Title: Improvements in and relating to the obtaining of fibres from flax, hemp, & similar plants
IPC: D01B1/30
Filed: 1926-08-23
Abstract: 269,389. Fabricord, Inc. June 12, 1926, [Convention date]. Breaking and scutching apparatus. - Flax, hemp and like stalks are cleaned before retting by subjecting them to repeated breaking actions and thereafter to an intermittent scraping action of increasing intensity in constantly the same direction. The uncured stalks are fed upon a conveyer 27 beneath a spreader roll 21<1> and through a spring controlled gate 29 to a series of pairs of rolls 22, 23, 32, 33, &c. of successively decreasing diameter which are rotated for an interval in the direction of the feed of the stalks and are then reversed for an interval so that the stalks, unable to return through the gate 29, are folded upon themselves to break the woody portion into short lengths and to strip it from the fibrous portion. From the final pair of rolls 39, 40 the fibrous material falls upon a conveyer 77 where it is carried upon bars 79 to the scraper blades 82. The roll 22 is driven by means of a rack 51, operated from a crank arm upon the main shaft 47, and pinion 52 which is loosely mounted upon the shaft 54 of the roll 22 and which carries at opposite sides thereof pawls 55, 56 engaging star gears 57, 58 secured upon the shaft 54. An adjustable mask 60 serves to hold the pawl 56, which operates to rotate the roll 22 in its reverse motion, out of engagement with its star gear 58 for part of its normally operative stroke so that the reverse rotation is only a fraction of the forward motion of the roll 22. The rolls 32, 36, 39 and the conveyer 27 are geared to move in unison with the roll 22, and the rolls 23, 33, 37, 40 are held by springs 44 against the rolls 22, 32, 36, 39 and rotated thereby. In addition to preeleaning the stalks the apparatus may be used to effect a final and complete cleaning of the precleaned and retted stalks.

Title: Improvements in variable electrical condensers
IPC: H01G5/38
Filed: 1924-09-03
Abstract: 243,794. Hale, G. W., and Radio Engineering Co., Ltd. Sept. 3, 1924. Condensers have a moving plate system arranged to move in a straight line and the leading edges of the plates of the two plate systems are so shaped that, when viewed by looking at right angles to the surfaces of the plates, the leading edges of one system appear to intersect those of the other system, throughout the whole range of the condenser to obtain a square low relation. The metal box 1 has a metal cover 2 secured by screws engaging lugs 3 and has an insulated terminal 7 for the fixed plates 4 which are separated by spacers from one another. Between adjacent plates 4 are a pair of mica sheets 9, and between each pair of these extend the tips of the moving plates 10. The latter are screwed to a cross bar 11 and metallically connected to the terminal 13 and box 1 by way of the operating mechanism. All the plates are provided with projecting parts extending towards one another, those of the fixed plates being shown at 14 and of the movable at 15. The parts comprise straight edges inclined to one another in pairs so that each pair makes a right angle, as shown. In Fig. 1 the tips of each set are against one another in the position of zero capacity, and it can be seen from Fig. 2 that the overlapping parts form a square, so providing a true square law variation. The operating mechanism comprises a resilient bridge-piece 16 carrying the moving system, the bridge-piece having apertured brackets 17, 18 for engaging the rotatable spindle 19 and a rib 27 engaging a steep-pitch thread 26 on a sleeve 21 secured to the shaft 19 bv means of a screw 22. The latter can be loosened so as to move the sleeve along the shaft to adjust the maximum and minimum values of capacity, these values being determined by the engagement of the brackets 18, 17, respectively with the ends of the sleeve. The spindle 19 has nuts 23 and a spring washer 24 to restrain it against endwise movement, and a knob 29, and may also have a pointer. The box 1 has a nut 28 for securing to a panel, and may be earthed if both sets of plates and terminals are insulated from it. By providing each set of plates with a threaded sleeve, the threads being of opposite hands, each set may be arranged to move in opposite directions, and, instead of the arrangement shown, a rack-and-pinion mechanism may be employed to move the moving plates. Instead of the edges making a right angle they may make any angle without departing from the square law principle. If the leading edges are made curved, the condenser mav follow a law different from the square law, and the capacity may also be varied by suitably shaping the dielectric sheets.

Abstract: 1397513 Blow-moulding MESSER GRIESHEIM GmbH 3 May 1973 [15 May 1972] 21081/73 Heading B5A In a blow moulding process, a preform is expanded and cooled by a low boiling point liquefied gas flowing thereinto through a single pipe having a valve and a blowing mandrel, the liquefied gas at the beginning of the inflow phase evaporating on passing through the pipe, valve and blow mandrel, subsequently any partially evaporating as a result of cooling the pipe, valve and mandrel and at the end of the inflow phase entering the preform in the liquid state. As shown in Fig. 5, a hollow article 1 is blow-moulded in mould 2, liquid nitrogen reservoir 7 provides blowing and cooling fluid through pipe 6, valve 5, past heater 8, through pipe 4 and mandrel 3. Pipe 4 has a high heat capacity which may be supplemented by heater 8 so that the nitrogen is initially evaporated thereby to provide gaseous nitrogen for blowing. As the pipe is now cooled as a result of the evaporation, final expansion and cooling is effected by a gas/liquid mixture. During final cooling, pressure on the article may be released, e.g. by raising the mandrel, so that the nitrogen is atomized finely. During initial blowing, the nitrogen preferably comes out of the nozzle as about the speed of sound. The medium may alternatively be argon or fluorinated hydrocarbon. The nozzle may be a naval nozzle. An outlet valve 9 enables the scavenging, e.g. with nitrgen and cooling to operating temperatre on starting up the machine.
