Patent DE-3633192-A1 (DE)
Title: Air rate meter according to the vortex velocity principle
Inventor: ELLMANN SIEGFRIED DIPL ING
IPC: G01F1/32
Filed: 1986-09-30
Abstract: An air rate meter according to the vortex velocity principle has a measuring tube, in which at least one disturbance member is located for the purpose of vortex formation and in which at least one pressure transducer for generating vortex pulses is provided; the pressure transducer is followed by an evaluation device with a digital counting circuit (5), the count of the digital counting circuit (5) being converted into an analogue value which represents a control variable for a downstream control instrument. An alternating voltage proportional to the frequency of the vortex pulses is rectified by means of a rectifier (1), so that a measured value is already available after half a period duration and the measurement rate is thus increased to two measurements per period duration. At each zero crossing of the alternating voltage phase, a zero crossing detector (2) generates a needle pulse which resets the counting circuit (5). Until the next zero crossing appears, the pulses of a square-wave pulse generator (4) are counted and stored. The counting process starts anew with the subsequent resetting of the counter circuit (5). <IMAGE>

Patent DE-3723665-A1 (DE)
Title: Hybrid engine (motor) having a performance-increasing arrangement of the oxidiser tank and fuel block
IPC: F02K9/72
Filed: 1987-07-17
Abstract: In the case of hybrid engines according to the prior art, the oxidiser flows through a solid fuel block. In this case, the geometry of the fuel block changes while it burns away, which has a disadvantageous effect on the fuel/oxidiser mixture ratio. The novel arrangement of the main components overcomes these disadvantages. The fuel block (5) is followed up by the amount by which it is burnt away by means of the drive unit (A), via a threaded nut (3) and threaded spindle (4). The insulating cylinder (6) and insulating flange (7) protect the threaded spindle and the tank respectively against being thermally stressed. In addition, the insulating flange prevents the fuel block twisting, by means of the sliding blocks which are introduced. The advantages which are achieved with this arrangement are constant flow conditions while the solid fuel is burning away in the combustion chamber, even in the case of thrust throttling. <IMAGE>

Patent DE-3728687-A1 (DE)
Inventor: FUENFHAUSEN DIETER
IPC: B22D29/00
Filed: 1987-08-27
Abstract: The invention relates to a method for removing internal cores from castings after the solidification of the cast metal, the casting being placed on a rapping table and held there. A ram of an air hammer is then used to rap on a part of the wall of the casting with a predetermined striking or rapping energy until cracks form in the core and the core has broken into several parts. After rapping, the casting is conveyed to a vibrating table and there firmly clamped. On the vibrating table, the casting is subjected to vibration energy, with the result that abraded foundry sand trickles out of openings in the casting or fragments of foundry sand are broken down further by the vibration energy. After the casting has been emptied, it is carried away. A device for carrying out the method is characterised by a rapping table, above which an air hammer with a ram is arranged, and by a vibrating table with means for generating vibration energy and means for transmitting the vibration energy to a casting. <IMAGE>

Patent DE-3740911-A1 (DE)
Title: Filter device for cleaning polymer melts
IPC: B29C48/693
Filed: 1987-12-03
Abstract: The filter device has in a housing a passage bore, which forms the flow channel, is enlarged by two chambers and has intermittently driven rolls with axes arranged transversely with respect to the flow channel. In the operating state, the throughflow bores located in the rolls are in alignment with the passage bores of the housing and thus form the flow channel, which is not deflected. In the throughflow bore of the first roll there is a shoulder, against which the filter insert, which is arrested by a spacer sleeve, comes to bear. When the first roller is swivelled through 180@, the filter insert is reversed and flushed from the rear side, by the melt continuing to flow in the flow channel. The second roll, swivelled simultaneously with the first roll through 90@, forms a melt outflow channel together with the outflow bore located at the bottom of the housing, the recess located on the roll circumference and the passage bore. In every filter position, the flow channel does not have any contact with the atmosphere, so that no bubbles can form in the melt.

Patent DE-3800333-A1 (DE)
Title: Screw-connection for precast concrete compound units
Inventor: KLASEN ANTON
IPC: E04B1/21
Filed: 1988-01-08
Abstract: The present invention relates to screwing precast concrete compound units on one another. Up until now, concrete parts have had to be connected by casting or adhesively bonding them, by plugging them together or by provisionally connecting them in some other manner. This not only resulted in unsatisfactory results in terms of stability, but was also frequently dangerous. Just think of the large number of accidents in conjunction with silo construction in agriculture. The novel connection makes it possible not only to produce strong, but flexible connections, but at the same time also to minimise the safety risk. The connection is arranged at a 45-degree angle with respect to the concrete part. It comprises a screw which is mounted on either side of a hemispherical joint. An endless seal is located between the two structural parts. The flexibility of the entire "structure" can be influenced by the thickness of this seal. The hemispherical mounting achieves the effect that, even in the event of relatively large expansions, the connection holds satisfactorily and also remains sealed. The two ends are arranged within the structural part, with the result that, upon filling in the screwed openings, a planar surface remains.
Patent DE-3800606-A1 (DE)
Title: Two-stroke internal combustion engine with an oscillating piston divided cylinder arrangement serving for the delivery of fresh gas or for secondary expansion of the combustion gases
Inventor: KLAUE HERMANN DR ING
IPC: F01L7/12
Filed: 1988-01-12
Abstract: The invention relates to a two-stroke internal combustion engine with divided cylinders fitted at the side of the working cylinder and serving for the delivery of fresh gas or for secondary expansion of the combustion gases, which cylinders have oscillating pistons, the axes of which run parallel to the crankshaft centre axis and about which the pistons are made to oscillate, driven by the crankshaft. The oscillating pistons have cylindrical enlargements which are supported in bores of cylinders cast together with the working cylinder. The divided cylinder running surfaces of the oscillating pistons, on the other hand, are arranged in a single or multipart housing enclosing the working cylinder or cylinders. This measure simplifies the two-stroke internal combustion engine of the type with divided cylinders arranged at the side of the working cylinders. This makes manufacturing easier. For example, the housing having the running surfaces for the oscillating pistons and simultaneously designed as crank case can be manufactured from die-cast lightweight alloy, in which the running surfaces for the oscillating pistons are produced at the same time in the casting process without finish machining.
