Abstract: A rotational control apparatus (A) having a rotatable input (26 or 180) and output (26 or 180) with respective interface discs (106, 180). Three sets of two diametrically opposed pistons (64 and 66, 68 and 70, 72 and 74) are controllable to rotatably relate the interface discs (106, 180). The piston sets (64 and 66, 68 and 70, 72 and 74) include piston heads (76) with dissimilar diameters such that each of the sets of pistons (64 and 66, 68 and 70, 72 and 74) may apply a dissimilar torque for a given amount of air pressure. Each of the piston sets (64 and 66, 68 and 70, 72 and 74) may be actuated independently or in combination with each of the other sets of pistons (64 and 66, 68 and 70, 72 and 74) such that the interface discs (106, 180) may be rotatably related to each other with varying degrees of torque.

Abstract: A framing system (10) is disclosed including three-dimensional structural members (12, 14) formed from planar panels (16) having their edges removably secured together by provisions (48) including slide connectors (66, 174) which receive lugs (52) slideably received in and abutting with latches (56).

Relative rotation is prevented between the clamp (28) and the structural members (12, 14) by detents (44) formed in the clamp (28) which are received in notches (26) formed in the free face (25) of the tubes (24).

Abstract: Apparatus (10) is disclosed including first and second supports (24) for supporting a stationary bicycle, with the supports (24) secured at adjustable longitudinal locations between first and second longitudinal rails (12). Cords (50) having grips (52, 54) on the opposite ends thereof are adjustably and slideably secured intermediate their ends at any location intermediate the ends of the longitudinal rails (12) by pivotable cam devices (60, 160) slideable and pivotable in upper channels of the rails (12). Additionally, the pivotable cam devices (60, 160) allow the lengths of the ends of the cords (50) to be adjusted relative to the rails (12). Thus, while pedaling and/or supported on the stationary bicycle, the user can exercise his upper body by stretching the cords (50) extending at various angles from locations in front, behind, and vertically below the user and with the desired tension depending upon the length of the cords (50) relative to the rails (12).

Abstract: A rotary switch with three controlling positions in a circulating sequence of "Off", a small output, and a large output, includes a cover and a base connected with the cover. A rotor which is made of an electrically insulating material and provided with three cam parts along its circumferential periphery, is mounted in the base to rotate an electrically conductive plate with two side portions engaged with two of the cam parts. A first, second and third leaf spring respectively has a fixed end connected with an input wire, an input end of a diode, and an output wire of the switch and a free end extending toward the rotor. The fixed end of the third leaf spring is also connected with an output end of the diode. When the switch is set to the "Off" position, the first leaf spring contacts with the rotor, and the other two leaf springs contact with the conductive plate via the two side portions thereof.

Abstract: A gearshift lock is used to prevent a gearshift from moving with respect to a gearshift seat from which the gearshift extends. The gearshift lock includes a locking box firmly attached on the gearshift seat and includes two passages therein. Two first springs each are respectively received in a corresponding one of the passages of the locking box. A U-shaped latch includes a curved rod and two prongs each of which is received in a corresponding passage of the locking box. A motor is positioned in the locking box and includes a toothed rotor head. A spring-biased engaging device is positioned in the locking box and engaged to the two prongs of the U-shaped latch thus limiting the two prongs of the U-shaped latch in the passages of the locking box and the curved rod of the U-shaped latch enclosing the gearshift thus preventing the gearshift from being moved. A control circuit functions to drive the motor in response to a reception of an effective control signal from a remote control.

Abstract: A roller bushing assembly for use in a vehicular leaf spring suspension system pivotally supports an end of a leaf spring so as to minimize transmission of roadway induced shock and vibration loads to the vehicle and driver. The roller bushing assembly includes a tubular housing containing roller bearings for support of a shaft which is connected to a vehicle chassis. Free flexure of the spring is facilitated by providing low friction pin connections that minimize resistance of the vehicle/spring connections to rotation of the spring ends and extension and contraction of the spring. A method of installation of a bushing having bearings therein includes supporting the bearings on a pilot and force-fitting the tubular housing into a spring eye with a pressing tool. After removal of the pilot from the bearings, the shaft is inserted into the bearings and seals are slid along the shaft to abut and seal the bearings against intrusion of foreign matter.

Bolts (52) extend through an aperture formed in the outer side wall (46) of the tubes (42), extend through one of a series apertures (40) formed in the C-shaped posts (38), and are threaded into sleeves (48) secured to the inner side walls (44) of the tubes (42) by bolts (50).

Abstract: Apparatus (200) for opening the closure flaps (22-25) of a carton (12), for presenting the carton (12) for loading, and for closing the closure flaps (22-25) is disclosed including a carrier (202) which initially receives the carton (12). The carrier (202) carries the carton (12) into a carriage (226), with the carton (12) sandwiched therebetween. The closure flaps (22-25) are opened by a device (242) including fingers (254-257) which are pivoted to an expanded position after their insertion through an opening (27) in the closure flaps (22-25). An elevator (212) raises the carton (12) in the carriage (226) while the carton (12) is still under compression, with suction cups (56,171-173) then being attached to the closure flaps (22-25). The carriage (226) can then be moved to a loading position and back where the closure flaps (22-25) of the loaded carton (12) are fan folded by a device (120). The elevator (212) can then be lowered where the closed carton (12) can be pushed therefrom.

Abstract: A device (10) is disclosed including a discharge unit (54) having a vertical conveyor (56) formed by a pair of vertically arranged belts (58) each including circumferentially spaced shelves (60) defining a plurality of evenly spaced flights. A diverting conveyor (16) is pivotally mounted about its infeed end so that its outfeed end can be moved to be synchronous with one of the flights of the discharge unit (54) or to an overflow position. In particular, a servo motor (50) pivots the diverting conveyor (16) under the control of a controller (74) depending upon whether product is detected by a sensor (52) in the diverting conveyor (16), upon the rate that the flights of the discharge unit (54) are moving, and upon the pivotal position of the diverting conveyor (16). The device (10) is then able to place products which are fed to the diverting conveyor (16) with random spacing into the flights without bumping or bunching the products together.
