Patent CA-2108470-C (CA)
Title: Roll-up thermal insulator
Inventor: ASMUSSEN EDGAR
IPC: E06B9/24
Filed: 1992-04-13
Granted: 1997-03-25
Abstract: The invention concerns a roll-up thermal insulator (100; 200) in the form of a planar structure which, when unrolled, forms a multi-chamber sys-tem for providing air-filled, preferably circulation-free subdivisions whose vo-lume decreases again when the insulator is rolled up. The aim is to develop the insulator so as to obtain even better thermal insulation values, increase the transparency and provide additional light-controlling effects, while retaining its compactness when rolled up. To this end, the planar structure is designed as an insulating mat (112) which has at least two films disposed one behind the other (121 to 127) whose distance apart can be controlled by spacer rods (142 to 147) offset by a vertical distance (AV) and articulated to adjacent films.

Abstract: A method of  producing  a  hardwood  flooring product, including the steps of processing a strip of raw wood into a blank having a predetermined thickness and width,  and top and bottom surfaces defining parallel planes relative to each other,  and splitting the blank along the width of the blank from one side to the other to form two low profile flooring strips having the same width as the blank and a thickness less than one-half the thickness of the blank.  The splitting step includes the steps of providing first and second circular saw blades mounted on spaced-apart vertical axes for rotation in a single plane intermediate and parallel to the planes of the top and bottom surfaces of the blank and positioning the blank on conveying means upstream from the saw blades with the plane of rotation of the saw blades intermediate and parallel to the planes of the top and bottom surfaces of the blank for movement of the blank from an upstream position to a downstream position relative to the saw blades.  The blank is moved downstream into the plane of rotation of the saw blades during rotation of the saw blades thereby horizontally splitting the blank to   form  first  and   second   low-profile   flooring   strips.         Interlocking members, such as molded, mating tongue and groove members, are molded into first and second longitudinally-extending side edges of the flooring strips for securing together the flooring strips when placed side-to-side to form a floor.

Abstract: A method for providing narrowband-related service features to subscribing broadband lines comprises establishing a composite voice path interconnecting a narrowband server and the subscribing broadband line via a broadband switching fabric. Particularly, a call set-up signal is received in a broadband call processor, converted to narrowband signaling format and extended to a designated narrowband server. Responsive to receipt of the call set-up signal, the designated narrowband server establishes a narrowband voice path interconnecting a narrowband network element to a synchronous-asynchronous converter. Subsequently, the broadband call processor establishes a broadband segment interconnecting the subscribing broadband line with the synchronous-asynchronous converter. The broadband segment corresponds to the narrowband voice path to form a composite voice path. The composite voice path is used by the designated narrowband server to provide narrowband-related service features to the subscribing broadband line. After a call in which narrowband-related features may be invoked has been disconnected, the composite voice path is released.

Abstract: A pneumatic human power amplifier module is usable in conjunction with a wide variety of pneumatic actuators and lifting devices to provide a human power amplifier for lifting a load.  The module includes an end-effector, an electronic controller and a pneumatic circuit.  The end-effector contains a human interface subsection which is grasped by a human operator and a load interface subsection which engages the load to be lifted.  A force sensor in the end-effector detects the force imposed by the operator on the end-effector and transmits a signal representing the magnitude of the force to the controller.  The controller in turn sends a command to the pneumatic circuit, which controls the flow of air into the associated pneumatic actuator. The actuator drives the lifting device.  The controller and the pneumatic circuit are arranged such that the lifting device and the operator share the burden of lifting the load, with the operator supplying a predetermined percentage of the total force required to lift the load regardless of the size of the load.

Abstract: A laser to produce pulses of light having predetermined spectral shapes, comprising a waveguide, an optical pump source, a gain medium to produce seed radiation, and a modulator and an array of Bragg gratings to modify the properties of the seed radiation. Once generated by the gain medium, the seed radiation propagates in the waveguide where it is first pulsed by the modulator. The resulting pulses are then selectively reflected by the Bragg gratings, which separates different spectral components of the reflected beam.      This reflected beam then travels back to the modulator, which is timed to let only the desired spectral components go through. In this manner the laser is self-seeded and allows spectrum and wavelength selection from pulse to pulse.
