Abstract: An anchor for use in association with a mortarless block wall system for attaching facing to the outside of a wall. The wall includes a series of blocks placed in linear courses or rows with each block containing a pair of parallel sidewalls that are connected by lateral walls and at least one upwardly disposed projection for interlocking one block to another. At least one of the sidewalls has a laterally disposed groove formed therein which passes downwardly through the top surface of the block and is located adjacent to an end face on one of the lateral connecting walls. A wire anchor is seated within the groove which has an inwardly extended locking member that engages the connecting wall of the block. The anchor further contains a forwardly extended closure key that is adapted to pass over the outside face of the block. The closure key and locking member coact, in assembly, to hold the anchor securely to the block.

Abstract: A pneumatic tube send/receive terminal has a dispatch carrier that is movable between a load position and a send position. A sprocket chain fits on two sprockets and rotates under motor power, and a cam is mounted on the chain. A clapper valve or cover is hinged to a trolley or carriage that also rotatably holds the dispatch holder. A block or cog attached to the chain connects to the dispatch holder, and this rotates the same 180 degrees and then moves the trolley and the dispatch holder laterally to the send position. The cam rides a camway on the valve, and normally holds it shut, but when the chain is moved, the cam rotates over the camway and releases the valve so that it opens, and any received pneumatic carrier drops out. Rotation of the dispatch holder 180 degrees prevents inadvertent accessing the pneumatic tube with a second carrier in a single send operation.

Abstract: A apparatus for maintaining precooked food at a desired temperature includes a stationary hollow housing mounted in the bottom part of a warmer for holding a quantity of food.

The eyelet can be turned to any alignment desired and locked in place using a locking nut.

Abstract: A dust separator including a cylindrical housing that is separated by a pair of spaced apart tube sheets into an upper incoming air distributor, an intermediate tube compartment and a lower settling chamber. Large diameter air permeable filter tubes are suspended between the tubes to conduct airborne particles and dust captured inside the tubes into the settling chamber. A dirty air inlet is provided in the distributor while an air outlet connected to a blower is mounted in the lower part of the tube compartment. The blower draws air from the distributor through the tube walls so that the air is cleansed of airborne materials. A perforated control baffle is placed in front of the discharge opening to provide for a uniform and even flow of air through the tubes.

Abstract: Apparatus is provided for profiling the end faces of pipes or tubes. The apparatus comprises a shaft one end of which is insertable into the open end of a pipe or tube to be profiled, collett means on said one end of the shaft, and cutting means rotatably mounted on said shaft for profiling the end face of the pipe or tube. The collett means comprises first and second screw threads of opposite hand on said one end of said shaft, a nut in threaded engagement with each of said screw threads, the nuts being movable in opposite directions along said screw threads when the shaft is rotated, and engaging means supported on said nuts and movable radially of said shaft into or out of engagement with the internal surface of the pipe or tube when the nuts are moved along said screw threads by rotation of said shaft. The screw threads are preferably coarse threads which with the differential effect of the opposed screw threads provides rapid engagement and disengagement of the collett means.

Abstract: A bark camouflage cloth mimics the rough bark of a tree. The camouflage pattern on the cloth consists basically of rough, highly elongated vertical ribs of a first light or countershaded earth tone, vertical channels of a second, darker earth tone, and black vertical shadow edge markings along one side edge of each of the ribs. Islands of a third color, e.g., a greenish hue, are interspersed among the vertical ribs. The pattern of vertical shadow edge markings changes from left to right across the pattern to create the illusion of curvature of a tree trunk.

Abstract: A self-sharpening hole punch for plastic bags includes a pneumatically operated punching apparatus for punching wicket pin receiving holes in a flexible film or plastic bag. If desired, a tear slit may be simultaneously formed to enable the bag to be quickly and readily torn free from the wicket pin upon which the bag is retained. The disclosed embodiment utilizes a pneumatic air cylinder having a free end of the cylinder rod having a fitting secured thereto having an internal tapered bore. Interchangeable plastic cutting tools, having a complementary tapered thread, may be interchangeably threaded into the fitting to facilitate replacement as necessary.

Abstract: A protective shield that is adapted to overlie the collar of an outer garment such as an overcoat to protect the collar from being stained by hair gel or oil. The protective shield includes an outer or upper layer of real or simulated leather having a smooth, non-absorbent surface from which any oil or grease can be easily removed without staining. The outer, non-absorbent layer is connected to an inner cloth layer or lining that engages the overcoat collar and includes means for releasably attaching the protective shield to the overcoat.

Abstract: A sleeved gown is formed with an integral hood having a narrow front opening in line with the eyes of the wearer. The material of the gown is held in close contact with the wearer's face across the forehead and below the eyes but above the nose by means of tapes tied around the hood. An exhaust duct extends over each of the wearer's shoulders beneath the gown and has a plurality of exhaust inlets in the region of the wearer's chest. Preferably, upward airflow is restricted to a vertical passageway formed by an outward billowing of the gown material. This arrangement is most effective in drawing away air-borne emissions from the wearer's body and causing ambient air to enter from the bottom of the gown and gaps at each side of the wearer's nose. It is more comfortable than previous arrangements as there is no rigid mask or visor. Also as air extraction does not take place adjacent the wearer's face, no special communication equipment is required.

Abstract: A disposable seal is provided for a luer lock end fitting, e.g. for a biopsy channel of an endoscope. The fitting has a tubular luer lock device and a retaining ring surrounding the tubular device. The seal is unitarily molded of a soft elastomer and has a double seal arrangement formed of an apertured end wall and a one-way-opening slitted plate or web behind the end wall. A distal end of the seal fits over the tubular luer lock device. This distal end has a radial cuff that seals against a flat transverse surface of the retaining ring and a frustoconic tapered protruding member which fits against a similar inner surface of the retaining ring to ensure that the cuff sealably engages the retaining ring under overpressure conditions.

Abstract: A modular family tree doll system has a modular tree formed of a base member, modular trunk sections that snap-fit together, and modular branches that fit to one another and to the trunk sections. Dolls that represent progenitors of either gender back through several generations can be placed in doll swings or treehouses that are suspended from the branches of the tree. Flags can indicate the country of origin for the person that the doll represents, and the doll swings or treehouses, and cushions on the fixed swings or treehouses can be color coded to indicate blood lines. The system can be free standing or can be suspended on a wall, and can be expanded as more is learned about the ancestors.

Abstract: Apparatus for mechanically transferring energy from a source to some form of energy converter that includes a series of gear sets placed in meshing contact between the source and the converter. Each gear set includes a liftoff wheel that is coupled to a transfer wheel by means of liftoff units which realign the internal forces acting upon the system when the wheels reach or exceed liftoff speed. The realignment of forces neutralizes the internal forces and conserves the amount of energy needed to sustain the transfer operation. The energy saved is accumulated in the system and used to do work.

Abstract: An ophthalmoscope having two lens discs one of which has three different lenses and the other of which has twenty-three different lenses. There is a viewing path through the instrument and, in use, one lens in each disc will always be in registry with the viewing passage. The two lens discs in combination provide sixty-nine different diopters ranging from -30 to +38 diopters. The lens discs have a common axis of rotation and are spaced apart so as to permit a cam plate to be positioned between the discs in close proximity to each. The cam plate is operable to provide an automatic lens shifting mechanism for the pair of lens discs.
