Title: Toothbrush
Inventor: SCHAIPER HEINRICH
IPC: A46B7/06
Filed: 1987-11-03
Abstract: The invention relates to a toothbrush with a brush head (11), brush handle (12) and brush gripping part (13) such that both the brush gripping part and the brush handle and brush head comprise adjacently arranged elements (21) and (22) which transmit the relevant brushing pressure from the brush handle to the teeth to be cleaned. Between the elements (22) and (21) there is a highly suitable material of extreme flexibility (23) which permits torsion of the elements (21) and (22) relative to one another due to the consistency and design of the material. This torsion permits an incorrect angular position of the brush head relative to the teeth to be compensated flexibly and makes it possible to avoid or suppress sawing of the necks of the teeth in horizontal brushing techniques. <IMAGE>

Title: Trap for catching animals
Inventor: LUEKE JOHANNES
IPC: A01M23/26
Filed: 1987-12-28
Abstract: The animal trap exhibits two bows (1, 1a) which consist of flat iron members or round iron members, are mounted, such that they can pivot about mutually opposite pins (5, 5a), opposite one another in metal hinge plates (4) and are subjected to stressing by two springs (3) in the form of flat leg springs or helical leg springs. The two metal hinge plates (4) are kept at a distance from one another by a connecting web (15) which forms the central longitudinal axis of the trap and is in the form of a flat iron member or tube, and mounted movably on said connecting web (15) is a release mechanism with a bait-receiving means (26), which interacts in a locking manner with a bow (1) in the bracing position. By virtue of the offset pin mounting (5, 5a), one bow (1a) acts as rest bow and the second bow (1) acts as striking bow in that the latter, with simultaneous rotation of the trap about the pins, strikes the animal and kills the latter at the corresponding point. <IMAGE>

Title: Engine hydraulic bearing
Inventor: ADEN BODO DIPL ING
IPC: F16F13/20
Filed: 1988-01-16
Abstract: The invention relates to an engine hydraulic bearing with a bearing core serving for engine fixing, an annular spring element and an abutment which can be fixed to the vehicle body side. At the same time, a working chamber filled with hydraulic fluid is provided and a fluid-filled compensating chamber of variable volume separated from the former chamber by a dividing wall. In addition, a throttle orifice is provided, which connects the working chamber to the compensating chamber, whilst the dividing wall accommodates a displaceable diaphragm which, actuatable by means of adjusting elements, can be brought, at least temporarily, into extensive contact with a bearing surface of the dividing wall impeding the diaphragm's facility for free deflection, and especially in higher engine speed ranges constantly bears on the dividing wall, and at low engine speeds is supported so that it is free to oscillate. If the diaphragm is then brought to bear briefly on the dividing wall also during the engine starting and/or shut-off sequence, it is thereby possible to ensure in an especially cost-effective manner that optimum bearing characteristics exist in all engine operating conditions and in particular, that the disturbing impact of the diaphragm on its dividing wall bearing surface during starting and/or shutting off of the engine and the large vibration amplitudes associated therewith can be reliably avoided.

Title: Arrangement of an optical fibre phase sensor for measuring minimum expansions (extensions)
Inventor: FEDERMANN HELMUT DR
IPC: G01L1/24
Filed: 1988-03-05
Abstract: The measuring device according to Patent Application P 3638345.7, in which polarised light is coupled into an optical fibre sensor and the change in phase difference occurring in the event of a change in length of the optical fibre is determined, consists of the following parts connected in series: transmitter, optical fibre, phase sensor, optical fibre, receiver and measuring device. This device is to be developed such that it can be used to carry out an accurate determination of measured values. Furthermore, an alternative line connection is to be specified between the phase sensor at the measurement object and the measuring device in the control room. The object is achieved when the one receiver is replaced by three receivers (71-73), the light beam coming from the optical fibre sensor (4) is divided by means of a beam splitter (grating (16) or optical block) into three component beams (18), and component beam 1 impinges on the associated receiver directly, beam 2 impinges through a  lambda /4 plate (17) and an analyser (52), and beam 3 impinges through an analyser (53). Furthermore, instead of the optical fibres, it is possible to use Cu line connections (19), the optotransmitter and optoreceiver (1 and 7, respectively) being integrated in the phase sensor instead of in the measuring device. The device is used for exact determination of measured values of minimum expansion, principally on parts of aircraft or bridges. <IMAGE>

