Filed: 1970-08-07
Abstract: 1308470 Removing contaminants from liquids NORTH AMERICAN ROCKWELL CORP 7 Aug 1970 [25 Aug 1969 (2)] 38249/70 Heading B2J The concentration of dispersed contaminant in a substantially non-conductive liquid is decreased by passing the liquid through a channel between opposed electrodes and enhancing the separation of the contaminant from the liquid in the channel through the action of an applied alternating or interrupted electric field by isolating at least one of the electrodes from the liquid using an insulating covering and placing a fuzzy substance 30 which is preferentially wetted by the contaminant rather than the liquid to be purified on only one of the electrodes. The invention is mainly concerned with the removal of water and/or aqueous solution of salts contaminant from hydrocarbon fuels although removal of contaminants from organic cleaning agents, solvents and oils is also referred to. Specific preferentially wetted or hydrophilic substances comprise woolviscose rayon felt, glass cloth or cotton with a rough or fuzzy surface texture. The electrodes may comprise stainless steel foil of substantially E shape and the insulating covering a sheet of polymethylmethacrylate. The insulated electrode may also be wrapped in a bag of vinyl plastic sheeting. The channel is provided with a low level outlet for draining the accumulated contaminant from the channel.

Abstract: 1,080,704. Automatic circuit breakers; thermal switches. TEXAS INSTRUMENTS Inc. Oct. 1, 1964, No. 40054/64. Heading H2B. [Also in Division E2] An overload circuit breaker comprises a manual operator 34 movable between first and second positions to close pairs of contacts 230, 260; 232, 262; a cylindrical latchable member 90 biased by a spring 116 towards the operator 34 to bias it towards its first position and a latch spring 122 arranged to releasably retain both the member 90 and the operator 34 in the second position. The push button 34 and the member 90 are slidable in a cylindrical mounting bush 28 which also carries the latch spring 122. The member 90 is circumferentially grooved at 104 to engage with the latch spring 122. A rod 130 is slidable axially within the push button and member 90 and carries a release cam 176 arranged when moved relative to member 90 to release the latch spring therefrom and permit spring 116 to drive the push button to its open position. A shoulder (136) on rod 130 is engageable through a washer 134 by a shoulder on the push button so that upon depression of button 34 both the rod 130 and member 90 are moved to bring the groove 104 and an aligned notch 180 in the cam 176 into alignment with the latch spring 122 which then holds both members in the second position. A spring 140 between the rod 130 and button 34 retains the button in its depressed position. Mounted loosely about the lower end of rod 130 is a disc 190 biased away from the member 90 by a strong spring 102 but normally latched against the spring by engagement with arm 234, 236 of a bridging contact assembly 200 which incorporates a thermal element 202 through which flows the current. Upon excess current or elevated temperature the bimetal element 202 bows to disengage disc 190 which is therefore driven downwards by spring 102 to strike a flange 150 on rod 130 moving the latter relative to member 90 so that cam 176 disengages latch 122 from groove 104 and spring 116 drives the push button 34 upwards. Meanwhile a spring 240 drives the contact bridge 200 into its open position. Upon subsequent cooling arms 234, 236 re-engage with disc 190 and the contacts can then be reclosed by again depressing push button 34. The push button comprises two differently coloured plastics members riveted together the second of these being visible only in the released condition to indicate the position of the contacts. The thermal element 202 (Figs. 5-7, not shown) may take the form of a zig-zag bimetal clamped between, but insulated from, two U-shaped contact carrying brackets 212, 214 to which its ends are connected.
