Title: Recovery of tobacco from cigarettes
Inventor: BOWYER PAUL
IPC: A24C5/36
Filed: 1969-08-30
Abstract: 1,249,541. Stripping cigarettes. IMPERIAL TOBACCO GROUP Ltd. 26 Aug., 1970 [30 Aug., 1969, No. 43262/69. Heading A2C. Cigarettes C are rolled under compression by a pair of contra-rotating converging conveyer belts 15, 20 to convert at least a surface layer of the tobacco therein into a substantially granular form, and then fed via a shoot 13 into a rotating cylindrical wire mesh sieve 14 where the tobacco escapes endwise from the unbroken cigarette wrappers. The recovered tobacco passes through the sieve 14 onto a vibrator conveyer 34, and the emptied cigarette wrappers, together with filter stubs if any, pass out of the outlet 35 of the sieve 14 optionally aided by suction. Unless the moisture content of the tobacco in the cigaretes C is sufficiently low, i.e. below 12%, for the tobacco to crumble when rolled, the cigarettes are passed through a drier 10 before rolling. In an alternative arrangement, either the upper belt is held immovable or it is replaced by a stationary plate. In a further arrangement, suitable only for filter tip cigarettes, the conveyer belts are driven about vertical rollers and the cigarettes are compressed whilst in a vertical attitude with their filters uppermost so that the crumbled tobacco drops down endwise out of the wrappers into a collector below and no separator is required.

Abstract: 1,148,619. Ceramic-metal seals; making lamps. GENERAL ELECTRIC CO. 28 Sept., 1967 [31 Oct., 1966], No. 44147/67. Headings B3A and B3V. [Also in Division C7] A method of preventing or reducing the increase in hardness of a niobium closure in the process of sealing it to a ceramic envelope with a sealing composition consisting primarily of alumina and calcia, comprises coating the outside surface of the closure with zirconium hydride before firing in a vacuum or inert gas at a temperature sufficient to melt the composition. Niobium caps 3, 31 may be secured to the alumina body 2 of an alkali metal vapour discharge lamp by a near eutectic mixture 16 of alumina, calcia and magnesia fired at at least 1500 C. Before assembling the parts between a support 15 and a weight 17, the caps and niobium tubes 6 brazed or welded to the caps are painted with a slurry of zirconium hydride in an acrylic binder and thinned with cellulose acetate. During firing, the zirconium hydride is effective in gettering oxygen and removes dissolved oxygen from the niobium. A cap, workhardened during drawing, may have its hardness partially restored by annealing and subsequently reduced to the original level during firing of the seal. At each end of the tube there is a tungsten wire electrode 8 on a tungsten shank 9 brazed in the crimped end of the tube 6.

Title: Continuous carburizing method
IPC: C23C8/22
Filed: 1975-10-29
Abstract: 1503179 Continuous carburizing MONSANTO CO 29 Oct 1975 [30 Oct 1974] 44704/75 Heading C7U The continuous carburizing of low carbon steel stock up to 0À051 cm thick, is carried out by passing the cleared strip S through a pre-heat zone 16 of a carburization furnace 4 in which a neutral gas atmosphere is maintained. The strip S then passes through baffles 20 into the carburizing zone 17 held at 950-1150C in which a carburizing atmosphere is maintained. The atmosphere has a high "carbon availability", (defined as the ratio Kg C entering the furnace to Kg of steel passing through the furnace per hour) in the range 0À010-0À080. On leaving the carburization zone 17, the strip passes through baffles 20 into a homogenization zone 18, wherein a neutral atmosphere, similar to that of pre-heat zone 16 is maintained, and held at a temperature above 800C. The homogenized strip is then passed, again through baffles 20, into a cooling zone 6, split into two zones 30, 22, in which cooling gas is directed on to the upper and lower surfaces of the strip. Cooling zone 30, in which the coolant is hydrogen, rapidly quenches the strip to approximately 600C in about 10 seconds while zone 32, supplied with nitrogen, further cools the strip to ambient temperature prior to recording on reel 51, via guide roll 48 and tension rolls 49. The residence time of the strip in the carburizing zone 17 is less than 10 minutes, the amount of carburization necessary being defined by a sootfree surface and a uniform microstructure of predominantly fine pearlite with a maximum of 5% proeutectoid ferrite present; the control being the "carbon availability" and residence time. Suitable material for treatment is 0À0254 cm thick black plate, and the C content can be increased from 0À08% to 0À6% with residence times of less than 10 minutes, using a high (0À02) carbon availability and a carburization temperature of 950-1150C.

