Title: Sludge compsn. with paper/foil shreds - by removing excess water in worm-type extruder press
Inventor: SPOHN EBERHARD DR
IPC: C05F7/00
Filed: 1973-09-04
Abstract: The conversion of refuse and sewage sludge contg. chopped and sorted shreds of paper and foil is preceded by an intensive kneading process. Conventional kneading machines reduce the mass to irregular crumbs. In the addn. prior to kneading, an excessive amt. of liq. is added to maintain a sludge which is pressed cut during the kneading operation under pressure until the mass has a uniform moisture contact of 30-60 wt. %. Flocculants can be added and the mass breaks up into irregular crumbs. This crumbly compost has a homogeneous moisture content which is kept at the optimum figure for aerobic rotting by adjustment of the press force. No separate dewatering is necessary, saving centrifuges or filter-presses. The rasping holes are not clogged up by the sludge.

Title: Fuel injector pressure regulator for low pressure fuel injection - regulating pressure is taken from mean cylinder working pressure
Inventor: MIEBACH ROLF
IPC: F02M69/20
Filed: 1974-02-04
Abstract: Fuel pressure reduction valve whereby by the mean exhaust pressure or the mean crank case pressure is used to regulate a membrane to control the fuel flow as in 2138543 is improved so as to avoid an over rich mixture. The regulator pressure input from either crankcase or exhaust is broken at a suitable place and joined to the induction after passing the throttle valve position. This avoids the possibility of engine lubricating oil clogging the regulator valve and membrane. The regulator pressure is now taken from a piston regulated aperture from one or more working cylinders of the engine, to represent the average cylinder pressure during part of the compression and working strokes.

Title: Self-coiling heat-shrinkable recovery cord - for absorbent tampon for use in female hygiene
Inventor: PIETSCH HELMUT DIPL CHEM DR
IPC: A61F13/20
Filed: 1974-05-16
Abstract: Tampon fro female hygiene consists of an absorbent body with a recovery cord composed along its length partly of non-heat shrinkable material and partly of heat-shrinkable organic synthetic material. The heat-shrinkable material enables the cord to fold or coil itself independently of the compsn. and method of prodn. of the tampon itself. Pref. the cord is securely fixed to the centre of the wound-up tampon blank so that it extends freely from one end. A tacking stitch of heat shrinkable yarn may extend over the full length of the cord, which may otherwise consist of cotton or cellulose not shrinkable when heated. After heat treatment the cord coils or folds up naturally due to the asymmetric shrinkage.

Title: Stabilised front wheel suspension strut - with off axis strut mounting for longer strut not prone to seizure
Inventor: HAVERBECK GUENTHER DIPL ING
IPC: B60G7/00
Filed: 1974-07-02
Abstract: The front wheel is freely rotatable and is supported by a long telescopic damper (1).

Title: Hydraulic control for automatic transmission - with two stage pressure control for improved matching to engine torque
Inventor: KALVERSBERG MANFRED
IPC: F16H61/00
Filed: 1974-10-17
Abstract: The automatic transmission is fitted with a pump which provides a control pressure related to the engine speed. This pressure is modulated by a second control valve which is spring loaded, and which is subjected to a wheel speed related pressure in such a way that the first pressure signal is passed through the second valve below a set road speed. For an improved matching of the gear setting with the torque, a two stage second control valve is fitted, using a stepped piston element, with the first stage ensuring a stable control and with the second stage controlling a reversing valve which relieves the control valve from the spring pressure below the set road speed.
