A carpenter's pencil sharpener is designed for cutting a point on a carpenter's pencil that defines a longitudinal axis and has a maximum width or dimension (MD) perpendicular to the longitudinal axis. The sharpener has a contouring portion defining a rotational axis, a pencil point contour surface and a blade. The sharpener also has a centering portion at least rotationally fixed to the contouring portion. The centering portion has a non-rotating, cylindrical, inner surface and an outer end defining an aperture for receiving the carpenter's pencil. The cylindrical surface has an inner diameter (ID) dimensioned to fit the maximum dimension (MD) of the carpenter's pencil, and is large enough to permit rotation of the carpenter's pencil within the cylindrical surface. The centering portion also has a length (L) generally parallel to the rotational axis and measured from the contouring portion to the outer end for maintaining the carpenter's pencil parallel to the axis. With this configuration, radial motion of the carpenter's pencil relative to the rotational axis is limited when the carpenter's pencil is rotated within the inner surface.

A system for treating a patient's heart which comprises a means to form channels in the heart wall and a means to deliver a therapeutic or diagnostic agent into the channels. Additionally, the system may comprise a means to retain the agent within the channels for a useful period of time. The system may be configured to be introduced percutaneously or intraoperatively. The system generally comprises an elongated, flexible lasing transmission means having a laser radiation emitting means and an delivery lumen opening at the distal end. Practice of the invention comprises forming channels in the heart wall and delivering a therapeutic or diagnostic agent into the channel. Gene therapy agents of this invention comprise vectors for transferring genetic information to the heart tissue in vivo or harvested cells which have been genetically engineered in vitro. Additionally, the invention may comprise retaining the agent within the channels, for example, by incorporating the agent in a viscous carrier.

An accessory system for a ductwork cleaning machine that utilizes a vacuum hose having a rotating cleaning brush the vacuum and the power for the rotating brush being supplied from a remote power unit with a rotating drive cable being located within the vacuum hose. The accessories permit more efficient operation of the ductwork cleaning system. The first accessory is an improved nozzle for mounting the rotating brush which permits large vacuum openings without the risk of an operator becoming entangled with the rotating cable. A second accessory prevents the cable from withdrawing within the vacuum hose when the hose is disconnected from the power unit. The third to accessory is attached to the power unit and guides the guide cable into place as the vacuum hose is attached to the power unit.

The present invention relates generally to the field of sex determination of animals. Provided are methods and agents to manipulate sex determination, particularly in avian animals such as chickens, through a male chromosome-linked testis (sex) regulatory gene. Expression or activity of the DMRT1 gene or protein is modulated to produce animals with displaying a phenotype sex that differs from their genotype.

A camera has a body and an electronic capture unit mounted in the body. The electronic capture unit selectively captures and stores a scene image as a representational electronic image having a first array of pixels. A control system is mounted in the body. The control system provides a remapped electronic image having a second array of pixels. A memory unit is disposed in the body. The memory unit stores a data-set defining an non-uniform mapping between a plurality of primary input coordinates mappable on said first array of pixels and plurality of primary output coordinates mappable on said second array of pixels. The control system uses the data-set to remap the pixels of the input electronic image to provide the remapped electronic image.
