In the arrangement of Fig. 2, the stereo-pictures 3 and 4 are viewed through lenses 1, 2 rotatable Amici prisms 5,6, rotatable panfocal lenses 9,10, and finally through ocular lenses 11,12, the images of the pictures appearing in the focal planes 13,14 of the ocular lenses. A third ocular lens 17, identical with 11 and 12, is mounted so that it can be positioned either to the left (as shown in full lines) or the right (dotted lines) of the other oculars. The ocular 17 carries at its focal plane a frame 18 on which can be mounted a part 19 of the reference transparency or print on which is marked the spot (e.g. a small black dot) to be located. It may be illuminated by lamp 21 from behind, or lamp 22 from in front, and can be rotated in its own plane by a knob 20. Viewing through oculars 17 and 11, stereoscopic fusion between pictures 19 and 3 can be effected by turning knobs 7 and 20, which orient the pictures, and knob 15 which adjusts the two images to the same size. By placing the ocular 17 in the dotted line position, the pictures 19 and 4 can be viewed together. If no provision is made for altering the image magnification (i.e. lenses 9,10 are not of the adjustable panfocal type),the picture 19 must be an appropriate reduction or enlargement. In the simpler form of Fig. 1 (not shown), no additional ocular lens 17 is provided, and the frame 18 is mounted so that the picture 19 is viewed directly through ocular lens 11.

Title: Improvements in or relating to machines for cutting fabric
IPC: D06H7/02
Filed: 1920-07-10
Abstract: 148,859. Maimin & Co., H., (Assignees of Maimin, H.). June 18, 1915, [Convention date]. Cutting - appliances.- Relates to means for sharpening the lower cutting-edge of the knife. of a hand-directed powerdriven fabric - cutting machine, of the kind having a vertically reciprocating knife sliding in a standard and having a cutting edge along its exposed side and another at its lower edge, without removing the knife from the machine. The invention is set forth with reference to the cutting machine described in Specification 100,740. Normally, the back edge 8 of the knife 7 bears upon the bottom 6 of the guide-slot in the standard 2. For sharpening, the knife is moved laterally, into the position shown, with its lower edge clear of the standard. The top of the standard is formed as a guideway for the lower part 4 of the head of the machine, comprising the motor and the driving-gear, and an arm 21 is pivoted to it; the boss of this arm is formed with cam-faces which bear upon corresponding cam-faces on the member 14 which supports the pivot pin 20 and is secured to the head; the arm is prevented from moving axially by the engagement of a collar 22 thereon with a recess in the top of the standard, so that when it is turned, the head of the machine is moved laterally, carrying with it the knife. The grinding-blocks 51, 52 are secured in sleeves free to rock under the control of springs and stops on arms 47, 48 projecting from sleeves which are themselves free to rock on arms 41, 42 of a frame 34. This frame is pivoted at 33 to extensions 31, 32 of an arm 26 which is pivoted at 27 to the arm 21; a spindle 36 mounted in the frame is driven by a crank-handle 38 and carries a cam 39 which engages in the fork end of the extension 32, whereby the frame is caused to rock on its pivot from C to D, Fig. 3, with a dwell at each end of the stroke. Another cam 65 on the spindle engages the fork of one arm of a three-armed lever 61 pivoted to the frame 64 at 62, the other forked arms of which engage with the arms 47, 48 of the grinding-blocks; the cam 65 is so disposed in relation to the cam 39 that each block is moved upwardly in contact with the corresponding cutting-edge while the frame is at rest. Arms 67 ensure the correct positioning of the sharpening- device in relation to the standard. When the sharpening is completed, the sharpener is swung away from the standard about the pivot 27; the arm 21, with the entire apparatus, is then swung upwards about the pivot 20 into the position shown in dotted lines, in which it is retained by the catches 68, 69. This movement restores the knife to its working position in the standard. In a modification the grinding blocks may move downwardly in contact with the knife edge.

