Title: Single stack cartridge magazine - has separate sprung walls with turned-over edges at open end (OE 15.11.76)
Inventor: MUELLNER FRANZ
IPC: F41A9/65
Filed: 1976-12-14
Abstract: Cartridge magazine has single stack, is intended mainly for sporting guns, and consists of bottom part (1), longitudinal walls (2) and lateral walls (3). The longitudinal walls (2) are fitten with leaf springs (7), which extend only over part of the magazine length and are provided at the top end with turned-over edges (4) functioning as retaining lips for the uppermost cartridge.

Title: Disinfecting water with ozone and halogen esp. bromine - charged on a fine-grained active carbon filter layer and sheathed with plastics
Inventor: SKIRDE GERHARD
IPC: C02F1/78
Filed: 1977-02-22
Abstract: Prepn., esp. disinfecting of water with O3 and with >=1 halogen, esp. Br2, introduce into water, takes place by using halogen-charged, esp. fine-grained active C as filter-layer, and adding an O3-contg. gas to the water in filter inlet zone. The filter layer of highly halogen-loaded active C grains, having delayed halogen delivery, is prepd from halogen-charged active C grains sheathed with a halogen-impermeable plastics coating which can be split open by O3. The coating pref. consists of silicone rubber, epoxy resin, polycarbonate, polyvinyl carbazole, PTFE or a similar material. Uses include disinfecting of medical massage baths and drinking water. Halogen transport and handling is simplified and made safer. Halogen-charging can take place in halogen-prodn. industry. The loaded active C particles can be stored indefinitely in plastic bags. In use, O3 oxidises Br2.O3 excess reacts with active C to form CO2. Burning up of C releases further Br2. The bath is easily kept at desired redox potential of 650mv and O3 content 0.1ppm in water and 0.01 ppm in air.

Title: Radiation proportional counter with large window - has several anode wires each connected to separate rate meter to minimise noise signal
Inventor: MAHNAU HEINRICH
IPC: H01J47/06
Filed: 1977-03-02
Abstract: Proportional counter of large area is intended for measuring radioactive radiation and comprises a gastight housing with a window in one face. Two or more anode wires are mounted adjacent to the single window of one housing, each anode wire is connected to a separate, external rate meter with complete electrical separation between the circuits. Each anode wire thus constitutes a completely independent proportional counter, whereas the configuration of all the anode wires constitutes a single large area without dead peripheral regions between separate parts of it. Used for highly sensitive radiation monitoring, typically where the window area of the counter housing is 600 cm.2 or more. By having two or more separate anode wires, each with its associated rate meter, mounted in this single area, the signal reading is doubled for a given background effect and consequently the resolution is considerably improved.

Title: Vehicle-sensitive seat belt blocking mechanism - has inertial mass mounted to react to vehicle movement in any direction
Inventor: KOMOSSA HORST DR ING
IPC: B60R22/40
Filed: 1977-07-22
Abstract: An inertia mass-operated seat belt blocking mechanism reacts to sudden acceleration or deceleration not only in travel direction, but also in vertical direction. The relevant feature of the design is that the inertia mass is kept in the neutral position by a spring and the suspension of the mass is such that it can yield to impulses from any direction. The mechanism consists of pendulum(14) with arm(14a) and mass in form of disc(14b). The disc(14) rests in a nest-like enlargement of a spiral spring(15) which keeps the pendulum in its neutral position. The arm(14a) is cranked so that the centre of gravity(S) of the disc(14b) is positioned eccentrically to the rest of the arm. The other end of the arm(14a) is fitted with actuating disc(14c) the tilting movement of which lifts the swinging arm(17) pivoting around the fulcrum(16) inducing the blocking action with the ratchet wheel(6).
