Title: Improvements in or relating to machines for manipulating cut tobacco
IPC: A24C5/34
Filed: 1953-03-16
Abstract: 785,589. Cigarette - making machines. MOLINS, D. W., POWELL, G. F. W., and MOLINS MACHINE CO., Ltd. June 16, 1954 [March 16. 1953], No. 7201/53. Class 130. [Also in Group XXXV] In a machine for manipulating cut tobacco, variations in the mass per unit length of a moving tobacco filler are automatically corrected by an electrical signal, responsive to such variations, which controls the distribution of tobacco on to an endless conveyer whose speed at the delivery end is constant. In a cigarette making machine, Fig. 1, tobacco is showered from a hopper @ to a hopper tape 2 @  succession by @elt @ eyers 4 and 6. Thereafter it passes down a sloping passage 11 as described in Specification 646,746 and is delivered on to a cigarette paper web 12 moved by a garniture tape 13. To effect the long-term correction, the output of a radioactive detector 15, which is dependent on the mass per unit length of the tobacco on tape 13 is applied to an amplifier and feedback filter 16 so as to control, through a variable-speed oil unit 19 a differential gear 23 in the drive between a motor 22 and tape 13. Still longer-term variations are effective through a filter circuit 17 to produce additional correction by controlling, through a relay 21 and a solenoidoperated ratchet device 20, a variable speed pulley 18 in the drive between motor 22 and hopper 1. To effect short-term correction, the output of a further radio detector 5 associated with a short length of the tobacco stream near its point of delivery on to conveyer 6 is applied through a feedback thermionic valve amplifier 24 to control one of a cathode-coupled pair of thermionic valves in a filter stage 25 controlling differential moving coils 67 operating a valve 68 of an hydraulic unit 69 controlling a differential gear 9 in the drive between pulleys 7 and 8 of conveyer 6. Since pulley 8 is directly driven by motor 22 the speed of pulley 7 is thus varied to alter momentarily the rate of supply of tobacco on to belt 6. Although metal teeth (not shown), bonded on to the inner surface of the belt, engage with grooves on pulleys 7 and 8, momentary difference in speed of the pulleys is possible because belt 6 is elastic, being of rubber, plastic or canvas and rubber. The output of a potentiometer 70, operated with differential gear 9, is applied through an integrating circuit to control the other valve in stage 25 in a sense tending to prevent excessive movement of differential gear 9. In a modification, Fig. 6 (not shown), belt 6 runs at constant speed and the point at which tobacco is fed to it is adjusted to effect the short-term correction. An alternative arrangement in which the long-term variations are correction before the short-term variations is referred to. Use of scintillation counters instead of ionization chambers is referred to. Specifications 781,041, [Group XXXV], 781,042, 785,590 and 785,591, [Group XL (a)], also are referred to.

Title: Process for polymerizing olefins
IPC: C08F2/00
Filed: 1957-03-08
Abstract: Olefins are polymerized in the presence of a Zeigler-type catalyst in the presence of an aliphatic hydrocarbon containing 2 to 4 carbon atoms and which is gaseous at room temperature and normal pressure by effecting the polymerization at a pressure above atmospheric pressure whilst maintaining the partial pressure of the dispersing media in the gaseous phase at between 20 and 40% of the total pressure.  The polymerization heat is preferably eliminated by cooling the gaseous phase, which is mechanically moved, e.g. in a circuit by a ventilator blower or compressor means and effecting the cooling at the pressure side of such a means.  The olefin may be continuously or intermittently introduced into the polymerization vessel.  The dispersing medium may be ethane, propane, butane, or isobutane, or mixtures thereof. There may also be used mixtures of one or more of these hydrocarbons with benzene, toluene, xylene, decahydronaphthalene or a saturated hydrocarbon boiling between 80 DEG  and 230 DEG  C.  The olefins polymerized may be ethylene, propylene, butylene, isobutylene, 1-hexene, 1-octylene, or mixtures thereof, in particular ethylene and propylene.  Exemplified catalysts are aluminium triethyl and titanium tetrachloride or trichloride. Specifications 799,392, 799,832 and 801,031 are referred to.

In a control system for an asynchronous electrical machine, a reversible electric motor regulating the slip resistance is automatically controlled by a relay responsive to the power input to the machine when motoring and is automatically controlled by another relay responsive to the output of a tachometer generator during braking. In the Figure the stator of a wound-rotor asynchronous motor M is supplied during motoring from a three-phase source T through a reversing switch I and a switch G. A wattmeter associated with the motor input controls, through a two-way relay W the input to equipment A controlling a servomotor m adjusting cam-operated contacts c to vary in steps resistances R in the rotor circuit of the controlled motor. Rotor resistance is thus increased with increase of input power to reduce speed and increase motoring torque. Motoring in either direction is initiated by movement of a lever L in the appropriate direction to operate reversing switch I and energize the centre contact f2 of relay W. When braking, the stator is supplied from a D.C. source U through switch G. A tachometer generator D driven by the controlled motor then controls through a two-way relay E the input to equipment A so that servomotor m increases resistance R with increase of motor speed to control braking torque. Re-balancing of relay E upon a change in speed is effected by adjustment of resistances r by motor m simultaneously with resistances R. Braking is initiated by movement of a lever F to operate switch G, energize the centre contact a1 of relay E1 and set rheostats rl, r2, controlling the D.C. excitation of the controlled motor and the excitation of the tachometer generator in opposite senses, so that braking torque is dependent on the setting of lever F.
