Title: Olefin hydration catalyst
IPC: C07C67/00
Filed: 1975-01-14
Abstract: 1476534 Hydration of olefins to alcohols and ethers NATIONAL DISTILLERS & CHEMICAL CORP 14 Jan 1975 [14 Jan 1974] 1572/75 Heading C2C [Also in Division B1] Olefins are hydrated in the vapour phase to give the corresponding alcohols or ethers in contact with a catalyst comprising phosphoric acid impregnated into high-silica glass beads of specified physical properties (see Division B1). Specified feeds are propylene, butylene and ethylene, the last to give ethanol and diethyl ether. Hydration conditions specified include 235-350 C., a pressure of 500-1500 p.s.i., a mole ratio of water/olefin of 0À4-2À0 and a feed rate of 5-100 SCM/feet<SP>3</SP>. The examples describe the hydration of ethylene to ethanol and ether (Examples 1-3) and the hydration of propylene to isopropanol and isopropyl ether (Example 4). The ether product may be separated in a stripper column leaving a dilute alcohol solution which may be further hydrogenated to convert by-product carbonyl groups or unsaturated compounds such as acrolein to alcohols, followed by recovery of alcohol by distillation.

Title: Improvements in or relating to illuminating projectors
IPC: F21S8/12
Filed: 1937-01-20
Abstract: 490,933. Light projectors. PINTSCH AKT.-GES., J. Jan. 20, 1937, No. 1741. Convention date, Jan. 30, 1936. [Classes 75 (ii) and 75 (iv)] A light projector for use on vehicles or for illuminating flying grounds comprises a light source 2, a condenser system formed by a plurality of lenses 3 of short focal length arranged side-by-side in the form of a crown, reflector means (mirrors or prisms 19) for deflecting lateral light from the condenser lenses, or the outer ones thereof, into the main beam, and an objective lens 8 of comparatively long focal length having its focal plane at or near the emergent face of the condenser, or of an apertured diaphragm 17 closely in front thereof. The objective lens may be made in two parts, the centres of which are displaced horizontally in relation to one another, in order to avoid the formation of dark spaces on the road. The crown of lenses 3 may be completed by complementary spherical mirrors 4, and the lenses 3, with or without the prisms 19 and the bulb 2, may be mounted on a fitting 21 which is readily removable from the lamp casing 1 for cleaning or adjustment purposes. The lower and upper edges of the projected beam may be controlled by means of a transparent screen 18 or a deflecting prism, and a movable screen 11, respectively, whilst the length of the casing 1 may be shortened by using a reversing mirror 15 with or without a diverging lens. As shown, the mirror 15 comprises a very thin disc of plate glass 14 which is silvered on the back and mounted on a strong and smooth flat glass plate 16. Alternatively, the disc 14 may be replaced by a plano-concave diverging lens. The mirror 15 may be tilted against the action of a blade spring 6 by means of an electromagnetically operated bolt 7 controlled by a press button at the driver's seat. By means of a step wheel, each depression of the button tilts the mirror a step further, and by means of a second button the mirror springs back step-by-step. Depression of the mirror 15 may be accompanied by a simultaneous dimming of the bulb 2, and the method of operating the mirror 15 may be applied to the screen 11. The bulb 2 may be disposed below or above the lens 8, and near illumination obtained by residual light rays falling on a parabolic reflector 9 and being projected through an unsymmetrically grooved diffusing disc 10. Specification 477,886 is referred to.

Abstract: 875,207. Double windows. EMBERLAND, G. Jan. 19, 1959 [April 10, 1958], No. 1984/59. Class 20(3) [Also in Group XXV] An outwardly opening double window comprises a frame 18 and two casements 21, 22 connected together along adjacent sides by non- separable hinges and each adapted to be releasably hinged along its other side to different sides of the frame. The non-separable hinges permit relative axial movement between their parts, the lower hinge, Fig. 3, comprising a plate 32 fixed to the casement 22 and having a socket 27 slidable on the hinge pin 28 and a small socket 36 loosely pivoted to one end 30 of a lever pivoted on a pin 33 to the casement 21. Each casement is pivoted to the frame by means of lift-off hinges 1, 2, so that, when both sets of lift-off hinges are connected, downward movement of the end 37 of the lever lifts the casement 22 off its hinges whereas upward movement of the end 37 would similarly disconnect the casement 21.

Abstract: 689,560. Transformers. BRITISH THOMSON-HOUSTON CO., Ltd. Jan. 28, 1952 [Feb. 3, 1951], No. 2279/52. Class 38 (ii). An electric transformer comprises a casing 1 which includes a cover 4 secured to the side wall 2, the cover 4 being provided with orifices therein, and the transformer windings 3 being mounted within the casing. Removable terminal structures comprising insulating bushings 6 are attached to the cover by means of flanges 8 so that the portion 9 of the bushing projects into the casing through the orifices in the cover, a pocket 10 of insulating material being secured to the cover so as to enclose the portion 9 of the terminal bushing. Gas-tight joints are provided between side wall and cover, between cover and pocket; and between pocket and electrode 12, this electrode being connected to the windings 3 so that connection may be made thereto by way of terminal 5, extending through the bushing 6, and the portion 7 thereof, which together with portion 13 of the electrode 12 forms a plug and socket connection.

Title: Improvements in or relating to bleaching cellulose-containing fibres for instance cotton, by means of solutions of per-compounds
IPC: D06L4/12
Filed: 1935-01-25
Abstract: Cotton, linen, jute, hemp, ramie, artificial silk, and other cellulose fibres are bleached with peroxides or other per-compounds at a pressure of at least 1.5 atmospheres above atmospheric pressure and at temperatures exceeding 80 DEG  C. and preferably 100 DEG  C. or more.  The active agent may be hydrogen peroxide, sodium peroxide, or sodium perborate.  The pressure may be produced hydraulically, by a pump, by pressure of a circulating bath, by expansion of the treatment liquid in a closed completely filled kier or by gas pressure.  The alkali content of the bleaching bath is preferably low.  Caustic soda, or sodium silicate may be used.  The decomposition of the peroxide may be regulated by the addition of catalysts or of inhibitors.  Iron apparatus may be used provided it is protected with a lime or magnesia cement coating.  The process may be preceded by pressure boiling the materials with solutions of caustic soda, sodium carbonate, or lime.  The materials may be treated with acid between the bucking and bleaching processes.  The bleaching liquor may be applied cold to the materials so that on warming up in the closed kier pressure due to expansion is produced. The kier is opened to remove the enclosed air, then closed and the materials are boiled under pressure.  The materials treated may be in loose form, or in the form of slivers, yarns, knitted or woven fabrics. In an example, cotton fabric is heated under pressure with caustic soda and sodium carbonate.  It is washed and then heated at 110 DEG  C. and under a pressure of 3 atmospheres above atmospheric with hydrogen peroxide and water-glass.  In another example, slivers or knitted goods are heated under pressure with hydrogen peroxide, caustic soda, and water-glass.  In another example, cotton goods are boiled under pressure with lime, washed, acidified, washed, and boiled under pressure with hydrogen peroxide and water-glass.

In the furnace shown, the inner end of the chamber 7 extends across the full width of the treatment chamber and its side walls taper towards the flue. The arched roof 13 of the chamber is located approximately half way between the charging opening and a removable hearth 3, and forms the lower wall of a combustion chamber 8 fired by three burners 16. The flue 11 communicates with a stack through an outlet controlled by a damper 12. In use, the work pieces 2 are charged on to the hearth to a height not exceeding that of the roof 13 so that the flames do not impinge directly thereon.
