Title: Improvements in or relating to the production of bulky yarn
Inventor: POOL WILLIAM
IPC: D02G1/16
Filed: 1954-10-20
Abstract: 793,044. Spinning and finishing yarns; thread guides; roller arrangements in textile spinning &c. machines. BRITISH CELANESE, Ltd. Oct. 18, 1955 [Oct. 20, 1954], No. 30213/54. Classes 120(2) and 120(3) An apparatus for producing bulky (and looped) yarn from a continuous filament yarn, as by the process of Specification 790,911, comprises an inlet tube extending through a chamber and provided with a jet tip which faces and enters the mouth of a venturi passage i.e. a passage beginning as a cone with a vertical angle of less than 60 degrees, converging steadily to a throat and then slowly enlarging, and co-operating therewith to form an annular passage for a fluid stream blown under pressure into the chamber and out through the venturi passage. The unit 7, Figs. 1 and 2, comprises a tube 8 having an enlarged yarn entrance 13 and threaded at 14 and 15 to be engaged by a spring-loaded head 17 and a collar 21 and jet tip 9, the tube slidably entering a tubular body 10, which is embraced by a union 11 for connecting to a compressed air line, and carries an extractor end piece 12 in which is formed a passage having a conical entrance 35 leading to a throat 36 and reopening to an oulet 37 and which co-operates with two conical portions on the tip viz. 38 and 41, to form an annular passage with a throat 42. The number of loops and curls in the bulked yarn may be increased by use of a cap 56, Fig. 5, which is removably attached to the extractor 12 by bayonet-fitting pins 57 and slots 58 and has an outlet 59 which is of smaller diameter than, and offset relatively to the axis of, the outlet 37. In the application shown in Fig. 3, untwisted yarn 43 is passed around a large diameter portion 44 of roller (being held in contact therewith by a loaded roller 47), upwardly through the jet unit 7, is drawn back to the nip between a small diameter portion 45 of the roller and a cork roller 46, passes through a guide 48, and is taken up on a ring spindle 49; the difference in diameter of the portions 44 and 45 compensates for the contraction of the yarn the loops in which are secured by the inserted twist. As shown in Fig. 4, a twisted or untwisted yarn 51, drawn from, or drawn from and twisted by, a stationary or rotating package 52, is forwarded by feed rollers 53 and passed through the jet unit 7 and a tension device 54 and is taken up on a drumdriven winding spindle 55 which operates at such speed in relation to the speed of rollers 53 as to allow for yarn contraction. Reference has been directed by the Comptroller to Specification 732,929.

Title: Improvements relating to the construction of bimetallic articles
Inventor: JR CHARLES EDWARD STEVENS
IPC: F16C33/14
Filed: 1950-12-11
Abstract: 686,809. Making composite articles. FAIRCHILD ENGINE & AIRPLANE CORPORATION. Dec. 11, 1950, No. 30264/50. Class 83 (ii). [Also in Group XXXIV] In a method of making a composite metal article comprising a ferrous part bonded to an aluminium base alloy part by means of an alloy composed predominantly of the two metals and having opposite thermal stress conditions in the two parts at ordinary temperatures, the thickness of the aluminium alloy part is so chosen that such stress conditions are maintained at high temperatures instead of becoming reversed. The invention is described as applied to making a brake drum having an inner steel drum 10 bonded to an outer heat conducting and dissipating member 11 of aluminium base alloy by a bonding film 12 of ferro-aluminium. When fully cooled from the bonding operation, the outer member 11 will be in tension and the inner member 10 and film 12 in compression as a result of the different coefficients of expansion of the materials. These stresses tend to become reversed and so weaken the bond if the temperature rises, as it may do in use, to between 600‹ and 1100‹ F. For an outer aluminium alloy layer of a thickness exceeding about one inch, the temperature at which the stress reversal occurs is approximately constant and then increases rapidly with decreasing thickness of the layer. The thickness of the layer required in order to avoid stress reversal at a given maximum working temperature may be calculated. The invention may be applied to articles such as pistons, cylinders, bearings and vacuum tube casings. A heatconducting layer may similarly be applied to the sides of a gear-wheel or to the side and flat bottom of a cooking utensil.

Title: Gaseous controlled fluidic throttling valve
IPC: F16K13/00
Filed: 1970-06-24
Abstract: 1318634 Rocket engines - fuel supply; regulating IC engine fuel supply BENDIX CORP 24 June 1970 [27 June 1969] 30760/70 Headings F1B and F1J [Also in Division G3] A rocket engine 18 is supplied with fuel and oxygen via two separate lines 14 and 16, respectively, each of which lines contains an identical flow-controlling valve 13. Valve 13 comprises a portion of the flow duct which is shaped as a venturi 20 and an annular chamber which surrounds the venturi and is in communication with the throat thereof by way of a radially extending opening 26. Inert gas, e.g. nitrogen, which has a density lower than that of the controlled fluid, is supplied to the annular chamber. It enters the venturi and so interacts with the fluid flowing therethrough, such interaction serving to control the amount of actual fuel or oxygen being fed to the engine. Fig.4 (not shown) depicts a modified form of the venturi valve. The quantity of fuel flowing to the combustion chamber 40 of a piston engine 38, is controlled by means of a fluidic venturi valve 12 located in the fuel flow line 50, and a pulse generating apparatus 52 the output of which is connected to the valve. A venturi-defining constriction in the fuel line 50 is surrounded by an annular chamber, (112) Fig. 2 (not shown), to which the output from generating apparatus 52 is connected by way of line 60, the output being in the form of a gas which when supplied to the annular chamber enters the flow line at the throat of the venturi and so by interacting with the fuel flow controls such flow. The density of the gas is lower than that of the controlled fuel. The pulse control apparatus includes a logic 54 which provides a control output signal, a source 62 which provides a cyclic signal determined by engine speed, a signal shaper 64 and a solenoid valve 56, the solenoid valve controlling the outflow from a source S which source contains inert gas.

Abstract: 648,590. Automatic frequency control systems. GENERAL ELECTRIC CO., Ltd., and FOOT, J. B. L. Nov. 30, 1948, No. 31054. [Class 38 (iv)] [Also in Group XL (b)] A high-frequency oscillator, of the kind in which frequency is determined by a resonant cavity, has its frequency adjusted by a non- linear resistive element placed within, or coupled to, the cavity, a control current being passed through the element to vary its resistance. As shown in Fig. 2, the resonant cavity comprises an outer cylinder 2 and an intermediate cylinder 3 connected respectively to the anode S and grid 9 of the triode valve 1. A further innermost cylinder 4 is connected to the cathode 7. The resistive element in the form of a filament lamp 23 is connected by a coaxial line 22, about one-eighth of a wavelength long, to a capacity pick-up within the cavity 2, 3. Control current is supplied through a valve 16, to the grid of which a control voltage is supplied. This voltage may be derived from a remote point, or from a frequency discriminator 21 tuned to the frequency desired for the oscillator and fed by a coaxial line 20 from the cavity 2, 3, the whole thus constituting an automatic frequency control. In a further arrangement, the coaxial line 22 is short-circuited at its outer end, and has its inner end inductively coupled to the cavity, the resistive element being connected in series with the inner conductor near its short-circuited end. The time constant of the resistive element 23 should be long enough to avoid response to current alternations, if A.C. is employed as control current, and to avoid response at audio-frequency if the oscillator is frequencymodulated. In a modified circuit (Fig. 1, not shown), the coiled lamp filament lies within the resonant cavity 2, 3 and is shunted by an external condenser which may be variable.
