Abstract: ABSTRACT       IMPROVEMENTS IN OR RELATING TO LASER TRANSMITTERS AND METHODS OF OPERATING SAME       A laser has a dc bias current supplied such as to keep the laser normally above threshold, and a modulation current is supplied to bring the laser below threshold when a pulse appears.  In one embodiment a feedback controlled bias current source (11) and modulation current source (15) are coupled to the p-side terminal of the laser (10) while a constant voltage source (27) is coupled to the n-side terminal of the laser in a way which results in subtraction of the modulation current from the dc bias current.  This mode of operation essentially eliminates laser overshoot and more nearly equalizes rise and fall times of the light pulses.

Abstract: "PLASTIC FISHING SPOON TYPE LURE"          ABSTRACT OF THE DISCLOSURE         A spoon type lure is made of plastic and is pre-ferably transparent and colored.  The lure is lightweight, non-corrosive, rustproof and requires no paint which may chip or peel.  If scratched, it can readily be buffed back to its original state.  Being transparent or translucent, it will reflect light both from and through it in all di-rections during use.  Although the surface is normally smooth giving a prism effect, it can, if desired, be im-pressed with a plurality of depressions giving a much greater reflective and refractive characteristic which under good light conditions will give a sparkling effect.    The lure can be used for trolling, casting or jigging and due to the high reflective and refractive characteristics, can be more effective in deep or dark waters.  In one em-bodiment, a bait type object such as an artificial minnow may be embedded into the transparent plastic.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure teaches an actuator assembly having a clutch mechanism with an input disc and an output disc.          Means are provided for rotating the input disc.  Means are provided to prevent rotation of the output disc with the input disc when the assembly is in a rest condition, and for effecting a rotation transmitting connection between the input disc and the output disc when the assembly is in an actuated condition.  Means are also provided for automatically returning the assembly from the actuated condition to the rest condition:  (1) if the first input disc is rotated within a given time delay, upon the rotation; or, (2) if the first disc is not rotated within the given time delay, upon the expiration of the time delay.  Thus, the second output disc can be rotated only once within the time delay, and the second disc is not rotatable at all if the first disc is not rotated within the time delay.

Abstract: ABSTRACT OF THE DISCLOSURE         The internal combustion engine has, arranged in pairs, cylinders offset in angle in relation to one another in the direction of the axis of rotation of its crankshaft.          The engine block consists of two castings, each of which combines integrally in one piece with one another one half of a crankcase, one of the cylinder housings of each pair and the cylinder heads.  The castings are symmetrical in rotation at 180° in relation to an axis of symmetry lying in the plane of separation of the crankcase perpendicularly of the axis of rotation of the crankshaft, so that they can be manufactured in one and the same casting mold.          The cranks of the crankshaft which are allocated to each piston pair are connected with one another through a cranked middle piece, to reduce the distance between the cylinder axes and thus to reduce vibration.

Abstract: A CROSS-POLARIZATION INTERFERENCE CANCELLATION     ARRANGEMENT FOR DIGITAL RADIO CHANNELS            Abstract The present invention relates to a cross-polarization cancellation arrangement for digital radio channels wherein the cancellation arrangement comprises a canceller section and an equalizer section in cascade which operate at baseband. The canceller section includes both main-lobe estimator means and detection circuits.  The estimator means provides a preliminary estimate of the main lobe of the pulse response in each of the two received orthogonally polarized signals.  The detection circuits take each of the estimator means output signals, relating to each received polarized signal, and generates therefrom error control signals for adaptively updating the main lobe estimate signals from the estimator means and also to provide an output signal which is used to cancel the interferer main lobe in the received oppositely polarized signal.  The equalizer section then mitigates intersymbol and cross-rail interference in each of the orthogonally received signals.

Abstract: Abstract The process for preparing water-soluble mixed cellulose ethers proceeds in the following steps: a)  alkalization of the cellulose, b)  etherification of the alkali cellulose in the presence of a base, using at least one etherifying agent which requires, for the reaction with cellulose, a catalytic and sub-stoichiometric quantity of a base, and c)  after increasing the quantity of base, further etherifi-cation of the cellulose ether so prepared, using at least one etherifying agent which requires, for the reaction with cellulose, an at least stoichiometric quantity  of a base or a catalytic and sub-stoichiometric quantity of a base, increased over the quantity used in (a), with at least one inert organic solvent being used as a dis-persing auxiliary in at least one of the steps and water being present in all steps.  The organic solvent used is dimethyl ether, which either is used alone or in a mixture with dimeth-oxyethane, an alkanol, an alkanediol and/or an alkoxyalkanol.          The process serves, in particular, for the preparation of methyl-hydroxyethyl cellulose or methyl-hydroxypropyl cellulose.

Abstract: ABSTRACT   A leg support system for mobile, marine, jackup units of the type having a floating barge having telescoping legs upon which the barge can self-elevate.  The jack towers are movably positioned on the vessel deck and are adapted to tilt into variable angles so that the legs can be spread wider apart when they rest on the bottom of the ocean.  The bottom of the legs are fitted with a foot (can).  With the cans further apart and the legs inclined to preselected variable angles, the stability against overturning is increased, and leg bending moments are reduced during all conditions; including storms, transit, drilling and "punch through."  Because of this adjustable leg inclination feature, the tilted legs inboard chords can be connected to adjacent chords at the top of the legs during transit conditions, thereby reducing the leg stresses.  The jack tower guidance system consists of upper and lower guide rollers which contact the specially shaped chord sections and support the legs as they are extended or retracted by the elevating jacks.          Each jack tower positioning system consists of a pair of hinges on the sides of the respective legs, facing the center of the jackup barge unit, and a yoke tower is located on the side of each leg away from the center of the unit.  The elevating mechanism in the yoke tower can selectively raise or lower the outboard edge of the jack tower, which in turn moves the leg's can in or out from the center of the unit.  The hinges provide fixation in all directions except translation normal to the axis of the hinges.  This system with the rigid frame provides fixation between the jack tower and the hull of the unit.

Abstract: ABSTRACT OF THE DISCLOSURE Light and heavy duty vehicles, such as trailers, require spring suspension systems to mount wheels thereto.  A problem in the spring suspension systems prior to this invention has been that they are permanently mounted on the frame of the vehicle which makes serviceability time consuming and expensive.  The spring suspension system of this invention overcomes this problem by being readily assembled and removed from the vehicle frame and includes a torsion spring cartridge assembly for supporting an oscillating member.  The assembly includes a bearing assembly, a torque assembly mounted for rotary motion in said bearing assembly, a counter-torque hub, and a set of torsion bars connecting the torque assembly to the counter-torque hub.          The cartridge assembly is adapted to be removably mounted in a support structure with the bearing assembly and counter-torque hub mounted in a fixed relation so that the torque assembly is free to rotate within the limits of the torsion bars.  A dampener can be provided to restrict the motion of  the torque assembly in one direction of motion.
