Title: Improvements in or relating to Apparatus for the Conveyance of Strip Coils or Other Rolled Stock from a Feeding Point to a Further Conveyor or Processing Line
IPC: B21C47/24
Filed: 1967-04-20
Abstract: 1,162,591. Reciprocating conveyers. VEREINIGTE OSTERREICHISCHE EISEN-und STAHLWERKE A.G. 20 April, 1967 [17 May, 1966], No. 18273/67. Heading B8A. Strip coils or other rolled stock 7 are accurately located on a forked lifting table 3 before being conveyed step-by-step on an hydraulically reciprocable beam 1 towards a conveyer 5, 6. The beam 1 is provided with two sensing levers 8 urged by springs 11 into the symmetrical position shown in Fig. 4 and a switch 15 is controlled by the levers. If a coil 7 is accurately deposited on the table 3, the levers 8 will be uniformly depressed and the switch remain unoperated. If the coil is deposited, e.g. in the position indicated in dashed line in Fig. 1, one of the levers 8 is depressed more than the other and the switch 15 will cause an hydraulic piston actuator 2 to move the beam 1 such that the levers 8 assume a symmetrical position. The coil is thus accurately positioned and the table 3 is lowered to deposit the coil on the beam 1. By full stroke reciprocation of the beam and vertical movement of further lifting tables 4, coils are fed to the conveyer 5, 6. Figs. 6-8 (not shown) illustrate modifications of sensing levers.

Abstract: 787,362. Collapsible tower cranes. MASCHINENFABRIK AUGSBURG-NURNBERG AKT.-GES. June 24, 1955 [June 24, 1954], No. 18352/55. Class 78 (4). A slewing-jib tower crane carried by wheeled arms 2, 3, Fig. 1, from the ground or from rail tracks 5 when in use can be dismantled, and its tower lowered to be supported on a carriage 11, Fig. 3, while its platform 1 can be transferred to a road vehicle 7. As illustrated, jacks 71, Fig. 3, on the platform 1 and engaging the vehicle platform are used to raise the wheels 4 so that the arms 2, 3 may be raised about pivots 8, Fig. 1, to the position shown in broken lines in Fig. 1. Alternatively, however, the arms 2, 3 may comprise jacks which serve to transfer the weight of the crane between the wheels 4 and the platform of the road vehicle 7. The jib 10 is lowered until the jib end pulley 38 rests on the ground by drawing in the load cable 19 until it engages the pulley 38 and then disconnecting the luffing cable 20 to permit the load cable 19 to be used to lower the jib. The load cable 19 is then unreeved from the pulley 38 and connected to lower the inner end 39 of the jib. The load cable 19 is then connected to the jib heel pivot 39 on the mast and employed to lower the mast about a hinge 42 when a fastening 40'has been released. The carriage 11 is secured to the jib heel pivot 39. The luffing cable 20 is broken at 35 before the crane is dismantled and the lower portion anchored at 37 to the mast. The jib may be carried on one side face of the mast as shown in Fig. 3. The mast 9 may comprise two telescoping parts, the lower formed of angle iron and the upper of tubes. A pivot 43, Fig. 3, may be freed, by removing struts from the tower, to permit articulation while travelling. The luffing cable 20, Fig. 1, is normally secured to a carriage 23 carrying a pulley 24 over which load cable 19 passes to provide level luffing. The carriage 23 carries a counterweight 27 and is moved along a guide 25 by a chain 29 driven from a motor 28 where the crane, when erected is to travel on a curved rail track, each of the arms 2 on the outside of the curve may be supported by a swivelling bogey having two wheels arranged in line and driven by a motor on the bogey while the arms 3 at the other side are supported by castor wheels.

Abstract: 126,339. Thomas, A. P., and Thomas, S. Dec. 22, 1916. Projectile fuses.-Relates to percussion fuses which are armed on discharge by the projection from a surrounding sheath of the part (e.g. the firing-pin) that co-operates with the inertia pellet, and consists in the provision of a blocking- device such as a ball, which has no locking engagement with the striker or like part, but moves behind this part when in the armed position so as to retain it there. In the fuse which is shown in Fig. 1 in unarmed condition, the cast-iron body a has a bore of varying diameter. The bore may pass completely through the fuse body, being subsequently closed at the outer end by a plug. In the smallest chamber e is a ball or the like g resting against the head h (or a bass u thereon) of the firing.pin j. This pin is sheathed by a sleeve m, but on discharge of the projectile, it sets back against the action of the spring k, so that its point protrudes beyond the flange l of the sheath. The ball g becomes lodged between the head h and a shoulder e<1>, retaining the firing-pin in the position in which it can coact with the inertia. pellet p on impact.

Title: Improvements in or relating to gyroscopic systems for controlling dirigible objects such as aeroplanes
IPC: G01C19/00
Filed: 1925-07-18
Abstract: 365,187. Automatic steering of aircraft ; gyroscopic apparatus. MEREDITH, F. W., Royal Aircraft Establishment, South Farnborough, Hampshire. July 18, 1925, No. 18387. [Class 4.] In a gyroscopic system comprising an azimuth gyroscope for controlling through a servomotor and follow-up mechanism the rudder of a dirigible object such as an aeroplane, damping of lateral motion is effected by applying through the servomotor rudder angle determined by the displacement in roll of the craft relative to a free gyroscope rotor axis. This is achieved by tilting the plane containing the axes of freedom of the rotor other than of orientation. In one form, as shown in the Figure, X-X represents the fore and aft axis of an aeroplane the axis of spin 2-2 of the gyro rotor 1 being upwardly tilted in the forward direction from this axis. Rotation of the aeroplane about the axis X-X causes rotation of the azimuth ring 6 to operate the rudder servomotor. In a modification which may be used in systems wherein the orientation of the aeroplane can be changed without changing that of the rotor, the frame 8 is backwardly inclined so that the axis of rotation of the azimuth ring is normal to that of the inner gimbal ring 4. When the axis of rotation of the rotor is athwartships the inner gimbal ring is upwardly tilted at its fore end. An antitopple system may be applied to the gyroscope. Specification 365,186 is referred to.

