Patent DE-4235071-A1 (DE)
Title: Synthetic aperture radar equipment based on use of rotary antennae - overcomes range ambiguity by transmission of pulses having distinguishable characteristic in repetitive sequence
Inventor: KALTSCHMIDT HORST PROF DIPL IN
IPC: G01S13/90
Filed: 1992-10-17
Abstract: The radar equipment correlates (11) a received signal with reference functions generated (13) and stored in memory (12). A quadrature demodulator (8) of the IF signal delivers outputs in phase and quadrature for digitisation (9) and buffer storage (10). The correlator is clocked (6) for each individual range interval in common with a ring counter (5) which sets the periodicity of pulse transmission in sequences with progressively increased frequency or varied pulse shape (e.g. pseudo-noise encoded signal design). ADVANTAGE - Unambiguously distinguishable response signals can be received and processed even at long ranges with aid of different characteristics of successive pulses.

Title: Distance sensor for press. converter - has immersion piston, pneumatic controller, working piston displacement detector and electronic controller
IPC: G01B7/02
Filed: 1992-10-26
Abstract: The distance sensor has a working piston (9) operating in a cylindrical housing opening and coaxially connected to an externally protruding piston rod (3). A plate piston (11) mounted with radial sealing in a cylinder to produce a rapid forward stroke and reverse stroke separates two pneumatic chambers (12,13). A transducer (31) detects the movement of the working piston to measure the rapid forward (I) and reverse (III) strokes and the working stroke (II). The transducer output is passed to an electronic controller (28)  which detects displacement errors wrt. a desired displacement, controls the pneumatic controller and/or drives a display (36). USE/ADVANTAGE  - Esp. for use in mass production applications. Enables accurate monitoring of effective working stroke.

Inventor: POEPEL WOLFGANG JUERGEN DR
IPC: B01J23/94
Filed: 1992-11-09
Abstract: Proposed is a method of producing catalysts containing iron, potassium and cerium from spent catalysts of this type used in the dehydrogenation of hydrocarbons (i.e. a regeneration method). The method calls for the spent catalyst to be ground and optionally cleaned, and the original catalytic action to be produced again by adjustment of the composition and restoring the external form, an effective quantity of potassium being added to the ground material together with a quantity of cerium such that the total amount of cerium is greater than that originally present.

Title: Device for reconstructing a hologram
Inventor: NEUNER JOERG DIPL ING
IPC: G03H1/24
Filed: 1993-03-25
Abstract: The present invention relates to a device for reconstructing a hologram, which in the collapsed state is easy to transport and can be brought into the functional position for viewing holograms, it being possible either to set it up on a level surface or to fasten it on a wall or on a tripod. A particular advantage of this device consists in the fact that holograms having flat hologram planes of varying sizes can be clamped in for viewing and illuminated by means of adjustable illumination facilities, as a result of which the specific properties of the representative (representational) holography produced by the difference in illumination direction can be utilised specifically and universally. According to Figure 4 the device consists of two mutually parallel arc rods 6 which are rigidly connected at their ends to two likewise mutually parallel cross rods 7 by means of four corner connectors 8 so that the four rods form a rectangle, there being additionally connected to each corner connector in each case one end of a guide arc 4 such that the two guide arcs describe two mutually parallel semicircles which have one arc rod each as diameter and stand perpendicularly to the cross rods 7 and face the viewer 19 with their domed side. The hologram 1 fastened on the cross supports 3 can be displaced on the guide arc into different angles with respect to the viewer. The light source 11 in low-voltage halogen technology ...

Patent DE-4327852-A1 (DE)
Title: Container for storing tennis balls
IPC: A63B39/02
Filed: 1993-08-19
Abstract: Tennis balls suitable for tennis tournaments are packed under pressure during manufacture in order that they have a predetermined pressure when they are used for the tennis match. However, the commercially conventional pressurised packaging guarantees preservation of the internal tennis ball pressure only as long as the packaging is in undamaged original condition. If the tennis balls are taken out of the pressurised packaging for a tennis match, a constant pressure loss sets in from then on which leads to rapid ageing of the tennis balls irrespective of whether the tennis balls are used for play or merely stored. This undesirable ageing of the tennis balls leads to only infrequently used tennis balls often having to be exchanged for new although they are new as far as the external quality is concerned and are unusable only as a result of the pressure loss which has occurred. The invention ensures, by means of the features indicated in the precharacterising clause of Claim 1 and in the characterising part, that the ageing of the tennis balls caused by pressure loss is prevented for a long time. <IMAGE>

Patent DE-4331553-A1 (DE)
Title: Thread-processing machine with a thread-changing device
Inventor: BUCHER GERT
IPC: D05B65/00
Filed: 1993-09-16
Abstract: In thread-processing operations, such as, for example, embroidering, it happens relatively frequently, under certain circumstances, that the thread has to be changed. To avoid threading the new desired thread, which, for example, has a different colour from the old thread, manually through the various guides of the thread-processing machine, the old thread must be clipped and tied as automatically as possible together with the new thread. It is known, for this purpose, to utilise swirling by means of compressed air in a swirl chamber to join the two threads, but the execution of this is not always reliable and the device required is relatively complicated. In order to increase the reliability and keep the outlay in terms of construction for this within limits, it is proposed, according to the invention, during the swirling in the swirl chamber, to hold the two threads virtually loosely in the longitudinal direction over at least the length of 1 cm and to retain each of the two threads directly at the swirl chamber, at most on one side of the swirl chamber, without the formation of a loose intermediate loop.

Title: Apparatus for producing corrugated pipes from thermoplastic material
Inventor: DIETRICH KARL
IPC: B29C48/32
Filed: 1993-11-15
Abstract: An apparatus for producing corrugated pipes from thermoplastic material has a moulding line which is arranged such that it adjoins an extrusion head of an extruder and comprises a guide which is arranged in a frame and on which mould halves, in closed in a run-in in pairs to form annular moulds, are advanced following closely one after the other and are provided on their underside with toothed racks. Arranged in the initial region of the moulding line are drive pinions, which mesh with the toothed racks of the pushed-together mould halves. In a run-out following the moulding line, the mould halves are separated from each other and transferred onto return lines, which are separate from each other and on which they are returned to the run-in by conveying means. To be able to return the mould halves reliably and quickly to the run-in via the return lines, the conveying means comprise driven pinions which come into engagement one after the other with the toothed racks of the mould halves. The transverse conveyance of the mould halves between the run-out and run-in takes place by means of pinions driven in a transversely movable manner.

Title: Adjustment of camshaft relative to crankshaft
Inventor: SCHULTE WOLFGANG
IPC: F01L1/34
Filed: 1993-11-29
Abstract: A device to rotate a camshaft with respect to a crankshaft in a car has a correcting element controlled by an electrical signal, a camshaft sensor system which evaluates the instantaneous camshaft position and a control unit which outputs a required angle based on engine parameters. It calculates the difference between actual and required angles and the result is the basis of the camshaft adjustment. However, the signal is first multiplied by two correction factors, one derived from a simple function of the oil temperature and speed, the other from a more complex function of the same parameters.
