Abstract: ABSTRACT OF THE DISCLOSURE               A circuit breaker having a simple overload triggering mechanism of a thermostat element held at one end in a mounting member which is urged against a threaded rod by a spring. The other end of the thermostat element is notched to receive and engage a trip arm which is released to cause opening of the breaker contacts by bending of the thermostat element under overload current conditions.  When the trip arm is released it causes the mounting member to pivot.  The mounting member is adapted to engage the mounting member of an adjacent circuit breaker when the two circuit breakers are mounted in side-by-side relationship.  When either circuit breaker is tripped, pivoting of its mounting member pivots the other mounting member causing that circuit breaker to trip also.

Abstract: ABSTRACT   Remote units are connected in parallel to a monitoring and control center by a monitoring wire, a control wire, and a plurality of signal wave carrying wires each conveyinq signal waves of progressively doubled wave len-gth.  The remote units are each coded and identified by selectively routing one or more signal waves through an inverter at each unit so that the signal waves trigger an AND gate in a given time slot for each remote unit.  Accord-ing to the open/closed status of a  switch, the triggering of an AND gate sends a signal through the monitoring wire for each unit in the time slot for that unit.  The center sequentially monitors each remote unit in its tine slot and indicates its status.   Each remote unit may include a relay which is act-ivated from the center through the control wire during the time slot for that unit.  At the center a relay operated switch and a connection may be added to enable a status of one remote unit to control another remote unit.

Abstract: ABSTRACT      Disclosed is a covering for a substrate which may be a shedded electrical insulator.  The covering is formed, e.g. by moulding, of heat recoverable material and has internal transverse dimensions (diameter, if round) slightly smaller than the transverse dimensions of the substrate.  The covering is converted to a heat-recoverable form by heating, expanding on a mandrel and cooling, followed by removal of the mandrel.  The covering is then placed over the substrate and heated to shrink it tightly around the substrate, there being a small amount of unresolved recovery.

Abstract: Abstract.           Apparatus for conveying an elongated hot-rolled steel rod in off-set ring form on a conveyor through a series of cooling chambers.  Each cham-ber comprises a stationary lower section and a removable cover section, the interior walls of each being heat reflective.  Each chamber is also provided with tubes supported adjacent the interior walls and controlled in temperature by gas passing through said tubes, said gas being cold or hot, the hot gas being supplied from a plurality of separately controlled burners. The tubes differentially control the rate of heat radiation from the rod rings to com-pensate for the different rates of radiational heat loss emanating from the top and sides of the rod rings so as to cause the rod to cool uniformly.  The side walls of the chamber are provided with adjustable apertures for the escape of radiant energy from the sides of the rod rings.  Means are provided for controllably lifting the roof from its completely closed position to one in which the of the lower section is entirely exposed.  Means are also provided for blowing cooling air through the rings.  The apparatus provides means for carrying out a process for controlling the loss of heat from the rod by applying radiant heat selectively to the rod, by reflection from the interior walls or by the heated or cooled tubes, or both, substantially in inverse proportion to the accumulated mass of the rod iron side to side of the conveyor.

Abstract: ABSTRACT OF THE DISCLOSURE       The minimum and maximum values attained by an analog data signal in each of successive sampling periods are determined by alternately operative amplitude detectors which produce and store a corresponding minimum and maximum signal for each of these periods.  A generator produces a ramp signal which repeats in each period in synchronism with the sweep of the beam of a fiber optics strip cathode ray tube along the strip thereof.  A record sheet is advance at right angles to this strip.  Comparators are operative in each period to compare the stored detector signals of the immediately preceding period with the ramp signal, and to produce an output when the ramp signal exceeds either of the detector signals.  An EXCLUSIVE OR gate receives these outputs and unblanks the normally blanked tube beam for a time in each period to produce a line on the sheet extending along the strip between points representing the minimum and maximum signal values for the preceding period.  The successive lines of the successive periods combine to form a recorded curve for the data signal.

Abstract: ABSTRACT OF THE DISCLOSURE          Crumbled cheese curd is fed into the top of a hollow column in a chamber maintained at a sub-atmospheric pressure so as to form in the column a pillar of curd devoid of air pockets, the curd in the lower portion of the pillar being compressed by the weight of superimposed curd to press out whey therefrom and consolidate the curd, and the pillar of curd a is repeatedly lowered, the bottom and of the pillar severed to form a block of cheese, and fresh curd added to the top or the pillar.  During the lowering of the pillar of curd, the top of the pillar is subjected to a higher pressure than that acting on the bottom of the pillar so that the differential pressure exerts a force on the top or of the pillar urging the pillar downwards and prevents fracture of the pillar due to frictional resistance with the walls of  the column.  The curd is fed into the chamber through a feedpipe connected between the top of the chamber and the outlet of a hopper containing curd under atmosphere pressure, the differential pressure between the hopper and the chamber causing curd to flow along the feedpipe.  The feedpipe discharges into a cyclone separator in the top or the chamber for separating air form the curd.

Abstract: ABSTRACT OF THE DISCLOSURE           In the gas shielded arc welding method for a long seam of formed pipe and the like, the improvement is provided wherein a welding voltage-current and shielding gas is established to produce incomplete short circuiting transfer, such that the welding arc is maintained and the voltage does not drop to OV as compared with the prior short circuit method in which the arc is interrupted and the voltage drops to V; in this way it is possible to employ high speed welding, with high speeds of more than at least 3m/min, especially, 5m/min; the method also has advantages over the prior spray transfer method where voltage and current are maintained essentially constant but high speed welding is not possible without formation of a strong plasma jet which blows off the molten metal to expose the seam.  The incomplete short circuit transfer lies intermediate the spray transfer weld region and the short circuit transfer weld region of the prior art.

Abstract: PROCESS FOR SEPARATING ACID GASES AND    AMMONIA FROM A DILUTE AQUEOUS         SOLUTION                 ABSTRACT OF THE DISCLOSURE           A water purification process is described for the removal of ammonia and optionally one or more acid gases from waste waters such as coke-plant or coal conversion waste waters.          The process involves adding lime to these waste waters in amounts sufficient to react with fixed ammonia salts present in the waste water and to enable substantially all of the ammonia to be evolved upon distillation, adding a threshold amount of a scale inhibitor compound chosen from the class of certain organic phosphonates and subjecting the thus treated waste water to distillation to remove substantially all of the ammonia and acid gases present from the waste water.  Preferably, this process is achieved by two separate and successive distillations.  In this preferred process, the first distillation substantially reduces the amount of the acid gases and free ammonia.  In the second distillation, the amount of fixed ammonia is substantially reduced.
