Granted: 1980-01-29
Abstract: ABSTRACT OF THE DISCLOSURE     Submerged arc welding process for 3.5% Ni steel which can provide a welded portion having a satisfactory impact resis-tance at low temperatures such as below minus 100°C.  In the process, use is made of a flux having a basicity as defined by a formula     in weight percentages of between 1.5 and 3.          The weld metal is deposited in a plurality of superimposed welded layers, each having a thickness less than 7 mm so that the weld metal in an underlying layer is thermally affected by an adjacent overlying layer whereby recrystallization is effected in sub-stantial thickness of the underlying layer to provide a fine crys-talline structure.

Abstract: ABSTRACT OF THE DISCLOSURE           A centrifugal rotor contains a member slidable axially of the rotor to open and close its peripheral outlets, and on the side of this member opposite from the separating chamber is an operating chamber for receiving liquid to main-tain the slidable member in its closing position.  Said member is moved to its opening position by draining part of the liquid from the operating chamber, the remaining liquid acting to return the slidable member to its closing position when only part of the material in the separating chamber has been discharged through the peripheral outelts. Means are provided for adjusting the magnitude of the force by which the slidable member is kept in its closing position, thereby enabling adjustment of the amount of material discharged from the separating chamber upon each opening of the periph-eral outlets.

Abstract: ABSTRACT OF THE DISCLOSURE          Disclosed is a method and apparatus for pressing and binding voluminous material into bales, in which material in the form of several layers is supplied through a closable opening into a pressing chamber where compression takes place of each supplied layer.  Final pressing is carried out at high pressure after a desired number of layers have been supplied into the pressing chamber, whereafter the pressing effect is lowered to a substantially lower pressure, so that the material compressed into a bale is permitted to expand, and the bale thereafter is discharged from said pressing chamber through a closable opening and bound while said substan-tially lower pressure is being maintained.

Abstract: METHOD AND APPARATUS FOR CONSERVATION OF ENERGY        IN A HOT WATER HEATING SYSTEM                     ABSTRACT OF THE DISCLOSURE           A very well heat insulated water storage or accumulator tank of relatively large capacity as compared to the capacity of the hot water heating unit is interposed between the unit and the radiator system and is interconnected with the unit.  Heated water from the top portion of the tank is used to preheat the unit prior to actuation thereof, and  mixed water above a given temperature is fed to the unit from the tank during actuation, such that the corrosive condensation on the heating surfaces of the heating unit, caused by heating a cold surface, is eliminated thereby extending the useful life of the unit.  When the unit is actuated, heated water from the unit fills the tank from the top side until a volume of non-heated return water from the radiator system, approximately equal to the capacity of the unit, remains in the bottom of the tank.  After the unit is deactuated, the non-heated water in the tank is utilized to cool the unit by replacing the heated water in the unit from the bottom side with cool water, causing the heated water in the unit to flow upwards into the tank.  The different operations form together a "heating cycle", which is repeated again and again and which is performed entirely automatically by an electric control circuit,  Energy is thus conserved because all of the heated water is utilized and the energy normally lost from a hot unit is significantly reduced. In this manner, the average efficiency of the system is greatly improved,

Abstract: UNIDIRECTIONAL OPTICAL DEVICE AND REGENERATOR Abstract of the Disclosure A light-activated light-emitting device has at least one p-n junction provided with electrodes for confining light-emission to an area of the junction. It has been determined that light-emission can be activated by light impinging on the junction outside this confined area, so two optical fibers are provided, one being an input fiber for bringing activating light to the nonemitting sensitive part of the junction and the other fiber being an output fiber coupled to the light-emitting area. When the device is a p-n-p-n light-activated light-emitting switch provided with an RCL reset control circuit, a very inexpensive unidirectional optical pulse regenerator is obtained. The device in its various forms is advantageously suited for use in each of many stations along optical fiber data busses or in optical logic arrays because the unidirectional feature prevents light feedback between adjacent devices and consequently avoids spurious switching of a preceding device.
