Title: A flyer for a roving machine
IPC: D01H7/32
Filed: 1965-08-26
Abstract: In a speed-frame flyer, to minimise the variation in the effect of the counterweight on the presser-foot as the package grows, the counterweight is arranged at such an angle relatively to the foot that the "leverage distance" of the centrifugal force acting at the centre of gravity of the counterweight, and the distance of the centre of gravity of the foot from the axis of rotation of the flyer increase in the same ratio.  The "leverage distance" at any instant is defined as the distance from the pivot of the foot to the centre of gravity of the counterweight when projected on the tangent at the pivot to the circle of rotation of the pivot. In a preferred arrangement, as the foot pivots outwardly, the angle between the tangent and the line joining the pivot and the centre of gravity of the counterweight decreases from 60 degrees to 18 degrees.  In the forms described, the counterweight is disposed within the flyer arm, the cross-section of which is of streamlined form.  In Fig. 3, (not shown), the counterweight is of lead and the arm and foot of aluminium: the counterweight and foot are cast together and mounted on pins rotatably received in upper and lower bores in the arm.  The roving is conducted through a steel-lined bore with a threading-slot. In Fig. 5, (not shown), the counterweight and foot are attached to a tube through which the roving is conducted, a threading-slot in the tube registering with a slot in the arm when the foot is pivoted away from the spool.

Abstract: 811,451. Multiplex radio signalling. GENERAL ELECTRIC CO. Ltd. Dec. 11, 1956 [Dec. 23, 1955], No. 36971/55. Class 40 (5). In a double superheterodyne receiver for multiplex amplitude-modulated signals the second local oscillator is controlled by, and made equal in frequency to, one of the signals.

Title: Beam current limiting arrangement
IPC: H04N5/14
Filed: 1969-07-23
Abstract: 1,269,388. Cathode-ray tube circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 23 July, 1969 [31 July, 1968], No. 36987/69. Heading H4T.  The beam current of a colour television cathode-ray tube is limited by deriving a D.C. signal when the beam current exceeds a predetermined value and supplying this D.C. signal to the tube via the video amplifier with the polarity appropriate to reducing the beam current. Thus, as shown in Fig. 1, a D.C. voltage produced across resistor 22 connected in series with the H.V. winding 20 of the line transformer renders a transistor 26 non- conducting when the voltage exceeds a value indicative of a normal beam current. Transistor 31 then becomes conductive and the D.C. voltage of its collector is then applied to the input of stage 5 of the video amplifier where it is added to the D.C. voltage produced by the D.C. restoration circuit consisting of the elements 11 to 17, the polarity being such that the output voltage from stage 8 which is supplied to one of the guns of the tube 18 ensures that the normal beam current is not exceeded. The onset of beam-current limitation may be adjusted by a D.C. voltage applied to terminal 28. In a second embodiment (Fig. 2), D.C. restoration is effected by means of a keyed rectification circuit comprising diode 11a and the elements 15, 16, 17, 45, 46, and 51 line flyback pulses being applied at terminal 52. When the beam current exceeds the normal value the collector current of transistor 37 is reduced, the cathode potential of diode 44 increases and the amplitude of the keying pulses (line fly-back pulses) increases to the same extent so that the D.C. voltage in the video amplifier increases thus limiting the beam current. The elements 48 and 50 are connected to respective video amplifiers associated with the other guns of tube 18.

Title: Directional gyroscope
IPC: G01C25/00
Filed: 1963-09-23
Abstract: 997,469. Gyroscopes. BENDIX CORPORATION. Sept 23, 1963 [Sept. 28, 1962], No. 37385/63. Heading G1C. A directional gyroscope comprising a rotor 29 mounted with three degrees of freedom in an outer gimbal 25 pivotal about an axis C - C and an inner gimbal 27 pivotal about a perpendicular axis D - D and including means 33, 31 for applying torques about the respective axes has a timing device which assigns predetermined periods to the adjustment operations about each axis and to the normal operation of the gyroscope. The vertical gimbal 25 carries two syncros 35, 37 the first sensing movement of the gimbal 27 about the axis D - D and the second being operated by a pendulum 39, and the output of these syncros is fed through a conductor 65 to an amplifier 67 and to the input of a syncro 73 in an integrating mechanism 76. The integrating mechanism applies a signal to an input 83 of an amplifier 85, and comprises a motor 78 driving a rate generator 81 and the syncro 73 through gearing 79. The timing device includes a pair of commutators 52, 54 having rotatable switch arms 55, 57 driven by a constant speed electric motor 61 at a suitable rate such as one revolution in ten minutes. In the position shown the output of amplifier 67 is connected via contacts 52A, 53A to torquer 33 so that a signal proportional to the angle that the gyro axis E - E makes with the horizontal is fed to the control winding of torquer 33 which applies a torque about the axis C - C to cause a precession about the axis D - D tending to level the gyro. At the same time the output of amplifier 85 is connected via contacts 54A, 56A to the control winding of motor 78 so that syncro 73 is driven to a null with respect to the actual gyro position. Normal directional operation of the gyro is initiated by the switch arms 55, 57 leaving the "A" contacts, and after some time has elapsed the switch arms reach the "B" contacts. In this position the output from amplifier 85, representing an angle error between syncros 35 and 37 and syncro 73, is fed via contacts 52B, 53B to the control winding of torquer 31 which applies a torque about the axis D - D to cause a precession about the axis C - C. At the same time the output of amplifier 85 is again connected via the commutator 54 to the control winding of motor 78, so that whilst the syncro 73 is being driven to a null the gyro will be given an incremental correction in azimuth. Further incremental corrections, which alternate with periods of normal directional operation, take place when the switch arms reach the "C", "D" and "E" contacts.

