Abstract: 1424769 Disc brake wear detectors SUMITOMO ELECTRIC INDUSTRIES Ltd and TOYOTA JIDOSHA KOGYO KK 19 Oct 1973 [21 Oct 1972] 48871/73 Heading F2E A friction pad assembly for a disc brake comprises a back plate supporting a brake lining, a loop of insulated electric wire presenting, at a point in the thickness of the brake lining corresponding to a lower limit of its working thickness, a portion to be worn through by contact with the periphery of a brake disc, and spring means mounted on the back plate and arranged to place a tension on the loop of wire whereby, when the portion is worn through an adjacent end of the wire is removed radially from the periphery of the brake disc. As shown in Figs. 1 and 2, a wire spring 8 has one end located in a hole 17 in a back plate 7, has a U-portion accommodated in a hole 12, has a further U-portion straddling an edge portion 15 of the back plate, and has its other end formed into a loop 11. A loop of insulated electric wire 5 is threaded through hole 12 and a further hole 10 in such a manner that part 13 extends from the lining bearing face through hole 12 to the plain face, while part 9 issuing from hole 10 (which hole extends into a recess 18 in a brake lining 2) lies entirely on the lining bearing face and passes through loop 11 of wire spring 8. A sleeve 14 is then arranged about the two parts 9, 13 and engages loop 11 to apply flexure to the adjacent end of the spring 8. Then, when the right-angled wearable portion 6 of the electric wire loop is worn and broken by frictional contact with brake disc 1, loop 11 of spring 8 springs upwards, removing wire 5 from the vicinity of the disc 1. In Fig. 3, the electric wire 5 is located wholly at the lining-bearing face of back plate 2, and is partly embedded in a moulding 19 of synthetic resin. Hole 17 is omitted, the one end of wire spring 8 being located in hole 12. In Figs. 4, 5, a coil spring 8 located in hole 12 has a loop 11 at each end, and two sleeves 14 are located on wire 5-one adjacent each loop.

Title: Leak detector for pipelines
Inventor: BOSSELAAR HENDRIK
IPC: G01M3/28
Filed: 1967-11-06
Abstract: 1,146,130. Detecting leaks in pipes acoustically. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Nov.6, 1967, No. 50316/67. Heading G1S. Apparatus for detecting and indicating leaks in a pipe-line which apparatus can be transported through the pipe-line comprises equipment for the observation, amplification, selection and recording of ultrasonic signals in such a way that ultrasonic signals arising from a leak can appear on a recorder chart in a recognized form and as a function of either the distance covered or a quantity such as time related thereto and a pressure sensitive element capable of reacting to the pressure in the pipe-line, the signal of which can be used for recording pressure indications as a function of distance or time as the apparatus is transported through the pipe-line, and/or for actuating a switch device by which the said equipment can be partly or entirely switched on or off. It is sufficient for the pressure sensitive element to record whether the pressure is above or below a specific set value, for which a bi-stable element such as a spring- loaded diaphragm may be used. When the pressure drops below the set value, the apparatus is not reliable for detecting leaks and hence the diaphragm operates a micro-switch to switch off the recording device of the apparatus.

Abstract: 1478502 Electrowinning metals FALCONBRIDGE NICKEL MINES Ltd 17 Nov 1975 [25 Nov 1974] 50892/74 Heading C7B In a method for electrowinning metal from a chloride electrolyte in an open cell, the electrolyte fed to the cell is partly withdrawn at an overflow to maintain a constant level, and each anode 11 together with a body of surrounding electrolyte 24 is maintained within an electrolyte-permeable diaphragm 21 attached to a closed hood 22 extending above the electrolyte level 27. Suction is applied to the hood to withdraw gaseous chlorine and a second portion of electrolyte which is drawn through the diaphragm and up into the hood above level 27, whereby diffusion of chlorine through the diaphragm into and evolution of gaseous chlorine from the exposed electrolyte are reduced. A chlorine concentration above the exposed electrolyte of below 1ppm is recommended. Suction may be applied from a common manifold 26 which serves each anode with chlorine and anolyte being removed through a single pipe 25. Alternatively a separate chlorine removal pipe 30 is provided. The anolyte may be dechlorinated and recycled. The cell level 27 may be maintained by an adjustable wier. Usual electrode and diaphragm materials are referred to, for electrowinning Ni or Co. For these metals an anolyte pH respectively below 2À0 and below 1À7 is necessary, and undesired pH rises may be counteracted by feeding fresh electrolyte to and withdrawing the catholyte overflow from the top of the cell.
