Abstract: ABSTRACT OF THE DISCLOSURE Disclosed herein is a process for recovering a phosphate ester type hydraulic fluid from a waste liquid con-taining water, organic solvents and other impurities, such as polychlorinated biphenyls (PCB).  After filtering to remove parciculate matter, a heavy fraction separated from the waste liquid and consisting primarily of the hydraulic fluid is first subjected to a distillation step.  A substantial portion of the PCB 's removed as overhead from the distillation step and the bottoms containing the hydraulic fluid is subsequently evaporated, preferably in a thin film evaporator. The over-head from the evaporation step is condensed to recover the hydraulic fluid.

Abstract: EXCESS FUEL STARTING DEVICE FOR FUEL INJECTION ENGINES                   ABSTRACT OF THE DISCLOSURE       An excess fuel starting device for a fuel injection engine having a full load stop coacting with the engine throttle link-age to limit the fuel input from the fuel injection pump to the engine.  A hydraulic actuator positions the full load stop in either a normal run position or an excess fuel position.  The actuator includes a cylinder containing an excess fuel piston operatively connected to the full load stop and spring biased toward an excess fuel position.  A coaxial bore within the ex-cess fuel piston contains a free piston slidable therewithin. Fluid conduit means is provided for delivering a fluid pressurized during engine operation to actuate only the smaller free piston when the actuator is in the excess fuel position.  Then the ex-cess fuel piston has been moved by the action of the free piston to the normal run position, the fluid conduit means delivers the pressurized fluid to provide a holding force against the larger excess fuel piston.  The differential in the actuating pressure versus the holding pressure of the device may be varied to suit the installation requirements by the choice of the re-lative diameters of the excess fuel and inner pistons.

Abstract: ABSTRACT OF THE DISCLOSURE           A solar heating system for a swimming pool and the like is disclosed.  The system includes a circulation circuit having a pump by which water is withdrawn from the pool, passed through a filter and returned to the pool.  A solar collector assembly is provided and has flow and return lines connected in said circuit.  The flow line is connected to a venturi unit in the main circuit and a control valve is provided immediately downstream of the venturi unit.  When the control valve is closed, water is diverted through the venturi unit and into the solar collector assembly for heating.  When the valve is open, the venturi unit induces a suction effect in the flow line which causes the solar collector assembly to be positively drained into the circuit.  A vacuum breaker admits air to the collector assembly at this time.

Abstract: BALLAST CIRCUIT FOR ACCURATELY   REGULATING HID LAMP WATTAGE     ABSTRACT OF THE DISCLOSURE         Circuit for regulating the wattage drawn by a high-intensity-discharge (HID) lamp and for limiting the line current drawn by the lamp during starting to less than the line current drawn during normal lamp operation.  The circuit includes a lamp current controlling means which has two oper-ating modes, a first of which passes a less-than-nominal current to the lamp and a second of which passes a greater-than-nominal current to the lamp, with the ratio of the cur-rent of the second mode to the current of the first mode being less than 2:1.  The lamp voltage is sensed and the line voltage also is sensed and these parameters are converted into separate current signals which are fed into a ramp cap-acitor to control the charging rate thereof. When the ramp capacitor achieves a predetermined level of charge during each half cycle of energizing potential, an AC switch is gated to shift the current controlling means from the first mode to the second mode.  During lamp starting when the volt-age drop thereacross is relatively low, the current controlling means remains in the first mode for at least the substantial portion of each half cycle of energizing potential, and after the lamp is normally operating, the ramp capacitor control, coupled with the low ratio of relative currents passed by the current controlling means, provides for an accurate control of lamp wattage and excellent overall performance.         This application is a continuation-in-part of apply-cation S.N. 776,804 filed March 11, 1977 by Joseph C. Engel and Robert T. Elms, the present applicants, and owned by the present assignee.

Abstract: ABSTRACT            The invention concerns a method and apparatus for severing the jowl muscles of a half pig's head, in order to facilitate subsequent boning of the half head to provide bone and pig's head meat as the end product.            For this purpose, in one embodiment of the invention, the half pig's head (19) is placed on a moving conveyor (11) comprising a series of stainless steel plates (12), the half head being held securely in a predetermined position by a locating and supporting means (13 to 18) welded to the plate (12).  The half head so held is presented by the conveyor to a fixed wedge member (20) pointing in the opposite direction to that of the conveyor movement, the wedge member acting to force the jaws of the half head progressively further apart to sever the jowl muscles.            Preferably, the outer skin or rind of the half head is removed before the latter is placed on the conveyor.  This is achieved manually by an operative using a knife, the half head during this operation being placed on a table (26) and held in position by a wire loop (28) which holds the snout of the half head tightly against a post (27).

Abstract: RD 10,960 ABSTRACT OF THE DISCLOSURE A device for detecting alkali metals in gas streams includes a conduit defining a gas-flow cavity.  A metalliferous filament having a work function of at least 5.3 ev is located within the cavity and extends transversely through the gas flow path a low-voltage source connected to the filament to a temperature sufficient to ionize the alkali metals being detected.  An electrically conductive ion-collection member surrounds the filament to define an ionization-collection region.  A high-voltage source develops an electrical field within the region, thereby effecting neutralization of metal ions attracted to and contacting the ion-collection member.

The apparatus includes a capacitor having first and second terminals, the first of which is coupled to a substantially planar plate of the capacitor.  The first terminal is coupled to the circuit connection point, which may otherwise act as an RFI antenna.  The second capacitor terminal is coupled to a point of reference potential for radio frequencies.  The capacitor is oriented when mounted so that the planar plate opposes and is substantially parallel to a metallic surface which is at the radio frequency reference potential (e.g., ground).  The capacitor suppresses RFI radiation from the circuit connection point by conducting a portion of the RFI energy at that point to the point of RFI reference potential by way of the first terminal, the body of the capacitor, and the second terminal.  A second portion of the RFI energy at the circuit connection point is radiated from the planar plate of the capacitor to the opposed metallic surface.

Abstract: Abstract of the Disclosure A process for producing a binder (cement) to be used in slurry, mortar, or concrete having a low water-to-cement ratio.  As raw-material for the binder is used at least 50 % by weight of a hydraulic material, such as slag, technical pozzolanas and/or natural pozzolanas.   The hydraulic material is ground to a specific surface of at least 400 m2/kg.  To the raw-material is added 0.1 to 5 % by weight of a plasticizing material, such as a sulphonated polyelectrolyte.  To the raw-material are also added in total 0.5 to 8 % by weight of sodium carbonate and/or sodium hydroxide.  Added in small amounts, the sodium carbonate and the sodium hydroxide, separately or in combination, considerably shorten the hardening time of the concrete, yield excellent strengths, and make it possible to use cheap raw-materials.
