Abstract: A tire chain installation tool comprises an elongated member that is connectable to a traction chain or other traction device and that acts as an extension and guide for leading or pulling the traction chain onto a tire. The tool receives one end of the tire traction chain, and an elongated belt of the tool is placed around the tread surface of a vehicle tire. Upon rotation of the tire due to movement of the vehicle, friction between the tire and belt (and capture of the belt between the tire and the ground/road) cause the belt and hence the tire traction chain, to be drawn around the circumference of the vehicle tire. Thus, the traction chain is placed in good position to be fastened without the struggle and discomfort frequently associated with installing chains on a vehicle. The preferred belt is easier to lift and manipulate than the traction chain and does not need to be positioned or manipulated in the space behind the tire (away from the user) or in the space between dual tires.

Abstract: A valve system lifter for combustion engines includes a hard metal face pad connected to a lower-grade metal lifter body. The connecting material is one or more materials that are different from both the lifter body and the face pad. Preferably, the connecting material is a silver-and copper-containing material, that may take the form of a wafer with silver or silver alloy layered over a copper alloy core. The preferred body includes one or more ferrous compounds, and the preferred face includes tungsten carbide. The resulting lifter is resistant to the cracking, breakage, and wear that plague conventional lifters, due to the harsh temperature and impact environment of the lifter. The resulting lifter may be used to reduce the need for change-out and down-time in many engines.

Abstract: The invention is a multifunctional law enforcement tool, which includes several of the tools needed by law enforcement and security personnel. In one embodiment, the multifunctional tool comprises a flashlight, deterrent spray dispenser and removable cartridge housing. The cartridge housing is an open bay on the tool, and is adapted to receive cartridges which allow the user to fire non-lethal rounds such as bean bags, rubber balls, O.C. powder, multiple probe neuromuscular disruption rounds, and many other projectiles. Inserted cartridges also fire tactical rounds such as colored smoke, breach rounds, and concussion rounds. In addition, the tool may optionally include LED light, stun gun, stun projectile, glass breaker, I.D. card holder, pistol mount, laser sight, and audio microphone or audio/visual camera. Additionally, a standard defense, ballistic defense and/or electrified “stun” shield may be attached to the tool.

Abstract: A hook-setting device, including a flange that is fixed and generally transverse to a fishing line or leader, is adapted to resist the force of a fish strike on a hook or fly and to also indicate a strike by its movement in the water. The flange preferably floats at or near the top of the water, in a partially-submerged position, with a generally concave front surface facing the hook or fly. The front surface forms an open cup-shape that partially or completely fills with water, thereby providing resistance to the flange being pulled through the water and thereby setting the hook/fly in the fish's mouth. The preferred flange also features a generally convex rear surface facing away from the hook or fly, which rear surface is the leading surface during fly-casting, reducing air resistance during the cast and contributing to proper laying-out of the fly at the end of the cast.

Abstract: An automatic paper ejecting and stacking machine for use with vertically-loaded desktop hole-punching equipment is disclosed. The ejector and stacker work together to remove vertically-fed paper stacks from a hole punch and align said stacks in a horizontal stacking bin adjacent the punch machine and preferably facing the operator. After the sheets are punched, a sheet transfer mechanism moves the vertically-oriented media stack in a horizontal direction from the punch machine/ejection assembly to the reception assembly. The sheet transfer mechanism may comprise a plurality of transfer paddles arranged on an drive belt wherein a motor rotates the belt to draw a paddle through the paper-receiving channel of the ejection assembly to push the media stack out of the channel. In one version, the media stack is flipped forward to rest in a forward-facing tray, while in another embodiment, the media stack is pushed rearward to rest in a rear-facing tray.

Abstract: A nutcracker utilizes a conical member with a textured exterior surface rotatably mounted and centered inside a vertical cylinder with a textured interior surface. The nuts occupy a cracking zone between the textured exterior surface and the textured interior surface. As the conical member rotates, gravity rolls the nuts down in a spiraling path into an increasingly smaller cracking zone until the pressure on the nuts between the textured exterior surface and the textured interior surface causes the shells to crack and the nuts to break into halves and thirds.

