Patent DE-4304540-A1 (DE)
Title: Electric connection for heating elements in radiant heaters
Inventor: MORITZ RAINER
IPC: H05B3/74
Filed: 1993-02-11
Abstract: The invention relates to an electric connection for heating elements in radiant heaters, in particular for glass ceramic cooking surfaces. Since the insulating members for the radiant heaters are usually supplied as prefabricated parts, a solution is to be created which permits the complete electric connection of the heating elements to be realised during the final assembly of the radiant heater without having to incorporate mounting elements in said radiant heater during manufacture of the insulating member. This is achieved by the connecting angle (2) according to the invention, whose one leg is both connected to the heating element (2) and to the connecting line (4) while its other leg is fixed in the insulating member (1). <IMAGE>

Title: Catalyst
Inventor: NIJS GUIDO DIPL ING
IPC: B01J35/04
Filed: 1993-03-02
Abstract: The invention relates to a catalyst to be fitted so that throughflow takes place horizontally, with a reaction chamber having a circular cross-section and a housing surrounding the reaction chamber, the reaction chamber at both of its ends having one opening each whose cross-section in each case is filled by a sieve-like element. The object of the invention is to propose a catalyst in which the formation of voids due to the settling process is prevented. This is achieved by the reaction chamber being filled with catalytic granules and by the housing having a recharging shaft which is open towards the reaction chamber and has a vertical axis, the catalytic granules filling all of the reaction chamber and part of the recharging shaft.

Patent DE-4314018-A1 (DE)
Title: Acoustically controlled time switch for staircase light - enables triggering by manual switches or time=controlled acoustic person sensors
Inventor: SAUSEMUTH OLAF DR RER NAT
IPC: G01V1/00
Filed: 1993-04-23
Abstract: The lighting can be activated by manual switches, acoustic person detectors and spectral analysers triggering a monostable timing element.  Triggering by acoustic sensors is only permitted when preceded by manual activation when the acoustic level is too low for triggering and after automatic time-related switch-off despite the presence of a person. Reactivation by acoustic triggering is then enabled for a defined period (t2), after which the activation of the staircase time switch by the acoustic sensors is blocked. ADVANTAGE - The arrangement enables energy efficient light switching matched to the need.

Title: Hydraulic clutch-actuating device
Inventor: SCHONLAU JUERGEN
IPC: F16D25/12
Filed: 1993-07-21
Abstract: The proposal is for a clutch slave cylinder (clutch-actuating device 1), the piston of which is arranged coaxially with a clutch. The clutch slave cylinder is here flanged directly to the gearbox (2) and sealed relative to the latter by suitable means (13, 19, 30), thus eliminating the possibility that the gear oil and the pressure medium of the master cylinder will mingle. A pressure-maintaining valve (36) is provided to preload the piston (3). An extension (45) on the valve piston (37) allows the hydraulic clutch-actuating device (1) both to be secured for transport and to be filled under a vacuum. <IMAGE>

Title: Method and apparatus for cleaning a venetian blind or the like
Inventor: SKORUPPA DIETER
IPC: A47L4/00
Filed: 1993-09-24
Abstract: To clean a venetian blind or the like, the venetian blind is put together to form a lamellae bundle and introduced into a closable perforated cage. This perforated cage is fixed to a lifting assembly, with the aid of which the perforated cage containing the lamellae bundle is repeatedly dipped into a cleaning container containing a cleaning fluid. Short cleaning times result if the cleaning container is equipped with an ultrasonic transfer arrangement which is operable only when the lifting apparatus is at a standstill, that is when the lamellae bundle which has been dipped into the cleaning fluid is not moved for a preset period of time and is subjected to ultrasound. <IMAGE>
Patent DE-4334202-A1 (DE)
Title: Electric motor having an at least approximately tubular housing section
Inventor: BERTOLINI THOMAS DR ING
IPC: H02K5/24
Filed: 1993-10-07
Abstract: An electric motor is proposed which is preferably used for driving a fan (blower) which is part of the air-conditioning system of a motor vehicle. The electric motor comprises an at least approximately tubular housing section, on whose outer envelope surface a plurality of supporting regions, which are fixed to the housing, are arranged adjacently and at a radial distance, and elastic elements are in each case arranged between the envelope surface and the supporting regions, which elastic elements hold the electric motor in a supported manner on the one hand on the outer envelope surface and on the other hand on the supporting surfaces and suppress exciter oscillations of the operating electric motor. Advantageous decoupling of vibration (oscillation) between the electric motor and the supporting regions is achieved if the suspension system (which is formed by the elastic elements) is tuned to the exciter oscillations of the electric motor such that the natural frequency (eigen frequency) of the suspension system is lower than the exciter frequency of the electric motor. <IMAGE>

Title: Parallelepipedal body with metal shell, core and side edges, connection and distance parts and also coating materials
Inventor: HINZMANN SIEGFRIED
IPC: B28B7/00
Filed: 1994-02-03
Abstract: Parallelepipedal body with metal shell (1, 2), core (3, 5) and side edges (4), connection (6) and distance parts and also coating materials illustrated according to the invention on the example of a vibrating floor, a production aid in the concrete brick factories of the building materials industry. On the vibrating floor, compression and tension conditions are, with wedge-like construction parts (5) which are pressed into the core, generated and fixed simultaneously by the swelling of the relatively dry core wood (3, 5) as a result of its thorough moistening with a glyceric solution and on the metal shell (1, 2) by a temperature-dependent shrinking. The manufacture and application of the vibrating floor according to the invention simplifies its production, increases the service lives of the surfaces (1) and allows the use of sawn timber (3) of lower quality and/or plastics for the core. The vibrating floor presented is completely dismantlable and therefore also recyclable. Conventionally manufactured vibrating floors made of wood which are worn out can with low outlay be used for manufacturing the core (3, 5) in the vibrating floor. The improved surface characteristics (1) of this vibrating floor, its extended period of use and the lower fire load are the crucial product advantages for a user. <IMAGE>

Title: Process for producing a gas electrode
Inventor: WAKITA SHUHEI
IPC: C25B11/12
Filed: 1994-05-18
Abstract: Process for producing a gas electrode, in which a mixture of carbon powder and a fluororesin powder is calcined to form a flat structure for a gas electrode base material, in which one side of the base material is coated with an organic solution which is prepared by dissolving a platinum group metal salt in an organic solvent which is able to form an organic complex with the metal salt, the coating layer is dried and calcined at a temperature of 250-380 DEG C in a protective gas atmosphere, so as to reduce the platinum group metal oxide, with a catalyst layer being formed on the base material. Reduction (calcination) of the platinum group metal salt can be achieved without use of dangerous hydrogen gas and without being accompanied by the decomposition of the fluororesin and provides a uniform catalyst layer comprising fine platinum particles which have a large surface area with a minimised thickness.
