IPC: E21B10/22
Abstract: 1,051,095. Bearings. HUGHES TOOL CO. April 2, 1964 [April 22, 1963], No. 13671/64. Heading F2A. [Also in Division E1] In an earth-boring drill (Fig. 1, not shown), each of a plurality of rotary cutters 10 is supported on a pin 9 by a thrust bearing 14, a ball bearing 17, a roller bearing 18 and a plain bearing comprising a bushing 5 which engages with a cylindrical surface 16 on said pin and is made of a hard wear-resistant material having the hardness and wear-resistance of a carburized heat-hardened alloy-steel, e.g. high carbon steel, or mixtures of compounds such as carbides of tungsten and other metals adjacent thereto in the Periodic Table. The inner surface 1 (Fig. 3, not shown) of the bushing 5 comprises slots filled with a soft anti-galling metal 2, e.g. silver or a silver alloy, the slots being either straight and parallel to the axis of rotation of the cutter or helical (Fig. 3A, not shown). Alternatively, the surface 16 on the pin 9 is made of hardened steel in which axiallyorientated grooves are cut and filled with a soft anti-galling metal 39 (Figs. 4 and 4A, not shown). Lands 40 between the grooves may include bands 40<SP>1</SP>made of a hard alloy having a base of, e.g. iron or cobalt. The ball bearing 18 may be replaced by a plain bearing (Figs. 5A to 5E, not shown) wherein grooves or indentations in the bearing surface on the cutter are filled with soft anti-galling metal 23 . . . 23<SP>IV</SP>. Alternatively, the corresponding surface on the pin 9 includes a plurality of grooves 69 or 69<SP>1</SP> (Figs. 6A and 6B, not shown) filled with soft anti-galling metal. The thrust bearing 14 may comprise a button 14<SP>1</SP>(Fig. 10, not shown) lodged in the cutter and engaging with a surface 15 on the end of the pin 9 which has a coating 41 (Fig. 9, not shown) which is made of a cobalt-based alloy and includes recesses (not shown in the drawings) filled with soft anti-galling metal. Alternatively, the button 14<SP>1</SP>includes an eccentrically situated annular groove 27 filled with soft anti-galling metal which engages with the surface 15. A further thrust-bearing surface 41<SP>1</SP>on the pin 9 may include recesses 42 filled with soft anti-galling metal. Other examples of a soft anti-galling metal are lead, tin, copper, antimony, rhodium, platinum, palladium, gold, indium, bismuth, beryllium, zinc and aluminium. Lubrication of the ball bearing 17 is effected through passages 30, 31, 32 by a proportion of gaseous cooling medium which is supplied to the cutters 10. 'If the cutters are supplied with a liquid cooling medium, the bearing 17 is lubricated by grease which is lodged in passages 34, 35, 32 (Fig. 2, not shown) and driven into the bearing by a capsule 33 expanding when the pressure of said medium surrounding the cutters increases in accordance with the downward progress of the drill in the bore-hole. The lubricant supplied to the bearing 17 also serves to lubricate the other bearings.

Abstract: 1,231,528. Light responsive circuit. ATES COMPONENTI ELETTRONICI S.p.A. Nov.26, 1969 [Nov.26, 1968], No.57819/69. Heading G1A. A light responsive circuit, Fig .1, substantially independent of temperature and supply voltage variations includes a photo-diode F. D .1 which controls the input of an amplifier, the amplifier comprising a first transistor Q 1  connected in the common collector mode and arranged to control the signal applied to the base of a second transistor Q 2  the first and second transistor being connected so that the signal between the points A and B is equal to the difference between the base emitter potentials of the two transistors (causing the transistors to be independent of temperature variations). The circuit components are arranged so that the photo-diode F. D .1 and the transistor Q 1 , Q 2  are effectively in the diagonal of a resistance bridge WXYZ (ensuring the circuit is substantially independent of supply voltage variations). A relay RL 1  is controlled by the output from transistor Q 4 , Q 3  and Q 4  forming a second amplifying stage, such that when the ambient light impinging on photodiode F.D.1 falls below a predetermined level, the relay RL 1  operates, for example, to turn on the side lights of a vehicle, and, simultaneously the contacts rl, of a further pair of normally open contacts, are closed. The closing of the contacts rl, applies a signal to the emitter of transistor Q 4  which requires that the level of light impinging on the photo-diode F.D.1 should rise above the first predetermined level to a second predetermined level before the output signal of the circuit as a whole is removed, i.e. before the side lights are switched off.

Abstract: 1,232,109. Air cushion vehicles. SOC. DE L'" AEROTRAIN". 9 Aug., 1968 [15 Sept., 1967; 19 June, 1968], No. 38218/68. Heading B7K. A tracked air cushion vehicle has a cushion containing skirt system whose position relative to the supporting track surface is determined by a spring and damping system. A flexible skirt member 2 is attached by bolts 9 to a U-shaped member 8 which is pivotally attached by brackets 10 to an extension 7 of the vehicle body at 4. Also attached to the U-shaped member 8 are two flexible diaphragms 11 and 13, which enclose an airspace 5 which communicates with the main air cushion 1 through holes 12. A second skirt member 14, which is normally further from the track surface than is the skirt member 2, is attached to the vehicle body 3, as are diaphragms 11 and 13. Clamped at 16 to the vehicle body extension 7 are torsion bars 15 which pass through bearings 17, the bearings having sufficient friction to damp motion of the torsion bars. When an obstacle is encountered by the vehicle so that skirt member 2 is lifted away from the track surface, the torque exerted by the torsion bars on the member 8 increases; this increase in torque may be matched by the increases in torque of the air pressure forces acting on diaphragm 13 so that overall cushion stiffness is maintained, Fig. 2 (not shown). If these torque increases are not matched, the decreased clearance between track and skirt member 14 may be used to stiffen the innermost portions of the air cushion. Damping of vibrations of the skirt occurs due to the torsion bars and their bearings, and because pressure variations in the air space 5 are out of phase with those in the cushion 1. The torsion bars may be supplemented by hydraulic rams, Fig. 3 (not shown), and additional damping may be derived from a matched resonator attached to the U-shaped member 8, Fig. 4 (not shown). The invention may be used without the diaphragm 11.

In this way the discharge path 14 is made to vibrate faster than the feed path 13 so that the articles tend to be more separated. Additionally, bath 14 is of a different slope or of different frictional material to achieve the aim of conveying faster than the feed path 13. A device (not shown) may be provided on the path 14 for orienting the articles. The conveying path may be a straight line track.
