Title: Analyzer for temperature sensitive colloidal mixtures
Inventor: GARVER THEODORE M
IPC: G01N21/31
Filed: 1998-09-18
Abstract: A method and apparatus for characterizing colloids by successive measurements of light attenuation or emission of a colloidal mixture at two or more temperatures and at one or more wavelengths. The difference or ratio of the measurements at two or more temperatures provides a measure of the colloidal stability with respect to temperature. The amount of certain organic colloids that are unstable to temperature variation may be determined from the magnitude of the measurement change. In appropriate mixtures, this method provides a means to distinguish components of colloidal substances based. This method may be specifically applied to determine the stability and concentration of colloidal pitch or wood resin in a pulp or paper process water. In this context it may be used to distinguish colloidal pitch or wood resin from talc, clay, carbon black or other fillers.

Patent CA-2305438-A1 (CA)
Title: Mechanically handling flowable material
Inventor: FARR KENNETH
IPC: B65D19/12
Filed: 1998-10-08
Abstract: A method of mechanically handling discrete material comprises loading onto a deckspaced pallet base having a frame surrounding downwardly-openable flaps, transporting the loaded base to a required location while supporting the flaps on the forks of a forklift truck, resting the frame on suitably spaced-apart members at the required location, and lowering the forks to permit the flaps to open for gravity discharge of the material. Two such flaps can be employed, but it is preferred to provide a pair of lower flaps with a limited angle of opening, and a pair of upper flaps disposed closely above the lower flaps, hinged at right angles to the lower flaps, and of such a tapered shape that their angle of opening is limited by the open position of the lower flaps. Alternatively, the angle of opening is limited by stops associated with the spaced-apart members on which the frame of the pallet base is rested for discharge. Thus the two pairs of flaps open to form a funnel-shaped material discharge chute.

Title: Message providing apparatus
Inventor: NAGATOMO HIDEO
IPC: G09F27/00
Filed: 2000-06-19
Abstract: A message providing apparatus according to one embodiment is apparently a small-sized (for sample, screen size of about 3.5 inches) flat display (for example, LCD), wherein a speaker is provided at a cabinet, and a memory card that is a message data storage medium is inserted into the cabinet.      Advertisement display data is stored to be classified into a moving image layer indicating a landscape, a still image layer indicating a commodity, a graphic (POP) layer indicating a price, a character layer indicating a catch phrase, and a sound layer which are displayed to be superimposed as required. BGM music data is also stored as the sound layer, and is reproduced in synchronism with a display.   Advertisement characters are printed at the cabinet.      When power is supplied, the apparatus automatically starts data reproduction of the memory card (by using a power on play function), and when all the data has been reproduced, the apparatus automatically restarts reproduction (by using an auto replay function). The message providing apparatus can be disposed on a commodity display shelf in place of a conventional advertisement providing apparatus so that image or sound information such as television commercial message popular among consumers can be distributed near commodities.
Patent CA-2314655-A1 (CA)
Inventor: CARTER JAY W JR
IPC: B64C27/02
Filed: 2000-07-26
Abstract: A rotor aircraft has an adjusting mechanism that controls the sensitivity of the control stick relative to fore and aft tilt of the rotor. The control stick is pivotable between fore and aft directions as well as laterally about a control stick pivot point. A rotor linkage is connected between the control stick and the rotor rotor head.  The rotor linkage assembly tilts the rotor head in response to tilting movement of the control stick. The linkage assembly has a control point that rotates at a radius about the control stick pivot point. An adjusting member located between the control stick and the linkage assembly can be moved to change the radius of the control point to the control stick pivot point. The change in radius corresponds to the amount of tilt that the rotor head make while the control stick moves between full aft and full forward positions. The control stick also controls ailerons and a horizontal stabilizer but these control services are not affected by the adjusting member.

Title: Augmentation of muscle contractility by biphasic stimulation
Inventor: MOWER MORTON M
IPC: A61N1/02
Filed: 1999-05-21
Abstract: Augmentation of electrical conduction and contractility by biphasic stimulation of muscle tissue. A first stimulation phase has a first phase polarity, amplitude, and duration. The first stimulation phase, which acts as a conditioning mechanism, is administered at no more than a maximum subthreshold amplitude. A second stimulation phase has a second polarity, amplitude, and duration. The two phases are applied sequentially. Contrary to current thought, anodal stimulation is applied as the first stimulation phase, followed by cathodal stimulation as the second stimulation phase. In this fashion, pulse conduction through muscle is improved, together with an increase in contractility. Furthermore, this mode of biphasic stimulation reduces the electrical energy required to elicit contraction. In addition, the conditioning first stimulation phase decreases the stimulation threshold by reducing the amount of electrical current required for the second stimulation phase to elicit contraction. The muscle tissue encompassed by the present invention includes skeletal (striated) muscle, cardiac muscle, and smooth muscle.

Title: Single-pipe cylindrical reformer and operation method therefor
Inventor: MIURA TOSHIYASU
IPC: H01M8/06
Filed: 2000-04-20
Abstract: A single-pipe cylinder type reformer produces a hydrogen-rich reformed gas by performing steam reforming for a reformation material gas such as town gas. A circular inner cylinder (3 or 68) is concentrically located inside an upright circular outer cylinder (1 or 10) forming the jacket of the reformer at a distance in the radial direction. Circular intermediate cylinders (2 or 60) are concentrically located between the outer cylinder and the inner cylinder at distances in the radial direction, respectively. A circular radiation cylinder (4 or 14) is concentrically located inside the inner cylinder at a distance in the radial direction. A burner (8 or 18) fixed to one end portion of the reformer in the axial direction to be located in the center of the radiation cylinder in the radial direction and a steam generator (34) are disposed inside the outer cylinder. A plurality of annular paths communicating with each other are formed in laminar shapes between the inner cylinder, the intermediate cylinders, and the outer cylinder to form a reforming catalyst layer (5 or 13), CO converter catalyst layer (11) and/or CO selective oxidizing catalyst layer (12), and a cooling fluid path (48) for feeding a reformation material gas and reforming water, and air path (42). According to this reformer, buckling of each constituent member is prevented to prevent a decrease in operation performance, and a heat radiation loss is reduced, thus realizing a compact reformer with high start-up speed and high operation efficiency. Furthermore, since this reformer can produce a hydrogen-rich reformed gas having low CO concentration, the reformer is best suited for use in combination with a polymer electrolyte fuel cell.
