Title: Improvements in milking machine
IPC: A01J5/04
Filed: 1920-07-02
Abstract: 146,295. Burton Page Co., (Assignees of Shippert, W. A.). May 12, 1916, [Convention date]. Cow-milkers.-In a device for milking co½-s, the milk-receptacle supports, by wires 2 with hooks 3 and an adjustable clamp 6, a plate 1 carrying a vessel 9, that can move vertically within a vertical ring 8 also carried by the plate 1. The lower end of the vessel 9 is flanged and is provided with a rubber gasket 13. A tube 17 connected by pipes 18 with the teats of the milking-appliance passes through the plate 1 and carries at its upper end a baffle-plate 21 having a downwardly-turned edge. A pipe 20 which opens into the vessel 9 under the plate is connected through a tube 25, Fig. 3, with an airpump. The tube 25 contains an outwardy-opening valve 26 and is provided at each side of this valve with a number of holes 30, 31 which are normally covered by an elastic jacket 32 secured on the pipe by bands 33. On the suction stroke of the pump, the valve 26 drops, maintaining a vessel 9, the gasket 13 maintaining an air-tight connexion between the vessel and the plate 1. The milk flows from the teats through the pipes 18 and is discharged from the upper end of the tube 17 into the vessel 9. On the reverse stroke of the pump, the valve 26 drops, maintaining a reduced pressure in the vessel 9 until the pressure of the air at the outer side of the valve has been raised sufficiently to force back the jacket 32 on the pipe 25, thus permitting air to reach the lower side of the valve through the holes 30. 31. The increase in pressure thus developed in the vessel 9 lifts it from its seat on the plate 1 and permits the milk in the vessel to escape into the main receptacle. The vessel 9 is preferably made of glass, but may be made of metal or other material.

Abstract: 490,479. Making boxes; feeding sheets. BERGSTEIN, S. July 8, 1937, No. 19031. Convention date, March 9. [Class 18] [Also in Group XVI] The blank shown in Fig. 11 is made up into a tray in the collapsed state in a machine which folds under the triangular flaps f, f<1>, turns the sides b, c with their folded flaps and also tabs g, g<1> on to the top of the blank, and, after glue has been applied to the flaps or the tabs, folds the ends d, e on to the top of the blank so that the tabs overlie the folded-back flaps. In a machine for performing these operations, the topmost blank of a pile a, Fig. 20, is fed on to two conveyer belts running in channels 12 by a roller 10 with a friction pad 11. The latter has a grooved surface which is keyed up by a buffing wheel 10a driven by a separate motor, the buffing wheel being cleaned by a scraper 11h. Rollers 11c, carried by spring-pressed arms 11a adjustable in slots 11f, press on the various flaps of the topmost blank and prevent that blank from fouling the one underneath. The blanks are pushed through the machine by pins 15, Fig. 16, on the conveyer chains and this is assisted by two further chains with friction pads which engage the centre parts of both faces of the blank. The upper one of these additional chains runs in a series of inverted channels pressed downwards by springs and carried by an intermediate, longitudinal frame in the machine. The leading flaps f are depressed by rollers 33, 34 adjustably mounted on their shafts and of which the roller 33 is ribbed and roller 34 is provided with corresponding pockets ; and the flaps are folded back as they ride past plates 37 and pressure bars 38. The trailing flaps f<1> are subsequently depressed by rollers 39, 41, Fig. 17, similar to the rollers 33, 34, the flaps are held down by a pin 55 which runs along with the blank on a chain 52, and they are folded back by a sweep 60 rotating about a vertical axis. A finger 61 supports the flap adjacent the fold line and both sweep and finger ride with the blank over an inclined supporting bar 63. An horizontal chain 52 and a vertically swinging sweep 60 may be employed. A pair of twist belts turns the sides b, c and tabs g, g<1> over on to the upper surface of the blank which is then delivered on to feed chains running at right-angles to the main conveyer. Here the gluing and final folding operations are carried out by any usual apparatus.

Title: Improvements in or relating to synthetic lubricating oil
IPC: C10M141/10
Filed: 1951-08-14
Abstract: A mineral lubricating oil fraction, which has been solvent-extracted and hydrogenated, is contacted with air or oxygen at 200-400 DEG F. so that a product having a saponification number of 20-70 is obtained, this product is neutralized with a neutralizing agent or agents comprising alcohols, organic amines of ammonia, until the neutralization number or the product is not greater than 50 per cent. of its original value, the neutralized product is vacuum-distilled to remove low-boiling oxidation products and/or volatile neutralizing agents, and an oxidation inhibiting compound is added to the distilled product in an amount sufficient to prevent absorption of oxygen, when the product is in contact with oxygen at 350 DEG F., at a rate greater than 1 per cent. by weight per hour.  The composition thus obtained is suitable for use as the lubricant in automobile crankcases.  The solvent employed in the solvent extraction may be phenol, cresols, nitrobenzene or furfural and the lubricating oil fraction may also be dewaxed.  The hydrogenation may be conducted in the presence of a hydrogenation catalyst, such as nickel, nickel on kieselguhr, platinum, palladium, nickel and tungsten sulphides, cobalt molybdate on alumina, or molybdenum on alumina.  The degrees of hydrogenation is preferably such that the sulphur content of the oil is reduced to 0.03 per cent. by weight or less, and the colour of the oil is improved to 18 Tag-Robinson or higher.  Contact of air or oxygen with the oil may be affected by passing the air or oxygen through a diffuser placed in the oil contained in a tall column reactor.  As catalysts to initiate oxidation, organic peroxides such as benzoyl peroxide are preferred to metallic catalysts such as manganese naphthenate or calcium salts. Alcohols, which may be employed to neutralize the free acid by esterification, are saturated aliphatic alcohols containing 2-20 carbon atoms in the molecule, particularly butyl alcohol.  If desired, the oxidized oil may be partially neutralized with alcohol and the neutralization completed with a metallic base, for example an oxide or hydroxide of an alkaline earth metal.  Thus, a mixture of calcium oxide and calcium hydroxide may be employed, but barium oxide with or without barium hydroxide, and magnesium oxide with or without magnesium hydroxide may be used.  Oxidation inhibiting compounds mentioned are the reaction product of alphapinene and phosphorus pentasulphide, alkaline earth metal salts of alkylated phenol sulphides and their reaction products with sulphur and sulphides of phosphorus, also phenyl alphanaphylamine and 2, 6-di-tert-butyl-4-methylphenol. Further substances may be added to the final composition, for example viscosity index improvers, pour point depressants, metal deactivators, detergents, thickeners and soaps.
