Title: Enhanced subscriber line interface circuit
Inventor: WARNER MICHAEL
IPC: H04M7/00
Filed: 1991-05-15
Granted: 1998-10-06
Abstract: An enhanced subscriber line interface circuit for a digital switching system over which a connection is established between a digital switching system and a subscriber instrument via a subscriber line.  The enhanced subscriber line interface circuit includes a line configuration and protection circuit connected to the subscriber line and to a thick-film hybrid module.  The thick-film hybrid module comprises in combination a high voltage interface circuit and a PCM conversion circuit. The high voltage interface circuit provides power to the subscriber line, converts received analog voice signals transmitted from the subscriber instrument into differential voltage voice signals and detects the subscriber lines status.  The PCM conversion circuit is connected to the high voltage interface circuit and is disposed to convert received differential voice signals into PCM digital signals.  A line control interface circuit is also provided located remote from the thick-film module. The line control interface circuit receives control signals from a peripheral processor of the digital switching system and controls the operation of the circuits of the thick-film hybrid module.  Additionally, the line control interface circuit receives subscriber line information from the high voltage interface circuit which it passes on to the peripheral processor.  A time slot assignment circuit connected to the peripheral processor is arranged to develop and transmit to the PCM conversion circuit time slot assignment information and to connect the PCM digital signals from the enhanced subscriber line interface circuit to the digital switching system.

Title: Dual element fuse
Inventor: MORGAN PETER
IPC: H01H85/36
Filed: 1992-10-02
Granted: 1998-05-19
Abstract: An electrical interruption device is disclosed in which a space efficient spiral spring activates current interruption.  The spring is characterized by coils which wind continuously about and approach a central axis, with successive coils of the spring having reduced radius to pass axially through the center of an outwardly adjacent coil.          The spring may further be made to assume a flat condition with the spring coils lying flat, nesting interposed between adjacent coils.  Advantageously, the spiral spring is conical in shape and is tensioned in a reverse loaded configuration wherein the coils of one end of the spring are pulled axially inward, through and past the coils of other end.  Preferably the reverse loaded conical spring forms part of a thermally sensitive device which includes a housing having disposed therein a plunger which is in a biased relationship with the spring.  The plunger extends beyond the housing to provide electrical communication with the remainder of the electric circuit, and is held in place against the force of the spring by a meltable solder.  On a predetermined condition causing the solder to melt, the plunger is released, whereby it is moved by the force of the spring into the housing and out of electric communication with the remainder of the electric circuit.

Patent CA-2084214-C (CA)
Inventor: ZECHNER KURT
IPC: A61M15/00
Filed: 1992-12-01
Granted: 2003-09-09
Abstract: An inhaler for delivering metered doses of a particulate drug. The inhaler is formed of a housing, a drug reservoir attached to the housing to contain multiple doses of the particulate drug, a drug transporting slide in the housing that contains a metering chamber of volume corresponding to a desired dose of the drug, and a vacuum pump that creates a partial vacuum in the metering chamber. The drug transporting slide is movable from a load position, in which it communicates with the drug reservoir to receive in its metering chamber drug from the drug reservoir, to a release position in which it communicates with an air outlet passage to release drug from the metering chamber into the air outlet passage.      The drug reservoir has an air permeable portion that permits air flow into the drug reservoir but prevents drug escape. In use, the vacuum pump draws a dose of drug into the metering chamber. The drug transporting slide then moves to deposit the drug in the outlet passage for inhalation.

Title: Quick disconnect fluid coupling with integral pressure relief feature
Inventor: ROGERS RUSSELL L
IPC: F16L37/34
Filed: 1992-12-07
Granted: 1996-03-26
Abstract: A quick disconnect fluid coupling for a liquid-cooled, preprogrammed card for an aircraft communication or navigation system, the coupling being made up of male and female coupling elements which are closed to flow in the free or uncoupled state and which are open to flow when coupled.    The male  coupling element  has  an  integral pressure relief feature which operates in two phases.  In a first phase the male coupling element remains closed to fluid flow, but accommodates an increase in fluid pressure by movement of an annular valve sleeve within in outer annular member to increase the fluid volume within the annular member.  In a second phase an end of a valve member of the male coupling element is biased away from sealing engagement with an end of the annular valve sleeve by fluid pressure, against the biasing effect of a return spring which is trapped between the annular valve sleeve and a perforate annular retainer that is affixed to an opposed end of the valve member, to permit fluid to be dumped from the coupling element.

Title: Cysteamine permanent wave composition and method
Inventor: NANDAGIRI ARUN

Filed: 1993-01-06
Granted: 1996-08-27
Abstract: A single formula, mild permanent wave reducing composition and method of permanently waving or reshaping human hair that provides a strong, long lasting curl and leaves the hair soft while minimizing further damage to already damaged hair. The composition contains a cysteamine reducing agent compound selected from the group consisting of cysteamine, a cysteamine salt, and mixtures thereof; preferably alone (without a monothioglycolate; a monothioglycolic acid ester, e.g., thioglycerol; a thiolactic acid; a sulfite; a hyposulfite, or a bisulfite second reducing agent). The cysteamine compound should be present in an amount of about 7.8% to about 9.0% by weight; and sufficient additional alkali, if necessary, to bring the pH of the composition to about 7.8 to about 8.5. Optionally, a hair softening and/or moisturizing agent, such as glycerine is included in the composition in an amount of about 0.1% to about 15% by weight of the composition. The composition can be lotion or water wrapped and can be used with or without heat. Unexpectedly, the composition is applied to any type of hair, regardless of structural damage to the hair, resulting in the same degree of curl tightness and softness and can be applied much more frequently than prior art permanent wave compositions without significant damage to the hair.
