IPC: B61L1/10
Filed: 1959-08-20
Abstract: 922,764. Transistor circuits. COMPAGNIE DE SIGNAUX ET D'ENTREPRISES ELECTRIQUES. Aug. 20, 1959, No. 28550/59. Class 40 (6). [Also in Groups XXX and XXXVI] In train detecting apparatus (see Group XXXVI) a two state circuit comprises a transistor 19 biased to saturation by a supply 20 so that no output is fed to load 25 (which may be a relay) until the peak value of the alternating input voltage V exceeds that of supply 20. The transistor is then swung out of saturation to provide an output, part of which is rectified at 26, smoothed by capacitor 27 and fed back to the base to overcome the bias from supply 20, thus driving the circuit into its second (back biased) state. The circuit remains in this state until the input voltage V falls to a much smaller value, when it is reset to its saturated state. Input voltage V may be supplied via a saturated transistor amplifier (Fig. 12, not shown), so that the effective input is never sufficient spontaneously to drive the circuit out of saturation. The circuit is then triggered to the back-biased state by connecting points α and #.

Title: Improvements in the manufacturing of artificial filamentary materials
Inventor: BROWN RUSSELL JACQUES
IPC: D01D10/04
Filed: 1953-10-19
Abstract: <PICT:0787560/IV (a)/1> In wet-spinning, the freshly formed filaments are given a preliminary wash by alternately passing them several times round a pair of skew rollers at least one of which is partly immersed in a washing liquid, one or both the rollers having a pressure roller bearing thereon above the surface of the washing liquid.  The process is particularly useful in the wet-spinning of an acetone solution of cellulose acetate into an aqueous solution of diethylene glycol diacetate as coagulant, one passage of the filaments through such a bath before collection being sufficient to reduce the content of coagulant to below 30 per cent (calculated on the dry weight of the filaments), whereby individual filaments have no tendency to adhere together. Filaments may be passed through a succession of such baths, e.g. 15-25 baths each containing a pair of skew rollers round which the yarn passes 3-10 turns, such washing treatment lasting about 5 mins. and reducing the content of diethylene glycol diacetate to less than 1.5 per cent.  When a succession of washing baths are used, each may be supplied continuously with fresh water, or only the last few baths may have a fresh water supply which then flows through the other baths in counter current.  Alternatively, after passage through a single washing bath according to the invention, the filaments may be wound up in a centrifugal box, and the cake formed, preferably still in the box, either soaked several times for 30 minutes a time in water below 40 DEG  C., or washed in running water.  As shown, filaments spun from the jet 2 are drawn up the setting tube 7 by godet 13, which may be fluted, entrained liquid being removed by pigtail guide 12 and inverted funnel 11 into the collecting head 10.  The filaments then pass several times round the pair of skew rollers 18 partly immersed in the washing bath 14.  Resting on the first roller 18 is a pressure roller 19 carried by supporting arms 20 which are freely pivoted to a bracket 21 attached to the bath.  Specifications 720,187, 787,556, 787,557, 787,558, 787,559, 787,562 and 787,564 are referred to.

Title: Improvements in protective devices for commercial oil heating systems
IPC: F28F27/00
Filed: 1933-10-18
Abstract: 414,548. Electrically-actuated valves. KESTNER EVAPORATOR & ENGINEERING CO., Ltd., 5, Grosvenor Gardens, Westminster. Oct. 18, 1933, No. 28812. Convention date, Jan. 19. [Class 135.] A heating system employing circulating oil is provided with protective mechanism to prevent overheating, comprising means responsive to the circulation pressure combined with means responsive to the oil temperature, whereby the heating means is controlled. A fuel burner 4 is supplied by a pipe 5 through a valve 6, and heats a coil 7 through which the oil is forced by a pump 8 to a heat exchange device and thence back through pipe 12. An expansion tank 15 is provided. A pressureoperated switch 16 is connected to the two ends of the coil 7, and a thermal switch is subject to the temperature in the pipe 11. Fig. 2 illustrates the control circuit, which comprises a solenoid-operated fuel control valve 29, 31, relay switch 35, pressure-operated switch 50, thermal switch 22 and hand switch 28. When the pump 8 is started and circulation established, the switch 50 is opened, and the hand switch 28 is then closed to complete a circuit through solenoid 39 and close switches 35, 40. Solenoid 31 is thereby energized and the fuel valve opened. The two switches 22, 50 are normally open, but if either is closed due to defective circulation or overheating of the oil, the relay 39 is short-circuited and switches 35, 40 opened so that solenoid 31 is de-energized and valve 29 is closed. The supply of fuel cannot be restored by the hand switch 28 until normal circulating pressure and temperature have been restored, but closing of the hand switch is necessary to open the fuel valve after switches 22, 50 are opened.

