Title: Monostable flip-flops for short pulses - are used for control of pump motor of searchlight washing installation
Inventor: RATZEL RUEDIGER
IPC: H03K3/284
Filed: 1974-06-29
Abstract: There is a control transistor and a switching transistor, and a switch for switching pulse tripping. The control transistor base is connected to the tapping of a voltage divider connectable to the voltage source; its emitter voltage is determined by charge voltage across a capacitor, maintained at a given value during the stable state of the flip-flop. It is increased during the unstable state through a charging circuit also connectable to the voltage source. A resistor is in parallel with a diode of the same polarity as the control transistor base-emitter path, and is connected to its emitter; this parallel circuit in series with a further resistor is in parallel with the capacitor; the voltage source is connected to this resistor through a switch.

Title: Flexible holding bracket for practice targets - has fork shape for feeding continuous target strip without damage
Inventor: STIEGLER HUBERTUS
IPC: F41J1/10
Filed: 1975-01-22
Abstract: The flexible holding and guide bracket for strip shaped firing practice targets is placed into a frame which leaves the target area free. The bracket is used instead of a readily damaged target cassette for facilitating the threading of the new target. It also ensures reliable guiding of the target strip which is moved on after every shot to present a new target. This facilitates target change especially under competitive shooting with air guns. The spring steel fork shaped bracket has a horizontal arm (2) which is to be inserted into the target holding fork. This arm has a vertical guide (3) held in the target holder hole and fork arms (4, 5) have outwards bent horizontal parts (6, 7).

Title: Heating or cooling cylinder with spiral passages - simplified manufacture by corrugation of inner cylinder reduces cost
Inventor: RECKERMANN WILHELM
IPC: D06C15/08
Filed: 1975-02-04
Abstract: The outer shell of the cylinder (1) is made from weldable steel tube. The inner cylinder is formed from ductile, weldable sheet 1.2 to 1.6 mm. thick, which is corrugated by rolling and then formed into a spiral, which may be of double-helix form. The abutting edges of the spiral are then welded to produce a cylinder of such a diameter that it may be pressed into the outer tube. The corrugations serve as the flow passages for the heating or cooling medium which is fed in contra-flow fashion via hollow shafts (5 and 6) mounted in the welded-in end plates (3 and 4). The inner cylinder may alternatively be made from injection-moulded or thermo-moulded plastic material.

Title: Omnidirectional loudspeaker unit with identical speakers - has speakers systematically arranged inside suspended spherical housing beneath latters equatorial plane
Inventor: SEEGER FERNANDO
IPC: H04R1/40
Filed: 1975-02-13
Abstract: The loudspeaker unit has two or more series-coupled loudspeakers in a common spherical housing. The speakers are arranged symmetrically about the axis that passes at right angles through the centre of the equatorial plane of the sphere and the axis of each speaker is at 45 deg. to this equatorial plane -- i.e. the speakers lie on the underside of the sphere. The top half of the sphere carries the connector assembly. The three loudspeakers have the same impedance -- pref. 8 ohms. The advantage of the unit lies in its accommodating any number of loudspeakers and in having omnidirectional properties.

Title: Double-chamber toilet cistern - is divided into two unequal halves with separate outlet valves
Inventor: SCHUERGER GERT
IPC: E03D1/22
Filed: 1975-02-22
Abstract: The toilet cistern consists of metal, plastics or ceramic. It has internal separate smaller water chamber, to issue only a small amount of water. The small chamber has a separate outlet valve, so that the cistern may be used to flush the toiler in two alternative modes using respectively either a small amount of water or a larger amount as required. Approximate markings indicate which of the amounts of water are released via the respective controls incorporated. Water economy is achieved by the system.

Title: Protective cap for plastic bottles contg. sterilisable solns. - has sealing disc of thermoplastic elastomer at closed end of cylindrical cover
Inventor: MOMMER HEINZ
IPC: A61J1/14
Filed: 1975-03-05
Abstract: Protective cap for the hermetically closed neck of a plastic, e.g. polyethylene or polypropylene, container contg. a sterilisable soln., e.g. an infusion or transfusion soln., has a cylindrical thermoplastic cover with a closed end, and a sealing disc arranged in the cover next to the closed end. The sealing disc consists of a thermoplastic elastomer that softens at the sterilisation tempt., so that the disc becomes moulded over the closed end. The sealing disc fills all of the spaces and surface irregularities between the container neck and cap after sterilisation, thus preventing microbial growth. When a needle is pushed through the cap, the disc material provides an excellent seal, both when the needle is in position, and after its withdrawal.

Title: Desalination of sea water using organic compost - having several adsorption stages wth salts adsorbed onto compost
Inventor: KNEER FRANZ
IPC: C02F1/00
Filed: 1975-07-17
Abstract: Process for multi-stage desalination of sea water involves spraying the water onto the upper surface of a bed of compost. This is obtd. by the biological rotting or composting of organic wastes and/or clarifier sludge. The water is drawn off from the base. Sufficient stages are used to reduce the final salt content to a specified level e.g. to the minimum obtainable by this process. The compost is renewed when it is stad. with NaCl. Pref. the process should have three stages with reducing strengths from each. The adsorbent should be well ripened compost with a water content of >70%. The throughput is controlled by the residual salt content as NaCl, also taking into account the remaining carbonate and sulphate components. Used esp. to provide potable sweet water in areas where only saline water is available. Requires relatively inexpensive installation, has low energy consumption and uses a very cheap adsorbant.
