Patent GB-431313-A (GB)
Title: A process for concentrating organic carboxylic acids
Filed: 1934-11-21
Abstract: Organic carboxylic acids such as formic, acetic, propionic, butyric and lactic acids are concentrated by means of mixed aliphatic ethers which may contain primary, secondary or tertiary alkyl groups, a large number of such ethers being mentioned.  The ethers may be used as extracting agents or may be distilled with the aqueous acids so as to carry off the water as azeotropic mixtures.  Usually it is preferred to use an ether of lower boiling-point than the acid to be concentrated.  The acid may be extracted in counter-current in a tower, and the ether may be injected under pressure through a small orifice, or the dispersion may be effected by other means; or the acid may be dispersed in the solvent.  The ethers may be employed in admixture with other solvents such as hydrocarbons (pentane, hexane, light naphthas and the like) and/or esters.  If the organic acid to be concentrated contains mineral acid, this should be removed for instance by treatment with barium oxide, carbonate or acetate in the case of sulphuric acid or, silver acetate in the case of hydrochloric acid.ALSO:Organic carboxylic acids are concentrated by means of mixed aliphatic ethers which may contain primary, secondary, or tertiary alkyl groups, a large number of such ethers being mentioned.

Abstract: 1,186,354. Stud and socket fastenings. J. S. C. EKINS. 5 Sept., 1967 [26 July, 1966], No. 33542/66. Heading E2B. Knock-down jointing means comprises a first member containing a keyhole shape aperture extending through the member between opposed faces thereof, said aperture having a first wider portion 4 and a second narrower portion 6 extending longitudinally from one end of the wider portion, the side walls of the second portion 6 being divergent between the opposed faces of the member to give said portion a tapering cross section and a second member 10 having divergent walls 14 complementary to at least one region of the divergent walls of the aperture second portion, said second member being locatable within the wider portions of the first member aperture and slidable therefrom into the second portion to engage together the two members at the regions of their divergent walls to make the joint. In the construction shown the two portions of the key hole-shaped aperture are of substantially rectangular shape and the second member is in the form of a flat sided wedge. The divergent walls of both the aperture second portion and the second member 10 are provided with ribs 16 which when the second member is in the aperture second portion engage each other to lock the second member in the aperture second portion. Each member is provided with a plurality of countersunk screw holes for connecting the members to the components which are to be fastened together. As shown the two members are made as a single moulding, the member 10 being contained in the moulding in the aperture first portion, the two members being connected together by gates 12 that can be easily broken; the moulding as shown has two key hole apertures each of which contains a second member 10. In an alternative construction the second member 10 instead of being a flat sided wedge is a frustrum of a cone with a single countersunk screw hole through it and the aperture through the first member is suitably modified. The members are again made as a single moulding but in this case the moulding has four key hole shaped apertures and four second members, the second members being connected to the side of the first member by gates which are easily broken.

Title: Improvements in methods of connecting branch pipes to quartz tubes and similar quartz bodies of comparatively great dimensions
IPC: C03B19/09
Filed: 1931-12-04
Abstract: 377,071. Making quartz tubes. JENAER GLASWERK SCHOTT & GEN., Otto-Schott-Strasse, Jena, Germany. Dec. 4, 1931, No. 33611. Convention date, Dec. 9, 1930. [Class 56.] A method of connecting a branch pipe to a quartz tube or similar body of comparatively large dimensions consists in inserting the pipe into a container containing quartz sand, melting the sand to produce a fused mass with which the end of the pipe combines, and then expanding the fused mass in a mould to form a tube of the desired size. The container a, Fig. 1, which also serves as a mould, is provided with a side-piece a<1> to hold the branch pipe c in position, and with a carbon electrode d. The container is filled with sand b which is melted around the electrode and forms a fused mass to which the inner end of the pipe e is welded. After the electrode and the excess sand have been removed from the container, one end of the plastic mass is pressed together to seal it, and the mass is blown by compressed air through the open end until it fills the container, as shown in Fig. 3. After the body thus formed has cooled, the superfluous portions g are removed.

Patent GB-339114-A (GB)
Abstract: 339,114. Newton, W. A., Bowser, J. W., and Lum, F. Dec. 5, 1928. Contacts, arrangement of external.-In an electric switch operated by oil pressure to control the ignition circuit, a cam-lover is pivoted to the piston rod moved by oil pressure, to close the circuit for starting, which lever, on the development of oil pressure, falls and allows the switch to function automatically. A piston b on a rod d slides in a bore a' of a casing a which is connected at c to the lubricating system of a motor vehicle. The rod d passes through an insulating block h on which are mounted resilient contact members i<1>, j<1> connected respectively to terminals i, j which are connected in the coil ignition circuit. When the oil pressure falls a spring s moves the rod d to the right and separates the contacts i<1>, j<1>. A member k is screwed on to the end of the rod h and has pivoted to it a thumb-piece m. For starting the engine the member m is turned into a horizontal position where it keeps the contacts together. When the oil pressure becomes normal the piston b moves further up to the block l and allows the member m to rotate under its own weight and the switch may then function automatically. For magneto ignition, the contacts are adapted to be closed on a fall of oil pressure. The device is shown mounted on a dash board r by means of nuts p, p<1>

Abstract: 846,004. Electromagnets. LANDIS & GYR A.G. Nov. 8, 1956 [Nov. 9, 1955], No. 34197/56. Class 35. In a relay-operating electromagnet which includes a stator having a substantially closed iron shield 2 magnetically screening the electromagnet and an armature 12, 13 capable of limited rotary motion, there being passive and at least one active air gap between the armature and stator, the passive air gap is of uniform width and is formed between a conical portion 12 of the armature and a conical bore 11 in the core 8 of a coil 10 surrounding the conical portion 12. The active air gaps are formed between bent-over poles 5, 6 and 14, 15 of a stator pole plate 3 and an armature plate 13 respectively screwed to the end 1 of the shield 2 and riveted to the armature cone 12. The armature rotates on a pivot 20 and a spindle 22 which transmits the output movement, respectively borne by a thrust bearing 21 and an end bearing 23. The armature rest position is determined by a biasing spiral spring 18 and a stop 25 extending from one of the coil bobbin flanges, and when the coil 10 is energized armature rotation is limited by a similar stop 26. The armature is biased towards the left-hand end of Fig. 1, when inoperative by the spring 18 and when operative by the magnetic attraction being greater in the active than in the passive air gap. Armature concentricity is achieved by pulling it to the right to engage its conical part 16 with an end of the core 8, and then tightening pole plate securing screws 4 passing through enlarged holes in the shield end 1.
