Abstract: 1,187,164. Non-alcoholic beverages. NATIONAL RESEARCH DEVELOPMENT CORP. March 20, 1969 [March 26, 1968], No.14556/68. Heading C6E. An ethanolic beverage e.g. sherry or cider, is distilled under reduced pressure to remove ethanol therefrom, the flavour constituents are extracted from the ethanolic distillate with a low boiling point solvent in which ethanol is substantially insoluble (isopentane, ethyl chloride or liquid carbon dioxide under pressure), the solvent extract is separated from the distillate, and the flavour constituents are recovered from the solvent extract by removal of the solvent and replaced in the residue from the original distillation. The whole is brought back to its original volume with water. The ethanol-free beverage may be supplemented by the addition of further volatile flavour constituents. Thus, according to the examples, excess of n-propanol, iso-butanol and n-butanol was added to ethanol-free sherry residue whereas the amount of amyl and hexyl alcohols returned was reduced. With cider small amounts of npropanol and glycerol were additionally included with the flavour constituents returned, and the ethanol content of the flavour-replenished residue was brought up to the legal limit of 2% proof spirit. The product was carbonated.

Abstract: 640,015. Band-width compression. BRITISH TELECOMMUNICATIONS RESEARCH, Ltd. and BELL, D. A. June 5, 1947, No. 14934. [Class 40 (iv)] [Also in Group XL (b)] In an arrangement for compressing or expanding the frequency range of a signal the wave form of the signal moving along the delay line 3 at one speed is scanned by a succession of pulses moving along a second delay line 4 at a different speed. As shown in Fig. 1 each delay line is divided into sections of equal time delay, different for the two lines, the output from the sections of the line 3 being fed to the output circuit 8 via a succession of gates 7 which are opened in turn as the pulse in travelling along the line 4 reaches the end of each section thereof. To avoid undesirable change-over effects at the ends of the delay lines, attenuations may be inserted between the gates 7 and the output circuit 8, the loss introduced being greatest at the ends of the line. In a modification, Fig. 3, the delay lines are continuously loaded and in contact along the whole of their lengths with a block 26 of material having a non-linear voltage/current characteristic, the output being collected from spaced conductors 27, 28 therein. The cross-section of the block is reduced at its ends in order to produce the required attenuation of the output at these points.

Abstract: 1,083,086. Focus and aperture setting. PRONTOR-WERK ALFRED GAUTHIER G. m. b. H. April 9, 1965 (April 18, 1964], No.15096/65. Heading G2A. As shown, the focusing ring 21 of a camera has a mark 23' moving across a fixed focusing or distance scale 22. A conversion scale 27 converts this non-linear scale into a linear one. The aperture is set by a ring 30, which has three working ranges, a "flash" range 31, a time exposure range 32, and a daylight range 33, the selected range being indicated by a fixed mark 34. In the range 32, a scale of aperture values is shown at 35. Coaxial with the other rings is a guide number setting ring 36, having a mark 46 which is set to the selected guide number on a scale 37 carried on a further ring 45 (when flash operation is required). Rings 45 and 36 can be locked together by a detachable coupling member 44 which latches into one of a number of depressions 43 on ring 36 according to the number on scale 37 to which mark 46 is set. Rings 45 and 36 now turn as a single unit, but are brought into action only when the aperturesetting ring is operating on the "flash" range 31. This is effected by lugs 38, 39, on rings 30 and 36 respectively. Lug 39, and hence ring 36, is urged to the right by a spring 40, until it reaches a stop 42. Ring 32 is operating, in the position of Fig. 2, on the range 31, and ring 36 is unaffected, since lugs 38, 39 are out of contact. As ring 36 moves to the left, at the moment that mark 34 indicates the transition point from range 32 to range 31, lug 38 comes into contact with lug 39. Further movement of ring 30, now operating on the "flash" range, carries ring 36 with it. The movement is continued until a follow-up mark 47 on ring 45 is brought to the same region of the conversion scale 27 as is indicated by the focus-setting mark 23'.
