摘要： A modular "knock-down" type shelving system having adjustable height shelves includes a plastic support post having a generally right equilateral triangular cross-section. The support post is composed of pultruded thermosetting plastic having unidirectional E Glass fibers extending therethrough and a thermoplastic coating bonded to the outer surface thereof. The inner surface of the interior side of the support post is bowed outwardly. As a result, when a wedge member is disposed on the interior side of the post and the support post and wedge member combination supports by wedge action a sleeve comprising an end beam and a collar, the interior side of the support post is urged outwardly and is supported by the wedge member. The collar is locked to the end beam when a tongue of the collar passes through a slot in the end beam into a rotatable lock in a blind hole in the bottom of the end beam. A plurality of shelves are adapted to be snap-fit over a rectangular support structure comprising two end beams, and two side beams and a center beam connecting the two end beams. In this manner the shelf can be easily assembled and disassembled and supported on a support post at a predetermined height.

摘要： A dental X-ray aiming device adapted to place an X-ray film packet having sharp edges at a proper position in the oral cavity of a patient. The device includes a packet holder that serves to shield the sharp edges of the packet to avoid direct contact with tissue within the oral cavity and the resultant discomfort, pain or trauma. The holder is formed by a rectangular frame of resilient plastic material within which the packet is socketed, and a bite block joined to the front of the frame which, when clenched between the teeth of the patient, then places the held film packet behind a tooth region to be examined. The device also includes a distance-calibrated guide rod which is detachably coupled to the bite block, and a sighting ring adapted to receive the nose cone of an X-ray unit, the ring being slidable along the rod to a desired position thereon, whereby an X-ray beam is projected from the nose cone in accurate relationship to the film packet.

摘要： A tamper-proof fastener provided with a threaded shank and a low-profile drive head integral therewith. The drive head has a generally frusto-conical shape defining a circular flat top and a circular base of larger diameter, three short noses separated 120 degrees apart projecting from the sloped side of the drive head. The fastener is installed in a substrate or withdrawn therefrom by means of a tool having a driver head provided with a complementary frusto-conical socket to accommodate the drive head of the fastener, the wall of the socket having recesses therein to receive the noses of the head whereby a torque may be applied thereto.

摘要： A compact storage system, mountable for operation on a flat base platform, includes at least one guide rail having a roof and two legs depending from the roof thereby defining an inverted, generally U-shaped continuous channel. The guide rail is mounted in spaced generally mutually parallel relation to the base platform with its legs projecting toward the base platform so that the channel opens downwardly. The compact storage system further includes at least one movable storage unit that is supported for translational movement on the base platform. One or more guide rollers are mounted on the storage unit to be received in the channel of the guide rail with the guide roller being formed to engage either one of the legs of the rail for movement relative thereto. Accordingly, translational movement of the storage unit is confined to a path defined by the guide rail.

摘要： A waste compaction and liquid extraction system and method are provided. The system includes a tank for containing liquid and solids, and a tray that seats on the tank. The tray includes a feeding mechanism for moving bags of waste across the tray, and a stuffing mechanism for pushing the bags down into the tank. A rotary disc impeller is mounted in the tank for grinding the solids to form a mixture of liquid and solids. The impeller has a rotating blade with inclined and bevelled cutting members. A stationary helical screw is horizontally mounted to the output port of the tank. The screw has a receiving end adjacent to the output port and a discharge end. The tank conducts the mixture to the receiving end of the screw. A sieve is provided having a cylindrical sieve surface surrounding the screw. The liquid drains through the sieve. The sieve is rotatably mounted to the output port of the tank. The sieve rotates about the screw to move the solids longitudinally towards the discharge end of the screw. A restrictor at the end of the sieve maintains backpressure to squeeze liquid out of the partially dried solids. A housing surrounds the sieve. The housing is mounted to the input port of the tank for communicating liquid that drains from the sieve back to the tank by way of the input port.
