Filed: 1991-04-17
Abstract: -IMMUNOREAGENT COMPOSITION, TEST KIT AND   RAPID ASSAY FOR HUMAN CHORIONIC GONADOTROPIN             Abstract of the Disclosure A rapid immunometric assay for human chorionic gonadotropin (hCG), commonly used for detection of pregnancy in human females, has been developed using a specific wash solution and conjugate level which reduces background and improves sensitivity.  The assay can be carried out within about two minutes using a microporous membrane to capture the "sandwich" complex of antigen and two antibodies, one of which is located on the membrane. Greater sensitivity at low levels of hCG have been demonstrated so the assay is useful as an early indicator of pregnancy.  An immunoreagent composition and test kit are provided for use in the assay.

Inventor: VOERMAN MICHAEL J
IPC: C05D9/02
Filed: 1991-05-15
Abstract: This invention provides a selenium composition that may be applied to pastures and soils to treat selenium deficiency in soils, plants and grazing animals. Known formulations use either sodium selenate or barium selenate in a slow release form. However these known compounds either are not sufficiently long-lasting or cannot rapidly boost selenium levels in pastures. These problems have been overcome by an agricultural composition that has an effective amount of a mixture of barium selenate in a slow release form and a water soluble selenium compound. The ratio, on the basis of elemental selenium, of water soluble selenium compound to barium selenate is between 10:90 and 30:70. The composition is able to provide a selenium boost and maintain selenium levels in pastures for long periods.

Title: Vehicle seatbelt having an integral airbag
Inventor: CAMERON ROBERT W
IPC: B60R21/268
Filed: 1991-05-16
Abstract: ABSTRACT     A passenger restraint system for vehicles.  A pouch containing an inflatable restraint hag is mounted to a seatbelt so that the pouch is positioned in front of a passenger when the belt is worn.  There is an opening in the forward side of the pouch for permitting the bag to expand out of the pouch upon inflation.  A flexible hose provides a conduit for supplying compressed air to the inflatable bag from a compressed air cylinder mounted to the vehicle body.  A valve permits the air to flow from the cylinder through the hose to the bag in response to an impact received by the vehicle, so that the bag inflates and restrains the passenger against forward motion.  The bag may be made of KevlarTM, or may be provided with KevlarTM facings.  The valve may be a lid positioned in the neck of the air bottle and held place by a pin and a hinge.  The pin may be withdrawn by a solenoid actuated by a deceleration sensor so as to release the lid.  Alternatively, an actuating member positioned in a bore may strike an end of the actuating member in response to the impact so as to move the actuating rod forward and out of the receptacle.

Title: Audio routing within trunked radio frequency multisite switch
Inventor: GULLIFORD PHILIP C
IPC: H04W84/08
Filed: 1991-08-27
Abstract: A distributed trunked radio freequency (RF) switching network (switch) distributes audio routing control and processing throughout the switch, thus avoiding a centralized mixing matrix, increasing fault tolerance and providing low routing request latency time. Each audio source (e.g., RF repeater transmitter, dispatch console microphone) is preassigned an audio channel on a time division multiplexed (TDM) digitized audio network or bus.      The audio sources continually broadcast digitized audio signals to all other nodes over the TDM network. Audio routing is performed at the audio destinations (e.g., nodes associated with RF repeater receivers, dispatch console speakers) by selectively "listening" to active TDM network channels. In the preferred embodiment, audio is routed unidirectionally on an "as needed" basis (e.g., in response to radio transceiver "keys" and "unkeys"), and audio routing pathways may change dynamically during an on-going call.

Title: Medium consistency ozone bleaching
Inventor: HENRICSON KAJ
IPC: D21C9/153
Filed: 1992-04-08
Abstract: ABSTRACT      In a method of bleaching medium consistency pulp with ozone using a mixer, ozone containing gas and about 6-15% consistency pulp are fed to the mixer, and then discharged in a first, preferably vertical, path.  The mixture of pulp and ozone moves in a first part of the vertical path a time period of about 1-5 seconds at a velocity of about 1-5 m/s so that the gas and pulp do not separate during movement in this first part, and the vast majority of the pulp brightening reaction between the ozone and pulp takes place.  This is preferably accomplished by passing the mixture upwardly in a small diameter conduit having a height of about 3-20 meters.  Then the velocity of the pulp is slowed while still moving in the first path, preferably by feeding it directly to a much larger diameter (e. g. 1.5-10 times) conduit, so the height of the unit may be kept under 100 feet.  The pulp flows in the large diameter conduit for about 0.5-5 minutes so that residual reactions take place.
