Abstract: CONTROLLED-DISCHARGE DOOR FOR PARTICULATE MATERIALS AND LIQUIDS                             Abstract A controlled-discharge door assembly for particulate material or liquids includes a door member (30) with a curved surface engaged by a large diameter roller (46) mounted to a pivotable lever (40,41).  The roller diameter (46) is large in comparison to the length of the lever arm (40,41) and provides variable torque multiplication as the roller moves along the curved surface of the door (30) so that greater force is applied against the door when it is nearly closed.  Resilient seals (65, 70) are provided around the door opening, the seal compressed by the discharge doors during closing to prevent leakage.  The lever (40,41) is moved over-center to hold the door (30) in a locked position.

Abstract: DIGITAL TELEVISION TRANSMISSION USING CHROMINANCE INVERSION     Abstract of the Disclosure At a transmitter, an analog NTSC colour video signal is converted into a digital video signal and all of the signal components in the chrominance spectral band in alternate television frames are inverted. The resultant signal is transmitted via a low-speed digital signal transmission channel using interframe difference coding.  At a receiver, the received digital signal is converted into an analog video signal and all of the signal components in the chrominance spectral band in the other alternate television frames are inverted.  The resultant signal, having inverted chrominance, is reproduced on a conventional NTSC colour television receiver.  Bandpass and comb filtering, preferably on the digital signals, are used at the transmitter and at the receiver to separate the luminance and chrominance signal components to enable inversion of the chrominance components.                             - i -

Abstract: ABSTRACT OF THE DISCLOSURE      A rotary mower having a drive assembly which provides automatic de-clutching and prompt braking of the mower blade to a stop when the device is left unattended, while the engine keeps running.  A blade carrier is mounted on an anti-friction bearing at the lower end of the drive shaft. A driving hub is secured to the drive shaft at a level above the anti-friction bearing.  A shiftable shell of upwardly facing bowl shape surrounds the drive hub and defines a clutch space.  Mounted on the hub in the clutch space is a stack of clutch discs made up of a set of driving discs keyed to the hub and an interposed set of driven discs keyed to the interior of the shell.  The blade holder is keyed to the lower surface of the shell.  A set of springs on the blade holder urges the shell upwardly in a direction to apply clutching pressure to the discs for driving of the blade.  The shell has an annular lip or flange around its upper edge having a friction surface thereon.  A registering annular brake plate presses downwardly against the friction surface for braking rotation and for shifting the shell downwardly to release clutching pressure so that when the device is unattended the blade automatically comes to a stop.  A control member arranged for gripping by the operator during active operation holds the brake disc overpoweringly in an upraised position so that the blade is driven only as long as the control member is gripped.

Abstract: ACTIVE PREDISTORTER FOR LINEARITY COMPENSATION     Abstract A wideband amplifier utilizes predistortion components developed by an amplifying device similar to the power amplifying device to provide effective linearization for substantially reducing all of the intermodulation distortion products.  Since the compensation is provided at the input to the power amplifier, the need for an output signal combiner is obviated so that the total power is available at the output.  The efficiency is also enhanced since the predistortion amplifier which operates from the input signal only need be a voltage amplifier.  An optional feedback circuit is disclosed which may be employed to reduce nonlinearities further if necessary.

Abstract: ABSTRACT OF THE DISCLOSURE A method of reinitializing an elevator system upon the return to service of an elevator car following the occurrence of an event which could result in the car stopping in the hatch without regard to floor level.  The method includes the steps of determining if the elevator car is within  a predetermined  small  distance from any floor, and if it is, the advanced car position is set to that floor.  If the elevator car is not within this pre-determined distance from a floor, the advanced car posi-tion is set to the closest floor in a predetermined travel direction, such as the travel direction of the car at the time of the event which terminated normal operation.  The car is then moved to a predetermined floor, which is the floor of  the  advanced car position when there  are no registered hall calls,  and the floor of a predetermined car call, or hall call, when there is a registered call.

The auxiliary electrodes modify the electric field in such a manner that the elec-trons which are not captured in the tunnel of magnetic field lines are directed substantially towards the anode. The distance from the rod-shaped electrode the the sub-strate must be chosen to be comparitively small. By using the invention the substrate is less heated and not so much damaged by electron bombardment.
