Title: Web supply assemblies
IPC: G03G21/00
Filed: 1974-05-14
Abstract: 1454604 Web tensioning RICOH KK 14 May 1974 [15 May 1973] 21202/74 Heading B8R A web tensioning device comprises a take-up reel 42, Fig. 1, on which the web 2 is wound, the reel 42 being prevented from rotation in a direction opposite to the direction of web winding by a set of gears of which gear 45 is provided with a uni-direction clutch 50, whereby the gears in conjunction with a pawl 58a and a ratchet wheel 57 cause the web to be wound on the reel 42 when a drum 1 is driven and the tension in the web overcomes the braking force applied by a uni-direction clutch 37 to a supply reel 23, Fig. 2. In operation, when a length of web is required to be fed from the supply reel 23 to the take-up reel so that a fresh portion of web 2 is displayed over the periphery of the drum 1, the pawl 58a is engaged with the ratchet wheel 57 and the gear 55, Fig. 2, is arrested, whereby rotation of the drum 1 causes a gear 51 which meshes with a sun gear 52 to rotate about the gear 52 and thereby impart rotation to the reel 42. The tensions induced in the web 2 by rotation of the reel 42 causes the spring clutch 37 to be released whereupon a length of the web 2 can be unwound from the reel 23. When rotation of the drum 1 is stopped and pawl 58a is released the clutch 50 prevents reel 42 from rotating in the opposite sense and the spring clutch 37 is restored to its reel braking position by a spring 32 which disengages a lug 35a from a stop 40, the co-operation of which corresponds to the disengaged state of the clutch 37.

Title: Alarm detectors
IPC: G08B13/187
Filed: 1972-05-06
Abstract: 1439325 Photo-electric surveillance unit KGM ELECTRONICS Ltd 6 Aug 1973 [6 May 1972] 21268/72 Heading G1A [Also in Division G4] A smoke, fire or intruder alarm system comprises a detector unit 1 including a light source 2 adjacent a lens 3 forming by way of mirror 4 an image of an area under surveillance and a set of photo-diode detectors 6 positioned in the image plane of the lens to form images of a plurality of retro-reflectors disposed in the area under surveillance. If one or more of the photo-diodes provides an output signal indicating a retroreflector is obscured a relay coil (RL2) Fig. 2 (not shown), is deactuated to give an alarm. A further photo-diode is connected in the opposite sense to the others and causes relay (RL2) to drop out if an obstruction in front of the detector unit reflects back to all the detectors. A yet further photo-diode detector monitors the output of the light source by way of optical fibre bundle 7 and controls the sensitivity of the other detectors accordingly, to compensate for the lamp ageing for example, whilst failure of the light source is indicated by operation of relay (RL1). The sensitivities of the integrated circuits forming, with the photo-diodes, the detectors, are individually adjustable by means of variable resistors. It is stated that the detectors may be used with a C.C.T.V. system and that when so used the detector output may be used to select and or energise T.V. cameras and or lighting equipment to conserve the life thereof and direct attention to the area concerned.
