    摘要: A wedge shaped, inflatable cushion is provided having its body portion divided into ribbed sections defined by transverse ribs. The cushion body portion is quilted transversely to form the ribs and ribbed sections, the sections thus being in communication with each other so that pressure due to weight of a heavy portion of the body on one section urges forward, with the rib as a pivot point, the head and other sections which support lighter portions of the body, to hold the head in a virtually upright position.

    摘要: A retrievable seal guide (RSG) for installing a seal stem in a polished bore receptacle. The RSG has an outer grapple. Inside the grapple is a mandrel. At the end of the RSG is a bullet nose guide. The mandrel is spring loaded with a spring placed under the grapple Near the rear end of the guide is a plug with an o-ring. Note that the bullet nose has an opening formed in it. A channel is also formed down the length of the device. Note too that for tight formations of non-perforated liners the plug can be replaced with a stainless-steel ball that acts as a check valve. As the RSG is pulled out, the guide is pulled back, which compresses the spring forcing the mandrel back until a cam clears the collapsible fingers on the grapple, which allows the RSG to be withdrawn.

    摘要: A new blade for a shaver is disclosed with a profile where a single sided of the blade, rather than a dual sided blade, is ground to make a cutting surface. Such a single sided blade, or “chisel blade” has been found to have important advantages in scrubbing razors in particular, but in general for replaceable razor cartridges, whether used in scrubbing razor configuration or single cartridge applications.

    摘要: One embodiment of a securable and verifiable food delivery bag with a key component that is a panel (13) built seamlessly into the upper end (12). This element includes a pull strip (14) and an adhesive band (15) which allows the unit to be self-sealed. This panel (13) includes a Quick Response (QR) code (16) which may be utilized in a variety of capacities depending on factors such as the market, space and industry. Additionally incorporated is an identification number (17) which corresponds with QR code (16).

    摘要: A replaceable gas lift valve system. In this system, the device is inserted into the production tubing (or gas producing zone) at a desired level. This allows gas to be pumped down the space between the casing and production tubing (or flowed from the zone). Although the tool is placed in the production tubing, space is provided to allow almost normal production through the tool. Once in place, the device has a metering valve that allows the appropriate amount of gas of other fluid to enter the production tubing to provide lift for the oil. If the device fails, it can be quickly extracted and a replacement device quickly installed. Once installed, the replacement device allows resumed production. The recovered device can be dismantled, repaired and staged for another quick replacement where needed.

    摘要: An RF shielded room (14) which houses a magnetic resonance scanner (12) also houses a patient monitor (20) which includes a plurality of sensors (18) which collect physiological data about a patient undergoing a magnetic resonance examination. The monitor includes a transmitter (46) which transmits the physiological data on at least two frequency channels of a broadband frequency spectrum. A communication unit (26) located outside the RF shielded room includes first and second receivers (54, 58) which receive the physiological data from the monitor on the first and second frequency channels, respectively. A processor (62) combines physiological data received by the first and second receivers to. A display (32) displays the combined physiological data. A switch (56) switches antenna connections of the receivers (54, 58) responsive to detection of multipath fade.
