A novel retrofit process for converting the hydraulic lathe of an existing pulp-grinding machine into the new electric one is described. This process includes utilization of the pre-existing hydraulic cylinder as a supporting housing and shield for a major portion of the drive assembly for the electric lathe. In the preferred "retrofit" embodiment, the drive for the lathe comprises a ball-screw assembly housed inside the cylinder, after the cylinder has first been evacuated. This drive assembly ...

A shotshell cartridge adapter is disclosed that enables safe firing of subcaliber rim-fire shot cartridges in conventional shotguns. In the preferred embodiment, the invention comprises an outer hull shaped like a standard shotgun shell; an adapter tube fixed within the hull; and a cylindrical firing pin mechanism removably housed within the lower end of the tube. This firing pin mechanism has a recessed piston-shaped firing pin with a chisel-pointed protrusion that strikes a shot cartridge load...

An alarm system is disclosed for warning personnel at a loading dock that a trailer being loaded has crept away from the dock. In a preferred embodiment, the alarm comprises a box-like housing that can be bolted onto the dock; a clamp that is magnetically held against the outside of the housing and which can be removed for quick attachment to a nearby trailer; and, a spring-loaded cord that is spool fed from inside the housing and connected to the clamp. After the clamp has been attached to the ...

Adjustable modules are disclosed for building final products of various sizes from a single-sized, mass-produced unit. In the preferred embodiment, each module is made of mass-produced, left-hand and right-hand sections that are joinable at oppositely facing, abuttable ends by any suitable means--here, dowels that fit into aligned channel halves in the complemental faces of the two sections. By utilizing the split-section aspect, the overall size of the final product, e.g., a door, can be reduce...

A light is provided which includes a first, forwardly concave reflector member, a first, forward lamp spaced ahead of the reflector member, and a second rearwardly concave reflector member spaced forward of the lamp. The rear reflector member has a generally parabolic surface and the forward member has a generally arcuate surface. When the lamp is activated, its rays generally travel forward, are reflected off the second reflector member rearward onto the first reflector member, and thence forwa...

A method and apparatus for making golf ball molds is disclosed. The molds are made by placing a smooth, hemispherical metal cup on top of a dimpled, hemispherical master mold, which is the upper end of a bullet-shaped mounting post. The post is fixed in an upright position to the lower half of a hydraulic press. Above the post is a vertically movable upper press half with a urethane insert. The insert has a smooth hemispherical recess or cavity that is designed in size and shape to blanket the t...

A colo-rectal evacuator is disclosed for mechanically removing waste material through a patient's rectum. The evacuator includes a rectal tube with a distal nozzle end that is designed to be inserted into the patient's anal canal; an adjacent inflatable bladder that is adapted to abut feces inside the canal and remove them when the tube is pulled by a trained professional; a lower balloon that is adapted to burst and provide lubrication to ease the removal; and a collecting bag that surrounds th...

A fiber-optic light system is disclosed for providing highly concentrated, cool light to projectors and reproducer sound heads, such as the type found in the projection room of a movie theater. The light beams onto a film to project the film's images onto a screen and release its soundtrack. In the preferred embodiment, a system is disclosed for providing fiber-optic light to a plurality of projector-and-reproducer sound sets from a single light source. A plurality of fiber-optic cables are conn...

An apparatus for randomly selecting combinations of numbers for lottery-type games of chance. In the preferred embodiment, the invention comprises an adaptor hood which sits on a downsized, bingo-ball blower. The hood includes a lower access hole to receive lightweight numbered balls from an underlying blower chamber in which the balls are blown about; a spring-biased selector arm that normally straddles and blocks the hole, but which can be manually pivoted to allow a ball to pop up the hole an...

An improved vacuum distillation system is disclosed for purifying contaminated liquids, such as seawater, brackish water and chemical effluents. In the preferred embodiment, the system includes a vertical separation chamber in which contaminated liquid (e.g., impure water) is boiled and evaporated at a low temperature due to a low pressure created by a vacuum pump; a stack of fan-shaped baffles in the top of the separation chamber that provide a tortuous path for the "distillate vapor", wherein ...
