Granted: 1982-08-24
Abstract: ABSTRACT OF THE DISCLOSURE         This invention is directed to a copolycarbonate of a polycarbonate of a trityldiol such as phenolphthalein and a polycarbonate of another diol such as bisphenol-A and to a process for preparing the copolycarbonate.  The copolycarbonate is prepared by contacting the starting polycarbonates under conditions of shear and/or temperature sufficient to cause reaction of the polycarbonates to form a copolycarbonate of the polycarbonates.  The copoly-carbonates of this invention exhibit generally improved impact resistance, clarity and flame resistance as compared with the starting polycarbonates or with a copolycarbonate from polycarbonate copolymers of the same diols.  Applications of particular interest for the utilization of the copolycarbonates of this invention are in aircraft parts and automobile parts requiring higher heat resistance than possessed by the homopolymers of bisphenol-A and similar diols.

Title: Method and apparatus for testing metal tapes
Inventor: WEISCHEDEL HERBERT R
IPC: G01R33/12
Filed: 1979-11-13
Granted: 1983-07-05
Abstract: METHOD AND APPARATUS FOR TESTING METAL TAPES     ABSTRACT    Magnetic flux is induced in the tape by applying a magnetic field to the tape.  Where there is a perforation or a crack air gaps are created and magnetic flux radiates outwardly from the tape across these air gaps.  The presence of the crack is detected by sensing the radiating flux at two distances from the tape.  At one distance, close to the tape, the total flux is the sum of the flux from the crack and the perforation.  At the other distance, further from the tape, the flux is solely that produced by the perforation.  A coil is placed at each position to sense the flux.  The tape is moved, which causes the flux to intersect the coils.  The intersection produces an output signal from each coil.  The signal produced by the coil further from the tape is subtracted from the signal produced by the coil closer to the tape; the difference being a signal caused by the additional flux produced by the crack.  An alarm is sounded and in indicator lights when the signal is present.

Abstract: ABSTRACT The present invention relates to a process for preserving wood, in particular hardwoods, against attack by living organisms, e.g. fungi and insects, which destroy wood. In particular, the present invention provides a one or two step pro-cess for preserving wood against fungal and/or insect attack.  The fungicide treatment step comprises introducing a copper solution or a copper and arsenic solution into wood.  me insecticide treatment step comprises introducing a chromium and arsenic solution into wood.  If the pH of the wood system is controlled, both steps may be carried out simultaneously so as to preserve the wood against fungal and insect attack.  Alternatively, the insecticide treatment step may follow the fungicide treatment.  Where only protection against fungus is desired, the process comprises introducing copper and arsenic solution into wood.  On the other hand, if only an insecticide treatment is required, the process comprises only the above mentioned insecticide treatment step.  The process according to the present invention can be successfully used to treat wood which has been difficult to treat using conventional methods.

Title: Pressure flow compensated hydraulic priority system  providing signals controlling priority valve

Abstract: PRESSURE FLOW COMPENSATED HYDRAULIC  PRIORITY SYSTEM PROVIDING SIGNALS  CONTROLLING PRIORITY VALVE           ABSTRACT OF THE DISCLOSURE           Priority valve system with pressure-flow compensation and signal control having first, a restricted orifice which can be satisfied when flow requirements therethrough are sufficiently large in combination with, second, a closed center primary control valve equipped with an hydraulic detent unlatch mech-anism and hydraulically disposed downstream of the orifice to receive the flow directed thereto by the orifice, all to provide appropriate signals controlling the priority valve.  Through this intervening, novel two component control combination, the priority valve is controlled to supply flow to a priority load and, in addition, has an auxiliary outlet chamber connected to an auxiliary motor with the purpose to cut off the auxiliary chamber flow whenever the priority flow is sufficient to satisfy only the restricted orifice.  A signal line to the priority valve will, when fed with a pressure signal, coase the cut-off but, when vented to drain, will open the auxiliar chamber. Because the primary valve in a detented operating position thereof provides a connection between the downstream orifice pressure and the hydraulic unlatch mechanism, and in a reset neutral position provides a switch-over function disconnecting the signal line from downstream pressure and reconnecting it with a vent to drain, the primary valve during any priority load stall-out which causes the orifice to become unsatisfied, will automatically reset itself and cause the priority valve to open the auxiliary outlet chamber to the auxiliary motor even though there is no flow in the stall-out priority flow path.

