Abstract: Belt Drive Systems for Bicycles Abstract A bicycle has a belt (1600) and pulleys (1400, 1500) in place of the usual chain and sprockets. Each pulley (1400, 1500) has three (more or less) raceways (1400a, 1400b, 1400c, 1500a, 1500b, 1500c) that have openings (1430) that permit the belt (1600) to be shifted.  A rotatable arm (1800) pivoted to the frame (1000) of the bicycle controls the shifting of the belt (1600) to the desired raceway.  One end of the arm (1800) applies lateral pressure to the belt (1600) just before it arrives at the pulley (1400) associated with the driving pedals (1300) of the bicycle, to shift raceways of the driving pulley (1400).  Similarly the other end of the arm (1800) applies lateral pressure to the belt (1600) just before it enters the driven pulley (1500) to shift raceways of that pulley (1500).  Each end of the arm (1800) is biased by a main spring (1810) to apply vertical pressure to the belt (1600) to maintain it tight.

Abstract: Apparatus for installing cables with a certain stiffness, more in particular glass fibre cables, into a duct (6, 24) of a channelization system, using the working of a compressed gas, which apparatus is adapted to exert pushing forces on a cable (26) being introduced in order to support the compressed gas working on the cable in the duct. The apparatus comprises cable advancing means and gas inserting means. The cable advancing means include a hollow, substantially rectilinear cable lead-through channel (3) with an entrance end (4) and an exit end (5), at least one pair of wheels (8, 10; 9, 11) mounted opposite to each other for moving on a cable (26) disposed between these wheels into the direction of the outlet end (21) of the duct (6), and a pneumatic motor (15) coupled to at least one of said wheels for providing a driving couple to it. At least one of the wheels is coupled to a pneumatic piston/cylinder combination (13, 14), in such a way that when compressed gas is supplied to the pneumatic cylinder (14), transverse forces will be exerted on the cable (26) disposed between the wheels (8, 10; 9, 11). The gas inserting means include a gas channel (7), which debouches into the cable lead-through channel (3) and which is adapted for inserting compressed gas into the lead-through channel (3) between the wheels and the exit end (5) of the lead-through channel (3). The motor (15) is capable of providing a driving couple, which is larger than the driving couple, which has to act on the cable (26) to compensate a pressure difference existing at the inlet end of the duct between the pressure inside and the pressure outside the cable lead-through channel (3) as a consequence of inserting the compressed gas via the gas channel (7) into the cable lead-through channel (3). The pushing forces are exerted by the wheels on the cable (26) as a consequence of the cooperative effect of the driving couple and the transverse forces. The gas channel (7), the pneumatic motor (15) and the piston/cylinder combination may be coupled to the same compressor. For use in a tandem arrangement the apparatus comprises further a coupling unit (18) to be coupled to an outlet end (21) of a preceding duct section (24), and which includes a mainly hollow housing (19), an outlet pipe (23) for diverting a flow of gas, which may leave the outlet end (21) of the duct section (24), and an outlet opening (22) through which a cable may be led into the direction of the entrance end (4) of the cable lead-through channel (3). Advantages: the exerted transverse forces are very acurately adjustable and substantially constant; the apparatus is non-destructive to the cable when cable introduction is slowing down or stagnates; in a tandem arrangement the apparatus needs hardly any human interference and is safe for the operating staff. <IMAGE>

Abstract: The present invention relates to a method for comminuting a coarse lump mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction is determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process. The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value fo the mill in question, and determined with respect to a selected degree of grinding.The grinding efficiency of autogenous primary grinding mills is greatly improved by means of the invention (Figure 4).

Abstract: A thermoplastic synthetic high polymer sheet including induced tensile stress lengthwise of the sheet which varies in intensity from a maximum along one edge to a minimum along the other edge. The induced tensile stress is frozen in the sheet by maintaining its temperature below a transformation temperature. Upon elevation of the temperature of the sheet above the transformation temperature, as the process of fabrication of a laminated windshield is to commence, the sheet, without further operative forming operations, will deform to conform substantially to the outline of the outer curved lamina of the windshield. The sheet may include a zone along one edge to provide filtering of glare.

Abstract: A roller construction is described for use in glass bending apparatus employing an array of curved rods. A tubular sheath is rotatably mounted on a curved rod. The sheath comprises a tubular metal winding that is coaxial with the rod and a coaxial metal meshing adjacent either the inner or outer surface of the winding. Such a sheath provides both good torsional resistance and flexibility in the axial direction. When an array of such curved rods is used to define a cylindrical surface in glass bending apparatus, heated glass sheets may be bent on such array to conform their curvature to the surface defined by the rods.

Abstract: A transient electromagnetic method for detecting irregularities on container walls by measuring wall thickness. The method utilizes a transmitting antenna and separate receiving antennas so as to form a loop-loop configuration. The transmitting antenna induces current into the container wall and the receiving antennas detect the induced current and produce received signals. The distance between the antennas and the container wall can vary, particularly where insulation is interposed therebetween. The variations in antenna distance affects the received signals. The affects are corrected by determining the maximum of the respective received signal and determining the arrival time of the maximum. The maximum and the arrival time are used to determine the thickness of the wall.

Granted: 1993-10-05
Abstract: ABSTRACT OF THE INVENTION This invention relates to a flapper check valve having a valve housing which has at least one outlet opening.  A valve backer plate having a plurality of arcuate backer through holes is positioned generally parallel to a valve port plate having a plurality of arcuate port through holes. The valve port plate and valve backer plate are sealably secured with respect to the valve housing.  In an open position of the flapper check valve, the backer through holes are in communication with the port through holes.  At least one peripheral spacer/hermetic seal is positioned at a generally peripheral location relative to the valve port plate.  Upon combustion within the combustion chamber, the flapper check valve prevents fluid/gas backflow in a direction from the valve backer plate to the valve port plate.  At least one flat central spacer is positioned at a generally central location relative to the valve port plate and the valve backer plate.  A plurality of inner spacer/guide pins are positioned on an interior surface of the valve port plate.  The inner spacer/guide pins provide sufficient support to the valve backer plate whereby the valve backer plate can have a reduced thickness and still resist deflection when the valve backer plate is subjected to relatively high pressures from within the valve housing during a combustion cycle within the combustion chamber.
