Title: Improvements in or relating to cigarette making machinery
IPC: A24C5/39
Filed: 1930-09-04
Abstract: 361,998. Cigarette-making machines. IMPERIAL TOBACCO CO. (OF GREAT BRITAIN & IRELAND), Ltd., East Street, Bedminster, and COATES, A. F., Codrington Grange, Broadway Road, both in Bristol. Sept. 4, 1930, No. 26367. [Class 130.] In a continuous-rod machine, the stream or part of the stream of tobacco passing to the moving paper web is diverted by striking against a movable counterbalanced element, the deflections of which control the speed of the tobacco feeding mechanism. As shown in Fig. I, tobacco is removed from the carded roller 3 of a hopper 1 by a picker roller 5 and fed by a belt 6 to a spiked roller 7, a concave shield 54, and a picker roller 8, by which it is showered into a trough 10 leading to the paper web 11. The element 9, counterbalanced by a weight or a spring, is pivoted at 12 and provided with a contact 14 movable between fixed electric contacts 15, 16 connected to solenoids 18, 19 for controlling the drive of the carded feed roller 3. The latter is driven through bevel gearing 25, 27 from a shaft 24, which is connected to a shaft by coned pulleys 21, 23 and an adjustable belt controlled by a fork 48 adjusted by a screw shaft 46. The adjustment is effected by a toothed wheel 34 connected by bevel gearing to the shaft 46 and actuated from the shaft 20 by means of bevel gears 28, 29, a crank 30 and connecting rod 31, and an arm 32 carrying pawls 35, 36. These are normally held out of engagement with the toothed wheel 34 by arms 39, 40 connected to the plungers 41, 42 of the solenoids 18, 19. On the deflection of the element 9 and the actuation of one of the solenoids, the arm 39 or 40 is displaced and the pawl 35 or 36 drives the wheel 34 until the speed of the feed roller 3 is adjusted and the element 9 returns to its mid position. In modifications, the tobacco falls directly from the belt 6 on the counterbalanced element 9 ; the element 9 controls the speed of an electric motor that drives the tobacco feeding-mechanism ; the element 9 intercepts only a part of the tobacco stream, and the counterbalancing means, such as a spring, acting on the element 9, is adjustable by an element which may be controlled by variations in humidity. The element 9 may be damped by a, Jiuid dashpot. Fig. 3 shows a modification in which feed rollers 49, 50 are employed in place of belts and the tobacco stream impinges on a baffle 52 before encountering the counterbalanced element 9. The provisional Specification states also that the movable counterbalanced element may actuate means for adjusting the speed of the moving paper web on which the tobacco is deposited ; or the element may actuate an indicating device to enable the operator to adjust the speed of the tobacco feeding-mechanism or of the moving paper web in accordance with the indicator readings. It is also stated that the operation of the electric circuits may be effected by beams of light acting on photo-electric cells or other light-sensitive elements.

Abstract: 919,590. Writing instruments. HOFMANN, U. July 25, 1961 [Aug. 2, 1960], No. 26818/61. Class 146 (3). A multi-colour retractable writing instrument provided with a known press knob and detent mechanism includes a connecting element subject to the force of gravity in the sense that when the instrument is tilted from the vertical, the connecting element provides a connection between a particular cartridge or writing unit to be used and the press knob mechanism. On actuation of the mechanism, the writing unit selected is moved into the writing position. In one embodiment, Fig. 3, the inner part of a ballpoint pen is shown removed from its housing. The selection of a desired cartridge or writing unit 13 takes place in a chamber 20 situated in the upper part of a cage 9. The chamber is closed by a top plate 27, on which rests a spring 25 for a conventional press knob 1. The connecting element in this embodiment is a ball 28, free to take up any position in the chamber 20. Each of the three writing units 13 is secured in a carrier 14 provided with a hollow guide part 15, Fig. 5. The knob 1 has extensions 19, and each extension can slide into its respective guide part 15. The connecting element or ball 28 can be positioned by tilting the pen so that a positive connection is provided between an extension 19 and a guide part 15. On depression of the knob 1, a particular writing unit is moved forward. Various other embodiments are shown using exactly the same principle, and in Fig. 11 (not shown) the ball 28 is always biased above a particular writing unit (such as the blue colour). In a further form of the invention, the connecting element is a rod or drop lever, one end of which is pivotally secured inside a cavity in the press knob, and the other end allowed to take a position required above a particular writing unit carrier, simply by tilting the pen. On depressing the knob 1, a positive connection is provided between the carrier and press knob. A modification is shown where the rod or knob lever is biased above a particular writing unit carrier simply by pivotally securing the rod off centre in the press knob. Two embodiments of the known press knob mechanism are given. In one embodiment, Fig. 1, a ball 3 is situated half way in a cam groove 2 of the knob 1, and the other half runs in an annular groove 4 of the pen casing. In Fig. 2 (not shown), the second embodiment has the annular groove on the press knob and the cam in the pen casing.

