Patent DE-2729350-A1 (DE)
Title: Splicing method for cine film - uses diagonal splice to enable sound synchronisation to be preserved over 18 frame displacement
Inventor: SCHELLER THOMAS
IPC: G03D15/04
Filed: 1977-06-29
Abstract: Splicing method is for cine film where the displacement between picture and sound is 18 frames. The film is cut diagonally (S) so that there is a gradual fade between the picture of the two sections (A1 to A18 and B1 to B18) and the sound remains in sync. The diagonal cut allows the sound track to 'reach forward' to the sound head of the projector so that the portion of the sound track (T1) associated with the first full frame (B19) of the spliced section are amplified and projected together. The diagonal splice is joined by tape.

Title: Stabilised suspension for beam axle - has offset mountings for dampers to provide symmetrical displacement
Inventor: CLAASEN GUENTER
IPC: B60G9/00
Filed: 1977-10-29
Abstract: The dampers (9, 10) for the beam axle are linked to the axle by extension arms (11, 12) to provide an offset mounting. This ensures that the damping effect is the same for symmetrical and off set displacement of the wheels. The improved mounting has no additional moving parts and is simple set up. It provides a more comfortable ride and improved cornering stability.

Title: Rotating die machine for forging round bars - has motor brake and free wheel drive to increase operating speed
IPC: B21J7/16
Filed: 1978-04-27
Abstract: A machine for forging round bars has a driving shaft which carries two radially oscillating rams with semi-cylindrical dies. The rams are pushed inwards as the rounded head of the ram passes over one of the surrounding rollers. After passing the roller the rams move outwards under centrifugal force, and release the bar passing through the dies, so that it can be moved forwards. To reduce operating time, the motor driving the shaft is braked at the instant the dies come together whilst a free wheel allows the shaft to continue to rotate until the bar is released.

Title: Make-and-break spark plug - has induction coil whose field rotates middle electrode about long axis to break short circuit between middle and earthing electrodes
Inventor: LACK RENE
IPC: H01T13/42
Filed: 1978-04-29
Abstract: The make-and-break spark plug finds application in burners, combustion engines, jet engines etc. for their ability to generate sufficient sparks at low voltage. It has an induction coil whose magnetic field rotates a middle electrode (14) about the longitudinal axis of the spark plug against a spring force. Thus a short circuit path between this electrode and an earthing electrode is broken and a spark is generated. The middle electrode is axially mounted. Preferably this electrode and/or a retaining armature (17) are mounted in an axial bearing (23) which may be in the form of a roller bearing. Alternately a slide bearing may be used. The middle electrode may be fitted with a labyrinth seal (16).

In the kneading trough, an acid culture is added in an amount which is greater than that of the sweet buttermilk bringing the separate particles of butter from the screen into the trough. Used to convert butter particles from sweet cream by a simple acid culture into sour cream butter and to remedy the failings of existing methods which are not only expensive in themselves but also yield a product lacking in taste and aroma. Provides a continuous prodn. process ensuring the maximal permissible water content and content of matter contg.

Title: Cavity wall suspended from reinforced concrete ceiling - has panels hung on head batten fixed to formwork, leaving gap for sag
Inventor: SIMONS FRANZ DR ING
IPC: E04B2/82
Filed: 1978-05-26
Abstract: The double-skinned external or internal wall is hung onto the retained formwork of a ceiling made of reinforced concrete. A head batten (3) is fixed to the formwork (6) which is firmly connected to the ceiling. Panel elements (7) of the wall, incorporating groove and tongue, are hung onto the batten sideways. A movement joint gap at the bottom permits vertical displacement of the wall as a result of ceiling sag. An elastic intermediate layer may be inserted between batten and panels, stressing the fixture elements so as to preserve a prescribed vertical gap (12) between adjacent hung panels. This provides for sag in a wide-span ceiling, without transferring.

Title: Starting arrangement for small synchronous motor - uses temporarily connected commutator and slip-rings in winding circuit
Inventor: MERKLE PAUL
IPC: H02P1/46
Filed: 1978-06-27
Abstract: A circuit is designed for starting of small synchronous motors having a toothed iron rotor and two toothed but circumferentially displaced stators with an excitation coil. Stator and rotor cores are typically of single thin steel plate construction. To ensure starting in the correct direction each stator coil is temporarily connected via contacts on a commutator and slipring mounted on the shaft. A switch for this purpose also operates the brushes to prevent unnecessary wear. Once the motor runs the switch can be released and normal running is instituted.

Title: Demodulator with two mixers - has phase shifter in one signal path and in one reference signal feed to eliminate unwanted frequencies
Inventor: BAUR KARL PROF DR
IPC: H03D1/24
Filed: 1978-06-28
Abstract: The demodulating circuit passes the input signal through two paths (S1, S2) whose outputs are combined by an adder. Phase shifters are incorporated in the signal paths to introduce a phase of 90 deg. between the two paths. A 90 deg. phase shift is given to the reference signal fed to one of two mixers. The sign of the phase shifts are chosen so that sum and difference frequencies not belonging to the wanted baseband frequency (f) cancel one another in the adder (ZSF). The frequency of the first oscillator's output has the same positional relationship w.r.t. the wanted band of the input signals as zero frequency has w.r.t. the baseband.

Title: Use of 2-cyano-aziridine(s) to treat damage due to radiation - reduces the leukopenia resulting from damaged bone marrow
IPC: A61K31/675
Filed: 1978-10-28
Abstract: The use of 2-cyanoaziridines (I) to avoid or reduce damage due to radiation is novel. An esp. pref (I) is 2- 2-cyanaziridin-1-yl- -2- 2carbamoylaziridin-1-yl -propane(Ia). Suitable doses are 5-500 mg/kg body wt. applied either as a single dose or several unit doses. As the effect drops slowly after approx 2 weeks, it can be necessary to repeat treatment with (I). (I) can be applied at the same time as or after radiation treatment to compensate for the damage to the bone marrow the radiation would normally cause. This damage to the bone marrow can be observed in the leucopaenia in peripheral blood ie in the reduction in the level of white blood corpuscles.
