Abstract: A piston-powered fluid-dispensing system (20) is disclosed. The fluid dispensing system (20) comprises an apertured base (22), a hollow elongated cylinder (24A), an apertured piston (26), an orificed overcap (28A), an elongated fluid passageway (30A), and three valves (34, 36A, 38A). The elongated cylinder (24A) defines a longitudinal axis (x-x). The elongated cylinder (24A) carries the base (22) at one end portion thereof and further defining a hollow neck at the opposite end portion thereof. The apertured piston (26) defines a circumferential portion (44) that is slidably engageable with the hollow cylinder (24A) substantially along the length of an inner surface thereof, and the piston (26) is disposed in the cylinder (24A) for dividing the cylinder into at least two chambers (46A, 48A). The orificed overcap (28A) is carried by the cylinder (24A) and is rotatable about the longitudinal axis, relative to the cylinder (24A). The overcap (28A) defines a throat (62A) that is slidably en­gageable with an inner surface portion of the cyl­inder neck (42A). Rotation of either the overcap (28A) or cyl­inder (24A) relative to the other, about the longitudinal axis, provides movement of the throat (62A) relative to the cylinder neck (42A) along the longitudinal axis. The throat (62A) carries means for providing fluid communica­tion between one of the two cylinder chambers (46A, 40A) and a fluid-mixing region. The fluid passageway (30A) is carried by the overcap (28A) and is disposed through the piston aperture in a fluid-tight manner. A first valve (34) is carried by the base. A second valve (36A) is carried by the fluid passageway (30A) and abuttingly engages the first valve (34). The third valve (38A) is provided by movement along the longitudinal axis of the throat relative to the cylinder neck.

Abstract: A liquid regulator device has a buoyant body which is anchored to a side of the vessel by an electrical conductor. The body contains a movable ballast in the form of a ball and an attitude sensitive switch connected to the electrical conductor. The buoyant body floats in the liquid with one end in the uppermost position. Changing the liquid level tensions the electrical conductor causing the body to tumble. When the body has tumbled through a predetermined angle, the ballast moves from one end of the body to the other to cause the body to rapidly assume the reverse orientation. This causes the attitude sensitive switch to change state, which is used to control the liquid level.

Abstract: An analog associative processor for discriminating between intersects representing targets and intersects repre­senting ghosts from angle-only information from multiple sensors. The analog associative processor is constructed using a multi-layer substrate that is an analogue of the real-world sensor emplacements, angular sensor traces, and coordinate system. A method is implemented by the analog associative processor which detects ghosts by counting (20, 22) pulses received by each intersect from the other intersects. When the number of pulses reaching a given intersect reaches a predetermined threshold (T3), the intersect is identified as a ghost. The analog associative processor then continues (26) until the number of remaining intersects equals the number (N) of total targets. The remaining intersects are then identi­fied (28) as true targets. The analog associative processor is faster than conventional software solutions to deghosting problems and contains few components so that it is inexpensive to manufacture (Fig. 3).

Abstract: A vehicle guidance system includes a computer (5) for generating signals to control a number of vehicles (2,3) to carry out movements within a predetermined area (4). Data identifying locations of notional points (16-22; a-d) on the floor of the area are entered into the computer together with a look-up table specifying pairs of those points between which movements of vehicles may be required, and specifying which other of the movements between pairs of points must be considered as potential causes of collision between vehicles when any particular movement is to be effected. When a vehicle movement is requested, the computer determines from the table which other movements must be considered, and determines whether any such movements are being effected at that instant. If so, the computer inhibits the requested vehicle movement or, if not, it initiates the requested vehicle movement.

IPC: C09J103/02
Filed: 1990-02-23
Abstract: The invention is a method of controlling the final viscosity of a starch glue at a constant starch content and an apparatus for carrying out the method. The invention concerns a process for preparing a starch glue in which part or all of the starch in the glue is partially swollen to a predetermined "critical" swelling viscosity when the swelling process is terminated and the "final" viscosity is only reached after a subsequent period of agitation. The method of the invention reduces the critical swelling viscosity during the process as the elapsed reaction time increases thereby ensuring a constant final viscosity at a constant starch content of the glue.

Abstract: There is disclosed a system and method for generating coefficients for use in a digital filter. The coefficients are generated utilizing an iterative adaptive process employing a least mean square process wherein the filter coefficients are updated by an amount during each iteration dependant upon the stochastic average of the gradients generated during prior iterations. The response of a filter standard to an applied input signal is combined with a response of the adaptive filter coefficients to generate, during each iteration, an error signal. If the error signal is less than a predetermined standard, the iterative process is stopped, and the last used filter coefficients are utilized as the final filter coefficients of the digital filter.
