Title: Improvements in the process of manufacturing chlorinated derivatives of perylene
IPC: C09B3/20
Filed: 1925-04-14
Abstract: Chloro-perylenes are prepared by treating a solution or suspension of perylene with chlorinating agents or with a current of chlorine. Solvents or suspension agents mentioned are chlorbenzene, carbon tetrachloride, glacial acetic acid, carbon bisulphide and chloroform; water and dilute sulphuric acid are excluded as leading to the formation of oxidation products. According to the examples, (1) chlorine is introduced into a boiling solution of perylene in glacial acetic acid containing a trace of iodine; the precipitate formed on cooling can be separated by crystallization from toluene into two chloroperylenes melting at 278 DEG  C. and 325 DEG  C. respectively; (2) to a suspension of perylene in chloroform containing a trace of iodine, sulphuryl chloride is slowly added and the reaction mixture boiled; on cooling, a product is precipitated from which, by repeated extraction with benzene, a chloroperylene of m.p. 180 DEG  C. can be isolated; by crystallization of the residue from nitrobenzene, a perylene tetrachloride of m.p. 310 DEG  C. is obtained; if double the quantity of sulphuryl chloride be employed in the reaction, a perylene tetrachloride of m.p. 294 DEG  C. results.

Title: Throttle valve actuator for an automatic vehicle transmission having engine back pressure compensation
IPC: F16H59/30
Filed: 1972-09-02
Abstract: 1356543 Change-speed gear control FORD MOTOR CO Ltd 2 March 1972 [28 April 1971] 9740/72 Heading F2D A change-speed and reverse gear transmission driven by an engine through a hydrokinetic torque converter is controlled by a circuit receiving signals dependent on vehicle speed and engine torque which has means to combine engine manifold pressure with exhaust back pressure to improve the accuracy of torque representation when accessories such as emission control devices produce significant back pressure. As shown a throttle valve actuator 108 comprises diaphragms 132, 144 within a housing 114 forming chambers 166, 176, 178 and having an operating stem 134 attached to the diaphragm 132 to actuate a throttle valve spool 162 controlling the pressures applied to the shift valves. A spring 138 positions the diaphragm 132 in the absence of actuating pressures and engine manifold pressure is applied to the chamber 178 through a passage 110 while this is opposed by exhaust pressure applied to the chamber 176 through a passage 112 while chamber 166 is kept at atmospheric pressure through a port 164 so that the resultant pressure applied by the stem 134 on the spool 162 is dependent on exhaust back pressure as well as engine manifold pressure thus more accurately representing engine torque. In a modification only one diaphragm corresponding to 132 is used, the spool side being formed into two chambers by evacuated bellows. One of these chambers has exhaust pressure applied while the other is kept at atmospheric pressure.

Title: Power transmission device in particular for a submarine camera
IPC: H02J13/00
Filed: 1973-02-28
Abstract: 1391162 Remote control system THOMSON-CSF 28 Feb 1973 [3 March 1972] 9837/73 Heading G4H A system for transmitting power and data signals along a single cable 1 comprises a switching circuit 9 which stores a received control command for devices 10, 11 and temporarily blocks any other command transmitted thereto. As described, the system is a submarine TV system, the sheathed coaxial cable 1 connecting a power unit 2, a control unit 3, a demodulator 4, a multiplexer and encoder 5 and a filter 6 on board a ship, to a hermetically sealed enclosure containing a filter 7, a decoder 8, circuit 9, lamps 10, 11, a camera 14 and a modulator circuit 13. Circuit 9 prevents parasitic signals from producing unwanted lighting up and extinction of the lamps, and allows the supply current to a lamp to stabilize after that lamp has been switched on. The circuit has a power input 70 and control inputs 90, 91 (one for each lamp), to which are applied on/off signals (1, 0 levels respectively); it consists of differentiators 20, 120, AND gates 21-122, monostables 23-124 (stable output at the 1-level), and two-thyristor stores 25, 125. A 1-level signal to, e.g. input 90 (to light lamp 10) is differentiated at 20 and applied to gate 21 to enable it (with the help of the outputs from 24-124). The output from 21 causes one of the SCRs in 25 to connect power input 70 to lamp 10, and at the same time triggers monostable 23, whereupon gates 22-122 are blocked as long as 23 remains in its 0-level astable state. The power unit 2 (Fig. 3, not shown), incorporates means (41-45) connected to the outputs 32, 33 of unit 2 for temporarily clamping the power output to a predetermined (stable) value when either lamp is lit. A feedstock loop (50-57) is also incorporated which blocks the output to provide protection against current surges.

