Abstract: ABSTRACT       EPOXY RESIN GEL TESTER            A method of and apparatus for determining the gel point of a sample of epoxy resin.  The sample is prepared by grinding it into a fine powder and placing it into a sample tube of aluminum foil.  The prepared sample is inserted into the test pressure sensor which is located within a preheated laboratory environmental chamber.  The test pressure sensor consists of two knurled cylinders each rotatably mounted about its axis wherein the axes are parallel and the plane of the two axes is horizontal.  The two knurled cylinders are slowly rotated by a small electric motor such that when viewed in a direction parallel to their axes, the cylin-der on the left rotates in a clockwise direction and the cylinder on the right rotates in a counterclockwise direction.  The axis of one of the cylinders is fixedly mounted.  The axis of the other cylinder is slidably mounted within the horizontal plane of the two axes. A spring tends to force the axis of the slidably mounted cylinder toward the axis of the fixedly mounted cylinder. A set of electric contacts can measure when the two cylinders are within or without a given distance.  The prepared sample becomes liquid within the aluminum foil sample tube, and the two are drawn into the nip of the cylinders by their rotation.  The cylinders continue to rotate slowly, collapsing the sample tube within the nip of the cylinders causing the liquid resin to be displaced above the nip of the cylinders within the sample tube. When the prepared sample becomes a plastic wedge, signi-fying the gel point, it is drawn into the nip of the cylinders forcing them sufficiently apart to be measured by the set of electric contacts.  A timer records the number of seconds between the insertion of the sample and the gel point.

Abstract: ABSTRACT OF THE DISCLOSURE          A lightweight concrete float having a concrete shell surrounding either a hollow or buoyant foam core.  The shell includes a deck surrounded by integrally formed, down-wardly projecting side walls of sturdy but relatively heavy standard aggregate concrete and a bottom surrounded by inte-grally formed, upwardly projecting uniform or tapered side walls of lightweight but relatively weak foam aggregate con-crete.  Reinforcing rods are embedded along the edges of the deck, and a reinforcing mesh extends around the reinforcing rods and through the deck, side walls and bottom.  The float may be formed by first pouring a layer of foam aggregate con-crete into a form having a rectangular bottom surrounded by four sides.  A block of buoyant foam is then placed on the bottom layer of concrete with the sides of the block spaced apart from the sides of the form.  The space between the sides of the form and the sides of the block is partially filled with foam aggregate concrete. Standard aggregate con-crete is then poured into the form in order to fill the re-maining space between the sides of the form and the sides of the block and to cover the upper surface of the block. Vibra-tion of t?   interface between the foam aggregate concrete and the standard aggregate concrete ensures firm bonding between the two concrete varieties.

Abstract: ECONOMIC SOLAR ENERGY CONCENTRATION AND COLLECTION                Abstract of the Disclosure Apparatus and methods for concentrating and collect-ing solar energy are disclosed.  In accordance with the in-vention, solar energy is concentrated by economical refringent lenses or lens systems including fluid lenses and/or Fresnel-type lenses.  The lenses concentrate the solar energy pre-ferably along lines in continuous linear foci or in discrete foci at an elongated collector comprising one or more fluid-carrying conduits and one or more fluids therein.  In one embodiment, a plurality of photoelectric  cells are located in or on the collector along the linear foci or at the discrete foci and operate at increased efficiency with heat being removed by the collector.  A first fluid in the collector is heated by the concentrated solar energy and in a preferred embodiment is used to heat a second fluid contiguous to the first fluid, the first fluid having a boiling point exceed-ing that of the second fluid. In a preferred embodiment, the first fluid is carried in an inner conduit while the second fluid is carried by an outer conduit which encloses the inner conduit and first fluid.  Thus, the two fluids can be heated to different temperatures by a single concentrating system and used for different purposes.  Additionally, the invention provides for the storage of energy using two fluids of different boiling points.  Also disclosed are methods and fixed and portable apparatus for distilling water containing salt or other substances by evaporation of the water and con-densation of the water vapor wherein preferably the heat of condensation is recovered.  The invention also provides for assemblies of individual systems to form larger systems. The present invention provides heat from solar energy at a cost competitive with heat produced from fuels.

Abstract: A B S T R A C T     DIGITALLY CONTROLLED WIDE RANGE     AUTOMATIC GAIN CONTROL            In high speed high quality modems it is important to be able to preserve the gain value for the automatic gain control, system during breaks in transmission to permit rapid resumption of normal operation.  The a.g.c. circuit comprises a basic a.g.c. transistor amplifier whose emitter-collector conductance is varied by a control voltage derived from the envelope of the amplifier output voltage which is well known.  A digital-to-analog converter is used which is controlled by a digital-up-down counter.  The counter is controlled by a window com-parator which compares the rectified output voltage of the amplifier with a reference voltage level and upper and lower limits.  If the output voltage exceeds either limit, the counter is enabled and the appropriate up or down indication is given.          The counter is then clocked to change the drive to the d-to-a converter which thereby changes the conductance of the a.g.c. transistor.  The state of the up down counter will be used to maintain the a.g.c. at the last level in the event of a transmission break by inhibiting the clock for the counter.

Abstract: ABSTRACT              Underwater Seismic Testing The invention provides a sound source for use in underwater seismic testing, the source comprising a substantially linear array of a predetermined number of air guns of differing volumes.  The spacing between the guns is determined by a "weighted centroid  distribution", this being determined by selecting a predetermined mathematical window function which is positive at all points within the window and which approximates to the Fourier transform of a single square wave, the width of the window being selected to correspond to the desired length of the array, and then dividing the area under the curve into areas which are the same in number as the air guns, and the relative proportion between the areas under the curve being the same as the relative effective weights of the individual air guns in the array.  The centroid of each such area is then determined, and the positioning of the air guns is proportional to the separation of the centroids measured on the x-axis of the function.  The mathematical window function may be a Hanning or a sinc function, for example.  The effective weights (i.e.the primary pressure amplitude responses) of the air guns preferably increase symmetrically from the ends of the array towards the mid-point thereof.

Abstract: Abstract:           An acrylic cement-like substance which permits seating and securing of a prosthesis into living bone which comprise  a mixture of a liquid monomer component and a polymer powder component such that upon mixing the two components,  a cement which maintains a low viscosity for a longer period of time is formed.   The low viscosity bone cement is intended for syringe or injector gun use only as it is to be used before the cement becomes doughy. This low viscosity bone cement has a viscosity at approximately 20 degrees C (68 degrees F), of less than 1500 poise, and preferably less than 1000 poise up to the sixth or seventh minute after the two components are mixed.  The cement used in the lower viscosity state is more capable of penetrating the trabeculae of bones when used to secure a prosthesis, than when the cement is applied in the doughy state.
