Abstract: ABSTRACT         A gaseous laser medium is photodissociated into an upper laser state by vacuum ultraviolet light from an electri-cally excited noble gas mixed with the laser medium.  A gas-eous laser medium, such as cyanogen bromide, is preferably res-onantly excited by photodissociation by such vacuum ultraviolet light.  CN particles in the B state undergo laser transition to the X state, producing radiation at about 4000.ANG..  Alterna-tively or additionally, a gaseous laser medium is excited to produce molecules, such as halogen molecules, particularly Br2, in an upper laser state whence they undergo transition by laser action to a weakly bound lower laser state that is rapidly de-populated.

Abstract: ABSTRACT OF THE DISCLOSURE         High impact mineral filled polycarbonates are comprised of a polycarbonate resin of a novaculite mineral filler having an average particle size of less than 5 microns.  The percentage of novaculite is based on the total weight of the polycarbonate resin and novaculite. The polycarbonate articles formed from the mineral filled blends exhibit excellent impact properties over typical fillers for polycarbonate resin.  Impact properties of the polycarbonate can be further improved by the addition of a silane coupling agent to the polycarbonate novaculite blend.

Abstract: Abstract of the Disclosure The esterification of carboxylic acids with .beta.-silyl-ethyl alcohols of the formula                       [(I)-OH], in which each of R1, R2 and R3 independently represents a hydrocarbon radical and the individual radicals can be linked a single C-C bond,gives corresponding novel esters, the .beta.-silylethyl ester group of which can be split off, with liberation of the carboxyl group, by treatment with a salt of hydrofluoric acid, especially a fluoride of a quaternary organic base.     Sincc these conditions are very mild and specific, ester groups of this type are suitable as carboxyl protective groups, especially in polyfunctional compounds, such as steroids, prostaglandines, .beta.-lactam compounds and, above all, aminoacids  and peptides, in which the other func-tional groups, including other carboxyl groups, can be protec-ted in a conventional manner.

Abstract: ABSTRACT         An air conditioning apparatus and method are disclosed.          The apparatus includes a chemical dehumidifier which employs an aqueous hygroscopic solution of glycol and a solar energy collector for use in regenerating the solution.  Air to be conditioned is circulated through a contactor of the chemical dehumidifier, in contact with cooled glycol solution.          Concentrated hygroscopic glycol solution is circulated from a regenerator to the contactor, while dilute solution is circulated from the contactor to the regenerator.  Energy from the solar collector is transferred to facilitate concentration thereof.  In one disclosed embodiment energy from the solar collector is also transferred to the generator of heat-powered refrigeration apparatus, e.g., absorption or rankine engine driven refrigeration apparatus.  The condenser of the refrigeration apparatus may operate to heat the glycol solution in the regenerator of the dehumidifier and the evaporator may cool the concentrated glycol solution in the contactor and/or may supply chilled fluid to a heat exchanger for cooling the dehumidified air.  In a modified embodiment, a diesel engine drives the refrigeration apparatus.  Waste heat from the diesel engine either augments the solar energy for regenerating the glycol solution or regenerates desiccant from a second stage of dehumidification.

Abstract: METHOD FOR JOINING FIBERGLASS PLASTIC ROD TO METAL FITTING OF ELECTRICAL               ABSTRACT OF THE DISCLOSURE       According to the method for joining a fiberglass plas-tic rod to a metal fitting of an electrical device, a hole is first provided in the metal fitting, the diameter of said hole being somewhat greater than that of the fiberglass plas-tic rod. One of the rod's ends is then installed in the hole, and the gap between the metal fitting and fiberglass plastic rod is filled with a porous material. The whole is then com-pressed by using the pulse loading technique. The use of pulse loading for joining the fiberglass plastic rod to the metal fitting makes it possible to develop a high pressure in the zone of the joint without destroying the rod; this task is facilitated by the presence of the porous layer between the rod and metal fitting Compression by pulse loading does not necessitate the use of expensive equipment, nor does it impose stringent accuracy requirements upon the elements to be joined. The method according to the invention accounts for a desired distribution of pressure over the inbuilt end of the fiber-glass plastic rod.

Abstract: METHOD OF THERMAL-MINE RECOVERY OF OIL AND FLUENT  BITUMENS           ABSTRACT OF THE DISCLOSURE    The method of thermal-mine recovery of oil and fluent bitumens or kerogens includes providing a system of mine workings above an oil-bearing formation and drilling from these workings and from the ground surface a series of injecti-on wells into the oil-bearing formation. An operation gallery is provided within the oil-bearing formation, from which a system of horizontal and inclined recovery wells is drilled. Then a heat carrier is positively injected into the oil-bearing formation to heat it to a temperature whereat the oil attains the required fluidity within the formation. Then a fluid is charged into the formation to force the oil from the oil-bearing formation into the horizontal and inclined recovery wells, toward the operation gallery, from which the oil is directed to the ground surface. The improvement of the method resides in that the heat carrier is injected into the formation through the horizontal and inclined recovery wells extending substantially across the predominant direction of the highly permeable zones of the oil-bearing formation, and, following the heating of the formation to the above said temperature, the injection of the heat carrier is terminated, and the fluid is charged into the injection wells having minimized association with the highly permeable zones of the oil-bearing formation, to force the oil from the oil-bearing formation through the recovery wells toward the recovery gallery.
