September Technical Group Meeting.
The meeting started at 8.04pm with eventually about 24 people present. (give or take a few) Robert began proceedings by talking about the inventor competition which is to be held again at the December monthly meeting. It has been decided by the committee that anything that has been presented during the year can be entered. A short discussion followed with Ken making the point that people involved in large ongoing projects cannot really present it on one night.
The meeting moved on with Ron telling us how he made a weedkiller dispenser for Roger to get rid of multiple weeds at one time. It consisted of a couple of wheels, a handle to pull it along and a pipe with a towel wrapped around it to dispense the Roundup. Apparently it has been very successful. Ron also brought along a can of Lanotec (available from CBC Bearings) which is like CRC made from lanolin from sheep's wool. He showed a steel rod which had untreated and treated sections to demonstrate how the Lanotec prevented rust from forming.
Another ingenious device brought along by Ron was an old spray can into the bottom of which he had soldered a bike tyre valve assembly. The liquid that you want to spray is then fed into the can through the valve assembly (valve removed!) with a syringe. Refit the valve and pump the pressure up with a bike pump and you have your own recycled spray can. Ron also demonstrated how you can use an old battery drill that has a dead battery by running it from a computer power supply. It can be run directly from the 5Volt rail or the 12Volt rail but if using the latter, the 5Volt rail must be loaded with a lamp or the supply will be stuffed. The red and black leads have the 5Volts on them and the yellow and black leads have the 12Volts.
Finally Ron showed his version of the Beck Zapper using surface mount components and batteries fitted directly to the board. He also demonstrated a Beck Pulser using an old flash unit and a coil wound from 130 turns of 1.7mm wire. The demo concluded with some jumping steel washers being repelled off the coil. Robert added a comment that he always uses the north pole next to the body when using a pulser. He also mentioned a link from our website to another website on a Colloidal silver generator that uses 6Volt DC and a fish tank aerator to produce better quality colloid. Frank continued the discussion by saying that he had experienced different effects with silver production depending on the moon cycles. The final comment on this subject was from Peter with information that the Russians had used massive currents and a large silver bar to produce a white powder which when remixed with water formed colloidal silver solution. Uli also mentioned that 27.3 Volts seems to be a magic number with respect to making the colloid. He referenced a book called "Gods Secret Formula" by Peter Flichta for this information.
Uli presented a cheap and effective fuel preheater for DIESEL
VEHICLES ONLY!! that he has designed and built using off the
shelf components. Uli came up with the design to overcome cold
starting problems while running recycled veggie oil in diesels.
The preheater heats the fuel to around 80 degrees Celsius with
the fuel being heated from near the fuel pump right up to the
motor. The unit consists of a 10mm pipe run from the low pressure
pump up to near the motor. Over this pipe is placed some 16mm
rubber hose with a 16mm T piece at each end. This enables the
outer hose to be sealed at each end as shown in the diagram with
the hot water from the engine cooling system being fed in one
T piece and out the other. Uli then gave a brief outline on how
the oil is treated to make it suitable for using in a diesel
Jim believes that the "black box" is actually a homopolar generator and has done some experiments of his own with one of these devices. Jim's unit consisted of a 6 inch by 1/4 inch copper disc fitted with a 3 inch speaker magnet on each side. The output was taken off by two brushes , one on the centre axle and the other on the outer rim of the disc. Jim found that this unit produced a low voltage of 200mv with a current of 6 amps. A discussion on various forms of this generator followed with Jim organising a workshop the next day to build one.
Finally there were some short discussions on different subjects
with the meeting concluding at 10.16pm.
William from Byron Bay contacted me regarding Joecell
research, could any perspn working on similar technologies please
contact me so that I may put him/her in touch with William.
From the text book.
Current flow that results from an induced e.m.f. will produce a field about a conductor in which the e.m.f. is
induced. The direction of action of such an induced field is defined in Lenz's law: The direction of an induced e.m.f. is such that the resulting current flow will produce a magnetic field which tends to oppose the original motion causing the induced e.m.f.
This is the electrical counterpart of Newton's third law, which states that: Action and reaction are equal and opposite. The application of Lenz's law is illustrated (see diag) in the downward movement of a conductor through a magnetic field as a result of mechanical force acting in this direction. This downward movement through the field will induce an e.m.f. in the conductor and the resulting current will create a circular magnetic field around the conductor. For Lenz's law to apply, the induced field must oppose the motion. To do this, the direction of the induced field must be such that the following reaction will occur between the main and induced fields:
1. The main field will be strengthened below the conductor and weakened above it.
2. The resulting magnetic force should then act upwards in opposition to the motion of the conductor.
