Patent CA-2048175-A1 (CA)
Title: Supporting attachment for a sander
Inventor: OCZYNSKI ZDZISLAW
IPC: B24D15/00
Filed: 1991-07-30
Abstract: This patent application refers to an attachment held directly or remotely for supporting and pressing  a tool to machine body surfaces. This arrangement generates an expanding force along a line extending between the point of support on a base and the point of contact on the working tool. The base and the tool have articulated joints thus allowing for freedom of movement in three planes.   The base and the working tool may be connected by either a flexible or a compressed support member. The working tool can be hand held directly or remotely by means of an extendable support and a tool holder. If a power tool is used as a working tool, its operation can be remotely controlled by an on/offswitch.   The tool with the attachment may be especially useful for machining ceiling surfaces, since the tool is automatically supported and elastically pressed to the surface, by the attachment and furthermore may be remotely controlled by operator from a convenient location.

Title: Controller for an electrical load
Inventor: ADAMS DEREK S
IPC: H02M3/00
Filed: 1990-04-06
Abstract: A controller for an electric motor comprises a voltage controlled oscillator circuit (10) the output of which is transformed into a triangular waveform by a waveform generator (12). The output of the generator is applied to one input of a comparator (14). The other input is supplied with an error signal (e) signifying the difference between demanded output and actual output. To lessen the acoustic noise from the controller the period and amplitude of the output of the oscillator, and hence the waveform generator, are varied by a pseudo-random sequence generator (18) which is connected to the oscillator. The output of the comparator is a variable mark/space ratio rectangular wave.

Title: Continuous production of iron-carbon alloy using iron carbide
Inventor: GEIGER GORDON H
IPC: C21B13/14
Filed: 1991-10-09
Abstract: A process for the continuous production of an iron-carbon alloy utilizing an enclosed reactor (10) capable of limiting the ingress and egress of atmospheric gases and gas reaction products respectively. A solid mineral material (20) containing iron carbide and at least trace amounts of iron oxide, and having a weight ratio of at least about 2:1 or greater, is fed into a molten bath (12) of metallic material in the reactor (10). The molten metallic material is simultaneously reacted with oxygen at a temperature sufficient to generate carbon monoxide as a reaction product. The oxygen is preferably injected into the molten metallic material to facilitate the reaction of the oxygen with carbon from the iron carbide to form the carbon monoxide. The carbon monoxide subsequently enters a vapor space (17) of the reactor (10) above the molten bath (12), and further reacts with oxygen to generate carbon dioxide and heat. Products of the described method are also disclosed including a continuous supply of molten iron-carbon alloy. The system or equipment utilized in the present process is also disclosed.

Title: Agglomeration process utilizing emulsion
Inventor: KEOUGH WILLIAM J
IPC: C22B1/244
Filed: 1991-02-28
Abstract: A process is described for the agglomeration of fine particles utilizing a combustible agglomerating agent dispersed in an aqueous emulsion. The process is particularly directed to the handling of fine metal containing particles, originating as by-products or waste products of metallurgical processes, which are to be stored or recycled to metal extractive process steps. The amount of agglomerant added as aqueous emulsion to the particles, is calculated by correlating in an empirical formula the bulk density and the average particle size of the particles, with the emulsified combustible agglomerating agent to be added expressed as weight percent of the particles. The calculated amount of combustible agglomerating agent is emulsified in water, then mixed and blended with the particles, which usually comprise particles of non-uniform size distribution. The aqueous emulsion may also be formed in-situ on the surface of the particles, and the mixture is then blended to form agglomerates. The mixture which is advantageously at a temperature above the ambient, is allowed to cool and be compacted by its own weight. The dust free agglomerates obtained may be stored or charged directly to smelting or refining process steps.
