Title: Contactless icing control system for refrigerators - uses photoelectric system with light beam directed over icing area
Inventor: SCHOENEICH GERHARD
IPC: F25D21/02
Filed: 1976-01-26
Abstract: Icing control system is used espec. in air conditioning plants and in refrigerators, and system ensures that deicing heater is switched on when ice is formed or when ice is formed, or when ice layer thickness exceeds a certain value. The control system uses a photoelectric arrangement in which beam of light such as infrared light beams is directed on a reservoir. The light path covers the icing area and it is interrupted by ice. When this happens then the deicer is connected. The photoelectric system is mounted in fittings made from material which is not readily distorted over the temperature range used. The light emitter can be a luminescene diode with a lens and the receiver is a phototransistor tuned to emitter.

Title: Seal between concentric tubes - comprises resilient ring tilted into sealing engagement by sliding tubes together axially
Inventor: WOLF FRANZ-JOSEF
IPC: F16L17/035
Filed: 1976-04-05
Abstract: Seal between an inner (1) and an outer tube (16) comprises a resilient ring seated in a groove in the outer surface of the inner groove. When the outer tube is slid axially on to the inner tube, the leading end of the outer tube abuts a radially outwardly extending flange (8) of the ring. This tilts the ring toroidally about its seating in the groove and causes an axial flange (9) of the ring section to rise against the outer tube. The two flanges then lie flattened against the inner diameter of the outer tube and effect a seal.

Title: Two pole rotor for sync. machine - has laminated core and central permanent magnet to provide about half useful total flux
Inventor: ZALMANOV GEORGIJ ARONOVITSCH
IPC: H02K3/20
Filed: 1976-08-05
Abstract: Small machines for autonomous local power supplies have a construction which is intended to give better utilisation of the rotor material. The core is constructed of single piece laminations (1) held together by axial bolts (8) between solid endplates. The laminations have recesses to carry the excitation winding (5) and the endplates have corresp. slots in the face abutting the laminations. In the centre of the core is a space into which the permanent magnet (11) fits. The endplates also carry stub shafts for the rotor. The clamping bolts (8) also act as damping windings, and the material for them may be chosen with this duty in mind. the permanent magnets typically provide 50% of the useful flux thus permitting reliable self excitation of the machine.

Title: Valve spindle movement duration adjusting mechanism - uses liq. damping medium forced through throttle by movement of pneumatically operated piston
Inventor: MIETH HANS-OTTO DIPL ING
IPC: F16K47/02
Filed: 1976-08-26
Abstract: The mechanism adjusts the duration of the valve spindle movement in a pneumatically-operated pipe junction or shutter, having a closed ram cylinder fitted to the junction or shutter housing. This is so arranged that the return forces generated by movement of the piston resulting from the pressure of the operating medium either shut or open the shutter. Bars with axial drillings are connected top opposite sides of the piston and deliver the gaseous operating medium to it. A damping medium, pref. liq., is accommodated inside or outside the cylinder and movement of the piston forces it through a throttle. The piston can be thrust into the rest position by a return spring and a vessel accommodating the damping medium can be provided.

Title: Rolling mill for wide metal strip - using gas cushions in hydraulic pistons which prestress work roll chocks (NL 12.5.77)
Inventor: HOORNSTRA SIMON
IPC: F15B15/14
Filed: 1976-11-09
Abstract: Bearing device, esp. for a wide strip rolling mill, where the ends of the work rolls are located via bearings in chocks.

Patent DE-2714334-A1 (DE)
Title: Torque indicator for threaded nut - has wire coil on exterior with end gap increasing with nut expansion caused by increased torque
Inventor: KEYLWERT JOHANN DIPL ING
IPC: F16B31/02
Filed: 1977-03-31
Abstract: The radial expansion of a nut is proportional to the tension it produces on a bolt on installation. In order to monitor the expansion of the nut and thus the bolt tension, a thin wire is coiled around the outside of the nut. One end of the wire coil is fixed, whilst the other end is free. When the nut is installed, the resulting radial expansion causes the wire coil diameter to increase. The free wire end therefore moves away from its rest position and the distance it moves is directly proportional to the induced bolt tension and can be graduated as such on the nut surface.
