Title: Pipe connector for tubular structure - has locking block secured in tube by bolt, with rocking action, wedging inside second tube
IPC: F16B7/04
Filed: 1979-12-17
Abstract: The fitting connecting the ends of two tubes enables structures such as exhibition stands, shelving etc. to be built up. This fitting uses an adaptor sleeve (1) which fits between the ends of the two tubes (20) to be connected, with a shoulder (2) at each end of a cylindrical part (3) matching the external size of the tubes. Into the remaining projecting part (9) which is fitted inside the tube end, is secured by a nut (13) and bolt (4), a wedge block (10). This block has a curved end which fits into a troughed recess (8) in the adaptor, and which holds the nut, and which is locked in place when the bolt is inserted. The other end is serrated (11) to lock inside the second tube end. The block has central ridge (12) forming a pivot point when the bolt is screwed in, ensuring a strong connection at the serrated zone.

Title: Thermoplastic carburettor float - having two hemispheres with tapered edges which are welded together under constraint to prevent distortion elsewhere
Inventor: KALLINOWSKY HANS
IPC: B29C65/00
Filed: 1980-02-25
Abstract: A plastic carburettor float in two halves, one having a joint, is produced with their mating edges tapered; they are welded together by heating the edges by a hot plate but without contact, and joining them so that only the tapered edges fuse together at their softened areas. Each half of the float rests in an impression in a plate, and they are positioned opposite each other and their edges are tapered. The plates can move in their mounting blocks which have moving pressure members. Rejection rate is minimally low, so permitting mass production, only the edges are softened so that no dangerous stresses arise elsewhere.

Title: Winding apparatus for CRT deflection coils - uses hollow trumpet shaped former with grooves and channels, rotated between winding devices
Inventor: HOFFMANN BERND
IPC: H01J9/236
Filed: 1980-03-25
Abstract: The method of forming both the horizontal and vertical deflection coils for a CRT uses a trumpet shaped former with two small flanges at one end and three larger flanges at the other end. These flanges form two grooves (4,5) at the smaller end and two grooves (6,7) at the larger end. The former is supported large end downwards and rotated between an arrangement of coil forming devices so that the wires can be passed around these grooves and also through a set of channels down the interior, following the curvature of the walls of the former. The coil forming devices include a feed tube (10) through which the wire (20) is passed, and which can travel across the open mouth at the bottom, travelling across its flared face, and upwards into the interior. Adjacent to the upper grooves (4,5) are hooked rods (12,13) which engage the inserted wire to form loops which are pulled outwards for guiding into the respective grooves.

Title: IC engine with two cylinder sets - has torsional vibration damper on full load section of crankshaft
Inventor: WILLMANN MICHAEL ING GRAD
IPC: F16D25/0635
Filed: 1980-07-05

Title: Person or load lowering device - has load bearing eyelet with friction braking web slidingly seated in two sloping slots
Inventor: LUTAT ERICH
IPC: A62B1/14
Filed: 1980-10-06
Abstract: The person/load lowering device travels on webbing suspended at its end from a fixed point in the building. The mechanism is fitted in housing of a box cross section, with a base carrying the webbing. On top of the webbing, a brake plate is provided, with the web of the load-bearing eyelet exerting pressure on the plate and consequently on the webbing when the load is fitted to the eyelet, causing it to slide downwards on the sloping slot with resulting friction between the plate, webbing and housing base.

Title: Wind-driven power station
Inventor: BEINHOFER ARTHUR
IPC: F03D3/02
Filed: 1981-02-24
Abstract: The present invention relates to a wind-driven power station for producing electrical current and heat from wind energy. Instead of employing a horizontal axis of rotation of the wind wheel as in the prior art, the axis of rotation is, according to the invention, positioned vertically and a multiplicity of wind wheels coupled in each case to one or more generators are arranged one on top of the other. This results in the possibility of being able to use winds from different directions even at different heights equally well, an additional advantage being a particularly small base area.
