Patent DE-3334133-A1 (DE)
Title: Pole reversal on three-phase motors, using capacitors
Inventor: LEHMANN BERND
IPC: H02K17/14
Filed: 1983-09-19
Abstract: Pole reversal on three-phase motors, using capacitors for pole numbers up to 5, in the ratio 1:2:3:4:5. The method is an expansion of the known Dahlander reversal (2:4) by the stages 1, 3 and 5. Three capacitors are integrated into the circuit of a normal three-phase two-layer winding, for this purpose. By means of the capacitors, balanced three-phase operation is also made possible for stages 1, 3 and 5, but only for one operating point. Advantageous applications include, for example:     2/6/10-, 2/10-, 4/6- or 6/8 pole motors, high-voltage motors or reversible-pole single-phase motors using the Steinmatz circuit.   For some ratios of pole numbers, such as 4/6- or 6/8 pole motors, one capacitor of triple capacitance, for example, is adequate, or a single-layer winding can also be used, and it is furthermore possible to select a circuit in which the capacitors in stages 2 or 4 are automatically used for compensation of the reactive current.

IPC: G01G19/03
Filed: 1983-10-06
Abstract: The present invention relates to a weighing device for weighing heavy loads, especially road vehicles, consisting of a rigid housing, a dynamometer arrangement equipped with strain gauges, and an evaluation circuit determining the weight of the load to be weighed. So that a weighing device of this type can be used as an easily transportable movable device, whilst at the same time achieving a high weighing accuracy, it is proposed, within the scope of the present invention, that the dynamometer arrangement be arranged between the rigid housing (3) and a fixed bearing surface (17) of flat design, whilst the top side of the rigid housing (3) serves as a measuring platform. <IMAGE>

Title: Proportional counter for detecting surface contamination
Inventor: KELLER MANFRED DR
IPC: H01J47/00
Filed: 1983-11-05
Abstract: Proportional counters for detecting radioactive surface contamination, whose housings are largely formed by a frame over which especially window foil is clamped as a thin-walled radiation inlet window, have a polygonal grid, especially a hexagonal grid whose webs do not lie in the main scanning direction, as a perforated-grid cage which is provided at a distance from the thin-walled frame and ensures a specific minimum distance of the frame from the scanning surface. Such hexagonal-grid cages are particularly expedient for cylindrical measurement probes for checking pipelines.

Title: Roller shutter safety device
Inventor: GRUTESEN HANS-JOSEF
IPC: E06B9/80
Filed: 1984-12-19
Abstract: Arranged on a roller shutter web on the left and on the right are safety device housings which can be adapted accurately to the profile of the web and which in each case contain a vertically and a horizontally movable slide part. The vertical part engages with a spring arranged at a given angle in a corresponding groove of the horizontal part. Only by turning the roller shutter rolling-up roller is the roller shutter locked on lowering as a shorter pull band is fastened on the vertical slide part, as a result of which this part only goes downwards when the roller shutter web is put on, drawn by a steel spring. Release can also take place by the weight of an additional web. In this case, the horizontal slide part is pressed outwards and its bolt slides into a bore of the roller shutter guide rail. The vertical part slides behind the horizontal part and blocks it. On the other hand, only by turning the roller shutter rolling-up roller is unlocking carried out. Additionally, a contact, actuated by the safety bolt, for an alarm installation can also be arranged.

Title: Piston, in particular that of an internal combustion engine
Inventor: DESCHLER GERHARD DIPL ING
IPC: F16J1/16
Filed: 1984-12-21
Abstract: The invention relates to a piston, in particular that of an internal combustion engine, with a gudgeon pin and a connecting rod engaging at that point, the piston or the connecting rod being provided with holes in which the gudgeon pin is mounted in a floating manner. While retaining the same weight ratios, the invention proposes a gudgeon pin for such a piston which, without loss of functioning capacity, bears a high proportion of the load and is inexpensive to manufacture. According to the invention, this is achieved by virtue of the fact that the gudgeon pin is designed as a solid pin and that the length/diameter ratio l/d of the pin is between 1.5 and 2.0.

Title: Sound absorption construction for ballast-less railway superstructures
IPC: E01B2/00
Filed: 1985-08-02
Abstract: With sound absorption constructions for ballast-less track superstructures, which consist mainly of reverberant concrete plates, it is to be brought about that the sound levels in the region of such superstructures do not lie higher than in the case of conventional ballast superstructures. Investigations with rock wool mats, which were fastened expensively with wire netting, and with poured mineral grains, which were bonded with plastic, revealed that with these constructions only limited reductions, and in particular only in quite definite frequency ranges, can be achieved. With the structure according to the invention made of underlying mineral or rock wool plate and a layer of mineral grains arranged thereon which at the same time serves as ballast for the mineral material plates, a sound absorption is achieved, which is uniformly good over the entire frequency range, the mineral material plates covering the high and the mineral grains the low frequencies.
