A rotor assembly for rotary vacuum pumps has improved mechanical characteristics and low manufacturing cost due to a one-step thermal coupling of a rotor having a male axial projection and its supporting shaft having an end portion comprising a female cavity with a shape and size for receiving the male projection with interference at an ambient temperature. The rotor and the shaft are made of different materials. Heating of the end portion of the shaft provides expansion of the female cavity and allows for inserting the mail projection of the rotor into the female cavity of the shaft. By cooling the end portion to the ambient temperature the contraction of the cavity is obtained forming fixed interference coupling between the shaft and the rotor, where the end portion of the shaft contracts and compresses about the male axis projection of the rotor.

The third magnetic layer has an anisotropic magnetic field smaller than the anisotropic magnetic field of the second magnetic layer, and has a saturation magnetization greater than the saturation magnetization of the second magnetic layer.

The invention is a device for removable placement in the mouth, which advances the lower jaw and draws the tongue forward and upward, thereby providing relief for snoring and obstructive sleep apnea. The device includes an upper portion, the upper surface of which is adapted for engagement with the user's upper dentition. A downward extension, suspended from the anterior part of the upper portion, features an anterior surface that engages the back of the lower front teeth, so as to advance the lower jaw forward with respect to the upper jaw. The posterior surface of the downward extension features a rearward extension, which is curved upward at its lateral margins to meet the upper portion, so as to define, with the hard palate of the user, a cavity that is sized and shaped to snugly engage the user's tongue. Within the defined cavity, the device preferably features a soft elastomeric surface.

Energy conversion devices employing gases and / or liquids as medium, constructed with a hollow, preferably toroidal cylinder having two ports and two, or more, identical ferromagnetic pistons moveably sealing the hollow cylinder. Movements of the pistons are electromagnetically selectable from the outside of the cylinder to either impart varying unidirectional forces on the medium and / or to influence a magnetic circuit placed outside the cylinder for the generation of motive or electromotive forces. In a pump, a compressor and an externally heated engine, the selective movement of the pistons always maintains a piston between the two ports. In an internal-combustion engine, addition is made of more pistons and one piston is selectively stopped and approached by the adjacent piston, compressing a gaseous mixture to effect combustion; electronic detection of the combustion allows the rapid electromagnetic release of the stopped piston and stops the adjacent piston which was compressing prior to the combustion.

The fuel cell (2) is of the kind comprising an anode (12) and a cathode (10) between which an electrolyte (18) is interposed. Solid bodies (20) storing a hydrogen mass, able to be decomposed by combustion, are associated to pyrotechnic means (24,26) to release the hydrogen and bring it into contact with the anode (12). Means (38) tap the ambient air to bring it into contact with the cathode (10). Firing of the pyrotechnic means (24,26) is placed under the control of addressing means (28) embedded in the appliance (2). The surplus water produced by the exchange between the hydrogen and the oxygen is resorbed by the temperature increase induced by combustion of the bodies (20). The solid bodies (20) are supported by an interchangeable card (22).

An ink pad holder for use with a self-inking reciprocating hand stamp. The ink pad holder has an upper and lower compartment, with an ink pad mounted in each compartment. The ink pad holder can be inserted in the hand stamp with either ink pad facing the printing plate so that different inks can be applied to the printing plate. This allows the user greater versatility such as using the ink pad for finger printing applications by impregnating one of the ink pads with finger printing ink. Alternatively only the lower compartment may have an ink pad mounted therein with the upper compartment remaining empty for storing small items. The ink pad holder is easily removed from the hand stamp so the ink pads are easily accessible for re-inking.

A reversible food and game tray device for use with a child safety seat includes a two-sided tray that is easily reversible between two sides. One side includes a generally flat surface on which books, toys, games, and the like may be rested for use by a child. An opposed side defines multiple recesses for holding plates, cups, napkins, food, and drink items. The tray includes coupling elements for holding the tray in place as well as for enabling the tray to be quickly and easily reversed between the game and food surfaces. The coupling elements include at least one pin cooperatively positioned for releasably engaging a track. Preferably, two pairs of pins are provided along with a control lever for selectively retracting a selected pair of pins. Operation of the lever enables the tray to be pivoted, slid, and thus reversed.

A method and apparatus for adjusting the location of suspension for a tailgate is disclosed. The method may include selecting a vehicle comprising a first side, a second side, a tailgate, and at least one tailgate support. The tailgate may be connected to pivot with respect to the first and second sides through a range of motion. The at least one tailgate support may have a first end connected to the first side, a second end connected to tailgate, and an adjustor positioned between the first and second ends. The method may further include actuating or manipulating the adjustor to change the length under tension of at least one tailgate support. By changing this length, the location of suspension for the tailgate may be adjusted.

The present invention provides a gutter screen attachment and a ridged filter assembly for minimizing water film runoff and debris collection adjacent a screened gutter. The screen attachment comprises a superior breaker edge, an inferior breaker edge, and a screen-receiving region. The superior breaker edge extends upwardly opposite the inferior breaker edge and is designed to break the water tension of a water film formed upon the gutter screen. The ridged filter assembly comprises a filter support grid, a filter screen and a ridge-forming member sandwiched between the filter support grid and the filter screen. The filter screen is form fit to the underlying structures and the ridge-forming member thus forms a water tension straining ridge upon the filter screen. The superior breaker edge and the filter screen ridge function to allow water to permeate through the gutter screen.

A remote actuation system for de-manning a human / machine interface emulates the interface protocol to interact with the interface at a mechanical level. The system may function autonomously or with a remote human operator. At least one imaging module and at least one switch module with the same relative positions as and a complementary relief to the interface's gauge(s) and mechanical switch(es) are mounted on the instrument panel. The modules may be individually mounted or provided on a remote actuation panel that fits over the instrument panel. A data cable connects the imaging and switch modules to a processing module having at least one computer processor configured to execute an image-processing sub-module and a switch sub-module to emulate the protocol to interact with the interface at a mechanical level. The estimate of the measured value may be fed back to generate the switch command to control the remote switch actuator.

The present invention provides a gutter screen attachment for minimizing water film runoff and debris collection adjacent a screened gutter. The screen attachment comprises a superior breaker edge, an inferior breaker edge, and a screen-receiving region. The screen-receiving region comprises an edge-receiving fold that accepts the gutter-engaging edge of a gutter screen. The superior breaker edge extends upwardly opposite the inferior breaker edge and is designed to break the water tension of a water film formed upon the gutter screen. The inferior breaker edge is designed to prevent water leakage between the screen attachment and the gutter. The superior breaker edge is of minimized height so as to allow bulky debris to translate over the superior breaker edge. It is thus contemplated that the superior breaker edge functions to allow water to more properly permeate through the gutter screen.