Abstract: FUEL CONTROL SYSTEM FOR A DUAL-FUELED POWER UNIT               Abstract of the Disclosure A turbo-charged, inter cooled governed speed diesel engine directly coupled to an alternator for electrical generation is adapted for dual-fuel operation and mounted on a trailer which also supports the engine's fuel sources including diesel fuel in a conventional tank.  The second fuel is producer gas generated in a down draft continuously operating producer of the moving-packed-bed vertical flow reactor type with co-current gas flow.          Solid waste such as crop residues, e.g., corn cobs, is used as fuel stock for the producer and is conveyed automatically to the producer from a bin on the trailer.  Before delivery to the air intake of the diesel engine the producer gas is conditioned by passing it through a cyclone and filter to remove solid particu-late matter and a cooler-condenser for cooling the gas and con-densing out tars.  The diesel governor and fuel pump assembly is modified only by the application of a fuel rack stop for maintain-ing a pilot flow of diesel fuel and the engine control system is such that the response of the diesel injection system to changes in engine load is normal in general; however, automatic controls are provided for monitoring diesel pump fuel rack position and engine load so that after engine loading is increased a throttle valve in the gas supply to the engine is progressively and rela-tively slowly opened tending to increase engine speed so that the diesel injection rate is conventionally cut back correspondingly until an equilibrium condition is reached in which engine fuel demand in excess of the pilot minimum diesel fuel flow required to maintain combustion is provided by producer gas.  The response of the system to a decrease of engine loading when the engine is operating at minimum diesel fuel flow (that is with the fuel rack stop effective) is to reduce fuel supply rapidly and appropriately by partially closing the gas throttle valve.  Automatic safety shutdown provisions include, in at least one shutdown mode, delayed shutting off diesel fuel flow following producer gas shutoff so that the engine and exhaust system are purged of producer gas so as to reduce explosion hazards.

Abstract: 16. ACCELERATED PARTICLE LITHOGRAPHIC PROCESSING    AND ARTICLES SO PRODUCED       Abstract of the Disclosure Ion beam lithography of particular interest in the fabrication of large-scale integrated circuits of unexpectedly increased throughput results from appropriate choice of (a) resist material and (b) ion species.  Resist material, generally negative acting, is characterized by electron beam sensitivity inadequate for ordinary commercial electron beam lithography.  The relevant characteristic responsible for inadequate electron beam sensitivity is the very characteristic responsible for enhanced ion sensitivity.  Ion species, always of atomic number greater than that of proton, are dictated by the observation that sensitivity unexpectedly increases at a greater rate than predictable on traditional bases.

Abstract: TWO-PHASE THERMAL ENERGY CONVERSION SYSTEM           Abstract A two-phase thermal energy conversion system employs an evaporable liquid, such as water, and a gas which is not liquefiable within the operating temperature and pressure ranges, such as air.          The water and air are mixed and one of the two or both are heated so that the water evaporates and is absorbed by the air to result in a pressure increase.  The increase of pressure or volume can be converted into mechanical energy by a prime mover such as a turbine or reciprocating piston engine.  The heat of condensation is utilized and converted into mechanical power while the temperature and pressure are reduced.  The liquid, such as water, may be below its boiling point.  If the water consists of salt water, fresh water is derived as a condensation product from the prime mover.

Abstract: ABSTRACT OF THE DISCLOSURE         A jig for assembling table tops such as picnic table tops, which have a plurality of similar elongated rectangular top members secured together in aligned fashion on transverse bottom members.          The jig comprises a frame to which are secured transverse member holders having bottom and side surfaces to receive and secure in parallel position at predetermined spaced locations the transverse members in such a way that that the upper surfaces of the transverse members in position in the transverse member holders lie in the same plane.  The jig also comprises alignment means secured to the frame to align one end of the top members when in assembly position on the transverse members in the transverse member holders.  An alignment means is rigidly secured to the frame at a position which will properly orient a top member with respect to the transverse member by abutment of one of the top member's side surfaces against this alignment means.  In instances where spaced top members are required for the table, spacer pins are provided of a diameter similar to the desired spacing between adjacent top members.  These pins are laterally moveable in channels secured to the frame so that a pin is received towards each end between the sides of each pair of adjacent top members.  The jig is provided with a pair of clamping jaws movable laterally in the assembly plane of the top members and means to move the clamping jaws to bear against the outer sides of the outer top members and to move the top members transversely into final assembly position and hold them in that position for assembly.  The jig according to the present invention partially automates what has previously been a strictly manual job of aligning and securing top table members to transverse members.
