Patent DE-2135545-A1 (DE)
Title: Cleaning welding burners - using blasts of air and parting agent-air mixt
Inventor: DAMMERS CLAUS
IPC: B23K9/32
Filed: 1971-07-16
Abstract: Process is carried out after a delay to allow a weld seam to cool and comprises passing an air stream at high speed through the burner; immediately afterwards, passing a parting agent-air mixt. blast; and then, briefly, passing a shielding gas stream to displace the air in the burner. The process is simple and rapid, and the air stream aids burner cooling so that water cooling is not reqd. The process is controlled by time switches.

Title: Alluvial filter with vertical elements has cakes stabilised - by horizontal plates with perforations to key cake in position
Inventor: KUEHTREIBER FRANZ DIPL ING
IPC: B01D29/00
Filed: 1973-09-25
Abstract: A device for stabilising the filter cakes on alluvial filters, where the filter elements are vertical, comprises substantially flat, horizontal sheets or plates which support and subdivide the filter cakes; these plates possess perforations and the plates extend sufficiently far horizontally to project beyond the maximum thickness of the filter cake. In a preferred embodiment, where the filters are of candle-type, the elements are perforated rings surrounding each candle and having an external dia. sufficient to project beyond the filter cake. In a variant of this arrangement, the individual horizontal plates are of progressively decreasing dia. above each horizontal element, giving a tapering effect in each subdivision between plates. The supporting plates prevent parts of the filter cakes from easily breaking away.

Title: Vibrating massage device with large axial movement - has internal coil-up system and compression spring tensioned by this process
Inventor: SCHMIDT ERHARD
IPC: A61H23/02
Filed: 1974-08-01
Abstract: A massaging device with axial vibration direction is constructed to allow length axial movements and has its inner diameter smaller than the length of axial motion produced. The axial motion is produced by the coiling up of a traction cable on a blade rim or by means of the action of a gearwheel on a gear rack. The extent of the motion is given by d PI. Coil up of the traction cable tensions a compression spring which is mounted within the housing and which is released by a device which senses when the cable has been fully coiled, and allows the compression spring to force the end of the massage device outwards. This process is repeated rapidly.
