Abstract: TIMING MECHANISM WITH TWO SEPARATE PROGRAMS OPERATING SEPARATE SWITCH ACTUATORS         AND HAVING AN ALARM SYSTEM                            ABSTRACT OF DISCLOSURE         First and second movable spring contact blades are disposed in substantially parallel relation and have substantially equal lengths with electrical contacts disposed near their distal ends.  A third spring contact blade having electrical contacts at its distal end is fixedly disposed between the first two blades and has a shorter length than the two blades to provide a gap between the first two.  The elec-trical contacts are in line with and facing each other at a distance just short of the gap.  The combination of the electrical contacts provides a double pole switch means.  Two independently operable actu-ator arms enter the gap to selectively engage the first and second spring contact blades to selectively open and close the electrical contacts.  The two actuator arms in combination with the electrical contacts provide a program of a short pulsing duration within a longer program.          There is a selector means which permits the actuator arm for the shorter duration to be operably removed from the system.          One of the two actuator arms is responsive to a sharp drop in a step of a cam means, the arm engaging the bottom of the step to limit its travel.  A striker carried by the arm continues in the direction of the drop to engage an alarm means.

Abstract: PIT AND FISSURE SEALANT FOR TEETH                        Abstract An inorganic, enamel-like sintered coating (or sealant) adherent to teeth is disclosed.  Materials very similar to tooth enamel, e.g., hydroxyapatite, combined with a low melting eutectic constitute the coating.  This material can be applied to the tooth and sintered in place with a laser.  The presence of the low melting eutectic lowers the energy requirement for sintering.

Abstract: ABSTRACT OF THE DISCLOSURE           A protector means is provided to prevent thermal destruction of a solenoid adapted for very short duration energization at currents far in excess of the continuous current carrying capability of the solenoid.  The protector means includes a positive temperature coefficient thermistor which controls the gate potential of an S.C.R. whose power circuit is in series with the solenoid.  When thermistor temperature rises to a predetermined level the voltage applied to the gate drops below the gate threshold thereby preventing the S.C.R. from firing on the next positive half-cycle.

Abstract: ABSTRACT OF THE DISCLOSURE     A valve with a tapered plug 36 that seats in a through flow passage 34 in the body 12.  The plug has a through opening so that by rotating the plug through 90° one can control flow through the valve.  The plug is tapered and, as it is rotated in the counter-clockwise direction to open, it is also lifted slightly from its seats by rotation of the stem 26.  As it is rotated in the clockwise direction to close, the plug is pressed slightly down to form a sealing engagement with its seat in the body.  The combination of rotational and vertical movements - in effect a spiral motion -of the plug provide a valve that has an effective seal, ease of manipulation and full throttling with 1/4 turn of the tapered plug.  The plug is mounted on a stem 26 which, in turn, threadedly engages with a mounting nut 46 that can be threadedly set in a seat on the body with any desired seating pressure of the plug on the plug seat in the body and then clamped in position as the valve is assembled.

Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus are disclosed for achieving improved reduction efficiency and thermal economy in the re-duction of particulate metal ores, e.g., iron ore, in a vertical shaft, moving bed reactor.  The reactor consists of a primary reduction zone, a cooling zone and a secondary re-duction zone located between the primary reduction zone and the cooling zone wherein ferric carbide formed in the primary reduction zone further reduces the residual iron oxide in the presence of an inert gas at a temperature below the melt-ing point of the sponge iron.  In one embodiment of the in-vention the gas produced by the reaction in the secondary re-duction zone is withdrawn into a combustion chamber where it is mixed with air and burned, carbon dioxide is removed from the effluent gas of the combustion chamber and the remaining inert gas is recirculated to the secondary reduction zone. In another embodiment of the invention inert gas is supplied from an external source and carbon dioxide is eliminated fro the system by means of a controlled purge.  Use of the dis-closed secondary reduction system allows for a lower residence time of the metal ore through the reactor and in-creased thermal economy.

Abstract: ABSTRACT OF THE DISCLOSURE:          A no-drip valve apparatus for regulating a fluid flow from an inlet to an outlet.  A pressure activated supply valve means controls the flow of fluid through the valve.  A partition member cooperates with a vacuum chamber to retract and retain any remain-ing oil in the valve or the outlet nozzle when the pressure activat-ed supply valve means cuts off the flow of oil through the valve.          The partition member is resiliently displaced by pressure fluid from a supply chamber adjacent the inlet and is displaced in one direction prior to flow of fluid to the outlet and is displaced in the other direction upon termination of the flow of fluid through the outlet.

Abstract: Abstract of the Disclosure A method for controlling a scintillation camera has a step of, under the control of a CPU, displacing a radiation source displacing device to which is fixed a radiation source and obtaining a center of sensitivity of a photomultiplier tube to be measured.  After the center of sensitivity including the effects of the waveform shaping circuit is obtained, the radiation source is displaced in a plurality of directions relative to the center of sensitivity under the control of the CPU, so as to obtain an average photomultiplier tube response (PMT response) as a function of distance from the center of sensitivity of the photomultiplier tube. The CPU compares the obtained average PMT response with a reference PMT response which provides an image of optimal uniformity to obtain data by which the average PMT response approaches the reference PMT response. Based on this data, the CPU obtains parameters of the waveform shaping circuit to provide a response close to the reference PMT response.

Abstract: Abstract of the Disclosure An ocean mining system for mining manganese nodules comprises a sur-face subsystem and an ocean bottom subsystem. The ocean bottom subsystem includes a mobile maneuverable, self-propelled, miner vehicle which picks up, handles, washes and crushes nodules while retaining nodule fines.  The under-water subsystem also includes a buffer which functions to provide temporary storage for nodule material picked up and crushed by the miner vehicle.  The buffer further serves to isolate the miner vehicle from the  dynamics of a pipe string extending down from a surface ship.  All equipment not needed for operation of the miner vehicle is located on the buffer to distribute the weight between the buffer and the miner vehicle in a way that provides maximum mobility of the miner vehicle.  The underwater subsystem also includes a flexible link-age, extending between the  miner vehicle and the buffer  A flotation block holds the flexible linkage up and out of the way of the miner vehicle during operation of the vehicle.  This flexible linkage permits operation of the miner vehicle within a boundary envelope beneath the buffer as determined by the flexible linkage.  The surface subsystem includes a ship which provides all operational control and maintenance support for the bottom subsystem.  The ocean mining system includes sensors and controls.  The sensors sense the location of the miner vehicle within the permitted area of operation, display the topography of the ocean floor adjacent the miner vehicle and also display all aspects of the movement of the miner vehicle and pick-up and handling of the nodules.  The controls provide active control of every com-ponent of the  ocean bottom subsystem from the surface ship.
