Abstract: 1,095,396. Modifying acoustics. ELOF HANSSON Inc. Feb. 19, 1965 [March 11, 1964], No. 7324/65. Heading G5X. An installation for masking undesirable sounds in a chamber, suitable, e.g. for making speech in an office unintelligible to people in an adjoining office, consists of a false ceiling 15 of a perforated acoustic material with a sound generator such as a loud-speaker positioned in the chamber thus formed between the true and false ceilings. The noise produced by the loudspeaker diffuses non-directionally into the room beneath and masks the sounds in the room. A noise-producing circuit is described in which the inherent noise of a transistor is amplified and fed through a frequency-controlling circuit to the loud-speaker (Fig. 3, not shown).

Abstract: 1,225,606. Hydrolysis of polyhalobenzenes. E. B. MICHAELS, and J. W. LEE. 28 July, 1969 [31 July 1968 (2)], No. 37721/69. Heading C2C. Halophenols and their corresponding alkali metal salts are prepared by hydrolysing a polyhalobenzene in a mixture containing ethylene glycol alkali metal hydroxide, an alkali metal derivative of ethylene glycol and an hydrolysiscontrolling agent which is either (a) one or more C 6-14  alkanes or (b) one or more di-lower alkyl C 1-7  benzenes. Specified agents include mineral spirits, deodorized kerosene, toluene, xylene, ethyl benzene and 1-ethyl-4-n-propyl benzene. The hydrolysis may occur between 170‹ to 200‹ C. After the hydrolysis the resultant mixture may be acidified to a pH between 11 and 13, a C 14-25  alkane added and the mixture then distilled to remove ethylene glycol. Alternatively, the hydrolysed mixture may be acidified to convert the phenate to the phenol and a small amount of ammonia or ammonium hydroxide added and the mixture distilled under vacuum. The preparation of polychloro- and polybromophenols and -phenates is exemplified.

A one piece shutter comprises blades and flexible portions and driving means which, when moved in a single direction, both opens and closes the blades by flexing the flexible portions. A two blade shutter Fig. 2 (and 1 not shown) and a three blade shutter Figs.4, 5 (not shown) are described. As shown, shutter 1 comprises two blades 3 and flexible portions 4, 5. When shutter release 13 is pressed, a spring 15 rotates a disc 11 in direction A until the disc abuts a stop 14. A lever 10 pivoted to the disc at 10a has a stepped end which engages a pin 7a joined to shutter 1 and slidable in a slot 16a. Protection of disc 11 reciprocates pin 7a through lever 10 to open and close the shutter. The shutter is re-tensioned by rotating disc 11 in direction C, a spring 9a engaging lever 10 during part of this rotation to prevent shutter opening. Shutter speed may be varied by altering the power of spring 15 by altering its length; or by slowing disc 11 with an arm 19; or by engaging a stop 11a on the disc by an electronically timed catch 18. The width of the exposure slot may be varied by altering surfaces 10c, d of lever 10.

Abstract: 1,227,594. Electrolytic capacitors. WESTEKN ELECTRIC CO. Inc. 24 May, 1968 [15 June, 1967], No. 24993/68. Heading H1M. The end of a solid electrolytic capacitor where a lead wire joins the capacitor body is sealed by depositing a bead of sealing material on the end and focusing radiant energy at the end to heat and soften the bead so that it flows over the end of the capacitor. As shown two parallel rows of capacitors are secured by soldering a lead to a bar 13. Two pairs of radiant energy sources 36, 41 and 37, 42 including infra-red lamps, and a pair of sealing material dispensers 28, 29 are adjustably mounted on a carriage 19 movable in either direction along guides 21, 22. A sensor (66) (Fig. 4, not shown) mounted on base 68 detects the presence of a capacitor when the lead interrupts a flow of air, and via a timer and solenoid valve (Fig. 5, not shown) causes a bead of sealing material to be dispensed at the end of a nozzle of each dispenser and wiped off by the passing capacitor. A switch 77 reverses the direction of movement of the carriage so that a second sealing operation is carried out, and causes air cylinder 76 to move the sensor to a position in which it again leads the nozzles of the dispensers.

Abstract: 1,234,016. Electromechanical delay lines. THOMSON-CSF. 11 March, 1970 [12 March, 1969], No. 11731/70. Heading H3U. A dispersive delay line using acoustic surface waves comprises a piezo-electric substrate 3 having input and output transducers 1, 2 in the form of thin-film electrodes 1A, 1B, 2A, 2B, the electrodes 2A, 2B comprising interleaved teeth. The spacing between the teeth increases along the length of the transducer 2 so that when a frequency-modulated pulse i is applied to the transducer a compressed pulse j is transmitted by the transducer 1. To reduce the amplitude of the side lobes s the teeth of at least one electrode, e.g. electrode 2B, are made of different lengths according to a desired function. The power radiated is proportional to the length of the teeth and hence the power radiated at each frequency corresponding to the different tooth spacings, will also vary. The function may be the gauss curve, Taylor's approximation to the Dolph-Tchebycher function or the Hamming function. In a modification both electrodes 2A, 2B have teeth of different length. In another modification, the electrode 1 also consists of electrodes having interleaved teeth and one or both of these electrodes have teeth of different length.