Filed: 1935-06-28
Abstract: 455,805. Rotary engines. MARTIN, B. L., Martins, Abinger Common, Surrey. June 28, 1935, No. 18552. [Class 110 (ii)] A rotary internal-combustion engine (which may be modified to act as a compressor or pump) comprises an eccentric rotor b in a stator a, and vanes c which are pivoted through lugs c<1>, c<2> to a fixed spindle d. Cup-shaped members e are fitted on the spindle d and strengthen the vanes against centrifugal action through their flanges which are positioned within recesses c<3> in the vanes. Each vane slides between two D-shaped members g, g<1> which are journalled at their ends in the rotor. A clearance is provided between the vane tips and the casing. Air is admitted through a port h, compressed, and fuel is injected through one or more nozzles i. The gases expand and are exhausted through a port j. The port h is extended as shown to admit air to a space being exhausted, for scavenging purposes. Water for sealing purposes enters through a passage a<2> to a space g<6>, and feeds grooves c<5>, c<6> at the edges of the vanes, through grooves c' in the stator. Grooves g<6> prevent the water from entering the rotor. The grooves c<5>, c<6> communicate with grooves in the vane tips, which contain each a packing bar c<9> pierced by holes to permit entry of the water to the underside of each bar. Water also flows into a groove a<3> to seal the rotor. The water in the grooves forms into steam due to the high temperature of the metal. The groove a<3> may be shallow in the high pressure region, and deep in the low pressure region, and may be vented in the region of the exhaust port. The steam may be condensed and used again. Additional grooves for water are provided on the stator and rotor, arranged obliquely. Cooling jackets a<9> are provided in addition to flanges a<11> which may be enclosed to contain water. Oil may pass to the rotor through a hole f<6>, and leave by holes b<8>, or air may pass through. If combustion takes place in alternate vane chambers, the air in the idle chambers may be used for cooling purposes. Water may be injected into the working chambers. An additional impeller for supplying compressed air, may be provided on the working shaft. Gas may be used for sealing purposes in place of water. Combustion may take place in alternate chambers.

Filed: 1965-05-04
Abstract: 1,142,205. Magnetic recording and playback. ELECTRIC & MUSICAL INDUSTRIES Ltd. 4 May, 1966 [4 May, 1965], No. 18619/65. Heading G5R. A magnetic recording tape 3 is driven by capstans 1 2 which are rotated in opposite directions by an endless elastic belt 9 actuated by a motor 17 having a reversible drive. Belt 9 is tensioned by means of an endless belt 15 and pulleys 14, 16 in such a manner that when tape 3 is driven from left to right the tension in the loop of belt 9 round pulley 10 which drives capstan 1 is greater than that in the loop round pulley 11 which drives capstan 2. Conversely when tape 3 is driven from right to left capstan 2 rotates faster than capstan 1. This arrangement augments the tension in the tape loop between the capstans in both directions of tape motion and stabilises the drive of the tape. In a modification shown in Fig. 3, the capstans are driven by an endless elastic belt 9 formed of two layers 9<SP>1</SP>, 9<SP>11</SP>, layer 9<SP>11</SP> being of higher elastic modulus than layer 9<SP>1</SP>. Belt 9 is placed round pulleys 10, 11, 12 as shown, with layer 9<SP>1</SP> adjacent the lower face of driving pulley 12 and layer 9<SP>11</SP> adjacent the upper face of pulley 12. Due to the overall differential tension in the two loops of the combined belt the rate of rotation of pulley 10 is greater than that of pulley 11 for rotating in one direction and smaller for rotating in the other direction.

[Class 39 (i)] In a mercury-cathode discharge tube, having an anchoring body disposed in and partly emerging from the cathode mercury and arranged to localize the cathode spot at the limiting line of its free surface and the active surface of the mercury, tills active mercury surface is bounded on every side by one or more metallic bodies of good anchoring qualities that permanently emerge approximately to the same extent from the mercury surface and form an anchoring structure presenting a narrow channel the bottom of which is formed by the active part of the mercury surface. The channel which may have the shape of a closed figure is preferably of arcuate or zigzag form ; in the case of large mercury cathodes, the active surface may be housed in a number of concentric channels, radially interconnected, or the channel may be in the form of a spiral. The width of the channel is of the order of 1 cm. The cathode vessel 1 may be water cooled and the anchoring structure fixed directly to the bottom of the vessel. In the form shown, it comprises an internal nickel anchoring body 6 and an outer annular body 7, made internally from nickel and externally from molybdenum, and having recesses 8 formed in it so that mercury condensed on the vessel walls can now back to the annular channel between the bodies 6, 7. The cathode spot is anchored in this channel and, owing to the narrowness of the annular spaces outside the body 7 and the fact that it is bounded by surfaces having no anchoring effect, the discharge is prevented from settling therein.
