Title: All glass door wing ironmongery - has asymmetrical screw hole in flap turned for selective engagement with plate
Inventor: BAUM HANS DIPL PHYS DR
IPC: E05D7/04
Filed: 1978-11-30
Abstract: The ironmongery fitting for a door entirely made of glass comprises a plate, on one side of the wing, carrying the pivot bearing, and a fixing flap on the other side, clamped to the plate by screws passing through holes in the wing. The plate (1) has two or more holes (9-12) sited symmetrically to the centre axis (X-X), and the flap (15) has at least one hole (16-17) asymmetrical to the centre axis (Y-Y).

Title: Damage elimination in ceramic wall and floor lining - involves injecting liq. substance into cavities through surface holes until overflow occurs
Inventor: RUNDMUND THEO
IPC: E04G23/02
Filed: 1978-12-18
Abstract: The process for checking and repairing fissures and other damage in ceramic wall and floor lining is esp. applicable to external wall facades, swimming-pools, sewage treatment plants and floors of rooms subjected to moisture. A liquid substance, pref. a low-viscosity neutral substance is injected into hollow spaces in the sub-structure (2), joints (11) and tiles or panels (1), via holes (12) distributed over the surface. This is done until an overflow emerges through surface pores and fissures. For repairs, hard-setting, acid-resistant mortar or plastics, are injected, and emerging overflow is wiped away. The process provides good economy, with min. dust and noise involved.

Title: Degassing tower for boiler feed water - where water is sprayed into steam for removal of corrosive gases such as oxygen and carbon di:oxide
Inventor: JANSEN ERNST DIPL ING
IPC: B01D19/00
Filed: 1979-02-21
Abstract: A vertical tower contg. no inserts or filling is fitted at its upper end with a pipe contg. rows of outlet nozzles for water driven into the pipe by a pump. The water is converted into fine droplets by the nozzles, and the droplets are evaporated by steam fed into the tower. The result is that corrosive gases, e.g. O2 and CO2, present in the water enter the steam and are removed with the steam via a top exit in the tower. In the pref. plant, the pump circulates the water through the nozzles and tower via a network of pipes fitted with a second, independent pump employed to feed the treated water to a boiler, so the water travels several times through the nozzles. The top gas exit in the tower is pref. fitted with a filter minimising the amt. of steam used to carry the corrosive gases out of the tower.

Title: Driving simulating amusement assembly - disconnects drive to vehicle symbol carrying belts, when manually controlled symbol impinges on it
Inventor: WATANABE HIROYUKI
IPC: A63F3/00
Filed: 1979-03-16
Abstract: The amusement device has movable belts (256-260) representing road lanes and a central line. The lane belts hav e vehicle symbols thereon (480). A steering wheel (40) controls lateral movement of a further vehicle symbol (426).

Title: Electronic module encapsulation - in expanded epoxy! resin for good mechanical and electrical strength
Inventor: HUSSAIN AMIR DR
IPC: H01B3/40
Filed: 1979-06-21
Abstract: Electronic components and modules are insulated by totally enclosing them in expanded epoxy resin. In the case of capacitors, specially good results have been obtained from the following RTM materials: resin XB2972A, hardener XB2972B, Frigen 11 as the blowing agent. This has not the detrimental effect of polyurethane foam which causes corrosion by carbon dioxide. Epoxy foam for self-healing capacitors results in a capacitance drift of 1.3% over 1000 h, compared with 12% for a polypropylene insulation. It combines good mechanical and electrical strength.

Patent DE-3030594-A1 (DE)
Inventor: KUHLOW JUERGEN DIPL ING
IPC: B61F3/04
Filed: 1980-08-11
Abstract: In a propulsion unit for the driven axles of an electrically-powered rail vehicle, the torque of an electric propulsion motor is transmitted to the respective driven axle by way of a torque transmitting mechanism including gears and couplings. A common housing in the form of a hollow beam is used to enclose the propulsion motor, a bearing system, and a transmission. Cut-outs are provided in the sides of the housing to allow space for the driven axles. In order to increase the flexural and torsional stiffness of the propulsion unit, the hollow beam includes an annular end surface through which the propulsion motor and torque transmitting apparatus are inserted. The hollow beam not only forms a common housing or the propulsion components, but is a very stiff support element that reduces vibration and improves the running behavior of the propulsion unit.
Patent DE-3034874-A1 (DE)
Inventor: ECKLI PAUL
IPC: A61M5/36
Filed: 1980-09-16
Abstract: By optoelectric scanning of the infusion hose in a desired position near the body, and by just such scanning of the contents of the line by means of a downstream time differential detector, as well as by disjunctive superimposition of the corresponding error signals, monitoring of the infusion current for air inclusions with high reliability is achieved. The monitoring circuit with scanning channel (AK) and associated transmitter (S) and receiver (E) is accommodated in an infusion hose clamp (LH) which can conveniently be arranged in the vicinity of the location where the infusion enters the body, and therefore enables the flow system to be monitored for air inclusions up to the inlet position. A further improved reliability of monitoring is achieved by storing the error signals and providing reconnection which is locked against the continued existence of an error signal. <IMAGE>
