Title: Improvements in or relating to straight-bar knitting machines
Inventor: CHALLENGER FREDERICK RAYMOND
IPC: D04B15/00
Filed: 1965-03-22
Abstract: In a method of knitting plain work onto a rib welt in a straight-bar machine the knocking-over bits are lowered with the needles when they are to be pressed.  This movement of the bits enables the needles to pull down the welt so that all the loops are below the tips of the needle beards.  The vertical movement of the bits is controlled by linkage having two cam followers one of which is moved from its cam so that the bits are controlled by the other when the bits are to be lowered.

Patent GB-657674-A (GB)
Title: Purification of streptomycin
Filed: 1947-05-07
Abstract: Streptomycin is purified by treating an acid aqueous solution thereof (pH about 1.5-5.0, preferably about 2.2) with activated charcoal (e.g. in an amount of about 2-5 per cent of the weight of the solution), filtering off the charcoal and adsorbed impurities, and recovering purified streptomycin from the filtrate.  The solution treated may be formed by acidifying a culture broth (e.g. by addition of a strong non-oxidizing acid, such as hydrochloric, sulphuric, phosphoric, formic, acetic or propionic acid), in which case the treatment is preferably followed by adjustment of the pH with alkali to above 6.5 (e.g. about 8-11, preferably about 9.5-10), adsorption of the streptomycin from the alkaline solution on to activated carbon, and elution with a dilute aqueous solution of a strong non-oxidizing acid (preferably after washing the adsorbate with water and then with a lower aliphatic alcohol).  Alternatively these operations may be reversed, the alkaline adsorption being applied to the culture broth adjusted to pH above 8 and the acid adsorption to the acid eluate from this step.  In either case the streptomycin may be isolated from the final solution by concentrating it to small volume (e.g. 0.1-0.3 per cent of its original volume, preferably by heating in vacuo to about 50 DEG  C. and preferably after neutralization to pH 6.0-6.6 by addition of alkali or especially by treatment with an ion exchange resin), and then precipitating purified streptomycin therefrom (e.g. by adding about 5 times the volume of methanol and 50 of acetone), separating the resulting precipitate by centrifuging, washing it with acetone and drying it. Where calcium or barium hydroxide has been used for making the solution alkaline prior to adsorption of the streptomycin on charcoal, this step is preferably followed by precipitation of excess metal ions by suspending the charcoal in water, adding sulphuric acid to pH 6.0 and filtering.  Examples illustrate various features of the invention, and its advantages over earlier processes. The Specification as open to inspection under Sect. 91 comprises also the use of the alkaline adsorption process alone, and the carrying out of the acid adsorption process at pH values up to 5.  An additional example of the combined process is given.  This subject-matter does not appear in the Specification as accepted.

Abstract: 1456749 Dehydrated potato granules AMERICAN POTATO CO 21 March 1974 [22 March 1973] 12571/74 Heading A2B Dehydrated potato granules are made by mixing at least partially mashed potatoes with a starch complexing emulsifier in an amount of 0.3-2.0% so as to coat the individual cells of the potatoes with emulsifier and granulating the mixture so produced by mixing with sufficient energy to break up agglomerates and expose new cell surfaces by injecting hot air onto the surfaces to dry the cells, whereby as the individual cells or minor agglomerates thereof become dry they are removed from the mixture by entrainment in the air and finally dried to a 7-8% moisture content. Specified emulsifiers are glyceryl monostearate, sodium stearyl fumarate, calcium stearoyl- 2-lactylate, sodium stearoyl-2-lactylate or a propylene glycol monoester. The temperature of the heated air is regulated such that the hottest air contacts the wettest mixture and vice-versa, and after entrainment in the air the larger agglomerates are returned to the mixture by expanding the flow area to reduce the airflow velocity above the mixture, thereby depositing the larger agglomerates back into the mixture. The emulsifier is preferably blended in at a temperature greater than the melting point of the emulsifier or as an aqueous colloidal dispersion of the same, optionally with 0.1- 1.0% by wt. of oil.

Abstract: 444,049. Television. RADIOAKT.-GES. D. S. LOEWE, 10, Wiesenweg, Steglitz, Berlin. April 27, 1936, No. 12616. Convention date, April 28, 1934. [Class 40 (iii)] A valve 7 is biassed to pass only the synchronizing signals, which are negative impulses of greater amplitude than the image signals, and the bias is varied in accordance with the average intensity of the signals to provide effective separation under varying conditions of reception or amplification. The received signal, rectified at 1, is fed over line 2 to the control grid of a cathode ray tube 4, and over a condenser 31 to the cathode of the valve 7. The grid current flowing in valve 7 produces a potential drop across the resistance-capacity combination 16, 15 to provide a variable bias, so that a variation in the strength of received signals or amplification produces a variation in the grid bias and therefore in the level at which the valve 7 becomes conducting. Alternatively, the unrectified carrier may supply the variable bias over a low-pass filter 21, 22. The variable bias may be applied over circuit 17, 18, 19 to the grids of the signal amplifiers. The manual amplification control of the signal amplifier may be ganged with the grid bias control of valve 7 to produce the same effect. The separated synchronizing signals are fed to phase reversing transformers 11, 12 tuned to the line and frame synchronizing impulses to control scanning oscillation generators. The curvature of the characteristic of the signal amplifier may be utilized to provide a greater amplification for the synchronizing impulses than for the image signals to facilitate separation.
