Title: Fluid pressure control system for the automatic regulation of variables
IPC: G05B6/05
Filed: 1952-02-14
Abstract: 777,240. Fluid-pressure servomotor control systems. BESTER, K. O. P. Feb. 14, 1952, No. 3989/52. Class 135. In a fluid-pressure apparatus for controlling a variable condition, such as pressure, temperature or fluid flow, the pointer 51 of an instrument measuring the variable actuates a baffle plate 53 to control the flow of a jet of air passing between discharge and receiving nozzles 27, 28 respectively, and the baffle plate is provided with down-turned control edges 53<SP>1</SP>. The output pressure from nozzle 28 controls a nozzlebaffle amplifier and the output of the latter is fed into pressure-responsive devices to restore the unit 27, 28, 53 to neutral position and also into a further amplifier, the effect of which on the final regulating unit is adjustable by means of a lever mechanism. The pressure air led to nozzle 27 consists of the discharge from a nozzle 22 of the first amplifier and its pressure is kept constant by means of a relief valve 24. The pressure of the air received by nozzle 28 is, of course, regulated in accordance with the position of baffle plate 53, and this pressure is applied to a diaphragm 31 to actuate a baffle 32 which varies the flow from nozzle 22 and sets up a variable back-pressure in the line 21 supplying the nozzle 22. This back-pressure is applied to a chamber 10 of the second amplifier where it acts on a diaphragm 9 carrying a tube 8. The lower end of the latter coacts with a hinged plate 4 to provide an exhaust valve for a chamber 11, an inlet valve to chamber 11 being provided by the plate 4 which coacts with a nozzle 3 connected to the supply line 1; and the resultant pressure in chamber 11 is applied to a motorised valve 18 to regulate the value of the variable. The nozzles 27, 28 are carried on one limb of a ]-shaped member 35 which can pivot around a pin 41; and the member 35 is rotated to give a restoring action by applying the control pressure produced in line 21 to a bellows 37 acting against the connecting arm 36 of member 35. By varying the position of pin 41 relative to arm 36 by rotation of a knob 43, the proportional band of the system can be varied. By interconnecting bellows 37 with an opposing bellows 38 through a throttle e, the proportional regulation provided by the unit is given a progressively decreasing proportional factor. The whole amplifier unit is rotatably mounted on a member 46, and by adjustment of a knob 48, the unit is rotated relatively to baffle-plate 53 to set the datum value of control. The datum thus set is indicated by a pointer 49. Derivative and integral factors are introduced into the control by allowing the pressure in line 21 to have access to chambers 57, 60 on opposite sides of a diaphragm 61, the connections including derivative and integral throttles 56, 59, respectively. Diaphragm 61 is also connected to valves 3, 4, 8 through oppositely hinged levers 65, 14 which are interconnected by a link 67, the latter being adjustable in position along the levers.

Title: Improvements in or relating to the Manufacture of Cigars and Similar Tobacco Smoking Articles
IPC: A24C3/00
Filed: 1966-01-28
Abstract: 1,170,791. Cigar-making machines. MOLINS MACHINE CO. Ltd. and D. W. MOLINS. 27 Jan., 1967 [28 Jan., 1966], No 3996/66. Heading A2C. [Also in Division F2] In an apparatus for producing a continuous wrapped tobacco rod for manufacture into cigars or similar smoking articles a continuous stream of tobacco formed in conventional manner on the underside of a suction-backed pervious conveyer 4 is fed lengthwise on to a constant speed continuous web 6 of wrapper material (which may be reconstituted tobacco) while continuing its lengthwise feed, and the speed of the stream feed is periodically varied relatively to the web to attenuate the stream at intervals spaced along its length. The variation of the tobacco stream speed is effected by varying the speed of a pulley that drives the conveyer 4. A constant speed drive is applied through a gear 23 to a shaft 17, and this shaft 17 carries a worm 18 axially slidable therealong which drives a worm wheel 19 fixed to a pulley 8. Cyclical movement of the worm 18 to the left and right (as seen in Fig. 1) along the shaft by means of a cam 20 and cam roller 21 against a return spring 22, cyclically varies the speed of the pulley 8. The cam 20 is shaped so as to effect a speed variation of the conveyer 4 that will, after the removal of surplus tobacco by a trimmer disc 10 cooperating with a rotating member 11, produce a tobacco stream having relatively long sections of normal uniform density separated at regular intervals by relatively short lengths having an attenuated density, the overall length of each normal plus attenuated section being approximately equal to the length of one or two cigars according to whether both or only one of the cigar ends is required to be tapered. The wrapping of the tobacco stream and subsequent processing to produce cigars is affected in conventional manner.
