Abstract: An adjustable, battery-powered, constant pressure gun (10) for dispensing viscous materials such as caulk and adhesive. The gun (10) includes a housing (12) having a handle (14), an operator-actuated trigger (40), and a battery compartment with power supply terminals (32). A motor (26) mounted within the housing drives (12) a dispensing mechanism (24). The flow of current through the motor (26) is controlled by an electronic switch (70). A current-to-voltage converter (72) including a low-pass filter (88, 90) is coupled to the motor (26) and provides a feedback pressure signal representative of the actual dispensing pressure as a function of the current drawn by the motor (26). A set-point voltage signal representative of a desired dispensing pressure is provided by an operator-adjustable pressure control (36). A hysteresis comparator (74) connected to the electronic switch (70) compares the feedback pressure signal to the set-point signal, and controls the switch as a function of the comparison to maintain the actual dispensing pressure within a predetermined operating band of the desired dispensing pressure when the trigger (40) is actuated.

Abstract: A device and a method for contouring an ice skate blade. The method comprises the steps of measuring the overall length of the soleplate of the boot and calculating the center point of the soleplate, transferring the center point of the soleplate to the blade and marking the center point of the soleplate onto the blade as the first calibration point. A second and third calibration point, calculated as 25 % of the soleplate length are marked from the first calibration point towards the toe and towards the heel of the blade. Toe and heel radius termination points are also marked. The device comprises a measuring tool for measuring the length of the soleplate and having calibration points and radii termination points preset on the device according to the soleplate length. The device therefore eliminates the calculation of all the calibration points and radii termination points each time an ice skate blade is to be contoured. The blade depths at the second and third calibration points are measured and the needed pitching is determined. The blade is ground based on the calibration points with some adjustments for the skate wearer's physique and skill level.

Abstract: An improved joint construction for commercial metal doors is disclosed which utilizes a novel force transfer block. The force transfer block has spaced-apart flanges which engage corresponding reglets in a door stile. The inner faces of the flanges bear against the inner walls of the reglets. The flanges of the force transfer block are configured such that they will retain the block on the stile by way of an interference fit with the walls of the reglet. Thus the block does not have to be separately fastened to the stile. A rail abuts the stile and has a recessed portion into which the block is received. A threaded rod extends through the rail and into the stile, and tightening a threaded fastener onto each end of the rod clamps the rail securely between two stiles. The recessed portion of the rail has surfaces bearing snugly against at least two sides of the block such that twisting forces applied to the rail are transferred to the block. Twisting forces transferred to the block from the rail are transferred by the inner faces of the flanges to the inner walls of the reglets.

Abstract: A method of cladding a building wall surface is described with individual prefabricated panels and trim mouldings with any fasteners and joints between the panels and trim being covered on site with a coating of stucco to produce a flush finished stucco surface. Each panel has a uniform transverse cross-sectional profile, and a core of foam material coated with a weatherproof stucco coating on its exterior surface.  Tongue and groove joints are disposed along the longitudinal surfaces and a longitudinal recess in the exterior surface adjacent each tongue and groove joint is adapted to receive a layer of joint coating to fill the recess and cover the longitudinal joints flush with the external surface. The wall surface is installed by cutting the elongate cladding panels to the approximate length of the wall and mounting the cladding panels temporarily to the wall substrate, such as plywood for example. The exterior surface of the panels is aligned to a predetermined outside finish datum and fasteners secure the cladding panels to the substrate without creating a thermally conductive bridge between the substrate and the external ambient atmosphere. The openings around doors and windows, vertical corners and other details are finished by cutting, mounting and affixing elongate transverse end trim mouldings to cover the end surfaces of the cladding panels. Installation is completed by applying a joint coating to cover the joints and filling the adjacent recesses flush with the exterior surface of the panels, then applying a final finish coat to the entire wall assembly.

Abstract: A current sensor for sensing alternating current in a current-carrying conductor includes a substantially C-shaped magnetic core having first and second ends with a gap therebetween. A current sensing element, which includes a microresonant element, is positioned proximate the gap between the first and second ends of the magnetic core such that the element oscillates when exposed to an alternating magnetic field. A biasing coil is attached to the micro-resonant element for carrying a bias current. The micro-resonant element resonates, or vibrates, at a standard oscillating frequency when no current is present in the biasing coil, and resonates at a modified oscillating frequency when current is present in both the biasing coil and the current-carrying conductor.      The magnitude of current in the current-carrying conductor is determined as a multiple of the product of a ratio of the standard oscillating frequency and the modified oscillating frequency, and the bias current.
