Abstract: 1,255,680. Automatic voltage control. TORE SEEM ELEKTRONISK VERKSTED. July 31, 1969 [AugS, 1968], No.38513/69. Heading G3R. In a D. C. voltage regulator of the type comprising one or more transistors Q4, Q5 which are connected between an unregulated D. C. input V1 and a regulated D. C. output V0 and which are switched on or off by a control circuit including a driver transistor Q2 and load resistor R3, a parallel combination of an inductance L1 and rectifier diode D1 is provided to reduce the effect on the driver circuit Q2, R3 of variations in the voltage of the input V1. An explanation is given of the action of the circuit L1, D1 in maintaining the collector-emitter voltage of the transistor Q2 substantially constant during voltage variations of the input V1. To reduce the transition time between the conducting and non-conducting states of the transistors Q4, Q5, the resistor R3 is shunted by a transistor Q3 whose base is controlled by a feedback circuit R1, C1 and by pulses applied to a terminal A, these pulses being complementary to control pulses applied at a terminal A which latter pulses are produced by a conventional error determining circuit (not shown) of comparator and Schmidt trigger for controlling the transistors Q2, Q4, Q5 in the usual way. When control pulses are applied to terminals A, A, the feedback circuit R1, C1 delays the actuation of the transistor Q3 so that the transistor Q2 is made non-conductive before the resistor R3 is short circuited by the transistor Q<SP>3</SP>. Similarly, when the pulses are removed the short circuit is broken after transistor Q2 has been made conductive. Members D2, L2 provide load current during off periods of the transistors Q4, Q5. The components producing the fast transition time for these transistors may be omitted, Fig. 3 (not shown).

Title: Improvements relating to a tying machine
IPC: A22C11/00
Filed: 1967-08-22
Abstract: 1,147,484. Tying machines; endless conveyers. B. H. BUNN CO. 22 Aug., 1967 [7 Sept., 1966], No. 38708/67. Headings B8A and B8C. [Also in Division A2] Apparatus for use in tying lengths of twine round an article comprises a rotatable twine arm 12 and means for advancing the article intermittently towards the twine arm so that a number of separate spaced ties 23 may be placed round the article 22, Fig. 2. The article, which may be a roll of meat, is compacted and shaped before the application of each tie, and the operation of the machine is controlled by a system of electrical switches working automatically in response to a photo-electric device which senses the presence of an article. In operation, an article (not shown in Fig. 1) is placed on a support 29 and is advanced intermittently by one of a pair of pushers 61, mounted on endless conveyer chains 54 55, Fig. 5, through a pin clutch, Fig. 6 (not shown), towards twine arm 12, which is fed by twine 18 from a container 17 and is driven by a motor 11. When the article reaches a position in which it obstructs a beam 95 from a light source 9<SP>1</SP>, a photo-cell 93, Fig. 5, operates a relay (100), Fig. 9 (not shown), and now each time the article is advanced one step, an electrical switch causes a mechanism 67 to descend, clamping and shaping the part of the article to be tied, Fig. 7 (not shown). Whilst the article is thus held, a further signal causes a switch to depress a pedal 19, whereupon the twine arm 12 is rotated and a reach of twine is secured around the article (the means by which the twine is knotted is not described). The clamping mechanism 67 is now released in response to a further signal, and the article is advanced by another increment to receive the next tie. This cycle continues until the pusher 61 reaches the end of its travel and actuates a switch to halt the cycling. The article is now completely bound and may be removed and replaced by a fresh article. The article support and advancing means, and the control means may be adapted for attachment to a known machine such as that described in U.S.A. Specification 2,366,235.

Abstract: 889,729. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 18, 1960 [Dec. 21, 1959]. No. 39682/60. Class 37. A thin film superconductor is formed by depositing a strip of superconductive material upon a substrate and removing the edges of the deposited strip. In the arrangement shown in Fig. 2 a glass substrate 10 supports a superconductive shield plane 11 and a layer of insulating material 12. The shield is of a " hard " superconducting material e.g. lead and niobium. A layer 12 of silicon monoxide insulation is then deposited and a thin layer 13 of metallic tin or indium which acts as the gate conductor is deposited through a pattern mask. The section of this tin layer is shown in Fig. 3A and the portion to the outside of each dotted line is removed. This makes the transistion region narrower and steeper because, it is said, impurities and stress are concentrated in the edges. A further layer of insulation may be deposited on the substrate carrying a control conductor. Specification 862,178 is referred to.

