Abstract: A horse boot, for enclosing a horse hoof to at least above its coronet band, comprises a flexible enclosure molded and adapted to fit around a horse hoof. The enclosure has inner and outer surfaces, an upper opening, a bottom portion and a wrap-around wall portion integral with the bottom portion. The bottom portion includes upper and lower surfaces and the upper surface includes a marginal portion. The wrap-around wall portion includes an upper rim, inner and outer surfaces and a vertical slit. The slit intersects the upper opening and terminates substantially adjacent the bottom portion, thereby permitting the upper opening to be enlarged for putting on or removing the boot from the horse hoof. A belt and buckle assembly is operably associated with the wrap-around wall portion for securing the boot around the horse roof. The enclosure includes a layer of absorent cloth material bonded to the inside surface thereof.

Abstract: The process for securing a machine tool bed to a base includes the steps of providing a base having a horizontally disposed first surface wherein a plurality of cooperating grooves are disposed. A selected quantity of hardenable grout material is deposited into the grooves. A bed has a second surface from which a plurality of tongues extend, and each tongue has side surfaces which are relatively rougher than the associated distal surface. The bed is horizontally positioned above the base so that each tongue is received in an associated groove and each distal surface is spaced from the associated underlying groove, thereby causing the grout material to rise by an amount insufficient to contact the second surface. The bed is maintained spaced above the base until the grout material has hardened and thereby binds each side surface but not the associated distal surface to the base.

Abstract: Package handling apparatus comprises an enclosure having a downwardly directed opening, a source of air flow arranged to draw air into the enclosure through the opening, and lowers for varying the air flow into the enclosure. A conveyor is arranged in the opening and is movable relative to the opening, the conveyor being positioned to be in the flow of air into the enclosure and to provide a movable support for a package which is urged against the conveyor by the flow of air past the support.

Abstract: A feeder tray for baby chicks comprises a peck-disintegratable bio-degradable fiber receptacle. The receptacle is adapted to be completely disintegratable into tiny particles by the end of the brooding period from the pecking of the chicks so that the tiny particles will substantially decompose on site, thereby eliminating the necessity to remove and dispose of a feeder tray after the chicks have outgrown the need for a feeder tray.

The elongated frame may alternatively be suspended from a peripheral base frame within an open space defined thereby.

Abstract: An automatic control device for a hot water heating system, comprises a first relay being connectable to a water temperature switch such that the first relay is energized when the switch is closed and a second relay connected to the first relay such that the second relay is energized when the first relay is energized. The first relay is connectable to an electrically operated valve controlling the flow of high temperature water from a boiler to a heat exchanger operably associated with a water heater such that the electrically operated valve is opened when the first relay is energized and closed when the first relay is de-energized. The first relay is connectable to the boiler such that the boiler is turned on when the first relay is energized.

Abstract: A self aligning guide system for one or more circular saw blades allows the guides to be aligned while the saws are rotating at operating speed under no load. The system includes at least one saw blade mounted on a shaft and has a first guide block having a face engageable with one side face of the saw blade and a second guide block with a face engageable with the other side face of the saw blade, a guide housing containing the first and second guide blocks, the guide housing slidingly mounted on an elongate member substantially parallel to the saw blade shaft, clamp means to clamp and unclamp the guide housing on the elongate member, and remote operational means to effect the clamping and unclamping of the guide block on the elongate member.

Abstract: A door harp having a body portion with a front face and a back and at least two spaced apart pegs mounted on the front face having a tensioned string extending between them and a pendulum like chiming device extending from a bracket mounted on the front face above the string in a position to strike the string when the door harp is moved. The door harp also includes a cavity formed in the back forming a resonance chamber and a sounding board. A groove extends from the bottom of the cavity towards the front face of the body portion and surrounds the sounding board.

Abstract: The invention provides a rope splicing apparatus having an elongated tool portion including a main portion, a tip portion and a transitional portion. The main portion comprises a pair of straight and parallel main rod portions which are spaced apart at a main portion width along the length thereof. The tip portion comprises a generally U-shaped rod portion having a bend portion and leg portions which are spaced apart at a width narrower than the main portion width. The transitional portion has a pair of short rod portions flaring outwardly from the tip portion to interconnect the main rod portion to form a unitary tool. The tip portion is of a size which can penetrate strands of a single or dual braid rope to draw portions of the rope therethrough. The apparatus is used to practice a method of splicing such ropes to form eye splices, and marriage splices, with less difficulty than using conventional fids.

Abstract: A slide projector having a projector frame and a light source and lens assembly mounted on the frame which includes a cassette having a plurality of slide frame receptacles for receiving slide frames therein. The cassette is movable so as to bring selected slide frames into a dispensing position. A frame grabber mounted on the projector frame is movable in a direction perpendicular to the lens axis from a projection position in which an image of an engaged slide can be projected to a dispensing position in which slide frames can be sequentially brought into alignment with the grabber. Once engaged by the grabber, a selected aligned slide frame can be extracted from the cassette and moved to the projection position.

Abstract: A solenoid operated flush valve has a main flush valve body including water inlet and outlet means. The main flush valve body includes generally horizontally extending nipple means which is in fluid communication with the water inlet and outlet means. A flow control means is removably mounted within the nipple means and includes valve insert means and solenoid means in cooperative engagement with the valve insert means. The valve insert means includes first and second ends and a side. The valve insert means includes a first passageway extending axially between the first and second ends thereof and a second passageway extending between one of the first and second ends and the side of the valve insert means. The second passageway is in fluid communication with the water outlet means through the side of the valve insert means. Means cooperate with the solenoid means for selectively blocking the second passageway to thereby regulate the flow of water flushing through the flush valve.

Abstract: The encoder/decoder comprises a spherical body on which is provided a plurality of different letters and/or numerals. Connecting means in the form of three circular members sharing the same axis encompass the sphere, two defining two parallel sighting hoops and the third defining a sighting ring. The connecting means are mounted on a support body so that the relative rotation of the connecting means and the body can be effected. In use, the body is rotated until two specified indicia lie usually between the two sighting hoops in a specified order. Then, one or more indicia are read from the sighting ring. The encoder/decoder may be used to protect computer software against copying, and may also be used to hinder unauthorized access to remote computer systems. Thus, the number of individuals using a system can be limited to the number interrogating the user, can determine whether he has in his possession a suitable encoder/decoder such as outlined above.
