Abstract: A composite seal comprising a primary seal element and a secondary sealing element. The primary seal element is more readily deformable than the secondary seal element. Juxtaposed surfaces of the seal elements are configured to minimize extrusion of the primary seal element past the secondary seal element.

Abstract: A tool for applying a spring clamp comrising a pair of handles, a pin joining said handles for relative rotation, a pair of jaws on said handles, a cam carried by one of the jaws and a pair of side plates pivotally supported by the other of said jaws having cam control tracks therein for effecting and controlling radial movement of said cam to complete closure of said clamp.

Abstract: The present invention discloses a device for detecting the presence of an intruder listening device on a telephone or data line. The device comprises an electrical circuit electrically connected to the telephone line for measuring the values, polarity and electrical characteristics of the telephone line. These measured values are then compared with predetermined values for each electrical characteristic which are stored by the electrical circuit. An indicator is activated by the electrical circuit when the measured value varies from its respective predetermined value by more than a predetermined amount. The circuit, which is preferably microprocessor controlled, also includes a signal sweep generator for generating one or more electrical wave forms into the telephone line as well as a receiver which receives and analyzes the reflected signal from the telephone line.

Abstract: An electrical connector is disclosed which is of the kind comprising a male tab insertable in a female clip. The female clip (3) has the general form of a hollow parallelepiped the bottom wall (5,6) of which comprises an elastically deformable tab portion (5) (9) engageable in an opening of corresponding male tab portion.

Abstract: A socket for the reception of a bulb comprising a housing having a grommet receptacle therein for the acceptance of a grommet in sealing relationship. An electrically conductive wire extends through the grommet for connection to an internal terminal strip of the housing. An integral latch on the housing biases the grommet into its receptacle in the housing and secures the grommet in position therein.

Abstract: A tool for applying and removing a spring clamp comprising a pair of handles, a pin joining the handles for relative rotation and a pair of jaws on the handles. One of the jaws is relatively thin in radial dimension relative to the axis of rotation thereof and the other of the jaws is relatively thick in radial dimension relative to the axis of rotation thereof whereby said tool is reversible to effect closure and opening of the spring clamp.

Abstract: A construction of a gas turbine combustion chamber which facilitates relighting the fuel immediately after flame-out. The construction comprises a catalytic coating on the combustor wall, preferably with areas left uncoated to allow the flame to propagate away from the combustor wall and into the bulk gas flow.

Abstract: A bolt is provided with a male thread, an end portion of which is of modified configuration, for acceptance in an element having a female thread of standard configuration. The modified portion of the male thread has a wedge ramp at the root thereof and a decreased pitch relative to the standard pitch of the thread on the female element which, in combination, results in optimum distribution of stress in the bolt as well as a prevailing torque relationship between the bolt and female element.

Abstract: A medium bypass turbofan engine including a fan mounted on a low pressure shaft and positioned at the inlet of the engine; an intermediate pressure single-stage axial compressor carried by the low pressure shaft and positioned to receive a working airstream portion of the air discharged by the fan; a single-stage high pressure centrifugal compressor positioned to receive the output of the intermediate pressure compressor and carried by a high pressure shaft received telescopically over the low pressure shaft; an annular burner positioned to receive the output of the high pressure compressor; an annular slinger carried by the low pressure shaft and arranged to inject fuel into the burner; a high pressure single-stage axial turbine positioned to receive the output of the burner and carried by the high pressure shaft; and a low pressure multi-stage axial turbine positioned to receive the output of the high pressure turbine and carried by the low pressure shaft.

Abstract: An oxygen starting assist system for a gas turbine engine which facilitates lighting or relighting the air-fuel of the engine comprising a tubular element surrounding the spark plug that directs pure oxygen to the tip of the spark plug so as to envelop an arc drawn by the spark plug without passing through the arc.

Abstract: The disclosure relates to a system for the co-generation of steam and electricity from a gaseous fuel. A Brayton cycle turbine drives first and second fuel and air compressors as well as an electric generator. Steam is also produced by the system for direct utilization or to drive a steam turbine which also drives the generator.

Abstract: A fastener comprising a nut with V-threads modified to have a wedge ramp between adjacent flanks at the root thereof and characterized by the uniform pitch of the nut thread being a predetermined amount greater than the uniform pitch of the bolt thread which, in combination with the wedge ramp, results in optimum stress distribution within the bolt as well as a prevailing torque and anti-vibration relationship between the nut and bolt.

Abstract: The disclosure relates to a process for the fabrication of low cost dual property turbine rotors having blades that are diffusion bonded to a blade ring that is simultaneously diffusion bonded to a central hub.
