Abstract: "SELF-CONTAINING PACKAGE SYSTEM FOR STORAGE  AND TRANSPORTATION OF PRE-FABRICATED PORTIONS OF A BUILDING STRUCTURE AND THE ASSEMBLY THEREOF     ABSTRACT OF THE DISCLOSURE           A floor or ceiling unit is prefabricated in two halves which can be assembled together to form the unit or one of the halves can be turned upsidedown and nested underneath the other half thus forming a package with upper and lower panels.   These panels can be secured together and reduce the overall width of the package to a dimension which is smaller than the maximum allowable width for transportation on world roads.         Also included are vertical support members and the pair of perimetrical beams which extend between the vertical support members and means on the beams and sup-port members to receive and support the assembled floor or ceiling unit.   The vertical support members and the perimetrical beams can be stored between the joists of the two halves when they are packaged for transportation and a plurality of such packages can be stacked one upon the other upon a truck or the  like thus enabling an entire building to be transported readily and easily and within allowable size limits and which can be readily erected on site with the minimum of effort.

Abstract: SELF-TUNING REGULATOR IMPLEMENT CONTROL       Abstract of the Disclosure A hitch control system generates a rockshaft valve control signal as a function of sensed draft force, rockshaft position and operator input.  Periodically, an auxiliary or disturbance signal of certain amplitude, frequency and duration is superimposed on the valve command signal.  A calculated soil/implement gain is derived from components of the valve command signal and the measured draft force which have certain phase relationships with the disturbance signal.  An electronic gain is modified so that the overall soil/implement gain remains substantially constant.

Abstract: PULSED LIGHT SELECTIVE PHOTOLYSIS PROCESS     FOR TREATMENT OF BIOLOGICAL MEDIA     AND PRODUCTS MADE THEREBY     ABSTRACT     A novel irradiation process and products made thereby.  the process treats biological media such as blood factions, genetically engineered protein products and vaccine preparations.  The process photolyzes nucleic acids in preference to proteins in the media, e.g., it inactivates DNA-or RNA-containing pathogens while leaving the proteins substantially intact or functional.  In general, the process comprises irradiating the medium with pulsed light of wavelength and flux selected so that (1) the nucleic acids in their ground state absorb radiation and thereby rise to an excited state or states, (2) the nucleic acids in their excited states absorb radiation and thereby rise to higher energy states and undergo photolysis, and (3) the proteins in their ground or their excited states do not absorb sufficient radiation to undergo substantial photolysis.  It is surprising and unexpected that nucleic acids in their excited states undergo efficient photolysis whereas proteins under the same conditions in the same medium are kept substantially intact.

The outputs from the elements in a transducer array are each divided into two components whose amplitudes are respectively proportional to the sine and cosine of the required phase shift, which are then processed so that the steered beam may be formed by coherent summation.  The proportionalities of the respective sine and cosine components are achieved by switched capacitor circuits, which are preferably implemented by LSI circuits, permitting substantial hardware savings and yielding highly accurate component proportionalities.

Abstract: ABSTRACT          A slow blow fuse of the shunt type includes a pair of spaced terminals between which is connected and suspended a fuse wire assembly including a core of insulating material having at least a pair of fuse filaments upon the same, the outer of which is preferably an untinned spirally wound filament wrapped a number of times around one and more preferably at least two straight filaments, only one of which is tin plated, extending axially along the core.  The uncoated spirally wound filament thus makes repeated physical and axial spaced electrical contact with the tinned filament.  There are thus at least two fuse filaments in electrical parallel relation at a number of different locations therealong, each sharing a layer of tin coating.  Each of the fuse filaments comprises a body of base metal which will melt instantly under short circuit current and is to melt under prolonged modest overload currents when the melting temperature lowering tinning material progressively migrates fully into the base metal body of the fuse filaments.

In response to the solicit message, each of the prescribed server computers determines if it is available as a resource to the client computer.  The server then transmits a positive response message or a negative response message to the client computer if the server computer is available or unavailable, respectively.          In addition, when a server computer becomes available as a resource to one or more client computers, it transmits an advertisement message to the prospective client or clients.

Granted: 1989-09-26
Abstract: GUTTER CLEANING TOOL                   Abstract of the Disclosure The tool of the present invention is comprised of a scoop having flexible side walls which, at the mouth of the scoop, normally are wider and higher than the gut-ter into which the tool is to be inserted.  The side walls become progressively narrower extending away from the mouth of the scoop and terminate in a heel at the closed end of the scoop which is considerably narrower than its mouth.  In addition, the heel is relatively inflexible thereby allowing it to be inserted into a gutter which is much smaller than the remainder of the scoop.  Once the heel is in place the remainder of the scoop can be in-serted into the gutter by rotating the scoop downwardly while drawing the tool backwardly along the length of the gutter.  Once in place the flexible side walls will con-form to the shape of the gutter thereby completely filling the gutter.  After the tool is inserted the gutter is cleaned by sliding the tool along the gutter until it is full.  A handle located above and behind the heel of the scoop assists the user in inserting the tool and in moving it to clean the gutter.  A low-walled tongue located at the front of the scoop, in front of the mouth, facilitates removing debris from beneath the spikes which attach the gutter to the roof.
