Patent NO-161629-C (NO)
Inventor: BISSOT THOMAS CHARLES
IPC: C08J5/22
Filed: 1982-01-15
Abstract: An ion exchange membrane comprises a layer of fluorinated polymer which has carboxylic functional groups, a layer of fluorinated polymer which has sulfonic and/or carboxylic functional groups at a surface layer and a web of support material therein, and has channels in the membrane which extend from window areas of the membrane to blind areas of the membrane occluded by reinforcing members of the support material. The ion exchange membrane is derived from a precursor membrane which contains both reinforcing members and sacrificial members. The ion exchange membrane can be used to separate the compartments of a chloralkali cell, and such a cell operates at low voltage, high current efficiency, and low power consumption.

Abstract: In method and apparatus for producing a coherent stream of high velocity abrasive laden liquid, the method includes allowing particles of abrasive to assume the direction and velocity of a high velocity jet (22) of liquid. The method allows concentration of particles in the centre of the flow of liquid to reduce nozzle wear and increase cutting efficiency. The apparatus includes a nozzle (21) having a converging section (26, 27) attached to a straight section (28) that is sufficiently large that the abrasive particles approach the velocity of the fluid jet before leaving the exit (29) of the nozzle.

Abstract: The externally insulated window mounting is employed in the sidewall frame of a railway passenger carriage. This carriage frame comprises sidewall sections and post sections (10), an exchangeable outer skin and in between an insulating material. The window mounting is releasably secured to the sidewall sections and post sections. The inner frame, made up of at least four extrusion pieces spaced from the region of the window corners, features a lip which serves as a sealing surface for the outer skin and holds in place an outer, peripheral frame with undercut groove. A lip on the outer frame pointing away from the window opening, clamps the outer skin securely and holds in place a mounting strip of weather resistant, elastic material to retain the window glazing in place.

Abstract: In   the   V  belt   type   continuously   variable transmission,  after  the  output power from  the  prime mover  has been transmitted to the input  pulley  shaft, two paths are operable to transmit the output power from the input pulley shaft to the output pulley  shaft,  two paths  which are a main power transmitting path  through the 2-way differential clutch.   The drive ratio of  the sub power transmitting path is set in a slightly smaller value  than  the maximum drive ratio of the  main  power transmitting path.   When the movable input half  pulley of the input pulley has been moved near the position  of the  maximum drive ratio in the main power  transmitting path,  the rotational speed of the output gear in the 2-way  differential clutch become slower than that of  the input gear,  and as a result a rotational force is given to  the output gear so that the output pulley  shaft  is rotated  through  the  sub power  transmitting  path  in addition to the main power transmitting path so that  it becomes   possible   to  increase  driving   power   and accelerating force and also to decrease load to be added to the V belt.

Granted: 1994-05-03
Abstract: Abstract The functions of two virtual operating systems (e.g., S/370 VM, VSE or IX370 and S/88 OS) are merged into one physical system. Partner pairs of S/88 processors run the S/88 OS and handle the fault tolerant and single system image aspects of the system.  One or more partner pairs of S/370 processors are coupled to corresponding S/88 processors directly and through the S/88 bus. Each S/370 processor is allocated from 1 to 16 megabytes of contiguous storage from the S/88 main storage.  Each S/370 virtual operating system thinks its memory allocation starts at address 0, and it manages its memory through normal S/370 dynamic memory allocation and paging techniques.  The S/370 is limit checked to prevent the S/370 from accessing S/88 memory space.  The S/88 Operating System is the master over all system hardware and I/O devices.  The S/88 processors access the S/370 address space in direct response to a S/88 application program so that the S/88 may move I/O data into the S/370 I/O buffers and process the S/370 I/O operations.  The S/83 and S/370 peer processor pairs execute their respective Operating Systems in a single system environment without significant rewriting of either operating system.  Neither operating system is aware of the other operating system nor the other processor pairs.

Abstract: A block of composite material includes a dielectric material with a dielectric constant of ~ d = 4.66 and which is at least 4 µm thick and has electrically conductive microparticles randomly distributed throughout.  The composite material exhibits an optical bistability without cavity feedback.  The microparticles must be nearly uniform in size and of spherical diameter much smaller than the wavelength of light in the particle.  The composite, when illuminated by laser light in the range of 500 nm and of varying intensity, becomes opaque at a critical input intensity and stays opaque until the input intensity reaches a certain level both below and above the intensity at which it initially became opaque.  Thus the material behaves as an optical switch and a limiter.

Title: Apparatus for screening to remove knots from a fluid borne slurry of fibers and knots
Inventor: YOUNG DOUGLAS L G
IPC: B07B1/24
Filed: 1991-10-21
Granted: 1996-04-02
Abstract: A screening apparatus removes a fluid borne pulp fiber slurry from knots which have been concentrated from a pulp processing stream.  A rotating radially symmetrical screen provides centrifugal screening to accept a pulp fiber slurry while an integrally connected spiral flight conveyor transports knots from the inner surface of the screen to a knot discharge chamber located axially above the screening chamber.  Above the screening chamber but below the liquid level in the housing, a fiber free wash liquor is provided through a tangentially oriented nozzle in the direction of rotation of the spiral flight conveyor to release fibers from the knot surfaces thereby enabling them to pass through the screen.          The screening apparatus also provides for removal of heavy tramp materials, for maintaining liquid level control, for minimizing air entrainment and foam formation, and for preventing clogging of the screen apertures and knot discharge outlet.

Inventor: SCHAFER CHRISTOPHER E
IPC: G07B3/04
Filed: 1991-12-16
Granted: 1996-01-02
Abstract: The disclosure is of a stacked structure made up of a plurality of identical box-like units arranged one atop the other in a near vertical array in which each unit presents a front face angled to the vertical in such fashion that the front face of each unit forms a dihedral angle with its next lower and next upper unit. Each unit has a floor and a roof that diverge rearwardly relative to each other which causes each upward unit, resting via its floor on the roof of the next lower unit, to tilt forwardly so that its front face is at a lesser angle to the vertical than the angle between the front face of the next lower unit and the vertical.  The configuration is such that the increments by which the angles decrease from bottom to top are equal.  The units are basically transparent to expose the unit contents and each unit has a dispensing means in its rear part.
