On engagement of a clutch the respective shaft 90 or 110 can be rotated, to cause via gears 80 the rotation of arm 50 if possible, a ball 52 in a groove 111 of the shaft 10 preventing axial movement of the gear-box 40. On the limit of movement of arm 50 being reached (through a stop, not shown) the ball 52 is now aligned with an axial groove 111 of the shaft, and due to the clutched sprocket now being locked against movement, the gear-box 40 and the arm 50 are moved along the shaft 10 by the chain. The clutches shown are operated by a lever 140 one end of which runs in grooves in a programmer so that the lever can be moved to open one clutch 120, 130 and close the other at the opposite limit of movement and so the cycle of events is here repeated. The programmer (Figs. 3 and 4) may have means for disengagement of both clutches (as shown in Fig. 2) to stop the action, and the clutches may be electromagnetically operated instead of by the lever shown.

Title: Flying spot scanner
IPC: H04N1/04
Filed: 1975-12-11
Abstract: 1525028 Facsimile device RCA CORPORATION 11 Dec 1975 [23 Dec 1974] 50872/75 Heading H4F A flying spot scanner, free of ambient light interference, comprises means to deflect a light beam in a scanning mode across, for example, a document, means for modulating the intensity of the beam at frequency fc, a photodetector for receiving light, from said document, including the modulated beam further modulated by information on the document, a filter for receiving the output of the photodetector for passing the carrier fc and sidebands but for attenuating frequencies #fa, and means for receiving the output of the filter for demodulating the produced signal at frequency fc. As described, light from laser 10 modulated at 1À2 MHz is reduced to a circular beam and focused, by optics 14, onto document 12 via scanning mirrors 16, 18 driven by galvanometer motors. Photodetector 20 detects light from a (solid) angle represented by 26, and so will receive ambient light reflected from the document. The frequency fc is chosen so that the lower sideband frequency fc-fm due to a maximum modulating video frequency fm is above the maximum frequency fa of variation of the ambient light (Fig. 2, not shown). Typically fm is about 30 KHz and fa is a few hundred Hz. The output from the photodetector 20 is filtered to eliminate all but the carrier frequency and its sidebands, and is then demodulated at 52 to produce the modulating, video signal, which is then free of noise due to ambient light. The video signal may be applied to a threshold circuit to produce an "on/off" or two value signal in the case of printed documents. Either the two-level or continuous tone signal may then be transmitted to a facsimile printer which may be at a remote location.

Title: Improvements in or relating to apparatus for raising and lowering blinds
IPC: E06B9/80
Filed: 1965-12-09
Abstract: 1,077,705. Roller blinds. H. WIEGELMANN and H. GERMANN. Dec. 9, 1965 [Dec. 10, 1964; April 10, 1965], No. 52319/65. Heading A4B. Apparatus for raising and lowering a blind wound on a rotatable cylinder comprises a winding roller (7) selectively driven through reduction gearing (13-16) by a reversible electric motor (11), a strap (9) wound on the roller (7) and extending to the cylinder to cause rotation of the latter when the motor is operative, and an electrical control circuit including microswitches operatively associated with means for sensing the amount of the strap (9) wound on the roller (7) to stop the motor when the blind has reached a raised, lowered, or pre-selected intermediate position. In one embodiment (Fig. 2) a spring biassed lever (21) bears on the strap roll (33) to engage adjustably positioned microswitches (24, 25) at the desired limits of pivoting of the lever (21). In another embodiment (Fig. 3), the strap (9) carries spaced leather strips (133, 133<SP>1</SP>) which locally increase the effective thickness of the strap to operate microswitches (M I, M II) and stop the motor Alternatively, the microswitches could be actuated by magnets carried by the strap. In a further embodiment (Fig. 4), relaxing of tension in the strap (9) when the blind reaches an end position permits a lever (52) to pivot under the action of a spring (57) to press the strap (9) against an operating roller (55) for a microswitch (M II). The operating mechanism is detachably housed in a chest (2) embedded in the wall (1) at the bottom of a window. The transmission includes a gear box (13) in which the motor shaft carries a self-locking worm meshing with a worm wheel to automatically brake the roller (7) when the motor is switched off. The roller (7) is secured to its drive shaft by a pin (8) which is removable to permit manual rotation of the roller (7). The armature (41, Fig. 5) and field windings (42) of the motor are in series in two control circuits respectively including microswitches (M I and M II) and a manually operated, double-pole, rotary switch (26), reversal of which reverses the current through the armature windings and hence reverses the motor drive to the roller (7). In a mid-position (38, 38<SP>1</SP>) of the switch (26) the motor supply is cut off.
