Granted: 1981-11-03
Abstract: A B S T R A C T           Installation and method for the storage of thermal energy and its supply when required.  The thermal energy may be solar or be derived from industry.  For storage a pond is used which holds an aqueous saline solution whose concentration and temperature decreases from bottom to top and which is saturated at each level at the temperature there prevailing.  Solid solute is provided at the bottom of the pond.  Heat extraction is effected from solution at the bottom region and may be effected by heat exchange within the pond or by withdrawal of solution from near the bottom of the pond subjecting the withdrawn solution to heat exchange outside the pond and returning the solution and precipitated solute to the pond.

Title: Stops of a draft gear housing of a rail  car central coupler arranged in a center  sill
Inventor: ZEHNDER JUERG
IPC: B61G7/10
Filed: 1979-08-06
Granted: 1982-07-06
Abstract: ABSTRACT OF THE DISCLOSURE      The stops of a draft gear housing of a rail car central coupler have to meet relatively large tractive and compressive forces in service.  Up to now the expense involved in the fastening of such stops has been very great.  In many cases, where the stops or bearings were joined to the center or stub sill, cracks formed and/or the sill became deformed.  This incurs considerable expense for repairs and means a loss of service while the vehicle is being repaired.  In accordance with the instant disclosure, to avoid such problems the center or stub sill of the rail car is now made such that the front stop and the rear stop are integral parts of the sill.

Title: Frame construction for making round comb  honey
Inventor: ROSS THOMAS B
IPC: A01K47/02
Filed: 1979-08-23
Granted: 1981-11-24
Abstract: ABSTRACT OF THE DISCLOSURE           An improved frame section which is adapted to be mounted in a beehive in abutting relationship with a plurality of similar frame sections for making round comb honey.  A plur-ality of circular openings are formed by cylindrical walls in each of the frame sections.  A plurality of cylindrically shaped, horizontally extending chambers or "rounds" are formed by abut-ting pairs of the cylindrical walls of adjacent frame sections. The cylindrical frame walls each have a pair of arcuate zones of reduced axial lengths with respect to a second pair of inter-vening arcuate zones of greater axial lengths.  The smaller axial length zones form a series of top and bottom openings along the frames when assembled, to provide access openings for the bees to the interior chambers.  A ring is telescopically seated within each of the frame openings to form the sidewall of a container for the formed combs.  The ring has two pairs of inter-vening, diametrically opposed arcuate zones of shorter and longer axial lengths which are adapted to coincide with the correspond-ing shorter and longer axial length zones of the cylindrical frame wall.  Projections are formed on the ends of each of the cylindrical wall zones of greater axial length adjacent the intervening wall zones of shorter axial lengths to provide a seat for the ring.  One of the frame wall zones of the pair which have the greater axial lengths has a greater arcuate length than the other wall zones of that pair whereby the intervening wall zones are not diametrically opposite of each other, thereby preventing the insert ring from being installed incorrectly. The rings and frame are formed of contrasting colors to provide a visual check as to the placement of a ring in each of the frame openings.

Abstract: A B S T R A C T            IMPROVED LONGITUDINAL BALANCE ARRANGEMENTS FOR TWO-TO-FOUR TELECOMMUNICATION LINE CIRCUITS      A conventional interface for 2-wire telephone lines to a digital switch includes line current feed resistors and a bridge circuit where the line impedance is compared with a compromise balance network.  The accuracy of the balance determines the proportion of the signal received on the receive pair being retransmitted in the transmit direction.  The ratio of these signals is known as the Trans-Hybrid loss and should be as high as possible for good quality speech.      In practice the telephone line impedance increases with length as also does the DC resistance of the line and thus the line current, assuming a constant voltage source.      It is proposed that the line current feed resistors be formed on a common substrate using well-established film deposition techniques and the balance resistor be formed on the same substrate using a material having a negative temperature coefficient.  Thus on short lines the dissipation in the line feed resistors is high, raising the temperature of the substrate, thus reducing the value of the balance resistor and hence improving the balance.

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.
