Title: Electrolyte for a double-layer capacitor
Inventor: DREISSIG DIRK
IPC: H01G11/42
Filed: 2009-11-25
Abstract: An electric double layer capacitor that contains at least one electrochemical cell is provided. The cell contains electrodes (e.g., two electrodes) that each contain a porous matrix of electrochemically-active particles (e.g., carbon). An aqueous-based electrolyte is disposed in contact with the porous matrix. In accordance with the present invention, the electrolyte is provided with an anionic polymer that serves as binding agent for the electrochemically active particles and thus reduces electrolyte loss, especially at higher temperatures. Because the polymer is anionic in nature, it is generally hydrophilic and thus can retain its binding properties in the presence of water. The anionic nature of the polymer also allows it to remain stable in the presence of a corrosive polyprotic acid, which is employed in the electrolyte to enhance charge density. Thus, as a result of the present invention, a capacitor may be formed that is capable of exhibiting good electrical performance (e.g., high capacitance and low ESR), even at high temperatures (e.g., 70°C and above).

Abstract: 1,107,177. Frequency modulation; data transmission systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. 3 March, 1967 [3 March, 1966], No. 10069/67. Headings H3R and H4P. A frequency modulator, Fig. 5, suitable for use in the transmission of binary data comprises a low-pass filter 16, a control circuit 18, an oscillator 28, and a frequency divider 30, the filter removing high-frequency components which would cause intermodulation distortion. In the circuit shown the multivibrator 28 has a centre frequency of twice the desired output frequency, and the frequency divider 30 divides this frequency by 2; this reduces the requirements of the filter 16. The input circuit 10 includes a pre-emphasis circuit 14, and the control circuit 18 includes means for adjusting the centre frequency and frequency deviation of the oscillator. The output passes through a vestigial sideband filter 34 which removes most of the upper sideband thereby allowing a higher rate of data transmission for a given bandwidth. Receiver circuit. Fig. 9.-The input signal is applied to a limiter 40 which has the effect of restoring the upper sideband, and then passes to a circuit 42 which responds to the zero crossings of the signal. The output of this circuit is passed to a filter 44 and a de-emphasis circuit 46 of the feedback type. The signal is now of the three-level type, extreme values of amplitude corresponding to a binary one and the median value to binary zero. This feeds a decision circuit 48 which converts the three-level signal into a binary output by means of overlapping level detectors 52 and 54. Clock signals.-When clock signals are required the filter 16 of Fig. 5, is replaced by a filter-trap combination (70, Fig. 13, not shown), the filter of which comprises a duo-binary lowpass network and the trap of which comprises a network responsive to half the repetition rate (bit period) of the binary data. The filter trap provides one input to an OR gate (72) feeding the control circuit 18, the other input to the gate being a clock signal operating at a frequency corresponding to half the bit period. At the receiver the clock signal is recovered by a tuned circuit having a high Q at the bit period rate, Fig. 14 (not shown).

April 5, 1933, No. 10204. [Class 122 (iii).] A three cylinder, three crank, tripleexpansion engine has two consecutively operative cylinders, the H.P. and M.P. or the M.P. and L.P., operating on the Woolf System. The second or low-pressure cylinder of the Woolf group has main piston-controlled exhaust ports, and an interstage receiver, which may be heated, is arranged between the Woolf group and the other cylinder of the engine. The angle between the cranks of the Woolf cylinders is between 120-180‹, preferably 150‹. The crank of the other cylinder bisects the exterior angle between the cranks of the Woolf cylinders. Any known type of valve may be used such as piston valves, slide valves (balanced or unbalanced), or poppet valves. Each valve may perform one or more functions. Combination of types may be used. Klug, Hackworth, Stephenson, rotary cam &c. gears may be used. In the construction as shown in the Figure, the H.P. and M.P. constitute a Woolf pair ; the L.P. cylinder is independent. The annular exhaust channel of the M.P. cylinder is enlarged to form a receiver between the M.P. and L.P. cylinders. A separate receiver may be employed. The M.P. cylinder is of semiuniflow type. The L.P. cylinder has pistoncontrolled exhaust ports. The exhaust passage G is an incomplete annulus, and the annular passage B is flattened to reduce the overall engine length. The M.P. cylinder may be a pure uniflow or a semi-uniflow one. In a modification, the H.P. cylinder is controlled by an independent piston valve. The M.P. and L.P. are controlled by a common slide valve ; the L.P. is a uniflow or semi-uniflow cylinder. The admission and exhaust of the whole engine is controlled by two slide valves and the piston or pistons controlling the terminal cylinder ports.

