Abstract: 868,959. Centrifugal casting machines; mould materials. COMPAGNIE DE PONT-AMOUSSON. April 21, 1959 [April 23, 1958], No. 13518/59. Class 83 (1). A process for centrifugally casting a tubular, cast or spheroidal graphite, iron member comprises rotating a metal mould 4 at casting speed or higher, applying to the walls of the mould a thin layer 19 of a fine, dry silica flour, and then casting the member. The mould 4 is surrounded by a water jacket 5 and is rotated by a motor 6 on a carriage 1 traversed by a ram 10. Dry silica flour is blown from a container 13 along a pipe 16 on to the mould face. The flour may consist of sediments of diatomaceous earth, metal oxides and lime, and its grains have an elongated form having a maximum diameter between 0.03 and 0.09 of a millimetre. Instead of blowing-on the coating, it may be tipped from a trough.

Title: Profiling roller for the rolling of a profile in the grinding wheel of a thread grinding machine
IPC: B24B53/07
Filed: 1976-04-06
Abstract: The roller has, in the centre, a finish-rolling rib which corresponds to the flank angle, the core radius, the pitch-circle radius and the rib height of the thread to be produced. Pre-rolling ribs with decreasing rib height are arranged symmetrically towards the two ends. The core radius on the pre-rolling ribs increases progressively at the ends of the roller (R3 > R2 > R1) and the flank angle decreases progressively ( alpha 3 <  alpha 2 <  alpha 1). Relative to the pitch-circle radius of the finish-rolling rib, the pitch-circle radius (2, 3) of each pre-rolling rib is selected to be progressively greater than an amount (z1, z2) such that the distance (y1, y2), measured from the cutting point of the flank of an inner rolling rib with its associated pitch circle, at right angles to the corresponding flank of the next rolling rib arranged towards the rolling end, is essentially equal to the difference (x1, x2) between the rib heights of neighbouring rolling ribs. This roller makes it possible to give a grinding wheel such a profile that said wheel can grind taps by longitudinal feed, industrially, from both sides. <IMAGE>

Abstract: 567,638. Electric signalling systems. GENERAL ELECTRIC CO., Ltd., and FIELD, R. W. G. Oct. 29, 1941, No. 13902. [Class 40 (i)] The position of apparatus, such as an electric meter or water-level indicator, having 2<n> possible positions is transmitted to a remote indicator by a succession of n signals, of which the first identifies the half of the scale in which the pointer stands, the second identifies the quarter, and so on. The meter VL is of the type disclosed in Specification 433,569, [Group XXXVII], and the operation of a clutch magnet CL brings the pointer P into connection with one of 32 contacts, whereupon a rotary switch SM takes up a corresponding position. This switch has 5 wipers of which the contacts are connected in multiple to five pairs of wires IT 1-5, IC 1-5 for the transmission of the signals, which are sent in succession to the distant station, for example, in the manner described in Specification 409,472. The indicating switch MR is of the kind disclosed in Specification 432,606, [Group XXXVII], which rotates in either direction under control of magnets MRA, MRB. The signals are received over five pairs of wires OR 1-5, CR 1-5 and each operates relay LX or UX, while relays HA-HE are operative in succession to connect up the 5 wipers of the switch MR, the contacts of which are multipled together like those of the wipers of SM. Thus the switch moves, if necessary, to the apporpriate half of its bank, then to the appropriate quarter, and so on, a return signal being sent after each setting to initiate the next signal.
