Abstract: ABSTRACT       New and improved techniques, systems and equipment for the practical underground mining of petroleum from both virgin and depleted oil fields under certain geological conditions, are described.  A method of drilling relatively small diamter, drainage-type oil wells using a fluid and cutting control assembly from within an access underground drilled tunnel, is provided.  The fluid and cutting control assembly facilitates the safe underground drilling and installation of the small diameter, drainage-type oil wells which can be operated either under the natural pressures occurring in the geological strata, as gravity drain wells or by suitable secondary treatment measures arti-ficially pressurized to facilitate drainage of oil from oil bearing strata into which such wells are drilled. Techniques and equipment to facilitate the safe drilling of such wells, placing them into production and thereafter controlling operation of the mine workings in a safe and reliable manner, is described, together with the control system, sensors and other equipment required for safe installation and operation of an underground petroleum mine.

Abstract: LOW POWER OFF-CHIP DRIVER CIRCUIT             ABSTRACT OF THE DISCLOSURE    Power dissipation in an off-chip driver circuit is  decreased  by  utilizing  a  selectively  switched transistor  to  discharge  the  base  of  the  output pull-down transistor, and by using a large resistance in the base current path for the first stage of the Darlington pull-up transistors.  An additional tran-sistor having a larger emitter area and coupled to a lower potential source is connected in parallel with the  normal  phase-splitter  transistor  to  provide additional output current sinking capability,  and a current mirror is  connected to control the current through both the phase splitting transistor and the additional transistor to control the turn-on transi-tion of the pull-down output transistor.

Abstract: RAILROAD FROG HAVING MOVABLE WING RAILS                 ABSTRACT OF THE DISCLOSURE         A railroad frog has either a cast or rail-built point, resting on a base plate which is fastened to ties.  A pair of heel rails are attached to the point, to the ties and to traffic rails.  A pair of movable wing rails extend from the toe of the frog to a location adjacent the point of the frog.  At the frog point an open wing rail forms a flangeway with the point, while the other, closed wing rail cooperates with the point to form a continuous tread surface through the frog.  The wing rails are alternately thrown between the open and closed positions by an actuator.  A series of stops define the open wing rail position and act to hold down the open wing rail.  The wing rails have hinges which allow them to move.  The wings rails have a full rail base at the hinges.          Adaptor plates allow use of the frog on concrete ties.

Abstract: HOUSING FOR FLOAT SWITCH MECHANISM               Abstract A sheet-metal housing for a float switch mechanism of the type which can be mounted in an aperture of a tank or vessel. The mechanism comprises a body portion to which the housing is connected, and a float which is held captive in the housing, the latter being electrical-ly conductive and the float carrying an electrical con-tact for engagement with an inner housing wall in re-sponse to changes in the level of liquid in the vessel.          The housing is constituted as a one-piece sheet metal member that is bent into a cylindrical shape from a flat metal stamping, and has a pair of adjoining longitudinal edge portions one of which comprises a lateral offset to enable it to overlap the other. One edge portion has an aperture, and the other edge portion has a tab which extends radially outward through the aperture and is bent back upon the outer surface of the first edge por-tion so as to securely retain the portions against sep-aration. The apertured edge portion is thus sandwiched between the other edge portion and the tab. In addition, there is at least one abutment disposed at the end of the member and extending partially across said end so as to engage and hold the float captive therein. Pre-plated metal stock can be advantageously employed, eliminating the need for plating operations following assembly. The advantage of the present invention over the devices of the prior art is mainly that manufacturing costs are reduced compared to those which would be incurred if the housing were to be made as a drawn sheet metal part.

Abstract: ABSTRACT OF THE DISCLOSURE         A plasma display panel having cathodes, anodes and trigger electrodes wherein the trigger electrodes correspond to a plurality of discharge electrodes which are sequentially scanned and wherein an insulating layer separates the trigger electrodes and the discharge electrodes and where a constant trigger voltage is supplied until the plurality of discharge electrodes corresponding to the trigger electrode have been activated.  In the invention, the trigger voltage is quickly changed and is then returned to an intermediate level and the frequency of a trigger voltage pulse is reduced to one over the number of block discharged electrodes so that the power consumption of the trigger electrodes is greatly reduced and since the trigger voltage is returned to an intermediate level erroneous discharges will not be generated between inactive trigger electrodes and the other discharge electrodes to which data voltage pulses are supplied thus producing a high definition display.  The trigger voltage may swing positive and negative directions with reference to an intermediate level and an ON potential low level of the cathodes which sequentially fall to a low level by scanning activation may be set to be the same as the intermediate level.          Thus, the absolute value of the trigger voltage applied to the insulating layer or dielectric layer between the cathode and trigger electrodes can be substantially one-half a required value and plus or minus one-half with reference to an intermediate level and a breakdown voltage of the insulating layer can be decreased.  Therefore, stable operation will be provided over long periods of time without dielectric breakdown and in addition the insulating layer can be thin and the trigger voltage can be decreased.

According to the invention it is provided that at least one meander-shaped insulated heating conductor is placed on one supporting foil of thermoplastic material and covered by another foil, which may be identical, whereby the thermal dimensional stability of the heating conductor insulation exceeds that of the foils by approximately 50%, that subsequently by supplying heat and pressure a firmly connected heating element is formed, its heating conductor lying in the meander-shaped channels designed according to the laying pattern without a bond to the foils resulting, and that the elastic properties of the heating element are adjusted in conjunction with the selection of the smallest possible meandering distance such that in the unstressed state a long length of the heating conductor is given so that the heating element is nondestructively expandable up to at least double the length and width at each loaded point.  The heating elements thus constructed are connected to the cushion cores, whereby in the case of deep-drawing the arrangement is on the inside of the cover.
