Title: Apparatus for producing filter tip cigarettes
IPC: A24D3/02
Filed: 1969-02-10
Abstract: 1,219,744. Cigarette making machines. R. J. REYNOLDS TOBACCO CO. 10 Feb., 1969 [14 Feb., 1968], No. 7178/69. Heading A2C. Apparatus for producing cigarettes with filter tips of the kind having a chamber containing granular material, e.g. charcoal, comprises means for feeding discrete tubular elements to a filling station, each tubular element consisting of a tobacco section and a hollow tube section of tipping material, e.g. cork paper, defining the chamber, and means for filling the hollow tube sections with the granular material. The discrete tubular elements 28 are produced by apparatus (not shown) that feeds tobacco on to a paper web to make a continuous rod which is cut into lengths each of which corresponds to two cigarettes. These lengths are then spaced apart endwise a predetermined amount and cut lengths of tipping material introduced to span the spaces, being secured by adhesive and rolled over to form the hollow tube sections. The continuous rod so formed is then severed at the middle of each hollow tube section and the middle of each tobacco section whereby successive elements 28 are delivered oppositely oriented. A kicker cam 82 projects the elements on to a grooved, rotating drum 80 and a "turn-around" device 84 ensures that all of the elements are similarly oriented on the drum 80, on which they are held by vacuum, before they are transferred by a grooved wheel 86 to a grooved drum 110. Associated with each groove on the drum 110, in which a cigarette is held by vacuum, is an apertured granule-metering slide 116 movable radially on the upper surface of the drum under the control of a fixed eccentric 117. As the drum rotates, each slide receives a granule charge from a hopper 114 and drops it into the hollow tube section of a cigarette, whereafter the cigarette is transferred to a drum 120 having plungers reciprocable by a stationary face cam 140 to press sealing plugs cut from a rod of cellulose acetate material into the ends of the hollow tube sections. Heat may then be applied to bond the plugs in position, and the finished cigarettes are delivered by a wheel 150 to a belt 152.

Title: Improvements in weighing scales
IPC: G01G13/32
Filed: 1933-03-10
Abstract: 403,839. Automatic-feed weighers. TOLEDO SCALE MANUFACTURING CO., Monroe Street, Toledo, Ohio, U.S.A. March 10, 1933, No. 7302. Convention date, Nov. 4, 1932. [Class 143.] In a weighing-scale photo-electric means controlled by the movements of the mechanism are arranged to control vibrating means for feeding material to the scale. As shown, a weighing scale of known type employing an indicating pointer 28 moving over a chart 32, is fitted with a photo-electric element 34 enclosed in a light-proof casing 35 having a narrow aperture 36 stationed directly beneath the zero indicium 33 of the chart. The indicating pointer carries a flag-like projection 41 arranged to pass between the aperture 36 and an electric lamp 37, Fig. 5, supported by a bent rod 40. A vibratory feeding device comprising a trough 43 agitated by an electric reciprocating motor 52, is supplied from a hopper 44. The trough is mounted on a tapered frame 47 supported by two flexible ribbons. The vibrations imparted by the motor give the trough a vertical and longitudinal movement. The control circuits are shown in Fig. 5, and are supplied from lines 59 fed by a source 60. Leads tapped from a transformer 61 supply current to the lamp 37, thermionic tube 64 and to one side of the photoelectric element 34 the other side being connected to the grid of the thermionic tube. The plate circuit of the thermionic tube includes a relay coil 68. A potentiometer 71 is provided for adjusting the grid potential so that the current passing through the relay coil 68 is sufficient to actuate the relay only when the photo-electric element is illuminated. Rheostats 79, 102 permit the amplitudes of the vibrations for the main and dribble feeds to be adjusted. In operation, a starter switch 73 is pressed thereby actuating a mechanically-latched three-pole relay 76 to energize a relay 81 which closes the circuit of the reciprocating motor 52 to feed the material to the package on the scale pan. As the weight increases, the flag-like projection on the scale pointer intercepts the light passing from the lamp 37 to the photo-electric element and diminishes the current through the relay 68 allowing a switch blade 91 to engage a contact 92 and de-energize a relay 94. The relay 94 energizes a release coil 100 to unlatch the relay 76 and throw the resistance 79 into the motor circuit to reduce the vibratory feed to a dribble. The flag-like projection on the pointer slowly crosses the light beam to admit the light again to the photo-electric element. The resulting increase of current, amplified by the thermionic tube, again energizes the relay 68, opens the contact 91, 92, de-energizes the relays 94, 81 and stops the feed motor. On removal of the filled package the indicator and circuits revert to the starting position.

