Abstract: A method for restoring integrated circuit devices in an encapsulated array of integrated circuit devices includes the steps of testing the array and applying a voltage signal to pins appearing to be disconnected from an element internal to the array.

Abstract: A connector backshell contains a wad of wire wool encapsulated in an elastomeric silicone. Screened cables extend through passages through the wad and have their braided screening sleeves exposed within the passages. The wire wool is exposed within the passages and on the outside of the wad so that it electrically connects the screening sleeves with the inside of the backshell.

Abstract: A connector for a bundle of screened wires has grounding wires connecting the housing with the screens of the wires. Each screen projects in a tubular portion of a respective metal connection device together with one end of a grounding wire. The tubular portion is crimped to a C-shape in section so that it lies closely against the wire. A support tail of concave section extends rearwardly from the tubular portion and is attached to the outside of the wire.

Abstract: An obturator for a tracheostomy tube has a strap extending along its length between a nose at its patient end and a machine end with clips that fasten to a coupling on the tube. The strap has one web extending along its entire length and a second web extending orthogonally on one side of the first web to form a T shape section along the major part of the strap towards its patient end. This makes the patient end of the strap relatively rigid whilst its machine end is relatively flexible to enable the machine end to be twisted to release the engagement of the clips and to enable the obturator to be pulled out of the tube.

Abstract: An electrical connector has a forward assembly with an outer metal housing supporting several insulative blocks containing the connector contacts. The rear end of each contact has a socket into which is inserted the forward end of conductors contained in a rear assembly. Some of the conductors are filtered and others unfiltered. Connection is made to the rear end of the conductors in the rear assembly by means of plates connected at the end of a cable, the plates supporting contacts that are a push-fit in the rear of the conductors in the rear assembly.

Abstract: An aircraft has several ultrasonic phased arrays acoustically bonded to parts of its structure to be monitored. The arrays are energized to produce an ultrasonic beam that scans the structure in two planes. A monitor receives the output from the arrays produced by reflection of energy from discontinuities within the structure. When there is a change in these outputs, the monitor signals a pilot display unit and a flight control system such that the aircraft flight envelope can be restricted to minimize damage.

Abstract: A tool, specifically adapted for inserting a lamp module in a lamp module receptacle and for removal of a lamp module from a receptacle, is provided with a longitudinally extending handle having opposite ends and a lamp removal head at one end of the handle for engaging the head of a lamp tether and disconnecting the tether head from a tether rail, and a lamp insertion head at an opposite end of the handle to facilitate engagement of a lamp tether head with a tether rail in a lamp receptacle.

Abstract: An indicator for detecting correct intubation of an endotracheal tube has a paper color-change element attached to a frame that is removably secured in a transparent connector in the machine end of the tube. A handle on the frame extends along the outside of the connector so that the indicator can be removed from the machine end of the connector by pulling the handle. The indicator prevents another connector being attached to the connector in the tube until after the indicator has been removed.

Abstract: A needle protector assembly for protecting a needle tip after it has been withdrawn from a catheter has a protective housing into which the needle is slid. A device at the patient end of the housing has two locking arms sprung outwardly away from one another, which engage projections on the hub of the catheter. A shutter plate and finger project inwardly from the locking arms and each has a catch that engages one another. The finger is sprung rearwardly away from the shutter plate but is held forwardly by a trigger lever engaging the side of the needle. When the needle is withdrawn into the housing, the trigger lever springs down allowing the finger to move rearwardly away from the shutter plate, thereby disengaging the catches. This allows the locking arms to spring outwardly and disengage the catheter hub, so that the assembly can be removed from the catheter.

Abstract: A flat panel lamp has internal walls forming a serpentine discharge path between two internal electrodes. Two glow mode electrodes in the form of interdigitated combs are laid on the outside of the front panel of the lamp, on top of the walls. The internal electrodes are connected to a first drive circuit; the glow mode electrodes are connected to a second drive circuit, which drives them at a frequency of about 10 MHz. At high brightness, only the internal electrodes are operative; at low brightness, only the glow mode electrodes are operative; and at intermediate brightness the two sets of electrodes are alternately energized.

Abstract: A radiating coaxial cable includes an inner conductor, an electrical insulator located about a periphery of the inner conductor, and an outer conductor located about a periphery of the electrical insulator. The outer conductor defines groups of apertures spaced from each other a predetermined distance in the range of from about twice the longest operational wavelength of the cable to less than ten meters. The aperture groups are designed in such a way to excite a surface wave at low operating frequencies and a combination of surface and radiating waves at high operational frequencies.

Abstract: A laryngeal mask assembly has an elliptical mask portion at the patient end of a tube. The mask portion has a mount attached to the tube and a cuff extending around the periphery of the mount. The patient end of the tube opens into the center of the mount, which has three lateral ribs projecting forwardly and extending parallel and spaced from one another. The forward end of the ribs have a concave profile with rounded projections at each end. The ribs act to hold the epiglottis away from the tube opening during insertion of the assembly and to provide an air passage into the tube.

Abstract: An hydraulic bath seat lift has a hydraulic cylinder assembly comprising an inner cylinder fixed with the floor and an outer cylinder, which can be raised and lowered by supplying hydraulic fluid to the assembly. The outer cylinder supports a seat at the end of a horizontal arm. The inner cylinder has a pin at its upper end projecting outwardly into one of two sets of longitudinal grooves along the inner surface of the outer cylinder to prevent the outer cylinder rotating relative to the inner cylinder. The grooves open into one another at the lower end of the outer cylinder so that when the outer cylinder is raised fully, to lift the seat above the bath, the cylinder can be rotated to swing the seat over the bath and then lowered with the pin engaging the other set of grooves.
