Title: Processing household rubbish, communal and industrial sewage, etc - for protection of the environment and recovery of valuable prods
Inventor: LIPPE FRITZ
IPC: C05F7/00
Filed: 1974-06-28
Abstract: Household rubbish and/or similar material is pulverised and expanded with industrial effluents and/or sewage sludge heavy matter such as sand, pieces of metal, etc., being allowed to settle out. The fluid is then subjected to shock loading by electrical discharges, so as to reduce it to a cellular condition as far as possible, and filtered to a residual humidity suited to further biological treatment. The filtered mixture is changed by the micro-organisms into a humus whilst the filtrate is also converted by bacterial action into biologically irreproachable water. During processing, part of the saturated water may be drawn off for biological treatment and its volume replaced by fresh water, and during the electrical discharge treatment, oxidising agents in gaseous, fluid or dissolved form are added. Waste and sewage can be disposed of in an economically practical manner without harm to the environment, and valuable substances can be recovered for reintroduction into the natural cycle.

Title: Rapid charging cct for batteries - has battery voltage detector to switch off power when charging is complete
Inventor: BOREJKO STEFAN
IPC: H02J7/00
Filed: 1974-08-28
Abstract: The circuit cuts off the power supply when the battery is fully charged. The circuit is fed with half- or full-wave rectified single phase power (5) which is switched by a thyristor (7). As soon as the anode voltage exceeds the battery (6) potential, the thyristor is triggered via resistors (8, 16) between gate and anode, and current flows through the battery. A second thyristor (9) is connected between the gate of the first thyristor and the neutral rail and is triggered when the battery voltage reaches the charged value as set on a voltage divider (12, 13). The gate of the first thyristor is thus blocked and charging ceases. The second thyristor (9) is maintained in conductive, when the applied sine half wave voltage reaches zero.

Title: Projectile fuse charging system - uses projectile skin friction and initiates fuse on contacting metallic target
Inventor: TRINKS HAUKE DR
IPC: F42C11/00
Filed: 1974-12-23
Abstract: The device for generating a current pulse to the fuse of a projectile uses electrostatic charging of the projectile skin during flight. The arrangement is discharged on meeting a metallic and conducting target. This fuse is insensitive against objects such as rain, trees and non-metallic obstructions. The projectile may meet the target at any given angle or attitude without detriment to the fuse operation which n eed not be in projectile nose. The projectile accommodates a solenoid in which is generated a current pulse when projectile is suddenly discharged. This pulse actuates a suitable triggering stage which initiates the actual fuse and gives a starting signal for initiating the ignition process. The triggering stage can be a suitable IC element or a thyristor with a monostable multivibrator.

Title: Foam fire-extinguisher providing an extra-rich stream of foam - with central high-speed jet carrying foaming outer layer
Inventor: EGGERT UWE
IPC: B05B1/02
Filed: 1975-05-03
Abstract: The fire-extinguishing fluid passes upward through a wire-mesh screen (11) where it is converted to foam. The usual uniform screen is replaced by a two-part screen, whose central region (7a) produces a high-speed jet of foam while its outer ring (7b), being of a finer mesh, produces foam of greater density but less velocity which, however, rides forward on the central jet. The finer screen is produced by placing a second layer of the coarser mesh diagonally across the first; a supporting screen (7b'), wholly of the coarser mesh, may be placed at a little distance behind the main screen.
