Title: Radiation absorbing compositions, methods and articles incorporating such compositions
Inventor: KELLER KEITH A
IPC: C07C215/82
Filed: 2007-06-07
Abstract: Infrared (IR) radiation absorbing compounds of metal or metalloids with ligands are beneficial for many applications. Schiff base biquinone (SBB) ligands surrounding a metal or metalloid center may be used for laser welding applications, as one example, wherein effective infared radiation absorption and heat resistance are required. These compounds may be known as Schiff base biquinone metal complexes (SBBC's). The compositions and methods of this invention provide examples of many different NIR absorbing compounds that exhibit high NIR absorbing strength, good thermal stability, and relatively low visible color. The IR absorbing compounds may employ one or more of the following elements: Si, Zr, Bi, Sb, Ce, Cs, K, Mo.

Title: Apparatus for and a method of purifying waste liquor
IPC: C02F1/04
Filed: 1972-03-03
Abstract: 1389566 Treatment of waste liquors from coking plants USS ENGINEERS & CONSULTANTS Inc 3 March 1972 [3 March 1971] 10134/72 Heading B1B [Also in Division F4] Aqueous waste liquor containing corrosive salts, produced by contacting hot coke oven gas with aqueous liquor and then separating tar by decantation, is treated to remove residual tar in vessels 28 and 66, is freed from phenols in extraction tower 68 and is then diluted with water from line 15 and pumped through the tubes of heat exchanger E1 the shell side of which is supplied with steam at a temperature of 200‹F and a pressure of 13.8 psia, which has been liberated in a coke quenching operation and is supplied to the heat exchanger through particle deentrainment vessel VI and line L14; the heated liquor is partially vaporized in evaporator EVI, and the vapour may be passed to condenser E4 to obtain desalinated aqueous liquid which, together with the steam-condensate collected in drum V2, may be freed from NH 3 , CO 2  and H 2 S in distillation tower 46 and then used to quench coke, or used as boiler feed water. The steam in line L14 is sucked into the shell side of heat exchanger El by a steam jet J1. The concentrate leaving the base of evaporator EV1 is recycled to the tubes of heat exchanger El. The vapour from EV1, which contains CO 2  and H 2 S, may be passed to the shell side of heat exchanger E2 where it heats some of the concentrate from EV1 and some of the recycled concentrate from evaporator EV2; the heated concentrate then undergoes partial vaporization in EV2. The remainder of the concentrate from EV2 is passed through heat exchanger E3 and restrictive orifice 71 into evaporator-crystallizer EV3. Heat exchanger E3 is supplied with the vapour from EV2. The vapours from EV3 flow to condenser E4. The mixture of salt and saturated solution leaving EV3 passes through filter F1, and the filtered solution is pumped back to EV3. A backward flow system is described, in association with Fig. 5 (not shown), wherein the steam from the coke quenching operation is passed to the heat-exchanger connected to the evaporatorcrystallizer.

Patent GB-587939-A (GB)
Title: Improvements in or relating to multi-channel electrical pulse communication systems
IPC: H04J3/04
Filed: 1944-05-26
Abstract: 587,939. Multiplex signalling ; pulse modulation. STANDARD TELEPHONES & CABLES Ltd., and LEVY, M. M. May 26, 1944, No. 10305. [Class 40 (v)] A multiplex signalling system employs as a distributer a delay network traversed by a synchronising wave or pulse, and means are provided for eliminating effects due to distortion of the wave or pulse as it traverses the network. As shown in Fig. 2, a pulse originating in the reciprocally-coupled valve pair 42 is fed to the output line 32 through a diode 35, vnd is also fed to the network 1 provided with toppings 5 ... 9 leading to the signal channels 13 . . . 17, which are thus brought successively into use. When the original pulses are rectangular, their vertical sides become more and more inclined as they proceed along the network, but their width at half their full amplitude remains fairly constant. If, therefore, the distorted pulse is applied to an amplifier 10 with a suitable grid bias 11, the valve will begin to pass current at the correct moment. The amplifier should preferably be a pentode valve with a high resistance 12 inserted in its grid lead. A diode may be connected between the grid and earth. The resulting pulse in the anode or cathode circuit is used with or without differentiation to open the transmitting or receiving apparatus 13 . . . 17 in the relevant channel. In the channel 15, the distorted pulse at tapping 7 is applied to the grid of a back-biassed valve 19 reciprocally coupled to a valve 20. The valve 19 is unblocked by the pulse from tapping 7, thus blocking the valve 20 for a time dependent on the bias on its grid 22. If a microphone 24 is inserted in the bias circuit, the duration of negative pulses generated across the cathode resistor 26 is dependent on the momentary speech voltage. These pulses may be differentiated by the circuit 28, 29 and the resulting leading pulse suppressed by the diode 31, the positive trailing pulse 33 being passed through a diode 38 to the common output line 32. The multi-vibrator 42 may be as described in Specification 587,940, and may be synchronized by a pulse from the far end of the network 1 fed back through a shaping amplifier 46. In a modified arrangement, Fig. 3, the valve pair 42 feeds pulses to the network 1 as before, and tappings, 5 ... 8 on the network are connected to the reversal channels 13 ... 17. A further oscillator 48 operates at a frequency equal to that of 42 multiplied by half the number of channels and is synchronized therewith as described in Specification 578,690. Its output is converted to square pulses 50, 51 in phase opposition in the shaping circuit 49, and one set is supplied to the channels of odd number and the other to the channels of even number. The delayed pulses from the network 1 and the pulses 50, 51 from the device 49 are applied to valve circuits in the respective channels 13 ... 17 in such fashion that a channel is rendered operative only when the pulses are superposed. Specification 587,941 also is referred to.

The outlet has vertical vanes 25 to straighten the flow and the tube 22 has slots 24 of such a width that over 50% of the tube's circumference is open to atmosphere. Back-siphonage, even under a pressure of 28 inches of mercury, is thus prevented.
