Title: Thermoelectric devices
IPC: H01L35/20
Filed: 1970-09-22
Abstract: 1325888 Thermoelectric devices B F HALL JNR 22 Sept 1970 45104/70 Heading H1K At least one of the junctions of a thermoelectric device is arranged to have a zero thermoelectric power (Seebeck coefficient) over its operating temperature range. The junction may comprise a single junction of suitably selected materials or a plurality of different junctions connected in series, the intermediate junctions being at ambient temperature. The junction may be used as the measuring junction or the reference junction in measuring instruments, or a device with both hot and cold junctions so arranged may provide a constant voltage source. As shown, Fig. 2A, a Chromel/Alumel (Registered Trade Mark) thermocouple connected in series with a Ni 49% Fe/stainless steel thermocouple provides a characteristic which has zero thermoelectric power over a considerable region about ambient temperature and at higher temperatures has the same thermoelectric power as a Chromel/Alumel thermocouple for which it can therefore be substituted, the scale points of a calibrated measuring instrument being increased by about 400 F. A single thermocouple of Ni 49% Fe/Constantan has a similar characteristic with a high temperature thermoelectric power the same as that of an Fe/Constantan thermocouple for which it may therefore be substituted. As shown, Fig. 4, a thermocouple with reference temperature compensation comprises a hot junction E/F of FE/Constantan and a reference junction assembly comprising an Fe/Ni 49% Fe junction G/H connected in series with eight Alumel/Ni junctions J/K. The reference junction assembly is heated to a temperature at which it exhibits a constant thermoelectric EMF (zero thermoelectric power), accurate control of the temperature being unnecessary since this characteristic is maintained over a considerable temperature range. Similar constructions may comprise an Fe/ Constantan hot junction with a reference junction comprising a single Fe/Ni 49% Fe junction, a Chromel/Alumel hot junction with a reference junction comprising two series connected Ni/Ni 49% Fe junctions, or a Chromel/ Constantan hot junction with a reference junction comprising three series connected Ni/Ni 49% Fe junctions. A thermocouple comprising Fe 3% Ni 0À5% Mn/Ni has a characteristic with two portions of constant thermoelectric EMF (zero thermoelectric power) so that if it is operated with its hot and cold junctions within these temperature ranges a constant output voltage will be produced. A similar voltage source, Fig. 8, comprises four series connected Chromel/Inconel (Registered Trade Mark) junctions as the hot junction and a single Fe/Ni 49% Fe junction as the cold junction. The characteristics of the materials are substantially matched at low temperatures so that the junctions at ambient temperature have no significant effect on the output voltage. Design considerations for selecting suitable combinations of materials are discussed.

Filed: 1970-11-03
Abstract: 1333059 Plexifilaments E I DU PONT DE NEMOURS & CO 3 Nov 1970 52244/70 Heading B5B A plexifilament made by "flash-spinning" a solution of a non-crystalline (as determined by X-ray diffraction) thermoplastic synthetic organic polymer comprises a plurality of fibrils positioned parallel to the plexifilament axis and interconnected at their ends to form a three-dimensional plexus, the fibrils being less than 5Á thick and composed of film-fibrils less than 1Á thick which are oriented substantially only along their longitudinal axes. The plexifilament has a minimum surface area of 2m<SP>2</SP>/g, a minimum tenacity of 0À1 gpd, a minimum free fibril count of 50/thousand/0À1 mm. length and a density within 2% of that of the solid material from which it is made. The solvent should have a b.p. below the flow temperature of the polymer, be inert and have sufficient solvent power to form a single phase solution at the extrusion temperature and pressure but still form a twophase solution at the same temperature when the pressure is released. As described a 10-40% polymer solution within 40‹C of the solvent critical temperature and above the two-phaseboundary at this temperature by e.g. 200-300 p.s.i., is extruded first into aregion about 200p.s.i. below said boundary to produce a two-phasesolution which is then "flash-spun". The polymer may be a polycarbonate, polysulphone, PVC, polystyrene, or polymethylmethacrylate (solvent methylene chloride) or polyacrylonitrile (solvent aqueous acetonitrile). The power of the solvent may be adjusted by additives, e.g. fluorotrichloromethane on 1, 1, 2- trichloro-1, 2, 2-trifluoroethane in the case of methylene chloride.

