Title: Relay operating circuit for high resistance power source - has relay operating RC circuit initiated by second RC circuit which switches transistor
Inventor: TRETOW JOCHEN ING GRAD
IPC: H01H47/04
Filed: 1979-07-17
Abstract: The equipment is for operating a relay from a high resistance energy source, for example in the mining industry where minimum battery is necessary. The energy source (1) charges a first RC circuit (5,6) through a current limiting resistor (2) which has a time constant tau 1. A second RC circuit (3,4) with a time constant tau 2, is also charged by the same high resistance source (1,2). Time constant tau 2 is 10 x tau 1. The relay (7) and switching transistor (8) together with base resistor (10) are in parallel with the capacitor (6) of the first RC circuit (5,6). When the operate switch (9) is closed, the first RC circuit charges but does not operate the relay (7) until the second RC circuit has charged to switch on the transistor (8). The fully charged capacitors (6) discharges to operate relay (7) through transistor (8). The energy source holds the relay operated.

Title: Dampness level measuring arrangement - has two oscillators generating neighbouring microwaves with one changing when measuring object is inserted
Inventor: HOPPE WOLFGANG ING GRAD
IPC: G01N22/04
Filed: 1979-10-24
Abstract: The simple measuring arrangement achieves the necessary temp. and frequency stability for industrial measuring of the absolute and relative moisture content of yarn and foil type materials. The oscillators are used to generate two neighbouring frequencies One produces an H-oscillation in the measuring chamber while the other produces an E-oscillation.

Title: Detector for mechanical oscillations using piezoelectric effect - has semiconductor support with recess, overlapped by thin measuring transducer affected by mechanical oscillations
Inventor: FUJISHIMA SATORU
IPC: H04R17/02
Filed: 1980-02-20
Abstract: The support (1) of semiconductor material for the oscillation detector has a reces, and carries a thin measuring transducer (3) of piezoelectric material, picking up mechanical oscillation from an external source. The transducer overlaps a portion of the recess and transmits an electric signal corresponding to the oscillations picked up. In addition to its thin layer body (5) the transducer carries on both surfaces electrodes (4, 6), one electrode (4) being arranged on the support. This electrode may be deposited by printing techniques. After deposition of the measuring transducer, the recess may be formed by etching, typically after deposition of the first electrode. The electric signals may be amplified by a transducer-connected amplifier (7). The production starts with deposition of a first electrode layer on the semiconductor support followed by forming the recess in the latter in a porton underneath and round the first electrode region. Then the electrode is coated with a thin piezoelectric layer, and finally the second electrode layer is deposition on the latter.

Title: Exposure detail projection into SLR viewfinder - has light guide in front of penta-prism and has integral illumination
Inventor: KIMURA MAKOTO
IPC: G03B19/12
Filed: 1980-04-08
Abstract: An addition to the front of an SLR camera projects the objective settings into the viewfinder using a simple light guide (13) with inlet surfaces for outside and internal illumination and outlet surfaces for the data. The image is projected into the front of the viewfinder housing and from there into the prism using angled mirrors. The data viewer is separate from the viewfinder, which can be replaced without affecting the data input. The internal light (13a) provides illumination when the flash mode is selected while a large front surface (13f) of the light guide collects normal daylight for normal exposures. The viewer provides a direct indication of the objective settings without any complex mechanical or electric links.

Title: Spark ignition IC engine - has centrifugally governed damper in inlet to maintain efficiency over range of speeds
Inventor: VACEK BOHUMIL
IPC: F02D9/02
Filed: 1980-04-29
Abstract: The engine has cylinders arranged in line with a suction manifold supplied from a carburetter (4) with a throttle (3). A damper housing (2) with a sliding blade (1) is placed between the carburetter and the manifold. The operating rod (6) of the blade is connected to a centrifugal governor (5). The engine inlet is thus regulated according to speed and this maintains the volumetric efficiency and thus the compression ratio. The efficiency is thereby maintained over the entire range of engine speed and the engine can be designed with a higher compression ratio. A manual control (10) on the governor adjusts it for stopping and starting. Specification printed 25.3.82.

Title: Salt glaze prodn. on earthenware - by burning applied salt-contg. coating in automated ceramic electric furnace
Inventor: RASBACH GEB BERG
IPC: C04B41/50
Filed: 1980-05-24

Title: Functional testing of vehicle oscillation dampers - by measuring oscillation speeds and comparing with characteristics of undamped vehicle
Inventor: HERTERICH MANFRED
IPC: G01M17/04
Filed: 1980-06-21
Abstract: A method and arrangement for functionally testing vehicle suspension oscillation dampers involve stimulating the part of the vehicle associated with each damper. The condition of the damper is evaluated from the frequency of oscillation. The effective damping of each damper is measured irrespective of the total suspension damping and the total chassis damping. The oscillations are fed into the suspension system in the sub-critical region in a conventional manner. The test system makes several measurements at different oscillation speeds. From these measurements the mechanical friction in the suspension and the hydraulic damping of the damper are established by forming differences. The differences are produced taking account of data specific to the vehicle obtained in the absence of a damper.

Title: Desalination and ion concentration of sea water - by Lorentz force accelerating positive and negative ions in opposite directions
Inventor: KARR DIETER DIPL PHYS
IPC: C02F1/00
Filed: 1980-08-22
Abstract: Plant for the desalination of seawater and for the prodn. of an ion concentration gradient in a non-magnetisable electrolytic fluid is based on passing the fluid at right angles through a powerful magnetic field. A relative velocity between electrolyte (seawater) and magnetic field causes the Lorentz force to accelerate the ions of the electrolyte at right angles to the direction of motion. This system has a lower power consumption than evaporation, osmosis or electrodialysis systems and is able to operate continuously.

Title: Method for transmitting time division multiplex signals in a digital telecommunications network
Inventor: KLIEM HELMUT DIPL ING
IPC: H04Q11/04
Filed: 1981-01-14
Abstract: Individual channels of a primary time division multiplex system, e.g. the 64 kbit/s channels of a primary PCM time division multiplex system, can be switched individually and as required on the basis of individual clock adaptation in the network nodes. For this purpose, the clock speed of each time division multiplex signal arriving in an exchange is adapted to the speed of the respective network node by inserting or omitting padding characters, an adequate supply of which is obtained on the first adaptation. The elimination of all padding characters from the time division multiplex signals and the removal of the padding character gaps are carried out in the destination exchanges.
