The forward and reverse rotation mechanism of the present invention has a drive source rotatable in one direction, a first spring clutch for moving a forwardly and reversely moving member in a forward direction, a second spring clutch for moving the forwardly and reversely moving member in a reverse direction, a first lever for actuating the first spring clutch, a second lever for actuating the second spring clutch, and a solenoid for actuating one of the first and second levers. The lever actua...

The system first incorporates an encoder which utilizes a 1/2 rate convolutional encoder to encode the data and a supplementary coding system for converting the 1/2 rate coded data to a nominal 3/4 rate. Thereafter, in order that the encoded data fits within the fixed frame length which has been adopted as a standard for the present TDMA transmission system, a portion of the excess data in each frame of encoded data put out by the encoder must be deleted or punched out. These bits are spaced thr...

A light of standard color is illuminated when the braking means of a vehicle is applied. The light is extinguished when the braking means are released. The light is located on the forepart of a vehicle preferably in the mid-line, facing in a forward direction the light beam emanating therefrom projecting towards the front of a vehicle, and is so placed at or above dash-board level so as to be clearly visible to other vehicles or persons facing said vehicle or through the rear view mirror if such...

In a forward looking radar in which from flying or stationary carriers land or marine surfaces in a forward lying sector region are imaged two-dimensionally, an antenna mounted rigidly on a carrier is made up of a plurality of individual elements preferably in the form of horn antennas arranged rectilinearly adjacent each other and in two rows above each other in such a manner that for a predetermined aperture length l of each individual element and for a predetermined spacing of the individual ...

A gas turbine engine fan blade includes a main body having a radially spaced apart root and tip, and axially spaced apart leading and trailing edges. A front shell is fixedly joined to a portion of the body leading edge to collectively define with the body an airfoil having first and second opposite sides extending between the root, tip, shell, and trailing edge for pressurizing air flowing thereover. The shell is hollow to offset toward the trailing edge a collective center of gravity of the ai...

A system and method for transferring video programs from a first location to a remote location provides for communication of the programs over selected commercial telephone networks. The program signals are digitized, compressed, and stored at the first location, and transferred to the remote location on request of a viewer. Due to the compression of the program, the time required for electronically transferring the program to the remote location is much less than the viewing time for such progr...

A rotor blade includes a root, tip, leading edge, trailing edge, forward surface, and aft surface, and a pitch section disposed equidistantly between the root and tip. The blade has a forward sweep from at least the pitch section to the blade tip relative to incoming streamsurfaces of a fluid flowable over the blade.

The compensation range of feed-forward amplifiers is expanded. The peak value of the input or output of an auxiliary amplifier 15 is detected with a peak power measuring instrument 24, and the characteristic of a distortion detecting loop 100 is controlled with a vector adjuster 3 and a control circuit 9 so as to minimize this peak value. By controlling the characteristic of the distortion detecting loop by detecting the peak value, the range of linearity compensation is expanded compared with c...

A method for forward projecting data from an image volume to a projection plane is described. In one embodiment, the method includes the steps of rotating the image data by a transaxial angle .phi. to align the image data with the projection plane. Then, for every axial angle .crclbar., and for each y'.sub.0 and for each value v in the projection plane: (a) determining z'.sub.0 =(v-y'.sub.0 sin .crclbar.)/ cos.crclbar. and interpolating in the z' direction for each x', to form the line I(x', y'....
