Polyphenylene sulfide (PPS) is an organic polymer consisting of aromatic rings linked by sulfides. Synthetic fiber and textiles derived from this polymer resist chemical and thermal attack. PPS is used in filter fabric for coal boilers, papermaking felts, electrical insulation, film capacitors, specialty membranes, gaskets, and packings.
A pulse per second (PPS or 1PPS) is an electrical signal that has a width of less than one second and a sharply rising or abruptly falling edge that accurately repeats once per second. PPS signals are output by radio beacons, frequency standards , other types of precision oscillators and some GPS receivers.
The PPS-8 is an accumulator-based design with only one general purpose 8-bit processor register, A.A second 8-bit register, W, was used to buffer data for some of the accumulator instructions, but could be used for general storage otherwise.
The Rockwell PPS-4, short for "Parallel Processing System, 4-bit", was an early 4-bit microprocessor from Rockwell International, released in late 1972. Although practically unknown today, the PPS series was widely used in calculators, games and toys, and other embedded applications.
Rockwell PPS-4 in a QIP-42 package. In microelectronics, a quad in-line package (QIP or QIL), is an electronic component package with a rectangular housing and four parallel rows of electrical connecting pins. The package may be through-hole mounted to a printed circuit board (PCB) or inserted in a socket.
The PPS was usually supplied with two magazine pouches, an oil bottle, bore brush and sling. The PPS-43 was highly cost effective and easy to manufacture due to its efficient and simple, largely sheet metal design. Despite its crudeness, it has been described as controllable and reliable. [8] [9]
PPSh (left) compared to PPS (right) box magazine. As standard, each PPSh-41 came with two factory-fitted drum magazines, matched to the weapon with marked serial-numbers. If drum magazines were mixed and used with different serial-numbered PPSh-41, a loose fitting could result in poor retention and failure to feed.
The Juniper T series is a line of core routers designed and manufactured by Juniper Networks. [1] [2] The T-series core router family comprises the T320, T640, T1600, T4000, TX Matrix, and TX Matrix Plus, designed for high-end and core networks with throughput from 320 Gbit/s to 25.6 Tbit/s with a maximum forwarding rate of 30.7 billion pps.
