Title: Method of machining workpieces
Inventor: MUELLER ALFRED DR
IPC: B25J13/08
Filed: 1984-11-28
Abstract: In order to increase the accuracy of the direct programming by the programming procedure "Following and Storing" to establish the tool normal to the workpiece surface and to reduce the force-depriving movement of large masses, a sensor known per se is used to scan a marking arranged on the workpiece, which sensor regulates the axes of the robot in such a way that these axes always follow the marking, and at predetermined points the coordinates of the axes are input as program points into the NC-system.

Title: Hammer drill
Inventor: BRIX PETER
IPC: B25D16/00
Filed: 1985-02-18
Abstract: The hammer drill (1) has a striking element (11) which is set in reciprocating movement by a piston (13) via an air cushion or a spring element. To perform a stroke movement, the piston (13) is connected to a connecting rod (14) which is driven by the crank (16). The crank (16) has a crankpin (17) inclined at an acute angle to its axis of rotation. To change the piston stroke, the crank (16) is displaced along the axis of rotation, as a result of which the effective crank radius of the crankpin (17) is adjusted. <IMAGE>

Patent DE-3522760-A1 (DE)
Title: Impact bell for driving boundary markers into the ground
IPC: G01C15/04
Filed: 1985-06-26
Abstract: Impact bells serve to drive boundary markers into the ground, since the boundary markers are sensitive to direct impact, for example with a hammer, and can be damaged. Impact bells essentially consist of a head part and side walls which run perpendicularly to the head part and reach over the head of the boundary marker. To prevent the impact bell from adhering firmly to the head of the boundary marker and to facilitate the release and bring about better centring of the impact action, it is proposed to design the side walls to be conically tapered and to arch the inner surface of the head part to the inside and furthermore, in order to increase the safety, to produce the impact bell from a polyurethane elastomer. <IMAGE>

Patent DE-3533061-A1 (DE)
Title: Hydraulically operated press
IPC: B30B15/04
Filed: 1985-09-17
Abstract: A hydraulically operated press has a T-shaped upright which has a rearward supporting column with a forward-projecting and horizontally extending bottom piece and top piece. Together with the supporting column, these delimit an upright aperture into which there emerges a tool path of a through aperture of the supporting column. Via the through aperture, the tools can be transported on the shortest path from a rack set up behind the press into the upright aperture, without the risk that the tools will be damaged by collision. The supporting column furthermore accommodates a reservoir for pressure medium. The press furthermore has a piston-cylinder arrangement and a ram, which are situated in the top piece, of which the ram is guided vertically by way of at least two guides. The pressure-medium reservoir and the guides lie in the area outside the through aperture, allowing the tools to be transported unhindered into the upright aperture.

Title: Binaural hearing aid for instructing the hard of hearing, educating and training in hearing
Inventor: WAGNER HERMANN DR ING
IPC: H04R25/00
Filed: 1986-03-01
Abstract: The aim of the invention is the extensive utilisation of the capabilities for acoustic signal processing and perception of the direction of sound, including the reaction of turning towards the sound, which remain in the hard of hearing. The invention achieves the object of combining in one hearing aid the required features to be found in each case individually by themselves in numerous known devices. The essence of the invention lies in the fact that two wideband microphones are fastened close to the ear and at least with the spacing of the ears on two preferably half-open dynamic earphones, or on a holder, in such a manner that they can be turned towards the sound source with the correct sides by moving the head, that in spite of using only two preset high-pass filters, the asymmetric binaural transmission principle can be implemented without crossing channels which interferes with directional hearing, that the maximum-level control loops inserted into the two signal paths contain full-wave rectifiers shortening the correction time, and that, in a special embodiment, the two electronic amplifiers form one constructional unit similar to a headphones system with the phones and the microphones.

Patent DE-3626757-A1 (DE)
Inventor: AUGUST PAUL DR
IPC: F02B23/08
Filed: 1986-08-07
Abstract: The internal combustion engine forms squeeze gaps (25) between the pistons (2) and the cylinder head (5) and is provided in addition with deflection means (4, 20) in the combustion chamber (8) which produce a rotary flow in the combustion chamber. The floor of the combustion chamber is formed by a trough-shaped cavity (22) in the floor of the piston so that a squeeze gap is formed extending over the entire width of the combustion chamber. In the region between the valves (6, 7) there extends a further, central squeeze gaps (26) which, in conjunction with the wall of the cylinder head lying thereover, forms a further squeeze gap flow (30) which reinforces the lateral squeeze gap flows (29). By this, the moment of ignition can be further advanced and the temperature peaks, as well as the NOx reduced. It is possible to ignite a very lean mixture having an air excess of 30% and over, and this also keeps the combustion temperature at a low value and hence the production of NOx is lower. The CO emission, as a result of the leaner mixture, is in any case smaller and the CH exceptionally low owing to the complete combustion due to rotation. Test results show a reduction in consumption of 15-20% compared with presently known motors.

Title: Arrangement for contactless distance measurement or angle measurement
Inventor: HALTENORTH HELMUT DR RER NAT
IPC: G01D5/347
Filed: 1986-09-29
Abstract: Arrangement for contactless measurement or angle measurement by means of a scale carrier irradiated by means of light. Fitted along a row (Z) are light sources for light of varying wavelengths. Fitted along a transverse line (Q) are light receivers for light of varying wavelengths. Arranged in front of the row (Z) (in the gap Sp) is the scale carrier, which has a measuring scale which is irradiated by the light sources more or less in row form and takes the form of patterns which are coded in the irradiated region by varying light transmission or light absorption. The wavelength-coded light which is emanated from the irradiated region or pattern and can be received at the transverse line (Q) serves as a criterion for the extent of the movements of the scale carrier. The row (Z) of light sources and/or the transverse line (Q) of light receivers is formed by a module (S, T) with a thin light-transmitting layer (S), which contains at least one geodetic optical element (L, BG). <IMAGE>
Patent DE-3633137-A1 (DE)
IPC: C03B9/40
Filed: 1986-09-30
Abstract: In a process for shaping a gob in order to obtain a hollow glass article by means of an electronically-regulated and hydraulically-propelled level, the process of shaping the gob into a rough or finished product is rationally effected in a predefinable and in particular precisely reproducible manner by the fact that an electro-hydraulic servo-drive is used as a means for driving the level, and that the latter, during at least the practically total performance of the movement, is adjusted in position by means of a closed position-regulating circuit. In a device suited for this purpose the drive device of the level (1) consists of an electro-hydraulic servo-drive and an electronic position-adjusting device for the at least approximately total movement of the level. Preferably the movement of the level in the glass article is also effected at a regulated speed and, ideally, the shaping stage is completed by a pressure-regulated forward movement of the level.

Title: Drive for an electrical switching apparatus
Inventor: SCHMIDT WOLFGANG
IPC: H01H33/56
Filed: 1987-01-26
Abstract: The drive for the electrical switching apparatus has a shaft (6) which is guided in a housing (1) filled with insulating gas. The shaft (6) is held by at least one bearing bush (4) which is arranged in an opening (2) in the housing wall. An annular groove (12) is provided, in order to accommodate a sealing ring (15), on the outer envelope surface of the bearing bush (4). It is intended to be simple to install this drive, despite the use of a cost-effective housing (1). This is achieved in that the bearing bush (4) has on its outer envelope surface a second annular groove (11) for guiding a clamping body (17), and in that a screw (22) is guided in the bearing bush (4), which screw (22) presses the clamping body (17) radially outwards. <IMAGE>
