Title: Apparatus for the production of quantities of gas having an excess of positive or negative ions
IPC: H01T23/00
Filed: 1926-12-14
Abstract: 262,829. Dessauer, F., and Universitats Institut fur Physikalische Grundlagen der Medizin. Dec. 14, 1925, [Convention date]. Electric and magnetic appliances.- In order to influence animal life and biological reactions, an excess of positive or negative ions is imparted to a current of gas by first ionizing it, without the passage of an electric discharge, and then passing it through electric fields which retain as completely as possible the ions of underised polarity while allowing to pass, or accelerating, those of the desired polarity. The ionizing means 6 may be a source of R÷ntgen or ultra-violet rays, an incandescent platinumiridium sheet with or without a coating of alkaline earth, a Nernst rod, or one or more tungsten filaments, which may be thoriated. After passing through or around the ionizer 6, the gas traverses grids 7, 8, which may have a mesh of 2 mm. diameter. In order to obtain positively-charged gas, the first screen 7 may have a negative potential of 7 kilovolts and the second screen 8 and ionizer may be at zero potential. The dimensions of the apparatus, the electric fields, and the velocity of the gas must be proportioned in order to obtain the best results, and for this purpose the current of gas, the ionizer, and the electric fields and adjustable either independently or simultaneously. For negatively charging the gas, the grids 7 and .8 may have positive potentials of 4.5 and 9 kilovolts respectively. The field between the ionizer and first grid may be so high that further ions are produced by impact. Before treatment the gas may be passed through a cleaner 2 and meter 3. According to the Specification as open to inspection under Sect. 91 (3) (a), ionization may be produced by a high-frequency or continuous high-voltage discharge, which may be silent and invisible; also the cathode may be situated between the grids, and the controlling grid may be of plate form. This subject-matter does not form a part of the invention described in the Specification as accepted.

Title: Improvements in or relating to the surface treatment of polyethylene-containing strucures
IPC: C08J7/14
Filed: 1953-11-24
Abstract: The surface of a polythene film, tube or other structure is treated at 25 DEG  to 95 DEG  C., continuously with the extrusion of the product at a temperature between 150 DEG  C. and the degradation temperature of the polythene into a quench bath, with an aqueous solution of a halogen, a hydrogen halide, hydrogen peroxide, nitrous acid or an alkaline hypochlorite, or with concentrated nitric acid or a mixture of concentrated nitric and sulphuric acids.  The reagent may be employed in aqueous solution in the quench bath which may be agitated or subjected to sonic or supersonic vibrations or to ultra-violet light.  The treatment is followed by neutralization in an aqueous solution of sodium hydroxide, or a mixture of sodium bicarbonate and hydrogen peroxide, and thereafter washing with water. The treatment improves the receptivity of the products for printing inks and coatings of cellulose derivatives or synthetic resins, and improves their adhesion properties in the production of polythene laminates or laminates of polythene with metals or paper, in which standard adhesives may be employed.  The process may be extended to the treatment of products of copolymers of ethylene with isobutylene, vinyl acetate, styrene or vinyl chloride.  A mixture of the reagents which does not impair the efficacy of the process may be employed. The process of extrusion includes the formation of films in heated calender rollers. Specifications 557,544 and 738,474 and U.S.A. Specification 2,430,860 are referred to.

Abstract: 645,337. Frequency changing. TUCKER, D. G. Nov. 1, 1946, Nos. 32562 and 35101. [Class 38 (ii)] [Also in Groups XXXVI and XL (c)] In a circuit for pro. ducing an output propor tional to the square of the input for use in a fre quency doubling circuit e voltage derived from the current due to the applied voltage through a rectifier or other non-linear resistance having a parabolic form over at least part of its characteristic is combined in opposite sense with a voltage proportional to the input voltage such that the resulting characteristic has pure square law form. As shown, a rectifier R having such a characteristic (i.e. I=av+bv<SP>2</SP>) and a small resistor r are connected in series across the input terminals 10 and in parallel with a potentiometer R1, R2 which is adjusted to produce a voltage equal and opposite to the voltage across resistor r due to the term AV of the rectifier characteristic and the output at the terminals 11 is therefore proportional to the square of the input. The required characteristic is more accurately obtained when the input voltage is small and thus the steady component of the rectifier resistance negligible. In an alternative circuit (Fig. 2, not shown), a diode valve in series with a resistance-capacitance self-biassing circuit replaces the rectifier R, a baretter being is provided to stabilize the diode heater current.
