Title: Indexing mechanism for machine tools
IPC: B23Q16/02
Filed: 1953-03-30
Abstract: 725,191. Machine-tool details. HOERN, J. H. March 30, 1953, No. 8793/53. Class 83 (3). An indexing mechanism for a machine tool comprises a carrier 5 with spaced notches 10 in its circumference, a detent 27 to engage the notches but of substantially less width than the notches, and a locking wedge W to co-operate with an inclined wall 17 in each notch for clamping the detent against an opposite wall 16 in the notch. As applied to indexing the work-carrier 5 of a boring and turning machine having four work stations 8, the carrier may be turned in steps each of slightly more than 90 degrees, as by a Geneva mechanism, to allow the detent 27 to enter the indexing recess 15 provided in an insert 12 for each notch 10 without engaging the walls 16, 17 of the recess. The detent is formed on a lever 22 pressed towards the carrier by a spring 34 and having a slot 28 to receive the wedge W. A pin 33 on the wedge slides in a slot 32 in the lever and holds the latter clear of the carrier against a spring 22 until the wedge is moved towards the carrier, as by a doubleacting fluid-operated piston in a cylinder pivoting at 40. The wedge follows the detent into the recess and, upon engaging the wall 17, turns the carrier to clamp the wall 16 of the insert 12 against the detent. The notches 10 have walls 11, Fig. 3, which are inclined to the axis of the carrier and engage similar walls 14 on the inserts 12 so that the recesses 15 may be adjusted within the notches, the inserts being secured by screws 20 engaging slots in the inserts.

Title: Improved method and apparatus for atomizing fuels
IPC: F23C99/00
Filed: 1934-03-21
Abstract: 440,717. Spray burners. LUCICH, G., 518, Chiadino S. Luigi, Trieste, Italy. March 21, 1934, No. 8888. [Class 75 (i)] In the atomization of heavy oil prior'to combustion, the initial mixture formed by air-introduced under suction or pressure as at 5-and sprayed oil-as from nozzles 8, 9-is cooled to such extent that, prior to final mixture, the whole of the fuel content takes the form of minute droplets. The further mixture or atomization is effected by passage of the droplets with the accompanying air through fan wheels 24, 25 and strainers 26, 29. The cooling results from the expansion of the mixture due to enlargement of the cross section of the atomizer after the point of entry of the fuel. This cooling may be assisted, or if necessary neutralized, by the circulation of fluid of appropriate temperature in the hollow walls 11. The fans may rotate in opposite directions or the second fan may be stationary. The air inlet nozzle 5 is of double taper and interchangeable nozzles to suit different loads may be provided. A rotary hit-and-miss valve 17, 18 with radial slots serves as a throttle for the mixture. The actual burner nozzle may have whirl ribs or, as shown, straight steadying ribs 27. A conical shield 3 with apertures surrounds the burner nozzle. Reference is made, with a view to differentiation of the invention, to the four Specifications noted below. Reference has been directed by the Comptroller to Specificatiom 14486/98, 21983/07, (both in Class 7], 2796/13, and 9802/13, [both in Class 7 (ii)].

Title: Improvements in or relating to methods of permanently elongating strip

IPC: B21D25/00
Filed: 1969-02-21
Abstract: 1,262,577. Stretching. HERR EQUIPMENT CORP. 21 Feb., 1969 [28 Feb., 1968], No. 9555/69. Heading B3E. A method of permanently elongating metal strip comprises applying tension to the strip and constraining the tensioned strip to at least one bend and at least one bend reversal such that yielding occurs on at least one side of the strip and such that on the first and all subsequent bend reversals the slope of that portion of the stress distribution curve for tensile and compressive stresses less than the tensile or compressive yield stress respectively reflects both the immediate previous bending strain and the existing bending strain reversal but is otherwise independent of bending strain history. Equations are given which show the relation between elongation strain and the applied tensile force for successive bends of specified radii on a strip of specified thickness and tensile yield strain; the equations taking into account yielding at one or both sides of the strip at one or both of two successive bends. Examples of the application of these equations to a strip are given in which the values for elongation strain and tensile force were measured using the apparatus shown in Fig. 8 in which tension is applied to a strip 11 by an hydraulic cylinder 12 and measured by gauges 13 and 14 at each end of the strip. Bending strains are applied by rolls 17, 18 and 19 carried on a cart 20 running on a smooth track 21. A gauge length (50 inches) is marked on the strip, tension applied and the strip elongated by moving the cart with its rolls along the strip. The elongations obtained by measuring the distance between the gauge marks after stretching are in close agreement with those obtained from the equations given.