Title: An automatically acting device for locking the doors of steaming chambers
IPC: F23M7/00
Filed: 1919-04-22
Abstract: 137,714. MeDowall, Steven, & Co., and Cunningham, P. April 22, 1919. Pneumatically-controlled fastenings.-A steaming-chamber has automatically acting means for preventing the door of the chamber being opened whilst there is steam-pressure in the chamber. As shown, a piston 1 has its lower face in communication with the steam chamber by a passage 3. Pressure in the chamber raises the piston into the path of a projection on a bolt securing the door. When steam has been cut off the pressure in the chamber may be relieved by a cock 11, when the piston falls, allowing the door to be opened. Grooves 10 in the piston allow air to enter the chamber to relieve a vacuum. The piston may itself constitute a sliding-bolt for the door.

Abstract: PCT No. PCT/GB89/01497 Sec. 371 Date Jul. 23, 1991 Sec. 102(e) Date Jul. 23, 1991 PCT Filed Dec. 14, 1989 PCT Pub. No. WO90/07020 PCT Pub. Date Jun. 28, 1990.A two-stage method of producing N2O5 in nitric acid from N2O4 in nitric acid consists of a first production stage in which the anodic oxidation of N2O4 in nitric acid and cathodic reduction of nitric acid are separated by a non-ionic or anionic ion exchange membrane, and a second production phase in which the product of the first stage anodic reaction is subjected to further anodic oxidation, the anodic and cathodic reactions being separated by a cationic ion exchange membrane. The use of a cationic membrane in the second stage promotes, through leakage of N2O4 to the catholyte, an increase in N2O5 concentration and decrease in N2O4 concentration within the anolyte acid while avoiding a significant loss of current efficiency. The two stages may be connected in series and operated continuously to produce a nitric acid solution containing typically 32 wt. % N2O5 and less than 2 wt. % N2O4.

IPC: G06K19/10
Filed: 1988-01-06
Abstract: PURPOSE:To avoid an unfair access and to improve the property of security by releasing a collated state for one code number when the collated state becomes normal once in one collation, however, it becomes abnormal in another collation after that. CONSTITUTION:An IC card as a portable electronic device is composed of parts to execute basic functions such as a reading and writing part 11, a code setting and code collating part 12, and an enciphering and decoding part 13, and a supervisor 14 to control these basic functions. Further, while the IC card sets identifying information to indicate that the collated state is normal when the collation of the code number is completed normally, the ID card resets the identifying information when the collation is completed abnormally. Consequently, when the collated state for one code number becomes normal once in one collation, however, it becomes abnormal in another collation after that, the collated state is released. Thus, the unfair access can be avoided, and the property of the security can be heightened.

Filed: 1996-01-09
Abstract: PROBLEM TO BE SOLVED: To save water at bathing. SOLUTION: A bathroom 5 has a steam outlet 6, and a divergent nozzle pipe line 9, and a suction port 10, and a hot water supplying means 12 are successively continued and connected on the upstream side of a shower head 8. Steam is supplied to the bathroom 5 through the steam outlet 6 to heat the bathroom 5.  Since the flow velocity is increased near the minimum pipeline area of the divergent nozzle pipeline 9 when hot water is supplied from the hot water supplying means 12, and the static pressure is reduced by the Bernoulli's theorem to suck the heated air within the bathroom 5 through the inlet port 10 by the pressure difference with the outside air pressure, the reduction and fluctuation of the shower hot water temperature by air inclusion can be suppressed, and the quantity of hot water can be reduced to save the water without giving a thermally uncomfortable feeling to a bathing person.
