Title: Method for the manufacture of yarn and the yarn obtained by the application of said method
IPC: D02G1/02
Filed: 1972-07-04
Abstract: 1380004 Sized yarn HOLLANDSE SIGNAALAPPARATEN NV 4 July 1972 [5 Oct 1971] 31187/72 Headings DID D1F and D1W In a method for the manufacture of yarn from a roving of staple fibres consisting of at least two components one of which contains a size, the roving is wetted to activate the size drafted and dried. The completion of the sizing process may be carried out under increased temperature e.g. using a steam treatment. In a preferred embodiment, a roving 1 is taken from a package 2 and fed via guides 3 through a bath of water 4 which may contain a wetting agent. The wet roving is then drafted between pairs of rollers 5, 6 and 7, 8 to form a fibrous sliver 9 which is false-twisted by means 10 and cross-wound on a package 12 by means of pressure roller 13 and traversing mechanism 11. The cross-wound package 12 is then steamed to complete the sizing and cooled. The activation of the size component may take the form of expanding, gelatinising or partial dissolving, the activated size component forming a bond with and between the other fibre components. The yarns obtained may be twist-free or have a relatively low twist.  The fibres which do not form the "sizing agent may be selected from cotton, polyamide, polyester or stabilised polyvinyl alcohol fibres. The fibres which do form the sizing agent may be selected from unstabilised polyvinyl alcohol, alginate, or di- and tri-acetate.

Title: Improvements in or relating to aircraft with auto-rotative wings
IPC: B64C27/02
Filed: 1928-10-27
Abstract: 327,381. La Cierva, J. de, and Cierva Autogiro Co., Ltd. Oct. 27, 1928. Machines with rotary wing systems; starting.-Aircraft of the type having wings rotatively mounted for actuation by the relative air flow in flight have their wings set in motion for starting by means of displaceable surfaces arranged to deflect the slipstream of the propelling airscrew or airscrews through the disc area swept by the wings; the displaceable surfaces may be portable and separate from the aircraft or be incorporated in the structure thereof. According to one form the normal tail plane F is adapted to be set at a considerable negative angle of incidence being hinged at its trailing edge and operated by a bell-crank lever and connecting-rod from the pilot's cockpit, as shown in Fig. 1. Vertical fins and rudders XY may be disposed at the extremities of the span of the tail plane F to prevent lateral dispersion of the slipstream from the airscrew E. In a second form, a spring- loaded conical roller N, Figs. 4 and 6, is mounted on each side of the fuselage A with its axis inclined to the longitudinal axis of the fuselage. To each roller N is attached along one edge a segmental piece of stiff textile fabric 0; the roller N incorporates a spring after the manner of a roller blind. The other edge of the fabric 0 is attached to one arm P of a bell-crank lever pivoted at P' and having its second arm P<2> connected to a slide Q adapted to be operated against the. restraint of a spring Q<1> by means of a cable R. The cable R is connected to a lever under the. control of the pilot; backward movement of this lever causes the two deflectors 0 to be expanded as shown in Fig. 6. Spring loaded flaps may be arranged to cover the openings in the sides of the fuselage when the deflectors are housed therein. More or less vertical surfaces adapted to fold downward when the deflectors O are returned to their housings may be provided on the arms P.

Title: Method of producing a mixture of calcium nitrate and ammonium nitrate
IPC: C05C1/00
Filed: 1928-10-30
Abstract: 310,276. Kunstd³nger Patent - Verwertungs-Akt.-Ges., (Assignees of Liljenroth, F. G.). June 5, 1928, [Convention date]. Addition to 301,486. Manures.-In the method of obtaining a mixture of calcium nitrate and ammonium nitrate by treating calcium carbonate, obtained by the action of ammonia and carbon dioxide on calcium sulphate and with which some of the ammonium - sulphate formed is associated, with nitric acid, as described in the parent Specification, the reaction is carried out so that calcium sulphate is crystallized as semi-hydrate, which is re-crystallized as gypsum for separation from the solution. The formation of semi-hydrate is secured by carrying out the reaction at a high temperature or in a concentrated solution, and the re-crystallization by cooling or dilution. Small gypsum crystals or fragments separated from the product of a previous operation are added to the solution to promote the re-crystallization.

Title: Process for obtaining peat
IPC: C10F5/02
Filed: 1928-10-30
Abstract: 328,658. Korelin, M. N. Oct. 30, 1928. Peat, preparing. - In a process for obtaining peat for the production of briquettes, a comparatively shallow layer of the bog is cut stripwise and the peat on alternate strips is torn up and deposited loose and disintegrated in the same place. The disintegrated peat is then heaped up into ridged beds on the adjacent uncut strips and allowed to dry, the surface layers of the ridged beds being periodically raked down so that a new bed or heap is formed on each side of the original ridged bed. These two new beds may be recombined and the process repeated until the peat is sufficiently dried, whereupon it is conveyed to the briquetting devices. Instead of raking down the dried material from the ridged beds, it may be removed pneumatically and conveyed to the briquetting devices. After the dried peat has been removed, the strip beneath it is treated, the adjacent strips serving as drying surfaces. Machines similar to snow ploughs may be used for heaping the material into ridged beds.

As described, a scanning electron microscope includes a gun chamber 12 communicating with a specimen chamber 24 via an aperture 28 which permits passage therethrough of an electron beam from the field emission cathode 10, and the maintenance of a pressure difference between the two chambers. To assemble the tube, a pre-evacuated gun chamber 12 with an integral ion pump mounted therein is secured by a flange 30, Fig. 2, and clamp 46 to a flange 44 of the specimen chamber, whereafter the metal sealing diaphragm 32 is punctured by movement of the cam 50 axially to a position beneath the hollow punch 36, with subsequent rotation to force the punch against the diaphragm (Fig. 3, not shown). In an alternative arrangement (Fig. 4, not shown) the punch is forced upwards by the tightening of an external screw collar which abuts against a split ring (38) on the outside of one chamber and engages with a screw thread on the outside of the other chamber. After puncture, the punch remains in place and the electron beam passes through its central passage. The gun chamber may be of glass, metal, or ceramic.

Filed: 1945-11-23
Abstract: 602,779. ' Inductance and capacitance measurements. MATERIEL ONDIA. Nov. 23, 1945, No. 31710. Convention date, April 7, 1944. [Class 37] The value of an unknown reactance or resonant frequency of an oscillatory circuit is determined by observing the change in a variable parameter of a further oscillatory circuit 24 of given frequency, which its insertion therein entails. In the embodiment shown, the frequency of oscillator 1 is determined by inductance 2 and condensers 3 and 4. Condenser 4 is varied cyclically by motor 5 through drive 6 and shaft 13, and inductance 2 may be the element to be measured and condenser 3 a fixed element, or vice versa. The output of oscillator 1 is applied to sharply tuned amplifier 7 which supplies neon tube 8. When the condenser 4 passes through the value at which the frequency of the oscillator 1 corresponds with the acceptance peak of the amplifier, the tube 8 ignites, and being rotated over a graduated scale 9 by the shaft 13, its angular position will give.the value of the unknown element directly. In a modification, Fig. 2 (not shown), the unknown element is compared with a standard, a further rotary or electronic switch being embodied, by means of which the standard and unknown elements are switched into the oscillator circuit during alternate revolutions of the neon-tube. Further modifications (not shown) embody the substitution of a thermionic reactance, a low frequency generator and a cathode-ray tube for the variable condensers 4, shaft drive and neon tube respectively. It is stated that a variable element may be compared with a variable standard incorporated in the amplifier unit.
