Abstract: ABSTRACT OF THE DISCLOSURE         A soil supplement for addition to potted plants con-sisting of micro-organisms, enzymes, and various substances rich in protein and carbohydrates including bone meal, torula yeast, potassium citrate, soybean flour and durum wheat flour.          The potassium citrate acts as a chelating or sequestering agent.          The substance is added to water used to water the potted plant.  The effect of adding this to the water is that the micro-organism count greatly increases due to the micro-organisms and enzymes acting on the various substances rich in protein and carbohydrates.  The sequestering agent tends to maintain the  solution   in suspension through the earth.          Any salts accumulated on the surface of the soil or on the edge of the pot are gradually sequestered into the soil and are ionized by the action of the enzymes and micro-organisms to produce minerals useful for the plant. The micro-organisms break down any dead root structure, giving the live roots more room.  After continued use, the soil around the plant becomes light and porous.       A preferable composition is from one to two percent of micro-organisms, two to ten percent of enzymes, five to twenty percent of bone meal, fifteen to thirty percent of torula yeast, eight to fifteen percent of potassium citrate, five to fifteen percent soybean flour, and thirty to sixty percent of durum wheat.

Abstract: A B S T R A C T.           A purification process for removal of suspended solids, carbonaceous material, nitrogenous material, phosphorus, refrac-tory organics, bacteria and viruses comprises of combining and carrying our the various biochemical and chemical reactions and separation of the suspended solids in a single sludge system in a simplified process sequence suitable for use in a single reac-tion tank.           The biooxidation, nitrification, denitrification and chemical predipitation processes are carried out in presence of mixed mi-crobial population entrapped into fluidized nonbiodegadable sus-pended solids with portion of the fluidized suspended solids cir-culating through three reaction zones having varying concentration of disolved oxygen to maintain enviromental conditions to support growth of the microbial population and simultaneously to maintain operating conditions required to carry out the involved reactions.           The fluidized suspended solids entrap the active microorganisms, colloidal matter and suspended solids present in the incoming waste water and/or generated during purification of the waste water, imp-rove the settling properties of the resulting sludge and enhance separation of suspended solids from the purified waste water.           The concentration of the active microbial population in this purification process is significantly higher than that achieved by the prior art processes resulting in better performance, more effi-cient removal of pollutants and reduced treatment costs.  The follo-wed chemical oxidation provides for removal of remaining impurities and killing of bacteria and viruses.

Abstract: IMPLANTABLE RECEIVER CIRCUIT             Abstract of the Disclosure In an implantable receiver circuit there is provided a tuned filter responsive to externally pro-vided radio frequency energy bursts.  The receiver also includes a pair of oppositely poled diodes for res-pectively providing positive and negative rectified versions of the energy bursts.  The cathode of one diode is coupled through a low-pass filter circuit to an output capacitor and the anode of the other diode is coupled through a low-pass filter to the control elec-trode of a semiconductor switching device, the main electrodes of which are coupled between the output capacitor and the point of reference potential.  With this connection the switching device is rendered con-ductive during the time no energy burst signals are applied to the tuned circuit thereby allowing the out-put capacitor to discharge during this time.  During the time an energy burst is provided, the second rectifier circuit maintains the switching device non-conductive.

Abstract: A METHOD OF DECODING WAVEFORMS                         ABSTRACT    A method for reading or decoding the self clocking encoded data content of digital data bits encoded in the standard F2F or in phase shift format is described.  The method is useful for decoding F2F or phase shift code signals presented in the form of optic, magnetic, or electric signal variations presented to a decoding apparatus for the extraction of data therefrom.  The technique utilizes the measurement of the interval of time or distance elapsing between two like polarity signal transitions to determine the data content of that segment of the waveform bounded by the two similar polarity transitions.  The data con-tent of that portion of the waveform or signal stream is defined in accordance with a logical matrix of values corresponding to the F2F or phase shift code formats used.

Abstract: ABSTRACT     A percussive tool is provided with a bit which comprises a shank, by which the bit is held in the tool, and a flexible blade made from a springy metal such as bainitic steel or phosphor bronze. 1.5mm  has been found to be a particularly satisfactory thickness for the tip portion of the blade.   Deposits of plaster, cement, caked oil and other deposits all of which can be highly resistant to removal by rigid-bladed bits from surfaces on which they have become hardened have proved surprisingly easy to remove using a springy metal blade.   The new blade is also very effective in removing tiles which have been cemented to a surface.

Abstract: ABSTRACT OF THE DISCLOSURE           A portable programmer is disclosed for programming and' testing a multiple rate meter such as an electronic time-of-day meter system.  The portable programmer includes a quartz crystal controlled seven-day clock.  A time comparator is driven in synchronism with a signal which drives the clock in the time-of-day meter.  When the time of the time com-parator is equal to that of the programmer's timer, a compare signal is generated to switch the time in the meter to its standard time base.  A programmable read-only memory in the portable programmer stores a plurality of different programs, each of which can be selectively read into the time-of-day meter.  The output of the programm-able read-only memory is read out and compared with the time generated by the time comparator.  When a comparision exists an output is generated to a program comparator which compares the control output of the time-of-day meter with the control output signal from the portable programmer, and if a comparision exists an indication is given indicating that the program has been properly read into the time-of-day meter. A method of programming and testing a multiple rate metering system by using the portable programmer is also disclosed.
