Filed: 1970-06-16
Abstract: 1275226 Electron guns RCA CORPORATION 16 June 1970 [16 June 1969] 29134/70 Heading H1D A method of construction of an electron gun in the manufacture of a cathode-ray tube, e.g. a colour T.V. tube, comprises the steps of fixing the position of a control grid in the tube; movably mounting the cathode in alignment with the grid; evacuating the tube and applying operating voltages to the electrodes with a desired beam cut-off voltage between the cathode and grid; then adjusting the cathodegrid separation until beam cut-off is achieved when the cathode position is fixed. The screen grid 13 and control grid 15 are supported on insulating rods 17 which also support a flange 18 of a metal cathode support sleeve 19 within which a cathode cylinder 21 is slidably mounted. The upper end 22 of the cathode is closed and has an electron emissive coating 23 and the lower end is attached by welding to an expansion bellows 25 of nichrome or other material of high thermal expansion. The lower end of the bellows is supported by the insulating rods 17 so that heating of the bellows, e.g. by a pulsed ruby laser 37 reduces the cathode-grid separation. The cathode-grid separation is initially adjusted to be larger than the critical separation for beam cut-off and the bellows is heated until the cathode-grid separation is such that beam cut-off occurs when the cathode is spot welded to the support sleeve 19 by heating means, e.g. a ruby laser 45. In further embodiments, the cylindrical cathode abuts against a bowed strip of high thermal expansion or against a bimetallic strip in place of the expansion bellows.

Title: Improvements in or relating to machines for sorting perforated statistical record-cards
Filed: 1925-11-19
Abstract: 243,364. British Tabulating Machine Co., Ltd., (Assignees of Bryce, J. W.). Nov. 20, 1924, [Convention date]. Compiling statistics.-In a sorting machine for Hollerith cards read in motion there is a sorting brush at each station or deflector, the stations being one card cycle apart. The cards are fed with the " 9s " first under each brush; the main brush circuits are momentarily made live by the usual cam contacts 119 when the cards are simultaneously in their correct reading positions and in these positions at the first station the brush rests upon the " 9 " perforation index point, at' the second station upon the " 8 " point, at the third station at the " 7 " point and so on. Thus a card will only permit contact through its perforation while the main brush circuit is live when the card is at the correct sorting station. This energizes a magnet 107 which attracts its armature 111 and raises the deflector 108. At the same time the armature closes contacts 113 to complete a holding circuit 121 which is broken at' the correct moment by cam 120. The brushes are individually adjusted transversely of the machine to any card column. The construction of the sorting boxes, card-feed conveyer rollers and card-feed picker-blade mechanism are as described in Specification 242,654.

Abstract: An aqueous composition for proofing textiles, wood and similar materials comprises a water-soluble salt of an aromatic hydroxy compound possessing anti-mildew properties and a water-soluble bactericidal quaternary ammonium compound, both maintained in solution by means of a surface-active agent which is a condensation product of an alkylene oxide with an organic compound containing a hydrocarbon group and an active hydrogen atom or an alkali metal or ammonium salt of a condensation product of formaldehyde and an aromatic sulphonic acid.  Specified aromatic hydroxy compounds include salicylanilide, trichlorophenol, pentachlorophenol, 2, 21-dihydroxy-3, 5,31, 51-tetrachlorodiphenyl methane and 2,21-dihydroxy-3,5,6,31,51, 61-hexachlorodiphenyl-methane, used as their ammonium or alkali metal salts.  Specified quaternary ammonium compounds include cetyl trimethyl ammonium bromide and cetyl pyridinium bromide : the chlorides and methosulphates may also be used.  The alkylene oxide condensation product may be formed by reacting an alkylene oxide such as ethylene or propylene oxide with fatty alcohols or acids, wool grease alcohols or acids, polyhydroxy compounds partially esterified with fatty acids, long chain alkyl phenols, or long chain amino, amido or mercapto compounds.  The second group of surface-active agents may be obtained by condensing an aromatic sulphonic acid with formaldehyde or by sulphonating a formaldehyde-aromatic compound condensate.  Salts of condensates of formaldehyde with a naphthalene sulphonic acid, a methylnaphthalene sulphonic acid or a tetrahydronaphthalene sulphonic acid are preferred.  In an example cotton fabric is padded in an aqueous solution containing sodium pentachlorophenate, cetylpyridinium bromide, and a fatty alcoholethylene oxide condensate.

