Patent DE-2537764-A1 (DE)
Inventor: STAENDER HERMANN DIPL ING
IPC: B24B17/02
Filed: 1975-08-25
Abstract: The presetting of a workpiece slide (11) can be determined by a template (21), the template being attached together with the workpiece to the movable workpiece slide (11). The template (21) bears with elastic pretension against an adjustable template stop (42). The initial and end positions of the working stroke of the workpiece slide (11) can be set as a function of a regulating device which is connected to the template stop (42). The regulating device advantageously has a control member connected to a regulating cylinder. The initial and end positions can preferably be determined by adjustable stops. The control member can be of wedge-shaped design. It is thus possible to reduce the working movements of the workpiece slide and to achieve the highest degree of repetitive accuracy. <IMAGE>

Title: Retort pyrolysis of oil shale - using heat from combustion of residual coke under conditions giving low sulphur emission
Inventor: DEERING ROLAND FRANK
IPC: C10G1/02
Filed: 1976-10-29
Abstract: Continuous retort pyrolysis of oil shale, in which the residual shale contg. alkaline minerals, coke and sulphur cpds. is passed with an oxygen-contg. gas stream to a combustion zone. At least part of the coke is burnt, and the amt. and temp. of the gas supply are controlled to cause reaction of the gaseous S cpds. formed (e.g. SO2) with the alkaline minerals, and give an oxygen-contg. exhaust gas substantially free from S cpds. Pref. almost all the coke is burnt, with combustion zone temp. of 482-910 degrees (760-871 degrees)C. Total gaseous S cpds. in the exhaust gas are below 100 ppm., with 5 SCF max. per tonne shale, and H2S content is below 5ppm. Passage of shale residue and gas through the combustion zone in the same direction gives better control of temp. and reduces pressure drop due to collection of fine material. Max. heat energy is recovered by combustion of virtually all the coke, for use in the process or conversion into energy. Prod. gas from the shale pyrolysis is partly heated and re-circulated as heating medium, but not consumed for heating purposes.

Title: Connection between electrical component and printed circuit board - by folding wires back to form radially-acting spring contacts to through plated hole
Inventor: THOM GUENTER
IPC: H05K3/30
Filed: 1977-09-22
Abstract: The electronic component's wires are connected to a printed circuit board simply by looping the ends of the wires back on themselves to make a kind of spring that presses outwards against the conducting inside of the hole in the board. Instead of being folded back on itself, the wire may be looped in a vertical plane, coiled in a horizontal plane (helix) or just have a kink set into it. In all cases the wire's deformation behaves as a contact spring acting radially.
