Abstract: 890,960. Lined cartons; paper &c. bags. ALEXANDER & CO. Ltd., S. M. May 11, 1960 [Feb. 13, 1959], No. 5052/59. Classes 18 and 94(2). A package comprises a carton having four walls B, C, D, E, hinged together so as to be movable into a flattened or opened tube, and a liner formed by a lay-flat bag of approximately the same width as the collapsed carton and having its closed end projecting from an end of the carton walls to permit development of the bag when the carton is erected, the projecting portion of the bag being a trapezium the longer parallel side of which coincides with the end of the carton walls and the shorter parallel side 8 of which is a free end of the bag, on erection of the carton the trapezium taking the form shown in Fig. 7. The liner of polythene or polyvinyl chloride is formed from a tubular length of material, two separate layers heat-sealed together or a single piece folded over and sealed at its edges. The mouth 6 is open and the bottom is heat sealed at 4. The sum of the distances p, q between the centre point O of the end 8 and the ends r, s respectively of the edges 9, 10 of the carton which separate on erection is equal to the diagonal dimension t of the erected carton crosssection. When the carton is erected from the form shown in Fig. 6 by applying pressure in the direction of the arrows 11, 12 the liner takes the form shown in Fig. 7. The carton may be provided with or without end flaps b, c, d, e and the bag may be secured to all four or to one opposed pair of these flaps to make the bottom self closing on erection. Alternatively the endclosure may comprise solely the portion 7, Fig. 6. The bag may be secured to the whole of the internal face of the carton or to edges of the carton which separate on erection.

Filed: 1949-02-28
Abstract: 662,065. Explosive-testing apparatus. PRATT, J. S. COURTNEY. Feb. 24, 1950. [Feb. 28, 1949] No. 5411/49. Class 9 (ii). [Also in Group XIX] Apparatus for use in testing explosives comprises means for producing photographic records of high speed phenomena continuously over a period of time (Group XIX). The apparatus shown is arranged in a dark room with the shutter of a camera 9 open and a thin layer of explosive such as nitroglycerine on a block 1 of armour plate glass is detonated by an electric spark between an electrode 3 and a silvered strip deposited on the block 1 with the production of a luminous image AB, limited by an optical slit formed by two steel members 4, and formed on the photo-electric surface of an image converter tube 7 by means of a mirror 5 and a lens 6. In the tube 7, the photo-electrons released by the image AB form an electron stream focussed by an electron lens 11, impinge on a fluorescent screen 10 and are moved rapidly at right angles to the image AB by a magnetic field generated by coils 8 fed with a suitable time-base current so as to form a "graph" with respect to time of the motion of the explosive fiame from the centre of the slit outwards which "graph" is photographically recorded by the camera 9. It may be desirable to trigger the time base at the same time as or by the phenomenon while in other cases it is preferable to allow the time base to operate continuously for a greater period but including that of the phenomenon.

Title: Improvements in or relating to fibre drafting elements
IPC: D01H5/74
Filed: 1944-03-24
Abstract: A textile drafting element, such as a roller cover, cot, or high-draft element, comprises a vulcanised, oil-resistant synthetic rubber modified with animal protein, which is present in an amount sufficient to render the element substantially resistant to "lapping."  The preferred proteins are highly hydrolised gelatin, glue, casein, or egg albumen and 15 - 75 parts by weight may be added to each 100 parts of synthetic rubber, which may be of the chloroprene type, or the butadiene-acrylonitrile copolymer type, or an isoprene-acrylonitrile copolymer.  A tendency of the element to "eyebrow" may be reduced by incorporating particles of cork or other organic fillers, such as soft wood or balsa.  In one example, a mix was prepared including 100 parts of butadiene-acrylonitrile copolymer and 50 parts of highly hydrolised gelatin.  The mix was formed into a tube, placed on a mandrel, wrapped with tape and vulcanised at 300 DEG  F. for about one hour The tube was then removed from the mandrel, cut to the desired lengths, placed upon spinning rolls and buffed.  In another example, a mix including 100 parts of chloroprene, 50 parts of glue and 50 parts of 20 - 30 mesh cork was prepared.  In a further example, 50 parts of casein were mixed with 100 parts of isoprene-acrylonitrile copolymer.

Title: Process of producing crystallized ammonium nitrate with utilization of the reaction heat for the evaporation of water
IPC: D06C29/00
Filed: 1935-02-21
Abstract: <PICT:0441586/III/1> Ammonium nitrate in a form capable of solidifying on cooling is obtained from nitric acid and ammonia gas, while utilizing the heat of neutralization and solution for concentrating the salt, by intermixing nitric acid solution and ammonia gas in fine distribution in the lower part of a mass of fused ammonium nitrate already formed and boiling at normal or reduced pressure.  Vacuum treatment may be effected in a second vessel. Ammonia and aqueous nitric acid are heated in a preheater 2 to 70 DEG C. and are then introduced in fine distribution into the bottom of a saturator 1 filled with boiling ammonium nitrate solution.  The vapours escaping at 3 pass through a blower 4 into a saturator 5 which is supplied with fused melt from the saturator 1 via a pipe 7, with the aid of a vacuum pump 6.  Any ammonium nitrate in the vapours from the saturator 1 is thereby absorbed.  The salt free vapours are utilized in the pre-heater 2 and are then condensed in a condenser 8. The fused mass is tapped off through a pipe 7<a> into a water-cooled vessel 9 with the aid of suction applied via a pipe 9<a> and is then led into crystallizers 10.

Firstly a through-bore is formed through the central point of the blank with flattening or counter-boring of the blank at the bore orifices to delimit the length thereof. The blank is clamped along the through-bore axis, I, by means of a clamping device rotatable about two axes I and II in such a manner that the two axes I and II intersect with a further axis III of a tool in the central point of the blank in a variable angular relation. Fig. 6 shows a clamping device 2 clamping a joint piece 3. The clamping device is supported on a disc 6 pivotable around an axis II. A support 9 has a drill 11, a pin-end mill 10, and a tap 12 pivotable about axis IV. The drive means for the various parts may be electrical, pneumatic or mechanical. Fig. 7 shows a modification whereby receiving elements 8, 8<SP>1</SP> are rotatably mounted in a ring 13 which is also rotatable. Fig. 8 shows a number of devices mounted on a rotatable control board 21 surrounded by stationary machining units M1 to M10. Fig. 9 shows a further modification whereby three banks can be simultaneously machined. Each bank is mounted on rotatable mandrels 39, 40 which mandrels are supported by a plate 6 that is rotatable by means of discs 32, 33 about axis II. A machining unit 46 has three tools each rotatable about an axis III. The movements necessary to produce the tapped holes may be numerically controlled.
