Title: Redundant pressurizing valve
Inventor: ALDERFER RONALD RAY
IPC: G05D16/10
Filed: 1993-12-03
Abstract: A pressurizing valve having a housing with a bore therein for retaining concentric first and second pistons within a sleeve having an end wall with an entrance port connected to a first conduit. A spring within the bore urges a first face on the first piston toward a first seat which surrounds the entrance port and a second face on the second piston toward a second seat surrounding an annular opening in the first piston. The fluid pressure in the first conduit acts on the first face to overcome the spring and move the first piston away from the entrance port to allow fluid to flow to an exit port in the housing. This type flow continues until such time that the first piston fails to move when the fluid pressure thereafter acts on the second face to move the second piston and allow the fluid to flow to the exit by way of the annular opening and a plurality of axial opening in the first piston to maintain the fluid pressure in the first conduit substantially constant. <IMAGE>

Title: Protective bellows for steering mechanism
Inventor: BREHERET JOOL
IPC: F16L35/00
Filed: 1994-02-24
Abstract: A protective bellows (28) is disclosed for protecting the axially movable rod (18) of a steering mechanism which has an angularly movable rod end (22). The bellows has a fixing collar (30) attached to the end of a casing (17) from which the steering rod (18) axially extends, and another fixing collar (32) clamped to the rod end (22). Bellows turns (28A...28N) extend between these fixing collars (30, 32) but are interrupted by an integral substantially cylindrical skirt portion (34) which is sized to make contact with the outside of the joint (26) connecting the rod end (22) to the steering rod (18). The skirt portion (34) ensures that the bellows turns are substantially undistorted by large angular movement of the rod end (22). Adjacent bellows turns (e.g. 28A, 28B) have different cross-sectional sizes so that their peaks and troughs have different diameters. This reduces the compressive forces acting between adjacent turns when the bellows is compressed by sliding of the steering rod (18). <IMAGE>

Title: Control of electromagnetic emissioins in battery backed apparatus
Inventor: DALE MARK JAMES CHARLES
IPC: H02J9/02
Filed: 1995-07-31
Abstract: In a battery backed electrically powered apparatus, a non-switched mains supply input 10 is connected through a filter 32 to a battery charger 34 to charge the backup battery 14, the filter 32 preventing electrical noise from the apparatus being conducted into the mains supply at input 10. An operational part of the apparatus, particularly an emergency light 8, can be powered from a switched mains input 12 during normal use. A switching circuit 20, 22, 24, 26, 28 is operable to connect the battery 14 to power the light 8 in the event of mains failure, and in this state the switching circuit breaks all electrical connection to the switched mains input 12. This arrangement allows for a total absence of noise filtration between the apparatus and the switched mains input 12. The lamp 8 may be an incandescent lamp. Alternatively, the lamp 8 may be a fluorescent lamp operated from the mains input 12 via a ballast 18 and operated from the battery 14 via a high frequency inverter 30. The switching circuit is in the form of a relay 20 with changeover contacts 22, 24, 26, 28 which not only completely disconnect the lamp 8 from the mains input 12 on mains failure, but also disconnect the ballast 18 from input 12 and from inverter 30 in this state, thereby avoiding the possibility that an electronic ballast 18 is damaged by becoming connected to the output of inverter 30.

Title: Electrostatically charged filter
Inventor: SEO HIROFUMI
IPC: B01D15/00
Filed: 1995-09-28
Abstract: A method and apparatus for separating heavy metal ions from a processing solution includes a filter. A cylindrical separating member divides the filter into two discrete compartments, an inner cylindrical portion and an outer annular portion concentrically arranged outside the inner cylindrical portion. The separating member is made of chemical and heat resistant material. The processing solution is made to flow through the inner portion in one direction and a gas is made to flow through the outer portion in the opposite direction. The flowing has negatively charges the separating member, which results in formation of an electrical double layer on the surface where the processing solution contacts the separating member. The heavy metal ions in the processing solution, which ions are positively charged, are attracted and adsorbed to the negatively charged separating member, thus removing the heavy metal ions from the processing solution.

Title: Process for treating a waste material
Inventor: GOLLEY CHRISTOPHER ROBIN LANGD
IPC: B01D21/02
Filed: 1996-08-14
Abstract: A dilute aqueous suspension of solid particulate material, comprising waste material from a process for recovering petroleum from oil sand, using e.g. an alkaline solution, is treated by diluting the gel-like suspension left after the coarse particles have settled out with at least 75%, preferably 100-500%, of its own volume of water to increase the settling rate of the particulate material and allow it to form a concentrated solid sediment. The dilution may be carried out by passing the gel-like suspension to a further storage pond or lagoon 2, to which fresh water is added to produce the required dilution. The water from which the sediment is separated may be returned to the system for recovering petroleum from the sand. The sediment may then be extracted from the pond, and transferred to a separation vessel 14 in which it is fractionated into coarse and fine fractions. The fractions, which may contain at least 40% by weight of kaolinitic clay, may be further treated by calcining in a kiln 21 to form a pozzolanic material. The pozzolanic material produced by the method is also claimed.

Title: A method of installing and aligning an antenna using an adjustable mount
Inventor: EDWARDS KEITH RUSSELL
IPC: H01Q3/08
Filed: 1997-05-16
Abstract: An antenna for a fixed wireless access (wireless local loop) system is installed at a subscriber's premises for communication with a base station by determining the absolute position of the premises using a GPS receiver and determining the position relative to the absolute position of a selected base station. The required azimuthal and elevation orientation data for the antenna is then determined by computer taking into account the heights of the base station and antenna mount. A base station providing the best signal is selected using a computer and GPS receiver to establish the closest base stations and their compass bearings. A compass is then used to locate the signal directions so that a measuring device can establish the strongest direct signal. An adjustable antenna mount having graded adjusting pivots (or a lockable ball joint) is attached to the premises and referenced to magnetic north before being positioned according to the orientation data. Fine adjustment can be made with micrometer adjusters and a meter to determine the best received signal.

Title: Method of forming a thin film transistor electrode with a tapered edge
Inventor: PARK YONG-SEOK
IPC: G03F1/00
Filed: 1997-06-02
Abstract: A mask with a line and space pattern 150 whose space width is smaller than the resolution of the exposure system is used to pattern a photoresist layer formed over a metal layer which is used for forming the drain electrode of a thin film transistor. The photoresist pattern is only partially exposed around the edges of the pattern and after development corrugations are formed at the edges of the photoresist pattern. The photoresist pattern is used to mask the metal layer during etching to form the drain electrode and the metal layer beneath the corrugated photoresist pattern is partially etched during drain electrode formation. The drain electrode produced by the etching has a tapered sidewall profile at the position corresponding to the corrugations in the photoresist etch mask. The tapered sidewall profile reduces step coverage problems such as crack formation in the passivation layer formed over the drain electrode.
