  • Patent number: 5667082
    Abstract: A ball caddy includes a housing with dividers forming compartments within the housing. The compartments retain various size sports balls in a vertical arrangement The dividers have two hinged segments which are independently adjustably mounted within the housing to vary the size of each of the compartments. Each compartment also has an orifice formed at a lower portion thereof and a ball release device which has a retainer normally preventing dispensing of the balls. The handle attached to the ball release allows pivoting of the ball release to provide for dispensing of the balls through the orifice.

  • Patent number: 5652421
    Abstract: An electronic gift certificate dispenser device for printing and dispensing a gift certificate purchased by a credit card. A consumer approaches the device and inserts a credit card into a magnetic card reader. The consumer chooses a retailer from a menu of participating retailers and enters the gift certificate value. The machine automatically verifies the credit card, causes the account to be debited and prints the gift certificate. A plurality of gift certificate dispensing devices can be connected in a network under the control of a central processing unit. Information regarding gift certificate purchases is transferred from the devices to the central processing unit to be collated and billed to credit card accounts. The central processing unit also informs merchants of the purchase of gift certificates that will be redeemed at their stores.

  • Patent number: 5404436
    Abstract: The invention method and apparatus employs font metrics data related to font bitmaps for characters of a desired font. Position offsets of pieces in composite characters are read from the font metrics data and are converted to the appropriate pixel offset to adjust the bitmaps of subject compressed font characters. The adjusted bitmaps of the different pieces of a subject composite character are combined to form a working bitmap which represents each piece of the composite character in full size in the subject font. Screen display of composite characters decompressed to full-size is supported by the formed working bitmaps.

  • Patent number: 4672035
    Abstract: The regeneration of plants from cotton callus (Gossypium hirsutum L. cv Coker 310) is described. Somatic proembryoids developed spontaneously after two years in culture on a modified Linsmaier and Skoog medium. The percentage of calli forming proembryoids was increased to about 30% by prolonged culture without NAA and kinetin. Development of proembryoids was enhanced by transferring proembryoids to media lacking NH.sub.4 NO.sub.3 but containing double the standard KNO.sub.3 concentration and gibberellic acid. Root initiation and growth was promoted by lowering the glucose concentration to 5 g/l.

  • Patent number: 4355786
    Abstract: Apparatus adapting a guide device for use with a hand-holdable cutting torch. The guide device has an articulated arm whose free end is movable in a planar path defined by a stationary pattern template which the arm engages. The torch is of a type having a barrel, a handle carried on the barrel, an elongated nozzle, and an angled connection between the barrel and nozzle. The adapting apparatus includes a bushing for releasably clamping the torch nozzle, and a bushing-support plate carried on the free end of the arm in the guide device. The bushing, with the torch nozzle clamped therein, is mounted on the support plate for rotation relative thereto about the axis of the torch nozzle, where this axis is disposed substantially normal to the plane of arm movement. The apparatus enables the user to guide the movement of the arm along the template path by manipulating the torch handle.
