Patent DE-2518279-A1 (DE)
Title: Inductive ferrite core module - with helix produced by laser beam on coating and selective etching in copper layer
Inventor: HENTSCHKE PETER DIPL PHYS
IPC: H05K3/02
Filed: 1975-04-24
Abstract: The parent patent described an inductive module such as a choke coil or transponder produced by coating a ferrite core by a copper layer and by separating this layer into a helical winding by means of a laser beam. In this addn., the copper layer is followed by a film of high reflectivity and electrical conductivity and/or low melting point (Au, Pb or Sn). The laser beam erodes the film and the exposed copper layer is removed by selective etching. This saves the time-consuming and expensive laser operation for the bulk of the work and replaces it by an inexpensive chemical mass production method. The method is suitable for modules with any shapes of cores, including rectangular cores.

Title: Multilayer curtain coating tool - with slots chamfered on downhill edge to inclined sliding surfaces
Inventor: ADE FRANK
IPC: B29C48/07
Filed: 1975-05-16
Abstract: A tool for use in the curtain casting system of several layers, for example for the coating of carrier materials with photographic emulsions, includes vertical supply ports, horizontal distributor bores and vertical feed slots. The latter end in inclined sliding surfaces. The downhill edge of each slot is chamfered, with a chamfer width from 0.5-5 mm and with a chamfer angle to the sliding surface of 100 to 170 degrees (110-140 degrees). This saves having to raise the uphill edge of each slot and prevents any uphill overspill of the coating material more reliably. Any desired number of layers can be applied, without difficulties caused by changing this number.

Title: Peristaltic pump for fluids - has travelling compression members lifting away from hose when returning against pumping direction
Inventor: DIEFENBACH GUENTER
IPC: F04B43/12
Filed: 1975-06-05
Abstract: The pump comprises a compressible hose (2) and a rotating pump element (1, 1') carrying a number of hose-compressing members (3) which, in operation, compress the hose whilst travelling along it in the pump flow direction (F).

Title: Casting-resin plug mfr. for pressurised telecommunication cables - using mould with closure preventing discharge of resin
Inventor: GANSER ALFONS ING GRAD
IPC: H02G15/24
Filed: 1976-03-03
Abstract: Mfr. of a pressure-tight plug, made of a casting resin, for longitudinally sealing pressurised cables, especially telecommunication cables protected by pressurised gas, uses a suitably shaped mould with a closure preventing discharge of the resin. The continuously extending line elements are shaped near the sealing region and provided with spacers.

Inventor: RAYMOND ANTHONY JOHN
IPC: C23C2/38
Filed: 1976-08-06
Abstract: In applying a molten metal coating to a metal tube or other workpiece, the metal flows over the workpiece from a reservoir and a splash plate, pref. in the form of a tube, is provided to direct the flow around the workpiece. The splash tube is connectd to a reservoir to receive the molten galvanising material from slots or apertures in the reservoir.

The coating reduces or eliminates false readings due to the presence of reducing substances other than alcohol in the breath. The breath of diabetics can have an acetone : ethanol ratio of ca 1:5. Coating of the sensor can reduce its sensitivity by a factor of 10, so that errors due to acetone become negligible. The material which changes its conductivity in contact with reducing substance pref. contains one or more metal oxides. The coating material is pref. water-soluble and hygroscopic, examples of suitable substances being beta-alanimine, benzyl benzoate, 8-hydroxy-5-quinoline-carboxylic acid and aluminium chloride.
