Abstract: 1,105,009. Delivering cigarettes &c. AMERICAN MACHINE & FOUNDRY CO 13 Dec., 1966 [20 Jan., 1966], No. 55807/66. Heading A2C. [Also in Division B8] In an apparatus for feeding cigarettes or filter rods, rods F fed from a rod-making machine are introduced one at a time from a shoot A, by an introduction means E comprising a roller 32 and two parallel belts 12 of a conveyer C, into a reservoir R from which they pass down an inclined chamber 34, having an adjustable agitator plate 36 and a spring mounted yieldable top plate 38, into a lower hopper L from which the rods F then pass between counter rotating toothed rollers 48 into a curved channel 56 and thence into grooves 58 of a feed drum 60. A plate 22, underlying the upper run of the conveyer C, may be adjusted by means of a screw 28 to vary the height of the entrance means E to accord with the diameter of the rods F to be fed. In use, stopping of the feed drum 60 results in the reservoir R being filled until it reaches a preset level detected by a photocell system 62-64 which system then stops the rod-making machine that supplies the shoot A. A time delay switch then stops the conveyer C and the feed roller 32. A second photocell system 66-68 is provided to stop the feed drum 60 should the reservoir R empty due to failure of the rod supply. In a modification, Fig. 3, where a high rod delivery rate is required, the rods F are fed from a plurality of sources directly on to the belts 12 towards the roller 32, refuser rolls 70 restricting the feed to the roller 32 to a single layer of rods F. The apparatus may be used for feeding cigarettes and/or filter rods to a filter tip-cigarette uniting device, or for feeding completed cigarettes to a packaging machine.

Title: Ignition advance device
IPC: F02P11/02
Filed: 1971-12-20
Abstract: 1371639 Automatic control for ignition advance mechanism OPTIMIZER CONTROL CORP 20 Dec 1971 [21 Dec 1970] 59036/71 Heading G1N The automatic ignition advance mechanism of an I.C. engine incorporates a solenoid controlled valve which cuts out the advancing mechanism when the engine speed, measured electrically, is below a predetermined value, or when the brake pedal is operated, except when the engine temperature, sensed by a bi-metallic strip, is above a predetermined value. Figs. 2 and 2A show an ignition transformer 37 energized by a car battery 42, the secondary winding 38 feeding spark plugs 28 via a distributor 25. The degree of vacuum in the inlet manifold 59 is fed to a diaphragm member 48 connected by rod 51 to the rotor plate 26, whereby ignition timing is automatically adjusted in accordance with the degree of vacuum in the inlet manifold. The engine speed is sensed by the pulse rate derived on line 71 from the ignition transformer 37, which controls the charge voltage on a capacitor 81. Normally transistor 80 is blocked and capacitor 81 is charged from positive line 66 via resistors 82, 83. When points 18 open to develop a high voltage pulse for spark plugs 28, a positive pulse is produced on line 71 which causes trainsistor 74 to conduct, followed by transistor 80 and capacitor 81 is discharged. Thus the peak voltage on capacitor 81 is determined by the time interval between pulses and is therefore inversely proportional to engine speed. This voltage is averaged by capacitor 86 and resistor 89, and compared by transistors 90, 91 with a voltage varying in an inverse manner derived from resistor 82 in the charging circuit to capacitor 81. At low speeds transistor 90 conducts and transistor 91 is blocked and vice versa. Thus the output voltage on line 101 changes from one level to another at a predetermined engine speed. At high speeds this voltage is amplified by transistors 103, 105 to energize solenoid 56 and open valve 55, allowing the automatic ignition advance member 48 to operate in accordance with the inlet manifold degree of vacuum. At low speeds this voltage is insufficient to unblock transistor 103, transistor 105 is also blocked, solenoid 56 is de-energized and valve 55 is closed, blocking the connection between the inlet manifold 59 and the diaphragm member 48, thus prohibiting automatic ignition adjustment. When the brake pedal 110 is operated, a switch 120 reduces the base potential of transistor 91 which is thereby blocked and automatic ignition control is inhibited irrespective of engine speed. When the engine temperature exceeds a preset value, a bi-metallic switch 128 is closed, allowing transistors 103, 105 to conduct and energize solenoid 56, whereby automatic ignition control is allowed irrespective of engine speed and position of brake pedal 110.

Abstract: 1,214,550. Dual ramp digital voltmeters. SOLARTRON ELECTRONIC GROUP Ltd. 14 July, 1969 [20 Dec., 1968], No. 60791/68. Heading G4H. In a dual ramp digital voltmeter after the integrator has been charged for a fixed time interval by the input signal the application of the reference signal to discharge the integrator is delayed to allow the integrator to settle. During this delay the potential of the input may be determined and the required reference signal polarity is selected. As described after a delay D1, D2, NAND gates 40, 41 (Fig. 1) enable either FET 42 or 43 in accordance with the polarity of the integrator output so that after a delay D1 + D3 a positive or negative reference is applied via FET 46 to the integrator to discharge it. The number of pulses accumulated in counter 32 whilst the indicator is discharging is displayed on Nixie tubes together with the polarity bit. The manner of count may be modified to allow for non- linearity in transducer outputs.
