Abstract: ENERGY CONVERSION SYSTEM         Abstract A system  is disclosed  for  converting  one form of energy into an alternate form of energy by means of a low-temperature process.  A liquid flow loop with two vertical columns  that are  interconnected at the top and bottom circulates a fluid.  A convective flow of this fluid is established by heating the fluid in one of the columns and cooling  the  fluid  in  the other column to establish a weight  differential  between  the  fluid  in  the  two columns.  An electric generator is placed on this loop so that, as the fluid flows through the loop and through the generator electrical energy is generated.  This electrical energy is used to electrolize a second fluid, such as a solution of sulphuric acid, into gasses such as hydrogen and oxygen.  The gasses so generated are used to increase the rate of flow of the fluid, and consequently the rate of electric energy production,   In one embodiment,  the gasses are injected into the rising column of the fluid to increase the weight differential between the fluid in the two  columns  and  enhance  the  convective  flow  of  that fluid.  These gasses, which contain chemical energy, are then removed from the loop at the top of this column. Alternatively,  the  gasses  can  be  accumulated  at  high pressure, and the pressure used to inject a volatile fluid into the loop.

Abstract: ABSTRACT OF THE DISCLOSURE       An apparatus and method for use in filling a valve bag eliminates sifting of product during the filling process.  A filling nozzle is inserted into the valve of a bag to be filled.  A flow of particulate material is provided through the filling nozzle and into the bag.  When the bag is full, the flow of particulate material is terminated.  A blast of high pressure air is then introduced into the nozzle in order to clear the nozzle of any residual particulate material therein.  A low pressure blast of air is introduced between the nozzle and the filling valve to suspend any particles present in the filling valve after the nozzle has been cleared by the high pressure blast.  A vacuum is introduced into the nozzle to suck any suspended particles out of the filling valve after the low pressure blast has been introduced.  A boot can be inflated around the nozzle to seal the nozzle within the bag valve before filling the bag.

Granted: 1987-01-20
Abstract: ABSTRACT:         Differential pulse code modulation transmission system comprising a transmitter and a receiver.  In the transmitter there is subtracted from an informational signal x(n) to be transmitted a prediction signal y(n) for the purpose of generating a difference signal e(n), which is quantized and converted into a quantized difference signal in a quantizing arrangement 6.  This difference signal is applied to a prediction circuit 7 for generating the pre-diction signal.  It is also transmitted to the associated receiver.  In that receiver a similar prediction signal is generated by means of a similar prediction circuit,  which prediction signal is now added to the received quantised difference signal.  In order to limit the influence of transmission errors in this transmission system, without an excessive increases in equipment, the quantised differ-ence signal is applied in the transmitter and in the receiver to a cascade arrangement of a non-linear network 16 and an auxiliary prediction circuit 17, which produces an auxiliary prediction signal.  Before the quantised differ-ence signal is applied to the prediction circuit the auxiliary prediction signal is first added thereto.

Abstract: SPECIFICATION FOR PATENT APPLICATION            Title        "Electrical Monitoring Systems"                     ABSTRACT    Electrical systems, especially elongate heating systems, include means for monitoring circuit continuity. The systems comprise a switching device, e.g. a thermo-stat, as well as a circuit breaker.  When the switching device is on, a relatively high current passes through the circuit and when it is off, a small controlled residual current flows in the circuit, and a current-detecting device signals when a discontinuity causes the current to drop below the expected value for the residual current.  Preferably the switching device is placed so that the heater is at a positive potential even when the switching device is off, and a ground fault indicator is used to compare the currents in the two legs of the circuit and to signal when a ground fault causes the currents to differ.

Abstract: ABSTRACT             Disclosed is a method of making a dimensionally stable composite board product made from a mixture of parti-cles or a cellulose material and binder and a composite board so produced by such method.  Dimensional stability is in reference to the resistance to thickness swelling when the board is subjected to high humidity or moisture conditions. The method and composite board displaying the attribute of improved dimensional stability involves subjecting the particles of cellulosic material to a pressurized steam treatment and then making the composite board under heat and pressure.  When compared to conventional composite board that has not been subjected to the pretreatment, the difference in thickness swelling is significant.
