Title: Rolling bearing
Inventor: STAUDT HEINRICH DIPL ING
IPC: F16C43/04
Filed: 1987-12-10
Abstract: The rolling bodies (3) of the bearing roll on raceways (4) which are formed by barrel rings (5).

Title: Motor vehicle with an automatic change-over for two internal-combustion engines of equal power
Inventor: HAGIN FAUST DIPL ING
IPC: B60W30/18
Filed: 1987-12-10
Abstract: A motor vehicle, especially overland or travel bus or long-distance heavy-goods vehicle, which has two internal-combustion engines of equal power as a drive source, is proposed. These each transmit their power to an axle drive train via a shift coupling as well as a summing gear and a shift or automatic gear. The total power of the two engines (1, 2) is set according to the maximum power requirement of the motor vehicle. The two engines are operated jointly during starting and acceleration or on mountain trips. Only one engine is in operation on trips at a constant level or in valleys. In order to achieve a long lifetime and essentially identical power collectives for the two engines, there is provided an automatic change-over (20) which, in dependence on and after the detection of a specific number of starting and/or accelerating and/or braking operations and/or the operating period of an engine operated alone and/or other operating processes of the vehicle, activates the other particular engine as the vehicle drive for the subsequent single-engine operating phase or phases the value of which is to be detected.
Patent DE-3743047-A1 (DE)
Title: Automatically working large-channel annular valves for Otto engines
Inventor: SCHWARZ HELMUT
IPC: F01L3/20
Filed: 1987-12-18
Abstract: What is presented is a fully automatically working large-channel annular-valve supply for Otto engines, which utilises the suction of the piston during the downstroke both for the automatic opening of the intake valve and for the closing of the outlet valve. Whereas, during the upstroke of the piston, the opposite conditions take effect, namely the inlet valve closes, but in contrast the outlet valve opens in order to eject the used gases. The valves utilise, specifically over the entire surface, the total circumference of the piston head, thereby guaranteeing a sufficient passage of the activated gases for the breathing of the engine. Whilst the inlet valve works fully automatically, the outlet valve requires a control aid in the form of a bolt which closes the outlet in the working position of the piston and in the intake and compression phase and which keeps the valve open only during the ejection of the used gases.

Patent DE-3804860-A1 (DE)
Inventor: ROTHSTEIN HANS WERNER
IPC: E04C5/18
Filed: 1988-02-17
Abstract: An electrically operated hand hair drier (10) has a housing (11, 12) with an inlet (13) at one end, an outlet (36) at the other end and a hollow handle (23) extending at an angle relative to the housing. In the housing (11, 12) is an electric motor (18) for driving an impeller (22) and air heating means (16) which can be operated in a plurality of output stages by means of a switching device (41). The output stages can be individually switched. A shaping nozzle (14) is releasably secured, for example by a push-on connection, to the walls delimiting the outlet (36). So that excessive heating is prevented, at least one of the multiple output stages of the switching device (41) is put into a switched-off condition, by fitting the shaping nozzle (14) which causes axial sliding movement of a switching bar (38) to open a pair of contacts (40, 50) connected to the switching device (41). <IMAGE>

Patent DE-3833655-A1 (DE)
Title: Carrying aid
Inventor: EBNER FRANZ
IPC: A45F5/00
Filed: 1988-10-04
Abstract: The carrying aid prevents cutting and sweating of the hands and slipping of the load. The invention relates to a piece of leather (rubber, synthetic material) which protects the palm of the hand from injury when carrying loads with sharp edges which cut into the hand. In order that this piece of leather (rubber, synthetic material) stays in position, it is bound around the outside of the hand with three wide straps or is held by means of four loops (one for each finger) which run over the fingers, the thumb remaining free. With a commercially available protector, such as a glove, the person carrying the load sweats and the load slips since there is no gripping ability. This is not the case with the carrying aid since only the palm of the hand is covered. The back of the hand and the fingertips are completely exposed which guarantees a firm gripping ability for heavy loads.

Title: Vibration-free gas refrigerating machine according to the Stirling principle
IPC: F25B9/14
Filed: 1988-10-30
Abstract: Vibration-free gas refrigerating machine according to the Stirling principle, two identical machines, the pistons of which are arranged on the same geometrical axis, being operated in such a manner that their working cycles are offset temporally in relation to one another by half a cycle and consequently the mechanical vibration generated by each of the two machines being neutralised in its effect. The drive of the two gas refrigerating machines is carried out in each case by an electronically switched tandem linear drive, as a result of which only mechanical and dynamic moments arise in a single geometrical axis in the entire apparatus, which moments are neutralised at any time as a result of their phase position of 180@ and their equal amounts. The four pistons of the two refrigerating machines are arranged coaxially and point in one direction so that the effect of both cold places is increased. The apparatus according to the invention is, in its preferred embodiment, always an at least two-stage gas refrigerating machine.
