Patent DE-3128992-A1 (DE)
Title: Duplex transceiver device
Inventor: KLOEBER PETER DIPL ING
IPC: H04L27/10
Filed: 1981-07-22
Abstract: The invention relates to a duplex transceiver device for a digitally modulated radio system with only one oscillator for the transmission and reception branches. A device of this type for information transmission between mobile and stationary transceiver stations is intended to be extended so that a full-duplex speech channel independent of the data transmission using the FSK method can also be transmitted. For this purpose, the invention provides a third and fourth frequency condition (f3, f4) of the mobile transceiver station in addition to the two discrete modulation frequencies (f1, f2) of the FSK modulation, the frequencies of the mobile and stationary transceiver stations being disposed in a specific position in relation to one another. A threefold division of the received IF signal is carried out in the reception branch of the mobile transceiver station. This comprises a direct connection via a first changeover switch (12) to a bandpass filter (13) for the IF signal from the two discrete modulation frequencies (f1, f2) and two bandpass filters (9, 10) which are connected in parallel on the input side and which can be connected on the output side via a second changeover switch (11) to a second mixer (7) which is connected to a low-frequency auxiliary oscillator (8). The changeover switches (11, 12) and a digital switching device (16) on the output side, from which the received digital FSK signal can be obtained, are controlled by the signals of the digital transmission modulation. <IMAGE>

Title: Spring element with a spring member made of elastic material
Inventor: MAYER KARL E H
IPC: B60G15/00
Filed: 1981-11-07
Abstract: The invention relates to a spring element with a spring member made of elastic material for the purpose of providing elastic support for stationary apparatus or heavy wheeled vehicles such as straddle loaders, cranes, railway wagons or the like. The spring element comprises a cylinder filled with a fluid or gas and having a displacement piston connected to the frame of the apparatus or the vehicle and displaceable in the cylinder, and an opening formed in that end face of the cylinder which is opposite the pressure face of the displacement piston, which opening is in effective connection with a pressure chamber. The pressure chamber is arranged in a spring chamber similar to a hollow chamber, which has a spring cup with a cup chamber which makes it a hollow body open at one end. The spring chamber is connected to at least one holding device arranged on the apparatus or the vehicle. The spring element makes it possible to convert large initiated spring travels of the apparatus or the vehicle into small spring travels of the elastic material, the specific absorption of work and hence internal friction thereby being reduced. <IMAGE>

Title: Device for determining the wheel diameter of a rail vehicle
Inventor: KRIEG BURCKHARD ING GRAD
IPC: G01B7/12
Filed: 1981-12-07
Abstract: It is important for the exact measurement of the path and speed of vehicles to know the precise wheel diameter of the vehicles. In order to determine this wheel diameter, the wheel pulses triggered during passage of a fixed measuring distance are counted on the vehicle. The pulse rate determined is stored and fed to the setting input (K) of a divider (T1). A high-frequency clock generator (G) is applied for a certain time interval (t) to this divider; in the process, the generator delivers transmission pulses to a downstream counter (Z11). The prescribed time interval is prescribed by a digitally controllable timing element (T) and is dimensioned such that the counter reading established after expiry of the prescribed time interval indicates the diameter (D) of the vehicle wheel. <IMAGE>

Title: Circuit arrangement for processing a signal of an ultrasonic diagnostic unit
Inventor: NAGASAKI TATSUI
IPC: G01S7/52
Filed: 1981-12-19
Abstract: An echo signal which has been emitted by an ultrasonic scanner (11) and reflected by a body to be investigated, is amplified by means of a logarithmic amplifier (15) and amplitude-demodulated by a detector (16). An adder stage (17) adds to the demodulated echo signal an afterecho attenuation voltage, an amplification control voltage and an amplification regulation feedback voltage. The amplification-regulated echo signal passes from the adder stage (17) to a multiplier stage (21) and is multiplied by a dynamic control voltage and a negative dynamic regulation feedback voltage. The negative dynamic regulation feedback voltage is obtained by integrating the output signal of the multiplier stage (21) and subsequently inverting and amplifying the signal. <IMAGE>

Title: Bottle holder for cleaning machines
Inventor: SUESHARDT WOLFGANG
IPC: B08B9/42
Filed: 1982-01-22
Abstract: In bottle holders of this type, special rigidity is achieved by the insertion of crosspieces. To this end, the crosspieces take the form of semi-prismatic or semicylindrical surfaces, and their parts which rest against the section supports and/or limbs are welded to the latter in each case. The insertion of additional welded-on crosspieces necessitates a large manufacturing outlay, however, which should really be reduced in view of the multiplicity of such basket holders in cleaning machines. The invention accordingly makes provision, as shown in Figure 1, for the recesses (5) on the broad side (7) of the holder (1) essentially to correspond to the cross-sectional outline of the bottle cells and preferably to be parallel to the longitudinal axis (9) of the holder (1) on the long side (8) of the latter, with the surface (10) remaining between the recesses (5) having a continuous reinforcement crosspiece (11) formed from the surplus material of the recess (5) on at least one side. The disadvantages of bottle holders described above are avoided by means of the design according to the invention. Despite the use of plastic cells, the additionally welded-in crosspieces, which generally extend between the recesses for the bottle cell, are no longer required. <IMAGE>

Title: KE-Projectile
Inventor: REUSCH RUDOLF
IPC: F42B12/44
Filed: 1982-01-28
Abstract: A KE-projectile comprises a low-calibre penetrator and a sabot surrounding the latter concentrically and means for the releasable connection of the penetrator and sabot. For more cost-effective production of the projectile, the sabot 11 surrounding the penetrator 10 concentrically is made in one piece and is mounted on balls 14, arranged between the penetrator 10 and sabot 11, so as to be axially displaceable in such a way that, in the event of a relative movement of the sabot 11 in the direction of flight of the penetrator 10, the sabot 11 jams the penetrator 10 with the effect of braking the relative movement and, in the event of a relative movement opposite to the direction of flight of the penetrator 10, it releases the latter. This, in contrast to conventional sabots consisting of a plurality of parts, simultaneously reduces adverse influences on the trajectory of the penetrator during the operation of detaching the sabot from the latter. <IMAGE>

Title: Method for improving the bite of a fish hanging on the hook of a fishing line and device for carrying out the method
Inventor: HEUDECKER FRANZ
IPC: A01K97/11
Filed: 1982-07-22
Abstract: In a method for improving the bite of a fish hanging on the hook of a fishing line, as a result of a pull exerted on a fishing rod resting on a support by the fish the fishing rod falls from the support onto a spring device which is in tensioned engagement. The spring device is freed from its tensioned engagement by the weight of the fishing rod and springs back into its position of rest, in the process taking the fishing rod with it. As a result of the sudden jolt exerted by the fishing rod, the hook penetrates deeper into the fish's mouth. The device for carrying out the method comprises a support for the fishing rod, this support extending transversely relative to a push-in leg. Articulated on the push-in leg at a distance from the support is a pivotable retaining member, by means of which a spring member can be tensioned. As soon as a vertical impact force is exerted on the retaining member by the fishing rod falling down, the spring member is freed from its tensioned position, and the springing-back end of the spring member takes the fishing rod with it and clamps the latter between the spring member and push-in leg.
