Abstract: ABSTRACT OF THE DISCLOSURE            In apparatus for bending a flat sheet of glass to a relatively sharp angle wherein the apparatus includes a sec-tionalized, gravity mold structure provided with means for sup-plying electrical power to electrical conductor lines formed on the glass sheet supported on the mold apparatus and which lead to an electrically conductive path also formed on the sheet along the line about which it is desired to bend the sheet.  Op-posed electrical contactors, forming a part of the electrical supply means, are urged into engagement with portions of the conductor lines leading to the path to provide continuous contact therewith and uninterrupted current flow during the bending oper-ation.  After bending, these contactors are displaced from such conductor lines into an out-of-the-way position for easy removal of the bent sheet and the replacement thereof with a fresh sheet.

Abstract: RCA 71,473 PAL SWITCHING CONTROL CIRCUIT     Abstract of the Invention In a PAL color television system for processing a color signal including burst and chrominance components alternating in phase at the image line scanning rate, identification and control circuitry for rapidly correcting an incorrect mode of line to line color demodulator switching.  A bistable circuit generates timing signals for controlling line by line switching of a selected color demodulator (e.g., R-Y).  An identification signal repre-sentative of an incorrect line switching mode is derived from information contained in the burst component, and serves to reset the bistable circuit such that timing signals corresponding to a correct switching mode are produced.  The identification signal is derived by a filter circuit exhibiting a fast response time relative to the line scanning time, in order to rapidly respond to the switching mode identification information occurring at the line rate and thereby rapidly restore the correct demodulator switching mode.

Abstract: ABSTRACT      Problems associated with the exact determination of position of a mine cage are overcome.   The sensors detect a magnetic striping on a rope arranged in a mine shaft and derive electrical signals indicative of the striping and thus the position of the mine cage. The signals are protected from common channel interference by circuitry and the position and direction of the cage are determined by a logic unit.   Error detection means detect circuit faults which could give rise to misleading positional data.

Abstract: Abstract of the Disclosure A testing and warning device for a vehicle according to the present invention is capable of checking a disorder in the vehicle in a sequential order through a dialog between the device and an operator.  The device first indicates conduction of a test before a starter is turned on and the operator depresses a test switch in compliance with this indication to test whether all indication units and buzzer can operate normally.  After finishing this test, any dis-order which may exist at various starting check points such as in the hydraulic fluid level or in the radiator water level is detected and indicated.  After the starting check up has been completed and the starter is turned on, operational check points such as the torque converter oil temperature  and the brake air pressure are constantly monitored and if there occurs any disorder in such check points, the operator is informed of such disorder by operation of all of the indication units and the buzzer.  The operator then operates a check switch whereby only the indication unit associated with the check point where the disorder has occurred is energized.

Abstract: CONSTANT TORQUE FRICTION CLUTCH                   ABSTRACT OF THE DISCLOSURE           A constant torque electromagnetically operated friction clutch including an axially moveable ferromagnetic armature drawn into frictional engagement with an inner body driving the output shaft upon energization of an electromagnetic coil.           The torque level transmitted is limited by an arrangement including an intermediate member which is rotatably connected to the armature by pins received at openings in the armature while allowing a predetermined extent of relative axial movement before heads on the pins abut the openings. The intermediate member is drivingly connected to the input member by camming balls which react to torque being transmitted, forcing the intermediate member to move axially, which movement is resisted by a spring force, When the intermediate member reaches the null extent of relative axial travel allowed by the pins, any increase in transmitted torque decreases the engage-ment pressure of the armature with the inner body set the maximum torque at that level.

Abstract: ABSTRACT OF THE DISCLOSURE           An air prefilter is disclosed for use with internal combustion engine air filters of the type having replaceable filter elements.  The prefilter has a perforated sleeve connected between the usual intake openings and the filter element of the conventional air filter.  This perforated sleeve is enveloped by an open-pore foam filter medium, which is of such porosity that engine intake air primarily passes there-through rather than through the intake openings of the conventional air filter.  The prefilter prevents foreign matter and water vapour from reaching and blocking the con-ventional filter element, which blocking causes the engine to receive insufficient air for efficient combustion.  When the prefilter medium is saturated or blocked with impurities, the conventional air filter operates as usual, until the prefilter medium is cleaned or replaced.  An adjustable deflector helps prevent foreign matter from blocking the prefilter medium.  Annular plates retain the deflector in position and help prevent foreign matter from entering the conventional filter intake openings.
