Title: Method of and an apparatus for marking metal objects
IPC: B21C51/00
Filed: 1979-04-25
Abstract: A method of and an apparatus for marking metal objects, especially metal billets at high temperature. The marking will enable selective identification of the object in question. A marking head (3) is utilized, having at least one electrode (4) for providing characters built up in a matrix form on the object (1) by means of an electric arc process. The characters consist of matrix parts in the form of welded-on projections, in which case a consumable electrode is utilized preferably in conjunction with the principles for gas metal arc welding, or alternatively of matrix parts in the form of recesses, in which case a non- consumable electrode is utilized, preferably in conjunction with the principles for plasma arc cutting. The marking head (3) preferably comprises a sequence of electrodes (4) which are activated selectively in conjunction with relative displacement between the marking head and the metal object (1) to provide the desired character matrix parts. By sensing that necessary electrode current has been consumed in conjunction with an activation of an electrode, a confirmation can be obtained that the desired character matrix part has actually been provided. <IMAGE>

Title: Radiation absorption distribution measurement in a part section of a body
IPC: G06T11/00
Filed: 1980-11-26
Abstract: If the absorption distribution in only a part, for example a separate organ, of a body section under examination is required, the overall radiation dose administered to the body can be reduced. The part region 11 is irradiated with the full intensity by a beam limited 11a 11b to the width of the region 11 during a first measurement cycle. In order to avoid reconstruction errors, the entire body slice 6 is irradiated during a second measurement cycle by a beam 9, 10 having a second intensity which is substantially lower than the first intensity. Thus, along each measurement path through the part region 11 of the body section 6 there are available two absorption values from which suitable correction factors can be determined for correcting all the absorption values measured with the second intensity and lying outside the region 11 so that errors with respect to the absorption values measured using the first intensity, can be corrected to reduce artefacts during the reconstruction. <IMAGE>

Title: Stabilization of Red Phosphorus
IPC: C01B25/00
Filed: 1981-03-27
Abstract: A method of protecting particulate red phosphorus used in smoke-producing compositions against atmospheric oxidation and hydrolysis comprises coating the phosphorus with a surface layer of a rigid thermoplastic material, preferably polyvinyl butyral. The coating is applied by mixing red phosphorus with the thermoplastic material in the presence of a solvent, eg dichloromethane, which softens or dissolves the thermoplastic, or by contacting the phosphorus with a solution or gel of the thermoplastic material, and evaporating the solvent. The resultant composition may also include an anti-oxidant added before or during the coating procedure. In addition to the protection granted by the coating, the rigidity of the thermoplastic layer allows the coated phosphorus material to be used as a filling in eg artillery shells and/or mortar bombs with a reduced risk of "set back" of the shell filling during firing from a gun.

Patent GB-2087668-A (GB)
Title: A method and an apparatus for the production of an alternating current from a direct voltage source
IPC: H02M7/56
Filed: 1981-10-27
Abstract: A circuit having many contact points (34) is provided between a direct voltage source (31) and the primary winding (33) of a transformer. The primary winding (33) is divided into specifically adapted winding sections according to the required alternating current form, each winding section being connected to a corresponding contact point. By scanning the contact points (34) with a brush (35), voltage pulses are successively produced in each winding section which induces the required alternating current (37) in the secondary winding (32). During this procedure, the frequency of the alternating current depends on the scanning speed of the brush (35). Alternatively, the current in the primary winding is chopped and the secondary winding is divided into a plurality of sections which are successively scanned. <IMAGE>

Title: X-ray generator including an X- ray tube provided with an intermediate electrode
IPC: H05G1/32
Filed: 1981-11-16
Abstract: An X-ray tube 1 has an intermediate electrode 4 connected to ground, the anode 2 and cathode 3 each being connected to a correspondingly grounded high- voltage generator 5, 7, which can be electronically and independently controlled. The tube voltage can be controlled by variation of the voltage of the high-voltage generator 5 connected to the anode 2. The tube current is measured by a resistance 9 and can be very quickly controlled 13, 14, 10 independently of the tube voltage, to match a reference 11 by varying the voltage of the high-voltage generator 7 connected to the cathode (e.g. increasing the negative voltage applied to the cathode 3 relative to the intermediate electrode 4, will increase the current, and vice-versa). The high voltage generators are supplied through converters 6, 8. This form of rapid current and voltage control can cause voltage unbalance about the intermediate electrode 4. However, the cathode voltage can subsequently be made equal in magnitude to the anode voltage by a slower-acting heater control circuit 25 acting initially via the tube current, which because of the rapid current control 13, 14, 10, returns the cathode voltage to a balancing value at the selected tube current. Alternatively the cathode voltage can be programmed (dashed line) via the heater control to lie at the centre of a desired rapid current- control range and for dose rate control. <IMAGE>

Patent GB-2101368-A (GB)
Title: Improvements in or relating to pulse actuated stepping motor driven electronic timepieces.
Inventor: ITO JIRO
IPC: G04C3/14
Filed: 1982-05-06
Abstract: A stepper rotor is driven with a narrow pulse width input which matches the load conditions on the motor. The subsequent position of the rotor is detected as being rotated or non-rotated by application of a detection pulse to the rotor. An additional driving pulse of increased width is applied should the rotor be found in a non-rotated state. A stabilizing pulse prevents intermediate rotor positioning. Position of the stepper motor is detected by passing a current through the rotor cell. The rate of increase in detection current is different when the rotor has rotated and when the rotor does not rotate because coil inductance and magnetic flux directions passing through the saturable portion of the stator are different depending upon the position of the rotor. The width of the driving pulse for normal operation is selected from a range of pulse widths so as to match the load on the motor.

Title: Shallow channel field effect transistor
Inventor: FEIST WOLFGANG M
IPC: H01L29/78
Filed: 1983-10-04
Abstract: A field effect transistor has an elongate buried region 30 of opposite conductivity to the semiconductor layer 12, formed below the gate electrode 44. The buried region which forms a bottom gate is electrically connected to the top gate electrode, where it breaks through to the electrode at the edges of the mesa layer. With this arrangement the channel of the FET has a shallow depth in the semiconductor between the gate electrode 44 and the buried layer 30. The top gate may be of the insulated, schottky or junction type. The FET is fabricated by forming a pair of masking strips 14, 16 of insulating material on the surface of the semiconductor, forming an ion implantation masking layer between the pair of masking strips and implanting particles to establish the source and drain regions 22, 24. With such method a single masking step is used to define the source, drain and gate regions of the device, namely the masking to define the strips 14 and 16. The buried layer is formed by deep ion implantation with the source and drain masked or without masking so that there is shallow implantation under the strips 14, 16 and deep implantation elsewhere. Gate oxide may be deposited between the strips before implantation. The device may be formed in a semiconducting mesa on a sapphire or similar substrate. <IMAGE>
