Patent DE-3828375-A1 (DE)
Title: Locking device for seat rails in vehicle seats, in particular motor vehicle seats
Inventor: KLUETING BERND ING GRAD
IPC: B60N2/08
Filed: 1988-08-20
Abstract: The locking device is used in a seat rail which has a guide rail to which a toothed rack is securely connected. A toothed pinion which is assigned to the seat component and can be locked in its set position intermeshes with this toothed rack. A locking device is to be provided with which it is possible to release the connection between the guide rail and the seat independently of the set position for the longitudinal displacement of the seat and with which it is also possible, after the release phase has ended, to achieve a secure locking position between the vehicle seat and the floor of the vehicle. The toothed pinion which is mounted in a cavity of the running rail which is mounted in a longitudinally displaceable fashion in the guide rail is rotationally connected to claw rings which can be axially displaced on both sides of the running rail and can engage in claws which are arranged on both sides of the running rail and are offset in terms of pitch with respect to one another, the said claw rings forming the locking element. A locking device of this kind permits, when released, simple longitudinal displacement of the seat with respect to the floor of the vehicle without a separate adjustment device being required for it. When locked, it is ensured that one of the claw rings reliably locks the seat with respect to the floor of the vehicle immediately when the locking device is correspondingly actuated.

Title: Tool protection for the tools of cutting or forming presses, mainly for metalworking
Inventor: SCHWARZ SIEGFRIED
IPC: B30B15/00
Filed: 1988-09-29
Abstract: Tool protection for the tools of cutting or forming presses (PR) in metalworking is created by the allocation of a socket (D) with its own intelligence and its own, programmable memory to each tool (W). The respective press control unit (ST) therefore requires only the storage location for the data of a single tool. <IMAGE>

Title: Clamping head for the clamping of tensile samples in tensile testing machines
Inventor: HECK SIEGFRIED
IPC: G01N3/04
Filed: 1988-10-07
Abstract: Hydraulically actuated clamping heads in tensile testing machines offer advantages with respect to mechanical ones. They permit speedier working with more uniform results. Large weight and volume at a high price have limited their area of application until now. In the clamping head according to the invention, Figure 1, the connection between the carrier (1) and the clamping cylinder (4) is carried out by means of the tension armatures (2) and (3), which are arranged in a diagonal plane symmetrically and parallel to the clamping piston axis (25). The symmetrical distribution of pressure forces and tension forces achieved by this means makes possible a light, compact and easily-produced clamping head, in which no bending forces occur. The arrangement of the tension armatures (2) and (3) allows feeding of the shoulder rods (17) unhindered by the clamping head in the case of automated operation, and a problem-free attachment of the probes of the strain gauge pick-up. The clamping piston (6) is provided with a head plate (5) which is guided on the tension armatures (2) and (3) by means of the guide (28). A tensile force introduced from the clamped shoulder rod into the clamping jaw (10), at an angle to the clamping piston axis (25), is taken up directly by the tension armatures via the head plate (5) by means of the guide (28), which prevents canting of the clamping piston (6). <IMAGE>

Title: Method and device for the faultless measurement of torque on a shaft
Inventor: GERRATH KARL-HEINZ DR
IPC: G01L3/10
Filed: 1989-03-10
Abstract: Method and device for the faultless measurement of torque on a shaft by means of the determination of the relative twist between two separated points on the shaft caused by a torque acting, the measuring signals indicating rotation of the shaft being picked up with a predetermined phase difference at each of these points in a plane respectively perpendicular to the shaft with the aid of two fixed sensors, the sensors being aligned in a plane to those of the other plane in such a way that the measured signals of the one plane have a phase difference with respect to those of the other plane which is different from the phase difference from the signals of one plane, phase differences of 180@ being excluded. According to an equivalence or antivalence function, a logical coupling is then made, first of the measured signals of one plane, converted into pulse signals, and then of the coupled signals of both planes, phase shifts caused both by mechanical displacements and also by offset being compensated in the averaged output signal and the mean value of the torque being indicated faultlessly.

Filed: 1989-04-19
Abstract: If text service information items and user guidance information items are simultaneously shown on the screen in the currently used television receivers which have a ratio of picture width to picture height of 4:3, some of the text service information items actually to be displayed must be masked out. In the novel device, this masking out should not be necessary. Essentially, this is achieved by the fact that the text service information items are displayed in 4:3 format on a wide format television screen which has a ratio of picture width to picture height which is greater than 4:3, and the read-out process of the information items, stored in a memory, which are to be displayed overall on the wide-picture television screen is controlled in such a manner that the user guidance information items and the text service information items are present in time-division multiplex within the television lines. <IMAGE>

Title: Process and apparatus for recording and reproducing data onto and from a magnetic tape by means of a rotating head
Inventor: SUDOH KENGO
IPC: G11B5/008
Filed: 1989-06-21
Abstract: In the recording of data on a magnetic tape (20) along helically running tracks with the aid of rotating magnetic head means (19a, 19b), two tracks (Ai, Bi) respectively form a frame (Fi) which represents a unit during the signal processing. Each of the tracks is subdivided into a first region (Dai, Dbi) and into at least one second region (Sai to Sdi). Main data are recorded in the first region, while subdata are recorded in the second region. These subdata contain the data length of the main data in the associated frame, the data marking the beginning of the data, which indicate the presence or absence of the beginning of the main data in the frame, and the data marking the end of the data, which indicate the presence or absence of the end of the main data in the frame. If a number of main data regions are recorded on a magnetic tape, a subdivision of the main data can be detected from the subdata even if no control data are recorded in a gap between the main data, with the result that the storage capacity of the magnetic tape can be better utilised. <IMAGE>
