Title: Current transformer short circuiting device - has impact bolt released by arc heat melting soldering fixture after short preset time
Inventor: KRAEFT HEINZ DR ING
IPC: H01T1/14
Filed: 1976-04-21
Abstract: In order to prevent dangerous voltage peak generation in open current transformer secondary current, a secondary circuit closure is provided to actuate a delayed desoldering of a short circuit impact bolt owing to the light arc generated heat. The short circuiting impact bolt can be regenerated by use of a soldering iron. Preferably the system contains bimetal strips which bent under the heat generated by the light arc, which provides an alternate short circuiting with resettable relocking. Between the secondary terminals (1) the sort circuiting impact bolt (3) is secured on two angle irons (2) and soldered at one of them at the angle iron rear (6). The bolt is prestressed by a spring (4).

Title: Measurement of mean coarseness of workpiece surface - using length gauge generating voltages corresponding to surface peaks and valleys
Inventor: KREIENSEN KURT
IPC: G01B7/34
Filed: 1976-05-12
Abstract: The measurement of mean coarseness of a workpiece surface is made by scanning using an electrical length gauge passed over the tested workpiece surface divided in e.g five measurement sections. It generates voltages corresponding to the surface peaks and valleys. Difference between highest peak and lowest valley in each section is formed by a summating device, and a device forming mean values is provided. Difference voltages corresponding to the coarseness of the n sections are consecutively added to the previously obtained sum, and the mean roughness of the surface is determined by dividing the sum total by n.

Title: Magnetic mechanical fastener for brief cases - fastening tab slides into fixed part of catch, magnetic disc is drawn into recess
Inventor: MARBACHER STEPHAN
IPC: A45C13/10
Filed: 1976-06-23
Abstract: Brief case fastener combines prompt and positive closing of a magnetic catch with a mechanical restraint which holds it against movement at right angles to the magnetic force. When the fastening tab (2) is slid into the fixed part of the catch, the magnetic disc (3) it carries is attracted to a ferro-magnetic plate (9): the disc is thus drawn into a recess (3'). The tab (2) cannot now be withdrawn until it has been pushed flat against the face of the brief case; it can then be slid out upwards. The space in which it moves is purposely restricted so that it can only be freed by these two deliberate movements in perpendicular directions.

Title: Four-legged chair with crossbeams - has two tension belts securing beam ends fitted in leg recesses
Inventor: HARTMANN HANS-MARTIN
IPC: A47C3/00
Filed: 1977-06-10
Abstract: The ends of the two pairs of crossbeams (6) of the chair fit horizontally into suitable recesses provided in each two adjoining chair legs (1, 2, 3, 4). Each pair of parallel crossbeams are associated with a belt which holds the beams firm in the recesses. At least one belt loops round all four beams. The beams and legs are thus held together only by the slot-in connection via the recesses and by the belts without the need for screws, glue, etc. The tension direction of each individual belt runs at right angles to each beam which it spans but parallel to each beam which it secures. Since the connecting points are no longer rigid they allow the seat to adapt to body movements providing greater comfort.

Title: Fluid container gas filling system - lifts inner vessel to deliver gas via annular gap
Inventor: GALIA KARL
IPC: B65B31/00
Filed: 1977-06-23
Abstract: The system fills with a gas receiver accommodating fluid or paste under pressure and dispensing it. the receiver comprises a rigid cylindrical outer vessel with a cover acting as valve mounting, together with an elastic inner vessel and a discharge valve in the cover. The inner vessel edge is clamped between the cover and the vessel neck and secured by an expander tool, after which gas is delivered into the space between inner and outer vessel. After filling the inner vessel, this is lifted so as to form an annular gap (22) between it and the edge (14) of the outer vessel (12). Gas is delivered into the space between the vessels through this gap, after which the inner vessel is lowered and its neck (20) clamped between the edge of the cover and the outer vessel.

Title: Control system for arc welding machine - has probe following line of weld with transducers to control path of electrode
Inventor: EDWIN ALLAN I
IPC: B23Q35/127
Filed: 1977-07-21
Abstract: An arc welding machine has a bed plate (17) with a sliding worktable (14) driven through a screw (28) by a motor(30). TWo vertical columns (20) support a cross beam (34) which carries the welding head (40). The welding head can move along the cross beam by another lead screw (36) driven by another motor (38). The welding head can pivot about its vertical axis and its angular position is measured by a transducer (43) mounted in the support (42). As the stylus (46) follows the line of the required weld between the workpieces (16), the transducers transmits signals to a circuit which controls the motors and so ensure that the welding electrode follows the correct path.
Patent DE-2737449-A1 (DE)
Title: Telescopic arm for reactor pressure vessel inspection - has rigid curved section steel tape as push and pull drive with frequent supports to prevent buckling
Inventor: SEIFERT WALDEMAR ING GRAD
IPC: B66C23/687
Filed: 1977-08-19
Abstract: A telescopic arm has an extension apparatus consisting of a steel tape or curved cross-section and a drive mechanism for extending or retracting the steel tape. The outer end of the arm carries inspection equipment for reactor pressureve sels. At intervals along the length of the arm, the steel tape passes through guide blocks, which fit its curved cross-section and are of sufficient length, in direction of tape length, to provide a clamped sliding action so that the tape is effectively fixed within each guide block. This improves its resistance to buckling to enable it to transmit high thrusts. The reeling mechanism passes the tape, when the arm is being retracted, through a nozzle-type block in which the tape is flattened so that it can be wound onto a reel.

Title: Device for checking correctness of component assemblies - uses steel ball with two stable positions, controlling air jets
Inventor: BARON WOLFGANG
IPC: B07C5/34
Filed: 1978-06-23
Abstract: A device for checking the correct assembly of a component consists of a housing (1) of transparent plastics with an internal channel (5) in the shape of an inverted U. A steel ball (6) which can roll in the channel (5) has two stable positions, one at each end of the channel. When a component is correctly assembled it automatically directs a jet of air to the thole (5b) so that the ball (6) is moved. An incorrect assembly causes air to flow through the hole (5a) which moves the ball which, in turn, actuates the magnetic switch (9) to shut down the assembly machine.

Title: X=ray converter screen - of improved performance by heating after polishing for reduced surface roughness of photocathode substrate
Inventor: ROEHRICH HEINZ
IPC: H01J9/12
Filed: 1978-07-21
Abstract: X-ray converter (intensifier) screens are produced by vapour deposition of the phosphor on a substrate to form a luminescent layer. The surface of the latter is ground, polished and heated for several hours to over 200 degrees C. Finally the photocathode is applied to the surface. The greatly reduced surface roughness which is achieved by the intermediate heating results in the reception of sharply defined images at a low radiation stress by a combination of high voltage and small input/output screen distance.
