Title: A method of operating a seismic air gun array
Inventor: SAFAR MO HUSSAIN
IPC: G01V1/02
Filed: 1987-04-15
Abstract: A compact airgun sub-array is formed by a number of airguns having different or the same chamber sizes. The airguns are spaced so that there is sufficient interaction between the airguns when fired simultaneously. The presence of interaction between the airguns makes it possible to generate a desired pressure pulse using fewer airguns. The characteristic of the pressure pulse is further improved by firing the airgun sub-array several times with some airguns being switched off. The period of the combined pressure pulse is different from that of the individual pressure pulses and the combined bubble pulse is more strongly damped.

Title: An artificial intelligent system for human error prevention in automated machine systems
Inventor: NJEMANZE PHILIP CHIDI
IPC: A61B5/16
Filed: 1989-04-26
Abstract: In an intelligent machine system which exerts a level of decision-making autonomy appropriate to circumstances of automated machinery and robotics, realtime assessment of a machine - operator's workload during active interaction with the automated system is carried out noninvasively. Using 2MHz Doppler probes, the mean blood flow velocities in both middle cerebral arteries are measured. The percentage change of mean flow velocity in both hemispheres is used to estimate operator's workload and performance. If this exceeds his/her normal thresholds, then the decision-making as regards production process is passed onto another operator or the automated machine. This will ensure a better man-machine interface needed for safety and efficiency in establishments requiring high- precision performance. <IMAGE>

Title: Method of redrawing a metal cap
Inventor: KOBAYASHI TOMOMI
IPC: B21D22/20
Filed: 1990-11-13
Abstract: The method comprises using an annular working member 4 in conjunction with a redrawing die 2 a redrawing punch 1 and a cup-shaped holding member 3, the working face 4A of the annular working member having a diameter smaller than the outer diameter of a preliminarily drawn cup to be redrawn. The diameter of the cup being thus reduced immediately before redrawing by relative movement between the punch 1 and the die 2, whilst a holding force is applied to the blank between the face 3A of member 3 and face 2A of die 2, promotes uniform reduction in thickness of the drawn cup without damage to the metal or a coating layer. The method can be used in reverse re-drawing (Fig. 4). <IMAGE>

Title: Twist action mop
Inventor: MCKAY P
IPC: A47L13/142
Filed: 1990-11-26
Abstract: A twist action mop comprises a handle 16 and a string-type mop head 15 connected at one end to the lower end of the handle and at its other end to a tube 17 mounted on the handle is provided with a mechanism for twisting the mop head about the lower end of the handle by a pulling and rotary action on the tube. Guide pins 19 co-operate with a track 18 on the handle 16. At a pull of a handle 23 the tube travels straight up until the mop head 15 is under tension in line with the handle, the load on a spring 26 being just enough to support the water laden mop head. A further pull of the handle 23 creates at least one full rotation of the tube 17 and a final wringing out process is achieved by rotating the tube by a lever 24. Instead of a handle 23 to lift the tube 17, an electric motor with rechargeable batteries may be employed driving a rack-and-pinion mechanism. <IMAGE>

Title: Moving picture/false window
Inventor: SOLIMAN SAYED MOUHAMMED
IPC: G09F19/12
Filed: 1991-04-08
Abstract: The 'MOVING PICTURE/FALSE WINDOW' is a line of home furnishing which features picture images on canvas stretches and carried by separate sets of rollers moved by gears which are driven by an electrically operated motor within a frame optionally encased by special magnifying glass. Separate parts of scenery are printed on separate stretches of canvas and fixed on the separate sets of rollers for different directions of movement. An example scene is 'SHIP ON OCEAN' where the ship. clouds and birds at the top half of the picture are printed on a first canvas stretch and move horizontally. The ocean waves with floating objects are on a second stretch and move vertically. The special magnifying glass that encases the scenery has increased thickness at the bottom half to create an illusion of depth and closeness such as ocean waves appearing to become bigger and closer as they approach. Each set of rollers, which creates one direction of movement, may have different diameters to overlap the canvas and not show the line of separation in movement. In another embodiment (Figure 10, not shown) a transparent stretch of material carrying piscatorial images is moved by a set of rollers in front of a sheet of material carrying other images so as to create the illusion of an aquarium. <IMAGE>
