Abstract: A mirror for viewing the face at different magnifications selectable by the user includes a first, oval primary mirror comprised of a front mirror plate having a first magnification and a rear mirror plate concavely curved to provide a second, greater magnification, the front and rear primary mirror plates being held in a back-to-back arrangement within a bezel ring. The ring is pivotably supported within a yoke attached to the upper end of a stanchion which protrudes upwardly from a base, allowing the primary mirror to be pivoted about a horizontally disposed minor axis of the primary mirror, or about a vertical axis through the stanchion, thus presenting either the front or rear reflecting surface to a person located in front of the mirror.
Abstract: A cable reel lifter/transporter apparatus for elevating a heavy cable reel above a surface to permit free rotation of the reel, thereby allowing cable or tubing to be payed off the reel, and for manually transporting cable reels includes a pair of L-shaped planar frames each having a long straight handlebar arm and a relatively short straight leg which depends perpendicularly downwards from a lower surface of the handlebar, near a front transverse end thereof, each leg having at the lower end thereof a short tubular foot. A tubular bearing support protruding upwards from each handlebar rotatably supports opposite ends of a horizontal cable reel support shaft. A pair of arbors slidable on the shaft have inner tapered portions insertable into a separate spindle hole in each of two disk-shaped end plates of a cable reel, and subsequently secured to the shaft to hold the shaft and cable reel in a fixed position between the frames.
Abstract: A golf putter is provided in which the lie and/or loft angle thereof may be semi-permanently but reversibly adjusted by a golfer prior to playing, to suit the individual golfer's stance, swing dynamics, playing skill and/or condition of the greens on which the golfer intends to play. An adjustable lie/loft angle putter according to the present invention includes a hollow tubular shaft and a head coupled together by a reversibly bendable coupling element which preferably is fabricated from a relatively ductile metal such as stainless steel which is formed into an elongated, hollow tube which has a circular cross section. A first, upper longitudinal end of the coupling element is insertably received in the lower opening of a bore within the shaft, while the other end of the coupling element is attached directly to the putter head or to a hosel protruding from the head.

Abstract: A golf putter which aids a golfer in aiming a putt and avoiding twisting of the shaft in the hand during a swing includes a head provided with a pair of laterally spaced apart trailing members which protrude rearwardly of the rear surface of the head and function cooperatively as weighting/aiming members. The trailing members are preferably located equidistant from a vertical center plane through the sweet spot of the head and have in plan view longitudinally directed visual features perpendicular to the front ball-impacting face of the head, which assist a golfer in visually framing an intended initial ball trajectory to a target hole on a golf green, along with a ball impact vector perpendicular to the center of percussion or sweet spot of the head. Each of the trailing members is preferably laterally symmetric, and may include a longitudinal index line marked on the upper surface of the member, to facilitate visual framing of a putt.

Abstract: A mirror ideally suited for use in a shower enclosure, bathroom or other high humidity environment is adjustable by a user to provide a magnification increasable from unity to three times or more, as well as being resistant to condensation fogging of viewing surfaces thereof. A fogless adjustable magnification mirror according to the present invention includes a ring-shaped frame which holds within an inner peripheral wall surface thereof a clear front viewing window and a rear flexible mirror plate or diaphragm having a reflective surface and a circular shape. The viewing window and mirror plate are held within the frame in a fluid pressure-tight seal, and form therebetween a sealed hollow cylindrically-shaped interior space or plenum bordered on a peripheral longitudinal surface thereof by the inner annular surface of the frame.
Abstract: A golf putter in which both the tactile response and ball launching characteristics may be independently varied over relatively wide respective ranges includes a head in the face of which is formed a stepped cross-section cutout portion which receives a stepped cross-section insert. The putter head includes an outer insert lamination which fits into a complementarity-shaped front recessed portion of the cutout, the outer lamination having an outer generally flat face flush with the front face of the head. Inwards of the recessed portion of the cutout in the front face of the putter head is a pocket adapted to receive and enclose from exterior exposure an inner insert lamination.
Abstract: A method and apparatus for measuring pressures exerted on human feet or horses' hooves comprises a rectangular array of piezoresistive force sensors encapsulated in a thin polymer package that is inserted into a shoe, or incorporated into a sock that may be pulled over a foot or hoof. The preferred embodiment employs novel piezoresistive normal force or pressure sensing elements which include a polymer fabric mesh impregnated with conductive particles suspended in an elastomeric vehicle, preferably silicone rubber. The piezoresistive mesh layer is sandwiched between an array of row and column conductor strip laminations, preferably made of a nylon mesh impregnated with printed metallic paths. In a variation of the basic embodiment, each normal force sensor element is bordered by laterally and longitudinally disposed pairs of shear force sensor elements, each of the latter comprising a pair of adjacent resilient piezoresistive pads that have longitudinally contacting lateral surfaces.
Abstract: A method for making air turning vanes each having formed therein a pair of locking protuberances which adapt the vanes to self-gripping attachment between a pair of rails to fabricate an air turning vane and rail assembly utilizes an elongated length of double plate airfoil vane stock including a front plate having an outer concave surface arcuately bowed about the central longitudinal axis of the plate, and a rear plate having an outer concave surface arcuately bowed about the central longitudinal axis of the rear plate. A vane of a desired length is severed from the vane stock, and the outer concave surface of the rear vane plate is impacted by a punch with sufficient force to deform from the inner surface of the plate a generally hemispherically-shaped button having a lower severed wall which forms a locking lip. The apparatus according to the present invention includes a guillotine-like shearing structure/vane stock support fixture which vertically slidably supports shear blade.
