Patent DE-3111287-A1 (DE)
Title: Electrical contact plug connection
Inventor: ILLIES REINHOLD DIPL ING
IPC: H01R13/187
Filed: 1981-03-23
Abstract: In electrical contact plug connections, having a plug (ST) and socket (BS), there is a problem in making contact correctly and securing the contact in the closed state with a minimum extraction force which can be specified while at the same time providing easy handling without special locking elements. The contact plug connection solves this problem by a resiliently acting pressure device for contact elements and contact securing elements. In design, a positively locking latch is achieved between the socket and the plug with the aid of movably supported latching bodies (RK) on which the resiliently acting pressing device (AP) acts, which pressing device (AP) allows the latching body to engage in a positively locking manner when the plug connection is closed into a corresponding latching recess in the respectively opposite plug connection part (ST). The geometrical shape of the latching body and the latching recess, as well as the dimensioning of the pressing device, permit the setting of defined positively locking forces which are constant in the long term and are adequate for retention security. <IMAGE>

Title: Material testing apparatus, in particular metal-sheet testing apparatus
Inventor: LORENZ REINER
IPC: G01N3/42
Filed: 1981-05-09
Abstract: The invention relates to a hand-operated material testing apparatus, in particular a metal-sheet testing apparatus, for testing uncoated and coated thin metal sheets by pressing a spherical die into the metal-sheet specimen by means of a threaded spindle. A loaded force measuring system enables the specified clamping force to be set. The object of the invention is to design the test apparatus in such a way that the hydraulic force measuring system can be replaced as a unit, and this is made possible, according to the invention, as a consequence of an appropriate pressure pipe run and an appropriate arrangement of a pressure ring. The invention shown in figures can be applied to material testing apparatuses in which a specified force has to be set in testing thin metal sheets. <IMAGE>

Title: Electrical machine, in particular a small motor
Inventor: CORBACH RAINER DR ING
IPC: H02K23/04
Filed: 1981-05-19
Abstract: An electrical machine, in particular a small motor, is specified which has a so-called two-component magnet. For the purpose of increasing the resistance of the permanent magnets to demagnetisation when starting is assisted by oversized batteries or when the brushes are displaced against the rotating direction, the two segment sections - in contrast to the previous calculation method - are dimensioned in accordance with the criteria a-d of Claim 1. As an additional advantage, higher effective remanence and hence an increase in flux are achieved with this design. <IMAGE>

Title: Hopper for the intermediate storage of bulk material which is threatened by fire and explosion, and method for operating such a hopper
Inventor: GESSLER HANS
IPC: B65G65/46
Filed: 1981-05-23
Abstract: The invention relates to a hopper for the intermediate storage of bulk material which is threatened by fire and explosion, such as wood chips, fibrous materials or the like, having a gravity chute (9), a scanning device (19, 20, 22) which scans the stream of conveyed material for material which has ignited, and having at least one drawing-off device (12). Sources of combustion may arise as the bulk material is being processed, which are fed together with the stream of conveyed material to the hopper (1), where they may initiate detonations and/or explosions and fires which may spread beyond the drawing-off device (12) to expensive processing machinery arranged downstream. According to the invention, the drawing-off device (12) is inclined downwards at an angle to the vertical in the main conveying direction (13), so that a chip buffer is respectively positioned in front of the drawing-off aperture (15) in all operating conditions, which buffer prevents the spread of fire and/or explosions. One advantageous method for operating a hopper as shown in Figure 1 is characterised by scanning of the stream of conveyed material as it enters the hopper (1), by means of a scanning device (19, 20, 22), to check for the presence of material which has ignited and changeover of the drawing-off device (12) when the scanning device (19, 20, 22) responds from a main conveying direction (13) to an auxiliary conveying direction (14). The hopper contents which contain sources of fire and any extinguishing agents which may have been introduced, are separated without danger from the stream of material conveyed to the processing system, in such a manner as to avoid follow-on damage. <IMAGE>

Patent DE-3128847-A1 (DE)
Title: Roadway conveyor for underground mining operations and method of using the roadway conveyor
Inventor: PAURAT FRIEDRICH WILHELM
IPC: B65G15/08
Filed: 1981-07-22
Abstract: The invention relates to a roadway conveyor for underground mining operations, with a conveyor frame, at least one drawing means and a supporting means. The drawing means runs via a drive. The supporting means is run as a trough in sections of the conveying path intended for the feeding and delivery of material and as a flexible conveyor tube in the curved area. This applies to the entire conveying path except for the sections intended for the feeding or delivery of the material. The supporting means can be of heat-insulating and/or heat-reflecting design. Consequently, the mine climate can be improved by means of the roadway conveyor described, because the heat exchange of the coal to be conveyed with the environment is reduced or interrupted. It is also within the scope of the invention to use the flexible conveyor tube and/or the return strand closed to the flexible tube as an air duct. <IMAGE>
