Title: Removing material from bar screen of sewage treatment plant - by creating downward flow to flush material into perforated cage
Inventor: REPPERT HERBERT
IPC: E02B8/02
Filed: 1977-03-15
Abstract: A bar screen for channels in municipal sewage plants is flushed free by creating a downward flow. This moves any matters such as rags, sticks and garbage into a perforated cage in a sump. After lifting the bar screen up by a winch, the cage can be raised and emptied. The bar screen in the sewage channel has partly horizontal bars and partly inclined against the direction of flow. It is surmounted by a baffle plate. The sole is open to allow access to a perforated cage to collect the matter screened by the bars. A concrete partition creates a downdraught which keeps the bar screen free. This saves the attendant from unhygienic and unpleasant manual cleaning of the bar screens.

Title: Visual or acoustic blown fuse indicator - uses incandescent or glow lamp, or acoustic device instead or in addition to LED
Inventor: SCHMIDT ULRICH
IPC: H01H85/32
Filed: 1977-05-28
Abstract: The light emitting diode is directly or indirectly parallel-connected to the fuse. The drop increase over the fuse, when blown, triggers a current flow through the diode, thus energising its light emission, as in 2551447. Instead of, or in addition to the diode the indicator uses an incandescent and/or glow lamp and/or an acoustic warning. The lamp or the acoustic warning (4) is in series with a transistor (3) and possibly a resistor (5) between both current supply terminals. An ohmic voltage divider (8, 9) is in parallel to the load (11) while its tap (10) is coupled to the transistor base. With the fuse (7) intact the transistor blocks, but becomes conductive when it is blown, thus supplying the indicator devices.

Title: Prodn. of down and/or feather and synthetic fibre filling - for quilts etc. using melt spun fibres of various diameters and lengths
Inventor: SCHNAUSE ROLF
IPC: B68G3/02
Filed: 1977-08-24
Abstract: In the prodn. of a filling for beds, quilts, cushions, sleeping bags etc. from down, feathery down and/or half down, feathers and synthetic fibres, synthetic fibres are mixed with the feathery constituents. The synthetic fibres pref. are produced by breaking up a spinnable polymer melt (at 300-365 degrees C) emerging from a tube with a hot gas (at 300-400 degrees C), pref. so that it is drawn out to 1.1-3.6 my fibres by the gas stream. Pref. the synthetic fibres consist of polyaminoundecanoic acid ("Rilsan"; RTM) cyclohexane-1,4-dimethyl terephthalate ("Vestan"; RTM) or low pressure polyethylene. They are blown into the mixing chamber by the gas stream, opt. intermittently, and spread by high tensions. The synthetic fibres not only act as extender but also improve certain properties and also give a new property, the prodn. of electrostatic charge by friction, which is useful for treating rheumatic and arthritic patients. The process employs only one (continuous) procedure, instead of the 8 stages used formerly, and the prod. has a higher bulk.

Title: Therapeutic substances application - using ultrasonic bursts to improve penetration into tissue
Inventor: MAUSER RUDOLF
IPC: A61M37/00
Filed: 1977-12-17
Abstract: A device for the locally limited application of therapeutic materials through the surface of living bodies or organs consists of a conventional ultrasonic vibrator applied to the surface with a coupling medium between vibrator and surface; this coupling medium contains the therapeutic materials to be applied. The sonic energy is applied in pulse packages. The pref. frequency range is 750-850 kHz. Pref. the width and the sequence of the pulse packages can be varied to suit the particular object to be treated. By applying the ultrasonic energy in a pulsed instead of a continuous sequence, an asynchronous vibration in the tissue can be set up, causing penetration of the boundary layers when the next pulse packet follows and consequent diffusion of the substances through the organ. The depth of penetration and the power density are preselected solely by the pulse packet length (burst) and the repetition rate.

Title: Voltage transformer esp. for TV receiver - supplies line deflecting current direct from transformer primary or secondary windings
Inventor: STUEDEMANN BERND ING GRAD
IPC: H04N3/185
Filed: 1978-04-10
Abstract: The controller switches the output transistor at line frequency. The collector of the transistor is connected in series with the primary winding of the transformer. The winding load inductance, capacitors and diodes create a magnetic flux varying in sawtooth form. Secondary windings provide the receiver operating voltage, the deflecting current and the high voltage. The deflecting current may alternatively be taken from the primary winding. Drawing the line deflecting current direct from the transformer eliminates the normal horizontal sweep circuit, thus reducing cost and complexity.
