Abstract: CONNECTOR FOR CO-AXIAL CABLE                      A B S T R A C T An integral mandrel connector for co-axial cable. The connector has two major assemblies which telescope together and grip the prepared end of the cable. Elements of the connector tighten on the cable jacket and grip the cable center conductor, all simultaneously, when the two threaded assemblies are engaged and tightened together. A collar inside one assembly moves axially a short distance upon tightening of the assemblies to cause a chuck to grip the center conductor while the cable jacket is also being positively gripped by other connector elements. The connector can be employed for splicing two pieces of cable together, for adapting cable of one size to a different size cable, and for coupling to external equipment such as an amplifier.

Abstract: ABSTRACT    The accuracy of well logging data transmitted from a downhole location to the surface of the earth is verified by generating the data at the downhole location, storing the data in a subsurface assembly in the well, transmitting sig-nals corresponding to the data to the surface through a first transmission system while keeping the data stored in the sub-surface assembly, and recording the signals transmitted to the surface through the first transmission system.  There-after, the subsurface assembly is transferred to the surface, and signals corresponding to the stored data are transmitted through a second transmission system from the assembly to an electronic processing system.  The signals transmitted through the second transmission system are then compared with the signals transmitted through the first system.    To increase the effective transmission rate of data from the downhole location to the surface, a first set of signals corresponding to the magnitude of a downhole condition as a function of time during a discrete time interval are gene-rated and transmitted through a first transmission system to computer means at the downhole location.  The first set of signals are analyzed in the computer to determine properties of the function selected from the group consisting of mean value, positive and negative peak values, standard deviation value, and fundamental and harmonic frequencies and ampli-tudes.  A second set of signals corresponding to the selected values are generated and transmitted to the surface through a second transmission system.

Abstract: ABSTRACT         A TE laser amplifier has a fully closed metal housing (2).          This fact, its geometry and that of its electrodes (5-7) and/or the reversal of the output polarity make possible a homogeneous field distribution, a capability to influence the local amplification process in the laser medium and result in a relatively long life-time of the gas and the laser (Figures 5 and 6).

Abstract: ABSTRACT OF THE DISCLOSURE    An injection device particularly suitable for the intraruminal injection of medicaments into ruminants is described.  The injection device is characterized by a needle carrying means and a needle actuation means, which are operatively coupled such that the needle actuation means permits movement of the needle carrying means from a retracted position to an extended position, wherein the needle is capable of piercing the rumen, only when the needle carrying means is in a preferred orientation (e.g. perpendicular) to the surface of the host animal at the injection site.  The injection device is further characterized by a dose delivery actuation means which is responsive to the relative position of the needle carrying means and the needle actuation means such that the dose is delivered to the host animal only when the needle carrying means and the needle actuation means are in a preferred position relative to each other.  The characteristic features of the described injection device substantially prevent the application of a dose to a host animal not within an intended dose delivery area.

Abstract: Abstract of the Disclosure:     A bag filling kit has a hollow stand having side walls and spaced opposite first and second open ends.  The stand is circular at its second open end.  A funnel, separate and independent from the stand, has side walls, spaced opposite first and second open ends, a funnel neck at the second end and a clamping device at the funnel neck.   The side walls taper down from the first end to the second end and the clamping device is dimensioned to fit over the second end of the stand and releasably clamp the neck of a flexible bag to the outside of the second end of the stand with the remainder of the bag in the stand when the neck of the bag is bent over the outside of the stand neck.          The bag is thus fillable with material via the funnel when the funnel neck is inserted into the open neck of the bag.

Complete combustion of the volatile substances is accomplished in the furnace to yield gases which are free of the volatile organic substances.  The blocks later attain a final baking temperature of up to about 1,200°C.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to a two-stage method for cleaning waste gases contaminated with gaseous pollutants, more particularly waste-gases arising from combustion.  In the first stage, a dry reaction agent in powder form is injected into the flow of gas.  In the second stage, clean water or an aqueous solution or suspension of a reaction agent is sprayed therein.          In the first stage, the reaction with the pollutant gases pro-duces a surface layer upon particles, which inhibits further reaction.  The water added in the second stage reactivates the particles, allowing them to bind additional pollutants and thus provide better utilization of the reaction.  The amount of water added may be kept so small that, even if the initial temperature of the waste gas is relatively low, the temperature does not drop below the dew point.  In one aspect, the invention provides a method for cleaning waste gases, more particularly combustion gases, contaminated by gaseous pollutants such as SO2 and HC1, wherein a reaction agent in the form of a powder is added in a first stage of the method and an aqueous medium is added in another stage, the added water being completely evaporated, characterized in that the aqueous medium is added downstream of the location at which the powdered reaction agent is added.
