Title: Metal louvre for ventilation
Inventor: BLANK MAX
IPC: E06B7/086
Filed: 1987-04-22
Abstract: There exists a louvre for ventilation which is produced from metal and has slats (8) which are rotatably mounted in a frame (1) and are in each case articulated, at one end, on a common sliding strip (11) via a lug (9) by means of riveting (12), to which sliding strip an eccentric connection strap (13) is firmly connected (12) on the outside of the frame (1), the frame (1) consisting of frame parts (2, 3) which are firmly connected (6) to one another. In this arrangement, it is desirable if the production of the various connections is simplified. This is achieved in that the connection of the slats (8) - lugs (9) to the sliding strip (11), the eccentric connection strap (13) to the sliding strip (11) and the frame parts (2, 3) to one another is in each case formed by a drawn-through rivet eye (6, 12). The drawn-through rivet eye enables, on the one hand, articulated connections and, on the other hand, fixed connections which are sufficiently stable and durable. <IMAGE>

Patent DE-3717791-A1 (DE)
Inventor: LICINIO UGO
IPC: G01P3/50
Filed: 1987-05-26
Abstract: The invention relates to an optoelectronic system for determining the direction and the speed V of a moving vehicle by means of the internal emission of laser beams z, z1. In order to take into account the relative contraction corresponding to the ratio V/c, the time values are measured simultaneously by the two processes described, that is to say by means of two instruments M having exactly equal dimensions, with two light beams moving in mutually opposite directions and with identical angles of reflection between the parallel mirrors W, W1; the continuous reference element is a sequence of short laser pulses generated inside the instrument and, in measuring the real time, the Lorentz-Fitzgerald contraction is taken into consideration so that the scale of the measurement values is very wide, also for very high speeds. Application to terrestrial and space vehicles. <IMAGE>

Title: Brake pressure control device
Inventor: BEHLER HELMUT
IPC: B60T8/48
Filed: 1987-07-13
Abstract: The invention relates to a brake pressure control device for the traction control of a hydraulic brake system with antilock device for motor vehicles. It proceeds from an antilock device of conventional type, which comprises a tandem master cylinder (13) with hydraulic brake booster (41), and a modulator (14) for modulation of the wheel cylinder pressures. The modulator comprises inlet and outlet valves for controlling the pressure in the wheel cylinders of the brakes in antilock control mode and in traction control mode. For accomplishing the traction control mode a pressure medium line (39) is provided, which connects the pressure medium supply system (4) to at least one working chamber (25, 26) in the master cylinder. This pressure medium line (traction control line) is connected to the circuit only in traction control mode. For this purpose, a separate valve (traction control valve) (44) in the form of a two/two-way directional valve is provided, which in traction control mode is switched to allow passage. In order to safeguard the traction control line against a fall in pressure in other parts of the brake pressure control device and in the reservoir (47), the main valve (5) belonging to the antilock device is used. By means of this invention, the cost of valves in a combined antilock and traction control device is reduced.   <IMAGE>

Title: Device for inductively heating rods or the like
Inventor: JUERGENS HEINZ DIPL ING
IPC: H05B6/02
Filed: 1987-07-25
Abstract: Inductive heating of rods for subsequent treatment (rolling mill, forge), the inductive heating being subdivided into a zone of heating up to the subsequent treatment temperature (rolling temperature, forging temperature) and a second zone for maintaining the subsequent treatment temperature. In the case of long workpieces, the coil interior cools down too much, since the rods are quickly moved out of the heat-maintaining zone, while it takes a certain period of time until the space is again filled by the rods moving up. A drop in the temperature of a workpiece after it has been transported out of the heat-maintaining zone in the coil interior can be avoided by providing the coils in the heat-maintaining zone with intermediate tubes of electrically conductive material whose inner dimensions are larger than the outer dimensions of the rods or the like. The wall thickness of the intermediate tube and the feed frequency of the induction coil are selected such that the penetration depth of the induction is equal to or greater than the wall thickness of the intermediate tube. Inductive heating of long rods. <IMAGE>

