Abstract: 1406757 Endless conveyer belts GOODYEAR TIRE & RUBBER CO 9 May 1973 [8 June 1972] 22031/73 Heading B8A [Also in Divisions B7 and H3] Apparatus for indicating whether or not a conveyer belt is torn, comprises an inductive loop 16 (without a switch 18) to be embedded in a conveyer belt, a detector circuit 10, and an indicator circuit 14. When the conveyer belt is not torn, the loop is closed and the inductors L1, L2 are magnetically coupled each time the loop 16 is proximate the circuit 10. Such coupling results in an output from the circuit 10 and energizing of the lamp 62. When the loop is open (due to a tear), no such coupling occurs and this results in energizing of lamp 68. The conveyer belt may include a plurality of loops, and a single circuit 10 or a plurality of circuits 10 may be used. When a plurality of circuits 10 are used they may be coupled to a common indicator circuit or each may be coupled to a respective indicator circuit. The or each indicator circuit may be coupled to an ON/OFF controller so that the conveyer belt may be automatically stopped when a tear occurs.

Abstract: 887,699. Fluid-pressure servomotor control systems. NATIONAL RESEARCH DEVELOPMENT CORPORATION. July 7, 1959 [July 11, 1958], No. 22273/58. Class 135. A body 11, Fig. 1, has an inlet 14 leading to a pair of chambers 18 through a space 15, the chambers 18 being each provided with a leakage outlet 19 terminating in apertures 21, 22, Fig. 3, at a smooth-flat body-face 23, Fig. 1. Each chamber 18 is connected by a passage 25 to the opposite ends of a valve 13. A shaft 12 rotatable about an axis normal to the face 23 has two flat faces in close proximity to the face 23 which register with the apertures 22, 23, as shown. Upon rotating the shaft any given amount from the neutral position shown one aperture is wholly or partially opened and the other correspondingly closed whereby the pressure in one chamber rises and that in the other chamber falls and the valve 13 is accordingly moved. The obturating end of shaft 12 is cut away to provide reaction faces so that as the shaft is displaced from the neutral position the fluid flow over it either tends to increase or reduce this displacement or to have a zero effect, depending on the shaping of the reaction faces. The obturating end of shaft 12 is recessed between the flat faces, but the latter may be provided on the ends of projections. The shaft may be turned by hand or an electromagnetic device in an automatic fluidcontrol system. The apparatus may be used in a system controlling an aircraft control surface, not shown. The shaft, which may be positioned in a container forming part of a closed circuit, may be immersed in the operating fluid; the leakage fluid may drain to a reservoir in which case the shaft is not immersed but is exposed to the atmosphere.

Title: Method and Apparatus for Purification of Waste Materials
Inventor: KELLUM JAMES JACKSON
IPC: C02F3/12
Filed: 1967-05-16
Abstract: 1,196,324. Discharge apparatus. J. J. KELLUM. 16 May, 1967, No. 22576/67. Heading H5H. [Also in Division C1] Waste material containing micro-organisms e.g. sewage are treated by passing atmospheric air through an electrical discharge grid pack where the air is subjected to electrical discharge and forms activated gases, passing the activated gases into an outlet chamber where any ozone present degenerates, and discharging the ozone free activated gases into the system containing the waste materials. The activated gases are oxides of nitrogen which are introduced to the liquid sewage by absorption and dissolution of gaseous acid anhydrides and mists to provide the necessary environment for the microbes responsible for the digestion of sewage. The activated gases are preferably introduced some miles before the usual sewage treatment plant with the result that the total and suspended solids reaching the plant are reduced; rusting of metal, corrosion of paint and concrete in sewer lines and buildings are eliminated; slime on pipes is prevented; sulphides are oxidized to odourless compounds; and grease in the sewage reaching the treatment plant is reduced. In operation, the grid path 26 is first dried by heated air from an auxiliary heated blower 14, 16; the blower 14, 16 is switched off and simultaneously a transformer 38 supplying the grid pack 26 is energized; and finally the main blower 2 is energized so that air is drawn through filter 8 to chamber 6, through chamber 10 to grid pack 26, from grid pack 26 to de-ozonizing chamber 28 and finally from chamber 28 to the sewer system. The grid pack comprises vertical electrodes of aluminium wool, coarsely woven aluminium, or laminates of expanded aluminium separated by vertical glass insulating plates and spaced therefrom by glass spacer elements.
