IPC: A62B18/10
Filed: 1993-04-21
Abstract: An exhalation valve (14) for a filtering face mask (10) has a flexible flap (24) that makes contact with a curved seal ridge (30) of a valve seat (26) when the valve (14) is in the closed position. The curvature of the seal ridge (30) corresponds to a deformation curve exhibited by the flexible flap (24) when secured as a cantilever at one end and exposed at its free portion to a uniform force and/or a force of at least the weight of the free portion of the flexible flap. A seal ridge curvature corresponding to a flexible flap exposed to uniform force allows the flexible flap (24) to exert a generally uniform pressure on the seal ridge to provide a good seal. A seal ridge curvature corresponding to a flexible flap exposed to a force of at least the weight of the flap's free portion allows the flexible flap (24) to be held in an abutting relationship to the seal ridge (30) under any static orientation by a minimum amount of force, thereby providing a face mask (10) with an extraordinary low pressure drop during an exhalation.

Patent CA-2144877-A1 (CA)
Inventor: MCINERNEY PETER J
IPC: G06F9/44
Filed: 1994-01-06
Abstract: A human oriented object program-ming system provides an interactive and dy-namic modeling system to assist in the in-cremental building of computer programs which facilitates the development of com-plex computer programs such as operating systems and large applications with graphic user interfaces (GUIs). A program is mod-eled as a collection of units called com-ponents. A component represents a single compilable language element such as a class or a function. The three major function-alities are the database, the compiler and the build mechanism.  The database stores the components and properties. The com-piler, along with compiling the source code of a property, is responsible for calculating the dependencies associated with a  compo-nent. The build mechanism uses proper-ties of components along with the compiler generated dependencies to correctly and ef-ficiently sequence the compilation of com-ponents during a build process.

Title: Cableless governor control
Inventor: LAWRENCE MICHAEL E S
IPC: F02B1/04
Filed: 1995-04-05
Abstract: A device for controlling the engine speed of a gasoline-engine  -   driven pressure washer comprises a cylinder having a machined bore which houses a piston, piston spring, and a connecting rod with a drag nut.  The cylinder is mounted on the gasoline engine in such a manner that the movement of the piston and connecting rod effect the movement of the engine governor arm, thus controlling the speed of the engine. A hydraulic line connects the cylinder to the pressure washer.          When the trigger shutoff gun is closed, the pressure washer system pressure falls to near zero, and the spring forces the piston and connecting rod back into the cylinder such that the drag nut contacts the engine governor arm, drawing it back and thereby slowing the engine.          When the trigger shutoff gun is opened, the resultant rise in pressure is transmitted to the piston, forcing it back against the spring, extending the connecting rod and releasing the governor arm, thus allowing the engine speed to increase to its throttle setting. The opening and closing of the trigger shutoff gun in the pressure washer system causes the hydraulic line to be pressurized or de-pressurized, causing the piston to move back and forth in the cylinder.

Title: Security grill lock assembly
Inventor: RUOSS PETER ANTON
IPC: E05F3/00
Filed: 1995-04-19
Abstract: Locks for security grills used on doors or windows tend to be structurally complicated, and consequently expensive to produce and/or install.  A relatively simple lock assembly for use with a  security grill includes a box for mounting on one edge of a grill, a slot in one side of the box for opposing the frame of the door or window when the grill is closed, a plate for mounting on the outside of the frame in opposition to the box, whereby the plate completely covers the slot when the grill is closed, a bolt extending through the plate for rotatable mounting in the frame in alignment with the slot, an ear on the outer end of the bolt for insertion through the slot into the box when the grill is moved to the closed position, and a handle on the inner end of the bolt for rotating the latter between a release position in which the ear can be inserted into or removed from the box via the slot and a locked position in which the ear is retained by a projection in the box.  By providing a helical spring in a sleeve extending into the frame from the sleeve and outwardly against the slot containing side of the box, the box is biased outwardly to increase the locking effect of the projection on the ear.

