Title: Electrodepositable amino plast resins
Inventor: MARSH JOHN FREDERICK
IPC: C08G12/04
Filed: 1967-01-13
Abstract: An aminoplast resin is prepared by reacting urea with formaldehyde and an a -amino acid in a primary alcohol or ether alcohol medium; the preferred molar ratios of urea : formaldehyde : alcohol : amino acid are 1 : 2-3 : 2-3 : 0.025-0.4. The formaldehyde may be used in the form of paraldehyde, or, preferably as a 36 w/v per cent aqueous solution.  Suitable alcohols are n-butanol or 2-butoxyethanol or a n-butanol/n-pentanol mixture.  Suitable amino acids are glycine and alanine.  All four ingredients may be heated together at 30-140 DEG C. to give the resin or, preferably, the urea, formaldehyde and alcohol, adjusted with aqueous ammonia to pH 7-9, may be heated until the mixture becomes acid, when the amino acid is added.  Finally, excess solvent is removed to give a viscous resin containing, e.g. 70% solids.  This may be washed while acid, before neutralizing, e.g. with ammonia or an amine (NR3 where each R is -CH3, -C2H5, -C2H4OH or H) and diluting with water, e.g. to 10% solids.  The aqueous neutralized resin may be applied to metals by electrodeposition, dipping, or spraying and cured at, e.g. 130-180 DEG  C. The coating composition may also contain a water-soluble alkyd or acrylic resin and/or pigments and/or small amounts of organic solvents, e.g. n-pentanol, isopropanol, or 2-butoxyethanol.  In examples, resins are prepared from urea, formaldehyde, n-butanol and glycine by both the above methods, and are neutralized with conc.  NH3 solution; 10% aqueous solutions of the resin alone or mixed with a water-soluble acrylic resin providing 75 wt. per cent of the total resin are used to coat steel panels by electrodeposition.ALSO:Metallic substrates are electro-coated from an aqueous composition comprising the neutralized product of the reaction of urea with formaldehyde and an a -amino acid in a primary alcohol or ether alcohol, the preferred molar proportions of urea: formaldehyde: amino acid being 1:2-3:0.025-0.4 in 2-3 moles of alcohol.  (see Division C3).  The coating composition may also contain a water-soluble alkyd or acrylic resin and/or pigments and/or small amounts of organic solvents.  In examples resins are prepared from urea, formaldehyde, glycine and n-butanol, neutralized with NH3, diluted to 10% solids with water, and used alone or mixed with an acrylic resin to coat steel panels by electro-deposition.  The abraded and degreased 4" x 2" panels are immersed to 2" in the bath 1" apart and coated at 10 or 30 volts D. C.; the coated panels are stoved at 150 DEG C. for 30 mins.

Title: Speed governors for fuel injection pumps
IPC: F02D1/10
Filed: 1975-01-17
Abstract: 1486111 Speed governors ROBERT BOSCH GmbH 17 Jan 1975 [18 Jan 1974] 2055/75 Heading G3B A speed governor for fuel injection pumps of internal combustion engines comprises a first lever 18 which is pivotal about a spindle 19 and which is adapted to be connected at one end to a fuel delivery adjusting member 16 and pivotally secured at the other end 23 to a second lever 25 acted upon by a starting spring 46, a centrifugal governor 40 which acts on lever 25 against a main regulating spring 32, a capsule 49 at one end of lever 25  which co-operates with a further lever 27 acted  upon by spring 32 and which is pivotable about spindle 19 up to an adjustable stop 35, lever 25 having a stop 37, which projects towards lever 27, and is located between the centrifugal governor and the pivot 24. In operation, with lever 27 abutting stop 35 under the action of spring 32, with lever 25 pressed against sleeve 39 of governor 40 by the action of spring 46 and with lever 18 moved away from lever 27, valve-member 16 is in its uppermost starting position. The engine is started and governor sleeve 39 compresses starting spring 46 and moves lever 25 towards lever 27 until stop 37 engages lever 27, at which point valve-member 16 has been displaced downwardly by lever 18 to reduce the quantity of fuel injected. The excess starting quantity is shut off at this instant. Upon a further increase in speed, spring 52 is compressed so as to pivot lever 25 about its stop 27 until head 53 enters capsule 49 and the latter abuts lever 27, whereupon lever 18 is pivoted and member 16 is displaced upwardly to increase the fuel supply. Further movement of governor sleeve 39 moves lever 27 away from stop 35 against the force of spring 32 and due to the movement of all levers member 16 is again displaced downwardly to reduce full flow. Spring 46 can be replaced by a spring initially stressed between the housing of the device and lever 25.

