Title: Synchronizing method in a mobile radio system
Inventor: DAHLIN JAN E A S
IPC: H04L9/12
Filed: 1990-07-19
Abstract: A synchronizing method in a mobile radio system which operates with Time Division Multiple Access (TDMA) but which lacks global time reference for all base stations and mobiles in the system.      The inventive method is intended for ciphered transmission of data and speech in accordance with a given ciphering key (E2). When handing-over a call, the ciphering synchronism is lost. In accordance with the method, subsequent to hand-off (the time t2), the take-over base station (BS2) signals non-ciphered information (S1) to the mobile (MS) disclosing the number of frames (R1-R13) which shall pass until ciphering can again be commenced, calculated from a given frame (R1). Call information is transmitted in the following frame (R2), this information now being ciphered with the aid of a ciphering key (E1) different to the original key. This other ciphering key consists of a periodic bit sequence having a period which is equal to one frame interval.

Title: Method and apparatus for providing uniformly distributed filaments from a spun filament bundle and spunbonded fabric ob tained therefrom
Inventor: ZELDIN LEON M
IPC: D04H3/03
Filed: 1990-11-01
Abstract: ABSTRACT     A method and apparatus for providing uniformly distributed filaments from a spun filament bundle and a process for forming spunbonded fabric having superior uniformity and a favorable ratio between machine and cross direction tensile strengths.  The apparatus includes a fiber transfer tube and a pair of adjustable deflector plates.  The deflector plates form a channel having a tapering width for transporting the filaments in a stream of high velocity air. The apparatus may also include an electrostatic charging means for applying an electrostatic charge to each individual filament after it exits the channel.  The method for providing uniformly distributed filaments includes a first stage of separating the filament bundle by the high velocity stream of air and may also include a second stage of electrostatically charging the filaments to achieve a uniform filament separation.  The process for forming spunbonded fabric enables a fabric to be produced having a machine direction to cross direction tensile strength ratio less than about 1.5.

Title: Production of hydrocarbon derivatives
Inventor: RAMACHANDRAN RAMAKRISHNAN
IPC: C07C11/06
Filed: 1991-10-24
Abstract: ABSTRACT OF THE DISCLOSURE            A hydrocarbon derivative is produced by the vapour phase reaction of a hydrocarbon with substantially pure oxygen in the presence of a suitable catalyst in a reactor 2.  The product is removed in a scrubber 8, carbon monoxide, present in the reactor effluent as a by-product, is oxidised to carbon dioxide in a converter 16 and part of the gaseous effluent, comprising mainly carbon dioxide and unreacted hydrocarbon, is recycled to the reactor 2.  Removal of carbon monoxide from the recycle stream reduces the hazard of a fire or explosion in the reactor or associated equipment.  The use of carbon dioxide as the principal diluent increases heat removal from the reactor, thereby increasing the production capacity of the reactor.  If the hydrocarbon is benzene or a straight chain C4 hydrocarbon, e.g. butane, the product is maleic anhydride.  If the hydrocarbon is o-xylene the product is phthalic anhydride.  Other derivatives such as acetaldehyde, acrolein, acrylonitrile, methacrylonitrile, acrylic acid, vinyl chloride, and propylene oxide may alternatively be produced by appropriate selection of reactants and catalysts.
Patent CA-2054414-A1 (CA)
Inventor: BRAUN ERNST
IPC: B23D79/00
Filed: 1991-10-29
Abstract: ABSTRACT         Apparatus for removing burrs which develop on semifinished metallic products in the course of a flame cutting operation has a shaft which is driven to rotate about a horizontal axis and carries an array of round, polygonal and/or oblong cutting tools which extend radially beyond its peripheral surface.  The shaft is movable up and down adjacent the path of movement of metallic products with the burrs located at the undersides of the products.  When a burr is moved to a position above the shaft, the latter is lifted and is set in rotary motion so that its axially staggered tools remove and simultaneously fragmentize the burr.  The shaft is then lowered and the product is advanced to move another burr of the same product to an optimum position for removal of the burr or to provide room for transport of another product to the deburring station.  The tools can be used for removal of burrs from straight or curved metallic products.

Title: Shipping carton and display unit for tubes
Inventor: MILLER CHRISTOPHER J
IPC: B65D5/54
Filed: 1990-02-27
Abstract: ABSTRACT   A shipping carton where at least one divider is convertible without the use of tools to an attractive display case. The dividers in the carton reinforce the carton when used for shipping and hold the contents in substantially verticle alignment for display. The conversion without tools is facilitated by a tear strip which separates the upper and lower portions in all but one side. Scores separate the upper and lower portions of the one side and the divider. The scores and the tear strip in place connect the upper and lower portions to provide a strong shipping carton, but upon removal of the tear strip the scores are readily broken without tools to remove the upper portion and allow the lower portion to be used as an attractive display case.

Abstract: The gasification-combined power plant of the present invention has a structure wherein a fuel gas is generated by partially oxidizing a carbon-containing fuel(2)with an oxygen-containing gas(3)in the gasification apparatus(1), the sensible heat of the fuel gas is recovered by the heat ex-changer(4), char and dust are removed from the fuel gas by the dust collector(5), trace gas components, such as H2S and NH3, are simultaneously removed from the waste gas by the gas separation apparatus(6)based on dry physical adsorption of these components (for example, by a pressure swing adsorption method), the thus separated and removed gas containing high concentrations of trace gas components, such as H2S and NH3, is denitrated and desulfurized by the gas disposal apparatus (7)and then is discharged from the chimney(13)into the atmo-sphere.  With the simultaneous removal of the trace gas components at a high temperature from the fuel gas produced by the gasification apparatus, this plant simultaneously achieves both a high heat efficiency for the gasification-combined power plant as a whole and the reduction of sulfur oxides and nitrogen oxides in the combustion waste gas from the gas turbine.

Abstract: A process for producing  zeolite aggregates  involves providing a formable paste composed of zeolite, a binder composed of an organic/ metal oxide containing aluminum, a peptizing agent and water; forming the paste into an aggregate, preferably by extruding into an extrudate; curing the aggregate; hydro-thermally calcining the aggregate; and washing the hydro-thermally calcining aggregate with a washing medium. preferably followed by rinsing with a rinsing medium to remove residual washing medium from the aggregate. The washed and rinsed aggregate may then be permitted to equilibrate or is subjected to a drying procedure. Preferably, the washed and rinsed aggregate is again subjected to curing/hydro-thermal calcining. The resultant aggregates, such as extrudates, have an exterior surface with openings and interstitial spaces between particles of binder and zeolite which communicate by such openings between the exterior surface of the aggregate  and micropores of the zeolite; the aggregates also exhibit characteristics of crush strength greater than about 0.9 pounds per millimeter and a loss by attrition of less than about 3.0%. Regenerable catalysts, such as reforming catalysts, based on such aggregate also exhibit a catalyst activity pass through to the zeolite bound in the aggregate of at least 70% of the initial catalyst activity of freshly prepared zeolite, as well as exhibitingmore than about 70% of the reforming benzene yield that the reforming catalyst exhibited when similarly tested prior to being exposed to a hydrocarbon stream under specified reforming conditions of the catalyst activity test procedures.
