Abstract: A pipe fusion machine including a track mounted chassis supporting a horizontal turntable for unlimited, reversible rotation relative to the chassis. A boom pivotally attached at a rear end of, and extending forwardly of, the turntable enables manipulation of elevations and distances of the free end of the boom. The free end of the boom is adapted to permit pivotal mounting thereon of a pipe fusion tool such as an indexer configured to articulate and support a pipe-end facer and a pipe-end heater for respective independent orientation into and out of alignment with the ends of pipes to be fused. A carriage supports fixed and sliding jaws adapted to grip the ends of pipes to be fused for relative reciprocal movement during a pipe fusion process. Each of the jaws may include an upper half jaw and lower left and right quarter jaws.

Abstract: In an approach to secure firmware updating, a system comprises: one or more user devices, each of the one or more user devices having one or more firmware modules; one or more computing devices; a digital signature repository; and a z-engine circuitry. The z-engine circuitry is configured to: receive firmware for a particular user device of the one or more user devices; receive a non-repeating input data; retrieve a hardware digital profile of the particular user device from the digital signature repository; process the non-repeating input data with the hardware digital profile to generate a unique result; perform a hash operation on the unique result to generate an encryption key; encrypt the firmware for the particular user device with the encryption key; and send the encrypted firmware to the particular user device.

Abstract: A portable grasping device for gripping door handles, water faucets, toilet seats, toilet flush handles and the like which might be handled by the public and accordingly contaminated by germs is described. The device has two arms, one or both of which bear on their inner surfaces a resilient gripping material which may conform to the shape of an item being handled and which may also provide a gripping friction. The material is thick enough on the arm(s) to be compressed slightly when the device is closed, trapping within the device germs which may be transferred to the surface of the material when the device has been used. The device is releasably lockable into a locked position, and can conveniently be locked and unlocked by one hand of a user, requiring little force to use.

Abstract: A pet restraining device including a housing, a leash mechanism provided in the housing, ballast provided in the bottom portion of the housing such that the pet restraining device has a center of gravity that is nearer to the bottom portion of the housing than to the top portion of the housing, and filling material provided in the housing to fill the spaces and secure elements of the device together. A method of making a pet restraining device including providing a housing, providing a leash mechanism in the housing, providing ballast in the bottom portion of the housing to produce a low center of gravity of the housing, and providing filling material in the housing to fill the spaces and secure elements of the device together.

Abstract: A system for dispensing substances into a room of a building comprises at least one reservoirs, at least one nozzle, at least one pump, and logic. The reservoir contains a substance to be dispensed into the room, and the pump is coupled to the nozzle and the reservoir. The logic is configured to enable a user to select, for dispensing through the nozzle, the substances from the reservoir, and the nozzle is positioned within the building such that the substance dispensed from the nozzle passes into the room. In some embodiments, the nozzle is positioned within a duct of a heating, ventilated and air conditioning (HVAC) system.

Abstract: An inverse assembler that uses a memory map as a substitute for some microprocessor status signals. This reduces the number of signals needed from a microprocessor to perform disassembly.

Abstract: An inverse assembler that uses a memory map, the stored trace signals and the load and store architecture of a microprocessor to reconstruct microprocessor signals. This reduces the number of signals needed from a microprocessor to perform disassembly.

Abstract: A process for removing ethylene oxide from a gas composition containing ethylene oxide by intimately contacting the gas composition with an aqueous acidic solution and having a pH less than about 4 and an initial temperature less than about 50.degree. C when the solution comprises the minimum volume required to substantially completely convert the ethylene oxide. The initial pH and temperature of the solution and the initial mole ratio of acid in solution to ethylene oxide being converted is controlled to permit substantially complete conversion of ethylene oxide to products including ethylene glycol and polyethylene glycols while preventing evolution of dissolved ethylene oxide from solution. During reaction, the solution temperature is maintained less than about 70.degree. C to avoid evolution of dissolved ethylene oxide.
