Patent DE-2929240-A1 (DE)
Title: Twist free blade arrangement for scissors - have bore of joint deviated from blade surface perpendicular axis in both longitudinal and lateral direction
Inventor: RAU ALFRED
IPC: B26B13/28
Filed: 1979-07-19
Abstract: The bores in the two joint parts of the scissors are not perpendicular to the cutting surfaces of the blades but deviate by a certain amount in the scissor longitudinal as well lateral direction. This results in a double oblique position of the blades against each other obviating from production point of view the necessity to twist the blades off the position of the handle plane and also the operation of hollow grinding of the blade cutting surfaces. The two blades meet along their entire length in a point contact with the material to be cut in between. The blades have plane cutting surfaces.

Title: IC engine with oscillating piston - has oil release ports from cylinder sectors to sump with wiper lips on piston
Inventor: THOMSSEN THOMAS UWE
IPC: F02B53/04
Filed: 1979-09-05
Abstract: The engine has a circular piston (2) which has radially projecting lobes. The lobes oscillate in circular sectors (3) in the cylinder (1a). A crank mechanism (4) controls the movement of the piston. An oil pump (8) in the sump (7) delivers oil through pipes (9) into the sectors (3) where it lubricates the surface of the piston lobes sliding in the sector. Slots (5) in the cylinder sectors open into channels (6) which take the oil back to the sump. The piston lobes have circumferential lips which push oil towards the slots but do not travel far enough to cover the slots. The oil delivery pipes (9) enter through the same slots (5).

Patent DE-3010640-A1 (DE)
Title: Electrode wire feeder for welding machine - where oscillating twist is superimposed on axial motion of wire to overcome any resistance to travel of wire to burner
Inventor: HAFNER JOSEF
IPC: B23K9/133
Filed: 1980-03-20
Abstract: The wire is uncoiled from a drum or spool, and travels, between a pair of feed rollers, at least one of which is driven. After leaving the feed rollers, the wire is provided with an oscillating rotary motion, superimposed on its axial motion by a rotating chuck in frictional contact with the wire. The chuck pref. contains two rollers which can be moved radially towards the wire by adjusting screws fitted with springs pressing the rollers against the wire. The rollers twist the wire by frictional contact until the torsion created in the wire restores the wire to its initial, untwisted position; this cycle is then repeated. From the feeder, the wire travels through a relatively long flexible hose which contains pipes, supply cables etc., so an appreciable resistance to the travel of the wire is created. The invention overcomes this resistance by simple, inexpensive means, so the wire travels to the burner without difficulty.

Title: Pre-twist flyer - with bobbins around flyer axis to reduce ballooning length to give more compact assembly
Inventor: RUF JOSEF
IPC: D07B3/00
Filed: 1980-07-30
Abstract: The axes of the bobbins lie parallel to the flyer axis on the pre-twist flyer. The bobbins are arranged at intervals on a circumference around the flyer axis. Specifically the flyer axes are aligned at least close to the vertical. A number of bobbins are located round the bobbins on the axis of the flyer which is arranged axially to each other on the axis. An axially parallel tube can guide the filament material to the flyer, with a length matching the length of the axial bobbins to be rotated round the flyer axis by radial arms. An additional radial arm between the axial bobbins, gives extra support to the guide tube. The layout reduces the ballooning length of the filament material passing to the cable twisting point, as it only moves along the axial length of the bobbin. This gives the whole unit a more compact form.

Title: Visual learning organ - has cassette controlled microprocessor to display optically which keys to press
Inventor: SCHADT DIETER
IPC: G10H1/00
Filed: 1980-10-23
Abstract: The organ is equipped with a microprocessor which is fed from interchangeable cassettes, indicating to the player, by an optical signal, which keys he has to press. After depressing the designated keys, the light signal is extinguished and the signal for the next keys to be played is illuminated. With this type of organ, anyone is able immediately to operate the correct keys, without knowledge of the notes - making it possible even for children to play. The light system can be adapted for various musical instruments such as piano, accordion, harmonium etc., the advantage being that the computer is programmed to select the keys to be pressed, and a tune can therefore be learnt in the shortest possible time.

Title: Vehicle electrical system diagnostic unit - reduces noise by operating independently of supply, and contains window comparator, logic and display
Inventor: MAYER GERHARD
IPC: F02P17/00
Filed: 1980-11-15
Abstract: An arrangement for testing electrical systems in vehicles with a current measurement probe requires fewer connections than conventional systems and eliminates the previously necessary connection to the electrical supply. Ignition transients are thus reduced and the operating reliability improved, in partic. for digital and computer-controlled systems. A voltage proportional to the measurement current is used to determine the condition of the electrical system. The voltage is displayed on an oscillograph or recorder showing the peak and/or average value. The voltage is also input to a window comparator with variable upper and lower limits. The comparator output is fed to evaluation logic which drives an analogue or digital display and controls the comparator.

Title: Disposable hollow needle fixed to plastics base - by eddy current heating combined with radial expansion of needle tube
Inventor: HOLZWARTH FRIEDRICH
IPC: B29C65/46
Filed: 1980-12-02
Abstract: The Parent patent described a disposable hollow needle in which a metallic needle tube projecting out from a central bore in a thermoplastics base is fixed in that base by melting the thermoplastics materials by eddy current heating. In this addition, the metal needle tube is widened out, esp. at its rear end, inside the bore of the thermoplastic base, so that it bears axially in both directions against material of this base. The inner end of the metal tube may be expanded to cylindrical form , tapering or conical form, or the locked in portion may be formed as a beading. Used as a needle intended for once-only use with a hypodermic syringe. The physical locking-in of the needle tube to its plastics base provides very strong resistance against pulling out.
