Title: Hydraulic valve
Inventor: DE PIERI TIMOTHY
IPC: F16K31/24
Filed: 1994-09-15
Abstract: The present invention discloses a valve which utilises an unbalance of flow induced pressure forces to keep the valve open or closed. The valve has an interior cavity (15) into which an opposite and aligned inlet (12) and outlet (13) open. A bulbous body (16) is located within the cavity and is reciprocally mounted on a spindle (17) which passes through the outlet. Movement of the body increases the flow area at one end of the body and decreases the flow area at the other end of the body.  In accordance with Bernoulli's theory this changes the pressures acting on the body (16) giving rise to a net force on the body. A cistern inlet valve (111, 211) and cistern (19) are also disclosed.

Filed: 1994-03-25
Abstract: A B S T R A C T      The present invention relates mainly to a wrapping method and to apparatus for implementing the method.  The invention provides a method of wrapping a palletized load, the method comprising a step of depositing one or more plastic films around the palletized load, thereby covering the palletized load and closing the inlets to the pallet, the method being characterized in that it includes a step that consists in disengaging permanent passages in the film where it obstructs the inlets of the pallet (2) for passing the forks of handling equipment. The present invention is particularly applicable to wrapping palletized loads.  A main application of the present invention lies in wrapping loads that are palletized on standard pallets.
Patent CA-2137943-A1 (CA)
Inventor: CHAN WAI Y C
IPC: A47L15/44
Filed: 1994-12-13
Abstract: A detergent dispenser controller for use with a washing device, such as a dishwasher, that measures detergent concentration in a water tank by measuring the conductivity of the detergent solution in the water tank. The detergent controller automatically learns the feed rate of the detergent dispenser used, regardless of the type of detergent dispenser being used. For each detergent feed cycle, the controller computes a Feed Factor equal to the amount of detergent feed on time required for each unit increase in the detergent concentration, which is the inverse of the detergent feed rate. The controller stores the computed Feed Factor for the last N feed cycles in a non-volatile memory, and computes a running average of the N feed factors stored in the non-volatile memory. Whenever the detergent dispenser is powered on, it determines the difference between the measured wash tank detergent concentration and a specified detergent concentration set point value. The computed average feed factor and the difference between the set point and the current detergent concentration are multiplied to compute a detergent feed on time. The detergent dispenser is then turned on for the computed feed on time, and after a suitable subsequent mixing period, the change in detergent concentration during the last feed cycle is determined and a new Feed Factor is computed and stored. The detergent concentration is preferably measured using logarithmic measurement units, and separate Feed Factors may be computed and used for at least two detergent concentration ranges.

Patent CA-2149271-A1 (CA)
Title: Improved process to prepare triorganotin lithium
Inventor: HERGENROTHER WILLIAM L
IPC: C08F36/04
Filed: 1995-05-12
Abstract: Solutions of triorganotin lithium are described having low residual concentrations (preferably less than 2,000 ppm) of halide.  These are produced by a two-step process.          Triorganotin halide is reacted with lithium to produce hexaorgano ditin and a precipitate of lithium halide.   The lithium halide precipitate is removed by filtration and/or use of highly concentrated reaction conditions.  Then the hexaorgano ditin is further reacted with  lithium  to  form  the  triorgano  substituted  tin lithium.   The  lithium halide is  less soluble  in hot tetrahydrofuran (THF) and/or more concentrated solutions. THF is a preferred solvent for the reaction.   The low-temperature reactions described result in low amounts of inactive and/or undesirable byproducts. These triorganotin lithium compounds are useful as anionic initiators that result in polymers with terminal tin compounds,  e.g., triorganotin, attached to the terminal end of the polymer where initiation occurred.  The polymers with terminal tin compounds have lower hysteresis in cured carbon black-filled  elastomeric  compounds.    Low concentrations  of residual halides in the initiators and consequently in the polymers has been associated with reduced amounts of volatile  organotin  compounds  being  generated  during processing of polymers with organotin terminal groups.

Inventor: SANTINI HUGO ALBERTO EMILIO
IPC: H01F10/26
Filed: 1995-07-28
Abstract: A thin film low profile write head is provided which has first and second pole pieces which are magnetically connected in a pole tip region and at a back gap. The pole tip region is located between the head surface and a zero throat height and the head has a body region which is located between the zero throat height and the back gap. A plurality of insulation layers are located above the first pole piece in the body region. Each of the insulation layers has an apex where the insulation layer commences and each insulation layer extends from its apex toward the back gap. The plurality of insulation layers typically includes first, second and third insulation layers. In the preferred embodiment the apex of the second insulation layer is located at and defines the zero throat height of the head. This enables a very narrow track width second pole tip to be constructed simultaneously with the second pole piece using ordinary photolithography processes. Further it enables the insulation layers, the coil layer and the second pole piece to be thinner than prior art layers.

Abstract: Composite materials formed from bone bioactive glass or ceramic fibers and structural fibers are disclosed. In pre-ferred embodiments, a braid or mesh of interwoven bone bioactive glass or ceramic fibers and structural fibers is im-pregnated with a polymeric material to provide a composite of suitable biocompatibility and structural integrity. Most preferably, the mesh or braid is designed so that the bioac-tive fibers are concentrated at the surface of the implant (200) to create a surface comprised of at lest 30 % bioactive material, thereby providing enhanced bone ingrowth. The interweaving between the bone bioactive glass or ceramic fibers and the core of structural fibers overcomes the prob-lems found in prior composite systems where the bioactive material delaminates from the polymer. Preferred bioactive materials include calcium phosphate ceramics and preferred structural fibers include carbon fibers. Improved prosthetic implants (200) and methods of affixing an implant (200, are thus also disclosed

Title: Cartridge utilizing a plurality of contact charging members
Inventor: REAM GREGORY LAWRENCE
IPC: G03G15/02
Filed: 1996-06-06
Abstract: Cartridge contains a brush charger and printer contains a charge roller.  Upon installation of the cartridge a top shutter is moved downward and the charge roller is moved by a pivoted arm through the opening left by the shutter to contact a photoconductor drum in the cartridge.  In operation the roller functions after charging by the brush at a potential to control the final charge on a photoconductor prior to xerographic imaging.  The precharging by the brush greatly reduces deterioration of the charge roller, permitting long machine life with the accurate and uniform operation of a charge roller.

Patent CA-2179727-A1 (CA)
Inventor: LEE GEORGE C
IPC: F16F15/02
Filed: 1995-01-27
Abstract: A method and apparatus for structural deflection control, as well as associated sequential controls that are based on new control laws. The apparatus of this invention is of relatively low cost and performs better than prior art devices. The essence of the invention is to adjust the dynamic parameters (mass, damping, stiffness coefficients of the structure and/or input forcing coefficients) adaptive to input dynamic loads, by using the new devices and the suggested control laws. In so doing, the structure performs an adaptive function to effectively counter tile effects induced by multi-directional external excitations. The required control power can be nil, or many times lower than prior art active control devices, and the effectiveness can be equivalent or even better than the current state-of-the-art active controls. The devices used by the apparatus of this invention can readily be manufactured for immediate application in structures, buildings and contents, and other constructed facilities.