Abstract: 1,138,308. Resins and compositions. INSTITUT FRANCAISE DU PETROLE, DES CARBURANTS ET LUBRIFIANTS. 11 May, 1966 [11 May, 1965], No. 20961/66. Heading C3R. Solid resins are prepared by reacting an aldehyde with a " heavy residue " from the production of a conjugated diolefin by cracking an alkylmetadioxan, then reacting the product with a phenol. The heavy residue preferably derives from cracking of 4-methyl-, 4 :4-dimethyl-, 4:5-dimethyl-, and 4-ethyl-metadioxans, and may also contain similar residues from the preparation of the metadioxan. The chief characteristics of the heavy residues are: b.p. 140-250‹ C., M.W. 150-250, hydroxyl number 30-90, bromine number above 60, e.g. 90-180, flow point below 0‹ C., composition C = 75-86 %, H = 7-12%, O = 5-10%. Suitable aldehydes are C 1-3  saturated aliphatic aldehydes, e.g. formaldehyde, formalin, paraformaldehyde, acetaldehyde, and propionaldehyde. Suitable phenols may be substituted by alkyl, aryl, ether, carboxyl, sulphonic groups or halogen and are, e.g. phenol, o- and mcresol, 1:3 :5-xylenol, 2-butylphenol, 3-benzylphenol, 3:5 - diphenylphenol, 3 - cyclohexylphenol, resorcinol, the bisphenols, 3-chlorophenol, 3-methoxyphenol, salicylic acid, 3- phenolsulphonic acid. The reaction with aldehyde and the. reaction with phenol are both preferably conducted at 60-200‹ C., in the presence of Lewis acid and Friedel-Crafts type catalysts, e.g. phosphoric acid, sulphuric acid, hydrochloric acid, phenolsulphonic acid, SnCl 4 , FeBr 3 , SbF 3 , BF 3 , ZnCl 2 , AlCl 3  as such or in aqueous solutions which may be 0À1-7 N. Thus the first reaction may be conducted in 3-7 N aqueous acid, the second in 0À1-2 N acid, or both may be conducted in acid of less than 2 N. No catalyst is required when the phenol is phenolsulphonic acid. Preferred ratios of reactants are : to each p.b.w. of heavy residue, 0À1-10 p.b.w. of aldehyde and 0À1-10 p.b.w. of phenol. The resins may be cured by heating with an aldehyde. In examples a heavy residue of b.p. 150‹ C. and Br number 160 from the cracking of 4:4-dimethylmetadioxan is reacted with phenol i.p.o. sulphuric acid or 85% phosphoric acid. In Examples 5 and 6 heavy residues are used from the cracking of 4-methyl- and 4:5-dimethyl-metadioxan, of b.p. 140‹ and 180‹ C. and Br numbers 145 and 150 respectively. In Example 4 the phenol is phenol sulphonic acid. In Example 2 a moulding composition is prepared from the resin, hexamine, wood flour, zinc stearate, stearic acid, wax, lime and a colouring matter.

Title: An improved manufacture of additives for lubricants
Filed: 1948-08-09
Abstract: Sulphurized products obtained by reacting an aliphatic or alicyclic hydrocarbon containing an unsaturated carbon-to-carbon linkage with a sulphur halide are dehalogenated by heating 1 molecular proportion of the said product in the presence of substantially 0.1 to 2 molecular proportions of a secondary or tertiary saturated monohydric aliphatic alcohol having 4 to 16 carbon atoms per molecule at a temperature in the approximate range of 100 DEG  to 320 DEG  F., preferably 175 DEG to 285 DEG  F.  The sulphurized products are not completely dehalogenated but the halogen content is lowered sufficiently to enable them to be used with advantage as additives for lubricating oils.  Hydrocarbons specified are olefines such as propylene, butylenes, diisobutylenes, triisobutylenes, the codimer of isobutylene and n-butylene, cracked gasoline fractions, cracked paraffin wax, viscous olefine polymers, e.g. medium or high molecular weight polybutene, cyclopentene, cyclohexene, butadiene, pentadiene and isoprene.  Acetylenic hydrocarbons may also be used.  Sulphur halides used are the dichloride and especially the monochloride. Olefines and sulphur halide are generally reacted in mol. ratios of 3 : 1 to 1 : 1 at 70-125 DEG  F.  The dehalogenation is conveniently carried out at the reflux temperature of the alcohol and the greater portion of the substance has reacted after about half-an-hour. Alcohols specified are sec.-butyl, tert.-butyl, isoamyl, 2-ethylhexyl alcohol and methyl-cyclohexanol.  In an example excess diisobutylene is treated for an hour with sulphur monochloride at a temperature not above 130 DEG  F., stirred for 2 hours and heated at 230-280 DEG  F. with 10 per cent of its weight of 2-ethyl-hexanol for 4 hours when after vacuum distillation to remove diisobutylene the product is found to contain 2 per cent of chlorine as against a figure of 10.5 per cent for the untreated sulphurized product.  Methylcyclohexanol may be used in place of p  the alcohol used in the above example. The Specification as open to inspection under Sect. 91 also refers to the use of derivatives of the above hydrocarbons such as olefines containing aromatic nuclei, halogen atoms and nitro groups.  This subject-matter does not appear in the Specification as accepted.
