Title: Improvements relating to remote indicating devices
Inventor: COLLINS HAROLD LANCASTER
IPC: G01F23/292
Filed: 1954-07-13
Abstract: 780,585. Photo-electric indicating systems. HOPKINSONS, Ltd. June 29, 1955 [July 13, 1954; May 5, 1955], Nos. 20489/54 and 13036/55. Class 40 (3). [Also in Groups XVIII and XXXVIII] A device for remotely indicating the water level in a boiler gauge, the height of a flame in a furnace, or the position of a pointer on a scale is described for its boiler gauge application, and comprises a gauge 1 illuminated by a lamp 3, a lens 4 receiving light from the gauge, a plate 6 having a vertical slot 10, Fig. 2, a photo-electric multiplier 13, a scanning disc 7 rotated by a motor 12, an electromagnet 14 and an amplifier and power unit 15 which supplies current to the motor 12 and multiplier 13, and receives the outputs from the electromagnetic pulse generator 14 and the multiplier 13 which it feeds to a C.R.T. 17. In operation the scanning disc 7 which has spiral slots 8 and magnetic material plates 11, rotates behind the slit 10 to scan the gauge twice per revolution. The light from the gauge undergoes a sudden change as a slot 8 passes the part of the slit 10 where the image of the water level is formed, as the result of which change the photo-electric multiplier 13 gives an electric signal the duration of which after the beginning of the scanning corresponds to the height of the water level. The electromagnet 14 has a synchronizing pulse generated in it as the plate 11 passes the slit 10 before the slit is scanned by the other slot 8. These pulses are applied to the C.R.T. 17 which causes the tube screen to be scanned by the cathode ray in synchronism with the scanning of the slot 10, and an amplifier 20 applies the output of the multiplier 13 to the modulating electrode 21 of the tube so that a vertical band is shown on its screen which is dark in one part and light in the other representing the appearance of the gauge.

Abstract: 665,714. Digital electric calculating-apparatus. FARRER, J. O (Remington Rand, Inc.). Aug. 9, 1949, No. 20750/49. Class 106 (i). Apparatus for generating electrical pulse trains, e.g. to be selectively used in electrical calculating apparatus, comprises a multivibrator 14, started by an electronic switching stage 13 under control of a switch 10, frequency divider stages coupled to the multivibrator for producing some of the pulse trains one of which consists of a single pulse, and coupling means between the frequency divider stages and the stage 13 for turning off the multivibrator when the single pulse ends. In the apparatus described, one or more of the pulse trains are selected by a keyboard 28, Fig. 1, to enter digits into an electronic accumulator including counter stages 35 as described in Specification 665,707. In operation, a digit key is depressed and then the start switch 10. A condenser 42, Fig. 2, is then discharged and a sharp positive pulse is applied to the grid of a pulse-generating triode 40, which sends a negative pulse 26, Fig. 5, a, over conductor 25 to change the condition of an unbalanced trigger stage 12 comprising a double triode 43. The output pulse 27, Fig. 5, b, is applied over conductor 39 to cathode follower stage 21 to supply a " 1 " pulse to the keyboard over line 63, and over conductor 45 to change the state of the trigger stage 13 and raise the potential on line 48 as shown at 30, Fig. 5, c, thus starting the multivibrator to produce pulses 31, Fig. 5, d. The multivibrator output is fed to cathode follower stage 20 to supply " 8 " pulses over line 94 to the keyboard (each pulse representing " 2 "), and also fed to frequency divider stages 15 and 16 to supply " 4 " and " 2 " pulses, Fig. 5, e and f, from cathode follower stages 22, 21, respectively. The output from stage 16 is also fed back over conductor 18 to stage 13 so that the trailing edge of pulse 33, Fig. 5, f, returns the stage to its normal condition (left-hand triode conducting), thus switching off the multivibrator. Pulses 32 and 33, Fig. 5, e and f, are sent also to a mixer stage 23 to produce output pulses, Fig. 5, g, which are fed to an inverter stage 24 which supplies " 6 " pulses, Fig. 5, h, to the keyboard.

Title: Improvements in cigarettes and in the manufacture of the same
IPC: A24C5/18
Filed: 1932-07-26
Abstract: 407,017. Cigarette-making machines; cigarettes. PODMORE, A., 58, Holborn Viaduct, London. July 26, 1932, No. 21121. [Class 130.] In a continuous-rod machine in which the rod is to be formed with alternate denser and less dense portions, corresponding to positions at which the rod will be cut, spaced increments of tobacco additional to the normal supply are delivered to a travelling web of cigarette paper or a conveyer band prior to the delivery of the normal supply thereto. The spaced increments may be separate from one another, or a continuous delivery may be such that it assumes a wave-like form on the paper web. The resulting cigarettes are more closely packed at the ends than in the middle. In one form, Figs. 1 and 2, an auxiliary feed chute 5 at the rear of the main chute 6 is supplied with tobacco by a pin wheel 9 and a picker roll 16, which may be extensions of the main pin wheel and picker roll. At the lower end of the chute 5, the tobacco is fed to the travelling web 7 by a rotary drum 10 having side flanges 10<a>, 10<b> and vanes 11 forming with the curved wall 12 of the chute a pair of measuring compartments. The drum is driven through chain gearing and may be driven intermittently through a Geneva stop drive. The vanes are provided with a cutting edge co-operating with a spring-pressed roll 18 for severing any strands of tobacco lying across the edge of the vane. The speed of the drum 10 may be such that the increment of tobacco as it is delivered to the web moves at substantially the same speed as the web. In a modification, the rear wall of the tobacco chute is pivotally mounted at its upper end and is oscillated by means of a link coupled to an eccentric, crank &c., the oscillating element being synchronized with the cut-off device so that the heaps or waves of tobacco produced will correspond to the position of the cut. The oscillating element may comprise a chute or a spring steel member, or may have an endless band travelling over its surface. In another modification, Fig. 5, the auxiliary supply of tobacco is delivered through a chute 5 upon an endless conveyer 25 travelling on drums 26, 27 and provided with spaced blocks 28. The conveyer is perforated between the blocks and is mounted between side walls to form a suction chamber. The portions of tobacco are thus held on the conveyer until they pass the edge of a baffle 32, then they are deposited upon the web 7. In a further form, a bucket wheel at the rear end of the chute rotates upon an axis transverse to the direction of movement of the paper web. The buckets are filled with tobacco from the shower or from a separate supply and deliver the tobacco at spaced points on the web.
