Title: Bell-crank arrangement on weighbridge for road vehicles - with force transmitted by load levers to horizontal shackle lines
Inventor: KASBERGER PETER ING GRAD
IPC: G01G19/02
Filed: 1974-09-07
Abstract: A roadway plate has a bell-crank station. A shackle line leads to a guide station and shackel lines lead to a weighing mechanism. The bell cranks are positioned horizontally in the bell-crank station. They transmit to the weighing mechanism the forces in this plane which come from the guide station along the shackle line. In the guide station the load which is applied to the roadway plate produces forces acting in a vertical direction which are guided into becoming forces acting horizontally. The load is applied by load levers from the support plate.

Title: Apparatus for transmitting BCH coded data - uses two separate data correction networks with registers and buffer stores
Inventor: MATT HANS JUERGEN DIPL ING
IPC: H04N19/89
Filed: 1974-09-24
Abstract: The apparatus is used for transmission of data using the Bose-Chaudhure-Hocquenghem (BCH) code, which is a cyclic code with redundances which enable the correction of errors. At the receiver the code blocks are fed into a first correction network, which sorts them to produce collections of errors which may be corrected. The data is then fed into a second correction network in which statistically divided errors are tested. The corrections are produced in correct priority. If the first correction network produces no collections of errors capable of being corrected, the second correction network still operates. The second correction network corrects the results of the first. Registers and buffer stores are used for storing the (BCH) coded data.

Title: Underground coal gasification - with seam divided into panels with separate extraction of gasification gases and carbonization gases
Inventor: HIPPEL HANS-JOACHIM VON DR ING
IPC: E21B43/243
Filed: 1974-10-19
Abstract: A system for the underground gasification of a coal seam in situ sustains the combustion by a gasification medium, rich in oxygen, which is piped below ground from the surface. The gasification gases produced in the gasification areas are kept separate from the carbonisation gases produced in the carbonisation gases produced in the carbonisation areas by the effect of the hot gasification gases. They are either exhausted through separate boreholes and shafts to the surface or they are mixed in a certain ratio, controlled automatically by the pressure ratios in the exhaust systems. This system can be so controlled that a predetermined constant calorific value of adequate magnitude can be maintained in the exhausted gas. No complicated apparatus is required.

Title: Fin mechanically stripped from large blow moulding esp barrel - by knife guided along one arm of holding tongs
Inventor: CERANSKY RUDOLF
IPC: B29C49/72
Filed: 1975-02-07
Abstract: A devce for separating the fin or flash from the base of a large plastics blow moulding opens, the blow moulding is removed by a clamp gripping the fin projecting upwards from the base of the inverted barrel. Beneath this clamp is a pair tongs which grips the fin and takes over the barrel from the clamp; one arm of this pair of tongs comprises a guide, esp. a T-shaped groove, along which the cutting tool is positively guided as it travels across the base of the barrel to cut the fin from the base seam, soi that the barrel can fall freely to a collecting point.
