Assignee:

Delaware Capital Formation, Inc. - Wilmington DE

International Classification:

H02G015/02

US Classification:

174 74R, 174 77

Abstract:

Embodiments of the present invention are directed to forming a seal around cables passing through an opening of a sealed enclosure in an efficient and cost-effective manner. In one embodiment, a cable sealing apparatus has a body including a plurality of grooves and a hinge. The body is foldable around the hinge to form a plurality of cable apertures from pairs of the grooves in a folded position. The body has a resilient material to form a seal around each cable disposed in a corresponding cable aperture upon being compressed by a force moving the body to the folded position. In another embodiment, a cable sealing apparatus has a body including a plurality of cable apertures each having a length. The body has a plurality of longitudinal slits each extending along the length of one of the cable apertures and disposed between the cable aperture and an external surface of the body. Each longitudinal slit is configured to be openable to receive a cable from the external surface of the body through the longitudinal slit into the cable aperture.

Abstract:

A method and system for switching the dispensing of a first solution from a first vessel to dispensing a second solution from a second vessel when a parameter of the first solution crosses a threshold is described. In one embodiment, a fluid dispensing apparatus includes a first vessel and a second vessel. The first vessel includes an output conduit adapted to dispense the first solution from the first vessel into a fluid receiving region. The second vessel includes an output conduit adapted to dispense the second solution from the second vessel into the fluid receiving region. The apparatus includes a first sensor positioned to measure a parameter of the first solution before the first fluid enters the fluid receiving region. The apparatus also includes a second sensor positioned to measure a parameter of the second solution before the second solution enters the fluid receiving region.

Appl. No.:

11/404711

Inventors:

David Howland - Aptos CA, US
David Stadille - Salinas CA, US

Assignee:

Delaware Capital Formation, Inc. - Wilmington DE

International Classification:

G01F 1/22

US Classification:

073861570

Abstract:

An apparatus, for use with a fluid moving device that moves a fluid from a container. The apparatus includes a flowtube having a passage, the flowtube having a first end and a second end. A body is positioned in the passage of the flowtube, and a sensor array comprising at least two sensors is positioned along the length of the flowtube and between the first end and second end of the flowtube. The sensors in the sensor array sense (e.g., detect) the body as the body flows past the sensors. The sensors in the sensor array are adapted to generate signals, and a controller is operatively coupled to the sensor array. The controller is adapted to control the fluid moving device in response to the signals generated by the sensor array.

Assignee:

Delaware Capital Formation, Inc. - Wilmington DE

International Classification:

G02B 500
G06K 710

US Classification:

23546232

Abstract:

A marked card reader having a lensless optical detection system with fixed angle illumination and detection, the sensitivity of which is independent of the frequency response associated therewith. The optical detection system includes a radiation source to produce radiation and a radiation detector. A target plane is positioned so that the radiation source directs radiation toward the target plane. The detection source is positioned to sense radiation reflected from the target plane. An optically opaque body is positioned between the optical detector and the radiation source to prevent incident radiation from be sensed by the optical detector.

International Classification:

A47L 1544

US Classification:

307118

Abstract:

Improved timing circuits (205), charge dispensing circuits (213,215), and methods and systems (100) for operation of warewashing equipment. According to one aspect of the invention the system operates on both door and conveyor types of machines. The system dispenses both an initial charge amount and a dose amount during normal operations. In door types of systems, only a single power/signal connection (109) needs to be made to the dispensing system; in one embodiment the warewash rinse power connection. Further, the system can dispense detergent at an interval of greater than once per cycle or operation.
