Abstract: ABSTRACT OF THE DISCLOSURE       The pump has a pumping chamber with a deflectable diaphragm member and fluid inlet and outlet passages. A deflectable valve flap is disposed across the fluid inlet passage and another flexible valve flap is disposed across the fluid outlet passage. Movement of the flexible valve flaps is responsive to movement of the flexible diaphragm member, reciprocation of which establishes alternate sequential suction and discharge conditions. An air chamber pro-vided in the pump receives outside air through an air vent opening and also communicates with the pump discharge passage through a bleed hole when the outlet passage is closed by the outlet valve flap. The outlet valve flap is also deflectable to a position where it closes the bleed hole. Under this arrangement, continuous siphon-in of fluid through the pump after the pump has been shut down is obviated. In the event that an obstruction occurs at the dis-charge section of the pump the outlet valve flap will move to a position intermediate the outlet passage and the bleed hole thereby permitting discharged fluid to bypass the discharge section of the pump and return to an inlet supply portion of the pump.

Abstract: ABSTRACT      A vehicle rack having frame members and a clamping device for securing a ladder to the frame members.  The clamping device comprises a first clamp rigidly connected to one frame member to receive one of the rungs of the ladder, and a second clamp for engaging another rung of the ladder.  The second clamp is rigidly connected to a rotatable rod to which a handle as connected.  A link is provided for interconnecting the rod and a spring, the arrangement of the link and the member being such that the second clamp is biased alternatively in the engaged and disengaged positions so that moving the handle means in one direction will cause the second clamp to engage a rung of the ladder, the second clamp being urged in the engaged position by the spring.  While moving the handle means in the other direction will cause the second clamp to disengage, the spring then urging the second clamp in the disengaged position.

Abstract: Method and device for controlling the erosion of the electrodes of a plasma torch, in which an electrical arc is produced when the electrodes are connected to an electrical supply. An axial magnetic field generated by a system of field coil causes the rotation of the extremities of the arc according to a circular trajectory inside the electrodes. The relative position of the field coils is such that there exists a position on the electrode surface where the value of the total magnetic field is a minimum where the arc runs thereby controlling the erosion of the electrodes. According to the invention, the value of current is periodically varied in the system of field coil used to cause the rotation of the arc, thereby producing a controlled axial displacement of the circular trajectory of the extremity of the arc. The plasma torch according to the invention is characterized by structure to periodically vary the value of the current in the field coil system used to cause the rotation of the arc thereby producing a controlled axial displacement of the circular trajectory of the extremity of the arc. Under these conditions, the life of the electrodes is substantially increased.

Abstract: Abstract of the Disclosure This invention is directed to a new membrane lytic immunoassay.  In one embodiment of this assay, an antigen is first covalently coupled with lipids and this antigen-lipid complex is mixed with a hexagonal phase forming lipid to form bilayer liposome vesicles additionally containing a self-quenching fluorescent dye.  When this antigen-containing liposome is brought into contact with a solid surface coated with antibody molecules, binding occurs between the antigen and the antibody, disrupting the liposome and releasing the dye.  To assay a biological fluid for free antigen the fluid is first contacted with the solid surface-antibody complex, to saturate the bound antibody.  Binding by the liposomes is thereby inhibited, leading to reduced dye release.  Comparing dye release against a standardized curve of dye release versus known antigen concentrations allows for rapid determination of the unknown antigen concentration in the biological fluid.  Similarly, antibodies and other entities, e.g., enzymes, drugs, etc., may be determined using slightly modified versions of this assay.

Abstract: CONTROL APPARATUS AND METHODS, HEAT TRANSFER SYSTEMS AND APPARATUS AND METHODS FOR CONTROLLING SUCH SYSTEMS AND FOR SENSING AND INDICATING   LOW FLUID CHARGE CONDITIONS THEREIN                  Abstract of the Disclosure Control apparatus for producing a control signal indicating that a physical variable has reached a userselected level.  A transducer generates for the control apparatus elec-trical pulses having a repetition period which is a function of the physical variable.  The control apparatus repeatedly counts clock pulses in response to the transducer pulses to provide a first digital signal representative of the repeti-tion period of the transducer pulses.  The apparatus also repeatedly generates a second digital signal corresponding to the user-selected level of the physical variable by adding to a preset binary code a binary amount related to a user-selected voltage.  The first and second digital signals are compared to produce the control signal for a switching circuit which responds thereto.  The comparison is overridden if an analysis of most significant bits of the first digital signal shows that the physical variable varies beyond a prede-termined level.  In control apparatus for a heat transfer system the comparison is made with a high fluid pressure level, and a low charge pressure level, as well as a user-selected low fluid pressure level.  Subject to predetermined time delays, the system is actuated when the high pressure is reached, and deactuated when the selected low pressure is reached.  Abnormally low fluid charge -is indicated when an excessive rate of change from the high pressure level to the low charge pressure level repeatedly occurs.  An automotive air conditioning system and methods for controlling such a system are also described.

Abstract: SYSTEM FOR SELECTIVELY COUPLING A PLURALITY OF      STATIONS INTO A SINGLE COMMUNICATIONS PATH     Abstract of the Disclosure A system is disclosed for selectively serially coupling a plurality of stations in a commu-nications network into a single communications path.          In the system of the invention, a plurality of tap boxes are serially coupled into the single communica-tions path.  Each station is coupled to a desired associated one of the tap boxes by way of an associat-ed tap cable.  When the tap cable is connected to a first portion of the tap box, a first impedance corre-sponding to the characteristic impedance of the single communications path is serially coupled into the single communications path to enable the station associated with the tap cable to be coupled to the single communications path by way of the first imped-ance.  When the tap cable is connected to a second portion of the tap box, the first impedance is effec-tively removed from the single communications path and a test impedance is coupled to the tap cable to enable the station associated with the tap cable to test itself.  In a first embodiment, the first and second portions of the tap box are respectively the tip and ring contacts of a stereo jack.  In a second embodi-ment, the first and second portions of the tap box are separate audio jacks.  In each embodiment, a connec-tion means, such as a monaural plug, is connected to the end of each tap cable and is used to selectively couple the tap cable to either of the first and second portions of a desired tap box.

Abstract: Abstract of the Disclosure:     In a multilevel modulator for use in modulating a main data signal of n bits and a subdata signal of a single bit into a multilevel quadrature amplitude modulated signal, the main data and the subdata signals have a first bit rate f1 and a second bit rate f1/m, respectively, where m is a positive integer which is not less than two.  A converting circuit converts the main data signal according to the subdata signal into a binary intermediate signal.  The binary intermediate signal is processed by a digital-to-analog converter and a modulator into the multilevel quadrature amplitude modulated signal having output signal points of (2n + .alpha.) where .alpha. represents an integer which is not less than zero and is not greater than 2n/m.  A multilevel demodulator carries out an inverse operation to reproduce the modulated signal into the main data signal and the subdata signal.
