Title: Pressure surge sensor with piston magnet and rupture disc
Inventor: WIDDAS CHRISTOPHER JOHN
IPC: F16K37/00
Filed: 2009-10-19
Abstract: A pressure surge sensor has a body (10) having a cylinder passage (13), a magnetically actuated electrical switch (17) mounted on the body, and a piston member (20) movable along the passage relative to the switch. The piston member carries a magnet. When the cylinder passage (13) is coupled to a fluid pressure surge source, a fluid pressure surge applied causes the piston member to move along the cylinder passage relative to said switch, thereby actuating the switch. A breakable retainer element (26) restrains the piston member against movement, and the piston is freely movable along the cylinder passage, after release by the retainer. The pressure surge sensor is suitable to be arranged downstream of a rupture disc, which releases overpressure of a pressurized apparatus, for example an extrusion apparatus, or a gas handling or gas storage system.

Title: Improvements in devices for protecting furnaces at times of flame failure
Inventor: SAWYER WILFRID ALBERT
IPC: F23M11/00
Filed: 1953-04-13
Abstract: 730,619. Controlling burners. RHEOSTATIC CO., Ltd. April 13,1953, No. 10026/53. Class 75 (1). [Also in Group XL (b)] An electronic safety control device for the protection of furnaces burning fluid or pulverized fuel comprises a fuel valve which is manually opened and is held open, provided there is a flame in the furnace, by an electromagnetic coil 27 connected between two windings T3, T4 of a transformer each providing anode voltage for the final stage of the electronic device, one end of the coil being connected either directly or through a rectifier 28 to earth. In the circuit shown, a P.D. is built up on a resistance R3 on alternate half cycles of the voltage from the winding T4 and this P.D. charges a capacitor C1 if a flame exists at the burner 1 to connect electrically the burner and a probe 4. The capacitor is by-passed by a resistance R2 and the time constant of the combination is such that the capacitor retains a substantial fraction of its charge during the half cycles when no P.D. appears on the resistance R3 on account of the rectifier 28. The capacitor voltage provides negative grid bias for a thermionic valve V1, the anode circuit of which includes a winding T2 of the transformer and a resistance R4, the winding T2 being connected so that the anode is positive during the half cycles when the capacitor C1 is discharging through resistance R2. The P.D. built up on the resistance R4 by the anode current of valve V1 provides negative grid bias for a second thermionic valve V2, the anode circuit of which includes the winding T3 of the transformer, the electromagnetic coil 27 for holding the fuel valve open and the winding T4 of the transformer. The windings T3, T4 are connected so that their voltages are additive and so that the anode of valve V2 is positive on the same half cycle as the anode of VI. If the burner flame fails the capacitor does not charge and if a low-resistance fault develops between the probe 4 and the burner the charge on the capacitor leaks away rapidly. In consequence in both cases no negative bias is impressed on valve V1 during the half cycles when its anode is positive and a high negative bias is therefore built up on resistance R4 sufficient to cut off the anode current of valve V2 and de-energize the electromagnetic coil 27. In a modified circuit the rectifier 28 is replaced by a conductor and the rectifying action of the burner flame is utilized to charge the capacitor C1. The probe is surrounded by an earthed screen 7. A photo-cell may be used instead of a probe for detecting the burner flame. Specification 720,914 is referred to.

Abstract: 1389246 Extrusion coating wires LYNENWERK KG 3 March 1972 [28 Oct 1971] 10072/72 Heading B5A In an extruder crosshead die for applying plastics sheathing and reinforcing or strain relieving elements to conductors, two sheaths, e.g. of polythene are formed and reinforcing threads, e.g. glass filaments, are fed between the two sheaths via converging feed channels 24 symmetrically spaced within members 15, 16 and 17 forming a cone secured within the die body 2. Plastics material is fed by a screw extruder through passage 10 and is deflected into annular passage 26. Part of the plastic melt flows down conical passage 34 to form the outer sheath between a die 5 and member 15. The remainder is diverted through radial slots 29 passing between channels 24 carrying the reinforcing threads into converging passages 30 leading to an annular cavity 31. The melt passes from cavity 31 between member 15 and a nipple 22 to form the inner sheath directly on the conductor passing through passageway 1. The nipple 22 is attached to a tube 21 adjustably mounted in a tubular extension 18 of member 16. Between the members 16 and 17 the channels 24 carrying the reinforcing threads pass through an annular chamber 39, 40 to which vacuum is applied through passages 38 to prevent bubbles forming within the sheath. The die is heated by electrical heaters 12, 13 and 14 and the channels 24 may have heated rearward extensions. The channels 24 have ceramic entry bushes 25 and the holder 6 for die 5 is adjustable by centring screws 9.

