Abstract: Abstract A system for automatically controlling the bias of a kinescope (15) in a television receiver comprises an input sampling amplifier (52), and an input clamping network including a clamp capacitor (51).  A reference voltage (VR) developed on the clamp capacitor is applied to the input of the sampling amplifier for establishing its initial reference bias condition.  The amplifier conducts during clamping and sampling intervals.  It samples signal amplitude changes referenced to the reference voltage provided via the clamp capacitor.  The amplifier is rendered non-conductive at other times, to thereby effectively decouple the discharge path for the clamp capacitor, whereby the clamp capacitor is prevented from discharging significantly during intervals when the AKB signal processor is not engaged in signal clamping and sampling functions.

Abstract: ABSTRACT OF THE DISCLOSURE         Method and apparatus for recovery of waste heat are provided herein.  A working fluid is delivered to a first branch in the system.          The working fluid in that first branch is then evaporated in an evaporator means by means of a waste energy source to increase the energy of the evaporated working fluid in the first branch.  The working fluid is received on a conduit and is delivered from the conduit and is delivered to an evaporator means, where the  evaporated working fluid is then compressed in evaporator means.  The compressed working fluid is then desuperheated in desuperheating means for desuperheating working fluid compressed by the first compressor means for delivering working fluid in the vapor phase to a second compressor means where the initial desuperheated working fluid is compressed.  That compressed working fluid is condensed in condenser means which receives the compressed working fluid from the second compressor means and which receives a second working fluid by transferring energy from the first-mentioned working fluid to the second working fluid whose energy is significantly increased.  That condenser means thus condenses the first-mentioned working fluid to the second working fluid.  The condensed first working fluid is delivered to desupercooling means in order to utilize the last-mentioned condensed working fluid to desuperheat the compressed working fluid.

Abstract: TITLE OF THE INVENTION:            VERTICAL MAGNETIC BRUSH DEVELOPING APPARATUS AND METHOD            ABSTRACT OF THE DISCLOSURE:      A magnetic brush developing apparatus is described which comprises a vertically positioned magnetic supply roll, a similarly positioned magnetic developer roll, and supply means such as a hopper for supplying magnetically attractable developer particles to the lower portion of the supply roll. The supply roll is provided with a magnetization pattern in which the magnetic poles are arranged in helical bands with respect to the roll axis. The developer roll has a symmetric magnetization pattern in which the magnetic poles are arranged in straight linear bands parallel to the roll axis. Developer particles move circumferentially and vertically upward on the surface of the supply roll and are transferred to the surface of the developer roll across a narrow vertical gap separating the two rolls. A doctor blade associated with the supply roll returns excess developer from the supply roll to the hopper. A second doctor blade associated with the developer roll, and positioned in proximity to the gap separating the supply roll from the developer roll, removes excess developer from the developer roll and allows the developer so removed to be magnetically attracted back to the supply roll. The developer is thus continually recirculated between the supply roll and developer-roll, and between the supply roll and the supply hopper, with the net amount of developer removed from the hopper being equal to the amount transferred to the recording medium by the developer roll.

Abstract: ABSTRACT OF THE DISCLOSURE         A film type multi-layered magnetic recording medium comprised of a film coated on a substrate in which coated film needle-shaped magnetic grains are oriented with their longitudinal axes perpendicular to the film surface in a multi-layered state and having the film thickness of 1.1 to 2.0 times the average length of the grains, has an excellent property in that the angular ratios (Br/Bs) of both horizontal and the vertical components respectively are 0.6 or more.  As a result, it is possible to realize the high density recording.         The film type multi-layered magnetic recording medium of the present invention is manufactured by applying a fluid film formation material in which needle-shaped magnetic grains are dispersed to form a coated film having the thickness of 1.1 to 2.0 times the average length of the magnetic grains on a substrate, and then drying or hardening the film formation material in a magnetic field perpendicularly oriented toward the film surface.

An input pulse of the shift register is formed according to the output from the counter and the timing pulse and the counter is reset according to the timing pulse and a clock pulse of the selection.  With such arrangement when the timing pulse is not generated, the counter will not operate and an effective input pulse to the shift register will not be generated and therefore the shift register will not sequentially read erroneous inputs and a plurality of shift stage outputs will not be generated at the same time.  In this manner, the selected circuits, elements, electrodes and drive circuit of power supply will be prevented from being damaged.