Title: Road vehicle internal combustion engine starting systems
IPC: F02N11/08
Filed: 1974-02-19
Abstract: 1499322 Starting internal combustion engiries LUCAS ELECTRICAL Ltd 17 Feb 1975 [19 Feb 1974] 7476/74 Heading H2H A vehicle starting system comprises a solenoid 21 for moving a starter pinion into engagement with a toothed wheel on the vehicle engine, a starter motor 51 for driving the pinion, an ignition and starter switch 13, means operable when a starter contact 15 of the switch is energized for energizing the solenoid and subsequently energizing the starter motor after a delay, and an inhibiting network operable when the starter motor is energized to prevent reenergization of both the starter motor and the solenoid until an ignition contact 14 of the switch has been deenergized. When the switch 13 is moved to energize both the contacts 14, 15, a transistor 17 is switched on to energize a relay 18 and close a contact 19 which enables the energization of the solenoid 21 for moving the starter pinion. A capacitor 24 is charged via a diode 16 and a resistor 23 and after a delay switches on a transistor 28 to energize a relay 31 which closes its contact 32. A relay 33 is therefore energized and closes its contacts 33a to drive the starter motor 51. The closure of the contact 32 also switches on transistors 36, 37, 44 of the inhibiting network thereby discharging the capacitor 24 through the transistor 44. If the switch 13 is returned to the ignition position, the relays 18, 31 are de-energized but the transistor 44 remains conductive so that movement of the switch to the start position does not enable the charging of the capacitor 24 or the conduction of the transistor 17. Neither the starter motor 51 nor the solenoid 21 can be energized until the switch 13 has been moved to its off position.

Title: Radiant energy pyrometers
IPC: G01J5/52
Filed: 1963-02-26
Abstract: 974,194. Radiant-energy pyrometers. LEEDS & NORTHRUP CO. Feb. 26, 1963 [March 5, 1962], No. 7713/63. Headings G1A and G1D. A radiant energy pyrometer comprises a variable brightness lamp 11, whose brightness depends on the electrical current flowing therethrough, and which may be matched against the brightness of the object whose temperature is to be measured, and an adjustable potentiometric arrangement 15, 16 in circuit with the lamp and adapted to produce an output signal dependent on the current and the setting of a contact 17, i.e. the voltage across the resistor 16 and that part of the resistor 15 below the contact 17 in Fig. 1, the setting being adjustable until the signal equals a reference signal, i.e. the voltage across a standard cell 19, so that it then indicates the temperature of the object, and a circuit 20 responsive to any difference between the output and reference signals to automatically vary the current to maintain the difference substantially at zero. In use the operator lights the lamp filament 12 against the object whose temperature is to be measured and the contact 17 is moved by hand until the filament disappears against the background. Since the circuit 20 adjusts the current through the lamp and potentiometer arrangement so that the output signal voltage of the arrangement is always equal to the voltage of the standard cell the temperature of the object may be read off directly on a calibrated scale 18. The circuit 20 which is described in the Specification incorporates a chopper-type amplifier and gives a square wave output which is converted, amplified and fed to the lamp 11. In an alternative arrangement in which the scale 18 is linear, the resistance 15 is replaced by a network including two variable resistances ganged for simultaneous movement, the relationship between filament current and resistance contact movement being non-linear. A suitable circuit incorporating transistor amplifiers is described in the Specification. The invention may also be applied to pyrometers in which the object and filament are viewed alternately by a photo-cell controlling an electric motor drive for the potentiometer adjustment to maintain a brightness match. U.S.A. Specifications 2,176,087, 2,252,015 and 2,459,730 are referred to.

In a lamp sealing machine of the type described in Specification 196,591, [Class 39(iii)], comprising a rotatable turret provided with work-holding heads around its periphery and heating means at work stations adjacent to the path of the heads, each head having a vertical spindle which rides upon a fixed cam track at its lower end, and at its upper end supports a lamp mount within the neck of a bulb held in axial alignment with the mount, the vertical spindle 7 is formed by concentric inner and outer sleeves 11, 12 respectively, with a longitudinal passage through the inner sleeve 11 and one between the sleeves, and a shoe member 21 which rides upon a fixed cam track 22 is adjustably mounted upon the bottom end of one of the sleeves 11, 12 and is formed by integrally connected concentric tubular portions which constitute telescoping extensions of each of the sleeves and are adjustable therealong. In the example the shoe 21 is screwed upon the lower end of the outer sleeve 12 and retained in position by a lock nut 31, this adjustment permitting accurate positioning of the mounts relative to the necks of the bulbs to which they are to be sealed. A web 26<SP>1</SP> which is integral with the shoe 21 carries an inner tubular sleeve or hub portion 25 which fits snugly on, and is slidable upon, the lower end of the inner sleeve 11. During the heating of the neck 5 of the bulb while at certain work stations the lower end of the inner sleeve 11 is aligned with a passage 23 in the cam track 22, which provides an exit for air vented from the bulb, and at a subsequent station or stations, after the neck has sealed to the flare 3, a part of the annular space between the wall of the shoe 21 and the inner sleeve or hub 25 is aligned with an air-inlet passage 28 adjacent to one of the passages 23 in the cam track. Compressed air from a pipe 29 is thus introduced and passes upward between the two sleeves 11, 12, to an outlet slot 26 in a flange 27 in the mount support, being thereby directed against the inside surface of the bulb neck 5 to cut off the excess neck portion or cullet below the flare 3.