The invention comprises a process of preparing N-carbamoyloxyphenyl carbamates of the formula in which R 4  and R 5  denote hydrogen atoms or aliphatic hydrocarbon groups and R 1 , R 2  and R 3  denote aliphatic, cycloaliphatic, araliphatic, aromatic or heterocyclic groups, any of which may carry one or more specified substituents, including halogen atoms and alkyl, halogenalkyl and alkoxy groups; alternatively, R 1  and R 2  may denote hydrogen atoms or, together with the adjacent nitrogen atom, may denote a heterocyclic group that may contain at least one further nitrogen atom or an oxygen atom. The process of the invention consists in reacting a compound of the formula in which X denotes a hydrogen atom, a monovalent metal or an ammonium, N-alkylammonium, N,N-dialkylammonium or N,N,N- trialkyl-anunonium group, with phosgene in the presence of an amine of the formula R 6 N(R 1 )R 2 , in which R 6  denotes a hydrogen atom or an aliphatic hydrocarbon group. In a modification of the process, the reaction of phosgene with the N-hydroxyphenyl urethane, which yields a chloroformic ester, may precede the reaction with the amine R 6 N(R 1 )R 2 . The reaction may be effected at 0-100‹ C., optionally in the presence of a solvent and an acid-binding agent, which may be an excess of the amine. A number of phenyl urethanes and amines for use as starting materials are specified, and numerous products obtainable by the process of the invention are listed.

Title: Optical projection systems
IPC: G01S1/02
Filed: 1961-12-14
Abstract: 930,355. Optical projectors. NATIONAL CASH REGISTER CO. Dec. 14, 1961 [Dec. 27, 1960], No. 44738/61. Class 97 (1). An optical projection system comprises a screen comprising a metachromic substance and two sources of radiation, one for directing a visible radiation beam containing an image on to the screen and the other for directing radiation on to the screen to change its light-absorbing characteristics, and means for causing a variable movement of said secondary beam over the screen to modify the image in the first beam. In the system shown, light from a source S1 which may be of any type, for example point, slit, monochromatic &c., is passed through lens 10, a part transparent object OB, lens 11 on to a screen MCM containing a metachromic substance and through there on to a viewing screen IM. A second light source S2 transmits radiation via mirrors 15, 14, a dichroic filter 13 which reflects ultraviolet light and green light on to the screen MCM. This latter radiation is of the type which changes the transmitting characteristics of the screen MCM so that a modified image of object OB is formed on screen IM. Mirrors 14, 15 may be rotatable by servomotors 16, 17 to form a " trace " on the modified image. Alternatively, the mirrors may be stationary and source S2 moved, or the source S2 may be replaced by a cathode-ray tube with a variable image on its screen. Screen 13 may be replaced by a lens which projects an image of source S2 directly on to screen MCM and not through lens 11. More than one source of auxiliary radiation may be used. Lenses 11, 12 may each comprise one of a series of lenses on a rotatable turret so that by selecting a particular lens 11, and lens 12 the size of the image on screen MCM may be varied and a corresponding adjustment be made to enable the size of the image on screen 1M to remain constant. Means may be provided for directing a beam of infrared light on to screen MCM or heating the screen to " erase " the trace formed by source S2. By having a series of screens MCM on a rotatable turret the information formed on each one by source S2 can be stored. S1 may also produce a radiation which varies the absorbing properties of screen MCM so that an image of object OB can also be stored.
