Abstract: Disclosed is a light weight handle assembly adapted to transport a heavy duty container which may contain sensitive electronic components. The handle assembly of the present invention generally comprises a stationary bracket which mounts to a container wall and a movable handle pivotally connected to the bracket. The bracket is formed with an inner portion that is adapted to rotatably engage with a pair of pivoting arms extending from the movable handle so that the light weight handle may easily be assembled and disassembled. Each of the pivoting arms is formed with a movable stop member which is advantageously positioned to contact and bear against stationary stop members which are attached to or are a part of the container to which the handle is attached.

Abstract: A latch is disclosed incorporating features allowing complete actuation i.e., engagement and disengagement of a latching hook on the side of the container from a latch handle on the face of the container thus allowing actuation of the latch hook even when the latch hook is itself inaccessible. The latch also features variability in the stroke of the hook and a design allowing its construction from plastic material.

Abstract: A device for guiding alignment in trailer hitching with a trailer cup attachment and a towing vehicle attachment. The trailer cup attachment adjustably clips over the trailer cup on the drawbar of the trailer. The trailer cup attachment has at least one vertical rod and an alignment indicator equipped with guide lights and a sound generator to indicate when the ball on the towing vehicle is in hitching position relative to the trailer cup. The towing vehicle attachment has a mounting base for removable temporary mounting on the towing vehicle. Telescoping rods are rotatably mounted in the mounting base. At the end of the telescoping rods is a fluorescent colored activating ball which is positioned directly above the tow ball on the towing vehicle. The alignment guide and activating ball are positioned to be visible to the operator of the towing vehicle through a rear view mirror, rear window, or the like.

Abstract: This invention relates to an electronic rack and mounting frame for protecting sensitive electronic equipment against damage caused by impacts and excessive vibration during shipping and handling.

Abstract: An injection molded panel composed of two half-panels each comprising a skin having matching integral webs or ribs disposed perpendicular to said skin wherein said half-panels are bonded together along said webs or ribs.

Abstract: Disclosed are hair conditioning shampoo compositions comprisingA liquid hair conditioning shampoo composition comprising:(a) from about 5% to about 50%, by weight, of an anionic surfactant component;(b) from about 0.1% to about 10%, by weight, of a dispersed, insoluble, nonvolatile, nonionic silicone hair conditioning agent;(c) from about 0.05% to about 10%, by weight, of soluble, organic, polymeric cationic hair conditioning agent, said polymeric, cationic hair conditioning agent consisting essentially of one or more cationic, hair conditioning polymers, said cationic hair conditioning polymers having quaternary ammonium or cationic amino moieties, or a mixture thereof, an open chain backbone, and a charge density of about +3.0 meq/gram or less; andThe shampoo compositions hereof can provide excellent overall hair conditioning benefits, in conjunction with excellent cleaning performance, to a variety of hair types including treated hair such as permed and color-treated hair, as well as undamaged hair.

Abstract: The present invention relates to rinse off hair conditioner compositions comprising from about 0.2% to about 20% of certain hair styling polymers, from about 0.2% to about 20% of certain non-aqueous solvents for said hair styling polymers, and from about 0.05% to about 25% of a hair conditioning agent, in an aqueous base, wherein the polymer and solvent are present in the composition as a dispersed fluid phase.

Abstract: The present invention relates to hair shampoo compositions comprising from about 5% to about 30% of a surfactant, from about 0.2% to about 20% of certain hair styling polymers, and from about 0.2% to about 20% of a solvent for said hair styling polymer. These compositions provide hair cleaning and styling benefits from a single product. Preferred compositions of the present invention additionally comprise from about 0.01% to about 10% of a silicone hair conditioning agent. These compositions provide hair conditioning, cleaning and styling benefits from a single product.

Abstract: The present invention relates to hair styling compositions comprising from about 0.2% to about 20% of certain hair styling polymers, from about 0.2% to about 20% of certain non-aqueous solvents for said hair styling polymers, and the balance, an aqueous base; wherein the hair styling polymer and the solvent therefor are dispersed as a separate fluid phase in the aqueous base of the hair styling composition.

Abstract: A fetal heart rate monitor monitors weak fetal electrocardiogram signals in the presence of strong interfering material ECG complexes, general random background muscle noise, and 60 Hz power line noise. An electrocardiographic adaptive cancellation process to cancel the maternal ECG component from an abdominal ECG signal recorded from a pregnant subject's abdomen signal is processed using computer software. A set of easily movable maternal abdominal and thoracic ECG electrodes is used. An operator views the ECG data in an oscilloscope and optimally places the set of thoracic electrodes to adaptively cancel the maternal ECG signal from the signal separately derived from a movable abdominal electrocardiographic lead. The invention noninvasively obtains from the abdomen of a pregnant subject the fetal ECG signal, fetal heart rate, and accurate beat-to-beat fetal heart rate variability.

Abstract: In the particular embodiment of a device for removing dissolved gas from ink described in the specification, an elongated ink path leading to an ink jet head is formed between two permeable fluorine-containing membranes. The membranes are backed by air plenums which contain support members to hold the membranes in position. Reduced pressure is applied to the plenums to extract dissolved gas from the ink in the ink path without accumulating scum on the membrane surfaces. Increased pressure can also be applied to the plenums to eject ink from the ink jet head for purging. Within the ink jet head, ink is circulated convectively from the orifice to the deaerating path even when the jet is not jetting ink.
