Abstract: ABSTRACT OF THE DISCLOSURE      A vehicle transmission with an automatic clutch is disclosed in which for gear shifting the clutch is disengaged with the assistance of a vacuum of a source of vacuum, via a control valve having a solenoid actuated clutch release valve and a clutch serve. disengagement of the clutch is carried out when a gear shift lever is manipulated with an engine accler-ater released.  The reengagement of the clutch commences as seem as the flow of current to the solenoid for the clutch release valve is cut.  The clutch release valve then disconnects the clutch serve form the source of vacuum.  The reduction of the vacuum in the clutch serve takes place in two stages. In the first stage, the vacuum is reduced very quickly by means of a selenoid actuated air-on (air bleed) valve for a predetermined time after the flow of current to the selenoid for the clutch release valve has been cut until the clutch begins to engage or is about to engage.  Current is supplied to the solenoid for the air-on valve when current is supplied to the solenoid for the clutch release valve.  A delay means is pro-vided whereby, after the predetermined time after the flow of current to the selenoid for the clutch release valve has been cut, the flow or current to the solenoid for the air-on valve is cut.

Abstract: 25.5.77 ABSTRACT:         In a ground proximity warning system used in aircraft to warn of the proximity of dangerous terrain conditions by reference to specified flight warning mode envelopes, an automatic diagnostic sys-tem is used to monitor system errors, particularly in the acquisition channels for analog input para-meters HR, HB and GS which are monitored continuous-ly at all altitudes. The diagnostic system substitutes test values for the said parameters which are com-pared against stored reference values, the results being displayed in diagnostic form after filtering by a time constant which takes into account the ef-fects of transient errors. In addition to diagnos-ties visually displayed both on the front panel of the system and in the cockpit of the aircraft in a manner which defines non-operational parameters and flight warning modes, back-up diagnostics in the form of crew initiated audio test sequences are provided.

Abstract: Each zone of a double-detecting loop type alarm system utilizes a current level detector to produce a digital signal when normal current flow in the detecting loops is interrupted.  The digital signal so produced is stored in a holding register. whose output drives electronic shunting switches con-nected across the ends of the detecting loops.  Closing of the switches per-mits current to again flow to the current level detector and detecting loops, causing the current to return to a normal current level if the interruption was caused by a break or short in a detecting loop; this permits that zone of the alarm system to again function,  since the system is digital. its out-puts and those of the other zones are presented by means of other digital transmitting and monitoring devices, such as a binary multiplexer.

Abstract: AUTOMATIC CHROMINANCE GAIN CONTROL SYSTEM                Abstract of the Disclosure An automatic gain controlled chrominance signal amplifier system for a color television receiver is arranged to process composite chrominance signals having burst and image representative components.  First, second and third amplifier stages are provided for amplifying the image-representative components.  The first amplifier also amplifies burst components and is gain controlled in a first closed loop arrangement to maintain a substantially constant amplitude for the burst component and to thereby maintain an appropriate gain for image components.  The second and third amplifiers are coupled to the output of the first amplifier.  The output of the second amplifier is coupled to a chrominance signal overload detector arranged to respond to image-representative signal components having peak amplitudes greater than a pre-determined level.  A gain control output provided by the overload detector is coupled to each of the second and third amplifiers to vary their gains in a manner to prevent undesired oversaturation of the displayed image.  A further gain control adjustment (e.g., viewer operated) is coupled to the third amplifier but not to the first or second amplifiers.  Apparatus is also provided for shifting the operating threshold of the overload detector.

Abstract: Abstract of the Disclosure:         A compact resistor device comprises a body of ceramic material of positive temperature coefficient of resistivity having a large number of passages extending through the body between opposite ends of the body, thereby forming very thin webs of the resistor material between adjacent passages.          Coatings are formed on the resistor material along the inner walls of the passages to serve as ohmic contacts.  The coatings in alternate passages are connected together at one end of the resistor device and the coatings in the other passages are connected together at the opposite end of the device to serve as device terminals.  When the device terminals are connected to a power source, current flows through very thin webs of resistor material between ohmic contacts in adjacent body passages.  The resistor device is particularly useful in current limiting applications requiring low, room-temperature resistance and in heat-exchanger applications where a fluid to be heated is directed through the passages.

Abstract: RCA 72,353 HIGH POTENTIAL, LOW MAGNIFICATION ELECTRON GUN                   Abstract The electron gun, which is especially adapted for use in color picture tubes, comprises in the order named: a cathode, an apertured-plate control grid, an apertured-plate screen grid, and at least two tubular focusing electrodes.  The quality of the gun's beam spot is improved by:  1.  Establishing an operating electric field between the screen grid and first focusing electrode which is between about 100 and 400 volts/mil (3937-15748 volts/mm), thereby reducing aberration effects in the beam-forming region of the gun; 2.  Making the screen grid thick so as to prevent the high first focusing electrode voltage from penetrating the region between the control grid and screen grid, thereby allowing the control grid-screen grid field to provide a divergent effect on the electron beam prior to beam crossover and thus give a reduced crossover angle;  3.  Elongating the first focusing electrode to provide an optimum filling of the main focus lens with the beam to maximize the object distance of the focusing system; and 4.  Structuring the screen grid and first focusing grid to provide a flat electrostatic field therebetween to avoid prefocusing action in that region, so as not to cause an effective reduction of the object distance of the focusing system.
