Abstract: A proximity switching system comrising a plurality of self-propelled vehicles mounted in tandem on a track and carrying magnetic proximity switches for controlling the vehicle propulsion. Each vehicle has a first magnet mounted on the front end at a first position, a second magnet mounted on the back end at a second position, a first magnetic reed switch mounted on the front end at a position congruent with the second position on the back end, and a second magnetic reed switch mounted on the back end at a position congruent with the first position on the front end. A pair of electric rails are mounted next to the track. Each vehicle includes contacts for receiving voltages on the rails. A DC motor drives the vehicles on the track in one of two directions dependent on the polarity of the voltages, and for not driving the vehicles in response to the closure of the first switch when the voltage has one polarity and in response to the closure of the second switch when the voltage has an opposite polarity.

Abstract: A corticotomy osteotome is provided comprising an elongated body having a cutting end and an anvil end adapted for engagement with a mallet in advancing the cutting end, wherein the cutting end is of T-shaped cross-sectional form with the cross head of the T providing bearing surfaces for engaging outer surfaces of the bone cortex, and a rib extending perpendicularly and centrally of the bearing surfaces which protrudes from the bearing surfaces a distance approximately equivalent to the thickness of the bone cortex, the rib terminating in a tapered cutting edge extending perpendicularly to the bearing surfaces and being spaced inwardly from the leading edge of such bearing surfaces, and the upper surfaces of the body being smoothly rounded and tapered in the direction of the leading edge of the bearing surfaces permitting the leading edge to lift the periosteum from the bone cortex and support it in spaced relation to the cortex as the osteotome is advanced to cut the cortex, and the anvil end being engagabl

Abstract: A self-contained sewage waste disposal system including a housing structure and a toilet bowl adapted to receive human waste and fluid for diluting the waste, transporting the waste and rinsing the bowl. A removable filter cassette is in the housing in communication with the toilet bowl. The bowl is flushed and the contents are dumped into the filter cassette and the bowl is subsequently refilled. Filters in the cassette separate the coarse and fine particles of solid material from the fluid received from the bowl. The solid material is stored in the cassette in a compact manner for subsequent disposal upon removal of the cassette. Fine filtering and decoloring is accomplished by a carbon canister. A reservoir is provided for storage of fluid after removal of solid material therefrom in the cassette.

Abstract: A method and apparatus for transferring containers having projections horizontally extending from a pair of opposite sides thereof between a vertically moving tray and a pair of generally horizontally disposed transfer tracks which can be moved between (a) an inner position in vertical alignment with the container projections for transferring a container to or from an upwardly or downwardly moving tray, respectively, and (b) an outer position in which the transfer tracks are displaced outwardly and laterally of the container projections, to allow a container on an upwardly or downwardly moving tray to pass unimpeded past the transfer tracks when transfer thereof from the tray is not desired.

Abstract: Method and apparatus for random segment imprinting of alphanumerical designations and other symbols on cartons, cases, and the like. The imprinter includes a control logic module, a rotating print cylinder, and an ink cartridge. It permits rapid automatic substitution of designations without interrupting the printing process.
