Title: Non-contacting method of measuring strain
IPC: G01B11/16
Filed: 1970-01-16
Abstract: 1,242,204. Strain gauge. BENDIX CORP. Jan.16, 1970 [Jan.24, 1969], No. 2251/70. Heading G1M. [Also in Divisions G2 and H1] A non-contacting method for measuring strain in a workpiece 34 comprises directing interfering beams 28, 30 from a laser source 12 against a surface 32 on the workpiece 34 so as to thermally engrave a diffraction grating thereon and illuminating the grating with a beam of coherent light 46 so that an interference pattern of the light diffracted from said grating may be observed, measuring a characteristic of light from said grating, subjecting said workpiece to stress to produce a strain and measuring the change in said characteristic to determine the amount of strain produced by said stress in the workpiece. As described a beam of light 14 from a giant pulse laser 12 is directed through lens 16 to prism 18 where the beam is split into two divergent beams 20, 22. These beams are reflected from dielectric reflecting surfaces 24, 26 so positioned that the reflected beams 28, 30 meet at surface 32 of workpiece 34 and interfere so that the surface at regions of intense light evaporates to leave a diffraction grating Fig. 2 (not shown). The giant pulse laser is replaced by a continuous wave laser in the same position 42, Fig. 3 to illuminate the diffraction grating with a beam 46 of coherent light which is reflected through lens 48 to a translucent screen 50. At the screen the diffraction pattern is observed, points of light 52, 54, 56, Fig.4 from a plane surface 32 and a more complex pattern from a contoured surface 32. Movement or changes in intensity of these points may be measured indicating the strain in the workpiece 34. If the workpiece has a cylindrical surface (62) Fig. 5 (not shown) a cylindrical lens (64) is interposed in front of the workpiece to alter the wave fronts to match the configuration of the surface of the workpiece.

Abstract: 489,555. Automatic - feed weighers; specific gravity estimating apparatus. HENNEFER MASCHINENFABRIK C. REUTHER & REISERT GES. Jan. 28,1937, No. 2518. Convention date, Feb. 20, 1936. [Class 143] [Also in Group XX] An automatic weighing-apparatus provided with means for determining the mean specific gravity of the materials to be weighed is characterized in that in addition to a known continuously operating automatic main weighing-apparatus, auxiliary weighing-apparatus is provided which functions automatically and independently of the main apparatus and is connected to the main apparatus in such a manner that after the main apparatus has been discharged one or more times, the auxiliary apparatus is automatically brought into operation by samples of material received from a measuring vessel controlled by the main apparatus, and the weight of the samples is automatically registered on a known counter. The feed valve 2 of the main weighing-apparatus is shown in the open position. When the feed valve closes, a measuring vessel 4 receiving grain from the supply shoot 6 is rotated by a connection 30, into the position shown by broken lines so as to discharge its contents through a tube 9 into an auxiliary scale pan 10 supported on a pendulous lever 12. After a predetermined number of repetitions of these operations, a ratchet and pawl device 18, 18<1 >operated by the feed valve 2 closes the circuit of an electromagnet 20 to release the catch 10<1> of the discharge gate and discharge the contents of the scale pan. A pointer 13 indicates the weight accumulated in the scale pan, and a toothed segment 15 connected to the pendulous lever actuates a counter 16 to add up the weights. The registration of the counter 16 affords a means of estimating the mean specific density or gravity of the material.

Title: Improvements in or relating to the cooling of gasses in a recirculating gas systems
IPC: H02K9/26
Filed: 1944-02-11
Abstract: 572,284. Cooling gases. SHEPHERD, G. R. (Westinghouse Electric International Co.). Feb. 11, 1944, No. 2591. [Class 64 (iii)] In a circulating gas system, e.g., for cooling turbo-generators or other electrical apparatus, most or all of the gas in circulation through a closed chamber 6 is passed over a main cooler 16, and a relatively small portion of the gas is passed through an auxiliary cooler 33 which it leaves at a lower temperature than the gas leaving the main cooler, this lower temperature being above the freezing point of the principal condensed vapour obtained from the gas. The condensation which takes place in the auxiliary cooler 33 ensures that the gas circulating in the chamber 6 will be above dew-point temperature even after cooling by the main cooler 16. In the electric generator shown, hydrogen, carbon dioxide, air or other gas is circulated by a fan 11 at one end of the rotor shaft 8, over the stator 2, rotor 3, and through the cooler 16. The same inlet and oulet pipes 20, 21 are used to supply water of the same temperature to the heat exchange pipes 18, 34 of the two coolers 16, 33. A small portion of the air on the high pressure side of the fan 11 passes through the pipe 30 and control orifice 32 into the cooler 33, and returns through the pipe 36 to the chamber 6 on the low pressure side of the fan. The gas flows more slowly through the cooler 33 than through the cooler 16, and leaves the cooler 33 at a temperature which is only slightly e.g. 1‹F. above the temperature of the water in the inlet pipe and is consequently less, e.g., by 6‹F. than the temperature of the gas leaving the cooler 16. There may be a similar arrangement of cooling apparatus at the other end of the chamber 6.

Individual diode elements 42a, 42b, 42c (Fig. 3a) are supported on transparent glass or plastics 44. Conductor leads (not shown) may be deposited by evaporation techniques. A composite diode element (Fig. 3b) is formed into an array of 13 mesas (Fig. 3c) by means of an ultrasonic tool. A passivation layer 52 (Fig. 3d) of silicon dioxide is applied and then the transparent supporting matrix 44 is provided, e.g. by pressing into a heated glass blank so that the glass fully occupies the cut away spaces between the diodes. Alternatively a transparent polymer material may be used to encapsulate the structure. Openings 54 (Fig. 3e) are then formed in the matrix 44 directly above each diode element and the remaining portion of the monolithic substrate 46a is removed leaving only portions of the substrate 46 in the regions of the diode elements. Alternatively, instead of providing openings in matrix 44 the latter is lapped down to expose the "P" layers of the diodes, and a lens array 55 of epoxy is formed, e.g. by moulding. Thus raised lens elements 56 concentrate the light output of the diodes. The lower surface of the display may be coated with a phosphorescent layer 58 (Fig. 3f). The diode material may be gallium phosphide, silicon carbide, gallium phosphide-aluminium arsenide or gallium arsenide-phosphide.
