Title: Automatic switch for uncoupling front wheel drive - uses switch linked to higher gear settings in four wheel drive transmissions
Inventor: DIRNBERGER HEINZ
IPC: B60K23/08
Filed: 1975-01-25
Abstract: The front wheel drive is switched on by an electro-magnetic valve operating on a hydraulic servo line. The control line to the valve is fitted with a manual selector switch so that the driver can select four wheel drive. The gear lever into the main gear box is linked to a second switch which blocks the line to the electro-magnetic valve when the gear lever is moved into the higher gears. The high-low ratio control gear lever is likewise fitted with a switch in the control line so that the line is blocked when a high ratio is selected. The fail-safe system prevents the four wheel drive being engaged when the vehicle is operating at higher speeds, in which condition the drive can be damaged.

Title: Defelting treatment fluid - contains reactive copolymers and amino silanes to give a rapid and continuous process
Inventor: ROESSLER ERICH
IPC: D06M15/29
Filed: 1976-01-09
Abstract: Defelting of woollens, and fabrics wiht a wood content is effected by immersion in a finishing fluid with water, removal of surplus fluid followed by drying, heating and decating. Reactive copolymers are added to the watery treatment fluid, based on unsaturated ethylene compounds contg. reactive groups of N-methylol or with 1-3C alcohols ether-treated N-methylol groups, together with catalystic quantities of amino silanes. Process gives a simple, rapid and continuous treatment of woollens which prevents felting, without affecting the surface handle. The material shrinks minimally and on being machine-washed, there is little pilling or snagging. Soil release agents can also be used without affecting the stability of the treatment fluid.
Patent DE-2608640-A1 (DE)
Title: Combining steam power processes with carbon-rich fuel gasification - esp. of coal underground, for hydrogen production under economic conditions
Inventor: BACHL HERBERT PROF DR ING
IPC: C10J3/00
Filed: 1976-03-03
Abstract: In a low pressure stage of the steam power process, the steam is given an intermediate superheating, to a temp. at which, >=10% of the steam fed to the gasifier is split. The released oxygen and the carbon are combined and the remaining energy of the steam/gas mixt. leaving the gasifier is returned to the steam power process. The remaining heat may be utilised in a waste heat boiler or the steam/gas mixture may be fed to the low pressure end of a turbine. Between waste heat boiler and turbine an electrostatic filter is fitted. The system is esp. suited to the underground gasification of coal, and the energy required for the repeated vaporising and condensing of large amts. of steam necessary in the process for obtaining hydrogen, can be converted into mechanical or electrical energy. The difference between the present and conventional techniques is that in a low pressure stage a (second) intermediate superheating to 900 degrees C is undertaken. Relatively to the steam applied, much more hydrogen is produced much more economically.
