Title: Seat belt slotted mounting plate - has asymmetric form to avoid bunching of belt in slot upon tightening
Inventor: PFANNES GUENTHER DIPL PHYS
IPC: B60R22/24
Filed: 1974-06-14
Abstract: The plate (1) leads the seat belt from behind the seat over the wearer's shoulder. In an accident, the end passing over the wearer's should is at first in more tension than the other. The resulting tendency of the belt (3) to slide to one end of the slot (4) and jam there, neutralized when the fixing hole (2) is positioned slightly asymmetrically. After the peak of tension is passed, the end of the belt passing over the wearer's shoulder is the less tight of the two, and the position of the fixing hole now reinforces the tendency of the belt to slide to one end of the slot. Jamming there, it rests slackly across the wearer in the now-stationary car.

Title: Yarn dyeing fluid flow control - uses a valve which changes flow channels between suction and pressure sides of one-way pump
Inventor: CHRIST WILHELM
IPC: D06B5/16
Filed: 1974-11-28
Abstract: The wound yarn packages are supported in columns in a vessel with a one-way circulating pump and a valve to reverse suction and pressure. The reverse valve has a cylindrical upper section bonded to the dyeing vessel with an inner flow aperture passing to the inner hollow zone through a carrier plate. At least one outer flow path, linking the open inner vessel zone, and a cylindrical lower part rotating coaxially between the upper part and the circulating pump connects with the pressure or suction side of the pump and >=1 axial outer flow path, according to the rotary positioning of the lower section. As the rotary section is moved alternately from one setting to the other, so the inner and outer flow channels are used for pressure and suction alternately. The design gives a simple reverse flow valve which can be installed in conventional yarn dyeing vessels, giving a rapid reversal of the flow pattern to give a symmetrical flow through the vessel.

Title: Grain sifter with vertical recirculating airstream - has auxiliary fan at entry port to keep grain airborne
Inventor: KNOLLE WILHELM PROF DR ING DR
IPC: B07B4/02
Filed: 1975-03-29
Abstract: The sifter has grain injected (12) at high speed (1m/sec) at a point about halfway along the central shaft through which a vertical airstream (3) passes. An auxiliary fan (9a) at the point of injection sustains and spreads the dense stream of grain, and the traverse across the shaft is made longer in consequence. Heavy grains fall on to a grid (16) which slopes obliquely across the vertical shaft, lighter grains become airborne and leave the shaft at the top sides, to fall again outside in the wider, low-pressure compartments. They are retained on oblique sieves while dust falls to a removable tray (20) at the bottom. Axial fans at the lower end of the outer compartments sustain the air circulation.
