Patent GB-942391-A (GB)
Title: Aircraft flight path control system
IPC: G05D1/02
Filed: 1960-02-12
Abstract: 942,391. Automatic control of aircraft. SPERRY RAND CORPORATION. Feb. 12, 1960 [March 2, 1959], No. 5020/60. Heading G3R. An aircraft is automatically steered along a radio-defined course by banking in dependence on signals from a radio receiver dependent on lateral displacement from course and signals dependent on short period deviation from a long period average heading derived from the actual heading of the aircraft. In Fig. 2 D.C. signals from a radio receiver 10 representative of the magnitude and sense of displacement of an aircraft from a localizer radio beam are converted to A.C. signals in a unit 11 producing outputs, representative of displacement and rate of displacement, which are added together in a unit 12 controlling the ailerons through a velocity-type servo-system 26 to which signals from the roll pick-off of a gyro-vertical 23 and roll angular accelerometers 25 are applied. During the initial approach to the beam a switch 45 is in its central position so that signals from the pick-off 32 of a directional gyro 30, slaved to a flux valve compass (not shown), operate a servomotor 51 to maintain the output of an inductive transformer 35 zero so that it has no effect on either the aileron servosystem 26 or a rudder servo-system 58. When the aircraft is stabilized on the beam, however, switch 45 is moved manually or automatically to the position shown, thus introducing an attenuator 43 and showing the response of servomotor 51 so that only long-term heading variations, e.g. due to cross winds, are nullified. Signals corresponding to short term variations, e.g. due to gusts, are then applied from transformer 35 to summators 14 and 54 in the aileron and rudder servo-systems for damping purposes. Signals from yaw angular accelerometers 57 are also applied to the rudder servo-system. As the aircraft nears the runway the rate of displacement from beam signal is disconnected or applied through a filter (not shown). Just prior to landing, a radio altimeter or ground based apparatus operates a ganged switch 56 to apply signals from an inductive transformer 37 instead of those from transformer 35 to the rudder servo-system so that the heading is aligned with the direction of the runway selected by a knob 61 associated with transformer 37. Under these conditions the signal applied from transformer 35 to the aileron servo-system causes the windward wing of the aircraft to drop but the maximum bank angle obtainable by virtue of a limiter 16 is reduced by the operation of switch 68. Switch 45 is provided with an off position so that normal control of the rudder by the directional gyro is available when required. Introduction of signals dependent on airspeed is referred to. Specifications 647, 469, 791, 987, 854, 732 and 942, 392 are referred to.

Title: Oil seals and method of making the same
IPC: F16J15/32
Filed: 1948-02-20
Abstract: 650,572. Stuffing-box substitutes. GARLOCK PACKING CO. Feb. 20, 1948, No. 5107. Convention date, April 8, 1947. [Class 122(v)] In an oil seal 11 for sealing an annular space between vertically rotatable outer and inner machine elements C, A, a sealing element 13 has a sealing ring of soft flexible moulded material with a portion 22 for making a securing seal with the inner element A, an integral radial flange 21 and a supporting ring 23 of U-shape cross-section disposed with the concave part of the U facing inwardly and substantially completely occupied by and bonded to the material of the flange 21; a rigid shell 12 having a cylindrical portion 16 to press fit into the element C has a radial flange 18 extending at least to the radial inward extension of the ring 23; clamping means, including a filler ring 15 having an annular radial surface at the side of the flange 21, remote from the radial flange 18, and extending radially over at least an area corresponding to the radial area between the outer and inner peripheries of the ring 23 co-act with the flange 18 to compress the flange 21 axially therebetween. The U arms of the ring 23 are of greater radial dimension than the spacing between the arms and have a tendency to be urged together by the axial compression to supplement the bond between the sealing ring 20 and the supporting ring 23 to prevent radially inward displacement of the flange 21. One arm 23a of the ring 23 is embedded in the flange 21 and the other arm 23b is partially embedded in one side face of the flange 21, the other side face being in sealing contact with the flange 18 of the shell 12. In a further embodiment, the outer diameter of the element 13, Fig. 2, is less than the inner diameter of the portion 16 of the shell 12 and a filler ring 29 of substantially the same capacity for resisting the clamping face is provided to fill the space between the element 13 and the portion 16. In a further embodiment the arms of the supporting ring are fixed to the opposite side face of the radial flange of the sealing ring. An annular spring carrier 14 may be employed. A method of making the sealing element by moulding is described. Specification 612,830 is referred to.

