Abstract: A rotatable illuminated game board system to adapt to contemporary board games or for use with newly-conceived games, the system including stained glass elements adhered to a translucent plate beneath a modified printed sheet of game instructions and rules, all atop a quadrilateral housing attached to a stationary platform by means of a Lazy Susan type bearing allowing rotatability, said housing containing a switchable electric light source that permeates the stained glass elements and accentuates such areas on the playing surface that are important to the game's strategy or esthetic quality.

Abstract: A dynamic system for making use of an exercise bicycle supported on front and rear struts, the system permitting the bicycle to sway side to side when ridden vigorously, the system including a first and a second housing for resting on a support surface, a platform retained by each housing, the platform of the first housing serving to receive thereon the bicycle front strut and the platform of the second housing serving to receive thereon the bicycle rear strut, each platform being pivotal end to end and at least one deflectable resilient member engaging each platform and functioning to normally retain the exercise bicycle uprightly.

Abstract: A device for use with a flexible bag in order to hold the bag open for facilitating access to the interior thereof, and comprising a body having a normal substantially flat planar configuration and sufficiently flexible for responding to pressure thereagainst for deforming into a substantially cylindrical configuration, one cylindrical configuration thereof being of a diametric size smaller than the diametric size of the bag for facilitating insertion of the body into the interior of the bag, and the body having sufficient memory characteristics for springing radially outwardly from the one cylindrical configuration for restriction by the sidewall of the bag whereby the bag is retained in a fully open position, the body being responsive to the release of pressure thereagainst for returning to the normal flat planar configuration thereof.

Abstract: A sphere launching apparatus for selectively admitting spheres into a pipeline and comprising an angularly disposed support or track for storing a plurality of the spheres thereon, an access port at one end of the track for receiving the spheres therethrough for disposition onto the track, a discharge port at the opposite end of the track for discharging the spheres therefrom and injecting the spheres into the pipeline, the support member being interposed between the access port and discharge port for supporting the spheres in two parallel but offset substantially sequential relationship upon the track, and a release mechanism extending into the proximity of the support or track for alternate engagement with the leading sphere of each of the two parallel sequences thereof for releasing a single sphere at a time for passage through the discharge port for injection into the pipeline.

Abstract: A stuffing gland for shafts subject to relatively high pressures acting thereon in one longitudinal direction and comprising a flange disposed around the outer periphery of the shaft and having one side thereof open to the high pressure acting on the shaft, the flange being connected with the shaft for transmitting the force created by the pressure acting thereon to the shaft ina longitudinal direction opposed to the action of the high pressure surrounding the shaft, the area of the flange open to the high pressure being equal to the cross sectional area of the shaft for balancing the forces acting of the shaft for ease of operation of the shaft.

Abstract: A stuffing gland for shafts subject to relatively high pressures and comprising a collar disposed around the outer periphery of the stem and having one side thereof open to the high pressure acting on the stem, a passageway communicating the high pressure from the one side of the collar to the opposite side thereof for applying an equal and opposite force against the collar for equalization of the pressures acting on the shaft whereby the shaft may be freely rotated about its own longitudinal axis.
