Abstract: A fire resistant functional fluid finding application as a lubricant, heat transfer agent, quenching medium, or a power transmission fluid, consists of one or more liquid triaryl phosphates each containing at least 19C per P and having a viscosity of 80-550 SUS at 100 DEG F., mixed with up to 15% of polystyrene of molecular weight 10,000 to 100,000.  The preferred phosphate is the tertiary phosphate ester of cresylic acid.  Small amounts of a rust inhibitor (barium petroleum sulphonate), an anti-wear additive (ditallyl hydrogen phosphate) and an anti-foam agent (a polysiloxane), also may be present. The fluids may be used in hydraulic systems, piston-type pumps, and air compressors (e.g. in the hydraulic systems of die casting systems, metal presses, forging presses and high temperature furnaces).ALSO:A fire-resistant functional fluid finding application as a lubricant, heat transfer agent, quenching medium or a power transmission fluid, consists of one or more liquid triaryl phosphates each containing at least 19C per P and having a viscosity of 80-550 S.S.U. at 100 DEG F., mixed with up to 15% of polystyrene of molecular weight 10,000 to 100,000.

IPC: C08G69/04
Filed: 1965-03-19
Abstract: 1,140,526. Purifying polyamides. ICI FIBRES Ltd. 23 Feb., 1966 [19 March, 1965], No. 11692/65. Heading C3R. [Also in Division B1] A separator for molten polyamide/steam mixtures flowing from a pipe in continuous polymerization apparatus consists of a flared expansion outlet conduit for the pipe, the outlet conduit being internally coated with a polyorgano-siloxane to prevent accumulation of polyamide on the walls. Preferably the outlet conduit leads into the side of a vertical vessel having one or more outflow orifices at the bottom and a vented top. The siloxane is applied to the conduit in the form of a solution in an organic solvent, such as benzene, toluene, ether or acetone, which is subsequently evapoated. The continuous polymerization apparatus may comprise a stainless steel coiled tube with a separator in the form of flared outlet conduit fitted thereto. An aqueous solution of polyhexamethylene diammonium adipate containing 2% of carbon black or 0.3% TiO 2  is pumped therethrough, molten polyhexamethylene adipamide and steam issuing from the separator.

Title: Automatic recording apparatus
IPC: G01R13/00
Filed: 1963-03-25
Abstract: 1,024,578. Recording-apparatus; photo-electric measurement. ESSO RESEARCH & ENGINEERING CO. March 25, 1963 [April 16, 1962], No.11710/63. Headings G1A and G1J. An automatic luminometer for use in testing fuels comprises a liquid fuel sample holder 19a with a wick therein, a photo-electric cell circuit providing an electric signal on lines WP-2 proportional to the light intensity of the flame of the ignited wick and a thermocouple circuit providing an electric signal on lines WP-1 proportional to the temperature above the flame, the two signals being applied to a recorder 4 respectively to move a pen assembly 26 along a guide 21 on a carriage 20 and the carriage 20 across a chart, and a control circuit including a motor 5 for raising and lowering the wick, an electromagnet for depressing the pen to begin recording before a predetermined rating level is reached and to lift the pen after that level and relay RY-1 cutting off the power line, to allow the sample to be changed. A test cycle is initiated by pressing push buttons PB-1, PB-2, whereupon relays RY-1 to RY-5 are energized and maintained by relays RY-1 and RY-2. Relays RY-3, -4 cause the motor 5 to raise the wick at a slow speed controlled by the potentiometer POT-1 switched in by relay RY-5 and set to the rate of increase of luminosity specified by the test procedure being applied. As the lamp warms up the carriage 20 moves from left to right and when a cam 29 thereon strikes a micro-switch 30 (MS-1), preset along an overhang 28, terminal B momentarily contacts terminal A, locks relay RY-6 through RY-2, causing depression of the pen 26a to record thereafter continuously, luminosity against temperature. As the luminosity approaches the "rating level a miniature snap action switch 24 (MS2) is opened momentarily by a cam 27 on the pen assembly 26. Relay RY-7 is thus de-energized and causes energisation of relays RY-8 and RY-9, the latter only for the 10 secs. needed by a heater circuit in time delay relay RY-8 to open circuit through relay RY-9. For these 10 secs. the output of the luminosity circuit is returned to earth through resistance R1 which is equal to the input resistance of the voltage dividing circuit between the photo-cell and first amplifier tube and so provides a reference value for zero luminosity to correct for any drift in the D.C. amplifier. At the end of 10 secs. the luminosity circuit is reconnected to the recorder and after the luminosity reaches a preset value above the "rating level", a micro-switch 25 (MS-3) is momentarily opened by cam 27 and deactivates relay RY-2 which in turn deactivates relays RY-3 to -6. Relays RY-3, -4 reverse the polarity of the wick drive motor and relay RY-5 switches over potentiometers POT1 and 2 so that wick is lowered at high speed. Relay RY- 6 lifts the pen and during the return of the carriage to initial position switch 30 (MS1) deactivates relay RY-1 which shuts off the power.

