Title: AC series motor speed control system - uses feedback signal dependent on motor power factor
Inventor: BRESSERS CORNELIS GERARDUS
IPC: H02P25/14
Filed: 1976-11-03
Abstract: The object is to give stable speed of the motor shaft between no load and full load for any preset value of speed. Control is by means of a thyristor (7) in series with motor (M) and the supply. The instant of triggering is determined by the charge on a capacitor (c2) as set by a variable resistor (R2). An additional RC circuit and diode (R1, C1, D1) across the motor produces a charge on the capacitor (C1) which is dependant on the relative phase of motor current and voltage. This charge is added to that on the main triggering capacitor (C2). Variation of motor power factor between no load and full load thus varies the trigger point of the thyristor and assists in keeping the speed approx. constant over the designed range.

Title: Methane prodn. by coal hydrogasification - with hydrogen produced by methane cracking in furnace heated by char
Inventor: JAEGER WALTER ING GRAD
IPC: C10J3/00
Filed: 1977-02-03
Abstract: In a plant for the hydrogasification of coal, part of the CH4 produced in converted to H2 and CO in a cracking furnace heated by means of the heat generated by burning the char from the hydrogasification reactor. Using the char to heat the cracking furnace (and thus produce the H2 required for hydrogasification) is stated to be more economic than reacting it with steam to generate an H2-rich gas (cf. Chem. Engrg., 59-61, 1971). The char can be passed directly to the cracking furnace as fuel, or it can be reacted with steam and air to produce a lean gas which in turn is used to heat the cracking furnace.