Abstract: A bracket system holds one or more filters in quick-attach and quick-release fashion. Bracket modules are combined in modular fashion, with tubing or other conduit between the modules, to create a “bank” of filters easily changed in number, arrangement, and flow scheme. Preferably, the bracket system comprises pairs of top modules and bottom modules that capture and support the top end and bottom end of a filter. Filter inlet and outlet ports preferably slide onto and off of cooperating tubes or ports in the bracket modules, for installation and removal of the filters onto/from the modules without tools or threaded connections. A top retaining member preferably pivots off of its respective filter, so that the filter may be lifted up off of its respective bottom module. The bottom modules may be pivotal, so that lifting the filter up from the bracket system is facilitated by allowing the filter top end to also pivot out away from the top module.

Abstract: Embodiments of a key system for filters and their connecting heads, brackets, or other holders are shown. The filter cartridge and its holder each have a keyed surface, one being a protruding “key” and one being a recessed “lock”. Cooperation of these keyed surfaces is required in order for the filter cartridge to be installed in the holder, so that mis-matched cartridges cannot be installed into the holder, for example, to prevent a particular type of cartridge from being placed in a filtration or other process where it would be inappropriate, or undesired. The keyed surfaces are selectively locate-able preferably at different circumferential locations on a perimeter of the filter and a corresponding location on a perimeter of the head/holder. The perimeter may be, for example, on an outer shoulder surface of a filter and an inner surface of a valve head, or on outer and inner surfaces of connectors that provide a liquid seal between the filter and the head/holder.

Abstract: The present invention is a saboted projectile with external ridges and/or an internal locking edge for muzzleloading firearms. Also, the present invention is a sabot with the ridges and/or locking edge for receiving a muzzleloading projectile. The sabot has a forward part and a rearward part. The forward part has a plurality of axial panel sections separated by narrow, axial slots. The panels have radial ridges on their outside, or external surfaces. Also, the panels have a radial ridge on their inside, or internal surfaces. The external radial ridges assist in convenient loading of the muzzleloading projectile, while still providing enough contact with the inside of rifle barrel to capture exploding gases and prevent blow-by. The internal radial ridge assists in securing the sabot to the bullet, especially when the bullet has been provided with a cooperating radial indent, cannelure or retaining ring.

Abstract: An attachment system secures a residual limb to an artificial limb in a comfortable and substantially non-rotational manner. The attachment system offers proximal anchoring of the residual limb in a hard socket, by connecting a side surface of a residual limb liner to the side surface of the socket. Preferably, this connection is accomplished using an extension member extending from the liner through a portion of the socket interior, through the socket wall, and attaching to a latch mechanism. The preferred attachment system requires no clearance in the bottom of the socket well because neither the extension member nor the latch mechanism is located between the distal end of the residual limb/liner and the bottom of the well. The attachment system is preferably disposed entirely along the side of the limb and the side of the socket.

Abstract: A bracket system holds a filter(s) in quick-attach and quick-release fashion. Brackets are combined in modular fashion, with conduit between the brackets, to create a “bank” of filters easily changed in number, arrangement, and flow scheme. Top brackets and bottom brackets capture/support the top end and bottom end of a filter, respectively, and filter inlet and outlet ports preferably slide onto and off of cooperating tubes/ports in the bracket modules without tools or threaded connections. A retainer may pivot on and off of its respective filter, holding the filter in place and releasing the filter, respectively. After pivoting the retainer up from the filter, the filter may be lifted up off of its respective bottom module, so that the filter is substantially vertically and pivotally removable from the bracket system.

Abstract: A carriage of the types commonly used in skyline logging operations. The invention facilitates moving logs along a suspended skyline by means of a hoisting system built into the carriage comprised of a radio controlled electronics system, an internal combustion power plant, proportional controlled hydraulically driven skidline sheave, a skidline clamp and skyline clamp. A novel method of pump control keeps the internal combustion engine operating within its power band. The volume output of the pump is controlled by engine RPM to adjust the pump's load on the engine. Combined operation of the various controls on the carriage, in conjunction with the controlled operations of the yarder winch at the end of the skyline, result in a system well suited for efficient logging operation. The choker/setter (ground crew) and the yarder are able to remotely control the carriage operation as a team. The carriage controls of the present invention are primarily hydraulic, actuated by means of electrical solenoid valves.

