Patent DE-2413318-A1 (DE)
Title: Marking drop-outs in flexible magnetic tapes - by recording electronic marks in separate track as drop-outs are registered
Inventor: DRESCHER TORSTEN DIPL PHYS
IPC: G11B27/36
Filed: 1974-03-20
Abstract: In magnetic tape manufacture, so-called "drop-outs" may occur owing to dust or fibre on the surface or insufficient coating. These cause interference, e.g. horizontal lines on screens in the case of video tapes. The present arrangement makes marks electronically on a separate track of the tape by means of an audio head at the same time as the drop-out is registered by scanning the tape with a rotating head. The mark is made at a given distance from the drop-out and is subsequently located by a rotating magnetic head so that the drop-out can be evaluated by means of a microscope or magnifier.

Title: Automatic accident warning transmitter - uses hand wound sprint to broadcast distress signal when vertical post is dislodged
Inventor: WILLIS JOHN GEORGE
IPC: G08B21/18
Filed: 1974-04-11
Abstract: An automatic accident warning system which requires no powr supply, but which broadcasts a distress message via a small transmitter when an accident occurs, is described. The device is suitable for application on roads or in remote buildings. The warning is broadcast by means of a transmitter and aerial mounted on a vertical post or column, and disturbance of which is used to indicate that an accident has occurred. The electric power is produced by a generator which is driven by a steel clock type spring via a gearbox. The opening can be wound up by hand via a suitably inserted key. The spring remains wound until released either by a hand operated lever or by the movement of a pendulum attached to the spring release linkage.

Title: Fuel-air mixer with fuel injector - providing complete mixing in mixing pipe uses fuel sprayed in under pressure
Inventor: HEROLD WILHELM
IPC: F23D11/34
Filed: 1974-04-22
Abstract: Fuel-air mixer comprises a mixing pipe including one or more nozzles of fuel injector connected to a fuel pump. Each nozzle is directed onto one or more baffle surfaces in the mixing pipe, either perpendicularly or at an angle of 0-90 deg, or in a direction perpendicular to or parallel to the main flow direction in the mixing pipe. The nozzles are opened and closed by a pulse generator with independently variable opening and closing times, which is controlled by the throttle valve in the mixing pipe. The baffle surfaces are vibrated by a piezoelectric generator to assist in atomisation of the fuel.

Title: Lacquering carbon and low alloy-steel wires and strips - with pre-treatment by blasting with steel balls
Inventor: HELLING WERNER DR ING
IPC: B05D3/10
Filed: 1974-06-28
Abstract: Carbon steel and low alloy steel is treated, prior to lacquering, by etching the surface by blasting it with steel balls, partic. for parts requiring a high resistance to cracking, e.g. springs. The surface is then wet-polished in several stages, pref. by passing the article through a tank contg. the polishing fluid in the form of a suspension, an emulsion, or a combination of solid bodies and a soln. which attacks the material to a low degree. The surface is then phosphated, and coated with pigmented lacquer. The wet polishing provides a high degree of smoothness which improves appearance.

Title: Digital telephone system stores transmitted communications signals - and only passes them to coupling matrix when given number are present
Inventor: WINTZER KLAUS
IPC: H04Q11/04
Filed: 1974-09-30
Abstract: The digital telephone system has the communications signal from any one transmitter stored before being released to the connecting matrix. Only when a given number of communications signals are present are they released to the connecting matrix together with the address signal of their destination receiver. The address signal controls the connection processes in the matrix. The advantage of the system lies in its allowing in a relatively simple way transmitted communications signals and their destination address signals to be transferred via a connecting matrix. The system also allows the number of signals at the connecting matrix to be increased.

Title: Frequency converter which produces IF from carrier - operates by mixing using sample and hold circuit triggered by pulse generator
Inventor: SCHECK WERNER DIPL PHYS
IPC: G01R13/34
Filed: 1975-08-07
Abstract: The frequency converter produces eg an IF signal from a carrier wave by mixing with the harmonic outputs of a local oscillator. The converter contains a sample and hold circuit which is triggered from a pulse generator to convert the frequency of a periodic signal depending on its overtone spectrum. When a triggering pulse appears, the voltage of a capacitor is compared with an external voltage. Periodic delta pulses are used for mixing with periodic pulses for frequency conversion.

Title: Contact element with serrated prongs for flat cables - forms solder free joint with lead by cutting through insulation material and bending lead
Inventor: AUMANN VITAL L DIPL ING
IPC: H01R4/24
Filed: 1975-09-22
Abstract: The contact element has prongs used as connecting terminals for flat cables. Each connected lead forms a solder free connection with the contact element by being clamped between the prongs. The prongs (4, 5, 6) on the conductor side are made with sharp serrated edges (7). The leads (8) will produce cold deformation of the prongs when clamped between them. The prongs are very stiff and the force required produces a pressure on the leads exceeding the limit of elasticity of the material from which the leads are made. The insulation of the leads will be penetrated so that contact is made to the oxide free material of the lead.

Title: Physical quantities transmission method - uses light source whose light is applied through light conductor to HV point of measurement
Inventor: UMMEN FRANZ
IPC: G01R15/24
Filed: 1975-11-05
Abstract: A measurement pickup tickets the light to butt ends of further light conductors of a light conducting cable, which applies it to a phot-receiver for evaluation. The light emitting conductor is wound in a spiral free from stresses in its rest position. It is moved by the torque of a pickup, as a function of the measured current, over a measurement sector so that a number of further light conductors terminated by photocells, conduct back the light falling on them. This light is converted into electric signals used for measurement.
Patent DE-2550221-A1 (DE)
Title: Electrical machine with moving and fixed permanent magnets - has coils for instantaneous reversal of selected magnets
IPC: H02K41/02
Filed: 1975-11-08
Abstract: The motor comprises a rotating permanent magnet (16) and stationary permanent magnets (13), the latter being also equipped with windings (14). Motion is induced by changing the polarity of the stationary pole when the unlike pole of the rotating magnet is opposite. A linear motion motor can also be constructed using the same principle. As the polarity and flux to a permanent magnet can be established by applying the necessary magnetomotive force for only a very short time the reversal of a magnet can take place with very little energy input. The machine utilises very short duration high mmf impulses to achieve the reversing effect and thus produce the motion.
