Title: Improvements in direction finders incorporating electron devices
Filed: 1929-07-12
Abstract: 334,995. Perryman Electric Co., Inc. Dec. 5, 1928, [Convention date]. Vacuum tubes.-A discharge device for use as a compass, for example in aircraft, consists of a cathode, an anode and a magnet fixed relatively to the electrodes and sensitive to the earth's field so as to control the discharge in accordance with the position of the magnet in the earth's field. As shown, a tubular magnet 1 of material of high permeability such as permalloy, a cathode 5, and anodes 8 are mounted inside an evacuated or gas-filled tube 10. A tubular cathode may be of magnetic material such as nickel so as to act as a shield for the magnetic field produced by the heating current through an internal filament; or a filament cathode may be used. A potential may be applied to the magnet. A galvanometer is included in the circuit of the discharge. In a modification, the magnet is flat and a winding is mounted on a pole. In other arrangements the magnet, is arranged outside the tube and the path of the discharge may be in alignment with the poles.

Abstract: 577,063. Supplying liquids to grinders &c. AVIMO, Ltd., STEVENS, H. C. M., and PAUL, A: M. W. Nov. 3, 1944, No. 21569. [Class 60] [Also in Group XXII] Means for supplying liquids to grinding- machines and the like comprises a pair of closed tanks to contain liquid and compressed air, flow and return pipes connecting with each tank, valves for controlling said pipes so that whilst liquid is being discharged from one tank it is being returned to the other, and a valve for conveying compressed air to either tank. As applied to a lens grinding-machine on a bench a with rotary, laps b and troughs c, closed tanks g, g are provided with flow pipes h connected, through a control valve i and a pipe k, to a distributing pipe m; return pipes n connected through a valve o and a draining pipe p, to troughs c ; and with pipes q for the compressed air from a general supply pipe and through a valve (not shown). The said valves are such that either tank can be put into connection with the pipes above the particular valve. Compressed air forces the liquid, which carries abrasive particles, from the full tank to the machines and then drains back into the empty tank, this action being reversed when the first tank is emptied. Rotary stirring paddles (not shown) are provided in each tank.

Title: Improvements in methods of preparing concentrates of natural vitamins
IPC: A23L33/15
Filed: 1938-07-26
Abstract: 517,401. Vitamins. DRUMMOND, J. C. July 26, 1938, No. 22255. [Class 2 (iii)] Concentrated extracts of fat-soluble vitamins, i.e. vitamins of the A, D and E groups and vitamin K, are prepared by treating solutions of the vitamin-containing material with finely divided materials which show a preferential adsorption of the vitamin. The vitamin can then be eluted from the adsorbate with suitable solvents. In the example, a solution of wheat germ oil in petrol or trichlorethylene is allowed to percolate through a column of aluminium oxide which is subsequently eluted with a mixture of methyl alcohol and ether to give a solution containing a large proportion of the original vitamin E. Other eluting liquids such as ethyl alcohol, diosian or acetone or mixtures of these can be used.

Abstract: 1395049 Document with bar code; reader and printer S B ELECTRONIC SYSTEMS Ltd 11 May 1973 [12 May 1972 26 May 1972] 22270/72 and 24917/72 Headings G4M and G4H A document such as a label carries bar codes of two contrasting characteristics, i.e. magnetic recorded level or reflection characteristics and of two possible widths. The bars are arranged in pairs ab, Ab, AB or aB with the capital letter denoting a wide bar and the lower case letter a bar 1/3 the width of a wide bar. A reader R has a sensor the width of a wide bar. The pairs are arranged so that ab = 1, AB = 010, Ab = 00, and aB = 01 and 10 alternately, or the inverse of the digits. The coding is for even parity numbers (as described 8-bit numbers with four "1"s), and allows even packing density with eight-bits occupying the space of sixteen narrow bars. A decoder (Fig. 3), contains a shift register J through which a "1" is passed to successively enable gates E, F, G and to provide a signal 010 on line K. 1's are applied to the appropriate gates E, F, G when the values A, a, B are read so that the possible values of L are 010, 111, 101, 110 or 011. These are used to enable the K signals where a "1" exists in L so that ab=1 AB = 010, Ab = 00 and aB = 01 or 10 depending on the state of bi-stable CK. A circuit (Fig. 4), controls the printing of data. The data can be formed by printing one or three narrow bars (Fig. 2, not shown), and leaving one or three spaces. The circuit works according to the table Initially bi-stable A is set and depending on the value of the second bit of the value to be coded Q2 the output 2 is varied and a different bi-stable is set. For the coding used each bit corresponds to two narrow bars or marks, two bits correspond to four narrow spaces or marks and three bits to six narrow spaces or marks. Thus for each bit both 1 and 2 outputs are supplied from switch N. Using the table the value 11001010 in the left hand half of Fig. 1 (ababAbabAB) produces a signal which if the l's produce bars corresponds to the bar code shown in the figure.

Abstract: The sulphonation of oils and fats or their corresponding free acids is effected in the presence of esters of polyhydric alcohols with fatty acids having fewer carbon atoms than the oil &c. being sulphonated and in every case having not more than twelve carbon p atoms in the molecule.  The products are wetting agents which are resistant to acids.  In an example, castor oil is dissolved in triacetin and sulphonated with oleum.  Glycerine and glycol mono acetic acid esters, and coconut oil fatty acid a -glyceride, obtained by removing the fatty acid constituents containing more than twelve carbon atoms from raw coconut oil or palm kernel nut oil and heating with glycerine, are referred to.  The Specification as open to inspection under Sect. 91 also comprises the use of aromatic and hydroaromatic esters of lower fatty acids during the sulphonation; acetic acid phenyl ester, propionic acid cyclohexyl ester and coconut oil cresyl ester being mentioned.  In an example, stearic acid is treated with chlorsulphonic acid in the presence of acetic acid b -naphthyl ester.  This subject-matter does not appear in the Specification as accepted.
