Abstract: Methods are disclosed for treating brain injuries and brain dysfunction with the administration of dextrose. The disclosed methods of treatment with dextrose can be used to treat brain injuries such as concussions, conditions related to prior brain injuries such as chronic traumatic encephalopathy, and brain dysfunctions which may be caused by genetic or environmental factors, such as multiple sclerosis or post-traumatic stress disorder. The disclosed methods provide for safe and effective treatment of brain injuries and brain dysfunction in a cost-effective manner with minimal adverse side-effects.

Abstract: Apparatus for drying media in a printer includes first and second successive printing stations with a first rotatable member that contacts the wet side of the media between them. Each prints on one side of the media. A media-path extender between the first printing station and the first rotatable member includes a dry-side rotatable member and a wet-side rotatable member around which the media path passes in that order. An extension media path is defined from the first printing station past the dry-side member, the wet-side member, and the first rotatable member, in that order, to the second printing station. The printer selectively transports the media either along a bypass media path or along the extension media path. The wet-side member is farther past the first printing station than is the first rotatable member.

Abstract: A digital printing system for printing on a continuous web of print media includes a first module and a second module that guide a continuous web of print media under tension through the printing system. At least one of the first module and the second module include a digital printhead for placing marks on the print media as it travels through the module. The first module includes a first support structure. A first mechanism is affixed to the first support structure and includes structure that positions the print media in a cross track direction. A second mechanism is affixed to the first support structure and includes structure that sets a tension of the print media. The second module includes a second support structure and is positioned downstream from the first module.

Abstract: A printhead includes a nozzle plate and a nozzle bore located in the nozzle plate. In one embodiment, the nozzle bore includes a first section, a second section, and a third section when viewed in a plane perpendicular to the nozzle plate. The first section and the second section are spaced apart from each other by the third section. The first section includes a converging area portion and the second section includes a diverging area portion. In another embodiment, the first section and the second section of the nozzle bore are adjacent to each other. The first section includes a converging area portion and the second section includes a diverging area portion. The diverging area portion and the converging area portion are asymmetrical relative to each other when viewed along the plane perpendicular to the nozzle plate.

Abstract: An improved drive circuit is provided for a DC motor. The drive circuit includes: a DC power source; a relay having a normally open contact and a normally closed contact; a DC motor electrically connected through the normally open contact of the relay to the power source; and a discharge circuit connected in parallel to the DC motor. More specifically, the discharge circuit is coupled to the normally closed contact of the relay and operable to inhibit current flow from the DC motor until the relay has settled in a closed position.

Abstract: A mounting apparatus holds in position a droplet generator assembly to be mounted in a continuous ink jet printing system. The droplet generator assembly comprises a pair of conical slots and a pair of conical apertures, located on opposing sides of the droplet generator. A resonator clamping plate includes a plurality of mating protrusions. A resonator support includes a plurality of spherical protrusions. A holding force, such as a screw, securely holds the assembled structure. The clamp and support interact with the conical slots and apertures to locate and exactly constrain the droplet generator. With the mounting structure of the present invention, the six degrees of freedom of adjustment are controlled.

Abstract: An apparatus and method allows for mounting and aligning of the charge plate/catcher assembly and the droplet generator within the structure that holds these two parts. Three degrees of freedom of adjustment are incorporated into the frame and are self-locking. Two of the degrees of freedom are the positioning distance of a jet array to charge leads and the parallelism of the jet array to the charge leads. The third degree of freedom is the ability to adjust the jet array so as to align and center the jets in front of the charge leads.

Abstract: An ink jet printer includes an ink jet printhead having a drop generator and an ink drop charging and catching assembly. An elastomeric seal mounted on a lever arm about a pivot remote from the charging and catching assembly seals the ink drop generator and charging and catching assembly when the ink jet printer is not in use.

Abstract: A catcher for an ink jet print head is provided with locating features in the catcher throat to positively locate a catcher screen that serves to wick caught ink into the catcher throat, and a screen construction that resists compression of the screen without adversely affecting the ink flow in the catcher throat.

Abstract: A stimulator for a continuous ink jet print head is fabricated by providing a surface roughness of between 100 and 200 microinches on the surface of the stimulator body and attaching a piezoelectric transducer strip to the body using an acrylic cement having a viscosity of between 2 and 100 centipois. The resulting stimulator exhibits improved lifetime with acceptable acoustic properties.

Abstract: A security system, particularly for a vehicle, comprises an electrical security key usable to make circuits which either directly, or through relays controlling other circuits, render operable electrical devices necessary for the starting of the engine of the vehicle by a conventional ignition key and switch. To confuse a person attempting to breach the security, conductors necessary to supply power to the devices are made discontinous within a wiring loom of the vehicle and other conductors are tapped-in at sides of the discontinuities and extend to relay contacts operable by the use of the key. Further to confuse such person, further conductors are connected to other relay contacts but have no operating function.

Abstract: A method for the production of bitumen from a subterranean reservoir having a zone of increased effective permeability therein. In particular, a first well is in fluid communication with the zone of increased effective permeability at a first level in the reservoir. Fluid communication is established between a second well and the zone of increased effective permeability at a second level above the first level in the reservoir. In-situ combustion is initiated in the reservoir proximate the second well. Combustion sustaining fluid is injected through the second well into the zone of increased effective permeability so that bitumens in the reservoir are mobilized by the in-situ combustion and flow downward through the reservoir towards the first well, through which they are recovered.

Abstract: A sheet stacking apparatus for receiving sheets from a printing or copying machine includes guide structure for directing output sheets onto an elevator platform and a selectively rotatable shaft having paddle arms disposed at a 108.degree. interval. The shaft rotation is controlled so that the arms guide a sheet during stacker input and then rotates 360.degree. to positively clear the sheet trail edge from the stacker input path.

Abstract: A method for conditioning the virgin drainage area of a tar sand formation that is penetrated by a well for enhanced petroleum production by cyclic steam stimulation is described. The method comprises fracturing the drainage area by injection of liquid carbon dioxide. While carbon dioxide is still in place within the formation, steam is injected into the formation. After a suitable soaking period, the well is opened to production. This method achieves better petroleum recovery than conventional huff-puff steam stimulation techniques.
