Abstract: ABSTRACT OF THE DISCLOSURE:          A linear accelerator for charged particles is constructed of a plurality of transmission line sections that extend between a power injection region and an accelerating region.  Each line section is constructed of spaced plate-like conductors and is coupled to an accelerating gap located at the accelerating region. Each gap is formed between a pair of apertured elec-trodes, with all of the electrode apertures being aligned along a particle accelerating path.  The ac-celerating gaps are arranged in series, and at the injection region the line sections are connected in parallel.  At the injection region a power pulse is applied simultaneously to all line sections.  The line sections are graduated in length so that the pulse reaches the gaps in a coordinated sequence whereby pulse energy is applied to particles as they reach each of the gaps along the accelerating path.

Abstract: ABSTRACT An apparatus and method for using a test window to improve the efficiency of clipping and inter-coordinate images which are to be displayed by a graphic display subsystem. A test window is defined which surrounds a window (the clip window) within which it is desired to render graphical images. Objects are then tested to see if their vertices are outside the test window. The utilization of this test window allows for a performance optimization to be made between processing of a clipped object by a hardware based graphics subsystem which incorporates the present invention or by graphics software executed by a general purpose CPU which also interfaces to the graphics display. By properly defining the test window size relative to the clip window, objects which fall totally within the test window, will be rendered faster by the graphics subsystem rather than deferring the object to graphics software. Objects with vertices that fall outside the test window would be deferred to graphics software to render.

Abstract: An solid-state electricity meter includes an electronic measuring unit with an analog/digital converter which receives signals from amplifiers for various measurement ranges, and a control section with a microcomputer wherein the meter signal is processed, taking into account correction factors for the various elements of the circuit. Each correction factor is a single value for each respective measurement range, and the correction factors for each range are contained in corresponding meter-characteristic quantities which are stored in the electricity meter. Each meter-characteristic quantity represents a measurement value corresponding to a specific quantity of energy. Only a few (e.g., only 4) meter-characteristic quantities need be stored in the electricity meter. These meter-characteristic quantitites can be determined in a conventional calibration procedure, and they enable all the fixed errors of the signal processing to be compensated.

IPC: H04L49/111

Abstract: Data containing traffic volume statistics are preferably transmitted in packet form with packets of equal length via virtual links. In a packet switching device, it is essentially possible that two or more packets may arrive simultaneously from different lines but are intended to be forwarded along the same line. 
<??>For this reason, buffer memories must be provided, in which the packets which cannot be forwarded immediately are queued. The memory capacity required for this purpose depends not only on the length of the packets but in particular on the number of converging lines, the type of traffic volume and the transmission quality required. In known packet switching devices, around 80% of all the chip surfaces are used within the switching network for these memories. 
<??>According to the invention, a fixed number of packets are combined within the exchange in each case to form a frame, all packets are divided into packet parts of equal length and are distributed among sub-frames. Switching is carried out on the basis of sub-frames using synchronous time-division multiplexing. The memory space required in the switching network is reduced by the frame : sub-frame ratio. The memories used are those which are required in any case for synchronous time-division multiplex switching.

Abstract: A flexible and equitable PCN/PSTN interconnection strategy between a communications network having mobile subscribers, such as a PCN network, and a PSTN whereby to form a communication system in which multiple tariffs can be applied, the tariff applied being determined by the actual location of the mobile subscriber involved in a call. The PSTN (2, 6, 9, 10) is not given total access to the PCN (1, 5, 8, 11) location registers, rather a PSTN to PCN call is via a PCN gateway (5) which does have access to the location registers. The gateway (5) accepts zonal calls with which are associated one tariff (zonal interconnect 4) but for, for example, local or interzonal calls, it provides drop back messages to the PSTN to arrange for appropriate rerouting to other gateways (1, 8) of the PCN which have different tariffs associated therewith (local interconnect 3, interzonal interconnect 7) (Fig 2). <IMAGE>
