Patent EP-0210741-A2 (EP)
Inventor: DESYLLAS PETER LEO LAWRENCE
IPC: G01R31/3185
Filed: 1986-06-20
Abstract: A digital integrated circuit is described in which the internal registers are organised into a number of serial shift paths (12) to facilitate testing. Each path has a number of modes: USER, HOLD, SHIFT and SELF-­TEST modes. Shifting of a path is achieved by putting the path into HOLD mode and then, at each of a series of transfer pulses (TR), putting the path into shift mode for one clock beat. This allows the shifting to be performed at a lower rate than the internal clock rate of the chip; in particular, it can be performed at a rate compatible with a relatively slow diagnostic processor (11).

The fluid treatment apparatus cleaned by the method of the present invention may be a vertical tube wet oxidation treatment apparatus in which an aqueous slurry of organic materials is oxidized in a tube which extends deep into the surface of the earth. Water rinses may be performed between the steps of circulating the aqueous base solution, circulating the aqueous acid solution, and operating the fluid treatment apparatus. The water used for separating the sequential steps is preferably buffered water. The aqueous acid solution is preferably a mineral acid and most preferably nitric acid. The aqueous base solution is preferably potassium hydroxide or sodium hydroxide. The method also contemplates a sectional wash of the apparatus by directing a base or acid solution partially into the apparatus.

Abstract: A gas convection oven includes a heating chamber having a gas combustion chamber formed therein by a partition plate (120). A blower (130) is posi­tioned within the combustion chamber for circulating air through the heating and combustion chambers. The blower (130) defines a low pressure inlet centrally of the combustion chamber for receiving air from the heating chamber through a central opening (122) of the partition plate (120) and forcing it through the com­bustion chamber back into the heating chamber around the outer edges of the partition plate (120). A gas burner (138) extends into the combustion chamber and includes a distally-mounted diverter (140) for dividing and directing flame and combustion products into two different directions. A bifurcated heat exchanger (150) defines first and second tubular passages (152,154) which are aligned with and encompass the blower (130) and define inlets (152A,154A) aligned with the two different directions for receiving the combus­tion products from the burner (138). The first and second passages (152,154) terminate in a junction box (170,172) which passes the products of combustion into the low pressure inlet of the blower (130) such that air drawn from the heating chamber is mixed with the combustion products and then passed over the bifurcated heat exchanger (150) before being recirculated to the heating chamber.

Abstract: An apparatus for measuring the concentration of one material in another, such as the concentration of water in crude or refined mineral oil, comprises a conduit (14) for receiving and discharging a continuous flow stream of the fluid mixture and which is formed as part of a coaxial microwave transmission line (16, 22). A microwave or radio fre­quency range signal generator in the form of an unbuffered oscillator (30) is connected to the transmission line for generating a high frequency signal which may be varied by a voltage controlled oscillator tuning circuit (34). A signal receiver (52) monitors the change in frequency caused by impedance pulling of the oscillator due to the change in fluid dielectric constant and transmits a differential frequency signal to a frequency counter (58) and microprocessor (60) for comparison of the measured signal with known reference signals (54) for determining the percentage of one fluid mixed in the other in the flow stream. The apparatus measurement section is adapted to provide for connecting standard microwave coaxial connectors to a relatively large diameter pipe or conduit comprising the coaxial transmission line portion of the measurement section.

Abstract: 2.1 The invention is based on the object of keeping the technical expenditure for determining the approximate location of a mobile radio station low in a cellular radio telephone network. 2.2 To achieve the object, an individual base station number contained in a data message of the base station (15) is evaluated by the mobile radio station (20) and, if necessary, embedded into a voice signal to be sent out by the mobile radio station together with the subscriber number as location information. Voice signal and location information are transmitted via the base station and a line (L1) to a central evaluating station (30) which contains an evaluator (31) for the location information, that is to say the base station number and, if necessary, the subscriber number. The base station number specifies that the mobile radio station is located in the radio cell (10) of the relevant base station. 2.3 The invention is particularly suitable for the private mobile radio network C of the Federal German Post Office. 3.

Abstract: In a lawnmower (1), the lateral chassis cheeks (3) of a chassis (2), which serve for the mounting of running wheels (6), a mower shaft (8), supporting runners (7) and a sliding handle (10), each have a bearing cheek (4) receiving the wheel mounting and mower-shaft mounting and a bearing body (5) which receives in a pocket-like manner a rearwardly projecting bearing extension (17) of the bearing cheek (7) and which is pivotable about the running-wheel axis (13) for the height adjustment of the mower shaft (8) in relation to the bearing cheek (4). Not only the supporting runner (7) is mounted on the bearing bodies (5), but also the sliding handle (10) is retained on it pivotably about a tilting axis, so that the force introduced into the chassis via the sliding handle (10) during the pushing action is always applied at the same height in relation to the running plane of the chassis (2).

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.
