Abstract: 779,853. Statistical apparatus. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 20, 1955 [Dec. 24, 1954], No. 36443/55. Class 106 (1). Punched record cards are sensed in a device having means for feeding the cards intermittently to a pair of sensing stations 14, 15 on a circular track, continuously rotatable reading brushes 21 for intermittently sensing the cards and a fixed cam 28 co-operating with the rotatable brush carriers for causing the brushes to be radially extended into operative position or retracted therefrom. The reading brushes 21 are mounted on blocks 22 secured by arms 23 to rocking shafts 20. These shafts have bearings in arms 19 secured to the central shaft 18 and cam follower arms 26 on the shafts 20 coact with cams 28 secured to fixed sleeves 30. Spindles 25 are mounted parallel to shafts 20 on arms 24 freely movable on shafts 20 and adapted to be displaced in an anti-clockwise direction against the action of springs, by the engagement of pins 35 on arms 23. The shafts 20 carry idle gears 33 at the ends meshing with gears 31 fixed to sleeve 30. Spindles 25 have gears 32 fixed to their ends meshing with the gears 33 so that as the brushes revolve, the spindle 25 is rotated. Pressure discs 46 attached to the spindles 25 engage each card 12 during sensing and force it against the contact strips of the sensing stations 14, 15. For an 80-column card, 79 discs are provided, one bearing between each pair of columns. The brushes 21 bear on the card between the discs. As the brush carrying assembly revolves, the cam 28 causes the brushes and the discs 46 to be extended to co-operate with the cards as they pass the sensing stations. The cards are fed to the sensing stations by drums 37 rotatably mounted on bearings 44 and having cut away edges 36 covered with a frictional material 38 to provide a grip track for the cards. A series of spring pressed rollers 10 keep the cards pressed against the track so that the cards are advanced as the drums rotate. The drums are driven intermittently by gear mechanisms acting through gear rings 43. The apparatus may be used to compare successive cards of a series so as to detect a change of group.

Title: Process for dewaxing hydrocarbon oils
IPC: B01J20/22
Filed: 1961-09-21
Abstract: Hydrocarbon oils, for example middle distillate fractions boiling in the range 250-700 DEG F. and lube oils, are dewaxed in a process which comprises adding 0.001-0.5% wt. of an ethylene-vinyl acetate copolymer to the wax-containing hydrocarbon oil prior to filtering the precipated wax from the oil.  The copolymer may comprise 1-40% wt. vinyl acetate and 60-99% wt. ethylene, and may have a molecular weight of 800-3000.  The copolymer acts as a filter aid, and may thus be employed in conventional propane/butane, MEK/toluene, and MEK/MIBK dewaxing processes. Prior to filtration, solvents which reduce the viscosity and aid in the filtration, e.g. low boiling liquid paraffins, light petroleum oils, ketones or aromatic compounds, such as propane, benzene, toluene, acetone or higher ketones, and mixtures thereof, may be added. For example, a propane/butane mixture in an amount of 1-9 vols. of solvent per vol. of oil may be added and the filtration effected at - 20 DEG  F. to - 40 DEG  F., or a methyl ethyl ketone/toluene mixture may be employed, filtration being effected at +20 DEG  F. to - 20 DEG  F.

Abstract: 1,080,987. Coupling devices in tubular diaphragm machines. P. R. L. ROUDAUT. Sept. 11, 1964 [Sept. 30, 1963; April 6, 1964], No. 37292/64. Heading H2A. [Also in Division F1] A tubular diaphragm pump has rings 2 of magnetic material distributed along the length of diaphragm M and a co-operating magnet system comprising magnet 5a with polepieces 6a, 7a helically disposed along tubular sealing element 1 to attract the diaphragm rings 2 such that when the magnet system rotates liquid is pumped in the direction of the arrows. The volume of liquid pumped may be altered by varying the helix angle of the magnet system. As shown, piston 9 carries a second magnet system having magnet 5b and polepieces 6b, 7b forming an opposite helix to the first system. If fluid pressure is applied to the right-hand face of piston 9 it will move to the left thus reducing the volume pumped until, when both helices are equally expanded, the flow is stopped; further movement will increase flow in the reverse direction. In a modification the rotating magnet system is within the diaphragm and the pumping action takes place between the outside of the diaphragm and the casing of the pump. A further modification (Figs. 3 and 4, not shown) uses secondary rings which bear against closely spaced rings embedded in the diaphragm together with a magnet system in which identical magnet assemblies are loosely supported on the shaft and angularly orientated by a coarse pitch helical spring which has one end fixed and the other attached to a sliding piston so that the helix angle may be varied. Electromagnets may be used instead of permanent magnets throughout.

Title: Improvements in or relating to the manufacture of paints
IPC: C09D167/00
Filed: 1929-12-06
Abstract: A paint comprises an inorganic or organic pigment or dyestuff in suspension in an aqueous emulsion of an emulsifying agent and a synthetic resin containing the radicles of a polybasic acid, a monobasic acid, and a polyhydric alcohol.  The resins may be obtained from alcohols such as glycerol, glycol, polyglycerols and polyglycols, glycerol ethers, pentaerythrite, mannitol, sorbitol, &c., by simultaneous or successive esterification with monobasic acids such as palmitic, oleic, stearic, linoleic, eleomargaric or abietic acids or recinoleic acid or its dehydration products &c., and polybasic acids such as phthalic, trimellitic, succinic, maleic, diglycollic or thiodiglycollic acids.  Resins containing acids with more than one double bond possess drying properties and are especially valuable.  As emulsifying agents known agents may be used, such as alkali metal sulphonates of polyalkylated hydrocarbons, for example salts of di-isopropyl or dibutyl naphthalene sulphonic acids, salts of sulphonated tar oils, or of sulphonated fatty acids. Ammonium salts of aliphatic high molecular carboxylic acids such as wax acids, montanic acid, rosin acids or of alkali soluble proteins such as casein may also be used.  Ammonium salts or salts of easily volatile amines, if used, evaporate after application of the paint, liberating acid and giving water resistant properties to the paint. The paints may be made by mixing the resin with an aqueous solution of the emulsifying agent and incorporating the pigment therewith. Soft resins may be mixed without the aid of a solvent, whereas hard resins are dissolved in a solvent.  The paints may be diluted with water.  Paints containing a saponified wax as an emulsifying agent may be given a dull lustre after application, by polishing. Examples are given which specify as pigments, red iron oxide, titanium oxide, chromium oxide yellow iron hydroxide, and the azo dyestuff from diazotized 2-naphthylamine-1-sulphonic acid and b  naphthol (lithol red) and chalk.  Other azo dyestuffs from diazotized p-toluidine o-sulphonic acid and b  oxynaphthoic acid, from diazotized p-nitroaniline and b -naphthol and from diazotized p-toluidine sulphonic acid and acetoacetanilide may also be used. Chalk may be replaced by barium or calcium sulphates.