Title: Improvements in tobacco boxes with cigarette rolling devices
IPC: A24C5/44
Filed: 1920-02-20
Abstract: 139,212. Zadina, J. June 4, 1914, [Convention date]. Boxes combined with cigarette-making devices; partitioned boxes. - A tobacco-box is provided with a cigarette-making device comprising an apron wound on a spring roller and working in a trough-shaped member in the box. The whole is mounted in a casing f which is secured in the box by the hinge-pin of the lid, but can be withdrawn for cleaning, being then slid under the turned-over edges of the box to a place where these edges are cut away. The roller rotates on a spindle fixed to the ends of the casing f and carries a ratchet-wheel b with which engages a spring pawl. The apron passes through a slot at the top of the trough-shaped portion h of the casing f and previous to use is drawn out, thereby winding-up a spring enclosed in the roller. The tobacco is then placed on the apron in the trough h, a cigarette paper placed in position, and the lid closed down. This last action releases the pawl which engages with the ratchet b and allows the spring to roll up the apron on the roller, thus forming the cigarette.

Title: Improvements in the manufacture of lace on twist-lace machines
IPC: D04C5/04
Filed: 1919-03-04
Abstract: 137,421. Morris, J. J. March 4, 1919. Lace.-In the production of Valenciennes lace in machines employing a full set of bobbin threads and a right and reverse-twist warp-thread to each, the whole of the threads work in pairs and the two half-sets of right-twist warps A, A<1>, instead of being traversed over two carriages as usual, are traversed over four gates. The bobbin threads C are thus drawn in pairs over four gates, and a more solid and even bobbin fining effect, presenting a greater contrast to the net, is thus obtained. The reverse-twist warps B also work in pairs, are traversed two gates in reverse direction each motion, and interweave in pairs with the crossing bobbin threads C at points between the pairs of warps A, A<1>. In making half-fining work, the warps A, A<1> are traversed four gates every alternate motion and two gates on the remaining sections. The facing-bar is brought forward in front of the centre of the machine a sufficient distance to ensure the large amount of thread that is necessary with this system of working being drawn off the bobbins each time the carriages move from front to back. The improved bobbin fining can be produced in conjunction with any ordinary net or ground or with diamond nets made in ten, twelve, or more motions by working the warpthreads in pairs, as described above. Figs. 2 and 3 show such nets made with two-motion ties and single ties respectively. The bars of the nets are each composed of six threads twisted together, i.e. pairs of threads A or A'. B and C, and are stronger, and the connexions are more secure than in nets as ordinarily produced.

Title: Tyre bead retainer and method of positioning the retainer and a tyre on a wheel rim
IPC: B60B21/12
Filed: 1976-02-11
Abstract: 1505000 Preventing tyre bead displacement GOODYEAR TIRE & RUBBER CO 11 Feb 1976 [9 June 1975] 05349/76 Heading B7C A device 10 for preventing the displacement of tyre beads 14, 15 into the well of a wheel rim 22 comprises a band 11 of resilient flexible material, e.g. steel or fibre-reinforced plastics, a plurality of bead spacer members 12 mounted on the band, and means for drawing the ends 17, 18 of the band together. In assembling the illustrated device with the tyre and rim the band 11 is first radially contracted by gripping its ends 17, 18 and urging them together, and is then inserted into the tyre cavity. The ends of the band are then released so that band expands radially by virtue of its resilience and the members 12 engage the inner surface 19 of the tyre tread portion as shown in Fig. 1. Thereafter one bead 15 of the tyre is mounted on the rim 22 in conventional manner and a cable 24 connecting the ends 17, 18 of the band is passed through a valve hole 34 in the rim. The other bead 14 of the tyre is then mounted on the rim and the beads are seated on the bead seats of the rim, e.g. by injecting air through the hole 34. The ends 17, 18 of the band 11 are then drawn together by pulling on the cable 24, thereby wrapping the band 11 tightly around the rim within the well as shown in Fig. 3. Finally the portion of the cable 24 extending through the hole 34 is cut off and the cut end placed inside the tyre cavity so that an inflation valve 35 can be fitted in the hole 34. Once wrapped tightly around the rim the band 11 is prevented from expanding by a locking device 25 comprising a pin inclined to the cable 24 which allows movement of the cable to draw the ends 17, 18 together but bites into the cable if there is movement of the latter in the opposite direction (see also Fig. 5). Thus to remove the type and device 10 the cable 24 must be cut.

