Title: A method of reducing friction and a lubricant for use therein
Filed: 1957-09-20
Abstract: A fluid lubricant, suitable for reducing friction between contacting solid surfaces at temperatures in excess of 550 DEG F., comprises at least 60% by weight of a dialiphatic ester of a dimer of hydrogenated dimer of one or more ethylenic monocarboxylic acids, at least one of the acids being a polyethylenic acid, each aliphatic group having 1-10 carbon atoms and each acid having 12-22 carbon atoms.  Specific esters mentioned are dimethyl, diethyl, dibutyl or di (2-ethyl-hexyl) dilinoleate, the dipropyl ester of the dimer of 5,9-dimethyl-2,8-decadienoic acid, the dihexyl ester of the dimer of linolenic acid, the didecyl ester of the dimer of 13,15-docosodienoic acid, and the dibutyl ester of the codimer of oleic and linoleic acids.  The lubricant may also contain an antioxidant (e.g. phenothiazine or a blend of phenyl-beta-naphthylamine, p-isopropoxy-diphenylamine and N,N1-diphenyl-p-phenylene diamine), an extreme pressure of anti-wear additive (e.g. 2,21-dichloro-diphenyl) phenyl phosphate, di (o-chlorophenyl) phenyl phosphate, trialkyl esters of phosphoric acid, mixtures of mono- and di-alkyl esters of phosphoric acid, and rhodanine), and viscosity index improvers or pour point depressors (e.g. polymers or copolymers of alkyl esters of methacrylic acid).  In the examples, lubricating compositions are described consisting of the dibutyl ester of the dimer of linoleic acid (a) phenothiazine and di (o-chloro-phenyl) phenyl phosphate, (b) phenyl-beta-naphthylamine, p-isopropoxy-diphenylamine and N,N1-diphenyl-p-phenylene diamine with or without di (2-ethyl-hexyl) sebacate or (c) di (2-ethylhexyl) azelate, di (2-ethyl-hexyl) sebacate, butyl methacrylate polymer and phenothiazine.  For comparison purposes, a composition similar to (c) without the dibutyl dilinoleate is described.

Title: Process for the regeneration of spent activated carbon
IPC: C01B31/08
Filed: 1970-06-18
Abstract: 1311014 Regenerating absorbents; active carbon; purifying liquids DEGREMONT SOC GENERALE D'EPURATION ET D'ASSAINISSEMENT 18 June 1970 [20 June 1969] 29632/70 Headings C1A and C1C Spent absorbents, e.g. active carbons, are regenerated, by being first contacted with an alkaline solution at a temperature of 20 to 130 C. for a period of 30 mins. to 2 hrs. under conditions of almost stationary solution flow, followed by an aqueous solution containing at least one organic solvent at an increased flow velocity, removing this solvent from the carbon by injecting a hot fluid, e.g. steam, hot water under pressure, or hot air, and acid washing the so treated absorbent to give the regenerated material. The alkaline solution may be an aqueous solution of KOH, NaOH and NH 4 OH, e.g. an aqueous solution containing 0À5 to 25% by wt. NaOH. The organic solvent may be methanol, ethanol, propanol or butanol and is preferably an aqueous solution containing 20-75% by volume of isopropanol. The aqueous solution of organic solvent is preferably used at its boiling temp. under the pressure and temp. conditions obtaining in the treatment zone. The velocity of flow during the alkaline treatment preferably does not exceed 1 m./h., whilst the treatment with the aqueous organic solvent may be as fast as 10 m./hour. If desired the same aqueous alkaline/alcoholic solution may be used for the first and second stages of the treatment, merely the velocity of flow being appropriately adjusted, being for example five times faster than during the alkaline treatment. The acid used in the acid washing step may be HC1, H 2 SO 4 , H 3 PO 4 , acetic or formic acid. The active carbon may have a specific surface area in the range 500-1500 m.<SP>2</SP>/gm. The organic material abstracted by the organic solvent may be recovered by distillation. The other absorbents mentioned but not exemplified are molecular sieves and ion exchange resins. The examples illustrate the use of the absorbent of the present invention in the treatment of sugar solutions, waste water from a dye factory, solutions containing chlorophenol and detergents, and waste water from a chemical factory. The description suggests that the process is suitable for regenerating absorbants used for purifying drinking water, and for treating glycerine liquors from the soap industry.

Abstract: 1,119,245. Coin-freed apparatus. MICROTHERM Ltd. 15 Aug., 1966 [13 July, 1965], No. 29648/65. Heading G4V. A coin-freed vending machine for delivering an article to an externally accessible point is combined with a microwave oven for heating the article, said oven having a door which is released by insertion of a coin in the vending machine and re-locked on completion of a heating cycle. The oven door 18 moves in slides 20, 21 and is locked in its closed position by a solenoid-operated latch 24, 25. The door is closed automatically by an L-shaped arm 26 pivoted at 27. The arm carries a spring- loaded rod 45 engageable with the top of the door. The arm is spring-urged to follow a cam 35 on the output shaft of motor 33. A second cam 41 on said shaft controls a micro-switch 43. In operation, insertion of a coin in the vending machine releases the latch 24, 25 so that an article may be placed in the oven. On removal of a cooked article from the oven, a switch is closed to complete the circuit of motor 33. The arm 26 pivots to close the door and then returns to its initial position. The motor is de-energized when switch 43 is actuated. If the door meets an obstruction during closing, the rod 45 moves relative to the arm 26 to operate a switch 52 in the motor circuit. In a modification, the oven door 76 is moved between its open and closed positions by an arm 85 attached to a disc 83. The latter is rotated by a coin-freed mechanism. The arm 85 is made in two parts so that if the door meets an obstruction it yields axially to operate a switch (not shown) and stop the motor.

