Abstract: Removal of SO2 and other harmful matter from flue gas is effected by scrubbing with a liquor contg. ca(OH)2 and opt. CaO, sepg. the insol. Ca cpds. and recycling the liquor, after adding Ca(OH)2 and/or CaO if necessary. The improvements are that SO2 and other harmful matter are removed from pt. of the flue gas using powdered CaO and/or Ca(OH)2 as sorbent and both gas purified gas fractions are combined before discharge to the atmos., whilst (pt. of) the sorbent used for dry purificn. is added to the wash liquor used in wet purificn. Pref. the flue gas fractions are purified before entering a chimney. The dry sorbent is circulated and fresh sorbent is added. Spent sorbent is removed and crushed and pref. slaked before adding to the wash liquor circulation. The spent sorbent is introduced into the furnace. The combined gas stream has a dew point above that of corrosive matter still remaining in the flue gas, preventing damage to the discharge channels and chimney and avoiding the need to heat the purified flue gas from the wet purificn. stage.

Title: Device for lowering the temperature of thermostatically controlled heating bodies
Inventor: GANZ PETER DIPL PHYS DR
IPC: G05D23/32
Filed: 1981-03-16
Abstract: The invention serves for lowering the temperature of individual heating bodies, which have to be equipped with thermostatic valves, for a time preprogrammable as desired. It thereby becomes possible to heat the individual rooms of a house only at the times when these are normally used. A considerable saving of heating energy can be achieved as a result. The invention consists of a programmable timeswitch, by means of which an electrical heating system is switched on and off. The device is fastened under the thermostatic valve of a heating body and heats the air in the vicinity of the temperature sensor for the time during which the room temperature is to be lowered. The valve reacts to the rise in temperature by throttling the supply of energy of the heating body, with the result that the room temperature drops.

Title: Liquid-cooled electric subassembly, and method for producing it
Inventor: BERIGER CONRAD DIPL ING
IPC: H01L23/473
Filed: 1981-04-10
Abstract: In subassemblies having components through which electric current flows, there is the problem of dissipating heat in a pinpointed and highly efficient manner. For this purpose, a cooling element (7) is fitted with a spiral coolant line (20-24), which is located as near as possible to at least one surface (25, 26). The spiral shape of the coolant line (20-24) is particularly suitable, since in most active semiconductor elements heat is to be dissipated by a circular surface. A method for producing cooling elements is suitable, in particular for mass production on a pressure die-casting machine. In this process, the coolant line is positioned during the actual casting process by means of supports (15) and a controllable core (16a). <IMAGE>

Title: Wireless and proportional control for toy vehicles
Inventor: ZINN PETER
IPC: A63H30/04
Filed: 1981-04-16
Abstract: Wireless and proportional control for toy vehicles permits realistic steering of toy vehicles with electromechanical drive. Furthermore, the drive motor is started up via the control. Ultrasonic pulses which are output by a transmitter component (Figure 1) serve as transmission means. The duration of the pulses is influenced with R2. In a receiver component (Figure 2), the ultrasonic pulses are converted into direct voltage pulses which drive the servomotor (M1). Thus, the speed of revolution of the servomotor can be controlled in a wireless fashion. A structure whose actuator travel is dependent on the speed of revolution of the servomotor is used as servo. The drive motor is switched on by the direct voltage pulses acquired from the ultrasonic pulses charging a capacitor (C12 on Figure 2) and the direct voltage present at C12 being fed, after amplification, to the drive motor (M2). <IMAGE>
