Patent CA-2133835-A1 (CA)
Title: Flue gas conditioning system
Inventor: WRIGHT ROBERT A
IPC: B03C3/14
Filed: 1993-04-05
Abstract: 2133835 9319852 PCTABScor01 A flue gas conditioning system (10) features a self-contained sulfur burner control loop (43) that operates to maintain a constant desired temperature supply of sulfur dioxide in air by varying the rate of supply of sulfur fuel (41) to the sulfur burner (42), and the absence of device in the sulfur flow path to measure or monitor sulfur flow rate. In some embodiments, a flue gas conditioning agent demand control apparatus (224) is incorporated into the system for controlling a flow of conditioning agent based on a signal determined from a rate of discharge of a charged electrode of the electrostatic precipitator (20). Also, in some embodiments of the invention, the system uses a catalytic converter movable (figure 10 item 322) between an operative position where the flue gas flows through one or more converters to convert SO2 contained in the flue gas to SO3 when conditioning agent is needed and an inoperative position where the flue gas does not flow through the catalyst when conditioning agent is no longer needed.

Abstract: Aqueous latices adapted to forming visi-ble light transparent, coherent polymeric films, e.g. in laminates, as protective coatings or as adhesives, comprising colloidal particles of a UV-absorbing polymer less than 5 micrometers in diameter. Useful UV-absorbing polymer in-clude homopolymers and copolymers of vinyl-functionalized monomer of benzotriazole or benzophenone and mixtures with plasticizer and/or coalescing agent. Plasticizer and coales-cing agents are useful for providing polymer with reduced glass transition temperature to fa-cilitate coalescence of polymer particles into co-herent films. Useful additives for the latices of this invention include wetting agents, surfact-ants, and crosslinking agents, anti-oxidants and radical scavengers. The latices of this invention are particularly useful in providing clear, thin coatings on windows, tags, labels, flooring, tents, awnings, containers and other UV-sus-ceptible substrates.

Patent CA-2141390-A1 (CA)
Title: Method for measuring a resistance value
Inventor: VERHAART HENRICUS F A
IPC: G01R27/08
Filed: 1995-01-30
Abstract: The invention relates to a method for measuring a resistance value in a network incorporated in an electri-cal apparatus, wherein the network has at least two accessible terminals, the network has at least two time constants differing mutually by at least one order of magnitude, and the resistance value can be related to the voltage applied to the terminal clips and the current flowing through the apparatus.      Such control switches are poorly accessible.   Direct measurement is time-consuming as a result of the large value of the time constants. These problems are diminished by applying a step-like change of the voltage to the terminal clips, measuring the current flowing through the terminal clips before the change has taken place and after the transient phenomenon related to the smallest time constant and caused by applying the change is damped, and calculating the first resistance value from the measured values of the current.

Title: Device for Assisting and Maintaining Penile Erection
Inventor: COATES GRAHAM
IPC: A61F5/41
Filed: 1993-09-13
Abstract: A penile engorgement valve has a looped rod (1) with an arcuate center section (2) positioned on a top base surface of a male penis (3). Opposite side sections (5) of the looped rod are extendable arcuately at opposite sides of the male penis and juxtaposed at a fulcrum curve (6) in each of the opposite side sections. A lever arm (7) is extended from the fulcrum curve in each juxtaposed side section and attachable to a tension member (11). The tension member is anchored to a hip section and rearward of a user. Tension from the tension member is applied to the lever arms in a direction towards the hip section of the user. The tension results in pressure on the fulcrum curves and on the arcuately looped center. Blood flows into the penis in arteries (16) and returns in flow out from the penis in veins (15) at the top of the penis in a pubic area (4) where the arcuately looped center is positioned and at opposite bottom sides of the penis in a perineal area (8) where the fulcrum curves are positioned. Flow of blood out from the penis is restricted relatively more than flow of blood into the penis by a valvular effect resulting from relatively greater collapsibility of the veins than of the arteries from the pressure applied. This enhances penile engorgement and turbidity for sexual intercourse. Pressure adjustment and cushioning on of the looped rod are included.

Title: Medication filled syringe equipment
Inventor: NAGANUMA MASATERU
IPC: A61M5/178
Filed: 1994-03-01
Abstract: A first object of the invention is to insure that medication filled syringe equipment can be kept sterile at all stages until use, is protected against malicious unauthorized use, can be packaged in a simpler way and can protect the medication to be in a stable form.  A second object of the invention is to insure that an additional liquid such as an anesthetic, another medication in liquid form or a solubilizer can be aspirated by medication filled syringe equipment in an aseptic appropriate manner before injection.  To attain these objects, the equipment of the invention comprises barrel 1, needle attaching portion 2 fitted with cap 11, plunger rod 22, and sealing device 31 as tube 32 of a heat-shrinkable film that is slipped over the area from the cap 11 through the barrel 1 to the basal head 23 of the plunger rod 22.  The sealing device 31 is then caused to shrink thermally so that it will adhere closely to those members, thereby insuring that the barrel 1 filled with medication 5, plunger 21 and plunger rod 22 are isolated from ambient air.  At the same time, the barrel 1 in which the medication 5 has been contained by the plunger 21 in a predetermined position in cooperation with the cap 11 is provided with marking 3 that is put within the area between the front and rear ends of the plunger 21 to indicate the limit beyond which the plunger 21 should not be withdrawn.

Title: Flash memory mass storage architecture
Inventor: ASSAR MAHMUD
IPC: G06F12/02
Filed: 1994-03-23
Abstract: A semiconductor mass storage sys-tem (100) and architecture can be substi-tuted for a rotating hard disk. The system and architecture avoid an eras cycle each time information stored in the mass stor-age is changed. Erase cycles are avoided by programming an altered data file into an empty mass storage block (step 202-206) rather than over itself as hard disk would. Periodically, the mass storage will need to be cleaned up (step 204). Secondly, means are provied for evenly using all blocks in the mass storage (Fig. 7). These advan-tages are achieved through the use of sev-eral flags (200), a map to correlate a logical address of a block to a physical address of tDat block (308, 408) aDd a count regis-ter for each block. ln particular, flags are provided for defective blocks (118), used blocks (112), old version of a block (104, 116), a count to determine the number of times a block has been erased and written and erase inhibit flag (200).
