Title: Flag-type pipeline pig signaller
Inventor: RALLS GENE R
IPC: F16L55/48
Filed: 1984-08-02
Abstract: An apparatus for mounting on a pipeline to signal the passage of a pipeline pig through the pipeline comprises a tubular body member 16, a flag arm 74 hinged to the body member and pivotal between a set and an actuated position. A plunger rod 62 is slideably supported on the body member and engages the flag arm when both are in the set position. A connecting linkage 56 displaces the plunger rod upon the rotation of a shaft (44) within the body member and an engagement member 54 pivotally extends from the lower end of the body member into the pipeline for displacement as a pig moves through the pipeline. The engagement member serves to rotate the shaft through bevel gears when it is displaced to thereby withdraw the plunger rod 62 to permit the flag arm 74 to move to the vertical actuated position under the action of a spring 78. The flat 76 may be reset using a screwdriver in a slot 58. <IMAGE>

Title: Building bricks and blocks
Inventor: RAINBOW LEONARD JOSEPH
IPC: E04B2/10
Filed: 1985-07-26
Abstract: This invention relates to building bricks and blocks and particularly those designed for use in external walls, parapets, or free-standing walls exposed to the elements. Thus a brick has a front or external face 4, a back face 5, vertical perpend faces 3, and top and bottom faces 1 and 2 (Fig 1.). The top face 1 is provided with parallel horizontal channels P which run into forwardly inclined grooves 7 formed on the perpend face and inclined downwards and towards the front face 4. Hence, when laid in the position shown in Figure 1 any moisture penetrating inwards along the top face 1 will tend to be blocked and encouraged to move laterally towards the perpend face. Moisture on the perpend face will tend to move downwards under gravity and the grooves 7 will encourage forward movement of this moisture. Many other embodiments are described and illustrated. <IMAGE>

Title: Hydraulic support for mine roof linings
Inventor: SENDER ZDZISLAW
IPC: E21D/
Filed: 1986-07-01
Abstract: A hydraulic support for a mine roof, permitting a series of small collapses is equipped with two pistons 2 and 4 dividing each prop into two unequal parts. The lower part 5 is of approximately constant volume over a fixed period of use. It is filled with viscoelastic matter absorbing energy of impacts and vibrations. The upper part 6 of variable volume by virtue of a small-"bleed" exit is filled with a well known water/oil emulsion as a hydraulic fluid. Parts 5, 6 are separated by the floating piston 4. Thus, a sudden shock conveys pressure to the viscoelastic material, which deforms to prevent damage elsewhere in the equipment, and then regains its shape with consequent loss of liquid from space 6. <IMAGE>
