Title: Apparatus for producing carbon black
Inventor: HIGGINS NORMAN ROYCE
IPC: B01J19/26
Filed: 1963-10-29
Abstract: <PICT:1068178/C1/1> Carbon black is prepared by injecting a make hydrocarbon feed into a flame formed by burning a fuel gas with a slight excess of air or other free oxygen-containing gas in a reactor 11 having a flared extension 36 at the burner end terminating in an annular closure plate 38 close to housing cover-plate 16.  The flared extension 36 has louvres 37 through which air passes to the burner and acts as a combustion aid device.  The make hydrocarbon is fed through pipe 20 and is directed down the centre of reactor 11 by air fed through inlet 24 and the annular passage between pipes 20 and 18. Fuel gas is fed through inlet 23 and the annular passage between pipes 18 and 17 and passes through holes 22 into the interior of flared extension 36.  Air introduced at inlet 14 is preheated by passage between reactor 11 and housing 10 before reaching the burner. As shown, the louvres are sited for formation of a flame of the centrifugal type, and the spiralling motion of the air may be enhanced by helical vanes in its flow path as illustrated in Fig. 4 (not shown).  Alternatively, for a flame of the longitudinal type, rectangular vanes are used as in Fig. 2 (not shown), and the louvres are arranged at right-angles to the position shown in Fig. 1. Figs. 2 and 4 also illustrate a reactor having a Venturi configuration forming by thickening of the refractory lining 12 of the reactor. This is the subject of Specification 1,068,177.  The reactor is connected to a quench section 26 with a water spray 29.

Patent GB-968390-A (GB)
Title: Manufacture of novel copolyesters
Inventor: GOODMAN ISAAC
IPC: C08G63/60
Filed: 1960-12-19
Abstract: Regularly alternating copolyesters of unit structure <FORM:0968390/C3/1> where R is -CO-, -CO.CO- or -CO.R1.CO-, R1 is an alkylene, cycloalkylene or arylene linkage, X is cycloalkylene or -(CH2)n and n is 2-6 are made by reacting a di(hydroxybenzoate) of a dihydric alcohol with a di-acid chloride of a dicarboxylic acid or carbonic acid.  Reaction may be effected by (a) introducing a solution of the di-acid chloride in a water-immiscible solvent into an aqueous alkaline solution of the di(hydroxybenzoate) or (b) heating the di-acid chloride with the di(hydroxybenzoate) in a high boiling organic liquid (e.g. o-dichlorobenzene or decalin).  As a catalyst, N,N-dimethyl cyclohexylamine may be used.  In Examples (1) and (9) Ethylene di-m-hydroxybenzoate was reacted with phosgene, terephthaloyl chloride or isophthaloyl chloride; (2)-(8) Ethylene di-p-hydroxybenzoate was reacted with oxalyl, adipoyl, sebacoyl, succinoyl, terephthaloyl or isophthaloyl chloride.

Patent GB-1032378-A (GB)
Title: Improvements in or relating to the production of phosphonic acids and their salts
IPC: C02F5/14
Filed: 1964-10-28
Abstract: Water is softened by the addition of phosphonic acids or phosphonates containing at least 2 P atoms in the molecule, e.g. of the formula <FORM:1032378/C1/1> where R is alkyl or aryl prepared in specified manner (see Division C2).  In an example a compound of the above formula where R is methyl was found to inhibit the precipitation of CaCO3 when a soda solution is added to hard water.  Also, precipitation of Fe3+ ions as ferric hydroxide from water containing Fe3+ ions is chlorinated hydrocarbon, but particularly nitrogen, introduced to the system via conduits 8 may serve (a) to convey the oxide, e.g. silica, introduced from separators or storage bins 12 to the reaction vessel 1 via conduit 11, (b) as carrier for A via conduit 11, (c) as carrier for and to dilute, the steam, preferably 100 g./m.3 gas, via 10 to conduit 11, and (d) after prior heating in 9, as source of part of the heat for the reaction. These may advantageously be combined by heating the gas by burning an oxyhydrogen flame, and using this heated gas to convey the reactants, or, in the absence of inert gas steam alone may serve this purpose. The reaction vessel is a vertical tubular furnace 1, heated internally by electric heating elements 6.  The reactants, heated to 200-800 DEG  C., ascend in suspension and the treated oxide passes from settling zone 2 to outlet 3, contact with oxygen being avoided before cooling below 200 DEG  C.  Gases and untreated oxide are continuously removed via 4 to separators 12 for recycling of the oxide.ALSO:Phosphonic acids or salts thereof containing 2 P atoms in the molecule are obtained from mixtures formed by reaction of carboxy type acylating agents with phosphorous acid or by reaction of PCl3 with carboxylic acids, by treating the mixture with C1-C5 alkanols and (a) distilling off the volatile substances formed and, if desired, converting the acids into the salts, or (b) separating the alcoholic layer after addition of aqueous base.  The preferred alkanols are methanol and ethanol. Examples are given in which acetic acid, caproic acid, capric acid, palmitic acid, stearic acid and benzoic acid is reacted with PCl3 and in which acetic anhydride or acetyl chloride is reacted with phosphorous acid.  The products may be used in water-softening processes (see Division C1).

