Title: Automatic switching network
IPC: H04Q3/52
Filed: 1968-11-27
Abstract: 1,207,559. Automatic exchange systems; transistor gating circuits. INTERNATIONAL STANDARD ELECTRIC CORP. 27 Nov., 1968 [5 Dec., 1967], No. 56281/68. Headings H3T and H4K] In a multi-stage switching network through which paths are selected by a one at a time search over a plurality of self-seeking paths, the crosspoints employed in the switching matrices are MOS, PNPN diodes. The one at a time searches are controlled by RC networks such as 82, 83 in the usual way utilizing rampfronted, end-marking potentials, c.f. Specifications 1,021,816, 963,319, 960,960. The " control electrode (i.e. the electrode connected to the MOS layer formed on the basic PNPN diode, Fig. 2, not shown) of each diode is connected to an enable lead XE which is usually common to all the diodes in a vertical of the matrix. By marking this lead with suitable potentials a " free " diode can be effectively looked-out of a search or a free but normally locked-out diode may be enabled in order that, for example, dead-end paths can be ignored or preferred paths be searched first (Figs. 6, 7, not shown). The electrode is supplied with positive busy potential from the link over the PI leads whenever it is selected for use in a call. The latter busying may be effected with the aid of transistor gates (Fig. 8 or Fig. 9, not shown). In order to override the busy condition, normally off transistor 114 is turned on by a pulse 116 whereby the potential at point XE is made sufficiently negative to allow device 111 or 112 to turn-on if a firing voltage appears thereacross. When the pulse is removed, 114 turns off and the disabling positive potential is reconnected to the gates of the crosspoint devices. In a further arrangement (Fig. 12) a plurality of FETs and the crosspoint MOSPNPN devices are incorporated in an integrated circuit. Normally on FETs 141, 142 serve as clamps providing known voltage drops and temperature equalization and in addition 142 maintains an inhibiting positive potential on the gates of the MOS diodes 152, 153. An Enable pulse applied to FET 155 turns it on whereby 146 is turned-off and the positive bias potential is therefore removed. If now 152 or 153 fires due to the appearance of a firing potential thereacross, the resultant positive potential on vertical bus 147 turns-on 143 and thus 141 and 146 are turned-off. Further Enable pulses have no effect until diode 152 or 153 is restored at the end of the call.

Title: Method and apparatus for continuously monitoring carbon dioxide
IPC: G01N31/00
Filed: 1969-11-19
Abstract: 1,235,820. Gas analysis. WESTINGHOUSE ELECTRIC CORP. Nov.19, 1969 [Jan.9, 1969], No.56651/69. Heading G1B. A method for continously monitoring carbon dioxide in a gas stream comprises passing the gas stream through a heated reactive bed of at least one alkali or alkaline earth metal hydroxide in a reactor 12 at a rate such as to replace carbon dioxide in the gas stream by a corresponding amount of water vapour, the increase in water vapour content within the gas stream being measured to determine the original carbon dioxide content. In one form of apparatus, a pump 18 is used to draw a gas stream through the apparatus, its flow-rate being indicated by a flow-meter 16. Gas is admitted to an inlet 56 from which it passes through a spiral path in a desiccant container 22 e.g. containing calcium chloride or anhydrous calcium sulphate to minimize the moisture content of the gas stream to a constant predetermined value the gas then passing to the reactor 12 through an inlet tube 40. The reactor is preferably of stainless steel and is embedded in insulating material and heated by a heater wire 82. Bores are formed in the reactor 12 and these are filled with the alkali er alkaline earth metal hydroxide and arranged so that the gas follows a tortuous path through the reactor from whence it leaves via a tube 44 to pass to the hygrometer and subsequently to the flow-meter 16, pump 18 and discharge to the atmosphere. The hygrometer is of known form and may be calibrated to read directly in carbon dioxide content of the original gas stream. In place of the desiccant container 22 a thermo-electrically cooled condenser type of de-humidifier may be used, or as a further alternative a second hygrometer may be employed to measure the original water vapour content of the gas stream, this being compared with the measurement made after reaction has occurred.

Abstract: 1,242,239. Variable displacement pump control. SPERRY RAND CORP. Dec. 3, 1968 [Dec. 4, 1967], No. 57193/68. Heading G3P. Excess pressure in the discharge line 2 of pump 1 acts via line 6 to raise spool 10 to connect line 6 to line 13 whereby increased pressure acts via bore 14 to depress piston 34 to decrease the pump displacement. Spool 27 follows movement of piston 34 and has a land 32 which meters flow from line 11 to exhaust 7 to set up a pressure in line 25 which is a function of the pump displacement. This pressure acts on piston 21 to augment spring 20 in opposing upward movement of spool 10. Relief valve 16 limits the maximum value of the feedback pressure and the latter ensures that the power to drive the pump remains constant. Line 13<SP>1</SP> ensures pressure balance across spool 27. In Fig. 2 (not shown), spool 27 is replaced by a rotary metering valve driven by piston 34 through a rack and pinion; alternatively, line 13 connects with port (46) and the rotary valve acts additionally as a motor to control pump displacement (piston 34 being omitted). In Fig.3 (not shown), the Fig. 1 arrangement is embodied in a swash-plate pump structure.
