Abstract: Abstract of the Disclosure A flexible-route transportation system, primarily utilizing privately-owned vehicles to provide ridesharing transportation for the public, is described.  Interactive communications terminals are provided through which drivers of the vehicles may rapidly transmit ride offers via a telecommunications network to a central operations coor-dinating station, equipped with a general purpose program-mable computer. Rider interactive communications terminals, located at public and private facilities, are also connected by the telecommunications network with the central coor-dinating station, permitting eligible members of the public to quickly request rides from one location to another.   The central coordinating station matches the ride requests with the ride offers, on a trip-by-trip basis, comparing the driver's indicated origin, destination, seating requirements and time with the rider's requested origin, destination, seat availability and time.  If a ride offer and ride request can be matched within reasonable limits of space and time, the central coordinating station transmits to the driver the rider's identity and location and transmits to the rider the description and identity of the vehicle, so that the driver can pick up and drop off the rider en route to his or her destination.  The system includes security features for preventing unauthorized access to the system by either drivers or riders, accounting features for properly billing riders and reimbursing vehicle owners for transportation services, and special terminals for entering trip information quickly and accurately.

A second version of the wheel fixing structure includes a pair of shoes which are assembled along a rail at longitudinally spaced locations for receiving and properly locating the bicycle wheels, and clamping assemblies which clampingly retain the wheels within the shoes.  A third version of the wheel fixing structure includes a pair of shoes which are attached to a longitudinal channel carried by the utility bars for receiving and properly locating the bicycle wheels, and clamping as-semblies which clampingly retain the wheels within the shoes.  Optional shoes to accommodate smaller bicycles may also be attached to the chan-nels or the shoes may be adjustably attached to accommodate various sizes of bicycles.

Abstract: ABSTRACT OF THE DISCLOSURE          In accordance with a new method of casting electrode grids for electric lead storage batteries in a mold, premature solidifying of the melt is prevented before the end of the mold filling period by an additional heating pulse applied to the melt during the mold filling process, as well as by the use of a good heat conducting mold material.  The cooling down to the unmolding temperature is also accelerated.   Because of the short dwell time of the lead within the mold, there simul-taneously results a short machine cycling period.  The separate pulse heating of the melt is preferably carried out by an in-duction heating apparatus, the alternating field of the in-ductor located within the mold walls producing heat through eddy current production within the molten molded body.

Abstract: ABSTRACT            An anchor nut fastener device is of the type comprising a tubular body portion (11) and an externally tapered nut portion (12) the narrow end of which adjoins one end of the body portion, whereby when the body portion is inserted in a suitable hole in a workpiece and the nut portion (12) is forced into the body portion (11), the externally tapered nut portion (12) both radially expands the body portion into engagement with the wall of the workpiece hole and also engages the nut portion in the body portion, thereby to provide an anchor nut in the workpiece.  The externally tapered nut portion (12) comprises a first, relatively long, part (24) of a relatively shallow taper end and a second, relatively short, part (26) of relatively steep taper further away from the body portion than is the first part and extending radially outwardly of the first part.  The end of the body portion (11) is enlarged to provide a head (10) with a countersink (14).  The countersink provides a space into which the leading narrow end of the externally tapered nut portion can be enlarged when the nut portion (12) has been forced completely into the body portion (11).  It is an advantage of this anchor nut fastener device that the diameter of the hole in the workpiece can be the same regardless of the workpiece thickness over a wide range with the size of the fastener being the same, whereas with prior fasteners the diameter of the hole in the workpiece requires to be related to the workpiece thickness.
