Title: A process for forming or shaping the operative surface of abrasive laps
IPC: B24D18/00
Filed: 1945-02-09
Abstract: 594,718. Forming or shaping operative surfaces of abrasive laps. KNOWLSON, R. F. Feb. 9, 1945, No. 3354. [Class 60] To form or shape the operative surface of an abrasive lap containing an abrasive such as diamonds or tungsten carbide, a form roller or plate having the profile which it is desired to reproduce on the abrasive lap is rapidly vibrated against the abrasive lap while the abrasive lap is reciprocated underneath the vibrating form roller or plate. The lap'3 carried by a reciprocating slide 2 mounted on the machine frame 1 is acted on by a form plate 9 or roller, carried by a slide 7 which is rapidly reciprocated by a vibrator 15 mounted on a slide 8 carried by a housing 4 and fed by a screw 10. The vibrations may be as rapid as 10,000 per minute. When a form roller is used, this is preferably positively rotated, relatively slowly, and preferably at substantially the same surface speed as the lap is reciprocated. Specification 565,284 is referred to. The Provisional Specification refers to the dressing of grinding-wheels by a rapidly vibrating former or roller.

Abstract: 775,510. Wrapping-machines. KIMBERLEYCLARK CORPORATION. Feb. 8, 1955 [Feb. 25, 1954], No. 3754/55. Class 94(1). Apparatus for wrapping a web of sheet material about an article comprises means constraining the web to follow a path including two sections at an angle to each other to form a dip, the second section in the line of web travel having means for folding the sheet about the article. The described machine, for forming sanitary napkins comprises a. conveyer 30 forwarding a fluff mat 24, positioned on a crÛped wadding sheet 22, to a feed table 26. The sheet and mat are traversed by a conveyer 40 beneath a restraining member 158 onto a folding board 28. Secured to the board 28 are co-planar folding paltes 136, 138, the former producing the first fold of one side of the sheet over the mat and the latter folding the other side over the first side to produce the complete package. Rods 156 pivoted to the member 158 and to the machine frame guide and give support to the sheet. The angle between the parts 26, 28 is adjustable. It is stated that the conveyer may be replaced by other known feeding means, or that with wrapping materials capable of supporting their own weight, the feed table and sheet supporting part of the folding board might be eliminated. Also that the folding board and/or feed table might be formed in portions at an angle to each other. The dip in the path of travel is stated to prevent angular off setting of the folded parts of the web relative to its article supporting part.

Abstract: A liquid composition, suitable as a jetturbine lubricant, comprises (1) a tetra-alkyl orthosilicate, and (2) a complex ester condensate of a monohydric alcohol, a glycol and a dicarboxylic acid.  The viscosity index and viscosity at 210 DEG  F. of the composition may be increased by the inclusion therein of a polyalkyl methacrylate. The composition may also include, as an oxidation inhibitor for the composition (or components thereof) in the liquid phase, an amine having at least one aromatic nucleus with two or more condensed aromatic rings (e.g. phenyl alpha naphthylamine), an alkyl phenyl amine, diphenyl amine, an alkyl phenol (preferably having at least two alkyl radicles in the 2, 4 or 6 positions to the OH radicle and at least two alkyl radicles being linked to the aromatic nucleus through a tertiary carbon atom), alpha or beta naphthol, an alkylated naphthol, phenol or naphthol containing ether or thio-ether linkages, or a polyhydric alkyl benzene or naphthalene (e.g. alkylated catechol).  In order to inhibit oxidation of thermal decomposition products in the vapour phase, the liquid composition may also contain an organic selenide or telluride of formula R-(X)m-R1, wherein X is selenium or tellurium, m is an integer and R and R1 are saturated or unsaturated aliphatic or cycloaliphatic groups which may carry aromatic substituents (e.g. phenyl, hydroxyphenyl or aminophenyl groups).  A list of suitable dialkyl mono- and di-selenides and tellurides is given.  In the examples, liquid compositions are described consisting of (i) tetra-(2-ethyl hexyl) orthosilicate and complex ester A (derived from sebacic acid, 2-ethyl-hexanol and 2-ethyl-1,3-hexane diol) with or without phenyl alpha naphthylamine; (ii) tetra-(oxoiso-octyl) orthosilicate, complex ester A and acryloid HF-855 (polymerized n-octyl methacrylate dissolved in light petroleum oil) with or without phenyl alpha naphthylamine; and (iii) tetra-(oxo-iso-octyl) orthosilicate, complex ester A, phenyl alpha naphthylamine and dilauryl selenide with or without acryloid HF-855.

[Class 92 (i)] Relates to levelling devices for guns mounted on unstable platforms of the kind in which the gun E is adjustable in training about an axis perpendicular to the base A, and in elevation about a trunnion axis x which can be turned for cross levelling about a third axis formed by a shaft C. According to the invention, a levelling device, including right-angle slides F<3>, F<5> and an upstanding lever G, engages a member G<1> coaxial with the third axis at the point where this axis meets the training axis. The lever G is shown connected by a rod H<1> to the gun cradle arm D and by a rod H to a sight H<0> carried by the shaft C. The frame F carrying the slides is arranged on a vertical pivot M fixed to the base A and by means of a lever F<1> can be locked either to the base or to rotating carriage B. The right angle slides may be controlled by a gyroscopic horizon device fixed to the base A when the frame F is fixed to the base or by an inertia device on the carriage B when the frame is locked to the carriage as shown. The slides may also be controlled from a tri-axial control post pivoted similarly to the gun. To permit of hand adjustment with gears K, D<1>, the link H<1> is removed and a clutch L is operated to disconnect the member G<1> from the shaft C.

The invention comprises compounds of the general formula wherein both the groups Y are identical and Y is -COOR, -COOH or -H, and R is a hydrocarbon group, and the monohydrate of the compound wherein Y is -COOH. The compounds wherein R is -COOR are prepared by reacting a compound of the formula with a diester of acetylene dicarboxylic acid at an initial temperature below 0‹ C. Hydrolysis of the esters with 50% H 2 SO 4  gives the compound in which Y is -COOH, which compound is isolated as its monohydrate. Decarboxylation of this monohydrate using copper powder in quinoline gives the compound in which Y is H. Pentafluorothiophenol is prepared by treating pentafluorobenzene with n-butyl-lithium and adding flowers of sulphur to the resulting mixture.
