Abstract: Abstract of Disclosure An apparatus for maintaining a predetermined liquid level within a tank while effecting the continuous addition and removal of liquid within the tank.  The apparatus is provided with a housing that mounts directly on a side wall of the tank with the housing extending on both sides of the wall, so that it is partially inside and partially outside the tank.  The housing has a first passageway which receives fresh liquid from a pressurized supply and introduces a portion of the fresh liquid into the tank.  The remainder of the fresh   liquid is provided to a second passageway which is connected between the first passageway and a drain.  The second passageway has a constriction near its inlet, which accelerates liquid flowing through it and injects the liquid into the second passageway at a high speed.  This produces a region of low pressure in the second passageway.  A third passageway is connected to the region of low pressure and its coupled to the water in the tank. By this arrangement, the low pressure is coupled to the third passageway, and is expelled to the drain.  In one embodiment, the apparatus in-cludes a mechanism for fail-safe operation in the event of excessive supply pressure build up.

Abstract: ABSTRACT           An axially fixed, radially limitedly movable stuffing box assembly including mounting means therefor. The stuffing box is adapted to have means for continuously flushing its bushing during operational rotational movements of a shaft functionally engaged therewith. The stuffing box when used in functional combination with a screw of a screw pump which is itself adapted for the pumping of high density fluids greatly reduces the tend-ency for radial forces generated during pumping to cause shaft deflection and to produce shaft wear and leakage.

Abstract: A B S T R A C T  A telephone office is provided with a dedicated trunk modified to transmit to subscribers lines connected to the same office the multifrequency tones from an outgoing sender used to identify the calling party.  Provision is made for connecting a subscriber's line pair to the dedicated trunk on provision across the pair of a special access code of pulsed or dialled digits.  The dedicated trunk is designed to provide the necessary signals to cause the outgoing sender to perform its functions.  A test set is provided for connection to a subscriber's line pair to dial the special access code.  The test set first tests for line conditions before dialling.  After dialling the test set detects the information in the multi-frequency tones originating with the outgoing sender.  At the telephone office an outgoing sender is preferably modified to send, in addition to the number of the calling party, the line location address of his pair of lines.  The test set also detects this information.

Abstract: SEPARATOR APPARATUS FOR DIFFERENTIAL HIGH   PRESSURE SYSTEMS OF A STIRLING ENGINE                 ABSTRACT OF THE DISCLOSURE            An improved dividing assembly, useful in dividing the high pressure gas system from the lubricating system in a regenerative type Stirling engine, is disclosed.  The closed thermally cycled gas system of a Stirling engine may vary between 20-200 atmospheres which complicates sealing and separation problems between fluid systems in the engine.          One interface between said fluid occurs at the piston rods which reciprocate between an oil flushed environment within the driven assembly and the pure high pressure gas environ-ment of the thermal cycling assembly.  The two systems must be separated and yet allow access of each system to said rods.          A piston rod sealing assembly is employed which uses a bleed of high pressure gas to (a) assist in forcing a tighter wiping of the piston rod surfaces, and (b) to convey wiped oil as a mixture away from the sealing assembly. A separator assembly is employed to reclaim substantially pure gas from said mixture and return separated oil to the oil system.  A control periodically returns separated oil, the float element of the control withstands high pressures of the fluids worked upon by use of a condensate confining zone within the float and an intercommunication between such zone and the float exterior so that upon the occurrence of a pressure differen-tial between the float interior and exterior, oil residue may be ejected and placed with oil separated by other filter or demisting means.

Abstract: ABSTRACT OF THE DISCLOSURE   Heavy metal ions are recovered from a dilute aqueous solution by flowing the solution through either a single bed of ion-absorbing material in successive forward and reverse directions, or through a first bed of ion-absorbing material and thereafter through a second bed of ion-absorbing material in the reverse direction of flow.  The reversal of flow is periodically to agitate mechanically a bed of ion-absorbing material to dislodge contaminants, such as gelatin.  The method is accomplished, by using one enclosed vessel, or a pair of enclosed vessels, that have valves to control the direction of flow.  A timing device preferably automatically reverses the direction of flow about each hour.  After a relatively large number of reversals of flow the heavy metal ions are recovered from the ion-absorbing material and the same is regenerated in the process to again absorb ions from the dilute aqueous solution.

Abstract: Abstract of the Disclosure The specification discloses a decoking apparatus suitable for use with a reaction vessel for the thermal cracking Of heavy petroleum oils.  The apparatus essentially includes a rotatable main injection pipe to ?? disposed in the reaction vessel and having a multitude of jet nozzles along its length, and a second or auxiliary injection pipe positioned in the proximity of the main injection pipe to inject a scrubbing liquid over the outer peripheral walls thereof to prevent deposition of coke on those walls.  The main and auxiliary injection pipes are both supplied with heavy petroleum oil to remove the coke depositions on the reactor wall by the heavy petroleum oil jets from the main injection pipe while wetting the outer peripheral walls of the main pipe with the heavy petroleum oil injected by the auxiliary injection pipe.  In this way, the coke deposit on the reactor walls can be removed simply, safely and economically without having to leave the reactor to cool before cleaning can be commenced.
