Patent DE-3125651-A1 (DE)
Title: Method and device for intensive heat and substance exchange
Inventor: AKERET RUDOLF DR ING
IPC: F27B9/28
Filed: 1981-06-30
Abstract: A pipe (R) for intensive heat and substance exchange is flowed through by gas. The pipe (R) contains an inlet opening (12) and two outlet openings (11, 13) for the gas. The solid body (G), which is in exchange with the flowing gas, enters at (1) into the pipe (R) of a length (L) of 0.5-100 m, passes through a number of screens (14) which are arranged at a spacing of 0.05-0.5 m and narrow the cross-section of the pipe (R), and emerges again at the end (2) of the pipe (R). The screens (14) form, with the surface (3) of the solid body (G), gaps (15) of 3-50 mm which are delimited by the layer of the gas on the solid body (G), which reduces the exchange. Between each two adjacent screens (14), chambers (18) arise, in which the gas rotates and thus acts repeatedly on the solid body (G). As a result, the exchange efficiency is further improved. With this system which works in counterflow, the solid body (G) passing through can absorb and deliver heat, absorb and deliver gaseous substances, according to the nature of the gas flowing through the inlet opening (12). The main application areas are, however, heating and drying of a solid body (G). <IMAGE>

Title: Thread-guide folding device
Inventor: DINKELMANN FRIEDRICH DIPL ING
IPC: D01H13/16
Filed: 1981-07-02
Abstract: The invention relates to a thread-guide folding device in the region of a spinning station of a ring-spinning machine, with a bearing part arranged on the actuating frame and with a foldable pivoting part which holds the thread guide and on which a thread sensor is arranged. This thread sensor can be connected to an indicating or actuating device via an actuating element and via an electrical switching member. At the same time, the actuating element (9) and the electrical switching member (10) can be connected operatively via a magnet (11), the actuating element (9) being arranged on the pivoting part (5) of the thread-guide folding device and the electrical switching member (10) being arranged in the bearing part (3). A flexible electrical connection between the fixed bearing part and the foldable pivoting part can thus be avoided. <IMAGE>
Patent DE-3129064-A1 (DE)
Title: Method and device for the oxygenation of blood
Inventor: OSTERTAG KARL DR DIPL ING
IPC: A61M1/18
Filed: 1981-07-23
Abstract: Method and device for the oxygenation of blood by means of a gas-permeable diaphragm, the oxygen diffusing through the diaphragm into the blood and the carbon dioxide being removed from the blood through the diaphragm, and the blood being cooled or warmed by the heat transfer from the blood or to the blood taking place via the oxygen as indirect heat transfer medium, and the oxygen supply and removal of carbon dioxide taking place simultaneously with the heat transfer and through the same diaphragm. Transport of matter and heat thus merely requires one transfer unit for which diaphragms which are conventional per se, for example in film form or in the form of hollow fibres, can be used. As a result of the invention, the blood volume to be kept outside the patient's body and the exogenous contact surfaces coming into contact with the blood are much smaller than in the known methods and devices, and only one transfer unit needs to be discarded after use. The essence of the invention is depicted in Fig. 1. <IMAGE>

Title: Circuit arrangement for the analog/digital conversion of the value of a resistance
Inventor: FAUSER EDWIN ING GRAD
IPC: H03M1/00
Filed: 1981-07-25
Abstract: A circuit arrangement for the analog/digital conversion of the value of a resistance, particularly of the measuring resistance (RM) of a temperature sensor, is proposed. In this arrangement, an integrator which is driven with a reference input signal of a first polarity in a reference phase and with a measurement input signal of opposite polarity in a measuring phase is used in a manner known per se, a measurement value finally being formed from the ratio of the time of reference and measuring phase. In this arrangement, currents are used as input signals, namely a reference current formed from a reference voltage (UB) and the input voltage of the integrator via a reference resistance (RR) as reference signal and a measuring current formed from the input voltage of the integrator via the measuring resistance (RM) as measurement signal. The input voltage of the integrator is constant and is obtained from the reference voltage (UB) by means of a voltage divider (R1, R2). <IMAGE>

Title: Liquid crystal display having a transmissive cell
Inventor: WALTER KARL-HEINZ DIPL ING
IPC: G02F1/1347
Filed: 1982-07-28
Abstract: The following arrangement is proposed in order to be able to use a display based on liquid crystals to represent graphic or alphanumeric information with an image spot number of >10<4>: a storage cell (3) having a photoconductive layer (21) ("light valve") is situated in front of a write cell (2), which is illuminated from behind and contains an electrode matrix. The write cell is addressed using a special multiplex technique. The row conductors (13) are subdivided into groups, each group being multiplexed in conventional fashion, and during the transition from one to the next group a timing pause is inserted which is of the order of magnitude of the relaxation period of the liquid crystal. Such a display device has a relatively simple, compact design and can be operated with a relatively low degree of multiplexing. Main application area: highly informative displays (videophone, office communications). <IMAGE>

Title: Safety window crank
Inventor: BOSSERT WALTER DIPL ING
IPC: G05G1/08
Filed: 1982-10-20
Abstract: A safety window crank consists of two parts: a crank arm (10) which can be connected to an axle journal (11) and of extremely flat design and a cover element (30) engaged on this and having a rotary knob (32). The engagement is designed so that, in the event of a relative displacement between the cover element (30) and crank arm (10), it is released and the cover element (30) thereby falls down. To prevent such a relative movement during normal operation, there is a shearing pin (41) which is sheared off and then allows the cover element (30) to fall down only when a force F2 of specific magnitude (accident) occurs.
