Title: Windscreen wiper blade, on vehicle - is locked to arm via U=section coupling pivoted to blade and closed by locking device after insertion of arm end
Inventor: ZORN GUENTER ING GRAD
IPC: B60S1/40
Filed: 1978-11-04
Abstract: The motor vehicle windscreen wiper comprises a wiper arm (12), a wiper blade (14) to one side of the arm, and a coupling element (18) which is pivotally connected to the blade and contains a channel (42) to receive the end (12) of the arm. The entire length of the channel is contained between three walls (36, 38, 40) forming a U-section. The end (12) of the arm is inserted through the open end facing the base wall (40) of the U-section and can, at least partly, be closed by a plate (54). The closure (54) may consist of a plate which is capable of locking onto both side walls (36, 38) of the U-section.
Patent DE-2903964-A1 (DE)
Title: Wet mechanical purificn. of impure bulk material - esp. accumulator scrap travelling via gravity down shaft fed with water employed to wash the scrap
Inventor: FISCHER RUDOLF
IPC: C22B7/00
Filed: 1979-02-02
Abstract: The material is fed into the top end of a shaft together with a washing medium, e.g. water, which wets the material and removes water-soluble cpds. The mixt. of material and water then falls via gravity onto a row of impact plates arranged as a cascade, so thorough mixing occurs. The impact plates pref. cause the mixt. to flow in alternate directions, and the process is pref. employed as a preliminary treatment prior to further wet mechanical refining. The process is used esp. for the treatment of battery accumulator scrap, the pref. plant including a shaft contg. a vertical stack of curved impact plates. The crude scrap is fed by a conveyor belt into the top of the shaft, which also has a water inlet. No moving mechanical parts are required in the shaft, in which the mixing effects are obtd. via gravity, and washing is very efficient. Pressurised water is not used, and thus the formation of noxious aerosols is avoided.
Patent DE-2911474-A1 (DE)
Title: Rotating piston IC engine - has circular cylinder and diametrically arranged piston flanges attached to separate, concentric drive shafts
Inventor: ZABEL WILFRIED
IPC: F01C1/063
Filed: 1979-03-23
Abstract: The cylinder is or circular corss section (2). Inside, and pivoted at the centre, are piston flanges (8, 9, 10, 11) attached to separate but concentric drive shafts. The pistons are axially in line inside the cylinder. Arrester elements (12, 13) hold, in succession, the piston flanges during power strokes. Inlet and outlet gas ports (14, 15, 16, 17) are approximately midway between arresters. Sparking plugs (18, 19) are at a small angle in direction of rotation (A) from the arresters. During the power stroke one piston is arrested whilst the other turns due to the expanding gas which acts on all the flange are. The arresters release and an induction stroke follows whereupon the other piston is arrested and the cycle repeats. Practically the whole reaction of the ignited fuel mixture reacts on the piston. The sealing arrangement at the cylinder-piston interface is simpler with a circular cylinder.

Title: Rotary internal combustion engine - has double acting cylinders and double acting pistons in contra-rotation to eliminate reciprocating parts
Inventor: GOEDECKEMEYER ULRICH
IPC: F01B7/00
Filed: 1979-05-21
Abstract: The engine has four double acting cylinders with four double acting pistons. Each is connected by a crankshaft to a common main shaft. Gears between them and the main shaft ensure a contrarotation of the cylinders and pistons which results in a rotary output without reciprocating parts. Separate pumps deliver cooling liquid to the cylinder heads and pistons. The exhaust takes place through a port controlled by the rotation of the cylinder. Suction takes place through flap valves which are parallel to the direction of the centrifugal force at the correct time for opening.

Title: Wood impregnation, filling and staining - involves initial medium volumetric measurement to assess quantity needed for penetration
Inventor: SKRZIPCZYK JOHANN
IPC: B27K3/08
Filed: 1979-06-01
Abstract: Before immersion in protective impregnating medium takes place wood is vented under vacuum in a pressure vessel, in a process for impregnation, filling and/or staining wood. The impregnating medium is volumetrically measured during filling so that the differential between vessel volume and measured quantity can serve as basis for adding the amount needed for penetration into the wood, under pressure. Immersion pref. lasts between 1 and 3 minutes, and the wood to impregnating medium volume ratio is pref. not less than 3:1. Precise quantities can be applied, in a short time.

IPC: G01K7/24
Filed: 1979-08-23
Abstract: The frequency analogue multiple sensor for simultaneous measurement of several physical parameters at a measurement point is compact and reliable. A monolithic integrated semiconductor chip (15) contains a number of frequency analogue individual sensors equal to the number of parameters to be measured. Each sensor contains a ring oscillator (23,24) formed in IIL circuitry and a measurement resistor (21,25). The resistance of the measurement resistor varies with the measured parameter and controls the injector current of the co corresp. ring oscillator. One sensing resistor is temp. dependent. The temp. dependent resistor is formed by dosing a defined region of the chip with a different material of n or p type with a concentration of 10 power 15 to 10 power 16 per cu cm. Another sensing resistor is made photosensitive by below surface doping.

Title: Video display for ultrasonic scanner - has piezoelectric target with conducting raster scanned by sampling electron beam
Inventor: MOERZ GUENTER DR ING
IPC: G01S15/89
Filed: 1979-10-08
Abstract: The video display is for an ultrasonic scanner and has a piezoelectric target (4) scanned by an electron beam (S) and moved by the echo signals from the subject. The rear of the target is coated with a conducting raster with a set emission coefficient. The piezoelectric sheet translates the echo signals into electric charges on the rear raster coating.

Title: Combined loudness and tone control - has selected bass or treble enhancement using switchable capacitor position
Inventor: GOLDBACH STEPHAN
IPC: H03G5/04
Filed: 1980-03-13
Abstract: The switchable capacitor circuit is placed between the front (1) and final (7) amplifiers in a loudness control circuit.
