Title: Flushing system for a water closet
Inventor: BARRETT JOHN P SR
IPC: E03D5/10
Filed: 1992-12-23
Abstract: IMPROVED FLUSHING SYSTEM FOR A WATER CLOSET            ABSTRACT OF  THE DISCLOSURE:      An apparatus and method is disclosed for an improved flushing system for flushing a water closet from a pressurized water line. A sensor senses an arrival and a departure of a person within a zone proximate the water closet. A controller is connected to the sensor for determining the existence of a low water volume flush condition and the existence of a high water volume flush condition. The low water volume flush condition exists when the sensor senses an elapsed time between the arrival and the departure of less than a preselected time interval.          The high water volume flush condition exists when the sensor senses an elapsed time greater than the preselected time interval.

Abstract: A structure and its method for manufacture for a switchable optical filter.  The structure comprises a substrate (10) transparent to the radiation of interest, which contains or supports an electrode (12). A spacer layer (16) suspends the membrane over the electrode (12) such that no spacer lies between the electrode (12) and the membrane (22), yet some spacer (16) remains elsewhere to support the membrane (22). The membrane has slots (24) in it which are of a specified length in order to resonate at a particular wavelength of radiation. When the electrode (12) is activated, the membrane (22) deflects and its varying proximity to the substrate changes the wavelength of transmission.

Patent CA-2098156-A1 (CA)
Inventor: SEIFERT GUENTER
IPC: B08B9/08
Filed: 1993-06-10
Abstract: ABSTRACT         Apparatus for mechanically removing circumferentially complete labels from cylindrical external surfaces of successive containers, such as bottles, which are transported in upright or horizontal position past a removing station has a mechanical or pneumatic device which withdraws a portion of the label from the external surface of a container at the removing station.  This establishes a clearance for a distancing element at the leading end of a knife which is moved axially of the external surface at the removing station to sever the label from one marginal portion all the way to the other marginal portion of the label.  The thus split labels are attracted by an evacuating conveyor as soon as the respective containers advance beyond the removing station.
Patent CA-2098193-A1 (CA)
Title: Bullet trap
Inventor: COBURN RONALD
IPC: F41J13/02
Filed: 1991-10-31
Abstract: A bullet trap for a horizontally fired projectile (B) includes a passageway (13) bounded by upper and lower flat plates (13a, 13b), which may be inclined to the horizontal at an angle (.alpha., .beta.) of between 0· and 15· and define an entrance opening (13c) and a shallow exit opening or throat (13d), and a horizontal generally spiral-walled spent projectile energy-dissipating chamber (15) which communicates substantially tangentially with the passageway through the throat. The circumferential chamber boundary wall (25) has an initial part (25a) which is an upwardly curving extension of the lower plate (13b) and a terminal part (25c) which is located at the rear end of the upper plate (13a). The low angles of inclination of the passageway boundary plates (13a, 13b) ensure that the projectile is gently deflected from its original path of flight and enters the chamber without being shattered by or damaging the circumferential boundary wall of the chamber. A liquid lubricant (27) may be sprayed against the initial part of the chamber wall to engulf and flush lead dust, if any is generated, and other solids into the passageway and thence into a collecting vessel (17), and may be recirculated to the spray head (26) in the chamber.

Title: Recovering audio signals from a variable-area optical record
Inventor: MURPHY JAMES B
IPC: G11B7/003
Filed: 1992-09-04
Abstract: The invention relates generally to the recovery of an audio information signal from a variable-area optical record and more particularly to the recovery of such a signal from motion picture film variable-area optical soundtracks. The invention, in its various aspects, operates in an environment in which a scan signal is obtained by repetitively scanning the optical record substantially transverse to the bias line. The invention enhances the noise reduction effect obtainable using a threshold detector by providing the threshold detector with a transversely varying threshold level that varies according to the position of the scan across the width of the soundtrack. According to the invention, a threshold is provided for a bilateral soundtrack that has a minimum level at the bias line of the soundtrack and that increases progressively with distance from the bias line. Thus, on each scan, the threshold level is high when the scan is at the edge of each sound-track , falls progressively to a minimum when the scan reaches the bias line, and then increases progressively back to its original high level when the scan is at the other edge of the sound-track.

Patent CA-2121677-A1 (CA)
Title: Ergonomic-interface keyboard system
Inventor: SPENCER JEFFREY B
IPC: G06F3/02
Filed: 1992-08-05
Abstract: Conceived with the human-engineering objective of overcoming Repetitive Motion Injuries such as Carpal Tun-nel Syndrome. The solution, a system comprising a split-keyboard spaced laterally into vertically arranged co-opera-tive keypad halves (24, 24') optimally enabling the user to sit with the lightweight portable keyboard (23, 23') assembly laying directly upon their lap. Traditional keyboards orient operator's hands inducing a wrist-twisting, arm-extending stress while the stress-free ergonomic bodily position herein liberates one from such trauma by reorientation of the hands and arms to a non-pronated, unextended position.      This correction involves the upper-arm draping naturally down from the shoulder with the forearm set at a relaxed forward projecting right-angle, placing the Carpalligaments. of one's wrists in a non-torqued, neutral position. Because weight of the extended hand/forearm is borne comfortably upon the narrow side (hypothenar-eminence) of the hand, this newly identified reorientation requires no appreciable musculature effort to maintain. The arrangement of keypad controls, with transverse adjustability to user's physique, serves to ameliorate onset occurrence of keyboard associat-ed RMI-diseases. Utilizing visual-reference mirrors (22, 22') adjustable to a user's eye, enables them to readily reference any key-indicia or tracking-mouse hemisphere (34, 34') via conveni-ence of natural mirror-image/reverse-compensated character notation. The system universally interfaces with ordinary electronic keyboard connections, and employs a conventional (albeit split) Qwerty keyboard. It is likewise adaptable to other keyboard for-mats. Optical accommodation of an Accounting-panel (ten-key; with affixed visual-reference mirror (39) at the right or left of the keyboard-base, is achieved via a modularly invertible attachment upon either laterally extensible retractable-support member.
Patent CA-2123473-A1 (CA)
Inventor: PETTIT FREDERICK B
IPC: G05D23/24
Filed: 1994-05-12
Abstract: ABSTRACT OF THE DISCLOSURE            A transformerless electrical appliance with an AC heating element uses a triac in series with the heating element and a control circuit responsive to a thermistor to regulate flow of heating current. A power supply is formed by a resistive divider that steps down the AC line voltage and a fullwave diode bridge that rectifies the stepped-down voltage. The resistance of the divider is comparatively high, limiting power dissipation in the divider, but incidentally producing significant variations in the power supply voltage (roughly 100% from minimum to maximum levels). The impedance of the divider element which conducts the operating current of the control circuit is selected to ensure that the average minimum power supply voltage is above the minimum operating voltage required by the control circuit. Resistive dividers are used to produce temperature and reference signals from the power supply voltage, making switching of the triac relatively immune to the significant variations in the supply voltage.
