Abstract: An improved guard rail system spacer block having a front face, a rear face and an outer circumferential undulating surface surrounding a plurality of individual spaced apart cavities that extend from one of such faces to the other. Lugs project from the rear face to support the block on a post of a roadway guard rail system and align it with the post during installation of the system and a lug projects from the front face to temporarily support a guard rail strip during installation of the guard rail system.

Abstract: A block used to space guardrails from support posts. The positioning or spacer block is a generally rectangular block having corded-out cavities to reduce weight and tabs or projections for cooperatively engaging the sides and top of a support post as well as the edges of the guardrail during roadway safety barrier system installation. Webbing within one or more of the cavities is used for additional structural support. The spacer block may be formed by low-pressure injection molding to optimize the strength to weight characteristics of the spacer block. The spacer block is formed from virgin and/or recycled plastic material and/or includes virgin or recycled rubber material, such as that obtained from the regrind of used tires, and/or another elastomeric materials from other sources.

Abstract: The guard rail support attachment and positioning block or spacer block is used to space guard railing away from posts such as “I” beams which are driven into the ground. The spacer block keeps automobile wheels from impacting the I beams and initiating a roll of the vehicle. The spacer block is a generally rectangular block or cube including corded-out cavities to reduce weight and tabs or projections which cooperatively engage the side of the post and the edge of the guard rail to position and hold same in position for attachment with holding members such as bolts. Webbing can be used to provide structural support within the cavity. The spacer block may be formed by low pressure injection molding to form a structural foam spacer block to optimize the strength to weight characteristics of the spacer block.

Abstract: An exercise device is provided which includes a surface for supporting a body of a user and a frame for supporting the surface above a floor. Mechanism(s) may be provided for changing the orientation of the surface relative to the floor during an exercise routine. Resistance device(s) are connected to the device for providing resistance to movement of the user. Display device(s) may be provided to display various information relating to an exercise routine to the user and to others. Computer control(s) may be included for controlling the amount of resistance provided by the resistance devices and for controlling the orientation of the support surface relative to the floor. Memory device(s) may be associated with the computer control for storing exercise routines, recording the results of performed exercise routines and other information.
