Patent GB-2160431-A (GB)
Title: Exercise machine
Inventor: RUSE EDWARD THIPTHORPE
IPC: A63B21/22
Filed: 1984-06-20
Abstract: The machine has a flywheel 23 which is arranged to be driven through a dog clutch by manually pulling on a cord 39 which thereby moves a friction plate 24 of the dog clutch out of contact from the flywheel 23. Such action disengages the drive from a sprocket 21 driven by a crank wheel attached to a pair of pedals, and upon releasing the cord a pawl rides over a ratchet and a striker member on the cord actuates the dog clutch to move the friction plate into contact with the flywheel so that drive between the flywheel and the crank wheel is then engaged. Thus a user is able to initiate rotation of the flywheel by pulling on the cord and thereafter to maintain rotation of the flywheel by a pedalling action. The leverages of the foot pedals about the axis of the crank wheel (6) is variable (Fig. 1). <IMAGE>

Patent GB-2157235-A (GB)
Title: Color printer
Inventor: BARRUS GORDON BRENT
IPC: B41J15/16
Filed: 1985-04-11
Abstract: In an ink ribbon (120) for a color printer, the difference color zone (124, to 154) of the ribbon are arranged in a repeating pattern along the length thereof enabling the lightest color to be printed first followed by successively darker colors as the ribbon is advanced bidirectionally between the opposite ends thereof. A pair of barrier zones (156, 158, see Figure 5) having a blank ribbon zone (164) therebetween are disposed between each adjacent pair of color zones (160, 162) on the ribbon to prevent ribbon contamination due to bleeding of ink between adjacent color zones when the ribbon is wound on a reel. Ribbon contamination is further prevented by the blank ribbon zones (164) which absorb ink that rubs off onto the ribbon guides. The various different color zones are identified by one or more strips (166, 168) which extend across the width of the ribbon adjacent each color zone and which identify the color therein in bar code fashion. The color printer may be operated in a manner which provides multiple passes of each color zone through the print station between the shuttle assembly and the platen to prolong the life of the ribbon and to enable the printer to quickly advance to the next color zone with a minimum amount of search time. The print paper which is driven bidirectionally by tractor drives (30, 32, see Figure 1) above the print station is held in tension by an arrangement below the print station which employs a torque motor (202, see Figures 10-12 not shown) having an elastomeric of non-ink absorbing rollers (210). The ribbon path may include one or more roller guides (see Figures 13-17 not shown) consisting of a pivotable spool (224, 240) having opposite outwardly extending flanges (228, 230; 256, 266) and an outer surface of non-ink-absorbing material. <IMAGE>
