Title: Self-Aligning Bearings with improved Lubricant Arrangements
Inventor: YOUNG ROY WHEELER
IPC: F16C23/04
Filed: 1967-06-20
Abstract: 1,185,718. Bearings; lubricating. R. W. YOUNG. 20 June, 1967 [21 June, 1966; 13 June, 1967], No. 26158/69. Divided out of 1,185,717. Heading F2A. A self-aligning bearing 21, Fig. 1, has a lubricant reservoir 34 which is connected by means of a duct 35 to bearing surfaces 24, 37 of outer members 23, 39 respectively and to bearing surfaces 26 of a part-spherical-shaped bearing member 27. A diaphragm 30 divides the reservoir 34 so that, when lubricant is introduced into a portion 32 of the reservoir, via a fitting 38 and a passage 40, the diaphragm is deflected outwardly into a portion 31 of the reservoir. The diaphragm, which tends to deform inwardly, then urges lubricant from the portion 32, through the duct 35, to the bearing surfaces 24, 32 and 26 of the members 23, 39 and member 27 respectively. In another embodiment, a reservoir 72, Fig. 2 (not shown), is formed in a partspherical-shaped member 74; the reservoir 72 contains a member 78 which is urged by a spring 82 so as to provide the bearing surfaces with lubricant. In a further embodiment a reservoir 124, Fig. 3 (not shown), is formed in a shank 122 of a rod-end bearing assembly 110. In yet a further embodiment a reservoir 166, Fig. 4 (not shown), is formed in a shaft 162 which is mounted in a part-spherical-shaped bearing member 152.
Patent GB-338617-A (GB)
Title: Improvements relating to signalling systems and in particular to radio communication
IPC: H04J1/00
Filed: 1929-08-28
Abstract: 338,617. Harries, J. H. O. Aug. 28; 1929. Multiplex systems; transmitting systems; television systems.-In order to avoid overlapping of signals, in wireless multiplex systems, one signal is sent as a carrier w1 and lower side-band of width p1, and another on a slightly higher carrier w2 and upper sideband (of width p2). The gap s between the two carrier frequencies is less than the highest modulating frequency comprised in p1 or p2. In this way the band occupied by the pair of signals is p + s + p2 which is less than the width 2p1 + 2p2 which would be occupied by two ordinary transmissions. Further pairs of transmissions situated outside this band may be employed. A pair of transmissions may be used for sending a television picture in two sections, and the intervening space of width s may be used for the synchronizing signals. In order to enable one of the side-bands to be more completely suppressed, modulation and side-band suppression may be effected at a comparatively low frequency which is subsequently raised to a desired radiating frequency, as described in Specification 328,680. In a wireless telephone system incomplete suppression of a side-band would accentuate the low notes at the receiver, but this may be neutralized by designing the receiver to favourize the higher notes. Preferably the lower frequencies of the modulating current are removed before modulation. The receiver is preferably of the heterodyne or frequency-changing type, as the reduction of frequency enables filter circuits to separate the signals more effectively.

Abstract: 265,224. I. G. Farbenindustrie Akt.- Ges. Jan. 28, 1926, [Convention date]. N-Arylsulphoisatins; isatins; naphthisatins.- N-Arylsulpho derivatives of aromatic amines are condensed, in the form of their salts, with oxalyl chloride in presence of an inert diluent; the oxamic acid chlorides so prepared, when treated with acid condensing agents such as aluminium chloride, yield N-arylsulphoisatins which in turn give the isatins themselves on saponification. According to examples the following compounds are obtained :-(1) N-p-toluenesulpho-5-methylisatin from p-toluenesulpho-p-toluidine, (2) a mixture of the N-p-toluenesulpho-derivatives of 4- and 6-methylisatins from p-toluenesulpho-mtoluidine, (3) N-p-toluenesulpho-1 : 8-naphthisatin from p-toluenesulpho-1-naphthylamine, (4) a mixture of the N-p-toluenesulpho-derivatives of 5-methyl-6-chlor- and 5-methyl-4-chlor-isatins from p-toluenesulpho-3-chlor-4-toluidine; saponification to the corresponding isatins is effected by means of concentrated sulphuric acid, or in one case by means of caustic soda. Sodium salt of p-toluenesulpho-3-chlor-4-toluidine is obtained by fusing 3-chlor-4-toluidine with p-toluenesulphochloride and sodium acetate.

Title: The manufacture of carbohydrate derivatives
IPC: C08B15/06
Filed: 1926-10-30
Abstract: 286,332. Harrison, W. Oct. 30, 1926. Starch and other carbohydrate derivatives. - Stable and permanent derivatives of starch and other carbohydrates are obtained by oxidizing a carbohydrate compound containing the CSS group, in the presence of an organic derivative of ammonia in which at least one atom of hydrogen is reactive ; one or both of the other hydrogen atoms may be replaced by an alkyl, aryl, or aralkyl group, or by an oxy- or hydroxy-, alkyl-, aryl-, or aralkyl group. The carbohydrate compound and the ammonia derivative may be mixed together before the addition of the oxidizing agent. Suitable ammonia derivatives are :- alkylamines, arylamines such as aniline, aralkylamines, acid amides such as acetamide. benzamide or phthalimide, amino acids such as aminoacetic acid, amidines. urea and its derivatives, cyanamide, dicyanodiamide, dicyanamide, guanidine and its derivatives, urethanes, and thiourea and its derivatives. The reaction may be carried out under alkaline, neutral or faintly acid conditions; and it may be conducted at normal temperature or at raised temperatures up to 100‹ C. ; when carried out at low temperature the products appear to be derivatives of diimido carboxylic disulphide, whereas at 100‹ C. they appear to be derivatives of benzothiazol. The oxidizing-agents used are such as will oxidize sulphuretted hydrogen ; they may be ferricyanides, bichromates, chlorates, hypochlorites, peroxides, nitrous acid, sulphurous acid, ferric salts, and air or oxygen with or without oxygen carriers; when air or oxygen is employed, this must be blown through the mixture, or the oxygen may be used in the nascent state as produced by electrolysis of the solution. In examples, the starting material is starch xanthogenate, and the reaction is carried out either in the alkaline solution, or after neutralizing with acetic, carbonic, sulphurous or phosphoric acid; the ammonia derivative is aniline, toluidine, methylaniline, or urea ; the products either separate out of themselves, or are separated out by acidifying the mixture ; and either during or after the formation of the carbohydrate compound it is treated with acetone, carbon disulphide, sodium sulphite, or other solvent for sulphur. The products obtained may be dissolved in caustic alkalies, or in cellulose solvents such as zinc chloride, sulphuric acid, and ammoniacal copper solution; and they may be worked up into films, filaments, filling materials. &c. Specifications 27732/12, [Class 2 (ii), Cellulose &c.] ; and 286,331 are referred to.
