Title: Synthetic natural gas prodn. from brown coal - using tubular gasifier and methane producer with waste heat recovery
Inventor: WENZEL WERNER PROF DR ING
IPC: C07C1/00
Filed: 1973-06-13
Abstract: Synthetic gas reasembled natural gas is produced from crude brown coal by gasification in horizontal or slightly inclined tube furnaces with two gasification sections, held at different temps. The CO produced is converted to obtain H2/CO, ratio of 3:1 and the CO2 is then removed from the converted gas. The following methanization is accompanied by waste heat recovery fro heating the first gasification section of the tube furnace. The residual coke is used to mfr. producer gas which is added to the tube furnace outflow. Recovery of the heat resulting from ethanization covers 40% of the total heat requirements. This reduces the mfg costs and makes the synthetic gas competitive with natural gas.

Title: Drive mech. for sliding windows or door pressed against frame for seal - has lever actuated fork shaped actuator with guide element
Inventor: STRAUB THEODOR
IPC: E05D15/10
Filed: 1973-08-13
Abstract: The panel can be pressed against the fixed frame in any required sliding position of the window or door. The transverse movement to the panel frame is imparted by a swivelling fork member. This member grips by its jaws the edge of the frame to be actuated. The fork swivels about its pivot and the fork itself is actuated by the sliding member which has a sloping groove and the walls of this groove impart lateral movement to the fork. The arrangement is actuated by a actuating rod system within the sliding frame. A comparatively simple mechanical construction is achieved.

Title: Deep drawing plastics sheet for automobile mouldings - using hinged frame to stretch sheet to shape of hollow pattern
Inventor: BREITLING ROLF DIPL ING
IPC: B29C51/26
Filed: 1974-04-17
Abstract: Stepwise, continuous deep drawing of a plastics sheet held in a frame by vacuum forming gives articles having a concave or similar surface; the moulding being used later as a stiff shell to be backed by a foam plastics layer. The supporting frame for the sheet has hinges at the positions corresp. to the hollow region of the pattern; the hinges are used to enable the supporting frame to be depressed to correspond approx. to the surface shape of the pattern. When heating to 150 degrees C is used for the sheet, the hinges are pref. carried on a pair of rails, and the pattern is pulled in below them after the sheet has been heated; the ends of the frame are then raised, esp. using piston-cylinder units, and vacuum is finally applied to pull the sheet down onto the pattern. Subsequent deforming of the sheet to the curved or hollow pattern is considerably reduced, giving a much better prodt., esp. for dashboards, transmission housings, etc., for cars.

Title: Excitation cct for brushless sync motor - has single auxiliary thyristor controlling main rectifier thyristor firing
Inventor: SCHICHT WERNER DIPL ING
IPC: H02P25/03
