Title: Gas prodn. from organic materials - by pyrolysis in multiple-grate shaft furnace
Inventor: BALSTER HUGO DIPL PHYS DR
IPC: B01J8/12
Filed: 1979-07-26
Abstract: Gasification of organic materials (e.g. sewage sludge, processed refuse, straw, chaff or whole crops) is effected by pyrolysis in a shaft furnace. The material is moved downwards through the furnace over a series of grates and is gradually heated to the pyrolysis temp. by means of a heat source at the bottom of the furnace. Gas is withdrawn from the top of the furnace and ash is withdrawn from the bottom. The process is simpler than fluidised-bed pyrolysis (cf.DE 2601322) and provides more efficient gas-solid heat- exchange than the use of a rotary furnace (cf. DE 2432504).

Title: Infinitely variable speed drive for gun-laying - uses two electric motors driving gun and outer wheels of planetary gear
Inventor: PETER KLAUS-JUERGEN
IPC: F41A27/28
Filed: 1979-09-28
Abstract: The sun wheel of a planetary gear is driven at constant speed by an electric motor (M1). The outer wheel is driven, via a reduction gear, by a second electric motor (M2). Output is taken from the planet wheel carrier. Gear ratios are chosen so that, with both motors running at the same speed, the output shaft is stationary. Varying the speed of the second motor turns the output shaft forwards or backwards at a speed proportional to the difference of the two motor speeds. This mechanism is used for an infinitely variable speed drive for gunlaying. Both motors have speed control circuits responding to the outputs of comparator circuits. The constant speed motor has a tacho-generator whose output is compared with a fixed reference. The output from an angle encoder on the output shaft is cop compared with an aiming signal to control the variable speed motor. The aiming signal may come from fire control equipment or from a manual control.

Title: Solar collector system integrated in roof - has collector cells or pipe work in each tile joining up when fitted on roof truss
Inventor: HARINK WILFRIED ING GRAD
IPC: E04D13/18
Filed: 1979-12-21
Abstract: A pipe system is inserted in roofing slates shaped as desired to exploit heat from the sun, both directly and from hot air. This arrangement is cheap since tiles have to be brought in any case. It is effective since roofing covers a large surface area and is directly exposed to the sun's radiation and ambient air. No extra unsightly construction is called for. The tiles can be made of clay or concrete and enclose individually small solar collectors or pipe work joined together when the tiles are mounted in position. The tiles can be made with upper and lower parts to enclose the miniature collector or pipe work in sandwich fashion.