Abstract: 1,129,641. Ejectors; steam turbine plant. ISCOT MACHINES (SALES) Ltd. Oct. 27, 1965 [July 27, 1964; Oct. 23, 1964; Dec. 4, 1964], Nos. 29930/64, 43329/64 and 49527/64. Headings F1E and F1T. An ejector comprises a pipe (1), Fig. 1 (not shown), connected to a pressure fluid source, communicating with an aperture in a plate 2 and a flat plate 3 secured at such a distance in front of the aperture that an area of vacuum is created between the aperture and the plate when fluid passes through the pipe. The ejectors may be arranged in series or in other embodiments may be arranged as follows: - Fig.2: Air or other pressure fluid is admitted to jet tube 6 from reservoir 7 and impinges on plate 13. A vacuum is created in the gap between orifice 8 and plate 13, fluid is drawn through suction pipe 14 and the mixed fluids pass through chamber 15 and exhaust pipe or to the suction pipe 14 of a further injector. Fig.4: Air or water from a reservoir (e.g. reservoir 7 in Fig. 2) emerging from jet orifice 19 impinges on the end of a rod 30. The vacuum created draws in fluid through both suction conduits 25, 31. Rod 30 may be replaced by a hollow tube sealed at its free end. Fig. 5: In a liquid pumping application the passage of pressure air along passage pipe 120 and through the gap between plates 122, 124 exhausts air from a demijohn through branch 114 so that liquid is drawn through pipe 128 into the demijohn.

Title: Electric power supply installation
IPC: H02P9/30
Filed: 1962-08-03
Abstract: 951,367. Automatic control of current and voltage. BETEILIGUNGS-UND PATENTVERWALTUNGSGESELLSCHAFT m.b.H. Aug. 3, 1962 [Aug. 9,1961], No. 30031/62. Heading G3R. A load 1 is supplied from a D. C. generator 3 having a field winding 4 fed with pulsating direct current derived from the generator 3 by way of slip rings 6, a transformer 7, an air-gap choke 8 and a rectifier 5. A controlled rectifier 11 connected across the field winding 4 is responsive to a control voltage which is the difference between a reference voltage, derived from a Zener diode 15, and the voltage across a resistor 17 carrying the load current. When the load current is below a predetermined value at which it is to be maintained constant, the control voltage is not sufficient to make the rectifier 11 conductive, and the generator is fully energized; however, when the current reaches the predetermined value, the increased control voltage causes rectifier 11 to conduct, and the field winding 4 is effectively short-circuited whereby the generator output falls. With a decreasing load current, the control voltage decreases and the rectifier 11 then reverts to its non-conductive state when the pulsating direct voltage of the rectifier 5 passes through the zero value. This cycling action continues to maintain the load current at a constant value. The currentdependent voltage may be derived from a choke with a biasing winding (Fig. 2, not shown). The supply source may be an A. C. generator (Fig.3, not shown). In a modification, Fig. 4, both the output voltage and the load current are kept constant; the conduction of rectifier 11 is controlled by a current dependent voltage derived from a choke 27, 28 a rectifier 25 and a resistor 24, and the conduction of a further rectifier 45 is controlled by a voltage proportional to the output voltage at the circuit points 12,16 and derived from a voltage divider 40,41. The arrangement is such that either the rectifier 11 or the rectifier 45 is rendered conductive when the load current or output voltage exceeds the respective predetermined value. A single controlled rectifier with associated diodes may replace the rectifiers 11 and 45, and the circuit for derivihg the currentdependent voltage may include a transistor (Figs. 5 and 6, not shown). The supply source may be an A. C. network (Fig. 9, not shown), in which case the A. C. load current is maintained constant by controlling the biasing current of a choke in the supply line.

Title: Improvements relating to hydraulically actuated speed governors
IPC: G05D13/00
Filed: 1948-11-18
Abstract: 666,991. Fluid-pressure servomotor-control systems. MASSEY MACHINE CO. Nov. 18, 1948, No. 30039/48. Class 135. In an engine speed governor the engine rotates through a shaft 10 a ported sleeve 15 containing a piston valve 17, fly-weights 20 being pivoted to the sleeve at 22 and having a toggle connection to the valve at 24 so that on an increase in speed the piston is moved downwards against the centralizing spring 55 and the speed-setting spring 60. Pressure fluid from the pump 25 driven from the shaft 10 is supplied via the accumulator 29 to a port 32, and operates the piston 42 via passages 37, 38 and ports 39, 40, controlled by the lands on the valve and exhaust ports 52, 53. The engine shaft also drives at a different speed the rotary valve 90, angularly ported at 91, 92 so that on opening of the ports 39, 40 by the piston valve pressure fluid passes to the cylinder in spurts as the rotating ports in the sleeve and rotary valve come into line. The speed setting through the spring 60 is adjusted from the gear 73 acting through a rack 71 and differential gear 69 pivoted on the sliding rod 63. Movement of the piston adjusts a throttle or fuel control means through the crank 12, and readjusts the piston valve through the lever 80, rack 70 and differential gear 69, the lever fulcrum 84 being adjustable to control the speed droop. In a modification, the piston valve is balanced for lateral pressures by the provision of a stationary sleeve between the rotating sleeve and the housing 14 and the formation of annular grooves in both sleeves. In a further modification, supply passages to the cylinder bye-pass the rotary valve 90 and are connected to ports in the piston valve which are only uncovered when the valve is moved by the application of a sudden load producing a large speed variation, the opening of these ports increasing the number of spurts of pressure fluid. The "rapidity" characteristic of the governor is controlled manually by the opening of the rotary valve 98.
