Title: Improvements in apparatus for braking motor-vehicles
IPC: B60T11/04
Filed: 1923-05-04
Abstract: 207,780. Fortini, A. Dec. 4, 1922, [Convention date]. Addition to 196,578, [Class 103 (i), Brakes &c.]. Brakes, arrangement and disposition of, and braking.- Improvements on the invention described in the parent Specification and on that described in Specification 197,294 consist (1) in mounting the disc e which carries the pivot of the cam and of the brake blocks of the one brake, so that it is free to rotate for effecting the application of the other brake and in dispensing with the springs by which the parts are returned, according to the parent Specification, to the normal position; (2) in means. whereby the force applied to the pull rod o which operates the second brake is in the same direction irrespective of the direction in which the wheels and disc e are moving. In Fig. 4 this is effected by connecting the rod o to a lever 5 pivoted at 4 upon the fixed axle casing and by providing two lugs 6, 7 on the disc e one or other of which presses upon the respective arms of thelever 5 according to the direction in which the disc e tends to turn. In another arrangement a lever corresponding to the lever 5 is disposed parallel to the plane of the disc e ; (3) in the provision of a spring in the connections to the second brake so as to limit the force applied thereto. Fig. 8 shows a leaf spring 14 forming a yielding arm on a cross-shaft q-w of the arrangement described in the Specification 197,294 by which the connecting rod t-z connected to the one brake actuates the other.

[Also in Group XXIX] The torque on a torque transmitting flexible element 1 is measured by epicyclic gearing comprising a pair of coaxial sun pinions 8, 9, one pinion 8 rotating with the element 1 and the other 9 rotating with a shaft 4 lying within the shaft 1 and keyed thereto at the end remote from the pinions, the pinion 8 having a slightly greater pitch circle diameter than the pinion 9, and, as shown, two pairs of coaxial planet pinions 11, 12 fixed for rotation together in mesh with their respective sun pinions and mountedcoaxially on shafts 13 carried by a rotary spider constituted by a pair of rings 14, 15, indicating or signalling means responsive to rotation of the spider being indicative of the torque transmitted. In the embodiment shown a valve sleeve 17 having a peripheral port 35, Fig. 2, is fixed for rotation with the spider, the port 35 co-operating with a port 34 on a valve disc 32 connected for rotation with the shaft 4 so that on reversal of torque the pressure in a chamber 40 is relieved via passages 30, 31, 33 and ports 34, 35 thereby operating a control switch 44 via a pressure membrane 41. The mechanism may be designed to operate on the attaining of a torque of selected magnitude.

Class 69 (1) A reinforced concrete tank has pre-stressed side walls supported on an annular foundation and the base of the tank is formed of sheet metal the peripheral margin of which is bonded, keyed or otherwise interlocked in a leakproof manner with the side walls or the foundation. The base may have an upwardly domed surface resting on the ground and may be of such thickness that it assumes a downwardly domed shape when the tank is filled to a predetermined level. In one form, Fig. 1, the peripheral margin of the upwardly domed steel plate floor 2 is embedded into the annular foundation 1 and the pre-stressed side walls 9 are mounted on the foundation. The floor margin may have holes 4, Fig. 2, to key it into place, and the margin also may be cut radially as at 5 and the tongues so formed twisted to assist in keying. The floor may be built up of several sheets welded, riveted or otherwise joined together. In another form, Fig. 4, the flat floor 11 of steel plate is formed with an upwardly extending flange 12, which rests on the annular foundation 1 and wall 9 is then cast so that the flange extends into it. Alternatively, the wall may be cast so that its base is located within he flange. The pre-stressing of the walls may be effected by hooping reinforcing wires therearound and tensioning the wires as described in Specification 691,003. In addition, vertical pre-stressing wires may be located in grooves on the outside of the walls, and covered by cement after tensioning.

Filed: 1957-04-17
Abstract: 819,942. Consolidating metal. STERNBERG, J. DE. April 17, 1957, No. 12623/57. Class 83 (4), A metal body 2, particularly an ingot of iron or steel alloy for subsequent rolling or drawing, is compacted within a receiver 1 by first compressing the body beyond its elastic limit by means of a gas-free hydraulic pressure medium and then further compressing it by the thermal expansion of a liquid acting on the pressure medium. After insertion of the ingot into the receiver, the end is closed by a plug 3 and a valve 4 is opened by means of a piston 5, Fig. 2 (not shown) to allow a pressure medium consisting of a plastic mass of graphite and a molybdenum sulphide to be forced by a piston at a pressure of about 30,000 kg. per square cm. through bores 6, 7 and into receiver 1. Bore 7 also communicates through bores 17 with longitudinal bores 16 in an annular member 11 insulated by sleeves 19, 20. The bores 16 contain mercury. After the first compression, valve 4 is closed and the mercury is then heated to about 200‹ C. by an electric heater 28 to further pressurize the hydraulic medium to about 300,000 kg. per square cm. The mercury may be subsequently cooled by a coolant circulated through coils 29. The valve 4 acts as a safety device.
