Title: Finishing pre-formed aperture in extrusion tool
IPC: B24B31/116
Filed: 1970-09-16
Abstract: Finishing an opening in an extrusion tool consists of mounting the tool in a holder and forcing an abrasive compound through the tool in the required extrusion direction. As it passes through the tool opening the compound abrades the side wall and the abrasion process is continued until the desired finish is achieved. Pref. the tool holder is positioned at one end of a cylinder containing a ram which forces the compound through the tool in a manner which simulates the extrusion process, i.e. the compound being extruded into a free space in to which it is not confined. Used in the extrusion of aluminium sections or for de-burring drilled passages in metal components. The apparatus eliminates the need for the usual hand finishing, providing a more uniform and accurate finishing without the use of skilled labour. - US3886697 A Finishing an opening in an extrusion tool consists of mounting the tool in a holder and forcing an abrasive compound through the tool in the required extrusion direction.

Title: Quenching hydrocarbon reaction prods - esp from pyrolysis, by introducing liq, forming a mobile film on the equipment
Inventor: FEJGIN JEWGENJI ALEXANDROWITSC
IPC: B01J10/02
Filed: 1972-07-28
Abstract: Products of hydrocarbon processing are rapidly quenched to prevent formation of by-prods. by adding a further liq. which forms a mobile liq. film on the surfaces surrounding the prod. The same liq. is pref. also added in dispersed form to restore the liq. film, which tends to be carried away in droplets by the high-velocity prod. stream. The pref. film-forming liq. are melts of metals, their oxides or salts, or mixts. of these. The process is esp. suitable for quenching of pyrolysis products e.g. in mfr of olefins. The mobile film prevents deposition of coke on the walls, so that stoppages of the plant for cleaning are reduced. Heat transfer is improved, so that the quenching rate is increased and yields of required prods. are improved.

Title: Piezoelectric surface wave filter - has symmetrical interdigital structure with specified electrode spacing and comb tine width
Inventor: DOLLWETZEL REINER DIPL-ING
IPC: H03H9/145
Filed: 1973-08-16
Abstract: A piezoelectric surface wave filter passes an amplified narrow frequency band and suppresses the undesirable sidebands without having to use differential lengths or widths of the comb electrode tines. This is achieved by arranging the axes of symmetry of the electrode systems on the piezoelectric carrier at a distance equal to an integral multiple of the wavelength of the main resonance frequency; the width of the comb tines is made smaller than one-quarter of that wavelength. The surface wave filter gives good performance but still is cheap to manufacture.

Title: Protection circuit for stalled DC motor - using electronic switching circuit dependant on motor voltage includes timer circuit
Inventor: ROECKNER KLAUS DIPL ING
IPC: H02H7/08
Filed: 1974-06-28
Abstract: The application is primarily to ventilator fan drives in motor vehicles. A power switching element is in series with the motor across the supply. By moving the control switch from the 'off' position current passes through a timing circuit switching the power elements on. If at the end of this timed period there is insufficient voltage across the motor terminals to actuate the secondary switching elements the flow of control current to the power switching elements ceases and the motor is turned off. Thus the motor is switched off if it is stalled or if the supply voltage is too low. The timed interval is chosen to allow normal run up of the motor and to prevent overheating of a stalled motor.
