Title: Spinnerets for artificial filament manufacture
IPC: D01D4/02
Filed: 1961-11-22
Abstract: 1,006,830. Spinnerets. CELANESE CORPORATION OF AMERICA. Nov. 22, 1961 [Dec. 1, 1960], No. 41758/61. Heading B5B. A spinneret has one or more orifices each having its axis normal to the spinneret face and having, in axial cross section, a rectilinear portion, the walls of which run from the outlet face of the spinneret parallel to its axis and join another section having walls diverging toward the inlet face of the spinneret, the meeting angle of the diverging walls being less than 60 degrees for a distance from the inner end of the rectlinear portion of the orifice at least equal to 0À5 times the width of said portion and thereafter being at least 20 degrees larger for a distance of from 50 to 90% of the thickness of the spinneret face. The rectilinear portion is preferably cylindrical, but may alternatively be of square or triangular cross-section. A preferred form (Fig. 5), has two successive frusto-conical portions 15, 14 of which are joins, the inner end of the cylindrical portion 16 the widest part of the frusto-conical portions being towards the inlet face. In this case the meeting angle of each frusto-conical portion of the orifice is the angle which would be formed by continuing the walls of each frusto-conical portion until they meet. The diverging walls may also be hyperbolic in form (Fig. 6). In these cases the meeting angle at a given distance from the inner end of the rectilinear portion of the orifice is defined as the angle α formed by continuing tangents to the curved diverging walls, at points spaced the same distance from the inner end A of the rectilinear portion, until they meet. Preferably the meeting angle is 35 degrees or less, for a distance from the inner end of the rectilinear portion of the orifice to at least as far as a point spaced therefrom by a distance equal to the width of said rectilinear portion. Thus, as in Fig. 5, the inner end of the cylindrical portion 16 joins a frusto-conical portion 15 having a meeting angle of 35 degrees or less and the portion 15 joins a further frusto-conical portion 14 the meeting angle of which is from 50-60 degrees. The outlet face of the spinneret may be less than 1000 microns thick and the rectilinear portion of each orifice may have an area of less than 0À02 sq. mm. and a length of from 0À5-1À5 times its width. Such spinnerets are useful in the dry-spinning of cellulose triacetate from solvents consisting wholly or mainly of methylene chloride.

Title: Improvements in or relating to anemometers
IPC: G01P5/07
Filed: 1963-10-25
Abstract: 982,511. Anemometers. COMMONWEALTH OF AUSTRALIA. Oct. 25, 1963 [Oct. 26, 1962], No. 42256/63. Heading G1R. In an anemometer the wind speed is measured by cups 16 rotating a disc 22 which, at each revolution moves a slug 23of high permeability material through an air gap 24 in a permanent magnet 25 to produce a pulse in a coil 26 and these pulses are fed to a single stage amplifier and actuate a Schmitt trigger circuit to generate pulses of a square wave form. The square wave form pulses are fed to a nine-stage binary counter each state of which is an identical circuit, Fig. 7 (not shown). A pulse is then fed from the nine-stage counter to the first stage of a four stage binary counter similar to the nine-stage binary counter and as a result a sequence circuit will actuate punches to punch a binary code in a tape representing wind speed. The wind direction is measured by a vane 28 rotating a magnet 36 by a magnet 35 carried by a shaft 31. The magnet 36 is connected, through gears, to a shaft of a selsyn transmitter 38 and through 6:1 reduction gearing to a second selsyn transmitter 39. A "disc-in-oil" damping device is also driven by the magnet 36. Each selsyn 38, 39 has three secondary windings and single common primary windings and the arrangement is such that the direction of rotation of the vane 28 can be measured to 10 degrees. The voltage comparison circuit for determining which of the windings carry positive or negative voltage is described with reference to Fig. 9 (not shown) and the sequence of operation is such that a gate transistor is prepared by each negative winding for the sequence circuit to connect it to its punch. The power supply is a conventional phase shift oscillator with push-pull output and is controlled by switching transistors so that the power supply is on for approximately 1 second in each 10 minutes. A check digit, controlled by a photo-electric relay Fig. 10 (not shown), is a character punched in the tape to provide separation between the readings to indicate whether the readings were taken in daylight or darkness. The sequence circuit is energized each 10 minutes by a time switch. The tape punch unit is developed from a standard teletype perforation unit. As a precaution against accepting false readings a computer is designed to reject all readings which do not have an odd number of holes in the digits punched. Manual controls consisting of an auto/off/manual rotary switch and auto test, erase, stop, start and tape feed buttons are provided.

