Patent GB-1092087-A (GB)
Title: An improved process for the fluorination of aliphatic chlorohydrocarbons
IPC: C07C17/38
Filed: 1964-11-13
Abstract: Some or all of the chlorine atoms in aliphatic chlorohydrocarbons are replaced by catalytic reaction with anhydrous hydrogen fluoride by a process effected in two or more consecutive stages, in the second and each subsequent stage of which the hydrogen fluoride present in the reaction gases effluent from the preceding stage is further reacted by feeding therein additional amounts of said chlorohydrocarbons in a molar excess with respect to the hydrogen fluoride present in that stage, thus resulting in substantially no hydrogen fluoride being present in the reaction products of the final stage. Non-fluorinated or partially fluorinated chlorohydrocarbons may be separated from the reaction products of the final stage and recirculated to a preceding stage.

Abstract: 1,254,273. Springs. OTTER CONTROLS Ltd. and J. C. TAYLOR. 9 Jan., 1969 [13 Oct., 1967], No. 46885/67. Addition to 1,064,643. Heading F2S. [Also in Divisions H1, H2 and H5] A snap-acting spring comprises a rectangular bimetal sheet 26 from which a U-shaped portion 27 has been cut to release a central tongue 28 flanked by outer legs 29, 30, the legs 29, 30 being bridged opposite the free end of tongue 28, the bridging portion being crimped to draw the ends of legs 29, 30 together to impart a dished configuration to sheet 26, which is thereby stressed so as to snap between oppositely dished positions with changes in temperature. Tongue 28 carries a plastics block 33 which overlies legs 29, 30 and acts as a stop to define the position of tongue 28 in the hot position and thus predetermine the temperature at which the sheet will snap to its cold condition with falling temperature. The bimetal forms part of an electric switch (see Division H1).

Title: Fuser control circuit for copying apparatus
IPC: G05D23/24
Filed: 1972-10-11
Abstract: 1406655 Heat fusing: automatic temperature control XEROX CORP 11 Oct 1972 [18 Oct 1971] 46895/72 Headings G2H and G3R Copying apparatus has an automatic fuser temperature control using a temperature variable resistor sensing the fuser temperature, an amplifier and a heater, which is switched off at a pre-set fuser temperature, actuation of the copying apparatus being prevented when the fuser temperature is below a predetermined minimum. In the embodiment, the fuser temperature is sensed by thermistor 45. For temperatures below the predetermined minimum, switching amplifier 55 is triggered on to energize relay 60', 60 and thus turn on heating lamp 44 in the fuser. At the minimum temperature and above, the output across thermistor 45 turns operational amplifier 50 on, amplifier 55 remaining on, and an amplifier 56 being triggered on to close relay contact 63, allowing the copying apparatus 10 to be operated upon closure of switch 69. At the required temperature, set by biasing resistors 58, 59, amplifier 55 turns off to terminate the heating. The required temperature is maintained by switching of amplifier 55. If the fuser temperature falls below the minimum value, amplifier 56 turns off to stop the apparatus 10. Similarly if the temperature rises above a pre-set maximum, and a time delay set by circuit 72 has elapsed from the starting of the apparatus, amplifier 57 is triggered on to open relay contact 67, stopping the apparatus 10 and sounding an alarm. Contact 67 may be manually reset. Amplifier 57 may also stop the machine if the thermistor fails, in which case, transistor 70 is turned off, to turn off amplifier 50.

Title: Continuous Degassing of Steels
IPC: C21C7/10
Filed: 1968-10-03
Abstract: 1,192,856. Degassing steel. CONZINC RIOTINTO OF AUSTRALIA Ltd. Oct. 3, 1968 [Oct. 3, 1967], No. 47020/68. Heading C7D. In a process and apparatus for the continuous degassing and deoxidation of molten steel the latter is admitted through a barometric inlet pipe into the upper part of a vacuum vessel where it is subjected to electromagnetic stirring before being discharged from the upper part of the vessel through an outlet pipe. Degassing may be facilitated by the introduction of finely divided solids such as carbon or ferrosilicon, or of inert gases such as argon, the latter being introduced along the inlet leg. As illustrated, molten metal in launder 5 passes through inlet leg 6 into vacuum vessel 2, where it is stirred by coil 8 and may be heated by elements 11, before leaving by pipe 7. The system is self-regulating in that any violent evolution of gas from the fresh incoming metal increases the pressure in chamber 2 and thereby reduces the rate of inflow of metal. The degree of degassing may be controlled by adjusting the intensity of stirring.
