Patent DE-2807764-A1 (DE)
Title: Rotationally stabilised projectile with homing system - has inertia system automatically aligned on firing by detaching out-of-balance mass
Inventor: SCHULTZ PETER PROF DR ING
IPC: F41G7/00
Filed: 1978-02-23
Abstract: The rotationally stabilised projectiles has a system for guiding the projectile at least at the final stage of flight. The inertia mass used within the projectile is initially aligned by a simple method independently of the gun setting. The inertia mass ring (5) has a detachable rotor mass (11) causing out of balance forces. This detachable mass is separated from inertia mass due to acceleration of the projectile on firing. A rotation damping arrangement is provided between the inertia mass and the projectile. This damping arrangement is rendered inoperative when the out of balance mass is separated.

Title: Blocking circuit for code converter in TDM transmission system - has thyristor operated by switch and controlling relays excitation current
Inventor: AMBRUNN EWALD ING GRAD
IPC: H04Q11/04
Filed: 1978-04-07
Abstract: The blocking circuit is triggered by operating a switch and disables the excitation circuit of a relay to regulate its excitation current. A thyristor (Th) is located by its anode /caathode path in the excitation circuit and has its anode biased positively with respect to its cathode. The thyristor anode/cathode path is in parallel with the gate/anode path of the switch (S). When the switch is open the thyristor only turns off if the excitation current exceeds a given value. The code converter control circuitry is designed so that this cannot happen which means that the thyristor/control circuit combination is a very simple way of providing a blocking circuit.

Title: Transmission system for remote-control signal-packets - reduces cycle times by having substations distribute transmissions over several interrogations
Inventor: BIZER WERNER DIPL ING
IPC: H04Q9/00
Filed: 1978-10-12
Abstract: The transmission system has all substations interrogated by a central station simultaneously during breaks between current measurement data interrogation to see whether they are ready to send spontaneous information. Only those substations with spontaneous information notify the central station that they want to send via a shared monitoring channel. The central station then interrogates these substations sequentially. The substations with spontaneous data to send notify the central station immediately after interrogation. When spontaneous data is present simultaneously at different substations distribute their spontaneous data arbitrarily amongst several interrogations.

Title: Pressurised adhesive application system - uses pressurised air jet, to atomise adhesive when emerging from nozzle
Inventor: HARTMANN FRANZ
IPC: B05B7/06
Filed: 1979-06-15
Abstract: The process is for the application of pressurised adhesive from a nozzle onto a substrate. The adhesive is atomised when emerging from the nozzle. The atomisation is achieved by a pressurised air jet, directed at an acute angle against the adhesive jet on all sides, to divide it into thin threads, which form a thin net-like adhesive film on the substrate. The nozzle has a lower outlet aperture (6), surrounded by a concentric gap (8), the direction of jet from the gap being inclined to the axis of the outlet. The gap is supplied via a compressed air channel.

Title: Vehicle antiskid brake control - has electronic control to balance modulation on cornering
Inventor: KLAUE HERMANN DR ING
IPC: B60T8/44
Filed: 1979-06-29
Abstract: An anti skid brake control provides a modulated brake pressure to either of the front wheels if the control senses the onset of wheel lock, while the rear brake pressure is modulated w.r.t. the dynamic situation of the vehicle. For straight travel the rear wheel brakes are unaffected while on cornering they are vented to prevent slewing. The control provides maximum braking effort in different dynamic situations. It enables braking control to be safe even on cornering and releases the rear brake pressure if braking causes slewing.
