Title: Improvements in or relating to connecting devices for coaxial cables
IPC: H01R13/646
Filed: 1947-09-16
Abstract: 628,696. Two-part couplings. STANDARD TELEPHONES & CABLES, Ltd., FAIRLEY DELAMARE, A. C., and JARVIS, F. L. Sept. 16, 1947, No. 25279. [Class 38 (i)] A connector for coaxial cables comprises identical halves each formed of an outer tube 1 closely surrounding an inner tube 2 in which is insulatedly mounted a strip centre conductor 3, the tubes being cut away for part of their lengths to provide mating portions when the halves are plugged together. The tube 1 is screwed into a clamping ring 22 and abuts a flange 6 on the tube 2, which flange is slotted to receive projections on the screwed end 8 of tube 1 to prevent the tubes rotating in one another. The centre conductor 3 is provided with a kink 7 and has one end turned over into an insulator 5 to prevent it and the tube shorting ; the kink increasing the contact pressure between the halves when they are plugged together. In a modification, Fig. 6, the centre conductor 17 is flat and is provided with spring fingers 18 to enhance its contact pressure. A waisted spring 19 is secured on the tube 2 to increase the contact pressure between the mating outer conductors. A mounting flange may also be secured to one connector half, thereby converting it into a jack, while the other remains a plug (Figs. 8A, 8B, not shown).

IPC: F41A3/10
Filed: 1944-12-16
Abstract: 595,265. Ordnance. BURNEY, SIR C. D. Dec. 16,1944, No. 25295. [Class 92 (ii)] A breech loaded quick firing gun, using fixed ammunition in which the wall of the cartridge case is perforated, has a breech chamber of greater diameter than the opening through which the ammunition is loaded, the gun having no cartridge ejecting means and being fitted with a sliding breech-block 5 in which a compressible obturating pad assembly is mounted. The breech-block shown moves in inclined guides and is raised and lowered therein by rollers 10 connected to an operating shaft 8. Rollers 7 on the block assist in loading a projectile into the breech. A spring 12 presses the seating cone 16 of the obturating pad 11 towards the face of the breech block. When the block is lowered from the closed position shown two spring-loaded plungers 15 temporarily hold the obturator assembly against downward movement, whereby the spring 12 gives a horizontal movement to the assembly. Specifications 586,749 and 595,293 are referred to.

Abstract: 962,975. Friction clutches. TWIFLEX COUPLINGS Ltd., and K. J. FREEMAN. Aug. 2, 1962 [July 14, 1961], No. 25680/61. Heading F2C. A centrifugally-engaged friction clutch of the type comprising a driving hub 10 carrying on resilient pivots 17, e.g. rubber bushes between sleeves 15, 16, levers 12 mounting friction shoes 23 engageable with a surrounding driven drum 25, the inner ends 14 of the levers moving radially inwards in the clutch-engaged condition to abut surfaces on the driving hub, is characterized by the provision of means on the driving hub for limiting the radial movement of the levers in the neighbourhood of the pivotal connection, or for limiting the radial movement of a part of the pivotal connection itself. In the form shown, convex surfaces 32 on the levers 12 can contact and roll upon inwardly directed concave surfaces 33 provided by radial lugs 11 fast with the driving hub 10, to limit the radial movement of the levers. In a modified construction, Figs. 3, 4 (not shown), the bolts 19 at the centres of the resilient pivots have axial projections engaging holes in circular plates surrounding and journalled upon the driving hub 10, to limit the radial movement of the pivots. As shown, links 20 pivot between the ends 13 of the levers 12 and the friction shoes 23, and are formed with balance weights 22. Pins 29 in the links 20 engage oversize holes 30 in the levers 12, to limit the relative angular movement between the levers and the links. Bolts 27 pivoting the links 20 to the friction shoes 23 at their ends 35 pass through radial slots 36 in a circular plate 35 journalled upon the driving hub 10, so that circumferential movement of all the shoes 23, &c. is equalized. In the modified construction referred to above, Figs. 3, 4 (not shown), helical springs surrounding each end of the shoe pivot bolts 27 and between the associated friction shoes 23 and links 20, allow axial movement of the shoes relative to the driving hub 10. Specification 609,550 is referred to.

Abstract: 1,073,193. Photographic processing apparatus. ITEK CORPORATION. June 22, 1964, No. 25776/64. Heading G2A. In a method of applying processing liquid to a film strip, each is in motion relative to the other. In the arrangement shown, the film strip 20 is guided between upper and lower plates 12, 14, and the processing liquid is pumped in through inlets 16, 18 so that it passes both above and below the film. The rate of movement of the liquid is about a hundred times that of the film. Thus the film is supported between bearing layers of liquid at both surfaces, and the turbulence produced In the fast liquid flow tends to give a more even development. The liquid is collected in a sump and re-circulated for further use. Fig. 5 (not shown) is a more elaborate arrangement comprising a processing head through which the film strip passes, and having a series of openings and conduits whereby the liquid passes over one face of the film and is then led to pass over the other face.

Title: Improvements in or relating to process of treating silk
IPC: D01C3/02
Filed: 1923-10-16
Abstract: Silk, either in skeins or in the piece, is degummed and bleached, with or without simultaneous blueing, by treating in a hot-water bath, to which is subsequently added an alkaline oxidizing agent with or without a dyestuff.  In an example of the process silk is boiled in water for some time and there is then added to the bath an alkaline oxidizing agent, such as sodium peroxide, percarbonate, perborate or persilicate, together with a soluble metal salt, such as sodium chloride, silicate, or phosphate, to prevent any deleterious action upon the silk.  These additions to the bath are preferably made in the form of a cold aqueous solution.  If the object is not to blue the silk, the latter is thereupon washed.  For blueing, the bath is made acid and an alkali violet dyestuff added.  The goods may be finished in a bath of neutral soap.  Instead of liquid baths as described above, foam baths may be employed.  The Specification as open to inspection under Sect. 91 (3) (a) refers also to the addition of sodaash to prevent the deleterious effect of the alkali.  This subject-matter does not appear in the Specification as accepted.ALSO:Silk, either in skeins or in the piece, is degummed and bleached, with simultaneous dyeing or blueing by first treating in a hot-water bath to which an alkaline oxidizing agent and a dyestuff are subsequently added.
