Abstract: THREADING ATTACHMENT                  ABSTRACT OF THE DISCLOSURE     A reversible driver for a threading tool, such as a tap or die, is disclosed.  The driver has rotary input and output members with a forward clutch connected therebetween and a reverse clutch connected through reverse gearing between the input and the output members.  Each clutch has drive and driven clutch elements and a first spring urges both forward and reverse clutches toward engagement.  A second spring is stronger than the first spring and urges the forward clutch toward engagement so that a tap rotated by the output member will tap a hole in a workpiece until the for-ward clutch is released.  Each clutch utilizes a plurality of substantially hemispherical projections engaging longitudinal abutments as a form of dog clutch.  The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

Abstract: METHOD AND APPARATUS FOR OFF-LOADING      A COMPLETED UNCURED TIRE                   Abstract of the Disclosure A completed, shaped and uncured tire is off-loaded from the tire building machine 10 on which the tire has been built by first engaging the completed tire coaxially within a ring 14 having radially movable seg-ments and then moving the ring 14 with the tire coaxially off the building machine 10 to a chucking device 20 engage-able with the inner peripheries of the respective bead portions of the tire.  The ring 14 is then expanded and moved coaxially from the tire and the chucking device 20 now holding the tire is rotated to place the tire axis in vertical orientation and elevated to a position above the tire machine 10 where the exterior surface of the tire is grasped by a pair of palms 32 mounted on a swing arm 33.  After the chucking device 20 is moved downwardly clear of the tire, the tire is then moved horizontally by the swing arm 33 and deposited on an overhead belt conveyor to be transported thereby to further processing.  The tire building machine operator is relieved of the effort and time required for manual removal of the tire and the completed tire is protected from inadvertent damage due to manual handling.  In particular, the tire is elevated from the operating floor in a convenient and expeditious manner.

Abstract: ABSTRACT     IMPROVED THERMOCOUPLE APPARATUS FOR INDICATING              LIQUID LEVEL IN A CONTAINER        An improvement is provided in thermocouple apparatus for indicating liquid level in a container, particularly a continuous casting mold.  The conventional apparatus includes a plurality of thermocouple elements of first polarity connected to the container at spaced levels above and below the liquid and to corresponding spaced points on a slide wire resistor.  The container wall acts as the thermocouple element of opposite polarity.  A conductor probe is connected to the wall and to a point on the resistor above the uppermost thermocouple element to provide a reference voltage at that point.          The probe and thermocouple elements extend to locations adjacent the exterior face of the container which may be subject to substantially variable ambient temperature.  The improvement of this invention involves substitution of a portion of the length of either the probe or the thermocouple elements with, a material substantially equivalent to the thermocouple element of first polarity in the case of the probe, or a conductor material equivalent to that of the probe in the case of the thermocouple elements.  The substituted portions extend from an internally cooled region of the wall of the container to a location adjacent the exterior of the wall.

Abstract: ABSTRACT OF THE DISCLOSURE     An improvement in continuous metal casting machines of the type having a pair of flyable, moving casting belts which revolve along endless paths for defining a casting region therebetween and moving side dams which revolve along with the casting belts for confining the east strip, slab or bar laterally.          The casting belts are individually supported by upper and lower carriage  means.   The machine is provided with sensors such as load cells for sensing the displacement forces existing between the upper and lower carriages at selected points along the path of belt travel, and for sensing the side pressures exerted upon the side dams by the cooling, solidifying metal.          This sensing permits the maintenance of predetermined, desired contact pressures along the length of the solidifying metal to thereby improve the physical characteristics of the cast product.          The sensor outputs may be utilized to manually adjust the pressure points or, alternatively, may be employed in an auto-matic feedback system for providing automatic control of the various casting parameters affecting mold contact pressures and pressure distribution.

Abstract: A B S T R A C T       The asphalt laying machine comprises a rear body di-vided into sections with smoothing and compacting units sus-pended through vibration dampers in the frame.  Each unit comprises an intermediate part and a smoothing part inter-connected by means of a rear shaft bearing and a front con-necting rod  connected to an eccentric.  By virtue of this interconnection an elliptical movement is transferred to the smoothing part during operation of the machine, and this movement produces a heavy tamping at the front edge, a smoothing and vibrating effect at the intermediate area of the ironing plate, and a succeeding tamping and polishing effect at the rear edge area.  The tamping foot of a scraper plate suspended on the intermediate part tamps laid asphalt syn-chronously in opposition to the tamping plate of the ironing plate by virtue of reaction forces transferred through the intermediate part.  During the operation of the machine,the smoothing and compacting unit ensures an unusually densely compacted and uniform surface of the asphalt.

Abstract: PRESSURE SENSOR FOR DETERMINING AIRSPEED, ALTITUDE AND ANGLE OF ATTACK   ABSTRACT OF THE DISCLOSURE A strut or boom mounted probe having separate pressure sensing ports or sets of ports axially spaced at three locations on the probe.  The ports are normally located on the probe so that at 0° angle of attack, the pressure difference is zero between a set of opposite ports at the most rear location.  As the angle of attack varies from zero angle, the pressure difference at the aft measuring ports increases, in a positive sense with increasing angle of attack (alpha), and, in a negative sense with increasing opposite (negative) alpha angle. Pressure difference between the rear ports is also proportional to the impact pressure, qc, where qc = pitot pressure minus static pressure = pt - p.  The sensor normally has a pitot pressure opening in its forward extremity and static ports located along the forward cylindrical barrel section of the unit.  The pressure difference at the rear ports is divided by the pressure difference of the forward ports.  A unique ratio of pressure is developed which is a function of angle of attack or flow direction and pitot pressure and this alternate ratio may be utilized using pitot and alpha (angle of attack) pressure only.  The sensor is particularly useful at high angles of attack and provides readings at angles of attack in the range of ? 50°.  Angles of side slip (beta) and other flow angles in an established measuring plane may be sensed as well.
