Title: Mixed normal salt of maleic acid and use as catalyst in resinous compositions
IPC: C07C57/145
Filed: 1962-03-28
Abstract: The invention comprises a mixed normal salt of maleic acid wherein one carboxyl group of the acid is neutralized with triethylamine and the other carboxyl group is neutralized with an amine selected from 2-dimethylamino-isobutanol, triethylenediamine, 1, 2-bis (dimethylamino)-ethane, 1-amino-3-dimethylamino-propane, and 1-dimethylamino-2-hydroxypropane.  The salts are prepared by reacting one mole of triethylamine with one mole of maleic acid and then adding one mole of the other amine, or the order of adding the amines may be reversed.  A solvent for maleic acid may be used if desired.ALSO:A composition for use in surface coating comprises a thermosetting aminoplast resin and a catalytic amount of a mixed normal salt of maleic acid wherein one carboxy group is neutralized with triethylamine and the other carboxy group is neutralized with 2-dimethylamino-isobutanol, triethylenediamine, 1,2-bis-(dimethylamino) ethane, 1-amino-3-dimethyl-amino-propane, or 1-dimethylamino-2-hydroxy-propane. The composition may contain 15% to 40% by weight of the aminoplast resin and 85% to 60% of a glyceride oil modified alkyd resin together with the mixed normal salt of maleic acid in catalytic amount.  The aminoplast resins may be alkylated, specified resins being melamine-formaldehyde and urea-formaldehyde resins.  The compositions may be used with or without an inert organic solvent or pigments. The resin composition may be used for moulding when it is mixed with a filler, e.g. alpha cellulose. Examples are given of the preparation of the aminoplast resins and of compositions made therefrom.ALSO:A surface coating composition comprises a thermosetting aminoplast resin and a catalytic quantity of a mixed normal salt of maleic acid wherein one carboxyl group of the acid is neutralized with triethylamine and the other carboxyl group is neutralized with 2-dimethylamino-isobutanol, triethylenediamine, 1,2-bis-(dimethylamino) ethane, 1-amino-3-dimethylamino-propane or 1-dimethylamino-2-hydroxypropane.

Abstract: 1500849 Measuring radiation absorption GERBER SCIENTIFIC INSTRUMENT CO 24 March 1976 [4 Aug 1975] 11830/76 Heading G1A [ Also in Division H4] A system for measuring absorption by a body includes a ray generator (52), Fig. 4 (not shown), and scanner 10, detector 14 producing a signal ED dependent on the intensity of the beam 12 after its passage through the body 16, control means 30 responsive to ED for varying the emitted intensity of beam 12 to maintain ED substantially constant means 32 for providing a signal corresponding to the emitted intensity of beam 12 and the transmissivity of body 16. The control signal E O  may be repetitively sampled by computer 34 and combined with position identifying information commanded on line 19. ED may be combined with reference signal (ER in circuit 26). The feedback circuit 30, (52), 16, 14 Fig. 6 (not shown) of amplifier 28 of gain A has a feedback coefficient B.AB#1 so that Eo = E R/B . Thus B is dependent solely on the transmissivity of the body. To obtain a different relationship between transmissivity and B a suitable network may be inserted before means 30. Intensity control may be means of a grid in or of the filament current of the X-ray tube (52) or by controlling its high voltage supply, a voltage divider across the output of which may supply the signal representing transmissivity to computer 34. The graphic display device 36 may be a C.R. Tube.

