Filed: 1929-03-01
Abstract: 330,239. Film Ozaphane. Jan. 19, 1929, [Convention date]. Kinematograph apparatus. - In order to vary slightly the feeding speed of films they are led between a cylinder 1, Fig. 1, covered with rubber or other resilient material and a second freely mounted roller 2 adapted to bear with a variable amount on the resilient cylinder. The device may be used either in conjunction with an intermittent feed or as shown in Fig. 3 with a continuous feed through the gate in conjunction with an optical compensator which is varied simultaneously with the feed. This device comprises a lens 11 oscillated in a direction parallel to the film by a cam 15 bearing on the free end of a lever 13 pivoted at 12, and pivotally attached at 13 to the vertically moving spindle carrying the lens the motion of which is cushioned by an air chamber 29. The effective length of the lever 13 may be varied by altering the position of the pivot 12 mounted on the free end of a lever 26, angular movement of which is controlled by a rod 19 operated by a hand lever 27 eccentrically mounted on the shaft of the feed roller 2 so that simultaneous adjustment of the pressure between the rollers is effected. Fig. 4 shows an apparatus for maintaining a loop of film without tension before its introduction into the track 16. The film is fed between the smooth roller 22 and a roller 17 the spindle of which is eccentrically fixed on a spindle 19 carrying a roller 21 counterpoised by a weight 23. The smooth roller 22 tends to feed the film faster than necessary so that the loop is lengthened thus reducing the. pressure between the rollers so that the. feed momentarily ceases. The loop now shortens and the roller 21 under the action of the shortened loop re-establishes the, pressure and the film is again fed forward.

Title: Apparatus for controlling the rate of combustion in a solid fuel furnace
IPC: F23N1/02
Filed: 1952-03-18
Abstract: 737,383. Controlling fuel supply to solid-fuel furnaces. CROOK, C. June 18, 1953 [March 18, 1952], No. 6942/52. Class 51 (1). [Also in Group XXXVII] The fuel supply to a solid-fuel furnace is controlled, through electric circuits by a device responsive to variations in the flow of combustion. air or combustion products, in such a manner that the ratios of fuel to combustion air and fuel to combustion products are maintained at preselected values. As shown in the Figure, a furnace 1 has an exhaust flue 4 in which is a restriction 6; a conduit 10 leads from one side of the restriction to the interior of an airtight casing 9 and a conduit 16 leads from the other side of the restriction to the interior of a float 13 suspended from a pivoted arm 12 so as to be partially immersed in a liquid in a container 15 disposed within the casing 9. The arm 12 has secured thereto a contact arm 17 which co-operates with a cam 20 carried on a constantly-rotating shaft 21: the shaft 21 also carries a cam 23 which periodically opens the circuit of a relay 25 having contacts 26, 27, in the circuit of a motor 3 driving the fuel feeding mechanism. ' In operation, rotation of the shaft 21 causes the arm 17 to contact the cam 20 and closes the circuit of relay 25 which locks through contacts 20 and operates the fuel feeding motor 3 through contacts 26 and 27. The relay releases, at a fixed point in each revolution of shaft 21, when contacts 24 are opened by cam 23 and the cycle of operations is repeated. The pressure-responsive elements 13, 17 are so arranged that a decrease in the flow of combustion gases through flue 4 causes the arm 17 to contact the cam 20 at an earlier point in each cycle and so increase the average rate of fuel feed, whilst an increase in the flow of gases causes the arm 17 to contact the cam at a later point in each cycle and so decrease the average rate of fuel feed. In modifications the conduits 10 and 16 may be connected to another part of the furnace, e.g. on the outlet side of an induced draught fan or on the inlet side of a forced draught fan, where a flow of air or gases allows of a pressure difference being measured. The float 13 and container 15 may be replaced by a diaphragm element.

Abstract: 1383031 Road rollers B KALTENEGGER 15 Feb 1972 [26 Feb 1971] 7032/72 Heading B7H A road roller 1 having four rolls 2, 3, 4, 5 is provided with a motor 12 and a transmission unit 13 which drives the rolls at one side independently of the rolls at the other side, either forwardly, in reverse or idling, to provide a selective drive arrangement for steering. As described the input shaft 18 for the transmission unit 13 drives two separate gear trains (Fig. 3). The train at the left of Fig. 3, drives output shaft 44 (Fig. 5) and the train at the right of Fig. 3, drives output shaft 44<SP>1</SP>. Output shaft 44 drives the rolls 4, 5 via gears 58 to 62 and output shaft 44<SP>1</SP> drives the rolls 2, 3 via gears 58<SP>1</SP> to 62<SP>1</SP>. The two gear trains in the unit 13 are identical so that only one need be described. The input shaft 18 (Fig. 5) is provided with two gearwheels 22, 23 which are in constant mesh with gear-wheels 24, 25 (Fig. 6) which can be coupled to shaft 28 by clutches 31 and 32. Thus by engaging either clutch 31 or 32 a first-gear or second-gear ratio can be selected. The shaft 28 carries gear-wheel 34 which meshes with gearwheel 35 on shaft 36. The shaft 36 drives shaft 39 either directly through gears 30 and 38 and clutch 41 or indirectly through a reverse gear shaft 45 (Fig. 3), gear 48 and clutch 42. Thus by engaging either clutch 41 or 42 a forward or reverse drive can be selected. The shaft 39 drives output shaft 44 via gears 50, 43. All the clutches are hydraulically operated and are supplied with pressure fluid from a pump 63 (Fig. 5) on the input shaft 18. In operation the roller can be driven in a straight line, either forwardly or in reverse, at first-gear or second gear speeds, or can be driven along a curve by driving the rolls at one side in first gear and the rolls at the other side in second gear. Alternatively the roller can be turned by driving the rolls at one side forwardly and the rolls at the other side in reverse. The rolls may be provided with a vibration drive 73 (Fig. 1) taken from the motor 12.
