Filed: 1935-06-05
Abstract: 439,934. Two-part couplings. FARISH, R. E., Columbus, Georgia, U.S.A. June 5, 1935, No. 16405. [Class 38 (i)] A two-part coupling comprises a plug and a socket each having axial and ring contacts, the ring contact of the socket being sunk in a narrow opening which is too narrow to admit the axial member of the plug. As indicated in Fig. 1, the axial member 2 of the plug engages and is held by the U-shaped spring socket member 18 whilst the plug ring member 6 abuts the socket ring member 25 sunk in a recess as shown. This recess is narrow enough to prevent the plug member 3 engaging the ring 25 whilst the plug is being inserted. The coupling is adapted to screw into a screwtype lamp-holder and is provided with a cap 12. The ring members of the plug and socket may overlap as shown in Fig. 5, and may have inter-engaging spring portions as shown at 39, 40. In this embodiment the external threaded contact 28 is slipped onto the socket portion 30 and is held by screws 32 whilst the cap 34 is of metal and is held by screws 35. In another embodiment the ring contacts overlap and are made respectively with inter-engaging recess and pip whilst in a still further embodiment the plug ring contact comprises a number of bent back tongues to engage a solid ring contact on the socket.

A grinding or polishing machine comprises a working head 7 which consists of a drive motor 8 and a working spindle 10 and is tiltable about a first shaft 6 lying beneath the centre of gravity of the workhead, parallel to the working spindle, and pivotable with a second shaft 4 which is perpendicular to the shaft 6 and secured to a support 3 vertically adjustable on a pedestal 2 ; the bearing pressure of a tool 11 against a workpiece 40 is regulable by a mechanical control arrangement which is stationary in relation to the tilting movement of the working head about the shaft 4 but pivotable with the working head about the shaft 6. The shaft 4, on which is secured a forked member 5 carried by the shaft 6, has an extension supporting an arm 13 having at its outer end a threaded sleeve 14 screw-threadedly engaged by a non-rotatable rod 23 which is axially displaceable by manual rotation of the sleeve 14 by means of rods 36. An adjustable abutment 25 is mounted on the rod and engages at least one spring 27 bearing against an abutment 26 axially movable on the rod and engaging a slotted projection 28 on the working head 7. The other side of the projection bears against an abutment 29 axially movable on the rod and downwardly urged into contact with the projection by at least one spring 30 bearing against an adjustable stop 31 on the rod 23. The height of the tool 11, which may be a grinding or polishing tool, may be initially adjusted by vertical movement of the support 3 to accommodate the height of the workpiece, such as a motor bumper bar, which is mounted on a carriage 39 movable along guides 38. The bearing pressure of the tool on the workpiece is adjusted by axially displacing the rod 23, and, during operation on a curved workpiece, the head 7 pivots about the shaft 6 against the springs 27, 30. The workhead with the control mechanism may be pivoted through 90 degrees about the shaft 4 to a position with the spindle 10 vertical to enable the sides of the workpiece to be ground or polished and the stop 31 adjusted to compensate for the loss of weight of the head. Tubes 32, 33, 34, 35 prevent the entry of dust to the springs and rod 23. The machine may alternatively be arranged with the projection 28 carried by the support arm and the spring mechanism secured to the workhead.

Abstract: 595,228. Tobacco pipes ; cigar and cigarette holders. VINCENT, A. June 29, 1945, No. 16613. Convention date, June 17, 1942. [Class 130] To condense water vapour and nicotine and to cool the smoke inhaled from a pipe, cigar or cigarette holder, a condenser a is placed in the smoke channel. The condenser consists of a hollow metallic tank of cylindrical shape fitted with a filling tube e closed by a cap f which is pierced to allow the escape of vapours emitted by the cooling agent which may be water. The tank is preferably coated with an absorbent material, e.g. cotton. In a modification, the condenser may be surrounded by a helical groove for the smoke, the tank being made in two parts to allow it to be filled. The vapours from the cooling agent escape through a slot which can be closed when the pipe is not in use by rotation of the mouthpiece. The Specification as open to inspection under Sect. 91 describes a further modification wherein a radiator, consisting of a corrugated annular cylinder on the outside of the stem, is connected to the condenser. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in or relating to the recovery of di-alkyl benzene di-hydro-peroxides
IPC: C07C407/00
Filed: 1960-05-16
Abstract: Dihydro-peroxides are recovered from mixtures of oxidation products of dialkyl benzenes of the formula <FORM:0920013/IV(a)/1> wherein each R represents an alkyl group, by a two-phase counter-current non-alkaline solvent system, comprising liquids of different polarities, the separation of the dihydroperoxide being affected in two separation columns connected in series, the solvent of greater polarity being exclusively or preponderantly used as counter-current extraction solvent in the first column and the less polar solvent being exclusively or preponderantly used as counter-current extraction solvent in the second column. Water may be used as the strongly polar liquid and petroleum ether as the less polar liquid. Instead of petroleum ether, hydrocarbons such as hexane, octane, decane, 2-methyl pentane, benzene, isopropyl benzene, 1,3,5-tri-methyl benzene, and 1-methyl-4-isopropyl benzene, or ethers such as dipropyl and dibutyl ethers, may be used.  Instead of water there may be used formamide, furfurol, acetonyl-acetone, diethylene glycol, benzyl alcohol, or other strongly polar liquid.  The oxidation mixture may be passed into the lower part of the first extraction column and upwardly in countercurrent to a flowing body of water.  The dihydroperoxide is almost completely washed out of the oxidation mixture by the water.  The aqueous liquid is led from the bottom of the first column to the upper part of the second column down which it flows in countercurrent to the less polar extraction liquid.  The oxidation mixture extracted with water, and containing the mono-hydroperoxide is led from the top of the first column back to the oxidation stage.  From the bottom of the second extraction column, the aqueous phase containing pure di-hydroperoxide is removed and fed to a further column in which it is subjected to extraction treatment with methyl isobutyl ketone, benzene, or other ketone or aromatic hydrocarbon, capable of extracting the dihydroperoxide from the water.  The organic solvent may subsequently be removed e.g. by vacuum distillation. The organic phase leaving the top of the second extraction column may be passed through an adsorption tower, containing alumina, where it is freed from any monohydroperoxide.  If desired the organic phase may be circulated several times through the second extraction column, without passing through the adsorption tower, and the monohydroperoxide from this phase may be recovered by distillation or other means and returned to the oxidation stage. Examples describe the recovery of m-di-isopropyl-benzene dihydroperoxide and of p-di-sec.butyl-benzene dihydroperoxide from appropriate oxidation mixtures.
