Abstract: Apparatus 10 for moving a person into and out of a bath 12. The apparatus comprising a seat 48 mounted by pivotal linkages 38 and 62. The seat 48 can be raised using a ram 56. The linkages 38,62 are arranged such that when the seat 48 is raised beyond a particular height the seat 48 tilts rearwardly whereby to raise the legs of a person on the seat 48 to permit same to be pivotted over the side of a bath without the requirement of lifting the seat 48 far above the bath.

Abstract: A brushroll having a pulley driven spindle with an end assembly at each end rotatably mounting the spindle in a vacuum cleaner nozzle. On the pulley end of the spindle, a projecting pin is knurled at one end and inserted into the end of the spindle. An outboard portion of the pin is threaded. The knurling on the pin forms an abutment shoulder outboard of the end of the spindle. The drive pulley is threaded onto the threaded end of the pin until it contacts a bearing and presses it against the abutment shoulder, so as to prevent the pin from being jacked out of the spindle when the pulley is threaded onto the pin.

Abstract: A portable data collection device providing for optical character recognition. A housing defines an internal region and includes a user handle that allows a user to position the housing relative to an indicia carrying target. An imaging assembly includes a two dimensional imaging array supported within the internal region of the housing. The imaging assembly includes a capture circuit that generates a video signal representative of an image of a target zone. An optics assembly supported by the housing focuses an image of the target area onto the photosensor array. A character recognition processing circuit receives the video signal and categorizes the indicia on the target into a set of predefined characters. The character recognition processing circuit includes a discriminator for identifying a text region of the target and identifying individual character regions within the text region and a categorizer for identifying a character from a set of possible characters for an individual character region.

Abstract: A packaging machine and process for loading bags of a novel web of side connected bags are disclosed. The web is fed through a bagger section by a pair of grooved main transport belts and a pair of lip transport belts each disposed in the groove of the associated main belt to trap bag lips in the grooves. Adjustable belt spreaders space reaches of the transport belt as they move through a load station whereby to sequentially open the bags into rectangular configurations. A closure section in the form of a novel and improved heat sealer is releasably connectable to the bagger section. The sections are adjustable together between horizontal and vertical orientations. Processes of opening, closing and sealing side connected bags are also disclosed.

Abstract: An ion implanter includes an dosage control apparatus for measuring and controlling ion beam dosage applied to workpieces disposed in an implantation station of the implanter. The dosage control apparatus permits the direct calculation of a calibration function. The calibration function includes at least one calibration factor, called a K value. The K value is used by dosage control circuitry of the dosage control apparatus to convert from a measured ionized beam current, I.sup.f, as measured by a Faraday cage disposed in the implantation station, to a true or effective beam current, I.sup.T. The K value is determined from a relationship between the measured ionized beam current, I.sup.+, and a pressure, P, in the implantation station. The relationship between the effective beam current, I.sup.T, the measured ionized beam current, I.sup.f, and the implantation station pressure, P, will normally take the form of an exponential relationship, e.g., I.sup.T =I.sup.f [e.sup.-(KP) ].

Abstract: An oil skimmer of the endless belt type which is transportable as a unit is disclosed. The unit has an adjustment for adjusting the location of the axis of head pulley rotation and a floating tail pulley to assure accurate tracking of the belts on the pulleys and consistent and appropriate tension on the belt. The tail pulley features L-shaped spokes having legs that provide limited pulley-to-belt contact, minimizing oil transfer from the belt to the tail pulley, and also providing a mechanism for forcing oil against a descending belt reach to provide enhanced oil pick-up.

Abstract: An electrically conductive floor coating comprising a ferroalloy containing layer including particles of ferroalloy interspersed with a resinous binder.

Abstract: A sealing machine and process for sealing loaded bags of a novel web of side connected bags are disclosed. The web is fed through the sealer by a pair of grooved main transport belts. A holding belt is disposed in the groove of an associated main belt and extends into the groove of the other main belt as the belts move through the seal station. Processes of transporting and sealing side connected bags are also disclosed.

Abstract: Compositions herein increased creatine retention and/or glycogen storage in muscle. A composition comprises creatine or its derivative and a carbohydrate or its derivative. The carbohydrate is in an amount by weight which is greater than the amount of creatine. The amount of carbohydrate and the amount of creatine are effective for increasing creatine retention and/or glycogen storage in muscle. The compositions may be in the form of a pharmaceutical or a dietary supplement and are intended for use in the human or animal body. Other compositions comprise creatine or an active derivative together with insulin or an active derivative. The amount of creatine and the amount of insulin are effective for increasing creatine retention and/or glycogen storage in muscle. The compositions including creatine and insulin may further contain a carbohydrate or its derivative.

Abstract: An index selection tool helps reduce costs in time and memory in selecting an index configuration or set of indexes for use by a database server in accessing a database in accordance with a workload of queries. The index selection tool attempts to reduce the number of indexes to be considered, the number of index configurations to be enumerated, and the number of invocations of a query optimizer in selecting an index configuration for the workload.

Abstract: The invention provides a conversion means for converting a fixed type evaporative cooler (10) to a mobile type that includes a base with an opening (15), a sump (14) which can be of a size to suit one or more large coolers, means to accommodate a pump in the sump, wheels (24) firmly attached to the sump for support and mobility thereof, a filling station (22) for depositing water into the sump, and means to secure the sump to the base of a large cooler (12). The means to accommodate the pump includes a buoyant platform (16) thereby enabling the pump to remain in communication with fluid in the sump irrespective of the fluid level.
