Abstract: 897,234. Zoom lenses; view-finders. REVERE CAMERA CO. Dec. 16, 1959 [May 29, 1959], No. 42752/59. Class 97(1). A cinematographic camera includes a zoom lens assembly having at least one fixed element and at least one movable element which is connected to a motor by transmission means which is manually controllable so that the motor can move the lens either towards or away from the fixed lens, the movable element being connected with the movable lens of a view-finder so that the zoom lens and view-finder can be simultaneously adjusted. As shown in Fig. 1 the zoom lens includes a movable lens-carrying part 12 connected at 24 to frame 19 which supports the movable lens-carrying part 16 of a view-finder. The frame 19 has a rack 36 engaged by pinions 34, 35 which are normally spring loaded at 37, 38 out of engagement with clutch gears 32, 33 which are continuously rotated by a pinion 27 connected to the shaft of a spring motor 26, which is connected to drive the film spools of the camera. By pressing a button 41, the pinion 35 is caused to engage the clutch gear 33 so that the rotation of the pinion 35 will via the rack 36, move the lenses 12 and 16 in one direction. Movement of these lenses in the opposite direction is effected by pressing a button 42 so as to engage the pinion 34 with the clutch gear 32. In a further form, Fig. 4, selection of the direction of movement is effected by movement of a lever 111 to pivot a plate 110 and thus bring either a pinion 108 or a pinion 109 into engagement with a rack 114 connected with the movable lenses of the zoom lens and view-finder, these pinions being driven via a train of gears from a motor which may be an electric or a spring motor and may be separate from the motor which drives the film spools. In a third embodiment the motor is connected by a belt drive 203 to a gear 205 meshing with a gear 206, the shafts of these gears having spring-mounted thereon, clutch gears 207 and 208 which engage a rack 213 connected to the movable lenses. Movement in the required direction is, in this case, effected by depressing the appropriate gear 207 or 208 against its spring so as to mesh with the pinion 205 or 206 (Figs. 6 and 7 not shown). Another form is described (Fig. 8 not shown) in which a pulley is belt driven from the motor and carries a gear which can be moved by a control lever into engagement with one or other of two racks. And in another form, Fig. 9, the motor drives a friction disc 401 adjacent to which is a friction roller 404 displaceable by a lever 408 on a shaft 405 carrying a screw and nut drive for the movable lenses. In this case the direction of movement is selected by operating the lever 408 so as to displace the friction roller 404 into engagement with the friction disc 401.

Abstract: 431,338. Ticket - issuing machines. BELL PUNCH CO., Ltd., 39, St. James's Street, London. Jan. 3, 1934, No. 251. Addition to 426,326. [Class 106 (iii)] In ticket-issuing machines as described in the parent Specification wherein means are provided for feeding and simultaneously printing, during each ticket-issuing cycle, a predetermined length of ticket strip, the severing mechanism, which cuts-off the strip at the point of tangency of the feeding and printing rollers, is formed as a separate entity, and means are provided for automatically reciprocating the severing mechanism relatively to the fed strip in order correctly to position the strip for the operations. The feed surfaces of a combined printing and feed roller 2 comprise an arc of printing type 8 and a pair of type rollers 9, 10. On depressing a key 18, a motor-driven shaft 24 drives through gearing 23, 25, 27, 29 the roller 2 one complete revolution. At the same time a cam 30 swings about a pivot 16 a bracket 15 carrying a pressure-roller 3 constituting the other feed roller, which is thus moved to the chain-line position, bending the leading end of the ticket strip 1 as shown. Continued rotation of the roller 2 feeds and prints the strip which is passed through the open gate of the severing mechanism 13, 14 on the movable bracket 15, and is delivered by ejector rollers 6, 7 through a gate 4. The return movement of the bracket 15 displaces the roller 3 and the severing mechanism along the now stationary length of the fed strip, and a pin 33 on the cam 30 thereupon operates a cam 34 fast with the guillotine blade 13, which cuts-off the fed length of the strip. If the ticket-forming strip is partially preprinted, the feed roller 2 may be formed with peripheral feeding surfaces in addition to those constituted by the surface of the printing type.

Abstract: 1394428 Wired glass PILKINGTON BROS Ltd A S ROBINSON D G LOUKES and J LAWRENSON 23 Aug 1972 [16 Sept 1971] 43268/71 Heading C1M A method of manufacturing wired glass by the float glass process, in which a flow regulating member is disposed across the molten metal bath which member is wetted by the molten glass, locally heating the glass in the region of the member reinforcing wire is fed continuously into the glass upstream of the member and guided beneath the member and the glass is rapidly cooled downstream of the member. The flow regulating member preferably includes an electrode 18 so that the local heating can be achieved by passing electric current from the member into the glass and to a second electrode spaced from the regulating member. Alternatively a second electrode 50 is mounted on the regulating member spaced from the first electrode 49 by an insulating plate 51 (Fig. 7). The wire may be guided beneath the regulating member by a transverse plate 25 of refractory insulating material which is attached to the electrode 18 but dipping deeper into the molten glass. In another embodiment (Fig. 8) the flow regulating member is constituted by a circular cross-section bar 60 which is immersed in the molten glass. The wire 31 is fed into the tank containing the metal bath from an electrically insulated reel 32 through a slot 37. Escape of protective atmosphere from the tank is prevented by forming a gas curtain across the upper end of the slot. The rapid cooling of the glass ribbon is achieved using an overhead cooler 40 and U-shaped tubes at the sides of the tank which dip into the molten metal. The support plate 20 for the flow regulating member 17 is cooled by water cooled tubes 21. The electrodes are formed of stainless steel, molybdenum, carbon, tungsten, tantalum, niobium, iridium, ruthenium, palladium or platinum. The insulating plates may be sillimanite or a sintered fused silica. Specification 1,393,118 is referred to.

Abstract: 1363744 Electro-medical apparatus SIEMENS A G 17 Sept 1971 [19 Sept 1970 (2)] 43572/71 Heading G1N In an e.c.g. processing circuit, the train of signals constituting the e.c.g. is applied at 1, the signals being squared at 2 to make all signals positive, the squared signals being applied to a threshold detector which provides a first output signal whenever a squared e.c.g. signal exceeds a threshold and a second output signal when said squared signal falls below said threshold, the first output signal triggering a time dependent circuit 4, 5 which provides an enabling signal to an AND gate 8, which also receives the e. c. g. train or the output of detector 3, a predetermined time after the time dependent circuit is triggered, thereby eliminating at the output of AND gate 8 spurious signals in the e.c.g. whose square value does not exceed the threshold for the predetermined time. As shown, the threshold detector 3 includes a multi-vibrator and the time dependent circuit includes a pulse generator 4 and a counter 5, the counter 5 providing the enabling signal at I after the predetermined time. Alternatively, a sawtooth generator combined with a threshold detector may be utilized. To indicate any ventricular extrasystoles in the e.c.g. train, the e.c.g. signals at the output of AND gate 8 are applied to a unit 10 which detects the R waves and applies its output to a switching circuit 12 which provides a 100 m. sec. pulse in response to each detected R wave, this pulse being applied to an AND gate 13 which is enabled by a signal from the time dependent circuit when a squared signal exceeds the threshold for more than a predetermined interval e.g. 60 m. sec. The pulse generator and counter or the sawtooth generator may again be used for this purpose. The subject matter of this last paragraph forms a basis for the main claim of Specification 1363745.
