Abstract: PHOTON ENERGY CONVERTER                Abstract of the Disclosure An efficient converter of photon energy to heat has been devised comprising a dense array of metal whiskers grown with spacings between the whiskers of a few wavelengths of visible light.  The material selected, and tungsten is exemplary of such materials, has low emissivity, but achieves significant optical absorption by trapping the light impinging on the dense array by a geometric maze effect.  The characteristics of the sur-face are excellent for the conversion of solar energy to heat.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to an improved method for the preparation of fuel rods for a high temperature, gas-cooled reactor.  By carbon-izing the fuel rods in a pressurized autoclave which maintains a compressive stress on the fuel particles until the matrix strength is reduced, a reduction in the degree of internal stress occurs in the body of the fuel rods resulting in a reduced incidence of rupture of the pyrolytic-carbon coatings on each fuel microsphere.  In addition, the pitch coke yield of the fuel rods obtained by the present method is about three times that normally obtained in rods carbonized in packed Al2O3 powder, and about 1-1/2 to 2 times that obtained when carbon-izing in graphite tubes at atmospheric pressure.

Abstract: ABSTRACT OF THE DISCLOSURE:          The invention is concerned with a  process for producing weighting materials for drilling fluids, in which solids consisting mainly of iron oxide are fired at temperatures above 1200°C in an oxidizing atmosphere and subsequently cooled. According to the invention, the solids are fired at a temperature of 1210° to 1400°C under an oxidizing atmosphere having an oxygen partial pressure in excess of the equilibrium oxygen partial pressure of the iron oxide at the firing temperature . The solids are then cooled slowly to 780°C also in an oxidizing atmosphere. The so obtained weighting materials have an extremely low magnetic susceptibility and thus can be used without interfering with the inductive monitoring of the position of the drilling fluids.

Abstract: POWER PLANT AND SYSTEM FOR ACCELERATING A   CROSS COMPOUND TURBINE IN SUCH PLANT, ESPECIALLY ONE HAVING AN HTGR STEAM SUPPLY    ABSTRACT OF THE DISCLOSURE           An electric power plant having a cross compound steam turbine and a steam source that includes a high temperature gas-cooled nuclear reactor.  The steam turbine includes high and intermediate-pressure portions which drive a first generating means, and a low-pressure portion which drives a second generating means.  The steam source supplies superheat steam to the high-pressure turbine cportion, and an associated bypass permits the superheat steam to flow from the source to the exhaust of the high-pressure portion.  The intermediate and low-pressure portions use reheat steam; an associated bypass permits reheat steam to flow from the source to the low-pressure exhaust.  An auxiliary turbine driven by steam exhausted from the high-pressure portion and its bypass drives a gas blower to propel the coolant gas through the reactor.  While the bypass flow of reheat steam is varied to maintain an elevated pressure of reheat steam upon its discharge from the source, both the first and second generating means and their associated turbines are accelerated initially by admitting steam to the intermediate and low-pressure portions.  The electrical speed of the second generating means is equalized with that of the first generating means, whereupon the generating means are connected and accelerat-ion proceeds under control of the flow through the high-pressure portion.

Abstract: ABSTRACT         A flexible offset printing plate is formed from a directly imaged electrophotographic member comprising an inorganic coating of a photoconductive material on a polymer substrata.  The photoconductive material is an oriented crystalline deposit about 3000 Angstroms thick which has been directly sputtered with radiofrequency energy in a process using a Langmuir sheath to produce a light sensitive, readily imaged abrasion-resistant, transparent coating.  It is deposited on a sheet of dimensionally stable, transparent polyester film having thickness of about .005 inch with an intervening sandwiched layer of ohmic material such as indiumtin oxide about 300 Angstroms thick.  The transparency of the ohmic layer and the photoconductive coating on a transparent substrate result in a transparent plate.         The electrophotographic member is imaged by charging, exposure and toning with a suitable toner.     The non-imaged parts of the surface are rendered hydro-philic (having a strong affinity for water and repellant to greasy ink) by treating the surface with one of the group a silicate polymer, a sodium aluminum hydroxide, a ferrocyanide reacted etch solution and a polyvinyl alcohol rendered insoluble in water while the imaged and toned parts are renderred hydrophobic (water-repellant and having a strong affinity for greasy ink), the treatment maintaining the other physical characteristics of the photoconductive coating unchanged.

Abstract: Abstract of the Disclosure A connecting element is disclosed which is used, when manufacturing wall- or ceiling-claddings by the so-called dry construction method, with the assembly of the abutting end-faces of preferably elongated cladding panels having the same width and consisting of wood and/or a plastic material and which are assembled by connecting the region of their longitudinal edges through a tongue-and-groove system.  The connecting element consists of a sectioned member whose longitudinal median plane preferably extends across that of the assembled panels and which comprises two locating strips contained at least approximately in the same plane and serving as a support for the undersides of the end face sections of two adjacent panels which are assembled end to end.  The locating strips are separated from one another by a locating wall for the end faces of the assembled panels and constitute for example part of a gap-forming flange with an essentially rectangular cross-section which determines the width of the joint gap, projecting approximately at right angles from the plane of the locating strips.  Preferably either end of the locating strips is associated with a clamping plate capable of establishing a clamped connection between the sectioned member and one of the assembled panels, the spacing between the clamping plate and the corresponding locating strip being approximately equal to the distance between the locating strip and the longitudinal groove in the panel.  At least two lateral stops are provided for each locating strip in the direction across the longitudinal axis, the spacing between the stops corresponding either to the distance between the two longitudinal side edges of the corresponding panel or to the distance between the ground-surfaces of the longitudinal grooves which take part in the connection between a given panel and the adjacent panels at either of its longitudinal sides.
