An integrated rectifier assembly having a coil of wire wound to form a solenoid about a thermoplastic bobbin. The coil of wire has a pair of leads for coupling to an external electrical circuit. A rectifier device is connected to the pair of leads of the solenoid coil to rectify power delivered to the coil. The rectifier device is a silicon rectifier and has two pairs of bifurcated legs which are soldered or otherwise electrically coupled to the electrical socket prongs normally associated with ...

A method for ventilation within a room, in which a duct is provided in the ceiling of a closed room and another duct is provided under the floor thereof, both passing horizontally through the building, having openings in the same direction and connected with the room by an air supply and an air exhaust pipe, wherein air is supplied through the duct provided under the floor and is exhausted by way of the duct provided in the ceiling.

The invention concerns a method and apparatus for detecting Doppler-shifted waveforms in electrical signals. A replica is derived from the waveform prior to Doppler shift and stored in a storage device as a non-uniform profile having progressively increasing distortion along its length. The replica storage device is connected non-uniformly to correlating means such that the correlated replica profile has a degree of uniform distortion varying with storage position simulating varying degrees of D...

A preheater is disclosed which can be inserted and withdrawn from a well tube defining a curved passage, without having its heating element damaged, by utilizing the flexibility of a spirally coiled structure having increased stability of shape and excellent capacity of restoring its original shape after elastic deformation.

A container for packaging fragile items. The container provides an inner carton suspended within an outer carton. The suspension is achieved by means of integral end flaps on the inner carton which interlock the end flaps of the outer carton.

A low impedance crossunder region is formed of a low resistivity emitter diffusion within a base region of an active device which extends beneath a portion of a metallization pattern to be crossed. The low resistivity crossunder diffusion is shorted to the base region in order to prevent transistor action between the crossunder region and the base region in contrast with other emitter diffusions within the base region which form diode junctions with the base region.

A vessel for the long term storage and monitoring of nuclear fuel materials incorporates a device (12) within its interior for providing an externally detectable signal indicating whether any pressure loss has occurred. The device (12) comprises a magnet (32) attracted towards a boundary wall (11) of the vessel and urged in that direction by the internal pressure within the vessel acting on a diaphragm (26). The magnet (32) is subjected to oppositely directed forces by pressurized fluid in chamb...

A vessel for the storage and monitoring of nuclear fuel materials incorporates a device (12) within its interior for providing an externally detectable signal indicating whether any temperature rise has occurred. The device (12) comprises a magnet (32) attracted towards a boundary wall (11) of the vessel and maintained in that position by a temperature-sensitive element such as a thermal link (38). The magnet (32) is subjected to an oppositely directed force by a spring (30), which is effective ...

A device for tapping within die comprising a power guide means, a transmission means and a tapping means in which the power guide means can transmit power from horizontal displacement of a rack via a gear train in the transmission means to drive a rotating spiral gear to rotate and consequently cause a tapping unit in the tapping means to rotate and displace axially upon action of a guide spiral sleeve and a resistance element, and to tap by overcoming frictional resistance of the resistance ele...

A method and apparatus for cooling elements generating heat within a vacuum and the center of a large mass of hot material including a heat pipe having the input end within a vacuum or a large mass of material and the output end exterior thereof, and means for subjecting the output end to an electrostatic field to materially increase the rate of heat transfer into the atmosphere.
