Patent DE-4137156-A1 (DE)
Title: Polystyrene concrete plates -  formed by pouring polystyrene concrete conveyor with inserted fabric and light steel reinforcement and cutting to length when set
Inventor: KESTING LORENZ
IPC: B28B23/00
Filed: 1991-11-12
Abstract: Polystyrene concrete plate for construction applications, with a reinforcement of a light steel structured profile to form intermediate supports, is formed by pouring the polystyrene concrete into an open basin contg. the reinforcements, in a continuous pour to form a length while the longitudinal sides are contained. During pouring, a woven fabric is inserted into the material as an additional reinforcement. When the material has hardened, lengths are cut off as plates. The shorter sides of the plates are aligned across the line of the poured material. The concrete is laid in a number of layers, and the reinforcement material is laid from above into one of the layers, to be covered by the next layer of concrete. The reinforcement is laid where tensile stresses are anticipated, and the light steel profiles can be over, under or between reinforcements. The concrete and the reinforcement are stationary on the underlay, and the material hardens between the concrete feed and cutting points. The upper side of the concrete strip is covered, to give the surface structure required to be seen, and a fabric reinforced plaster layer is on one side of the concrete plate, or one side of the concrete plate is covered with plates which remain as a cladding. The additive to the concrete is in the form of pelletised domestic rubbish. At least part of the concrete is replaced by plaster in the form of an alpha-semihydrate. Structural steel can be inserted between fabric layers within the polystyrene concrete as further reinforcement. ADVANTAGE - The method gives a simple construction plate mfg. process, where waste products can be recycled into building material.

Inventor: BLAZEK VLADIMIR DR
IPC: A61B5/103
Filed: 1992-04-14
Abstract: Light is transmitted into tissue (G) from a sensor (S) into which the electric current is controlled by a modulator and driver stage (1). A measure of the reflected and scattered light is applied as an electrical signal to a current-to-voltage converter (2), filter (3), amplifier (4) and demodulator (5). The demodulated signal is integrated (7) subject to a calibration voltage (Uc) such that in one position (A) of the selector (10) an output stage (14) gives the vol. pulsation of the arterial flow through the illuminated tissue. In the other position (V) the sample-and-hold stage (8, 9) is "frozen" at the calibrated current level and only the low-frequency venous vol. changes are registered. ADVANTAGE - Fluctuations in volumes of arterial and venous blood can be recorded separately.

Title: Radio receiver for SSB reception from DSB AM transmitter - provides equalising compensation by removing interference from DSB oscillation to be evaluated from mixt. or DSB oscillations
Inventor: HEINZMANN GUSTAV DIPL PHYS DR
IPC: H04B1/10
Filed: 1993-02-10
Abstract: The received side band of a desired transmitter is equalised by compensation such that the overlap-free extreme side band of a mixt. of intersecting two-side band oscillation is frequency converted to the other side reversal with a negative sign. Thus the transmitter second side band of the immediately neighbouring channel is freed from overlaps. The equalised side band is then negatively reversed onto the other side of the above channel such that the outer channel side band is equalised in-front of the channel. The negative reversals are continued up to the reception of a single-side band of the desired transmitter. ADVANTAGE - Min. cost for mixers and filters, and without band cutting for reproduced LF.

Abstract: The surge arrester contains two connection armatures (1, 2) separated from each other along an axis, at least one cylindrically shaped varistor element (7) being arranged between them. The connection armatures (1, 2) and the one or more varistor element(s) (7) are braced together with the formation of a contact force to form a mechanically stable active part of the surge arrester. The active part is enclosed by a cast housing (12) made of insulating material. The active part is braced by at least two loops (5) acting independently of each other on the connection armatures (1, 2). The loops (5) are arranged with a separation from the one or more varistor element(s) (7). The connection armatures (1, 2) contain bearing surfaces, in each case corresponding to the number of loops (5) and azimuthally distributed regularly about the axis, one loop end being supported in each case on one of these bearing surfaces. In spite of simple design, the surge arrester exhibits good mechanical and electrical properties and can be produced in particularly cost-efficient ways. <IMAGE>
