Title: Circular segment rotary engine
Inventor: FAEHRMANN KURT
IPC: F02B75/02
Filed: 1984-06-26
Abstract: The invention relates to a combustion engine in which the pistons rotate about the crankshaft 17, both working pistons 4 with the piston rods 6 are firmly seated on the crankshaft 17, which forms the centre axis of the circular segment rotary engine. Working piston 4 and follower piston 5 form the swept volume. The piston force developed by the working stroke acts directly on the crankshaft 17 without loss of force. The engine comprises segmental parts: a circular segment housing 1 comprises two working pistons 4 with the follower pistons 5, the piston guide linkage 7, the centre axis pin 7a which runs in the piston guide groove 3 and controls the engine cycles. The engine is cooled by the external fan cooling and the internal cooling is effected by the intake air through the inlet slot 9, at the same time cooling the pistons and the cylinder semi-circular liner 2. The heated air escapes by way of the air exchange slot 12. The results obtained include a smooth-turning engine, minimum fuel consumption due to the rotation of the pistons with high horse power output, high compression level due to the filling weight of the intake air in the swept volume. The engine is designed for overrun cut-off and, as a result, is environmentally friendly. <IMAGE>

Title: V-belt pulley having a V-shaped groove with a matched radius
Inventor: MELZER HARALD DR ING
IPC: F16H55/49
Filed: 1984-08-16
Abstract: The invention relates to a V-belt pulley having at least one essentially V-shaped groove, the flanks of which are designed for in each case one particular V belt having a particular V angle as a function of the diameter of the V-belt pulley. The intention is to provide a solution by means of which the different deformations of the V belt in the various V-belt pulleys are equalised by finer matching of the profile of the V-belt pulley in order to avoid the disadvantages mentioned. This is achieved by the fact that, deviating from the respective width bo of the particular V belt 3 in the stretched condition, the respective width b of the V-shaped groove 1 of the V-belt pulley 2 is obtained as a function of the distance R of the neutral axis 4 from the axis 5 of the V-belt pulley 2 and of the respectively associated distance  DELTA r from the neutral axis 4 of the particular V belt 3 in accordance with the equation. <IMAGE>   <IMAGE>

Title: Fuel injection valve
Inventor: BURKEL RAINER DIPL ING
IPC: F02M51/08
Filed: 1985-01-16
Abstract: A fuel injection valve is proposed, which serves for the fuel supply of internal combustion engines. The fuel injection valve comprises a valve housing (1), a core (4), which projects into an inner chamber (6) of the valve housing (1) and is surrounded by a solenoid (7), and an armature (21) actuating a valve closing element (22). The valve closing element (22) interacts with a valve seat (19) and opens the fuel injection valve outwards. The armature (21) is designed as a permanent magnet and is moved by the force of the permanent magnet towards the core (4), so that the valve closing element (22) closes the valve seat (19). For opening the fuel injection valve, the solenoid (7) is supplied with current in such a way that an electromagnetic field acting in the opposite direction to the force of the permanent magnet field is built up, so that owing to the fuel pressure on the valve closing element (22), the valve closing element (22) is capable of moving in the opening direction of the fuel injection valve. <IMAGE>

Patent DE-3518750-A1 (DE)
Title: Spring-loaded safety valve
Inventor: COURA HERBERT
IPC: F16K31/122
Filed: 1985-05-24
Abstract: The invention relates to a spring-loaded safety valve, in particular for installations in the food-processing and drinks industry which can be cleaned automatically, with controlled additional loading by a drive cylinder which can be acted upon from a source of pressure medium in both the closing and opening direction of the safety valve and the piston of which acts on the valve stem carrying the valve-closing piece. The invention enables a spring-loaded safety valve with loading cylinder for the additional loading and for the pressure medium acting in the valve opening direction to be designed with only one piston in such a way that it still opens and closes in good time even if there is an interruption in the stroke and loading pressure medium. This is ensured inter alia by virtue of the fact that a floating piston arranged between two restoring springs is provided in the drive cylinder, which piston can be acted upon on both sides by pressure medium, that the valve stem ends in a freely movable manner inside the piston in an initial position of the piston, that the piston on the one hand acts on the valve stem in the closing direction of the safety valve under the action of the loading pressure medium, and that the piston on the other hand engages in a positive-locking manner on the valve stem in the opening direction of the safety valve under the action of the stroke pressure medium (Fig. 1). <IMAGE>

