Abstract: ABSTRACT     The present invention relates to vehicles comprising pressurized fluid cushions and more particularly to the means for controlling steering of the latter.     The means for controlling steering are formed by vents (EV) supplied by withdrawing pressurized air from one of two lateral regions of the diffusion chamber (D) of the vehicle defined on either side of the longitudinal axis of the latter.  The vents (EV) eject air in a direction having at least one component directed from the lateral withdrawal region towards the opposite region.  Apart from the direct effect (F(EV)) due to the air ejected by the vents, this particular arrangement creates a jet reaction (F(R)) and a hydrodynamic drag and when travelling on the ground, a frictional drag.

Abstract: 23,015CN                  ABSTRACT OF THE DISCLOSURE     One primary  electrode,  each,  of  a  two-triode differential amplifier are coupled together to a negative potential.  One triode's control electrode receives an analog signal; the other is grounded.  A resistively loaded triode couples a positive potential to the first triode's second primary electrode.  A fourth triode, connected to the resistive load, couples the positive potential to the second triode's second primary electrode. One primary electrode each,  of a second two-triode differential amplifier, are coupled via suitable means to a negative potential source.  The fifth triode's control electrode is coupled to the first triode's second primary electrode.   The sixth triode's control electrode is coupled to the second triode's second primary electrode. A resistively loaded seventh triode couples positive potential to the fifth triode's second primary electrode. A resistively loaded eighth triode couples positive potential to the sixth triode's second primary electrode. A switching circuit includes means for receiving a storage pulse for coupling one control electrode of a three triode latch and means for coupling an inverted form of the storage pulse due to suitable means to tend to disable the suitable means.  The improvement resides in the suitable means which comprises a twelfth and thirteenth triode, each of which has a control electrode coupled to receive the inverted form of-the storage pulse, a first primary electrode coupled to receive the negative potential source, via the second conductive medium, and second primary  electrodes  coupled  to  receive  the  primary electrode of the fifth and sixth triodes, respectively.

Abstract: TITLE Non-Electric Blasting Assembly ABSTRACT OF THE DISCLOSURE          A percussion-actuated instantaneous or delay detonator  transmits a detonation from a first length of low-energy detonating cord (LEDC) transversely positioned adjacent the detonator's percussion-responsive end to a U-shaped segment of a second length of LEDC held with its apex against the base-charge end of the detonator and the arms of the U extending away from the detonator.  A directional connector for connecting a U-shaped segment of detonating cord adjacent each end of the detonator has identifiable donor- and receiver cord-housing sections, e.g., the receiver-cord-housing section has the shape of the head, and the donor-cord-housing section the shape of the butt, of an arrow. A connector adapted to hold receiver LEDC and high-energy detonating cord (HEDC) segments is internally configured to receive nested U-shaped segments of LEDC and HEDC only when the LEDC is adjacent the base-charge end of the detonator.

Abstract: ABSTRACT OF THE DISCLOSURE        A continuous feed mechanical pencil includes a lead cartridge having a lead advancing mechanism responsive to forward axial movement of an actuator button protruding from the rear end of the instrument,  the actuator button being fixedly attached to a pocket clip and extending a relatively short distance from the rear of the instrument housing so that the rear end of the actuator is shrouded by the rear end of the housing when the actuator button is fully depressed.                      SPECIFICATION      The present invention relates in general to mechanical pencils having a push type lead advancing mechanism, and it relates in particular to a new and improved actuator mechanism which prevents the application of excessive force to the lead advancing mechanism.                    BACKGROUND OF THE INVENTION  Push type mechanical pencils generally employ a rearward-ly extending actuator button which is depressed to advance the lead from the forward tip of the instrument.  Push pencils of this type have two important advantages over mechanical pencils having a rotary or twist type lead advancing mechanism.  One such advantage is that actuation is simpler and more convenient.          A second advantage is the fact that the pencil need be loaded with lead much less frequently because a plurality of lead sticks placed in the cartridge are automatically fed seriatem to the lead advancing mechanism in the cartridge.  Nevertheless, for
