Title: Improvements in or relating to stabilized amylose solutions and the use thereof
IPC: C09J103/12
Filed: 1963-04-25
Abstract: An amylose aqueous dispersion of pH at least 9.5 contains (a) paraformaldehyde or an operable equivalent consisting of glyoxal, an aqueous solution of formaldehyde or methanolstabilized formaldehyde, or a non-polymerized urea-formaldehyde concentrate, and (b) urea or an operable equivalent consisting of succinamide, adipamide, or a basic nitrogen-containing compound which forms an N-methylol derivative with formaldehyde.  The amylose may be pure amylose separated from a starch or may be a high-amylose starch containing at least 55% of amylose.  Addition of the ureaparaformaldehyde system to the amylose dispersion stabilizes it against precipitation, and allows it to be used in adhesive formulations. The dispersion may also contain, as partial replacements of the urea, paraformaldehyde or operable equivalents, glyoxal, acetaldehyde, furfural, benzaldehyde, thiourea, a cyclic urea compound, a trimethylol alkyl or aryl compound, dicyandiamide, melamine, hydrazine hydrate, morpholine, ethylene glycol, a watersoluble alcohol, a ketone or a primary or secondary amine.  The proportions of paraformaldehyde and urea (or operable equivalents) may be as much as 200 parts per 100 parts of amylose.  Stabilizing salts may be added e.g. ammonium salts or chlorides, nitrates and acetates of alkali or alkaline earth metals.  The alkaline pH of the dispersion may be maintained by addition of e.g. sodium and potassium hydroxides, or sodium carbonate silicate or phosphate.  Formulation of an adhesive composition may be completed by adding to the stabilized amylose dispersion a filler e.g. clay, resins, and raw starch.  In an example, a slurry of amylose, water and paraformaldehyde is heated to 330 DEG  F. under pressure, cooled to 160 DEG  F., and mixed at 160 DEG  F. with urea and an alkali.

Title: Improvements in electron discharge devices
IPC: H01J19/68
Filed: 1929-05-30
Abstract: 312,922. British Thomson-Houston Co., Ltd., (Assignees of Kingdon, K. H.). June 1, 1928, [Convention date]. Vacuum tubes; lowpressure metallic-vapour apparatus.-In a discharge device having an electron emitting cathode sensitive to bombardment by ions and operated in an activating vapour or gas at low pressure, a conducting shield, mechanically separate from and surrounding the electrodes, is maintained at or near the potential of the cathode so as to collect ions and shield the cathode from bombardment. In the arrangement shown in Fig. 1, the shield consists of a metal cylinder 10 surrounding a filament cathode 2, a grid 5, and an anode 3. The grid consists of two wires connected at the top and mounted between the cathode and two plates forming the anode so that the three electrodes are in the same plane. A bent support 8 carries the shield 10, the upper end of the filament, and a glass bead 9 supporting the upper ends of the anode and grid. Transverse wires 13, 14 are mounted so as to bear lightly against the filament and reduce vibration. The filament may be treated in an atmosphere of oxygen after the preliminary evacuation and before sealing, and a deposit of caesium or other alkali metal is formed on the treated surface by distilling the metal from a mixture of caesium dichromate and a reducing agent, such as powdered silicon, contained in two capsules 16 secured to a plate which is heated by induced current. The shield is maintained at the potential of the cathode. In a modification, the anode plates are arranged in planes at right angles to that of the filament and grid, and are surrounded by closely-wound helical screening grids which extend beyond the anode and have supporting rods mounted on a horizontal anti-capacity screening plate. Specifications 224,544 and 256,279 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the arrangement shown in Fig. 10 (Cancelled), in which the collecting shield is combined with the grid and consists of radial plates 62 secured to a spider 58 having four lugs 59 for the reception of grid wires 57, which are welded to the lugs on the lower spider and slide freely in those in the upper spider. The anode consists of a cylinder with radial vanes 50. In this arrangement ions are produced in the space between the anode and the grid are attracted to the plates 62. This subject-matter does not appear in the Specification as accepted.

Filed: 1946-06-01
Abstract: 629,892. Valve closure members. SIEURIN, S. A. June 1, 1946, No. 16714. [Class 135] A through - way valve comprises a casing 1 with a cylindrical bore for an expansible plug comprising two semi-cylindrical members 18, 19 yieldingly forced against each other by a spring or springs, elastic split rings or like spring means and positively forced apart into contact with the cylindrical bore by two cone members 13, 14. One of the latter, 14 is carried on a removable threaded plug 3 and the other 13 is carried on a threaded part of the operating stem 7. The stem 7 carries a hand wheel 9 and a pointer 20 and rotates in a packing gland 10 11. The cone member 13 has lugs 15 engaging radial slots 16 in the upper surface of the plug such slots being formed partly in each semi-cylindrical member. Arcuate springs 17 embrace lugs formed on each side of the slots. The cone 13 and therefore the plug members are prevented from clockwise rotation by spring-pressed pawls 6 engaging an annular set of radial teeth 5 formed on a member 4 screwed inside the casing. In opening or closing the valve, a counterclockwise rotation of 90 degrees causes the cone 13 to ride up the stem until stopped by a collar 8. Thereafter a further counterclockwise rotation of 90 degrees opens or closes the valve. The stem 7 is then rotated clockwise for 90 degrees and since the cone 13 and the plug members are prevented from clockwise rotation by the pawls 6, the cone 13 rides down the operating stem and expands the plug into sealing contact with the cylindrical bore.

Abstract: 869,577. Valve amplifier circuits. TESLA, NARODNI PODNIK. May 27, 1958 [May 25, 1957], No. 16854/58. Class 40(6). The invention relates to low frequency amplifiers of the type in which the input signal is in the form of width modulated pulses applied to a valve to render it fully conducting or non-conducting, the valve being connected to an inductive load and to any energy recovery diode so as to produce in an output circuit a mean current representing the modulation of the input wave. In the Figure the modulated input pulses are applied to the grid of a valve 1 which is connected to the HT supply through a pulse repetition frequency choke 4<SP>1</SP> and a low frequency choke 7<SP>1</SP>. There is also provided a diode 2 which is connected through a further pulse frequency choke 4 to the load 8 and to a low frequency choke 7 connected to earth, the anodes of the valves being connected together through a capacitor 3 having a low impedance at the pulse frequency. A capacitor 5 having a larger value than capacitor 3 is connected between the outer ends of the chokes 4, 4<SP>1</SP>, while a pulse frequency filter capacitor 6 connects the right-hand end of pulse choke 4<SP>1</SP> to earth. Fig. 2 shows the grid input voltage U g1  under various modulation conditions, the corresponding anode voltages U a1  of valve 1 and the anode currents I a1 , I a2  of valves 1 and 2. It will be seen that the mean anode current for unity mark space ratio of the input signal is nearly zero but varies from this value in accordance with the modulation. Chokes 7 and 7<SP>1</SP> may be two windings of a transformer in which case capacitor 5 may be replaced by a capacitor between the right-hand side of pulse choke 4 and earth.