Title: Improvements in heaters for use in connection with the cooling systems of internal combustion engines
IPC: F28D1/00
Filed: 1949-10-19
Abstract: 665,061. Automatic temperature control systems. BERGER, G. J. O. WELIN-. Oct. 19, 1949 [Oct. 20, 1948], No. 26866/49. Class 38 (iv). [Also in Groups XI and XIII] A heater for the liquid in the cooling system of engines of the type having a liquid chamber heated by a burner which is lighted and extinguished automatically in dependence on the cooling liquid temperature and that of the burner flame or flue gases includes an electromagnet, controlled by a thermostat responsive to the cooling liquid temperature. having an armature connected with a valve controlling the fuel supply to the burner. As shown in Fig. 1, fuel from a tank A passes through pipe 3 to a float-operated level control valve C and thence through a pipe 12 to the eleetromagnetically-controlled valve 14. The fuel then passes via a pipe 17 to the wick 19 of the burner E. The burner E has a heating coil 20, igniting resistance 24, and water circulating coil 30 to which water is delivered via a pipe 27 and thermostat G housing 29. The fluegases are taken off from a duct 34 housing a second thermostat H. The electromagnet D has three pairs of contacts 49, 50, 51, the thermostat G has a bimetal strip 56 operating between fixed strips 54, 55 and the thermostat H is adapted to operate a movable contact 62 between fixed contacts 63, 102. To start the burner from cold a switch 73<SP>1</SP>, Fig. 4, is closed, thereby completing a circuit over contacts 54, 56 of the thermostat G and electromagnetic contacts 51 to the coil 39, thereby pulling up the armature 42 and opening the valve 14. The electromagnet is retained in the position to which it is moved by a spring 52. Movement of the armature breaks contacts 51 and closes contacts 49, 50, completing, over contacts 49 and contacts 62, 63 of the thermostat H a circuit to the heating coil 20 and igniting resistance 24. As the flue gases become hot the thermostat H moves contact 62 to contact 102 to complete a circuit to an indicating lamp 106 and as the water warms, contact 56 of thermostat G is moved towards fixed contact 55. Upon closure of contacts 55, 56 the coil 40 is energized over contacts 50 to pull down the armature 42 thereby closing the fuel valve 14, opening contacts 45, 50 and closing contacts 51. As the boiler is then extinguished contact 62 again moves to co-operate with contact 63 and a fresh cycle of operation is started when the water has cooled sufficiently to allow contact 56 to operate again with contact 54. In a modification, the bimetal strip 35 of the thermostat H instead of being directly responsive to the temperature of the flue gases may be external to the burner and placed in close thermal relation with a conductive metal strip itself having one end in the burner gases. The burner may also have an annular wick and central draft column.

Title: The resolution of 3-hydroxy-and 3-methoxy-n-methyl-morphinanes and process for the manufacture of the latter
IPC: C07D221/28
Filed: 1950-11-03
Abstract: A method of preparing optically active 3-hydroxy and 3-methoxy-N-methyl morphinanes comprises converting racemic 3-hydroxy and 3-methoxy-N-methyl morphinane into their salts with an optically active acid, separating the salts into their optical antipodes by fractional crystallization and thereafter, if desired, basifying said antipodes and converting the free bases so formed into the required salts by treatment with the appropriate acid.  Where the optically active 3-hydroxy compounds are obtained they may be methylated as free bases to the 3-methoxy compound and if desired converted to salts.  Alternatively, the racemic 3-hydroxy compound may be methylated before resolution. D-tartaric acid is specified as a suitable optically-active acid. Phenyl - trimethyl - ammonium hydroxide may be used as methylating agent.  Water is a suitable solvent in which to effect the resolution.  To prepare (-)-3-methoxy-N-methyl morphinane crystallization of the D-tartaric acid salt may be used, the desired compound crystallizing out first, then methylating the product.  (+)-3-methoxy-N-methyl-morphinane may be obtained by methylating the racemate followed by crystallization of the D-tartaric acid salts.  In examples: (1) and (2) both these procedures are employed.  Hydrobromides and hydroiodides of the 3-hydroxy-and 3-methoxy-compounds are prepared.
