Title: Control for cigarette making machine
IPC: A24C5/34
Filed: 1951-08-28
Abstract: 718,904. Automatic weight control. AMERICAN MACHINE & FOUNDRY CO. Aug. 28, 1951 [Oct. 2, 1950], No. 20298/51. Class 38(4) When a dielectric detector is used to control e.g. the feed to an automatic cigarette-making machine, the output of the detector is subject to error due to variation in the moisture content. To enable representative groups of cigarettes to be removed for check weighing, a timing circuit is used to indicate when the output-of the detector is steady (to avoid selecting cigarettes which have been subject to tobacco feed alterations). The timing circuit may ring a bell or initiate automatic removal of selected cigarettes for test and the test results may automatically correct the detector output. Timing circuit, Fig. 2. A direct current output signal from the detector is applied through an integrating circuit (potentiometer 54, capacitor 56) to the parallel connected grids of a cathode follower 64 and phase inverter valve 66, (to invert the negative signal produced e.g. by heavy cigarettes) supplying the grid of a thyratron 98, to cause the thyratron to fire when the signal is outside predetermined limits (diodes 88, 90 prevent interaction between the valves 64, 66). Firing of the thyratron operates relay 102 to interrupt the timing circuit 104 comprising a conventional R.C. network in the grid circuit of a valve controlling a relay in an indicator or control circuit. Automatic check weighing, Fig. 3. The control relay energizes solenoid 150 to actuate a one-revolution clutch 154 to drive a number of sequentially operating cams on a shaft 156. Cam 170 closes a circuit to a suction valve connected to a suction transfer head 186 which lifts cigarettes from the conveyer 220. Cam 216 lifts a rack 210 to swing the suction head over the scale pan to discharge into a scale pan 222. Cam 233 (driven by sprockets and chain from shaft 156) tilts the scale pan to discharge cigarettes into a hopper 242. The scale pan operates a potentiometer 231 applying a signal to an electronic convertor 244 controlling a servomotor 246 which adjusts the setting of a dielectric detector 248.

Filed: 1926-08-18
Abstract: 280,641. Drury, C. A., and Drury, J. E. Aug. 18, 1926. Machines supported by rotary propellers; planes, construction of; propelling; steering and balancing. - Blades of the form shown in Figs. 5 and 2, tapered in thickness from the fuselage to the tips and either parallel edged or tapered in width towards the tips are freely mounted on transverse axes d. Fig. 12, so as to rotate automatically in the airstream. The curvature of both concave and convex parts increases towards the edges of the blades. The blades are of high aspect ratio which is at least 7 : 1. The bearings of the blades are constructed to allow a certain amount of oscillation subject to the control of the pilot and the fore and aft position and inclination of the blades axes relative to the centre line of the machine may be adjusted or the rotation of the blades may be retarded or accelerated for steering and balancing purposes. Instead of adjusting the fore and aft position of the blades, a tractor propeller V may be so moved. A tail plane W<1> with elevators W is provided. Blades of this form may be placed in superposed staggered relationship or arranged in tandem the diameters of successive blades being graded, the larger towards the rear. Where the blades are separated by the machine body, a blade preferably of the form shown in Fig. 2 may be placed above the gap in the draught from the tractor propeller. Two tractor propellers abreast or on concentric shafts may be used. Each blade may be built up on a tube or box girder and covered with plywood or sheet metal and may be slotted as shown in Fig. 5 to oscillate across a shaft K passing through it. The extent of the oscillation may be controlled by a flat sided cone L, Fig. 6, adapted to be moved along the shaft to penetrate to a varying extent into the slot end. Alternatively an enlarged circular hole in the blade end may bear loosely on an axially movable cone. For adjusting the inclination and position of the blade and for controlling the direction of the oscillatory movement, each end of a shaft N, Fig. 10, fixed to the blade has a bush O sliding in a slot t in a plate T which has a ring T<1> on its surface sliding in guides u on the frame. Two control cords R, R<1> opposed to a spring S enable the plate T and slots t to ba tilted or the plate moved backwards and forwards in the guide u. A modified bearing is described in which a bush on the shaft N bears within an enlarged ring subject to the constraint of a sickle-shaped plate hinged to the ring and movable by the pilot.

Sponge iron is produced by directly reducing materials containing iron oxide with carbonaceous reducing agents, e.g. coal or lignite, without melting, e.g. at 1000-1250C., in a rotary kiln provided with shell pipes or burners, the reducing agent being continuously fed into each section of the reducing zone of the rotary kiln, in the same direction as the gas flow, so as to be distributed on to the charge bed surface, the feedrate being sufficient to replace the reducing agent consumed in that section and maintain in each section the amount of reducing agent present in the material discharged from the kiln, preferably 2-15% of the iron oxide, sufficient to prevent reoxidation of the iron produced. This amount is preferably separated from the sponge iron discharged and returned into the kiln. A sulphur-binding material, e. g. limestone or dolomite, may be added to the charge which is preferably preheated to the reduction temperature before charging.

Title: Improvement in devices for registering call charges in communication transmission systems
IPC: H04M15/38
Filed: 1938-07-12
Abstract: 516,892. Automatic exchange systems. TENNANT, W. J. (Mathias, M.). July 12, 1938, No. 20671. [Class 40 (iv)] A charge-printing device responsive to impulses for registering charges for calls is provided with automatic means to prevent the printing of charges below a predetermined amount. The relay I is energized by each charge impulse and through magnet G steps the type wheel T and the associated cam C by means of a ratchet Z and a pawl b. The relay H, and in consequence the printing magnet D, cannot be operated until the contacts m are closed by the cam C and this requires a predetermined number of impulses. Relay V is slow to release and keeps the circuit open at v during a train of impulses. At the end of a train, the circuit is closed at v and the magnet D is energized to print the charge. The crank L momentarily opens the contacts d, and H releases. Without further impulses, the magnet G and the relay V then interact through the circuit k, v, h2, G, 'd, to return the type wheel to the zero position. The means for preventing printing of charges can be made inoperative by means of a switch US which short-circuits the contacts m. Other type wheels may be mounted on the shaft A for recording the time and the date of the call.
