Abstract: 916,141. Cigarette - making machines. MOLINS MACHINE CO. Ltd. March 20, 1959 [March 21, 1958], No. 9091/58. Class 130. In means for forming a tobacco filler by conveying tobacco particles in an air stream through a passage 12, Fig. 3, on to a conveyer band 20, a portion of the air stream is drawn off through a side opening 33. The tobacco particles, thrown off a card drum 1, Fig. 1, by a picker wheel 3, are deflected towards the passage 12 by a perforated suction drum 7 connected through a dust separator 44 to a fan 43. A high velocity air stream is set up in passage 12 by a suction box 25 situated above the perforated band 20 and connected to fan 41 and by a suction box 32, Fig. 3, connected to the side opening 33 which is covered by a grill with rearwardly sloping openings 34. The outlet of the fan 43 discharges into a diffuser chamber 48 from which the air escapes through a perforated grill 50 back towards the passage 12. The outlet of fan 41 passes through a dust separator 55 and cyclone separator 53 to atmosphere, some of the separated dust being fed through a pipe 56 into the chamber below band 20. In a modification, Fig. 5, the air stream feeds the tobacco downwardly on to an unperforated conveyer band 74, all of the air escaping through side openings 75 to a suction chamber 76. The band 74 may alternatively be perforated and a suction chamber provided beneath the band in addition to suction chamber 76. Specifications 764,551, 854,736, 895,733 and 909,222 are referred to.

Title: Improvements in and relating to Electric Motor Control.
IPC: H02P5/685
Filed: 1917-06-29
Abstract: 114,246. British Thomson - Houston Co., (General Electric Co.). June 29,1917. Systems for continuous-current motors only.- In a system for control of a number of motors driving separate wheels of a vehicle, automatic means de-energize all the motors if one motor becomes de-energized, but the means are rendered inoperative during the transition from series to parallel. The motors M<1>, M<2> are supplied from the generator G, and the contacts of the circuitbreaker CB are included in the circuit. The tripping latch 3 of the circuit breaker is controlled by two coils 1, 2 which neutralize each other when both are energized. When the controller is moved to connect the motors in series the coils 1. 2 are included in series in the circuit. As the controller is moved to make the parallel connexion, the motor M<1> and the coil 1 are short-circuited and the coil 2 is shunted by the resistance 4 so that the circuit-breaker does not open. In the parallel position, the coil 1 is in circuit with the motor M<1> and the coil 2 with the motor M<2>, and any substantial change in the energization of either motor will cause the circuit-breaker to open.

Title: Polyurethanes derived from 1,4-diethylbenzene ª‰,ª‰'-diisocyanate
IPC: C08G18/76
Filed: 1966-03-03
Abstract: Elastomeric polyurethanes are prepared by reacting a diisocyanate composition containing a major proportion of 1,4-diethylbenzene-b ,b 1-diisocyanate with a polymeric polyol having an hydroxyl number of 35 to 450 and a difunctional active-hydrogen containing chain extender other than water.  The polyisocyanate used is suitably 100% 1,4-diethylbenzene-b ,b 1-diisocyanate but up to 40% by weight of said diisocyanate may suitably be replaced by an aliphatic diisocyanate.  Suitable polymeric polyols are essentially linear polyethers, polyesters and polyesteramides. The chain extending agents may be hydrazine, organic diamines, glycols and amino alcohols.  Preferred methods of preparing the polyurethanes are (a) reacting an excess of the polymeric polyol with the diisocyanate to form a hydroxy terminated prepolymer which is then reacted with an excess of diisocyanate to form an isocyanate-terminated prepolymer which later prepolymer is chain extended with the above mentioned chain extenders or (b) preparing the isocyanate terminated prepolymer direct and then chain extending.  The chain extending reaction may take place in the presence of a solvent or alternatively the prepolymer may be extruded in the form of a filament through a bath containing a solution of the appropriate extender.  If a chain extender is used which contains unsaturated side chain groups the resulting polyurethane may be cross linked with e.g. sulphur.
