Title: Improvements in or relating to means for attaching on each side of a vehicle chassisor body a frame carrying an endless driving track
IPC: B62D55/084
Filed: 1948-10-15
Abstract: 656,269. Endless track vehicles. TAPP, E. T. J., and DAVEY, J. Oct. 15, 1948, No. 26919. [Class 79 (i)] In an endless track vehicle of the kind having track frames which are pivoted to the vehicle about transverse pivots close to an axle carrying sprockets for driving the tracks, and are connected to the vehicle by a transverse spring and a linkage system constraining the frames to move in an up and down direction, the linkage system comprises two links mounted independently of one another on opposite sides of the vehicle and each link has its opposite ends pivotally connected to the vehicle and its frame so as to swing about fore and aft axes. As shown the invention is applied to a tractor having an engine and gear casing 10 forming the tractor frame. Each endless track is driven by the sprocket 13 mounted on the axle 12 and on the underside of each end of the axle casing is mounted a pin 15 which engages a resiliently mounted bush 16 carried by the track frame. The track frame is formed of channel shaped members 18, 19 and carries idler roller spindles 26, a spring urged jockey pulley 27 and a spring box 23. The spring in the box 23 operates through a rod 24 and an arm 25 on bearings 21 of a pulley 20, the bearings being slidable along guideways 22 against a stop. Secured against faces 28 of the engine casing 10 are the limbs of a yoke piece 29, the base of which has a bracket 46 for securing in position the leaf spring 30. Some of the blade ends of the spring 30 on each side form an eye for receiving a pivot pin 33 carried in a box-like carrier 34 which is secured by flanges 35, 36 to the frame members 18, 19. Extending from each limb of the yoke 29 is an arm 37 having an eye 38 for receiving a pivot bolt 39 carried by the U-shaped link 40. The other end of the link 40 receives a pivot pin 42 engaging a lug 43 extending upwardly from the spring box 23. According to the Provisional Specification the pin 42 can be carried by two lugs or the like mounted on the top of the track frame. The axes of the bolt 39 and pin 42 are so arranged that they pass through the axis of the pin 15 constraining the track frame to move in an up-and-down direction. By suitable selection of the length of the link 40 and spring 30 the track can be made to rock on its bottom supporting rollers without lateral shift. The pivots may be provided with resilient bushes.

Title: Correcting ocular defects
IPC: A61B3/04
Filed: 1935-09-30
Abstract: 461,761. Spectacle lenses. DARTMOUTH COLLEGE, TRUSTEES OF. Sept. 30, 1935, No. 26970. Convention date, Oct. 26, 1934. Addition to 412,081. [Class 97 (i)] The invention is a development of that described in the parent Specification wherein means are disclosed for correcting visual defects due to differences between the sizes or shapes of the images of a given object perceived by the two eyes of the observer. This invention is concerned with the correction of visual defects which result in the magnification of the image being irregular along any meridian, i.e. the image is distorted in such a meridian. To correct this defect a spectacle lens or lens system is provided which produces distortion neutralizing the visual distortion, without producing any deviation of the line of vision. The invention also provides, for the purpose of correcting phorias, a lens or lens system which produces deviation of the line of vision without any distortion of the image. A lens for the latter purpose consists of a " meniscus prism " 6, the curvatures of the surfaces 7, 8 of which in the horizontal plane are such as to compensate for the distortion which would be produced by a prism having plane surfaces. The curvature of the surfaces 7, 8 produces a change in the size of the image in the horizontal meridian and, to compensate for this, the surfaces are also curved vertically, as shown in Fig. 11, the curvature being such that the change of size of the image is uniform in all meridians. To compensate for this change of size there is combined with the prism 6 a lens 9 of the kind described in Specification 412,081 which effects a change of magnification without any change of focus. If the eye has to be corrected for refractive error, such correction may be effected by modifying the lens 9 as described. in the said prior Specification. To effect distortion without deviating the line of vision, there may be combined with the prism 6 a second prism 109, Fig. 20, having plane faces and producing deviation equal and opposite to that of the prism 6, and also producing distortion. A size-changing lens 113, as above described, which may be modified to compensate for refractive errors, is combined with the prisms. Instead of using two prisms of the form shown in Fig. 20, two meniscus prisms having their concave surfaces facing each other and their bases oppositely directed, may be employed. Constructional data for the prisms are given. Specification 431,705 also is referred to.

