Abstract: Two counter-rotating, intermeshing, toothed wheels grind opposite sides of an interposed blade to create or burrlessly sharpen a knife-edge on the blade. The wheels can be solid or comprised of a fixed stack of toothed disks, concentrically aligned, the teeth of each succeeding disk angularly offset in a common direction from the teeth of the next preceding disk to create a wheel having a plurality of uniform, elongated composite teeth around the circumference of the stack, the teeth being angled from the wheel's axis. Two such wheels, one with teeth angled in an opposite direction, can be counter-rotated and because of the oppositely angled teeth, are capable of intermeshing. The degree of intermeshing can be selectively varied to correspondingly vary the sharpening angle. The apex ridges of both the solid and composite teeth can be selectively profiled to sharpen non-uniformly, e.g. serrating a blade edge.

Abstract: A computing hardware and software device called a Meta Mentor Central Processing Unit. The Meta Mentor purpose is to control memory, input/output interfaces, defining the operating system, the scheduling processes and the parsing of individual threads to an array of slave Processing Units that are uniquely connected, thus creating a highly optimized computing core. In effect, the Meta Mentor tells the array of slave processors what to process by controlling all external and internal system input/output and individual processor scheduling.

Abstract: A bottle plate mates or is integrated with brackets for mounting a gas bottle atop the plate. An aft end of the bottle plate is spacedly affixed to a top of a base plate, the bottle plate being bendable about its aft end corresponding to the weight of a bottle mounted thereon. A plurality of guide pins disposed at a fore end of the bottle plate prevents lateral movement of the fore end with respect to the base plate, but allows to a limited extent displacement of the fore end due to bottle weight. Any displacement of the fore end due to bottle weight is converted to a corresponding bottle weight and a display indicates same to a user. The base plate is used to securely mount the apparatus.

Abstract: A cleaning blade system for a variety of electrophotographic apparatuses. A preferably reversible, elongated, elastic wiper blade is longitudinally supported by a relatively rigid, elongated holder. The wiper holder is universally adaptable to a variety of differently configured cleaning blade mounts by a plurality of mounting adapters which all have a uniform interface with the wiper holders so that all wipers and wiper holders can be uniform. Each mounting adapter has a second interface for fastening it to at least one of the varied cleaning blade mounts in the same way that a conventional cleaning blade is fastened. The holder and mounting adapters include provisions for locating and stabilizing the disposition of wipers relative to the drums. Preferably the holder includes an interlock securing a wiper blade without adhesives. The wiper blade may include flared edges to enhance contact pressure against the drum and extend its useful life.

Abstract: A laser assembly is removably attached to the shaft of a putter slightly above the head. The position and orientation of the laser assembly is adjusted to direct the laser horizontally in a plane passing through the sweet spot of the putter's face and perpendicular to the face when a user is addressing a golf ball with the putter. Once adjusted, the laser then can give accurate indications, against a backdrop, of the alignment of the putter with respect to a selected target hole, because the laser will illuminate a spot on the backdrop which is in accurate alignment with the putter, and thus allowing the golfer to compare his or her alignment prior to activating the laser. The laser is preferably momentarily actuated by a finger button attached to the putter at or near the grip.

Abstract: A buttocks seat is supported by a post tiltably affixed at a lower end to an upper face of a base. The post is also axially rotatable relative to the base, and threadably engaged with an underside of the seat for supporting the seat on the post, the seat squarely facing upright when the post is vertical. A hand wheel is affixed to the post for rotating the post relative to the seat and the base for selectively raising or lowering the seat relative to the base. A resilient bias urges the post to be vertical unless a seated user flexes his or her lumbar with sufficient force to overcome the bias. Preferably the post is tiltable over a conical range and the bias comprises a resiliently compressible, cylindrical ring coaxial with the post, and extending between and abutting the base and the underside of the seat.

