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: Abstract of the Disclosure The disclosure teaches a thin tin-plated steel sheet which includes a first layer of substantially uniform thickness of tin in an amount of 0.05 - 0.60 gram per square meter of the total surface area of the base, and a second layer of substantially uniform thickness consisting essentially of hydrated chromium oxide in an amount of 0.005 - 0.05 g/m2 calculated as chromium.  The first layer is disposed between the base and the second layer over substantially the entire total surface area of the base.  Any metallic chromium deposited between the first and second layers is present in an amount of less than 0.005 g/m2.  A process for produc-ing the sheet includes the steps of electrolytically tin plating a substantially clean steel sheet base in an electrolyte containing stannous sulfate, stannous chloride, stannous fluo-borate, sodium stannate or potassium stannate and then treating the plated sheet in an electrolyte containing chromic acid and one of sulphuric acid, a fluorene compound, an aromatic dis-ulfonic acid or thiourea.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for changing the rotation speed of a workpiece holder axle relative to the axle of a drive shaft, the tangential acceleration of this movement, and the pressure between the surface of workpieces and lapping tools.  These changes are set cyclically, directly in the apparatus for finishing.  The machines for the realization of such control of the finishing process are equipped with units which are capable of regulating the value of the complex eccentricity of holder rotation and have independent drive systems for adjusting the kinematic factors in the course of finish-ing.  This ensures uniform abrasion over the entire working surface of the lapping tools.

Abstract: ABSTRACT OF THE DISCLOSURE         A support member joined to a steering column to hold the column from below has planar opposite side portions formed in their rear ends closer to the steering handle with elongated grooves for passing bolts for anchoring the support member to the vehicle body.  A frame-shaped energy absorbing member having a deformation promoting aperture punched therein to form zigzag substantial portions in parallel to the axis of the column is provided between the support member and the vehicle body.  The absorbing member is partially formed with weak portions and is secured at its front end to the front portion of the support member and anchored to the vehicle body by the bolts.  When the absorbing member is subjected to load less than a specified value and acting axially of the column upon the displacement of the support member toward the steering gear in the event of collision of the vehicle, the absorbing member undergoes plastic deformation while if the load is greater, the absorbing member is breakable at the weak portions.  The absorbing member has curved projections producing a saturated spring action on the support member and on the vehicle body against the axial fastening force of the bolts, permitting the friction between the support member and the absorbing member also to absorb the energy of collision.

Abstract: ABSTRACT            A valve device for pressure-relief of, e.g., hydraulic props of mine equipment, has a main hollow housing into which a guide is in screw threaded engagement for adjustment purposes.  The guide has a through bore which slidably receives the cylindrical stem of a valve member.  The valve meter has a domed head with a stop face held against an inner end face of the guide by means of a compression spring located in the housing and hearing on a thrust bushing guided and located on the head of the valve member.  The stem of the valve member has a blind  axial bore leading to frusto-conical outlets at its periphery via radial borings.  The axial bore in the stem receives  pressure fluid to be controlled via the guide bore.  A sealing ring held in a groove in the guide bore engages on the periphery of the stem of the valve member.  As defined hereinafter, the material of the sealing ring has a certain composition and certain other characteristics  of the valve device components have a specific relationship to provide an improved performance.          Excess pressure moves the valve member to raise the head off the guide end face against the restoring force of the spring to thereby allow pressure fluid to discharge from the outlets of the valve member, moved beyond the sealing ring.
