A buckle for connecting two strap portions comprises for each strap portion, a gripping edge 43 and an auxiliary anchorage 17 under which edge and anchorage the free end of a strap portion passes and then extends back over the auxiliary anchorage and under the gripping edge between the edge and the standing part of the strap portion, each auxiliary anchorage being mounted so that a tension in the standing part of the associated strap portion tends to move the anchorage towards the gripping edge to hold the strap portion between the gripping edge and the anchorage. The buckle comprises a frame 10 with end cross members 11 and 12 and upstanding side members 13 and 14, a control bar 16 and an auxiliary anchorage 17 on each side of the bar. Each auxiliary anchorage comprises an oblong bar which has a non circular trunnion 24 at each end pivoting in a non circular aperture 26 in each side member. A plate 40 encloses each side member and has transverse end places 41 each with a tongue 42 which bends over the edge of the corresponding cross member 11, 12 providing the gripping edges 43. The cross members have lifting tabs 46. The trunnions 24 and apertures 26 may have D or semi-circular shapes of differing curvature to provide limited rotation of the anchorage. The anchorage bar has a semi-cylindrical upper surface and rounded lower edges 22, 23. The edge of the auxiliary anchorage parallel with the gripping edge may have grooves. Rings or loops on the strap ends may permanently engage the standing part of the strap to prevent disengaging the buckle. Specification 877,473 is referred to.

Abstract: 368,620. Copying-telegraphy. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Ballentine, E. C. ; 2024, Euclid Avenue, Schenectady, New York, U.S.A.) June 6, 1931, No. 16584. Convention date,. Jan. 7, 1930. [Class 40 (iii).] In a picture-transmission system, a single carriage, in which are mounted a picturescanning device and a light-sensitive cell, is moved in a plane parallel to a flat picture-carrying member, and the movement of the scanning device and of the carriage are effected simultaneously from a single motive means. The picture 5 is supported on a fixed flat frame 3 mounted on the top 1 of a cabinet. A carriage 10 mounted on rollers 13 carries a drum 17 formed with a helical slot and rotated by a motor 15 which, through a gear wheel 24 and a rack 25, moves the carriage 10 slowly and transversely of the drum axis on a track 7. The picture is scanned by an elongated lightsource 22, fixed to the carriage, in conjunction with the helical slot of the drum and a longitudinal slot formed in the casing 20 of a photoelectric cell 19 within the drum and attached to the carriage. The motor 15 is mounted on and moved forward with the carriage 10. For the simultaneous transmission and reception of pictures the scanning apparatus is duplicated, with the photo-electric cell 19 replaced by an elongated glow-discharge lamp 30, and a lightsensitive sheet or plate 6 substituted for the picture 5. An image, such as an aerial view, may be transmitted by leaving an opening in the top of the cabinet and with the light-source 22 removed, the image is focused, with the aid of a screen, if desired, on the plane occupied by the picture 5.

Title: Document scanning machine
IPC: G06V10/20
Filed: 1970-04-09
Abstract: 1287064 Document scanning INTERNATIONAL BUSINESS MACHINES CORP 9 April 1970 [11 April 1969] 16821/70 Heading H4F When scanning a document composed of parallel and intersecting lines with a scan head of approximately the same width as the lines, if the head bisects a scanned line it may or may not register a line present, leading to errors, whereas if the head is much less in width than the line, redundant information is generated. The Specification describes a document scanning machine comprising a first group of scanners arranged side by side in a row perpendicular to the direction of scan for scanning at each scanning operation equal contiguous areas of the document, a second group of scanners comprising one scanner for each adjacent pair of the first group, which scans the contiguous halves of the areas scanned by the pair, and wherein each scanning operation scans one half of the area scanned in the previous operation. In Fig. 1 (not shown) the document is mounted on a drum which is rotatably stepped through half a scan line width for each scan and is moved laterally after 360 degrees so that the area scanned by the last scanner of the first group is scanned again by the first scanner of the first group. Light reflected from the document is focused on to the two rows of (nine and eight) scanners via a dichroic mirror beam splitter, each scanner comprising a fibre optic guide, which scans a square area on the document of side equal to the nominal width of the document lines to be detected, and an associated photocell. This is a first scan operation, the first and second scanners may scan areas a 11 -e 11  and adjacent halves of (a 11 -a 12 ), (a 12 -b 11 )... (d 12 -e 11 ) respectively, Fig. 5 and Chart 1, where the shaded regions 501, 503, 505, 507 represent document line. In the second scan the lower half of line a 11 -e 11  and the upper half of line a 21 -e 21  are similarly scanned, and in the third scan line a 21 -e 21  is scanned, the outputs of the photo-cells being shown in Charts 1-3. As each print is scanned four times the binary outputs of the two groups of photo-cells are interdigitated and passed to logic circuits, Fig. 2 (not shown), which reduce the amount of data by . A first circuit (202) compares the outputs (a), (c) of adjacent pairs of the first group and the associated one (b) of the second group, giving an output which corresponds to (a) if (a) and (b) are the same, and which negates (c) if (a) and (b) are different, and which is stored in a register (255). The results of the two succeeding scans are likewise stored in registers (251), (253). The contents of registers (255), (251), (253) are then compared in a circuit (271) similar in operation to circuit (202), Chart 4, and the output thereof gated, e.g. to a tape unit.

Abstract: 561,873. Asymmetrically-conducting resistances. STANDARD TELEPHONES & CABLES, Ltd., and SEARLE. A. M. Dec. 3, 1942, No. 17192. [Class 37] In a process of making rectifier elements by stamping &c. from a larger sheet, the seleniumcovered base-plate has those parts, at which the cutting operation will take place, covered with insulating material as by spraying on paint or varnish. Thus, in the case of discs with a central aperture, Fig. 2, the area 4 of and around this aperture 8 and around the place 3 where the outer cut will occur is covered with insulating paint, preferably after the selenium layer 2 has been converted to the rectifying modification.

Title: Improvements in or relating to the manufacture of yarns
IPC: D02G1/02
Filed: 1962-05-04
Abstract: An elastic ply yarn composed of man-made continuous filaments of natural or synthetic polymer(s) e.g. cellulose esters, polyamides, polyesters, acrylics, vinyls, polyolefines, is made by (a) imparting voile twist e.g. 500-900 turns/metre, individually and in the same direction to at least two multifilament yarns (b) subjecting such yarns, separately or after juxtaposition thereof, to a light setting and/or weak counter-twist whereby the first deformations formed in the single filaments are temporarily set or held (c) assembling the yarns with crepe twist e.g. 2000-2700 turns/metre, applied in the same direction as the voile twist (d) setting the assembly e.g. by wet (steam) or by heat (e) untwisting the set yarn by a number of turns greater than the crepe twist.  The steps c, d and e (in part) may be effected in one sequence on a false-twisting frame, e then being separately completed.  The component yarns may differ as regards materials, count, degree of twist, colour or finish in order to produce differential effects in fabric knitted or woven from, or including, the ply yarn e.g. one component may loop in relation to another or a variegated effect may be obtained.  Two similar elastic yarns of opposite residual twist may be knitted in alternate courses e.g. in the manufacture of orthopaedic support stockings.  The elastic yarn may be employed as weft with warp of polyamide yarn in a one-way stretch woven fabric.
