Title: Detecting faults on a printed circuit board
Inventor: CHANDLER KEVIN G
IPC: G01R31/3183
Filed: 1994-08-31
Granted: 1997-04-16
Abstract: An automatic circuit board tester for testing for shorts, opens, and interconnected pins or nodes on a circuit board. The tester first classifies the nodes as being in one of three categories based upon the design of the board and the intended interconnection of the nodes. The categories of nodes are: (1) connected to ground; (2) interconnected to all other nodes in the test group; or (3) isolated from all other nodes. The circuit board tester has a testhead containing a plurality of test channels, each configured to be coupled to a node on the circuit board. The testhead utilizes a digital signal from a digital driver to drive the node at a predetermined voltage and a digital receiver to read the node voltage to determine if it is coupled to ground. Each test channel also includes a switch to connect the digital driver and receiver to the test node as well as a ground switch to selectively couple the node to ground. Various combinations of switch positions and testing sequences enables the circuit board tester to test all node connections and to ensure that the physical embodiment of the circuit board accurately reflects the circuit board design.

Title: Method of producing a composite structure
Inventor: BANSEMIR HORST
IPC: H01L41/313
Filed: 1998-07-17
Granted: 2001-09-12
Abstract: A composite structure (3) includes a piezoelectric element (1) sandwiched between fiber composite panels (2). The composite structure can be used as an actuator element. In a method for producing the composite structure, the fiber composite panels are pre-stressed and pre-strained by applying respective pre-stressing forces (F1, F2) in opposite directions along two substantially perpendicular axes in the plane of the panel. The pre-stressed and pre-strained condition of the fiber composite panels (2) is maintained, while the panels are adhesively bonded (5) surfacially onto the piezoelectric element (1). After the bonding is completed, the pre-stressing forces are removed from the fiber composite panels. As a result, in the finished composite structure (3), the fiber composite panels (2) are under internal tension, while the piezoelectric element (1) is under internal compression. The pre-stressing forces (F1, F2) are particularly selected in magnitude and direction to achieve the required resultant balance of tension and compression within the composite structure (3). The pre-compression of the piezoelectric element (1) should be sufficient so that operating loads on the composite structure do not result in tension loading of the piezoceramic element, while substantially maintaining the useful active strain range of the overall composite structure.

Title: Slurry mixer for buoyant particle slurries - has finger baffles which remain in vicinity of the slurry liq. level
IPC: B01F/
Filed: 1979-01-30
Granted: 1985-12-23
Abstract: The mixer comprises a tank having a turbine agitator blade near the bottom and a number of finger baffles, e.g. of triangular or rectangular shape for continuously assisting mixing located adjacent the tank wall. Throughout mixing the baffles remain in the vicinity of the slurry liq. level. In constant level agitated tanks they are secured to the tank wall. In variable level tanks they are mounted on floats. Used for processing synthesised polymer particles in the mfr. of elastomers. Accumulation of buoyant stagnant particles on the liq. surface is prevented and a uniform outlet slurry concn. is obtd. The finger baffles, as opposed to full baffles extending the full length of the tank, result in efficient mixing at lower turbine agitator blade speeds.

Title: Method of machining of materials
Inventor: SHATUROV GENNADY FILIPPOVICH
IPC: B23B/
Filed: 1985-06-06
Granted: 1987-10-28
Abstract: The machining method consists in main and feed movements imparted to the work and/or a round-edge tool. The edge is turned angularly around an axis normal to the edge plane to always present a non-worn edge sector. The angular turns of the cutter should only be in one direction up to half the edge (4)/work (1) contact angle (PSI). The time it takes a given point on the cutting edge to pass through the contact angle should be long enough to ensure uniform wear. The angular tool movement should be achieved by moving points on the cutting edge (4) through the cutting zone in the feed direction (S) during cutting, pref. when the cross-sectional area of the layer removed from the work is below its max. value. The time (Tan) a given point on the edge (4) remains in work from the start of one turn to the start of the next, and the turn value should be varied during cutting such that TAU PSI/PHI Z = const. Tau is the cycle time for each point on the cutting edge, PSI being the contact angle between the edge and work and PHI, the angle through which the cutter is turned round an axis normal to the edge plane. Z is the frequency, the cutting edge passes through the cutting zone.

The phosphors may be removably located in recesses (4,5) on opposite sides of a plate (1) having an opaque openable cover (2,3) on each side to hold the phosphors in place. The base (13) of the recesses acts as a further part of the filter for radiation to the eye phosphor, and the cover over the skin phosphor includes a hole covered by a thin opaque sheet (12) to filter radiation. The covers are pref. hinged to opposite edges of the plate, and the plate, hinges and covers are formed as an integral assembly from opaque plastics, e.g. carbon-filled polypropylene.

Title: Partially multi-tubular fabric-walled container particularly for hand baggage
Inventor: TERZAGHI GIOVANNI
IPC: B65D/
Filed: 1983-06-03
Granted: 1987-04-08
Abstract: Using this invention, it is possible to produce containers intended particularly for hand baggage, at least partially made of double-walled fabric in contiguous tube form made of retractile synthetic fabric with or without reticulated dressing. This gives a greater surface area which is harder-wearing (not being subject to the usual risks of scratching) and has higher shock absorbance because of the elasticity of the multi-tubular area. It is hard wearing because of its elasticity and stands up to knocks. The outer layers can be multicoloured or can carry any type of design. Furthermore, manufacture in tube form automatically creates a surface that is also resistant to damp, oxidisation and to any accidental spills of acidic or alkaline liquids. The internal facing of the double layer can be a finishing layer, as it is completely waterproof and stands up to light alkalis like the most common detergents. When a lining is desired it can be applied using all the usual techniques and also by glueing or heat sealing.<IMAGE>

Title: Thermal polishing of glass
Inventor: EREMEEV VADIM VASILIEVICH
IPC: C03B/
Filed: 1981-05-08
Granted: 1986-09-03
Abstract: Thermal polishing of glass articles to form a sculptured pattern is effected using a flow of heat concentrated into a beam passing successively over the whole surface of the article, the breadth of the zone of action of the heat flow being chosen to be less than the perimeter of the article and so that the thermal stress on each element of the sculptured design is constant. The technique may be used in mfr. of Pb crystal glass, lighting glassware, (lamps, lustre elements etc.) and other glass manufactures requiring an improvement of the surface. The method is simplified and the quality of polishing inproved by choosing the shape of the heating flow to match the pattern to be sculpted. The working conditions are improved by comparison with those of prior art acid polishing techniques. Thermal polishing improves prod. quality by avoiding fusion of sharp corners or edges when these are required, and removing them when they are not. The process can be automated.
