Patent GB-2120920-A (GB)
Title: A method and apparatus for determining the mass and moisture content of tobacco
Inventor: SIMMONS A
IPC: A24C5/34
Filed: 1983-03-24
Abstract: The mass and moisture content of tobacco forming the filler stream in a cigarette making machine are determined by a pair of capacitor plates placed on opposite sides of the filler stream forming a test capacitor (11). The test capacitor is connected in a series resonance circuit comprising an inductor (20) and a variable frequency voltage source (21) generating voltages which preferably increase in frequency in finite steps over a range above 1 MHz. The voltage source may be controlled by a processing unit (24) which also receives an indication of the voltage across the test capacitor (11). The mass and moisture content may be derived from the resonance frequency of the capacitor voltage and the magnitude of said voltage at a chosen frequency, preferably the resonance frequency. Signals indicative of mass may be used to control a trimming device (7) preferably in combination with signals from a nucleonic scanner (16).   <IMAGE>

Patent GB-2120055-A (GB)
Title: Data communication system
Inventor: BELL DONALD
IPC: H04L12/18
Filed: 1983-04-26
Abstract: Stations (3) are connected in a series configuration. A station which wishes to transmit waits until it detects a "token", a signal pattern present only when no station is transmitting, converts it into a "connector" and then transmits its own data. The token contains two instances of a first sequence of signals (GO AHEAD) which does not occur elsewhere in the transmissions of the system. To convert the token into a connector each instance of this sequence is changed as it passes in its last bit position into a second sequence (FLAG). This arrangement offers good security against corruption of transmitted data causing a connector to be mistaken for a token while at the same time keeping short the time needed to recognise and change the token. <IMAGE>

Title: Digital to analogue converters
Inventor: MALLINSON ANDREW MARTIN
IPC: H03M1/00
Filed: 1983-06-17
Abstract: For a binary segmented digital to analogue converter embodied in a monolithic semiconductor device, and with a fixed arrangement of sources 12, there being inevitably inaccuracies in the magnitudes of the source outputs, there is provided adjustable means, for example, a programmable read-only memory 30, having an appropriate, empirically derived setting, to determine the order positions of the sources in the sequence in which the sources, possibly additionally, are connected solely to the converter output, via a switching matrix 10, as the values represented by digital input signals to the converter increase from zero, whereby there is obtainable the maximum improvement in the accuracy of the converter in this respect, the consequentially determined increments in the overall stepped converter response, indicated (in Fig. 2, not shown) as A'', B' - - - - G'', H'', being closer to the increments of the ideal response, A, B - - - - G, H than the order positions of the sources in the sequence are arbitrary. <IMAGE>

Title: Remotely sensing of excavation cavity during mining
Inventor: PETRY ESTON F
IPC: E21C45/00
Filed: 1985-09-20
Abstract: Method and apparatus for hydraulically mining a location using a hydraulic monitor which has horizontal and vertical positionable control apparatus. The hydraulic monitor is connected to a source of high pressure water. Distance and direction measuring equipment are mounted on the monitor and controlled in a manner to scan the location. The output from the distance and direction measuring equipment is inputted to a computer and a visual video display monitor. The computer converts the information from the distance and direction measuring equipment to a visual representation of the cavity being mined. The hydraulic monitor includes a means for diverting the high velocity jet during the distance measuring period so that the water pressure is not varied in the high pressure pipe and the mined material is continuously washed toward the collection apparatus during the measuring period. All hydraulic monitor functions are controlled from remote operator location. <IMAGE>
