Title: Multi inlet air flow passage arrangement for diesel engines
IPC: F02B75/02
Filed: 1979-01-31
Abstract: An inlet air passage (14) introduces air into a cylinder bore (12) of a diesel engine (10) in a direction along a flow path substantially tangent to the cylinder bore to provide a swirling of the air within the bore. A second inlet air passage (14) introduces air into the same cylinder bore in a direction along a flow path toward the centerline of the cylinder bore axis which minimizes swirl within the cylinder bore. The non-swirling air flow path is utilized during start up and cold idle and the swirling air flow path is individually used when the engine operates through its intermediate speed range with both air flow paths being simultaneously directed into the cylinder bore during high speed operation of the engine for optimum volumetric efficiency.

Title: Method of manufacturing electrical cartridge fuselinks and fuselinks manufactured by the method
IPC: H01H85/041
Filed: 1980-12-03
Abstract: A fuse element (15) for an electrical cartridge fuse comprises a fusible wire (2) secured to opposite end zones (3) of an insulating strip (1) by metallic layers (4) sprayed on to the end zones. The insulating strip has a slot therein between the end zones to prevent the fusible, central section of the wire from contacting the strip. The fuse element is disposed in an insulating barrel (16) and the layers (4) are soldered to end caps (17) of the barrel to connect the fusible wire thereto. Fuse elements of this construction are produced by disposing a fusible wire along a continuous strip of insulating material formed at equally spaced intervals with slots and spraying the metallic layers onto the strip between the slots so as to adhere the fusible wire to the strip. Thereafter, the strip is severed at the zones between the slots so as to produce individual fuse elements. This method of manufacture facilitates the production of cartridge fuses utilizing small diameter fusiblewires. <IMAGE>

Title: Commutated doppler radar system
IPC: G01S13/50
Filed: 1982-04-22
Abstract: This invention is a commutated Doppler radar system for detecting or tracking distant targets. It is a three- dimensional system which provides information about target range R, elevation h and bearing theta , by transmitting two signals (Fc + Fo) and (Fc - Fo) from a ground transmitter Tx via transmitting elements 2, 3. The double sideband signal reflected by a distant target 5 is received by a "mobile" receiver Rx (commutation) and contains Doppler shifts due to target and receiver motions. It provides a difference frequency component for determining the elevation and velocity of the target and a sum frequency component for detecting and correcting errors. A feature of the system is its use of four well-known techniques for reducing errors in the system which are frequency diversity, space diversity, time diversity and a large time- bandwidth products. A combination of all four techniques is used to obtain a better overall system performance. <IMAGE>
