Patent DE-3928255-A1 (DE)
Title: Biological processing of waste or drinking water - by using fixed or vortex bed reactor contg. packing with hardenable biomass film on outer surface
Inventor: WEIL GERHARD DIPL ING
IPC: C02F3/10
Filed: 1989-08-26
Abstract: Biological processing of waste and drinking water, esp. (de)nitrification of ground and waste water, with a biomass of a gel or polymer with enclosed immobilised microorganisms and/or enzymes uses a packing usable in a fixed or vortex bed reactor, a hardenable biomass film, variable w.r.t. thickness and compsn. is applied to the closed outer surface of the packing before this is charged into a reactor. After consumption of a first biomass film, a new film is coated onto the packing. Packings with film coatings differing in thickness, concn. and/or compsn. of the bacteria or microorganisms may be used at the same time and/or sequence. Nutrients and sources of C and energy may be supplied to the microorganisms or enzymes, through the packing, during the water treatment. ADVANTAGE - Water processing is quicker and more effective.

Title: Washing program for drum type washing machine - with specific changes from high to slow speed in both directions
Inventor: ZINKANN PETER DR
IPC: D06F23/02
Filed: 1989-10-06
Abstract: A new washing procedure has been devised for program controlled washing machines with at least one rib in the drum which acts in both directions of rotation as a scoop for the liquid.

Inventor: KAADEN JUERGEN DIPL ING
IPC: H04N7/01
Filed: 1989-12-09
Abstract: A video-signal store is used, in particular, to convert the vertical frequency of a TV signal from 50 to 100 Hz or the line frequency from 16 to 32 kHz. The video-signal read-out operation then takes place in a shorter time than the recording operation. The aim of the invention is to provide a simple control circuit for the read-out operation. Resetting the store (M) at the end of the read-out operation is carried out using a vertical synchronizing signal split off from the signal which is read out.

Title: Pivoted ramp - to tip sewage from tank perimeter into surrounding channel while restraining remaining layer
Inventor: KONRADI OSKAR
IPC: B01D21/24
Filed: 1990-01-08
Abstract: Suspended from the edge of a sewage settlement tank is a channel to receive floating sludge. Pivoted to the channel edge is a ramp. When the free ramp is raised, e.g. by a cable, adjacent sludge collects on the ramp surface and slides down into the channel. Ramp surface is permeable to water but not sludge. The engageable ramp end flange has a downward extension which passes through the sludge layer even when the ramp is in raised position. The ramp may be divided into independent sections round the tank perimeter. ADVANTAGE - Considerably larger area of sludge are  removed singly.

Patent DE-4111898-A1 (DE)
Title: Recycled paper processing - includes taking part of material from charge from dissolving to sorting stages to be sorted while the dissolving stage is recharged
Inventor: SCHWEISS PETER
IPC: D21B1/34
Filed: 1991-04-12
Abstract: To dissolve recycled paper in a discontinuous and periodic operation, where the material has a significant content of insoluble matter such as of plastics and film, at least 5% of the material from the dissolving stage is diverted from the zone between the entry side of the sorter and the sieve during two-thirds of the emptying phase and max. the first part of the emptying phase, and passed to a collection container. While the dissolving stage is being refilled, after the charge has been dissolved, the diverted and collected fraction is sieved through the sorting unit. Material is diverted from the zone between the entry side of the sorter and the sieve at a rate of 5-10% of the incoming material, through the pump action of the rotating wheel and the tangential outlet near it in the housing leading upwards and out. No material is diverted at the start of the emptying phase from the dissolving unit. To divert material from the sorting stage, the running wheel rotates at least 50% faster than when in the start phase of material feed. The material is led from the sorting stage (3), following the dissolving unit (1), by periodically blocking the branch channel (12) every 20-80 secs. The block (13) moves to and fro between a fully-closed position and a fixed one-time open position where the channel cross section is at least 70% of its full size. The sorting action of the sieve (5) is set to take max. 10% of the full capacity, when the diverted material is passed through. The sieve (5) openings at the sorting stage (3) have a dia. of 4.5-6.5 mm. The upper edge of the sorting stage (3) is below the lowest point of the outlet from the dissolving stage. The collection container (7) for the diverted material is at an level. The entry tube to the sorting stage is pitched at an angle of 20-30 deg. to its end wall, in an upwards direction, from the centre of the end wall. ADVANTAGE - The method prevents stoppages and clogging at the sorting stage.

Title: Underwater projectile launcher - provides projectile directional stability on exit from firing tube
Inventor: BUGIEL GEORG
IPC: F41F3/07
Filed: 1991-04-19
Abstract: An underwater weapon (11) has a tube (12) for firing a slender high velocity projectile (13) which has a tip (14) and casing (21) of full cavitation geometry over its length contained in the tube (12) and which is retained by a full calibre guide body (28) provided with points of weakness. The rear end of the guide body (28) and the projectile tail (22) rest against a thrust retaining plate (32) located in front of the propellant charge (26), axial motion of the plate (32) out of the tube outlet (25) being retarded by a radially acting deformation device (37) which temporarily seals the tube outlet (25) against the propellant gas blast. ADVANTAGE - Directional stability perturbations are reduced during exit of the projectile tail from the firing tube so that target hit precision over increased distances is increased.

Patent DE-4125843-A1 (DE)
Inventor: MAAS JOACHIM DIPL ING
IPC: B60T11/28
Filed: 1991-08-03
Abstract: The invention concerns a drive-slip-controlled brake system in which, during-slip control, a pump aspirates pressurized-fluid from a reservoir (15) through the pressure chamber of the master cylinder (1). The invention proposes that the brake-pressure generator be fitted with an additional connecting line (18) between the pressure chamber (3) and the pressurized-fluid reservoir (15) and that a non-return valve (13, 14) which opens in the direction of the pressure chamber (3) be fitted in this line (18). As a result, the functioning of the master cylinder (1) is completely unaffected by operation of the brakes while, for drive-slip control purposes, a greater flow cross-section is available between the pressurized-fluid reservoir (15) and the aspiration side of the pump, thus permitting a higher pressurized-fluid flow rate.
