Title: Hybrid catalysts for the deep catalytic cracking of petroleum naphthas and other hydrocarbon feedstocks for the selective production of light olefins
Inventor: LE VAN MAO RAYMOND
IPC: B01J29/48
Filed: 2002-01-28
Abstract: Provided herein are the hybrid catalysts used in the deep catalytic cracking of petroleum naphthas or other hydrocarbon feedstocks for the selective production of light olefins, in particular ethylene and propylene. The hybrid catalysts of this invention contain a chemically treated microporous crystalline silicate such as the pentasil-type silicalite, a mesoporous silica-alumina cocatalyst, into which may be incorporated aluminium oxide, molydenum oxide or a mixture of aluminum and molydenum oxides, and an inorganic binder such as bentonite clay. These novel catalysts show several advantages with respect to the classical steam (thermal) cracking : i) higher combined production of ethylene and propylene; ii) lower ethylenel propylene ratio; iii) much lower production of methane ; iv) much lower reaction temperature resulting in significant energy savings; v) easy in-situ regeneration using air as oxidant; vi) lower carbon dioxide and other volatile oxides emitted during the regeneration phase.

Title: Blow molded bottle with unframed flex panels
Inventor: OGG RICHARD K
IPC: B65D1/44
Filed: 2000-05-09
Abstract: A hot-fillable, slender, blow-molded plastic bottle (10, 110, 210) for use in containing hot-filled beverages. The bottle (10, 110, 210) has a sidewall (16, 116, 216) with various interactive zones of function. For example, some of the zones are primarily responsible for accommodating vacuum absorption, while other zones are primarily intended to rigidify the container (10, 110, 210) such as by providing post strength to improve container top loading capability. Although each zone may have a primary function, each zone also aids adjacent zones in providing their functions.   Thus, the entire sidewall (16, 116, 216), and not merely selected locations, reacts to the forces generated by the hot-fill process on the container (10, 110, 210).
Patent CA-2371593-A1 (CA)
Inventor: FORSTER IAN JAMES
IPC: H03F3/60
Filed: 2000-05-17
Abstract: The invention provides an amplifier circuit (100) for amplifying an input signal to generate an amplified output signal. The circuit incorporates a cascaded series of reflection amplifiers (400) arranged along a signal path and operative to amplify signals propagating in a forward direction along the signal path. The circuit is operative to counteract signal propagation in a reverse direction along the signal path, thereby hindering spontaneous oscillation from arising within the circuit (100). Incorporation of reflection amplifiers into the circuit enables it to provide high gain, for example 50 dB, whilst consuming low currents, for example tens of microamperes. The circuit (100) is especially suitable for use at intermediate frequencies in radio receivers such as mobile telephones.

Filed: 2000-05-03
Abstract: A bed assembly (1) for altering the position of a person supported thereon, includes a longitudinal support frame (5) having a support surface (23) for a person and a longitudinal cradle means (4) extending over the support surface. The cradle has a recess (10) extending along side portions of the cradle in the longitudinal direction.  The recesses are adapted to receive and engage cradle support engaging means (7, 7a). These means are mounted to the support frame in close relation to the recess and adapted to be extend-able and retractable in engaging relation within said recess so as to promote a change in configuration of the cradle. A first actuator (3) is disposed beneath the support frame and coupled to the engaging means for extending or retracting the engag-ing means. In a first condition the actuator causes the engaging means to extend towards and be received by the recess, causing the cradle means to move between a position of rest and a concave configuration about the central longitudinal axis. In a second condition, the actuator causes the engaging means to retract, returning the cradle to the rest position. Movement between the two conditions being controlled continuously, staggered or cyclicle so as to aid movement of the person lying on the support surface.

Title: Rapid battery charging method and apparatus
Inventor: PETROVIC VLADIMIR
IPC: H01M10/44
Filed: 2000-07-18
Abstract: Methods and apparatus for battery charging provide a charging cycle in which charging periods alternate with discharging periods. During the charging periods a lead acid battery is charged at a rate of about 0.55CEC amperes to about 0.65CEC, where C is the battery capacity in ampere hours. The charging periods have durations of about 60 to 180 seconds. During the discharging periods the battery is discharged at a rate in the range of about 0.05(EC to about 0.07CEC. The discharge periods have durations of about 10 to 20 seconds. By introducing discharging periods while charging the battery, the battery's internal resistance is deceased and less heat is generated during charging. The charging time is about 1- 2.5 hours for lead-acid batteries.

Title: Method of varying the ink density of the full tone in offset printing within a rotary printing machine
Inventor: WEICHMANN ARMIN
IPC: B41F33/00
Filed: 2002-04-18
Abstract: A method of varying the ink density of the full tone in printing within a rotary printing machine with an ink application system which can provide a constant quantity of ink which, in spite of constant ink supply from the inking unit, permits control of the full-tone density or adaptation of the raster tonal values in the print. The method includes setting the binary image on a printing plate. A basic raster of raster points, which determines the area coverage of the binary image, is produced on the printing plate for the variable-area image information. The basic raster is then superimposed on a fine microraster in such way that the area coverage of the basic raster is reduced by a percentage which can be set between 0% and 100%.

Title: Lead, zinc and manganese recovery from aqueous solutions
Inventor: GEISLER ROBERT A
IPC: C25C1/10
Filed: 2002-08-06
Abstract: Aqueous solutions containing lead, zinc and manganese are treated to recover these metals by sequential solvent extraction steps. Solvent extractants are selected to extract preferentially lead, then zinc and then manganese in that order. Any interfering metals are removed (as by ion exchange) before extraction. The loaded extractant phases are stripped with selected acids and lead, zinc and manganese each recovered from the strip solutions. Optionally calcium can be recovered when present. A preferred type of extractant (for lead especially) is substituted monothiophosphinic acids. A closed loop system is described which is advantageous with leachate from sulphide and carbonate ores.
