Filed: 1972-11-15
Abstract: 1395968 Television RANK ORGANISATIONLtd 27 Sept 1973 [15 Nov 1972] 52673/72 Heading H4F In a television camera-particularly a colour television camera-using a zoom lens 1, the degree of focus of the image produced by the zoom lens 1 and an optical assembly 5, on the target of camera tube 6 may vary with the setting, i.e. magnification of the zoom lens. This change of focus will be particularly harmful where three colour component images-red, green and blue are simultaneously produced by the zoom lens since simultaneous correction of the zoom lens for all three colours is very difficult. To overcome this focus variation, the distance between the camera tube target and the optical assembly 5 is varied in dependence on the setting of the zoom lens according to the known characteristic of the lens (e.g. Fig. 4b, not shown). In the embodiment of Fig. 1, compensation unit 8, coupled to the lens setting, produces a signal according to said characteristic for control of the position of the camera tube (e.g. red tube), and/or the optical assembly. The output of the compensation unit may be alternatively compared (Fig. 2, not shown), with a signal representing the distance between the camera tube and optical assembly, and any difference used to correct said distance. In the embodiment of Fig. 3, the compensation unit 30 produces a signal, for comparison at 20 with a setting indication signal from the zoom lens, derived according to said characteristic from the measured distance between camera tube and optical assembly, the comparison again giving a correcting signal. The compensation unit has a non-linear transfer charateristic and may comprise a differential amplifier having a parallel circuit of a fixed resistor and a voltage dependent resistor in both its input and a negative feedback path (Fig. 4a, not shown).

Title: Improvements in or relating to apparatus for testing cigarettes and other rod-like articles
IPC: A24C5/34
Filed: 1965-12-14
Abstract: 1,114,290. Testing cigarettes. HAUNIWERKE KÍRBER & CO. KOMM.-GES. 14 Dec., 1965 [23 Jan., 1965], No. 52986/65. Heading A2C. Apparatus of the kind in which cigarettes or the like are deposited in grooves of a conveyer and tested by introducing an air current into the ends of the cigarettes which are sealed on the outer surface by sealing means disposed at the ends of the grooves, is characterized in that a resilient annular sealing member is provided and is arranged to be engaged by pressure exerting means capable of changing the internal diameter of the sealing member. As shown in Fig. 2 the sealing means are mounted on a drum 600 and consist of valve sleeves 636 and slide valves 684 located therein. The slides are operated by a cam and follower 638 arrangement against the action of springs 642. Each slide includes a ring 628 which, when the slide is moved to the right as viewed in Fig. 2, passes over the end of a cigarette group G to be tested. Within a chamber 604 in the slide an annular sleeve 606 is located around which is disposed a resilient tube 602. In the testing position compressed air passes through a hole 622 in the valve sleeve 638, hole 620 in the slide, and opening 616 in the annular sleeve 606 so that the resilient tube 602 is forced radially inwardly to grip the end of the cigarette group. Alternatively the internal dia'meter of the resilient tube may be made smaller than that of the cigarette group in which case suction is applied instead of compressed air to increase its diameter during entry and exit of the cigarette group, Fig. 5 (not shown). The testing air current is applied through holes 638 and 634 to the chamber 604 and hence to the end of the cigarette group being tested. In a modification, Fig. 8 (not shown), the resilient sealing member consists of a ring of deformable material, the internal diameter of which may be varied by axially applied pressure. 1,114,309.
