Abstract: CONDUCTION HEATING OF HYDROCARBONACEOUS FORMATIONS              ABSTRACT OF THE DISCLOSURE            A waveguide structure is emplanted in the earth to bound a particular volume of an earth formation with a waveguide structure formed of respective rows of discrete elongated electrodes wherein the spacing between rows is greater than the distance between electrodes in a respective row and in the case of vertical electrodes substantially less than the thickness of the hydrocarbonaceous earth formation. Electrical power at no more than a relatively low frequency is applied between respective rows of the electrodes to deliver power to the formation while producing relatively uniform heating thereof and limiting the relative loss of heat to adjacent barren regions to less than a tolerable amount.  At the same time the temperature of the electrodes is controlled near the vaporization point of water thereat to maintain an electrically conductive path between the electrodes and the formation.

Abstract: MULTI-FUNCTION DATA SIGNAL PROCESSING METHOD AND APPARATUS            Abstract A data signal is processed to change its form and spectral content without introducing undesirable frequency and amplitude effects.  Multiple data signal states, which determine the essential characteristics of the output signal wave configuration, are utilized in conjunction with clock signals at a rate substantially in excess of twice the largest frequency component of the data signal in order to read from a memory a bit-duration waveform sample set representing the desired output signal wave configuration.          Predistortion to compensate for anticipated transmission effect is also included in that configuration.  In one embodiment, an input data signal is in an NRZ format and is processed for conversion to the biphase, or Manchester, format by a ROM table look-up function addressed jointly by the input signal states and the clock signals.

Abstract: CARRIER FREEZEOUT FIELD-EFFECT DEVICE            Abstract A buried-channel MOSFET device 10 is cooled sufficiently to experience majority carrier freezeout in the channel region 30 (e.g. 10°k).  It is appropriately fabricated and biased to form a buried-channel 40.  when the gate 26 is pulsed, there appears in the buried channel 40 a transient conducting condition which lasts for on the order of 10-8 second or more and may therefore be used for subnanosecond switching functions.  The switching energy needed for turning the device 10 on is very low, of the same order of magnitude as for Josephson junction devices.  Turn-on is dependent mostly on the height of the switching pulse, rather than upon a voltage threshold relative to the source voltage.  This makes possible a large scale integration of such devices with the same switching voltage as that required for a single device. (FIG. 1).

Abstract: ABSTRACT A single two dimension radar system having the capability of developing two dimensional data on all targets in its surveillance volume and three dimensional data for selected targets in its surveillance volume is disclosed.  A single phased array antenna having two selectable elevation beam patterns, a wide beam and a narrow beam, is rotated in azimuth.  In the two dimension mode, targets are detected and tracked in an azimuth and range position through use of the wide elevation beam.  Upon selecting a particular target in track for three dimension data extraction, the radar system changes to the three dimension mode prior to the azimuth position of the selected target, and performs a sequential lobing process of the narrow beam in elevation angle.  The power ratios of the target returns in the sequential lobes are analyzed and an elevation position of the selected target is determined.  The radar system reverts to the two dimension mode after leaving the azimuth position of the selected target.

Abstract: PATENT APPLICATION OF William D. Emmons and Wayne E. Feely for HYDROCURABLE AMBIENT CURING POLYEPOXIDE COATING AND ADHESIVE COMPOSITIONS AND METHOD OF USING THEM          Docket 78-72   By:   CAC/LEJ/jep 0737d/        This application 18 a divisional application of Canadian Application No. 368,788 filed January 19, 1981.          Abstract of the Disclosure Resin-forming polyepoxides are mixed with poly-oxazolidinyl compounds or polymers containing pendant oxazolidinyl groups in which the carbon atom in the 2-position of the heterocyclic ring is substituted with saturated hydrocarbon groups, such as dialkyl, or with an alkylene group forming a saturated ring with the carbon atom in the 2-position of the oxazolidinyl ring to form, in the absence of water, a stable composition which can be stored in closed containers for months without undergoing gelation.  When such compositions are spread into films and the films exposed to moisture at ambient temperature, e.g., to ambient air having a relative humidity of at least 20% and temperature of about 15° to 25°C., the polymer serves to react with and cure the polyepoxide.

Abstract: ABSTRACT OF THE DISCLOSURE SURE    A manually releasable, spring-a-plied, air-released parking brake device has a hollow guide rod and a non-rotatable spindle connectable to the brake rigging extending through a portion of a cylindrical housing.  On one end of the guide rod is secured a portion of a clutch arrangement, and on the opposite end is secured a spline member having a plurality of externally dis-posed spline grooves.  The connection between the guide rod and clutch portion provides coincident movement by such two members.         The spline member, being similarly secured on the opposite end of the guide rod, moves coincidentally with the guide rod and clutch portion.  A latching member having an extending surface engages the spline grooves of the spline member, thus preven-ting rotational movement of the spline member, guide rod, and clutch portion.  A release lever, connected to the latching member, provides a means for engaging and disengaging the latching member and spline member.  When the latching member has been disengaged from the spline member, as corresponds to a manual release of the parking brake device, a retractable blocking member is urged against the end surface of the spline member.  The blocking member prevents engagement of the latch-ing member and spline member, thus no longer preventing rota-tional movement of the spline member.  With the spline member, guide rod and clutch collar now rotationally movable, the brake-applying spring force is dissipated away from the force-applying spindle.  To reset the parking brake device air is introduced to piston chambers, moving a plurality of pistons in a direction to compress a plurality of brake-applying springs.  The guide rod then moves to a position whereby said blocking element is moved out of blocking position between the latching member and spline member.  A return spring contacts the release lever, urging the release lever to a position cor-responding to engagement between the spline member and latching member.

Abstract: ABSTRACT     Electrical vacuum switch provided with two mutually movable contacts of conductive material, mounted on the ends of a fixed or movable contact rod, with a laminated horseshoe-shaped ferromagnetic element being fitted around each contact rod. The magnetic circuit around the contact rod consists of a section of low magnetic resistance and a section of a high magnetic resistance. The circular base of the U-shaped inner cavity of the horseshoe-shaped element is adjacent to the associated contact rod and the elements are offset through 180°C with respect to each other, so that the internal magnetic fields generated in the horseshoe-shaped elements when current passes through the switch, to the extent that the section with high magnetic resistance is approached, are mainly oriented axially between the two horseshoe-shaped elements. Said elements are so designed that their magnetic resistance to the internal magnetic field increases in going from the U-shaped base section to the section with high magnetic resistance.

The two positioning elements are arranged so that the tip of the needle of the hypodermic syringe is inside the ampoule when the syringe and ampoule are located in the device. From the first positioning element a pin protrudes axially and carries first and second stops cooperating with the end of the plunger. When liquid is to be drawn in to the hypodermic syringe the plunger is drawn out until its end part meets the first stop. The first ampoule is then replaced by an ampoule containing a different type of liquid. The pin is then turned to move the first stop to leave a free passage for the end of the plunger, after which the plunger is drawn out further until its end comes into contact with the second stop. The hypodermic syringe now contains a correct mixture of the two liquids and is ready for injection.
