Patent DE-1805932-A1 (DE)
Title: Sewage sludge tank agitator
Inventor: ROEDIGER WALTER
IPC: C02F3/28
Filed: 1968-10-30
Abstract: Sewage sludge tank agitator provides for motion of contents in all directions. G6B. it consists of a conveyor spiral produced in downwards facing conical or bell form from strip applied to a shaft. The shaft is pivotable sideways, to describe the envelope of a double cone. The customary crust which may be left on the surface, to hinder gas escape and contents circulation, is thus broken up. The whole unit is withdrawable during operation of the tank.

Title: Distance travelled meter for trains - pulse generator output fed to adjustment unit for accurate calibration for wheel diameter
Inventor: SANDER HEINRICH DIPL-ING
IPC: G06F7/62
Filed: 1973-07-11
Abstract: A system for measuring distances travelled by a railway vehicle, in which the rotation of the wheels of the vehicle generates pulses dependent on the direction of travel and the number of pulses is counted to give the total number of revolutions and hence the distance covered. A unit is inserted between the pulse generator (WR) and the counter (Z3) which multiplies the number of pulses and this unit is connected to another which converts this larger number of pulses to an adjustable smaller number. The adjustment permits of exact calibration, for example to compensate for reduction in wheel circumference due to wear.

Patent DE-2337917-A1 (DE)
Title: Solvent extraction of solids - by rotating extractor with programmed injection of fresh solvent
Inventor: BECKER KENNETH W
IPC: B01D33/19
Filed: 1973-07-26
Abstract: Rotating solvent extractor for solids as described in DT 2337916 having timing devices which control the injection of fresh solvent so that a quantity sufficient to leach out the charge in each cell is injected. Each cell has a key, the posn. of which is sensed by a follower and there is a delay mechanism which delays opening of valve until the rotor reaches the correct posn. The follower is connected to a switch. The delay following closure of switch is controlled by timers, which generates different time signals one after the other. This is used for extraction of oil from solids and avoids excessive use of solvent and this excessively weak rich solvent by counter-current action and controled solvent injection.

Title: Ladder with stringers and rungs - stringers as facing bows meeting at rungs for welding nodally
Inventor: LARSSON ERIC SIGFRID
IPC: E06C7/08
Filed: 1973-08-27
Abstract: Ladder with stringers and rungs between, each of whose stringers consists of two identical mirror image bows joined to each rung and thus to each other. Each bow is cranked so as to grasp halfway round the respective rung and be welded to this here. Preferably the bows are circular in section, the rungs being square so that one of the rung diagonals lies in or parallel to the longitudinal centre plane of the ladder itself. The bows should project forward and to the rear of the rungs respectively, and then run in at both ends to join at the rungs from above and below. A clamp can be fitted to the straight parts of the bows at intervals to stiffen the stringer assembly.

Title: Contactless push-button switch with adjustment device - has integrated circuit with transistors and hall generator
Inventor: PFEFFER JOSEF
IPC: H03K17/97

Title: Antenna with flexible rod - comprising helical spring embedded in elastic layer
Inventor: KLINKWITZ KURT
IPC: H01Q1/40
Filed: 1973-11-17
Abstract: The antenna comprising a flexible antenna rod, made from a self-supporting helical spring and an elastic layer surrounding the spring is improved as regards mechanical resistance, as required, by embedding the helical spring in the elastic layer, which consists of an insulating matl., having rubber-elastic props. This may be natural or synthetic rubber, into which the helical spring is incorporated by vulcanisation.

The antenna is e.g., a car aerial which will bend and not break on entry into low garage or passage through car wash.
Patent DE-2359244-A1 (DE)
Title: Removing lubricant from engines and gears, axle drives - involves sucking oil out with pump and pipe, or pressure expulsion
Inventor: BREUSTEDT KONRAD
IPC: F01M11/04
Filed: 1973-11-28
Abstract: Liquid lubricants are removed from engines, gears, and intermediate and axle drives of motor vehicles; the lubricant is sucked out with a pump and a pipe or hose when the drain hole is not usable. Preferably, instead of sucking with reduced pressure an increased pressure may be applied to the surface of the lubricant, to push it out. No outlet drain opening is required, and uncontrolled deposition of waste oil onto the ground is avoided. The procedure requires an enlargement of the otherwise present opening used for sucking out, the production of additional openings when the existing ones are insufficient, and the use of the outlet opening for sucking out and producing pressure on the liquid surface instead of suction.
Patent DE-2359704-A1 (DE)
Title: Games or football with surface elevations - elevations uniformly distributed for braking action on rolling on ground
IPC: A63B41/08

Abstract: Game ball or football has knobs or elevations distributed uniformly over the surface of the ball and exerting a given braking action on the rolling of the ball when it reaches the ground. The design may be used for all kinds of balls. Playing children can keep the ball under better control, and it is better for convalescent persons taking exercise. Less time is required for recovering the ball in football training. The braking effect can be regulated by the shape, type, number and distribution of the protuberances.

Title: Concealed wide angle hinge for furniture doors - has sliding and pivoted mountings on door panel and frame
Inventor: VITT THEO
IPC: E05D3/18

Abstract: The concealed hinge allows door rotation through half full circle and the hinge is completely concealed when the door is closed. The hinge end on the frame is able to slide and the hinge end on the door is pivoted. The hinge linkage is stable against twisting by the door panel weight. A sliding lever is pivoted at the middle about a pin in an intermediate lever. The frame end of the lever slides in the slots of a guide by its pin. The sliding member is also guided laterally between the guide members which have slots. The door panel is lifted clear of the frame on opening and the combined hinge allows the door panel to rotate through half a full circle while the hinge mechanism becomes fully exposed.
