Title: Interference suppression in optical communication systems
Inventor: WOOD THOMAS H
IPC: H04B10/43
Filed: 1990-12-11
Granted: 1995-02-14
Abstract: A technique for suppressing mutually induced interference between spatially separate channels which are positioned nearby one another during a first portion thereof to cause interference therebetween, and are positioned relatively far from one another during a second portion thereof to avoid mutually induced interference therebetween. Energy in one of the channels is converted to a signal which is distinguishable by code, frequency, or time, from energy in the other channel. The converted signal is then transmitted in the second portion of one of the channels. Then, any interference in the other channel caused by the converted signal can be suppressed by suppressing the distinguishable energy from the converted signal.

Patent CA-2055153-C (CA)
Inventor: VAN OOIJ WIM J
IPC: C23C28/00
Filed: 1991-11-07
Granted: 2002-03-05
Abstract: Steel sheet coated with a nontoxic, relatively insoluble, inorganic, corrosion resistant coating. A silicate coating is formed on a steel sheet by rinsing the sheet for at least 30 seconds in an alkaline aqueous solution containing 0.005 M silicate, 0.005 M metal salt and having a temperature of at least 25ÀC. The sheet is dried to form an adherent silicate coating having a thickness of at least 2 nm prior to being treated with an aqueous solution containing 0.5-5 vol.-% silane. If the sheet is painted, the silane film forms an adherent bond between the paint and the silicate coating. A silane treated silicate coating minimizes red rusting on terne coated steel by sealing pin holes.  A silane treated silicate coating also provides good corrosion protection and paint adherence on cold-rolled or galvanized steel.

Title: Broadband microstrip to slotline transition
Inventor: THOMAS MIKE D
IPC: H01Q13/08
Filed: 1992-09-21
Granted: 1997-05-27
Abstract: A broadband transition between microstrip transmission line and slotline transmission line.  The geometry of inte-grating the two transmission lines results in a broadband microstrip shunt circuit across the slotline, and a broad-band slotline  open circuit in the direction opposite of propagation on the slotline.  This produces direct coupling between the two transmission lines.  The transition does not  require  any  intermediate  transmission  line  types between the microstrip and slotline,  and no  frequency dependent  tuning  stubs  are used  to produce the  shunt circuits and open circuits required for coupling.   The result is a broadband transition which can be fabricated using standard etching techniques and requiring no plated through holes.

Granted: 2002-02-19
Abstract: A food freezer'(10) having a mechanical refrigeration system (54) comprising first (56) and second (58) closed-loop fluid circuits, wherein the first fluid circuit (56) employs carbon dioxide as its refrigerant and transfers heat to the second fluid circuit (58), which in turn transfers heat to the environment or to another fluid circuit. In the first fluid circuit evaporator (60), carbon dioxide is maintained at pressures between 60.4 psig and 120 psig. In a preferred embodiment of the invention, the freezer (10) employs at least two separate blowers (44); (86) or fans for circulation of air or other gas in the freezer enclosure. One blower/fan (44) operates continuously to maintain circulation of cold air or gas in the freezer (10). The other blower/fan (86) operates inter-mittently or at variable speeds to vary air flow across the evaporator (60), and thereby increase or decrease heat transfer from the freezer (10) interior to the first fluid circuit evaporator (60) to maintain the freezer (10) interior at a desired temperature or within a desired temperature range.
