Abstract: Abstract A device for oral administration to a ruminant animal includes a veterinary medicament, such as an anthelmintic, uniformly dispersed throughout an erodable sheet comprising an ethylene-vinylacetate copolymer.  The sheet is rolled up and stuck together with adhesive backed paper strips for administration, and unrolls in the rumen to take up a planar configuration which is retained in the rumen.  The sheet may be placed within a plastics netting envelope to give more controlled erosion and release of medicament.

Abstract: ABSTRACT In the electrodeposition of metals in electrowinning and electro-refining processes, the current between end electrodes in a cell is generally higher than the average current between all electrodes in the cell thereby causing warping of the end electrodes, overheating of the electrical contacts at the end electrodes and a majority of the electrical shorts to occur at these end electrodes.  These problems are alleviated by controlling the current between the first two and between the last two electrodes at a value that is not greater than the average value of the current between all electrodes in the cell, by increasing the lateral spacing between the end electrodes and their immediate neighbouring electrodes.

Abstract: Abstract of the Disclosure This invention relates to lithographic patterning, particularly in  fabrication of integrated circuitry, which is based on the photoinduced migration of silver into germanium selenide or other glassy material of appropriate absorption cross section for a chosen actinic radiation.  Resists which are negative-acting yield ? resolution attributed to initial introduction of the silver in chemically combined form chosen so as to result in formation of a silver compound w? a glass component with the compound serving as silver source.  Removal of excess silver-containing material is engineered on the basis of the form of silver introduction and results in conversion to a water soluble form.  The developed, patterned resist may he used as a mask in a subsequent treatment of exposed portions of an underlying surface, such as etching, metallization, etc.  An embodiment in which the now developed patterned resist serves as a dry etching mask during delineation of a relatively thick underlying layer of organic material is also commercially feasible. This procedure is particularly advantageous for use on partially processed circuitry in which prior operations have resulted in surface steps.

Abstract: ABSTRACT OF THE DISCLOSURE         In drawing glass fiber from a glass melting furnace to form a multiplicity of filaments which are first divided and formed into a plurality of strands which are then wound on a single spindle to form a plu-rality of square-ended packages thereon, the strands are shifted to a front waste take-up portion of the spindle by means of a guide which is moved from the rear end to the front end of the spindle across the paths of movements of the strands when the packages are fully wound, to enable the fully wound spindle to be replaced by a new spindle without interrupting the drawing of glass fiber.  The spacing between the spindle and the path of travel of the guide and the speed of travel of the guide are set at a low level and a high level respectively which are sufficient to ensure at least loose portions of the strands, which are produced when they drop into the groove between the adjacent packages, to be immediately wound on the peripheral surface of the adjacent package.

Abstract: Abstract of the Disclosure In the digital detector the center frequency and bandwidth of a digital filter is controlled by a microprocessor.  Amplitude information for the original input signal may be preserved or a simple threshold of energy may be detected within a bandpass.  The microprocessor scans a selected frequency spectrum by digitally changing the decoding data controlled by software.  This detector in conjunction with a scanning algorithm permits data acquisition in addition to energy detection, data acquisition being the process of controlling an incoming signal within a bandpass by moving the center frequency and band-pass of the filter and generating a corresponding error signal as the feedback control signal.

Abstract: ABSTRACT OF THE DISCLOSURE A process for the synthesis of an alcohol mixture, including methanol and higher alcohols of fuel quality involves passing a synthesis gas mixture of carbon oxides and hydrogen at a temperature of about 250-400°C and a pressure in the range of from about 80-150 bar over a special catalyst.  The catalyst consists of the oxides of copper and zinc in intimate association with each other and a promotional amount of a compound selected from the group consisting of chromium, cerium, lanthanum, manganese, thorium and alkali metals.  The catalyst can be made by coprecipitation of two or more of the constituents from a solution of soluble salts to produce an insoluble precipitate, followed by calcination of the insoluble salts to the oxides at temperatures in the range of 350 to 450°C.  Alternately, the catalytically active oxides can be obtained by the thermal decomposition of soluble salts from ammine complexed to produce intimately associated oxides.  The catalytically active oxides are tableted and can be further impregnated in one or more steps by one or more of the promoting metal oxides.  The alcohols produced by this process can be used for fuel or can be mixed with gasoline.  Due to the higher alcohols the gasoline and alcohol mixture does not undergo phase separation in the presence of small amounts of water.  It is also possible to separate the various alcohols by fractionationand use them as starting material for chemical intermediates.

Powder having conductive or resistive component is then spread over the layer 9 embedded into the soft material as a multilayer, and removed from the hard material. Finally, the substrate is fired to burn off the organic layer, to sinter the powder particles together and to fuse them to the substrate. The resin must be from 5 to 10 m thick and the powder from 0.5 to 10 m in diameter in order that the film produced by firing does not have voids or blisters.
