Title: Gyroscopes, gyroscope stabilised systems and gas bearings for the same
IPC: G01C19/00
Filed: 1958-06-03
Abstract: 884,061. Fluid bearings. STANDARD TELEPHONES & CABLES Ltd. June 3, 1958 [June 3, 1957], No. 17692/58. Class 12 (1). [Also in Group XX] A gyroscope comprises a rotor 1, Fig. 1, adapted to rotate about an axis 2, an intermediate frame 4, and gas bearings for the rotor 1, so that it has two degrees of freedom of tilting of its axis, and means for steadily rotating both the rotor 1 and the intermediate frame 4 with respect to a main frame, which is intended to remain approximately rotationally fixed in space, so that processional drifts resulting from static torques of the gas bearings are continually neutralized. As shown, the rotor 1 is supported by six bearing pads 3, gas being supplied through the manifolding 5 to the reservoirs 6 within the pads 3, and fed through the almost microscopic feed holes 7 to the bearing surfaces. The rotor 1, which is hollow, has two cylindrical cavities 2 which define the axis of rotation and are used with the pick-off system which may be capacitive or photoelectric. The intermediate frame 4 is mounted in mechanical bearings and spun by some external driving mechanism such as an electric motor or gas turbine system, and the rotor 1 may be secured by a caging mechanism, not shown, to the intermediate frame 4 during both the spin-period and also the slow-down period. When the operating speed is reached, the caging mechanism releases the rotor 1 which is then supported solely by the gas bearings. The signals obtained from the pick-off arrangement, are used to maintain the intermediate frame 4 in line with the rotor 1 about all axes except the axis of rotation, and the rotor may be spun at a speed different from that of the intermediate frame 4, for example at a higher speed. In a modification, Fig. 5, in which the rotor and intermediate frame rotate at the same speed, the six bearing pads 27, support a sphere 39 which is connected by spokes 40 to an external rotor 38, and high pressure gas is supplied through manifolding 29 into feed tubes 30 and high pressure chambers 31. The gas passes to the bearing surface through the very minute feed holes 32 and leaves through a ring 28 and vacuum chamber 34. A still higher vacuum is maintained in the case 36. In another embodiment in which there are eight bearing pads, each has three chambers 51, 52, 53, Fig. 12. High pressure gas from chamber 51 passes through holes 89 and is mostly received by the inner ring 91, to which a moderate suction is applied through chamber 52. Chamber 53 applies a considerably higher suction to the second ring 93 through the connecting holes 94. A still higher degree of vacuum is applied to the casing in which the bearing pads and rotor are mounted. In a modification, the casing instead of being spherical may be flattened at the top and bottom and the rotor may have a corresponding configuration.

Title: Sheet collator
IPC: B65H39/042
Filed: 1961-05-19
Abstract: 928,318. Sheet collators. LINDACO A.B. May 19, 1961 [May 24, 1960], No. 18297/61. Class 100 (1). A sheet collator comprises a plurality of bins 1 each arranged to hold a stack 5 of sheets on edge, each bin having a sheet flat side support 2 at an angle to the horizontal and at the upper edge thereof anti-friction means, e.g. a roller 16, the bins being so positioned that the antifriction means lie in a common plane, and a sheet ejector 3 arranged in each bin to project a portion of the outermost sheet of each stack from the bin above the common plane. Each ejector has a rubber lip 4 which rests on the stack 5, and is pivoted at its lower end to a horizontal rod 6 which is supported by parallel links 8, 15 pivoted on axles 11, 14. A lever 9 also pivoted on the axle 11 and rigidly connected to the link 8 is biased by a spring 10 towards the position shown and is connected by a wire 12 to a pedal 13. Depression of the pedal causes the ejectors to descend in the bins and upon release of the pedal the spring 10 raises the ejectors again whereby the upper end of the outermost sheet in each stack 5 is raised above the level of the corresponding roller 16, being bent over into contact with the roller by a pivoted guide member 17. The operator then draws a pad 18, which has a rubber or like friction surface, in the direction shown by the arrow over the track formed by the rollers 16. The pad bends the upper portion of the first sheet over its roller and pulls the sheet out of the bin; the first sheet is carried along by the pad until it bends the second sheet over its roller and pulls it out of the bin, and so on until the whole set of sheets has been assembled in a single movement. The operator then grasps the collated set of sheets and is ready for the next collating operation. The track formed by the rollers 16 may be inclined to the horizontal. The collator may be operated semi-automatically if a wire is used to connect the left-hand end roller 16 to the lever 9 ; as the pad 18 is moved over the roller the wire is wound round it so that the lever 9 is actuated to lower the ejectors in the bins. When the pad is raised from the roller the ejectors are operated by the spring 10. The movement of the pad may be mechanized.

Title: Improvements in Electric Cable Grips.
IPC: H02G15/013
Filed: 1917-12-15
Abstract: 121,358. Henley's Telegraph Works Co., W. T., Nichols, W. H., and Moor, E. Dec. 15, 1917. Couplings.-For securing and, if necessary, electrically bonding an annular layer of an electric cable to a junction-box or other electric apparatus, a conical gripping-block, comprising a metal shell 11 in halves and lined with soft metal 12, is adapted to be clamped tightly about the cable by an internally coned gland 17 which is forcibly drawn over the block in the direction of the apparatus as by nuts and bolts 20, 18. In order to fill the shell, the two sections are held in a mould at a small distance apart, and molten lead is poured in to fill the shell, the end apertures, and the space between the edges of the sections. After the lead has cooled, the filling is drilled to fit the bared portion of the cable, and the sections are sawn apart through the lead in the interspace. The end of the block coming into contact with the box is preferably coned, as at 21. and may bed upon a flanged ring 22 or enter a flared opening in the box side 15. When the cable armouring consists of wires, they are arranged to be gripped between the gland and the block, and. to render the grip more secure, the outside of the shell may be circumferentially corrugated. The inside of the shell may also be corrugated to afford a better hold for the lead lining. In the case of a cable having a lead sheathing within a metallic-tape armouring, the armouring may be cut short outside the box and bonded to the box by the block 11, the lead sheathing being arranged to extend into the box and to be connected thereto as by a copper clip fixed to a boss on the inside of the box. In order to make a plumber's wiped joint with the lead sheathing 29, Fig. 5, of a cable, a wiping- gland 28 is passed over the sheathing within the gripping-block before the block is drawn up by the gland 17. The wiping-gland has at one end a flange 30 which is adapted to be clamped between the gripping-block and the box side, and at the other end a number of tongues 32 bent inwards to contact with the sheathing. In order to secure and bond both the lead sheathing and the metallic-tape or wire armouring of a cable to a box, a pair of gripping-blocks each provided with a separate gland may be employed, one block and gland serving for the sheathing and the other block and gland for the armouring. The two blocks may be tightened by nuts on bolts engaging with both glands; or the gland of the block nearer to the box may be arranged to be engaged by the second block as this is drawn up and tightened by nuts and bolts engaging with the second gland.
