Abstract: A plate made of inorganic material comprises a support layer (1') of low thermal conductivity. Said layer is comprised of exfoliated vermiculite and a binder of compressed bodies treated at a temperature higher than 800<o>C and preferably 900<o>C, having preferably a density between 700<o>C and 1,400 kg/m<3>. The plate may be coated on one side with a ceramic layer (4) such as ceramic enamel. In an alternative for paving, the support layer (1') may be provided with a protection layer (3') of terracotta. To produce such plate, a support plate (1) is formed preferably by thickening and hardening the binder-vermiculite mixture, and the support plate is then treated at a temperature higher than 800<o>C. Simultaneously or subsequently, one of the front faces is optionally provided with a ceramic layer. The plate may be used for wall and ceiling cladding with the aim of reducing the acoustical reflection.

Abstract: Disclosed in an improved brazed implement comprising a composite compact having an abrasive particle layer bonded to a support and a substrate bonded to the support by a brazing filler metal having a liquidus substantially above 700°C disposed therebetween. In a preferred embodiment the composite compact comprises a sectioned cylindrical composite compact having a lower support surface opposite the support surface bonded to said abrasive particle layer. The composite compact also has a mating surface. The substrate about its upper end has a pocket which comprises an interior face complementary in shape with the compact lower support surface and a land complementary in shape with the compact mating surface. The compact is brazed to the substrate. The abrasive particle layer is spaced-apart from contact with the substrate a distance adequate to minimize thermal damage thereto during the brazing of the compact to the substrate. The land is of sufficient depth, however, to provide support for the compact. The preferred composite compact comprises a polycrystalline diamond compact bonded to a cemented carbide support. The preferred substrate is a cemented carbide substrate. The improved implement has special utility in drill bits for oil and gas exploration and in mining applications.

Abstract: A display assembly (Fig. l) comprises a plurality of panels (l) joined together by elongate connecting members (2, 3). Each panel has a removable frame formed by extrusions (6) in each of which is a slot (l3) having a restricted entrance (Fig. 2). Each connecting member (2, 3) has two heads (l8) which can be slid into slots (l3) in adjacent panels (l), from one end, to join the panels together, each head being too wide to pass through the restricted entrance of the slot. A central body portion (20) of the connecting member, to which the heads (l8) are joined, is positioned between, and extends outwards between, adjacent panels to facilitate access to the connecting member and enable the screen assembly to be dismantled easily. A longitudinal slot (50), (Figs. 2l to 23), can be provided in a part of the body (20) that is accessible between connected panels, to enable components such as shelf-supporting brackets to be secured to the screen assembly. To increase the versatility of the assembly, a variety of connecting members (Figs. 4 to l2) can be provided, enabling panels to be joined together in a common plane or in planes inclined to one another and in one or more tiers, and the assembly can also include panels connected together by poles (34) and clips (35) (Fig. l6). The connecting members (2, 3) can be extended components and may be of hollow cylindrical construction (Figs. l0 and ll).

Abstract: For balancing the currents to be switched off of parallel-connected gate-controlled semiconductors having different turn-off or turn-off delay times, the actual turn-off or turn-off delay times of the semiconductors (V1, V2) are first determined at low currents. Then the delivery of the turn-off signals for the individual semiconductor (V1, V2) is in each case delayed, with currents increased up to the full operating current, by the time difference, determined during the preceding turn-off process, of its turn-off or turn-off delay time to the longest-lasting turn-off or turn-off delay time of one of the parallel-connected semiconductors (V1, V2). This delay can be additionally corrected in dependence on load current. <IMAGE>

<??>They are inserted in irregular alternation at a basic width B and also at widths 1.5B and 2B. Another type of front stone is box-shaped and therefore permits planting. The anchoring (2) and connecting stones (3) form distance elements with dovetailed projections (7, 8) opposite one another of the same dimensions as the projections (5) of the front stones. By keying of the front stones (1) with these anchoring (2) and connecting stones (3), double-crowned dry walls of various thickness can be erected on the one hand, and retaining walls which can be secured in the slope by re-linking can be erected on the other hand.

Abstract: Spectral imbalance (alteration in timbre) when playing home video versions of motion pictures is overcome by re-equalization according to a unique correction response curve which compensates for the equalization for playback in large theater-sized auditoriums inherent in motion picture soundtracks. Surround-sound home playback of motion pictures is enhanced by employing main channel loudspeakers that produce generally direct sound fields and surround channel loudspeakers that produce generally diffuse sound fields. Preferably, further equalization is applied to the reproduced surround channel to compensate for the differences in perceived timbre between direct and diffuse sound fields. In addition, the reproduced surround-sound channel is further enhanced by decreasing the interaural cross-correlation of the surround-sound channel sound field at listening positions within the room, preferably by introducing slight pitch shifting in the signals applied to multiple surround loudspeakers.

Abstract: A data compression/decompression apparatus employs common circuitry and a single string table for compression and decompression. A throttle control is provided to prevent data under-runs and an optimizing start-up control delays the start-up of the recording device until the compression apparatus has compressed sufficient data to effeciently reduce throttling and loss of compression when the output device is started. The decompression apparatus may operate to decompress compressed data when the compressed data is read in either the same direction as it was recorded, or read in the direction reverse to that in which it was recorded. A further feature is the provision of a counter which is incremented by one after a predetermined number of string codes have been written into the string table. The output of the counter is stored in the string table with each string code and prefix code. When searching for an empty or usable location in the string table, the count value read from the location is compared with the count in the counter. If the two counts are not equal then the location is considered "empty" and may be written into. This arrangement avoids the usual procedure of intermittently clearing each location of the string table individually since stepping the counter is equivalent to clearing the entire table.
