Title: Staple fibre cutter - with self-sharpening blades
IPC: D01G1/04
Filed: 1972-02-10
Abstract: The blades in a cutter, cropping staple fibres from a continuous tow of chemical filaments, in which the strand of fibres held by suction to the perforated surface of a rotating drum is sheared by the circular blades of the spinning cutter head, has fitted to it abrasive blocks, which may rotate, in contact with the edges of the cutter discs. As the friction between fibre and blade slightly turns the disc each time it cuts so that a new cutting point is constantly being presented to the moving strand, a corresp. segment of the blade is sharpened, keeping the edge as new until it is finally too small to be of service. The life and efficiency of the cutters are increased.

Title: Coloured light mixing system - achieves lighting effects for television and theatre, by programmed mixing of 3 primary colours
Inventor: KOSMAHL REINHOLD
IPC: H05B37/02
Filed: 1973-08-03
Abstract: A wide range of lighting effects is achieved by combining the three primary colours of blue, red and green. The desired lighting effect is determined and a programme is set-up on a plug-board matrix on the control unit. The amplitudes of the three primary colours are controlled by varying the supply voltage to a number of oscillator circuits. A number of different oscillator frequencies may be preset on manually variable potentiometers on the control console. These different frequencis are then selected by programming the matrix input. In addition the switch-on and switch-off periods of the oscillators may be adjusted to provide a variable mark-space ratio without changing the particular frequency.

Title: Vacuum cleaner with dust filter and locking element - has spring-operated safety means preventing functioning without filter
Inventor: OBBELODE WILFRIED
IPC: A47L9/19
Filed: 1974-02-14
Abstract: The dust filter is held in the vacuum cleaner by a locking element which is guided positively in the vacuum cleaner at right angles to the direction in which the filter is inserted. The locking element itself has a nose projecting into the guide of the filter and a locking stud which prevents the lid from being closed if the filter is not present. The locking element which is resiliently mounted in a guide has a cylindrical guide member which is hollow and contains a helical spring. When the dust filter is inserted in its guide, its leading flange presses the nose of the locking element against the spring so that the locking stud is pressed to one side and the lid can be closed.

Title: Etching process for substrates e.g. printing plates - uses radn. sensitive layer contg. photodegradable cpd. yielding cpd. which etches substrate
Inventor: ARNOLD GUENTHER DIPL PHYS
IPC: G03F7/004
Filed: 1974-04-05
Abstract: Substrate surfaces of structures are etched by using a radiation-sensitive layer contng. a cpd. (I) which undergoes photolytic decompsn. under the influence of radiation to release a reaction product which etches the substrate material in the region of the surface, and the amt. of radiation falling on the layer corresponds to the profile depth of the substrate to be etched. Process overcomes the problem of estimating exactly when to the etching process should be interrupted to give optimum structure, as is the case with known photochemical etching processes. Process is esp. useful for making printing plates and semiconductors.

Title: Aluminium sheet segmented silo tank - with vertical sheet edges extended to flanges for screwing together on site
Inventor: KOLBE RUDOLF
IPC: B65D90/08
Filed: 1974-07-17
Abstract: The large scale silo tank, is assembled from segment sheets, interconnected along their vertical edges. These vertical edges (10, 10') cross over into a flange unit (11, 13, 11', 13'), set back from the tank, to form a connecting plane (40), where they are held together by screw connections (30, 35).
