Title: Lever type of car jack - with eccentric lever hinged under car and operated by moving car
Inventor: PRANKL RUDOLF
IPC: B60S9/02
Filed: 1975-09-22
Abstract: Thec ar jack is replaced by a simple support level with eccentric stub axles. One of these is slotted into the jacking point under the chassis and car moved forward. The lever drops to the ground and raises the car. It is released by a Bowden cable from inside the car. The lever can be in the form of a plate with its lowest edge lower than the bottom part of the wheels. In order to raise the car on rough ground, the drive wheel on the lifted side can be blocked using simple wedges. The lifting lever is simple to operate without any manual effort. It has no moving parts to corrode.

Title: Component recognition by industrial robots - determines angular position of component by scanning for centre of area and determining dia. of circle tangential to profile
Inventor: GEISSELMANN HERIBERT DIPL PHYS
IPC: G01B11/03
Filed: 1975-11-26
Abstract: The optical sensing system for component identification allows angular position to be determined. A television camera scans the component and from the data obtained the centre of area is determined. A second stage involves the determination of the diameter of a number of circles tangential to the profile surfaces of the component. The component is scanned a second time with reference to the calculated centre of area to determine the co-ordinate position of a boundary contact with one of the reference circles. From the co-ordinate data the angular position is calculated.

Title: Low temp. coke and high quality gas prodn. - by final heating of coke from fluidized bed low temperature oven
Inventor: HAMEIER MARTIN
IPC: C10B49/10
Filed: 1975-11-29
Abstract: Low-temp. coke is produced by keeping dried and preheated coal in a low-temp. oven in a fluidised bed. The extracted coke is heated in a final heater to a temp. above that of the oven and is sepd. in cyclones from the produced gas. The waste gases from the final heating operation are used as heating medium in the preheater. The fluidising medium in the oven is carbonisation gas from the process which has passed through a waste heat recovery and after-combustion stage. This is a continuous process, which combines the yield of L. T. coke with L. T. gas of high calorific value (above 5000 kcal/m3) and a max. tar yield.

Patent DE-2558496-A1 (DE)
Inventor: YASUDA KAZUMASA
IPC: G04B19/253
Filed: 1975-12-24
Abstract: A winding stem mechanism including a winding shaft having a detent portion comprised of a pair of annular peripheral recesses with an annular step portion therebetween, and a pair of annular stops each adjacent a respective one of the recesses, and mounted for rotation and for being axially slidable. A resilient spring-like member normally engages a first of the recesses to define a normal position of the shaft and when the shaft travels in a first axial direction the spring-like member climbs the annular step portion to engage the second of the recesses. When the shaft travels in a second axial direction it pushes the annular stop adjacent the first recess to flex the spring-like member to permit the shaft to travel to a second operating position and flex in a direction effective to bias the shaft back from the second operating position to the normal position when the shaft is released.

Title: Dynamic machine drive mechanism - has pairs of eccentric weights with their centre of gravity following restricted path
Inventor: POISEL OTTO KARL DIPL ING
IPC: F03G3/00
Filed: 1976-03-13
Abstract: The machine has a casing (13) with a drive from an electric motor (5) at each end. Within the casing is a pair of weights (1, 2) between securing elements (7). The weights are moved by the motors through drive linkages (4). The centre part of the casing contains two cylindrical cams (8) which guide the motion of the weights in a determined pattern. This is such as to ensure that the centre of gravity of the pair follows a path which lies within one half of a circle. The out of balance forces result in linear movement of the machine. The form of the cams and the path of the centre of gravity enable the machine to have a high output without oscillation or noise.

Inlet and outlet ports are so arranged relative to the elements that the strips only move radially in the neutral pressure zones, where they are not exposed to differential pressure.
Patent DE-2630754-A1 (DE)
Title: Exposure process for X:ray roll film - uses alternate viewing settings at end of film nearest to next unexposed frame
Inventor: FISCHER FREDI DR MED
IPC: G03B42/02
Filed: 1976-07-08
Abstract: The roll film X-ray equipment has a special film transport control which splits the film into set sequences of exposures. The film is reciprocally transported between exposures so that direct view checks can be made on the image converter screen during the exposure sequence. After each exposure the film is transported to a set frame while the direct view is used. When a set number of frames has been exposed, the film film is transported forwards to the end of the next set of frames, where a blank frame is used for each direct viewing operation. A minimal number of frames is thus wasted so that a maximum number of exposures is obtained on each roll of film. Fast moving sequences of X-ray pictures can then be achieved.

Title: Continuous mixer including vertical vessel - with inner and outer chambers for main and secondary components
Inventor: HERFELD FRIEDRICH WALTER ADOLF
IPC: B01F15/00
Filed: 1976-08-09
Abstract: Continuous mixer comprises a vertical-axis mixing vessel with a central agitator shaft bearing vanes at the bottom. The vessel is divided by a concentric ring wall into an inner chamber for holding the main component in batches, and an outer chamber for continuously adding secondary components, for mixing and for discharge of the finished mixture. The vanes bear a rotor ring which is opposite the ring wall and which with the lower edge of the ring wall defines an annular gap. At the lower edge of the ring wall and/or on the rotor ring is a comb-like structure extending over the opening of the annular gap, pref. in the form of a ring of pins. The gap prevents insufficiently comminuted particles from entering the outer chamber, and can restrict the dimensions of the granules in one direction only.