Title: Tyre-pressure monitor for multiple pneumatic tyres
Inventor: ACHTERHOLT RAINER
IPC: B60C23/04
Filed: 1988-07-22
Abstract: A tyre-pressure monitor (10) serves to indicate the decrease in the tyre pressure in one or more tyres of a multiple pneumatic tyre. For this purpose, a chamber (30) is formed in the housing (11) of the tyre-pressure monitor (1) for each pneumatic tyre, the chamber being subdivided by a diaphragm (35) respectively into a pressure space (36) which cannot be separated from the tyre air-pressure and respectively into a reference space (38) which can be shut off from the tyre air-pressure. Inside the housing (11) there is, furthermore, an adjustable pressure plate (40) whose adjustment shuts off a flow connection between each reference space (38) and the connecting channel section (23) assigned to this. After inflating to a desired tyre pressure and closing each reference space (38), any decrease in pressure in the assigned pressure space (36) caused by a decrease in air pressure in one or more pneumatic tyres causes the diaphragm (35) to approach a transparent housing section (50) respectively assigned to each pneumatic tyre. This approach of the diaphragm is optically detectable through the transparent housing section (50) and serves as an indication of a pressure decrease in a specific pneumatic tyre. In the housing (11), a pressure equalisation chamber (60) can additionally be designed, which permits automatic pressure equalisation between different tyres within a restricted pressure range, before a pressure-decrease indication is generated in the event of further pressure decrease. Additionally, the tyre-pressure monitor (10) ... Original abstract incomplete. <IMAGE>

Title: Method for the alignment of plates conveyed on a transport arrangement into alignment equipment
Inventor: SCHAEFER WALTER DIPL ING
IPC: H05K13/00
Filed: 1988-08-19
Abstract: In a known method for the alignment of plates conveyed on a transport arrangement into alignment equipment, especially of electrical printed circuit boards, the respective plate is guided by means of a slide against a stop and, in the end position condition of the slide, the separation between the slide and a stop is measured. In the event of a deviation of the separation from a predetermined separation (misalignment), the plate is aligned by hand on the transport arrangement. In order to be able to attain the desired alignment in each case automatically, independently of the position of the plates (2) fed to the alignment equipment (1), in the event of a separation characterising a deviation from the desired alignment, the respective plate (2) is pushed onto a rotating plate (9) arranged alongside the transport arrangement (3) and the rotating plate (9) is subsequently rotated through an angle of between 45@ and 90@. Subsequently, the respective plate (2) is again pushed from the rotating plate (9) onto the transport arrangement (3) and pressed against the stop (5) in alignment. The method according to the invention is particularly suitable for the alignment of electrical printed circuit boards in a processing line. <IMAGE>

IPC: G11B33/10
Filed: 1988-10-20
Abstract: Until now, two separate recording-reproducing apparatuses have been necessary for the gapless recording and/or reproducing of messages. In the recording mode, at the end of the recording time of the one recording medium a changeover was performed on the respective other recording-reproducing apparatus manually by the user or by a control device connected via a connecting cable to the two recording-reproducing apparatuses. A conference-recording system is also known in which an overlapping recording was facilitated by delayed switching off of the respective recording-reproducing apparatus. In order to reduce the outlay in terms of circuitry of the recording-reproducing apparatuses and to offer a high degree of user-friendliness, a single recording-reproducing apparatus is provided which has at least two recording means and a control device for switching over between two drives, the drives being driven by the same motor. The control device derives the control commands for switching on and switching over the respective drives from the velocity of rotation of the winding drives of the drives. Thus the recording-reproducing apparatus permits the user to make gapless, in particular overlapping, recordings of messages in a simple manner. The recording-reproducing apparatus can be used, for example for recording telephone conferences or court proceedings and the like. <IMAGE>
