Title: Process for the manufacture of monomolecular reaction products of unsaturated hydrocarbons of the butadiene series with sulphur dioxide
IPC: C07D333/48
Filed: 1930-07-14
Abstract: Monomolecular reaction products are obtained by treating butadiene hydrocarbons with sulphur dioxide in the presence of small quantities of substances having a stabilizing action on polymerizable hydrocarbons having olefinic double bonds. Examples of such anticatalysts are phenols, especially polyhydric phenols such as hydroquinone, pyrocatechol, and pyrogallol, amines, copper, and salts of copper.  The reaction may be carried out in closed vessels in aqueous solution, or gaseous sulphur dioxide may be forced with a mixture of the diolefinic hydrocarbon and the anticatalyst.  Inert solvents, for example, hydrocarbons such as benzene, may be present. Diolefinic hydrocarbons which may be treated are butadiene-1 : 3, 2-methylbutadiene-1 : 3, 2 : 3-dimethylbutadiene-2 : 3, 1-phenylbutadiene-1 : 3, 2 : 3-diphenylbutadiene-1 : 3, 2-ethylbutadiene-1 : 3, and 2-isopropylbutadiene-1 : 3.  Examples are given, in one of which butadiene-1 : 3 mixed with one per cent of hydroquinone is treated with liquid sulphur dioxide at room temperature for eight days. The crystalline paste formed is dissolved in benzene, small quantities of high-molecular products removed by filtration and the monomolecular product is precipitated in the form of crystals by the addition of petroleum ether.  The substance is presumably dihydrothiophene sulphone.  When smaller quantities of the anticatalyst are used, larger quantities of high-molecular products are obtained which can be separated by their insolubility in suitable solvents, such as benzene, alcohol, chloroform, and water.  Other examples describe the formation of the monomolecular sulphones corresponding to butadiene-1 : 3, 2 : 3-dimethylbutadiene-1 : 3, and isoprene using as anticatalysts pyrogallol, pyrocatechol, copper powder, copper oleate, 1 : 8-naphthylenediamine, and NN<1>-diphenyldiaminoethane.  When isoprene is treated with sulphur dioxide in presence of pyrogallol, high-molecular sulphones are also formed, which can be separated by their insolubility in water or benzene.

Title: Broken-discharge-line indicator for fluid-flow systems
IPC: F16N29/00
Filed: 1962-06-01
Abstract: 989,966. Lubricating systems. EATON MANUFACTURING CO. June 1, 1962 [Sept. 11, 1961], No. 21314/62. Heading F2A. A broken-line indicator for lubricating systems comprises an indicator piston 20, a pilot piston 40 to move the piston 20 to expose an end thereof to line pressure (Fig. 5), and a spring 30 to return the piston 20 to the original position. The piston 20 is moved between lineblocking and line-opening positions (Figs. 2 and 5, respectively) to expose its end to fine pressure, when it protrudes. The spring 30 responsive to a predetermined minimum pressure in the line returns the piston 20 to the left, i.e. to its line-blocking position (Fig. 5), with a broken line. An indicator stem 28 on the piston 20 gives a visual indication of the latter's position. The pistons 20, 40 are arranged in tandem. With normal operation the pilot piston 40 is returned to the left to its original position by a spring 46 acting on the portion 41 which is exposed to line pressure, change in position of the piston 20 actuating an electrical indicator through the stem 28. In a modification instead of a spring 46 difference in area at each end of piston 40 exposed to line pressure is used to return the piston 40. The piston 40 is exposed to line pressure ahead of the piston 20 so that the piston 40 moves the piston 20 to a line-opening position when the line pressure exceeds a selected value, line pressure on the exposed end of the piston 20 thereafter maintaining it in its line-opening position until it is below another selected value. In another form, either or both pistons is/are magnetized and magnetic switch means operates in response thereto to give an indication of the position thereof.

