Title: Information transmission system and method of operation
Inventor: CAMPANA THOMAS J JR
IPC: H04W84/02
Filed: 1993-08-26
Abstract: A system for atmospheric transmission (102, 600) of information subject to fading for a time interval using a radio frequency carrier (106, 616)  modulated with a subcarrier (Figs. 7A and B) provides a first encoded information stream (Fig. 8) and a second encoded information stream (Fig. 8) being delayed by a time delay interval (Fig. 7) with respect to the first information stream which is equal to or greater than the time intend of the atmospheric fading and an encoder. The first and second encoded information streams modulate the subcarrier to produce identical first and second parallel information streams modulated on cycles of the subcarrier.  Receiving circuit (Fig. 23) receives the parallel information streams and has a detector for detecting transmitted streams and at least one processor, responsive to the detected parallel information streams, for determining if faded information is present in at least one of the detected streams and in response to determined faded information replacing faded information with information which is time offset.

Title: Device for preventing the risk of fire due to burning or glowing particles in a pipeline
Inventor: JANSSON LENNART CARL ERIK
IPC: A62C3/04
Filed: 1994-10-03
Abstract: The present invention relates to a preventive safety system which may be used in a process in which loosely-formed process material is produced in a first unit (1) and is transportable to a receiving, second unit (2), and in which process the treatment of material in the first unit is liable to generate a hazardous particle or particles which has/have a temperature which is sufficiently high to inidate burning and/or an explosion in at least the second unit. The requisite trans-portation of the loosely-formed material between the first unit and the second unit is effected through the medium of a stabi-lizing zone (7), an indicating zone (9) op-erative in indicating the presence of haz-ardous high-temperature particles, and an extinguishing zone (9), wherein the indi-cating zone (8) includes one or more haz-ardous particle sensors, wherdn the sen-sors coact with an indicating and activat-ing unit (12) such that when the presence of hazardous high-temperatures particles is detected by a sensor (10) in the in-dicating and activating unit (12) there is activated a device (15) which is located in the extinguishing zone and which functions to deliver an extinguishing agent and/or to remove said hazardous particles from the system. A detection-dependent intensity can be evaluated in the activating unit (12) and that measure or procedure which is most suitable at that time selected in the indicating and activating unit (12) from a number of available safety measures and safety procedures (19, 20, 21).

Patent CA-2183324-A1 (CA)
Inventor: SHONFELD DAVID
IPC: A61M5/00
Filed: 1995-02-13
Abstract: L'invention décrit une seringue (1) à usage unique. Le plongeur (14) est en forme de tige et fait d'une pluralité de dents cylindriques (28) en cliquet. Un clip élastique de verrouillage (6) fait d'un matériau élastique est suspendu sur ladite partie à cliquets du plongeur, et l'emplacement du clip élastique de verrouillage détermine la dose maximale qui peut être administrée avec la seringue. Pendant l'utilisation, un premier retrait du plongeur par rapport au corps (8) permet d'aspirer du médicament dans la cavité du corps puisque la dent de came (21) du clip élastique de verrouillage glisse par flexion radiale sur la surface des dents de cliquet et le clip élastique de verrouillage est cependant maintenu dans une position relative le long du corps par des points de contact (18) orientés vers l'extérieur qui sont logés dans la paroi latérale intérieure (17) du corps. Pendant l'administration de médicament, le clip élastique de verrouillage se déplace avec le plongeur car la dent de came orientée vers l'intérieur coopère avec la base d'une dent de cliquet et est portée le long de celle-ci. Le mouvement alternatif ne peut pas être répété une fois que le clip élastique de blocage a été déplacé vers sa position distale extrême, dans laquelle il est amené par la poussée de la dent de cliquet contre la dent de came du clip élastique de verrouillage.

Title: Fiber optic methods of lighting sculptured acrylic
Inventor: VANN JAMES S
IPC: G02B6/00
Filed: 1996-09-17
Abstract: Typically acrylic is lighted by grouping end portions of a multiplicity of light transmitting fiber optic cables together to form a desired shape or pattern.          The problem with this approach is that because so many cables are required, it is difficult, time consuming, and relatively expensive. This invention discloses three artistic and novel methods of light sculpturing acrylic with fiber optic cable.  In one method an elongate channel is carved on a rear side portion of the acrylic; a front side portion of the channel is colored;  and one end portion of a fiber optic cable is laid in and secured along the length of the channel.  In a second method a rearwardly extending post is mounted on a rear side portion of the acrylic;  and one end portion of the fiber optic cable is secured to the top portion of the post, so that light transmitted through the cable disperses over an area to one side of the post.  In a third method the rear side portion of the acrylic is painted and a shape is carved thereon.  The shape is then covered with an end of a clear plastic post.  A cable accepting hole is drilled in the other end of the clear post and one end of the fiber optic cable is secured therein.  In each method a conventional light source is applied to the other end of the fiber optic cable.

Title: Tank-filling shut-off valve
Inventor: GRAYSON JOHN R
IPC: F16K31/20
Filed: 1997-02-04
Abstract: A valve mechanism for supplying liquid to a container until the surface of the liquid reaches a predetermined level includes a valve body disposable in the container and defining a cavity, an inlet port for communication with a liquid source and an outlet port communicating with the interior of the container.  A valve seat is provided in the cavity adjacent to the outlet port, and a valve member in the shape of a ball is disposed within the cavity and moveable between a normal closed condition and an open condition relative to the valve seat for respectively closing and opening the outlet port.  A guide tube depends from the valve body in communication with the outlet port and has a float coupled to it.  A valve actuator includes a base seated in the container and a rod extending upwardly therefrom into the guide tube.  The actuator rod is engageable with the valve member for holding the valve member in its open condition when the surface of the liquid in the container is below the predetermined level.  The actuator withdraws from the outlet port to also allow the valve member to move to its normal closed condition when the surface of the liquid in the container is at or above the predetermined level.

Patent CA-2202433-A1 (CA)
Inventor: TAZARTES DANIEL A
IPC: G01C19/72
Filed: 1997-04-11
Abstract: A phase modulator applies sequences of artificial phase shifts in the region of overmodulation between light beams counterpropagating within the sensor coil of a Sagnac interferometer to obtain improved random walk performance.  The sequences are composed of phase shifts of ~a.pi./2b and ~(4b-a).pi./2b where a is an odd integer and b is an integer greater than 1.  The waveform for driving the phase modulator is derived from a 2.pi. radian mapping plotted so that adjacent driving signal values differ by a.pi./2b or -(4b-a).pi./2b in a first angular direction and by -a.pi./2b or by (4b-a).pi./2b in the opposite angular direction.  Angular transitions about the mapping may be predetermined to generate a deterministic, random, or pseudo-random modulation sequence.  In the event that a deterministic sequence is chosen, it is examined for orthogonality properties to assume zero average output bias from crosstalk.
