Patent DE-2633178-A1 (DE)
Title: Photoelastic accelerometer with laser stabilisation - uses dual channel comparison for interference suppression
Inventor: HOLZAPFEL WOLFGANG DR ING
IPC: G01P15/093
Filed: 1976-07-21
Abstract: The accelerometer with laser stabilisation comprises a pair of parallel optical measuring oscillators and a photoelastic block operating as an acceleration transducer. The laser-excited beams are of different frequency and polarisation. By means of beam splitters and polarisation filters, the two channels are separated optically and compared with reference frequencies in comparators. The output signal from the comparators are fed to an electronic unit which drives a transducer attached to oscillating mirrors. The control signal modifies the optical signal modifies the optical length of the respective measuring oscillators and stabilises the laser signal as a result against mechanical acoustic or thermal effects.

Title: Calibrating of hollow, extruded thermoplastics profiles - by applying outside reduced pressure and simultaneously inside cooling
Inventor: TITZ SIEGFRIED
IPC: B29C48/90
Filed: 1976-07-31
Abstract: Thermoplastics, hollow, extruded, profiles are calibrated by calibrating the still-plastic extrudate by applying reduced pressure from outside whilst simultaneously cooling it, indirectly from the outside and directly from the inside by introducing a cooling medium into it. In order to effect the interior, direct-cooling step, as gas-liq. mixt. is used under elevated pressure. The process minimises risk of stresses arising inside the profile, caused by uneven cooling.

Title: Ring rolling mill with conical upsetting rolls - where guide rollers for the blank are fitted on upsetting stand
Inventor: VIEREGGE FRIEDHELM ING GRAD
IPC: B21H1/06
Filed: 1976-07-31
Abstract: Ring rolling mill, for working pierced ring blanks, using one pair of rolls which work radially on the b ore and the outer dia. of the blank, while a pair of conical rolls work on the top and the bottom ends of the blanks, rolls, are mounted on a mobile upsetting stand. During rolling, the geometric tips of rolls, lie on a plane which also includes the axis of the ring blank and the axes of rotation of two centering rollers, which run on the outer dia. of the ring blank. The two rollers are mounted on slides which are synchronised with the upsetting stand so they move at the same speed as the latter. The slides on which rollers are mounted are pref. located on the upsetting stand and move at 90 degrees to the direction taken by the stand. The position of rollers is automatically adjusted during ring rolling so the rollers cannot cause deformation of the finished blank.

Title: Controlled foaming phenol! resin for building components - by phasing the location of foam formation in the mould
Inventor: IVANFI PAUL ING GRAD
IPC: E04C2/20
Filed: 1976-08-16
Abstract: Foamed flat sheet building components are produced from a reaction mixt., from phenolic resins in particular without any usual foaming agent. The resin mix is brought to the temp. of a dosing mixer and injected into the mould contg. fillers, or fibres. More material is concd. first at the part where foaming is to start, and a specific smaller quantity is subsequently injected, so producing a thermal barrier effect from the first quantity and a vertically rising foam fron until the vent is reached. This effect is also produced by heating the initial quantity while it is in the injection needle and/or feed tube or the mould wall where filling starts, or by exotherm. Controlled foaming with very short foaming distance, producing homogeneous articles without voids, suitable for very thin components giving "texture tailoring" effect.

Title: Electrical machine ribbed tube gas cooler - has tubes cooling gas with air flowing in bores
Inventor: GARZMANN TRAUGOTT DIPL ING
IPC: F28F9/22
Filed: 1977-04-06
Abstract: The gas and air coller is for electrical machines with recirculating cooling system. The cooling ribs are arranged so that no dirt can collect there and obstruct the cooling flow. The cooler has small volume and high surface area. The cooling tubes with external cooling ribs are exposed to relatively low flow velocity cooling gas. The machine heat losses are transferred to the cooling gas and the cooling air with higher flow velocity removes this heat from the smooth or longitudinally ribbed inner walls of the tubes. The external ribs, formed pref. by rolling, have relatively small depth and pitch in relation to the tube dia. The ribbed tubes are arranged in the electrical machine stacked plate as clusters. The cooling gas emerging from the stator lamellae flows over the tube outside surfaces and the gas is returned into the machine.

Title: Repeat connection long life wiring terminal - uses non-cutting edge for making scraping movement along length of conductor during positioning of contact member
Inventor: OLSEN AXEL
IPC: H01R4/24
Filed: 1977-11-23
Abstract: A wiring terminal is used for making a repetitive electrically conductive connection between an insulated line (conductor) and a conductive contact member. It comprises a housing having an orifice for insertion of an electrically conductive line (wire) of circular cross-section and an inner cavity, housing an electrically conductive contact member. In order to avoid using a cutting-edge for the wiring terminal and to keep the wear and tear of the moving parts of the terminal to a low level and thus prolong the working life of the terminal, the no-cutting edge (1) of the terminal is arranged so that during positioning of the contact member the edge makes a blunt scraping movement in the longitudinal direction of the conductor. The conductor insulation is ruptured and dislodged by the terminal edge which then plastically deforms the stripped conductor (wire) without forming any nicks or indentations.
