Title: Improvements in films, sheets and the like and processes for their manufacture
IPC: C08L1/12
Filed: 1932-08-06
Abstract: Films, foils, or sheets are obtained by extruding a solution of a cellulose ester or ether in a neutral solvent, solvent mixture, or mixture of solvents, into a coagulating medium containing the same solvent, solvent mixture, or mixture of solvents, and subjecting the coagulated materials to a drying operation, the solvent, or in the case of a mixture of solvents at least one constituent thereof, being less volatile than the non-solvent so that during drying the materials retain some solvent after all the non-solvent has been removed. Alternatively, the concentration of the cellulose derivative does not exceed 15 per cent, and the solvent, or in the case of a mixture at least one constituent thereof, has a boiling point not less than that of the non-solvent of the coagulating medium or is not more volatile than the non-solvent, and removal of the coagulating medium is effected by washing or drying.  The cellulose derivative may be cellulose acetate or other organic ester or ether of cellulose.  The solvent may be dioxane methylene ethylene dioxide, an ester or ether of dioxane dicarbinol, diacetone alcohol, ethyl lactate, diethyl tartrate, or an ester of glycol or methyl glycol. The non-solvent may be water, alcohol, or a hydrocarbon.  Salts or sugars may be added to the coagulating bath.  The films may be stretched continuously with production. In an example, cellulose acetate dissolved in diacetone alcohol is extruded on to a drum immersed in ethyl alcohol containing 10 per cent of diacetone alcohol.  The film obtained is dried on a steam heated cylinder and yields a transparent product.  In another example, a 15 per cent solution of cellulose acetate in dioxane is extruded on to a drum immersed in an aqueous solution of dioxane. The film is dried on a heated roller and yields an opaque product. Specifications 177,868, 179,234, [both in Class 2 (ii), Cellulose &c.], 340,324, 340,325, 340,326, 340,436, 340,437, 343,062, 375,423, 378,858, 380,819, 400,589, and 401,679 are referred to.

Patent GB-1109443-A (GB)
Title: Echo-sounding apparatus for examining strata below the sea-bed
Inventor: OVENS STANLEY FREDERICK
IPC: G01V1/24
Filed: 1964-05-29
Abstract: 1,109,443. Geophysical exploration. SMITHS INDUSTRIES Ltd. 25 May, 1965 [29 May, 1964], No. 22377/64. Heading H4D. In an ultrasonic pulse-echo sounding system for examining strata below the sea-bed, a control circuit responsive to the sea-bed echo generates a control waveform for varying the gain of an amplifier connected between the receiving transducer and a chart recorder in such a manner that the gain has a low value when the sea-bed echo is received and subsequently rises progressively to a higher value, thereby suppressing the sea-bed echo reverberation in the recording and compensating for the rapid attenuation of acoustic energy in the strata. In the embodiment of Fig. 1 (Provisional) the sea-bed echo is selected by a fixedgain amplifier 15 and triggers a generator 16 to produce the control waveform for varying the gain of the receiving amplifier 13. A suppression pulse is also applied to generator 16 from a transmission pulse generator 10 to prevent generator 16 responding to the signal produced by direct passage of the transmitted pulse to the receiving transducer. The control waveform produces a sharp drop in gain upon receipt of the sea-bed echo, followed by a progressive recovery to the level determined by a sensitivity control signal which is also applied (not shown) to amplifier 13. The sensitivity control signal may provide conventional swept gain to compensate for the decreasing strength of echo signals with distance. In the embodiment of Fig. 2 (not shown), generator 16 is replaced by a waveform generator (17) and a suppression gating circuit (18) whose outputs are such that the gain of amplifier 13 is normally held at a low value, rises progressively during a gated recording interval commencing with the arrival of the sea-bed echo, then returns to the low value. To suppress the sea-bed re-echo, a generator (22) produces a suppression waveform for amplifier 13 after a delay (measured from the instant of transmission of an acoustic pulse) which is selected by circuits (19) and (20) according to the interval between the transmission of the acoustic pulse and the reception of the first sea-bed echo. An additional, adjustable, delay is provided to take into account the fact that the transmitting and receiving transducers (or combined transmitting-receiving transducer) are (or is) below the surface of the water and the sea-bed re-echo time is therefore not exactly twice the sea-bed first-echo time. The amplitude and rate of decay of the sea-bed re-echo suppression waveform are adjustable. In either embodiment, the rate and magnitude of the variation of the gain of amplifier 13 are adjustable, and a delay device may be connected between the receiving transducer and the gain control circuits to introduce a delay such that one sea-bed first-echo signal generates the control waveform for the passage of the next sea-bed first-echo signal through receiver amplifier 13.

Abstract: 439,313. Feeding webs. AMERICAN MACHINE & FOUNDRY CO., 511, 5th Avenue, New York, U.S.A. Aug. 3, 1934, No. 22642. Convention date, March 15. [Class 100 (i)] [See also Group VIII] In mechanism for use in wrapping-machines wherein a wrapping web or band and a label &c. band are united by passing one band over a heating unit to render it adhesive and then bringing it into contact with the other band, the heating unit and band to be heated are automatically separated when the feeding movement of the band is interrupted. The adhesive band may consist of waxed paper or coated regenerated cellulose, and may comprise several narrow bands. As shown, a narrow label band B from a reel BR passes around a rod 20, contacts with a heating unit 17 between guide rods 26 and 27 which form part of a frame 28 pivoted at 25 to arms 19, and adheres to and is drawn into the wrapping-machine with a web of wrapping material from a roll WR. The frame 28 is weighted at 29, so that when the feed of the wrapping material is interrupted, the tension in the band B falls off and allows the frame 28 to rock on its pivot 25 and remove the band B from the heating unit 17. The rod 20 is provided with an arm 23 carrying a latch adapted to engage either of holes 22a and 22b in a quadrant 22c, enabling the heating unit and frame to be swung into or out of operation.

Patent GB-473923-A (GB)
Title: Improvements in or relating to preparation of sterol derivatives
IPC: C07J75/00
Filed: 1936-08-18
Abstract: Chloro- and bromo-cholestanes are prepared by reacting a cholestanol with thionyl chloride or bromide.  This effects the replacement of the hydroxyl group by chlorine or bromine and at the same time induces a Walden inversion so that the halogen compound is of the opposite stereo-chemical-configuration to the parent hydroxy compound.  The occurrence of the Walden inversion enables the process of the invention to be used as a step in the preparation of cis-androsterone from the naturally occurring b -cholestanol.  In examples: (1) a mixture of b -cholestanol and thionyl chloride is allowed to stand overnight, then diluted with water and extracted with ether.  The product so obtained consists of epi-chloro-cholestane; (2) epi-cholestanol and thionyl chloride are mixed and the product worked up as in example (1) to give b -chloro-cholestane.  A convenient means of obtaining the epicholestanol for use in example (2) is to oxidize beta-cholestanol to beta-cholestenone, and then reduce this substance in dibutyl ether solution by hydrogen using a reduced platinum oxide catalyst in the presence of a small amount of hydrobromic acid.  The Specification as open to inspection under Sect. 91 includes also an example of the preparation of 3-chloro-cis-androsterone from 3-epi - chloro - cholestane by oxidation with chromium trioxide in glacial acetic acid solution, and also the hydrolysis of a 3-halogeno-cis-androsterone to cis-androsterone.  This subject-matter does not appear in the Specification as accepted.