Abstract: 1,103,731. Automatic control of speed. BROOKHIRST IGRANIC Ltd. March 11, 1965 [March 13, 1964], No.10358/65. Heading G3R. An electric motor 5 is controlled in speed and angular position in relation to reference pulses 10 by a system in which the time for a given count of reference pulses is compared with that for a like count of motor speed pulses from a tachogenerator 11, and any difference is arranged to energize one or the other of two control windings in a magnetic amplifier 7 controlling the field of a generator which powers the motor. Coarse speed control is effected by two further control windings on the magnetic amplifier which are supplied with square pulses from 8 and 9 of constant magnitude and duration, but at a frequency corresponding to that of the reference oscillator 10 and tachogenerator 11 respectively. The output of the counters 12, 13 is a signal which changes from 0 to -10 volts at the end of each count (e. g. 4), and this is supplied to pulsers 14, 15 together with relatively high frequency square "clock" pulses from a multi-vibrator 16. The output of 14 and 15 is square pulses displaced relative to each other by an amount corresponding to increments of angular error. Comparison is made at 17, the output of which is applied to a five position register 18. This stores a single information "bit" which is transferred between the positions by the comparison device 17. If no error exists the "bit" is in store III and neither control winding is energized. If the motor lags slightly the "bit" is transferred between II and III, the relative durations in each being indicative of the average phase displacement; the appropriate control winding is energized when the bit is in I or II (lagging) or IV and V (leading error). Greater errors cause the "bit" to move between I and II (or IV and V), or finally remain continuously in I or V. The electronics are fully described, and comprise transistor multi-vibrators and bistable or mono-stable circuits Figs. 2a, b, c (not shown). The tachogenerator comprises a magnetic impulse wheel.

Abstract: 668,451. Fluid-actuated valves. SHELL REFINING & MARKETING CO., Ltd. April 28, 1950, No. 10529/50. Class 135. A pressure regulating valve for limiting the fluid pressure at a delivery point in a pipe line, and applicable, e.g. to aircraft fuelling equipment, comprises a valve member 3 coacting with a seat inclined, e.g. at 45 degrees, to the direction of flow, and having upstream and downstream stems 4, 5 each provided with a balancing diaphragm 7, 8 whose area is substantially equal to that of the valve member. The diaphragm 8 is subject to a pneumatic control pressure in a chamber 10, valves 18, 19 and a pressure gauge 20 facilitating adjustment of the pressure, whilst the diaphragm 7 is exposed on its lower face to the pressure at the delivery point. This pressure is transmitted through a damping ball valve 14 which permits free flow towards the diaphragm but a restricted flow in the opposite direction. In a modificaticn, pistons are used in place of the diaphragms and an adjustable spring load takes the place of the pneumatic control pressure. Also, the delivery pressure acts on a smaller piston which abuts the piston on the upstream stem, and the ball valve 14 is replaced by an adjustable needle valve. In a further modification, the loading spring acts on a plunger which has a hydraulic link with a portion of the piston on the upstream stem, the arrangement being such that the spring receives a lesser deflection than the piston. Instead of the diaphragm or piston on the downstream stem being loaded by air pressure or by a spring, it may be subjected to fluid pressure derived from a point upstream of the valve.
