  • Patent number: 5433377
    Abstract: An electrical interlock ties a heat recover ventilator to circulation air blower operation of an associated forced-air furnace or air conditioning system. This ensure that the blower circulates supply and return air within the building or dwelling. An interlock relay has its coil energized by the heat recovery ventilator, and a normally open contact tied to the control of a blower of the forced-air system. The furnace or air conditioner and the ventilator are operated by separate controls located within the building's comfort space. When the ventilator is operated, the circulation blower runs continuously, but thermostat actuate of the furnace or air conditioner above will not operate the ventilator.

  • Patent number: 5379859
    Abstract: A scaffold support assembly comprises a support subassembly, a brace subassembly and a position adjustment subassembly. The support subassembly includes a longitudinal base member and a stabilizer member attached in transverse relation to and extending in opposite directions laterally from the longitudinal base member. Both the base and stabilizer members are adapted to lie flat on the roof. The brace subassembly includes vertical and horizontal members and an elongated flexible member. The vertical and horizontal members are connected at adjacent ends to the base member and pivotally movable relative thereto. The elongated flexible member extends between and interconnects remote ends of the vertical and horizontal members such that the elongated flexible member and vertical and horizontal members are arranged in a right trianglar-shaped configuration. The position adjustment subassembly includes a brace, a bracket, and a fastening element. The brace is rigidly attached to the base member.

  • Patent number: 5370570
    Abstract: An improved portable mobile toy having at least one element attached to and suspended from an umbrella structure with an improved support system to which the umbrella structure is rotatably attached. The improvement comprises a clamping assembly which is adaptable and adjustable for attaching to a variety of fixtures such as chairs, tables, car windows, as well as to cribs and playpens. The support system includes a pair of beams which are connected to the clamping assembly. The beams are so connected to permit rotation and pivoting about the clamping assembly. The two beams are rotatable relative to each other and when in the selected relative position they are clamped so that they do not then move relative to each other. One of the pair of beams may be lengthwise adjustable and may be used by itself; that is, one end attaches to the umbrella portion and the other end to the clamping assembly.

  • Patent number: 5339428
    Abstract: A compiler includes a register allocation method making use of the concept of assigning temporary items to lifetime holes if such holes exist that are suitable. The compiler includes a front end for converting the input code to an intermediate representation, then this input representation is traversed to identify all of the temporary items, and to find all of the holes in the temporary items. Lists are maintained of the identified temporaries and holes. Register allocation then includes assigning temporaries to registers so long as there are free registers, and if holes are available in already-assigned temporaries then these holes are used in assigning registers. After all the available registers and holes are used, remaining temporaries are unallocated and thus represent memory references.

  • Patent number: 5270728
    Abstract: A method for multiplying the speed-resolution product of a raster scanning or imaging device such as an inkjet printer, and a resulting pixel image data structure, are disclosed. Illustratively, a 300-dot per inch (dpi) by 600-dpi logical pixel image is mapped to a corresponding, non-overlapping physical dot image, and the printer's inkjets are fired responsive to the dot image to direct generally spherical ink droplets onto paper at 600-dpi resolution grid timing in order effectively to double the horizontal resolution of the printed pixel image, without increasing the firing rate of the print head. In order to accomplish this, and to avoid ink dot overlap, the printable pixel image is thinned before it is printed by a method that leaves no visible horizontal or vertical gaps by selectively turning off pixels within a `black` image that were on and that otherwise would result in ink dot overlap and slower print head speeds were the inkjets cycled at 600-dpi resolution timing.

  • Patent number: 5265176
    Abstract: A method is disclosed of mapping raster data input of a source data set to a destination data set, wherein the source and destination data sets have different resolutions. Initially, a resolution ratio is determined between the source data set and the destination data set. The horizontal component of the source data set is converted to the resolution of the destination data set by copying select discrete groups of the source data to form a desired number of discrete groups of the destination data. A select number of vertical, or raster, rows of the horizontally converted data set are copied to form a required number of rows, thereby completing the destination data set. Look-up tables are provided to efficiently convert the horizontal component of the source data set. An apparatus for mapping raster data input includes a computation mechanism for determining the resolution ratio, and mechanisms for converting the horizontal and vertical components of the source data set into the destination data set.

  • Patent number: 5197138
    Abstract: Save-Exception-State and Restore-Exception-State primitives are defined in the operating system and are used to confine the reporting of delayed asynchronous coprocessor exceptions to the respective code threads that generate the exceptions. The Save-Exception-State primitive saves the coprocessor exception state pertinent to the currently executed code thread, and the Restore-Exception-State primitive restores a selected one of the exception states having been saved. The Save-Exception-State primitive synchronizes the coprocessor, disables use of the coprocessor, saves any pending coprocessor exception state into memory, and clears the coprocessor exception state information from the coprocessor or a "thread descriptor" area of memory allocated to the current code thread.

  • Patent number: 5178239
    Abstract: A shock absorber includes an extruded reservoir housing and a sleeve with position valving therein. The shock absorber coordinates the position valving and valving in the piston assembly in a manner such that the position of the piston assembly relative to the position valving becomes a factor in determining changes in valving.

  • Patent number: 5172547
    Abstract: A controlled fuel flow system from variable flow solid fuel gas generator to secondary combustor is provided, which system includes a hot gas valve which is operated by an electronic controller. The valve is mounted between the gas generator and the secondary combustor, which valve has in the throat thereof a pivotable blade that moves to relatively blocking and unblocking positions therein and a nozzle downstream of such blade which communicates with the secondary combustor. A first pressure transducer is mounted in the gas generator and a second pressure transducer is mounted downstream of such blade near or in the nozzle. Actuator means are also provided to pivot such blade between relatively blocked and unblocked settings as guided by electronic gas flow controller logic. The secondary combustor has one or more air ducts therein and the above system is mounted, e.g., in a variable flow ducted rocket.

  • Patent number: 5127903
    Abstract: This is a device for delivering medicaments to infants by means of a dispenser in a pacifier. The dispenser regulates the rate of medicament released by using semipermeable membranes or capillary tubes. As the child or infant suckles on the pacifier, a flow of saliva bathes the dispenser and mixes with the dispensed medicaments.

  • Patent number: 5060286
    Abstract: The invented graphics images data compression method includes software which selectively compresses data on a raster-row-by-raster-row basis or on a byte-group-by-byte-group basis. The raster-row-by-raster-row basis compares bytes within adjacent raster rows and thereby detects repetitions between the rows. When data is compared on a raster-row-by-raster-row basis, the invented method records any differences as relative offset and replacement bytes. The byte-group-by-byte-group basis compares different byte groups within a single raster row, and thereby detects repetitions within the row itself.
