Title: Method and apparatus for inspection of substrates
Inventor: AMIR ISRAEL
IPC: G01N21/93
Filed: 1990-01-23
Granted: 1994-04-19
Abstract: Abstract Inspection of a circuit board to detect missing and misaligned active and passive surface-mounted components and, respectively, is accomplished by first illuminating the board with top light to enhance the image of the passive components. The circuit board is then displaced, relative to a linescan camera trained on the board, so that the camera captures the image of successive strips of surface area running across the board perpendicular to its direction of movement. The images captured by the camera are stored and thereafter processed by an image-processing system to determine whether any passive component is missing or misaligned. The circuit board is then illuminated with side light to enhance the image of the active components. The circuit board is again displaced relative to the linescan camera so the camera captures the image of successive strips of surface area on the board. The captured images are stored and then processed by the image-processing system to detect whether any of the active surface-mounted components are missing or misaligned.

Abstract: ABSTRACT OF THE DISCLOSURE          In the continuous production of mineral wool fleeces, fibre-/ gas-/ air- mixtures (3,4), which are produced by several defibration units (14 to 17), are directed onto collector conveyor units (19, 21) with curved suction surfaces, which are under suction pressure (c, d), for the formation of a wool fleece (25).  Here the arrangement is done in such a way, that each fibre-/ gas-/ air- mixture, which is formed by the individual defibration units (14 to 17), is assigned to an imaginary suction surface, which increases in size in the direction of the movement of the conveyor, namely d > c.  It is thereby possible, under constant suction pressure to produce mineral wool fleeces of good production quality from rock wools with gross densities of even less than 25 kg/m3 per collector conveyor unit in a space saving construction method.  Furthermore, composite webs of felt can be formed by several units connected in series or by way of a pendular deposit of a single fleece.

Abstract: A mechanical  seat  suspension  inside  a  housing  comprises parallel scissor arms and a support arm with a cam connected to suspension springs.  The support arm, which carries the substantial majority of the seat load, has a height adjustment means and a cam with two arcuate surfaces that define an imaginary pivot point.          The use of the cam with the imaginary pivot point permits a more compact structure.  Various embodiments of the support arm with a cam end and devices using the support arm are also disclosed.  A shock absorber attached to the outside of the scissor arms dampens the stroke of the suspension springs connected to the cam.  The ratio of the shock stroke travel to the vertical movement of the seat remains generally linear and constant, thus producing a more comfortable ride.  Also included is a height adjustment mechanism on the support arm that interlocks with the cam by a pivoting pawl and biasing spring.  The height of the seat is adjusted by the relative movement of the top portion of the housing to the lower portion.  No external levers, triggers, or other structures are necessary for seat adjustment.   The tension in the suspension springs is adjustable to compensate for the weight of the rider.          Another embodiment of the suspension includes a support assembly with two support arms that move relative to a cam that can be latched in five positions.  Compression springs connected to the support assembly and disengaging arms with a disengaging roller permit a power assisted height adjustment.

Title: Automation of telephone operator assistance calls
Inventor: DOWDEN DOUGLAS C
IPC: H04M3/42
Filed: 1991-08-30
Granted: 1995-03-14
Abstract: This invention relates to methods and apparatus for automatically processing operator assistance calls. A caller is connected to an automated operator position. The automated position has speech recognition facilities to replace those of an operator, has announcement capabilities to replace those of an operator, and has control means for transmitting and receiving the same set of messages transmitted and received by an operator position. Advantageously, the operator assistance switch has the same interface to an automated position as to an operator position and interacts with the two identically. Since the capabilities of the automated position are limited by its program, the automated position switches a call to an automated position when a situation occurs for which it has not been programmed. Advantageously, a switch need not be specially programmed to communicate with an automated position. Advantageously, new operator assistance services can be provided automatically without rewriting the complex control software of the switch. The invention further relates to the use of automated operator positions for providing spontaneous voice message service wherein a caller converts a call to a message call if the called party does not answer or is busy, and to a method of recognizing a voice specified destination and establishing a call to that destination.

Inventor: DILLON LARRY STEPHEN
IPC: F04B47/02
Filed: 1992-03-02
Granted: 1996-12-24
Abstract: A manual pumping apparatus for the delivery of water from a deep well to the ground surface. The pumping apparatus consists of a surface mounted drive unit, a handpump lever operated handle, a sub-surface pump unit, and a water filled flexible riser pipe connecting the drive and pump units. The pumping operation is commenced by the downward movement of the handpump lever handle which forces a drive unit piston disc downward by means of connecting linkage rod. Water is forced down the flexible riser pipe below the piston disc closing a check valve on the upper end of a hollow pump rod to increase water pressure and hydraulically force the pump rod to slide downward and compress a helical coil spring located at the base of the pump unit. Leather seals on the piston discs and one way check valves at each end of the hollow pump rod prevent water leakage between pump components and maintain the driving force due to the increasing water pressure in the handpump system. As the increased water pressure compresses the helical coil spring and forces the lower piston disc downward, a check valve opens and permits water to enter an expanding volume of space, or storage chamber, between two pump unit reservoir cylinders of different diameters. The upward movement of the handpump lever handle releases the water pressure allowing the compressed helical coil spring to expand which forces the storage chamber water up the riser pipe to the drive unit reservoir cylinder and out the discharge nozzle. The deep well handpump is designed to be simple to operate, inexpensive to manufacture with readily available parts, easy to maintain and repair, and capable of extended periods of reliable operation. The use of a flexible connecting riser pipe between the drive and pump units for energy transfer and water flow is a significant improvement over the common method using of a metal connecting rod which is subject to mechanical breakdown. The deep well handpump will be useful in rural areas of under-developed countries where simplicity and reliability are important, and where maintenance can best be done by local labour with few tools using simple components.