Title: A speech recognition system
Inventor: STRONG ROBERT DON
IPC: G10L15/193
Filed: 1993-12-29
Abstract: Maintaining dynamic categories for speech rules in a speech recognition system which has a plurality of speech rules each comprising a language model and action. Each speech rule indicates whether the language model includes a flag identifying whether the words in the language model is dynamic according to changing data in the speech recognition system. At periodic intervals, such as system initialization or application program launch time, for each flag in each speech rule which indicates that words in the language model an dynamic, the words of each of the language model(s) are updated depending upon the state of the system. Concurrent with the determination of acoustic features during speech recognition, a current language model can be created based upon the language models from these speech rules. Also, speech rules are partitioned according to the context in which they an active. When speech is detected, concurrent with acoustic feature extraction, the current state of the computer system is used to determine which rules are active and how they are to be combined in order to generate a language model for word recognition. Also, partitioning speech recognition rules for generation of a currant language model and interpretation in a speech recognition system is described. Rapid and efficient generation of a language model upon the detection of a current context at a second interval (e.g. upon the detection of speech in one embodiment) then may be performed.

Patent CA-2160931-A1 (CA)
Inventor: SCHURYK JERRY
IPC: A01K97/10
Filed: 1995-10-19
Abstract: This invention is known as a Fishing Pole Holder.  It is designed for the purpose of anchoring and holding a fisherman's angling rod in an upright position after he has cast his line into the water. The fisherman can then leave his rod unattended. This device is designed for a dual function. It not only holds an angler's rod in the required position on a lakeside or riverbank it also is utilized as a device to store this fishing rod when it is not being used. This simple mechanism consists of a section of hollow tubing with a retention liner at one internal diameter end and a reversible housing assembly, containing a ground spike and storage hook, which is inserted onto the opposing end of the tube. When the unit is being activated as a fishing rod holding device, the housing is inserted onto the external diameter of one end of the tubing in such a manner that the ground spike is allowed to protrude. This spike is inserted into the ground at the required distance from the water. Into the opposite end of the tubing the handle of the fishing rod is inserted. When the unit is being activated in the storage mode the housing is removed from the tube and re-inserted onto the tube so that the hook end protrudes. This allows the fishing equipment to be hung in a vertical manner. At the opposite end of the tubing the knob end of the fishing rod is inserted into the retention liner which secures the rod in the tube. This allows the storage of the angling rod, by means of the hook, into an upright position.

Filed: 1994-08-30
Abstract: A method for the rapid estimation of hyperplastic and hypertropic changes in animal airways is an assay which specifically measures acidic and neutral mucoproteins in a linear fashion from 0.5 µg to at least 10 µg. The assay comprises exposure of a test animal to a suspected metaplastic inducer, removal of the lungs, homogenization in an appropriately buffered solution containing reducing agents and protease inhibitors removal of particulate matter, and size-fractionation of the SDS treated soluble extract. The high molecular weight material is immobilized and stained for either acidic or neutral mucosubstances and the specific staining is quantitated. The changes observed are consistent with those seen in histological sections of the exposed tissues. The assay is useful in confirming the metaplastic potential of suspected compounds, in determining what neurohumoral mediator(s) are involved in mucus cell metaplasia in animal models for chronic obstructive pulmonary disease, and in identifying compounds which might ameliorate these effects.

Title: Method for the preparation of urea
Inventor: JONCKERS KEES
IPC: C07C273/04
Filed: 1996-05-21
Abstract: The present invention relates to a process and apparatus for the preparation of urea, and in particular for urea obtained from ammonium carbamate formulated from carbon dioxide and ammonia at a pressure of about 125 bar to about 350 bar in a urea synthesis solution in a urea reactor. The reactor defines a horizontally arranged condensation zone and contains a heat exchanger. According to this process, NH3 and CO2 are supplied to the reactor and are largely absorbed into the urea synthesis solution. A substantial portion of the heat formed in the condensation is discharged by means of the heat exchanger. The residence time of the urea synthesis solution in the reactor preferably is selected so that at least about 85% of the theoretically obtainable amount of urea is prepared. Thereafter, the urea synthesis solution can be processed into a urea solution or solid urea.
