Title: Billet shearing and marking apparatus and method of shearing and marking billets
IPC: B44B5/02
Filed: 1971-08-12
Abstract: 1365561 Shearing; marking USS ENGS & CONSULTANTS Inc 12 Aug 1971 [17 Aug 1970] 37963/71 Headings B3W and B3Q Elongated stock 12, such as a continuouslycast billet, is sheared into billet lengths 32 by a reciprocatory shear having a movable blade 70 and a stationary blade 60, a device 80 on one or both of the blade assemblies 56, 58 marking the stock during shearing. In a flying upcut shear, Fig. 2, both blade assemblies are mounted on a carriage 38 which is reciprocable along rails 42, 46 by means of an hydraulic cylinder 50. A support table 90 driven along the rails 42 is pivoted to the blade assembly 58 to rise with it when an hydraulic cylinder 86 is actuated. A hold down 110 yieldingly resists upward movement of the blade assembly 58. Front and rear crop scrap shoots 118, 120 are provided, the latter being raised by a cylinder (not shown) to act as a stock support until the tail of the stock approaches the shear. The stock is fed through the shear by rolls 76 or 132 and 24 and guided by a flared tube 74. Four cast strands 12 fed side-by-side from a mould (14) Fig. 1 (not shown), through straighteners (18), (22), furnaces (26) and reduction mills (28a and 28b) are fed to shear where the strand number is marked on each strand by, e.g. parallel rods (82), Fig. 6 (not shown), letters, figures &c., Figs. 13-15 (not shown). Billets leave the shear 30 along paths L1-L4, billets in paths L1 and L4 activating sensors 142 which cause pushers 146 to move those lengths close to paths L2 and L3 respectively. Rollers 24 move the billets to further sensors 142a associated with stops 154 which are moved out of the feed path to release lengths in a predetermined sequence for delivery via a fixed stop 143 and a feed table 126 to a station 158 for further marking at 160 and discharge on rollers 24. The blades may be shaped to embrace one or several bars of circular cross-section, Figs. 12a and 12b, a marking device being mounted in each bar recess. The shear path may be at 45 degrees to the vertical, (Fig. 11, not shown).

Title: Automatic cranking systems for motor vehicle internal combustion engines
IPC: G01P3/48
Filed: 1972-08-17
Abstract: 1380483 Starting prime movers GENERAL MOTORS CORP 17 Aug 1972 [1 Sept 1971 (2)] 38406/72 Heading H2H A system for automatically cranking the engine of a motor vehicle comprises a starter motor, an engine speed tachometer and a vehicle speed tachometer, the system being so arranged that, independently of the normal starter motor circuit, the starter motor is energized when the engine speed is below a predetermined minimum speed and the vehicle speed is above a predetermined speed. The wheel speed of a vehicle is sensed by a rotating magnet 32 operating a reed switch 26 so as to produce voltage pulses which charge a capacitor 42 such that at a predetermined vehicle speed the charge on the capacitor 42 is sufficient to cause a bi-stable pair of switching transistors 46, 52 to assume a state in which the output voltage at the collector of transistor 52 is high, this voltage being applied to the base of a transistor 106 in a gate circuit 22. The speed of the engine of the vehicle is sensed by applying the pulses which occur at the primary winding 58 of the vehicle ignition coil 59 when the contact breaker 60 opens to a capacitor 90 by way of a transistor 66 so that the capacitor 90 receives a charge depending on the speed of the engine. When the capacitor 90 is charged sufficiently it causes a bi-stable pair of switching transistors 94, 100 to assume a state wherein the output voltage at the collector of the transistor 100 is high, this voltage being applied to the base of a second transistor 108 in the gate circuit 22. When both transistors 106, 108 are non-conductive a transistor 112 is conductive to energize a relay 114 which closes a contact 116 to energize the starter solenoid 118 so as to crank the engine; the transistors 106, 108 only being in their non-conductive states when the output from transistor 52 is high and the output from transistor 100 is low respectively. Thus the starter solenoid can only be energized when the vehicle speed is above a given speed and the engine speed is substantially zero. Normal engine starting is effected by closing the PARK and NEUTRAL safety switch 121 and the starting switch 122. In a second embodiment the voltage signals obtained by the vehicle and engine speed sensors are of opposite polarities, the sum of the signals being used to control the gate 22.

