Title: Fan casing and fan blade loading/unloading
Inventor: MULLINS JOHN ALBERT
IPC: F01D25/24
Filed: 1988-02-23
Abstract: A fan casing 26 of a turbofan gas turbine engine (10, Fig. 1) has an aperture 38 which extends completely through the fan casing. A variable pitch fan blade 40 may be removed from the turbofan by rotating the fan rotor 48 so as to align the tip of the fan blade with the aperture 38. The fan blade is detached from the fan rotor and is moved radially through the aperture 38 to remove the fan blade. The aperture 38 in the casing allows the fan blade to be loaded by the reverse procedure. Thus loading/unloading of one or more fan blades is made possible without removing the fan casing. A plug 52 is removably secured in the aperture 38 to form a continuation of the interior and exterior surfaces of the fan casing.   <IMAGE>

IPC: F16L55/165
Filed: 1988-05-09
Abstract: Includes taking a length of liner pipe 7 made from a memory retaining plastics material of external diameter greater than the internal diameter of the pipework 10 to be lined, subjecting the liner pipe 7 to a vacuum (eg. through nozzle 14), drawing the liner pipe 7 through a swaging die 3 using pulling means 11 under tension attached to the leading end of the liner pipe 7 and threaded through the pipework 10 to reduce the external diameter of the liner pipe 7 by up to 15%, the tension applied by the pulling means 11 being such as partially to restrain the radial expansion of the outer surface of the liner pipe 7 after its emergence from the die 3, drawing the liner pipe 7 through the installed pipework 10 with its outer diameter reduced to and/or maintained at a dimension less than that of the inner diameter of the pipework 10 and thereafter allowing the liner pipe 7 to expand within the pipework 10 by relaxation of the said tension followed by memory induced expansion at ordinary atmospheric pressure and at the ambient temperature of the pipework 10. <IMAGE>

Title: Soil stabilisation
Inventor: HAQ IKRAM
IPC: E02D17/20
Filed: 1988-11-11
Abstract: In a method of stabilising a slope or a side wall 21 of an excavation 20, which method does not require the use of heavy hammer action equipment and does not incorporate a grouting operation, a plurality of mutually spaced rigid ground anchors 22 are screwed into the ground at angles to the face of the slope or the side wall of the excavation. Each ground anchor 22 comprises a rod 1 having over at least a part of its length nearer its leading end 4 at least one helically extending fin 11 which cuts its way through the soil as the rod is rotated about its axis. The method is especially applicable to the soil nailing technique but it can also be employed in the reticulated micro-piling and dowling techniques. It is suitable for both permanent and temporary stabilisation of slopes and side walls of excavations and where temporary stabilisation is required each ground anchor 22 can be readily unscrewed from the ground and reused elsewhere. <IMAGE>

Title: Small-diameter metal bar or conduit bending machine
Inventor: KIMURA SADAO
IPC: B21D11/10
Filed: 1989-07-07
Abstract: The machine comprises a stationary frame segment 1a and a movable or separated frame segment 1b, each including a bending station (51, 52). Where a metallic conduit seems to interfere with the movable frame segment 1b kept in its normal position when the metallic conduit is bent by a bending member, the movable frame segment is displaced e.g. by pivoting by a cylinder 11 to avoid interference, a subsequent bending work is performed beforehand, and then the subject bending work is performed after the movable frame segment is returned to its normal position.

Title: Electronically self-latching cylinder lock
Inventor: TZOU KAE MIN
IPC: E05B49/00
Filed: 1990-04-19
Abstract: An electronically self-latching cylinder lock comprising a cylinder 10 into which a plug 18 is inserted, a plurality of paired pin tumblers each of which is disposed in one of a plurality of bores formed inside the cylinder and the plug, and a plurality of switches 11 which are controlled by the pin tumblers. The switches are used to actuate an electronic circuit to send out warnings with a buzzer and to secure the plug at its locked position with a latch 32 which is driven with a solenoid, when an incorrect key is inserted into the key way. Once the key is inserted and the switches 11 closed, rotation of the plug 1B causes movement of a control pin 171 by means of a cam surface, to close a switch 113. Provided this happens within a predetermined time from actuation of any of switches 11, locking of the plug by latch 32 does not occur. <IMAGE>

Title: Method of quantitative analysis of drilling fluid products
Inventor: JONES TIMOTHY
IPC: G01N15/06
Filed: 1990-05-23
Abstract: A method of quantitative analysis of products, such as barite, bentonite or polymers, in a drilling fluid circulating in a wellbore being drilled is described. The method comprises the steps of sampling the drilling fluid, and analysing the sample to determine the density of the fluid and the weight fraction of solids in the fluid. In addition, a known weight of the sample is dried to constant weight so as to obtain the products in the form of solids, which solids are analysed by an infrared spectroscopy technique. The concentration of the products in the drilling fluid is then determined. The method can be applied to the control of the drilling operation by monitoring the quantity of products added to the drilling fluid, such as barite and polymers, or a product coming from the borehole wall or the underground formation being drilled. The invention also applies to the control of the working condition of the mud solids equipment. <IMAGE>

Title: Image data transmission using sub-band coding and intermediate recording
Inventor: STONE JONATHAN JAMES
IPC: H04N7/26
Filed: 1991-09-04
Abstract: An image data recording and transmission system is described in which a data compressor 76 decorrelates input image data into sub band component data, a data recorder 78 stores the sub band data, a data decompressor 80 decompresses data read from the data recorder and a transmission signal generator 82 produces a bandwidth limited transmission signal from the decompressed data. The combined action of a data sequencer (18 Fig. 1), a quantiser (14) and an entropy encoder (20) within the data compressor act to remove from the data stream that information corresponding to frequencies not transmittable with the bandwidth limited transmission signal (e.g. PAL or NTSC) subsequently produced by a transmission signal generator 82. Accordingly. the data recorder need not use storage capacity recording data which cannot be used by the transmission signal generator. <IMAGE>

Title: Display device for videocassette recorder recording reservations
Inventor: HASHIMOTO KAZUO
IPC: H04N5/765
Filed: 1993-07-26
Abstract: A device which allows a user to enter TV program recording reservations into a VCR memory and record the TV programs on videotape based on the reservations. This device is also capable of distinguishing between reservation data for TV programs which have been recorded and those which have not. TV program reservation data may be entered via keyboard 10 or remotely using telephone set 1. At the time of recording of a reserved TV program, a mark indicating that the recording has been performed is stored in RAM along with the data for that reservation and this mark is stored for a prescribed period of time. When review button 10-2 is pressed, TV program reservation data is displayed on LCD 14. The display changes depending on whether or not the above-mentioned mark is stored in RAM and it is thus possible for a user to determine whether the reserved TV program has been recorded. Various other arrangements am described, including ones where the programme reservation data is recorded on the tape. An indication may also be given of the number of programmes recorded. <IMAGE>