Title: Improvements in speed controlling mechanism for ring spinning frames and the like
IPC: D01H1/24
Filed: 1921-10-31
Abstract: 191,519. English Electric Co., Ltd., and Darlington, W. E. Oct. 31, 1921. Driving - arrangements.-In speed con. trolling mechanism foi ring spinning frames &c., the control member is driven by or in definite relation to the part whose speed is tc be controlled. The shaft 1 is driven from the part of the machine to be controlled, and carries thereon a ring 3, a single tooth gear 23, and a sliding sleeve 17 capable of being actuated by a lever 19, the other end of which is moved by a slide 43 reciprocated by rack gearing and bevel gearing 40, 38 from a countershaft 30. This countershaft is driven either directly from another countershaft 22 through a gear 25 and sliding gears 33, or indirectly for reversal through gears 26, 27, 29, 34, a neutral position for the sliding gears 33, 34 being provided, so that the shaft 30 may be rotated directly by hand. The countershaft 22 is driven by a gear 24 from the single tooth gear 23 on the shaft 1. The member for controlling the speed comprises a reverse-screwed shaft 49 and two non-rotatable screw sleeves 52, this member being reciprocated from a connecting-rod 54 and an automatically adjustable crank pin 6 on the ring 3 and rotated through gearing 39, 45, 47, 48 from the shaft 30. The gradually increasing throw of the crank 6 away from the controlling-rod 49 is compensated by the automatic gradual unscrewing of the rod 49 in the screw sleeves 52, so that a gradually increasing amplitude of reciprocation is obtained in a direction only on one side of the ring 3. The position of the crank-pin 6 is varied by mounting it on a non-rotatable screw sleeve 8, Fig. 5, adapted to be actuated by a screwed rod 5 driven continuously through gears 13, 12, 14 from a gear 15 on a sleeve 16, a roller 57 on which engages a spiral cam slot in the sliding sleeve 17 on the shaft 1. As the shaft 1 and ring 3 rotate and the sleeve 17 slides along, the sleeve 16 is rotated relatively to the shaft and rotates the screw 5. In order that the sleeve 17 may be changed, a bolt 55 is unscrewed and the ring with the gears 12, 13, 14 is removed bodily, the sleeves 16, 17 being then easily removable.

Abstract: 658,206. Filling fountain pens. HUCKLE, A. Nov. 8, 1948, Nos. 28931 and 32163. [Class 146 (iii)] Apparatus for filling the reservoirs of ballpointed fountain pens comprises a container 11 in which viscous ink is under gaseous fluid pressure, and one or more valve-controlled outlets for the ink provided with either a feeding nozzle 24 shaped to make inktight connection with the reservoir of a pen, or with a delivery tube of dimensions such that it can be inserted with a sliding ink-tight fit into the reservoir. A tube 19 is connected between an elbow fitting in the outlet of the container and a valve 22 operable by a lever 23. As shown the valve has attached thereto a removable nipple, forming the nozzle 24, provided with a conical bore to receive the writing end of a ball-point pen reservoir from which the ball has been temporarily removed. In a modification, the nipple is integral with a long tube which can extend from the back end of a reservoir or cartridge to a point near the writing end ; in this case the ball writing point need not be removed. When the nozzle shown in Fig. 2 is used, a rod-like indicator 43 in the end cap 45 is inserted into the end of the reservoir ; movement of the cap 45 away from the end of the reservoir indicates that the latter is filled with ink. A filler tube 12 for the container 11, combined with a non-return valve 13, is covered by a cap 31. Compressed air or carbon dioxide is introduced into the container above the ink so that the latter is forced out when the valve 22 is opened. The ink in the container may be heated by an electric unit which is thermostatically controlled. The ball of a ball-point pen may be removed from the reservoir prior to filling by means described in Specification 656,768.
