Title: Improvements in or relating to adjusting devices for sighting telescopes
IPC: F41G1/38
Filed: 1938-02-08
Abstract: 511,195. Telescopes. KAPELLA, Ltd., and REASON, R. E. Feb. 8, 1938, No. 3908. [Class 97 (i)] An adjusting device for a sighting telescope whereby the optical axis of the telescope, or an image of such axis, can be brought into alignment with two fixed remote points, or at least into a plane containing them, comprises means whereby a small movement can be imparted to the optical axis, or its image, to bring it into alignment, or into a common plane, with one of the fixed points whilst maintaining it in alignment, or coplanar, with the other fixed point. Figs. 1 and 2 show one form for bringing the telescope into the vertical plane containing the two fixed remote points x. y, Fig. 3. The telescope B is fixed on a carriage B<1> provided with balls B<2> resting on a base plate A so that the carriage is freely movable over the plate which can rotate about a vertical axis A<1>. Rollers C', C<2> mounted on the plate A coact with straight guides D<2>, D<2> secured to the carriage B<1>, the angle between the guides being adjustable by. a screw B<3>, and the telescope being so mounted that its axis bisects this angle. The plate A is placed with its axis more or less in line with the points x, y, and at a known distance from y and is adjusted about its axis until the rollers C<1>, C' are more or less equidistant from the vertical plane containing the points x, y and the guides D<1>, D<2> are adjusted to an angle whose sine is equal to c<1>c<2>/2dy. With this adjustment the points c', d, c<2> lie on a circle having its centre at y, so that, if the telescope is initially sighted on y, it will remain so sighted whilst the carriage is moved until the telescope is also sighted on x. In the form shown in Figs. 10 and 11, the telescope J and a mirror J<2> are fixed on the base J<1> and the adjusting device acts on a mirror K mounted on a support L which is freely movable on the base and is constrained by the engagement of rollers L<1>, L<2> on the support L with guides M', M<2> on the base, the roller L<2> being immediately below the mirror K and the roller L' being between the mirrors K, J<2>. The inclination of the guide M' can be adjusted by a screw M'. The mirror K may be mounted on a disc K' which can be rotated by a screw K<2> for initial adjustment. The arrangement can be duplicated to deal with adjustments in two planes at rightangles to each other. In a further form, for single-plane adjustment, the telescope R, Fig. 14, and a weak lens S are mounted, with optical axes parallel, on blocks R', S<1> slidable in guides T', T' perpendicular to the optical axes on a fixed base T, and the blocks are moved at different speeds to maintain the alignment with point x as by providing on them pins R<2>, S<2> engaging slots in a plate U pivoted on a pin U' slidable in a groove U<2> in a plate U<3> angularly adjustable on the base T. Specifications 486,851 and 511,191 are referred to.

Filed: 1974-01-29
Abstract: 1470175 Crane safety devices ODES POLITEKHNICHE INST and ODES ZAVOD TYAZHE KRANOSTROENIA IMENI YANVARS VOSSTANIA 29 Jan 1974 03962/74 Heading B8B [Also in Division G1] To determine the stability of a self-supported object, such as a crane, mounted on supports A 0  incorporating sensors to sense the reaction forces P 1  in the supports, a master contour II (A, B, C, D) is set up which is geometrically similar to the contour defined by the supports A 0  and a guide member such as a pulley 5, 6, 7, 8 is mounted at each vortex A, B, C, D of the master contour II, elements such as a rigid rod or cords 1, 2, 3, 4 being guided by the guide members, one end of each element being connected at a junction O within the master contour II to one end of each other element, and the other end of each element being connected to a respective sensor A 0  in such a way that a force is applied to that element which is proportional to the reaction force P 1  sensed by that sensor and to the length r of that element within the master contour II, the junction O thus taking up a position which corresponds to the projection on the master contour II of the resultant force of the support reactions of the object. As long as the junction O is within master contour II the object is stable. As shown in Fig. 7 the reaction forces P 1  may by sensed by hydraulic piston and cylinder devices 22 (only one shown), the forces being then transmitted via piston and cylinder devices 23 to cords 24. The mid point of each cord 24, between a pulley F and a fixed point E, is attached to a respective cord 1, 2, 3, 4 via a cord 25 and amplifying pulley arrangement 26. This arrangement ensures that the force applied to the elements 1, 2, 3, 4 is proportional to the lengths r 1 , r 2 , r 3 , r 4  of the elements within the master contour II. In an alternative embodiment (Fig. 5, not shown), the elements (9), (10), (11), (12) are each rigid and extend through pivotally mounted guide joints, forces being applied to the pull elements directly by means of hydraulic jacks (13, 14). The apparatus can be used to determine the position of the centre of gravity of an object or objects placed on a transparent platform 61 mounted directly above the master contour II defined by pulleys 5-8, as shown in Figs. 10 and 11, the junction O between cords 65 being coupled to a rotatably-mounted double-acting piston and cylinder device 69-71 such that movement of the junction O and thus of the pistons 70 in cylinder 69 causes rotary movement of a transparent indicator tube 74 and linear movement of a slug of liquid 75 in the tube to indicate the position of the centre of gravity with reference to graduations on the platform 61. Support reactions of the platform 61 are transmitted to the cords 65 by cords 24, the weight of the platform 61 itself being counterbalanced by springs 77.

