Patent DE-3103107-A1 (DE)
Title: Flexible shaft coupling
Inventor: WALTER JUERGEN ING GRAD
IPC: F16D3/80
Filed: 1981-01-30
Abstract: In a shaft coupling with fluid displacement damping, in which a fluid is passed out of a chamber (18) in which pressure is building up into a chamber (19) at lower pressure, it is not sufficient to prevent pressure losses by seals (31, 32) only to the outside but it is also necessary to ensure that no leakage openings arise between adjacent chambers (18, 19). The differential pressure required for damping may be to a large extent cancelled out by unwanted leakage openings between adjacent chambers (18, 19). The fluid is forced out of chamber (18) into chamber (19) via restriction openings (33, 34) formed by the ends (21, 22) of the pressure chambers and the end faces (23, 24) of the spring elements (15). In order to permit a larger radial displacement of the hub part (10), it would be necessary to leave a free space, corresponding to the desired radial play, between the ends (21, 22) of the pressure chambers and the hub part (10). However, this free space gives rise to the unwanted leakage openings at the points under the highest pressure. In order to prevent this, the ends (21, 22) of the pressure chambers must be made locally flexible, while the total restriction openings (33, 34) should be kept the same size. For this reason, the ends (21, 22) of the pressure chambers should be formed right through to the hub part (10) by the housing (12), the connecting flange (11), the flexible ring elements (25, 26) and the receiving grooves (29, 30). <IMAGE>
Patent DE-3108277-A1 (DE)
Title: Heading machine with activated shearing head
Inventor: JANSSEN WERNER
IPC: E21D9/10
Filed: 1981-03-05
Abstract: Roadways in underground mining and in tunnelling are increasingly being driven by heading machines which have a shearing head which is fitted with picks and is in turn arranged on a pivotably mounted cutting arm. The shearing work is facilitated and improved by the surface pressure at the points of the picks being briefly increased owing to the fact that the hydraulic motor driving the shearing head can be driven via a pulsating oil flow. In the process, the pulsating oil flow is divided or chopped into several oil flows via a hydraulic control device also designated as pulse generator and having a rotary slide valve. The vibrations occurring as a result substantially facilitate the freeing work.
Patent DE-3109361-A1 (DE)
Title: Motor-operatable portable plane
Inventor: SPRINGE HORST AUF DER
IPC: B27C1/10
Filed: 1981-03-12
Abstract: The invention relates to a motor-operatable portable plane, the housing of which has at the bottom two sliding surfaces which form a sole of the plane and between which a cutter block fitted with planing blades projects. The sliding surface lying in front of the cutter block in the planing direction has a surface section which lies sunk over part of the width of the sliding surface in the planing direction. It is thereby possible to place the portable plane against a surface in such a way that a veneer-type edge projecting above a panel surface can reach behind the sliding surface resting on the panel and can be planed off by the cutter block.

Patent DE-3114760-A1 (DE)
Title: Pendulum quadrant slope profile meter
Inventor: AHNERT FRANK PROF DR
IPC: G01C9/12
Filed: 1981-04-11
Abstract: The device is used for rapid and yet accurate surveying of slope inclinations (angles of slope) and slope profiles (profiles of slope) of up to 45 DEG . It consists of two equally long limbs, which are firmly joined to one another at a right angle and are used to measure profile length by picking off the profile distance with a constant step length in the manner of dividers. The measuring scale for determining the slope inclination is mounted in such a way that it forms the hypotenuse of a right-angled isosceles triangle whose perpendicular sides are the limb segments located over the fastening points of the measurement scale (cf. Fig. 1). The pendulum, which is suspended at the apex of the right angle, directly indicates the associated slope inclination on the measuring scale in the case of each length measurement step. For a step length of 2 m and a measuring scale length of 1 m, the device determines the slope inclination to an accuracy of approximately 0.1%, i.e. to approximately two to three minutes of arc in angular measure. Fields of application: any investigation and work which includes recording of the inclination angle of surfaces, or the recording of slope profiles (profiles of slope) - eg. in roadbuilding, in geology, geomorphology, soil science, geoecology, agricultural science and landscape gardening. The device is also suitable in many cases instead of a water level. <IMAGE>

Patent DE-3221444-A1 (DE)
Title: Slide projector
IPC: G03B23/04
Filed: 1982-06-07
Abstract: The invention relates to a slide projector having a magazine for accommodating the slides and having a drive arm which is mounted on a shaft and can be driven by a motor and engages on a displaceable frame and during a rotation of 360 DEG  transports a slide held in the frame from the beam path into the magazine and transports the next slide from the magazine into the beam path. In order to ensure reliable and immediate interruption of this transport movement in each case after termination of a rotation of 360 DEG  by the drive arm, it has previously been necessary to use a relatively strong spring. The latter was tensioned by an actuator effecting the coupling in, with the result that it was necessary for said actuator to have a correspondingly large power rating. By contrast, in accordance with the invention this actuator can be designed for a lower power if the spring can be separated by the rotary movement of the drive arm or of a part rotating therewith. This purpose can be served, for example, by a leaf spring which is mounted on the drive arm, and does not need to be tensioned until towards the end of the rotation of 360 DEG .
