Assignee:

Honeywell International Inc. - Morristown NJ

International Classification:

H04M 1104

US Classification:

Abstract:

A controller area network (CAN) has a plurality of nodes connected to transmit and receive data over a serial data line. An AC power source is also connected to each node. Each node senses the AC power waveform and synchronizes bit transmission and bit detection with the waveform. In a preferred embodiment, each node includes a circuit that detects zero crossings by the AC waveform, providing two accurately synchronized bit intervals per complete AC cycle. A preferred version of the invention includes hardware and software that detects miswires of the node to the data and power lines.

Abstract:

A sorbent filter for use with an air-purifying apparatus. The filter includes a flexible bag and a sorbent material in granular form. The flexible bag defines at least one storage region and is formed of a porous material. The sorbent material is disposed within the storage region. With this configuration, the porosity of the flexible bag is configured to allow passage of air such that the air, including air-borne gaseous molecules or odors, can interact with and be adsorbed by the sorbent material. Conversely, however, the porosity of the flexible bag limits passage of sorbent material granules and dust. As such, the filter generates little if any dust during handling. In one preferred embodiment, the flexible bag is selectively attachable to a separate frame that in turn is designed for mounting within the air-purifying apparatus. With this configuration, the frame can be re-used such that filter replacement requires only a new sorbent filter.

International Classification:

US Classification:

83 621, 83554, 83 767, 836392

Abstract:

A press for forming a workpiece with a tooling set includes an actuator assembly carrying a movable half or punch of the tooling set and having a two phase operation. In the first phase the actuator provides relatively low force in moving the punch to an intermediate position in close proximity to the workpiece. A sensor detects the position of the punch, and when the punch reaches the intermediate position provides a continue signal. The second phase of actuator operation is conditioned on occurrence of the continue signal, and uses normal high force to press the movable tooling half against the workpiece to complete the operation. The low force first phase allows obstructions of any kind to stop movement of the punch during the first phase before high force applied to the actuator may cause damage or injury to the obstruction. In a preferred embodiment the actuator assembly has hydraulic operation.

International Classification:

US Classification:

439502, 439218, 439507, 439638

Abstract:

A connector cable assembly has first and second plugs wired to permit plugging into a first pair of electrical plugs with a pair of terminals in a first configuration to place the terminals of those plugs in parallel connection, and to permit plugging into a second pair of electrical plugs with a pair of terminals in a second configuration, to place the terminals of those plugs in series connection. In a commercial embodiment, such a cable assembly can be used to provide power to electrical devices such as gas valves connected to receive power in parallel from the first pair of electrical plugs, and to connect in series, safety switches connected to plugs with a pair of terminals in the second configuration. By using an adapter with specialized connections between two sets of terminals it is possible to use additional cable assemblies to connect in excess of two switches in series.

US Classification:

141 90, 141 85, 141 89, 141 91, 222148

Abstract:

A liquid-dispensing nozzle has a system for blowing air for a period of time through the nozzle's spout after the liquid valve closes. The flow of air purges and expels most of the liquid adhering to the interior surface of the spout, preventing this residual liquid from contaminating either the ground on which it may fall when the spout is withdrawn from a filler pipe or the air through evaporation. The invention applies particularly well to dispensing of liquid fuels such as gasoline.

International Classification:

US Classification:

33 211, 33 321, 33 323

Abstract:

A tool for scribing a longitudinal groove on an elongate cylindrical rod suitable for implanting as a prosthetic in a living being supports the rod in a linear groove on a bed of a frame of the tool. A track is mounted on the frame and runs parallel to the groove. A carrier mounted on the track can slide on the track in constant spaced relation to and along the groove. A scribe mounted on the carrier extends toward the groove to contact a rod in the predetermined position. A preferred version of the tool has a clamp mounted on the bed for clamping the rod in the predetermined position. Additional features allow for precise angular positioning of the rod and for scribing a dashed line on the rod. In use, the tool operator places the rod in the predetermined position in the groove. The scribe is then pressed into contact with the rod.