Abstract: 399,554. Reproducing music. JONES, W. B., 38, South Dearborn Street, Chicago, U.S.A. April 8, 1932, No. 10102. [Class 40 (iv).] To produce a binaural effect, musical sounds are transmitted from a single source to a listener by two channels one of which delays the high frequencies and the other the low frequencies, the sounds emitted from 'the two channels being transmitted to reach the left and right ears respectively of a listener so that a directional effect is simulated. As shown in Fig. 1, sounds from a source 10 are communicated to a listener A over channels 11, 12 and ear pieces 15, 16. The channel 12 contains a network 14 which delays the lower frequencies whilst channel 11 contains a network 13 delaying the higher frequencies, the joint effect being that lower notes appear to come from the left, higher notes from the right and medium frequencies from intermediate positions. Fig. 4 shows an arrangement wherein two loudspeakers 28, 29 reproduce the sounds which are heard by a listener at 27. The loud-speakers 28, 29 may be designed to delay the high and low frequencies respectively in which case one or both the networks 13, 14 may be dispensed with.

Title: Improvements in or relating to reeds for textile purposes
Inventor: TAYLOR MATTHEW MICHAEL
IPC: D03D49/62
Filed: 1950-04-27
Abstract: 693,629. Reeds for looms; yarns. BRITISH CELANESE, Ltd. April 25, 1951 [April 27, 1950], No. 10402/50. Classes 120(iii) and 142(iii) The yarn 14, spacing the wires 13 of a reed and securing them in position by being wound round the baulk members 12, between which the wires extend, has a content of thermoplastic textile fibres and of other and relatively non-thermoplastic textile fibres such that the wires, baulk members and the yarn can be fixed relatively to one another by the coalescence of the thermoplastic fibres in the yarn. In one arrangement the yarn comprises fibres of cellulose acetate, preferably in the form of continuous filaments, combined with fibres of regenerated cellulose, the cellulose acetate fibres being softened by dipping the baulks in acetone to fix the wires, baulks and yarn to one another. and then allowed to dry. To assist the coalescence of the parts the baulks may be painted with an acetonesoluble paint. The baulk members may be constructed with reinforcing members and may be of cellulose acetate plastic material which is superficially softened when they are immersed in acetone to ensure a firm bond between the yarn and themselves. Alternatively the baulk members may be hollow or may have a split tube 36 which secures the wires by sliding over the baulk members and the ends of the wire with the jaws of the tube gripping beneath the baulk members. Instead of using continuous filaments of regenerated cellulose as the relatively non-thermoplastic basis of the yarn, cotton or linen fibres may be used, or even artificial fibres, and preferably continuous filaments, of high melting synthetic linear polymers such as.polyamides, which can be associated with thermoplastic filaments that can be softened without softening the high melting filaments. The yarn used for binding the dents may be made up of eight ends 16 of continuous filament cellulose acetate yarn and eight ends 17 of high tenacity regenerated cellulose yarn, two of the ends 16 being doubled with two of the ends 17 to form each of four doubled yarns 18 and the four yarns 18 being further doubled together in the reverse direction to produce the yarn 14. The proportions of ends 16 and 17 may be varied if desired. In an alternative method of making up the yarn, it may have as its basis a low twist, yarn 21 of continuous high tenacity regenerated cellulose filaments, this yarn 21 being covered with four ends 22 of multifilament cellulose acetate yarn lapped in one direction at twelve to fifteen laps per inch to form a covered yarn 24. The yarn 24 is further covered with four ends 25 of cellulose acetate continuous filament yarn lapped in the opposite direction to the yarns 22 so as to form the double covered yarn 26.
