Abstract: ABSTRACT OF DISCLOSURE           A system for automatically adjusting the height of a vehicle wherein a polarity-determination pattern detector and an allowable-displacement pattern detector are disposed in confronting relation to and movable relative to a pattern plate in parallel directions in response to variations in the height of a vehicle.  The pattern plate has a polarity-determination pattern having one end posi-tioned in confronting relation to the polarity-determination pattern detector and extending in a direction of movement of the pattern plate, and an allowable-displacement pattern having a center thereof positioned in confronting relation to the allowable-displacement pattern detector and extending in the direction of movement of the pattern plate.  The pattern plate may be provided with a plurality of such polarity-determination and allowable-displacement patterns.          An electrical circuit generates a signal indicative of an increase or decrease in the vehicle height depending on whether or not there is an output signal from the polarity-determination pattern detector when there is no output signal from the allowable-displacement pattern detector for a predetermined interval of time.  With such an ar-rangement, the vehicle height can automatically be adjusted even while the vehicle is running.

Abstract: ABSTRACT OF THE DISCLOSURE       Tires made using polyester cord in the fabric plies are built in a conventional manner, cured in a conventional manner in a curing press, removed from the curing press and held in an uninflated state for a length of time sufficient for the tire to cool to 300°F (149°C), then post inflated.  The tires remain in the inflated state until the temperature has been reduced below 90°C.      The cords in the tires which have been subjected to the post inflation treatment of the present invention have less tendency for sidewall waviness than tire which have been post inflated out of the mold immediately after curing and without being subjected to cooling water in the bladder.  Also the cooling period outside the mold has been found to be as successful in solving the sidewall waviness problem as the injection of cooling water into the bladder for 2 minutes at the end of the cure cycle.

Abstract: SAFETY CONTROL FOR AUTOMATIC DISPENSING GUN            Abstract of the Disclosure An automatic safety system is built into a pneumatic motor actuated dispensing gun to prevent the gun from dispensing liquid material whenever the nozzle of the gun is loosened or re-moved from the gun body.  The safety system comprises an air flow passage contained internally of the gun body for connecting the pneumatic motor to a normally sealed surface located between the nozzle and the gun body.  Removal or loosening of the nozzle relative to the body, breaks this sealed surface and results in leakage of sufficient air pressure to atmosphere as to prevent actuation of the pneumatic motor and thus opening of the normally closed flow control valve of the gun.

Abstract: ROOF BIT COUPLING                      ABSTRACT          A quick release, high torque coupling for interconnecting the bit and drive member in a mine roof drill has axial-locking and torque-transmitting structure integral with the drill members.  A plug on the drive member is adapted to be releasably received within a mating socket in the bit and has an axial-locking segment on its outermost end complementally configured with respect to an acircular constriction in the socket to permit insertion of the axial-locking segment into the socket beyond the constriction.  A torque transmitting segment on the plug cooperates with the constriction to limit relative rotation of the bit and drive member between oppositely directed torque-transmitting positions.  In one of the torque-transmitting positions, the constriction and axial-locking segment are misaligned such that the plug is restrained against axial retraction from the socket.

Abstract: ABSTRACT OF THE DISCLOSURE           A support member for horizontal members or elements in a traversable opening covering device is disclosed.  In the preferred embodiment, the opening covering device is a vertical blind for a window opening.  The vertical blind includes a plurality of vanes and carriers supporting the vanes, and a track structure for traversably supporting the carriers.  The rod controls movement of the vanes, i.e. traversing or rotating of the vanes.  In the preferred embodiment, the carriers are traversed by a cord arrangement and the support member also supports the cord.  The support member comprises a body having an opening therein adapted to slidably receive the horizontally extending rod, shoulders or rollers disposed on opposed sides of the body adapted to be traversably received in the track structure, and another opening or a spring arrange-ment associated with the body adapted to receive a cord therein which is used to traverse the carriers and which is releasably and frictionally engaged with the opening or spring arrangement.          Movement of the cord traverses the carriers and also traverses the support member from one end of the track structure to a predetermined supporting location at the central part of track structure.  The support member is retained at the predetermined location at the central part of the track structure when the frictional engagement between the cord and support body is over-come so that further movement of the cord traverses the carriers but not the support member.
