Abstract: ABSTRACT OF THE DISCLOSURE           The  specification discloses a hydrometallurgical process for the selective dissolution of mixtures of metallic oxy compounds.  It relates particularly to the selective putting into solution of certain non-ferrous metals present in these mixtures.  In order to extract the metal or metals, it is necessary to separate one from the other and, in particular to separate iron which is very often present in minerals of non-ferrous metals and which is then found in variable proportions in the first stages of the purification of these metals.  This specification discloses a process for the selective dissolution of oxides of non-ferrous metals which permits their separation from iron, manganese and silica.  Thus this specification discloses a process for the selective dissolution of oxygen-containing metallic compounds, characterised by the fact that it comprises the following successive steps: a)  The mixture of compounds is put into suspension in an aqueous phase and b)  the suspension is treated with chlorine, the pH of the suspension being kept at a value above 2, or preferably above 3, whereby any iron, manganese, silica and cobalt remain undissolved in the suspension.

Abstract: RCA 70,954 PLANAR PRINTED CIRCUIT BOARD ARRANGEMENT USEFUL IN THE UHF PORTION OF A TELEVISION TUNER             Abstract of the Disclosure A tuner for a television receiver comprises a circuit board formed by a slab of dielectric material having conductors located on one side and discrete components mounted on the other so that it may be readily assembled and soldered.  Some of the conductors are arranged to form capacitors and distributed parameter inductors.  In the UHF portion of the tuner a strip-like conductor and a wider ground conductor are spaced apart in parallel relationship.          The length of the gap between the strip-like conductor and the ground conductor is selected to provide inductive react-ance in the UHF band.  A slot is cut, punched or otherwise formed through the dielectric material in the gap between the strip-like conductor and the ground conductor to increase the Q (the figure of merit inversely related to loss) of the inductor at the upper end of the UHF range.  In addition, the slot significantly improves thermal stability of the inductor.          Furthermore, the combination of the slot associated with the inductor and another slot utilized to mount a varactor diode, coupled to the inductor to form a tuned circuit, determines the length of the gap.  In a preferred arrangement, the two slots are punched by a unitary die to minimize the variation of inductance values from one tuner to another due to regis-tration errors.

Title: Method and apparatus for drilling a hole in a body of ice and for the destruction of a body of ice

Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for drilling a hole in a body of ice and for destroying a body of ice.  The method comprises the steps of providing a source of reactant gas of a type which will react chemically with ice to form solid compounds which are unstable and which break down rapidly to water and a dissolved gas.  The reaction product which is formed is removed quickly in order to avoid a secondary and initially undesirable exothermic reaction of gas dissolution into the water so formed.  The reactant gas is directed through a nozzle to generate a stream of reactant gas.  The nozzle is located in close proximity to a body of ice, and the stream of reactant gas is directed against a localized area of the surface of said body of ice at a velocity and flow rate to obtain an optimum phase change reaction with the ice and to quickly remove water formed from the ice in the localized area.  The nozzle is advanced towards the body of ice to continue to direct the stream of reactant gas against the receding surface of the body of ice in the localized area as the ice undergoes a phase change to the liquid state to destroy the body of ice or to form a hole in the localized area in the body of ice.

Abstract: TITLE    :   METHOD AND APPARATUS FOR FORMING A  NARROW WEAVE FROM BARE ELASTOMERIC THREADS          INVENTOR :   Thomas C. Black ABSTRACT OF THE DISCLOSURE:         A narrow woven stretch fabric is formed from bare elastomeric warp threads separated by high shrink warp threads and from a high shrink weft thread.  The edge elastomeric warp threads are loosely wrapped with heat set yarn.  These edge threads, which are under the same tension as the other elasto-meric warp threads, are wrapped between the supply and the loom.          The weft thread is interwoven at a low weft per inch and the fabric is heat treated to shrink the non-elastic high shrink threads and corrugate the elastomeric threads without heat setting.  The wrapping device and the surface feed rollers for the elastomeric threads are driven by the loom drive at appropriate speeds.

Abstract: APPARATUS FOR MEASURING THE ALCOHOL PERCENTAGE          IN THE BREATH OF AN EXAMINEE.             Abstract of the disclosure Apparatus for measuring the alcohol percentage in the breath of a person by blowing the breath into an airtight chamber enclosing a gas detector of the type of which the electric resistance changes upon exposure to alcohol vapor. The breath is introduced into the chamber in such manner that it does not directly strike the gas detector, so that a cooling of the gas detector by the air flow is avoided. Thus, the resistance change of the gas detector is substantially exclusively dependent on the alcohol percentage in the breath, whereby a very accurate measurement is obtained.

Abstract: ABSTRACT A tree felling head having an accumulator for accumulating trees in an area offset from an area wherein the trees are severed by shear means from their stump.  A sweep arm is swingably mounted on the felling head for moving the trees in succession as they are cut into the collecting or accumulating area and the trees are received therein and retained in the area by an accumulating arm means.  The accumulating arm means is an articulated member consisting of a first arm pivotally attached to the frame and having a second arm or finger member pivotally attached to the free end thereof.  A hydraulic cylinder actuates the two pivotally mounted arms of the accumulator, with the finger being actuated by way of a link that is pivotally attached at one end to a lug member freely pivotable on the pin mounting the other arm on the frame.  Three separate hydraulic power cylinder units are utilized for respectively moving the shear jaw, the sweep arm and the accumulating arm means.  The three cylinders are located vertically one above the other in overlapping relationship in three different horizontal planes, thus minimizing the overall width of the felling head and disposing the hydraulic cylinders in an area where they are protected from possible damage during use of the felling head.
