Abstract: 1,058,185. Treating tobacco. K. KÍRBER. Oct. 7, 1963 [Aug. 23, 1962], No. 32402/62. Heading A2C. [Also in Division F4] Loose tobacco is dried to a uniform moisture content in a hot air current whose temperature is adjusted dependently on the required moisture content by blending hot air with cool air and simultanously varying the amount of heat imparted to the hot air. In one embodiment the air current is produced by suction from a fan or blower 13 and the ratio of cold air entering on the left of an intake 3, and of air heated by elements 4 is adjusted by a valve 6. An element 8 measures the temperature of the air in a duct 1 into which tobacco is supplied through a sealed feeder 7. The moisture content of tobacco separated out at 10 is measured by a device 19 associated with a regulator 20 controlling the elements 4 and valve 6 whereby if the moisture content is incorrect the admitted amount of cold air is altered to correct the temeperature in the duct to a value which is then maintained by adjustment of elements 4. Separated air passes along a passage 12 including a valve 5 and measuring element 15 which keep the total air throughput constant to a centrifugal separator 17 where residual material is collected, the air leaving through a connection 18. In a modification (Fig. 4, not shown) the intake 3 is connected to the pressure side of a fan or blower and comprises a pipe containing heating elements 4 and a by-pass pipe for admitting unheated air in a proportion controlled by a butterfly valve. Throughput is kept constant by a butterfly valve and measuring element at the intake entrance.
Patent GB-976073-A (GB)
IPC: C07C69/82
Filed: 1963-08-16
Abstract: A process for the degradation and conversion of polyethylene terephthalate to dimethyl terephthalate comprises treating the polyethylene terephthalate with steam at a temperature of substantially 400 DEG C. and preferably in counter-current, and thereafter forming a powder having a mean particle size of substantially 0.001 mm., forming an aerosol from this powder and methanol vapour and/or an inert gas, reacting the aerosol in a turbulent flow with an excess of methanol vapour at a temperature from 250-300 DEG C. without using pressure, separating the reaction products from constituents in solid or mist-like form, and cooling with fractionation. The reaction may be accelerated by adding a gaseous catalyst such as hydrogen chloride. Zinc oxide or zinc compounds with inorganic or organic oxides may be admixed with the polyethylene terephthalic before or after forming it into a powder. In an example polyethylene terephthalate was treated in a vertical tube with oppositely flowing superheated steam at a temperature of about 400 DEG C. which left the tube at a temperature of about 200 DEG C.  The oily textile auxiliaries adhering to the polyethylene terephthalate waste distilled off with the steam, and the polyethylene terephthalate which accumulated as a melt beneath the tube, was continuously poured on to an endless steel band and solidified by cooling.  It was ground by means of conventional mills into a powder having a mean particle size of 0.001 mm. which was stirred with methanol to form a suspension which was then sprayed by means of a known adjustable Nubilosa nozzle with simultaneous introduction of 0.1% by weight, calculated on introduced polyethylene terephthalate, of dry hydrogen chloride gas into turbulently flowing nitrogen.  The aerosol of polyethylene terephthalate in the mixture of methanol vapour and nitrogen had a turbulent flow and was introduced tangentially at the bottom end of a heated reaction chamber.  The reactants discharged tangentially at the upper end of the tube into a container heated to 250 DEG C. having a column with a dephlegmator mounted on it causing further cooling of the reaction products and so controlled that only reaction products passed over which were still in vapour form at a temperature from 165 to 175 DEG C.  The separated products were cooled, again pulverized and reintroduced.  The reaction products remaining in vapour form were cooled by means of a second cooling assembly to 65 DEG C.  A liquid glycol and methanol mixture was formed and, after relatively slow crystallizing out, pure dimethyl terephthalate; which was removed by centrifuging and washed with methanol, was obtained.

Title: Improvements in or relating to self-locking screw threaded sealing devices
IPC: F16B37/12
Filed: 1947-12-10
Abstract: 684,832. Seals. THOMAS, R. E. Dec. 3, 1948. [Dec. 10, 1947] No. 32614/47. Class 146 (ii). [Also in Group XXV] Relates to sealing devices in the form of nuts comprising a resilient helix mounted in an unthreaded casing and consists in anchoring one end of the helix to the casing in such manner that a visible trace is left if the nut be unscrewed. The nut comprises a sleeve 5, Figures 1 and 2 bored to a close fit for the screw at each end but chambered out to receive a spring wire helix 7 the outer end 10 of which extends through a hole in the sleeve so as to be visible from the outside. This end may be secured by lightly brazing. On forcible removal of the nut the anchorage is broken and the end of the wire drawn in through the hole and deformed thus providing a visible indication. The inner end of the helix then engages an abutment 13 and further unscrewing of the nut becomes easy. In modifications employing fewer turns of the wire the inner turn may be of polygonal form. The inner end of the wire may be bent to be parallel to the axis and may pass under the adjacent turn which may be cranked or offset to facilitate this. The wire instead of being of thread form may be such as to permit tapping after coiling and in this case the pitch of the helix need not be the same as that of the thread. The casing 5, Fig. 4 may be a press fit in a hole in a lug 15 and in this case a hole 16 is drilled through the lug in line with the hole 10 so that the anchored end of the helix may be inspected. Helices for use with square threads are of round or triangular section of wire of size too great to enter completely into the threads. The Provisional Specification denotes other constructions, in one of which a nut tapped to fit the bolt at one end is hollowed out to receive therein helix at the other. In a further form in which flat strip is employed for the helix the outer turn may be of less width than the inner turn. The strip may be sufficiently thin so that the turns may be side by side in the worm thread and part of the strip is joggled and cut away beneath it to pass over the cuts of a thread into the adjacent groove. A helix of wound wire may be applied to the reduced end of a bolt the leading end being anchored in a transverse hole. The helix may be formed from flat strip, wide enough when corrugated to engage more than one thread.

Title: Control system for regulating the speed of deuterium-tritium tip ontrolled nuclear fusion reaction
IPC: F41F1/00
Filed: 1973-07-09
Abstract: 1366285 Apparatus for controlling the velocity of a projectile through a gun barrel A P PEDRICK 9 July 1973 32707/73 Heading F3C Means for projecting a bullet 5 along a gun barrel 2 is associated with means for controlling the velocity of the bullet. The latter means comprises a disc 15 rotated by a constant-speed motor 21, the disc leaving conducting and non-conducting zones arranged to perform a switching function in a circuit for energizing a coil 18 which surrounds the barrel. If the bullet traverses a length D of the barrel in a predetermined time, no energization of the coil takes place, but if the bullet travels faster than its predetermined correct velocity, the coil is energized to create a magnetic drag on the bullet. This speed-control system is designed for use in an apparatus, Fig. 1 (not shown), wherein three guns, all intended to be fired simultaneously and to have their bullets controlled to the same speed, are used to cause three deuterium and/or tritium pellets mounted on the bullets to come together at a given instant, laser radiation being trained on the point of impact of the pellets just before they collide. The intention is to bring about nuclear fusion in the same general way as is described in Specifications 1,207,698 and 1,282,391.
