Patent CA-2124552-A1 (CA)
Title: Method of operating a hydraulic load sensing system
Inventor: TSCHIDA DONALD W
IPC: F04B49/08
Filed: 1994-05-27
Abstract: Abstract of the Disclosure An improvement in and method of operating a load sens-ing system in which a variable displacement, pressure com-pensated pump delivering hydraulic fluid to a fluid operat-ing device through a directional control valve is con-trolled by a load-sensing system pressure limiter which is set so that the system operates at the maximum continuous system operating pressure.  By also setting pump destroke pressure slightly higher than the necessary operating pres-sure for the load, optimum performance of the pump is rea-lized.  The load-sensing system pressure limiter is con-figured as a poppet which is placed inside of the body of the directional control valve and is biased by an adjust-able spring force to the closed position.  Preferably, the poppet connects the load sensing core of the directional control valve to an exhaust passage therein so as to re-quire  minimal  modification  of  the  directional  control valve.  In a preferred embodiment, the poppet has a bleed-down orifice extending therethrough to unload the load pressure signal when work has been completed or diminished.

Title: Assembly intended to manufacture a series of individual envelopes
Inventor: JUTEAU OLIVIER
IPC: B65D27/08
Filed: 1995-01-31
Abstract: The envelopes are obtained by folding and gluing individual sheets including three panels bearing patches of reusable glue on their rear face.  The assembly is prepared at the printer's, then sent out to a first user, which may be a processing laboratory in the case of envelopes for sending out photographic films.  The first user, possibly taking advantage of the fact that he receives a strip which has not been cut up, can mark on this strip the inscriptions which he desires, with the aid of a high-speed printer.  After that, the leaves may be separated, if they are still attached, and packaged into envelopes before or after being dispatched to a second user, who may be the photographer.  The sheets may constitute a continuous strip, or a stack of sheets arranged flat.

Title: Rail fastening apparatus
Inventor: IGWEMEZIE JUDE O
IPC: E01B3/16
Filed: 1995-03-06
Abstract: A rail fastening apparatus comprises a shoulder member engaging on a side of the rail flange and a rail clip in the form of a resilient bent rod.  The rod has limb portions that in the installed position extend transversely of the rail and inner and outer portions adapted to bear on the rail flange and on a bearing surface laterally outwardly of the rail, respectively.  The bent rod is generally symmetrical about a vertical plane transverse of the rail, and the limb portions comprise an upper pair and a lower pair.  The shoulder member has a reaction surface engaging one of the pairs of limb portions when displaced relative to the shoulder member as a result of upward pressure exerted by said rail flange and displacing this pair into contact with the other pair.  This provides a load bearing cross section of increased depth providing increased strength and bending stiffness.

Title: Catalytic converter for the catalytic treatment of exhaust gas
Inventor: STEENACKERS PIETER D
IPC: F01N13/04
Filed: 1995-04-10
Abstract: The catalytic converter for the catalytic treatment of exhaust gas has a housing, an inlet and an outlet.  The housing contains catalyst means having at least two packets of sheet metal members. The inlet leads into an inner cavity located between the packets and has, at its orifice, the same cross-sectional shape and the same cross-sectional dimensions as the inner cavity.  The latter has at least one free region whose cross-sectional area decreases in a direction away from the inlet.  The outlet is connected to an outer cavity located between inner surface sections of the housing and the catalyst means.  Each packet of sheet metal members bounds passages which in cross-section run from the inner cavity to the outer cavity on different sides.  This makes it possible to adapt the shape of the housing well to the available space.  In addition, the catalytic converter has advantageous flow and cold-start characteristics and can be economically produced.

Title: Process for treatment of volcanic igneous rocks to recover gold, silver and platinum
Inventor: BURR LYNN E
IPC: C22B11/02
Filed: 1995-06-27
Abstract: The recovery of gold, silver and platinum group metals from volcanic cinders containing iron is achieved by mixing the cinders with a suitable flux, and metallic copper, and smelting the mixture at a sufficiently high temperature to produce a molten mass of metal containing iron and copper, and a molten slag. The molten slag is separated from the molten metal mass by a suitable means. The slag is discarded and the metal mixture is cooled to a solid state. The copper and iron are then dissolved in acid, leaving an undissolved portion which can then be separated from the resulting leach liquor by filtration. Alternatively, the iron and copper bearing metal can be cast into an anode and electrolyzed in a sulfuric acid solution where copper is deposited at the cathode and iron is put into solution as iron sulfate. The insoluble residue at the anode can be recovered from the sulfuric acid solution by filtration. The filtered solids from either acid dissolution or electrolysis contain a significant amount of the gold, silver, and platinum group metals that were present in the original ore. These solids can then be processed by well known technology to recover their gold, silver, and platinum group metal content in essentially pure form. The solution which contains most of the silver can be treated by conventional means to recover that metal. With electrolysis copper is recovered as a cathode deposit. With acid dissolution copper can be recovered by other conventional methods. With either method copper can be recycled to the process.

Title: Exhaust filter backpressure indicator
Inventor: FUCHS ERVIN P
IPC: F01N9/00
Filed: 1993-09-02
Abstract: An exhaust filter backpressure indicator (10) includes a sensor (12) for measuring the backpressure of the exhaust system. The sensor sends a signal which is processed for indicating that an exhaust filter element is filled. The indicator includes a timer (24) so that a signal corresponding to pressure must be maintained for a predetermined period of time before the filled element is indicated. The apparatus may also include high and low frequency discriminators to process signals within predetermined signal frequency ranges corresponding to engine operating speeds. Therefore, depending on the operation of the vehicle, the element will be indicated as being filled at either high engine speed operation or low engine speed operation.
