Title: Process and apparatus for manufacturing single  piece railroad ties of prestressed concrete
Inventor: MARCHESI SERGIO
IPC: B28B21/78
Filed: 1978-04-14
Granted: 1981-12-22
Abstract: ABSTRACT           A process and apparatus are disclosed for produc-tion casting of railroad ties and the like to obtain maximum mold utility.  The casting is accomplished by arranging tendons within a mold and subjecting them to an appropriate tensile stress.  Uncured concrete is then introduced at a temperature of around 80°C - 90°C.  The mold is vibrated and subsequently closed.  It is then maintained at 60°C -80°C for a time sufficient to cure the concrete such that the prestressing mechnism can be released.  The mold may then be immediately re-used.  One mechanism by which the molds may be closed during the curing process in a most efficient manner is to employ succeeding molds in a stacked arrangement to cover each preceding mold cavity.  A single piece conical locking member is also employed to anchor the tendon in the mold.

Abstract: Abstract of the Disclosure Apparatus and method for the counting of objects and in particular fruits such as oranges, grapefruit, lemons, and the like, which are randomly continuously presented by a conveyor or other means to a counting area in which the objects are illuminated. An image of the counting area and illuminated objects is optically reproduced on a self-scanning photodiode array which generates a series of output analog video signals corresponding to the light intensity on each of the photodiodes. These analog signals are amplified and compared with a voltage that is approximately 60% of the peak voltage value from the array, to provide an output binary signal pulse having a digital logic value of "1", when the video signal is above the 60% value, and a value of "0" when below the 60% value. Logic circuits group certain of the output binary signal pulses into a predetermined group recognition pattern having a configuration such that it will occur only once for each object that it scanned, and which is decoded to provide an output counting pulse for each object presented to the counting area.

Abstract: 986.013 Title:  COMPOSITION AND METHOD FOR CONTROLLING   VOLUME IN FILLED RESINOUS SYSTEMS             Inventor:  JOHN A. HEINEN              ABSTRACT OF THE DISCLOSURE            Shrinkage occurring in filled resinous systems prior to set can be controlled by incorporating therein certain blowing agents of the type that normally generate gas as a consequence of thermal decomposition, and/or activators for such agents, in the filled resinous system and causing a comparative positive volume change in the system without the application of external heat to the system and without the development of any significant exothermic heat.  Thus, selected additive chemical blowing agents generate gas in the filled resinous system to affect its volume, with or without the presence of activators, although maximum exotherms recorded are far below the lowest heat decomposition requirements of the conventional blowing agents utilized and no external heat is applied.  Certain selected known activating agents for chemical blowing agents when used alone without the blowing agent have also shown unexpected abilities to affect the volume of filled resinous systems.  The additive agents may be blended with the fillers for the resinous material in varying amounts to achieve a reduction or elimination of shrinkage or to expand the filled system.  Epoxy grouts and mortars incorporating various selected blowing agents with or without activators are exemplary.

Abstract: ABSTRACT OF THE DISCLOSURE         The gap between the print head and the printing surface or platen in a printer is extremely critical in certain types of printers.  Where printers are required to accept print media of various thicknesses (single or multipart paper), an adjust mechanism is required to optimize the print gap.  A problem arises thereafter whenever ribbon has to be changed or new paper fed into the printer, since the print head must be retracted from its optimum gap position  for ease of operation.  The present invention provides for automatically resetting the print head to its predetermined previous gap spacing following movement of the print head away from the printing surface for servicing such as paper loading or ribbon replacement.  This is accomplished by providing a lever, adapted to move the print head away from the printing surface, with a cam face for mating with a cam follower carried by a gap adjustment arm pivoted for movement in fixed distance increments about a pivot point.  The movable arm serves as a memory for recording the previous print head gap spacing as well as providing extremely fine control for moving the print head in fine, fixed distance increments corresponding to the incremental distance movements of the movable arm.

Abstract: ABSTRACT OF THE INVENTION           The resolution of an image that is produced by a graphic recorder is related to the rate that recording paper passes through a recording zone and the sweep rate is related to the rate at which a scanning electrode contacts the recording paper.  According to the present invention, both the sweep rate and the resolution are simultaneously coordinated through the use of a ratchet wheel and pawl that are interconnected between the scanning electrode and feed rolls.  The ratchet wheel is indexed through the movement of the scanning electrode and as the scanning electrode makes a sweep, the feed rolls are indexed by successive or multiply successive teeth in the ratchet wheel.  An anti-backlash device is wheel and the feed rolls from reversing themselves during operation of the recorder.

Abstract: BACKWATER VALVE                        ABSTRACT        A check valve insert for installation between the inlet and outlet ports of a conventional "T" pipe coupling.  The insert comprises a coupler for insertion into the coupling inlet port, a guide sleeve affixed to the coupler to project into the conduit, and a check ball positioned within the guide sleeve.          The coupler includes a valve seat against which the check ball may rest to prevent fluid passage from the coupling outlet port to its inlet port.  A plurality of apertures are spaced around the upper end of the guide sleeve above the coupling outlet port.  Fluid outside the conduit which rises above the check ball enters the coupling inlet port and eventually lifts the ball away from the valve seat.  The fluid passes up into the guide sleeve to flow through the apertures and exit via the coupling outlet port.  Sufficient clearance is provided between the check ball and the guide sleeve to prevent lodging therebetween of for-eign particulate matter which might jam the check ball.  The components of the insert are designed to inhibit accumulation of foreign particulate matter which might interfere with movement of the check ball or sealing engagement thereof with the valve seat.          The insert is also fashioned to facilitate cleaning without requiring removal of the insert from the cou-pling.
