Title: Oscillator for inductive initiators - has coil system with two terminals and capacitor as oscillating cct
Inventor: BEUTHNER KLAUS DIPL ING
IPC: H03K17/95
Filed: 1975-06-18
Abstract: The oscillator comprises an amplifier stage followed by a phase inverting stage, whose output is connected through two feed-back circuits to the amplifier input.

Title: Parting off extruded profiles, esp. plastic pipes - by rotating cutter pressed on intermittently to form very short cuttings
Inventor: HEILAND WILHELM
IPC: B23B5/16
Filed: 1975-11-22
Abstract: Profiles, esp. pipes of thermoplastic material are parted off by means of a rotary cutter which during the operation is fed forward intermittently against the profile surface. The feed of the cutter is effected by a continuous drive through a transmission, and there is a mechanism which interrupts the feed at intervals. Prevents the development of long cuttings which twist around the tube end and have to be removed. The flow of work through the plant is thus speeded up.

Title: Double-walled article partic. double glazing unit prodn. - from thermoplastics sheets spaced apart then pressed together inside frame
Inventor: HAZELWOOD COLIN MILES
IPC: B29C49/00
Filed: 1975-12-30
Abstract: Method comprises first clamping a pair of thermoplastic sheets or plates onto opposite sides of a spacing frame, so that a space remains between them; heating one or both sheets, either before or after clamping to the spacer, to a temperature above the softening point of the material. A pair of all-round clamping frames is then applied onto the outer faces of the sheets and within the periphery of the spacer frame, after heating, with a sufficient press. to bring the two sheets into contact with each other along a strip, thus bonding them together along this strip. The softened sheets are strained relative to each other, so that one or both of them becomes curved. Pref. before the two sheets are mounted on the spacer frame, an adhesive strip is laid along one of them on its inside face, in a pattern corresponding to the intended bonding line. Used partic. for the shaping of special double-glazing or insulating windows, roof-lights and the like. The use of a spacer between the thermoplastic sheets prevents them from sticking together in undesired regions; intentional bonding along the desired strip is partic. facilitated by the use of an adhesive strip.

Title: Concrete remains processing plant - uses single vertical conveyor and four gravity operated separating zones to reclaim basic ingredients
Inventor: RIKER RUDOLF ING GRAD
IPC: B03B9/06
Filed: 1976-10-19
Abstract: The plant can be used for processing concrete remains and refuse material occurring in works producing finished building elements, to reclaim the basic materials such as sand, cement and water for reuse. The silo unit rests on three legs, two of which serve at the same time as guide rails for the charging container conveying the material to the top of the silo, where it is emptied into an intermediary buffer and distributing assembly. The material flows into the multi-stage sifting section which can be either a linear or circular sieve. The solids are discharged from the shell of the silo and the fine and floating materials flow downwards over a conical bottom. Clear water leaves the installation as an overflow via a ring trough and discharge pipe. The last zone consists of a cone-shaped, sludge-settling section with agitator and discharge opening.

Title: Adjustment of electronic coin testers - supplying coin of average wear balancing test circuit and then using new minted and well worn coins to set acceptance limits
Inventor: KAUFMANN BENNO DIPL ING
IPC: G07D5/00
Filed: 1976-11-29
Abstract: The tester distinguishes perfect circulation coins from foreign and counterfeit coins. It has a bridge circuit responding to an impedance change, and an additional resistor determining the evaluation threshold. A selected coin whose parameters lie at about the middle of permitted tolerances for acceptable coins, is supplied to the tester and held in the middle position after adjustment of the mechanical zero point in the probe coil (L2).
