Title: Game table
Inventor: FOX IRVING
IPC: A63F7/06
Filed: 1995-02-01
Abstract: A game table relating to a game where the object is to sink a ball or balls in holes includes a flat surface having several holes spaced around the periphery of the surface. Elastic material is connected to the periphery of the surface and projects upwardly from the surface so as to deflect a ball which makes contact with the elastic material. Two sets of obstacles on the surface impede the path of the ball. One set of obstacles includes pairs of pegs near each hole. An elastic band can be placed around a particular pair of pegs so as to both deflect a ball and prevent the ball from entering the hole. Alternatively, the elastic band can be removed from one or more holes so as to permit a ball to enter such holes.          Another set of obstacles is located closer to the centre of the surface and is preferably a number of pegs arranged in concentric circles having the middle of the surface as their centre.

The threat sensor data fusion control process (302) also determines whether missile approach detector data (48) is sent to a countermeasures analyzing apparatus (326). The threat ambiguity detector (308) provides ambiguity data (340) to a threat ambiguity resolving apparatus (324). The radar emitter ID conversion apparatus (310) provides converted jammer data (342) to a functional sensor back-up apparatus (201). The radar emitter ID conversion process (310) receives a common radar emitter (ID) data base (312). The threat sensor data fusion process controller (302) also provides fusion process control (338) to the complementary threat data apparatus (322). Complementary threat data (332) is provided to the pilot through various presentation methods and to the jammers (34, 36) for electronic countermeasures. Also, threat ambiguity resolution data (334) is provided and back-up data (228, 230) is provided. The presentation methods include video (224) and voice (226) and a tactical electronics countermeasures command (330) is automatically initiated.

Patent CA-2154415-A1 (CA)
Title: Method of transporting and applying a surface treatment liquid using gas bubbles
Inventor: TENCH D MORGAN
IPC: B05D3/00
Filed: 1995-07-21
Abstract: A method is provided for dynamically transporting and applying a liquid to a surface, such as the bottom surface of a printed wiring assembly (PWA). The liquid may comprise an aqueous reducing agent solution for removing surface oxides prior to a soldering operation. The PWA is placed in proximity with the treatment solution held in a reservoir. Gas bubbles generated in the solution dynamically elevate and apply the solution to the bottom surface of the PWA. The bubbles may be formed by a non-oxidizing gas, such as nitrogen, introduced through a porous material. A flat surface of porous material produces a uniform bubble size that allows controlled and precise application of the solution. The porous material and the gas pressure may be varied to so that the bubbles elevate the solution to the desired level. The gas bubbles are short-lived (without surfactants) so that rapid transport, replenishment, and regeneration of the solution can be achieved. Moreover, nitrogen gas is injected at the PWA surface as the bubbles burst so that reaction of the solution or the PWA with oxygen is minimized. The gas bubble method also minimizes the pressure that forces treatment liquid through PWA through-holes to the top surface where it can be difficult to remove.

Title: Peristaltic pump tube cassette for blood processing systems and the like
Inventor: DENNEHEY T MICHAEL
IPC: A61M1/02
Filed: 1994-03-17
Abstract: A cassette (22A/B/C) serves in association with one or more peristaltic pumps to centralize pumping, valving, and pressure sensing functions. The cassette includes a housing (110) having first and second pump ports. A flexible tubing loop (134/136) extends between the first and second pump ports outside the housing for engagement with an external peristaltic pump element. A liquid port on the housing attaches to a length of tubing that also extends outside the housing. Liquid passages within the housing establish communication among the liquid port, the first pump port and the second pump port. Valve stations (Vn) formed within the housing are responsive to the application of external force for controlling liquid flow through the liquid passages. A sensing chamber (Sn) is formed within the housing along at least one liquid passage. The sensing chamber transmits information regarding liquid pressure present within the one liquid passage to an external sensing element.

Title: Method for planarization of submicron vias and the manufacture of semiconductor integrated circuits
Inventor: HENDEL RUDI
IPC: H01L21/321
Filed: 1994-03-25
Abstract: Submicron vias (12-14) are filled by sputter deposition of a conductor such as aluminum (15) onto a substrate (11) such as silicon or silicon oxides. The aluminum film (15) is deposited at a first lower temperature and then the temperature is increased. The differential coefficient of thermal expansion of the substrate (11) relative to the metal (15) conductor forces the conductor to expand into the via (12-14). Maintaining an effective thickness (1+) and controlling the temperature increase from the first temperature to the second temperature, effectively and reliably fills submicron vias having aspect ratios up to 4. The present invention is particularly useful with filling vias having re-entrant angles up to 20°.
