Abstract: The present invention relates to synthetic, fatty phosphoric acid esters which, when neutralized with a neutralizing agent, is revealed as a new surface active agent, having emollient characteristics. Formulations are presented which demonstrate a method for using the disclosed surface active agent to prepare stable oil-in-water and water-in-oil emulsions of varying polarity and viscosity for use in a variety of dermatological applications, and/or wherever emulsions according to the present invention may be used.
Abstract: A method and apparatus for fusing a pair of optical fibers together using an intense beam of electromagnetic radiation directed against the aligned ends of the optical fibers. The intense beam is of a power sufficient to fuse the fibers together, and is applied for a time sufficient to effect joining of the fibers. Preferably, the beam is of a sufficiently high intensity to create a plasma which increases the amount of optimal power absorbed by the fiber ends.
Abstract: A cation exchanger or a chelating agent having at least structural units represented by the following formula (I), the structural units being derived from a crosslinkable monomer containing an unsaturated hydrocarbon group:
wherein A represents a C3-C8 alkylene group or a C4-C9 alkoxymethylene group; L represents SO3−X+, where X+ is a counter ion coordinated with the SO3− group, or a chelate-forming functional group; and the benzene ring may be substituted with an alkyl group or a halogen atom.
Abstract: The invention is a unit for pneumatically controlling the position of a workpiece relative to a predetermined workpiece configuration, comprising an enclosure, a minimum of one measuring nozzle for a gaseous pressure medium, which measuring nozzle is located in a contact surface a workpiece fixture. A pressure supply line is connected to the measuring nozzle via pressure lines. Separate adjoining modular enclosure components are detachably connected to one another and each is fitted with a connection leading to measuring nozzle. A first enclosure end cover can be connected to a pressure supply unit and a second enclosure end cover is located at a distance from the first enclosure end cover. The first enclosure end cover, the modular enclosure components that adjoin the first enclosure end cover, and the second enclosure end cover that adjoins the modular enclosure components form the overall enclosure 68.
Abstract: An apparatus for supplying sealing film for a blister band to a splicing station (10) includes a stepwise rotating drum (8) on which reel carriers (7) are mounted for receiving reels (6,6s,6a) of films (1,1s,1a). A pair of holding-driving rollers (16,17) are located close to each of carriers (7) to hold the film (1a) and to feed the film to the splicing device (10). The rollers (16,17) are operated by a retractable shaft (32), which engages the pair of rollers (16,17) situated in the region of the splicing device (10). A plate (5) keeps apart the film (1a) unrolled from a replacement reel (6a) from the film (1s) coming from a running out reel (6s). The plate (5) can be shifted crosswise with respect to the film unrolling direction, so as to allow the in-wait-state film (6a) to move to the unrolling position (S) after the splicing.

Abstract: A valve has a valve body, a valve sheet formed in the valve body which contacts the valve sheet in an axial direction, to thereby open and close the valve sheet with a knurling portion and a screwing action. A handle is combined with a handle combination unit formed in an upper portion of the valve body, so that a valve rod can ascend and descend. An oil storage chamber is located between the knurling portion and the screw, to maintain the ascending and descending of the valve rod. The angular slope in the screw thread is formed so as open and close the valve by 90° rotation of the valve rod. A stem contacts the valve sheet, the stem having a conical end portion, which is received by the valve sheet. The handle is flexibly manipulated to simply and swiftly control flow and entrance/exit of fluid. The valve can be used semi-perpetually since wear of the valve sheet is prevented, providing excellent general purpose usability.
Abstract: An ultrasonic surgical blade has a blade body with a smooth continuous cutting edge and a shank connected at one end to the blade body and operatively connectable at an opposite end to a source of ultrasonic vibrations. The shank is provided with an axially extending bore for the conveyance of cooling fluid to the cutting edge, while the blade body is provided with an axially extending through-slot communicating at one end with the bore. The blade body is preferably provided at an end opposite the shank with a recess communicating, with the bore for distributing fluid from the slot towards the cutting edge. The recess preferably has a configuration which parallels at least a portion of the cutting edge. Where the cutting edge is circular and the blade body has a planar surface between the fluid distribution guide surface and the cutting edge, for instance, the recess has a fluid distribution surface inclined with respect to the planar blade surface and extending along a circular arc.

Abstract: In a conveyor including an endless belt (3) that features equispaced recesses made on an outer surface of the belt, the recesses can be set in communication with a vacuum source when they are moving along an upper run of the conveyor, so as to grip a base (50a) of a container located thereon. A pad (15) is provided for each recess and is hinged to the belt right behind the respective recess for receiving in abutment and pushing a rear wall (50b) of the container. A connecting rod (8) is pivoted at the top to the pad and at the bottom to the belt.

Abstract: The present invention relates to a device for driving a sprocket of a bicycle, which enables a rider to easily rotate both pedals even with little force when both cranks of the pedal are vertically positioned. According to the present invention, when a crank (11) gets to be vertically positioned by rotating the pedals (11a), a guide pin (21) projected from a rotating plate (20) draws a tensile spring (41) from the guide groove (31) and thereby the rotating plate (20) gets to be elastically rotated so the crank (11) can go off the vertical position rapidly. Accordingly, the rider can easily rotate the pedals, and at the same time, the force of restitution of the drawn tension spring (41) can help the sprocket (10) be rotated. Consequently, the accumulated force of the tensile spring (41) accelerates the rotation of the sprocket (10) to enable the crank (11) to go off the vertical position effectively, which in turn enables the rider to drive the bicycle with ease.
Abstract: In a device for filling a blister band with products, a hopper (3) holds the products (2) in bulk and has a open bottom where taking over rollers (17) rotate to slightly push the products upwards, contrasting the products weight and causing reciprocal detachment of the products. The taking over rollers (17) define openings, and one product (2) at a time passes suitably oriented through each opening and towards a conveyor including channels (4) having inlets (4a) situated directly under the openings. A delivering cylinder (7) is connected to the channels (4) and transfers the products (2) to the blisters (5a) of the band 5.

Abstract: According to the invention, a pouring spout for mounting on a container's neck can be configured as a spout placed in the container's neck, which spout goes on the inside of the neck so that possible drops of liquid will be collected inside the neck. Drops of liquid running on the outside of the container are hereby avoided and at the same time it is achieved that the container can pour in all directions since the edge of the pouring spout extends uniformly around the container's neck.

Abstract: A device for feeding tablets in a blister packaging machine includes a vibrating container containing a mass of tablets. The vibrating container features a bottom wall, one portion of which includes tablet feeding channels, communicating with related slots made in the bottom wall. The slots communicate with the conveying means, which feed the tablets along a predetermined feeding path and release the tablets into respective blisters of a blister band. The blister band moves in a determined direction inside the packaging machine. The conveying means include a plate with a plurality of grooves, arranged one beside another and a covering element. The covering element is coupled with said plate, so as to move with respect thereto and includes transversal wings, each of which is situated inside a respective groove of the plate, so as to define a respective channel for conveying said tablets.
