Abstract: A casing  stabbing apparatus which  includes  a derrick bracket subassembly for attachment to a derrick, and a boom having an end pivotally connected to the bracket assembly for pivotation about a vertical axis and about a horizontal axis.   A pair of arcuate casing gripping jaws is pivotally connected to the second end of  the boom.   A piston and cylinder assembly extends between the jaws to selectively converge and diverge the jaws.  A second piston and cylinder assembly extends between the bracket assembly and the boom to elevate the boom by pivotation about a horizontal pivotal axis.  A third piston and cylinder assembly extends between the  bracket  assembly  and  the  boom  to  swing  the  boom laterally in pivotaion about a vertical axis.   A remote automatic control subassembly enables the casing stabbing operation to be carried out from a remote location by the use of a hand held wand.

Abstract: ABSTRACT OF THE DISCLOSURE    An apparatus for use in inhaling pharmaceutical aerosols.  The apparatus includes a mouthpiece and a rigid housing for receiving an aerosolized medicine. The rigid housing has one or more orifices which are spaced from the mouth piece so that flow through the housing is possible but is limited by the orifice(s) to a desired volumetric flow rate.  The patient is aided by having the initial velocity of the aerosolized medicine reduced to zero by virtue of the initial delivery of the same to the housing interior, and by having the volumetric flow rate of the inhaled medication maintained below required limits thereby providing the conditions for optimal dosing.  Further, the ability of the patient to inhale to total lung capacity with the flow through chamber enhances penetration of aerosolized drug to the lung periphery, and improves the ease of use for the patient.

Abstract: The present invention relates to a communication system suitable for the communication of data between a plurality of secondary units and a primary unit, and in a presently preferred implementation relates to improvements in radio data communication systems wherein mobile terminals transmit data to a primary processor under a wide range of operating conditions.  The primary processor may transmit a multiterminal polling signal defining a series of successive response time slots which the terminals may randomly select.  A terminal wishing to send a message transmits a brief response burst in the selected time slot giving its identification.  The primary processor may them sequentially poll specific individual terminals having messages to send.  The primary processor may maintain a record of currently active terminals and/or of collisions (where more that one terminal seeks to transmit in the same response time slot), and as needed may automatically send e.g. with its multiterminal poll, a time slot number change, creating a greater or lesser number of time slots for future use by the active terminals. The system is thus highly adaptable on a dynamic basis during operation so as to readily maintain optimum throughput under changing conditions.  As a consequence, additional terminals may become active simply by transmitting their respective identifications in randomly selected response time slots.
