Title: Machine for grinding hollow workpieces supported on a conveyor - which provides additional support for e.g. tray shaped workpieces
Inventor: HEESEMANN KARL
IPC: B24B7/12

Title: Transposition method for a carrier frequency in a spectrum - has a converter to which the oscillations to be transposed are applied
Inventor: MICHAJLOWSKIJ LEONARD KONSTANT
IPC: H03D9/00
Filed: 1973-12-14
Abstract: The transposed oscillations are collected from the output of the converter which contains at least one S.C. component whose parameters vary with the field strength, polarisation and frequency changes of the field generated by the oscillations to be transposed. An auxiliary modulation of the oscillation to be transposed is provided. Frequency spectrum, polarisation and field strength of the modulated oscillation determine the magnitude and directions of vectors of magnetic and/or electric moments, and of conductance and impedance of the S.C. components in the converter, so that the carrier frequency of each spectrum interval of transposed oscillations is a multiple of the auxiliary modulation frequency.

Title: Toy train and railway station with passengers - arranged so that passengers enter and leave train
IPC: A63H19/00
Filed: 1973-12-18
Abstract: The toy station has two tracks for the train. the passengers are wooden dolls mounted on a base with a spherical undersurface which allows the dolls to slide down a relatively gentle slope whilst maintaining their upright position. The train is held stationary by the lever which also controls the signal and the hinged ramp so that the 'passengers' can slide down the ramp and into the coaches of the train. Raising the lever releases the train, raises the signal arm and tips the ramp so that the 'passengers' are held back. The working of the toy is so simple that it can easily be operated by a young child.

Title: Auxiliary supply circuit for electric train - uses static inverter and thyristor controlled impulse generator
Inventor: HERING FRIEDHELM
IPC: B60L1/04
Filed: 1973-12-20
Abstract: The auxiliary equipment is powered by a special circuit which can draw from a variety of ac and dc traction supplies. When dc is drawn then the system has a thyristor controlled static inverter which powers a control transformer to provide the correct voltages for the dc motor driving the air compressor for the brake system, via rectifier diodes. For AC supplies the transformer operates normally, with the impulse generator part of the thyristor circuit blocked by charging a quenching capacitor via control diodes. The system is simple in layout and enables the train to travel through different supply regions without damaging the auxiliary equipment.

Title: Electronic pulse interval timer - has capacitor charging controlled by resistance fall of working region of transistor
Inventor: SIEFERT ROLAND
IPC: G10H1/26
Filed: 1974-01-08
Abstract: The electronic control circuit is for an electronic signal generator, with a driver component containing a first transistor in whose control circuit is part of an oscillator circuit producing a control potential which can be varied at intervals in the first transistor control circuit, determining the signal sequence of the generator; the variation of the potential is determined by an R.C. circuit. A resistor which determines the charging of the capacitor of the R.C. element is formed by the working region of a further transistor whose resistance gradually varies, after switching on the control circuit, from a high to a low value. Electronic control is obtained of the time intervals between successive signal pulses.

Title: Disintegrating key for safety lock - consists of perforated plates and grid filled with loose components
Inventor: ANASTASSOV IVAN KRESTEV
IPC: E05B35/00
Filed: 1974-02-20
Abstract: It cannot be copied or photographed and it does not leave traces of the key structure. The key can consist of two metal or plastics strips which are, for example, provided with thirty two holes. The strips are connected so that a cavity is formed between these strips. an insert strip is placed between these strips but the diameter of the perforations in this strip is slightly greater than that of the holes in the covering strips.

Title: Rheostat control rod insulated attachment - uses serrated and split ended shaft fitting in plastic boss
Inventor: KLEIN ROBERT
IPC: F16B9/02
Filed: 1974-03-12

Title: Continuously operating gas chromatograph - has adsorption and desorption spaces linked by endless belt drive and ionisation gauge detector
Inventor: BALINT TIBOR
IPC: G01N30/06
Filed: 1974-09-13
Abstract: In one version of the assembly of the continuously operating gas chromatograph, a carrier gas, typically argon, passes through a reducing valve to a monostat and a T-junction, whereat the hydrocarbon gas or similar substance is injected. The next stage is an absorption space maintained at about 20 deg.C, and includes the noble gas discharge outlet. A constant speed worm wheel drive transports the gas by means of a steel or plastics belt to a desorption space, where hydrogen is introduced from a cylinder at a temperature of about 120 deg.C. The emergent hydrogen is fed to an ionisation detector incorporating a dry-battery, d.c. amplifier and a recording instrument. The transporter belt returns to the absorption space through a narrow curvilinear channel.

Title: Pretreating mouldings for electrostatic coating - by mixing conducting material with mould lubricant
Inventor: GEVATTER PETER
IPC: B29C33/60
Filed: 1974-10-15
Abstract: Plastic mouldings are pretreated for electrostatic coating, using a conducting surface, by first spray-coating the mould with a mixture of release agent/conducting coating which blends into the surface of the moulding produced, this being extracted after cooling. Conducting coating is applied uniformly without separate treatment. The release agent has to be used in any case and bonds to the surface of the moulding during curing, thus ensuring everywhere a good bond also to the conducting coating. A suitable release agent is a metallic soap plus ethyl cellulose and solvent. The conducting material mixed in is e.g. tertiary amines in low boiling point solvent. The mix is sprayed on the mould wall to a coating of 0.005 mm.

Title: Mechanism for releasing non-ferrous ingots from their moulds - as part of a continuous conveyor-belted process
Inventor: KIKKAWA TAKAHIRO
IPC: B22D5/04
Filed: 1974-10-09
Abstract: The conveyor belt carries the moulds, two abreast, open-side upwards along the upper part of its length, then moves them round a vertical semi-circle so that they return, open-side down, along the lower part of the belt.
