Title: Electro-optical recorder for TV signals - records vision and sound on photosensitive strip and reduced image is arranged as spiral-track record
Inventor: NATHAN GUY ERNEST
IPC: H04N5/85
Filed: 1973-06-28
Abstract: An electronic-optical method for recording television signals is used for producing recordings for replay on domestic television receivers, in which in a first stage the luminance signal and the chrominance signal without carrier are recorded on a continuously running black and white film with that part of the chrominance signal corresponding to the synchronising pulses in the luminance signal suppressed, using a holographic scanning technique; the sound track is recorded on the same film which after development is projected in reduced form to produced a master recording disc in which the image of the film is extended along a spiral track; the master may be reproduced as often as desired to give recordings from which an enlarged image is obtained to reproduce the recorded film; a matrix of photodiodes ensures correct control of the scanning during reproduction.
Patent DE-2336959-A1 (DE)
Title: Squeeze tube dispensing device - spring-loaded compression piston unit fitted to outlet nozzle
Inventor: WALTER JOSEF
IPC: B65D35/40
Filed: 1973-07-20
Abstract: The tube is fitted tight in the opening on the top of the holder which can be fastened on one side and has a supply channel which is linked with the opening via a non-return valve and follows a U-path to the outlet opening. A spring-loaded piston is connected to the supply channel and has a non-return valve which can be operated to cause under pressure in the part of the channel beneath the opening of the holder and excess pressure in the region leading from there to the U-bend. This causes a part of the contents in the tube to be removed down into the first part of the U-shaped-supply channel and also causes the part of the tube contents located in the supply channel to the outlet opening, with the two non-return valves openings and closing alternately. The outlet opening is closed by the actuating member which is pressed in to trigger the piston pump action.

Title: Berlin blue prodn - by reacting magnesium ferrocyanide with ferrous salt and oxidising the resulting berlin white
Inventor: REINHARDT HELMUT DIPL CHEM DR
IPC: C09C1/26
Filed: 1973-12-18
Abstract: Berlin blue prodn. by reacting a ferrocyanide with a Fe(II) salt in an aq. medium having pH 7; converting the resulting acid salt into Berlin white by reaction with an inorg. or org. potassium salt at pH of 1 (or less) to 6; and oxidising this prod. to Berlin blue; is improved by using Mg2 Fe(CN)6 as a ferrocyanide. The reaction between Mg2 Fe(CN)6 and a Fe(II) salt can be carried out in an only slightly acidic medium so that there is no need to use an appts. made from a highly anti-corrosive matl. FeSO4 can be used as a Fe(II)-salt, because it does not form any insoluble salt with Mg. The quality of the prod. is good.

Abstract: A free-flowing, heat-hardening moulding compsn. contains (a) an unsatd. polyester, (b) an ethylenically unsatd. comonomer, (c) a cellulose ester with viscosity (ASTM D 871-56, formula B) is not 10(12-24) secs., and opt. (d) fillers, fibrous reinforcing agents, pigments, polymsn. initiators, release agents, thickeners and polymsn. inhibitors; the amt. of (c) is such that after mixing at increased temp. and cooling to room temp., the prodt. is a clear, solid, gel-like compsn. with a dry surface. The compsn. is used in injection moulding. The compsn. contains less filler than previous mixes, and gives strong mouldings. Shrinkage during hardening is negligible. Moulded goods have smooth, glossy surfaces, and are true to the shape of the mould. De-moulding is easy. Thick mouldings show no inner cracking.

Title: Depression dependent fuel injection regulator for I.C. engine - has accelerator fuel feed compensator for cold running period
Inventor: STUMPP GERHARD DIPL ING
IPC: F02M69/22
Filed: 1974-01-24
Abstract: Fuel is continuously metered to the injectors situated in the inlet manifold from unions in the fuel metering and distributor unit, whose metering valve regulates the fuel flow from an electrically riven fuel pump in proportion to the movements of a disc pivoted at the entrance to the air intake pipe. In order to provide a richer mixture on sudden acceleration when the engine has not reached working temperature, a pressure switch consisting of a membrane forming two chambers with one chamber connected to the air intake between filter and disc and the other to a pressure compensating valve, has an electric contact in series with a temperature dependent switch, the electro-magnetic valve of a fuel injector and the positive battery pole. A sudden pressure drop when the throttle valve is opened causes the diaphragm to overcome the spring pressure in the barometer box and close the contacts to excite the injector magnet and enrich the fuel supply, the duration being dependent upon the size of the restrictor in the pressure compensator non return valve.

Title: Wiper for window of car - with magnetic coupling through glass pane from motor via reduction gearing
Inventor: GELHARD EGON
IPC: B60S1/08
Filed: 1974-08-21
Abstract: The rear windscreen wiper has the electric wiper motor directly coupled to a permanent magnetic drive and attached to the inside of the windscreen, which is not drilled. The other side of the windscreen has a second part of a magnetic coupling comprising a similar permanent magnetic system to follow the magnetic drive. The coupling drives a reduction gearing as well as an eccentric, rotating drive which converts the circular movement of the drive into a reciprocating shaft drive. The gearing is compact and does not reduce the rear windscreen visibility to a great extent. The wiper is simple to fit to any vehicle and does not require any holes bored in the window, nor any weather protection for the electric motor.

Title: Contactless determination of liquid levels - sound pulses reflected from above boundary surface for distance measurement
Inventor: CLAUSSEN REIMER DIPL PHYS DR
IPC: G01F23/296
Filed: 1974-09-16
Abstract: Liquid levels or levels of solid loose material in rivers, tanks, channels etc are determined as follows. Sound pulses from a fixed sender-receiver station are reflected from the boundary surface, and the propagation time both ways is used for distance measurement. Each sound pulse is transmitted over the measurement path and a reference path of known, presettable length. The time taken in both ways over the reference path is measured by a constant number of counting periods, and pulse frequency is changed until the specified number of periods exactly corresponds to the time taken by the echo from the reference path to return, so that each counting period corresponds to a known fraction of this path length. The time taken by the pulse to travel there and back over the measurement path is measured by counting periods of the same frequency, so that the distance is directly obtained by simple multiplication.
