Patent CA-2364219-C (CA)
Inventor: ST LOUIS ROBERT MAURICE
IPC: D06F34/10

Granted: 2007-01-09
Abstract: A control circuit for a clothes dryer operating with a 120 volt power supply compensates for changes in the ambient temperature to compensate for premature advancement of the dryer timer motor during an automatic drying cycle. The control circuit has a thermally biased low outlet thermostat and a thermally biased high outlet thermostat which control the energization of a heater in the dryer. The low outlet thermostat and the high outlet thermostat each open circuit at respective lower and higher predetermined temperatures when the outlet air flow from the dryer drum reaches the lower or higher respective predetermined temperatures to thereby de-energize the heater and advance the timer motor. The control circuit includes a thermally biased ambient thermostat that is normally open and unbiased, and that switches control of the heater energization from the low output thermostat to the high outlet thermostat when thermally biased and when the ambient temperature rises above a predetermined ambient temperature. The ambient thermostat becomes thermally biased when the low output thermostat is open circuited. Both the low and high output thermostats are normally thermally biased during the automatic drying cycle and are un-biased during user time selected drying cycles so that the low and high temperature thermostats cycle on and off at higher temperatures than they would during the automatic drying cycle.

Title: Bolted joint for rotor disks and method of reducing thermal gradients therein
Inventor: EBERT TODD ALAN
IPC: F02C7/00
Filed: 2001-12-13
Granted: 2007-09-11
Abstract: Rotor disk stress is reduced in a bolted joint (52) for connecting adjacent rotor disks in a gas turbine engine (10). The bolted joint (52) includes a bolt hole (70) formed in the first rotor disk (40) and a tube (82) disposed in the bolt hole (70) such that a channel (84) is defined between the tube (82) and the bolt hole (70). A bolt (66) is disposed in the tube (82) such that a gap (88) is defined between the bolt (66) and the tube (82). The gap (88) thermally insulates the bolt (66) from hot fluid in the channel (84). A first passage (96) provides fluid communication between the channel (84) and a forward cavity, and a second passage (98) provides fluid communication between the channel (84) and an aft cavity. Hot fluid passing through the channel (84) reduces thermal gradients in the first rotor disk (40). The tube (82) thermally shields the bolt (66) from the hot fluid to minimize differential thermal growth.

Title: Control of a variable geometry turbocharger by sensing exhaust pressure
Inventor: MURPHY BRIAN J
IPC: F02D41/00
Filed: 2001-01-20
Granted: 2006-11-28
Abstract: There is provided a system and method for using an engine's exhaust back pressure (1210) to control a variable geometry turbocharger. The control system determines a desired exhaust back pressure (1205) based on engine parameters. The desired exhaust back pressure (1205) is then compared with a measured exhaust back pressure (1210) to determine the difference (1215) between the measured (1210) and desired (1205) exhaust back pressures.  The difference value (1215) is used to determine the duty cycle (1220). In an alternate embodiment, the exhaust gas pressure (1615) is used to adjust the duty cycle (1605) determined based on the engine parameters. The difference (1620) between the measured (1615) and desired (1610) exhaust back pressures is used to determine an exhaust pressure control duty cycle (1625). The base duty cycle (1605) is then adjusted by the exhaust pressure control duty cycle (1625) to give a turbocharger duty cycle (1630).

Abstract: Techniques to control the transmit power of multiple transmissions in wireless communication system. A transmitting source (e.g., a base station) receives from a receiving device (e.g., a remote terminal) a number of feedbacks of one or more (coded or uncoded) bit streams and possibly one or more messages. The bit stream may include one or more power control sub-channels used to send one or more metrics (e.g., power control commands, erasure indicator bits, or quality indicator bits) for one or more sets of channels. The bits allocated for each sub-channel may be aggregated to form one or more lower rate feedback sub-streams having improved reliability. The transmit power of two or more channels can be (1) independently adjusted based on the feedbacks from respective sub-channels, or (2) adjusted together based on feedback from one sub-channel, with the power difference being adjacent based on feedback from another sub-channel.

Abstract: An ultraviolet area sterilizer (UVAS) is mobile or stationary. The UVAS is positioned in a room, such an operating room or intensive care unit. Motion detectors sense movement, to assure that personnel have evacuated the space to be sterilized. Subsequently, UV-C generators, such mercury bulbs, generate UV-C from multiple locations within the room or other enclosed space. Multiple UV-C sensors scan the room, and determine the area reflecting the lowest level of UV-C back to the sensors. The device calculates the time required to obtain a bactericidal dose of UV-C reflected back to the sensors. Once an effective bactericidal dose has been reflected to all the sensors, the unit notifies the operator and shuts down.

Patent CA-2406754-C (CA)
Inventor: BRENNAN ROBERT
IPC: G10L21/0232
Filed: 1998-04-16
Granted: 2009-06-30
Abstract: A hearing aid includes noise reduction, and addresses the problem that, in noisy conditions, it is difficult for hearing impaired individuals to hear. Under light noise conditions, conventional hearing aids amplify the input signal sufficiency to overcome the hearing loss. For a typical sloping hearing loss where there is a loss in high frequency hearing sensitivity, the amount of boost (or gain) rises with frequency. Most frequently, the loss in sensitivity is only for low-level signals; high level signals are affective minimally or not al all. A compression hearing aid is able to compensate by automatically lowering the gain as the input signal level rises. This compression action is usually comprised under noisy conditions. In general, hearing aids are of lesser benefit under noisy conditions since both noise and speech are boosted together when what is really required is a reduction of the noise relative to the speech. A noise reduction algorithm with the dual purpose of enhancing speech relative to noise and also providing a relatively clean signal for the compression circuitry is described.

Granted: 2005-08-16
Abstract: A method and apparatus for translating linear movement into rotational movement in an actuator configuration is provided. For example, a rotary actuator assembly includes a housing having a central bore. A piston is disposed within the housing and is linearly movable along an axis of the central bore. A rolling diaphragm is disposed within the housing and coupled with the piston. A bifurcated linkage having an end flange couples with the piston and the rolling diaphragm. An articulatable coupling further connects the bifurcated linkage with a rotating linkage. A  spring button, which can be cone shaped, is disposed within the housing. A  compression spring is retained between the end flange of the bifurcated linkage and the spring button, for example, by a threaded rod and nut. The assembly is arranged such that when force is applied to the rolling diaphragm the bifurcated linkage is linearly transported; which results in the pivoting of the rotating linkage about a pivot point. The pivot point can couple to a valve stem to control a valve.

Title: Ammonia recovery from purge gas
Inventor: SPETH CHRISTIAN
IPC: B01D53/04
Filed: 2003-03-14
Granted: 2010-05-25
Abstract: The invention relates to ammonia synthesis loops containing gasses, which do not react and would accumulate if they were not purged out. By the present invention ammonia in a purge gas is recovered by an adsorption agent operating at the full synthesis loop pressure. The adsorption agent is chosen in such a way that the ammonia can be removed again by passing a gas comprising hydrogen and nitrogen through it at the same elevated pressure as the loop pressure. This enables the adsorption agent to be regenerated by fresh synthesis gas coming from the synthesis gas compressor just before this gas enters the synthesis loop. Thereby, the re- generation requires an absolute minimum of energy consump- tion and equipment.
