Patent EE-200100100-A (EE)
Inventor: YUAN JIREN
IPC: H03M1/18
Filed: 1999-08-19
Abstract: The demand on very high resolution A/D converter can be eliminated by using the invented floating-point A/D converter when the resolution is merely used for covering the signal dynamic range rather than the quantization accuracy. This can be achieved by producing m amplified analog signals with amplifications 2(i-1)k where k=constant and i=1, 2, . . . m. The largest linearly amplified signal will be selected by a logic circuit (after sampling) and converted into an n-bit digital data code by an A/D converter. In the same time, the logic circuit produces an m-bit logic flag code. The n-bit data code (u), the m-bit logic flag code (v) and the constant k are combined to form a final digital output uvk with n+(m-1)k bits. In this way, the resolution and dynamic range can be designed independently. Unlike the know logarithmic amplifier solution, the floating-point A/D converter give a linear digital code output directly without using any look-up table. For large and small signals, the effective resolutions are kept constant (or quasi-constant to be accurate). It is also very useful to work with a small input range imposed by a low power supply voltage since its virtual input range is much larger than the actual one. As an A/D converter, its accuracy distribution along the signal amplitude is more rational, an advantage similar to that of a floating-point number representation.

Title: Improvements in Apparatus Suitable for Generating and Supplying Acetylene Gas.
Filed: 1898-09-01
Granted: 1899-07-22
Abstract: 18,741. Wise, W. L., [Wilson, F. C.]. Sept. 1. Acetylene.-Apparatus in which water is automatically driven away from the carbide as the pressure of generated gas increases. The tank A is divided by a partition a into two compartments, the lower of which is further divided into a water supply chamber B and a gas-generating chamber C. The latter contains a drawer D which can be inserted or withdrawn through the door C'. The door is afterwards closed in an airtight manner. The drawer contains one or two slightly-inclined but parallel carbide screens or gratings d, d', beneath which are holes d<2> through which water can enter, as it rises in the outer chamber C. The water passes from the chamber B to the chamber C by a tube B<1> having a valve b. The level of the water in the chamber B is regulated by an adjustable vent tube B<4>, having an indicating-finger on the exterior passing over a graduated scale. The tubes b<5> and G lead to the air outside the apartment in which the apparatus is placed. In use, water passes to the generator, and acetylene is generated. This passes through the constricted opening C' to the tube C<2>, from which it passes through the check valve C<3> to the bell E, and thence through openings f<3> to the mixing and gas cooling and drying chamber F having depending walls f, f<2>. Finally, it escapes by the tube F<1> to the burners &c. As gas is developed, the bell rises higher and higher, thereby raising in succession from the cover.f the weights E', E', E<3>, and E<4>. The pressure in the system increasing, the water is driven away from the carbide in the generator, and, should the water be driven below the opening to the safetytube G, the excess gas will escape by that tube. To develope a sudden large supply of gas for use while re-charging the generator, a small drawer H is filled with carbide and slid into the generating-chamber. Water is then allowed to flow directly thereupon from the water tank I. This tank has a bell I', and air-inlet i<2> having a non-return valve, and an air - outlet pipe i<3>, also having a non-return valve. The outlet pipe leads to the lower part of the generator. When it is desired to clear out the generator, the bell I is reciprocated, whereby any residual gas in the generator is forced outwards through the escape tube G.

Granted: 1900-02-03
Abstract: 5923. Philipson, W. H. March 18. Charcoal.-Wood is treated in kilns so as to obtain charcoal, tar, acetic acid in the form of calcium acetate, and waste gases which are employed for heating the air required in the kiln. There are, in the arrangement shown, four brickwork chambers a, a', a<2>, a<3>, surrounded by an outer wall d and packed with a suitable non-conducting material. Each chamber is provided with a charging-opening b, and three other openings e, f, g, all of which can be closed by covers c, l. The openings e, f lead to the top of the chamber, while the openings g lead to the bottom. Near tho bottom are discharge openings s having doors t. A number of elbow tubes i, j<1>, k are provided for connecting purposes. Air enters a column m through a tube o, and passing up vertical tubes is heated by a surrounding flame caused by igniting the gas from the tube p. The hot air, in the particular stage of the process shown in Fig. 1, passes by an elbow tube i to the opening f in the first chamber a of the series, namely, that one in which the carbonizing process is most nearly finished. The vapours and gases are drawn off from the lower part of the chamber by the tube g, and, passing through the connection k, enter the second chamber through the opening e. Similarly they pass through the third chamber a<2>, and thence bv the connection j<1> they pass to a tube j. The fourth chamber a<3> is meanwhile being discharged and re-charged. The gases &c. are led to a tar separator, and thence to a column q, up which they pass through a packing of lime by which the acetic acid is retained, forming calcium acetate. The waste gases leave the top of the column by the tube u, and are led to the airheater m for combustion, When the wood in the chamber a is completely carbonized, that chamber is cut out, a<1> then becoming the first chamber, a<2> the second, while a<3> is put in as the last, the connecting-tubes being altered for the purpose.
