Title: Paint gun incorporating a laser device
Inventor: BAUER RICKY JAY
IPC: G01B11/02
Filed: 1998-09-30
Abstract: A spray gun for applying a liquid spray coating, such as paint, to a surface incorporates a light source system for gauging the position of the spray gun relative to a worksurface in order to optimize application of the coating to the surface.  The light source is preferably in the form of a laser which emits a pair of light beams toward the worksurface.   The pair of light beams converge toward each other in a direction toward the surface, and the position of the beams on the surface is used by the operator to judge the distance of the spray gun from the surface. An adjustment mechanism is interconnected with one of the light beam sources, so as to adjust the point of convergence of the light beams. A  closable door is associated with the spray gun housing at one of the light beam emitting locations, to selectively prevent emission of one of the light beams from the spray gun, such that a single light beam is emitted from the spray gun for use as a reference for spot application of the coating to the surface.

Title: Method for fabricating silica glass
Inventor: OH JEONG-HYUN
IPC: C03B20/00
Filed: 1998-08-28
Abstract: A silica glass fabrication method. The method includes the steps of adding silica and a dispersant to a premix solution obtained by dissolving a monomer for acrylic resin and a cross-linking agent in a distilled water, and dispersing themixed solution, and adjusting the pH of the mixture, to form a sol; removing airbubbles from the sol, and then aging the sol; adding a polymerization initiator to the aging-treated sol, and adjusting the pH of the reaction mixture; pouring thereaction mixture into a mold, aging the mixture in an incubator at a high temperature and then gelating the resultant; aging the obtained gel, demolding the aging-treated gel, and then drying the demolded gel; thermally-treating the dried gel to remove organic substances from the gel; and performing a hydroxy group elimination reaction and a sintering reaction on the gel from which organic substances have been removed. Therefore, a high purity silica glass tube, in which cracking after drying scarcely occurs and shrinking ratio is markedly low, can be obtained. Also, a large silica glass tube can be manufactured by this fabrication method.

Title: Faulty filter detection technique
Inventor: ESLAMBOLCHI HOSSEIN
IPC: G01R31/08
Filed: 1998-10-22
Abstract: To locate a defective one of filter/voltage arresters (20 1, 20 2, 20 3, 20 4,... 20n-1), each associated with a corresponding one of splice cases (18 1,18 2, 18 3, 18 4,... 18n-1) on a buried fiber-optic cable (10), an operator employs a locating apparatus (24) to detect the presence of an AM signal within a prescribed frequency range that is radiated when the filter/voltage arrester becomes defective. By determining the location along the cable where the AM signal has its greatest strength, the operator can accurately establish the location of the defective filter/voltage arrester, thereby avoiding unnecessary excavation of each splice case.

Title: Dynamic network configuration of a one-way adapter using a proxy agent that communicates with the resource server through a configured return path adapter
Inventor: LALWANEY POORNIMA
IPC: H04N21/658
Filed: 1998-11-09
Abstract: A one-way adapter such as a cable modem is initialized to allow a personal computer to receive data from a computer network such as the Internet via a broadcast channel, while transmitting data upstream to the computer network via a telephone line.  First, a two-way adapter such as a phone modem is initialized by establishing a telephone link with a terminal server of an Internet Service Provider telephone network.  The terminal server obtains an IP address from a phone network address server, and assigns the IP address to the phone modem stack.  Next, the cable modem stack sends out a request for session initialization to a cable modem driver.  The request is processed by a packet processing relay agent (PPRA), and the IP address of the phone modem is inserted into the packet.  The IP packet destination address is set to that of a cable network address server.  A cable network address server receives the packet via an upstream telephone line and responds with IP address and configuration information for the relay agent address.  The phone modem receives the response and passes it to the cable modem stack via the PPRA.  The cable modem is thus initialized with IP address and configuration information and is ready to receive Internet data via a one-way RF channel.
Patent CA-2253208-A1 (CA)
Inventor: BARROWS RICHARD C
IPC: F25B41/04
Filed: 1997-11-12
Abstract: A refrigeration system (10) which controls subcooling by controlling the amount of refrigerant diverted from the condenser (14) to the receiver (16) based upon the difference in temperature between the phase change transition temperature of the refrigerant in the condenser (14) and the liquid refrigerant temperature at the condenser output.  Refrigerant is bled from the receiver (16) to charge the system until the condenser pressure causes the difference between the phase change and liquid temperatures to exceed a predetermined value. A controller (100) responds to this condition by simultaneously operating a bleed valve (32) at the receiver inlet (34) and a release valve (56) at its outlet to draw refrigerant from the condenser (14) into the receiver (16). As the condenser pressure drops, the difference between the phase change and liquid temperatures decreases toward the desired amount, and the cycle begins again.
