Patent DE-2530586-A1 (DE)
Title: Open end spinning aggregate with horizontal turbine axis - having driven guide roller turning thread to vertical running
Inventor: NEUHAUS LUDWIG
IPC: D01H4/08
Filed: 1975-07-09
Abstract: An open end spinning aggregate with a thread take off arrangement positioned outside the axis of the spinning turbine, has, between the turbine and the draft rollers a guide roller for the thread. The axis of rotation of the guide roller is at a distance from the axis of the turbine equal to the radius of the roller times one, and the guide roller is driven separately, forming part of the measuring head of a thread detector. Whilst maintaining the advantages of horizontal alignment of the spinning rotor such as ease of cleaning, the arrangement keepts the increase in tension due to the turning of the thread into the vertical, down to the minimum.

Title: Wide tolerance elastic seal ring - has steel band with crimped ends held loosely in annular channel
Inventor: WOLF FRANZ JOSEF
IPC: E02D29/12
Filed: 1975-10-21
Abstract: The seal ring incorporates a tolerance adjusting rubber strip with steel ring inserts. This compensates for tangential expansion of the ring and for deviations from manufacturing sizes. The steel rings are free to move tangentially and the rubber ring deforms axially and radially to accommodate expansion. The overlapped ends of the steel band (2) are clamped in a locking strip (3) of crimped C-shaped section inside the annular channel (8) in the rubber ring (1). There is a slit (9) around the inner circumference of the rubber ring (1) for insertion of the steel band and crimping strip (3). The slit is glued together after band insertion.

Title: Combined parachute pack and pilot chute - uses air scoops on pack to produce retardation for main chute extraction
Inventor: MUENSCHER DIETER ING GRAD
IPC: B64D17/54
Filed: 1975-11-26
Abstract: The parachute pack functions also as a pilot chute and consists of a cylindrical sleeve (2) open at the bottom (4) for insertion and extraction of the parachute. Over the top (6) of the cylinder, which may be closed or left open, there runs a width of material which forms projecting scoops (10) on either side. Darts (12) in the top part of the material angle the scoops inwards and the width is tapered so that the edges of the scoops run approx. vertically to about halfway down the pack where the material is sewn onto it (16). The scoop material may also be sewn to the top of the pack if it is desired to transmit the pull due to the scoop air resistance to that part. The free edges (20) of the scoops may be stiffened. A number of the cylindrical packs may be joined together in parallel.

Title: Model aircraft aileron operation - uses lost motion mechanism to operate ailerons singly, avoiding turning effect
Inventor: ZEH FRIEDRICH
IPC: A63H27/20
Filed: 1976-03-01
Abstract: The aircraft aileron operating device, esp. for model aircraft, comprises a (double) base board (1) with L-shaped guide slots (2, 3) for the aileron actuating pins (12, 13) and a pivot (4) for the actuating lever (5). Pivoted (11) idler arms (9, 10) connect actuating lever and pins; bell-crank levers (14) with forked ends (17) engaging the pins convert pin movement into aileron movement. The pivots (15) for these levers are on an extension of the line (C-C) through the actuating pins in the neutral position; one leg of the guide slots lies along the same line. A conventional input arm (7) engages with the actuating lever. When this moves from the neutral position the shape of the guide slots will cause one actuating pin to move out of the line joining the bell crank lever pivots, rotating its lever. The other will remain in that line keeping its lever steady. The turning moment produced by the two ailerons acting together ("aileron secondary effect") is eliminated.

Patent DE-2618873-A1 (DE)
Title: Roll contact head of high tension isolator - has aluminium contact tracks with silver plated copper coating
Inventor: BUENGER GUSTAV
IPC: H01H1/16
Filed: 1976-04-29
Abstract: A rotary isolator for high tension with aluminium conductors and a roll contact in the post-type insulator heads uses aluminium for the contact track of the rolling contact connection as well. To dissipate the heat produced by high current densities during overloads or short-circuits, the aluminium contact track is equipped with a heat dissipation layer of better heat conductivity (silver plated copper). This prevents any recrystallisation of the aluminium material, yet it permits all conductive parts of the high tension isolator to be made of the less expensive aluminium.

Title: Ballistic shell with vanes for stabilising flight path - gives greater accuracy whilst dispensing with rifled gun barrel bore
IPC: F42B10/20
Filed: 1977-05-13
Abstract: The ballistic shell follows a flight path accurately without spiralling, so that the energy otherwise required to propel it along the rifling of the barrel is saved. This also reduces the wear of the gun barrel. More accurate stabilising is ensured by means of vanes housed before firing in guide slots in the shell, and ejected by the gases of combustion as the projectile leaves the barrel. The vanes have inclined sliding surfaces which run as the move across the sliding surfaces of the guides and slots, as they are pressed by the gases passing along a bore through circumferential holes backwards and outwards. Ribs which are retained in the narrow slots prevent the escape of the vanes which are aligned in the slots of a plug.
