Patent CA-2149857-A1 (CA)
Title: Process for the preparation of metal hydroxide
Inventor: NAUMANN DIRK
IPC: C25B1/00
Filed: 1995-05-19
Abstract: Process for the preparation of metal hydroxides and/or metal oxides/hydroxides from corresponding metal ions and hydroxide ions, whereby the metal ions are formed in an electrochemical membrane process in which the metal ions are formed by anodic dissolution of corresponding metals in the anode compartment and the hydroxide ions by cathodic reduction of water in the cathode compartmentseparated by an anion-exchange membrane, and the hydroxide ions are transferred through the anion-exchange membrane into the anode compartment under the driving force of an electric field.

Title: Process and Apparatus for Producing Heat Treatment Atmospheres
Inventor: VAN DEN SYPE JAAK STEFAAN
IPC: B01J23/46
Filed: 1995-06-05
Abstract: An  endogenerator  is provided  in which  CO  and H2 are generated as primary products of hydrocarbon oxidation. Noble  metal  catalysts  such  as  platinum  (Pt)   and particularly rhodium (Rh), are loaded on a porous ceramic support,  of  example,  an  alumina  carrier.    In  the endogenerator reactor little or no CO and H2 are produced by the slow and energy-intensive reforming reactions and this  allows  for  a  compact  reactor  which  operates autothermally without auxiliary heating means, and with high space velocities wherein space velocity is defined as the number of standard cubic feet per hour of output gas per  cubic  foot  of  the  catalyst  carrier.    Preferred hydrocarbons are methane or propane, preferred oxidants are nitrogen/oxygen mixtures with from 5% oxygen up to 100% oxygen.    The  endogenerator  of  the  present  invention provides  a  process  and  apparatus  that  generates  the required  reducing  gases  CO  and  H2  for  heat  treating applications which require leaner atmospheres and lower carbon potentials.    The present  invention  provides  a reactor which operates autothermally and in which very high space velocities are achieved.  The reactors of the present invention also provide inexpensively the reducing elements required to obtain buffered atmospheres in heat treating furnaces and thereby allow the introduction of inexpensive nitrogen produced by membranes or PSA into such furnaces.

Title: Packet switching system enabling a source node to confirm a receipt of a cell by a destination
Inventor: ISAKA MASAZUMI
IPC: H04L47/43
Filed: 1995-07-28
Abstract: In a packet switching system, a source node divides a variable length packet into a plurality of cells having a predetermined length, and sequentially sends the cells toward a destination node via a first bus controller accommodating the source node, an ATM (Asynchronous Transfer Mode) switch, and a second bus controller accommodating the destination node. The second bus controller detects and stores the last cell from the . source node. T h e destination node generates receive response data for every incoming cell by hardware control to show whether or not the cell has been normally received, and returns the response data to the second bus controller. In response, the second bus controller generates a response cell by hardware control and returns it to the source node via the ATM switch and first bus controller. This allows the source node to determine rapidly whether or not the receipt at the destination node is normal cell by cell.

Filed: 1995-08-18
Abstract: A suspend/resume computer system having a-CPU,  a non-volatile storage device, volatile registers and memory data, a power management processor, a backup suspend timer and a power  supply in circuit communication.  The power management processor controls the regulation of power to the CPU by the power supply.  The suspend/resume system is controlled by an operating system having power management control.  The backup suspend timer executes independently of the power management portion of the operating system.  The backup suspend timer causes the system to suspend if the power management portion of the operating system ceases functioning and the system should otherwise be suspended.

IPC: A01J25/11
Filed: 1996-09-05
Abstract: Multiple columns of cheese curd are simultaneously compressed and cut into blocks of cheese by feeding curd into the top perforated tubular linings hanging freely within hollow towers, all towers positioned on a single, enclosed sanitary housing. A negative pressure is maintained in each tower to draw curd into the tower. Each pillar of curd is supported by a single guillotine blade closing off the bottom of all the towers and located within the sanitary housing. Each perforated, freely hanging lining is spaced apart from the wall of its tower to form a drainage passage for whey pressed out from the curd by the weight of the superimposed pillar. The guillotine blade is then withdrawn and each pillar of curd is lowered by an elevator into a cheese form positioned below each tower and within the housing. The guillotine blade is then returned to its closed position, so as to cut off a block of curd from each pillar. The direction of each elevator is then reversed, causing each block of cheese to be pressed up against the bottom of the guillotine blade and out against the sides of its cheese form. Once each cheese block has been compressed, each elevator is withdrawn, leaving each cheese block remaining in its form. Each form is then rotated to a substantially horizontal position and each cheese block is then ejected into a bag being held by a bagging device located adjacent each cheese form. The bagged blocks of cheese are then released from the bagging device for transport to a processing station.

Title: Use of phosphonylmethoxyalkyl nucleosides for the treatment of raised intraocular pressure
Inventor: FREEMAN WILLIAM R
IPC: A61P27/06
Filed: 1995-03-31
Abstract: Methods for treatment of conditions of abnormally increased intraocular pressure, particularly those caused by glaucoma, by administration of phosphonylmethoxyalkyl nucleoside analogs are provided. Compositions formulated and packaged for intraocular administration for use in the methods are also provided. Administration of the compound may be by intravitreal injection, aqueous humor injection, injection into the external layers of the eye, such as subconjunctival injection or subtenon injection, or may be, when penetrating derivatives are used, by topical application to the eye. The degree of reduction in pressure is dosage-dependent, and significant reduction in pressure is obtained. A single injection can produce prolonged, and perhaps permanent, lowering of the intraocular pressure.

IPC: A61B18/00
Filed: 1996-10-09
Abstract: A selectively positionable fluid conduit for gas removal from or gas introduction to a specific environment is disclosed.  The fluid conduit includes a tubular wand having an orifice at the distal end thereof.  Unwanted gases are removed by suction force through the orifice.  Desirable or therapeutic gases are introduced to a specific location through the orifice.  The tubular wand is coupled to a malleable positioning tube.  The malleable positioning tube can be manipulated into various configurations such that the positioning tube maintains the last chosen configuration.  In one disclosed embodiment, the malleable positioning tube includes tubular bellows formed from a plurality of alternating large and small diameter rings joined by frusto-conical walls. In another embodiment, the malleable positioning tube includes a malleable wire associated with a semi-rigid tube.

The malleable positioning tube is in gaseous communication with either a gas evacuator or to a pressurized gas source.  In one disclosed embodiment, a flexible tube is used to connect the malleable positioning tube to a gas evacuator or gas source.

Abstract: It is known that when drilling a hole you first have to measure for the exact center and hand punch it before drilling.  Whether it be a handyman or trade's man one cannot drill a straight hole with an electric or battery hand drill in any way.  The difference from one side to the other will be noticeable especially so in thick material, it could be by more than 1/8" inch off.        With this invention you will illiminate these difficulties by using the specifically marked base for centering then for drilling use one of the five different sizes of the screw-in bushing guides in the holes already made on this same base, wherever it is most convenient for you to drill.          All in all one does not have to center punch the hole before drilling and with the guides provided one can be assured that the drilling will be precise.
