Abstract: 393,256. Cash registers &c. KRUPP AKT.-GES., F., Essen, Germany. Aug. 28, 1931, No. 24237. Convention date, Oct. 9, 1930. Void [Published under Sect. 91 of the Acts]. [Class 106 (i).] In a machine provided with a total lever capable of a position in which it controls the machine for non-add operations, the lever is automatically returned from such a setting to the adding position at the end of the operation of the machine. If the machine possesses a " balance " lever to control the operations of the machine for obtaining a customer's new balance, the automatic restoration does not occur unless the latter lever is in the balancetaking position. As shown in the Figure, the total lever 5 is in its uppermost position for controlling the machine to record, but not register, an item and in this position a pin 13 on the lever is in engagement with an arm 14 loose on the shaft 11 and pivotally connected with a pitman 16 suspended by a lever 17. Pivoted at 18 is a lever 29 spring-connected at 32 with the lever 17 and provided with a lug 29c for engagement by a cam 33 rotated by the main shaft. Near the end of each cycle therefore the lever 29 is rocked counterclockwise and through a roller 19a carried by an arm 19 forces the pitman 16 to the right and returns the lever 5 to its adding position. The arm 19 is movable along the shaft 22 by means of a cam groove drum rotatable by the " balance " lever so that if the latter is in adding position the roller 19a is withdrawn and the restoring mechanism is consequently disabled. The lever 5 can only be shifted to its non-registering position after removing a locking bolt 36; that does not however prevent the return movement.

Filed: 1970-08-20
Abstract: 1323893 Bearings; lubrication LITTON INDUSTRIES Inc 20 Aug 1970 [21 Aug 1969] 40061/70 Heading F2A A lubrication system for a bearing and spindle assembly is provided with a device which determines the flow of lubricant from the bearings by passing the lubricant into a store in the lubricant return line and monitoring the level of lubricant in the store and shuts down the operation of the assembly in the absence of sufficient lubricant. Lubricant is pumped from a sump to the bearings 8, 9 of a machine via conduits 35, 36, 37, and returns from the bearings via a conduit 43 to a vessel 44 located in the sump 40 with its bottom above the normal oil level in the sump. The vessel is provided with baffles 48 and a cover 47 so as to form an inner chamber 50 and an outer chamber 51. As lubricant flows into the vessel from the bearings the pressure in the inner chamber increases until it is sufficient to operate a pressure switch 4PS which is located in the control circuit of a motor which drives the spindle. The circuit (Fig. 3, not shown) is arranged so as to permit operation of the motor only when there is a predetermined pressure in the chamber 50. Lubricant flows out of the vessel 44 into the sump either through ports 53 in its base, or through an overflow 54. The size and number of the ports determines the rate of increase of pressure in the inner chamber. Lubricant which leaks past sealing rings 21, 22, 23 is returned directly to the sump via a conduit 57. In an alternative embodiment, (Fig. 2, not shown), the sump and vessel to which lubricant returns are located in the bearing housing itself. The bearings are mounted in axially adjustable retaining rings, and positioned longitudinally in the housing 6 by adjusting nuts 18. The nuts 18 threadably engage clamping rings 20 which are secured to the sides of the housing. A thrust collar 24 is secured to the spindle by means of a screw 25 which permits axial adjustment of the collar. The collar bears against the side face of the bearing 9 and a shoulder of the spindle bears against the side of the bearing 8.

Title: Encapsulated emulsions and processes for their preparation
IPC: B01J13/10
Filed: 1959-11-26
Abstract: Particles of a (primary) hydrophilic liquid-in-oil emulsion containing an anti-inversion agent in the oil phase are encapsulated by dispersing the said primary emulsion to form a secondary emulsion in an aqueous dispersion of at least two coacervating colloids at least one of which is a hydrophilic colloid and at least one of which is a linear macromolecular synthetic polymer and causing a coacervate of the polymers to deposit about the particles of the primary emulsion and, if desired, subsequently drying and/or hardening the capsules.  The primary emulsion may contain conventional emulsifying agents e.g. esters of polyhydric alcohols, sorbitan derivatives, and sorbitan polyoxyethylene derivatives and advantageously contains a thickening agent, e.g. acacia, methyl cellulose, magnesium aluminium silicate, glycium and syrups in the hydrophilic liquid phase.  As anti-inversion agents there are mentioned surface-active agents (preferably non-ionic), and conventional oil-gelling and oil-thickening agents, e.g. waxes, solid fats and sterols.  Suitable hydrophilic colloids are naturally occurring gelable and nongelable hydrophilic colloids and derivatives thereof, e.g. gelatine, agar, albumen, deacetylated chitins, pectins, acacia, starch and fibrinogen.  Suitable linear macromolecular synthetic polymers are those whose structure comprises both lipophilic units and hydrophilic units, e.g. styrene-maleic amide copolymers, sulphonated polystyrenes, carbohydrate acetate phthalates and (preferably) hydrolysed styrenemaleic anhydride copolymers of general formula [-R-R1-]n, wherein R represents lipophilic units of which more than 70% are styrene residues and R1 represents hydrophilic units of which more than 50% are maleic acid residues. Coacervation may be induced by alteration of the pH of the polymer dispersion or by dilution thereof with water.  Either or both phases of the primary emulsion may contain dissolved or suspended "active" ingredients which render the encapsulated products useful, e.g. as sustained release fertilizers, plant growth regulants, pesticides, bactericides, food additives, cosmetic ingredients, vitamin preparations and pharmaceutical materials. Specific examples include: (a) aqueous chloral hydrate-in-mineral oil emulsion in gelatine and styrene-maleic acid copolymer; (b) glycerine suspension of rotenone in mineral oil in serum albumin and styrene-maleic amide copolymer and (c) aqueous urea solution-in-peanut oil in gelatine and styrene-maleic acid copolymer.  Specification 751,600 is referred to.