Abstract: 1437750 Gasification of coal using molten iron USS ENGS & CONSULTANTS Inc 12 Sept 1974 [12 Sept 1973] 39860/74 Heading C5E Combustible gas is produced by injecting pulverized coal into a first zone of a bath of molten iron containing 1-3% dissolved carbon, thereby increasing the carbon concentration to 3-5%, contacting a second zone of the bath having a carbon concentration of at least 3% with an oxidizing medium selected from oxygen and steam, and collecting a mixture of hydrogen and carbon monoxide therefrom in a volume ratio of hydrogen to carbon monoxide of from 2 : 5 to 10 : 1. The coal is pulverized to an average particle size no greater than 30 mesh (U.S. standard sieve), is dried, and is injected pneumatically at a rate of 2À5-5 pounds coal/ minute/ton of iron in the bath. The first and second zones are separated so that molten iron may circulate from the low carbon zone in which carbon is injected to the high carbon zone in which oxygen and/or steam is injected. The oxidizing medium is injected beneath the surface of the molten iron. Oxygen is injected at a rate of 150-300 scfm./ton or iron in the bath. When the oxidizing medium is steam, the bath is heated by an electric furnace. The gas stream may be converted to high-purity hydrogen by shift conversion with steam and subsequent carbon dioxide scrubbing with monoethanolamine.

Filed: 1957-12-27
Abstract: 844,084. Computing gunsights. SOC. D'APPLICATIONS GENERALES D'ELECTRICITE ET DE MECANIQUE S. A. G. E. M. Dec. 27, 1957 [Dec. 27, 1956], No. 40209/57. Class 92 A computing gunsight system, including a sight 6 pivoted at 9 to rotate about an axis parallel to that of a rotatable gun support 2, is controlled by a member 7 whose deflection through an angle g from a neutral position turns the sight by means 8 to a proportionate angle relative to the gun 1 and rotates the support 2 by means 3, 4, 5 at an angular speed proportional to the sum of quantities proportional to the angle g and to its rate of change. Deflections corresponding to target movement are computed in both azimuth and elevation, but azimuthal systems only are described; one mechanical and one electrical. In the mechanical system a constant-speed motor 54 drives discs 53, 87c and 102c of variable speed drives 52, 87 and 102. Output cylinders 56 and 87a of drives 52 and 87 are coupled respectively to an input shaft 64 of a torque amplifier 66 and to a shaft 91 which moves the sight 6. The amplifier 66 rotates the gun-support 2 by the pinion 4 and rack 5. When the lever 7 is deflected.through the angle g it moves the ballcarriage 51 of the drive 52 correspondingly by a linkage 50 - 105 - 107. It also disturbs the ballcarriage 102b of drive 102 by linkage 108 - 104 - 111 - 110, causing cylinder 102a to rotate screw 109 and move link 104 on which link 108 is pivoted. A balance is reached and further motion of the link 108 ceases when the link 104 has been displaced by a distance proportional to dg/dt. This displacement of link 104 deflects a pivot-fork 116 on a link 115 through a link 113 whose pivot is displaced by a time-of-flight cam 96a which is set appropriately by a range-knob 98. One end of the link 50 is pivoted in the fork 116, so that the movement of ball-carriage 51 obtained from the other pivot on the link 50 is modified to the equivalent of g + Tdg/dt, where T is the time-of-flight: The same movement of the lever 7 is also conveyed through linkage 50 - 68 - 78 - 101 - 82 - 119 - 118, with similarly modification by a timeof-flight cam 96, to displace the ball-carriage 87b of the drive 87. This causes the cylinder 87a to move the end of the link 101, along a screw 92 and, with it, the pivot on the link 82 and the ballcarriage 87b. A balance is reached and motion of the shaft 91 ceases when a deflection proportional to Tdg/dt has been set on the sight 6. An electrical analogue of this mechanism is described and illustrated in Fig. 2 (not shown).