Title: Apparatus for reexciting flow in bulk material silos
Inventor: MOELLER HERMANN DR ING
IPC: B65D88/66
Filed: 1985-08-20
Abstract: The invention relates to an apparatus for reexciting an even flow in bulk material silos, having a run-off hopper (20a, 20b) which opens out into at least one run-off channel, having a perforated and preferably arched intermediate floor which is assigned to the run-off hopper and having a star-shaped two-dimensional grid arrangement which oscillates just above the intermediate floor, acts as a vibrator and is composed of individual two-dimensional grids (40) which are respectively assigned to the run-off channels and are independent of one another. The two-dimensional grids (40) are in each case driven by a vibrator (50) which is mounted outside the silo and insulated to ensure that no vibration is passed between the silo and the vibrator (50). A deaerating device (60) is arranged below the intermediate floor (30). Star-shaped or cross-shaped two-dimensional grids have an especially good loosening effect on certain bulk materials, as they let relatively large quantities of bulk material fall onto the intermediate floors. This can result in improved loosening of the bulk material and more rapid falling off into the run-off channels. <IMAGE>

Title: Process for installing imitation arches or other curved wall claddings into rooms
Inventor: VORINGER KONRAD
IPC: E04F13/00
Filed: 1985-09-07
Abstract: The invention proposes a process for installing imitation arches or other curved wall claddings into rooms delimited by walls of a different shape, in particular planar walls. In the said process, a frame-type, load-bearing substructure is fastened in the known manner on the wall parts to be clad. Said substructure forms spaced-apart, narrow, elongate bearing means which are in the shape of the cover layer of the arch or of the wall cladding and on which the cover layer is fitted in sections. In the known generic processes, the cover layer is formed from a plaster carrier of low inherent stability and of a plaster applied thereon and requires a complex substructure with small intervals between the bearing means, with the result that expenditure in terms of time and labour for installation is very large. In contrast, the curved sections of the cover layer are formed according to the invention from gypsum wall boards with fibrous filling materials, in particular of fibrous gypsum boards or gypsum plaster boards, such that the moisture content of the respective planar gypsum board is increased beyond the normal moisture range, thereafter the board is gradually pre-bent with permanent stressing and is then dried while maintaining the pre-bent state, and, from the dried and bent board, the individual curved cover-layer sections of matching curvature are subsequently cut to size. The cover-layer sections are thus very ... Original abstract incomplete. <IMAGE>

Patent DE-3600651-A1 (DE)
Title: Hook, in particular choker or cable-running hook
Inventor: SCHUETTE KARL-HEINZ
IPC: F16G11/14
Filed: 1986-01-11
Abstract: In the case of the hook, which serves, in particular, as a choker or cable-running hook, the insertion slot for the retaining or pulling member (60) is configured as a curved slot with the curvature sensor point in the direction of the slinging part (47). The hook has, moreover, in the region of the arched bearing surface for the retaining or pulling member (60), a greater width (B) than in the region (b) of the insertion slot. Instead of a conventional slinging fork, the hook (30A) may also exhibit, as slinging part, a shortening lug (47) having a keyhole-like through-opening (40) for a round steel chain serving as the slinging member (50A). In this way, it is ensured in a simple manner that the retaining or pulling member, once inserted into the hook opening, cannot slide out of the insertion slot again in the event of a slight tilting and oblique positioning of the hook, but also, in such a case, is deflected by the curved walls, located opposite one another, of the curved slot, and cannot slide through the insertion slot again when the retaining or pulling member is relieved of loading. The greater width of the hook in the region of the arched bearing surface for the retaining or pulling member prevents a tipping or tilting of the hook and consequently contributes decisively to the stabilisation thereof. Owing to the forged-on shortening lug, a considerable reduction in the weight of the slinging device is achieved. <IMAGE>
