Title: Retention system for laminar stator packet - fixes into stator casing using steel rails with sound absorbing layers to reduce noise
Inventor: LINK KARL DIPL ING
IPC: H02K5/24
Filed: 1978-03-15
Abstract: The retention system has retaining assemblies distributed around the stator's circumference. Each retaining assembly contains a sound damping layer (6b, 6d) that holds the laminar stator packet (1) away from the stator casing, forming a circular gap (8) in the process. The retaining assemblies are seated in recesses in the outer periphery of the laminar packet. Each retaining assembly has a steel fixing rail (6a) with threaded holes (10). Bolts pass through the stator casing and screw into these threaded holes. The advantage lies in reducing noise without reducing performance and with no sound-proof hood.

Title: Parcel wrapping machine for plastics film - has belt conveyors with welding and cutting station, controlled by optical sensors
Inventor: WEHINGER RUDOLF ING GRAD
IPC: B65B35/24
Filed: 1978-09-01
Abstract: The machine for wrapping parcels in plastics film and welding and cutting the sealed wrappers, has two belt conveyors (1, 2) on which the parcels are carried towards the wrapping station. There, a parcel is inserted in the plastics tube made by a shaping member. It then passes to another belt conveyor and the connection between parcels is sheared by an overhead welder and cutter. The parcels are then carried onwards by a final conveyor. At the junction between the first two conveyors is a photo cell which stops the first conveyor while the others continue to operate, until a parcel reaches a second photo cell at the cutter and welder. This then stops the other conveyors until the connection has been cut, and the cycle starts again.

Title: Securing buttons to fabric sections by threads - including impregnating thread with adhesive before sewing
Inventor: CONRADI GEB KIRSTOWSKI URSULA
IPC: D05B3/14
Filed: 1978-09-23
Abstract: The threads forming the loops to hold a button on to a fabric section, are bonded to the bottom threads by means of an adhesive. The threads pass through the holes of the button and loop back through the fabric, and the adhesive may be applied only to the zone of the threads on the side of the button facing the cloth. The threads may be wound round the strands of the loops to form a cord which is strengthened by adhesive, and the proposal is partic. applicable to the sewing of buttons by machine, since it prevents the easy pulling apart of top and bottom threads. The adhesive may be applied to the thread as it runs from the reel to the needle so that buttons are attached securely without hand sewing.

Title: Vacuum-forming process for plastics - in three stages of pre-stretch, side wall contact and full mould contact
Inventor: ROEVER HEINZ
IPC: B29C51/10
Filed: 1979-05-18
Abstract: A vacuum forming process of plastic trays, for example for cowls used as roof vent covers, is carried out in several stages. In the first stage, the plastified sheet of a plastic such as rigid PVC is deformed to effect a prestretch until the temp. rise of the air in the evacuated mould has been balanced. The second stage is concentrated on drawing the sheet to the peripheral areas of the mould, and in the last stage the whole mould surface is contacted by the sheet. This gives an adequate dimensional accuracy and uniformity in wall thickness and requires little extra engineering effort.

Title: Fluid media mixing device - with two cylindrical vessels for tangential entry and exit sepd. by orifice plate
Inventor: SCHAEFER HELMUT DR
IPC: B01F5/00
Filed: 1979-09-12
Abstract: A device to mix fluid media in motion without any moving parts consists of two cylindrical or polygonal vessels with a common centre line which are joined to each other by a plate with a central hole. The first vessel has a narrow tangential slot for the inflow of the two media. This creates a high-velocity circular motion. This continues at high velocity in the same direction in the second vessel as the fluids enter at the centre. They leave through a tangential slot in the second vessel. As the circular motion is decelerated in the second vessel, the kinetic energy is recovered and little energy is spent for the mixing process. No moving parts are needed so that the power consumption to generate the pressure loss is kept to a minimum.

Title: Safety system for prim. circuit esp. of boiling water reactor - has ultrasonic detector head mounted externally on pressure vessel
Inventor: STANG WOLFGANG DIPL ING
IPC: G21C17/038
Filed: 1979-11-24
Abstract: Safety system for a liq.-cooled nuclear plant, comprising reactor pressure vessel and circulating system, consists of an ultrasonic measuring device with the measuring head (emitter and receiver) acting as a vapour bubble detector for the cooling liq.; this detector is indirectly coupled to the cooling liq. by being mounted on the wall of the reactor pressure vessel and transmitting directly through this wall. System is esp. for boiling water reactors, where the core tank is surrounded by a chamber into which the recycled water flows. One detector head is mounted near the upper edge of the core, and another detector heat near the lower edge. A third detector head may be mounted near the circulating pump. Used for liq.-cooled reactor, esp. a boiler water reactor. By mounting the ultrasonic detector head outside the vessel, no penetration through the vessel is required and the system is thus considerably simplified. Moreover, it responds much more rapidly than a previous arrangement, where the ultrasonic detector head acts on the reflecting principle to detect a change in level inside the vessel. The new arrangement operates on a vapour bubble detection principle and responds much more promptly.
