Title: Call routing system for PBX subscribers - has controller determining acoustic signal input to addressed station with comparators to effect control on ring-to-tripping conversion
Inventor: HELLMIG KLAUS ING GRAD
IPC: H04Q3/545
Filed: 1978-08-30
Abstract: The switching system reduces undue loading of contacts during the cutting-in process. The system allows a call to be routed to a subscriber in a PBX, via instructions from the central controller, by timed, controlled connection and disconnection of the acoustic signal to the signal path of the respective, addressed subscriber station or addressed connecting link. Comparators in the central control unit allow the control instructions required for connecting through in a connecting link and/or via the coupling point contacts of a coupling network, to become effective only after the ringing action is converted to a tripping action.

Title: Ceramic moulding with rose or pink colour - is made from dry mixt. contg. zirconia, iron chloride, and strontium nitrate
Inventor: GRIMMEL SIMON
IPC: C09C1/00
Filed: 1978-10-21
Abstract: The mouldings are made from a mixt. contg. ZrO2 or cpds. forming zircon, plus silica, alkali minerals, alkaline earth nitrates, and iron chlorides which form iron oxides when heated; and the mixt. is calcined at above 700 degrees C. The pref. alkaline earth nitrate consists of strontium nitrate used in the amt. of 0.02-0.1 mole per mole of ZrO2. The disadvantage with conventional ceramic mixts. employed to produce a rose colour is that they do not produce a consistent colour over a wide range of baking temps. A uniform rose colour is obtd. The new mixt. can be prepd. without the addn. of water, so it is not necessary to use a soln. of an iron salt, and the energy previously required for evapn. of water prior to calcining is eliminated.

Title: Optical device to measure surface position - uses laser diode spot source on surface which is sensed by height
Inventor: LIETAR CHRISTIAN
IPC: G01B11/06
Filed: 1978-11-18
Abstract: An optical measurement device for measuring the position of a plane light scattering surface of an object along a line normal to the surface has a laser diode source forming a light spot on the surface which is sensed by the measurement device. It enables rapid high accuracy measurements when the surface vibrates and on very sensitive surfaces. The light beam (9) axis is slightly inclined to a reference direction (15) and the measurement device (3) is directed approximately perpendicular to the beam axis. Photodetectors (13) placed in the measurement lens (11) image plane (12) sense the height of the spot (10) image. For measuring the thickness of plane parallel objects the objects (4) are fed past the source and measurement device whilst continuous measurements are taken. The beam inclination angle is between 10 and 20 degrees, esp. 15 degrees.

Patent DE-2903010-A1 (DE)
Title: Constant force suspension for pipeline - uses cam and coil spring arrangement to provide constant torque on shaft
Inventor: LUDOLPH SIEGFRIED
IPC: F16L3/202
Filed: 1979-01-25
Abstract: A section of the pipeline is attached with a tie-rod to a suspension bracket. The bracket is supported by a strap which runs over a disc. The disc is mounted on a shaft which also carries a cam. A strap which is attached to the cam runs over a guide roller and is attached to a coil spring. When the force of the spring increases, the radius of the cam reduces, so that a constant torque is exerted on the shaft. A constant pull will therefore be exerted on the first strap.
Patent DE-2905578-A1 (DE)
Title: System which removes swarf from holes bored in ferromagnetic pieces - using AC magnetic field to agitate swarf and DC field to attract it
Inventor: SCHOENING PAUL ING GRAD
IPC: B23Q11/00
Filed: 1979-02-14
Abstract: The swarf-removing system consists of a magnetisable pin or rod (15) inserted into the hole and magnetised to attract swarf in the hole to it. The pin or rod is then removed from the hole bringing the swarf with it. Whilst the pin or rod is being inserted into the hole, an ac magnetic field is generated in the region of the hole by passing an alternating current through a coil (16). This ac field causes the swarf particles in the hole to vibrate such that they are picked up by the pin or rod more readily and are less likely to drop off as the pin or rod is withdrawn from the hole. The amount of swarf left in the hole after the pin or rod has been withdrawn is therefore greatly reduced.
Patent DE-2908933-A1 (DE)
Title: Hardened steel balls exposed to vibrating hammer plate - to create residual compressive stresses, esp. in balls employed in ball bearings
Inventor: WERNER GUENTHER ING GRAD
IPC: C21D7/04
Filed: 1979-03-07
Abstract: The stresses are provided in the surface zone of the balls, and are created by allowing the balls to roll down the sloping surface of a hard, flat plate. Above plate is an impact plate, which is parallel to plate, and which is vibrated at high frequency to impose repeated hammer blows on the balls, thus creating the desired compressive stress. The pref. machine uses a plate suspended by a spring-loaded guide fitted on each corner of the plate; and two driven shafts fitted with eccentrics control the vertical amplitude of vibration of plate. Plate carries baffles so the balls cannot roll in a straight line down this plate.

Title: Spot welding gun - has pivoted bracket moved by power cylinder to clear workpiece
Inventor: VOLLMER EWALD OSKAR DIETER
IPC: B23K11/31
Filed: 1979-05-04
Abstract: Spot welding gun. esp. for use in flow lines of the motor car body production has the upper welding electrode attached to a bracket which can be swivelled relative to a guide shaft inside a mounting block. At the end opposite to the welding electrodes, a double-acting horizontal power cylinder is attached below the double-acting vertical welding cylinder, to turn the bracket through an angle. The welding gun operates reliably and with little noise. The turning of the welding gun clear of the workpiece is independent of the clamping movement and an interlock can ensure that clamping is possible only after the welding gun has been returned to the welding position.

Title: Scenic aids for manually manipulated puppet theatre - has microprocessor-controlled storage units for lighting and sound effects
Inventor: HOESCH GUENTHER
IPC: A63J5/00
Filed: 1979-10-22
Abstract: The method for providing the scenic events of a manually operated puppet theatre with concurrent illumination and sound effects includes memory elements which hold fast instruction data to control light switches, and other memory elements which store sound effects in analogue or digitised form. A time alignment or synchronising control unit ensures the reproduction of all scenic elements in the correct mutual relationship, and aids to steer the puppets in accordance with encoded timing or progression signals also provided by the recording system. The synchronising progression signals may be generated consecutively and related to certain scenic moments of the puppet play; they are the same coordinating signals which call up the stored lighting and acoustic sound effect signals and cause them to be fed to the requisite power switches and acoustic transducers (loudspeakers). The memory elements may be either a magnetic tape with several data tracks and magnetic read/write heads, or a microprocessor controlled digital signal storage circuit which converts the encoded signal sequences into a number of simultaneous or sequential illumination switching instructions and/or special sound effects.

Title: Pot-shaped contact for vacuum switch - keeps arc on contact face of contact ring by magnetic field from radial current components
Inventor: GEBEL RUDOLF DIPL ING
IPC: H01H33/664
Filed: 1979-11-26
Abstract: The pot-shaped support (4) is connected at its centre to the connection conductor (8) and has a contact ring (12) on its opposite face. The support has inclined slots (10) distributed around its inside face so that the current flowing always has a component moving at an angle to the axis (18) of the contact so that the arc rotates. The contact ring may be made of a sintered material containing copper and chromium or of another material suitable as a contact. The current in the contact is such that base of the rotating arc remains on the contact face. The radial current components produce a magnetic field that keeps the arc on the contact face. The arc is not subjected to forces acting radially inwards and outwards and therefore cannot migrate into the recess in the pot. The sloping edges of the contact ring prevent the arc appearing in regions where it is not subjected to the stabilising magnetic fields produces by the radial currents. (The contact pressure is also increased as result of reducing the contact surface area).
