Filed: 1975-01-06
Abstract: 1444081 Rotationally moulding pipes ROCLA CONCRETE PIPES Ltd 6 Jan 1975 [4 Jan 1974] 481/75 Heading B5A A roller 13 (Fig. 1) supports and rotates on rings 18 a mould 12 while concrete is added to form a pipe 11, until the concrete layer is thick enough to disengage the roller and rings. After the rotating roller 13 has compacted the concrete layer, one or more air jets 37 remove concrete from the inner periphery of the pipe 11 until the roller and rings re-engage. The roller 13 is supported by a hinged gate 17, and locating collars 19 bear against the rings 18 which define a spigot and a socket. Concrete from a shoot 36 is fed by an endless belt 20 (Fig. 2) into the mould, by moving an arm 24 running on rollers 28 and 32. The belt 20 is reciprocated by a handle 34 (driving roller 32) to fill low spots. The arm 24 also supports at least one air jet 37 comprising an air jet tube 38 (Fig. 2) fed by a flexible hose 56 and mounted on lever arms 46, 42, 43 pivoted at 41. A push-button or lever operates a pneumatic cylinder 45 that pivots the lever arms 46, 42, 43 between stops 51, 52 for engaging a guide shoe 47 against the pipe 11, and directing the air jet at an acute angle to the pipe wall behind the roller 13. The or each air jet removes concrete along a spiral path, the groove or grooves formed being filled in by the roller 13. In an alternative embodiment, the air jet is rigidly attached to the arm 24, which also supports a jet for cleaning the roller 13 (see Figs. 4, 5, not reproduced).

Filed: 1986-01-07
Abstract: PURPOSE:To measure with high accuracy and with high sensitivity a current wide in range extending to an accident current area without being influenced by an external magnetic field, by providing a photomagnetic sensor which is constituted so that a light beam is brought to a repeated reflection between a gap plural times, between gap opposed surfaces of an annular iron core with a gap, which is placed in the periphery of a conductor in which a current to be measured flows. CONSTITUTION:A light beam which has reached a photomagnetic field sensor 17 through an optical fiber 7 from a light emitting part 6 goes to a linearly polarized light small in expansion by a lens 17a and a polarizer 17b, and made incident on a Faraday effect element 17c. Such linearly polarized light is reflected in a state that the plane of polarization remains maintained by a polarization plane maintaining multi-layer films 17f, 17g, as shown by an optical path 18 and transmits through in the element 17c. On the other hand, in accordance with a value of a current flowing in a conductor 2, a magnetic field H in a gap of an iron core 14 is varied. Therefore, a transmission light of the element 17c whose polarization plane has rotated in proportion to a current flowing to the conductor 2 is reflected plural times by a boundary surface to the multi-layer films 17f, 17g, a light beam having magnitude depending on a rotation of the plane of polarization goes into an optical fiber 8 through an analyzer 17e and a condensing lens 17f, and a photodetecting part 12 converts photoelectrically this light beam and outputs it.
