Title: Improvements relating to measuring devices for machines for winding or reeling yarn upon swifts
IPC: B65H63/08
Filed: 1924-02-15
Abstract: 212,529. Maschinenfabrik Schweiter Akt.-Ges. March 10, 1923, [Convention date]. Reeling-machines; stop-motions - Relates to reeling-machines wherein the swift is mounted on an arm and the stop-motion is automatically operated after a predetermined number of revolutions of the swift or after a predetermined travel of a measuring screw. The swift is carried in an arm 2 which, upon completion of the winding and the stopping of the machine, is manually moved so as to disconnect the measuring-gear and to allow it to be automatically returned to its initial position. The measuring-gear is driven from a pin on the pinion 5<1>, which is mounted on a shaft 6 and drives the swift, by gearing 31 - - 35, and comprises a screw 37 which is screwed into a bracket 38 loosely pivoted on a shaft 20. A pin 42, Fig. 1, on the outside of a drum 39 on the screw engages an arm 21 of a lever loose on the shaft 20, when the screw has been traversed in accordance with the desired length of yarn, and so operates a spring- controlled lever 13, Fig. 4, which releases the tension lever 11 of the driving-band. As the lever 11 falls, a bowl 17, which is normally engaged by a catch on the arm 14 of the lever 13, presses the arm 14 so as to apply a brake 22 to the interior rim of the driving-pulley 8, and the lever 21 raises a spring-controlled rod 23 so as to cause a catch 27 to snap behind a catch-pin on the lever 11 and hold it in the inoperative position. When the arm 2 is swung forward to remove the skein a rod 55 turns the shaft 20 which, as it passes the dead point, is snapped over by a spring, and, by means of a cam 57, moves the bracket 38 so that the measuring-screw 37 is disconnected from its driving-gear 35, whereupon a weighted cord 44 wound around the drum 39 returns the screw to its initial position. When the arm 2 is returned the shaft 20 is moved in a contrary direction by the rod 55, and the spring snaps it back into its original position and a cam 58 operates the bracket 38 so that the screw is again engaged with its driving-gear. The lever 21 is brought into its initial position and the rod 23 lowered, whereupon the catch 27 is freed and the lever 11 released. To set the apparatus to wind the desired length, a stop 43 on the inner flange of the drum 39 engages, in the initial position of the measuring-screw, with a pin 46 adjustably mounted on a pointer 50. A scale 5 on the bracket 38 enables the measured length to be read, the measuring being from the desired number of metres to the zero point. The lengths indicated by the scale may be varied by varying the gearing of the screw. The threadguide of the machine is operated by chain-gearing 69, 70. A second swift, mounted on an arm on an extension of the pin 4 and connected to the arm 2, may be operated by a wheel similar to the wheel 5<1> on the opposite end of the shaft, one measuring device serving both swifts.

Title: Improvements in methods of producing electric lamps with high pressure gas fillings
IPC: H01J9/395
Filed: 1937-02-10
Abstract: 473,863. Discharge apparatus. AKTIEBOLAGET HAMMARBYLAMPAN. Feb. 10, 1937, No. 4029. Convention date, Feb. 11, 1936. [Class 39 (i)] [Also in Group XI] In a method of filling electric incandescent lamps and discharge tubes with a gas which, even when the lamp is not in operation has a pressure exceeding atmospheric pressure, the pressure within the lamp during the sealing operation is kept lower than or substantially equal to the surrounding pressure. The lamp bulb may be evacuated by a vacuum pump, filled with gas and then cooled so that the contained gas is liquefied or solidified, the sealing next being carried out in the usual manner by heating the glass until it is softened sufficiently for the pressure of the outer atmosphere to press the walls of the stem together at the sealing point. The pressure within the lamp is subsequently increased by warming the lamp. The cooling may be effected by using liquid air in the manufacture of lamps containing Krypton or xenon or a mixture of those gases at high pressure, while liquid nitrogen is preferable in the production of high pressure argon lamps. Alternatively, liquid hydrogen or liquid neon may be used. The condensation of the filling gas may be carried out in a separate cooling plant and the condensed gas then supplied to the lamps through a heat-insulated conduit. The gas may also be supplied to a lamp by introducing therein a substance containing the gas in chemical or mechanical combination whereby, after sealing the lamp, the gas is liberated, for example by heating. Examples of such substances are the nitrides of alkali or alkaline earth metals, such as NaN3. For the production of hydrogen at high pressure in an electric discharge tube the hydride of lithium may be used which, upon heating, will liberate hydrogen.

Filed: 1943-03-15
Abstract: 579, 848. Bomb dropping sights. RICHARDS, D. A. March 15, 1943, No. 4229. [Class 92 (ii)] The release point in bomb-dropping is determined by continuously viewing the target against a background moving in the same direction as the apparent movement of the target, the speed of the background being preset or adjusted in accordance with the height and speed of the aircraft to represent the critical angular velocity of the sight line which exists at the release point. In the form shown, the target is viewed in the direction of the arrow 3 through a transparent mirror 1 stabilized for pitch by a 2 : 1 linkage with the gimbal ring 7 of a gyroscope 8. The background is formed by the reflection in the mirror 1 of an illuminated line 10 on a revolving drum 9, viewed at infinity after reflection from a parabolic mirror 12. The angular velocity of the line 10 in the field of view is adjusted by a constant-speed motor 13 driving the drum 9 through a friction disc-and-roller variable-speed gear, the roller 17 of which is moved radially of the disc 18 by a screw 23. This screw is rotatable by a handle 24 that adjusts a pointer 26 to the appropriate speed line on a drum 27 rotated by a handle 28 to set the drum to a height scale registering with a fixed pointer 29. The release point is determined, during the approach to the target, when the angular velocity of the apparent motion of the target increases to a value corresponding to the preset critical angular velocity of the illuminated line, there. being then no apparent movement between the line and the target.
