Patent DE-2540429-A1 (DE)
Title: Combined control for windscreen and headlamp washers - with single pump and magnetic inhibit valve for headlamp washers when lights not on
Inventor: SEIBICKE HORST
IPC: B60S1/60
Filed: 1975-09-11
Abstract: The combined windscreen and headlamp wipers and washer control system has a single programme selector switch and an electronic control. A single washer pump provides sufficient water for the windscreen and headlamp jets. The headlamp washers are operated periodically in relation to the wiping action of the windscreen wipers. This saves washing fluid. An electro-magnetic valve in the headlamp washer line prevents the washers from operating if the headlamps are not switched on. The valve is considerably cheaper and simpler than a separate washer pump.

Title: Reproduction system for data carried on tapes - has monochromatic light source and pick-up units for optical signals to be converted to audio output
Inventor: AWENDER HANS DR RER NAT
IPC: G11B7/14
Filed: 1975-09-27
Abstract: The data reading system enables items to be picked up either parallel to or at right angles to the direction in which the information is moving. The light source used is preferably a monochromatic source, enabling optical signals to be picked up under the impetus of a pulse signal. Output information may be to an electro-acoustical converter, such as a loud-speaker or a headphone unit. An additional control enables the tape speed to be controlled by the use of a track in or data track. The main components of the system comprise a cassette (1), tape (2), incident and emergent light rays (3, 4) from light source (7) through illumination and read optics (5, 6), sensor (9), decoder (10), controller (11) visual data unit (13) and audio unit (14). The tape is moved by a motor unit (16) in response to a control system (17).

Title: Two stage leather tanning process - comprises pretanning with a dialdehyde in formaldehyde soln. followed by a mineral tannage
Inventor: LASSEN KNUD
IPC: C14C3/28
Filed: 1975-11-05
Abstract: Leather is prepd. by pre-tanning with a soln. contg. 1 mole of an aliphatic, 2-8C omega,omega-dialdehyde or its acetal in a 10-40% aq. soln. contg. 4-6 moles. HCHO. The soln. is obtd. by mixing at a pH of 5-10 and warming to 80 degrees-95 degrees C. After pre-tanning, the leather is tanned with the usual mineral tannage, omitting the stages of degreasing, pickling and neutralisation. The mineral tannage should contain 1-2.2% Cr2O3, 2.5-4% Al2O3 or 4-7% ZrO2 on bare leather wt. depending on the tube used. Used for the prodn. of white or brightly coloured leather. The use of aldehyde tannages is known, but although white leathers of increased shrinkage temp. could be obtd., no rationalisation or simplification of the tanning process was achieved. This simplifies the operation, reduces the problem of waste disposal and even improves leather quality. In an example chrome leather was prepd. by de-liming, pre-tanning in a mixt. of 30% H2O, 2% of 45% aldehyde compsn. and 2% anionic greasing agent for 30 min. at pH 6.0 and tanning with 6% of a 50% commercial chrome tanning agent (1.3% Cr2O3) for 5h in the drum.
