Patent CA-2081788-A1 (CA)
Title: Blast furnace tap hole drilling machine
Inventor: LONARDI EMILE
IPC: C21B7/12
Filed: 1992-10-30
Abstract: A machine for boring a tap hole of a shaft furnace is presented for use in conjunction with a lost-rod process. In this process, a metal rod is driven into a botting mass, before it has completely hardened, and is removed later for opening a tap hole. Driving-in of the rod is performed with the aid of a to-and-fro movement of a clamp which can move over a mount through action of a first jack. Removal is performed with the aid of a continuous reverse movement of the clamp through the action of the first jack and of a powerful drive means, for example a second jack, driving the first jack towards the rear of the mount.
Patent CA-2082585-A1 (CA)
Inventor: CARTER J WARNE SR
IPC: F03D1/00
Filed: 1992-11-10
Abstract: Wind-driven electric generator apparatus has a generator head supported on a tower for free-yaw movement and for free-pitch movement within predetermined limits.  The generator head has a downwind rotor with a pair of elongated blades mounted on a hub that is rigidly attached to a rotor shaft driving an electric generator.  The blades are flexible and have a coning angle therebetween that varies with wind velocity.  The generator head is capable of aligning itself with the wind direction azimuthally and elevationally. A yaw brake prevents an excessive yaw rate.  In a most preferred embodiment, pitch movement and yaw movement beyond small angular ranges are regulated, and an electrohydraulic yaw drive system corrects gross azimuthal misalignment with respect to the wind direction.

Inventor: SHVEIMA JOSEPH S
IPC: C08F2/00
Filed: 1992-12-03
Abstract: 32846CA ABSTRACT OF THE INVENTION A process for preparing pillared chromium phyllosilicate clay .alpha.-olefin catalysts is disclosed This process utilizes palygorskite and sepiolite clays. The pillaring of said clays comprise the steps of: (a) preparing a hydrolyzed first solution by dissolving a chromium salt and a base in water, heating said first solution to a temperature in the range of about 20°C to about 100°C while stirring continuously until the solution reaches a pH in the range of about 1.5 to about 2.5 and thereby producing a master batch; (b) diluting said master batch with water to produce a diluted second solution and heating said diluted second solution to produce a heated second solution; (c) adding a solid clay selected from the group consisting of sepiolites and palagorskites to said heated second solution, and continuing heating; (d) recovering said pillared chain silicate clay; (e) drying said pillared chain silicate clay to form first product; The activation of said clays comprise the steps of: (a) heating said first product at a temperature in the range of about 150°C to about 500°C and for a time period in the range of about 30 minutes to about 10 hours in an inert atmosphere; (b) thereafter reheating said first product at a temperature in the range of about 500°C to about 900°C and for a time period in the range of about 1 hour to about 50 hours in an oxidizing atmosphere and recovering said catalyst composition. This results in clay catalysts which polymerize .alpha.-olefins.

Title: Differential pressure sensor utilizing opto-reflective sensor
Inventor: KEMP STEPHEN J
IPC: G01L9/00
Filed: 1992-12-30
Abstract: A differential pressure sensor utilizing an opto-reflective sensor comprising a diaphragm with a top and a bottom, the diaphragm having an optical reflector mounted upon it. The diaphragm is mounted in a housing, wherein the housing has a first inlet port and a second inlet port, the first inlet port providing a first pressure to the top of the diaphragm and the second inlet port providing a second pressure to the bottom of the diaphragm.      An opto-reflective sensor is mounted in the housing, wherein the opto-reflective sensor provides an optical signal to the optical reflector. The optical reflector reflects the signal back to the opto-reflective sensor, wherein the differential pressure sensor calculates the distance of the optical reflector from the opto-reflective sensor in relation to the relative intensity of the reflected optical signal. The differential pressure sensor then calculates the differential pressure between the first pressure and the second pressure based on the relative intensity of the reflected optical signal.

Title: An integrated process for making methanol and ammonia
Inventor: LEE JING M
IPC: C01B3/34
Filed: 1993-01-22
Abstract: An integrated process for making methanol and ammonia from a hydrocarbon feed stock and air is disclosed. An air separation unit is used to produce substantially pure oxygen and nitrogen gas streams. The oxygen gas is used in the secondary reformer to increase the operating pressure of the reformers so that compression to methanol synthesis pressure may be done by a single stage compressor. The nitrogen gas is used to remove carbon oxides impurities from a ammonia synthesis feed stream in a nitrogen wash unit in addition to supplying the nitrogen reactant in the ammonia synthesis gas. Use of nitrogen wash obviates the need for steam shift and methanation reactions used in prior art processes.

Title: Swivellable seat cushion
Inventor: CHUN BONGSOO
IPC: B60N2/14
Filed: 1993-04-28
Abstract: ABSTRACT      To enter into  and exit from seats in a  tight space such as the  interior  of a  typical motor  vehicle,  it is necessary to perform   uncomfortable   body    manoeuvres   often    involving uncoordinated  turn  of upper  and  lower  bodies. The  situation becomes  worse for  people with  permanent or  temporary physical handicaps.    In this invention, a cushion, when placed on a vehicle seat, is  made  to  swivel  toward  desired  directions  by  a   simple coordinated body turn and thereby provide, cheaply, features that are available in seats specifically designed to swivel.

Abstract: A continuous input system allows a system operator to continuously input a plu-rality of polysemous icon symbols to access stored (l3, l4) morphemes, words, phrases, or sentences corresponding to an icon se-quence. The system, with automatic mode selection for the input system, containing a plurality of character and symbol keys (4), allows for automatically selecting (4, 5) of the icon (12, 17, 22) mode, a character or word prediction mode (14, 15, 23); and even a subsequent suffix mode, to allow a user to enter morphemes, words, phrases, or sen-tences sequentially. Further, by utilizing the character and word prediction (l4, 15, 23) modes, including the suffix (27, 32) mode; words; phrases or sentences corresponding to non-accessible icon sequences can beau-tomatically activated without having to man-ually switch out of the icon mode or select the character and word prediction mode.    Such automatic icon, word prediction, char-acter and suffix mode selecting, thereby al-lows continuous text (16) or speech (18) gen-eration with a minimal number of input key (4) activations necessary for a system opera-tor.

Inventor: DALLAS L MURRAY
IPC: E21B33/00
Filed: 1994-10-18
Abstract: An apparatus and method for completing or recompleting wells for production is disclosed. The apparatus and method are particularly adapted to the completion of oil or gas wells having a plurality of production zones. In particular, the apparatus is useful for oil or gas wells having production zones which require stimulation prior to initial production of the well, or producing wells which require recompletion in order to open new zones or to reperforate and stimulate existingzones from which production has slowed down or ceased. The apparatus comprises aheader spool having a pressure rating that is about as high as the burst pressure rating of the surface casing of the well. The header spool is mounted to a casing spoolbefore a 1 is placed on the well. The header spool has an internal passage which is at least as large as the diameter of the casing in the well. This permits an efficient completion of the well after the casing is cemented in. The apparatus in accordance with the invention permits the unobstructed use of a full range of tools including casing perforation tools, blowout preventers, casing plugs, logging tools, fishing tools, and other apparatus required in the completion of a well for production. The method for completing wells involves installing a header spool in accordancewith the invention on the well before a wellhead is installed and performing the steps required to perforate the casing and stimulate or fracture the zones requiring treatment in order to prepare the well for production before wellhead equipment is installed. This method and apparatus permits a well to be completed at a significantly less cost than for completing a multi-zone well in the traditional manner of completing after the wellhead equipment is installed.
