Title: Adsorption-type heat storage system
Inventor: HOEPPLER ROBERT DR
IPC: F28D20/00
Filed: 1993-04-02
Abstract: Provided inside a zeolite adsorber is a heat exchanger which is a component of a heating circuit which inter alia also leads via a useful heat exchanger in which the useful heat can be employed, for example, to heat a vehicle interior. The heating circuit has a bypass which circumvents the adsorber and in which a timing valve is provided. By means of the timing operation of this timing valve, a recirculating pump can start up the heating circuit even through the adsorber, although in the preceding desorption process the heating medium has changed its phase state in the adsorber heat exchanger, with the result that a steam bubble was produced there. The heating medium can be fed to the useful heat exchanger by mixing superheated steam from the adsorber and liquid via the bypass immediately downstream of the adsorber with the aid of conventional hot water hoses. Also specified are advantageous design details of an adsorber/evaporation chamber unit.

Title: Roller for the wet treatment of web-like liquid-permeable textile material
Inventor: GUILLOT FRANZ E
IPC: D06B23/02
Filed: 1993-06-04
Abstract: The roller according to the invention stores the treatment liquid, penetrating the treatment material, in liquid chambers on its circumference and, during the rotation of the roller, transfers it again to the treatment material in the direction of run. The multiple penetration of the treatment material with treatment liquid which thereby occurs brings about a rapid and uniform wetting of the treatment material with a high liquor exchange within the treatment material. The design according to the invention of the liquid chambers induces the local concentration of the liquid circulation over the width of the treatment material and therefore an economical and environmentally friendly mode of treatment.

Title: Aplanatic and anastigmatic mirror system with a plane image field
Inventor: GALLERT FRANK
IPC: G02B17/06
Filed: 1993-07-02
Abstract: The subject-matter of the invention is a high-performance (high-aperture) 3-mirror system for astronomy. In this invention, an afocal 2-mirror system which comprises a collecting main mirror and a smaller diverging mirror produces from incident bundles of parallel light restricted bundles of likewise parallel light. The latter finally impinge on a collecting mirror which is likewise smaller than the main mirror, after which the light is concentrated onto a detector. For each selected distance of the collecting mirror from the diverging mirror, an unambiguous number triple of three Schwarzschild constants, which describe the surface geometry of the 3 mirrors, can, then, be specified in such a manner that the mirror system is aplanatic and anastigmatic. Finally, the radius of curvature of the collecting mirror can be determined for a selected afocal partial system such that the Petzval sum also becomes zero, with the result that, overall, an aplanatic and anastigmatic mirror system with a plane image field is produced which provides excellent diffraction-limited correction on the transferrable field of view.

Title: Supply circuit for DC motors without commutators
Inventor: HEYDT THOMAS VON DER
IPC: H02P6/10
Filed: 1993-07-14
Abstract: A supply circuit for two-pulse DC motors, in particular two-winding DC motors, without commutators. The circuit modulates, for example, an externally supplied PWM signal with an essentially constant duty ratio onto two separate channels, in accordance with a commutation signal. The amplitude of the individual PWM pulses is increased or reduced in steps or virtually continuously, via circuits which act linearly, at the start of or towards the end, respectively, of a pulse train which consists of a plurality of such individual pulses. The waveform, with respect to time, of the current through an individual motor coil in consequence has a shape which rises and falls, respectively, in the form of a ramp and, in consequence, a high motor efficiency is achieved. The circuit has current limiting properties, as a result of which smooth running of the motor is achieved.

Title: Method of bonding and sealing shaped metal components
Inventor: HEIN LOTHAR DIPL ING
IPC: C08G18/10
Filed: 1993-07-21
Abstract: In order, when laying and joining metallic shaped components, for example gutters, to enable welding or soldering to be avoided and to permit unhindered thermo expansion, it is proposed adhesively to bond the shaped components (3, 4), which have been pretreated by degreasing and with primers, with the aid of shaped pieces such as a sleeve, the adhesive used being a polyurethane adhesive of defined minimum thickness. The shaped components (3, 4) may have an expansion joint (5) between their heads; however, it is also possible to insert them inside one another with the possibility for longitudinal mobility. In the case of direct adhesive bonding of the end regions (1, 2), where it is not possible to conform to a minimum thickness of the line of adhesive, it is necessary in addition to mount longitudinal expansion compensators. <IMAGE>

Title: Wiper blade with a multi-section supporting frame
Inventor: CRAMER HANS-DIETER ING GRAD
IPC: B60S1/38
Filed: 1993-07-30
Abstract: The proposal is for a wiper blade which serves for cleaning windows/lens glasses on motor vehicles. The wiper blade comprises a multi-section supporting frame to which a driven wiper arm is coupled and which grasps, by means of pairs of claws arranged one behind another on frame parts, the spine of an elongate wiper strip which is made of elastic material and is positioned, with a wiper lip, on the window/lens glass to be wiped. The claws of each pair of claws reach into opposite longitudinal grooves arranged in the longitudinal sides of the spine and in the spine there is arranged a longitudinal recess for receiving an elastic reinforcing rail, the length of which approximately corresponds to the length of the spine protruding with its ends out of the outer pairs of claws, and the wiper blade has retaining means which secure, in the longitudinal direction, the reinforcing rail in the spine and the wiper strip in the pairs of claws. A particularly easy-to-assemble wiper blade results if the longitudinal recess in the wiper-strip spine is formed as a through-channel which is closed all around and the cross-section of which matches the cross-section of the reinforcing rail, if the retaining means are designed as a structural element which can be attached onto one end of the spine, reaches, with at least one latching shoulder, into the through-channel and interacts there with a counterlatching shoulder of the reinforcing rail, and if, furthermore, the structural element with the ...
