Title: Control of yarn tensions
IPC: D04B15/48
Filed: 1973-09-11
Abstract: 1449492  1449492 Yarn tensioning K BOUS 11 Sept 1973 [19 Sept 1972] 42704/73 Heading D1D In a yarn tensioner yarn is wound around two spaced rolling elements, and an adjustably loaded braking pin, movably arranged between the elements, abuts the windings, the engagement between the braking pin and yarn being such that the angle over which the yarn contacts the pin decreases to counteract increasing yarn tension and increases to counteract decreasing yarn tension to maintain contact yarn tension. As shown in Fig. 1, yarn runs about rollers 2, 3 and interchangeable yarn-engaging pin 7 is moved between optical fixed yarnengaging pins 15, 16 by levers 8, 9 bearing movable weights. Rollers 3 may be fixed on pin 4, or may be replaced by a smooth or multi-grooved roller. The distance between the yarn windings may be adjusted by inclining the guide pin or rollers. The pin 7 may be biased by tension or compression springs, by movable permanent magnets or by centrally adjustable electromagnets. If tension becomes very high or low, the movement of pin 7 causes the temporary stopping of yarn withdrawal. As shown in Fig. 2, pin 23 is pivoted by tension sensing arm 21 and biased by a spring 25 which may be replaced by weights, magnets or centrally adjustable electromagnets. The yarn tension or yarn speed device of an associated machine may act on lever 20 or the spring via rods, or by using electrical, electromagnetic, pneumatic or hydraulic means. As shown in Fig. 3 yarn is looped around driven rollers 27, 28, and lever 22 pivots about spindle 31 to urge yarn-engaging pin 33 between fixed yarn-engaging members 29, 30. Lever 32 is pivoted by lever 38 with varying yarn tension, is biased by spring 34, and is damped by permanent magnet 41 and pivotable segment 40. As shown in Fig. 5, yarn loops about rollers 68, 69 and lever 60 pivots with varying yarn tension to pivot both 61 bearing movable weight 62 and lever 63 bearing yarn-engaging pin 64. Levers 72, 73, 75 form a similar tensioning system. The levers may be counterbalanced by springs or permanent magnets.

Title: Improvements in or relating to shears
IPC: B23D25/12
Filed: 1959-12-16
Abstract: 876,768. Shearing. UNITED ENGINEERING & FOUNDRY CO. Dec. 16, 1959, No. 42767/59. Class 83 (4). In a flying shear for cutting strip materials in which the blades are on rotatable carriers 41, 47, the speed of the blades fluctuates during each revolution, and the carriers are adjustable so that the blades may cut at the maximum or minimum speeds attained during a revolution, longer strips being produced by cuts at the maximum speed than at the minimum speed for a given size of carrier. The average speed of the carriers is also adjustable to extend the range of strip-lengths, the blades travelling faster or slower than the strip at the instant of cut. Feedrolls 12 for the strip S and the carriers 41, 47 are driven by a motor 13, driving through a reduction gear 14 and a gear-box 16. The drive from the gear-box to the feed-rolls is by a shaft 21 and to the carriers 41, 47 by an infinitely-variable drive unit 24 which drives a change-speed gear-box 25 connected through gears 27, 28, 31, 32 to a drive shaft 33 for the carriers. The shaft 33 is eccentric to a shaft 38 which it drives through a crank connection comprising a crank and a pin 36, 37 on shaft 38 connected to a radial slide on a crank 34 of shaft 33. Thus the angular speed of shaft 38 fluctuates from a maximum when the effective radius of crank 34 is increased by the eccentricity e, as shown in Fig. 6, to a minimum at 180 degrees from this position. A coupling 42 between shaft 38 and the shaft 39 supporting the blade-carrier 41 may be moved by a pivoted yoke 43 to the disengaged position, Fig. 2, to permit rotation through 180 degrees of shaft 39 in relation to shaft 38, so that the blades may cut at the fast or slow parts of their rotary cycle. An operating rod 45 for yoke 43 co-operates with a catch 40 and is moved by a handle 46a on a frame 46 on the rod. A rotatable key 49 for engaging a square socket in the end of the carrier-shaft 39 is carried by the frame 46, and is withdrawn from the socket when the frame is moved to the left (Fig. 2) to engage coupling 42. The setting of the coupling is indicated by a pointer 52 on a shaft 53 geared at 54, 55 to shaft 38, and pointers 60, 61 on a sleeve 56 mounted on shaft 53 and geared at 57, 58 to carrier 41. A stock-guide 63, Fig. 5, is located between the feed-rolls 12 and the blade-carriers, and a rubber &c. stripper 64 behind the cutting blade strips the end of the stock from the blade.

