Patent DE-3731599-A1 (DE)
Inventor: KLUSMANN GERHARD
IPC: B60P1/34
Filed: 1987-09-19
Abstract: The invention relates to a method and device for changing troughs of dumpers with interchangeable troughs. In underground mining it is problematical to carry out a trough change because of the laterally restricted conditions since the troughs cannot be put down next to each other. According to the invention, the empty trough (2) is therefore initially raised from the transport vehicle (1) to such an extent that a full trough (3) can be pulled onto the transport vehicle in place of the empty trough. Subsequently, the empty trough is let down and put in place of the full trough. While the full trough is transported away, the empty trough left at the site can be loaded so that a quasi-continuous transport is obtained. <IMAGE>
Patent DE-3734588-A1 (DE)
Title: Recording photometer of high adaptability
Inventor: SCHMIDT WERNER DR RER NAT
IPC: G01N21/47
Filed: 1987-10-13
Abstract: The invention relates to a single-beam spectrophotometer, of which the central component is a novel monochromator (15), in which the measurement beam coming from an illumination optical unit (1-5) is dispersed by a fixed diffraction grating (8) and the stray light of first order (f) is directed away via the exit slit by means of a computer-controlled optical element (10) with reference to the wavelength in the millisecond range. The grating may be selectively replaced by a fixed prism with a specified beam path (secondary image, Figure 1). The vertical beam path through the cuvette (13) is characteristic. Conventional recording photometers are typically double-beam devices, which implies a slow wavelength progression in the minute range and the measurement only of clear, non-scattering samples with a typical optical density less than A2. The photometer described here no longer suffers these serious limitations. A particularly high light intensity with low stray light component is achieved by the deliberate use of cylindrical optics for linear focusing of the light source onto the input slit (7) and the point-shaped focusing of the exit slit (11) onto a special cuvette (13), as well as by a comparatively small number of light-deflecting elements (about 1/3 of the usual number). In conjunction with a small separation between sample (13) and detector (14), this arrangement is distinguished ... Original abstract incomplete. <IMAGE>

Title: Detecting device for the position of conveyed material, in particular a material web, moving along a conveyor section
Inventor: CASTAGNA WOLFGANG DIPL ING
IPC: B65H23/022
Filed: 1987-11-24
Abstract: The invention relates to a detecting device for the position of conveyed material, in particular a material web, moving along a conveyor section by means of optoelectronic detecting elements 9, 10. Using conventional detecting devices, it is possible to measure only the position of one or both edges, as well as to measure the change in position via an analog evaluation of the structurally determined centre deviation of the right-hand and left-hand sums of the incidence of light. In order, on the one hand, to be able to detect and acquire metrologically the position of a planar body and of its projectable contours in the plane along a conveyor section 2, the invention provides that optoelectronic light-transmitting and light-receiving elements 9, 10 are arranged in tight sequence in a detecting plane on the opposite sides of supports 5, 6 extending above and below the conveyor section 2 and at right angle thereto, that each light-receiving element 10 is assigned an address, and that an evaluation device 21 for determining the light-emitting elements 10 covered and/or exposed by the conveyed material 3 is connected to the light-receiving element 10. <IMAGE>

Title: Device for the automatic length adjustment of a Bowden cable
Inventor: JACOB WILLI
IPC: F16C1/22
Filed: 1988-02-18
Abstract: A description is given of a device for the automatic length adjustment of the tube of a Bowden cable, this device being suitable particularly for Bowden cables by means of which large forces are transmitted. The tube of the Bowden cable ends in a sleeve with a stepped outside diameter which can be inserted, counter to the force of a compression spring, into an end fitting fixed to the frame. The housing of the end fitting contains a set of distance washers which rest under spring force on the large diameter of the sleeve and, when the sleeve is displaced out of the end fitting, fall successively onto the small diameter of a sleeve. The washers which have fallen onto the small diameter extend the tube by their respective thickness and form the abutment between the sleeve collar and the inner wall of the end-fitting housing for the force exerted on the Bowden cable. In a special embodiment, the device is provided with mechanical means accessible from outside the housing of the end fitting, by the actuation of which means the distance washers which have fallen onto the smaller diameter can be returned to their initial position.

Title: Shearer loader with two hydraulic winches
Inventor: SCHROTH WOLFGANG
IPC: E21C29/10
Filed: 1988-05-27
Abstract: Leakage losses, different flow resistances as well as differences in the volumetric rates, caused by production tolerances, of two fluid pumps prevent the exact synchronous running of the fluid motors operated by them. The fluid motors each act via a reduction gear unit on a drive gear, which engages in a toothed rack and produces the travelling movement of the shearer loader. As a result of the constrained synchronism of both drive gears, the drive power outputs applied by both winches deviate from one another. The novel shearer loader is to be equipped with two largely uniformly loaded winches. It is proposed to provide devices (19, 19', 26) detecting the delivery-rate setting of both fluid pumps (13) or their volumetric flows. Connected downstream of these devices (19, 19', 26) is a common comparator (20) which has an output connected to the command transmitter (17) of both fluid pumps (13) and an output connected to the actuator (18') of the fluid pump (13) of the follow-on winch (9). The output signal of the comparator (20), produced by differences in the pump setting but also in the delivery rates, leads at the follow-up winch (9) to a correction to the pump setting and brings the speeds of both fluid motors (14) and thus also the drive power outputs of both winches (6, 9) into line. <IMAGE>
