Patent DE-3803320-A1 (DE)
Title: Internal combustion engine
Inventor: WIMMER MARTIN
IPC: F01N13/18
Filed: 1988-02-04
Abstract: Internal combustion engines, especially those working on the reciprocating piston principle, can be seen as resonance bodies. In this case the resonance volume comprises not only those hollow spaces situated above the piston, but also those below the piston, that is the combustion chamber and flow passage of the exhaust system and the exhaust system itself on the one hand, and the crankcase on the other. By adjusting the resonance volume as a function of the engine speed, the engine speed range in which the greatest torque or the highest power output of the engine is delivered can be varied. Whereas on the crankcase side only a speed-dependent control of the additional volume is necessary for this purpose, it must be ensured on the exhaust side that a secondary volume lying next to the flow passage of the exhaust system is not varied, but the resonance length and the resonance volume of the flow passage itself, in order to prevent unfavourable swirling and back pressure effects. This is achieved in that the length and hence the volume of the flow passage itself are adjusted. This is best achieved on the transition between engine exhaust and exhaust manifold, a sleeve belonging to the exhaust line, supported in this by means of a ball joint and arranged concentrically around the exhaust opening so that it fits tightly in a tubular extension of the exhaust passage in turn being displaceable, that is as a function of the engine speed.

Title: Dough press
Inventor: MAUZ MAX
IPC: A21C11/16
Filed: 1988-03-23
Abstract: In the case of dough presses, which are composed of a pot-like container (1) which has a floor which is provided with a pattern of perforations and of a piston which can be moved by means of a hand lever (7), it must be possible to separate the hand lever (7) together with the piston from the container (1), to enable the dough press to be accommodated in a dishwasher. The socket pins which have hitherto been used for this purpose are difficult to handle and, in particular, were easily lost. A dough press of this type is therefore to be provided with a releasable connection between the hand lever (7) and the container (1), which connection is to have no losable parts. According to the invention, the hinge bolt (13) is fixedly arranged at the end of the hand lever (7) and is provided with flattened sections (18), while the bearing bore (14), which is arranged in a shoulder (11) on the container (1), is provided with a slot (16) which extends up to the edge of the shoulder (11) and through which the bolt (13) together with its flattened sections (18) can be inserted. Giving the bearing bore (14) the shape of a slot with a centrally arranged slit (16) ensures that the hinge bolt (13) is accommodated especially securely. <IMAGE>

Filed: 1988-07-28
Abstract: A hydraulic arrangement for a vehicle comprises a hydrostatic transmission and an additional pump (7) for the power hydraulics of the consumers 15a, 15b, 16, 17 of a fork lift truck switch arrangement, using switching elements, facilitates the braking of the vehicle which includes the hydrostatic drive by additionally exploiting the drag effort available from the pump (7). For this purpose a delivered flow measuring valve (10) is incorporated in the feed pressure line (9) of the pump (7), which measuring valve (10) measures the speed of a drive engine (1) and above a specific speed connects the feed pressure line (9) to the load pressure line of a directional control valve block (11) of the power hydraulics. As a result the input pressure balance device (28) of a directional control valve unit (11) is brought into a blocked position and the delivered flow of the pump is obstructed, which leads to a braking effect. The valve (10) (Fig 2) may communicate with spring- loaded brakes for the shafts of the motors of the transmission. The valve (10) may communicate with an alternative control surface of the device (28) (Fig. 3). <IMAGE>

Title: Process for producing light-weight aggregates having a low density
Inventor: ACKERMANN MANFRED
IPC: C04B18/06
Filed: 1988-10-12
Abstract: To produce a light-weight aggregate having a low density and to use fine-grained to fine pulverulent combustion residues formed in fluidised-bed furnaces, a process is employed according to which light cores such as, for example, granulated Styropor (rigid polystyrene foam) or spheres of foam material whose water absorption is very low and whose wetting with water is difficult under water-containing suspensions are made wettable by appropriate treatment processes using foam material formers. After wetting, the predominantly fine pulverulent mixtures of inorganic binders and thermally treated mineral materials are then applied in the form of a shell to these cores. The selection of the core-forming grain size is matched to the desired grain size of the aggregate. The shell thickness is determined by the duration of the application process as a function of the desired grain strength. Depending on the starting material or the field of application, binder in the form of cement or of lime is added or utilised. The grain formed in this way is cured or subjected to thermal curing by the lime-sand brick process.

