Title: Apparatus for heat treating successive charges
Inventor: BEURET PIERRE
IPC: C21D9/00
Filed: 1992-07-02
Granted: 1996-08-20
Abstract: The charging trolley (25) brings the charge and deposits it on the plug (10) of the oven (1). 
<??>The introduction of the charge into the oven (1) and its closure are performed by the action of the lift (12) which comes down again after the treatment to an intermediate position, from which the oven (1) can be moved horizontally, the lower belt (4) pushing the base grid of the charge onto the lid (17) and the tray (22) of the lift (18) placed in upper position. The lid (17) ensures that the oven opening is sealed against the gases for protecting the charge. 
<??>This lift makes it possible to introduce the charge into the quenching tank and then to return it into a draining position and to deposit it on the discharging trolley (38) travelling on the line (36, 37).

Title: Water supply pressure control apparatus
Inventor: YONNET CLAUDE
IPC: G05D16/20
Filed: 1993-06-08
Granted: 2005-08-09
Abstract: A fluid supply pressure control apparatus for use in conjunction with a pressure control valve (10) of a fluid supply system is disclosed which includes: first sensor means (26, 28) for sensing the pressure of the fluid at a first point (12, 14) in the system, and first control means (16) for controlling the pressure control valve (10) to adjust the pressure of the fluid at the first point in the system in accordance with a difference between the pressure sensor by the first sensor means and a predetermined pressure valve. The apparatus further includes second control means (24) for controlling the predetermined pressure value to reduce fluctuations in the fluid pressure at a second point in the system.      The aim of this apparatus is to maintain the lowest possible pressure in the supply pipes commensurate with maintaining a reasonable pressure in outlying and elevated areas and with meeting the demand for water.      This provides a means of controlling water supply pressure whereby water loss through leakage is likely to be substantially reduced.
Patent CA-2100842-C (CA)
Inventor: POIL JAMES E
IPC: A61F2/54
Filed: 1993-07-19
Granted: 1998-11-24
Abstract: A motion producing device in the form of a linear actuator, circular pump, or a robotic or prosthetic limb which functions to produce many kinds of useful work is provided.  The device includes a linear series of alternately spaced fixed and polarity reversible magnets.  The fixed and polarity reversible magnets may have more than one magnet assembled as a force unit of magnets of fixed polarity or reversible polarity which is surrounded by a rigid electrically insulating material and that carries rigid electrical conductors in the form of tubes.  Between each magnetic force unit is an elastic electrically insulating material allowing an expanding or shrinking of the distance between the magnetic force units in accordance with the polarity reversal of the reversible  magnetic force units.  The elastic expansion or contraction material carries flexible elastic tubes that connect up with the rigid tubes to hold a current carrying electrolyte to carry an electrical current from  a D.C. battery to the magnets when they are electromagnets.          Various types of guides are used to prevent lateral movement of the magnets.  A second embodiment also has magnetic force units of the fixed and reversible polarity type but has slideable electrical contacts in an external side guide and therefor requires no electrolyte or tubes.  A further modification utilizes the original rigid tubes and provides guide rods as slideable electrical contacts to slideabley engage the rigid tubes which are metal.  Again the disposing of the elastic flexible nonconductive tubes in the elastic nonconductive filler material between adjacent magnets is possible.

Title: Seed centering distribution system
Inventor: BOURGAULT GERARD F J
IPC: A01C7/20
Filed: 1993-12-16
Granted: 1998-10-13
Abstract: For use with an air seeder for distribution of seed to a agricultural implement by pneumatic conveyance is a unique seed-centering and distribution system.  The primary conveyance tube which is adapted to receive metered amounts of fertilizer and/or seed or granular herbicide is equipped with a plurality of internal sloped annular rings as well as a series of internal baffles.  The internal baffles are particularly adapted for dividing the seed stream through a right angled turn from the horizontal to the vertical.  The sloped annular rings project further into the conveyance tube on their downstream side than on the upstream side.          Interestingly enough, it has been found that much less power is required to center and evenly distribute the seed with this device than the prior art devices.  Moreover, damage to delicate seed is greatly reduced.

Abstract: The size range of particles separated on a stack of sieves (16a-16f) of different mesh sizes is measured automatically. The stack is clamped together and shaken as a unit to separate the respective fractions, following which the sieves are sequentially separated from the stack and inverted one at a time to dump the fraction retained on each, onto a scale (102). Each fraction is weighed separately and their relative proportions can be calculated automatically. In a preferred embodiment the sieves are individually cantilevered from a vertical conveyor (28). The sieves are inverted one by one to dump their contents by advancing them around a horizontal roll (32) at a lower end of the conveyor.

Abstract: Disclosed is a shock absorbing suspension system supporting a seat on a floor of a vehicle The suspension system includes a hydraulic bag filled with a liquid and coupled to support the seat on the floor, the hydraulic bag having an upper orifice. The suspension system also includes a reservoir partially filled with liquid, having a lower orifice, an upper orifice, and a baffle positioned adjacent the lower orifice to impede the liquid from escaping through the upper orifice. An adjustable valve supports the reservoir on the hydraulic bag and has an internal passageway communicating with the hydraulic bag via its upper orifice and the reservoir via its lower orifice to allow the liquid from the hydraulic bag to pass into the reservoir. The passageway is sufficiently small to dampen motion of the seat toward and away from the floor. The reservoir includes a supply of gas in direct communication with the liquid, the gas being compressed when the liquid enters the reservoir through the valve, thereby providing additional shock absorption. The reservoir is positioned above the hydraulic bag, such that gravity keeps the gas above the liquid and out of the valve without requiring a diaphragm to maintain gas/liquid separation.

Abstract: To prevent particular transmission equipment from artificially increasing low level audio signals to a predetermined allowable level, such signals are first summed with a stabilization signal having a predetermined frequency toform a composite audio signal. Moreover, the stabilization signal has a level that prevents any increase in signal level that may be artificially imposed on the composite signal during the processing of the composite signal by the transmission equipment. Once the composite signal has been so processed, then the stabilization signal is removed therefrom and the original audio signal is outputted to associated transmission media.
