The saddle has a broad rear section, a narrow front section and a frame and saddle cover. To make the saddle more comfortable and prevent injury to the cyclist, the front section can be slid, facing rear section downward and forward against a pre-stress.

A completely frequency adjustable decoder and encoder circuit in a continuous tone coded squelch system of mobile radio is made possible through the use of a new null network. This filter network is characterized by the placement of field effect transistors or other isolation devices between phase shifting portions of the network. All the requirements of frequency stability, small standard components, immunity to mechanical shock, and low cost are simultaneously possible in this decoder-encoder ...

An anatomical multilayer seat for use on a bicycle or the like. The seat comprises a formed substantially rigid shell covered by a flexible cover sheet and having a layer of soft encapsulated gel material provided between the cover sheet and the seat shell. The encapsulated gel layer is constrained against any appreciable lateral movement while permitting only limited deflection of the gel during use by a lower formed foam layer provided between the shell and the cover sheet to produce a control...

A lightweight molded protective helmet for use by cyclists and preferably produced by stretch-blow molding a moldable plastic material. The helmet includes outer and inner shells or surfaces each having a plurailty of openings therein, with the surfaces being connected together by walls of the openings formed integral with the surfaces of the helmet. The openings in the helmet surfaces can have any shape such as circular or elongated, and can be made substantially perpendicular or inclined to th...

An improved sole structure for attachment to a shoe for bicyclists. The sole structure includes a conformed rigid body having in the front region a plurality of recessed seats each containing a fastener for attachment to a plate anchoring the sole structure to a bicycle pedal, and also includes in the plantar arch region a recessed seat containing a bolt fastened to a plate provided on the sole lower side, the plate being connected to a strap for attaching the sole structure securely onto a foot...

A lighting fixture adapted for uniformly illuminating a wall surface by utilizing an asymmetric light reflection pattern. The fixture includes a support housing and an elongated concave-shaped reflector which is pivotably attached to the support housing and has multiple facet surfaces arranged for reflecting light from the centrally located light source out through a front opening, which is covered with an ultraviolet filtering glass diffusion plate. The reflector has major rear and minor front ...

An anatommical multilayer seat for use on a bicycle or the like. The seat comprises a formed substantially rigid shell covered by a flexible cover sheet and having a layer of soft encapsulated gel material provided between the cover sheet and the seat shell. The encapsulated gel layer is constrained against any appreciable lateral movement while permitting only limited deflection of the gel during use by a lower formed foam layer provided between the shell and the cover sheet to produce a contro...

A facsimile reproduction system is disclosed. The system utilizes a laser beam at the transmission station to scan across an image to be reproduced through an acousto-optic modulator (AOM) cell. The laser beam is reflected off the image onto photo detector cells to generate electrical signals analogous to tonal variation in the image. A laser beam at the receiver station is also provided to sensitize a sheet of sensitized paper to produce a facsimile of the image. The intensity of the receiving ...

A bicycle chain cleaning or lubricating device and method adapted for cleaning or lubricating bicycle chains in place without need for their removal and replacement. The device comprises a receptacle for enclosing a portion of a bicycle chain to be cleaned or lubricated and for containing a quantity of solvent or lubricant and a mating cover for the receptacle. The cover contains at least one rotatable sprocket brush having spaced-apart bristle tufts on its periphery and sized to fit closely int...

The invention is directed to a protective helmet comprising a formed plastic foam shell having an internal plastic infrastructure embedded at least partially therein. The embedded infrastructure provides increased shock absorption characteristics for a wearer during use. The helmet can also include either a thin plastic outer microshell or a thicker relatively rigid plastic outer shell, with a padding material attached to the inner surface of the reinforced foam shell, and a retention strap atta...
