Title: Television Colour Synchronisation
IPC: H04N11/08
Filed: 1967-03-30
Abstract: 1,175,722. Colour television. BELL & HOWELL CO. 30 March, 1967 [30 March, 1966], No. 14540/67. Heading H4F. The subject matter of this specification is substantially the same as that described in Specification 1,175,721, but the claims are concerned with the method of operating the video colour display device whereby each colour signal of the line sequential colour signals is displayed during two successive line scans and two consecutively occurring line sequential colour-signals are displayed during each line scan. The specification also includes description of a field discriminator employed to index the sequencing unit at the start of every field in which a shaper responds to each horizontal sync. signal to produce a trigger pulse which is fed to two AND gates and a second shaper responds to each vertical sync. signal to produce an output pulse having a duration of one third the horizontal line scan interval which is fed directly to one of the AND gates and via a half line scan delay means to the other AND gate. The outputs of the AND gates thus set the sequencing unit into a first and a second state in the blanking intervals of the first and second fields respectively of each frame.

Abstract: 933,032. Sewing; embroidery. P. E. ARLIDGE. Dec. 14, 1959, No. 15026/62. Divided out of 933,031. Class 112. [Also in Group VIII] A method of stitching consists in sewing yarn into an open weave base by successively interlacing discontinuous loops of yarn with each other and with successive strands of the base whereby said loops provide a line of chain stitches, with the ends of the last loop providing tags which may be left loose or secured to the base. As shown, individual loops 20 of yarn are interlaced by a chain-stitch formation in an open-mesh base by means of a needle N having a pair of curved and spaced-apart limbs 10, 11 terminating at one end in a point 14 and at the other end in a hooked and bulged loop 17. A loop 20 is inserted in the end 17 and the point 14 is passed beneath a cross-strand 21 of the base, the needle then being drawn upwardly to position loop 20 with its free ends 20a above and at one side of strand 21, and its closed end above and at the other side of strand 21. A second loop is then inserted in the end 17 and the point 14 is passed through the first-inserted loop 20 and under the next cross-strand 21 to position the closed end of the second loop above the latter.

Title: Improvements relating to image pick-up tube circuits
Inventor: PERKINS DENIS GORDON
IPC: H04N5/228
Filed: 1954-05-22
Abstract: 787,025. Television. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 23, 1955 [May 22, 1954], No. 15123/54. Class 40 (3). Relates to a circuit for generating fieldscanning trigger pulses, the circuit having means whereby the timing of alternate pulses can be adjusted relative to the timing of intervening pulses so that the interlacing of the resulting raster may be controlled in a precise manner. The invention is applied to the control of scanning in a pick-up tube of the low beamvelocity orthogonal scan type with the object of reducing " focus flicker " which is considered to be due to a component at half-field frequency appearing in the tube output signal and related to the interlacing of the field scans. In Figs. 1 and 2, field-frequency pulses (a) at terminal 2 are applied to a frequency divider 1 to produce narrow pulses (b) which control a circuit 3 generating a sawtooth wave (c). This wave is then applied to a phase-splitting circuit 4 to set up paraphase versions (d) and (e) of the wave. A potentiometer 5 receives the two versions of the wave at opposite ends and produces an output at 6 determined by the position of the potentiometer tap. The output is zero when the tap is in the centre position and becomes a sawtooth wave of increasing amplitude either positive or negative as the tap is displaced increasingly in one or the other direction. The tap output is applied to control the operation of a variable-width pulse generator 7 triggered by the field-frequency pulses (a) from terminal 2. The output of the generator thus takes the form shown at (g1) or (g2). Alternate pulses 8 and 9 are of a datum width since the potentiometer tap output is zero at the time of triggering, whilst intervening pulses, such as 10a or 10b, have a width determined by the position of the tap, being greater than datum, as at 10a, for a positive output and less than datum, as at 10b, for a negative output. A circuit 11 sets up field triggering on the occurrence of the trailing edges of the pulses produced by generator 7 and thus produces a pulse train as shown at (h1) or (h2) where the timing of alternate pulses may be adjusted as shown at 14a or 14b relative normal timing indicated by dotted pulses 14. To prevent ambiguity when switching on so that the pulses (b) always occur at the end of a particular one of the two interland fields, circuit 1 may be replaced by a coincidence selector circuit, Fig. 3 (not shown), responsive to the coincidence between line and field trigger pulses which only occurs on alternate fields due to the normal half-line period difference in the relative timing of consecutive field pulses.

