Abstract: 1,128,578. Recovering condensables and regenerating adsorber beds. CONTINENTAL OIL CO. 30 Aug., 1967 [1 Dec., 1966], No. 39576/67. Heading B1L. [Also in Division C5] Condensables, especially hydrocarbons, which are sorbed on a sorbent are desorbed to obtain two or more separate fractions of the condensables by treating the sorbent bed in two or more separate portions with separate heated gas streams. Thus, gas heated in 21 is introduced by lines 8 and 5 into bed 1 containing silica gel or activated carbon saturated with hydrocarbon condensables. The desorbed effluent streams leave respectively by lines 4 and 10, and pass by lines 9 and 24 to condensers 12 and 25, and thence to separators 14 and 26, uncondensed gas returning by lines 15, 17, 18 and 20 to heater 71 for recycling. If required, valve V5 is closed and V13 opened so that the two effluent streams are combined before being condensed. Alternatively, V10 may be closed and V9 opened so that effluent vapour from separator 14 is combined with the effluent in line 10 before it is condensed. If the flow of feed hydrocarbons with which the bed is aturated was downward by lines 2 and 4 and then through the bed, heavier hydrocarbons will be obtained in separator 14 and lighter hydrocarbons in separator 26.

Abstract: 1477313 Respiratory valves J PFITZNER 12 Aug 1974 [22 Aug 1973] 39864/73 Heading AST [Also in Division F2] A valve for directing flow of respiratory gas to and from a patient comprises a first port 3 adapted to be connected to a source of respiratory gas, a second port 2 adapted to be connected to a patient, a third port 4 adapted to convey exhaled respiratory gas from the valve, first obturating means for controlling flow between ports 2 and 3, a passage in continuous communication with port 2 through the first obturating means, and second obturating means for controlling flow through the passage and arranged to prevent flow through the passage when the first obturating means allows flow between ports 2 and 3. The first obturating means may comprise a diaphragm 20 having apertures in its central portion to produce a continuous passage from port 2 to passage 14. Exhalation by the patient causes diaphragm 20 to be pressed upwards against knife edges and thus to close off the inspiration port 3. The second obturating means in the form of a diaphragm 18 then lifts from rims 29, 30, 31 to allow exhaled gas to pass through passageway 16 to an exhalation port 4. On inhalation diaphragm 18 closes passageway 16, and diaphragm 20 lowers to allow respiratory gas to pass to port 2. Channel 27 connected to port 3 assists in the closing of passageway 16 by diaphragm 18. A safety feature of the device is that should port 3 be blocked then inhalation may be achieved via port 4, passageway 16 and passage 14.

Abstract: 1,056,437. Colour television receivers. SONY CORPORATION. Oct. 11, 1963 [Oct. 13, 1962], No. 40214/63. Heading H4F. The invention relates to a colour television receiver, Fig. 5, which utilizes a chromatron cathode-ray tube 6, a received N.T.S.C. signal comprising a luminance component Y and a chrominance sub-carrier component Cs being applied to the tube gun 5 to modulate the beam intensity whilst a sinusoidal potential S at the sub-carrier frequency is applied between the switching grids 4a, 4b. Operation proceeds as shown in Fig. 4 with the beam deflected cyclically over the red, green and blue phosphor strips 3R, 3G and 3B so as to reproduce the colours at the places marked by a O in phase with their representation by the chrominance signal Cs. With the object of improving the accuracy of colour reproduction a further signal P at three times the sub-carrier frequency is also applied to the tube gun so as to reduce the beam intensity at the places marked by an X. In accordance with the invention the amplitude of signal P is modulated in accordance with the amplitude of the sub-carrier signal except at low amplitudes. In carrying out the invention the signal P, which is derived by means of a frequency multiplier 14 from a signal of subcarrier frequency obtained from an oscillator 12 synchronized by the sub-carrier " bursts," is applied to the tube gun 5 via an amplitude modulator 15 which is controlled by the output of a detector circuit 16 responsive to the chrominance signal Cs. Furthermore the detector incorporates a bias source 20 which prevents the detector producing an output from lowamplitude (i.e. low saturation) sub-carrier signals. In practice stages 14 and 15 are combined into a single stage comprising a non-linear amplifier with a resonant anode circuit tuned to three times sub-carrier frequency. Fig. 7 shows one arrangement based on the use of a triode 26. A second circuit, Fig. 8 (not shown), uses a pentode.
