Abstract: The cylindrical enclosure for the gauge mechanism includes a front portion with a transparent surface and a rearwardly extending side wall which terminates at an outwardly extending flange. One or more gaskets of appropriate aggregate thickness are selected and situated on the flange. The front portion fits snuggly into the panel opening with the gaskets adjacent the rear surface of the panel. The gaskets are selected such that the thickness of the panel plus the aggregate thickness of the gaskets equals the depth of the side wall. This results in the front surface of the gauge being coplanar with the front surface of the panel. In this manner, a single size gauge enclosure can be adapted to be flush mounted to panels having a range of different thicknesses.

Abstract: The housing is mounted on and sealed around an opening in the pouch wall. The disc-like base of the housing has a central, axially extending entrance passageway aligned with the pouch opening. A portion of the base extends radially outwardly beyond the seal and has a second axial passageway therethrough. The cover of the housing defines a filter receiving recess aligned with the entrance passageway. The recess has a connecting channel extending radially therefrom. The cover is removably mounted on the base for relative rotational movement between a first position in which the connecting channel aligns with the exit passageway, so as to permit venting of the gases from the pouch, and a second position wherein the connecting channel is out of alignment with the exit passageway, closing the vent.

Abstract: A member in the form of an overfilm or molded housing affixed to the pouch wall has a plurality of isolated vent passages. A separate filter assembly is situated in each of the passages. Adhesive coated covers are situated to obstruct the flow through all but a selected one of the passages. After the filter in the unobstructed passage has lost its effectiveness, the cover is removed from another passage and placed over the passage containing the used filter to obstruct same. The filter in each passage is used, in turn, by appropriate movement of the cover, until all of the filters have been used.

Abstract: A feedback coder, which employs simple CMOS push/pull amplifiers as gain elements, along with a bistable circuit, in its preferred embodiment takes the form of a second-order delta-sigma modulator. The output of the modulator is converted into pulse code modulated words by a finite impluse response filter which incorporates a partial coefficient generator utilizing simplified logic. The generator output is provided to an accumulator in which the stage operate at reduced speed. A simple multiplexer generates a serial output. The entire converter can be integrated on a semiconductor chip of relatively small area.

Abstract: A wafer with a <100> orientation comprises N layer (middle layer) and a lightly doped P layer (top layer). A strongly doped N layer (source layer) is diffused into most of the top layer. An oxide layer is grown. A V groove with a flat bottom is anisotropically etched through openings in the oxide layer. The V groove is etched through the source layer and most of the P layer. The bottom of the groove initially is at a level above the junction between the top layer and the middle layer. Exposure to beam of phosphorus ions forms a shallow implanted channel region proximate the walls of the groove. An unwanted implanted region along the bottom of the groove is also formed. A second anisotropic etch, through the same oxide mask, deepens the groove bottom to a point below the junction, removing the unwanted portion of the implanted region along the groove bottom. The implanted concentration of the channel is later reduced as the gate oxide is formed.

Abstract: A mechanical and electrical bond between a silicon semiconductor wafer and a molybdenum contact is created by a multi-layer brazing material. The material includes adjacent layers of titanium and silver along with a layer which is either composed of aluminum or an aluminum-silicon composite. The material is heated to a temperature above its melting point. The aluminum reacts first with the silver, thereby dissolving less of the silicon. This reduces spiking and lowers the contact resistance.

Abstract: A first cylindrically shaped part surrounds and is fixed to the needle base which is mounted on the forward end of the syringe body. A second cylindrical part is mounted within the first part for axial movement between a forward position where the needle is surrounded for protection of the needle prior to mounting and between injections and a position in which the needle is exposed during an injection. A spring urges the second part towards the forward position. Locking elements are provided for permanently locking the second part in a third, axially spaced position to protect the needle after it has been discarded. Prior to and between injections, the second part may be non-permanently locked in the forward position by rotating it relative to the first part.

Abstract: Means are provided for monitoring water flow to a dwelling or the like and shutting off the flow if it exists for an abnormal period of time, the system being readily adjustable to adapt itself to different considerations of abnormality depending upon time of day, time of year, presence or absence of occupants in the dwelling, and the like.

Abstract: In order to effectively seal the space between a preexisting pipe and a repair lining that has been inserted into the pipe and radially expanded in order to generally conform to the interior of the pipe, a form is inserted between the ends of the pipe and lining before the lining is radially expanded, the lining therefore conforms to the interior of the pipe along its length and to the interior of the form at its ends, the form is removed, a sealing ring is inserted into the space left by the form and is there sealingly compressed, and an element is inserted into that space axially outside the sealing ring in order to retain it in position and preferably to compress it axially of the pipe.

Abstract: A layer of plastic, either in film or coating form, is bonded to a sheet of non-woven material to form a base. When film is used, it is preferably smaller in size than the non-woven material and affixed to the top surface thereof by an acrylic adhesive. The plastic film is coated, on its exposed surface, with a layer of acrylic adhesive. When the plastic is in the form of a coating, it is bonded to the bottom surface of the non-woven material. A superabsorbent pad, smaller in size than the base, is wrapped in non-woven material and affixed to the base by the exposed adhesive layer. The remaining portion of the exposed adhesive layer forms a border around the superabsorbent pad for adhering the bandage to the skin.

Abstract: Pouch faceplate connecting rings have adhesive annular base layers with cover layers. Each cover layer has an annular portion covering the base layer and a radially extending gripping portion with a radially extending edge and a circumferentially extending tapering edge. The gripping portions are annularly offset to facilitate removal of the cover layers.

Abstract: Automatic tag attaching apparatus having a fixedly mounted attacher with a hollow fastener dispensing needle is improved. A hollow, size adjustable anvil is adapted to be received between a woven label and the garment to which it is affixed, to keep the label taut and separate it from the garment. In one preferred embodiment, the anvil is moved downwardly over the needle upon which tags have been previously placed, such that the needle penetrates the label and a fastener can be dispensed. The anvil is then moved upwardly, to a position remote from the needle, to permit the tagged garment to be removed and new tags placed over the needle. In the most preferred embodiment, after the anvil returns to its position remote from the needle, it is moved horizontally to remove it from the garment. Thereafter, the anvil is moved back into alignment with the needle to receive the next garment.
