Title: Two-ramp A=D converter - has shift register and logic circuits to control slope
Inventor: HILLEBRAND RAINER DIPL ING
IPC: H03M1/00
Filed: 1977-10-21
Abstract: An a-d converter comprises a group of resistors (R, R1-3), an amplifier (V) and a capacitor (C). They are connected to form a two-ramp converter. Switches (S2, 3) control the slope of the integration phase. A change over switch (S1) operates according to two-ramp converter practice.

Title: Ski safety binding with hooks - has adjustable elasticity restraining tendency of skier to topple in any direction
Inventor: WELZEL GERHARD DR
IPC: A63C9/08
Filed: 1977-11-08
Abstract: The ski safety binding prevents the skier from toppling over. The binding has a bridge which is held by a hook connection on components held on skis. The bridge has moving hook features held on fixed parts on the ski. This safety binding elasticity can be adjusted so that the binding can have very long extension, which ensures a reduction of inpact forces. This binding has good centering and the friction in the system provides a clamping effect.
Patent DE-2804131-A1 (DE)
Title: Electromagnetic fluid flow meter - has spaced electrodes in contact with fluid, with adjacent electromagnet to produce electrode voltage according to flow
Inventor: GARDNER WILLIAM L
IPC: G01F1/58
Filed: 1978-01-31
Abstract: A pair of spaced electrodes in contact with the fluid are mounted along a line perpendicular to the fluid flow. An elongated electromagnet provides magnetic lines of force perpendicular to both the fluid flow and the line of the electrodes. This generates an electrical potential between the electrodes proportional to the fluid velocity. The electrode leads are oriented w.r.t. to the electromagnet to minimise the quadrature voltage and the electromagnet is bifilar wound and used in a push-pull alternating current driving circuit. The electrode signals are applied to a synchronous detector to generate a direct current voltage proportional to the fluid velocity.

Patent DE-2806943-A1 (DE)
Inventor: BESSON RENE
IPC: G04G5/02
Filed: 1978-02-15
Abstract: An electro-mechanical watch for advancing the uncorrected watch indicating members to their correct time indicating positions, after a correction period during which one of the indicating members is adjusted and the advancement of the uncorrected members is interrupted. In regular operation, a pulsed signal at a normal frequency from a watch frequency divider drives a stepping motor to advance the indicating members. At the beginning of the correction period, the pulsed signal is switched from the stepping motor to a pulse counter which counts the pulses occurring during the correction period. After the correction period, the pulsed signal is switched back to the stepping motor and a number of signal pulses at a higher than normal frequency, equal to the count of the pulse counter are applied to the stepping motor to advance rapidly the uncorrected indicating members to their correct time indicating positions.

Filed: 1978-02-22
Abstract: Reaction prods. from block copolymers of formula RO(CH2CH2O)X-(CH2(CH3)CHO)y-(CH2CH2O)x-R (I) (where R is x is 50-250; y is 20-100; x:y is 6.5:1 to 1:15), with cpds. contg. >=4 basic NH gps., in wt. ratio 0.8-30:1, or with ethylene imine in wt. ratio 1:0.1-0.8, in polar solvent at 20-180 degrees C, are used as release agents. Used for applying to hot moulds and processing equipment, e.g. for mixing, calendering, etc., esp. for thermoplastics and rubber, and film, sheet, etc. Excellent release is obtd. without affecting adhesion of subsequent coatings. Blocking of plastics or rubber sheet in roll form during storage is prevented. In dil. aq. systems they give high viscosity, which increases with rising temp. stabilising the vapour cushion which forms on the surface of hot moulds and prevents adhesion.

Title: Mine dust concentration moistening - involves sprinkling positively charged dust particles with negatively charged water drops
Inventor: HOELTER HEINZ ING GRAD
IPC: E21C35/22
Filed: 1978-11-25
Abstract: For use esp., in underground mining, where coal cutting points are normally sprayed, so that dust clouds can settle, the process is for moistening quantities of dust with water. Positively loaded dust particles are sprinkled with negatively loaded drops of water, for dust binding; or these factors may be reversed. Equipment pref. comprises a nozzle which generates negative charging of the moistening water with positively loaded dust. It may be partially or wholly made of plastic. This ensures that fine particles of dust are effectively moistened.

Patent DE-2900443-A1 (DE)
Title: Winning electricity by using air as charge carriers - planting pine trees in containers on supports insulated from earth and harnessing built-up charges on needle tips
Inventor: SCHNEIDER JOSEF
IPC: H05F7/00
Filed: 1979-01-08
Abstract: An electricity generating system uses air as the charge carrier. The electricity is derived from the millions of tips of the needles of pine trees which normally discharge to produce ozone. The pine trees are planted in flat bridge-shaped containers supported on columns and filled with earth. The support columns are made from electrically-insulated materials such as ceramic or glass. This prevents the charges built up on the tips of the needles from discharging to earth. The intrinsic charges in the trees will then be harnessed.

In this section the latter has an eccentric shape, providing a sealing pressure for the cap against a peripheral section of the housing inner wall. In another section this inner wall has a larger spacing from the chamber outer wall than the cap thickness. The outer wall is rotatable about its long axis.

Title: Electrical simulation of mechanically loaded structures - has current source and resistor network which allows static performance of loaded beams to be simulated
Inventor: BEHLEN HORST ING GRAD
IPC: G06G7/68
Filed: 1979-06-28
Abstract: An electrical circuit simulation is used to predict the behaviour of beams subjected to mechanical loading. For a cantilever with uniformly distributed load the bending moment (M) and shear force distribution (F) are the integrals of qx. dx and q.dx respectively, where x is the distance along the beam. The cantilever static performance is simulated by current sources, I(0) to I(n-1) with series resistors (R) sized to give the equivalent loading. The technique is applicable to a range of beam configurations.

Title: Filter for combustible dusts - having nitrogen reverse jet cleaning and pneumatic conveying to remove accumulated dust to avoid dust explosions
Inventor: HOELTER HEINZ ING GRAD
IPC: B01D46/00
Filed: 1979-08-31
Abstract: Dust explosions in filter associated with grinders for combustible materials has a draw off system for the collected dust which contains no moving parts which could create friction. This avoids the ignition of the dust. The filter cloth elements are cleaned by reverse jet pulse using N2. This also suppresses the tendency to cause ignition. The filter is for use on grinding plants operating with combustible material. The precautions described avoid or reduce the risk of dust explosion by eliminating points at which ignition could occur.

Patent DE-2944588-A1 (DE)
Title: Machine safety beam gate formed by light barriers - has light sources cyclically energised to send measuring pulse followed by lower powered control pulse
Inventor: BECHTEL KLAUS
IPC: F16P3/14
Filed: 1979-11-05
Abstract: The safety beam gate releases an alarm signal when there is an undesirable intrusion in the working space of a machine e.g a press. The signal causes the machine to be switched off. Light sources and receivers connected to a current supply form several light barriers. An electronic control and evaluator arrangement cyclically switches the light sources and conducts the light receiver impulses related to the transmitted pulses to the evaluator. The evaluator only delivers an output signal when it has received a signal from each light receiver at the end of each cycle. The light sources are sequentially energised from the current supply so that they send a large measuring pulse followed by a lower powered control pulse. The amplified receiver signals are conducted to the evaluator via threshold switches which only switch through when this threshold value is attained.
