Title: Method for producing hexafluoroisopropanol and fluoromethyl hexafluoroisopropyl ether (sevoflurane)
Inventor: YUZURU MORINO
IPC: C07C49/167
Filed: 2016-12-02
Abstract: Disclosed is a method for producing a hexafluoroisopropanol, including the steps of (a) purifying a mixture containing hexafluoroacetone and at least 1,1,1-trifluoro-2,2-dichloroethane as an impurity, thereby obtaining a purified hexafluoroacetone containing 120 ppm or lower of the 1,1,1-trifluoro-2,2-dichloroethane; and (b) bringing hydrogen (H2) into contact with the purified hexafluoroacetone in the presence of a catalyst, thereby hydrogenating the hexafluoroacetone into the hexafluoroisopropanol. It is possible by this method to produce the hexafluoroisopropanol with a short reaction time and a high conversion. Therefore, it is possible to particularly advantageously produce fluoromethyl hexafluoroisopropyl ether (sevoflurane) by using the hexafluoroisopropanol produced by the method.

Title: Intelligent pressure-controlled pressure cooker
Inventor: XIANFENG WU
IPC: A47J27/08
Filed: 2019-09-17
Abstract: The present application provides an intelligent pressure-controlled pressure cooker, comprising a pot body, a pot cover, a safety valve, a linkage mechanism and an electromagnetic attraction mechanism. In application, if the air pressure in the pot body is higher than a preset value, a pressure relief body in the safety valve is jacked up to form a gap, and gas is discharged from the pot body through the gap to realize pressure control. When gas needs to be discharged, the electromagnetic attraction mechanism is started, and a magnetic float is adsorbed by magnetism to form a moving action; in addition, the formed moving action is transmitted to a gas discharge body through the linkage mechanism to rotate the gas discharge body, so that first gas discharge holes and second gas discharge holes are communicated to form a gas discharge passage, and the gas in the pot body is discharged. According to the present application, two operations of pressure control and gas discharge can be accomplished through one safety valve, avoiding arranging multiple valve bodies on the pot cover, and improving the reliability of the pressure cooker. In addition, the gas in the pot body is discharged through electromagnetic adsorption, avoiding manually starting a gas discharge valve, and reducing the scald probability.

IPC: F28F19/00
Filed: 1965-12-07
Abstract: 1,119,772. Cooling liquids in bulk. BOLIDEN, A.B. 3 Dec., 1965 [7 Dec., 1964], No. 51404/65. Heading F4S. A liquid, particularly a highly corrosive liquid such as hot sulphuric acid, is cooled in an upright (cylindrical or oval) chamber by a fluid coolant such as sea water which circulates through groups of tubes 9 (either U-tubes or Field tubes being preferred) each group comprising a radial series of tubes interconnected through header compartments in a structure forming the top cover for the chamber, and the total tube crosssectional area of a group increasing progressively outwardly from the centre of the chamber. The cover structure comprises a lid 5 in which are formed sector-shaped openings. These are closed by header sections (See Fig. 2) from which the tubes extend into the chamber. Each section has its own inlet and outlet 11, 12 leading to main header 17, 18. The liquid to be cooled enters the chamber through an inlet 2. An impeller acting against the inlet stream, causes continuous recirculation of liquid within the chamber to somewhat reduce the temperature of the liquid before it contacts the tube surfaces. Contact by the corrosive liquid with the joints between the tube ends and the headers is prevented by the provision of a cylindrical baffle 6 extending downwardly from the lid 5. The baffle causes a gas pocket to be formed above the liquidas the level rises. Wave shaped inserts may be inserted into the tubes to create turbulence in the coolant. These inserts are preferably of a material more readily ionizable than that of the tubes whereby any tendency to galvanic corrosion, will erode only the inserts. The coolant is maintained at a higher pressure than that of the container liquid to prevent the entry of corrosive liquid into the tubes in the event of leakage. The tubes and headers are of stainless steel and may be lined with copper.

Abstract: 1310932 Windows W FRACH 20 Feb 1970 [20 Feb 1969] 5723/70 Heading E1J [Also in Division F2] A control device for hydraulically sealing or holding a window by pressure hoses 1, 2, 3 comprises two rotatably mounted pinion wheels cooperating with two displaceably mounted gear racks 9, 10 connected to moveable parts of two piston and cylinder arrangements 11, 12. In Fig. 2, shaft 19 is rotated in a clockwise direction to move rack 10 out of engagement with pinion wheel 4 by pressure of cam disk 13 on stop 17 and to move rack 9 into engagement with another pinion wheel behind wheel 4. Piston 12 is drawn towards the pinion wheels by rack 9, producing suction at the cylinder bore to empty hoses 3 and 1 (Fig. 1) which are connected by bores 7 and 8 into the cylinder bore. The window is thus unsealed on all sides except the lower horizontal and is free to tilt about horizontal axis 30. Anticlockwise rotation of the shaft from this position reverses the process to reseal the window until the position shown in Fig. 2 is reached. Continued anticlockwise rotation then releases pressure in hoses 2 and 3 to unseal the window and allow it to pivot about vertical axis 29.

Title: Caprolactam and ammonium sulphate recovered from reaction mixts - with simultaneous neutralisation with ammonia and evaporation of water
IPC: C07D201/16
Filed: 1974-07-12
Abstract: epsilon-Caprolactam and solid ammonium sulphate are recovered from a reaction mixt. of lactam and H2SO4 by neutralising thw H2SO, with ammonia at a superatmospheric pressure of 1-5 at, esp. 1-2 at, while the heat of neutralisation is extracted by evaporating water from the soln. using a circulating volume of (NH4)2SO4 soln. with simultaneous formation of (NH4)2SO4 crystals, separation of the crystals from the liquid phase and separation of the liquid phase into a 'lactam oil' layer which is drawn off and a recirculating layer of (NH4)2SO4 soln. The process is used esp. for treating reaction solns. resulting from the intramolecular conversion of cyclic oximes to the corresponding lactams with acids, allowing combined sulphuric acid neutralisation and crystallisation of the (NH4)2SO4 from the concentrated soln. The process also obviates the need for vacuum apparatus, while the water evapd. can be recovered as steam e.g. for 1 ton lactam 1 ton of steam at 2 atmos can be obtd.

Patent NL-7811262-A (NL)
IPC: G06K15/10
Filed: 1978-11-14
Abstract: A mosaic printer is made secure from unauthorized interception of data by falsifying the needle drive pulse current magnitude and sequence so that electromagnetic leakage radiation cannot be used to determine the alphanumeric data being printed. This falsification is accomplished by a compensation device having compensators energized each print cycle in addition to the printer needle drives in a reciprocal or a pseudorandom manner. The compensators have current consumption characteristics nominally identical to the needle drives and produce substantially identical radiation pulses, making it impossible to correlate the radiated pulse format with the symbol being printed.
