  • Patent number: 5327473
    Abstract: A timing circuit 10 that can be used to control the flow of fluid according to a specific time period that is allotted for each user includes a initialization circuit 30, a reset counter circuit 32, a flow time counter circuit 38, and a clock circuit 40. The timing circuit 10 accepts a DETECT* input signal, that indicates the presence of a user, and provides a DRIVE output signal that indicates when fluid shall be permitted to flow. The flow time counter circuit 38 is user configurable to provide a maximum flow time period while the DETECT* signal is active. The reset counter circuit 32 ensures that each user is provided with his or her maximum flow time period by introducing a system reset time between consecutive users and by allowing a user to remove him or her self from being detected, thus placing the DETECT* signal in an inactive state and subsequently inactivating the DRIVE signal, for certain periods of time without forfeiting any of his or her allotted maximum flow time period.

  • Patent number: 5170514
    Abstract: A system for controlling liquid flow in bathrooms and the like in response to the presence of the user, which is configuration-adjustable to permit use in preselected sanitary applications. Light emitting means cooperate with a light sensor to detect light reflected from the user. The filtered and amplified output signal from the sensor is demodulated to provide a DC output signal. First circuit means responsive to the DC output signal actuate fluid flow for a maximum preselected period, to enable use in controlling faucet flow. Second circuit means responsive to the DC signal include means for arming the circuit following the existence of the DC output signal for a first predetermined period; and means for thereupon generating a flow control signal for a second predetermined period following extinction of the DC output signal to enable use of the system to control flushing of urinals or commodes.

  • Patent number: 4823414
    Abstract: An automatically controlled faucet-sink system having a fluid dispensing faucet with a sink disposed below that faucet, is controlled by means of a light source-photosensor pair juxtapositioned within a housing mounted on or near the back of the sink so that the light beam and cone of vision of the photosensor are focused at a point intersecting the path of fluid flow from the faucet. Electrical circuitry and valve apparatus are provided which actuate and then cut-off the flow of fluid from the faucet in response to an object under the faucet reflecting light from the light source to the photosensor. Circuitry is also provided for terminating the flow of fluid from the faucet to the sink after a predetermined period has timed out.

  • Patent number: 4638412
    Abstract: A method and apparatus built into and for illuminating the interior of a pocketbook, includes a photodetector circuit sensitive to low levels of ambient light for turning on a switching circuit to energize a light bulb mounted within the pocketbook, and a relay mechanism responsive to closure of the pocketbook for preventing operation of the photodetector circuit for turning on the switching circuit.

  • Patent number: 4556803
    Abstract: An electrically powered hand tool, such as a staple gun, can employ an electrical driver, such as a solenoid, which is actuated by a trigger circuit in response to depression of a trigger on the handle of the device. The trigger circuit can include a circuit board dimensioned to fit into the handle of the staple gun, and having AC input leads. A circuit formed of conventional electronic components delivers a burst of power to output leads which are in turn connected to a driver solenoid. This circuit is actuated to deliver the power burst by opening of a switch formed of two switch members: one switch member has a first flexible resilient conductive leaf formed, e.g., of an alloy of copper, extending beyond an edge of the board; the other member has a flexible resilient leaf with a bent-in pointed end contacting a side of the first blade. These blades are biased against each other to form a normally-closed switch. When the first blade is moved in one direction, the switch opens.

  • Patent number: 4489546
    Abstract: A friction false-twisting unit has three upstanding parallel shafts supported on a base plate. Each shaft carries a plurality of friction disks and the disks are overlapping and interleaved for applying a false twist to filament yarn drawn through the array of disks where they overlap. To damp the oscillation of the entire false twisting unit, it is fastened to the machine bed through interposed damping elements. There is a holding mandrel on the base plate which passes through a guide sleeve. The guide sleeve is, in turn, attached to the mount via the damping elements. With the false-twisting unit absent, the damping elements tilt the guide sleeve and when the unit is in place, its weight in use returns the guide sleeve to a correct orientation, so that the plane of the side of the drive whorl on one of the shafts is parallel to the plane of the tangential drive belt for that shaft where that belt passes the drive whorl.

  • Patent number: 4353642
    Abstract: A microfilm cartridge storage, retrieval, and projection system is disclosed. The system includes a vertically-oriented cylindrical cartridge storage drum which has a plurality of overlying tiers, each tier including successive side-by-side compartments which are oriented along radials of the cylinder and are adapted to hold a microfilm cartridge. Cartridge receiving and projection head means are mounted proximate the compartments of the drum, and are adapted for receiving a cartridge from a compartment in operative opposition thereto and for optically projecting a selected film frame of the cartridge. Cartridge displacement means mounted proximate the compartments of the drum, are adapted for displacing a cartridge in operative opposition thereto, which is then engaged by the receiving and projection head means. Orienting means are provided to enable relative vertical displacement between the drum, and each of the cartridge receiving and projection head means and the cartridge displacement means.

  • Patent number: 3937927
    Abstract: Frame location system for microfilm retrieval system. Frame address of desired frame is stored in first reversible counter having maximum count greater than the maximum possible number of frames in a roll of microfilm. Frame address of frame currently being viewed is stored in second reversible counter of same count capacity. A burst of pulses equal to capacity of both counters causes both to count up. First counter to overflow gates burst pulses into third reversible counter. Second counter to overflow terminates count in third counter. As microfilm moves, optical sensors sense frame identifying "blips" on microfilm thereby reducing count in third counter and slowing film to halt when desired frame is in position at viewing station.

  • Patent number: 3934241
    Abstract: Analog display utilizing liquid crystal material and for being multiplexed wherein the segments (one group of electrodes) are arranged in groups opposite sectors (the counter electrodes) and wherein the segments in each group are disposed in a sequence opposite to the sequence in which the segments of the next adjacent group are disposed and, further, wherein a segment in each group corresponds to a segment in each other group and wherein all corresponding segments are electrically interconnected in a series connection. In timed sequence with the input signals applied to the sectors, input signals are applied to the segments in a first predetermined sequence with regard to a direction of display movement to be provided by the display, and alternately, the input signals are applied to the segments in an opposite sequence with regard to the direction of display movement whereby the display movement is in one continuous direction.
