Title: Improvements in or relating to gyroscopic apparatus
IPC: G01C19/44
Filed: 1942-10-22
Abstract: 560,478. Gyroscopic apparatus. SPERRY GYROSCOPE CO., Inc. Oct. 22, 1942, No. 14843. Convention date, Aug. 6, 1941. [Class 97 (iii)] A gyroscope having three degrees of freedom, for example, a gyro-vertical or a directional gyroscope is erected by a torque having components about both horizontal axes thus counterbalancing the effect of friction at the gimbal bearings and giving a straight line erection movement. In Fig. 3 is shown a cross-sectionthrough the erection devices of an air-erected gyro vertical. The air slots 7, 7<1> and 8, 8<1>, which co-operate with the pendulums 9, 91 and 10, 10<1>, instead of being arranged perpendicularly to the trunnion axes of the gyroscope as usual, are arranged as shown at an inclination thereto so that during an erecting movement, in addition to the main torque, a small component torque is produced about the precession axis in order to counteract the friction torque opposing precession, thus resulting in a straight line erection movement..In a modification, the small component torques are produced by auxiliary ports. The invention may be applied to a directional gyroscope wherein the rotor 32, Fig. 6, is spun by an air jet 46 and is erected relative to the vertical ring 38 by the impingement of the jet against lateral walls 47, Fig. 7, on the rotor, as described in Specification 394,412. According to the present invention, the jet is arranged to strike the rotor above or below the trunnion axes 36, 37 of the gimbal ring 35 so that a small component torque is provided to oppose the frictional torque. Specification 393,695 also is referred to.

Filed: 1920-06-01
Abstract: 144,282. Corning Glass Works, (Assignees of Churchill, W.). Jan. 22, 1916, [Convention date]. Signal lanterns.-In a lamp projector, more particularly a railway signal lamp for use during daylight as well as at night, external light is prevented from being reflected forwardly by the lamp towards the zone of observation by fixing a cover glass 8, preferably of yellow glass and with a convex front surface, in front of the lens 7 and arranging a hood 10 to project forwardly over the cover glass 8. The outer surface of the cover glass is preferably conoidal and its apex is sand-blasted or etched. The lens 7 is preferably a Fresnel lens with its stepped surface arranged outwardly, and different sections of the lens may have different refractive power, as described in Specification 137,962, [Class 75 (ii), Lamp chimneys &c.]. In one form of lamp for giving a standard signal, the refractive faces 7<c> of the lower and side portions of the lens 7 have a greater radius of curvature than the corresponding faces of the upper portions, so that the upper portions have greater refractive power than the remainder. The light source is located at the approximate principal focal point of the upper sector of the lens and in front of the principal focal point of the lower parts, and a mirror 9 is arranged above the axis of the lamp with its centre above this axis and in front of the light source. Part of the upper surfaces 7<m> of the prisms in the lower portion of the lens may be blackened, and these blackened surfaces are arranged substantially parallel to the path of rays passing through the corresponding part of the lens. When using an electric light source, a spherical lamp bulb 6 having a smooth upper end is employed with the centre of curvature of the bulb below the axis of the lamp, but with its narrow horizontal coiled filament 6a arranged with its axis at right-angles to the axis of the lens and intersecting it at the focus of the upper sector of the lens. The cap 22 of the bulb is vertically adjustable in a sleeve provided with the usual projections for engaging slots in the holder and is soldered in the sleeve when the bulb is adjusted in position. A diaphragm 28 may be arranged within the lamp casing, the interior surface of which is blackened. When using the lamp in a signal to be observed from above, the position of the different parts of the lens and of the mirror in respect to the principal axis of the lamp is inverted.