Patent DE-3900286-A1 (DE)
Title: Transformer
Inventor: MATSUMURA TOMOYA
IPC: H01F19/04
Filed: 1989-01-07
Abstract: A transformer for a switched-mode operating-voltage source of the flyback converter type has a ferrite core (10, 11) with two lateral limbs (10a, 11a) and a middle limb (10b, 11b) which is shorter than the lateral limbs, so that an air gap (G) is formed in the part of the magnetic circuit which runs through the middle limb. In order to prevent the leakage flux occurring in the air gap from being coupled to windings (17, 18) on a winding body (15) which surrounds the middle limb of the ferrite core, the air gap (G) is arranged on the end section of the middle limb in the vicinity of the end of the winding body, with a dielectric band (16b) surrounding the winding body (15), so that the air gap is not surrounded by a winding. In this way, eddy-current losses in the windings and partial temperature increase in the windings are avoided. <IMAGE>

Title: Glass-fibre-reinforced, resin-bedded roof bolt
Inventor: GERDES KNUD DR
IPC: E21D20/02
Filed: 1989-01-31
Abstract: A resin-bedded bolt consisting on the whole of a glass-fibre-reinforced tube can be effectively used as a tension element by the tube being slit crosswise at both ends and by a tapered expanding mandrel with concentric inner bore being inserted into these slots. This expanding mandrel and the glass-fibre-reinforced tube are surrounded by a taper sleeve which has an inner wall conforming to the outer wall of the expanding mandrel, in which arrangement they run parallel to one another in a transition area so that a considerable amount of force can be applied. At the free end, the taper sleeve has a blind hole with a metric internal thread so that a plug-type connection with integrated non-return valve can be inserted and secured, so that adhesive material, i.e. resin, can be injected without great effort. The resin-bedded bolt can be prepared as a unit at the place of use and can then be placed, in which case it can be assembled from few parts and then effectively secured and restrained in the borehole. <IMAGE>

Title: DNA vector including multiple cloning site - for cloning, specific mutagenesis, sequencing and optimised expression of inserted genes, and construction of gene banks
Inventor: BUETTCHER VOLKER
IPC: C12N15/70
Filed: 1989-09-07
Abstract: New vector is a circular, double-stranded DNA molecule contg. at least the elements, (1) origin of replication (ori1); (2) promoter; (3) ribosome binding site (RBS); (4) multiple cloning site (MCS) and (5) origin of replication (ori2) of a single-stranded DNA phage. The elements 2, 3 and 4 exist, in the order quoted, in the transcription direction. Also new are kits contg. this vector. The promoter is pref. strong and esp. inducible; specifically the lambda-PL, tac or rac promoters. the MCS has, at its 3'-end, a stop codon for all 3 reading frames and also a start codon at the 5'-end. It restriction sites which allows cloning in all 3 frames. Ori2 is derived from the phages fl, M13 or SP6, and the vector may include a termination sequence, esp. the T1 and T2 sequences of the rrnB protein. USE/ADVANTAGE - The vectors are useful for cloning, targeted alteration, sequencing and/or expression of genes inserted into MCS, and for construction of (partial) gene banks. It combines the properties of a strong expression vector with the advantages of a single-stranded DNA phage, i.e. it is simple to use for site-directed mutagenesis; allows the RBS/start codon to be optimised, and almost all genetic engineering operations can be carried out in the same vector without recloning.
