Title: Industrial robot with arm having four degrees of freedom - uses harmonic drive transmission to control movement of joints
Inventor: EPP PETER
IPC: B25J9/04
Filed: 1977-04-22
Abstract: An industrial robot for handling e.g. crankshafts, is mounted on a turret (1) which can rotate about its vertical axis. The arm (2), which is able to rotate about its horizontal axis (7), houses a ball screw drive (3) which moves the extension (5) in the horizontal direction (III) when driven by the motor (4). The arm (2) also houses the motors and associated harmonic drive transmissions which rotate the extension (6) about the longitudinal horizontal axis (IV) and about the radial axis (V). There is also a motor which rotates the disc (15) which carries the tool or workpiece about the axis which is parallel to the axis of the extension (5). The disc (15) thus has four degrees of freedom.

Title: Heatable and coolable press mould - made of high compressive strength glass for thermoplastic video discs and other plate-like information carriers
Inventor: SCHAFFNER HERMANN
IPC: B29C43/00
Filed: 1977-10-25
Abstract: Plate-like information carriers, made of thermoplastic materials, for high-density optically scanned video or image discs, are produced in presses with moulds in which a cooling and a heating system are incorporated. The block mould is made of glass with a high compressive strength in which ducts for a coolant are enclosed. Heating wires are embedded close to the ace which carries the matrix with the surface structure for the information carrier. The glass surfaces can be ground to a surface roughness of 0.2 u which results in lesser scanning errors than when steel moulds are used.

Title: Filtration of suspensions, esp. for drinking water - by filter bed in suspended element permeable all round
Inventor: DISSELBECK DIETER DIPL ING
IPC: B01D24/04
Filed: 1978-06-19
Abstract: A filtration medium is filled into a sack-like, suspended element forming part of an arrangement for the filtration of suspensions. The element is permeable to fluids all round, and is formed by a fabric woven from a material which is chemically and mechanically highly resistant. The suspension is delivered via a pipeline which opens into the middle of the element and dips into the filtration medium. The penetration of the pipe outlet is adjusted so that the height of the filter bed below it is at least half the dia. of the filter bed. Used to make the filtration more efficient and to provide technical conditions which are more favourable. The filter bed does not choke so readily and the medium does not have to be changed so frequently. Backwashing requires less water and when the filter bed has to be changed it can be taken out as a unit.

Title: Quick-action HV switching mechanism - has two energy stores connected via holes to chamber containing drive piston
Inventor: KLINGER FRIEDRICH DR ING
IPC: F15B15/22
Filed: 1978-11-28
