Title: Mine ventilation structure
Inventor: KENNEDY JOHN M
IPC: E21F1/14
Filed: 1992-05-22
Abstract: A mine ventilation structure for installation at the intersection of first and second passageways 12, 14 in a mine defines a first passage 18 communicating with the first passageway 12 and a second passage 20 communicating with the second passageway 14. The ventilation structure includes a pair of generally parallel, spaced-apart side walls 24 defining the side walls of the first passage, and a plurality of elongate deck panels 28 extending between the side walls and forming the roof of one of the first and second passages and the floor of the other of the first and second passages. Each deck panel is a sheet metal panel generally of inverted channel shape in transverse cross section, having an upper web and side flanges extending down from the upper web at opposite sides of the web. Tie bars hold the deck panels together in fixed side-by- side relation with the side flanges of the panels closely adjacent one another so that the webs of the panels form a substantially continuous surface. <IMAGE>

Title: Strain or stress gauge
Inventor: MIYAYAMA MASARU
IPC: G01L1/22
Filed: 1992-07-27
Abstract: A strain or stress gauge 1 for measuring the stress of a structure or member and capable of recording excessive loads thereon comprises a bundle 3 of carbon or other electric conductive fibers 2, and a pair of terminals 4 for measuring the electric resistance of the bundle. The fibres may be embedded in resin 5, Fig. 2, to form a fibre-reinforced plastic (FRP) component. The component may be mounted on the surface of a member to be monitored, or embedded therein; in the latter case the component may be in the form of a grille or mesh (Fig. 9 not shown). The gauge has a simple structure, can be produced inexpensively, and its size can be chosen freely. It is possible to know not only the current strain or stress but also the history of stress in a structure or structural member since the gauge does not fully recover from high loading and its hysteresis curve can be designed accordingly. <IMAGE>

Title: Apparatus for inflating a vehicle occupant restraint
Inventor: BLUMENTHAL JACK L
IPC: B01J7/00
Filed: 1992-10-22
Abstract: An apparatus for inflating a vehicle occupant restraint includes containing means 14c for a combustible mixture of gases. An igniter 24c is activated to effect ignition of the mixture of gases in response to sudden vehicle deceleration. A directing means directs a flow of gas from the containing means into the inflatable occupant restraint. In the preferred embodiment the gases are an inert gas, a fuel gas e.g. hydrogen of methane, and an oxidizer gas e.g. oxygen. Also, a lean mixture of a fuel gas and oxidizer gas could be used. An igniter transmits energy through an imperforate portion of a wall 160 of the containing means to ignite a charge 180, 182, 206 in the containing means. The igniter may include an elongate core 204 disposed in a frangible sheath 202 which is shattered as the core is burned. <IMAGE>

Title: High-vacuum coating apparatus having a partition wall
Inventor: WENK KARL-HEINRICH
IPC: C23C14/56
Filed: 1992-12-04
Abstract: A vacuum tank in which a foil is coated in a high vacuum, is divided by a partition wall 26 into a winding chamber 27 housing a supply reel 21 and a wind-up reel 22, and a coating chamber 28 which contains a vaporizing bed 24. A coating roller 7 projects into the coating chamber.

Title: Testing a plural-channel signal processing system
Inventor: CLEMOW RICHARD DAVID
IPC: H04S7/00
Filed: 1993-06-22
Abstract: A plural-channel audio signal processing system (1), e.g. a stereophonic amplifier, is tested by means of a test apparatus (8) to determine whether the system inverts one or both channels and/or interchanges them. To this end the apparatus includes four cross-correlators (11, 12, 13, 14) which are connected between respective pairs of the inputs (2, 3) and the outputs (4, 5) of the system (1). The output of a particular cross-correlator is negative if there is inversion between the relevant system input and the relevant system output, this being indicated by means of sign-determining units (27, 28, 29, 30) and a look-up table (31). The magnitude of the output of a particular cross-correlator is higher if the relevant system input and the relevant system output carry the same channel signal then otherwise. Channel interchange is detected by comparing the sum of the magnitudes of the outputs of the two cross-correlators (11, 12) for which this is normally the case with the sum of the magnitudes of the outputs of the other two cross-correlators (13, 14). This is achieved by means of magnitude determining units (33, 34, 35, 36), adders (37, 38) and a comparator (39). <IMAGE>

Patent GB-2280576-A (GB)
Title: Speech signal encoding system
Inventor: TAGUCHI TETSU
IPC: G10L19/113
Filed: 1994-07-07
Abstract: In a speech signal encoding system comprising a maximum similarity series extracting unit (50) for producing a series of excitation pulses appearing at an equidistant time interval and an identical amplitude, the maximum similarity series extracting unit sums up, as a waveform, a series of autocorrelation coefficients to produce a series of summation result coefficients. The autocorrelation coefficients correspond to polarized pulses which are equal to one another in pulse interval and pulse amplitude. The polarized pulses form a plurality of pulse sequences which have phases different from one another. The maximum similarity series extracting unit extracts the polarity of each of the polarized pulses by the use of a dynamic programming method using the degree of accumulated similarity as an evaluation measure and selects, as the excitation pulse series, one of the pulse sequences which has a maximum waveform similarity between the summation result coefficient series and a series of cross correlation coefficients, relating to the input speech signal which is digitised at 15. A speech synthesiser for reconstructing the original speech is also disclosed. <IMAGE>

Title: Method and apparatus for continuous drying in superheated steam
Inventor: STUBBING THOMAS JOHN
IPC: F26B23/00
Filed: 1994-08-15
Abstract: Apparatus for continuous drying of moist materials 19 in superheated steam comprises a drying enclosure 10, open-ended inlet and outlet ducts 11, 12 communicating with enclosure 10, and conveyors 13, 14, 15 for conveying the material 19 along duct 11, through enclosure 10 and along duct 12. Superheated steam is generated in enclosure 10 from moisture in material 19 by circulating the initial gas within enclosure 10 between a heat source 23 and material 19, and/or by injection into enclosure 10 of superheated steam from an external source. The ducts 11 and 12 extend downwardly and a vent duct 22 extending from enclosure 10. In use, superheated steam tending to pass downwardly along ducts 10, 11 meets external air tending to pass upwardly and forms within each duct a temperature and density differential stratification layer 21 which act as barriers to the escape of steam from enclosure 10 while at the same time permitting the free conveyance of material along ducts 11, 12 and into and out of enclosure 10. The duct 22 may include a condenser to recover thermal energy from steam to preheat moist material. <IMAGE>

IPC: B44C1/14
Filed: 1995-12-21
Abstract: Several celluloid plates (5) are disposed in a vacuum container (1) of a melting/evaporating apparatus and a gold melting/evaporating device (4) is disposed in the vacuum container (1) for melting and evaporating a gold material placed therein. The above gold foil can be taken down from the celluloid plates (5) and used to manufacture a product with solid picture by means of photographical reproduction and the technique of laser sculpture or chemical etching. Alternatively, an epoxy rein or UV adhesive is added to two faces of a plastic film for adhering the gold foil or other print thereto. Then two PU films are adhered to the two faces of the plastic film to cover the gold foil or the print. Then the plastic film is lighted by ultraviolet ray to enhance the adhesion so as to form an integrated product. As an alternative to the celluloid plates a wooden or paper product may be placed in the vacuum container.
