Title: Improvements in or relating to apparatus for treating fibrous materials and products
IPC: B29C59/10
Filed: 1963-07-16
Abstract: 1,057,890. Printing processes. R. LEVAUX. July 16, 1963 [Aug. 16, 1962; April 22, 1963], No. 28172/63. Heading B6C. [Also in Division H1] An apparatus for treating fibrous materials comprises an electric impulse generator having an oscillatory circuit including an inductance coil, and a resonance coil magnetically coupled to said inductance coil, the resonance coil producing a current with a frequency above 100 kc/s., with a high tension above 50,000 volts and a current intensity of about 35 milliamps. The fibrous material may be of natural (e.g. wool), artificial or synthetic origin. The treatment is effected by sparks which modify the molecular and cellular structure of the materials without any appreciable heating. Treated wool may be subjected to a continuous dying process immediately after leaving the apparatus without resorting to any accelerator or protector. Treated materials will not take an electrostatic charge and, in the case of plastics materials, receptivity to adhesive substances (e.g. printing inks) is enhanced. The material 21 is drawn by rollers 22 between an electrode 18 connected to the high-frequency generator and an electrode 19 connected to earth. Electrode 18 comprises a solid or perforated metal plate 18a sandwiched between a glass plate 18b and a mica plate 18c. Electrode 19 comprises a glass plate 19a supported by rods or tubes 19b of copper, silver, bronze or aluminium, which may be curved or straight. The tubes 19b may be replaced by a solid or hollow metal plate covering the whole surface area of the glass plate 19a, or by metal distributed according to a predetermined pattern. Alternatively the glass plate 19a may be replaced by sheaths of dielectric material surrounding the tubes 19b which may be fixed or rotatable.

Abstract: 408,679. Television. MARCONI'S WIRELESS TELEGRAPH CO., Ltd., Marconi House, Strand, DOWSETT, H. M., 47, Drayton Gardens, Winchmore Hill, and WALKER, L. E. Q., 98, Wymering Mansions, Maida Vale, all in London. Oct. 14, 1932, No. 28774. [Classes 40 (iii) and 40 (v).] In a transmitter, in which characters carried by a tape 2 are moved through a scanning-area 1, the portions of the characters, which lie at an approximate right angle to the direction of scanning, are made disproportionately thin. Blurring of these portions, at the receiver, due to images or repetitions of the signals, results in the production of normal characters. The effect is enhanced by causing received impulses above a minimum amplitude to produce markings or indications of fixed density. For this purpose a neon tube is so connected in an inter-valve coupling that received signals above a minimum amplitude cause the tube to break down and apply a predetermined voltage to the grid of the succeeding valve, Fig. 6 (not shown). The blurred portions are thus of standard density. Specification 373,288 is referred to.

Title: Improvements in or relating to the voltage regulation of electric dynamos
IPC: H02J7/22
Filed: 1937-10-23
Abstract: 504,785. Charging and discharging batteries ; automatic regulation. SIMMS MOTOR UNITS, Ltd., KNIGHT, S. C., and PRYKE. D. Oct. 23, 1937, No. 28993. [Class 38 (iv)] A battry-charging dynamo A has a resist ance A<2> in series with its shunt field A<1> and the setting of a vibratory contact voltage regulator B, operating on the resistance A<2>, is altered when the battery reaches a predetermined state of charge so that the charging current is reduced suddenly to a trickle-charge value from a value which is larger than that necessary for the current to fall gradually to a tricklecharge value. The regulator B has a current coil B<2> and a voltage coil B<1> of which the latter is in series with a swamping resistance E. An auxiliary contact D<3> on the cut-out D, D', D<2> controls the circuit of a contactor F<1>, the operating coil F of which is responsive to the voltage of the battery so that'when the battery is fully charged the contactor short-circuits part of the resistance E to lower the setting of the regulator, thereby reducing the charging current suddenly to a trickle-charge value. The contactor F<1> also short-circuits part of a swamping resistance G in series with its own operating coil F to prevent chattering. In a modification all three voltage coils B<1>, D<1>, F are connected in series with a common swamping resistance part of which is short-circuited by the contactor. In a further modification the regulator setting is reduced by the operation of the contactor to alter the effective ampere turns in one or both coils of the regulator. In other modifications the contactor is provided with both shunt and series coils so connected in the circuit that the closing of the contactor is independent of external load on the battery. Reduction of the charging current may also take place in more than one step provided the final reduction is from a value which is higher than that necessary for a gradual reduction to trickle-charge value. Specification 504,561 is referred to. Reference has been directed by the Comptroller to Specification 443,238.
