Title: Digital oscillators for musical sound reproduction
Inventor: LYNCH MICHAEL R
IPC: G10H7/00
Filed: 1987-11-25
Abstract: A digital oscillator (8) accesses samples stored in a RAM (2) representing a sound to be played. The required output samples are produced by a process of interpolation taking into consideration the pitch factor at which the sound is to be played. The digital processing has the effect of low-pass filtering the sound signal played with the required pitch factor and re-sampled at a second, fixed sampling frequency, which is independent of the pitch factor. The output samples are fed to a digital-to-analogue converter (18) and finally to a fixed cut-off frequency low-pass anti-aliasing filter (20). <IMAGE>

Patent GB-2214534-A (GB)
Title: Jet dyeing machine
Inventor: LIN CHING-CHUAN
IPC: D06B3/28
Filed: 1988-01-21
Abstract: A dyeing machine is provided with two valves and which selectively direct dyeing liquid through either a high pressure jet nozzle (701) or through a low pressure nozzle (702). Piece goods (not shown) are circulated in a closed path through the appropriate nozzle. The-high pressure nozzle is selected for dyeing long fiber cloth and the low pressure nozzle is selected for dyeing short fiber cloth. As a result, it becomes easier to control the machine to dye piece goods of different characteristics in a satisfactory manner. The two nozzles open into an elongate chamber of relative wide cross section, the cross section of the chamber increasing gradually away from the nozzles. <IMAGE>

Title: Continuous mining machine having dust collection system
Inventor: LEBEGUE MAURICE K
IPC: E21C35/22
Filed: 1990-03-19
Abstract: A self-propelled continuous mining machine includes a mobile frame assembly (12) having a boom assembly (22) pivotally retained thereon. A dust collecting system (42) is positioned on the mobile frame assembly for inducing a flow of air through a hollow interior portion of the boom assembly. As a dislodging head (30) removes material from a mine face, the dust collecting system allows airborne dust created by the dislodging head to be drawn through a hollow interior of the boom assembly and into the collecting system mounted on the mobile frame assembly in any preselected position of the boom assembly. A first duct assembly (47) runs longitudinally along the one side of the frame assembly and a second duct assembly (90) turns longitudinally along the other side of the frame assembly to a transverse cross-over portion (92). A conveying system mounted on the mobile frame assembly receives material from the dislodging head and transports the material rearwardly of the machine. The transverse cross-over portion (92) crosses to the other side of the mobile frame by passing between the conveying reach and the return reach of the conveying system and joins with the other duct so that a single fan may be used to draw airborne dust through the system. In another embodiment the duct assembly runs along one side of the frame assembly. <IMAGE>
Patent GB-2232543-A (GB)
Title: Fluorescent lamp dimming system
Inventor: JURELL SCOTT R
IPC: H05B41/392
Filed: 1990-03-29
Abstract: A circuit 21, 23 applies to lamp 34 a time varying first current that is adjustable for lamp dimming, and a circuit 25, 27, 29, 31 provides a second current to sustain the discharge in which the first current alone is insufficient. Dimming may be achieved by phase control, reverse phase control, notch phase control, use of a PWM d.c. chopper, or an adjustable autotransformer and the sustaining second current may be applied continuously or only during off periods of the first current. The second current and heating current to lamp filaments 35, 35' may be d.c. or at line frequency, but more particularly is at high frequency produced by frequency converters 29, 39 and transformers 31, 37 or by one converter and one transformer (Figs 7, 8). A circuit (117), (121), (Fig 6), may disable the converter 39 if excess current is sensed. H.F. discharge sustaining current may be provided via an LC resonant circuit (223), (225), (Fig 8), (333), (335) (Fig 11), which is also operative prior to lamp starting to provide high voltage to strike the lamp. Starting may be achieved by applying high frequency to strike a low level glow current while simultaneously applying a line frequency voltage below the Townsend glow-transition voltage (VI), (Fig 10). A circuit (337), (339), (Fig 11) may respond to excess voltage in the resonant circuit by moving the driving frequency away from the resonant frequency. The first current from the dimming circuit may be applied to two lamps in parallel, whereas the HF second current passes through the lamps in series (Figs 8, 11). …<IMAGE>…

Title: A method and apparatus for the controlled initiation of nuclear reactions
Inventor: KOLLER KARL
IPC: G21B3/00
Filed: 1990-10-18
Abstract: In a method for producing a nuclear reaction or a nuclear fusion the fusion medium consists of deuterium-containing, non-crystallized polymer, which is conditioned with incident electromagnetic waves for a prolonged period of time, the incident frequency being selected as the tunnel eigenfrequencies of the non-conditioned medium. This leads to operation as a fusion battery, consisting of a metallic container (1) and an electrode (2) of the same metal which is placed centrally and coaxially in the container (1) and with the fusion medium (3) therebetween. A means (5) for receiving current produced is arranged outside the container and connected electrically to the container (1) and the electrode (2). <IMAGE>

Title: Colour reproduction using memory tables for correcting the colour signals
Inventor: O'BRIEN DONAL SEAN
IPC: H04N1/60
Filed: 1990-11-20
Abstract: The system has a memory circuit 14 storing tables with correction values for correction of incoming colour separation signals. A table addressing circuit 15 is used to direct the incoming signals to three relatively small inexpensive memory circuits namely static RAMS 14a, 14b and 14c, for generation of corrected signals. The table addressing circuit, which may be a hard-wired circuit or a dynamically controlled switching circuit, addresses all bits of an associated colour separation signal to a memory circuit together with some of the most significant bits of the other two signals. Thus, memory capacity is optimised with the result that the circuits are relatively simple and inexpensive to maintain and less complex processing circuitry is required. Further, there is no need for feedback circuits for dynamically updating the tables as these are set in response to the type of output device or scanner being used. <IMAGE>

Title: Extendable arm for formation evaluation measurement-while-drilling tool
Inventor: DUCKWORTH ALLEN
IPC: E21B47/01
Filed: 1991-12-13
Abstract: A measurement-while-drilling formation evaluation tool incorporated into a drill collar or sub includes an arm 24 for extending outwardly from the tool and maintaining direct contact between a sensor (22) mounted on the arm, and a borehole wall (18).
