Abstract:
In the disclosed apparatus, a web of material is fed from a supply roll, around a plurality of idler rollers, and past a series of blades which slit the web into a plurality of strips. Adjacent strips are rewound about corresponding product cores on different ones of a pair of takeup rollers in alternating fashion. Controls are provided for independently varying the amount of current supplied to first and second electric motors which drive the takeup rollers and supply roll respectively. The amount of slippage of the product cores relative to the takeup rollers can be adjusted by a clutch mechanism. According to the disclosed method, the takeup rollers are first brought up to full operating speed. The speed of the supply roll is gradually increased to feed the web to the product cores so that they rotate at approximately eighty percent of the speed of the takeup rollers throughout the rewinding operation. Product rolls with uniformly aligned edges and without high spots or material distortion are produced.
Abstract:
An improved multi-fuel supply and co-injection system and method for powering internal combustion and turbine engines, whereby various combinations of fuels, both liquid and gaseous, may be mixed together and fed into the system, under the real-time control of a microprocessor responding to a variety of sensors and acting on a variety of control devices, all working together in a manner designed to enhance the utilization of the thermal content of the various fuels, and in particular to enhance the combustion efficiency and increase the power output while decreasing the consumption of fuel, calculated both by quantity and by cost and whereby the liquid fuel lubricates the moving parts of the injection system.
Abstract:
An air compression apparatus has a frame, a tank, and a motor. A drive mechanism is operably connected to the motor and at least one piston assembly is >@5rablC connected to the drive mechanism and configured to move within a respective cylinder mounted to the frame. The piston assembly includes: (1) a piston body; (2) a piston rod having a hollow bore connected at one end to the drive mechanism and at an opposite end to the piston body; and (3) a piston valve installed on the piston body. In use, upward travel of the piston body as caused by the drive mechanism acting through the piston rod opens the piston valve and allows ambient air to be drawn through the hollow bore into the cylinder, and downward travel of the piston body closes the piston valve so as to compress the air within the cylinder.
Abstract:
A shock absorbing bicycle wheel hub apparatus uses an open ended, cylindrical shock absorber housing (10) mounted concentrically within a wheel hub (1). The wheel hub (1) is adapted for rotation about the shock absorber housing (10). A pivot rod (7) is axially aligned with the shock absorber housing (10) and rotationally mounted within its sidewall (8). Terminal ends (11) of the pivot rod (7) engage cover plates (9) fixedly mounted thereon. A pressure tube (7') is axially aligned with the shock absorber housing (10) and extends through it so that its terminal ends (12) may be fixed in the cover plates (9). A shock-absorbing medium (5) is compressively positioned between the pressure tube (7') and an interior surface (10') of the shock absorber housing (10). The cover plates (9) engage a bicycle fork (14) so that weight supported by the bicycle fork (14) is transmitted through the cover plates (9) and the pressure tube (7') to the shock absorbing medium (5), and thereby, through the shock absorber housing (10) and the wheel hub (1) to a wheel of the bicycle. Likewise, road shocks are transmitted through the shock-absorbing medium (5).
Abstract:
An outer wheel, tire and rim, is mounted onto an inner wheel or hub (20) and is adapted for low friction rotation on the hub. An arm (40) is pivotally attached to the inner wheel and carries a receiver for the axle (60) upon which the wheel is mounted so that the axle is positioned over an arc of rotation about the pivot point of the arm. The arm is biased by an elastomeric body (70) so that as the arm moves over its arc of rotation, the elastomeric body is compressed. As the wheel rotates under load, road shocks are transferred to the biasing device which acts as a shock absorber.

Abstract:
The invention pertains to a bus stop shelter (2) comprising an elongated canopy (4) forming an overhead roof for the bus stop shelter, and at least two wall sections (6, 8). The canopy and wall sections are supported by a framework (16) mounted on a sidewalk, and the canopy and wall sections define a partially enclosed covered space providing shade and shelter for people within said partially enclosed covered space. The canopy comprises a biocomposite material. Preferably, also the supporting frame comprises a biocomposite material. The invention also pertains to a method of manufacturing such a canopy and/or parts of the framework from biocomposite material.
