Title: Improvements in or relating to a measuring machine and method of measuring a workpiece
IPC: G01B7/02
Filed: 1947-05-22
Abstract: 652,868. Gauging linear dimensions; electrical. BROWN & SHARPE MFG. CO. May 22, 1947, No. 13772. Convention date, June 20, 1946. [Class 40 (i)] [Also in Group XIX] In a machine for measuring linear dimensions comprising a tailstock 24 and headstock 22, Figs. 1 and 2 (see Group XIX), the axially movable headstock carries an axially adjustable spindle 28 for fine measurements, e.g. up to 0.00001 inches, the position of the spindle relative to the headstock being measured by bonded electrical strain sensitive gauges mounted on a spring plate 108 connected between the spindle and an element 106 which moves with the headstock. Similar gauges are mounted on a plate 36 for indicating the position of the tailstock spindle 30. As shown in Fig. 8, the gauges on plates 36, 108 are connected in Wheatstone bridge circuits R31-4, R131-4 respectively. The tailstock circuit is balanced by a potentiometer 265 adjusted by a knob 266, Fig. 1, on a panel 268. The headstock circuit is balanced by a potentiometer 270 whose scale is varied by a potentiometer 271. The potentiometer 270 is adjusted by a knob 272 on the panel 268 which also rotates a dial 274 on which a scale is so calibrated, that on movement of the potentiometer 270 to eliminate the unbalance in the headstock circuit due to movement of the spindle 28 relative to the element 106, the dial gives an exact indication of the distance moved by the spindle (e.g. in units of 0.00002 inches). The circuits are closed one at a time by a doublethrow switch 278 controlled by a knob 279 on the panel 268 which also connects the circuits to a sensitivity - controlling potentiometer R3 controlled by a knob 260 on a casing 254, Fig. 1. This casing contains an amplifier for the unbalance voltage fed to potentiometer R3 and an oscillator which supplies current to the Wheatstone bridge circuits through a transformer T2, 1 and also supplies current to a transformer T2, 2. The amplified unbalance voltage is fed to a transformer T3, 1, and the outputs of transformers T3, 1 and T2, 2 are fed through a rectifier ring RX to a meter 255, which then indicates the direction of unbalance. In operation, the dial potentiometer 270 is set to zero and the meter pointer is then brought to zero for the headstock circuit by movement of the spindle 28. After subsequent adjustment of the machine to register the dimension of the work-piece to the largest complete thousandth of an inch (see Group XIX), the spindle 28 is adjusted to remove any strain on the plate 36. The headstock circuit is switched in and the potentiometer 270 rotated until the pointer of the meter 256 is again returned to zero when the dial will indicate the distance moved by the spindle 28 from its zero position and thus the remaining fraction of the dimension of the work-piece. The machine may be used for external or internal gauging.

Abstract: 849,204. Burners. STEWART-WARNER CORPORATION. May 2, 1958, No. 14146/58. Class 75(1), [Also in Group XIII] An air heater (see Group XIII) in which air is heated in a heat exchanger by combustion gases from a burner unit, comprises a combustion chamber 50 and a resiliently mounted readily removable burner arranged at the end of a cylindrical member 28 (not shown) of the air heater. Fuel is supplied to the burner nozzle 62 by way of a passage 94 and a magnetically actuated poppet valve 88. A safety switch (not shown) on the heat exchanger operates to cut off the fuel supply if the heat exchanger becomes too hot. The burner is housed in a cup member 70 defining a space 66 to which combustion air is admitted through one of two openings formed through hollow bosses 96, 98, Fig. 2, on the member 70. The other boss opening is partially closed by a plate 100 in which is a small hole 102 the effect of which is said to prevent noisy operation of the burner. The combustion air passes from the space 66 through louvres 64 which effect swirling of the air and into the combustion chamber 50 by way of holes 58 (see Fig. 5) in the side wall thereof. Turbulence within the burner is effected by means of a narrow metal strip 67 (see Fig. 5) which extends across the mouth of the combustion chamber. Rubber tubular members 104, 106, Fig. 2, are fitted over the bosses 96, 98 and engage the inner surface of the heat exchanger casing 10 providing a seal for the combustion air stream and also a resilient support for the louvres.

Title: Method of and apparatus for testing magnetizable objects
IPC: G01N27/80
Filed: 1923-06-05
Abstract: 223,268. Marks, E. C. R., (Burrows Magnetic Equipment Corporation). June 5, 1923. Magnetic tests and measurements.-The hardness, tensile strength, homogeneity, &c. of magnetizable objects are deduced from their magnetic hysteresis, which is determined by subjecting the object to the action of a relatively rotating magnetic field and measuring the resulting torque. In the apparatus shown, a three-phase magnet has three cores formed from U-shaped laminations, each of which forms part of two cores and the connecting yoke. The yoke portions are bolted between radial flanges 2<a> formed on a non-magnetic base 2, the upper ends of the cores being fitted into openings in a non-magnetic plate 3 spaced from the base 2 by parts 2<c>. The cores are wound with coils 1<c>. The pole-pieces If consist of laminations bolted between radial flanges 4a formed on a non-magnetic top plate 4, which is removably secured to the posts 2<c> by bolts 4<e> passing thorugh holes in studs 4<c> attached to the plate 4. The article to be tested, for example a ball race R, is carried on a support 5d so as to be situated in the rotating field between the pole-pieces 1f. The support 5d is mounted on a spindle 5<a> controlled by an adjustable spring 6 carries a pointer 5<c> moving over a scale 7 beneath a glasscovered opening in the plate 4. In operation, a standard ball race is placed on the support 5d and the spring 6 adjusted until the pointer 5<c> stands at zero. A ball race to be tested is then substituted for the standard and the deflection noted. A rotating permanent or electromagnet may be employed in place of the polyphase magnetic field, or the object may be rotated in a stationary field. Reference has been directed by the Comptroller to Specification 2308/95.

Abstract: 552,933. Hydraulic presses; valves. SCHERMULY, C. D., SCHERMULY, A. J., and SCHERMULY, C. Nov. 19, 1941, No. 14862. [Classes 69 (ii) and 135] [Also in Group XXI] In an hydraulic press used in making rockets, the ram 3 is raised in jerks to tamp the powder ; when the powder has been compressed to a certain extent, the pressure on the ram is released automatically or by an operator, the drift is raised, more powder is put into the casing, the tamping tool is changed, and the process is repeated. Fluid passes from a reservoir 15, Fig. 1, through pump 14, overload valve 12, manuallyoperated valve 11 and pipe 10 to the press 2. An overflow pipe 16 connects the valves 11 and 12 with the reservoir. The pump 14 is operated by an electric motor 17, and comprises a long small-diameter piston 20, Fig. 2, an inlet valve 27 and an outlet valve 28. The valve 12 is adjustable to byepass the fluid back to the reservoir when a given pressure (indicated by a gauge 9) is reached in the pipe 10. The valve 11 comprises an inlet 36, Fig. 5, an outlet 37 and a byepass outlet 38 which is normally shut off from the fluid flow by a plunger 33 which is held depressed by the operator by means of a lever 44. The pressure may be released by the operator at any time before the pressure is automatically released by the valve 12.
