Patent GB-2048344-A (GB)
Title: Solenoid-controlled safety valve for wells
IPC: E21B34/00
Filed: 1980-05-13
Abstract: A solenoid fail-safe sub-surface safety cut-off valve for fluid wells is controllable from the surface and suitable for installation at substantially greater depths than prior constructions. The valve assembly may be installable and retrievable either via wire line or tubing techniques and utilizes electromagnetic means to operate either a flapper or a ball cut-off valve. The solenoid coil 89 embraces a landing nipple portion of the tubing string or the tubing string itself and holds either type of cut-off valve open against spring pressure only so long as the coil 89 is energized thereby providing surface control of the safety cut-off valve normally and assurance of closing of this valve by energy stored in spring means in the event of power failure through accident or some catastrophe as well as automatic closure if flow velocity increases beyond a predetermined safe value. The valve is provided with spring loaded detent mechanism 85, 86, 87 arranged to exert a restraining force against closing movement of the valve when in the open position, thereby allowing a reduction in the power used to maintain the valve open. <IMAGE>

Title: Improvements in or relating to the treatment of photographic emulsions
IPC: G03C5/29
Filed: 1980-09-23
Abstract: A process for treating a photographic emulsion with at least one treatment medium in liquid form, the process comprising the steps of producing a fine-bubble foam from the liquid, applying the foam to the photographic emulsion in a uniform layer, and allowing the foam to act there. The foam production may be enhanced by the addition of a suitable tenside, and a wetting agent and/or foam stabiliser may also be added. A process in accordance with the invention has been found to allow more consistent treatment of successive films in continuous treatment apparatus.

Filed: 1981-03-26
Abstract: Bone growth is inhibited or promoted by a control component which interacts in situ with bodily material to give an electrical and/or chemical effect and is non-toxically bio-degradable to limit the duration of the inhibition or promotion of bone growth. The control component is discrete from, attached to or integral with a structural component, especially an endoprosthetic component. The component may act as a sacrificial cathode to produce bone growth by an electrolytic action. As shown, an elbow joint member 11 has at its distal end means for promoting thickening of bone 16 therearound comprising a cap element 17 having on its interior surface a layer 19 of bio-active material, particularly brazing or silver solder. The cap may have perforations 25 and may be of surgical stainless steel, titanium alloy (as the member 11) or Co-Cr-Mo alloy. The cap is screwed into canal 15, the member 11 is a force fit into the cap and is cemented 21 in a reamed-out portion 14 of the canal. The bio-active material may alternatively be such as to cause laying down of calcium apatite by chemical activity, or to inhibit bone growth by establishing an area of positive potential; no examples of such materials are disclosed. <IMAGE>

Title: Load bearing harness
Inventor: LANGFORD KENNETH EDWARD
IPC: B63B35/79
Filed: 1982-01-18
Abstract: Harnesses worn during windsurfing to take most of the force from the sail can exert dangerously large compression forces on the wearer's rib cage. Accordingly the harness 10 is provided with a relatively rigid and stiff bar 18 across the front and/or rear so that forces on a hook 22 attached to the harness for temporary attachment to the sail or mast are transmitted to the sides 16 of the harness via 17 so reducing the tendency of the harness to contract width-wise. The invention also extends to the bar itself since it may be incorporated into an existing harness. <IMAGE>

Title: Data logging and label printing device
Inventor: STAMMERS HUGH
IPC: B41J3/44
Filed: 1982-08-26
Abstract: A combined data logging and label printing device comprises a computer processing unit 3, programmed to drive the various functions of the device, a keyboard 4 for use by the user to input data and interact with the processing unit, a displays for displaying the text input by the user and which is to be printed using one of two printers 6a and 6b on label stock and a micro cassette recorder 7 acting as a non-volatile memory for storing data relating to each prepared label. The printers may carry labels which are marked by colour or other marking to distinguish between, say, poisonous and other products. The processing unit 3 is programmed so that unless the user gives instructions to the contrary, a label will normally be printed on one of the printers unless he or she specifically instructs the other printer to be used. The printer normally used can be selected by the user during the start up routine of the device so as to even out wear on the two printers. <IMAGE>

Title: Plant growing block comprising a number of separable plant growth bodies
Inventor: LOVGREN BENT
IPC: A01G31/00
Filed: 1982-10-01
Abstract: A plant growing block 1 consists of bound mineral wool and comprises a number of coherent plant growth bodies (2) mutually separated by means of two mutually perpendicular sets of parallel grooves (4, 5), the depth of which corresponds to the major part of the height of the growing plant means. The fibres of the block are arranged substantially to lie in planes perpendicular to the surface of the block, eg plane 3. The roots of plants will spread more readily within planes parallel to plane 3 than perpendicular to such planes and as a result the grooves 5 need not be as wide as the grooves 4 and the rigidity of the block is increased. <IMAGE>

Title: Automatic testing equipment
Inventor: MORRISON JOHN MALCOLM
IPC: G01R31/308

Abstract: In automatic testing equipment, for the inspection of unpackaged electrical devices, each such device comprising a planar substrate 10, with a conductor pattern 12, 13, 14, and possibly electrical components, thereon, radiation, either reflected or transmitted by the device, is received by detection means sequentially from predetermined regions extending along a pattern of scanning lines 20 on a major device surface 11. A sequence of operands is produced by an operand providing circuit arrangement, each operand being representative either of a function of a plurality of detected radiation intensities; and/or of forms of, and/or of spacings between, on the major device surface, abrupt transitions of the radiation intensities detected at element boundaries; and/or of element corner regions. The operands are compared with corresponding operands produced within the equipment, the arranged being such that a significant difference between compared operands is indicative of a construction fault in the device. <IMAGE>

Title: Direction-finding aerial and receiving system
Inventor: MCLAY JAMES ALEXANDER
IPC: G01S3/38
Filed: 1983-05-04
Abstract: A direction-finding radio aerial consists of a horizontal ferrite aerial rod 10 having on one arm a helical aerial 14 and on the other a coil 16; the rod is mounted on a rotatable vertical shaft 12. The field from a radio transmitter is concentrated in the rod 10 and the e.m.f. generated in the aerial 14 is dependent on the angle of the rod to the incident field, in accordance with a 'figure of eight' diagram. Coil 16 has a large number of turns and provides an e.m.f. due to its rotation in the earth's magnetic field. The phase of the envelope of the r.f. signal relative to the e.m.f. generated due to the earth's magnetic field gives the bearing of the transmitter from the receiver relative to magnetic north. Figure 3 (not shown) illustrates a circuit diagram with an a.m. receiver, a null detector, a d.c. amplifier and a phase shifter. <IMAGE>
