Title: Gear change mechanism for motor cycles - has pivoting lever operating two independent spring loaded change mechanisms
Inventor: STEUER WERNER
IPC: B62M25/04
Filed: 1975-12-12
Abstract: The gear change has a single pivoting change lever with support and connecting link to the change mechanism. There is a housing, an indicator and a method of fixing to the motor cycle frame. The change system can by simple adjustment be used for a variety of gear layouts. The change lever (1) pivots on a baseplate mounting and activates two independent change mechanisms. The lever operates a control plate (9) which moves on the baseplate (5) and has two control elements with profiled surfaces (14,15) and adjusting elements (16). Transmission shafts (23,24) are attached to the profiled surfaces. One of the shafts is spring loaded. An alternative layout has a direct operation for one of the change mechanisms.

Title: Acoustic warning signal for fishing rod - has sprung clamp on handle with bell and spring
Inventor: KUNICKE WERNER
IPC: A01K97/12
Filed: 1976-02-21
Abstract: The indicator is for warning when a fish has a bitten and consists of a sprung clamp (2) inserted onto the handle. The fishing line is hung in a groove on a bell (1), and when the fishing is being carried out in strong-flowing currents, the line is looped before being hung in the groove. The fishing line is coated with a soft rubber tubing so that it does not get entangled in the bell spring (7). When the fish pulls at the fishing line, the bell is set in motion and hits a metal piece to give a single acoustic signal.

Title: Adhesive distributor for travelling strip - has set of slope and height adjustable troughs between adhesive container and conveyor
Inventor: DREER GOTTFRIED
IPC: B05C5/00
Filed: 1976-07-14
Abstract: The unit is for applying a layer of adhesive to a travelling strip of material e.g. plastics. A horizontal belt conveyor (17) for the material (3) and an adhesive container (7) above distributes the adhesive onto a trough shaped downwardly sloping guide (4). This can swing about a horizontal axis (15) at the feed and can be raised or lowered (B) at this end to alter its angle and the height of fall of the adhesive. An extension (10) slopes at a steeper angle, which can also be adjusted and allows the adhesive to fall onto another sloping trough (12) with a final adjustable swinging extension (10'). Both troughs may be heated, and can be adjusted longitudinally. After falling from the final extension (10') the adhesive can pass under spreader rollers (18, 18').

Title: Operating technique for piezoelectric powered printing head - provides voltage pulse to accelerate drive element for matrix printer in return direction
Inventor: HEIDER ULRICH DR ING
IPC: B41J9/26
Filed: 1976-07-23
Abstract: A piezoelectric powered matrix printing head is operated in such a way that a high printing speed together with a high impression force are achieved simultaneously. After the recording surface (A) has been struck a renewed electrical voltage impulse is applied to accelerate the piezoelectric driven element (E) in the reverse direction. This impulse is applied by the control unit after a shock wave running time corresponding to the quotient of the length of the drive element (E) and the propagation velocity of the shock wave induced in the drive element whent he recording surface is struck. During the flight phase (4) of the drive element up to the its return to the initial position, the drive element is held by the control in an extended condition.

Title: Plant growth regulators esp. for seeds - contg. sodium and/or potassium bi:sulphate, bi:sulphite, dithionite and/or sulphate
IPC: A01N59/02
Filed: 1976-10-14
Abstract: Plant growth regulators contain as active ingredient sodium and/or potassium bisulphate, bisulphate, dithionite and/or sulphate, opt. together with carrier materials, extenders, diluents and/or adjuvants. The salts exert plant growth regulant activity and substantially increase the germination power of seeds and the green weight and yield of plants. Principle effects on plants are the promotion of growth and the acceleration of flowering and fruit repening. The increase is germination power gives more rapid development of stem and roots, and also permits germination at lower temp., so that sowing may be earlier. The agents can be used for regulating the growth of mono- and dicotyledonus plants, esp. maize, cereals, sunflowers, lucerne, sugar beet, rape, soya, potatoes and rice. Treatment may be pre-sowing, pre-emergence, post-emergence, or by incorporation into the soil.

Title: Cylindrical component e.g. hose union with sleeve - has one component softer than screwed sleeve which fits on harder screwed component
Inventor: LOHSIN ECKHARD
IPC: F16L33/207
Filed: 1976-12-29
Abstract: The union couples a cylindrical screwed component to a second cylindrical component coaxial to it and of the same diameter, by means of a sleeve fitting over both. The sleeve (5) is of softer material than the screwed component (7), and the second component (1) is in turn of softer material than the sleeve, which has an internal screw thread (6) where it fits over the second component. Thus the softer item in each case has a thread cut in it by the harder one. Steel can be used for the screwed component, plastic for the outside at least of the second one, and brass for the sleeve. The union can be used as a cable hose coupling.

Patent DE-2701687-A1 (DE)
Title: Automobile gas turbine engine - uses magnetic pole-changing design for magnetostatic compression of hot gas against combustion chamber core axis
Inventor: STROBEL CHRISTIAN DIPL ING
IPC: F02C3/00
Filed: 1977-01-17
Abstract: The automobile gas turbine with magnetostatic compression and hot gas flow in the combustion chamber uses a magnetohydrodynamic (MHD) voltage converter. The combustion chamber outside the shielding has a magnetic pole-changing design. Within the combustion chamber, however, no current output collectors are provided, and the hot combustion gases flow at high velocity through the combustion chamber and nozzle constriction. Magnetostatic compression of the hot gas against the core axis of the combustion chamber and nozzle throat follows from the alternating action between the surrounding pole-changing magnetic field and the velocity-related natural magnetic field of the free charges, resulting from ionisation, that are carried by the gas. This compression gives rise to an increase in the combustion chamber pressure whose energy requirement is derived from kinetic gas energy and leads to contact-free hot gas condition in the chamber and nozzle constriction.

Title: Supply and measuring installation for needle shaped objects - has sloping vibratory lower frame unit and distribution installation
Inventor: NOREN JOHN
IPC: B65G47/19

Title: Coil of metal foil made continuously - by vacuum vapour deposition, where each metal layer is sepd. by antiadhesion layer
Inventor: SCHEVAKIN JURIJ FEDOROVITSCH
IPC: C23C14/56
Filed: 1977-05-25
Abstract: Rolls of metal foil (b) are made by continuous vacuum vapour deposition, where a rotating drum is coated with an anti-adhesion layer (a) onto which metal (b) is condensed. With the continuous rotation of the drum, the deposition sequence a,b,a,b,a,b,... is repeated, i.e. after each metal layer (b) is deposited another layer (a) is applied before the next layer (b). A roll or coil of metal foil is thus obtd. in which each turn of metal (b) is sepd. by a layer (a). Used esp. for the mfr. of pure metal foil with high quality and rapid prodn. An example is Al foil for the mfr. of Al electrolytic capacitors, where an exact microsurface is produced on the foil, improving the forming during capacitor mfr. and therefore the quality of the capacitors.
