Abstract: Car jack, in whose upright housing, which has a longitudinal slot for the lifting bar, is a lifting spindle, whose top end carries a gear, e.g. a crown gear, above the bearing point within a bore of a U-shaped head piece, while holes in the two side walls of the U-head piece support the horizontal section of a drive crank, to which is coupled a drive gear, which acts with the crown gear, and which can move axially in the direction of rotation. The gear chamber of the head piece is releasably closed at its open end by a U-shaped cap. In its middle region, the cap is fixed to the inside of the cap middle wall and a long, cradle is fixed to two cap side walls, which on fixing, grips around the cap from above to fix the covered section of the shaft such that on pressure or impact on the cap middle wall, the diameter of the cradle grips over the shaft to locate it.
Patent DE-2406292-A1 (DE)
Title: Magnetic tape with optically-read marks on back - corresponding at extremities to smallest and largest number input through keyboard
Inventor: SCHOLZ WERNER DIPL ING
IPC: G11B15/08
Filed: 1974-02-09
Abstract: Optically-read markings on the backs of magnetic tapes are used to permit the tape recorder user to find a particular position on the tape by in-putting a number through a keyboard. The markings in the form of long and short bars are read by converters which emit impulses, these being compated with the keyboard input in an evaluator. The latter is designed to stop tape movement when scanning of the tape markings show that it is running in the wrong direction. The tape has at the beginning and end of the scanning tracks binary markings equivalent to the smallest e.g. 000 and largest e.g. 999 numbers which can be input through the keyboard. The tape may have both extreme 000/001 and 998/999 values and there may be markings detectable by the evaluator so as to reverse tape movement.
Patent DE-2411559-A1 (DE)
Title: Electronic anti-skid control for car - with speed related impulse generator and impulse counters to monitor successive wheel rotations
Inventor: DICKINSON HARVEY FRANK
IPC: B60T8/175
Filed: 1974-03-11
Abstract: An impulse generator provides a train of impulses with a frequency corresponding to the calculated road speed of the vehicle, and which is much greater than the wheel revolutions. A solid state control/monitor system counts the number of impulses for a set amount of travel of a particular wheel, and stores the result. A second count follows, with the two counts compared w.r.t. road speed etc, to calculate a retardation value of the wheel w.r.t. road speed, and hence the amount of wheel slip. The system uses simple logic circuits and is simple to fit to existing vehicles, and has no moving parts.
Patent DE-2414721-A1 (DE)
Title: Control circuit for linear motor fed by inverter - uses motor thrust as control and reference values for current and frequency control
Inventor: JOHN ANSGAR DIPL ING
IPC: H02P23/08
Filed: 1974-03-27
Abstract: In all operation modes the desired motor thrust is the controlling value and sets the required value of motor current. The actual motor current is controlled by the regulating section. In the lower speed range, tht is when the inverter output voltage is less than maximum, the motor current is controlled by output voltage variation. When the output voltage reaches maximum, that is in the higher speed range, control of the thrust is performed by slip frequency variation. The inverter voltage and frequency output are controlled by the actual speed signal and the required slip frequency value.

Title: Resiliently coated rod for potato harvester separator-belt - consisting of extruded fingers, is formed by cutting out material between fingers
Inventor: JAEGER ARNOLD
IPC: B65G17/34
Filed: 1974-04-29
Abstract: The extruded section consists of a core enclosed by a hollow cover-piece, and two side-pieces joined to it. The side-pieces have cavities in so that between the cavities are trapezoid fingers. The fingers thus formed from the side-pieces are on the same rotary plane as the separator belt. Alternatively, one row of fingers can be positioned on one side of the other row fingers. Trapezoid or rectangular shaped fingers are suitable for a weed-separator belt, and long, narrow fingers for a stone separator belt. The fingers are preferably made of rubber for its elasticity, and the less elastic polyvinyl chloride or polyethylene for the weed-separator belts.

Title: Roller gate movement stopping mechanism - has sprocket with slight angulaight angular displacement against shaft to move sliding catch against gate frame mounted stop
Inventor: SCHEMITSCH PETER
IPC: E06B9/84

Between the pins (1, 2) a spiral spring (8) is fitted. When the spring (8) becomes operative due to angular relative displacement between the sprocket and shaft, a catch (6) travels towards frame mounted stop (12), where it comes to rest. The stop (12) can be fitted with a switch cutting out the motr when the catch reaches the stop.
Patent DE-2540234-A1 (DE)
Title: Two-channel direction finder - uses automatic balancing of directional signal voltages involving prodn. of sum voltages
Inventor: FLIEGE HANS-JOACHIM DIPL ING
IPC: G01S3/04
Filed: 1975-09-10
Abstract: The phase of one of the directional signal voltages is shifted by 90 deg. w.r.t. the other. One of these voltages is then multiplied in a control circuit by a voltage x and added to the other, so that a first sum voltage is produced. A second voltage is similarly produced from the second directional signal voltage. This x voltage is generated by a product detector from the two sum voltages. When the control circuit is well balanced, phase difference between the first and second sum voltage is 90 deg. and the voltage x is proportional to the imbalance. Two voltages are derived from the two sum voltages by restoring the in-phase state. They contain the undisturbed direction finding signal.

Title: Washer for dusty gases - having liquid injection points integral with venturi gas nozzles
Inventor: ALBRECHT WOLFGANG DR ING
IPC: B01D47/10
Filed: 1976-01-13
Abstract: Hollow elements are arranged on a grid at right angles to the gas stream, and are shaped so that the gas passages between them are venturi-shaped. Holes are formed in these hollow elements at the narrowest point of the gas passages, and wash water entering through the hollow elements sprays into the gas stream from these holes, the high gas velocity breaking the water film up into the very small droplets which have high dust collection capacity. The injection holes in adjacent elements are staggered. A further series of holes may be formed downstream of the first, angled to project the water upstream, and fixed deflector plates may be located between the hollow elements on to which this projected water impinges. Used in washers for the removal of suspended solids or liquids from gas streams. Removal efficiency is improved.

Cosmetic compsns. include creams, sun-tan creams and emulsions, soaps, bath oils, foam baths and lotions. (I) are colourless to light yellow, crystalline or highly viscous, stable, non-toxic prods. and are easily worked into cosmetic emulsions. Tests on dried pigskin showed that addn. of (I) to compsns. can increase water-retention by >=10% at 30% RH, rehydration by >=10% at 90 RH, and elasticity after loading by >=1.8 mm at 90% RH. In an example, a day-cream contained 3% malonic acid bis-ethanolamide.
