Title: Magneto-mechanical keyboard with magnetic key retention - has electromagnetic key release using defined coil field
Inventor: SEEMANN FRITZ
IPC: H01H13/74
Filed: 1973-06-16
Abstract: The keyboard has several push-button keys which are secured in depressed condition by a permanent magnet.

Title: Coupled slipring motor drive - has frequency converter on one motor only whilst rest run at high slip
Inventor: REIF GERHARD
IPC: H02P5/74
Filed: 1973-09-20
Abstract: The application is to variable speed drives for cranes, where to or more motors are mechanically coupled and operate over a large speed range. A measure of economy in cost and space is achieved by having a frequency converter for one motor only. When operating at low speed the motor connected to the converter sets the speed. The other motors are connected to the mains supply, but these have their rotor resistances set for a high value of slip. In this connection their speed is governed by the motor with the low frequency supply.

Title: Automatic metering of reagent to batch reactor - for azo dye prodn having sensor vessel on recycle line round reactor
Inventor: SCHUPMEHL LEO
IPC: B01J4/02
Filed: 1973-10-20
Abstract: The input of a reaction component to a batch reaction making azo dyes is controlled by measuring its concn. in the reactor by recycling the reactor contents though a cell cont. a sensing element, and using this signal to control the input of the component. In this cell or vessel is a tungstanglass measuring lattice to determine the redox potential, having pH compensation. This potential remains constant for the addn. of diazo soln. up to a certain point and then drops to zero. At this pt. the flow is set to a second valve and reaction continues. At the end, the potential gives a jump indicating complete reaction and the valve is closed. The lattice of fungstan/glass has automatic brush cleaning. It is connected to a controller comprising an adjustable programmer, an rH meter, a two point controller, a voltage source and a servo motor. The start of the measurement is controlled by a set point controller which acts as switching device for controlling input of reagent. Used for the automatic prodn. of azo dyes, normally mafd. in batch reactors.

Title: Bridge bearing esp. for saline atmosphere - has hot sprayed coating contg. oil which precipitates on cooling
Inventor: RUELING FELIX RITTER VON
IPC: B05D5/08
Filed: 1973-12-18
Abstract: A method of nand materials for) spray coating a bridge bearing is as follows: at least the first layer of the coating esp. of cellulose aceto-butyrate, is applied hot (>70 degrees C) by heat-spraying or flame-spraying onto the bearing; as it cools, it precipitates an oil film onto the surface of the bearing, to underly the coating. Pref., the hot gas curing the spray operation removes all traces of moisture from the bearing surface. In addn, a further layer of similar to compatible material, e.g. cellulose aceto-butyrate or cellulose propionate, contg. no oil, is pref, applied after the first. After this, a mould may be fitted around the coated surface, and the void filled with a flexible foam, esp. polyurethane-based. Used esp. near salt water, where excessive corrosion can occur. The heat and the deposition of oil on the bearing prevent moisture attack.

Title: Cross point screwdriver tip - has edges of cross rounded slightly to limit tightening torque
Inventor: GIETZELT RUDOLF
IPC: B25B15/00
Filed: 1974-04-05
Abstract: The tip has a rounded part on its sides in the edge area intended for the extraction of screws.

Title: Automatic regulator for weld seam cleaner - has grinding disc whose application pressure is controlled by spring loaded flaps
Inventor: MUELLER MATTHIAS
IPC: B31B1/74
Filed: 1974-04-08
Abstract: The automatic regulating and controlling device is for a tool for cleaning the welding seam zone of plastic bags where the application pressure necessary to clean the welding seam zone by means of a rotating grinding disc is exerted by two application flaps fitted parallel to the transport direction, which can swivel about a common turning point. Because of long tension springs in their functional region, these flaps have an approximately constant spring force. The wear of the grinding disc over a long time is automatically compensated and simultaneously a signal is produced via a proximity switch when a given degree of wear of the grinding disc makes necessary a post regulation. Specifically, the wear compensation is regulated by a setting motor with a spindle.

Title: Vehicle gas turbine with compressor-driving and output turbines - with space-saving means for balancing centrifugal force
Inventor: MAI HORST
IPC: F02C7/36
Filed: 1974-07-10
Abstract: Vehicle gas turbine comprises a gas generator including a compressor, combustion chamber and a compressor-driving turbine (3), and and output turbine (13) connected to the compressor-driving turbine via an internal direction-dependent coupling, e.g. a free-running coupling (11, 12).

Title: Permanent magnetic contact pressure intensifier - has magnetic switching armature opposite pivoting magnet and magnetic compensation
Inventor: LUEHN OSKAR
IPC: H01H5/02
Filed: 1974-10-03
Abstract: The contact pressure intensifier permits application of a slight actuating force only. It has a pivotally mounted, diametrally poled magnet, to which is oppositely mounted a switching armature (6) with a magnet (7). This produces a rotary moment, e.g. of clockwise direction on the magnet (1), which is so compensated by a magnet (10) that the magnet (1) is brought into unstable state. This results in the requirements of a negligible force for moving the switching lever (3), this force being considerably lower than the switching force exerted on the switching armature. Preferably a ferromagnetic screw or miniature magnet is provided for increasing the resetting force of the armature into its starting position w.r.t. the magnet (7).
