Patent CA-2134989-A1 (CA)
Inventor: MILLER THOMAS L
IPC: G05D22/02
Filed: 1994-11-03
Abstract: A humidifier system includes a spray apparatus in a housing which sprays a mist of water droplets onto a mist eliminator to intercept the mist of water droplets.  The mist of droplets is captured in a liquid phase by the mist eliminator and is substantially completely converted into a vapor phase in the form of increased humidity in the air stream.  A humidity sensor located downstream of the mist eliminator senses the humidity of the stream of air.  A controller controls the quantity of water sprayed in response to the humidity sensed to maintain a predetermined humidity in the humidified stream of air.  A second humidifier includes a heater which creates a region of intense heat to instantaneously evaporate water mist directed thereon in a stream of air.  In a third embodiment, water and pressurized air are simultaneously injected into a region of intense heat.  The pressurized air rapidly expands within the region of intense heat and thereby adds energy to the system to ensure virtually complete evaporation of the water.

Title: Deletion mutants as vaccines for cholera
Inventor: MEKALANOS JOHN J
IPC: A61P31/04
Filed: 1993-07-01
Abstract: The invention features of nontoxigenic, genetically stable mutant strains of V  cholerae and a method of making which are useful as live, oral vaccines for inducing immunological protection against cholera. The mutant strains are genetically engineered mutants which lack DNA encoding a functional ctxA subunit which is responsible for many of the symptoms of cholera. The strains also lack any functional attRS1 sequences which are required for recombination and amplification of the CTX genetic element. These strains are safe because they can not recombine with the wild type attRS1-containing vehicles which include the ctxA-encoding DNA.
Patent CA-2142235-A1 (CA)
Inventor: FERGUSON PATRICK L
IPC: G06F7/00
Filed: 1995-02-10
Abstract: A FIFO queue is utilized to provide control information to the appropriate time slot in a time multiplexed serial link between an interface chip and a CODEC.  The FIFO queue allows rewriting or replacement of any control registers present in the queue without requiring that a new entry be placed in the queue.  A particular control register which is placed in the queue then maintains its place as the queue is emptied, even though the control register may be written one or more times while the control register entry is in the queue waiting for transmission to the CODEC.  The loss of the prior command information is not a problem as the data rate of the serial link is still sufficiently high so that any minor transitory change which may have been desired would be of minimal effect in any regard and would have been inaudible to the human.
