Class 80 (2) [Also in Group VIII] A clutch collar 264 in the drive of a machine for roughing shoe soles (see Group VIII) is urged by the action of internal springs into frictional driven relation with the face of a driving pulley 254 when a 'shifter lever 348 is released from its engagement with a spring- loaded latch 350 mounted in a tube 354 pivoted on a belt-crank 358. The actuation of the starting lever of the machine operates through linkage to permit a spring 408 to set a hook 366 into engagement with the end of the latch (which projects through a recess in the lever 348) and, when later in the machine cycle a lever 400 swings forwardly the link 394 carrying the hook, the latch is moved so that its shoulder 352 is disengaged from the lever. Towards the end of the cycle, a cam 362 acts upon a roll 360 on the bell-crank 358 to re-set the latch and through the lever 348 cause the collar 264 to engage a braking flange 266.

Filed: 1973-07-11
Abstract: 1382018 Aerials WESTINGHOUSE ELECTRIC CORP 11 July 1973 [4 Aug 1972] 33016/73 Heading H4A An aerial arrangement for operation in a first higher and in a second lower frequency band (e.g., 9 to 10 GHz and 1À8 to 2 GHz) comprises a plurality of array elements each including an opening 46, Fig. 5, in a conductive strip 44 and an open waveguide portion, having side walls 45, 47, with an element 48 (monopole or dipole) transversely disposed therein. Radiation due to the opening 46 is in the first frequency band, and is horizontally polarized. Radiation due to the element 48 is in the second frequency band, and is vertically polarized. Further decoupling between the radiating elements is provided by spacing the side walls 45, 47 sufficiently close together so that the cut-off frequency of the waveguide is higher than the highest frequency of the first frequency band. As shown in side view in Fig. 2, in which the conductive strip is referenced 20, the opening 22, the side walls 16, 17, and the transverse radiator 24, the latter is a monopole located approximately below the opening. It extends upwardly from the wall 17 into a hole in the wall 16, and the conductors of a feed line are connected to the upper end of the monopole and to the rim of said hole (Fig. 3, not shown). In a dipole arrangement, tubular and cylindrical members extend respectively from the walls 16, 17 towards the centre of the waveguide (Fig. 4, not shown). The waveguide has an end wall 26 which is so spaced from the element 24 that all radiation is directed outwardly. All array elements may be individually fed, in both frequency bands.

[Also in Divisions C1 and G2] A glass fibre suitable for use as a Faraday effect element, e.g. in an optical isolator, contains oxides of lead, silicon and one of thallium and caesium, the concentration of the thallium or caesium oxide decreasing towards the surface of the fibre so that the refractive index n r  of the fibre decreases from the centre to the surface according to the law n r  = n 0 (1 - ar<SP>2</SP>) where r is the distance from the fibre axis, n 0  is the refractive index at the axis and a is a constant, so that divergence of the light is minimized. The fibre may be straight and disposed within a helical electrical conductor (solenoid) or the conductor may be straight and disposed within a helical fibre, Figs. 3 and 4 (not shown). The fibre is produced from one of uniform refractive index by substituting some of its constituent ions by others having a smaller ratio of electronic polarizability to (ion radius)<SP>3</SP>, e.g. by immersion of glasses containing thallium, or thallium and sodium, or caesium and sodium, or terbium and thallium, in a KNO 3  bath at 400‹ C. The distribution of lead ions in at least two examples appeared unaffected by this method and Vedet's constant appeared to be substantially uniform across such fibres.

Title: Improvements in or relating to alkali cellulose and preparation of cellulose ethers therefrom which give smooth solutions
IPC: C08B11/00
Filed: 1960-09-30
Abstract: Cellulosic material is contacted with aqueous alkali in the presence of an inert organic diluent at temperatures of from 0 DEG  to 30 DEG C. for 1 to 3 hours, the weight ratio of diluent to cellulosic material being from 6 to 19 parts diluent to one part cellulosic material, said diluent comprising by volume (a) 70-96% of a water miscible inert organic compound selected from aliphatic alcohols having 2-5 carbon atoms, dioxane, tetrahydrofuran, and acetone, (b) 0-16% of a second water miscible inert organic compound different from (a) and consisting of methyl alcohol, ethyl alcohol, or acetone, and (c) 4-15% water, the resulting alkali cellulose being etherified if desired to form the ether.  A preferred diluent composition consists of isopropyl alcohol or tertiary butyl alcohol or a mixture of either of these alcohols with methyl or ethyl alcohol.  The aqueous alkaline solution may be added to the cellulose and diluent in one or two stages.  Thus all the caustic alkali may be added at the start of the alkali cellulose period, or alternatively, only a portion of the caustic alkali may be added at this stage, the remainder being added at the commencement of the etherification period.  From the alkali cellulose so made, cellulose ethers may be obtained by the conventional slurry method, the aqueous solutions of which exhibit very low granularity, thixotropy and gel strength. Examples describe the manufacture of sodium carboxy methyl cellulose by treating the alkali cellulose so made with a 55% by weight solution of monochloracetic acid in 87% by weight aqueous solution of isopropyl alcohol at 70 DEG C. for 90 minutes.  The product is neutralized with glacial acetic acid, washed with aqueous methanol, centrifuged, vacuum-dried and pulverized.  Alkali cellulose made according to the invention, is stated to be useful in preparing all types of water-soluble and alkali-soluble cellulose ethers, e.g. hydroxyalkyl, carboxyalkyl, sulphoalkyl, and alkyl celluloses and cyanoethyl, carboxymethyl hydroxyethyl, carboxymethyl methyl, and methyl hydroxyethyl celluloses.

Title: Method of making 2-tertiarybutyl-4-alkoxy-phenols
IPC: C11B5/00
Filed: 1954-11-24
Abstract: 2 - Tertiarybutyl - 4 - alkoxy - phenols are prepared by a process which comprises effecting incomplete monoetherification between monotertiarybutyl-hydroquinone and an alkyl etherifying agent under alkaline conditions at a temperature below about 30 DEG  C. in an inert reaction medium in which both the reactants and the reaction products are at least partially soluble at the reaction temperature, and then separating the 2-tertiarybutyl-4-alkoxy-phenol from the reaction mixture.  The process minimizes the formation of the 3-tertiarybutyl isomer and the dialkyl ethers.  The molar ratio of monotertiary butyl-hydroquinone to alkyl etherifying agent is preferably at least one.  Preferably, the amount of etherifying agent or the reaction time is so regulated that the degree of monoetherification is not substantially in excess of 70 per cent. The unreacted mono-tertiary-butyl-hydroquinone is recovered and may be recycled together with fresh reactants in a cyclic process. The reaction is preferably carried out under slightly reducing conditions, e.g. obtained by the addition of zinc or sodium bisulphite, and/or under a blanket of inert gas such as nitrogen. The alkyl etherifying agents specified are di-methyl or -ethyl or -propyl or -butyl sulphates, methyl or ethyl or propyl or butyl acid sulphates and methyl or ethyl or propyl or butyl chlorides and phosphates.  Specified alkalies are sodium, potassium and barium hydroxides.  The alkaline hydroxide is preferably employed in a ratio of one mol. per mol. of etherifying agent.  Specified inert solvents are dioxane and methanol, aqueous methanol being preferred.  In examples, mono-tertiary-butyl-hydroquinone is reacted with dimethyl sulphate to give 2 - tertiary - butyl - 4 - methoxyphenol. Specifications 761,613 and 763,146 are referred to.