Apparatus for punctuating and suppressing zeroes in units of data emanating from a computer or the like, comprises means for suppressing and storing the first character of each unit (e.g. a ú or $ sign), means for suppressing each following non-significant character (e.g. zeroes), and means for inserting the first suppressed character as the first character of the altered data unit. The apparatus shown edits data received at terminals 41 and passes the edited data via terminals 42 to a printer. The circuits include AND gates (represented by rectangles) and amplifiers (represented by triangles), each amplifier effecting a half-bitperiod delay. A data unit normally comprises a number with zeroes in the higher denomination preceded by a pound or dollar sign and followed by " + " or " -," and the six code bits plus parity check bit P representing each character of a word are received in parallel by amplifiers 43 which supply true and inverted forms to amplifiers 44, appropriate outputs of which are applied to special character detectors 45-48. These detectors control circuits including pulse-recirculating flip-flops 53, 57, whereby the monetary sign and immediately following non-significant characters (" 0 " 's  and commas) are replaced by " space " characters under control of amplifiers 63, 67, and the monetary sign is inserted immediately before the first significant digit of the number under control of a " zero " output from amplifier 71, the " + " sign also being optionally suppressed.

IPC: C04B2/04
Filed: 1954-04-29
Abstract: <PICT:0763110/III/1> Lime is hydrated and separated from coarse particles by air separation or screening, the coarse particles are agitated with water and the so-formed suspension used to hydrate further lime. The term "lime" includes calcined limestone, dolomite and precipitated calcium carbonate.  In the apparatus shown in Fig. 1, tailings from the air separator or screen and water are supplied through pipes 10 and 12 to a hopper 11, pass into a centrifugal pump 14 and thence are conducted to a wet cyclone 16 from which a slurry of fine particles is returned via line 18 to the hydrator. Coarse particles leave via line 19, but are washed before so doing by a counter-current stream of water from line 21 to avoid the loss of fine particles.  Other figures (not reproduced) show (1) the recycling of all or a part of the coarse materials back to the hopper 11 and (2) the use of an agitating tank in place of the hopper 11 having a rotating agitator located within the lower part of a vertical cylindrical baffle into which the water and tailings are passed; the material passed to the pump is generally withdrawn from the top of the agitating tank and coarser particles may be withdrawn from the bottom thereof: the wet cyclone may be omitted.  In other embodiments the separation step may be omitted and the mixture of tailings and water passed through a wet mill; differing degrees of disintegration may be applied to the suspension of tailings, e.g. simple mixing, or violent turbulence as by the use of a ball rod or tube mill employing rubber-coated balls or rods; the wet cyclone could be replaced, e.g. by a wet screen or sedimentation classifier: and in a plant in which lime is removed from the dust-laden hydrator steam with simultaneous preheating of water for hydration, this preheated water is preferably used to mix with the tailings,
