Abstract: The present invention relates to increasing the ability of a golfer to excel at the game. The invention comprises a correlated set of golf clubs in which each club of the set is dynamically correlated with every other club of the set so that each club has approximately the same overall mass, first moment about some wristcock axis, and second moment about the same axis. This correlation is achieved using a unique computation method for determining the mass distribution for each club of the set which distributes the mass of the club among its various elements, such as the club head, an added mass rigidly secured in the shaft at the midpoint between the center of mass of the club head and the wristcock axis at the grip, and a further mass positioned adjacent the wristcock axis.

Abstract: A calibration circuit and method for instructing an instrument operator on how to adjust the brightness and contrast controls of a video display in order to achieve a precise display intensity directly proportional to the video drive signal input to the video display. A photometer detects the display intensity as the video drive is modulated and a differential amplifier compares the video drive to the photometer output signal thereby generating an analog offset signal highly representative of brightness and contrast offsets. The analog offset signal is converted to numerical offset values from which independent brightness and contrast offsets are computed. For raster-scanned video displays only a one-bit analog-to-digital converter, a comparator, is required and a multi-bit numerical value of the video offset may be obtained from the comparator output by the method of counting the number of scan lines in each frame giving a positive comparator output.

Abstract: A vise clamp has an elongated body which fits into a T-shaped slot of a tool table. The body has a head at one end which extends out of the slot and pair of pivotal lugs which fit under the side shoulder of the slot. Means are provided to provide a pivoting action which tends to pivot the head toward the table surface to tend to clamp a tool such as a vise against the table. The major portion of the clamp thus remains recessed below the table surface. The clamp permits making a low profile swivel base vise that has the clamps positioned below the vise base and yet they are easily operated.

Abstract: A nine position air pressure regulator includes a main regulator body member having an unregulated first pressure cavity, a regulated second pressure cavity and a valve seat between the cavities. A diaphragm is in sealing relationship to the second cavity, and the first end of a pressure regulation spring presses against the diaphragm to tend to force it into the second cavity. The spring operates inside of a cylinder, and a yoke is located at the second end of the spring away from the diaphragm. A rotor ring is rotatably mounted with respect to the main body member and threadably mounts a plurality of pairs of cap screw stops. The stops of each pair of screw stops are spaced 180.degree. apart from each other around the rotor and are adjusted to terminate at the same distance from the rotor bottom. By rotating the rotor ring, any desired pair of screw stops can be vertically aligned under the outer ends of the yoke.

The wall phone is mounted on the mounting posts and connected to the jack.

Abstract: A rocking chair of the type employing a flexure member formed of a flat, fiber reinforced material for supporting a chair seat with respect to a chair base in which the support means for supporting the flexible sheet member from the chair base has a flat surface to which the sheet member is secured and an aperture above the flat surface through which the sheet member extends, the opposed walls of the aperture diverging from top to bottom to allow flexing of the sheet member with the effective length of the flexure member decreasing as the chair is rocked rearwardly. The sheet member is preferably disposed at an angle to the vertical of between five and fifteen degrees, to impart an initial bias on the sheet member. The rear wall of the aperture is curved to allow a greater length of the sheet member to flex as the chair is rocked rearwardly.

Abstract: A retaining mechanism securely retains a gear in a fixed position on a shaft of a drive system in a photographic processor. The retaining mechanism includes a woodruff key which is held in position between the gear, preferably in a keyway in the gear, and an arcuate keyway in the shaft. The key has a first end portion which is engaged by a set screw and a second end portion which deformably engages an interior surface of the keyway of the gear. The set screw extends through a bore in the gear and has a head portion with a diameter slightly greater than the diameter of the bore. The set screw engages the first end portion of the key with its distal end, thereby tipping the key so that the second end portion of the key engages the interior surface of the keyway of the gear.

Abstract: A railroad dump car, such as a side dump rail car, uses hydraulic actuators to tilt the dump body to permit unloading of the contents of the dump body. A hydraulic booster pump is connected to the auxiliary air supply of the train. The booster pump converts the relatively low pressure (about 90 psi) air to a high hydraulic pressure (about 3000 psi). In another embodiment, a bidirectional rotary pump driven from the rail car axle pumps the hydraulic fluid. The booster pump (or the bidirectional rotary pump) pumps hydraulic fluid from a hydraulic reservoir to a hydraulic accumulator, which receives the hydraulic fluid and stores the hydraulic fluid under pressure. When the hydraulic accumulator is fully charged, the operator triggers a valve to cause dumping. The valve causes the hydraulic accumulator means to supply the pressurized hydraulic fluid to the hydraulic actuators, which pivot the dump body with respect to the car frame to unload the contents of the dump body.

Abstract: In a house structure in which insulated material is placed between and over attic floor joists, an insulation vent provides an air channel to allow free flow of ventilating air along the underside of roof sheathing between the exterior soffit and the interior of the attic above the insulating material. The vent is molded of one piece of expanded polystyrene. The vent has a base with longitudinal ribs, a pair of walls extending upward at an angle, and a pair of flanges extending outward from the edge of the wall, for attachment to the roof joists. The cross section of the vent is generally U-shaped. The vent is installed by flexing the walls inward, inserting the vent between a pair of roof joists and against the roof sheathing, and releasing the walls. The walls expand, pushing the flanges against a pair of roof joists. Friction holds the vent in place. The center of the U forms a channel for the passage of air.

Abstract: A ratchet wrench includes a body which carries a shank adapted to be removably fitted into a socket head for the purpose of rotating a socket head to turn a nut in the socket onto or off of a bolt. A handle pivot pin is mounted on the wrench body at a side opposite the shank to have its axis parallel to and spaced from the axis of the shank. An elongated wrench handle is mounted on the pivot pin and is movable with respect to the wrench body between a first position wherein the handle fits into the wrench body and is thus locked with respect to angular movement between the wrench body and the handle and a second position where it is above and spaced from the wrench body and can rotate freely about the pivot pin to cause the wrench body to rotate freely about the axis of the shank.
