Abstract: ABSTRACT OF THE DISCLOSURE     A tire building machine of the expandable bead lock type employs an elastomeric specially shaped radially expanding bead lock which includes an air passage system therethrough. The bead locks are expanded by a pneumatic tube which seats the bead lock against reentrant shoulder stops securing the bead locks in their expanded condition both precisely radially and axially with respect to the two centerlines of the machine. Such bead locks may be used in connection with an expandable axially tired center deck for first stage operations or in connection with a substantially rigid axially expandable and contractible center deck for single stage operations. The bead locks may also be employed for second stage operations. For a single stage machine, the preferres form of center deck includes axially oppositely extending ringers which slide in respective slots in the center support  forming a substantially rigid working surface. In connection with single and first stage operations, the bead locks may include integrally formed shaping bladders which are inflated through the air passage system in the bead locks.  An additional bladder may be employed at each end of the machine cooperating with the bladder formed integrally with the bead locks for turning tire components about the beads and for assembling components such as sidewalls to the carcass when in toroidal shape.  The bladders are specially constructed and molded so that the components may be wrapped or applied tangentially and sequentially from the bead outwardly to avoid distortion.  Components of the machine, whether used as a single stage, first stage, or second stage machine are common.

Abstract: Abstract of the Disclosure There are disclosed two embodiments of a fastener, a method of using a fastener, and a fragmentary portion of a mold.  The fastener has a socket and a head joined by a flexible filament.  The socket has a disc-shaped body, a transverse opening through the body, projections extending into the opening, and a post joined to each projection. The posts extend into the space within a side wall of the opening.  The projections flex when the head is inserted through the opening, but the posts prevent attempted with-drawal of the head through the opening thereby preventing uncoupling of the head from the socket.  The projections are so close that when the head is inserted into the socket, some of the plastics polymeric material of the projections deforms permanently, thereby work hardening the projections at the deformation.

Abstract: TURBINE AND METHOD FOR ASSEMBLING SAME                        Abstract A turbine assembly is provided by which a variable area turbine vane may be cantilever mounted from an outer structural frame and further supported by an inner structural frame. The vane includes an inner trunnion about which is installed an inner band sector to partially define a flow path through the turbine. The band sector is provided with a hole which receives the trunnion. Once the vane is cantilevered from the outer frame and the band sector installed, an inner annular frame is slid under the vane trunnion to align a hole in the frame with the trunnion. A generally cylindrical trunnion extension is inserted through the frame hole and over the end of the trunnion, and then attached to the trunnion through a bolted connection. The extension is journaled for rotation within the inner structural frame hole. Passageways are provided to route cooling air from the vane into the struc-tural frame to provide cooling of the band sector. Such a structure eliminates the need for expensive uniballs or matched assembly halves at the inner end of the turbine vanes.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved slide fastener of the type having opposed strings or rows of interlocking teeth or elements brought into engaging and dis-engaging relationship by a slider element includes a pair of especially adapted terminals which facilitate the engagement of the ends of the slide fastener and facilitate the initial movement of the slider to bring the teeth into engagement.  The terminals are engagable by being brought together in a direction substantially perpendicular to the strings of the slide fastener.  One of the terminals is configured to have a receiving aperture at least about several times larger than the area defined by one of the ports or teeth receiving openings in the slider for receiving the interlocking teeth to enable handy engagement with the other terminal.  Once engaged, the terminals are essentially self-aligning, and are free to rotate relative to each other to permit the opposed rows of the slide fastener elements to self-align as the slider is urged forward.

Abstract: .P - 78906 DUAL SLIDE SWITCH VOLTAGE ENCODER                       ABSTRACT    A dual slide switch voltage encoder is provided in which a plurality of analog voltages are produced as output signals of the encoder at a single output terminal.  Two three position slide switches having manual actuators are utilized to provide a series of nine different analog output voltages having substantially equal increments in magnitude therebetween.  A reference voltage from a microprocessor is utilized to develop these analog output voltages which are subsequently fed into an analog to digital converter in the microprocessor.  Thus the present invention utilizes two three position slide switches to create a series of analog voltages having equal increments in magnitude therebetween wherein each of these analog voltages represents a different logic state corresponding to a specific combination of the various possible mechanical positions of the manual actua-tors of the two three position slide switches.

Abstract: ABSTRACT OF THE DISCLOSURE     In a ring channel aeration system,circulation is provided by one or more hydraulic jumps while the major portion of the energy consumed in aeration is allocated to the release of oxidative process gas through horizontally non-propulsive bubble release means having an oxygen transfer efficiency of at least about 6.  The hydraulic jump(s) may be powered by discharge of gas (e.g. the same gas used for aeration) through gas discharge means, in which case the system of gas discharge means and bubble release means may have an overall oxygen transfer efficiency of at least about 6.  The invention has advantages of flexibility and resultant energy savings as compared to single device circulation/aeration systems, in that excessive energy need not be consumed in aeration to obtain the requisite circu-lation and vice versa.

Abstract: ABSTRACT OF THE DISCLOSURE A paint guide has an inverted U-shaped frame with a flexible paint shield terminating in a straight edge which is adapted to be spaced a predetermined distance from a window frame to provide for a strip of weatherproofing paint on the glass adjacent the frame. An L-shaped bracket is adjustably mounted on each of the ends of the frame and is pivotally slidably mounted on an elongated supporting arm by a link and slidable pivot pin arrangement. A coil leaf spring extends between the bracket and arm and biases the bracket away from the arm to move the paint shield edge out of engagement with the glass. A tab is provided on each of the arms and is located rearwardly of and beneath the fronts of the arms to support the paint guide on a pane of glass when the arm fronts are placed in abutting engagement with the frame. When inward pressure is applied to a handle, which is mounted on the frame, the paint edge is moved vertically into engagement with the glass and spaced a predetermined distance outwardly from the frame due to the engagement of the links in the bracket slots. Continued pressure on the handle seals the paint edge tightly against the class as the rear portion of the frame moves slightly rearwardly due to the flexibility of the paint shield and the slidable pivot pin mounting arrangement between the bracket and arm. After completion of the paint application between the arm, the pressure on the handle is released, whereupon the leaf spring raises the paint edge ver-tically from the glass, after which the guide is slid to an adjacent unpainted area.

Title: Production of powdered resin and the powdered resin so produced
Inventor: PIROTTA MARICO G
IPC: C08J3/12
Filed: 1980-08-18
Granted: 1983-07-19
Abstract: ABSTRACT Powdered synthetic polymeric resin is produced by swelling or shrinking resin particles by contact with water or an organic solvent to introduce strain within the particles and comminuting the swollen or shrunk particles by grinding them in a rotary attrition mill. This process is particularly useful for the production of powdered resins for oral consumption, for example powdered cholestyramine resin, since particle sizes such that 90% by weight and/or number is below 30 microns in average particle diameter in the wet swollen state may be achieved.
