Abstract: ABSTRACT OF THE DISCLOSURE         A portable alarm which comprises an electro-mechanical switch, at least one cord and a cord-retaining member.  The switch has a cock member slidable in a first slot and a trigger member slidable in a second slot intersecting and oriented at right angles to the first slot.  The switch further has a pair of normally opened electrical switch terminals registering with the inner end of the first slot.  The cock closes the switch terminals when released by the trigger member.  Both members are inwardly biased.      The release of the cock member is achieved when the tension of the cord connected between the trigger member and the cord-retaining member is slightly changed.  The cord-retaining member is attached to an object to be protected,such as a window or a door.      The electrical plugs are connected to a power source and to an eletric alarm, respectively.

Abstract: ABSTRACT OF THE DISCLOSURE A process for carrying out radical-enhanced combustion of fuel in an engine according to which hydrocarbon radicals generated during one combustion cycle in an engine working chamber are seeded in the charge supplied to the working chamber during a subsequent cycle. The radicals are stored and protected in an air chamber within the piston beneath a piston cap element between combustion cycles. Combustion is initiated very close to the radical-enhanced autoignition temperature of the charge, and ignition may be by spark or by compression effects, depending upon the temperature of the charge. The temperature of the charge in turn is controlled by controlling the air to fuel ratio of the charge. If the cycle is carried out in the autoignitionmode by compression effects, the cap material is selected to yield best power output for the fuel used by, and the compression ratio of, the engine. The radicals consist of a mixture of pre-flame and post-combustion radicals and are seeded into the intake charge by wave interaction between the working chamber and the air chamber across a restricted orifice.

Abstract: ABSTRACT OF THE DISCLOSURE A gas lock breaking device for use in well pumps having a standing valve and a piston equiped with a traveling valve.  The device includes a valve closure unseating rod which is adapted to be attached to the standing valve so that it is unyielding with respect to the standing valve.  The traveling valve has a ball valve situated within an elongated cage, with a valve seating means at the bottom of the cage having an opening to permit entry of the unseating rod into the cage during each stroke of the pump. The length of the rod and the cage are such that at the extreme downward position of the traveling valve, the ball valve is unseated by the rod without being impacted against the top of the cage by the rod.  The upper end of the rod includes a dished portion which tends to distribute the contact between the rod and the ball valve and tends to maintain the ball valve in the central area of the cage.  The rod causes the traveling ball valve to be positively unseated during at least a certain portion of the cycle to allow escaped gases in the area beneath the traveling valve.

Abstract: LIVESTOCK FEEDING APPARATUS Abstract of the Disclosure A livestock feeding apparatus which includes an endless belt conveyor.  Feed is supplied to the upper run of the belt and is selectively discharged from either side of the conveyor belt by a feed dis-charge unit.  The feed discharge unit includes a frame mounted to travel in a reciprocating path above the belt and the frame carries a feed diverting plow and a rotatable brush.  The plow and brush are disposed in generally parallel arrangement and can be pivoted be-tween a first diagonal position with respect to the side edge of the belt to a second diagonal position. Movement of the conveyor belt is transmitted through a drive mechanism to rotate the brush about its axis.  As the feed discharge unit moves relative to the belt, feed is discharged from the side edge of the moving belt by the plow and the brush acts to remove residual feed from behind the plow.  When it is desired to feed from the opposite side of the belt, the feed discharge unit is moved to the feed end of the conveyor and as it reaches its end point in its reciprocating travel and is reversed a shifting mechanism is actuated to pivot the plow and brush so that continued relative movement between the feed distributing unit and the conveyor will cause the feed to be distributed to the opposite side of the belt.