Title: Transmission lines interconnecting high speed logic circuits
IPC: H03K19/018
Filed: 1971-04-19
Abstract: 1340770 Logic driver HONEYWELL INFORMATION SYSTEMS Inc 19 April 1971 [5 May 1970] 23436/71 Heading H3T A logic driver is connected to a transmission line via a network of two parallel branches each being connected serially between the output of the logic driver and the transmission line, the impedance of one branch being low relative to the impedance of the other branch when the logic driver is in one state and high relative to the other branch impedance when the logic driver is in its other state, the other impedance being equal to the characteristic impedance of the transmission line. The driver 10 may include a logic stage with a transistor 20. The one impedance may be a diode or diode connected transistor (Fig. 2b, not shown) so the full voltage of the driver output may be applied to the line 62 and so to a logic circuit 60 but in the low voltage state of the driver the diode is reversed biased to leave an impedance Z o  to match the driver end of the transmission line and terminate reflections from the other end thereof. The logic circuit has a high input impedance so causing the transmission line to be effectively open circuited thereby obtaining a voltage at the input to the circuit 60 twice that of the output voltage of the driver 10. A NAND logic circuit may replace transistor 20. The resistor Z L  is selected to prevent overload of transistors 30, 34.

Title: Recovery of chemicals from waste gases
IPC: B01D5/00
Filed: 1971-04-26
Abstract: 1348337 Condensation of vapours; removal of pollutants from waste gases DOW CHEMICAL CO 26 April 1971 11405/71 Heading B1B A stream of waste gas containing condensable pollutants and water-vapour is brought into contact with the surface of a condenser maintained at a temperature of 0‹C. or below, the surface being supplied with a watermiscible liquid so that it flows as a film over the surface and prevents the formation of ice thereon; the gas stream, freed from condensate, is vented to the atmosphere. The ice-preveting liquid may be a lower alkanol, alkoxy alkanol, or glycol. If the condensate is immiscible with the ice-preventing liquid, the latter is separated by gravity and re-used in the condenser, but if it is miscible with the condensate, fractional distillation may be resorted to in order to recover the ice-preventing liquid. In an example, a gas stream containing nitrogen (88%), water (3.2%) and chlorinated hydrocarbons (8.9%) at 38‹C. enters the tube side of a vertical tube and shell condenser, the shell of which is supplied with liquid ammonia at -41‹C.; and an aqueous solution of ethylene glycol (60%) is fed into the tube so that it flows down and covers the wall of the tube, the flow of gas and glycol being concurrent. The effluent gas, leaving the condenser at -21‹C., contained only 0.6% of chlorinated hydrocarbons. The glycol solution is separated from the condensed chlorinated hydrocarbons by phase separation. The chlorinated hydrocarbons were primarily ethylene dichloride and smaller amounts of ethyl chloride, cis- and trans-dichloroethylene and #-trichloroethane. The waste gases from direct and indirect fired driers and waste burners may be treated by the condensation process before being vented to the atmosphere.

Inventor: LOMP GARY
IPC: H04B17/00
Filed: 1996-06-28
Abstract: A multiple access, spread-spectrum communication system processes a plurality of information signals received by a Radio Carrier Station (RCS) over telecommunication lines for simultaneous transmission over a radio frequency (RF) channel as a code-division-multiplexed (CDM) signal to a group of Subscriber Units (SUs). The RCS receives a call request signal that corresponds to a telecommunication line information signal, and a user identification signal that identifies a user to receive the call. The RCS includes a plurality of Code Division Multiple Access (CDMA) modems, one of which provides a global pilot code signal. The modems provide message code signals synchronized to the global pilot signal. Each modem combines an information signal with a message code signal to provide a CDM processed signal. The RCS includes a system channel controller coupled to receive a remote call. An RF transmitter is connected to all of the modems to combine the CDM processed signals with the global pilot code signal to generate a CDM signal. The RF transmitter also modulates a carrier signal with the CDM signal and transmits the modulated carrier signal through an RF communication channel to the SUs. Each SU includes a CDMA modem which is also synchronized to the global pilot signal. The CDMA modem despreads the CDM signal and provides a despread information signal to the user. The system includes a closed loop power control system for maintaining a minimum system transmit power level for the RCS and the SUs, and system capacity management for maintaining a maximum number of active SUs for improved system performance. <IMAGE>