Abstract: 1,118,805. Track propulsion systems. PEARNE & LACY MACHINE CO. Inc. 26 Jan., 1967 [27 April, 1966], No. 3966/67. Heading B7L. [Also in Divisions B8 and F2] Bricks after being formed are conveyed (see Division B8) on to a Kiln car 14. The latter is moved along step by step through a Kiln (19) (Fig. 1, not shown), in time with the delivery of each row of bricks by a piston and cylinder 73, 72, connected between an indexing carriage 67 and the machine frame. The carriage 67 has dogs 76, 76, spaced a distance apart equal to the length of a Kiln car 14. Each dog is adapted to engage an axle 77 (Fig. 9 of the car). The piston 73 is energized by a switch 84 actuated when a member of the switch drops into one of a series of openings in a control bar 82 carried by the carriage 67. The spacing of the openings corresponds to the intervals of each step of movement of the car 14. Two further switches 86 and 87, similar to the switch 84 but laterally adjacent thereto, cooperate with two further openings in the bar 82 corresponding to the two extremes of movement of the carriage 67. After the car 14 has been conveyed through the Kiln (19), each successive row of bricks is discharged on to an endless conveyer belt leading to a stacking operation (not shown).

Title: Improvements in or relating to lubricating devices
Inventor: EDGE STANLEY HOWARD
IPC: F16N13/16
Filed: 1953-02-12
Abstract: 739,182. Lubricating. CLAYTON DEWANDRE CO., Ltd. Feb. 1, 1954 [Feb. 12, 1953], No. 4008/63. Class 12 (3). A lubricating device of the kind in which a pump plunger is arranged to discharge lubricant through a rotary distributer to each of a ring of delivery conduits in succession, through stepby-step movement of the distributer, is adapted to be actuated by a fluid-pressure or vacuumoperated piston through the medium of a thrusttransmitting member which operates the pump plunger and also operates pawl-and-ratchet means to effect the step-by-step movement of the distributer. As shown, a casing 1 is closed at one end by a detachable cap 2 which is provided with a ring 3 having a circular row of conduits 4. Each conduit communicates under the control of a spring-loaded valve 5 with an outlet 6 leading to a delivery pipe 7. The cap 2 is provided with a bearing 10 for the hub 11 of a rotary distributer, the hub having an axial bore to receive the pump plunger which is in two parts 14, 15 separated by a gap 12. The bore has an inlet port 13 and an outlet port 20 which communicates through a passage 22 in the hub, a passage 23 in a radial delivery arm 24 and a passage in a plug 26 with one of the conduits 4 leading to a delivery pipe 7. When the pump plunger is operated lubricant in the gap 12 is eventually forced along these passages to one of the conduits 4. The size of the gap 12 may be adjusted by means of a cam 28 engaging a flange 24 on the part 15 of the plunger. The part 14 has a cap 45 adapted to be engaged by a roller 42 on a pivoted, bifurcated arm 41 formed integrally with a shaft 39 mounted in bearings 40. The arm 41 is engaged by the rod 36 of a piston 33 which is operated by fluid pressure supplied through a port 35. As the piston reciprocates the shaft 39 -oscillates and by means of a pin 56 projecting from the shaft and a U-shaped slot 54, effects the oscillation of a pawl-carrier 49, the pawl of which co-operates with a ratchet 46 fixed to the distributer. The arrangement is such that during the delivery stroke of the pump plunger the pawl rides over the teeth of the ratchet, but on the return stroke the ratchet wheel is moved one step by the pawl whereby the delivery arm of the distributer registers with the next of the conduits 4. In a modification the axis of the piston which is vacuum-operated is at right angles to the axis of the pump plunger.

