Patent CA-2102809-C (CA)
Title: Process for manufacturing cellulose moulded bodies and a device for carrying it out
Inventor: ZIKELI STEFAN
IPC: C08L1/02
Filed: 1993-03-17
Granted: 2000-12-05
Abstract: To prepare cellulose mouldings, a solution of cellulose in a tertiary amine-oxide is moulded in a hot state and the moulded solution is introduced into a precipitation bath in order to precipitate the contained cellulose, wherein the hot moulded solution is cooled before introduction into the precipitation bath.  Cooling occurs immediately after the moulding process and preferably consists of blowing air horizontally on to the cellulose moulding. The process according to the invention allows spinning of the cellulose solution with a high fibre density without the spun fibres sticking together after emerging from the spinneret. In spite of the high fibre density, it furthermore allows the use of a long air gap between the spinneret and the precipitation bath, by which means sufficient time is generated in the spinning process to affect the textile properties of the fibres by drawing at the die (Figure 1).

Abstract: Capsules capable of controlled release of 2-chloro-N-(ethoxymethyl)-6'-ethyl-o-acetotoluidide herbicide enclosed in a polyurea capsule produced by the process comprising encapsulating waterimmiscible material within discrete capsules of polyurea without addition of a second reactant, whereby hydrolysis of an isocyanate monomer to form an amine takes place which in turn reacts with another isocyanate monomer to form polyurea, which comprises the steps of: a) providing, at room temperature, a dispersion of (i) a water-immiscible phase comprising the herbicide and an organic polyisocyanate in (ii) an aqueous phase comprising a solution of water, a surfactant and a protective colloid; and b) heating and maintaining said dispersion in a temperature range from about 40 °C to about 90 °C, whereupon said herbicide is encapsulated within discrete polyurea capsular enclosures. ?he microencapsulated composition performs comparably to non-encapsulated compositions of the same herbicide applied at the same application rates, while maintaining substantially lower mammalian toxicity compared with the nonencapsulated formulations.

Granted: 2000-02-01
Abstract: A method is provided for the direct cooling of synthesis gas in a catalytic exothermic reaction which is carried out in a reactor with one or more beds of a catalyst of a metal oxide catalyst. The method includes the first step of passing a reducing gas through the beds of the metal oxide catalyst. The catalyst is loaded between gas-permeable partitions without a space between the beds, thereby reducing the metal oxide catalyst to its metallic form. The metallic form has a smaller volume than the metal oxide. The total volume of each catalyst bed between the partitions shrinks, thereby leaving a void volume beneath each partition. The void volume constituting a mixing zone. The next step involves admixing the synthesis gas during its passage through the reactor with a cooling gas. The cooling gas is introduced into the mixing zone beneath each partition.

Abstract: A  self-bleeding  multi-stage  or  single-stage hydraulic    cylinder    system    is    disclosed   which automatically  bleeds  entrapped  air  from  within  the cylinder each time the cylinder is cycled.   The self-bleeding structure preferably includes a fixed elongated tube mounted to the base plate of the cylinder,  and an axially moveable elongated tube telescopically mounted on the fixed tube.  A biasing compression spring forces the moveable tube upward to a predetermined extent when the cylinder is extended.  Upon contraction of the cylinder, air trapped therein is purged or bled from the cylinder through the top end of the axially moveable elongated tube  into  a  fluid reservoir.   In the  final  stage  of contraction of the cylinder,  hydraulic fluid is  forced through the fixed and moveable elongated tubes thereby forcing  the  remaining  air  trapped therein out  of  the cylinder and into the hydraulic fluid reservoir.

Abstract: A paper web is monitored for measurement and manufacturing control by a stationary web sensor extending across the entire web which is raster scanned by the motion of the web. Massive amounts of data are processed by a look up table memory addressed by digitized sensor data and the output from a reference memory containing element specific information. The lookup table is loaded with data to define a characteristic or property of the web corresponding to digitized sensor data interpreted in view of element specific data from the reference memory. Rapidly processed data is stored in a memory in a form facilitating its display and interpretation by an operator of the web manufacturing machine and also control of the machine.      By controlling operation of the machine, uniformity of the web is substantially improved and, by taking the measurements closely adjacent the initial processing end of the web, corrections of nonuniformity in the web are quickly effected.      To measure and control absolute characteristics and properties of the web, a second, preferably stationary, sensor adjacent the finished end of the web monitors the web adjacent a takeup reel.      Alternately, for basis weight measurement and control, the weight of the takeup reel is monitored and combined with the web width and machine operating speed to determine an absolute web basis weight. Thus, uniformity of the web and absolute values of characteristics and properties of the web can be measured and controlled.
