Abstract: A lightweight handle accessory particularly adapted to be mounted on the generally straight shaft of a work tool or other working or sporting implements, having a clamping portion partially surrounding the shaft or other surface to be gripped which cooperates with a flexible fastening means of variable diameter to frictionally engage the shaft and fixedly mount the handle accessory. A handle is mounted near the outward end of opposing lever arms to enable the operator to grip the assembly. The underside of the gripping portion is serrated and divided into mirror images with a central slot which allows flexing of the gripping portion to adapt to a wide variety of mounting surface sizes and tapers. The flexible fastening means may be easily disengaged from one shaft or implement and remounted on another differently sized shaft or implement without loss of holding power.

Abstract: The subject invention comprises systems for the automatic removal of waste hydrocarbons from water. Waste water enters a primary vessel through a baffled inlet chamber, allowing solids to fall to the bottom of a main collection chamber as the waste hydrocarbons float upwardly on the water in this chamber. The separated water flows out of the chamber into the sewer system or other discharge areas. When the oil level in the primary vessel reaches a predetermined level, a control system allows water to enter the bottom of the main collection chamber, closes off the normally open water discharge outlet. The entering water forces the waste hydrocarbon level upwardly, until gravity forces the waste hydrocarbons out the waste discharge outlet into a storage vessel. When the waste is completely discharged, normal waste waste flow-through is resumed. Upon filling the storage vessel with waste hydrocarbons, all operations are suspended until the stored hydrocarbons are pumped out.

A drive means is provided for raising the lower shelf individually until the receptacles it supports contact the bottom of the upper shelf, whereupon both shelves move upwardly in tandem toward the fixed plate, the receptacles on the upper shelf being stoppered against the fixed plate and the receptacles on the lower shelf being stoppered against the bottom of the upper plate.

Abstract: A shell freezer for the freezing of liquids in a container in a uniform layer on the interior walls of the container having belts rotating over rollers within a bath; rods are secured over the belts to act as stops for cylindrical containers placed on the belts, thereby causing the rotation of the containers. Underneath the rotating belt is a supportive platen which is covered with a fabric to allow smooth rotation of the belt while supporting a flask full of liquid. The bath may be tilted to a desired angle to allow more liquid to be frozen within a container. A novel heat exchanger cools the thermal transfer fluid which is circulated over the belts and back to the heat exchanger, to allow a minimum of such fluid in use.

Abstract: A new and improved corrosion resistant condenser is provided, adapted for use with a freeze drying system for dehydration of materials with relatively high concentrations of acids or bases. The condenser includes unique heat transfer means for uniform transfer of heat flow between the outer surface of the condenser and a corrosion resistant condensing trap disposed inside the condenser, which condensing trap may be readily removed from the system and immediately replaced in preparation for another freeze drying procedure.

Abstract: A grease separating system includes four successive chambers. The heated, emulsified grease is passed through a solids retention box into an inlet chamber where cool water is sprayed onto the emulsified grease. This mixture is passed through a connecting chamber, and then over baffles at the entrance of a collection chamber. The grease having been separated from its emulsified state rises to the top of the mixture in the collection chamber, and the water passes into a discharge chamber and in to the connected sewer system. After successive operations, the floated grease is sensed when it reaches a predetermined level, and an alarm is sounded to indicate that the accumulated grease should be removed.

Abstract: An improved low cost screen printing apparatus for printing on both flat and curvilinear objects. Two vertically aligned shafts support the printing head and, by following the pivotal motion of an arm, raise and lower the printing head relative to the object being printed with a straight vertical displacement, resulting from the controlled movement of the upper shaft cooperating with arcuate channels formed in the end supports. The squeegee assembly operates in a timed relationship with the raising and lowering of the screen head to alternately lower the squeegee and raise the flood bar for forcing ink through the screen in the print cycle and raise the squeegee and lower the flood bar to flood the screen on the return cycle. When the screen is in the raised position, the squeegee assembly and screen frame are selectively connectable to a reciprocating carriage, for printing either curvilinear or flat objects.

Abstract: A method and apparatus for effecting an efficient heat transfer between a shelf and a tray of a freeze drying apparatus. A unique method comprising the steps of placing two halves of the shelf on a bowed jig and welding together forms a hollow shelf having a substantially flat heat transfer surface on which a tray containing materials to be freeze dried may be placed. Throughout the shelf interior circulates a heat transfer fluid. The tray and the freeze drying chamber have mating hold-down rails which bias the tray against the shelf surface to effect superior heat transfer.
