Abstract: A crawling insect-proof pet bowl having an outer liner with upwardly sloping sides and downwardly sloping lip. An inner liner that conforms to the outer liner but that has upwardly extending sides that angle away from the sides of the outer liner and thereby forms a gap. The inner liner has a downwardly sloping lip that extends beyond the peak of the inner liner and partially down the downwardly sloping lip of the outer liner. The tip of the outer liner extends beyond the tip of the inner liner so that if the bowl is pushed against an object, such as a wall, direct access to the inner liner bowl is prevented. The gap formed by the upwardly extending sides of the outer and inner liner forms a barrier to the crawling insects and is particularly effective when armed with a biodegradable substance such as petroleum jelly. As a result, a spill-proof, long life, barrier to crawling insects is provided that is non-toxic, biodegradable, and easy to replace and clean.

Abstract: A safe radiation shielded seed loader for hand implanter hypodermic needles with removable seed loading disk. The removable seed loading disk enhances the ability to quickly and safely load radioactive seeds into hypodermic needles. As a result, the loading process is greatly expedited and a substantial reduction of the radiation exposure time to hands, fingers and eyes of the person loading the seeds is accomplished. Once loaded, a spacer-key prevents obturators from pressing the loaded seeds, now carried in a shielded container, out of the needles until use. A removable carrying handle with lifting arms and a cover plate with a recessed area to accommodate the heads of the obturators is provided. As a result, the easily and quickly loaded device may be safely transported to the implantation site without fear of radiation exposure or damage to the needles themselves.

Abstract: A door closure apparatus for processing a wafer paddle used to support microchips in a process tube using the chemical vapor deposition process. The device has a flexible joint which enables the sealing door to squarely seat against a processing tube whether or not the processing tube is correctly aligned. Further, the device has an adapter which enables paddles with variously shaped handles to be accepted in the standard processing tube as if the handles were round.

Abstract: An interiorly located, rotating, self sharpening, replaceable digging tooth device having a removeable cap that fits over and is attached to a shank on an excavating machine, a replaceable digging tooth mounted within one end of the cap and a female socket in the cap for receiving and retaining the tooth and allowing it to rotate therein so that the tooth is self sharpening. The removeable cap is conformable to any sized shank on any excavating machine and has a front portion that is primarily solid within which the digging tooth is inserted. As a result, the digging tooth, much like a human tooth, is much better able to resist shear forces applied to it. More than one digging tooth may be provided per cap and as many caps may be provided as there are shanks on an excavating machine.

Abstract: A restricted purpose, commercial, monetary regulation method is provided whereby a network is established between the business user, the acceptor of the restricted purpose card and a financial institution so that the business user obtains a unique identification number that enables him to purchase only one specific product or service from the acceptor. As a result, employers are free to give this card to employees without endangering the employees by entrusting them with large sums of cash or currency and while also ensuring any use of the card will be for a purpose authorized by the business. Once the validity of the card is authenticated, the transaction is completed by the acceptor, the information is transferred to financial institution and the funds are transferred from the user's account to the acceptor's account.

Abstract: A hand-held wild-seed reaping apparatus and method having a motor mounted on a frame for driving a cutting mechanism which is surrounded by a containment box with an open front and rear end. A cutting collector attached to the open rear end of the containment box is provided to retain cut seed which has been selected by the user for harvesting and which is removably attached to the frame of the invention. As a result, users can harvest seed wherever walking is possible, even in steep, rocky or brushy territory. Further, they are enabled to be very selective in cutting, therefore harvesting only selected species and avoiding unwanted species.

Abstract: A trailer of the container roll-on, roll-off type having a self contained power plant thereby being capable of full operation for loading and unloading regardless of the type of towing vehicle or in the absence thereof. The device is multifarious in uses, in that amoung other capabilities, it may be used as an ordinary flat bed trailer when not in use as a tilting roll-on, roll-off trailer. The device is capable of production in a multitude of sizes making it adaptable to a wide range of needs and uses within the financial means of many who previously have been excluded from ownership of such a vehicle.

Abstract: A coupling for attaching one mechanical device, such as a truck, to another mechanical device, such as a trailer, by the use of a rotatable sleeve located around a coupling arm on which is positioned a socket member with one or more free floating cam which are allowed to move in and out of cam openings by rotating the rotatable sleeve, thereby locking or releasing a ball, or other type, of hitching member in the socket area. The coupling arm and rotatable sleeve can be fashioned in varying lengths so that the hitching ball, or other type of hitching member, can be located in recessed or otherwise remote and inaccessible areas and still be utilized for towing.

Abstract: Apparatus and method of providing for a semi-automatic crossbow embodying a new cocking device and a new magazine. The cocking device consists of a pulley system mounted to the frame of the crossbow and operated by a filament. The crossbow is cocked by holding the grip of the device in one hand, and pulling the cocking handle with the other hand. Each time the crossbow is cocked, a pulley carriage is automatically returned to its original position by use of springs or elastic bands. The device may be fired as quickly as the device may be cocked and trigger pulled. A clip device is utilized to hold bolts to be fired. The bolts are stacked vertically and spring fed upwardly to the chamber each time the crossbow is cocked. The bolts are held in place by constant spring pressure against the bolt track along which the bolt are driven. The clip utilizes two arms that scissor upward and raise the bolts substantially levelly.

Abstract: Apparatus for dispensing fluids to a plurality of receptacles simultaneously, equally, and without dripping. A distributing device is used that uses a major-minor channel configuration such that all major channels fill with fluid before the minor channels fill and all minor channels fill before water exits the outlet holes in the bottom of the distributor. A stand is included which supports the fluid to be distributed and which is designed to exactly center common communion trays beneath the distributor for filing. A stretchable transfer tube connects the fluid in the container with the distributor and, when pinched shut, causes fluid to be sucked back up the tube and which in conjunction with the pipette action of the outlet holes prevents drippage after filling.

Abstract: A portable reversible chair apparatus with pivotal connections enabling the device to be converted from a "posture" chair configuration to a conventional chair configuration simply and quickly. While the device is in the "posture" chair configuration adjustments are possible that allow users of different size to select the seat angle and the seat to knee rest distance which is most comfortable for them. The knee rest is designed to flex in the verticle plane allowing the seated user to shift weight and position comfortably and safely. The critical joints of the chair pivot thus eliminating racking of joints. Rigidity is derived from triangulation rather than from the size of the joints. The device is very stable due to its large base and sits well on an uneven surface because it rests on three points rather than the traditional four.
