Title: Biodegradable Mesh and Film Stent
Inventor: TURNLUND TODD HANSON
IPC: A61F2/82
Filed: 1995-06-26
Abstract: A biodegradable mesh-and-film stent for use in blood vessels is formed of a sheet of a composite mesh material formed of biodegradable high-strength polymer fibers  bonded  together  with  a  second  biodegradable adhesive polymer, and laminated on at least one side with a thin film of  a third biodegradable polymer.   The biodegradable mesh-and film material is formed as a sheet and cut in a shape that can be used as a stent, such as a "belt-buckle" type shape,  the ends of which can be joined in a contractible, expandable loop.  In the method of  making  the  biodegradable  composite  mesh-and-film stent, the composite mesh preferably is formed from a weave formed of high-strength biodegradable polymeric fibers,  and  a  plurality  of  low-temperature  melting biodegradable  polymeric  fibers.     In  an  alternate embodiment, the high strength fibers are co-mingled with the low-temperature melting fibers.  In another alternate embodiment, the high-strength fibers are coated with the low-temperature melting polymer.  The composite mesh is covered on at least one side by a laminating film, and then is cut into the shape of the stent.

Abstract: A spin-on filter includes a baseplate secured to an end cover and further includes a filter element disposed in a canister having an open end.  The end cover is secured to the open end of the canister by seaming a flange formed at the edge of the end cover with a flange formed at the end of the canister.  An end cap which is secured to the filter element is trapped between the baseplate and the seamed flanges, thereby securing the filter element in the canister and avoiding the need of a helical spring for urging the filter element toward the baseplate.

The present invention also provides a method for maintaining an alarm circuit within its sensitivity range, the alarm circuit including an emitter and a detector and having a background signal and a preset alarm threshold signal. The method involves a) increasing the background signal by a gain factor to produce a first test signal; b) comparing the first test signal against an alarm threshold signal; c) reducing the background signal by a reduction factor to produce a reduced background signal; d) increasing the reduced background signal by a gain factor to produce a second test signal; e) comparing the second test signal against the alarm threshold signal; and f) adjusting the emitter output and/or the alarm threshold signal if necessary to maintain the first test signal greater than or equal to the alarm threshold signal and the second test signal less than or equal to the alarm threshold signal.
Patent CA-2176308-A1 (CA)
Title: Pdh/sdh signal processor with dual mode clock generator
Inventor: DOI TAKASHI
IPC: H03B28/00
Filed: 1996-05-10
Abstract: A signal processor comprises a first circuit for extracting a PDH (plesiochronous digital hierarchy) signal from an incoming SDH (synchronous digital hierarchy) signal and a second circuit for adding an overhead to an incoming pure SDH signal to produce a synchronous transport module (STM) output signal. The output of the first circuit is selected when the incoming signal contains the PDH signal and the output of the second circuit is selected when the pure SDH signal is received. A local oscillator produces a first clock signal when the incoming signal contains the PDH signal or a second clock signal when the pure SDH signal is received. A read/write circuit is provided for storing the selected signal into a buffer at a first rate and reading the stored signal from the buffer at a second rate. The difference between the first and second rates is detected by a comparator. A microprocessor-controlled oscillator, which operates in a frequency synthesizer mode when the PDH signal is contained in the incoming signal or in a phase locked mode when the incoming signal is a pure SDH signal, is responsive to the difference value for generating a clock signal whose intervals are averaged during the frequency synthesizer mode and whose intervals are locked to the difference value during the phase locked mode. The output of the microprocessor-controlled oscillator is mixed with either of the first and second clock signals from the local oscillator to produce a line clock signal at which the second rate of the read/write circuit is set.

Patent CA-2177131-A1 (CA)
Inventor: LANGE JACK
IPC: F26B21/00
Filed: 1996-05-30
Abstract: A heater for a grain bin is attached to the inlet flange of a centrifugal inline blower and comprises a housing having a vertical front wall attached to the inlet flange of the blower and a parallel vertical rear wall. The front wall has an opening aligned with the opening into the blower. The rear wall has an opening aligned with the opening in the front wall so that the majority of the air entering the blower passes straight through the housing from the rear wall to the front wall. A sleeve surrounds the opening in the rearwall and induces some flow from the housing to mix with the flow into the blower. The combustion chamber is attached to the rear wall through an opening in the rear wall above the sleeve. The housing has two side walls converging to an open top through which air can escape. When heated air is required an air flow is induced from the combustion chamber to mix with the air flow through the housing to heat the total air flow. In the event that air flow fails, the heat escapes through the open top thus avoiding the necessity for complex interlocks.
