Abstract: An actuator for a press comprises a piston disposed through a small bore diameter high speed actuating cylinder, having a piston head disposed within the actuating cylinder and another piston head disposed within a larger bore diameter hydraulic clamping cylinder to apply the required clamping force to the press.
Abstract: A process for manufacturing a non-toxic environmentally friendly target comprising petroleum pitch and filler includes the steps of pre-heating the petroleum pitch binder to at least 450° F., mixing the petroleum pitch binder with limestone filler so that toxins in the petroleum pitch binder are neutralized, and setting the mixture into target molds. The petroleum pitch binder and filler are preferably mixed for at least 2 hours at a temperature of at least 400° F.
Abstract: A system for redistributing a multiple input audio/video and data signals having a redistributing device equipped to receive signals in a multiple formats and redistribute a selected signal to a user's premises over conductors, preferably existing twisted-pair telephone wire. The redistributing device is in interactive communication with a communications interface located in the user's premises which receives user-input control signals and contains switching circuitry which routes the selected signal to the user's premises where it is received by the receiving unit such as a television receiver. A single redistributing device services an entire multi-user network from a common distribution point, and services multiple users independently. The system of the invention does not interfere with normal use of the telephone network, so users can interactively access services provided by the system and use the telephone at the same time.
Abstract: An apparatus and process for installation for supplying superior closeup images of an individuals face and provide a height measurement device for witnesses for the purpose of identification with the steps of; utilizing sunlight to illuminate a subject's face for better exposure, always being directed towards the path of an individual arriving or exiting a building or structure, placed at eye level to avoid physical obstructions and a multiple axis mounting system to enable fine position adjustments. Preferred embodiments include a machine that is installed on a door frame or wall, facing into a building structure no less than ninety degrees from an existing outdoor light source, facing towards the suspects path of exit, a machine that is covert in it's operation and provides a height scale for witnesses to identify a subjects height as they leave through the door.
Abstract: A modular mounting system which allows a circuit board to be removed, inserted or replaced through the front of the mounting frame without deactivating power to the equipment, and in the preferred embodiment without detaching any external cables. Connections for external equipment are disposed along the rear edge of the circuit board, and a row of contacts for the internal connections is provided along the bottom edge of the circuit board. The system of the invention provides a releasable connector which retracts the connector pins into a housing when a circuit board is inserted or removed, thus eliminating the possibility of a contact on the circuit board touching a live connector pin. In the preferred embodiment the external connections are made through adaptors that plug into external cable connectors provided on a connector plate detachably affixed to the rear of the mounting frame.

Abstract: A work support which assists in the inversion of a large workpiece has a supporting frame and a top frame. The top frame is provided with an intermediate hinge and an end hinge along at least one end, so as to be collapsible, and the leg of the supporting frame is hinged along the opposite end. The workpiece can be moved to one side of the intermediate hinge and the top frame can be collapsed, lowering the centre of gravity of the workpiece and standing it partially on edge. One or two workers can then easily shift the workpiece over to the other side of the top frame. When the top frame is raised back to a horizontal position the work surface is in an inverted condition, exposing unfinished surfaces for finishing. In the preferred embodiment the top frame is provided with a flexible membrane overlaying the intermediate hinge. When the top frame is collapsed the membrane curls upwardly and forms a cushion which supports the edge of the workpiece, and thus assists in the inversion process.
Abstract: A utility knife having a quick release feature, whereby a resilient blade engaging member biased to the locked position engages an opening in the blade, and when the blade engaging member is pushed against the end of a guide slot it automatically releases from the blade allowing the blade to be removed from the knife handle. The knife handle structure reinforces the throat of the knife, by providing a double channel configuration comprising an outer channel with a blade retaining surface and an inner channel inverted relative to the outer channel and providing a blade supporting surface. The outer channel is tapered toward the inner channel about the throat of the knife, to reinforce the throat and prevent deformation under the stresses imparted by the knife blade when in use.
Abstract: A method is provided for sterilizing fluids using bolus dosing of a fluid, stretching of the bolus of fluid into a membrane, such as a thin or ultra-thin film, and subsequent irradiation of the individual fluid membranes which are then recollected after sterilization. A system is provided whereby a fluid moves along a defined pathway in traditional bolus flow where each bolus of fluid is interspersed with a bolus of gas. The bolus of fluid, for example from a patient or other sample, moves along the flow path and the width of the flow path is gradually increased until the fluid bolus is stretched (without breaking) to form a thin fluid membrane which can be completely panned using irradiation (such as ultraviolet irradiation) to sterilize the each bolus which has been stretched into a membrane. After sterilization the width of the flow path is gradually narrowed to a sufficient sized such that the bolus returns to a sufficient size to be collected, typically when it forms a small droplet.
Abstract: A telescoping hydraulic hoist which improves stability and rigidity in the extended position without sacrificing the maximum extension length of the hoist and with fewer machined parts which may be dislodged or damaged in operation. The base member has a recess into which intermediate and inner tube stages recede when the hoist is in a fully collapsed position, and a stop-collar on the gland nut bearings overlaps the exposed end of the next broader tube stage, defining a limit of retraction for each intermediate tube stage, so that a tube stage when fully retracted contacts the exposed end of the next broader tube stage, thus dispensing with the need for stop rings.
