Title: Automatic replenisher for screen wash fluid - has collector for rain water which is fed through filter to reservoir
Inventor: FISCHER AXEL
IPC: B60S1/50
Filed: 1977-01-07
Abstract: The rainwater is collected in a tray under the windscreen and passed into the screen wash reservoir via a filter (2) so that the reservoir is automatically replenished. The water drains into the reservoir either by gravity or via a syphon. The system extends the range of the vehicle between topping up of the screen wash bottle and eliminates opening the bonnet and soiling the clothes. The filter is easily replaced when clogged and prevents dirt and grit from entering the washer jets.

Title: Drag reducer for ship's hull - has liquefied gas evaporated by controlled flow of sea water with mixt. passed through centrifugal evaporator
Inventor: BELSEN JACOB N
IPC: B63B1/38
Filed: 1977-03-25
Abstract: The underwater hull has its drag reduced by a carpet of gas bubbles over the outside of the hull. The gas is derived from a liquified store inside the hull, the liquid being evaporated by the warmer seawater. Seawater is introduced at the front of the hull and mixes with liquified gas in a mixing chamber to vaporise the gas. A simple centrifugal separator provides the pressurised gas flow to feed the carpet jets spaced about the hull.

Title: Keyboard synthesiser with programmable facility - has digital memory to store keyboard note sequence which may be replayed
IPC: G10H1/24
Filed: 1977-08-25
Abstract: An electronic keyboard instrument includes a digital memory stage to provide a programmable mode of operation.

The signal is amplified (6) and is transmitted over a relay (7) to the output amplifier (VCA). The signals are directed over an A/D to a multiplexer (9) and are entered into memory (M) over a controlled address. When the manual/programme selector is switched the contents of the memory may be read and demultiplexed (14) through a D/A to output.
Patent DE-2739152-A1 (DE)
Inventor: BISCHOFBERGER WALTER
IPC: H01H1/46
Filed: 1977-08-31
Abstract: In an electrical plug contact arrangement for a switching device with at least two contact pieces which move against each other, a known method is that one contact piece has at its free end, which faces the other, opposite contact piece, a contact lamination cage with sprung contact laminations, which make the electrical connection with the opposite contact piece. In such a contact arrangement, so that it is possible to move the contact pieces in and out reciprocally in both the axial (longitudinal) direction and the radial (at right angles to the longitudinal) direction, and furthermore to move them in and out at right angles to the axial direction and the respective radial direction if they depart from their nominal position, the essentially U-shaped contact lamination cage (1), which has the contact laminations (4) arranged in packages in its two profile legs (1a, 1b), is coupled to the cross-pieces (1c) which link the two profile legs (1a, 1b) so that it can be swivelled, by fasteners (6) at the free end (2a) of one contact piece, which is in the form of a contact flange (2). The plug contact arrangement can thus compensate not only assembly tolerances, but also heat expansion and elastic oscillations between the contact pieces (2, 3). <IMAGE>

Title: Variable luminance luminescent lamp - has small diameter tube and dark and light patterned sleeves to vary light intensity
Inventor: VEDRES LAURENT
IPC: F21V9/40
Filed: 1977-12-14
Abstract: A lamp with a system of varying its light intensity uses a small diameter luminescent tube or cold light source which can be mounted inside tubes which are rotated and/or raised and lowered to vary the intensity. The lamp can be mounted on feet to stand vertically. The tubes which vary the intensity of the light are formed of alternate dark and light bands or of a special pattern of dark and light regions so that their interaction with one another has the varying effect. Either the inner tube or the outer tube may be moved. The luminescent tube itself may be one of the patterned tubes.

Title: Non-magnetic workpiece surface finishing - uses ferromagnetic grinding powder in magnetic field with ferromagnetic rods between workpieces
Inventor: SAKULEVITSCH FADDEJ J
IPC: B24B31/10
Filed: 1978-05-18
Abstract: The finish machining of surfaces on non-magnetic workpieces uses ferro-magnetic grinding powder in the magnetic field which is produced by opposite unlike poles of a magnetic system. The ferro-magnetic powder is arranged in the magnetic field and a so called 'cutting brush' of the powder is formed. Non-magnetic workpieces are then introduced into the field and are moved with respect to the 'cutting brush'. A ferro-magnetic body (6) is arranged between each pair of non-magnetic workpieces (3) and thus is moved with respect to the 'cutting brush' of ferro-magnetic powder (1) and ensures the re-making of the cutting brush. The ferro-magnetic body (6) has an aerodynamic profile.

Title: Insulating window parapet construction - has anchored profile bar with low heat conductive filling between itself and gripping anchor
Inventor: HACK GUENTER
IPC: E04F19/00
Filed: 1978-07-31
Abstract: The profile rail-shaped bar serves as support for heating units, window sills and other fittings when anchored to a window parapet, without cold bridge formation. Use is made of two types of two complementary members. One is in the form of an anchor (19) attachable in the area of the window parapet walling, displaceable lengthways against the line of the profile bar (4). The other is the bar itself. One of the two has shanks bent over to grip the other. The intervening space is filled with integral foam, or other material with low heat conductivity, firmly connected to one member. This provides effective heat and sound insulation with various types of parapet construction and heating units.

Patent DE-2840987-A1 (DE)
Inventor: DORNER ARMIN DIPL ING
IPC: C10G69/06
Filed: 1978-09-21
Abstract: Hydrocarbons are subjected to hydrogenation, pressure reduction and separation into liquid and gaseous fractions. The gaseous fractions are purified and desulfurized. Hydrogen-rich components of the gaseous fraction are returned to the hydrogenation stage. Hydrocarbon-rich components of the gaseous fraction and components of the liquid fraction are cracked and fractionated. Residue is partially oxidized with oxygen and steam. Gas produced by the partial oxidation is desulfurized and separated, and hydrogen is returned to the hydrogenation stage. A polymer free fraction of the residue is returned to the feed stock and to the hydrogenation stage, a heavy residue component of the initial liquid fraction is partially oxidized with the residue.
