Title: Dispersing gases into liquids
Inventor: RONCA EDWARD
IPC: B01F3/04
Filed: 1951-08-09
Abstract: Gas is delivered in a dispersed state into a liquid through a porous element which is made of material normaly wettable by the liquid, but which has been subjected to treatment so as to coat the surface of the material in the pores with a substance, e.g. a silicone or wax, which renders the surface non-wettable by the liquid.  The porous element may be, for example, ceramic, porous carbon, sintered glass or sintered metal.  The Specification refers to applications wherein gas is introduced in a dispersed state into liquids to effect agitation or to promote chemical reactions; and also to aeration of liquor in which organisms such as bacteria or yeast cells are growing.ALSO:Gas is delivered in a dispersed state into a liquid through a porous element which is made of material normally wettable by the liquid, but which has been subjected to treatment so as to coat the surface of the material in the pores with a substance, e.g. a silicone or wax, which renders the surface non-wettable by the liquid.

Title: An improved knitted fabric and method of producing the same
IPC: D04B1/00
Filed: 1933-07-04
Abstract: 423,502. Knitted fabrics. BLACKBURN & SONS, Ltd., G., Atlas Works, Kirkewhite Street, and BLACKBURN, G. S., Sundridge, Cyprus Road, both in Nottingham. July 4, 1933, No. 18906. [Class 74 (ii)] An anti-ladder fabric comprises a six-course repeat in which first and fourth courses are composed of single threads knitted on every needle, second and third courses are of twin threads, one being knitted on every alternate needles, and both on the remaining needle, and fifth and sixth courses are also of twin threads, the action of the needles being the reverse of that in courses two and three. At the first and fourth feeders, single threads 1 and 4 are supplied and knitted in the usual manner. At the second and third feeders, the short butts of needles A are caused, by a cam F, to rise into an upper passage C. Thus, needles A take yarn 2 or yarn 3 which is missed by needles B, whose long butts are directed by a cam E into a lower track D. Both needles subsequently take and knit yarn 2a or yarn 3a. At the fifth and sixth feeders, a somewhat similar group of cams, Fig. 4, (not shown), elevate the long butted needles B to take a yarn 5 or a yarn 6, which is missed by the short butted needles A. Both sets subsequently take and knit yarn 5a or yarn 6a. The needles may be independently controlled by pattern mechanism and thus the minimum number of three feeders employed.

A cigarette filter tip or other filter comprises a tubular sheath, which may be of longitudinally butt-jointed thick paper 31, Fig. 10, surrounded by longitudinally lap-jointed thin paper 11, and a core of creped paper or cellulose wadding 14 with its normal corrugations extending approximately perpendicular to the sheath axis and secondary corrugations extending transversely thereof. One or more layers of paper or wadding 14 may be used, bunched as shown or spirally wound, and interleaved if desired with a layer or layers of cotton wool, wool, silk, cotton, asbestos, cellulose acetate or viscose. The secondary corrugations may be produced by notches in the edge of the blade 25, Fig. 3, used to form the normal corrugations by scraping partially dried paper pulp 22 from a rotating roller 24, the pulp passing on to a conveyer 26 whereon it is sub-divided by knives 27. Alternatively, the scraped-off band of pulp may be corrugated by passing it between knurled rollers. Filter tips according to the invention may be made on a machine analagous to a continuousrod cigarette-making machine, a web, if necessary preformed to shape, of one or more strips of core material taking the place of the tobacco filler and means being incorporated to feed two superposed wrappers to the garniture if it is desired to form the sheath as in Fig. 10.

Oil is supplied to the stylus from a reservoir 28 mounted on the device 15, the oil being conducted through a capillary tube 29 which may contain a. wick. In addition, the blank itself may be lubricated, by rubbing the surface with oil or wax. A system for either enabling a record to be made or sound to be reproduced therefrom at will, using the same electromagnetic vibrator and the same amplifying valve, is shown in Fig. 3. The recording microphone 31 can be connected through a transformer 33 and switch 35 to the input terminals of a valve 37, the output side of which can be connected through a switch 39 to the device 15. This may be provided with a diamond or other suitable recording stylus. When a record has been made, reproduction can be effected by substituting for the diamond a. fibre needle, and reversing the switches 35, 39. The device 15, which is to function as a transmitter, is then connected to the input side of the valve, and the output is connected to a loud-speaker 42.
