Filed: 1971-05-19
Abstract: 1319725 Locking hydraulic actuators DIAMOND POWER SPECIALTY CORP 19 May 1971 [21 Aug 1970] 15745/71 Heading F1D A linear drive mechanism comprises a piston reciprocable in a cylinder 10 and having a piston rod 16 around which are engaged a plurality of collet assemblies 20 for holding the rod 16 in a stationary position. Each assembly 20 has inner segments 65 with conical outer surfaces, the inner surfaces engaging the rod 16, and an energizing ring 66 can be moved axially on to the segments 65 to wedge them against rod 16. Each end of the stack of collet assemblies 20 is bound by a ring 71, 72 biased by a spring 58, 70. Rings 71, 72 can engage shoulder 74, 75 in the cylinder 10. Thus, when no pressure differential exists across the piston the rod 16 will be held fast by the collet assemblies 20. Hydraulic pressure on the pistons' upper face overcomes the frictional forces of the stack to drag the rod 16 down against, initially, the force of spring 70. After ring 71 reaches shoulder 74, the collet assemblies gradually lose their effect until the rod can continue downwards rapidly and unimpeded.

Patent GB-561378-A (GB)
Title: Improvements relating to the stabilisation of nitrocellulose, especially nitrocellulose photographic film base
IPC: G03C1/795
Filed: 1942-11-12
Abstract: Cellulose nitrate is stabilized by incorporating a small amount of a dihydrazide of an aliphatic dicarboxylic acid or a hydrazone of such a compound.  The hydrazide may be oxalic, malonic, succinic, glutaric, adipic, pimelic, suberic, azelaic, sebacic, lauryl malonic, tartaric, diglycollic, or thio-diglycollic dihydrazide, or diaminobiuret.  The amount of dihydrazide incorporated may be 0.0001 to 0.01 mols. per 100 grams of cellulose nitrate.  In the case of oxalic dihydrazide the amount may be 0.01-1 per cent based on the weight of cellulose nitrate. The stabilized cellulose nitrate may be used in the production of film base for photographic films particularly those containing high-speed sensitive emulsions.  The speed of such emulsions is resistant to change on storage, and the ability of the films to retain a latent image is improved.  The stabilizer does not materially alter the colour of the film base and it does not cause any appreciable fogging of the sensitive emulsion. If a dihydrazide is introduced as stabilizer to a solution of cellulose nitrate in acetone or other ketone, some hydrazone is formed.  The film-forming solutions may contain plasticizers and corrosion inhibitors such as urea, diamyl hydroquinone, thymol, carvacrol, or p-tert.-amyl phenol.  The stabilized film base may be subbed or backed with cellulose ester, protein, or resin coatings. The dihydrazides may be obtained by treating a methanol solution of the dimethyl ester of the acid with hydrazine hydrate.  Adipic dihydrazide is obtained by mixing dimethyl adipate with methanol and adding hydrazine hydrate to the solution.  White leaflets of the product form.  These are separated and washed with methanol. They may be further purified by forming a saturated solution in boiling water, decolourising with carbon, filtering and cooling.

[Also in Division H3] In a playback head and preamplifier arrangement having a magnetic playback head 10 connected to the input stage of a preamplifier 12, the frequency response of the connected playback head and preamplifier is substantially flat over a pass-band wide enough for video signals, the input stage has a lower impedance input than the impedance of the head's circuit and the preamplifier comprises a grounded emitter transistor input stage 13, a common base transistor intermediate stage 24 and a common collector transistor output stage 36 with negative feedback from the output stage to the base of transistor 13. The impedances of the input stage and head circuit are arranged such that a resonant peak of the head's circuit which occurs within the pass-band is swamped out. The input stage has a power gain which is sufficient to override noise contributed by following stages. The low input impedance of the amplifier is provided by a negative feedback path via capacitor 42 and resistor 41. The playback head may be used for reproducing signals from tape and is coupled to the input stage 13 by a rotary transformer 22. An emitter follower transistor 36 provides impedance matching of the output of the amplifier to a low impedance, coaxial cable 34. Reference has been directed by the Comptroller to Specifications 1,008,257 and 1,054,686.

Title: Improved method and machine for knitting seamless tubular articles
IPC: D04B1/28
Filed: 1956-05-25
Abstract: 835,541. Knitting. POWELL, R. C. May 25, 1956 [May 26, 1955], No. 16272/56. Class 74 (2). A seamless tubular forked article is produced on a flat bed machine having opposed beds of needles by a method comprising knitting at the or each crotch point between the branches a pair of intersecting yarn cross-overs, one crossover for each row knitted, the pair or pairs of cross-overs being formed by crossing the yarn being knitted from one bed to the other at the said point or points in both directions of knitting. In knitting a seamless glove by forming a wrist-band and part of a fashioned hand portion, then knitting a thumb tube, completing the hand portion and adding finger tubes, there are formed, at the crotches between thumb and hand portion and between adjacent fingers, one or more courses in which the crotch is defined by pairs such as 33, 34, of intersecting yarn crossovers, providing a web which prevents the formation of openings at these points. One to five courses, each including a pair of intersecting yarn cross-overs, are knitted at each crotch. Each digit is knitted in turn as an open-ended tube to be closed later, as by a draw-string. The yarn cross-overs defining the webs between first, second and third fingers are formed in the same set of courses, Fig. 9a. To anchor the yarn extending from the last course of the thumb or a finger (right-hand of Fig. 14) at the point where it enters into formation of the hand portion or of the adjacent finger, it is fed (e.g. at 50, Fig. 14) to the first adjacent needle in the same bed, of those needles about to knit it and then (at 51), to the opposite needle in the other bed, each of these needles drawing and holding a loop. The yarn is then passed back to the said first needle and a normal course is knitted, the held loops being cast off with the loops of that course, Fig. 16. To widen the hand or a finger, at the end of (say) a left to right traverse on (say) the front bed, the yarn is looped at 57 around a new needle in the back bed, then, at 58, around a new needle in the front bed and is then returned to the back bed for the knitting of a row of loops thereon from right to left, beginning with the new needle. The procedure may be repeated at the end of that traverse, loops 60, 61 being formed around new needles in front and rear beds; the needle bearing the loop 58 will be the last needle knitting the row of stitches formed by the front bed in the next left to right traverse. Specification 835,542 is referred to.