Abstract: Two substrate leaves are coupled by a folded flexible circuit medium. Integrated circuit components can be mounted to opposite faces of both leaves. A signal terminal projects from one of the leaves. Both leaves include paths for communicating signals between their respective components and the terminal. Preferably the leaves are formed by two outer, rigid substrates each laminarly affixed to a respcective inner substrate, the inner substrates being separate sections of the folded circuit medium and the outer substrates being separated sections of a rigid circuit medium. Components are mounted to the exposed faces of the substrates. The fold includes paths for communicating signals between the leaf distal from the terminal and the terminal, the signal paths between one leaf and the terminal being closely matched in length and impedance to corresponding paths between the other leaf and the terminal.

Abstract: A conduit network on a bristle face of a brush communicates with a supply of cleansing or rinsing effluent under pressure, and dispenses the effluent generally uniformly over a wide area of the bristle face through distributed outlet holes. A preferred quick connector couples the network to the effluent supply. A valve controls the rate of flow into the network. Control of brush movement during washing and grooming is facilitated by: an adjustable strap securing a user's hand to a top control face, a finger wall projecting from the control face including finger stops, a palm heel catch, liquid drain-off channels which also knurl the control face for better gripping, and a preferred length allowing a user's fingertips to overlap the front of the brush.

Abstract: A roller skating device combining advantages of conventional roller and in-line skates, and skateboards is presented. A “boot” (as defined herein) for snugly encasing a selected foot of a user has an undercarriage, i.e. a frame, connected to it in fixed relation. A rigid member having a planar top is affixed to the undercarriage, preferably behind the heel of the boot, for engaging the free foot of the user, i.e., the foot not wearing this invention. A plurality of rollers, connected to the undercarriage, rollingly support the undercarriage, and all connected to it, on a skatable surface. The free foot engages the planar top by resting on and, at selected times, pressing forcefully against the planar top to help control the device during operation. Two exemplary embodiments are described herein: an embodiment having a rectangular pattern of rollers and an embodiment having a single line of rollers.

Abstract: A casino game apparatus having a table layout similar to, or the same as, a craps game table using conventional craps rules, but without the dice. The preferred embodiment uses a pair of ball blowers, each selecting a numbered ball from six balls, numbered from one to six. A pair of monitors display the selected balls as viewed from video cameras mounted above the ball blowers, one number per monitor. The sum of the pair of numbers displayed constitute the random number decision generation replacing the use of dice. An additional embodiment uses a random number generator to select two numbers for random number decision generation. Another embodiment uses two shuffled card decks from which to select two numbered cards for random number decision generation. An additional embodiment uses a remote control activated by a player to initiate the random number generator for selection of two numbers for random number decision generation.

Abstract: The output of a preamplifier is communicated to an active feedback circuit which drives the primary of a balancing transformer the secondary of which is connected in series with an impedance under test (IUT), the terminals of the series connection are communicated to respective differential inputs of the preamplifier. The feedback circuit automatically drives the preamplifier input toward balance, balance being achieved when the signal across the secondary equals the signal across the IUT in magnitude but opposite in phase. A DC blocking circuit is interposed between the series connection and the preamplifier for blocking preamplifier bias current from loading and heating the IUT. At balance an active equalizing transfer function circuit nulls any potential across the blocking circuit.

Abstract: A low profile, 1U expansion PC board for mounting at least two PCI connectors, mountable by a male-to-male connector to a PCI matrix on the transverse side of a 1U PICMG computer backplane. Additional mechanical security is provided by mounting stanchions between the board and the backplane.

Abstract: A cooler for cooling a plurality of brands of liquid beverages for delivery at taps for dispensing to customers at a desired chilled temperature. The cooler has a heat exchanger with a shell having channels passing through it, each communicating with a keg containing a beverage and a dispensing tap. Chilled coolant, controlled by the heat exchanger flows through the shell to cool the beverage flowing through the channels to the desired temperature. The temperature of the coolant is controlled by a temperature controller to maintain a narrow desired temperature range, just above the freezing temperature. The cooler is capable of cooling each of the channels without having to be installed in a walk-in cooler, allowing its installation proximate the serving taps. Also, the kegs containing the various brands of beer which are connected to the heat exchanger do not have to be kept in a walk-in cooler. 30° F. to 34° F. range.

