Patent DE-3727464-A1 (DE)
Title: Process and system for the production of fuel briquettes
Inventor: LASK GERT-WILHELM DIPL CHEM DR
IPC: C10L5/04
Filed: 1987-08-18
Abstract: Process for the production of fuel briquettes, in particular for generating heat for heating purposes, coke of sand fineness, if appropriate a further non-caking fine-grained carbon source and a bituminous binder being mixed and the mixture being formed into preforms. The fuel briguettes are produced from the preforms by subjecting the latter to a heat treatment. Preforms free of molten, caking carbon are used, the specific density of which is, as a result of the adjustment of the mixing ratio and compaction, greater than the bulk density of coke of sand fineness. For the purpose of heat treatment, the preforms are introduced into a heated rotary tubular kiln which, in its lower part, is filled with coke of sand fineness to such an extent that the heat treatment takes place in a coke immersion bed. <IMAGE>

Title: Wall structure by the skeleton construction method, and process for producing a wall structure by the skeleton construction method
Inventor: LOHSE HANS DIPL ING
IPC: E04B1/26
Filed: 1987-10-17
Abstract: Known wall structures by the skeleton construction method comprise planar skeleton load-bearing members and wall panelling arranged in the interspaces. Since use is also usually made of materials with different structural properties, crack formations, as a result of loading and expansion and shrinkage processes, occur at the connections between the wall panelling and the skeleton load-bearing members. Driving rain and draughts can then penetrate at these locations and, moreover, cold bridges occur there. The invention remedies this in that the skeleton load-bearing members exhibit, on the sides bordering the wall panelling, a fold which engages over the borders of the wall panelling. Consequently, crack formation is prevented, even in the case of mutual displacement between the materials, and the penetration of moisture and draughts is eliminated. Moreover, cold bridges are avoided.

Title: Gear mechanism with a vibration-damping device
Inventor: PREMISKI CLAUDIA
IPC: F16H57/00
Filed: 1987-10-29
Abstract: In order to damp the low-speed vibrations in a gear mechanism caused by the crankshaft of the engine and made possible by the backlash, a vibration-damping device is arranged between the rotating gearwheel (1) and the fixed casing (2). Under the action of the centrifugal force, the axial extent of this device decreases as the rotational speed increases because centrifugal elements (4, 5), which are arranged on a wedge-shaped surface (3) thicker radially towards the inside and are pressed radially inwards by a spring (6), can be moved radially outwards as the rotational speed increases. <IMAGE>

Title: A method for the temperature control of a coordinate measuring device (CMD) or at least essential CMD components
Inventor: HAMMERSCHMIDT ULF DIPL PHYS
IPC: G12B7/00
Filed: 1988-04-19
Abstract: To avoid thermally conditioned measuring errors of a coordinate measuring device (CMD), its components are constructed as hollow bodies, through which a liquid from a temperature-controlled liquid bath (e.g. T = 20@C) is pumped on the counter-current principle. The flow velocity of the liquid necessary for the temperature control of the individual components is determined by an electronic controller, which determines the thermal balances of the individual components from a suitable number of surface temperatures on the CMD.

Title: Headlamp (headlight), which can be dipped, for motor vehicles
Inventor: PEITZ WOLFGANG
IPC: F21V5/00
Filed: 1988-07-20
Abstract: The headlamp, which can be dipped, has a light-collecting reflector and a lens (glass) arranged in front of the reflector in the direction of the leaving light. On the inside of the lens, cylindrical lenses are arranged in a plurality of lines one beside the other. The cylindrical lenses run vertically and are placed in each case on one prism. The prism angle amounts to approximately 2/3 of the inclination angle (tilt angle) of the lens with respect to the vertical. In this case, the reflector is inclined by half of a prism angle in the direction in which the prisms taper off. The result is an exact pattern of the light/dark boundary, that is to say the light/dark boundary shows no bending.
Patent DE-3825869-A1 (DE)
Inventor: SCHMITT WALTER ING GRAD
IPC: G01D18/00
Filed: 1988-07-29
Abstract: In such a position measuring device for measuring the relative position of two objects, the graduation (T) of a scale (TT), connected to one of the objects, is scanned by a scanning device (A) connected to the other object. The scanning device (A) exhibits an illumination unit (B) to generate two periodic scanning signals (S1, S2), which are passed in the one case to an evaluation device (W) to form measurement values for the relative position of the two objects and in the other case to an error warning device (F) to generate an error signal (FS) in the case of erroneous signal parameters of the periodic scanning signals (S1, S2). In order to check the amplitude magnitudes of the two periodic scanning signals (S1, S2), the normal supply voltage (V) for the scanning device (A) is dropped to a reduced supply voltage (Va) for a specified test time (T), so that the brightness level of the illumination unit (B) is reduced and thereby the amplitude magnitudes of the two periodic scanning signals (S1, S2) are reduced. If the error warning device (F) emits an error signal (FS) during this test time (T), then this is considered to be an advance warning that the brightness of the illumination unit (B) will soon no longer be adequate for a perfect measurement. <IMAGE>

Abstract: The invention relates to a penetration alarm system for boundaries of an area to be protected which are liable to manipulation or to destruction, having a detector arrangement, an evaluation circuit connected thereto and a triggering circuit which is controlled by it and coupled to an alarm device. To obtain, with relatively cheap sensors, a monitoring circuit which is sensitive to a sufficient degree, does not tend to trigger false alarms and is difficult to manipulate, the detector arrangement contains pieces of length of a thin resistance wire of comparatively low tensile strength, which is fitted to a carrier which is fitted to or in the endangered boundaries. Opposite these sections a resistance wire of high longitudinal expansion is arranged.

Title: Device for heating passenger compartments in an electrically driven rail vehicle
Inventor: ZENGERLE MANFRED DIPL ING
IPC: B60L1/02
Filed: 1988-09-12
Abstract: In electrically driven rail vehicles with power converters it is customary to charge the capacitive components of the power converter circuits with limited current before the start of operation by means of a charging resistor (RLH) and a charging protector (SL). It is proposed to use this charging resistor (RLH) in addition for heating the passenger compartment. For this purpose, the terminal of the charging resistor which is not connected to mains voltage can be connected via a heater protector (SH) to the earth potential of the supplying voltage source. When required, the charging resistor can be used for heating purposes in the state of rest, in normal operation, i.e. for driving, and for braking or recuperation operation of the vehicle. <IMAGE>
