Title: Machining workpieces made of brittle materials
Inventor: BRANDT GEORG
IPC: B24B27/00
Filed: 1983-01-28
Abstract: According to the invention, the plane side cross-grinding process is used to machine workpieces made of brittle materials having a minimum Vickers hardness of 5000 N/mm<2>. The present invention facilitates the grinding of plane surfaces with grinding discs according to the design principle of known cup wheels such as those which have hitherto been used in side grinding, but with completely unforeseeable advantages. According to the present invention, a plane surface to be machined is subjected, without any feed motion, to the action of a rotating grinding wheel which advances and is of the cup-wheel type, the plane grinding face of the grinding wheel partially, or preferably completely, covering the extent of the surface to be machined and being in one piece or built up of segments. According to the invention, far higher grinding abrasion than hitherto is achieved, with optimum surface properties.

Title: Turnstile for forming a passage for persons
Inventor: EBERLEIN HERBERT DIPL ING
IPC: E06B11/08
Filed: 1983-02-10
Abstract: In turnstiles, which form passages for persons, it can never be completely avoided that children who fiddle about in a playful manner with turnstiles become caught between the turnstile struts and parts of the adjacent enclosure. The invention therefore proposes a turnstile (1) which has a radially acting clamping device (16) which is located in a coupling piece (10) which is connected to the return lock (3), the clamping device (16) being active indirectly or directly in relation to the vertical pipe (2) or the sleeve (4). 
<??>The turnstile, which is relatively easy to manufacture, can be rotated backwards in the event of danger, by exerting a given force.

Patent DE-3311242-A1 (DE)
Title: Magnetoresistive head
Inventor: HAYAMA NOBUYUKI
IPC: G11B5/39
Filed: 1983-03-28
Abstract: The magnetoresistive head has a magnetoresistive (MR) element which is located on a substrate of insulating material and has at least one linearly extending, parallel undulation. A biasing device serves for deflecting the current direction through the MR element, by an angle of at least 30 DEG  to a maximum of 60 DEG  with respect to the limitation which exists between a projection and a depression and forms the undulation. On account of the dimensional anisotropy of the MR element, the angle between the magnetisation and the current in the MR element is determined by the undulation pattern.

Title: Automatic turning valve actuated by pressure medium, in particular for reversible ploughs, rockers, pumps or the like
Inventor: SCHNEIDER WALTER DIPL ING
IPC: F15B11/15
Filed: 1983-05-21
Abstract: Automatic turning valves actuated by pressure medium, in particular for reversible ploughs, rockers, pumps or the like, with a reversing valve through which pressure medium flows and which controls the flow of pressure medium to the actuating cylinder for the reversal movement, are to work as a function of the flow rate or flow quantity of the pressure medium, it being possible for the end positions of the piston to be exactly determined so that a virtually instantaneous, smooth operation independent of the system pressure is effected. This is achieved by the quantity of pressure medium flowing to the reversing valve being measured and by the reversal being effected as a function thereof when the zero value is reached.

Patent DE-3325068-A1 (DE)
Inventor: BUCHHOLZ HORST
IPC: C25D13/14
Filed: 1983-07-12
Abstract: The coating of hollow bodies open on one side, such as cans, with paints such as clear or pigmented lacquers, enamels or the like give rise to difficulties for a continuous one-step operation. In the coating process, the cans are first washed, then coated inside and outside, dried and optionally printed and again dried. The difficulties of a continuous one-step operation are solved by utilizing an electro-dipcoating bath and by employing a process wherein the cans are immersed in the electro-dipcoating bath vertically and with the closed bottom downward into the bath, filled from the top with the bath liquid and during the raising from the bath, tilted so that their opening is pointing downward. The cans may also be forcibly immersed with their opening below the surface of the bath for filling with the bath liquid by means of a filler device. Uniform coatings of a plurality of hollow bodies in a continuous one-step coating process are thereby achieved.
