Title: Improvements relating to penetrant flaw detection processes
Inventor: HISLOP JOHN DEREK
IPC: G01N21/91
Filed: 1966-01-20
Abstract: 1,101,552. Detecting surface flaws. ROLLSROYCE Ltd. and BRENT CHEMICAL PRODUCTS Ltd. Jan. 18, 1967 [Jan. 20, 1966], No. 2750/66. Heading G1S. In a process for removing from the surface of a body a liquid penetrant which has been applied thereto so as to penetrate into flaws therein, said process comprises applying to the said surface an aqueous or non-aqueous foam which includes a surface-active agent, and causing relative movement between the foam and the surface so as to remove penetrant from said surface while leaving it in said flaws. The penetrant may be based on a visible dye solution or a dye which fluoresces under ultraviolet light. The component is first dipped in the dye penetrant for about ten minutes and then exposed to a moving stream of foam. The foam utilized may be produced by passing air into an aqueous solution of a surface active agent and allowing the air to escape through a porous member such as a sintered metal, plastic or ceramic disc which is immersed in the solution. The flaws may be revealed by the application of a suitable developer material.

The flange 35 has a flat upper surface 37 which abuts and extends radially beyond the circumference of the closure 3, and as shown has a stop 43 on its upper face. In use, closure 3 is snapped over neck 23 of the bottle 5, interengaging annular beads 19, 21 on the closure and bottle respectively so that skirt 9 abuts flange 35. Tab 15 is then turned counterclockwise to stop 43, where tab 15 is not in register with notch 41 in flange 35 and the closure cannot be removed from the bottle. To remove closure 3, tab 15 must be rotated clockwise until it is in register with notch 41 so that the tab can be engaged from below. A flexible notched guard rug 45 may be loosely mounted about neck 23 and rotatable in either direction, so that a notch 47 therein may be brought into register with notch 41 and tab 15 for closure removal. Different plastics may be used for the closure and the bottle to minimize binding, or slip additives may be employed, and the closure may be impregnated with non-toxic unpleasant tasting substances to deter children from keeping it in their mouths.

Patent GB-762008-A (GB)
Title: Analysis of gases
Inventor: SKARSTROM CHARLES WILLIAM
IPC: G01N25/48
Filed: 1954-02-02
Abstract: <PICT:0762008/III/1> <PICT:0762008/III/2> The concentration of a key component gas in a mixture of gases is continuously measured by passing the test gas mixture and a reference gas mixture alternatively, and preferably periodically, past a thermal transducer.  The reference gas mixture differs from the test gas mixture only in the amount of key component gas, and both mixtures are brought to the same temperature and pressure, whereby, owing to the heating effect of adsorption at the transducer surface of the key component gas, the transducer develops a fluctuating D.C. electric signal which is a function of the key component concentration differential between the two gas mixtures.  The transducer output signal may be increased by locating on or near the transducer, material selectively adsorbent with respect to the key component gas. The transducer may be a resistance thermometer or thermopile and may be used for measuring the concentration of water vapour in gases such as nitrogen, air, carbon-dioxide, propane, and ethane; the concentration of butane, isobutane or propylene in a carrier gas such as propane, and the concentration of benzene in a carrier such as air.  Glass-wool, adsorbent cotton, soft paper tissues, silica gel, or activated alumina may be used for the adsorbent when water vapour is the key component gas.  As shown in Fig. 1, for measuring the concentration of water vapour in air, a portion of a moist air stream at 10 is lead directly by tube 13, a valve 22, and heat-exchanger 3 to a cell 7 containing a bed 4 of silica-gel and a thermopile 16. Another portion of the moist air stream at 10 is dried at 1 or 2 to remove substantially all water vapour and passed over tube 15, valve 22 and the heat-exchanger 3 to a cell 6 similar to cell 7. Periodically, either manually or through a time controlled switch 20, the four way valve 22 is moved to switch the moist and dry streams from one cell to the other.  The thermopiles in the two cells are arranged so that the signals generated in each are additive and serve to operate a meter or recorder 9 which may be calibrated to read directly the water concentration.  The periodic time of the switch 20 may vary from 0.1 to 10 minutes.  A two minute period is preferably used and depends on the time for the transient signal produced at each switch over of the air streams to reach its maximum.  A further valve 11 allows driers 1, 2 to be used alternatively while the other is being regenerated, and the heat-exchanger 3 brings both air streams to the same temperature before passing them to the cells 6. 7.  In another embodiment, Fig. 3, a portion of the test gas stream at 60 is dried at 61; the dry and moist stream at 62, 33 are metered at 63, 64 and passed by a valve 30 alternatively through the heat-exchanger 35 to a single cell 37.  The fluctuating output of the thermocouple 40 is amplified at 43, rectified at 45, e.g. by a commutator driven synchronously with the valve 30 by a synchronous motor 50, filtered at 46 and fed to a D.C. recorder.

Abstract: 600,261. Pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. Feb. 7, 1945, No. 3162. Convention date, Oct. 4, 1943. [Class 40 (v)] In a modulated pulse communication system, calling and other signalling is effected by the production of a signal interval during which the pulses are suppressed or displaced by a constant amount corresponding to a D.C. modulation, or modulated by a special low-frequency signal source. In one embodiment, Fig. 1 (not shown), applied to a pulse multiplex system, signalling keys are arranged to disconnect the outputs of the channel transmitters. At the individual channel receivers a valve responsive to the cessation of its pulse input operates a buzzer, through a relay, during the signalling intervals. In a second multiplex system, each channel is provided with a key 36, Fig. 3, which connects a D.C. source 35 to the channel modulator and the corresponding receiver demodulator 16 is arranged to produce a corresponding D.C. output which energizes relay 32 and buzzer 34 through valve 31 which is irresponsive to normal modulation fed to the channel output through condenser 24. The D.C. source may be replaced by a low-frequency signalling source and a low-pass filter provided at the receiver to select the signal output. Specifications 509,820, 521,139 and 600,259 are referred to.
