Title: Hammer drill
Inventor: GRIESE MANFRED DIPL ING
IPC: B25D16/00
Filed: 1983-08-11
Abstract: An electrically operated hammer drill is proposed in which a tool head is acted upon by a percussion mechanism, in particular an air-cushion percussion mechanism, and is driven in a rotary manner via a gearing, it being possible to reverse the direction of rotation at least briefly. Arranged in the gearing for the rotary drive is an engageable and disengageable driving clutch (19, 20) which is under the effect of control members (23, 24, 25) dependent on the direction of rotation. These control members (23, 24, 25) are designed in such a way that the driving clutch (19, 20) is constantly engaged in one direction of rotation of the driving gear train and is engaged and disengaged intermittently in the other direction of rotation. This enables a series of brief rotary blows to be imparted to a drill bit jammed in the rock and in this way enables it to be freed again. <IMAGE>

Title: Hydraulic control system for a control cylinder and use of the same
Inventor: HAMPEJS KAREL
IPC: F15B9/09
Filed: 1983-10-28
Abstract: The adjusting information is carried in a control circuit to two drive motors (10, 20), the drive shafts (11, 21) of which are coupled to one another via a differential screw mechanism (30). While the nut part (33) of this mechanism is rotatably mounted in a fixed position on the housing, the screw part (32) can be displaced axially. The valve piston (51) is displaced in a directional control valve (50) present between this mechanism (30) and one drive motor (10), and thus a pressure fluid can flow towards and away from an actuating member. Furthermore, a control circuit with considerable dynamics can thus be provided with short response time and high precision. <IMAGE>

Patent DE-3411820-A1 (DE)
Title: Shelf cabinet
Inventor: FUELPEN HEINRICH VAN
IPC: A47B53/02
Filed: 1984-03-30
Abstract: The invention relates to a shelf cabinet, having side walls and having shelf elements which are arranged inside the cabinet space and are displaceable in a direction extending from one side wall to the other. It is very complicated and also very time-consuming to design the individual shelf elements to be closable and to close and open them regularly for use. These disadvantages are eliminated according to the invention in a shelf cabinet which is characterised in that the shelf elements are accessible only at their sides parallel to the side walls, in that a door adjoins one of the side walls, the width of which door corresponds to the size of the free space serving for displacing the shelf elements, and in that the displacement of the shelf elements pushed up to the other side wall can be blocked by the door. Since the shelf elements are thus accessible only from the cabinet space and the cabinet space can be locked solely by the door which also blocks the displaceability of the shelf elements, rapid closing and opening of the shelf cabinet is possible in a simple construction.

Patent DE-3418737-A1 (DE)
Title: Guide star for rotating treatment machines
Inventor: MELLES RAINER DIPL ING
IPC: B67C7/00
Filed: 1984-05-19
Abstract: In machines of this type, guide stars are provided which must be provided with receptacles of different sizes according to the type of containers used, such as bottles, cans and the like, and the level of engagement or support of the said receptacles itself likewise may be different. It is therefore necessary to exchange the stars or star-like rings. To reduce the outlay on disassembly and reassembly incurred in this way, the invention provides for the guide star to be resiliently pressable, using a clamping device which is movable resiliently in an axial direction towards the guide star, in the clamping direction of the clamping device within a specific axial path against the centring surfaces of the guide star. When bodies of revolution which are mounted in a vertically movable manner on a central column are used, the invention provides for the guide star to be held using a clamping device which is arranged on the body of revolution and acts in an axial and/or radial direction, the star and/or parts thereof being released and/or clamped by preferably axial movement of the body of revolution. This version permits the universal application of the said clamping device, regardless of the respective heights of the guide stars to be used.

Title: Electric motor
Inventor: KRESS WILLY
IPC: H02K11/026
Filed: 1985-01-25
Abstract: An electric motor, especially for electric hand tools such as drilling machines, angle grinders and the like. Arranged at one end of the stator is a motor bridge which comprises at least one printed-circuit board region, is preferably a printed-circuit board on which electric sub-components are mounted, in an electrically connected manner by means of suitable conductor tracks, mainly for suppression, as well as the brush guides. The printed-circuit board is connected to the stator (10) by means of fixing pins and, in consequence, at the same time produces the electrical contact with the stator winding ends, via contact tongues which originate from it. Further contact tongues on the printed-circuit board result in both a mechanical and an electrical connection to the housing for the control electronics. The printed-circuit board itself either forms a complete ring for the retaining opening of the associated armature-shaft roller bearing, or this is formed by at least one laterally attached bearing half-plate, which is latched to the printed-circuit board. The bearing half-plate can also itself carry the fixing pins for mounting on the stator (10), integrally. <IMAGE>
Patent DE-3503741-A1 (DE)
Title: Method for the effective output regulation of pumps in the case of variable volume flows in heating systems or for other systems comprising other media
Inventor: SCHILLING HEINZ
IPC: F04D15/00
Filed: 1985-02-05
Abstract: If drive power is to be saved by matching, for heating systems with variable volume flows or for other systems comprising other media, the output power of the pumps to the required volume flow of the installation, this requires a suitable controlled variable. The controlled variable used hitherto, system differential pressure equals pump differential pressure, does not permit effective power output regulation in this case, since this controlled variable picks up as a deviation only the increasing differential pressure in accordance with the pump curve. The controlled variable used according to the invention is therefore a consumption-side pipe subsystem resistance. The novel controlled variable thus takes into account, at the same time, the pipe system resistance of the plant which decreases with the square of the reduced volume flow, so that the pump output power can largely be matched to the actual requirement. Via a speed control of the pump drive it is thus possible to achieve a maximum saving in pumping energy.