Title: Improvements in or relating to the manufacture of cellulose derivatives
IPC: D06M13/00
Filed: 1939-05-23
Abstract: 529,254. Cellulose derivatives. DREYFUS, H. May 23, 1939, No. 15297. [Class 2 (ii)] A cellulose derivative containing reactive radicles, e.g., hydroxyl, amino, or halogen, in substituent groups is treated with an organic reagent containing two or more radicles which will react with the reactive radicles in the substituent groups so as to effect reaction between the reactive radicles in the cellulose derivative and in the reagent. The cellulose derivative may be treated in powder form or in the form of filaments, foils, or other shaped articles. The processes of Specifications 518,225 and 520,691 are excluded. A mixture of cellulose derivatives containing two different types of reactive radicles may be treated with a reagent containing a radicle which reacts with one of the said types and another radicle which reacts with the other type of radicle. The reaction probably results in the formation of cross-linkages between cellulosic chains. The reactive radicles in the cellulose derivatives may be carboxy, acid amide, or nitrile groups. Cellulose derivatives containing ester radicles derived from di- or other poly-carboxylic acids in which at least one carboxyl group is unesterified may be treated. Adipic, glutaric, and phthalic are examples of such acids. Cellulose ethers obtained by reacting cellulose with chlor-acetic or ethyl chlor-acetate may be treated. The cellulose derivative may be one obtained by treating cellulose glycollate or hydroxy ethyl cellulose with phosphorus pentachloride. The reagent employed in the treatment may be, ethylene glycol, 1.5-pentane diol, diethylene glycol, butadiene dioxide, or adipic acid nitrile, when the cellulose derivative contains carboxyl groups. Adipic acid or phthalic acid may be used when the cellulose derivative contains nitrile groups. Salts of dicarboxylic acids, e.g. copper, magnesium, barium, or mercury salts, may be used for reaction with cellulose derivatives containing halogen. Cellulose derivatives containing about 2 acetyl groups to 0.25 to 0.5 of the group containing the reactive radicle per cellulose unit may be treated. In an example, yarn having a basis of a mixture of a cellulose acetate-chloracetate and a cellulose acetateaminoacetate is heated in the vapour of #- chlor-heptylamine. The treatment reduces the solubility of the products in organic solvents, reduces the tendency to creasing of yarns, and modifies the dyeing properties. Specifications 320,842; [Class 2 (ii)], 344,529, 485,768, 486,411 and 486,527 also are referred to.

Abstract: 840,681. Control of winding apparatus. GENERAL ELECTRIC CO. Ltd. May 15, 1958 [May 15, 1957], No. 15438/57. Class 78 (5). [Also in Group XXXIV] In a braking system for a mine winder, a winder cage is driven over a predetermined distance and is normally arranged to be decelerated over a predetermined part of this distance, fast braking being permissible only during the deceleration part of the wind and slow braking being normally permissible during the remainder of the wind, means being provided for automatically modifying the braking system to permit fast braking during the main part of the wind if the speed of the winder is below a predetermined value. In the arrangement illustrated, when the winder is in the main part of the wind a cam follower 7 is on the small diameter part of a cam 6 and a switch 3 is closed. If the winder is travelling at the same time, at more than 5 ft./sec., a switch 4, operated by a relay coil 9 energized by the output of a tachometer generator 10, is closed and " slow brake " valve 1 is moved to its upper position to permit slow braking by energization of solenoid 2 which moves piston assembly 13, 14 of valve 1 upwardly to throttle the exhaust of fluid through the valve from inlet 17 to outlet 18 and slow up the action of the brakes. When the winder is in the main part of the wind and travelling at less than 5 ft./sec., the switch 4 is open to permit fast braking. When the winder is in the decelerating part of the wind, i.e. the cam follower 7 is on the raised part 8 of the cam 6 and the switch 3 is open to permit fast braking irrespective of the winder travelling at a speed of less than 5 ft./sec.

Abstract: 1,184,596. Expansion joint for pipes or tubes. FOSTER WHEELER CORP. 4 April, 1967 [4 April, 1966], No. 15467/67. Heading F2G. [Also in Division F4] A metallic expansion joint 15 for pipe or tubes, e.g. vertical flues, comprises two identical legs 35 each having an opening therein to define an inner periphery 43. The legs 35 are axially disposed in spaced parallel relationship and an intermediate open ended conduit 37 is connected to and between the legs 35 to define with the legs a U-cross-sectioned fold. Means are provided for connecting each leg axially to one of the pipes or tubes 17, 19, the means comprising, for example flanges 23 and links 21. Each leg is formed into a plurality of corrugated corner portions, each corrugated portion on each leg having a corresponding corrugated portion on the other leg opposite and adjacent thereto in spaced relation, and straight portions. Each corrugated portion comprises at least one corrugation extending substantially in the direction of the outer boundary of the leg adjacent the corrugation(s). In the construction shown the expansion joint is formed by four corner sections 25, Fig. 4 being a section through one of these, and four straight sections 27. The straight sections may not be of equal lengths (Fig. 11A, not shown). Further the corner sections 25 are constructed from welded portions whereas the straight sections are pressed from sheet metal (Figs. 2, 3, 7, 8, not shown). The sections are welded together. The adjacent corrugations on the legs may be complementary (Fig. 4A, not shown) or opposed (Fig. 4). The angles subtended by a series of arcuate corrugations are disclosed in Fig. 5 (not shown). The expansion joint may be wedge shaped in vertical axial cross-section such that two non-coaxial pipes or tubes may be connected (Fig. 9, not shown). The annular space formed by the expansion joint may be protected from foreign matter by providing overlapping cylindrical members in the passageway through the joint (Fig. 11, 12, not shown). The intermediate, open ended conduit may be connected to the inner peripheries of the legs (Figs. 10, 11, not shown).
