Abstract: A pressure diffuser (10) includes in a liquid-tight pressurized vessel (12) a vertical screen (24) which defines with a vessel wall (14) first and second interior volumes (26, 29) for transmitting pulp from a pulp inlet to a pulp outlet and receiving displacement (e.g. wash or bleach) liquid transmitted from headers (28) through the pulp. The screen ends around housing members (20, 22) have different cross-sectional areas, and quick movement of the screen effects backflushing. The volumes (26, 29) are segregated by the vertical, generally cylindrical, screen (24). A chamber (42) is provided in communication on opposite sides of a piston (44) therein with the pulp adjacent the pulp inlet (16), and the extracted liquid (in 29). By displacing the piston with a cylinder (50) immediately prior to rapidly moving the screen vertically with a hydraulic cylinder (50) to effect backflushing through the screen, the pulp pressure on the screen is reduced and at the same time shocks and compaction of the pulp adjacent the inlet caused by the movement of the screen are avoided.

Abstract: A heat-recoverable wrap-around sleeve for pipe protection, with a patch-type closure. 
     The patch is heat-stable and comprises two polymeric layers (4,6) bonded together through, for example, an open mesh glass-fibre fabric (8). No separate adhesive is required. 
     The hot modulus of one of the layers is low enough to enable it to bond to the overlapping edges of the wrap-around sleeve, and the hot modulus of the other layer is high enough to withstand installation temperature. 
     This new patch is easier to install and requires less materials than prior art patches, and does not need to be bonded to the sleeve in such a distinct heating step.

Abstract: A horn radiator assembly (10) includes two horn radiators (12, 14) each of which is formed as a conical horn and a waveguide of constant cross section connected to the small end of the horn as a feed and providing a signal port. The first of the horn radiators (12) is of relatively large cross section and serves to radiate electromagnetic waves at a relatively low frequency. The second of the horn radiators (14) is of relatively small cross section and serves to radiate electromagnetic waves at a relatively high frequency. The second radiator (14) is nested within the first radiator (12), and is positioned with its radiating aperture (28) coplanar with the radiating aperture (20) of the first radiator (12). In the second radiator (14), the waveguide feed (26) is provided with a bend (36) allowing the waveguide feed to pass through a wall (32) of the first radiator (12). A strut (34) may be affixed to the bend (36) to provide a symmetrical transverse support within the first radiator for the second radiator. A doubly-tapered electrically conductive sheet (48) extends from an apex within the throat (18) of the first radiator horn (12) to the transverse support, and from there tapers back to contact the horn of the second radiator (14). The tapered sheet (48) guides low-frequency radiation past the strut (34) and the bend (36) to minimize standing wave ratio.

Abstract: A smoking article (10) includes a short, combustible, carbonaceous fuel element (12) in a heat exchange relationship with a substrate (20) carrying glycerin, tobacco extract, and a portion of an essential oil gland bearing plant. For example, fragments of cinnamon bark, lovage root, chamomile flowers or cardamon physically separate from the fuel element provide for a controlled release of a flavor profile during use of the smoking article. Heat provided by the burning fuel element acts to release essential oils from the glands to provide a complex flavor and aroma profile. The smoking article is capable of providing the user with many of the pleasures of smoking by heating but not necessarily burning tobacco.

Abstract: The device comprises a conditioning part fitted with a mixing vessel, which serves for intimate mixing of sludge and a conditioning agent, and a pump part, connected by lines to the mixing vessel and to a chamber filter press, for delivering the conditioned sludges from the mixing vessel to the chamber filter press and for subsequent pressing of the sludges in the chamber filter press. The pump part comprises at least two reciprocating pumps which are driven essentially in opposite directions and are connected to a common delivery line. The pump drives are also controlled in such a way that the delivery stroke of one pump always starts before the other pump has finished its delivery stroke. This results in an essentially constant pressure level downstream of the pumps, because the pressure stroke, initiated with an advance, of one pump in each case is effective before the other pump has reached the outer dead centre. <IMAGE>

Abstract: An electronic dictionary apparatus designed to dis­play equivalent words, related words, etc. for an input word comprises first and second dictionary memories (17, 18). Entries in the first dictionary memory (17) are of the first language, and entries in the second dictionary memory (18) are of the second language. Equivalent word information of each entry of one language is positional information of an equivalent word of the other language stored as an entry of the other dictionary memory. This dictionary memory configuration can prevents redundant storage of a word and thus prevents the dictionary memo­ries from becoming large.

Abstract: There is provided a method for making diamond and CBN compacts which comprises positioning a catalyst metal disc (2) and a barrier disc (3) intermediate a diamond or CBN mass (1) and a carbide mass (4). The catalyst metal disc is adjacent to the diamond or CBN layer and the barrier disc is intermediate said catalyst disc and the carbide mass. In order to prevent unregulated flow of metal bond from said carbide mass to the diamond layer and to prevent depletion of metal bond from the carbide near the carbide/diamond interface, the barrier disc has a surface area virtually identical to that of the carbide mass. Such arrangement of materials is subjected to temperature and pressure conditions within the diamond stable region but below the melting point of the barrier disc.

Abstract: Disclosure is given for methods of effectively forming a metal-backed layer and an anode using a metal film transferring sheet in which micro-holes are formed. A the metal film transferring sheet is structured by forming a metal film on a mold-releasable, highly characteristic sheet. Then, the metal film having micro-holes of the metal film transferring sheet is transferred onto a phosphor screen. Or, on the metal film of the above-mentioned metal film transferring sheet is formed a phosphor screen and these metal film, phosphor screen, etc. are collectively transferred onto a face plate thereby to form an anode of a cathode-ray tube. Then the disclosed methods are applied for making phosphor products for example, a cathode-ray tube or a plasma display. There is no need to use a large-scaled manufacturing facility and high quality, low-in-cost products are obtainable.

Abstract: A biosensor which can be used for continuous monitoring of biological, biochemical or chemical reactions in which an alternating electrical potential is applied to effect the alternate capture and release of polarisable entities within the sample. There are two basic methods of achieving this, one shown in the attached drawing which shows an SPR (surface plasmon resonance) biosensor in which a sample flowing across a spot (9) of sensitive material in the direction of arrow (A) is subject to an alternating electric field in the area of the reaction (if any) between the sample and the sensitive material. The electric field is generated by applying an alternating potential from a source (12) across the area of the reaction, using an electrode (11).

Abstract: A receiver processes an NMR signal to produce a baseband image information signal from which two quadrature component signals are derived. An intermediate frequency section mixes (303, 306) the received NMR signal with two reference signals (201, 204) to shift the image information into a frequency band having a bandwidth BW and centered at a frequency that is 1:5 times the bandwidth BW. The resultant signal is filtered (308) to remove extraneous signals outside the image information band. An analog to digital converter (209) samples the filtered signal at a rate that is twice the bandwidth Bw and digitizes the samples into a digital signal. A quadrature detector (210) derives I and Q output signals from the digital signal by alternately selecting (311, 321) digital samples and negating every other sample selected for each of the I and Q output signals. The quadrature detector also digitally filters (312, 322) the I and Q signals which are then used to construct an NMR image.
