: 1491125 Signal clipping TOKYO SHIBAURA ELECTRIC CO Ltd 22 May 1975 [30 May 1974] 22111/75 Heading H3T A signal clipping circuit, particularly for a D.C. restored video signal, and intended for monolithic integration, is so arranged that the clipping level is stabilized against temperature variations without, as a consequence, introducing any overall change in D.C. level. The input signal is amplified Ql, Q2 and clipped by Q3 connected as a diode, the clipping level being set by an emitter-follower Q4. This arrangement stabilizes the clipping level by maintaining the non-signal voltage across Q3 constant. For example, a rise in temperature causes both a rise in potential of the output of the emitter follower Q4-thereby tending to raise the clipping level by an amount e, say-and a fall in the baseemitter drop across Q3-thereby tending to reduce the clipping level by the same amount e. However this method of stabilizing the clipping level does change the D.C. level of the clipped signal. Thus in the example considered, the D.C. level of the clipped signal appearing on the emitter of Q3 is raised by an amount e. This variation is removed by introducing a corresponding variation in the output T3. As shown the clipped signal from Q3 is amplified Q5, Q6 by unity and put out via an emitter follower Q8, the corrective D.C. shift of the output being introduced by Q7. Thus, suppose as in the example, that a temperature change has increased every emitter-base voltage by e. Then working forward from the output of Q3, first the base of Q5 is raised by e, therefore the emitter of Q5 is raised by 2e, therefore the base of Q6 is raised by e and therefore the base of Q7 (and hence the output T3) is unaffected. Q7 could be replaced by a diode.

Abstract: 1,173,354. Ionisation manometers. POLITECHNIKA WARSZAWSKA. 15 May, 1967 [17 May, 1966], No. 22409/67. Heading HID. In order to minimize the effects of stray radiation on the measurements obtained from an ionization vacuum gauge, the gas which is ionized is shielded from extraneous radiation by being enclosed in a chamber whose perforated walls 1, 2, 3 form the anode between which and a cathode 5 ionizing electrons flow. The ions then pass through an aperture 4 in the anode wall 3 and are collected by collector 6. To minimize photo-electric emission from the collector, induced by X-rays from the anode and ultra-violet radiation from the cathode, the collector is made small. Further shielding may be provided by inserting a solid shield (10), Fig. 3 (not shown), with an aperture corresponding to the aperture 4 between the anode wall 3 and the collector. Alternatively the anode wall 3 may be made of solid metal, Fig. 4 (not shown), and provided with a further shield (12) displaced from but covering the aperture 4. These shields may be connected to act as suppressor or modulating electrodes. To increase the sensitivity of the collector 6, it may be provided with a shield 7 of solid metal, mesh, or glass.
