Title: Improvements in or relating to methods of manufacturing indirectly heated cathodes
IPC: H01J1/24
Filed: 1956-02-06
Abstract: 785,177. Electrically heated cathodes of discharge tubes. PHILIPS ELECTRICAL INDUSTRIES. Ltd. Feb. 6, 1956 [Feb. 9, 1955], No. 3627/56. Class 39(3) [Also in Group XL(a)] In making an indirectly heated cathode for an electric discharge tube in which the space between the heater filament 3 and the cathode sleeve 2 is filled with sintered insulating material, the latter is introduced into said space by sedimentation from a suspenson, and the distance the particles have to travel is at least twice the length of the space to be filled. Thus 1 kg. of aluminium oxide ground to particles varying from 1 to 15 microns in size is suspended in one litre of ethyl alcohol and poured into a metal holder 5 having a cavity 9 with walls tapering to a lower cavity in which the cathode sleeve 2 fits. The cathode may be tubular, or, as shown may be a dispenser cathode with an emissive part 1 and a depression 4 in the periphery of the sleeve 2. Two holders 5, 8 each with a cathode assembly may be mounted in cavities 7 in a second holder 6 of synthetic resin, each cavity 7 having at its base a narrowed portion 8 to receive the depression 4 and emissive part 1. When the holders 5 are filled with the suspension the larger particles settle first and the size of the particles decreases upwardly. The sleeve 2 is filled nearly to the top. The liquid is then decanted or evaporated, and the holder heated until the aluminium oxide particles are sintered, e.g. by heating for two hours at 1000C and then for 15 minutes at 1600C. The sedimentation may be accelerated with the aid of a centrifuge, the holder 6 being suspended from an annular member 11 supported from arms 10 of a centrifuge revolving on a vertical axis.

Title: Improvements in or relating to moisture meters
Inventor: SHUFFLEBOTHAM KENNETH
IPC: G01N27/04
Filed: 1960-02-02
Abstract: 885,306. Determining moisture content. MARCONI INSTRUMENTS Ltd. Sept. 23, 1960 [Feb. 2, 1960], No. 3660/60. Class 37. An electrical conductance moisture meter comprises a grinder adapted and arranged to grind material placed in the apparatus, a handle adapted to actuate the grinder, a cell containing electrodes and positioned to receive ground material as it passes out of the grinder, and means, operable by the handle when it has been moved to a predetermined position, for compressing the ground material in the cell to a desired predetermined extent. The apparatus comprises a body or barrel 1, into which are fitted a conductance measuring cell 2, female grinder 3 and housing 4; the latter, which is secured to the barrel 1, being internally screwthreaded and carrying a hollow-threaded screw 17 provided with a counter bore 18 at its lower end and two keyways 19 over the remainder of its length. In operation the top cap 5 is removed and barrel 1 is loaded to a predetermined height with the material, e.g. grain, whose moisture content is to be measured and the cap 5 replaced so that L-shaped locating pins 24 which engage the flattened sides of a spindle 21 carrying a male grinder 22 pass through and beyond the keyways 19 into the counterbore 18, in which position two spring- loaded balls 26 engage the upper groove 25 in the cap 5. When the top cap 5 is now rotated the screw 17 remains stationary due to pressure exerted thereon by spring-loaded ball 27 whilst the spindle 21 and male grinder 22 rotate; the ground material falling into the measuring cell 2. On completion of grinding the top cap is rotated with an upward pressure until the lower ends of the locating pins 24 engage in keyways 19 and the balls 26 engage the lower groove 25 in the top cap. The top cap 5 is again rotated with sufficient force to overcome the resistance of the ball unit 27 and, due to the engagement of the locating pins with the keyways 19, screw 17 also turns causing it to be driven down and causing pressure pad 23 to compress the ground material in the measuring cell and force contact pins 12, 13 of electrodes 10, 11 out from the bottom of the apparatus to permit a measurement to be made between them; this motion being limited by abutment members 15, 16. The two contact pins may be replaced by a single central pin connected to electrode 10; electrode 11 being earthed to the metal body of the grinder unit via housing 7.

Title: Improvements in the treatment of linear super polyamides preparatory to dyeing
IPC: D06M11/11
Filed: 1943-03-08
Abstract: Textile materials containing synthetic linear polyamide filaments or fibres are treated with an aqueous solution of a strong acid at a concentration high enough and for a sufficient time to produce an improvement in their dyeing affinities without substantial delustring.  The aqueous solution is selected from the group consisting of sulphuric acid of 42-47 DEG  Twaddell, hydrochloric acid of 14-16 DEG  Tw., nitric acid of 25.5-30 DEG  Tw., orthophosphoric acid of 10-12 volumes of acid of 1.75 specific gravity to 12 volumes of water, and formic acid of at least 65 volumes of acid of 1.2 specific gravity to 35 volumes of water, but less strong than 80 volumes of acid of 1.2 sp. gr. to 20 volumes of water.  The treatment may be applied uniformly over a fabric or yarn or may be applied over local areas.  Mixed fabrics, yarns, or fibres may be treated.  The materials may be passed through the solution of acid, then through a mangle, through washing and neutralizing baths, and then to a drying device.  The acid treatment may be effected at ordinary temperature.  The polyamide yarns or fabrics may be dyed with Chlorazol Sky Blue FFS or Green G, Victoria Pure Blue BOS, Safranine TS, or Caledon Brilliant Purple 4S.  The Provisional Specification describes also the treatment of synthetic linear polyamide materials with more concentrated acid solutions or with acid solutions at elevated temperatures, so as to produce delustring. Formaldehyde may be included in the acid.  Antimony trichloride may be included in a solution of hydrochloric acid so as to obtain a weighting as well as delustring of the nylon materials.
