Title: Trencher
Inventor: PALMER JOHN EDWARD
IPC: E02F3/20
Filed: 1987-04-15
Abstract: A trencher, adapted to be towed behind and driven from a tractor, comprises a plurality of driven wheels 16 carrying cutting blades 18 and a hopper 28 for containing gravel. There are a plurality of gravel outlets 30 each arranged behind a respective wheel 16. A baffle arrangement 32 is placed between each wheel 16 and its respective gravel outlet 30 so as to prevent a trench dug by the wheel collapsing or filling with soil before being filled with gravel.

Title: Housings for electrical components
Inventor: BEER BRIAN
IPC: H05K3/34
Filed: 1987-05-01
Abstract: An electrical component for mounting on printed circuit boards or other analogous supports is enclosed within a housing of a resilient mouldable plastics material and has one or more connecting pins or tags 4 extending through a wall 1 of the housing via a through-hole provided in that wall. Each of the through-holes is provided with a constricted region, such as the web 3 tapering to an edge 3a, which tightly embraces around the connecting pin or tag 4 passing therethrough. Such an arrangement prevents the ingress of corrosive or inhibiting vapour or fluid into the component arising from the flux used during soldering of the component on to the printed circuit board or analogous support. <IMAGE>

Title: Screening particulate material in a dredging operation
Inventor: MIURA SHIRO
IPC: E02F5/00
Filed: 1988-09-30
Abstract: Particulate material from a dredging operation is screened by apparatus comprising a pivotable upper screen grid, a lower screen grid (42) below the upper grid, and a rotary scraper (45) adapted to move over the upper surface of the lower grid (42). The apparatus receives material dredged from e.g. the seabed, by a backhoe, and larger pieces of unwanted material are retained on the upper grid after earth and sand with smaller pieces of unwanted material have fallen through parallel bars of the upper grid on to the lower grid. The upper grid is pivoted to dump the larger pieces. The lower grid comprises an upper set of parallel rods (43a, 43b) across which the scraper (45) moves, and a lower set of parallel wires (44a) transverse to the upper set. The wires are resiliently supported (44a). A method of dredging is disclosed wherein particulate material scooped up from a sea-bed or sea-shore is transferred to a hopper (3) via the aforesaid screening apparatus, mixed in the hopper to form a slurry and pumped to a place of reclamation via associated onboard, marine and land tubes. <IMAGE>

Title: Optical fibre coil assemblies
Inventor: NASH PHILIP JOHN
IPC: G01L11/02
Filed: 1990-09-22
Abstract: An optical fibre coil assembly for use in systems for the detection of acoustic pressure, temperature etc comprises a coil of optical fibre 1 supported by means of a hollow encapsulating structure 2 and force adjustment means 4 for substantially reducing the overall force which would otherwise act on the coil structure to produce a change of length of the coil when the coil is subjected to acoustic pressure etc. The plates 4,5 seal the ends of the hollow support 2, removing from the central region 3 any influence of external pressure and amplifying axial forces on support from pressures Pe. Outward radial pressure is produced by the axial pressures Pe, the magnitude determined by the size of the central hole and Poisson's ratio of the material. This outward pressure balances the inward acoustic pressure, counteracting any change in the coil diameter and thus its overall length. <IMAGE>

Title: Data security.
Inventor: EUSTACE JOSEPH
IPC: G06F21/62
Filed: 1991-12-31
Abstract: In a processing apparatus (1) having a number of source processors (2) and stored files (4), a security circuit (6) automatically encrypts the header of files of confidential data when an authorised processor ceases to access the file. Subsequently, if an unauthorised processor attempts to access the confidential file it does not recognise it as a data file and access is not obtained. If an authorised processor attempts to access the confidential file a decryption circuit within the security circuit (6) automatically decrypts the header so that access is obtained. A cross reference table (8) is used to determine which processor may access which files. <IMAGE>

Title: Method for separating production fluids
Inventor: KERR HELEN ROSEMARY
IPC: E21B43/34
Filed: 1992-07-29
Abstract: A method for separating a production fluid obtained from an oil well into separate components by means of at least one separator 3 comprises adding water 4 to the production fluid before passage to the separator in an amount sufficient to raise water content of said production fluid to a level where the tendency for the formation of a stable water-in-oil emulsion is reduced. As shown the water which is added is partly obtained from the first separator 3, which is a hydrocyclone, and partly from a supply 7, and may be added to the fluid from well 1 upstream or downstream of pressure control valve 2. Gas is discharged from hydrocyclone 3 at outlet 8 and relatively pure oil 9 is fed to a second stage electrostatic separator 10. A demulsifier may also be added. In an example, increasing the initial water content from 10 to 60% causes a reduction in the final water content of the oil from 8.4 to 1.0%. <IMAGE>

Title: Knitting method
Inventor: ROBINSON FRANK
IPC: D04B1/22
Filed: 1992-09-16
Abstract: Knitted joins are made in double jersey knitted articles using a method which minimises the effect of hole formation at the join. Single jersey edges (14, 18) are knitted along the edges (8, 9) to be joined, being knitted on from one to six needles in each of the courses of knitting which form part of the edge of the join. The edgings (14, 18) need not extend along the whole length of the join. They may be joined directly or through a strip (15). The method is useful for upholstery fabric joins, particularly for vehicle seat covers, where exposure of the padding is to be avoided. <IMAGE>
