  • Patent number: 4007973
    Abstract: A bearing member, for incorporating in a fluid rotary bearing intended for use at speeds in excess of the "half-speed whirl" speed of a solidly mounted bearing, is a solid or composite substantially annular body made of or including material of which the tensile modulus and the specific gravity lie within defined ranges such that while remaining structurally stiff and dimensionally accurate the body is capable of absorbing energy and thus reducing or eliminating vibration and "whirl" in the bearing. The annular member may have radially projecting abutments to serve as sealing means, and these may be resiliently deformable, and may be axially spaced to define a zone communicating with the bearing face of the bearing member thereby to serve as a plenum chamber.

  • Patent number: 3967801
    Abstract: This invention relates to a signal system for high speed vehicles traveling along a predetermined way. In the system vehicles are controlled from the wayside through the use of incremental signals automatically provided to the vehicles as a function of vehicle passage and relative vehicle position. In addition central control is provided for such a system to allow for superimposing on the automatic wayside signal equipment a programmable speed control which allows for simultaneous provision of safe vehicle speed while establishing constant, acceleration or deceleration control over any vehicle in the system.

  • Patent number: 3964756
    Abstract: In a type of ski binding comprising a plate supporting the sole of a shoe of a skier, the end of the plate associated with the tip of the sole being pivoted to the upper surface of a ski about a transverse fulcrum parallel to the upper ski surface, and the other plate end being supported on the upper ski surface by a transverse flange, the shoe is so affixed to the plate that the tip projects forwardly of the associated plate end while the shoe sole portion supporting the ball of the foot of the skier is in substantial vertical alignment with the fulcrum.

  • Patent number: 3963284
    Abstract: A method and apparatus for reducing the friction in a ball-bearing pivot axis assembly. Within the bearing assembly, the balls are floated in a fluid lubricant and, especially in fully-floated units, the weight of the balls is an overriding consideration in the generation of sliding frictional torques. In the present invention these gravitational effects are counteracted by matching as nearly as possible the ball density and the flotation fluid density, the floated weight decrease serving to bring down the friction proportionally with an ultimate theoretical complete reduction of frictional uncertainty from that of known systems.

  • Gib
    Patent number: 3953086
    Abstract: A tapered gib for use in machine tools is composed entirely of a plastic material such as an acetal resin containing uniformly dispersed, finely divided particles of polytetrafluoroethylene so as to provide reduced friction. The surface of the gib in contact with the associated table and positioned between the saddle and the table is formed with raised portions forming the contact surfaces. Various forms of raised surfaces may be used including nibs, ridges and the like. The gib, by virtue of the material of which it is made, fits better, may be operated without lubrication and offers the advantage that it wears relatively slowly and in preference to the metal components with which it is in sliding contact. When worn, the gib may be easily replaced and the new gib easily adjusted since it can be stressed to fit the way in the table with a minimum of deforming creep and short of taking a permanent set by virtue of the compressive forces encountered.

  • Patent number: 3947049
    Abstract: A monoski comprises an elongated body having a central waist portion, an upwardly curved forward tip and an upwardly tapered and outwardly flared tail portion. The monoski has its greatest thickness and minimum width at the central waist portion, and is reduced in thickness both towards the tail portion and the forward tip, the minimum thickness being adjacent the tip. The side edges flare outwardly towards the tip to a ski width, and then the side edges converge to join at the tip proper. The widest region near the tip is hereinafter called the "tip region." Thus, the tip region whose maximum width is about 61/2 inches is wider than the central waist portion, whose maximum width is about 61/4 inches and the tail portion whose maximum width is about 71/3 inches is substantially wider than the tip region. The ski also has a greater-than-normal camber, i.e., 12 - 14 mm (about 43/4-51/2 inches) for a ski of length 90 - 180 cm (about 351/2-727/8 inches).

  • Patent number: 3942725
    Abstract: The present invention is directed to an aerosol spray apparatus comprising two parts which when joined or brought into a sealing engagement cooperate to form a mechanical break up means. The mechanical break up consists of a sprayhead and stem which cooperate to form a swirl forming means which mechanically breaks up pressurized materials being dispensed. The swirl forming means comprises a swirl chamber which is arranged concentrically to a spray orifice, two tangential channels which are directed tangentially into the swirl chamber and two annular channels. The swirl forming chamber and tangential channels are formed by depressions molded into the inner wall surface of the socket of the sprayhead. The two annular channels are formed by depressions molded into the surface of the valve stem. The swirl chamber and tangential channels are covered by a tightly fitted outer wall surface portion of the stem. The tangential channels with the stem form passageways for the pressurized materials.

  • Patent number: 3942449
    Abstract: A self steering vehicle for a transportation system including a roadway having a pair of elongated parallel tracks whose shape in cross-section is domed or convex and preferably having a pair of guide flanges positioned outwardly of the tracks, the vehicle having wheels provided with resilient track-engaging means, such as pneumatic tires, and driving means for propelling the vehicle over the roadway. The wheels of the vehicle tend to follow the tracks because of the deformation of the tires if they tend to move laterally off the center portions of the tracks, and the guide flanges engage the tires, upon the wheels having moved off the tracks because of the imposition of excessive side loads on the vehicle, to turn the wheels back onto the tracks.

  • Patent number: 3942454
    Abstract: The system comprises band anchors uniformly spaced along opposite sides of a flat-decked vehicle, such as a railway flatcar. Each band anchor includes a pair of transversely extending facing channels flush with the deck of the car and having ratchet teeth depending from the top legs of the channels. An anchoring member is adjustably mounted between the channels and has teeth engageable with the ratchet teeth of the channels as tension on the band is taken up. The ratchet teeth cam and retain the anchoring members into engagement with the sides of the load as the bands are under tension. The anchoring members are non-flexible when under no load and each has an outer link with a compression member interposed between the outer link and anchoring member to accommodate extension of the outer link upon longitudinal shifting of the load.

  • Patent number: 3941203
    Abstract: The anti-spinning device comprises for each wheel a sensor delivering electric pulses proportional in number to the peripheral distance covered by the wheel, with a lower number of pulses in the case of a driving wheel, and at least one up/down counter receiving said pulses and co-acting with means for introducing a retard into the ignition system. Said means comprise between the contact breaker and the ignition elements proper a shift register for the breaker signal, a clock adapted to be released by this signal and controlling the successive shifts of the breaker signal in said shift register, and a multiplexer for selecting the original or retarded breaker signal, which is connected to the outputs of said shift register and responsive to a channel selector circuit responsive in turn to the state of said up/down counter. Said device may be applied for protecting against the spinning of driving wheels in a motor vehicle.
