Title: Electrically operated door holding device - has stop bolt screwed out from and into sleeve fitted beneath door lower edge
Inventor: SCHOEPE ERWIN
IPC: E05B47/02
Filed: 1979-05-26
Abstract: The device can hold the door open in a required position or can hold it in position against the sill. It is secured to the underneath of the door and uses a door stop bolt which can be pushed down to the floor by foot. Pref. a 6 volt electric motor is energised when the door stop is operated to cause the stop bolt to be screwed outwards from a sleeve inserted beneath the bottom of the door, the being motor again energised when the door is released. Thus the bolt is screwed back into the sleeve. In these two operations the motor turns in opposite directions.

Title: Overflow prevention in water cooled tumble-drier condenser - using temp. controlled switch located below overflow lip
Inventor: PFARR HORST
IPC: D06F58/24
Filed: 1979-10-09
Abstract: An open-flow, water-cooled condenser for a domestic tumble- dryer has a temp. controlled inlet valve for the cooling water which is open only when the temp. of the exhaust air exceeds a pre-set min. value. The temp. controlled switch is located in the condenser housing at a sufficient depth below the overflow lip that, if the water outlet becomes blocked, the switch is immersed in the rising water and cooled below its shut-off temp. before the water reaches the lip. This is a simple and inexpensive way of preventing damage by overflow water, requiring no additional components or elaborate design alterations.

Title: Resistance welding machine with roller seams and guide - has shifting push rod for weld material linked to separator jaw introducing bend
Inventor: JUDIN IVAN EFIMOVIC
IPC: B23K11/06
Filed: 1979-11-12
Abstract: A roller seam resistance welding machine, which consists of a frame with two electrically linked welding electrodes facing each other. The weld material is accurately shifted to the contact zone of the workpiece and the welding electrodes. One of the electrodes can be shifted closer to the other to generate an elastic compressive force in the welding zone. There is a guide forcing the weld material into the welding zone. The shifting mechanism for the weld material on the welding electrodes contains a pushrod linked to the drive jaw of the separator. The rod transmits a force to the welding material introducing a bend which it retains until the instant it is broken off.

Title: Laundry tumble-dryer with automatic switch=off - controlled by measured electrical resistance of load with automatic correction for load size
Inventor: STEUDEL GOETZ DIPL ING
IPC: D06F58/38
Filed: 1979-11-13
Abstract: A laundry tumble-drier with an automatic switching circuit to switch off the machine when the moisture content of the load, as measured by its electrical resistance, has fallen below a threshold value, has a second detector in the control circuit which raises the threshold value in inverse proportion to the frequency and duration of the contacts between the load and the resistance probe. This prevents premature switching-off when the drum is only lightly-loaded and the load makes only intermittent contact with the probe, giving an indicated moisture content below the actual value.

Title: Processing of natural gas contg. nitrogen - by passage over nickel catalyst of accurately controlled particle size
Inventor: GEUS JOHN WILHELM
IPC: B01J23/755
Filed: 1979-11-15
Abstract: Methane is fed at 80-500 degrees C over a nickel catalyst with >=10 wt.% of nickel on a carrier, for the production of carbon and hydrogen. The nickel has the form of particles which are smaller than 20 nm and the catalyst, loaded with carbon, is periodically regenerated in the normal manner. The size of the nickel particles is pref. between 3 and 6 nm. The methane gas is pref. processed at 100-300 (120-180) degrees C. The nickel content is >=30 wt.% and the ratio of nickel to carrier may be as 95:5. A mixt. of methane and nitrogen is fed over the catalyst and the H2 and N2 are sepd. by adsorption of the H2. Regeneration of the catalyst takes place at between 150-400 degrees C. Used for the conversion of poor natural gas mixt. into gas mixtures which can be used economically in industry. The technique employed makes it possible to break down methane at a relatively low temp. using a nickel catalyst.

Title: Accident warning system for vehicle - has inertial slide switching on flashing warning lights on impact or hard braking
Inventor: FACKLER RAINER
IPC: B60Q1/52
Filed: 1980-01-29
Abstract: The warning system has a slide moving against the action of a spring in the direction of the vehicle's travel and switching on warning lights as a result of the deceleration occurring when the vehicle is braked.