Title: Process for the thermal purification of contaminated materials
Inventor: HARTMANN HELMUT DR
IPC: F23G5/02
Filed: 1987-11-04
Abstract: A process for the thermal purification of contaminated materials, preferably bulk solids rich in ash is described. It comprises driving off, in a first evaporation step, low-boiling point contaminants and water, and subjecting the gases/vapours driven off in this first evaporation step to secondary combustion in a combustion machine, in order to destroy the contaminants. The higher-boiling point contaminants are driven off in a second evaporation step by means of the contaminants being subjected, for the purpose of evaporation, to appropriate individual temperature profiles/final temperatures and residence times. The gases driven off in this second evaporation step then undergo secondary combustion in a directly fired thermal secondary combustion plant. One of the advantages of this process is that the amounts of material undergoing the second evaporation step are smaller than in known processes, thus requiring smaller investments to set up an installation suitable for carrying out the process. Furthermore, residual toxic pollution is reduced. Advantageous refinements of the process are described in which, in particular, energy utilisation is optimised by means of combined heat and power generation.
Patent DE-3738441-A1 (DE)
Title: Device for the automatic length adjustment of a Bowden cable
Inventor: JAKOB WILLI
IPC: F16C1/22
Filed: 1987-11-12
Abstract: A description is given of a device for the automatic length adjustment of the tube of a Bowden cable. The device is distinguished by the fact that the tube end, which is provided with an external thread, is passed through an end fitting which is fixed to the frame and on which it is held by an internally threaded sleeve which surrounds the tube end, is divided axially into two and is held together by an annular tension spring. The parts of the sleeve are provided on the outside with grips which, when compressed in the direction of the tube axis allow the internal thread of the parts of the sleeve to be lifted out of the external thread of the tube end. With the internal thread lifted out, a compression spring inserted between the end fitting or the sleeve and a stop fixed to the tube stretches the tube to the required length. A corresponding design of the thread cross-sections allows the compression spring to automatically readjust the length of the tube by pulling the tube end out of the end fitting, during which process the threads slide over one another.

Title: Vibration-compensated electrodynamic sound transducer drive
Inventor: RIEDER JOACHIM
IPC: H04R1/20
Filed: 1988-01-14
Abstract: The most frequently used sound transducer operates in accordance with the electrodynamic principle. These sound transducers have a negative characteristic which previously has never been taken into consideration and which has already presented insoluble problems to many a developer of loudspeakers. These problems are the enclosure vibrations caused by these sound transducers. These vibrations are caused in fact not only by the enclosed air but, above all, directly by the sound transducer itself. According to a physical law, each force generates a counterforce of the same magnitude. If, therefore, a force acts on the diaphragm out of the mass of the drive, then the same force acts out of the drive into the loudspeaker enclosure. Only a small proportion of this force is absorbed in the mass of the drive itself. The invention indicates how this reaction can be prevented with the aid of a second drive. The higher price for such a vibration-compensated sound transducer is easily compensated for by the simpler enclosure design and the better sound.

Patent DE-3802266-A1 (DE)
Title: Press
Inventor: DOEGE ECKART PROF DR ING
IPC: B30B1/32
Filed: 1988-01-27
Abstract: In conventional presses, tilting and displacement of the press ram occur whenever the resultant of the press force (KE) fails to coincide with the pressing axis (30), leading to uneven insertion of the upper tool into the lower tool. According to the invention, such tilting movements are avoided in that the bedplate (12) and/or press ram (17) are composed of a guide plate (13, 18) and a supporting body (14, 19) which supports the guide plate from outside. The drive devices (23, 24) only engage on the supporting body (14, 19) and their forces are in inverse proportion to their distances from the position of the resultant of the pressing force (KE). A convex supporting surface (28) ensures that the centre of pressure (AP) is set in such a way that it is on the same straight line as the resultant of the pressing force (KE). As a result, tilting and displacement of the tools (16, 21) with respect to one another are avoided. <IMAGE>

IPC: G02B21/24
Filed: 1988-02-01
Abstract: The invention relates to a focusing device, preferably for microscopes, which permits two mutually independent movements of an objective or object stage holder in the direction of the object or the objective and away from it. An actuating drive (actuator), a gear (gear reducer unit), a ball bearing, an equalising device, and a holder are provided, the gear being designed according to the invention in such a manner that a stop is firmly connected to a driving toothed wheel which is located on a shaft so as to be rotatable, and a stop pin being firmly arranged on the shaft in the region of the stop. Furthermore, a block (obstruction) for the lens turret movement and a braking device for a soft stop are provided. In addition to the focusing movement a fast lifting is implemented for the objective change while achieving a cost-effective construction. Defects on the object or the objective or the movement mechanism which occur as a result of an inadvertent collision between the objective and the object during focusing are ruled out. <IMAGE>

Title: Method for the production of a supporting body for a catalytic reactor for emission control
Inventor: HUMPOLIK BOHUMIL
IPC: F01N3/28
Filed: 1988-05-21
Abstract: Known winding methods only allow the production of supporting-body cross-sections to deviate significantly from a circular or oval shape when certain winding equipment or certain involved winding methods are used. The proposal also is to wind in spacers during the winding process, at least in partial areas of the wound strips. After their removal, these leave spaces which allow the wound bodies thus formed subsequently to be pressed in to give even irregular and complex cross-sectional shapes. Use for catalytic converters of motor-vehicle engines. <IMAGE>
