Patent DE-2531568-A1 (DE)
Title: Compressed gas switch with tubular and coaxial contacts - strikes arc between contacts and supplies flow of sulphur hexafluoride for quenching
Inventor: PRAETSCH RUDOLF DIPL ING
IPC: H01H33/70
Filed: 1975-07-11
Abstract: When the arc is generated during circuit breaking under load, it is blown by a compressed gas stream, preferably of SF6, compressed by a piston (10). It has a turbulence grid on one of the contacts, movable with it, and is in the form of a perforated insulating tube in the gas flow path, directly surrounding the arc space during opening movement. The insulating tube (7) has at its one end in the contact (2) area a dia. (D) corresponding to that of the other contact (1), and forms a slide (8) extending to its free end, which releases, with a delay, the gas flow when the contacts (1, 2) are separated.

Title: Separating protective layers from electrical components - by loosening with solvent contg. glycolic acid and ethanolamine before stripping
Inventor: RUMPF DIETRICH DIPL PHYS
IPC: C09D9/00
Filed: 1975-07-17
Abstract: Stripping off layers from electrical components coated with a protective- or insulating layer is effected by using a fluid, kinetically acting on the laminate after a preliminary treatment is disclosed. Pre-treatment takes place by dipping the components in a solvent bath which starts loosening the coating layers. Solvent is left to act on coating for a given time. Pref. the electrical components are first passed through solvent pre-treatment bath, then through a rinsing bath to remove residual solvent and through a stripping bath penetrated by ultrasonic waves. Protective lacquer- and mineral-contg. layers can be removed from components, e.g. semi-conductors parts, without damaging thin precious metal plated layers. Pretreatment shortens stripping time.

Title: Device for turning and standing lances - partic. in steel works, by tilting on a carriage
Inventor: BUDDENBERG HEINRICH
IPC: C21C5/46
Filed: 1975-08-06
Abstract: The device, used in the removal of probes, oxygen lances, etc., has a frame with clamping elements gripping the lance on the outside that can be swivelled in the vertical plane on a carriage or saddle that can be moved backwards and forwards. The device can partic. be used for repair of steelworks lances when these can be withdrawn without damaging or bending them. The lance requiring repair is lowered, with the help of a crane, through the feeding fixture, the clamping lugs are pressed on to the lance and the lance is stopped by the closure of the feeding fixture. The frame is tilted through 90 degrees by action of the tilting motor and the carriage descends through operation of the motor winch. After repair the carriage moves back to the starting point and through operation of the swivelling motor the frame returns to the vertical posn. The lance is fastened on the crane and brought back to its normal location after release of the locking mechanism.

Title: Spray nozzle for foam reaction mixture esp urethane - has nozzles mounted at periphery of revolving distribution chamber
Inventor: ANDERSSON SVEN OLLE
IPC: B29C44/36
Filed: 1975-08-19
Abstract: A noxxle unit for spraying a reaction mixture into a mould when forming plastics foam comprises a mixer which supplies the mixture to the nozzle unit with a rotational motion. The nozzle unti comprises a distribution chamber, supplied from the mixer and itself equipped with a number of outlet nozzles, each of which is supplied from teh distribution chamber by a duct, arranged near the outer circumference of this chamber. The distribution chamber is circular and the nozzle are pointed in various directions so as to spread the reaction mixture in a predetermined pattern. In a pref. embodiment, the distribution chamber has adome-shaped bottom and an acute-angled edge, from which the passages leading to the nozzles emerge. The nozzles are so arranged as to spray a linear or strip-saped region. The distribution chamber may have an internal projection in the centre of its base to reduce its internal volume, this projection comprising a cruciform channel reaching down to the curved base of the chamber. The outlet from the mixer into the distribution chamber is pref. annular and approximately concentric to the chamber. The noxxles are pref. rotatable in their seatings and have an axis at the outer end which does not coincide with that at the inne end. The mixer pref. contains a rotor, having a pointed end penetrating into the distribution chamber and generally adapted to correspond to the curved opposite inner face of the chamber. The nozzle unit is used esp. for spraying urethane foam mixtures. The centrifugal action resulting from the location of all the nozzles around the periphery of the revolving mixing chamber result in a uniform distribution.

Title: Self loading container lorry - with tipping surface and lifting arm on slider at end of inlined surface
Inventor: KRAPP GERHARD ING GRAD
IPC: B60P1/64
Filed: 1975-11-12
Abstract: The self loading container lorry has a load surface which tips about a rear axis. A slider moves up and down the inclined surface and carries hydraulically operated lifting arms to lift and drop the container off the end of lorry. The slider and arms are more versatile than a winch in that they can lift and slide the container. Also, the difficult operation of moving the end of the container between the ground and the load surface is simpler with the hinged arms. By having a slider the length of the arms can be kept to a minimum thus reducing their weight.