Abstract: 895,246. Refrigerating. COMPAGNIE INDUSTRIELLE DES PROCEDES RAOUL PICTET, and HOUPLAIN, M. Aug. 21, 1958 [Sept. 4, 1957], No. 26973/58. Class 29. In a heat transfer system comprising a sealed container containing a gas space E and a body of liquid, a cold source being located in the upper part and a heat source in the lower part, the liquid L2 boils in contact with the heat source and the vapour condenses on the cold source, a different liquid L1 also freezing on the cold source to form a cold accumulator. As shown in Fig. 1, an evaporator coil 2 is immersed in a freezable liquid L1 and a heating coil 3 in a denser volatile immiscible liquid L2 the vapours of which bubble through liquid L1 to gas space E, condense on the surface of liquid L1 and fall therethrough back to the lower body of liquid. In a modified form, coil 3 is omitted and the volatile liquid is led through a coil in the space to be cooled, the resulting vapour being fed to the gas space by an external conduit. As shown in Fig. 4, coils 2, 3 are located in separate containers 9, 10 joined by vapour and liquid conduits 11, 12. As shown in Figs. 1 and 4 formation of ice around coil 2 raises the liquid level Y . . . Y until contacts 6, 7 are bridged, this de-energizing the refrigerating system supplying coil 2. Alternatively resistance wires normally in the gas and liquid spaces and connected in a bridge circuit effect the control; or a float operated switch may be used. An inert gas may be added to space E to raise the boiling temperature. Liquids L1, L2 may be water or an aqueous or eutectic solution and dichloro-tetrafluoroethane respectively.

Title: Improvements in earth leakage protective systems
IPC: H02H3/16
Filed: 1949-10-26
Abstract: 665,576. Protective cut-out arrangements. BROOKE, W., and BALDWIN, H. T. Oct. 26, 1949. No. 27463/49. Class 38 (v). A remote control protective system for polyphase motors and other apparatus has a control circuit into which under fault conditions a potential is injected in opposition to a relay operating potential, so as to cause the de-energization of the relay, the injection potential being maintained so long as the fault persists to prevent the reclosure of the contactor controlled by the relay. In Fig. 1 a motor M is supplied from lines L1 ... L3 of a supply system having an earthed neutral, when the closing coil D of the contactor C is energized on the closure of the relay contacts H1, H2. The operating coil H4 of the relay H is fully energized so as to close the contacts H1, H2 when a three position switch K in the pilot and earth circuit 5, 6 is moved to a "starting" position K2, the current in this control circuit being subjected to half-wave rectification by a rectifier N. The switch K is then moved into its "run" position K3 to insert a resistance O into the control circuit, so as to reduce the excitation of the relay coil H4 to a level sufficient to maintain the relay contacts closed, but insufficient to reclose them should they have been opened by a fault condition. In the event of an earth fault, as indicated at Z, the "out-of-balance" current induced in the secondary winding Y4 of a core-balance transformer Y is rectified by a rectifier S and applied to an adjustable resistance L, so as to set up across the resistance L a D.C. potential in opposition to the D.C. operating potential applied by transformer secondary winding G2 and the rectifier N to the relay coil H4. This causes the de-energization of the relay H and the opening of the contactor C. When the contactor opens, it connects at C4 the neutral point Q of an inductance P to the centre tap 12 of a further transformer secondary winding G3 so that current flows from the winding G3 through the inductance P, conductor 3, fault Z, earth, earth continuity conductor 6, resistance L and rectifiers U, V. This current maintains a D.C. potential across resistance L in opposition to the control potential so long as the fault Z persists, and the relay H remains de-energized. To re-start the motor it is necessary to remove the fault and move the switch K into the "start" position K2, the switch then being moved back to its "run" position K3. In a modification, Fig. 2 (not shown), in which the motor is supplied from a supply system having an unearthed neutral, a transformer connected between the artificial neutral point Q of the inductance P and earth is effective to apply the opposing potential across resistance L on the occurrence of an earth fault. Specifications 605,927, 605,932 and 636,720 are referred to.
