Abstract: ABSTRACT OF THE DISCLOSURE      A method for pneumatically transferring particulate solid materials into an earth formation penetrated by a well bore is shown.  A gas is flowed into the well bore to establish the desired injection rate and pressure.  A particulate  solid  material  is  then  added  to  the established  gas  flow  passing  into  the  well  bore  by flowing a spas containing an entrained particulate solid material  into  the  established  gas  flow  to  thereby transfer  the  solid  particulate  material  pneumatically into the well bore.

Suitable salts of formula II include diphenyliodosyl hexafluorophosphate and tetrafluoroborate.  The compositions may be photopolymerised or they may be thermally polimerised in the presence, as catalyst for the iodosyl salt, of a salt or complex of a d-block transition metal, a stannous salt, an organic peroxide or an activated .alpha.-hydroxy compound.     The compositions may be used as surface coatings and adhesives, and in the preparation of printing plates, printed circuits and reinforced composites.

Abstract: Abstract A borehole survey instrument has a probe with a polarized light system for transmitting a signal representing the angular orientation of the probe to the surface. Light from a source in the probe is directed through a polarizing filter with an axis of polarization orthogonal to the longitudinal axis of the probe. The polarized light beam is transmitted to the surface through an optical fiber light conduit. The angle of polarization is detected with a rotating polarizing filter and provides a measure of the probe orientation. In surveying a borehole, azimuth is determined from inclinometer measurements. The probe orientation in vertical sections of the borehole is measured by the polarized light system. Two measures of borehole azimuth are combined, providing an improved measure of azimuth an boreholes near vertical and near horizontal.

Abstract: ABSTRACT      A method is disclosed for the production of mould parts by an automatic mould part producing apparatus which comprises a mould chamber having pressure plates moveable towards one another and mould plates fastened to the pressure plates and a container for holding a supply of mould material.  The container is disposed above the mould chamber and communicates therewith via a funnel-shaped inlet wherein a pressurized gas is introduced into the container above the supply of material for inserting the material via the funnel-shaped inlet into the mould chamber.  Further pressurized gas is used to fluidise the material in the throat region of the funnel-shaped inlet and the method is characterized by the further steps of continuously adjusting the pressure of the pressurized gas above the supply of material in dependence on the form of the mould part being produced and of continuously and independently adjusting the pressure of the gas used to fluidise the material in the throat region of the funnel-shaped inlet in dependence on the form of the mould part being produced.

Abstract: LAMP FIXTURE FOR ILLUMINATING INTERIOR OF               CIGAR LIGHTER SOCKET                     Abstract A one-piece molded plastic lamp fixture for mount-ing a light bulb at the exterior of the clamping shell portion of an electric cigar lighter for vehicles, to provide illumination of the socket thereof. The clamping shell has a light-admitting aperture over which the bulb is positioned when carried in a body part of the plastic fixture. An integral plastic hood is connected to the body part adjacent the bulb, and can be swung from a first position overlying and generally concealing the bulb, to a second position wherein the bulb is exposed for replacement. The body and hood portions are joined by a living hinge, and the body portion is held on the clamping shell by resilient, opposed integral retainer fingers that are receivable in openings in the shell.          The hood portion has integral ears which underlie and back up the retainer fingers when the hood is swung to its first position whereby inward movement of the fin-gers is limited to prevent the fixture from becoming inadvertently loosened from the clamping shell. The ad-vantage of the present invention over the devices of the prior art is that less manufacturing and assembly ex-pense is required, since the hood and body portions, and hinge can all be molded as a single integral plastic or nylon piece.

Abstract: CHELATORS WHOSE AFFINITY FOR CALCIUM     IS DECREASED BY ILLUMINATION           ABSTRACT         The present invention discloses a group of calcium chelating compounds which have a decreased affinity for calcium following illumination.  These new compounds contain a photolabile nitrobenzyl derivative coupled to a tetracarboxylate Ca2+ chelating parent compound having the octacoordinate chelating groups characteristic of EGTA or BAPTA.  In a first form, the new compounds are comprised of a BAPTA-like chelator coupled to a single 2-nitrobenzyl derivative, which in turn is a photochemical precursor of a 2-nitrosobenzophenone.  In a second form, the new compounds are comprised of a BAPTA-like chelator coupled to two 2-nitrobenzyl derivatives, themselves photochemical precursors of the related 2-nitrosobenzophenones.         The present invention also discloses a novel method for preparing 1-hydroxy- or 1-alkoxy-1-(2-nitroaryl)-1-aryl methanes.  Methanes of this type are critical to the preparation of, or actually constitute, the photolabile Ca2+ chelating compounds disclosed and claimed herein.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a method of increasing the operating cell voltage of a solid oxide electrochemical cell having metal   electrode   particles   in   contact   with   an oxygen-transporting ceramic electrolyte.  The metal elec-trode is heated with the cell, and oxygen is passed through the oxygen-transporting ceramic electrolyte to the surface of the metal electrode particles so that the metal elec-trode particles are oxidized to form a metal oxide layer between the metal electrode particles and the electrolyte. The metal oxide layer is then reduced to form porous metal between  the  metal  electrode  particles  and  the  ceramic electrolyte.

The reflector is made of aluminum or an aluminum alloy.  Owing to the provision of the color-compensating anodic oxidation coating, the reflectivity of the reflector to light in a wavelength region corresponding to the oversensitive range of the photosensitive member is smaller than its reflectivity to light in wavelength region other than the first-mentioned wavelength region.
