IPC: B21B31/18
Filed: 1963-09-09
Abstract: 1,103,102. Rolling. DAVY & UNITED ENGINEERING CO. Ltd. 9 Sept., 1964 [9 Sept., 1963], No. 35492/63. Heading B3M. A rod-rolling mill comprises a pair of horizontal grooved rolls, each of which is mounted in chocks which are axially and vertically adjustable relative to the mill housings. The roll necks 14 of each roll are each carried in a tapered sleeve 16, the sleeve being supported in a bush 18 of a chock 20. Axial thrust bearings 26 are situated between the sleeve and chock. An extension 42 of the chock has screwed into it at 48 a rod 46 which extends outwardly through a threaded bore 50 in a yoke 52. The yoke is axially fixed relative to the mill housings 22 by wings 58 so that rotation of hand wheels 54 causes axial adjustment of the chock and roll 12. The wings are held in contact with wearing strips 60 by a clamp 62, vertical movement of the yoke thus being permitted with similar adjustment of the roll. The wings can be fitted with adjustable studs, Fig. 3, and the clamp can be provided with an adjustable spacer 70 and a resilient arm 66B.

Title: Load indicating device for cranes and the like
IPC: G01G19/14
Filed: 1931-12-23
Abstract: 394,681. Weighing-apparatus. JAMES, R. T., HAUSSER, P. C. G., Bush House, Aldwych, and AITKEN, R. L., Windsor House, Victoria Street, both in London. Dec. 23, 1931, Nos. 35493/31 and 6971/32. [Class 143.] The load on a crane, derrick, or like lifting- apparatus is indicated by means of a lever moving about a stationary pivot and influenced differentially by the load-stress through the medium of a cable, flexible sling, or equivalent means, in opposition to a spring or the like. The load may be recorded. As shown in Fig. 1, the stress in a tension member 21, which may be in the jib-tie of a crane, is transmitted by a lever 19, 16, sheave 14 and cable 14a to a lever 10 which is restrained by a spring 23. The cable 14a is secured to sectors of different radii Y<1> Y<2> on opposite sides of the pivot of the lever 10 so that the two branches of the cable exert different turning moments on the lever. In modifications, Figs. 2 and 3 (not shown), the cable is secured to two points on the lever 10 at different distances on opposite sides of the pivot, or it is replaced by a linkage connected similarly with the lever. The lever 10 may actuate a pointer directly or through gearing, and the load may be recorded or the pointer may close a circuit to give an audible or visible signal or both. As applied to a crane with variable outreach, the device is combined with means influenced by the outreach to form a safe-load indicating device.

Filed: 1928-12-04
Abstract: 326,146. Freedman, P. Dec. 4, 1928. Vacuum tubes. - A thermionic valve is provided with a screen consisting of a refractory openwork structure, such as a narrow ring or rings, or a continuous member having gaps, perforations &c., which is so shaped and disposed as to shield the electrode leads and supports, but not the electrodes, from the high-frequency field of the induction furnace during the process of heating the metallic parts within the valve, so that the heating effect on the leads, the supports, and the vitreous stem is small. The screen may have its ends connected electrically and may serve as a support for magnesium or other getter. In one example a ring 8, Fig. 2, of high resistance metal such as nickel-chrome is carried by supports 9 which are tied to a stem 4 by wires 10. A helical screen (Fig. 1, not shown) may have its ends welded to the anode.

[Also in Groups XXI and XXIX] In well-drilling apparatus having an hydraulic turbine located near the lower end of a drill string, a channel is provided by-passing the turbine and having valve means for controlling the flow of fluid through the channel to keep the turbine speed within restricted limits. In Fig. 1, the turbine casing 2 is connected to the drill string 8 and its rotor shaft 3, which is hollow, is connected to a bit 7. Fluid circulated down the drill string 8 passes through the turbine blading 4, through ports 18 and then through the bit 7. Fluid on the inlet side of the turbine communicates through ports 19 with the inside of the rotor shaft 3 but is prevented from by-passing blading 4 by a spring-pressed valve 16 which opens when the pressure difference between the turbine inlet and outlet reaches a predetermined value. The valve may be a sleeve valve and may communicate with the outside of the turbine casing 2. In another embodiment, Fig. 6, a governor 24 opens a valve 25, in relation to the turbine speed, when fluid from the inlet side of the turbine acts on a servo piston 22 which depresses a valve head 16, urged towards its seat by a spring 20, and allows fluid to bypass the blading 4.

Abstract: 905,810. Indicating liquid levels. AUTOLEVEL Ltd. Jan. 17, 1961 [Oct. 27, 1959], No. 36466/59. Class 123 (1). A low level warning device, for example for the sump of a motor vehicle, comprises a hollow probe 1 having an opening 2 at a point corresponding to the said low level, connected via a flexible tube 3 to a collapsible bulb 4 made, for example, of rubber, and disposed within a rigid container 5 secured to the dashboard 7 of the vehicle. A push-button 8 is permanently fastened to the collapsible end of the bulb and passes through the end wall of the container 5. The stem 8a of the bush-button, which is not visible when the button is depressed, is coloured red, whilst the tip is, for example, black. When the oil level is to be checked the button 8 is depressed, whereupon air is driven out through the opening 2. If the oil level is below this opening, the button when released immediately re-emerges, exposing the red stem 8a to serve as a warning of " low " level. If the oil level is above the opening, the red portion of the button will remain obscured. In a modification, Fig. 2, a green indicator 9 is movable inside a transparent air-tight sleeve 10 which is connected to the probe 1 via a tube 11. The indicator is connected to the collapsible wall by a rod 13 passing through the interior of the bulb. Deflation of the bulb is effected by pressure upon a button 12 which causes the green indicator to pass into the sleeve 10, and to remain there after removal of the pressure if the oil is above the " low " level. The movement of the bulb in both embodiments can be used to close electrical contacts to illuminate a lamp to give the desired indication of oil level. Specification 791,242 is referred to.
