Patent CA-2123446-A1 (CA)
Title: Container cover and dispensing device
Inventor: LINDMAYER STEPHAN
IPC: B65D83/14
Filed: 1994-05-12
Abstract: Carbonated colas and other pressurized liquids are often sold in large bottles with screw-on caps. Dispensing of the contents of the bottles can be messy, and once the bottles are opened the carbonation quickly dissipates. A simple cover and dispenser combination for bottles includes a cap for mounting in sealing engagement on the top end of a bottle; a sleeve extending downwardly from the center of the cap for receiving liquid from the interior of the container, and for discharging the liquid through a central opening in the cap; a valve seat in the sleeve around the bottom of the opening; and a valve in the sleeve, the valve including a tubular body fixed in the sleeve, a head on the body normally sealing against the valve seat, a plunger extending upwardly from the head through the central opening, and a resilient cage, defining a section of the body beneath the head, whereby the plunger can be pressed downwardly to deform the cage and open the valve by moving the head away from the seat, permitting the dispensing of fluid through the opening.

Inventor: ONISHI ICHIRO
IPC: B60N2/28

Abstract: The child safety seat for an automobile comprises a seat body forming a backrest which is arcuately movable with respect to a base.  A relative movement guiding mechanism, which is formed by combining an arcuately extending guide rail and a guide member moving along the guide rail, allows for movement of the seat body with respect to the base.  A seat is rotatably mounted on the seat body and a coupling member engages a linear portion of the guide rail, thereby maintaining the seat in a substantially constant inclination regardless of movement of the seat body.  Thus, the seat can remain in a substantially horizontal state when the angle of the backrest is adjusted, while the backrest may recline without interfering with the backrest of an original seat in the automobile upon which the child safety seat is mounted.  Thus, the child is not forced into an uncomfortable position when the backrest of the child safety seat is reclined.

Title: Lap carrier
Inventor: HAHM MANFRED
IPC: D06B23/04
Filed: 1993-01-16
Abstract: The invention concerns a yarn bobbin with a rotationally symmetrical body the outside of which forms a surface which carries the yarn and which has a longitudinally protuding collar at one end. The aim of the invention is to design a bobbin of this kind which has the advantages of prior art bobbins but which, when wound, can be stacked with other, similar, bobbins without the yarn being damaged or snagged. The invention achieves this by virtue of the fact that the bobbin (1) has, at its end with the yarn uptake (2), an additional collar (3) which has the same external dimensions as the internal dimensions of the collar (4) at the other end of the bobbin but is staggered radially inwards with respect to the yarn uptake, the collar (4) being fitted with a yarn-reserve groove (6).

Title: Cryogenic cooling system with active vibration control
Inventor: WU YEONG-WEI A
IPC: G05D19/02
Filed: 1994-11-07
Abstract: A cryogenic cooling system having a mechanism for canceling vibration at a fundamental frequency and at harmonics thereof.  The inventive system includes a first apparatus (28, 32)  for cooling a mass.  The first apparatus (28, 32) creates a vibration at a first frequency and a second frequency.   In a typical application, the first frequency is a fundamental frequency and the second frequency is a harmonic of the first frequency.  Often several harmonics are present. The invention includes a second apparatus (30, 34) for substantially eliminating vibration at the first frequency  and  a  third  apparatus  (48,  50)  for substantially eliminating vibration at the second frequency.  The second apparatus includes a mass (30) and a motor (34) for driving same.  The mass (30) is disposed to counter the vibration created by the first apparatus when the motor (34) is driven by a first current.  The third apparatus includes a sensor (48) for detecting the vibration at the second frequency and providing an output in response to a sensed force F resulting therefrom. The third apparatus further includes a feedback circuit (50) for providing a second current for driving the motor. The second current is the sum of the first current and a feedback current Ib2.  The  feedback current Ib2 is equal to -Gf(s)F, where -Gf(s) is a feedback transfer function. The feedback transfer function is a product of a first transfer function HI(s) representing dynamics of the second apparatus required to cancel the vibration at the first frequency and a second transfer function GD(s) representing the dynamics of the second means required to cancel the harmonic vibration.

Title: Method of increasing the catalytic activity of a glycanase having two or more catalytic domains
Inventor: FORSBERG CECIL W
IPC: C12N9/24
Filed: 1994-11-28
Abstract: A method for increasing the catalytic activity of a glycanase having two or more independent catalytic domains by isolating the catalytic domains from the intact enzyme is described. If the catalytic domains in the intact enzyme are linked by a proline/hydroxyamino acid-rich linker sequence, the catalytic domains can be isolated and activated by cleavage within or adjacent to the linker sequence with a protease. The catalytic domains can also be isolated, whether or not they are linked by a hydroxyamino acid-rich linker sequence, by expressing the DNA sequences encoding each domain in separate transformed microbial hosts. An isolated and purified low-activity xylanase, denoted XynC, and which is obtained from Fibrobacter succinogenes is also described. XynC contains two independant active catalytic domains separated by a serine rich linker region. The enzyme has a mass of 63 kDa and an activity of 6 U/mg (µmol/min/mg) protein. The subcloned domains expressed separatedly exhibit 55 to 116 fold higher activity than the intact enzyme has a specific activity of approximately 6 U/mg protein and a mass of 63 kDa and consisting of two independently active catalytic domains linked by a hydroxyamino acid-rich linker sequence. XynC can be activated by treatment of the intact enzyme with a protease. The utilization of feed by domesticated animals and poultry can be improved by admixing the feed with XynC and a catalytic quantity of protease as the XynC is activated by proteases indigenous to the digestive tract of the animal.

IPC: E04F15/18
Filed: 1995-03-16
Abstract: In the building and construction trade it is common to have a finished concrete floor over which one desires to place an insulated sub-floor.         At present this subfloor is constructed by first laying a moisture barrier over the floor, by then framing the concrete floor, by then laying insulation down between the frames, and by then covering the framing with plywood or other wood sheeting.          This method is labour intensive, and the materials required are costly.          In this invention, the subfloor is made of prefabricated modular panels, ideally 8 foot by 4 foot, or 4 foot by 4 foot, or 2 foot by 8 foot in size, made of plywood or other suitable material, and with insulation, applied to the underside. The panel is raised by a perimeter frame and centred supports. The panels can be designed to interlock with one another.          The subfloor is easily installed by laying the panels over the moisture barrier on the concrete floor side by side and end to end and affixing together and to the concrete floor beneath. The subfloor panels can be cut to size to fit the room' s perimeter.

Title: Stiff actuator active vibration isolation system
Inventor: SCHUBERT DALE W
IPC: G03F7/20
Filed: 1995-04-03
Abstract: An active vibration isolation system (10) includes a plurality of stiff actuators, such as piezoelectric motors (12a-c; 284, 350) which support a small mass (18) inside of a case (300). A passive isolator (20) is interposed between the small mass (18) and the payload mass (Mp). In the instance where the stiff actuators are piezoelectric motors, the sidewalls of the case (300) are used to provide compressive force along the variable length of each of the horizontal piezoelectric motor elements (284, 350) to prevent damage to same. Compensation circuitry (24) is connected between velocity sensors (17) and the stiff actuators to control the variable length thereof in this move-out-of-the-way system (10) and to compensate for resonating modes. Optionally, a payload mass velocity sensor (26) and associated circuitry may be used to provide additional control. Shear decouplers (282a-c; 352, 360) are used in conjunction with the piezoelectric motor elements (12a-c; 284, 350) to minimize the amount of shear force acting on the motor elements.