Title: Electronic timepiece
IPC: G04C17/00
Filed: 1974-11-28
Abstract: 1481679 Electronic timepieces CITIZEN WATCH CO Ltd 28 Nov 1974 [26 Dec 1973] 43914/76 Heading G3T In a battery powered electronic timepiece, when the battery voltage falls to a predetermined level a member is moved across a calendar window. In Fig. 3, an arm or lever 160 pivoted at 161 has an indicator member 164 and under normal conditions is held at one end in a recess 171 of a leaf-spring 170. Momentary energization of a coil 152 moves the lever so that one end enters a recess 172 where it remains when the coil is de-energized, and the indicator member appears in a window 180. The battery voltage is detected by a potentiometer 122, 123, Fig. 1, and an inverter 121 which produces a low level output when the voltage is normal. When the voltage drops to a predetermined level the inverter output goes high and the output of a NOR gate 144, in a single pulsegenerator circuit 104, becomes low so that charging of a capacitor 142 through a resistor 141 begins. At the same time the output of an inverter 143 goes to a high level so that a transistor 151 conducts energizing the coil 152 and the indicator member is displayed. When the capacitor has charged to a level whereat a point C reaches the threshold voltage of inverter 143, the output of the latter goes low and transistor 151 turns OFF. In an alternative embodiment Fig. 4 (not shown), the single pulse generator is omitted. Instead a contact on the arm 160 normally engages a contact connected to the coil which contacts disengage as the arm is moved upon energization of the coil and thereby de-energizes the coil.

Abstract: 1,273,310. Fluid-pressure servomotor systems. MOOG Inc. Sept. 16, 1970 [Oct. 6, 1969] No. 44199/70. Heading G3P. An output drive member 29, Fig. 1, may be driven in one direction by a first drive member 30 responsive to the pressure difference between a first chamber 32 and a sump 40 and in the opposite direction by a second drive member 31 responsive to the pressure difference between a second chamber 36 and the sump, the pressure in the sump being maintained at a predetermined value below the lower of the pressures in the first and second chambers by a pair of valves 70, 73. A spring 75 interposed between the valves maintains the sump at a level of 50 to 100 psi below the chambers 36, 38. If an electro-hydraulic valve 21 is operated to raise the pressure in chamber 32 and lower it in 36 reduced pressure on a plunger 74 communicating by way of a passage 79 with the chamber 36 allows the valve 73 to open. Fluid now flows from the sump into a line 82 until the sump pressure is 50 to 100 psi below the pressure in chamber 36 when the valve 73 closes. If the signal to valve 21 is reversed the valve 70 is operated and the direction of rotation of the member 29 revised. In Fig. 12, pistons 105, 109 connected to a lever 111 replace the members 29, 30, 31 while the pressure difference between the chambers 102, 103 and the sump 104 is maintained by a pair of spring-loaded valves 124, 128. In a further embodiment, the output member consists of a rotor (143), Fig. 13 (not shown) with sliding vanes (145) and the pressure difference between chambers (146, 148) and the sump (159) is maintained by a pair of differential pistons (166, 169). Mechanical backlash is eliminated in all of the embodiments described by the fluid-pressure preloading of the moving parts.
