Title: Pressure relief valve for IC engine crankcase - has oil separator of centrifugal type with drain back to sump.
Inventor: GOBIEN ERNST
IPC: F01M13/04
Filed: 1978-06-28
Abstract: An excess pressure valve in the crankcase admits air into an oil separator (15). It enters the separator from above and flow through an annular oil filter (19) to a separating chamber (14). The air reveses direction and flows up an internal annular passage (18) inside the oil filter at the top of which it reverses direction again and flows down a central tube (22). This tube takes it back into the engine suction manifold. Oil remaining in the air after it has passed the filter drops out at the first reversal of direction and collects in the chamber. It is drained (17) back from this to the sump.

Title: Candle with moving wick - has metal wick holder with turned over rim in central bore of wax cylinder
Inventor: STOFF WERNER
IPC: C11C5/00
Filed: 1979-03-12
Abstract: Candle with a wick which is not solidly embedded along the centre of the wax cylinder has instead a central bore in which a wick holder can slide. The wick holder fixes a short wick in a cylindrical metal part and has a turned-over top rim which rests on the solid wax. As the wick holder rim becomes warm, it sinks into the wax. A self-regulating feature is achieved because too deep a drop reduces the flame height so that the heat developed is less and the sinking rate is slowed down. Candle needs no manual adjustment and is always ready for rekindling.

Title: Improved wear grip link for snowchain - has thickening additions to grip edges without increasing height of grips
Inventor: WALENTA GOTTFRIED DIPL ING
IPC: B60C27/08
Filed: 1979-06-18

Title: Driving cabin for mobile crane or earthmover - which is impenetrable by rain-water when front window is opened
Inventor: BOPP GUSTAV
IPC: B62D33/06
Filed: 1979-08-04
Abstract: Rotary bearings are installed one on each of the long sides of the front window of the driver's cabin in a vehicle such as a mobile crane or an earthmover. The window fits rubber seals in the front wall of the cabin and can be tilted on self-lubricating, synthetic, esp. PVC journals on an axis parallel to the transverse axis of the vehicle. Along the top edge of the window, a water-guiding rail diverts rainwater sideways, and between it and the structure when the front window is closed, and when it is open, a tight joint is formed by a rubber seal. For the sealing of the other window edges, the rubber seal is fitted to a window rim projecting at right angles to the front wall. When the front window is opened, no rainwater can penetrate into the cabin and improved visibility for the driver is one of the advantages.

Patent DE-2941789-A1 (DE)
Title: Power supply for electronically controlled appliance - with separate connection between smoothing capacitor and memory unit to maintain supply to memory of washing machine
Inventor: SCHOTTEN HENNO DIPL ING
IPC: D06F39/00
Filed: 1979-10-16
Abstract: Some domestic machines employ control systems with memory units as part of the sequencing control. If there is a supply interruption the memory contents is lost and the process may have to start again from the beginning. The electronic power supply is derived from a bridge rectifier (G1) connected to the secondary winding of a mains transformer (Tr). The rectifier output is smoothed by a large capacitor (C), and voltage regulated by a transistor (T1) in the positive lead. The control signal from a zener diode (Z) connected to the negative lead operates on this transistor. A second transistor (T2) is added to the negative lead. If there is a supply interruption this transistor turns off thereby cutting off the supply to the electronic circuits. The memory negative terminal is connected directly to the negative of the rectifier and capacitor. Thus a power supply remains on the memory during a mains interruption for as long as there is sufficient charge in the capacitor (C).
Patent DE-2950812-A1 (DE)
Title: Force transducer with load compensation - ensures uniform load distribution by using plastically deformable synthetic, soft metal, or rubber element
Inventor: BROSA ERICH
IPC: G01L1/26
Filed: 1979-12-17
Abstract: The load compensation arrangement is for a force transducer and ensures a uniform distribution of the load on the transducer, even when the components of the load are uneven or not parallel. Edge loadings are transferred more satisfactorily than with conventional steel caps. The hard upper section (4) of a force transfer component is filled with a plastically deformable synthetic or a soft metal cap (3), which adapts accurately to the radius (6) of the force cell (2) under load. Threaded grooves (5) prevent the cap material from being squeezed out. An alternative arrangement uses a relatively thick rubber plate inside a hard upper section which compensates for load surfaces being out of parallel by flaring. The upper section has concentric grooves into which the plate material flow is confined.
Patent DE-2952562-A1 (DE)
Title: Junction straps for structural joint sealing foils - made of PVC, carbon black and chalk as negative replica
IPC: E04B1/68
Filed: 1979-12-28
Abstract: Foils, made of soft PVC or rubber and used in the building industry to seal joints between concrete structural parts, must be joined by a perfect butt joint which must ensure tightness against liquid and gaseous media. This is achieved by using two straps which form an exact negative replica of the surface of the sealing foil and stand out beyond the width at both sides. The prefd. material for the straps is a mixture of PVC, carbon black and chalk which is extruded and stored on a drum, marked for cutting up and applying an adhesive. These straps are easy to produce and ensure a reliable seal.

Patent DE-3027532-A1 (DE)
Title: Electronic ignition angle control for I.C. engine - has knocking sensor whose output in one speed band is used for correction over whole engine speed range
Inventor: GEIGER ISTVAN DIPL ING
IPC: F02P5/152
Filed: 1980-07-19
Abstract: The ignition angle controller with feedback from a knocking detector is intended to overcome the problem of indeterminable signals from the detector at certain times, normally at high engine speeds. The equipment contains an ignition angle computer (30) for evaluating a modifying angle (delta alpha Z) which, when added to the basic angle (alpha Zo) gives the required angle (alpha Z) for engine operation without knocking. The knocking detector output (34) is evaluated at one speed, and this result used to modify the ignition characteristics over the whole engine speed range. The computer may store a series of ignition characteristics and use the knocking signal to select the most appropriate. Alternatively it may compute a characteristic by interpolation between two programmed limiting curves. The other signals used typically include engine temperature, speed, manifold depression, and load.
