Title: Coke quenching fumes extraction - by swirling air curtains around and above quenching car
Inventor: HOELTER HEINZ
IPC: C10B33/00
Filed: 1973-05-11
Abstract: Thecoke quenching car on the discharge end of coke ovens of the horizontal chamber type is surrounded by air curtains created by nozzles. The quenching fumes are thereby directed towards an extractor cowl for quick removal. The nozzles creating the air curtains above the quenching car are fitted with deflector plates so that the air flow receives a swirling motion. The swirling flow acts as a more effective barrier for the coke quenching fumes; a dust extractor deals with the fumes immediately. Operators in other parts are protected against noxious fumes.

Title: Low inertia humidity meter for flowing gas - has pair of fixed electrodes in surface on which moisture condenses
Inventor: RYBAK BORIS
IPC: G01N27/12
Filed: 1973-06-22
Abstract: The low inertia moisture measurement or control instrument is for checking the humidity of a flowing medium, especially a gas of low electrical conductivity, having a support for a pair of electrodes at a fixed distance apart between which a high resistance exists, which is reduced by the presence of water or water vapour in the medium. The surface between the electrodes may be a smooth surface on which water vapour will condense as a thin film, or evaporate, as the humidity of a flowing gas alters.
Patent DE-2335819-A1 (DE)
Title: Vehicle separation measurement system - has two transmitters and one receiver per vehicle
Inventor: ZENGER ALFONS
IPC: G01S11/06
Filed: 1973-07-13
Abstract: One transmitter points forwards and the other points backwards. The receiver points forwards. A parabolic reflector transmits electromagnetic waves, pref. microwaves in a spherical space along the axis of the vehicle. The receiver measures the distance to the vehicle in front by the field strength. When two vehicles travel towards each other both receive a signal. The signal can give warning to a driver when a certain threshold is reached. Modulation of the signal minimises response to spurious signal sources. The sensitivity of the receiver may be controlled by the speed of the vehicle and weather conditions to increase safety.

Title: Motor vehicle testing track - is in independent sections interlocked to allow movement only when longest operation complete
Inventor: HESPER KARLHEINZ DR ING
IPC: B60S13/00
Filed: 1973-10-27
Abstract: The track is for testing vehicles for fitness to be driven on the road, and the vehicles are indexed through the various testing stations by a transporter mechanism. This is divided into two or more independently drive sections, and all stations have means for l ocking the drive mechanisms, also release switches. The latter are so interconnected with each other and with the locking devices that the vehicle on the track can only be indexed forward after completion of the longest necessary individual testing period. A computer can be used to control the individual tests, supply the stations with figures representing the desired values, and record and evaluate the test results. These latter can be delivered to the computer as measurements obtained, or in the case of a visual or functional check from push-button control panels.
Patent DE-2361053-A1 (DE)
Title: Liquid supported borehole walls - have sheet plastics seal positioned by guide shoe or weights
Inventor: JESCHOR HELMUT DIPL ING
IPC: E02D5/18
Filed: 1973-12-07
Abstract: The borehole walls are lined with sealing plastics sheets in order to prevent loss of liquid and the walls are stabilised by hydraulic pressure against the pressure of the ground water level. The sealing arrangement saves thixotropic liquid in the ground and reduces the friction forces when pipes or piles are inserted. The profiling cylinder is pushed into the borehole and it positions the plastics sheet so that the latter passes from the top of the cylinder, through the cylinder bore and around the base shoe and against the borehole walls. The space between the cylinder and hole lining is filled with water. The central bore is also filled with water for removal of the cylinder. The annular space is emptied and filled with concrete.

Title: Filler cap with tightening torque limiter - has loose ball mechanism with spring loaded wedge ring between cap parts
Inventor: REUTTER HEINRICH
IPC: B60K15/04
Filed: 1974-01-23
Abstract: The closing cap is used for a motor vehicle fuel tank and the tightening torque limiter prevents damage due to excessive tightening. When excessive torque is applied then only the actuating part rotates and the screw neck remains stationary. The screw cap has a screw section with a thread and the actuating cap. The actuating cap and the screw section have pockets which accommodate a loose connecting element in the form of a ball. One of these components has a sloping face which assists in disconnecting the tightening torque drive between the two components. The actuating top cap is held against the screwed section by a truncated conical helical spring which provides axial load on the ball connection.

Title: Heel rest for car foot controls - with replaceable raised non-slip pad floor mounted behind pedals
Inventor: THEIS HERMANN
IPC: B60N3/06
Filed: 1974-02-14
Abstract: The heel rest comprises a circular pad with a domed profile which is fitted to the floor behind the pedals. The driver rests his heel on the pad and by twisting his foot, he can reach the different pedals. The pad is glued or riveted to the floor and is replaceable. It is made from plastic or non-slip coated metal. The pad prevents build up of grit under the heel, and protects the heels from wear and tear. The pad also is slightly resilient to provide a more comfortable resting point for the foot.

Title: Ski safety binding with asymmetrical action - engaged with little effort but then holding strongly against minor shocks
Inventor: SITTMANN GEB VOESTER BRIGITTE
IPC: A63C9/08
Filed: 1974-04-02
Abstract: Resistance, supplementary to the effect of a comparatively light spring, is offered to the opening of the clip; no such resistance is offered to its closing. Many alternative versions of this idea are worked out. In one the resistance is frictional, applied or not according to the direction of rotation of a freewheel; other versions position the freewheel differently, or use an oil dashpot with one-way pressure-release valve, etc., etc. Each is first worked out for a heel catch and then used also for a toe catch consisting of a pair of the heel catches laid on their sides and facing inwards.

Title: Tape recording system - compression characteristics of recording, expansion characteristics of reading ccts. compensate for noise, demagnetisation
Inventor: SZOKOLAI ZOLTAN
IPC: H03G9/02
Filed: 1974-05-31
Abstract: A tape recording system in which the noise and demagnetisation characteristics are improved, using "Dolby B" techniques, includes feeding the signal to an amplifier with a transfer function carefully shaped to suit the recording medium, for example so that considerable pre-emphasis at higher frequencies is provided. The output of this amplifier is fed to a dynamic compressor unit which again has a carefully shaped amplitude frequency dependent transfer function so that the output range of amplitude and frequency is smaller than the input range. The output of this is fed to a linear amplifier and recorded via a suitable writing head on the magnetic tape. A reciprocal arrangement of amplitude and frequency dependent units is used in the reading circuitry, one unit being an expander which re-establishes the original range of amplitudes and frequencies.
