Publication number: 20210276004Abstract: A pipettor includes a wash chamber between an upper plate, a lower plate, an upper seal, and a lower seal. The upper and lower seal retain each other and are located between the upper and lower plates. The pipettor includes a gasket located below the lower plate, a pipette tip retained by the gasket, and a piston with a tapered tip that passes through the plates, seals, and gasket into the pipette tip. The upper and lower seal isolate the piston from the wash chamber. The pipettor includes a channel defined by the piston, extending into the pipette tip, and an actuator that advances and retracts the piston.Type: ApplicationFiled: May 24, 2021Publication date: September 9, 2021Inventors: Richard J.

The upper and lower seal isolate the piston from the wash chamber. The pipettor includes a channel defined by the piston, extending into the pipette tip, and an actuator that advances and retracts the piston. When the actuator retracts the piston such that the piston loses sealing contact with the lower seal and the wash chamber is supplied with wash fluid and pressurized, wash fluid passes through the groove in the upper seal and into the channel.Type: GrantFiled: July 29, 2016Date of Patent: June 29, 2021Assignee: Douglas Scientific, LLCInventors: Richard J.

Patent number: 9921101Abstract: A scanning photometer and attendant methods are provided. The scanning photometer is generally characterized by first and second fluorophore excitation sources, an objective lens, and a common emission detector for the detection of first and second fluorophore emission originating from the excitation of the fluorophores via passage of excitation energy, via an optical path of the objective lens, from the excitation sources. Excitation energy and emission energy conditioning elements are likewise provided, operatively interposed before or after the objective lens as the case may be.Type: GrantFiled: June 19, 2014Date of Patent: March 20, 2018Assignee: DOUGLAS SCIENTIFIC, LLCInventors: Adnanul Haq, Richard J.

Patent number: 5543699Abstract: A device (10) is disclosed including a discharge unit (54) having a vertical conveyor (56) formed by a pair of vertically arranged belts (58) each including circumferentially spaced shelves (60) defining a plurality of evenly spaced flights. A diverting conveyor (16) is pivotally mounted about its infeed end so that its outfeed end can be moved to be synchronous with one of the flights of the discharge unit (54) or to an overflow position. In particular, a servo motor (50) pivots the diverting conveyor (16) under the control of a controller (74) depending upon whether product is detected by a sensor (52) in the diverting conveyor (16), upon the rate that the flights of the discharge unit (54) are moving, and upon the pivotal position of the diverting conveyor (16). The device (10) is then able to place products which are fed to the diverting conveyor (16) with random spacing into the flights without bumping or bunching the products together.Type: GrantFiled: May 27, 1994Date of Patent: August 6, 1996Assignee: Douglas Machine Limited Liability CompanyInventor: Richard J.

Patent number: 5444750Abstract: Apparatus for counting and selectively voiding tickets. An input bin is provided wherein a stack of tickets are initially queued. Using a conveyor, each ticket is advanced from the input bin past a sensing device. The sensing device detects the presence of each ticket and produces a signal indicative of the passage of each ticket past the sensing device. This signal is conveyed to an electronic counting device that maintains a cumulative total count of the tickets. The apparatus may be set to continuously count any tickets placed in the input bin or set to stop after counting a predetermined number of tickets. The apparatus also includes a punch that is selectively controlled to enable the optional voiding of each ticket as it is counted.Type: GrantFiled: November 9, 1993Date of Patent: August 22, 1995Assignee: Bass Gambling Supplies Inc.Inventors: William L. Stewart, Leonard A. Miller, Thomas H. Peterman, Marlo G. Schoeneck, Richard J. Schoeneck
