Abstract: A antiglare layer (12) having a fine uneven surface is formed directly or through other layers) on a transparent substrate film (11), and a layer (13) having a low refractive index, which is lower than the refractive index of the antiglare layer (12), is formed thereon. The refractive index of the antiglare layer (12) is higher than the refractive index of a layer in contact with said antiglare layer (12) on its surface remote from the layer (13) having a low refractive index. An SiO X film may be used as the layer (13) having a low refractive index. The SiO X film per se has excellent gas barrier property and antifouling property as an optical functional membrane and is an optical functional material characterized by having excellent moistureproofness, scratch resistance, adhesion to a substrate, transparency, low refractive index, dye deterioration preventive property, and other properties.      A layer (13) having a low refractive index as a surface layer is formed through other layer(s) on a transparent substrate film (11), and at least one of the other layer(s) is a hard coat layer (12) of 0.5 µm or more in thickness, having a high refractive index, composed mainly of a resin. The hard coat layer (12) having a high refractive index is in direct contact with a layer (13) having a low refractive index. The refractive index of the hard coat layer (12) having a high refractive index is higher than the refractive index of a layer in contact with the hard coat layer (12) having a high refractive index on its surface remote from the layer (13) having a low refractive index. For use, the antireflection film is laminated to a polarizing plate or a liquid crystal display device.

Title: Global control of hvac distribution system
Inventor: AHMED OSMAN
IPC: F24F11/04
Filed: 1995-10-03
Granted: 1999-05-25
Abstract: A global control system is implemented in a heating, ventilation and air-conditioning (HVAC) distribution system. The system allows local controllers and a source controller to exchange data between one another so that optimization of control for a local component is not sacrificed for optimization of control for a source component, and vice versa. The controllers have their control process sudivided into an identification process and a control process. The identification process periodically identifies characteristics related to the component to be controlled. The control process continuously generates a control signal to be applied to the component to control the component. The control process is further subdivided into a feedforward process and a feedback process. The feedforward process utilizes the identified characteristics to generate a control signal based on calculated system variables, while the feedback generates a control signal based on measured system variables. The two control signals are then combined to control the component. The combination of the control signals produces a more accurate control signal since the effects of noise related to the measured system variables are mitigated by the combination of control signals.
Patent CA-2162091-C (CA)

Abstract: A distortion compensating circuit comprises a frequency control section, a filtering section and an eliminating section.  Major frequencies are detected from an input signal including major signals having the major frequencies by a major frequency detector performing spectrum analysis of the input signal.  Receiving the major frequencies, the frequency control section calculates distortion frequencies from the major frequencies based on predetermined formulae representing the nonlinear distortion.  The predetermined formulae are stored in advance.          The frequency control section generates frequency control signals indicating the distortion frequencies.  After the input signal is divided into a first signal and a second signal, the filtering section extracts frequency components having the distortion frequencies from the first signal in response to the frequency control signals.  The frequency components are eliminated from the second signal by combining the phase-reversed frequency component with the second signal by the eliminating section.

Title: Cuffed oro-pharyngeal airway
Inventor: GREENBERG ROBERT S
IPC: A61F2/958
Filed: 1994-08-16
Granted: 2001-10-02
Abstract: A new type of airway, the cuffed oro-pharyngeal airway (COPA) (10), is described, which may be used as a less cumbersome alternative to face mask/oral airway technique for maintenance of general anesthesia.  The airway includes an elongated tube (12) having a length such that the proximal end (20) is adapted to be disposed adjacent to, but outside, the oral cavity of the patient, and the distal end (36) is adapted to be disposed in the lower pharynx of the patient, above the epiglottis (26). An inelastic, inflatable cuff (14) is mounted to the tube adjacent the distal end (36). On inflation, the inflatable cuff displaces the soft palate against the nasal pharynx to seal off the nasal passages and defines a seal between the tube and the pharyngeal wall. The inflatable cuff (14) also displaces the base of the patient's tongue (30), thereby locking the tube in the pharynx and displacing the patient's epiglottis (26) to a more open disposition for more effective anesthesia gas delivery to the lungs.

Abstract: The present invention relates to a method and apparatus for pouring molten material, such as molten metal, into a casting mold so that the amount of melt can be weighed in connection with the pouring. In order to keep the pouring height of the molten material low and its motion as smooth as possible during the pouring step, the bottom of the ladle containing molten material is designed to be essentially curved, with such a radius of curvature that the thickness of the molten layer located in the ladle is, even at its thickest, only a fraction of the length of the radius of curvature of the bottom. The casting method of the invention is advantageously realized by means of a cradle arrangement of the ladle according to the invention.

Abstract: A self propelled windrower is provided with a platform including a reel which sweeps crop to be cut over a sickle cutterbar and into the nip of a pair of counter-rotating center-feed augers that, in turn, deliver the crop to the nip of a pair of counter-rotating conditioner rolls; and these driven components may be reversed to disgorge slugs of crop. The reversible drive includes a hydraulic pump carried by the traction unit and coupled to a motor carried by the platform. The hydraulic motor on the platform is coupled to power a main gear box which distributes power to the driven components of the platform.
