Title: Reduction of isomeric impurity in diphenylol propane
IPC: C07C39/16
Filed: 1965-07-20
Abstract: 2,2 - (2,41 - Dihydroxy - diphenyl) - propane is isomerized into 2,2-(4,41-dihydroxy-diphenyl)-propane by a process comprising:  (a) maintaining a mixture of the isomers in an environment of phenol containing dissolved hydrogen chloride at a temperature to keep a substantial part of the mixture in the solid phase for a period which allows the relative proportions of the isomers to achieve substantially equilibrium by isomerization, the initial proportion of 2,2-(2,41-dihydroxydiphenyl)-propane in the mixture being greater than the equilibrium proportion at the said temperature;  (b) applying a vacuum to the reactor and rapidly removing the hydrogen chloride from the isomers at increasing temperature; and  (c) separating phenol from the isomers by distillation.  The process makes possible the reduction of large proportions of the contaminating orthopara polymer in the para-para compound to much smaller proportions.  The process is preferably carried out at a temperature not exceeding 60 DEG  C. with as small a proportion of phenol to polymers as possible, preferably 2-3 moles per mole of polymer.  The process is particularly applicable to the treatment of diphenylol propane obtained by the condensation of acetone with phenol.

Abstract: 830,996. Pneumatic conveyers. JEANNE, E. Oct. 2, 1957 [Oct. 18, 1956], No. 30899/57. Class 78 (1). ). In a conveying system for greasy wool, the conduit has a smooth internal surface and means are provided for spraying a liquid, e.g. water, at least into its entrance zone. The crosssection of the conduit may be square, rectangular, circular or oval. Water is sprayed into the conduit 5, Fig. 1, at the points 11, 12. At each point an orifice 16, Fig. 3, in the wall of the conduit is connected by a pipe 15 to a cistern provided with a ball valve. The orifice is at a higher level than the surface of the water in the tank, but the reduced pressure existing in the conduit ensures the flow of water. A valve 21, Fig. 2, near the inlet 4 to the conduit is adjusted to open whenever the pressure in the conduit falls below a predetermined value which is necessary for efficient operation. The valve actuates a switch K which controls the operation of the charging device 3. The outlet of the device 3 is disposed above the hopper 4.

Title: Improvements in or relating to manometers
IPC: G01L19/00
Filed: 1958-09-30
Abstract: 876,207. Pressure gauges; indicating-apparatus. HARRISON, P. Nov. 12, 1959 [Sept. 30, 1958], No. 31132/58. Classes 106 (2) and 106 (4). A manometer assembly comprises a pair of rigid side frames 5 mounted for angular adjustment about a horizontal axis 0, upper and lower tube header blocks 7, 8 each adapted to receive a pair of manometer tubes 13 and having valvecontrolled passages for varying at will the fluid connections to the ends of the tubes, and means for clamping a number of header blocks side by side between the ends of the side frames 5. Fig. 4A is a section of an upper header block 7 showing only one of the pair of tubes 13 connected to it and Fig. 9 is a section, normal to that of Fig. 4A, showing a lower header block 8. The upper block has two transverse valve chambers 19, each containing a pair of valves 43, 44 which are operable independently of one another to connect the tubes 13 either to a fluid pressure connection 37 or to an exhaust 38. A pair of bores 9 run through the block and bolts (not shown) pass through these and the side frames 5 to clamp the blocks 7 in position. Similar bores are made in the lower blocks 8. These blocks contain longitudinal passages 22 in which " dumb-bell " connectors 27 may be inserted. These serve to connect pairs of tubes 13 at their lower ends. Alternatively, several sets of tubes may be interconnected by the use of different connectors. Mushroom valves 29 are used for sealing or opening at will the lower side of the passage 22. This may be connected to an exhaust or to a common liquid reservoir. Various combinations of the tubes are thus made possible. To reduce fluctuations in level in the tubes 13 due to pulsations in the pressure lines leading thereto, valves 20 in the lower blocks 8 may be partially closed. Also, in the event of fracture of a tube 13, the valves 20 may be completely closed to prevent too great a loss of liquid. Also described (Fig. 12) is an apparatus for indicating the liquid levels in the tubes (which may be illuminated from behind to render reading easier). This consists of a horizontal arm 57 attached to a slider 56 running over a scale 58 on one of the side frames 5. To prevent parallax errors when reading the level of liquid in the tubes, the horizontal arm 57 has a transparent plastic insert 67 on which are engraved two sight lines 65, 66 which may be viewed through a hole 68 in the slider 56 and which are used as a reading edge for the arm 57 against both the liquid column and the scale 58. The slider may be counterbalanced by a weight housed within the side frame and connected to the slider by a tape or cord. This tape or cord passes over a pulley at the top of the frame and rotation of the pulley may operate an indicator or recorder to show the amount of adjustment of the slider.
