Abstract: A sprocket (16) and a module (8A-8F) for forming a heavy duty, smooth top, straight running conveyor belt which is easy to clean and which uses a center transverse tooth member (34A, 34B) to receive a driving force from an intermeshed sprocked (16) is disclosed. Each of the modules (8A-8F) is suitable for being pivotally connected with a multiplicity of similar modules by pivot rods (10A-10E) to construct a conveyor belt. Each of the modules (8A-8F) includes first and second pluralities of link ends (14A-14C) which are aligned in the module (8A) to form first and second pivot axes. Each of the link (14A-14C) ends have a topmost portion (26A, 26B) which has a width which is just less than the space between two adjacent link ends on the same module (22A), such that when intermeshed with link ends of another module (22B) a continuous, flush, smooth top surface is provided. The pluralities of link ends of each of the modules are joined by an integrally molded smooth top connect­ing structure which includes a tooth member (34A, 34B) extending downward and parallel to the pivot axis.

Abstract: A metal oxide ceramic composite powder comprises crystals of a reacted and precipitated non-ferrous metal oxide distributed on fine particles of a ceramic material. The metal oxide is derived from an aqueous solution of a non-ferrous metal chloride which, in the presence of a magnetic field, forms a complex ion solution. The complex ion may comprise a proportional blend of non-ferrous metallic and semi-metallic elements to produce specific properties. The complex ion is reacted and precipitated with an alkaline material to deposit a high purity non-ferrous metal oxide on the ceramic material. Each ceramic particle, thus, has a uniform coating of a high purity non-ferrous metal oxide deposited thereon.

Title: Power supply system.
Inventor: ECKERSLEY GREGORY PETER
IPC: H02J1/14
Filed: 1990-02-06
Abstract: A power supply system (10) comprises a multi-phase AC supply (12) which is provided to an AC-DC converter (14). The DC output from the converter (14) sources power to a DC bus (16), which then provides power to a secondary supply bus (42) and electrical loads (38, 40). The convertor (14) connected to the DC bus (16) by a master controller (22), which is controllable by master control processor (30) to disconnect the two. In a similar way, the secondary supply bus (44), load (38) and load (40) are connected to the DC bus (16) by slave controllers (46), which are each controllable to effect disconnection through action of the respective slave control processors (48). When any of the secondary supply bus (44) or loads (38, 40) demand power from convertor (14), a demand request is passed by the respective slave control processor (48) to the master control processor (30) via data bus (32). The master control processor (30) then determines whether the demand request is legal based on a maximum permissible power request and will also consider the instant cummulative sum of power required to be provided. If the request is legal, a demand authorisation is returned to the slave control processor (48), and the power can be drawn. If the request is not legal, the master control processor (30) can require one or all slave control processors (48) to power down the electrical load through operation of contractors (24) in the respective slave controllers (46). Alternatively, the slave control processor (48) making the demand request can be caused to effect the regeneration of power. In the instance of serious faults, the master control processor (30) can cause the DC bus (16) to be powered down by effecting operation of contactors(24) within the master controller (22). <IMAGE>
