Title: Refrigerated display container
Inventor: ABRAHAM FAYEZ F
IPC: F25D17/08
Filed: 1981-01-31
Abstract: Extending around the housing of a refrigerated display container are a first air pipe and, on the outside thereof a second air pipe which has an outlet opening which is adjacent to the outlet opening of the first air pipe. During the refrigeration cycle, partially refrigerated air is conducted transversely over the outlet opening of the housing outside the air which has emerged from the first air pipe. The inlet opening of the second air pipe is arranged such that part of the circulated air passes directly into the second air pipe and that the rest of this air passes over some of the evaporator coils before it enters into the second air pipe. During defrosting, ambient air is taken in through the outlet opening on the first and the second air pipes and circulated through the first and second air pipes in a reversed direction, in which case it transfers heat to the air in the first air pipe due to conduction and convection. <IMAGE>

Title: Sporting device for determining impact energy
Inventor: TAEUMER WOLFGANG
IPC: A63B69/00
Filed: 1981-02-24
Abstract: The invention relates to a sporting device for demonstrating impact energy, such as for example a karate board. Conventional karate boards consist of wood and can be used only once. According to the invention, board sections consisting, preferably, of plastic are joined together by means of connecting elements at the point of separation to form a karate board. Under the action of impact, the connecting elements are destroyed, the number of connecting elements used or their strength properties being capable of serving as a measure for the competitive determination of achieved impact energy. By replacing the destroyed connecting elements with new ones, the same karate board can be used as often as desired.

Title: Method for monitoring the flow relationships of a liquid metal
Inventor: NAKAMOTO KOICHIRO
IPC: G01F1/00
Filed: 1981-04-30
Abstract: Method for monitoring the flow relationships of a liquid metal, using a detector which consists of an excitation winding which is supplied with an alternating current, and at least two detector windings which are arranged on both sides of the excitation winding. The detector is situated in the direction of flow of the liquid metal. The peak point of the cross-correlation function of the fluctuation signals in the detector windings is checked. By recording the direction of movement, the polarity and the level of the peak point, it is possible to determine the flow relationships, for example a change in the rate of flow, a change in the steam bubble content, the presence of steam bubbles and the rate of migration of the steam bubbles. <IMAGE>

Title: Process for producing a rim for vehicle wheels, in particular motor-vehicle wheels, and rim produced by the process
Inventor: SCHWARZ GUENTER
IPC: B60B5/02

Abstract: The invention relates to a process for producing a rim with tyre-bearing surfaces for vehicle wheels, in particular motor-vehicle wheels, in the case of which process a blank consisting of an aluminium alloy is brought into the end form by diameter turning and is then coated with a synthetic resin layer. In order that the resulting rims have sufficient hardness, wear resistance and abrasion resistance in the region of the tyre-bearing surfaces, the invention provides that, in the region of the tyre-bearing surfaces, the synthetic resin layer is removed by turning, and that hard-coat layers are applied to the re-exposed tyre-bearing surfaces in a galvanic bath.

Title: Process for gas-nitriding workpieces of metals and alloys
Inventor: GRACEV KONSTANTIN ANDREEVIC
IPC: C23C8/26
Filed: 1981-07-29
Abstract: The process for gas-nitriding workpieces of metals and alloys comprises heating the workpieces to the saturation temperature of the metals and alloys. After the temperature corresponding to the starting temperature of the dissociation of the saturating agent with formation of active nitrogen has been reached, a direct magnetic field is generated in the working space and crossed by an alternating magnetic field of technical frequency. Subsequently, the workpieces are held at this temperature and cooled to a temperature which corresponds to the temperature of the completion of the transformations in the iron/ nitrogen/carbon system. The action of the magnetic fields is then switched off and cooling of the workpieces is continued.

The composite labelling tape is of the type in which a pressure-sensitive adhesive is applied to the underside of the label and the outside of the label has no adhesive and can be printed with price change details. The label can however be applied by means of a hand labelling device to the underside of a tag, and then the label is folded by hand, so that the printed price change data are visible on the same side as the printed price data on the outside of the tag. The invention further comprises the combination created thereby of price tag and price change label, and a method for recording and changing prices making use of such labels.
Patent DE-3206837-A1 (DE)
Inventor: KNOEDEL GUNTER ING GRAD
IPC: F16F15/12
Filed: 1982-02-26
Abstract: In an arrangement embracing an internal combustion engine and transmission, intended in particular for use in motor vehicles, the crankshaft is split on the side of the flywheel (6) facing the engine and the crankshaft sections are interconnected via a torsionally elastic intermediate member (9). The crankshaft section (5) carrying the flywheel (6) may be seated in a bearing (4) disposed in an intermediate flange rigidly connected with the transmission housing (1). Further, the housings (1, 2) of the engine and the transmission may also be connected via elastic elements (31). This arrangement of torsionally elastic elements reduces considerably the transmission of torsional forces to the transmission and makes it possible to substantially reduce the idling speeds of motor vehicles and to put up with the torsional vibrations thereby created because they are no longer transmitted to the transmission and do not, consequently, give rise to noises which are transmitted to the car body through the transmission, its housing and other components of the drive train.
