Patent DE-4021822-A1 (DE)
IPC: A47K3/02
Filed: 1990-07-09
Abstract: In long bath tubs, the problem exists that persons of short physical stature cannot assume a comfortable recumbent position. It is proposed that the end wall (4) defining the interior space of the tub make a transition by means of at least one step into at least one longitudinal side wall (1, 2) and form a foot part (10) which is stepped in the longitudinal direction of the bath tub. As a result, a secure support for the feet, and hence a comfortable position in the bath tub, are provided even for persons of short physical stature. <IMAGE>

Title: Automatic head position adjuster for dot-matrix printer - uses contact sensor to measure paper thickness before paper reaches printing position
Inventor: DUESTERHUS RICHARD
IPC: B41J25/308
Filed: 1990-07-23
Abstract: A thickness sensor (38), which incorporates a strain gauge or piezo-electric transducer, is mounted below the printing position and can thus perform measurements before the paper reaches the printing head (24).

Title: Surgical needle - has body with point and spring lug whose side parts form thread slot
Inventor: FUHRMANN WOLF-DIETER
IPC: A61B17/06
Filed: 1990-10-20
Abstract: The spring lug (3) is formed by two side parts (5), which represent the upper end of the needle body. The side parts form between them the actual lug and a slot (6) running longitudinally in the centre of the body. Through this slot a tensioned thread (F) can be drawn transversally to its length, thus causing the side parts (5) to be drawn apart. In this way, the thread enters the lug, although in normal circumstances the width of the slot is smaller than the dia. of the thread. In order to facilitate the introduction of the thread in the slot, the two sprung side parts are formed with inclined surfaces (7). USE - As a surgical needle.

Filed: 1991-02-12
Abstract: The compound membrane body, esp. for electrochemical sensors, consists of a housing in which two membranes (4, 6) are clamped and sealed wrt. an electrolyte chamber. Two membranes with different properties are clamped without folding and sealed by applying a sealing ring (5) using a threaded press. element (2). Accurately defined tensions, and hence an acurately defined electrolyte film, are achieved by the press. of the sensor (3) tip on the membranes. Insertion of the ring between the membranes ensures that they can have different tensions and extensions. USE/ADVANTAGE - E.g. for oxygen measurement. Enables use of different membrane tensions.

Title: Pulse compression and expansion circuits for infrared remote control - compresses pulses prior to transmission and expands them after reception to increase usable bandwidth
Inventor: CZERNY HERIBERT DIPL ING
IPC: H04B10/114
Filed: 1991-02-21
Abstract: Switch control signals (1) are converted into pulse code modulation (pcm) signals by a proprietary encoder (2) and passed to a pulse compressor (3). The pulse compressor comprises an OR-gate fed by a leading-edge triggered monostable in parallel with a trailing-edge triggered monostable. The time duration of both monostables just exceeds the nominal pcm pulse width and, when combined by the OR-gate, generate a leading and a trailing edge spike for each pcm pulse. These spikes are passed to an infrared transmitter (4), transmitted to an infrared receiver (5), amplified and passed to a pulse regenerator (6). The pulse regenerator comprises two monostables and a D-type flip-flop which convert the incoming edge spikes into full-width pcm pulses and passes them to a decoder (7). If the incoming pulse code agrees with the switch settings on a coder (8), the decoder activates a relay (9). USE/ADVANTAGE - Enables proprietary pcm encoders to be incorporated in narrow pulse width transmission systems.
Patent DE-4109432-A1 (DE)
Inventor: PFALZGRAF BERNHARD DIPL ING
IPC: F02P5/153
Filed: 1991-03-22
Abstract: The invention relates to knock regulation in a spark-ignited internal combustion engine with a short-term regulation with a relatively large regulating action (periods a, b, c, f), in which, when knocking events occur, the value for an actual ignition point is taken back from a predetermined characteristic diagram value ( alpha v) in the direction of retarded ignition (SK1). In the absence of knocking events, the actual ignition point is returned in the direction of advanced ignition to the predetermined characteristic diagram value (RK1). According to the invention, long-term adaptation is carried out such that the predetermined characteristic diagram value ( alpha v) is taken back from the knock limit by an adaptation value (LZ) or modified when knocking events (K) occur, so that the short-term regulation is related to a new predetermined ignition point value or another level ( alpha LZ). There is a change-over to a smaller regulating action (period e; SK2), RK2) after an adaptation has been effected and after a minimum number of knockless ignitions (area d). A more advanced ignition angle and improved efficiency of the internal combustion engine is thus achieved on average.
Patent DE-4109680-A1 (DE)
Inventor: JUNG RUEDIGER DIPL ING
IPC: F15B13/01
Filed: 1991-03-23
Abstract: The valve has at least two pistons 2, 7 which are under the action of at least one stored-energy device 10, 11 which attempts to hold the pistons against one another. Furthermore, the valve has at least two fluid-conducting connections A, B, of which the first connection A can be connected to a tank, the closing force of the valve increasing up to a predeterminable maximum value as the load pressure prevailing at the second connection B increases. Owing to the fact that means are provided which keep the maximum value of the closing force constant as the load pressure prevailing at the second connection B continues to increase, the valve can also be used for ranges of application having stringent safety requirements. <IMAGE>

Patent DE-4115793-A1 (DE)
Inventor: GITTLER GUENTER
IPC: G01C11/00
Filed: 1991-05-10
Abstract: This arrangement is intended, in particular, for image processing type measuring systems for recording objects with the highest geometric measuring precision. It is used in industrial measuring techniques for quality control and in high-precision optical instruments. According to the invention, the geometric structure of a two-dimensional sensor array is used as material measure for the measuring task, in which a microscanning system (9) comprising x-y translators (91,92) and measuring system realises shifts in sensor array position, derived from the material measure, compared with the original position by defined fractions of the centre-to-centre spacing between adjacent sensor elements, and the recorded measurement values of the image acquisition channel are correlated with the actual position values in the image analyser (7). The microscanning is synchronised with the sensor sequence control and can be carried out in a closed control loop to avoid hysteresis. A diaphragm array partially limiting the individual sensor element apertures in a defined manner can also be used for non-metric sensor matrices up to a CCD frame transfer matrix. <IMAGE>
