IPC: B29B7/76
Filed: 1980-03-12
Abstract: A mixing head for mixing together two or more fluid components, esp. for the mould-foaming of polyurethane, has a long narrow, pref. cylindrical mixing chamber into which nozzles lead transversely from supply ducts. These component supply ducts have their longitudinal axes at an acute angle to the longitudinal axis of the mixing chamber, considered in the discharge direction, and the nozzles lead into the mixing chamber at the point where the supply duct is nearest to the mixing chamber. Pref. the angle between the longitudinal axes of the supply ducts and mixing chamber is less than 45 deg., more specifically approx. 20 deg., and two material supply ducts reach it at the same angle. An internal tube can be axially displaced inside the component supply duct to block the outlet nozzle. Particularly for polyurethane foaming. The apparatus is compact and narrow. In each component supply duct, when the outlet nozzle is blocked, the material can flow back through a recirculating system.

Patent DE-3035588-A1 (DE)
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: H04L1/20
Filed: 1980-09-20
Abstract: The error recognition method, which can be used for all types of modulation, consists in that a plurality of time function elements (A, B, C, D) are started at the start of an edge change. Each time function element is assigned to the tolerance limit of a code. The time function elements are evaluated by means of a register (2) and logic (3). This evaluation makes it possible to recognise whether a time function element has responded within or outside the permitted tolerance limits of the code, or whether the code was correctly transmitted. <IMAGE>

Patent DE-3119340-A1 (DE)
Title: Washing machine with an electrically drivable lye pump
Inventor: HUBER HEINRICH
IPC: D06F39/08
Filed: 1981-05-15
Abstract: This washing machine has a widening in the emptying line downstream of the lye pump, which widening, when the lye pump is running, forms a water store which, after the lye pump has stopped, serves for filling up the emptying system and is intended to prevent the washing agent added in the new programme from passing unused to the emptying system. Furthermore, the washing machine has an emergency overflow which prevents an overfilling of the lye tub and which protects electrical devices of the machine, which are arranged above the emergency-overflow level, from being flooded. To simplify the guidance of liquid, the widening of the emptying line and the emergency overflow are combined to form a constructional unit.

Title: Drive unit for motor vehicles, especially passenger motor vehicles
Inventor: FRIEDMANN OSWALD
IPC: B60K6/10
Filed: 1981-06-05
Abstract: In a drive unit, in which a flywheel, arranged between an internal combustion engine and a manual shift transmission, in certain operating conditions of the motor vehicle can be uncoupled from the engine by means of a clutch arranged between the engine and the flywheel and also from the manual shift transmission by means of a clutch and the engine can be shut off when the flywheel is uncoupled, a further clutch is provided which, when the drive connection between engine and flywheel is separated and the clutch is disengaged, couples the flywheel to the manual shift transmission by way of a drive connection with transmission ratio, so that in overrun conditions of the vehicle the flywheel can be driven by its drive gears. The transmission ratio of the drive connection for the flywheel is at the same time designed in such a way that when recoupling the flywheel to the engine the rotating flywheel has a kinetic energy level which is sufficient to virtually compensate for the difference in speed between the engine and the transmission input shaft, so that maximum comfort is ensured in re-establishing the drive connection between engine and transmission by avoiding unwanted jerks.

IPC: G21C1/07
Filed: 1981-06-13
Abstract: The invention relates to a means for shutting down a high-temperature reactor which is cooled with helium and has a core consisting of spherical fuel elements. This means which permits a probable residual risk to be covered comprises two diverse shut-down systems which are independent of one another. The first shut-down system consists of absorber rods which can be moved into bores of the side reflector and of absorber rods which can be moved into the core and serves for rapid and long-term shut-down and for controlling the reactor. The second shut-down system is only used for long-term shut-downs and is formed by a device with which helium-3 can be fed into the reactor core.

Title: Process and plant for the selective separation of chlorides and fluorides from flue gases or exhaust gases
Inventor: KARGER ROBERT
IPC: D06M13/352
Filed: 1981-06-24
Abstract: Process and plant for the selective separation of chlorides and fluorides, in particular from flue gases or exhaust gases, in which, in a scrubber circulation (1, 4, 5, 6, 7), HCl and HF are virtually completely absorbed and SO3 is partly absorbed by a highly concentrated calcium chloride solution. A portion of the loaded calcium chloride solution is ejected into a secondary circulation (14, 15, 21, 22, 27, 28, 29). The free acids contained therein are neutralised by addition of alkali metal oxides, hydroxides or carbonates and/or alkaline earth metal oxides, hydroxide or carbonates. Only very low amounts of solids (CaSO4.2H2O, CaSO3.1/2 H2O) can form in the scrubber circulation, and only small amounts of waste water highly concentrated in salts are ejected, which can be simply disposed of, for example by spray-drying. <IMAGE>