Title: Improvements in or relating to fuel elements for nuclear reactors
Inventor: WILLIAMS DAVID WILLIAM
IPC: G21C17/10
Filed: 1959-12-29
Abstract: 900,348. Nuclear fuel elements. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Dec. 5, 1960 [Dec. 29, 1959], No. 44162/59. Class 39 (4). In order to detect ingress of coolant through a fault in a sheath of a nuclear fuel element, the element includes a substance which, at a temperature above the normal operating temperature, expands more rapidly than the fuel member and sheath so as to distort the sheath. Should oxidation of the fuel member occur due to ingress of coolant, the oxidation products will inhibit heat transfer and the temperature of the fuel member will rise, the resultant distortion of the sheath being detected either by means of a strain indicator or by breaching of the sheath to release fission products which may be detected by conventional monitoring of the coolant. In one example, a uranium fuel member 1 in a sheath 2 to which are welded end caps 3 has a channel 5, into which is inserted an aluminium strip 6 in a niobium sheath 7 having a pierce 8 immediately below a weakened zone 4 in the upper end cap 3. Should ingress of the carbon dioxide coolant occur, for example through a faulty weld between the sheath 2 and an end cap 3, the temperature will rise due to oxide building up on the fuel member 1 and the aluminium strip 6 melt, pushing the pierce 8 through the weakened zone 4. In further examples, the substance comprises uranium iodide which can be vaporized by sublimation and so distort the sheath by its vapour pressure, and uranium treated so as to expand anisotropically and arranged to distort the sheath by expansion in the preferred direction. Specification 900,347 is referred to.

Title: Communication system
IPC: H04N1/36
Filed: 1965-10-19
Abstract: 1,125,959. Copying by scanning. XEROX CORP. 19 Oct., 1965 [26 Oct., 1964], No. 44235/65. Heading H4F. [Also in Division H2] A communication system for transmitting to remotely located receiver signals including synchronizing signals, e.g. facsimile signals, comprises a receiver adapted to generate a twolevel condition signal, continuously indicative of the state of synchronization of the receiver with respect to the transmitter, and reverse transmission means to transmit the condition signal from the receiver to the transmitter. The condition signal indicating achieved synchronism may be indicated at the transmitting location by a lamp or it may be connected to a transmitter control unit and used to prevent transmission of actual information bearing signals until synchronism has been achieved and to interrupt such transmission if synchronism is lost. The combined video and synchronizing signals on input line 20 of the receiver, Fig. 2, are fed to a facsimile recorder 16 and to a synchronizing signal separator 22 via a gate 21. These synchronizing signals are then fed to a phase comparator 23 where they are compared with signals generated by a local synchronization generator 25 to produce an error correction signal which is fed via control unit 24 to phase look the oscillator 25 to the incoming signal; unit 26 comprises a shaping and delay circuit which provides a variety of pulse outputs with various delays and widths synchronized with the local synchronization signal. The two synchronizing signals are also fed to a coincidence detector 27 which generates an in-synchronization signal on line 29 when the two signals are in synchronization for a predetermined number of synchronization periods. This signal is connected by a supervisory channel back to the transmitting apparatus, and is also applied to close input gate 21 to disconnect the received signal from the separator 22 except during the time intervals when the synchronizing signals appear. During times when the two synchronizing signals go out of synchronization for more than a predetermined number of synchronization periods the gate 21 remains permanently open. The recorder 16 is synchronized by the outputs D and E of unit 26. The subject-matter of this Specification is identical with that of Specifications 1,125,957 and 1,125,958, the claims of which relate to the circuit arrangements as described with reference to Figs. 3A, 3B and 3C (not shown).

Patent GB-445078-A (GB)
Abstract: 445,078. Distant - control systems. LANDIS & GYR AKT.-GES., 1, Hofstrasse, Zug, Switzerland. July 23, 1935, No. 20914. Convention date, Aug. 17, 1934. [Class 40 (i)] In a system for selectively controlling resonance apparatus more particularly over power mains, the transmitter frequencies are derived from an A.C. generator run at variable speed and are switched on to the mains when the speed reaches a value predetermined by apparatus, the speed of which is controlled in accordance with the frequency to be transmitted. The generator 2 for supplying control frequencies to the power mains 5 is driven by a shunt motor 1, the speed of which is controlled by a rheostat 13 driven by a reversible motor 11 through an electromagnetic clutch 16. The motor 1 also drives an auxiliary generator 3 which supplies a synchronous motor 9 driving one sun-wheel 7 of a differential gear. The second sun-wheel 25 may be driven at different speeds through ratchet gearing by synchronous motors 20, 20<1>, 20<11> which are under the control of switches 21, 21<1>, 2111. The planet-wheel 32 of the differential gear actuates a contact arm 38 which controls the motor 11. When it is desired to transmit a particular frequency, one of the switches 21, 21<1>, 21<11> and switch 37 are closed and the sun-wheel 25 is rotated at the corresponding speed. Motor 11 controlled by arm 38 also adjusts the rheostat 13 to increase the speed of generator 2 and also that of motor 9 and sun-wheel 7 until when the speed of the wheel 7 exceeds that of 25, movement of the planet-wheel 32 is reversed to throw over the arm 38 into engagement with contact 41 to reverse the direction of rotation of motor 11. During the throw over contact 27 is operated to energize the electromagnet 30 which locks up and operates the switch 4 for connecting the generator 2 to the power network 5. Reversal of the motor 11 brings about a decrease in speed of the generator 2 and consequently the planet-wheel 9 until when it falls below the speed of 25 the arm 38 is again thrown over to reverse the operation. In this manner a narrow band of frequencies corresponding to the switch 21, 21<1> or 21<11> is superposed on the network 5. Instead of utilizing a number of synchronous motors 20, 20<1>, 20<11>, a single motor provided with a plurality of gears of different ratio may be employed. Moreover, the motors may be supplied by a thermionic generator.