Filed: 1932-02-23
Abstract: 389,642. Variable-speed gearing. STEVENS, A. H., 5, Quality Court, Chancery Lane, London.-(Free Wheeling Patents Corporation; South Bend, Indiana, U.S.A.) Feb. 23, 1932, No. 5374. [Class 80 (ii).] In a transmission gear for automobiles the drive for both the first and second high speeds may be either one way or two-way. As shown, a coil spring 26 connects the driving-shaft 3 with a free ring 27. A collar 21 splined to the driven shaft 5 has teeth 23 permanently engaging teeth on a sleeve 24. The latter has teeth 31, 29. A gear 15<1> free on the shaft 5 and driven from a countershaft 11 is connected to a free ring 20 by a coil spring 19. The rings 27, 20 have teeth 28, 22, and the gear 15<1> has teeth 30. In operation, a movement of the sleeve 24 to the left locks the ring 27 to the collar 21, and the drive is a one-way one through the spring 26 from the shaft 3 to the shaft 5. A further movement of the sleeve 24 to the left brings the teeth 31 into engagement with teeth 32 on the shaft 3, and the drive is a two-way one from the shaft 3 to the shaft 5. Similarly, a movement of the sleeve 24 to the right produces a one-way drive through the spring 19 from the gear 15<1> to the shaft 5, while a further movement of the sleeve 24 to the right locks the gear 15<1> to the collar 21 to produce a two-way drive. The driven shaft 5 also carries a gear 33 which may be engaged with a gear 15 to produce a third speed or may engage an idler 34 to produce a reverse speed.

Abstract: 1430973 Hydrocracking EXXON RESEARCH & ENG CO (K J VERYARD) 5 Feb 1973 5585/73 Heading C5E A feed containing aromatic hydrocarbons is hydrocracked, the hydrocracked material is fractionated to provide an aromatic naphtha and a bottoms stream, the bottoms streams is hydrocracked separately, this hydrocracked material is fractionated to provide a turbine fuel of low aromatics content and a second bottoms stream, at least part of which is recycled as part of the feed to the second cracking step. Both hydrocracking steps are over catalysts comprising palladium supported on a zeolite of specified composition. The feed to the first hydrocracking step includes amounts of H 2 S and NH 3  within specified ranges, these may be the products of an earlier hydrofining step; the feed to the second hydrocracking step also includes an amount of H 2 S within a specified range. These amounts and the temperature, pressure, space velocity and hydrogensupply rate in each cracking step are correlated to obtain specified figures for hydrogen consumption and conversion. The feed may be a heavy coker naphtha, a coker gas oil, an aromatic virgin gas oil or a mixture of catalytic heating coil and gas coil. As shown, the feed (100) together with recycled hydrogen (116) and make-up hydrogen (118) is hydrofined at 102 over a catalyst of cobalt and molybdenum oxides on a silica-alumina support. The whole effluent from this zone, including H 2 S and NH 3 , is taken to zone 108 and hydrocracked. The product is cooled at 112 and flashed at 114 to separate a gas comprising hydrogen with some H 2 S and NH 3  for recycle. The liquid from the flash is fractionated at 122 to provide light ends (124), aromatic naphtha (126), an aromatic turbine fuel (128) and a bottoms fraction (123) that is sent to the second hydrocracker (130), together with recycled hydrogen (138), make-up hydrogen (140) and H 2 S (142). The product from 130 is also cooled (134), separated (136) and fractionated (146) to provide hydrogen for recycle (138),light ends (148), naphtha low in aromatics (150), turbine fuel low in aromatics (152) and bottoms (154) which are recycled to 130. The turbine fuel low in aromatics (152) can be used by itself, or blended with the aromatic turbine fuel (128). The naphtha low in aromatics (150) can be reformed and blended with the aromatic naphtha (126) for use as motor gasoline. The aromaticity of the naphtha from the second stage can be adjusted by adjusting the concentration of H 2 S in that stage. Reference has been directed by the Comptroller to Specification 996,428.
