Title: Expandable urethral plug
Inventor: MCLAUGHLIN PAUL D
IPC: A61F2/00
Filed: 1994-05-17
Abstract: A urethral plug (10) possessing a contracted diameter for insertion and removal through the orifice of the urethra, and a larger, expanded diameter for blocking the flow of urine in the urethra, bladder neck and bladder. In a first embodiment, the plug (10) comprises a cooperating housing and inner member lying in coaxial engagement.  A larger diameter is achieved by mechanical deployment of the inner member, resulting in the changing of the shape of the housing, or in another embodiment, the changing of the shape of the inner member. In a further embodiment the urethral plug comprises a housing comprised of material which undergoes automatic expansion when exposed to temperature.

Title: Anti-jackknife device
Inventor: FREW JOHN
IPC: B62D53/08
Filed: 1995-12-05
Abstract: An arrangement for use in preventing a tractor trailer from jackknifing.  The present invention, in its broadest context, includes a pair of pneumatic or hydraulic cylinders which are positioned within the forward portion of the trailer.  When a dangerous situation is encountered by the operator of the tractor trailer, the cylinders are actuated.  Actuation of the cylinders results in a rod extending from each of the cylinders.  These rods, when actuated, extend through a trailer plate and into apertures formed within the fifth wheel of the tractor.  In this way the tractor trailer is prevented from jackknifing.

Patent CA-2182427-A1 (CA)
Inventor: GALLER BRUCE I
IPC: H04N7/173
Filed: 1996-07-31
Abstract: Verifying that a correct program is being received and displayed on a television set of a consumer. In addition, video quality is checked to assure that transmission has not degraded the video quality. When the consumer requests a program by transmission of a message via a controller in a set top box to a system computer controlling a cable television system, the system computer sends the necessary commands to cause the requested program to be communicated to the consumer site and also transmits to the controller in the set top box a start time of the requested program and information defining the initial video content of that program. At the start time, the controller verifies that the initial video content is being received and that the consumer has the set top box correctly tuned. The controller uses aframe grabber circuit at the consumer site to grab the initial portion of the program and then to analyze the stored portion with respect to the initial video content. If the stored portion is not the same as the initial video content, the controller transmits an error message to the system computer. In response to the error message, the system computer corrects the switching or transmission problem so that the correct program is being sent to the consumer site. The system computer then verifies that the correct program is being received.

Abstract: This invention relates to power generating systems, particularly those used in large power plants used to generate electricity, including both coal fired and nuclear power plants. In electrical power plants that use thermal energy (coal, oil, gas or nuclear fuel) to generate electricity efficiency is about 40%. A lot of energy is lost in the condenser.      Efficiency               Energy lost in the condenser 45%                         38% 40%      41% 35%                         48% 32%                         48% In the rankine cycle we need a condenser to condense steam into liquid water. In that process we use water from environment (lake, river or ocean) or air to cool steam.          During that process thermal pollution is created. With this invention half of thermal energy lost in the condenser could be put back into rankine cycle.

Title: Fabrication of sub-micron silicide structures on silicon using resistless electron beam lithography
Inventor: LAVALLEE ERIC
IPC: H01L21/44
Filed: 1997-02-12
Abstract: A method for fabricating a sub-micron structure of etch-resistant metal/semiconductor compound on a substrate of semiconductor material comprises the step of depositing onto the substrate a layer of metal capable of reacting with the semiconductor material to form etch-resistant metal/semiconductor compound, and the step of producing a focused electron beam. The focused electron beam is applied to the layer of metal to locally heat the metal and semiconductor material and cause diffusion of the metal and semiconductor material in each other to form etch-resistant metal/semiconductor compound. The focused electron beam is displaced onto the layer of metal to form the structure of etch-resistant metal/semiconductor compound. Finally, the layer of metal is wet etched to leave on the substrate only the structure of metal/semiconductor compound. Following wet etching of the layer of metal, an oxygen plasma etch can be conducted to remove a carbon deposit formed at the surface of the structure of etch-resistant metal/semiconductor compound.      Also, the substrate may be subsequently etched to remove a thin layer of metal rich semiconductor material formed at the surface of the substrate by reaction, at room temperature, of the metal and semiconductor material with each other.

Abstract: A management system (A1) provides a remote access service to units of equipment at distributed locations of a communications network (A4). For instance, it can provide automatic meter reading over a PSTN for utility companies (A5). The management system (A1) initiates calls over the network (A4) to selected units, usually pre-determined, in response to call requests, and can provide considerable functionality such as authentication and batch processing of the request. Conflict with ordinary traffic on the network (A4) can be avoided by monitoring for ordinary traffic calls and clearing down any existing conflicting remote access calls or blocking any requested potentially conflicting remote access calls. Uncompleted or blocked remote access calls are automatically re-scheduled by the management system (A1).

Title: Muzzle loading gun and adaptor
Inventor: JOHNSTON KENNETH E
IPC: F41C9/08
Filed: 1997-04-08
Abstract: An adaptor (10) which allows a standard cartridge firing action to be used with a black powder muzzle loading gun (100) is described. The adaptor includes an insert (12) and a nipple (16) and is configured to be inserted into the barrel (108) of the gun adjacent the receiver (104). In use, a standard rifle cartridge casing (150) with a wall (150A) and with a head (150B) at one end containing a primer (152) is loaded into the receiver of the gun. Next, the cartridge casing is moved into the end (108A) of the barrel such that the casing extends into the center bore (14) of the insert and the nipple extends into the inside of the casing. When the gun is fired, the firing pin (114A) contacts the primer which ignites the black powder (118) which expels the projectile (120) from the gun. The ignition of the primer causes the wall of the casing of the cartridge to expand. The casing expands such that the casing is force fit and tightly held in the center bore of the insert. The expansion of the wall of the casing prevents blow back from the explosion from escaping past the adaptor and into the receiver of the gun.

Title: Inflatable combination cargo packing bag
Inventor: KING GREGORY S
IPC: B60P7/06
Filed: 1997-04-08
Abstract: An inflatable dunnage bag is comprised of a first and independently sealed bag that is inserted within a paper tube before the tube ends are sealed to form a second, independent bag. The combination of an inner bag within an outer bag provides increased bursting strength compared to similar ply bags created as only a single bag. The combination bag is much easier to construct since at least two plies of paper that are pressed to form the inner bag are no longer part of the bag end folding and sealing process. This is especially true if the outer bags ends are sealed by stitching them together.
