Patent GB-2234815-A (GB)
Title: Underwater target searching system
Inventor: HOERING FRIEDRICH
IPC: G01S3/805
Filed: 1981-11-05
Abstract: In an underwater target searching system a large reception angular range and a good angular resolution are achieved by providing on the front surface 1 of the search head 2 a cross-shaped transducer arrangement consisting of a vertical column 3 and a horizontal line 4 which each consists of several individual transducers. The vertical transducer column 3 is used as a transmission transducer for generating a vertically tiltable transmission beam broad in the horizontal direction but strongly focused (thin) in the vertical direction. With the horizontal reception transducer line 4, several overlapping reception direction beams distributed about a broad horizontal range may be generated and therewith the received echo signals can be determined with respect to their angular deviation in relation to the longitudinal axis 8 of the torpedo, each reception beam having a large vertical spread but a narrow horizontal spread. <IMAGE>

Title: Controller for maintaining the width of a continuous web
Inventor: JAMES RODERKICK J
IPC: B29C48/92
Filed: 1981-11-13
Abstract: A controller is disclosed for maintaining the width of a continuous web, for example the diameter of an extruded tubular film or bubble (16). A video camera (26) is used to observe the bubble or tube (16) at a point (20) thereof where it has hardened. The line sync pulses from the camera are counted to provide an enable pulse at the centre of the scanning field at which time clock pulses are counted during a period corresponding to the width of the video pulse, which count is stored in a working counter. The working count is updated once every field, and is compared with a reference count. Any deviations between the reference and working counts produces control signals which drive appropriate air solenoids (32) for modifying the air pressure within the tubular film or bubble (16) until the diameter of the bubble and, therefore, the width of the video pulse, are at their respective desired values. <IMAGE>

Patent GB-2114831-A (GB)
Title: Frequency synthesisers
Inventor: HEEKS JOHN STUART
IPC: H03L7/02
Filed: 1982-02-09
Abstract: A frequency synthesiser is based on a voltage controlled oscillator VCO and a series of for example four phase comparison circuits PC1-PC4. Each phase comparison circuit such as PC1 is supplied with the VCO output both directly and after delay of e.g.  tau  in a delay line DL1. Each phase comparison circuit detects when there is an in-phase relationship between the delayed and undelayed signals. Each delay line has a different delay period and a feedback control signal to the VCO sets it to a frequency at which all phase comparison circuits detect in-phase relationships. The phase comparator outputs are converted to binary form by saturation amplifiers A1-A4 and then combined to give a single digital frequency control signal, which can be then converted DA to analogue form. Injection of a further four-bit frequency selection signal FS, combined with the basic feedback control signal, provides frequency variation. Fine tuning is automatically conducted using the analogue output from the circuit PC1 associated with the least significant bit. <IMAGE>

Patent GB-2095942-A (GB)
Title: Transistor drive circuit
IPC: H03K17/0412
Filed: 1982-03-11
Abstract: A transistor drive circuit comprises a transistor 10 the collector of which is connected through the primary winding 12 of a transformer 14 to a positive terminal 16 and the emitter of which is connected to a negative terminal 18. The terminals 16 and 18 are connected to points of the circuit in which transistor 10 is utilised.The transformer 14 has a secondary winding 20 which is connected across the base emitter junction of transformer 10 and a control winding 24. The control winding 24 is driven by a current source circuit 30 which in turn is driven by a square wave oscillator having Q and Q outputs. In operation, when the Q output of the oscillator goes high, a high current pulse flows through the control winding 24 thereby supplying a turn-off pulse to the transistor 10. At the end of the high current pulse, the current source circuit 30 supplies a low residual current to the control winding 24. When the Q output of the oscillator 64 goes low, the residual current is terminated with the result that the energy stored in the transformer 14 causes a turn-on pulse to be supplied across the base emitter junction of the transistor 10. When the transistor 10 is in its on state, the transformer 14 operates as a feedback path to provide base current to the transistor 10 from its collector circuit. Alternatively, the control winding may be on a separate transformer (303,Fig 5) whose secondary is connected to the base of the transistor. <IMAGE>

Title: Method of treating ore
IPC: C22B1/24
Filed: 1982-04-16
Abstract: Green pellets, of for example hematite and magnetite, are fed into a rotary kiln in which the pellets are fired, by burner 14 and fired pellets are then cooled in a cooler having primary and secondary stages. Air is supplied to the kiln 12 for the purpose of supporting combustion of the fuel burned by the burner 14. Such air is insufficient to oxidise all the oxide in the pellets to a higher oxide. Commercially pure oxygen or oxygen-enriched air is added, so as to provide sufficient oxygen in the atmosphere of the kiln to effect this oxidation.

Abstract: A method of determining the distribution in a sample, of non-proton nuclei having a magnetic moment, comprises subjecting the sample to a magnetic field, irradiating the sample with RF radiation at a proton magnetic resonance frequency, deriving a first NMR signal, indicative of electromagnetic absorption of the sample at the proton magnetic resonance frequency, deriving from the sample a second such NMR signal at the proton resonance frequency in the presence of RF radiation at the nuclear magnetic resonance frequency of the said non-proton nuclei so as to decouple protons in the sample from the said non-proton nuclei, and applying an imaging technique to produce an image indicative of the spatial variation of the difference between the said first and second signals. Imaging may be performed on the difference between the two NMR signals, or on each NMR signal followed by subtraction of the images. The method can be used to trace how a <13>C. labelled material introduced into a patient, and its breakdown products, become distributed.

Title: Pipe linings
Inventor: TRIPPER KATHLEEN
IPC: F16L55/16
Filed: 1983-05-16
Abstract: A spraying device is drawn through an underground pipe and sprays a thixotropic resin onto the inner walls of the pipe. The resin cures and hardens, to form an internal lining to the pipe. The resin has sufficient thixotropy to enable it to be applied in a single operation to a significant thickness, preferably in the range 2 to 25 mm. The lining which is formed upon curing therefore has significant structural strength. To allow such a resin to be pumped from the surface down to the spraying device, along a significant length of tubing, the resin is firstly heated, prior to being pumped. Also disclosed is a swab for swabbing a pipe immediately prior to the application of a lining therein.

Title: Servicing of oil rigs
Inventor: WRIGHT JOHN
IPC: B63C1/12
Filed: 1984-02-09
Abstract: The invention relates to a method and a vessel for servicing oil rigs. The oil rig is raised from the sea onto the deck 30 of a semi-submersible service vessel but not transported from the operating site. Maintenance and repairs are performed at sea with the service vessel providing facilities similar to a floating dry dock. The cost of servicing may in this manner be reduced due to the fact that the rig need only be out of action for a relatively short time. Furthermore the efficiency of the maintenance and repair is improved as compared to such work being carried out under water. <IMAGE>
