IPC: F02M59/10
Filed: 1988-06-27
Abstract: In addition to roller bearings (6) with cylindrical rolling elements (7) merely absorbing radial forces at one point of the camshaft (1), a bearing for the camshaft (1) of a fuel injection pump for internal combustion engines comprises a plain thrust bearing (9) for the camshaft (1) between two adjacent cams (2), preferably approximately central in the housing (3), thereby defining the axial alignment of the camshaft (1) in the housing (3).

Patent DE-3831655-A1 (DE)
Inventor: WRIEDT KARL-HEINZ
IPC: A45C5/02
Filed: 1988-09-17
Abstract: Aluminium suitcases or similar suitcases, which consist of several panels and a frame composed of profile elements, serve in many cases for transporting and for storing expensive equipment. In this case, the profile elements of the frame form two outer profiles and two central profiles. The outer profiles and central profiles are connected to each other by perpendicular profile strips. The intention of the invention is to improve the stability of a suitcase of this type. The invention proposes to manufacture the central profiles of uninterrupted and continuous profile strips, these central profiles having a rounded contour in the region of the suitcase edges, inserts being able to avoid weakening of the central profiles in the region of the suitcase edges. Furthermore, the stability can be increased by the fact that the individual profile elements are linked by means of pin connections to connection elements which connect the individual profile elements to one another. Finally, the outer profiles can advantageously be formed from angular profile strips, and the individual elements of the suitcase can be bonded together so that an extremely stable structure is achieved by this means too.
Patent DE-3835504-A1 (DE)
Title: Mining truck for suspended monorails
Inventor: SCHIMMEL WERNER DIPL ING
IPC: B61B13/04
Filed: 1988-10-19
Abstract: The known suspended monorails have the disadvantage that they cannot be adapted to the requirements which frequently change during normal operating cycles and in particular the mining trucks cannot be individually influenced in terms of their travel behaviour. The mining truck, according to the invention, for suspended monorails is intended, in contrast, to permit the possibility of individually influencing its travel behaviour and in particular its speed. For this purpose, control elements are provided on the mining truck itself and/or along the railway, which control elements act on a control circuit which is integrated into the mining truck and itself controls a frequency converter, in such a way that the rpm of the motor and thus the speed of the mining truck can be adapted to prescribed states. By means of the corresponding selection of the control elements, for example as control elements which act in a weight-dependent and/or weight and acceleration-dependent fashion or else as control elements which act on the control circuit in the motor drive so as to decelerate, or completely bring to a stop, the mining truck when it approaches mining trucks travelling ahead or/and obstacles coming up in the travel path.
Patent DE-3837726-A1 (DE)
Title: Process for the loading of heavy cargo by means of a heavy-cargo loading bridge having more than one raising and lowering device
IPC: B66C19/00
Filed: 1988-11-07
Abstract: The process, for which a patent is applied, for the loading of heavy cargo by means of a heavy-cargo loading bridge is characterised in that, in a loading bridge, by means of two or more raising devices working independently of one another, the raising and lowering cycles during the transfer of cargo to be raised, especially of containers during loading and unloading, can be shortened and the horizontal transport of the load can be carried out separately from the raising and lowering operations. The apparatus for carrying out the process allows a further shortening of the work cycles during the loading and unloading of heavy loads, in that one or more transport vehicles for the horizontal load movement can convey the heavy load independently of the raising and lowering devices. A further shortening of the work cycles becomes possible in that the further raising devices or transport vehicles, impeding the travel route of a raising device or of a transport vehicle, can be moved away and, after the vehicle having priority has passed, can be returned to the travel route.
Patent DE-3839196-A1 (DE)
Title: Device for determining thermal neutron flux multiplicitation and neutron emission
Inventor: EYRICH WERNER DR
IPC: G21C17/06
Filed: 1988-11-19
Abstract: The invention relates to a device for determining thermal neutron multiplication and neutron emission in systems containing fissionable material by means of detection both of spontaneously emitted neutrons and of neutrons induced by at least one point neutron source. The device according to the invention is intended to be largely insensitive to fluctuations in the positioning of the system containing fissionable material between source and detector. Detector and source are intended to have a separation which allows systems containing fissionable materials, and which have no smooth surface, such as for example a fuel element, also to be moved relative to detector and source without contact, without leaving the measuring position. The object is achieved according to the invention in that, for detection of the induced neutrons, the separation of neutron source and neutron detector, reduced by the dimension of the system containing fissionable material in the line connecting them, amounts to at least 3 cm, in that, in the measurement of thermal neutrons, the system containing fissionable material is approximately in the middle between neutron source and detector, and in that, in the measurement of epithermal neutrons, the system containing fissionable material is in the vicinity of the detector.

Title: Process for regeneration and increasing the activity of activated cokes of dry flue gas desulphurisation
Inventor: KINDER REINER DR RER NAT
IPC: B01D53/50
Filed: 1989-01-20
Abstract: The invention relates to a process for regeneration with simultaneous increase in activity of activated cokes which are used in the adsorptive flue gas desulphurisation. Use of the process has the effect that the carbon losses necessarily occurring in the regeneration are reduced, the regeneration rate is improved and the activity is retained and even increased. According to the invention the regeneration is carried out with addition of an external carbon under reaction conditions known per se, as a result of the grain size, source and moisture content of the added carbon, the added carbon forming the reducing agent for the conversion of SO3 to SO2.
Patent DE-3909184-A1 (DE)
Title: Ball-game racket with variable centre of gravity
Inventor: SATTELMEYER RICHARD DR
IPC: A63B60/04
Filed: 1989-03-21
Abstract: In all ball-game rackets currently in use, the distribution of weight between the striking surface and the handle, with its grip, cannot be varied so that the centre of gravity retains its position. The object of this invention is to develop a racket which, during the striking movement, permits a displacement of the centre of gravity towards the ball striking surface and thus causes the transmission of a higher impact energy from the racket to the ball. To this end, a cavity is made in the racket handle, in the region of the grip surface, in which cavity a weight 1 is movably contained. In the position of rest, 1 is retained at the end opposite to the ball impact surface, and in the striking movement 1 is moved towards the racket head by the force of acceleration, being braked at the end of the cavity. <IMAGE>

IPC: H02J7/14
Filed: 1989-10-07
Abstract: The proposal is for a device for making the charging voltage of a vehicle power supply system symmetrical in which two batteries providing said power supply are charged in such a way that the one in a lower state of charge is given priority during charging. Here, the voltage is regulated in the prior art manner by switching the generator exciting current on and off.
