Abstract: A footstep for attachment to a bicycle component, such as a front fork, has a channel or semi-cylindrical configuration that encompasses the bicycle component when the footstep is in its retracted position. The combined lateral dimension of component and footstep is barely greater than that of the component itself whereby the footstep is out of the way. The lower end of the footstep is pivoted to the component so that it can be moved outwardly into operative position. Edges of the footstep provide spaced apart lines of contact for great stability. Weight and shock loads are directly and efficiently transmitted to the bicycle component. A small tab facilitates movement of the footstep to operative position by foot manipulation.

Abstract: A tubing connector for connecting lengths of round or square tubing includes a base block with an integrally molded connecting arm. Additional connecting arms are connected to the base block by screws which extend through a hollow bore in the connecting arm and an aperture in an end face of the connecting arm. The screws are threadably received in the base block.

Abstract: Axially adjacent first, second and third carriages are independently rotatable about a common vertical axis. The first carriage supports a plurality of platens which are spaced from the axis of rotation. The second and third carriages have a plurality of mechanisms which support a circumferentially disposed group of silk screen frames, respectively, for selectively pivoting between an inactive position wherein each screen is at an acute angle with respect to horizontal and an active horizontal position wherein the screen selected for printing is brought into contact with a platen on which there is material to be printed. The lowermost group of screen frames are arranged on the second carriage with at least one angular gap between them when they are in their angulated inactive positions.

Abstract: A dock shelter for effecting a seal between the rear end of a truck van and a building to keep out wind and rain comprises a frame having sides and a roof for enclosing the building opening. Flexible, but substantially self-sustaining, foam-filled sealing panels extend toward each other from the left and right inside of a substantially rigid frame to define an opening which is somewhat smaller than the expected width of the van. A partially foam-filled curtain also extends from the top of the frame and behind the left and right side panels. The top curtain has vertically extending stays which augment effecting a seal with the top of the van. The top curtain and the side panels cooperate to maintain the seal when the top corners of the van approach the building opening. The lower ends of the side panels are deflected into sealing relationship with specially shaped flexible foam filler blocks which are located inside of and near the bottom of the frame.

Abstract: Method and apparatus for cutting tenons in the ends of workpieces in which the workpiece is advanced on a rectilinear path, one or more cutting tools are reciprocated on a transverse rectilinear path which intersects the ends of the workpieces and the speed of advance of the workpieces and the speed of reciprocation of the cutting tools are varied so that the cutting tools have an effective undulating cutting path with respect to the workpieces, thus forming a series of spaced tenons thereon.