Abstract: 1386252 Change-speed control CAV Ltd 5 May 1972 [14 May 1971] 15037/71 Heading F2D A driver-operable gear selector unit for controlling a remote multi-ratio gear-box is provided with means for preventing movement of the selector lever 13 into neutral or into an extreme position until the selector mechanism of the gear-box has effected the appropriate change in the gear-box mechanism. The lever 13 is pivotally mounted on a rotatable shaft 11 which is associated with switches, each operable to effect energization of the appropriate selection means of the gear-box, and on which is mounted a plate 15 having an aperture 16 formed with stops 18-20. A peg 21 located within the aperture 16 is secured to a plate on an armature 23 associated with a solenoid 25. As the lever 13 is moved away from the neutral position, a cam roller 26 on the peg 21 rolls out of a recess in the periphery 27 of the aperture, thereby moving the peg 21 against the action of a spring 24 to a position to intercept the stops, and the solenoid 25 is energized by means of a switch in the housing, thereby holding the peg in its intercepting position. When the appropriate gear ratio of the gear-box is correctly selected, the solenoid is de-energized, allowing the lever 13 to be moved to its extreme position in which the roller 26 engages in a further recess in aperture periphery 27. Similarly, the peg 21 is held in an intercepting position on movement of the lever 13 from an extreme position towards the neutral position.

Title: Process for the production of bi-metallic sheets
IPC: B23K20/04
Filed: 1975-04-14
Abstract: 1445077 Rolling composite slabs T SENDZIMIR 14 April 1975 15280/75 Heading B3M A composite strip having a plurality of layers of metals is produced by rolling a pack of slabs 1, 2 in a planetary mill, the pack being subject to high intensity heating (which is insufficient to cause melting) immediately before rolling. Feed rolls 5, 5<SP>1</SP> are provided upstream of the mill, and planishing rolls 9, 9<SP>1</SP> downstream. The slabs 1, and 2 may be of mild steel and may have stainless sheets 3 and 4, Fig. 5, positioned between them. A stop weld material 3<SP>11</SP> such as magnesium oxide prevents bonding between the sheets 3 and 4, and results in two composite sheets each of mild steel with one facing of stainless steel. In an alternative arrangement of slabs, three low carbon slabs (Fig. 3, not shown) are separated by bands of stop weld material, such that after rolling the resulting composite can be expanded by air pressure to form a cellular structure with either flat or corrugated outer surfaces. Alternatively, the three slabs may have a pair of stainless steel sheets positioned between each of their interfaces (with stop weld material between each pair of sheets). Three low carbon sheets are then provided, two with a stainless cladding on one face, and one with a cladding on both faces. The slabs may be heated by a gas mixture of butane and oxygen yielding high temperature flames. The resulting combustion products are fed between the slabs and insulating plates 7, 7<SP>1</SP> to prevent oxidation of the slabs. Very high frequency induction heating or electron beams may be used in place of the gas mixture. The heat applied to the slabs is designed to bring the slabs to oxidation temperature throughout their thickness only when they reach the region R-R where reduction begins. The slab temperature may be allowed to rise during rolling or may be held constant at 600‹ to 700‹ C. (for low carbon steel).

Abstract: 428,895. Thermally-actuated valves. TAILLEFERRE, H. E., 93, Rue Jouffroy, Paris. May 23, 1934, No. 15390. [Class 135] [See also Group XIII] In a thermally-operated valve, a flexible bellows 2 is fixed at the upper end to a tube 4 and at the lower end to a tube 3 which are free to move relatively with slight clearance. The tube 4 is adjustable within the body 6. The bellows 2 contains a volatile liquid, the vapour pressure of which acts on an immiscible liquid, e.g. oil, in the tube 4. A stopper 9 enables the air volume above the oil to be regulated, and the opening 10 may be sealed with lead. The valve is suitable for controlling the outlet of a radiator. In a modification, the tube 4 extends upward and contains a piston which moves upward as a result of increase in pressure of the vapour of the volatile liquid. An adjustable stop limits the movement of the piston at a predetermined temperature of the volatile liquid, and the valve is then actuated. In another modification, the stopper 9 is replaced by an adjustable bellows. In another modification, Fig. 5, the thermostatic element is connected by pipe 29 to a bellows 42 which actuates a piston valve 40 in the passage of the fluid to be controlled. An adjusting member C comprises a bellows 45 subjected to a hand-set cam. In another modification, Fig. 6, two concentric tubes 46 are coiled into a spiral, and the volatile liquid is placed in the space between the two tubes. The innter tube contains the pressuretransmitting liquid, which extends into the chambers 49<a>, 51, and through the tube 55 to the valve. An adjusting device, Fig. 7, which is also connected to the tube 55, comprises a corrugated tube 61, the free upper end of which carries a member 65 sliding in the tube 64 and in contact with an eccentric cam 67 which is integral with the manually-rotatable casing 68.