Abstract: A card-like apparatus may be used as a card, a bow, a decoration, or other item, and is preferably made from a single sheet having an interior central region in the shape of a regular polygon defined by fold lines between the central region and a plurality of extremity panels. The panels fold across and beyond the central region, forming an outer perimeter that represents a flower, plant, holiday novelty, animal, person, or other object or living thing. Decoration such as paint, print, artwork, or a portion of a picture may be added to the panels so that the folded panels further represent the object or living thing. Methods have been developed to dissect a whole picture and then to lay or copy sectors of the picture onto distal portions of the panels, so that upon folding of the panels, the distal portions are visible, over and beyond the central region, in positions wherein the picture comes together again as a whole.

Abstract: A turbine generator regenerative braking system may be used to slow or stop a rotating shaft or wheel, wherein energy may be recovered as electricity generated by a turbine generator and stored in batteries, ultra-capacitors, or other storage systems. The turbine generator may be fluid-jet powered, the fluid-jet being provided by at least one hydraulic fluid pump linked to the rotating shaft or wheel. A braking actuation system operatively connects/starts the pumping action, and controls may be provided to adjust the flowrate through the fluid-jet nozzle. In some versions of the system, a hydraulic pump, a clutch, and an adjustable-flow nozzle will be dedicated to each ground engaging wheel of the vehicle. In a vehicle, braking is preferably initiated by the driver by actuation of a brake master cylinder that provides hydraulic pressure to cause each hydraulic pump to engage with its corresponding pump. The pressurized fluid output of each pump is then fed to the turbine through the adjustable-flow nozzle.

Abstract: A high thermal efficiency lean-burn spark- ignition two or four stroke engine operable unthrottled suitable for vehicles using gasoline. It uses an indirect combustion chamber and a transfer orifice with or without shaping of the combustion chamber to produce a jet of air moving in helical swirl motion around the chamber during the compression stroke. Fuel is injected into the chamber aimed into the air jet to assist rapid vaporization. The position and orientation of the fuel injector ensures that fuel arrives near the spark plug even under idling conditions and the helical swirl flow ensures the stratification of the ignitable mixture formed near the plug. The compression ratio of the engine can also be variable.

Abstract: An adjustable stand includes a stable base, an upright portion upending from the base, and a platform adjustably locked in the base. The platform height preferably may be adjusted continuously rather than incrementally for precise and accurate positioning of a horse hoof or other animate or inanimate object. One platform includes a diverging U-shaped cradle, with a firm but cushioning/shock-absorbing material on its top side for elevating the supported object and absorbing the concussion of the work being performed on the object. Preferably, the firm but cushioning material is a flexible strap slung across the cradle and spaced above the surface of the cradle at its center region. The preferred plastic base and continuous adjustability of the platform provide a quiet, substantially non-metallic, and non-intimidating stand that tends not to frighten horses or other animals.

Abstract: The present invention is a system and method for removal of buried objects. According to one embodiment of the invention, a crane with a vibrator casing driver is used to lift and suspend a large diameter steel casing over the buried object. Then the casing is driven into the ground by the vibratory driver until the casing surrounds the buried object. Then the open bottom of the casing is sealed shut by injecting grout into the ground within the casing near its bottom. When the seal has cured and hardened, the top of the casing is lifted to retrieve the casing, with the buried object inside, from the ground.

Abstract: A foot operated data entry pad has a plurality of foot buttons. The foot buttons are used to enter data values—e.g., numbers or symbols separately or in combination. Each button is capable of entering different data values, preferably depending on the length of time that it is pressed or on the number of times that it is pressed in succession. A small controller may be included to allow the user to control the computer's pointer, allowing the user to switch between data entry fields, as with a mouse. An automated voice system, or other audible and/or visual indicator system, may also be included to help the user keep track of the data value as it changes and is entered. Various embodiments are capable of entering a variety of alphanumeric data rather than a simple binary-type data set, such as yes/no or on/off, or instructions, such as a joystick used with a flight simulator program. Multiple data entry pads may optionally be used in conjunction.