Abstract: 1292360 Valves ATLAS COPCO AB 10 Sept 1970 [19 Sept 1969] 43261/70 Heading F2V [Also in Division G3] In the fluid control device of Fig. 1, application of a pressure pulse to inlet 16 results in a delayed outlet pulse being generated in outlet 17, the delay being due to the provision of a throttle 1 and a cavity 3 in the path 12, 4, 3, 14 between the inlet and outlet. Venting of the cavity 3 is inhibited as long as the inlet pulse exists on account of a diaphragm 9 which flexes under the influence of the pulse supplied through passage 11 to so close off a passage 5 extending from the cavity 3 and leading to an atmospheric vent 6. In the modified form of device as shown in Fig. 2, the inlet pulse enters each of passages 11, 12 and 13 and so causes an upward flexing of diaphragm 7, a flow into cavity 3 past throttle 1, and a flow to the underside of a downwardly biased diaphragm 23. Initially, the input pulse is sufficient to lift the diaphragm valve 20 and so an output pulse is generated simultaneously with the application of an input pulse. Subsequently, when the cavity pressure has increased sufficiently, diaphragm valve 20 closes. Thereafter, outlet 17 vents through passage 8 whilst cavity 3 vents through passages 5, 6 immediately the input pulse is reduced.

Title: Anti-skid methods and systems
IPC: B60T8/50
Filed: 1970-09-14
Abstract: 1319968 Anti-skid systems; compressed air systems WESTINGHOUSE BREMSEN-UND APPARATEBAU GmbH 14 Sept 1970 [15 Sept 1969] 43753/70 Heading F2F An anti-skid compressed air braking system for a vehicle comprises a detector 1 which measures either the deceleration or the slip of a vehicle wheel as an indication of a skidding threshold and upon the attainment of a critical value thereof closes an energizing circuit 2 to actuate an electromagnetic valve 3; this causes the pressure of the compressed air acting at a brake cylinder 25 to be relieved and after a lapse of time to be increased again but the pressure prevailing at the time that the brake pressure is relieved is stored and controls the subsequent increase in braking pressure so that the increase in braking pressure is reduced by a quantity dependent on the amount of braking-pressure which caused the attainment of the critical value, such that the aforesaid quantity is less at a higher amount of braking pressure than at a lower amount of braking pressure. In the embodiment shown in Fig. 1, the system includes a housing 4 containing a valve system 5 and a piston assembly 6 and these components take up their initial position as illustrated. To initiate braking a valve 22 is actuated and air from a container 9 flows via a brake line 21 into chambers 10, 11 and via a duct 36 into a chamber 32 and via a valve 37 into a chamber 31, whereby the piston assembly 6 is displaced to the left: air flows from chamber 11 via duct 23 to the front side of cylinder 25 which is double acting. Upon the skidding threshold being sensed, line 8 is pressurized and a piston slide 7 of the valve system 5 is moved to the right: as a result a passage between chambers 10 and 11 is closed, a passage between chambers 11 and 12 is opened and a passage between chamber 12 and a vented chamber 13 is closed. Compressed air at the front side of cylinder 25 and in chamber 32 pass via chamber 12 and a line 24 to the rear side of brake cylinder 25 to relieve the braking, and also via a duct 34 to a chamber 33 and to a chamber 30 by slow leakage through a valve 35. The piston assembly 6 is thereby moved to the left until piston rod 28 moves the piston slide 7 whereby chamber 11 is cut off from chamber 12, chamber 10 is cut off from chamber 11 and chamber 12 is cut off from chamber 13. On the vehicle wheel accelerating the line 8 is vented, and the piston slide 7 returns to its initial position. In the embodiment of Fig. 3 a detector 101 is operable on an electromagnetic valve system 105, and a housing 104 contains a piston assembly 106 incorporating a pressure reducing valve 118: a single acting brake cylinder 142 is connected to a chamber 131 via a non-return valve 137 incorporating a throttle. When a skid threshold is sensed the valve system 105 is changed over and the supply of compressed air to the single acting brake cylinder 142 is cut off. The air can pass through lines 136, 134 now connected and via open valve 118 to atmosphere until the forces acting on the piston assembly 106 attain equilibrium and close valve 118.
