Abstract: 1375254 Apparatus for detecting recording and remedying faults in textile machines LEESONA CORP 18 Dec 1972 [20 Dec 1971] 58426/72 Headings DID and D1F In a textile machine such as a spinning frame in which a plurality of work stations wind bobbins a tender is provided which moves from station to station with detecting means to sense a plurality of conditions which indicate malfunctions. A data processing means responds to signals from the detecting means to produce a correction signal which activates further means for altering the machine operation accordingly. In the described embodiment the following are sensed by the detecting means: the spindle centre for location of the tender; a "flag down" condition which is defined as an inoperative state brought about in consequence of failure of past servicing attempts; a yarn wrap on a feed roll; the presence of a strand being fed through the machine; the presence of a full bobbin or the absence of roving on a bobbin. The data processing means is a logic circuit responsive to the malfunction signals and according to the faults detected may cause a full or partially full bobbin to be doffed and replaced by an empty one; render the station inoperative by putting a "flag down" or display an alarm signal. Such alarm signal would indicate a dangerous condition of the machine. The logic circuit may also collect statistical information by counting faults or service operations. The count may be per time, per spindle or per round trip of the tender. This information is displayed or recorded, e.g. on magnetic tape. A counting facility also causes the service cycle to be repeated up to a third attempt, in the event of failure, after which the station concerned is abandoned. Also the machine may be shut down if information gathered indicates very inefficient operation. Figs. 4 to 7 (not shown) show suitable detectors. Specifications 1,189,521, 1,223,912 and 1,282,041 are referred to.

Title: Television picture signal processing device

Filed: 1971-12-20
Abstract: 1336079 Television THOMSON-CSF 20 Dec 1971 [26 Oct 1971] 59183/71 Heading H4F An arrangement for horizontal and vertical aperture correction of a luminance signal from a television camera produces from an input luminance signal a "blurred-image" signal by combining the input signals from neighbouring points on the same and on adjacent scan lines, compares this with the input signal to produce by subtraction a contour signal, and generates a corrected output by combination of the contour signal with the blurred-image signal. This arrangement is stated to have an advantage over one in which the contour signal is added to the input signal in that in areas of uniform luminance the averaging effect reduces the noise level in the blurred-image signal. As shown the input luminance passes to two oneline delays 2, 3 and an adder 4 produces an average over three successive lines which is passed to 0À1 Ásec. delays 12, 13 to produce signals representing neighbouring positions on a line for addition at 14. The input signal suitably delayed by 2 and a 0À1 Ásec. delay 5, and the "blurred-image" output of 14 are passed through base-clipping circuits 6, 7 (which act as threshold circuits to prevent correction at low luminance levels) to a subtractor 9 generating the contour signal. This is passed through a further base-clipping circuit 20 and also through a filter 27 which removes components at colour subcarrier frequency to a variable-ratio adder 24 (controllable manually at 25) to produce a processed contour signal which is added to the blurred image signal at 26.

Abstract: 1,247,367. Making bellows; corrugating. T. H. THOMPSON. 13 Dec., 1968 [20 Dec., 1967], No. 59336/68. Headings B3A and B3E. [Also in Division F2] An actuator for hydraulic brake apparatus, or forming part of a brake master cylinder (see Division F2), comprises a bellows having a sidewall with convolutions or corrugations which tend to flatten out as the bellows is extended. As shown, a cup 60 made from plasticallydeformable material such as annealed berylliumcopper alloy of wall thickness 0À003 inch, Fig. 12, is formed into a bellows by introducing into it a plurality of semi-rigid plastic discs 67, having rounded edges, temporarily located on a mandrel 160. A radially - compressive forming force is now applied to the outside of the cup at the region between the two right-most discs 67 to produce a corrugation. The force may be provided by a flexible band, which is applied as the cup is rotated about its axis. This process is repeated between successive pairs of adjacent discs 67, and beyond the left-most one, until the stage shown in Fig. 14 is reached. Smaller axial wrinkles 72, Fig. 14, are also produced by this process. The mandrel 160 is now removed, and the outside of the bellows is sprayed with a layer 74 of plasticized elastomeric material such as natural rubber or neoprene. This kind of bellows is intended to form part of a brake actuator. A bellows intended to form part of a brake master cylinder, or part of an actuator, is shown in Fig. 26. It is made by arranging a plurality of forming rings 166, Fig. 23, around the outside; the rings may each be in two sections, and have circumferentially-spaced ridges on their inner surfaces to help form the wrinkles 72. An outwards radial force is applied between the first and second rings, Fig. 23, to produce an annular ridge 68b, and this process is repeated between successive pairs of rings. Then, elastomeric material 74b is applied to the inner surface of the bellows to fill the ridge portions 68b, Fig. 26.

Abstract: 1,194,650. Valves. CLEMAR MFG. CORP. 23 Dec., 1968 [7 Feb., 1968], No. 61125/68. Heading F2V. A valve has a spring-loaded closure member 32 secured to a stem 25 which is rectilinearly movable to open and close the valve by an electrically heated expansible thermal element 45 acting on a shaft 47 that abuts the threaded end 30 of the stem. A throttle nut 35 having a throttling plate 36 is threaded on the stem and is prevented from rotating by the abutment of finger 38 with stop 39 so that manual rotation of the stem by a cap 40 through a squared end 26 causes the nut to move towards and away from the seat 13 to adjust the rate of throttling. Rotation of the stem to the nut 35 downwards to abut the valve housing causes the stem to rise and open the valve independently of the thermal element.

A light-sensitive silver halide direct-positive photographic emulsion contains a water-soluble salt or complex salt of rhodium, at least one merocyanine or trimethine cyanine sensitizing dye and at least one magenta, yellow or cyan colour coupler. The compounds are called colour couplers in order to make their chemical structure clear and are not used to form coloured images in this case. Many colour couplers are listed in the Specification. The colour coupler is preferably present in an amount of from 7À5-150g per mole of silver halide. The emulsion preferably contains 10-800 mg of a sensitizing dye for light of long wavelength per mole of silver halide. The rhodium compound is preferably a rhodium halide or a hexahalorhodate. An organic desensitizer may be used in conjunction with the coupler. The organic desensitizer may be pinakryptol yellow, pinakryptol green or phenosofranine. The emulsion is preferably a silver chlorobromoiodide emulsion. The emulsion may also contain stabilizers, hardening agents or matting agents. These emulsions are resistant to fogging and sensitized only in the appropriate wavelength regions. The amount of sensitizing dye, required to attain the same sensitivity as that of conventional light-sensitive silver halide direct-positive photographic emulsions, can be reduced and dye-staining on the white background of the material after development can be prevented.
