Title: Travelling wave tube - using tungsten-copper vacuum sheath surrounding beryllium oxide bars holding delay line, and thus minimising thermal stresses
Inventor: GROSS FRANZ DIPL ING DR
IPC: H01J23/26
Filed: 1978-09-04
Abstract: Tube includes an outer metal vacuum sheath or tube contg. a delay line located between an electron beam generator and an electron beam collector. The delay line consists of a coil. or a ring-web configuration, and is located in tube by several bars made of dielectric material and in good thermal contact with the tube. Tube is made of a material which has a coefft. of thermal expansion very similar to the material employed for the bars. Bars are pref. of Be oxide, and the tube is pref. of a W matrix filled with Cu. The delay line is pref. made of Cu, Mo, or W. By using materials with similar coeffts. of thermal expansion for the bars and tube, the danger of cracking the bars, esp. during initial baking of the tube, is eliminated.

Title: Ultrasonic weld test assembly - uses separate transverse and longitudinal fault detectors to achieve close packing
Inventor: REHME WILFRIED
IPC: G01N29/26
Filed: 1978-09-16
Abstract: The ultrasonic test assembly provides an automatic interference free detection of transverse and longitudinal weld faults. Four transverse fault test heads (1, 3, 4, 6) are positioned at the corners of an X over the workpiece weld (16). Two longitudinal fault test heads (2, 5) are actuated opposite to each other across the weld. The workpiece (15) is passed under the detector assembly. The separation of the transverse fault detectors from the longitudinal fault detectors enables a closer packing of the test heads. thus welds in thin walled sheet or tubes can be accurately scanned.

Inventor: NISHIKAWA MASAJI
IPC: G03G15/22
Filed: 1978-11-20
Abstract: An electrostatic copier produces the copy on a resin copy material which is heat sensitive. A latent image of the original document is produced on a drum (11) and developed by a toner. The toner image is transferred to the sieve like surface (1) of a copy material (3) with a resin sandwich layer (2).

Title: High tensile spring steel - is subjected to repeated surface induction heating to obtain extremely small grain size and increase fatigue strength
Inventor: HIJIKATA TOSHIO
IPC: C21D9/02
Filed: 1978-11-25
Abstract: The fine grain size of steel decreases progressively from its core to its surface, this structure being obtd. by brief repeated high frequency induction heating of the surface of the steel so through heating is gradually achieved. The steel is then quenched, followed by tempering using high frequency induction heating; and the steel pref. contains >0.3% carbon. Each brief heating cycle pref. raises the surface of the steel to above the Ac3 transformation point and is followed by a pause in which the surface drops below the Ar1 transformation point and the cycle is repeated at least twice so the steel is heated right through, or nearly right through, to the centre of the core. The treatment increases the strength, toughness, and fatigue strength of the steel, so it is suitable for coil springs, torsion bars etc.

Abstract: The finger bar having the mowing cutter (4) possesses a plurality of cutter holding-down devices (15) which are arranged along the bar (1) and which each press on to a sliding plate (14) fastened to the cutter (4), so that the front cutter bezels (10) slide free of play on the sliding faces of the fingers (2), the said sliding faces being provided with the counter-bezels (12). During operation, the pressure faces (17) of the holding-down devices (15) and the surfaces of the sliding plates (14) sliding on these undergo pronounced wear, so that the holding-down devices (15) regularly have to be readjusted. For this purpose, each holding-down device (15) is supported at its rear edge (18) on the bar (1) in a vertically pivotable manner by means of a downwardly projecting web (19), and guided through the longitudinal centre of its rear part is a stay bolt (21) which connects a finger end (22) to the bar (1) and which carries a nut (25) pressing the holding-down device (15) on to the sliding plate (14). For securing against rotation, the holding-down device (15) has two lateral holes, into which project the screw heads of two fillister-head screws (26, 27) connecting the adjacent finger ends to the bar (1). The finger bar can be used for all finger-type mowing units. <IMAGE>

Patent DE-2908363-A1 (DE)
Inventor: GASS ALBERT EDWIN
IPC: H02H7/20
Filed: 1979-03-03
Abstract: Failsafe primary power control apparatus is provided which includes a backside contact of a control relay in series with the power relay which is held open until the initial program load and latch reset is finished. The system also includes a timer which is initiated by a power fault condition signal which is simultaneously applied to the processor. If the processor is capable of handling the fault condition, it puts out a signal which stops the timer. If the processor is not capable of handling the fault, the signal to the timer is not produced and, accordingly, the timer runs the full interval. This causes the backside contact of the control relay to open thus deenergizing the power relay and removing the power from the entire system.

Title: Yarn carrier for forming dyeing package - is made of needle felt material as a seamless tube
Inventor: WINSON MICHAEL ADRIAN
IPC: B65H75/18
Filed: 1979-03-16
Abstract: Carrier on which yarn can be wound to form a package for dyeing is made of needle felt material, and is in the form of a seamless tube. The fibres of the needle felt material are partially bonded to each other, and the surface of the sleeve is calendered. The seamless carrier tube may be produced by feeding a web of fibres (pref. polyolefin) onto a tube forming means to form a fibrous tube, and then needling the tube to form a tubular seamless needle felt. The needle felt tube may be subjected to a heat treatment to improve its dimensional stability, and the tube can be subjected to a further heat treatment in which partial fibre bonding occurs. The dimensional stability and the snagging of the yarn is reduced compared with the seamed tube where the yarns can be entangled and the tubes can be split.

Patent DE-2916726-A1 (DE)
Inventor: THEVIS PAUL
IPC: B05B9/01
Filed: 1979-04-25
Abstract: The apparatus has a fluid reservoir (3) and a pressure generator by means of which the fluid can be pressurised. Connected to the reservoir is a blast pipe (4) having a trigger system which opens a valve. In order to be able to fire limited quantities of fluid in a deliberate manner over a range of more than only a few metres, a force store in the apparatus can be stressed by the trigger. The force store is initiated towards the end of the triggering movement and its movement is transmitted to the valve in order to open said valve. In the case of at least one operating mode of the trigger system, opening the valve initiates a timing element, and the closing movement of the valve is controlled by the timing element when its time interval elapses, irrespective of the position of the trigger. The apparatus is particularly suitable for police use of tear gas. <IMAGE>

IPC: B23K9/09
Filed: 1979-06-02
Abstract: Thyristorised inverter with a dc link for arc welding supplies applies its voltage and current through regulator and dividers with variable resistors to a voltage regulator and a current regulator. The no-load voltage and the short-circuit current of the rectifier are fixed thereby. The working point on this characteristic is adjusted by varying the inverter frequency which is controlled by the current regulator output voltage.
