Title: Distance measuring device for non-touching (contact-free) distance measurement
Inventor: RAPPS PETER
IPC: G01S15/931
Filed: 1988-03-03
Abstract: The invention relates to a distance measuring device for non-touching distance measurement, especially for measuring the distance between two motor vehicles, ultrasound signals which are offset by specific time intervals and are at at least two different ultrasound frequencies (f1, f2...fN) being emitted from an ultrasound transmitter (I, II...N), which frequencies are identified on the basis of their different frequencies and are recorded by the ultrasound receiver. A separate delay-time measurement (counter 8...N) is carried out in each case for each ultrasound signal of different frequency, and the measurement results are fed to an evaluation device (microprocessor 18). The use of time-offset ultrasound signals of different frequency allows the measurement frequency of the overall arrangement for unambiguous measurements results to be increased, which is essential especially in the case of rapidly changing measurement distances as arise when measuring the distance between vehicles. <IMAGE>

Title: Tyre with variable centre of mass
Inventor: MEYER DIETER
IPC: A63B19/00
Filed: 1988-03-25
Abstract: A tyre with a variable centre of gravity consists of an annular hollow body in whose inner cavity a vacuum exists or which is wholly or partially filled with gas and/or a liquid. In the vacuum, or in the gas or liquid, is a weighted piece which is freely movable within the cavity. The effect of the weighted piece is that the centre of mass always deviates greatly from the geometrical centre of the item of equipment and likewise changes when the weight is displaced within the hollow body. If the tyre, which is preferably to be used as sporting equipment, is set in motion, changing muscle stresses are necessary when the equipment is lifted in order to compensate for the shifts in centre of gravity. When the equipment is rotated about an eccentric centre of rotation which lies within the tyre, the rolling of the tyre on the centre of rotation and hence the shift in the centre of gravity is compensated by sliding of the weighted piece within the cavity in the tyre. As a result, the mass centre rotates concentrically at the same distance about the centre of rotation. The rotation of the tyre is, therefore, always very stable even at low angular velocities about the centre of rotation, because of the uniform centrifugal forces. The equipment is not only outstandingly suitable for many gymnastic exercises, especially for untrained, young or delicate people, but also, because of the very simple handling and low cost to be expected ...

Title: Device and circuit arrangement for detecting the formation of black ice
Inventor: KASPAR SIEGFRIED
IPC: B60R99/00
Filed: 1988-05-07
Abstract: Known devices and circuit arrangements for detecting the formation of black ice on streets have a temperature sensor which generates a signal when the temperature drops below freezing point. The signal is, however, also generated in dry weather. In contrast, a signal can remain absent in spite of the formation of black ice, if the black ice formation occurs as a result of a temperature of the street surface being below freezing point, although the air temperature lies above it. In order to avoid this, it is proposed to mount on the vehicle a frame which carries on its bottom side two rollers (1) insulated electrically from each other, the rollers being electrically conductive and being in contact with the street surface. These rollers are connected to an electrical resistance measuring device, which generates a signal as soon as an electrical resistance value which points to ice formation is detected between the rollers. <IMAGE>

Patent DE-3829299-A1 (DE)
Title: Basting device
Inventor: TRIEBE GEORG DR
IPC: B67D99/00
Filed: 1988-08-30
Abstract: Cam control systems of the covering devices of the generic type are accommodated in a region which is separate from the cooking chamber. This means that a considerable volume of useful space is lost. Between the cooking chamber and the mechanism chamber there must be provided a passage which approximately corresponds to the path of motion of the basting ladle. Energy losses, problems with hygiene and problems of electrical installation are the results of this. The object of the invention is to develop a drive which will make it possible to establish an easily sealable connection between the drive chamber and the cooking chamber. The object is achieved according to the invention in that the basting ladle (8) takes the form of the outer surface (10) of a horizontal prismatic structure, the base and/or limiting surfaces (9) taking the form of sectors of a circle and, in the centre of the circle from which the sector is derived, the basting ladle (8) being fixedly connected to the ladle arm (6) and the outer surface (9) facing the pouring-out device being enclosed. The invention is suitable for cooking devices, in the case of which the material to be cooked is basted with a liquid during the cooking process. <IMAGE>

Title: Detection and reduction of defects in sound irradiation in headphones
Inventor: KOENIG FLORIAN DIPL ING
IPC: H04R3/00
Filed: 1989-02-03
Abstract: A method or reducing the signal distortion occurring in the irradiation of the outer ear by means of headphones, in which, in addition to the known graphical sound assessment by listeners by means of determination of the propogation constant, the diaphragm pulse response and the transient response of the outer ear in the case of sound irradiation by headphones is additionally used for checking the multi-dimensional reproduced sound fields artifically generated by headphones which are as natural as possible. Findings related to the ideal measure which, in particular, relate to sound irradiation defects and are obtained by measurements and which are obtained compared with the free incidence of sound at the outer ear enable a subsequent optimisation of the sound irradiation to be designed for the transmission of sound from the headphones to the outer ear by means of a suitable signal processing device.
Patent DE-3903379-A1 (DE)
Title: Clamping system for clutches and shaft/hub connections
Inventor: RUEHLEMANN JOACHIM
IPC: F16D41/06
Filed: 1989-02-04
Abstract: The proposal is for a clamping system which is suitable for the construction of clamping elements or clutches. The operative part of a clamping element consists of a multiple disc assembly which, with the same performance as known assemblies, provides new possibilities for assembly and hence possible uses while involving only a low outlay on manufacture. These possibilities for assembly result in an approximate halving of the possible assembly tolerances and hence improve the running quality of the shaft/hub connection, and the lowering of the cost of assembly is another advantage. The functional basis of the clamping system is the self-reinforcement of the friction under certain circumstances, thereby automatically providing a loadable connection between the shaft and the hub as a function of the load without the contribution of additional screw forces. The system offers the possibility of being able to mould discs made of plastic directly to a plastic hub.

Title: Deep-hole hammer drill with water-flushing arrangement
Inventor: ZIMMERMANN JUN FRITZ
IPC: E21B21/12
Filed: 1989-02-20
Abstract: Deep-hole hammer drills with a central flushing bore or with a flushing passage directed past the percussion mechanism only allow a small quantity of flushing medium to flow through on account of designs possible. In addition, these embodiments are characterised by high susceptibility to trouble and poor drilling performance at high energy consumption. The invention relates to a deep-hole hammer drill according to Fig. 1, in which the flushing medium, e.g. water, is directed via an adaptor 11 into the flushing passage 12 of the connecting sleeve 9 to the annular space 13 between hammer drill and casing tube 7 into the water-flushing passage 14 of the front housing 3 and further through the flushing passage 15 of the percussion bit 2 to the borehole bottom. A second embodiment according to Fig. 2 allows the flushing medium to discharge from the casing 7a at the bottom end of the front housing 3. On account of this invention, it is possible to direct a multiple quantity of flushing medium to the borehole bottom, drill through homogeneous deposits without problems and also use the hammer drill for methane drainage bores in mines.
