Title: Process for removing nicotine from tobacco material
Inventor: MOSER GLENN PHILIP
IPC: A24B15/24
Filed: 1963-01-02
Abstract: A process for denicotinezing tobacco comprises treating tobacco with ammonia and steam to drive off in vapour form free nicotine and ammonia, condensing the vapours and heating the condensate to 95 DEG C to expel the ammonia which is recovered, treating the remaining condensate with aqueous sodium hydroxide solution to form a two phase liquid of sodium hydroxide and nicotine, removing the nicotine phase, and steam stripping the aqueous phase to remove residential nicotine, the vapours being condensed and recycled for further treatment with sodium hydroxide. Alternatively, the condensed vapours from the tobacco treatment (i.e. water, nicotine and ammonia) are steam stripped in the presence of sodium hydroxide to remove nicotine and ammonia, the ammonia is expelled and the nicotine and water vapours are condensed and treated with aqueous sodium hydroxide to form the two phase liquid described above from which the nicotine is separated.  The "bottoms" liquid resulting from the steam stripping processes may be evaporated to concentrate the sodium hydroxide which may be recycled.  Flow diagrams are shown of the two processes.

Title: Standard resistance thermometer
IPC: G01K7/22
Filed: 1969-01-02
Abstract: 1,246,154. Resistance thermometers. ROSEMOUNT ENG. CO. 2 Jan., 1969 [22 Jan., 1968], No. 349/69. Heading H1K. The main element of a standard resistance thermometer consists of parallel lengths 25, 27, 29, 31 (the middle of the runs 27, 29 is left out of the drawing) or platinum wire threaded through aligned holes in spaced insulator discs and connected in series to form a single "coil" by sharp-angled U-links 26, 28, 30, 32 at one end and at the other end by turns round the insulation 16 which hold the discs 15 apart. The U-links 28, 30 stand out further from the end disc 15 than the links 26, 32 so that adjacent links do not contact one another if accidentally bent. The insulator discs 15 and spacing insulators 16 are held together by a platinum wire 17 passing through axial apertures and being provided with blobs 21, 22 to retain the insulators. In use, measurement between this central wire and one end of the main element gives an indication of insulator leakage resistance. The assembly is mounted in one end of a sealed and gas-filled silica tube, the greater part of the tube being occupied by the lead-out assembly. Each end of the main element is connected by two small gauge wires 37A-40A to two lead-out wires. (Only two 37, 38 of the four lead-out wires can be seen in Fig. 6.) The use of small gauge wires gives high thermal resistance. The lead out wires pass through insulator tubes which hold apart further insulator discs. Details of the external connections to the thermometer are illustrated in Fig. 1 (not shown). To minimize radiation transmission along the thermometer the silica tube is externally sand blasted in its lead-out section, the insulator discs in the leadout section are roughened on the side away from the element and polished on the side facing the element, and the insulator discs in the element section are polished on both faces.

Title: Circuit arrangements for the generation of electrical pulses of variable duration
IPC: G01S1/02
Filed: 1944-01-07
Abstract: 579,853. Radiolocation ; valve circuits. STANDARD TELEPHONES & CABLES,Ltd. Jan. 7, 1944. No. 375. Convention date, Jan. 8, 1943. [Class 40 (v)] [Also in Group XXXVI] A variable width pulse, the leading edge of which is adjustable relative to a given instant and is suitable for use as a range marking step in a radiolocation cathode ray tube display, is produced by charging a condenser until a given potential determined by the grid-bias on a gas discharge tube, is reached, when the gas discharge tube, connected in shunt to the condenser, conducts and initiates the pulse which is terminated when a second discharge tube controlled by a synchronising signal is effective to discharge the condenser. A condenser C, Fig. 1, connected to a source of positive voltage B + through a charging resistance R is discharged by the gas-filled tube 11 at an instant determined by a synchronising pulse 26, Fig. 2, which may correspond to the transmitted pulse in a radio location system, and is applied to the grid of the tube 11. Alternatively synchronisation may occur at a particular instant on an applied sine wave 27 determined by the bias applied to the grid of tube 11 from the potential divider 32. After condenser C is discharged it charges up along curve 25 until it reaches a point such as 70 or 70a, determined by the bias applied to the grid of a second gas-filled discharge tube 12 from potential divider 42 at which that tube becomes conducting and shunts the condenser with resistance 20 and prevents further rise of voltage. The current flowing through tube 12 produces a pulse 72 across resistance 52 in its cathode circuit, the leading edge 71 or 71a of which is determined by the setting of potential divider 42, while the trailing edge 77 is determined by the discharge of condenser C by tube 11. In order to preserve a flat top to the pulse 72 when the width control potential divider is varied, the variable resistances 20 and 52 are ganged with the potential divider 42, or a limiting circuit may be connected to the output. As shown, the pulse output from terminal 19 is fed together with echo pulses such as 26a and 26b from the radiolocation receiver to the vertical deflecting plates 57, 58 of the cathode ray tube 60, a time base voltage from the sweep generator 62 controlled by the synchronising pulse being applied across the horizontal plates to produce the trace A-B. The step in the trace corresponding to the leading edge of the pulse is aligned by means of the potential divider 42 with the selected echo signal 26a the setting of the potential divider being then an indication of the range of the echo.

Abstract: 1,255,621. Pulse generators. SOUTH WALES SWITCHGEAR Ltd. 29 Nov., 1968 [4 Jan., 1968], No. 558/68. Heading H3P. [Also in Divisions H1 and H2] A capacitor discharge type pulse generator uses " divided switch " arrangement, Fig. 1, comprising a number of switches 8 which are constrained to operate in unison (e.g. by means of an insulating rod 7) and are arranged such that circuit elements connected across them are in a first series connection for one position of the switches and in a second series connection, with at least some of them reversed in polarity, in another position of the switches. The arrangement includes an assembly which comprises a plurality of substantially flat aligned parallel plates 1, 2, 3, 4 each provided with first, second, third and fourth terminals a 1 , b 1 , c 1 , d 1 , a 2 , b 2 , c 2 , d 2  &c. and a switch actuator rod 7 passing through the assembly of plates and carrying a switch arm 8. adjacent each plate for making connection between terminals such as a 1  and c 1  or b 1  and d 1  in the two positions of the switches. Movement of the switches from the positions shown in Fig. 1 to the positions where they interconnect terminals b 1  and d 1 , b 2  and d 2 , b 3  and d 3 , b 4  and d 4 , reverses the polarity of series connected rectifiers 6. The arrangement may be immersed in oil and mounted within a rectifier housing. In another embodiment, Figs. 4 and 5, the "divided switch " is connected such that it reverses the polarity of alternate secondary windings of a transformer so as to reduce the output from a maximum to zero (Fig. 5). Alternatively each transformer winding could be replaced by a number of complete rectifier sets. As another embodiment, the switch may be incorporated in a cascade rectifier generator of the Greinacher type (Figs. 2 and 3, not shown). Alternatively, it may be used in a high impulse voltage generator which comprises a rectifier/capacitor set c 1  (Fig. 6) in series with a further set (c 2 ) of series connected capacitors. One or both of the capacitor sets is interconnected by an arrangement similar to Fig. 1. The capacitor sets having been charged up, an impulse voltage appears across a resistor (R) when the polarity of one set is reversed.
