Title: An x-ray apparatus for measuring the internal stresses in materials
IPC: G01N23/207
Filed: 1958-05-09
Abstract: 881,234. Determining internal stresses by X-ray diffraction. KHOL, F. May 9, 1958 [May 11, 1957], No. 14898/58. Class 98(1). In an X-ray diffraction method of non- destructive determination of internal stresses in materials, a mechanical framework is provided which enables direct measurements to be carried out rapidly. As shown, X-rays from a slit source F are directed at the material specimen M. A detector D, such as a Geiger- M³ller counter, is rigidly fixed on an arm a which pivots about F, so that the detector axis is perpendicular to a. A second arm b is hinged at one end to a pivot m which coincides with the specimen M, and which can slide along the axis of radiation between F and M; the other end of arm b slides in a guide member on arm a. As the X-ray tube is moved towards the specimen, or vice-versa, both arms rotate, while detector D remains pointing directly at the specimen. The maximum diffraction intensity registered by detector D will occur at a particular value of the angle 2#. This enables the lattice plane distance d to be determined for a known wavelength value # of the interference radiation. A third arm P, in the form of a calibrated rule, is hinged at one end at a pivot o, as shown, and has at its other end a slot N in which engages a pivof S fixed at the free end of arm a. The distance oF = FS. Arm P moves over a measuring board, on which a straight line L is marked, whose distance from the pivot o is equal to a given multiple of half the wavelength #. A reading proportional to the lattice plane distance d is read off directly on the rule P, as in the apparatus described in Specification 824,994. To determine the strain value, it is necessary to take measurements for radiation falling on the area under investigation from two different directions. This can be done by two successive measurements, or by having two separate detectors.

Title: Improvements in or relating to selective gear transmission
Filed: 1937-05-28
Abstract: 499,864. Controlling change speed gearing. JACKSON, L. MELLERSH-. (Vaco Products, Inc.) May 28, 1937, No. 14905. [Class 80 (ii)] A fluid - pressure - operated gear-changing device is controlled by a selector which is constantly urged in one direction, manually-operable means being provided to move the selector in the opposite direction to any one of several positions and means being provided for releasing the selector step by step from a low to a high speed position. In the arrangement shown, vacuumoperated gear-shifting devices 15, 17 of the kind described in Specification 457,068 are controlled by a sliding selector valve 42, the power being derived from the inlet manifold of the engine; the selector valve may be replaced by a switch controlling solenoid valves. The selector 42 is urged towards the high-speed position by a spring 68, and may be moved in the opposite direction by a lever 64 actuated by a manual control lever 60 and engaging the end of a rod 66 fixed to the selector ; each gear change is produced by the depression of the clutch pedal 11, which operates a valve 31 in the vacuum pipe. Movement of the control lever 60 from the neutral position shown to the first gear position allows the valve 42 to move to the corresponding position, in which a lug 86 on the rod 66 engages a detent 88 and depression of the clutch pedal then opens the valve 31 to allow the gear-change to be effected and projects a detent 82 into the path of a lug 80 on the rod 66 ; the detent 82 is withdrawn when the clutch is re-engaged, and the detent 88 is withdrawn on completion of the gear-change by an extension of the pistonrod of the device 15. The change to second gear is effected similarly, a lug 81 co-operating with the clutch detent 82 and a lug 87 being engaged by a detent 94 to hold the selector valve until the gear-change has been effected by the device 17, the piston-rod of which then withdraws the latter detent to allow further movement of the valve if the control lever 60 permits. The lever 60 may be moved directly from the neutral or first-gear position to the third-gear position, the gear-changes then occurring automatically on successive operations of the clutch pedal. The secondspeed may be skipped, or its selection cancelled, by moving the lever 60 beyond the third-gear position, the tail of the lever 64 then engaging a rod 100 to withdraw the second-gear detent 94. The low speed may be arranged to be skipped also in a similar manner, or the lowspeed latch may be omitted so that low speed is skipped unless the lever 60 is held in the corresponding position.

Abstract: 544,593. Feeding sheets. ABBEY, A. (Bliss Co., E. W.). Oct. 17, 1940, No. 15406. [Class 100 (i)] In a sheet-feeding apparatus especially applicable for feeding metal sheets S from a pile 30 the sheets are separated by means of three suction separators 65 mounted on a shaft 67 which is driven by Geneva mechanism or by elliptical gearing so as to move slowly while separating a sheet, then to accelerate while feeding it through positions S<SP>2</SP>, S<SP>3</SP>, Fig. 5, in which an adjustable guide 125 directs the separated sheet to feed rollers 107, 111, and finally the suckers accelerate further until near the pile again when they are decelerated. To prevent double feed, the central sucker bends the sheet in two directions by being reciprocated in a plane normal to the plane of the sheet as indicated in Fig. 7. A pair of rollers 70 is arranged between the suckers 65, and after the nozzles 90, Fig. 6, of the suckers contact the top of the pile the suckers are raised by means of pistons 78 in cylinders 75 connected by apertures 87 and tubes 87<SP>1</SP>, Fig. 7, to valve plates 95, 97 which control the air pressures in the cylinders above the pistons, and also in the parts of the cylinders below the pistons which are provided with apertures 88 by means of which the suckers can be lowered into contact with the pile, and in the case of the middle separator is operated to effect the bowing of the sheet. The separation of the sheets is assisted by spring-pressed rollers 132 acting on the edge of the pile. The pile table is supported by pistons 19, Fig. 3, in a hydraulic cylinder supplied with fluid from a reciprocating piston pump operated by a cam 37 on the shaft 67. The mechanism for reciprocating the piston is prevented from following the cam 37 when the pile is high by means of lever mechanism controlled by a roller 62 resting on the pile.

Abstract: 1513422 Associative storage system THOMSON-CSF 15 April 1975 [16 April 1974] 15531/75 Heading G4A M data words arranged in M word columns and N bit rows are associatively searched against a P-bit keyword, P#N, by assigning the words to two sets in two simultaneous operations, the words in the first set having the same "1" bits as the keyword and the words in the second set having the same "0" bits as the keyword, matching words being those belonging to both sets. As described a selected one 10 of a group of holograms stored in a plane 1 is read on to two detector arrays 20, 21 to produce on each an array of M columns 20i, 21i and N rows 30j, 31j of light spots, a spot indicating binary 1 and no spot binary 0. A control generator 4 develops on two sets of N output lines P, (P#N), signals corresponding to the true and inverted bits respectively of a P bit keyword, the remaining (N-P) lines in each set carrying binary 0 signals. The true signals are fed to array 21, each signal corresponding to a binary "1" rendering a respective row modulator 31j transparent, the remaining rows remaining opaque. Only where a "1" bit of a sorted word corresponds with a "1" bit in the keyword is a detector at the corresponding row/column intersection of the detector array energized. The detector signals are summed along the M columns by resistors R1i to produce a signal indicative of the number of "1" bits corresponding to those of the keyword in the appropriate stored word. By comparing the signals with a threshold (details of the value of the threshold being given for both ideal and non-ideal cases) those stored words corresponding to the keyword in respect of "1" bits are identified. Detector array 20 receives the complementary signals from generator 4 and performs a similar function in respect of "0" bits, in this case the signals from each word have to be less than a threshold since only "1" bits passing through the modulators 30j energize the detectors. Matching words are indicated by corresponding match signals from both detectors by AND gates. In a modification the modulators 30j, 31j which may be Pockels effect devices, e.g. of deuterium monopotassium phosphate, are replaced, the detectors being arrays of photodiodes, each diode in series with an analogue gate (a transistor), rows of transistors being enabled by the control signals from generator 4.