Abstract: 645,920. Positioning cases on roller conveyers. WEBSTER & CO., Ltd., R. W. Aug. 13, 1948, No. 21394. [Class 78 (i)] A case conveyer system comprises means (for example, roller conveyer 1) for advancing cases one by one to a predetermined point along the conveyer path, and movable thrust means for orientating and/or locating each case or package in a pre-arranged manner on and in relation to its support after it has been advanced to and arrested at the predetermined point aforesaid. General, Fig. 1.-Empty case 2 is conveyed along a conveyer by gravity and slides on to platform 3 abutting against a roller 7 and is then pressed transversely by roller 13 so as to be located against rollers 15 and 15<1>. Platform 3 carrying the case is then elevated to a fixed point, bottles are then inserted in the case and the platform and case are lowered to its original position. The next case arriving by gravity pushes the first case over the roller 7 and discharges it down the shoot to the right. As shown, case 2 moves on to platform 3 and abuts against roller 7 mounted on levers 6 resiliently pivoted at 50 on levers 4, the lever 4 being resiliently pivoted at 5. Roller 7 is pressed to the right till the abutment on lever 6 strikes abutment 11 on lever 4 at which point roller and levers pivot together about 5 so that lug 8 strikes valve 9 controlling pipe 10 of a pneumatic system. The pneumatic system operates actuating devices 14, 24 and 19. When valve 9 is operated, actuating device 24 presses pad 25 against the oncoming case so as to check it and device 14 swings over roller 13 pivoting at 51 so that the case on platform 3 is moved transversely to its movement of direction up and against rollers 15 and 15<1>. Rollers 15 and 15<1> each have one fixed roller and one roller movable on an arm about the fixed roller and the movable rollers are rotated on their arms by devices 19 so as to embrace the corners of the case which are thrust against them. Platform 3 now rises carrying the orientated case and releases roller 7 so that lever 4 comes under the influence of its spring and closes valve 9. The closing of valve 9 retracts the actuating devices to their original positions and device 24 retracts pad 25 so that it no longer checks the next case. However, platform 3 releases abutment 23 so that roller 21, which is spring- influenced, rises to check the next case in lieu of pad 25. When the platform rises to a predetermined position bottles are inserted in the case thereon and the platform descends automatically till it presses down roller 7 and also lug 23 of roller 21 so that the case is free to be pushed over to the right by the next case and to slide down the rollers to be discharged, thus allowing this next case to move along on to the platform 3. The diameter of the fluid supply lines to the devices is modified so that the latter operate in the correct sequence.

Abstract: 281,756. Broadbent, A. Sept. 4, 1926. Pneumatic separating; fixed sieves; rotary sieves.-Grain or the like is fed from a hopper down a shoot 24 into an annular chamber 3 situated above a perforated inverted cone member 2 arranged in a similarly shaped chamber 1. Air is drawn through the central opening 4 of the annular chamber by a fan 6 from an inlet 23, the inlet being arranged tangentially to the annular chamber so that the air is given a whirling movement and the grain is thereby moved round the member 2 and so rubbed and scoured. Beaters 10 mounted on a vertical rotating shaft 9 may be used to increase the rubbing action. Dust &c. removed from the grain passes through the screen 1 and accumulates against one or more one-way flaps 12 in a shoot 11, while the heavy grain passes similar one-way flaps in a shoot 14 leading to the air uptake 15, down which the cleaned grain is delivered, any remaining particles of dust being carried by the air current past a baffle 22 into a chamber 21. In a modification, the chamber 1 is cylindrical in shape, and the shaft 9 is provided with a coned distributor to throw the dust &c. to the shoot or shoots 11. In a further modification, the grain passes from the screen 2 to a central opening and the dust &c. is moved outwards by rotating scrapers. The coned screen may be rotated with the shaft 9.

Abstract: 1,148,951. Stabilizing devices. BELL & HOWELL CO. May 17, 1966, No.21910/66. Heading G2J. In an optical system, such as a camera 10, Fig. 1, wherein the image of an object 22 is focused in the image plane 18 by moving a lens 14 relative to fixed lenses 12, 16, to ensure that despite inadvertent movement of camera 10 the image remains in focus, the lens 14 is normally centrally mounted on a carriage 28 which is initially manually or otherwise moved, such as by knob 32 and screw 30, to obtain correct focus and then, when the camera moves, the lens 14 remains substantially fixed in space. This is accomplished by arranging centralizing springs 42, 44, Fig. 3, on either side of the lens carrying arm 24, so that when the camera moves, the arm 24 due to its inertia tends to remain stationary and thus moves relative to the camera causing the output of fixed coils 38, 40, which are supplied from oscillator 41 and co-operate with moving coil 36, to become unbalanced and supply a signal to phase detector 48. This is amplified at 50 and used to urge coil 36, and with it lens 14, away from fixed coils 52, 54, against the action of the centralizing springs 42, 44. In a modification Figs. 4A, 4B and 5 (not shown) electrical off-centre detecting means permit generation of an opposing magnetic field force between coils (62) and (66), (68), which oppose the restoring force of springs (64). Arrangements are also described in which inadvertent linear transverse movement, Fig. 6 (not shown) or rotary motion, Figs. 7-9 (not shown) is compensated.
