Title: Method and apparatus for the analysis of a gaseous mixture
IPC: H01J41/04
Filed: 1961-09-15
Abstract: 966,715. Gas moistures, determining constituents of. CANADIAN PATENTS & DEVELOPMENT Ltd. Sept. 15, 1961 [Sept. 21, 1960], No. 33107/61. Headings G1B and G1N. The constituents of a gas are determined by contacting the gas with adsorbent in a confined zone, raising the temperature of the adsorbent to desorb the constituents separately, and concurrently measuring the gas pressure. The amount of each constituent is recorded by operating at specific desorption temperatures an ionisation vacuum gauge to produce a recordable ion current correlated with the total pressure of the gaseous substance or with the partial pressure of a selected possible constituent. As shown in Fig. 1, an adsorbent 20 is situated within a chamber 10, a neck 15 of which is fitted with a low vacuum pump 12 via valves V1 or V3, and a titanium vapour high vacuum pump 13. The chamber may be immersed in a Dewar flash 50. The system is heated for several hours while exhausting the'chamber by pump 12. After exhaustion, valves V3 and V1 are closed and vacuum pump 13 is operated until the pressure reading given by an ionisation vacuum gauge on ion current recorder 32 is below 10<-10> mm.Hg. The adsorbent 20 is cleaned by flushing at 2400K. On cooling to room temperature or below gas is admitted through V2 continuously or batchwise such that the pump associated with gauge 14 maintains the pressure below 10<-7> mm. Hg, a portion of the gas being adsorbed. The temperature of the adsorbent 20 is raised at a controlled speed thus evolving the adsorbed gases and a pressure/temperature relationship is obtained on recorder 32. Gauge 14 may be a mass spectrometer. Adsorber 20 may be made of tungsten, molybdenum, platinum, rhenium, osmium iridium or vanadium and may be in filament, strip or disc form, either self-supporting or suspended as in Fig. 3, or as in Figs. 4,or 5 (not shown) wherein the adsorbent is in the form of one or more annular discs. A further preferred embodiment Fig. 6 (not shown) includes an ionisation gauge 14 adjacently disposed within the chamber. Specification 889,947 and U.S.A. Specification 2,958,774 are referred to.

Title: Communication system
IPC: G06F13/00
Filed: 1973-07-12
Abstract: 1377467 Digital data transmission; polling systems INTERNATIONAL BUSINESS MACHINES CORP 12 July 1973 [28 Aug 1972] 33206/73 Heading H4P  A communication system comprising a central station and a number of remote stations is characterized in that the central station includes : first polling means for polling the remote stations in a predetermined sequence, the time interval between successive polls being less than a time interval in which a response is received at the central station from a polled station; means for stopping polling when a response is received from any polled station; and second polling means, responsive to simultaneous responses from two or more polled stations, to repoll these stations, the time interval between successive repolls being at least equal to a time period in which a response can be received at the central station. In the first, fast, polling condition, address signals from generator 1 are fed via AND gate 2 to memory 5 and also via OR gate 3 to the transmitter 4. Received responses from the remote stations are fed from receiver 6 to an accumulator 8 which accumulates an address and passes it to store 10. Comparator 11 then compares the stored address with the next received address in accumulator 8, and provides a signal to a control logic depending on whether the two addresses are the same or not. If the two are the same, the control logic enables AND gate 12 to pass following data into buffer 13. If they are not the same AND gate 14 is enabled to feed the address from register 10 to a comparator 15 where it is compared with the contents of a store 16. If no match is found, the address is written into store 16, indicating that the first address in 16 will need to be repolled. When all transmissions have ceased, the control logic will enable AND gate 18 or 19 to pass the addresses from store 5 or 16 for transmission at the slower, repoll rate. If addresses were recognized, and hence stored in 16, AND gate 18 is enabled to repoll only the relevant stored addresses. If the message was garbled and no addresses could be identified AND gate 19 is opened to repoll all stored addresses at the slower rate.

[Also in Division H2] A regulating valve 80 connected in shunt with the E.H.T. supply (derived by rectification of the fly-back pulses across line transformer 50) to the ultor electrode 29 of a colour picture tube 20 operates to oppose both long term variations and variations at field frequency in the ultor potential, the latter variations arising e.g. from interaction between the line and field deflection circuitry in the operation of known " pincushion " correction circuits 43. Correction for the long term variations, which are caused by the beam current demand of tube 20 following variations in the D.C. component of the luminance signal and are manifest as corresponding variations in the " boost " voltage, is effected by supplying the D.C. component (from terminal LD) and the " boost " voltage (from terminal BB) to the control grid of valve 80 to vary its conductance in a compensatory manner whilst for compensation of the field frequency variations the conductance is further controlled by a voltage, termed the " boostedboost " voltage, in which such variations occur, this voltage, derived by rectification (diode 90) of line fly-back pulses to provide operating potentials for the screen-grid electrodes 25 (R, G, B), being supplied to the grid of valve 80 via a capacitor 97 which, together with a capacitor 95 and resistor 93 serves to attenuate variations at line and higher (e.g. video) frequencies.

As shown a standard bale fork is converted to an embodiment of the invention, four bale-receiving areas being formed by guide members 33 and guide rails 12. The device is advanced over the ground in the direction of arrow A towards a bale B lying on the ground as discharged by a baling machine. Right-hand static guide 13 and adjacent rotatable deflector plate 25 form a funnel-like bale-entry point. The bale B is retained in position B<SP>1</SP>, when a second bale can be collected into position B<SP>11</SP>. This latter bale B<SP>11</SP> holds a sensor 27 deflected against spring loading resulting in the associated plate 25 being rotated through a link 29 into the position shown dotted. The next bale-receiving bay is then provided by its two associated plates 25 with a funnel-like entry point and a total of eight bales can be accumulated in this way. In a modification upwardly pivoting gates at the bale entry points may be used, Fig. 12 (not shown). Entry into the bale-receiving areas may be facilitated by a single guide arrangement (replacing guides 13 and 25), which can be aligned successively with the bale entry points, Figs. 17, 18 (not shown). Attachments to convert bale loading devices which have no bale-accumulating function, but which are adapted to lift a pack of pre-assembled bales, into bale loading and loose bale accumulating machines with means to facilitate entry of bales into the machines via a plurality of bale entry points, are also described and such attachments may be provided as kits of parts.

In a fuse-switch having the casing lid interlocked with the operating handle, the operating is shaft mounted and is coupled to a spring-loaded link which drives an arm on a separate switch-operating shaft through a lostmotion connection. As shown, the handle 21, which may be moved through 180 degrees, is mounted on a shaft 1 supported in a casing 2 which is bolted to the cover 3. An arm 7 mounted on the shaft 1 carries a driving link 8 which is urged towards the cover 3 by a spring 9. Spaced abutments 11 and 12 on the driving link 8 which contact a driving roller 13 carried by arms 14 mounted on the switch-operating shaft 6, provide the lost-motion connection between the link 8 and the operating shaft 6. The shaft 6 actuates the moving contact assembly by the arrangement described in Specification 766,681. Opening of the switch in the " closed " position is prevented by a pin 41 on an arm 14 which engages with the face of the cover 3. The pin 41 may, however, be removable to allow inspection of the switch in the " closed " position with the cover open. Each fixed contact comprises a pair of inverted-T shaped fingers 27, Fig. 3, the adjacent ends of the cross-arms 28 of which are curved and engage one another to provide a rolling contact.
