Patent GB-2140404-A (GB)
Title: Stable an/emulsion explosives and emulsion for use therein
Inventor: CESCON LAWRENCE ANTHONY
IPC: C06B47/14
Filed: 1984-05-11
Abstract: Sensitised explosive blends of a water-in-oil emulsion and AN particles, e.g. AN or ANFO prills, have improved stability when their structure hinders the loss of water from the aqueous emulsion phase and transfer of such water across the oil phase to the AN particles. Such structure may be obtained by using an anionic emulsifying agent comprising a fatty acid salt, e.g. as formed in situ, to form the emulsion. Blends stabilised in this manner form storage-stable packaged products and can be pumped to boreholes through an annular stream of aqueous liquid flowing co-currently in the conduit. An emulsion is disclosed having a dispersed aqueous phase of oxidising salt solution and a continuous liquid carbonaceous fuel phase which contains a fatty acid and a fatty acid salt as an emulsifying system, the weight ratio of oil to fatty acid being in the range 1:1 to 3:1.
Patent GB-2143036-A (GB)
Title: Ultrasonic resonance for detecting changes in elastic properties
Inventor: CHARLESWORTH DR JOHN PHILLIP
IPC: G01N29/12
Filed: 1984-06-26
Abstract: Some forms of corrosion, and inter-granular attack in particular, occur without significantly altering the bulk dimensions of the body attacked 22. Where the elastic properties of the body are changed by corrosion, this is detected by ultrasonic inspection based upon determining the resonant frequency or frequencies with which pulsed ultrasonic signals, 2-5, reverberate within the body. Resolution is improved by gating out the first, top, surface reflection, 1, and by swept gain control through the gating period. The resonant frequency or frequencies are then compared with those of a sound body. Any shift in frequency indicates corrosion. The method is particularly suited to inspection of heat-exchanger tubes by means including an ultrasonic mirror (Figures 4, 16) but may also be used for plates (Figure 3). The ultrasonic signals may be transmitted and received by a single transducer, 21, or separate transmitting and receiving transducers may be employed (Figure 15). The received signals may be viewed on a CRT after spectrum analysis (Figures 6-13) or by grey-scale image construction after digitising (Figures 14, 17). An alarm may be operated if a frequency-change threshold is exceeded. <IMAGE>

Title: Encoding method for time encoded data
Inventor: KING REGINALD ALFRED
IPC: H03M7/42
Filed: 1985-06-27
Abstract: A method of encoding time encoded data such as speech in which a stream of time encoded symbols representing the data is divided into a number of successive time frames. The repetition frequency of each symbol in each time frame is determined and a precursor code, indicative of the symbols according to their repetition frequency, is derived for each time frame. A linear or non linear code, or any combination thereof, is assigned to the symbols in accordance with the precursor codes to produce a code series for each time frame. The precursor codes and code series for the time frames are then combined thereby to achieve a reduction in the bit rate of the digital data stream representing the data. The combined precursor codes and code series may be stored before or after transmission. <IMAGE>

Title: Anode x-ray source
Inventor: BIRD CHARLES RICHARD
IPC: H01J35/10
Filed: 1986-04-01
Abstract: An x-ray source having a cathode and a disc-shaped anode with a peripheral surface at constant radius from the anode axis opposed to the cathode. The anode has stub axle sections rotatably carried in heat conducting bearing plates which are mounted by thermoelectric coolers to bellows which normally bias the bearing plates to a retracted position spaced from opposing anode side faces. The bellows cooperate with the x-ray source mounting structure for forming closed passages for heat transport fluid. Flow of such fluid under pressure expands the bellows and brings the bearing plates into heat conducting contact with the anode side faces. A worm gear is mounted on a shaft and engages serrations in the anode periphery for rotating the anode when flow of coolant is terminated between x-ray emission events.
