Title: Imaginary target plane for firing practice - has angle scanners with electronic and optical systems for recording projectiles
Inventor: LIST HELMUT
IPC: F41J5/02
Filed: 1976-09-29
Abstract: The system is used for determining and recording the space coordinates of a free-flying projectile, moving within the field of an imaginary target plane which replaces the conventional solid target. The determination and recording is carried out with an optical and electronic recording system. The target system ensures that on continuous firing, the information about given projectiles is correctly collected. It also ensures that the inclined position of a projectile does not prejudice results. The recording system has opposite angle scanning systems (9). The latter are arranged in the imaginary target planes (16) and outside the firing field (18). This firing field (18) has an illumination unit (10) which is triggered by a projectile (30). Each angle scanner (9) covers the whole firing field (18). It has a rotating mirror and an image-forming optical system between the rotating mirror and a photodiode.

Title: Flow regulating nozzle for water tap - has elastic component to maintain constant flow and reduce noise
Inventor: ZWINK HELMUT
IPC: E03C1/08
Filed: 1976-11-19
Abstract: An approximately constant flow is maintained by an elastic disc (3) with a central hole (4) which rests on top of a rigid disc (5) which has channels (6) running radially from a central recess (10). Increased supply pressure presses the elastic disc (3) into the channels (6) thus restricting the flow. A flow-regulating nozzle (2) is screwed to the pipe (1). The disc (3) is integral with a cylinder (11) of the same elastic material, which fits tightly inside, and forms a seal with the pipe (1). The cylinder has an air-filled annular groove (14) which serves to damp out noise generated by turbulent flow of the water. The regulators operates silently.

Title: Laser light pulse splitter - uses prismatic reflectors set according to time delay required between two components
Inventor: DIELS JEAN-CLAUDE DR
IPC: G02B27/10
Filed: 1977-03-11
Abstract: A pulse splitter separates a laser light pulse into a pair of successive pulses with an adjustable time separation. The incident beam is split at a semi-reflecting surface and transmitted along two different paths according to the time delay required between the two components. The reflecting surface is formed by a pair of prism surfaces so arranged in contact that no total reflection results. The adjustable delay in one path can be produced by a deflection prism which may have a micrometer adjustment. The arrangement permits a more rigid and compact instrument than one using normal semi-reflecting mirrors.

Title: Armour-piercing land mine - which rolls on ground after falling, then rests in correct orientation for max. upward blast
Inventor: PLINGEN KARL-GEORG DIPL ING DR
IPC: F42B23/04
Filed: 1977-09-28
Abstract: Armour-piercing ground mine for land or shallow water use has a cylindrical outer casing which contains a hollow charge with a conical recess or depression at its top, i.e. the final intended orientation of the mine is such that the apex of this depression shall point downwards towards the ground. When dropped from an aircraft or rocket projectile in large numbers the mines roll along the ground, thus scattering and finally coming to rest. To ensure that the mine comes to rest in the desired position, it is equipped with an automatic orienting device. The rolling facility of the mine ensures that a large number when dropped become randomly distributed over the ground. The orienting mechanism ensures that the charge is in the correct upright position when the mine finally comes to rest.

Title: Regulation of gas flow to burner - uses main valve controlled by electric valve controlled by temp. probes
Inventor: BERKHOF HENDRIKUS
IPC: F24D3/08
Filed: 1977-12-14
Abstract: The flow of gas is regulated to control the temperature of hot water heating installation. A single burner is employed to heat different heating circuits to different temperatures. A gas flow regulator (17) comprises a main valve controlled by a pressure regulator via a membrane. This controls gas supplied to a burner (1) through an electric valve. The valve is controlled by a temperature probe (12) in the return flow (7) from a heat exchanger (8). A second probe (13) in the radiator (11) supply operates in series with an ambient temperature thermostat to control selectively the electric valve. A detector (14) reacts to need for heating to control position of a valve (4) in the radiator supply.
