Filed: 1919-12-24
Abstract: 160,908. Lewis, A. Dec. 24, 1919. Spring power-storing mechanism.-The spring motor of a sound recording or reproducing machine is connected to the turntable spindle by a worm shaft and friction discs, and the speed rate of the friction gear is automatically and gradually reduced as the force of the spring is expended. As shown in Fig. 1, the spring drum carries a worm wheel a<5> driving a worm c on a shaft c<1>. This shaft is inclined and is movable axially under the control of a compression spring c<4>. A friction disc d on the shaft c<1> engages the face of a disc d<1> which rotates with the turntable shaft e but is axially movable thereon against the action of a spring f. At starting, when the torque of the motor spring is at its maximum, the springs c<4> and f are compressed and the disc d engages the disc d<1> near its centre. As the torque decreases, the worm c moves towards the right, the disc d drives the the disc d<1> nearer its rim. The motor is wound by a handle on the shaft a<4>, which is prevented from reverse rotation by a spring grip. The bearing b for one end of the motor spindle a<1> is removable, and the frame b<1> is slotted at b<2> to allow the spindle to be removed.

Title: Improvements in or relating to the production of artificial filaments, yarns or threads
IPC: D01F2/28
Filed: 1932-11-17
Abstract: <PICT:0410511/IV/1> <PICT:0410511/IV/2> A plurality of artificial filaments are extruded and drawn all at the same varying linear speed so as to impart similar variations in denier to each filament, and associated as a thread, the lengths of filaments between the different spinning orifices and the point of association of the filaments being different, whereby corresponding variations in the different filaments occur at different places in the length of the thread.  The <PICT:0410511/IV/3> filaments may be extruded in groups from points which lie at different distances from the point of association.  The drawing of the filaments at varying linear speeds may be accomplished by any of the methods described in the parent Specifications and may be applied continuously with the production of the artificial filaments either by the wet coagulation or dry evaporative method. In Fig. 1 a spinning cell 10 is fitted with a number of supply pipes, filter candles, and jets 13, the latter being arranged at different levels.  The groups of filaments are associated at the point 15 and all drawn similarly at varying linear speeds by the feed roller 18 and the three-armed member 23.  Instead of the group of jets 13, there may be used a single dome-shaped jet having the spinning orifices 25 disposed in a spiral, as shown in Fig. 3. Again, as in Fig. 6, there may be used an inclined jet having the spinning orifices 33 arranged in a straight line. Inclined jets may also be employed in the arrangement of Fig. 1, the most convenient position being with the highest orifice of one jet at the same level as the lowest orifice of the next jet, and so on.  A particular application of the threads produced is in the process of Specification 403,738, [Group IX], according to which artificial staple fibres are produced by stretching to breaking point a yarn having variations in denier along its length, the variations being of a frequency corresponding to the length of staple fibre desired.

Filed: 1946-11-01
Abstract: 617,746. Spray carburetters. ARVASTSSON, O. A. Nov. 1, 1946, No. 32524. [Class 7 (iii)] A carburetter for internal combustion engines comprising a mixing chamber having a main air inlet and an outlet for connection to the engine intake manifold, a fuel nozzle opening into the mixing chamber and communicating with a float chamber, a heating chamber fitted with heating means and surrounding the float chamber and having an air inlet and an outlet which latter opens into the mixing chamber, is provided with a tubular member which constitutes the air outlet from the heating chamber and surrounds the fuel nozzle in the mixing chamber so that the heated air flowing from the heating chamber vaporizes the fuel from the nozzle and mixes therewith before the mixture formed mixes with the air flowing into the mixing chamber through the main air inlet thereof. Fuel enters the float chamber 1 through a valve 8 under the control of the float 9. The heating chamber 10, with an air inlet 11, is fitted with electrical element heating 12 and has an air outlet opening into the mixing chamber 2. The heating chamber 10 can also be heated by exhaust gases which flow in a channel 13, arranged externally of the former and provided with an inlet 14 and an outlet 15. From the float chamber 1 the fuel passes through a passage 16 and an adjusting valve 18 to nozzle 17, which projects centrally from the base of the mixing chamber 2. The heating chamber 10 has an extension 19 in the top wall of which is formed the tubular member 20 that surrounds the nozzle 17 in addition to extending above it, thereby forming the outlet into the mixing chamber 2 for the air from the heating chamber 10. The electrical heating elements 12 are only intended to be used before and during starting of a cold engine. During normal engine operation the air in the heating chamber 10 is heated by the exhaust gases which flow through the channel 13 around the heating chamber 10, the fuel in the float chamber 1 being also heated at the same time. The air from the heating chamber 10 enters the mixing chamber 2 at the base of the tubular member 20 and passes the nozzle 17, thus vaporizing the fuel before this mixture combines with the air entering through the main inlet 3. In a modification an additional fuel passage 21 may branch off from the nozzle fuel passage 16 and communicate with the mixing chamber 2 through a suitable control valve 22.
