Title: Illumination for closed elongate rooms
Inventor: BALLA PETER ALEXANDER DIPL ING
IPC: F21V3/00
Filed: 1987-09-04
Abstract: The illumination has a centrally arranged light source (2) which is covered at the top by a roof reflector (3). A cover (8) consisting of clear glass is present below the light source (2) and is at least partially provided with prismatic grooves (11). The light which comes from a vertical direction is laterally deflected with respect to the vertical central plane, while the light which falls obliquely onto the prismatic grooves is deflected as secondary radiation in a manner inclined with respect to the horizontal plane. An interspace with low illumination remains between the primary radiation and secondary radiation. As a result of the direct radiation directed downwards, the light is prevented from dazzling and an even distribution of light towards the right and towards the left is achieved. <IMAGE>

Abstract: The invention relates to a locking device, of which the locking shaft (5) cooperating with the bolt (32) is blocked by a blocking plate (2) mounted so as to be displaceable perpendicularly to the locking shaft (5). In the blocked state, the blocking plate (2) engages with its blocking extension (3) into a recess (4) of the locking shaft (5) under the effect of the spring (34). With its lower edge, the blocking plate (2) butts against detent elements (7) or against special attachments arranged adjustably on them and is thus held in the blocking position. The detent elements (7) are provided with clearances or perforations which are brought into correspondance with the lower edge of the blocking plate (2) as a result of the displacement of the detent elements (7) by respective specific amounts corresponding to the secret code, so that the blocking plate (2) can shift downwards and releases the locking shaft (5). The correctly positioned displacement of the detent elements (7) takes place by means of a locking card having projections protruding with correspondingly correct length. The secret code can easily be set and changed by the authorised person. The key designed as a flat locking card can easily be stored and, for example, carried in the briefcase or the like. <IMAGE>

Patent DE-3827618-A1 (DE)
Title: Sensor-controlled tracking device
Inventor: PERTL PETER
IPC: G01C15/00
Filed: 1988-08-14
Abstract: A sensor-controlled tracking device works with a laser sensor positioned on a working device, the laser sensor responding to a reference plane predetermined by means of a laser generator. In the case of a deviation of the laser sensor from the reference plane, the actuator (7), which can be adjusted to a height differing from that of the working device, and thus the laser sensor are displaced in the sense of a tracking on the reference plane. The violent shocks which often occur in ground work lead to a considerable vibration and to a frequent deviation of the laser sensor from the reference plane. A sensor-controlled tracking device which is improved with respect to this is mounted on a construction site vehicle itself and is fitted with a height adjustment device (17) for tracking the laser sensor onto the reference plane (R). Mechanically decoupled therefrom, the at least one working device (1) is tracked in accordance with the adjusting movement of the height adjusting device (17). The tracking device is particularly suitable for construction vehicles. <IMAGE>

Title: Method for monitoring the insulating gas of pressurised-gas-insulated switchgears and control device for implementing this method
Inventor: STEGMUELLER KARL DIPL ING
IPC: H01H33/56
Filed: 1988-08-18
Abstract: The invention relates to an improved method for monitoring the insulating gas of pressurised-gas-insulated switchgears. The state variables pressure and temperature are detected in each compartment (1) by means of a temperature-compensated pressure sensor (2), while in a microprocessor (10) belonging to a central processing unit (3), the signals input for the gas density ( sigma G) are converted into values of the dielectric strength (U) with the aid of suitable software. When the voltage drops below a certain voltage level (Up) dependent on the nominal voltage, interruption of the damaged system part or other measures are implemented by the microprocessor (10). The novel method can also advantageously be connected to an electronic network control system, as a result of which the availability of the power supply is increased. <IMAGE>

Inventor: BAEUML-KLOTT BEATRIX
IPC: A62D101/22
Filed: 1988-08-24
Abstract: In the pyrolytic utilisation of starting material which is contaminated by halogenated hydrocarbons, toxic pollutants can be formed. The pyrolysis is therefore carried out in the presence of basic additives which bind the pollutants and the heavy oil obtained is recirculated to the pyrolysis reactor. This allows starting materials contaminated by halogenated hydrocarbons to be utilised in a very simple, economical and environmentally friendly manner.
Patent DE-3833553-A1 (DE)
Title: Fixed-calliper spot-type disk brake with an asymmetrically split housing
Inventor: THIEL RUDOLF
IPC: F16D55/226
Filed: 1988-10-01
Abstract: The invention relates to a spot-type disk brake with a brake housing, in which the housing is split in a plane parallel to the brake disk and the first of the two housing parts has flanges to allow it to be fastened to the vehicle to be braked. With fixed-calliper disk brakes, it is known to split the housing radially in the centre plane of the brake disk. It is furthermore known to split a fixed-calliper brake housing asymmetrically, the cutting plane being displaced away from the brake disk towards the outer braking gradient. A construction of this kind does however presuppose that there is furthermore sufficient housing material surrounding the interfaces to allow the housing parts to be screwed together and allow the necessary forces to be exerted. It is the object of the invention to be able to make available a high braking power with a brake which takes up little installation space. The invention consists in principle in executing the cutting line (F-D) on the flange side of the housing (3, 4). This ensures that the thickness of material required for the housing bridge can be kept very small. To further increase strength, the invention recommends that the cutting plane be located in the plane of the brake-disk end of the cylinder (10, 11). <IMAGE>

Title: Plug-in connection which is secured with respect to axial displacement and is intended for socket pipes
Inventor: MUECHER HORST ADOLF
IPC: F16L21/03
Filed: 1989-03-08
Abstract: For the production of a plug-in connection which is secured with respect to axial displacement and is intended for socket pipes, use is made of a sealing ring (1) which is manufactured from an elastomeric extruded profile and in whose hollow channel (4), provided with an opening (5) continuing to the outside, there is arranged a reinforcement ring (3) which secures against axial displacement. In order to prevent the reinforcement ring (3) from coming out of the hollow channel (4) during transportation, preliminary mounting or mounting of the sealing ring (1), the opening (5) of the hollow channel (4) either extends only over a sub-region (6) of the ring circumference and/or said opening (5) is closed off by vulcanising, adhesive bonding, clamping or the like or by a continuous material portion of the sealing ring (1), e.g. by a lug (9). The plug-in connection which is secured with respect to axial displacement is preferably used for sealing concrete socket pipes in the case of which the on-site installation of loose, axially non-secured sealing rings, in particular rolling rings, in order to avoid incorrect mounting, is becoming less and less common or, as a result of special quality specifications, is no longer permissible. <IMAGE>
