Patent DE-3734413-A1 (DE)
Title: Clamping system and clamping-set systems
Inventor: RUEHLEMANN JOACHIM
IPC: F16D1/08
Filed: 1987-10-12
Abstract: The invention proposes a new clamping system in which the prior art and experience with the production of cylindrical bodies of complicated cross-section without metal removal are the prerequisite for a principle of action according to which radial forces for the build-up of a loadable surface pressure in the joints between the shaft, the hub and the clamping set are produced directly. In addition to practical advantages, for example rapid assembly without an assembly spanner, and functional advantages, such as the use of this system for the construction of clamping elements, switchable free wheels and removable securing elements for shafts and bores, this principle of operation offers particular cost advantages over known clamping set embodiments.

Title: Device for applying force, in particular an assembly device for a pipe-joint coupling on a pressure basis
Inventor: KNIPPING DANIEL
IPC: B26D5/12
Filed: 1988-10-08
Abstract: A description is given of a device for applying force, in particular an assembly device for a pipe-coupling on a pressure basis. In order to also be able to apply larger forces without problem, in particular to make pipe-joint couplings on a pressure basis for pipes of larger diameter (e.g. up to half a metre and more), provision is made for a tension and compression device to be designed as a tension and compression tie, roughly U-shaped in plan view, with retaining webs surrounding the lever arms on both sides. At least one lever arm is connected to a force-application means in an articulated manner, and the other lever arm is either linked to the retaining webs or is connected to a further force-application means in an articulated manner. It is especially advantageous here that the force-application means can preferably be designed so as to work compressively, since this allows the dimensions to be kept small.
Patent DE-3838159-A1 (DE)
Title: Spotlight (searchlight)
Inventor: MANUNTA GIORGIO
IPC: B60Q1/064
Filed: 1988-11-10
Abstract: A spotlight in which a cup-shaped reflector is accommodated inside a housing and connected to a rear pot-shaped body of the latter on the one hand via coupling parts which define a hinge having an essentially horizontal axis, on the other hand via an attachment device which is coupled in a manner so that it can be dismantled, to a motorised adjusting arrangement for the position of the reflector with respect to the hinge. The attachment device provides the use of a deformable coupling piece which can be displaced relative to the rear body between a quiescent position in which it bears on the rear body and a working position in which it is coupled to an output element (initial element) of the adjusting arrangement as a result of an axial displacement which is exercised on the adjusting arrangement when coupling/decoupling the output element to/from the deformable coupling piece.

Title: Method and device for detecting a repeat start and corresponding reduction in the supply of fuel in an internal combustion engine
Inventor: ZECHNALL MARTIN DIPL ING DR
IPC: F02D41/06
Filed: 1988-12-09
Abstract: In a method and a device for detecting a repeat start and corresponding reduction in the supply of fuel, in particular fuel injection, in an internal combustion engine, it is proposed, when starting occurs, to store a special repeat start flag in an (external) non-erasable memory. The non-erasable memory, e.g. external RAM, does not lose its contents even when the ignition is switched off. In this process, the duration of uninterrupted operation of the engine occurring after starting is measured and below a minimum operating period a first item of information is stored in a non-erasable memory, which item of information is read out during a subsequent starting process and characterises the latter as repeat start whilst above a predetermined minimum operating period the item of information which is stored in the non-erasable memory characterises that the subsequent start is not a repeat start. <IMAGE>

Title: Device for clamping a linearly displaceable subassembly in a guiding subassembly
Inventor: DRASSDO BERNHARD DR ING
IPC: F16C29/00
Filed: 1989-03-16
Abstract: The invention relates to a device for clamping a linearly displaceable subassembly in a guiding subassembly, usable in machine tools for stopping non-moving shafts during the working process. It is the aim of the invention to obtain high clamping forces and great transmission rigidities at the clamping point with a small source of force and without transmission members, and also to compensate for assembly and guiding errors. The clamping jaws 18, which move in opposite directions on a clamping spindle, for bilateral clamping are centrally received with play, guided loosely between stops 14, 15, 16, 17 and have three clamping wedges 20, 21. The wedge surfaces of two clamping wedges 20 run along the guiding direction and correspond with a wedge-shaped clamping groove 8 in the linearly displaceable subassembly 6. The third clamping wedge 21, centrally offset on the opposite side, has wedge surfaces transversely with respect to the guiding direction and is coarsely fixed in prismatic grooves 9, running at right angles to the clamping grooves 8, in the guiding subassembly 1. During the clamping process, firstly the clamping wedges 20, 21 centre themselves positively in the clamping and prismatic grooves 8, 9. Subsequently, their wedge action leads to a non-positive clamping. <IMAGE>

Title: Hammer with air spring percussion mechanism
Inventor: WANNER KARL DR ING
IPC: B25D11/12
Filed: 1989-04-01
Abstract: In the case of a motor-driven hammer with air spring percussion mechanism, the performance, especially when working soft materials, is to be improved. In this case, an excessively weak recoil of the percussion member led to undesired ventilation processes through the air equalisation hole and thus to a reduction in efficiency. According to the invention, the air equalisation control is effected solely by the drive piston 11, whose seal 14 coincides with an annular groove 15 when at the dead centre close to the tool. Through the annular groove 15 and the longitudinal grooves 17, a defined equalisation of the air-cushion space 18 with the environment takes place exclusively at this point in time. The percussion member 4 is not involved in the control. <IMAGE>

Title: Electric motor with reduced vibration for acoustically sensitive area - has asymmetric air gap for generating magnetic side thrust on output shaft to minimise effect of pulsed torque variation
Inventor: HEYDT THOMAS VON DER
IPC: H02K29/12
Filed: 1989-05-11
Abstract: The electric motor comprises a brushless dc drive with permanent magnet rotor (1) and pulsed stator winding (12) for generating a rotating magnetic field in stator (7). Troublesome rotor oscillations giving rise to noise are reduced by promoting a magnetic thrust at right angles to the rotor axis. The thrust holds the drive shaft (6) firmly but flexibly against the bearing areas of housing (8). The required side-thrust is produced by an asymmetric airgap and several methods of achieving this are described. USE/ADVANTAGE - In applications where quiet running is important.  Is particularly effective where drive shaft is vertically mounted.