Title: Method and apparatus for continuously casting metal
IPC: B22D11/04
Filed: 1954-12-24
Abstract: 805,465. Continuous-casting machines. TARQUINEE, V., and SCOVILL, J. Dec. 24, 1954, No. 37427/54. Class 83 (1). A continuous-casting method comprises initially forming a peripheral skin of solidified metal by applying fluid coolant continuously to the exterior of the mould, progressively thickening the skin by applying a fluid coolant directly to the skin while in the mould while gradually decreasing the radial support afforded the skin, and maintaining the application of coolant after the metal, still molten except for the outer shell, has left the mould, until the peripheral skin has built up sufficient thickness to absorb the heat from the molten core and to solidify the core without deformation. The melt is poured into a basket 24, Figs. 1 and 2, to which the mould 51 is connected, and the outgoing ingot 29 passes through support rolls 30, 31, a soaking furnace 32, reduction rolls 34-37 and thence to flying shears 38. The pouring basket 24 comprises a pear-shaped recess 44 and a graphite sleeve 50 aligned with the thin copper mould 51. High-pressure fluid coolant jets 68 are directed to the exterior of the mould from annular cooling heads 59-62, baffles 70 being interposed between the heads. The peripheral skin 58 formed thereby is then progressively exposed to the direct application of the coolant through perforations 172 in the mould wall, Fig. 10, which are circumferentially spaced and axially staggered, and increase in size in the downstream direction. To improve the cooling, the skin is maintained in firm contact with the mould wall by maintaining a predetermined head H of molten metal above the mould. The end of the mould is formed with a series of prongs 76, between which the coolant impinges on the thickening skin 58. The ingot is subjected to further cooling, after leaving the mould, by spray-heads 78. By proper regulation of the heat content of the ingot prior to its entry into the soaking-furnace 32, it may be brought to a rolling temperature with the addition of little or no outside heat. In modifications, the mould has a number of helical slots 80, Fig. 11, or axially spaced transverse slots, or is of cage-like form, being defined by bars 90-92, Fig. 13, of varying lengths supported by hoops 94-96.

Metal such as steel or steel alloy is continuously cast in a copper mould 2 which has coolant water passages 4 and the strand is subsequently cooled directly by flat jets 13 of coolant water delivered with a high kinetic energy per unit area, e.g. 20 Kp.m. per sq. em., of the strand surface, between flat steel guidestiips 8 of a cooling cage 3 which contacts the strand, the breadth of the coolant jets being less than that of gaps between the guide-strips. The water is supplied to flat-jet nozzles 12 from an annular conduit 11, but, instead of one such nozzle to each gap as shown, there may be several flat- or round-jet nozzles down the length of the gap to produce a combined flat jet at the strand surface. The density and/or energy of the jet may decrease towards the bottom of the cooling area. The cooling cage 3 of guide-strips 8 may be detachably secured to the mould 1 and may be the same length as the latter, whose length may be twice the width of the strand or less. A casting speed of 2À8 m./min. with a strand shell temperature below the cage of under 1000 C. is said to be achievable.

Abstract: 1476671 Boring earth, wells &c DRILLING SYSTEMS INTERNATIONAL INC 28 Aug 1974 [17 Oct 1973] 37628/74 Heading E1F A motion compensating device, e.g. for supporting a load from a floating vessel, includes a multiple piston and cylinder arrangement having a primary chamber which is passively supplied with fluid acting to support the load and a secondary chamber actively supplied with fluid which acts in the opposite direction, the secondary chamber being formed in the piston rod of the primary chamber. In a first embodiment (Figs. 1, 2) the motion compensating device 22 is interposed between the travelling block 27 of a derrick 24 carried by a floating vessel 13 and the hook 21 supporting the load, e.g. drill string 14 or a blowout preventor (not shown) to be landed on the well head 17. The motion compensating device 22 consists of a pair of piston and cylinder arrangements 39 and 39' as shown, or a single piston and cylinder arrangement (Fig. 6, not shown). The piston and cylinder arrangement 39 includes an outer cylinder 43, an inner cylinder 46 and a piston 47 having a hollow piston rod 41 which slides over the inner cylinder 46 to define a primary chamber 51 and a secondary chamber 52. The primary chamber 51 is passively supplied with fluid by means of an oil/air interface tank 35 and a bank of air accumulator tanks 36, the fluid in chamber 51 acting to support the load on the hook 21. The secondary chamber 52 is actively supplied with fluid by a system 37, the fluid in chamber 52 acting in the opposite direction to the fluid in the chamber 51. A first active fluid supply system 37 (Fig. 2) includes a bidirectional, variable volume pump 61 controlled by signals from a control means 65. The control means 65 may operate in a constant position mode, e.g. when landing a blowout preventor, or in a constant pressure mode, e.g. to maintain a constant weight on the drill bit 15. When operating in a constant position mode the control means 65 responds to signals from position transducer 80 which measures the position of the vessel 13 relative to the sea bed 12 and to position transducer 75 which measures the position of the hook 21 relative to travelling block 27. The control means 65 may also respond additionally to corresponding velocity transducers 81 and 78. When operating in a constant pressure mode the control means 65 responds to pressure transducers 57 and 60 which respectively measure the pressures in primary chamber 51 and secondary chamber 52. An alternative active fluid supply system 37 (Fig. 5) includes a compensating cylinder 116 fixed to the vessel 13 and a piston 118 whose piston rod 120 is attached to a cable anchored to the sea bed 12. As the vessel experiences wave motion fluid will be forced into or out of the secondary chamber 52.
