Abstract: An indexing apparatus for indexing an article about an axis. The indexing apparatus is adapted to be removably attached to the article and is constructed to axially displace the article along the axis to a disengaged position upon the initial application of a rotary force to an indexing assembly housed within the indexing apparatus. When in the disengaged position, the article can be selectively rotated about the axis by the further application of rotary force to the indexing assembly so that the article may be positioned in a predetermined angular position. The indexing apparatus further includes locking pins for locking the article in a plurality of predetermined angular positions when the application of rotational force to the indexing assembly is discontinued.

Abstract: A superefficient bicycle frame having a plurality of dual tapered rectangular or square cross section frame members having constant wall thickness. The torsional/bending section modulus of a member is changed by providing a dual taper to the cross section of the frame members so that larger cross sections are used at points of greatest stress and smaller cross sections are used at points of lower stress. The method of manufacture is to cut various two dimensional shapes from sheet stock which are bent along nonparallel bend lines to form the various members. This method of manufacture permits the ends of the section members to be shaped as desired by laser or plasma cutting, or other means, in the flat before bending. The tapered frame members are then connected to form a superefficient frame.

Abstract: A bicycle shock absorber system employs a rubber sleeve trapped between two bushings which are spring loaded so as to increase the force on the rubber sleeve as spring force increases with travel. The rubber sleeve and bushings move with the fork stem which is rigidly attached to the fork and wheel and which slide inside an oil coated steerer tube which in turn rotates inside the outermost head tube which is integral with the bicycle frame. Upper and lower drive flexures permit relative sliding motion but rigidly prevent relative rotary motion so that steering forces are rigidly transferred into the fork stem. The internal elements operate in a bath of heavy oil which coats all the sliding elements providing complete lubrication and the viscous "feel" of a hydraulic shock absorber. Any combination of spring and damping rates may be achieved by changing springs and the oil viscosity. The system is designed to be small and compact enough to fit in a common "oversize" bicycle headtube.

Abstract: A receiver and antenna drive gear unit provide optimal mechanical and electrical pointing of the antenna dish at each of the satellite orbiting in geo-synchronous fashion above the equator, the receiver having the capability of calculating and initially pointing the antenna dish at each of the satellites, and then providing peaking routines under operator control to maximize signal strength. The antenna drive gear unit utilizes a separate motor for each of the azimuth and elevational directions and utilizes circular ring gears and a spur gear to drive the antenna, thereby providing much more accurate and repeatable monitoring and positioning of the antenna unit over extended usage.

Abstract: A system for continuous passive motion of a limb or one or more fingers comprises a reciprocable carriage coupled to a drive belt which is driven by a motor through a disengageable clutch. A second drive belt also driven by the motor, and the first drive belt, carry elements whose positions can be sensed to control limits of motion. Individual finger actuators, adjustable in length and with internal springs, couple engagement means on the fingers to the carriage, which can be driven so as to provide predetermined dwell times at limits of flexion and extension.

Abstract: A rectangular metering member with transversal grooves is located with respect to specially formed apertures in a pressure tube of a hydraulic shock absorber to form orifices communicating between the shock absorber pressure tube and a reservoir. The orifices are adjusted in size automatically to account for hydraulic fluid viscosity changes as a function of temperature by a thermal expansion plug which moves the metering member to increase or decrease the size of the orifices. The metering member is also manually positionable to adjust the size of the orifices for loads of varying mass and velocity. The specially formed apertures in the pressure tube allow the automatic temperature compensation to operate independently of the initial manual adjustment of the metering member.

Abstract: An improvement in braking of the wheels of a bicycle wherein both front and rear wheels are equipped with a coaster brake. Flexible connections are provided between the reaction torque arm of the rear coaster brake and the front brake for applying the front brake. Interposed in the connections is a proportioning lever mechanism for adjustably controlling the amount of braking effect transmitted to the front brake. Flexible connections are provided from the reaction torque arm of the front brake back to the lever mechanism for applying a feedback increment of actuation to the front brake. The system increases the effectiveness of the front brake by taking fuller advantage of the weight transfer which occurs in stopping, and the function of preventing throwing the rider over the handlebars is preserved while the positive feedback increment of control increases the braking effort of the front wheel in proportion to the increased load on the front wheel, which occurs in stopping.
