Patent CA-2040633-A1 (CA)
Inventor: LAMBERT BARNUM B
IPC: B01D53/04
Filed: 1991-04-17
Abstract: A disposable CO2 absorber for applications in rebreathing systems uses a flexible bag-like pouch to contain CO2 absorbent granules. The pouch includes an intake port having a one-way valve at the top of the pouch and an outlet or exhaust port including a perforated cylindrical tube or perforated disk in the bottom of the pouch. Exhaled gas containing CO2 passes through the one-way valve at the intake port and contacts the absorbent granules where a chemical reaction bonds the CO2 with the granules. The residual gas, substantially free of CO2, passes out of the pouch through the exhaust ports for rebreathing by the user. The flexure of the pouch increases the efficiency with which the CO2 is absorbed.

Title: Methods for measurement, analysis and assessment of ground structure
Inventor: TOKIMATSU KOJI
IPC: E02D1/02
Filed: 1991-04-23
Abstract: For determination of the laminar structure and other characteristics of a ground, oscillation sensors for detecting the vertical component or vertical and horizontal components of oscillations are disposed at three or more points within a comparatively small area at ground level to simultaneously measure microseisms at the respective points, if necessary with locations of said points being varied and measurements be performed at the respective locations and the vertical oscillation data or vertical and horizontal oscillation data thus generated are analyzed. This method not only permits an expedient, positive and accurate assessment of the laminar structure and other characteristics of the ground but also permits the measurement of ground structure even when the area available for measurement is small.

Title: Preparation of conjugated dienes
Inventor: HUDSON IAN D
IPC: C07C1/207
Filed: 1991-05-29
Abstract: ABSTRACT          The invention relates to a process for the preparation of a conjugated diene from the corresponding carbonyl compound having the same number of carbon atoms by dehydration at a temperature of 300° to 450°C using a catalyst comprising aluminium phosphate having the cristobalite structure.          This catalyst is superior to aluminium phosphate having the tridymite structure in the dehydration of carbonyl compounds and has advantages over boron phosphate catalysts.  Using the process, isoprene may be prepared from 2-methyl butanal and/or methyl isopropyl ketone in high yields.          Unexpectedly aluminium phosphate having the cristobalite structure is markedly superior to boron phosphate in converting methyl isopropyl ketone, which is an intermediate product formed in appreciable amounts in the dehydration of 2-methyl butanal to isoprene.  This superiority significantly improves the process economics of the conversion reaction of 2-methyl butanal to isoprene.

Title: Starter system for an internal combustion engine
Inventor: NAGASHIMA SHINICHI
IPC: F02N11/00
Filed: 1991-05-31
Abstract: In a starter system for an internal combustion engine using a planetary reduction gear unit, the internal gear of the planetary reduction gear unit, the center bracket accommodating the internal gear and the pinion cover are joined together so as not to rotate relative to one another by using radial projections provided in the outer circumferential surface of the internal gear which are passed through openings provided in the center bracket and received by associated recesses provided in the pinion cover.  The three members are thus prevented from rotating relative to one another with a simple structure which is also easy to assemble.  The projection of the internal gear may also be used for securing an annular seal member interposed between an axial end surface of the internal gear and the corresponding shoulder surface of the center bracket.

Title: Home financial transaction system
Inventor: GOROG WILLIAM F
IPC: G06Q20/00
Filed: 1991-11-01
Abstract: Abstract A Home Financial Transaction System  ("HFT")  is described comprising financial transaction terminals with means to read symbolic representations of data which identify merchant/service provider,  method  of  payment,  amount  of  payment  and  type  of transaction to be conducted.  The FTT user scans optical reader means over the symbolic representation on a bill or invoice and stores the information relating to the amount to be paid, method to be paid and related information in the memory of the FTT.  Once all transactions have been stored, the FTT communicates with a financial transaction computer system which assembles data from a plurality of FTTs for subsequent transmission to banks and other financial institutions for clearing house operations.   Symbolic representations can be imprinted on bills or invoices or imprinted on separate data sheets which can be scanned by an optical scanning means to input the desired identification data.  One enhancement also calls for transaction codes to be symbolically represented and input by the optical scanning means to conduct the desired transaction.

Title: Friction welder having an electromagnetic drive which produces orbital motion
Inventor: SNYDER EDWARD A
IPC: H02K33/00
Filed: 1991-12-18
Abstract: An electromagnetically actuated friction welder produces orbital motion at interfaces between parts (usually of thermoplastic material) to bond the parts by fusion generated by friction.  This welder can also be operated alternatively to produce reciprocating vibratory forces thereby providing flexibility as to the selection of an orbital or reciprocating mode, depending upon the joint to be welded.  The velocity of motion is controllable preferably around the resonant frequency of the driven structure by adjusting the frequency of the AC power which operates the electromagnetic drive motor of the welder.  A plate which carries one of the parts to be welded and which is driven is flexurally mounted for movement in an orbital plane or planes containing the interfaces without substantial tilting by an array of stiff members, such as rods, located around the drive motor, attached to the plate at one end and to a tubular structure at the opposite ends thereof.  The tubular structure is desirably attached to a massive support carried by the frame of the welder.

Title: Integrated helicopter enpennage structure
Inventor: WEINER STEVEN D
IPC: B64C27/82
Filed: 1991-12-20
Abstract: Abstract of the Disclosure INTEGRATED HELICOPTER EMPENNAGE STRUCTURE      An integrated empennage structure is provided for a helicopter embodying a ducted fan antitorque device.  The integrated empennage structure includes a shroud that houses the ducted fan antitorque device, a vertical stabilizer, and a horizontal stabilizer.  The aerodynamic configurations and/or orientations and the spatial orientations of the shroud, vertical stabilizer, and the horizontal stabilizer are interactively related and optimized to provide yaw stability and directional control and pitch stability and maneuverability required for helicopter flight operations.  The shroud is spatially orientated at a first predetermined cant angle with respect-to the vertical plane of symmetry of the helicopter fuselage such that the ducted fan antitorque device provides lateral antitorque thrust to counteract main rotor assembly induced torque and a positive vertical force component to enhance the overall lift capability of the helicopter.  The vertical stabilizer is spatially orientated at a second predetermined cant angle with respect to the vertical plane and aerodynamically configured with a predetermined camber and/or aerodynamically orientated with a predetermined angle of incidence to provide an antitorque force during forward flight regimes that allows the ducted fan antitorque device to be effectively off-loaded and a negative vertical force component that complements the negative vertical force provided by the horizontal stabilizer.  The aerodynamic functioning of the vertical stabilizer allows aerodynamic configuration and/or the aerodynamic orientation of the horizontal stabilizer to be reduced and facilitates the attachment of the horizontal stabilizer in substantially symmetrical relation to the vertical stabilizer.  The horizontal stabilizer is aerodynamically configured and orientated to optimize the dynamic pitch stability of the helicopter in the forward flight regimes.
