Abstract: 1367886 Measuring displacement TI (GROUP SERVICES) Ltd 29 Oet 1971 [29 Oct 1970] 51357/70 Heading G4H In a photo-electric displacement measuring system nth order defraction patterns from a grating are reflected back from a planar reflector on to the grating to produce further patterns co-linear with the initial light beam incident on the grating, the further patterns interfering and producing periodic maxima in intensity as the grating moves. In Fig. 1 light from a laser 11, polarized in orthogonal directions is directed by mirror 12 on to grating 13 producing first order defraction patterns 15, 16 which are reflected back on to the grating producing further first order defraction patterns, 21 and 24 of which are co-linear with the original incident laser beam. The two further patterns interfere to produce intensity maxima for increments of the grating displacement equal to one quarter grating width. Beam splitter 28 divides the beam produced by the interfering patterns on to photo-electric detectors 30, 32 via polarizers 29 and 31 whose axes are respectively perpendicular and parallel to the axis of an one eighth wavelength plate 25, introduced into beam 16, whereby mutually perpendicularly polarized beams are received by detectors 30 and 32 whose quadrature outputs therefore indicate the extent and displacement of the grating. The arrangement of Fig. 1 is used for determining the degree of flatness of a line or plane along or over which the grating is moved, any upward or downward movement of the grating indicating irregularities in the line or plane (Fig. 2, not shown). Two or three of such arrangements may be combined to give a two or three dimensional output (Fig. 4, not shown). Instead of mirrors 17 and 18 in Fig. 1 retro reflector prisms in combination with mirrors adjacent the laser source may be used (Fig. 3, not shown) thereby avoiding precise optical setting up of the apparatus.

Abstract: 1,240,997. Cutting blowpipes. BRITISH OXYGEN CO. Ltd. 20 Nov., 1968 [21 Nov., 1967], No. 52983/67. Heading F4T. In an oxy-fuel flame cutting blowpipe the cutting oxygen valve is retained in position and operated by a one-piece resilient control member shaped to form a base arm 26 and a lever 27, the base arm being engageable with a complementary part of the blowpipe body to retain the valve housing in position, the lever being engageable with valve member 14 to hold the valve closed and being movable against the action of its resilience to open the valve. To assemble the valve, member 14 is located in housing 10, passed through hole 29 in the base arm and head portion 24 is slidably engaged with cut-away portion 32. With the axis of the lever perpendicular to the axis of the blowpipe, housing 10 is inserted into bore 6 such that the cut-away portions 30 of the hole 29 fit over brackets on the body of the blowpipe. The lever is then rotated through 90 degrees to assume the position shown in Fig. 1, with cut-away portions 30 engaging the corresponding brackets and tag 28 sitting in recess 33, thereby maintaining the control member in its correct position. In the absence of any pressure on the lever 27, the valve is in its closed position so that no oxygen flows to the cutting oxygen nozzle orifice. However, when lever 27 is depressed, the valve is opened, allowing a flow of cutting oxygen to take place, which flow is stopped when lever 27 is released and the valve is thereby urged back to its closed position.

Abstract: 1,215,037. Magnetic storage arrangements. INTERNATIONAL BUSINESS MACHINES CORP. 13 Nov., 1968 [14 Dec., l967], No. 53738/68. Heading H3B. In a word organized storage matrix in which their magnetic films 15, Fig. 1, are mounted on a conductive ground plane 14, each bit wire 13 has one end connected to a bit driver 19 and to ground through a matching impedance 23, while the other end is connected through a matching impedance 24 to the ground plane, neutralization of noise which follows the cessation of a write pulse and interferes with subsequent read out being effected by connecting the sense amplifier 12 between the ground plane and an intermediate point, e.g. the mid point, of the bit wire. Writing is effected in the usual manner by the coincidence of a bit pulse with a write pulse in a write wire 17, with the consequential induction of eddy currents in the ground plane which continue after the write operation terminates. Noise is therefore induced in the closed circuit comprising the read wire, the terminating impedances and the ground plane, the effect of which is neutralized by connecting the amplifier 12 to the electrical  midpoints of the closed circuit. In a modification, Fig. 3, the films 14a, 14b on either side of the electrical mid point connections are mounted on separate substrates 15a, 15b. The bit driver comprises transistors 35, 36, 37, 38 which are operated in pairs 35, 36 or 37, 38 for "write 1" or "write O" operations, respectively. The arrangement also applies where a separate sense wire terminated by the ground plane is used.
