Abstract: Abstract                                         C-I-L 667 A process for producing concentrated sulphuric acid from a hot gas stream comprising water and sulphur trioxide which process comprises feeding a first portion of said gas stream through a first sulphur trioxide absorption zone and a second portion through a second sulphur trioxide absorption zone; feeding a recycled sulphuric acid stream to said first sulphur trioxide absorption zone whereby substantially all of the sulphur trioxide and sulphuric acid are removed from said first portion of said gas stream to produce an enlarged sulphuric acid stream; recycling a first portion of said enlarged sulphuric acid stream through said first sulphur trioxide absorption zone; feeding a second portion of said enlarged sulphuric acid stream to said second sulphur trioxide absorption zone; and collecting sulphuric acid product from said second sulphur trioxide absorption zone; wherein the ratio of gases to sulphuric acid in said second sulphur trioxide absorption zone is such that the sulphuric acid product leaving said zone is of the desired concentration to a maximum of the azeotropic concentration.  The process is of value in the production of concentrated sulphuric acid from waste sulphuric acid.

Abstract: HIGH VOLTAGE FILTERING AND PROTECTION CIRCUIT                  ABSTRACT OF THE INVENTION          A high voltage filtering and protection circuit that is particularly useful in multilead distribution systems, that include a live, a neutral and a ground line.  Transient voltage suppressors are connected from a common node to each of the lines.  The suppressors are advantageously silicon diode transient voltage suppressors suitable for high voltage applications, clamping at a rated voltage in one direction and having a forward diode characteristic in the other direc-tion.  Each suppressor may be paired with a parallel filter capacitor protected by its diode from surges or transient voltages.  The paired suppressors and parallel filter capacitor where polarized capacitors are utilized provides an AC equiva-lent capacitor.  In one arrangement, a gas discharge tube is provided in series with the suppressor that is connected from the common node to the ground line.  In another arrangement with or without the gas discharge tube, the suppressors are bidirectional devices with a rated clamping voltage equal to less than the peak line voltage and a predetermined amount greater than one-half of the peak line voltage.

Abstract: Improvements in or relating to electric Motors Abstract A stator assembly of an electric motor includes a lamination stack, a field coil an end cap having a plastics body fixed to the lamination stack, a brush box made of electrically conducting material, mounted on the plastics body and housing brushes resiliently biased towards the axis of the assembly, and a plurality of electrical conductors in the form of strips of predetermined configuration located on the plastics body for making electrical connections between components of the motor.  The electrical conductors include a first conductor extending from the brush box, a second conductor extending from a termination of the field coil and a conducting means, which incorporates an inductance, connects the first and second conductors, The inductance in the connec-tion is altered by altering the inductance of the conducting means.  The first conductor is wrapped around the brush box to give a good and reliable electrical connection.  The end wall of the brush box is connected by a tongue enabling it to be flexed repeatedly to allow brush replacement without the end wall breaking off.  An impedance, typically a capacitor, that is connected across the power supply of the motor is clamped on the end cap by a plastics clamping arm.

Abstract: ABSTRACT A scheme for mounting a permanent magnet group (41) on the flywheel (11) of a small internal combustion engine to provide the moving portion of an ignition system for such an engine is disclosed wherein the engine flywheel is formed of cast iron or similar ferromagnetic material and the magnet group is magnetically isolated from that flywheel so as to minimize short circuiting of the magnet group flux. A generally flat region (21) of the flywheel receives a spacer or plate (35) formed from aluminum or a similar substantially non-magnetic material such as zinc with that plate sandwiched between the flywheel and the magnet group by a pair of aluminum or similar non-magnetic material rivets (27, 29) passing through the flywheel plate and magnet group.  The magnet group is held accurately and rigidly in position by upsetting the rivets in such a manner as to axially compress and therefore radially expand the rivet material so that the rivets tightly fill the respective apertures through which they pass.  A further overlying plate (53) of aluminum, zinc or other non-magnetic material may be included to retain the magnet group in position on the flywheel.

Abstract: ABSTRACT    An interconnecting means comprised of one or more conductive ink conductors printed onto a first substrate, the conductive ink being comprised of an insulating polymer medium having first and second groups of conductive units therein, and an insulating layer of flowable adhesive in covering relationship to the conductors. The first group of units are finely divided particles which are suspended in the medium and form a continuous conductive path along the length of the conductor.          The second group of units are individual or agglomerates of larger particles which are randomly scattered throughout the conductive path and project above the surface of the medium.          Interconnection is effected by locating aligning the first substrate conductors in opposed relationship to conductors on the second substrate such that the flowable adhesive is deposited between the two substrates and applying pressure to the aligned conductors and surrounding areas. The adhesive flows from the aligned areas, exposes the protruding units, thus bringing the units into contact and electrical interconnection with the second substrate conductors accompanied by the adhesion of the remaining first substrate surface to the surface of the second substrate. A method for interconnecting at least one conductive path means of a first insulating member with at least one conductive means on a second insulating member is also disclosed.

Abstract: ELECTRICAL COIL ASSEMBLY AND TERMINAL THEREFOR    ABSTRACT      An electrical coil assembly includes a bobbin having a pair of generally parallel end plates with a pair of terminals inserted into holes in an edge in one of the end plates.  A wall is attached to that one of the end plates and extends radially outward therefrom, being formed with a pair of crossholes each aligned with one of the blind holes. A pair of terminals are partially inserted into the blind holes.  Each of the terminals includes an elongated slot of reduced width at the end remote from the end plate.  A portion of the terminal slot material is lanced out to form a tab at that remote end of the terminal.  The close in ends of the terminal slots are lined up with the crossholes.  Magnet wire is then wound on the bobbin hub and the two ends of the magnet wire are dressed through respective terminal tabs and then resistance welded thereto.  A layer of protec-ive tape is then applied over the surface of the wound coil.  Prestripped lead wires are inserted through the crossholes of the wall and through the lower end of the terminal slots.  Finally, the terminals are driven in the remainder of the blind hole depth.  As a result, the reduced terminal slot widths cut into the lead wires, creating both electrical and mechanical connections.
