Patent CA-2159019-A1 (CA)
Title: A windtrap for power development
Inventor: WHELAN MATTHEW P
IPC: F03D9/00
Filed: 1995-09-25
Abstract: This invention relates to windpower and is titled "A Windtrap For Power Development". It is designed to take power from the wind by turning a vertical mast. The intention is to hold the total wind force that comes within the dimensional area of each unit when the said unit comes to the power side, then have the trap automatically close and feather the wind on the return side of the revolving mast. Feathering on the return side is assisted by:   a) a cable from a wing arm to the top side frame of the trap to hold same horizontal when on the return side, and b) two torsion springs on each unit attached, one to each end of the lower side frame of trap. The springs must carry 60% to 70 % of weight of the lower trap side section. Torsion helps wind lift the lower side towards the horizontal on the return side of mast and leaves 30% to 40% of the weight so gravity cam open it again on the power side. A partial balance is set by the torsion springs, between gravity, the trap design and wind force, to give continuous opening and closing, with the trap holding full wind force on power side and giving minimum resistance on return side.

Patent CA-2169646-A1 (CA)
Inventor: PADOVANI ROBERTO
IPC: H04B7/26
Filed: 1995-07-21
Abstract: A method and apparatus for matching the location of the forward link handoff boundary to the reverse link handoff boundary. A system constant is chosen which defines the product of the received power and the transmitted pilot power at every base station. The reverse link power level is measured at the base station and the forward link power level is compensated for the reverse link loading to maintain the constant product. Thereby the forward link handoff boundary to the reverse link handoff boundary are aligned to the same location.

Abstract: Oil and water based drilling muds, together with other wellbore contaminants such as pipe thread sealants and lubricants are displaced from the well (10) and the wellbore surfaces are cleaned by a system of four serially pumped fluid pills. The first stage fluid pill is a weighted spacer having an alkyl polyglycoside surfactant, a dispersant, a weighting agent and a viscosifier. The second stage pill is a drive fluid formed by water and a viscous polymer gel such as clarified xanthan gum having a viscosity/shear rate characteristic which minimizes mixing of the drive fluid pill with the displacement fluid pill. A buffer fluid pill comprising completion brine is interposed between the drive fluid pill and a fourth stage comprising a wash fluid pill using an organic solvent or a caustic alkyl polyglycoside as a final cleaning stage. The densities of the pills are controlled to minimize mixing and fingering.

Title: Air treating device having a bellows compressor
Inventor: MCCAUSLAND ROBERT
IPC: F04B45/027
Filed: 1995-02-17
Abstract: An air treating device having a bellows box in which is mounted a bellows compressor formed of two spaced apart diaphragms having memory-shaped metal alloy elements embedded therein. The diaphragms are caused to contract and expand by selective heating of the memory-shaped metal alloy elements. The bellows compressor is supported spaced in the bellows box whereby air can flow through the box and as the bellows expand the air in the box is cooled and expelled. As the diaphragms of the bellows compressor contract, more air is sucked into the bellows box and at the same time the refrigerant fluid inside the bellows is expelled into a condenser where it is condensed to liquid.      When the refrigerant liquid enters into the bellows it is vaporized and cools the bellows walls in their expanded state and the diaphragms act as a heat exchanger to cool air in said bellows box and expel it therefrom.

Patent CA-2195287-A1 (CA)
Inventor: FUJIMURA TAKASHI
IPC: C21D1/84
Filed: 1997-01-16
Abstract: It is an object of the invention to provide a solid railway wheel and a method of manufacturing the wheel which satisfies both of wear resistance and heat-crack resistance good for use in a high-speed railway vehicle.      In the wheel of the invention, the chemical composition of a base steel comprises: 0.4% to 0.75%C; 0.4% to 0.95%Si; 0.6% to 1.2%Mn; and less than 0.2%Cr. Especially, the content of Cr is preferably 0.05% to less than 0.2% and more preferably 0.07% to less than 0.15%.  It is characterized in that the wheel has pearlitic structure in a region of at least 50 mm in depth from the tread surface of the wheel.      Since the relatively high Si content and the relatively low Cr content are combined, the base steel has proper hardenability as a steel for a wheel. Therefore, the stable pearlitic structure, in which hardness is high and uniform and structure does not change even when heat is generated by application of the brakes, can be formed in a wide region such as a region from the tread surface to a depth of 50 mm or deeper.      The method of manufacturing the wheel of the invention is characterized by combination of the chemical composition of the base steel and a quenching process to the tread portion of the wheel. That is, when the tread of the wheel made of the steel of the above chemical composition is quenched, for example, the following cooling process is used. An operation to interrupt or weaken a cooling operation is performed at a stage before the temperature of the tread of the wheel drops to a pearlitic transformation start temperature in a continuous cooling transformation curve diagram. Thus, the pearlitic structure can be obtained without causing martensitic or bainitic transformation. The wheel having the pearlitic structure can be stably manufactured with good productivity in a commercial scale.

Abstract: A procedure and an arrangement for improved digital radio communication in a satellite-supported VSAT network (1) consisting of a plurality of VSAT subscribers stations (3, 4) and at least one central station or hub (2) are described.          Both the procedure and the arrangement relate to VSAT systems that provide for speech, image, and data communication within networks consisting of at least one central station or hub (2) and VSAT stations (3, 4) by way of a satellite (5). The hub (2) sends its information over at least one of its ground stations (6, 7) to the VSAT stations (3, 4) and receives the information sent from the VSAT stations on other frequencies.          Transmission frequencies and permissible overall data rates are determined by the hub (2) as a function of the propagation conditions that exist on the individual satellite links. The subscriber traffic is classified as either time-critical traffic (ZKV) and non-time critical traffic (ZW). A hub (2) consists of two or more fixed ground stations or diversity stations (6,) that are linked to each other, the traffic passing in each instance through the ground or diversity station (6, 7) that is the least affected by propagation effects and by breakdowns of system components. The central station or hub (2) assigns a secure frequency at which higher transmission quality is achieved because of smaller intermodulation interference to the individual subscribers on demand, this allocation relating to a narrow-band transmission channel over which telephone traffic can be passed between two subscribers, thereby avoiding a double hop. The system consists of a VSAT network (1) a central station or hub (2), a plurality of VSAT stations (3a, 3b, 4a, 4b) and a satellite (5). The stations (3, 4) transmit on the transmission frequencies specified from the hub (2), using the transmission parameters such as overall data rate, block length, and error protection procedure that are required. These parameters are either read out from a table in memory or determined by a dynamic procedure that matches the boundary conditions of the special network configuration. A specific control program that can optionally be implemented on the station computer (8) of the hub (2) is appended in the form of a flow diagram as an example.

Abstract: Masterbatches comprising high density polyethylene (HDPE) are used for the production of polyolefin articles, particularly films.  Employing HDPE in a masterbatch alone or in combination with a hydrocarbon resin and/or a polyolefin ultimately results in extruded polyolefin articles of optimal stiffness and ductility.  Employing a high density polyethylene in combination with a hydrocarbon resin and a polyolefin in a masterbatch causes the masterbatch to solidify more rapidly and be pelletized more efficiently.