Abstract: A telescoping wand safely encloses the control ends of a set of lift cords of vertically raisable “blinds” (as defined in the specification). The wand includes a selectively releasable cord locking mechanism which cooperates with a lift cord tensioner and a cord locking mechanism in the blinds' headrail to allow a user to raise and lower the blinds by one-handed operation of the wand. The blinds are raised by reciprocatingly moving an outer handle tube telescopically along a stationary inner tube. Each time the handle is pumped up and down, the blinds are raised a discrete amount. The wand's cord locking mechanism allows the lift cords to slip through the wand on the handle's upward stroke, but grabs and pulls the lift cords on the handle's downward stroke. Two or three quick pumps of the handle are all that is typically needed to fully raise a set of blinds.

Abstract: A set of modules from which custom passive backplanes can be assembled coplanarly couple together and are mounted on a rigid base plate which holds them coupled and coplanar. Each module has a plurality of orthogonally oriented card connectors. Preferably there is a CPU module into which is plugged a CPU card from which an ISA and a PCI originates. On one edge of the CPU module is an connector communicating with the ISA bus. This connector is for chaining together one or more ISA modules, each of which expands the ISA bus to three more ISA connectors. On an opposite edge of the CPU module is an connector communicating with the PCI bus. This connector is for chaining together one or more PCI modules, either 32-bit or 64-bit, each of which expands the PCI bus to three more PCI connectors. Power and ground can be jumpered from module to module or can be directly connected to any module.

Abstract: A hair cutting device is connected to a vacuum source to draw hair into a cutting chamber and includes a mechanism for cutting which allows an operator to both position the cutting device and to activate the cutting mechanism with one hand. The cutting mechanism includes two blades and preferably at least one blade slidably moves against the other to cut hair. The cutting mechanism also maintains the blades in proper position and applies pressure to at least one of the blades to ensure the proper cutting of the hair. Preferably non-parallel cutting edges and the bowing of at least one of the blades act to provide an effective moving shear point between the blades. The cutting mechanism also allows for continued airflow through the cutting chamber regardless of the position of the blades during the cutting operation.

Abstract: Low voltage, high current electrical energy is supplied in a closed conductive loop. Preferably, the current is induced into the loop by a transformer. The loop has, at least in part, one, or a series of, conductive elements of a structure to be warmed. The amount of current is sufficient in relation to the inherent resistivity of the elements to cause the generation of heat within the elements. Preferably the current is an alternating current of a frequency which causes a majority of the current to travel at or near the skin of the elements in order to increase the effective resistivity of the elements and thereby increase the generation of heat therein, primarily around the skin of the elements.

Abstract: A rigid surface upon which a person sits is elastically supported, preferably by a gas-filled bladder assembly which includes two inflatable bladders, one circumscribing the other. The bladders are preferably independently inflated, the inner bladder preferably being inflated to a higher pressure than the outer bladder to act as a fulcrum for the seating surface. The bladder assembly allows two degrees of movement for the seating surface, e.g., pitch and roll rotations about two mutually orthogonal medians. The two degrees of movement permits a user to exercise his or her lumbar cage muscles by seesaw movement of the lower body on the seating surface.

Abstract: A pizza warmer and oven system in which a plurality of pizza warmers containing a phase change material can be charged to their preferred temperatures by resistance heaters positioned in shelves above and below each warmer in an oven. One embodiment has top shelves biased in close proximity with the warmers. Moving a lever causes the upper shelves to be raised by cams, allowing removal or insertion of warmers. Insertion of warmers into the oven trips switches, starting timing circuits which energize the heater and charging indicator lights. At the end of the timing cycle, indicator lights signal the warmer's charged condition. In another embodiment, the top shelves are gravitationally biased down but are each free to move upward slightly for warmer insertion or removal. Turning on the oven energizes the heaters. A thermostat in the heater circuit turns off the heater at a pre-selected temperature.
