Title: Potential control funnel for HV cable junction box - has narrow end pressing elastic conducting sleeve onto conductive layer on cable
Inventor: GOEDECKE HANS-PETER DIPL-ING
IPC: H02G15/068
Filed: 1973-08-25
Abstract: The potential control funnel for the ends of a cable junction box fits over the HV cable with its narrower end and fans out at its broader end towards the centre of the tubular junction box. The narrower end presses an elastic, conducting sleeve against a conducting layer over the surface of the cable. The elastic sleeve consists of two or more wound, conducting layers arranged so that the narrower end of the funnel can slide between them. The conducting layers may overlap and may be of self-adhesing material. These layers may be also used for holding the funnel.

Title: Power semiconductor diode aluminium or zinc heat sink - has radial cooling fins forming arms of star coaxially enclosing cylindrical diode
Inventor: GOY DIETRICH
IPC: H01L23/40
Filed: 1973-09-26
Abstract: The heat sink for high-power semiconductor diodes consists of a cylindrical star enclosing the cylindrical, electrically insulated diode so that its arms form radial cooling fins parallel to the diode axis. Each fin is thicker at its base, i.e. where it joins the tubular part enclosing the diode. Two of the fins may be fused into one to form a crude base or mounting surface, whilst two other fins may have a slot between them extending down to the diode body. The heat sink has roughly the same axial length as the diode, and is made from aluminium or die-cast zine. A lead may be brough through the heat sink bore in parallel spacing with another lead.

Title: Reactor for photochemical reactions - has transparent cylinder around vertical rotor shaft with rotating wipers to distribute feed
Inventor: DUERR HEINZ PROF DR
IPC: B01J19/12
Filed: 1973-12-19
Abstract: A reactor for photochemical reactions consists of a transparent cylindrical vessel (esp. so far visible and UV light) surrounded by radiation sources. Down the central axis of the vessel is a shaft surmounted by a rotor with arms to which wiper devices touching the vessel walls are connected. A feed supply is located above the rotor with a run off device below the cylinder edge. The wipers create a continuous falling film over the cylinder surface. The rotor has a variable speed drive. A continuous reactor constructed on this principle has better film distribution than systems using a rotating vessel. The reagents can be recycled and precipitates removed. The film surface can have a protective inert gas atmosphere or one of the reagents can be a gas.

Inventor: HERSHBERGER DONALD FREDERICK
IPC: C12N9/48
Filed: 1974-04-22
Abstract: Microbiological rennin (MR) is isolated and purified by mixing an impure aqs. soln. of MR (e.g. a culture broth) at a pH of 3-4 (pref. 3-3.5) with a polycarboxylic acid, e.g. polyacrylic acid, a hydrolysed ethylene/maleic anhydride copolymer and/or a hydrolysed methyl vinyl ether/maleic anhydride copolymer, and separating the ppte. from the impurity-contg. soln.
