Patent GB-2023762-A (GB)
Title: Reinforced rubber hose
IPC: F16L11/08
Filed: 1979-01-19
Abstract: A reinforced rubber hose has an inner layer 2 of rubber an outer layer 4 of rubber and an interposed reinforcement 5. The end of the hose incorporates an annular reinforcing element 6. This element may be formed from a wire wound into a tight helix with adjacent turns abutting so that the element cannot contract but may expand. This provides a hose end which does not shrink at the ends during ageing following the vulcanisation process and which may be readily connected with coupling devices. The invention is mainly for use in large diameter hose (500 mm or more). The element 6 may alternatively be formed of a number of arcuate parts assemble in abutting relationship to the curvature of the hose and either located around longitudinally extensible guide means or within an electrically expansible tubular member. <IMAGE>

Patent GB-2060419-A (GB)
Title: Improvements in or relating to mixing and conveying apparatus
IPC: B01F7/08
Filed: 1979-10-16
Abstract: Mixing and conveying apparatus e.g. for mixing cement, sand and water, has an outer helix (17) extending at one end, the inlet end, beyond an inner helix (16) so as to closely surround an internal sleeve (4) which rotates with the inner helix at a different speed (in the same or opposite sense) from that of the outer helix. An outer casing (10) affords a mixing trough. The effect of the different rotation between the outer helix and internal sleeve is to squeeze, roll out and flatten cement and water (which is added as a spray (13) over the length of the internal sleeve) to provide thorough mixing and wetting prior to the addition (12) of a foamed mixture of air, water and a foaming agent. <IMAGE>

Title: Improvements relating to slurry spreader nozzles
IPC: B05B1/26
Filed: 1979-11-29
Abstract: A nozzle assembly for a slurry spreader has a selection of nozzles (8, 9, 10) any one of which can be brought into operation to discharge the slurry against an adjustable "spoon" (15) with an upturned downstream edge portion. The nozzles are mounted on a rotatable disc (5) face to face with a fixed disc (3) to the opposite side of which leads a pipe (2) from a slurry pump. The rotatable disc can be turned to bring any selected nozzle opposite the discharge orifice in the fixed disc, and can be clamped in place by a ring assembly (11) which co-operates with the disc peripheries. An over-centre lever device (14) constricts the ring assembly and thereby urges the discs together.

Title: Cutoff valves
IPC: E21B34/00
Filed: 1981-04-13
Abstract: A magnetically operated fail-safe cutoff valve 36, particularly suitable for down hole fluid well applications, is provided having a simple highly reliable valve 48, 49 for equalizing the pressure across the main cutoff valve 36 while closed thereby permitting the same to be opened.

The pressure equalizing valve includes multiple flow passages 51, 52 and is controlled by a shrouded annular armature 47 operable independently of a tubular armature (not shown) controlling the main valve 36. The two armatures may be located in either a common or separate flux circuits. <IMAGE>