A door handle mechanism comprises, when assembled on a door 13, a pair of handles 2, 3, one at each side of the door, mounted on a common bolt or latch operating spindle 1, a rose 11, 23 around the spindle between each handle and the door, and a mounting plate 5 applied to, and secured flat against one side of the door and having the spindle screw-threaded therethrough, the rose 23 at this side of the door being secured to and against the mounting plate but not directly to the door. The mounting plate 5 is fixed to the door by wood screws 7 and has a screw-threaded central aperture into which the spindle 1 is threaded. The spindle is of square section with the screw-threads formed at its corners only, over part of its length. The threaded end is slidably but non-rotatably received in a square recess 27 in the handle 2 and the other end of the spindle is a force-fit in a recess in the handle 3. Each handle has a boss 12 on which respectively the roses 11, 23 are rotatably mounted, the rose 11 for the handle 3 being secured to the door by wood screws 15. The rose 23 for the handle 2 covers the mounting plate 5 and is fixed to it by screws 24 which engage threaded holes in the mounting plate. Each boss 12 also carries a disc 16 which is fixed so as to rotate with the handle and which has cut away portions (not shown) co-operating with stops on the rose (not shown) to limit the rotation of the handle. Each handle has a tension spring 20 housed in a recess to return the handle to its initial position. The mounting plate 5 is provided with a plurality of holes for the screws 7 and 24 so that the handle 2 can be mounted on the door in alternative positions. In use when the handles are rotated the spindle moves slightly transversely of the door due to its threaded engagement with the plate 5 and sufficient play is left in the mounting of the rose 11 in its boss to allow for this.

[Class 36.] In a long cable manufactured in sections provided with temporary lead sheaths, which after the connection together of the sections are stripped off and replaced by a single lead sheath which extends over the whole cable, the stripped cable traverses a drying chamber before passing to the lead press. The Figure shows an arrangement wherein a continuous length of cable C, comprising a number of jointed sections with temporary sheaths, is passed in succession through a stripping machine S, a drying oven DO which may be evacuated or through which dry air may be passed, and a lead press LP. The stripping machine removes the temporary sheathing from the cable which is then coiled a number of times around a drum DR in the drying oven. A continuous sheathing is applied to the cable by the lead press LP. To prevent the cable from absorbing moisture as it leaves the drying oven, it is passed through a tube T connecting the oven to the lead press and preferably flexible and heated. A similar tube may connect the oven to the stripping machine, or the stripping machine may be disposed at the end of the oven. To increase the time of drying the joints between the sections of cable, the recharging of the lead press may take place when a joint is in the oven. The drum DR may be freely mounted or may be driven in synchronism with the stripping machine and lead press. In a modified arrangement the drying oven is in the form of a tube having a number of drums or guide rollers and is heated either by hot air or by electric heating elements.

Abstract: 404,475. Locking brake mechanism. ZAHNRADFABRIK FRIEDRICHSHAFEN AKT.-GES., Friedrichshafen-on-Bodensee, Germany. Feb. 13, 1933, No. 4422. Convention date, March 4, 1932. [Class 80 (iii).] A device for locking a brake-operating linkage in adjusted position in which a clamping element frictionally engages a stationary member under the stress in the linkage and is disengaged by movement of the operating lever in either direction, comprises a lever d, which, under the stress in the link b connected to the brakes, grips a stationary rod c to hold the link in adjusted position. When the hand lever a and a member e connected thereto and slidable on the rod, are moved to the right, the lever d is engaged by a projection e<1> on the member e, thereby releasing the lever d and moving the rod b to the right to apply the brakes. When the lever a and member e are moved to the left the lever d is also disengaged and the link b moves to the left to release the brakes. To avoid the tendency of the lever d and link b to return suddenly to the brakes-released position when the lever is disengaged, a spring g is provided on the member e to urge the lever to the clamping position.
