Patent GB-1351620-A (GB)
Title: Telecine apparatus
IPC: H04N9/11
Filed: 1971-04-30
Abstract: 1351620 Telecine apparatus EASTMAN KODAK CO 30 April 1971 [30 April 1970] 12353/71 Heading H4F A motion picture film 11 is continuously moved by a sprocket 14 through a film gate 12 where it is scanned by a flying spot scanner 24. In the embodiments described each frame of the film is scanned three times by a raster which moves with the film across the aperture 13 of the film gate, the actual size of the raster being 2/3 that of the film frame so that when the film motion is taken into account the entire film frame is scanned by the reduced size raster. The vertical position of the raster scan is continuously controlled 52 in dependence upon the position of the picture frame being scanned, this continuous control in addition to effecting this vertical position control, also effects the above referred to size reduction. In Fig. 1 this is effected by a contact arm 51a of a potentiometer 51 which is driven by the sprocket 14 through gearing 43, the arm 51a making one complete revolution for every three scanning cycles (i.e. a complete scansion of each picture frame). If the film motion is stopped for projection i.e. scanning, of a single frame, the height of the raster scanned by tube 24 is restored to its full amplitude automatically since only a constant bias is added to the vertical sweep signal in unit 52, which constant bias positions the scanning raster in the correct position for scanning the film frame. The film motion may be started again with synchronization being effected correctly due to arm 51a supplying the correct bias. In further embodiments (Figs. 3 and 4, not shown) potentiometer 51 is replaced by a tachometer generator and ring counter combination, or by a disc having varying transmissivity which rotates between a light source and a photo-cell.

Title: Safety harness device
Inventor: WRIGHTON ROBERT JOHN
IPC: B60R22/41
Filed: 1969-03-10
Abstract: 1,219,226. Safety harness. PACIFIC SCIENTIFIC CO. 10 March, 1969 [9 April, 1968], No. 12517/69. Heading A3V. A vehicle safety harness comprises a frame 1 and a cover 52, a strap 8 wound on to a harness reel 5 rotatably carried by the frame, an inertia member 21 mounted on the reel for limited turning motion with respect thereto, locking mechanism 37 actuated by the inertia member on excessive acceleration of the strap from the reel, and safety means for preventing locking during initial manual pull-out of the strap comprising a slide 43 rotatable with the reel and having a projection 45 engaging a spiral groove 46 in the cover 52 thereby causing relative sliding motion between the inertia member and the slide during strap movement, the slide being positioned during initial pull out of the strap to engage the inertia member to prevent locking of the reel and being arranged to move out of engagement with the inertia member after the initial pull out to permit locking in the event of excessive strap acceleration. The invention is shown applied to a retractable safety harness reel of the kind disclosed in Specification 1,217,938; reel 5 is keyed to a shaft 4 by plate 15, and the shaft carries eccentric inertia member 21 at one end. On sudden strap acceleration, inertia member 21 which is pivoted at pin 20 to a flange 19 on shaft 4 pivots against the force of biasing spring 24 to engage teeth 29 within a cup member 27; the cup member is rotatably mounted on a shaft 4, and is thus driven by inertia member 21 and in turn drives a clutch spring 30; bifurcated lug 33 on the clutch 30 actuates locking bar 37 through spring lever 35, so that teeth 39, 39<SP>1</SP> on bar 37 engage teeth 40, 40<SP>1</SP> on plates 10 and 11, thus locking the reel 5. During initial manual pull out of the strap, a projection 49 on the slide 43 engages recess 47 in inertia member 21, and prevents it operating the locking mechanism; slide 43 is slidably mounted on shaft 4, so that as the shaft rotates a further projection 45 on the slide is acted on by the spiral groove 46 in the cover 52, and the slide moves transverse the shaft to place projection 49 in a further recess 48 in inertia member 21 whereon the inertia member is free to operate the locking mechanism on sudden strap acceleration. Arm 53 of the slide 43 may be resilient, giving a graduated control of the acceleration required to operate the locking mechanism. When the strap is nearly fully  paid out, a bevelled edge 50 of slide 43 abuts a pin 51 on the inertia member and pivots the member to operate the locking mechanism so that some strap always remains on the reel. The invention is also described for use with the flywheel type inertia reel mechanism of Specification 1,185,582.
