Title: Iron self-clean valve assembly
Inventor: WALKER WENDELL C
IPC: D06F75/18
Filed: 1978-09-08
Granted: 1980-04-15
Abstract: ABSTRACT OF THE DISCLOSURE         A steam iron is disclosed having a water tank, steam generating soleplate, a guided water valve to start and stop water to the soleplate for steam generation, and a dumper valve in the bottom of the tank to suddenly empty the tank onto the soleplate to purge and clean the iron.          To this conventional structure an improvement provides a unitary assembly of the dumper valve that includes a first tubular member with its upper end connected to the bottom of the tank and its lower end extended below the tank towards the soleplate.  Cooperating with this is a second concentric tubular member telescopically disposed frictionally with the first member so the two tubes are pushed and locked together.  Each of the members has an inwardly directed flange at one end and at the opposite end from the other so that the flanges define reduced openings at the upper and lower tubular ends.  A movable flat valve disc spans the upper opening below its flange and a spring is provided below the disc to bias it closed whereby subunit that may be fixedly locked in the tank bottom and is movable to suddenly empty the iron.

Abstract: PHD. 77-159.           ABSTRACT:      In the device according to the invention, a body is irradiated by a small cross sectional primary radiation beam.  The scattered radiation produced thereby, being incident via a slit on a detector device consisting of a plurality of elongate detectors parallel to the slit and transverse to the beam, is a measures for the density distribution in the primary beam.  However, this gives rise to multiple scattered radiation which disturbs the measuring result.  The present invention provides a device in which this disturbance by multiple scattered radiation is greatly reduced, without there being any significant effect on the scattered radiation directly originating from the primary beam.  To this end, a device in accordance with the invention is provided with pre-ferably flat laminations which are arranged between the primary beam and the detector device and which are situated, starting from the primary beam, in a fan of flat planes transverse to the slit. Contrary to a customary scattered radiation grating, the lamination device need not be moved during customary X-ray exposures. The laminations must be adapted to  the substantially harder radiation.

Abstract: ABSTRACT OF THE DISCLOSURE         A limited-channel tuning system for a television receiver includes a memory whose activation time is directly related to its useful life.  A channel address information means is coupled through an encoder to a series of flipflops which supply a first set of inputs of a corresponding plurality of comparators.  The encoder also directly supplies a memory-accessing decoder and second set of inputs of the comparators.        The outputs of the comparators are coupled through a NOR gate to a flipflop.  The output of the flipflop supplies one input of an AND gate.  A clock source drives all flipflops and the other input of the AND gate.  The output of the AND gate drives a one-shot multivibrator for activating the memory with a short duration Read pulse only after a change in channel address input information occurs.

Abstract: ABSTRACT              This invention relates to a method for neutralizing and collecting oil from oil spills and to a composition used in such method and to a combustible product produced by such method.  In accordance with the method of this invention in one aspect, diatomaceous earth is used to absorb and adsorb oil from the oil spills in a proportion which will provide a clay-like product.  This clay-like product can readily be removed.  Where the oil spill is on water a composition is provided which is particularly suitable for collecting the oil comprising the combination of a material that is at least temporarily buoyant and diatomaceous earth.  The resultant product from the method of collecting oil from oil spills on land may be used as a fuel. The same applies to the composition resulting from the collection of oil from oil spills on water where the buoyant material is combustible.

Abstract: ABSTRACT OF THE DISCLOSURE            Disclosed is a means for preventing "logging" of receivers, that is, the excess filling of a receiver with liquid in a refrigerator system of the type in which a compressor, a condensor, and one or more evaporators are connected in a closed cycle in association with a surge receiver.  Communication between the discharge side of the compressor and the receiver incorporates a valve of the differential pressure regulating type, having means sensitive to the relationship of pressures established and main-tained in a liquid line extending from the condenser to the evaporator and in the compressor discharge line extending from the compressor to the condenser, respectively.  The receiver valve responds to the pressure differential between these lines to maintain pressure in the receiver at a value slightly less than the maintained condensing pressure existing in the liquid line, to prevent excess liquid from accumulating in the receiver and in this way eliminate "starving" of the expansion valves associated with the evaporators.  The disclosed means for establishing and maintaining receiver pressure in a preferred embodiment utilizes a capillary sensing element in association with a receiver pressure regulating valve.  The element senses pressure in the liquid line upstream from an inlet pressure regulating valve.  The inlet pressure regulating valve establishes and maintains an optimum condensing pressure and as a consequence thereof establishes the desired optimum differential between the pressures at the inlet and outlet sides of the condenser.

Abstract: Abstract of the Disclosure A document feeder for advancing original document- to the imaging platen of an electrophotographic copier which is capable of operating in either a semiautomatic or fully auto-matic mode.  In the semiautomatic mode, an original to be copied is manually inserted face up into an inlet where it is engaged by the semiautomatic transport assembly, turned around and advanced to a proper position for copying.  After exposure the document is again turned around and guided into a receiving tray overlying the platen.  In the automatic mode of operation, a second tray normally maintained in a remote or inoperative position is swung down to a position at which its feed end is adjacent the feeder inlet.  Docu-ments to be copied are placed face up as a stack in the second tray, and feed rollers carried by the tray are actu-ated to advance documents individually from the top of the stack to the inlet.  A friction retarding roller engaging the bottom of the stack and the feed end is positively driven in a reverse direction to prevent the simultaneous feed of more than one document.  In an alternative embodiment, the feed roller is disposed below the retarding roller to feed sheets from the bottom of the stack so that the sheets are collected in the stacking tray in their original order.