Title: Improvements relating to generating stepped voltages
IPC: H04N9/27
Filed: 1967-08-22
Abstract: 1,203,084. Converting. INTERNATIONAL POLAROID CORP. 22 Aug., 1967 [22 Aug., 1966], No. 38561/67. Addition to 1,124,873. Heading [Also in Division H3-5] A three-level stepped wave is produced across the capacitance of a resonant circuit by supplying or subtracting energy to or from the capacitance while the resonant frequency is momentarily increased. Fig. 1 shows a N.T.S.C. colour television system of the line sequential type in which the different colours are produced by applying different values of EHT voltage to the tube to thus control the depth of penetration of the electrons into the three-colour screen. The EHT voltage is provided by adding to the steady EHT voltage at 47 a stepped wave produced across winding 56a. When a thyristor 61 is fired a low impedance voltage source 49 is connected across the primary winding 56b. This effectively short-circuits the winding and so raises the resonant frequency of the circuit formed by the secondary winding and the capacitance 57. A half-cycle of oscillation takes place rapidly raising the voltage across the secondary capacitance. The primary current flows into a capacitor 60 and when this is charged the thyristor extinguishes. The resonant frequency is thus returned to a low value and the capacitance voltage is maintained. At the beginning of the next line, thyristor 62 is fired and a further step is likewise produced by a connection to a higher voltage source 48. At the third line, thyristor 63 is fired to discharge the capacitor 60 and return the output steeply to the initial step value. Separate charge and discharge primary windings may be used (Fig. 6, not shown) or separate windings may be used for each step (Fig. 4, not shown). In Fig. 5 (not shown), the output circuit is charged in one step and discharged in two, the first being a discharge into a capacitor (98). Transistors may replace the thyristor and an autotransformer may be used to replace the conventional transformer. The step levels and durations may be varied. The firing pulses for the thyristors may be derived from an oscillator/divide-by-three circuit (74, Fig. 3, not shown), the output pulses of the oscillator feeding the gate of the first thyristor and also a multivibrator delayed pulse generator feed the second thyristor. A delayed pulse from this is further delayed in another multivibrator and feeds the third thyristor. These pulses may also control the gating of respective colour signals to the control electrode of a single beam tube or alternatively gate the appropriate beam in a three-gun tube.

Title: Improvements in or relating to the treatment of metallic melts
IPC: C21C5/46
Filed: 1958-12-05
Abstract: 901,360. Refining metals. FISCHER A.G., GEORG. Dec. 5, 1958 [Dec. 6, 1957], No. 39337/58. Classes 72 and 82 (1). A method of treating a metallic melt to control the gas content and carbon content simultaneously comprises pouring the melt into a tiltable and transportable hermetically sealable container, closing the container, reducing the pressure, introducing a treating gas into the container and, after reacting gas and metal, replacing the treating gas with a protective gas and, if desired, adding alloying constituents to the melt. As shown, container 1 has a lid 4 sealed at 6 and an induction heating coil 10, or it may be heated by an electric arc. Line 13 is connected to valve 18 which selectively leads to vacuum line 14 or to gas supply line 16 from generator 15, and at its other end leads to ducts 17 between the refractory lining 2 and shell 3 of container 1 and to suction opening 19 above the melt 9. Separate outlets for slag and metal may be provided (Figs. 3 and 4, not shown). After charging, the lid 4 is closed and the container evacuated to a pressure of 200-50 Torr. During evacuation the melt boils and evolves occluded gas. At the same time a treating gas such as N 2 , CO, H 2 O, CO 2 , NH 3 , CH 4  or homologues thereof, or mixtures of these gases diluted with rare gases may be introduced, or it may be advantageous to build up and reduce pressure repeatedly. The treating gas may be used to control the carbon, or nitrogen content of the melt within fine limits. When the melt has reached the desired composition, the treating gas may be pumped out and replaced by a protective gas such as a rare gas, CO, N 2 , H 2 , or CO 2 , present in such proportions as to be in equilibrium with the melt or to recarburize it to a desired degree. This gas may be produced in a gas generator 15 supplied with oxygen and carbon dioxide, and a fuel low in sulphur and bitumen such as charcoal. The treating and protective gases may be dried by circulation through a drying column. Alloying additions may be made after the completion of the boiling process, a slight over-pressure of treating or protective gas being maintained while a cover is removed. The melt may be pre-refined in the container before closure by means of oxidizing gases or solids, and when treated it may be cast through a tube filled with a protective gas.