Abstract: 1444049 Mechanical switches SABASCHWARZWAELDER APPARATE - BAUANSTALT AUGUST SCHWER SOEHNE GmbH 19 March 1974 [4 May 1973] 12087/74 Heading H1N A retractive switch 1 can be actuated manually by a button (not shown) on the end of a push rod 11 or by a remotely controlled motor (not shown) which is geared to drive a cam plate 5 having a cam surface 6 to displace the movable contact 30 of a change-over set 29, 30, 31 for a predetermined operating phase of the motor, and said cam plate 5 having an eccentric crankpin 8 which engages an actuating member 9 mounted on the push rod 11 to displace it axially and thus actuate the switch 1, the motor being controlled by a thyristor in its circuit, and said change-over contact set ensuring that the motor is brought to maximum torque by connecting full supply voltage to it just before engagement between the crank-pin 8 and the actuating member 9. As shown the actuating member 9 is substantially rectangular and is coupled to push rod 11 by a spring 12 which is stronger than the internal restoring spring in switch 1 and allows for overtravel of member 9. The cam surface 6 extends over approximately 180 degrees so that the motor is maintained energized while push rod 11 moves to the right and back again. In its normal rest position contact 30 connects a thyristor (24, Fig. 4, not shown) in series with a resistor (25) and the motor (28) and also connects a resistor (27) in parallel with the motor such that, when the thyristor (24) is gated on, the motor runs at reduced voltage. When contact 30 moves to engage contact 31 it disconnects the parallel resistor (27) and replaces the thyristor (24) and series resistor (25) by a diode (26) thereby maintaining the motor at half-wave rectified full supply voltage.

Title: Improvements in or relating to gyroscopic navigational instruments
IPC: G01C19/38
Filed: 1941-09-19
Abstract: 565,802. Gyroscopic apparatus. SMITH & SONS (MOTOR ACCESSORIES), Ltd., S., and MEREDITH, F. W. Sept. 19, 1941, No. 12166. [Class 97 (iii)] A gyroscopic instrument which is so constructed that its indicator (a miniature aircraft) when at zero informs the pilot that he is on, or is returning to, his course, or informs him (if the indicator is off the zero) that he is off or leaving his course comprises an inclined rotor 18, Fig. 2, mounted in a fore- and-aft direction in gimbal casings 15, 13 for three degrees of freedom, erecting means for maintaining the rotor axis in the plane of symmetry of the aircraft and an indicator (miniature aircraft) which moves in a similar direction to the banking and turning movements of the aircraft. The rotor is driven by air supplied through the gimbal bearings. Relative movement between the inner and outer gimbals is indicated by the miniature aircraft 23 actuated by gearing 20, 21 and visible through a window 24 provided with an horizontal mark 25, Fig. 1. Thus rolling of the aircraft is indicated by tilting of the miniature relative to the mark 25, and climbs or dives by rising or falling of the miniature above or below the mark. In addition if the aircraft turns off its course about its yaw axis the miniature (owing to the inclination of the spin axis of the rotor) indicates as though the aircraft were proportionately banked. The pilot then brings the aircraft back by the usual controls until the miniature again coincides with the mark 25. The spin axis of the rotor is maintained at the correct angle by an erecting device 38 comprising an horizontal shutter and air jets arranged in the manner described in Specification 548,376. A second erecting device for restoring the spin axis to the plane of symmetry of the aircraft comprises an air jet issuing from the front trunnion 29 of the inner gimbal 15 and impinging against a knife-edge 27 on the outer gimbal 13. The air within the gimbal casing 13 besides issuing from the second erecting device passes out through a valve 31 in the fixed casing 10. If the pilot wishes to change his course, he closes this valve manually during the turn, thereby increasing the air issuing from the second erecting device and intensifying its action in precessing the spin axis to its new position. The action may be made automatic by replacing the valve by a shutter on the inner gimbal 15 to restrict the outward flow of air when banking exceeds a prescribed amount.

Abstract: In the oxidation of fatty oils or acids by oxidizing gases, the air, oxygen, or gas containing oxygen is pre-heated until the oil has reached a predetermined temperature.  In an example, air at 500 DEG C. is passed through linseed oil in a still until the temperature of the oil is about 200 DEG  C.; cold air is then passed through the oil for 8-12 hours, care being taken to keep the temperature of the oil below 280 DEG  C., and preferably at about 200 DEG  C.  Fatty acids in or formed in the oil are carried away by the excess of gas, and are condensed.  Linseed oil, fish oils, fatty acids, unsaturated fats, and any animal or vegetable drying oil are specified as suitable for treatment.