Title: Manufacture of pyridine dyestuffs
IPC: C09B57/00
Filed: 1934-10-17
Abstract: Dyestuffs giving greenish yellow shades on wool and silk and acetate silk are prepared by sulphonating p-alkyl or aralkylaminophenyl pyridines or their corresponding quaternary pyridinium compounds and when the latter are not used converting the products into quaternary pyridinium compounds.  The conversion into pyridinium compounds and the sulphonation may also be effected in a single operation, e.g. by treating with chlorbenzylsulphonic acid or chlorethanesulphonic acid. In examples: (1) p-dimethylaminophenylpyridine is treated with benzylchloride and the quaternary compound sulphonated with sulphuric acid; the starting material may also be first sulphonated with fuming sulphuric acid and the sodium salt of the product treated with benzylchloride; (2) p-diethylaminophenylpyridine and p-methylbenzylaminophenylpyridine are similarly treated with benzylchloride and then sulphonated; (3) p-methylbenzylaminophenylpyridine is sulphonated with fuming sulphuric acid and the sodium salt of the product treated with benzylchloride, diethyl-sulphate or ethyliodide.  p-Alkyl and aralkylaminophenylpyridines may be prepared by heating alkyl or aralkylanilines with a mixture of pyridine and benzoylchloride in the presence of "natural copper C."  A sample furnished under Sect. 2 (5) comprises a product obtained by sulphonating a benzylpyridinium chloride prepared from p-dimethylaminophenylpyridine by nitrating with nitric acid containing sodium nitrite and benzylating with benzylchloride.

Title: Rotary shear drive
Inventor: HALLDEN KARL WILLIAM
IPC: B23D25/12
Filed: 1968-06-24
Abstract: 1,212,239. Shearing. HALLDEN MACHINE CO. 24 June, 1968, No. 29971/68. Heading B3W. A rotary shear, Fig. 2, comprises shear drums 12, 14 having shear blades 16, 15, a driving shaft 22, a driven shaft 20 and gear pairs 36 and 38 mounted on the shafts, the gear arrangement being such that backlash is taken up in the gear pairs in a manner to distribute the total gear load over both gear pairs, the total gear load including driving torque transmission to the driven shaft, locking the shear drums against clash approach of their blades and operational separation of the shear blades during cutting action. All the gears are helical. For accurate adjutment of the blades 15, 16, gear 38a is axially adjustable relative to the gear 38b by being splined at 40 to the shaft 20 and is lockable in adjusted position by means 42. The gear 38a also acts as a backlash take-up gear, being formed in two axially relatively adjustable parts 44, 46. Part 44 is directly splined to the shaft 20 at 40 and part 46 is splined at 48 to a hub 50 on part 44 and movable relative to part 44 by means of screws 52. The part 46 is adjusted until a tooth 54 on part 44 bears against the flank 60 of the nearest tooth 58 on gear 38b in one direction of rotation and a tooth 56 on part 46 bears against the flank 60 of the nearest tooth 58 in the other direction of rotation. Driving torque applied to the lefthand end of the shaft 22 is transmitted directly to the shear drum 12 and through gears 36 only to the drum 14. The gear pair 38 lock the drums against clashing approach and operational separation of the blades. In another embodiment, Fig. 8, gear backlash is taken up in either direction in an adjustable coupling 86. On relatively adjusting coupling elements 82 and 84 in the direction for backlash take-up as shown in Fig. 8, driving torque is transmitted to drum 14a through gears 36<SP>1</SP> and shaft 20a and to drum 12a via gears 36<SP>1</SP>, shaft 20a and gears 381. Gears 381 lock the drums against clashing approach of the blades and gears 36<SP>1</SP> against operational separation during cutting action. When backlash is taken up in the other direction (not shown), torque transmission is through shaft 22a to drum 12a and through shaft 22a and gears 38<SP>1</SP> to drum 14a. The other functions of the gears 36<SP>1</SP> and 38<SP>1</SP> are the same. Since only one flank of a tooth of a gear is in contact with one flank of a tooth of the other gear of a pair at any one time there is a degree of resilient torsional give in the shafts 20a, 22a. The embodiment of Fig. 8 also has a miss-out function, the shaft section 76 carrying lower drum 12a being journalled in spaced slide blocks (104), Fig. 7 (not shown), guided vertically in the shear frame (108) and pivotally connected to rods (112) eccentrically mounted on a shaft (116) which remains idle for each miss-out action. Universal drive connections 94, 96 ensure continuous drive of the lower shear drum 12a during cutting and miss-cutting.