Abstract: 655,060. Refrigerating; freezing fish etc.; heating granular materials. BARRIS, P. G. M. Jan. 23, 1948, No. 2145. Convention date, Feb. 10, 1947. [Classes 29 and 64(ii)] Frozen particles to be used in preserving foodstuffs as described in Specification 655,061 are formed by injecting a fine spray of gas or liquid into a fast-moving stream of cold fluid such as air so as to freeze instantaneously the spray into particles of about one micron in diameter and having a temperature of about -200‹C, the particles being then deposited on the foodstuffs. Air is compressed by a compressor 16, cooled in a heat exchanger 1, does work in a turbine 2 and mixes with the spray of gas or liquid entering by a pipe 4. The particles are electrically charged and are deposited on the foodstuffs in a chamber 5, the air then returning to the compressor 16 by way of a compressor 8 driven by the turbine 2 and the heat exchanger 1. Any particles carried through chamber 5 are collected in a chamber 7 and perform cooling in exchanger 17. In starting up, the air stream byepasses the chamber 5 through a pipe 10 controlled by valves 11, 12. The spray entering by the pipe 4 may be water, syrup, brine or carbon dioxide, the temperature and velocity of the air stream at this point being of the order of -200‹C and 200 metres per second respectively. The turbine 2 also drives a dynamo 15. Heating granular materials. The Specification also refers to a method of obtaining heated particles of e.g. metal powder of high specific heat comprising introducing the particles into a stream of dried gas having a velocity of about 200 metres per second and being hot enough to heat the particles to the required temperatures instantaneously.

Abstract: 1,179,381. Rotary I.C. engines. P.R. MALLORY & CO. Inc. Jan.15, 1968 [Jan.16, 1967], No.2162/68. Heading F1F. A rotary I.C. engine has an air-cooled casing 11 containing rotors 16a, 16b with slidable vanes 46 between sealing means 21, contact between the vanes and the inner wall 13 of the casing being prevented by flanges 49, 49' on each vane engaging with pivoted connecting-rods 58 on a ring 57 supported by a bearing 59 upon the pin 30 of a fixed crank-shaft 29. The plate 22 is attached to a power-output shaft 38, which drives a blower 98 for supplying air to a section 15b of a working chamber 15. After compression by the rotor 16b the air is transferred to a second section 15a of the chamber 15 through passages 36, 36' and a duct 35 receiving fuel from a nozzle 37. A sparkplug 60 ignites the fuel initially, hot gases travelling along grooves 62 sustaining ignition thereafter. The mixture of fuel and air is slightly decompressed upon entry to the section 15a before ignition. Exhaust gases escape through a duct 64. Synchronization of the rings 57 with the rotors is effected by teeth 39 on the latter meshing with notches 40. An oil reservoir 69 is connected to the interior of the engine through a pump and passages (not shown) in the pin 30.

Title: Improvements in and Relating to Transducers
Filed: 1967-01-16
Abstract: 1,148,643. Measuring linear displacement, electrically. KAMAN AIRCRAFT CORP. Jan.16, 1967 [Jan.27, 1966], No.2175/67. Addition to 1, 055, 354. Heading G1N. Relates to a modification of the displacement transducer described in parent Specification 1, 055, 354 and comprises a pair of secondary coils 108, 110 Fig. 1 and a primary coil 106 and a non-magnetic electrically conductive slug 102 movable relative thereto. The slug may comprise a metallic sleeve e.g. aluminium on a ceramic core or may be solid metal or may comprise a plurality of metal sleeves on a ceramic core Fig.6 (not shown). The secondary coils may be differentially connected so that a zero output is obtained therefrom when the slug is centrally disposed between them Fig. 3. Movement of the slug away from the null position increases the losses in one secondary coil due to eddy currents in the slug, and decreases losses in the other thereby producing an output voltage the phase of which, with respect to the primary voltage, is dependent upon the direction the slug is moved and the magnitude of which is dependent on position. A peaking capacitor 116 may be connected across the primary to produce resonance at the operating frequency. In an embodiment Fig.4 (not shown) the secondary windings are connected in series, the common junction being connected to one output terminal. The other ends of the secondaries are connected respectively through load resistors and rectifying diodes to another output terminal. A D.C. output is thereby provided having a magnitude and sign dependent upon the amount and direction of movement respectively of the slug.

Abstract: 830,720. Two-part couplings combined with switches. HUBBELL Inc., H. Jan. 23, 1958, No. 2298/58. Class 38 (1). A plug and socket coupling for industrial use has the resilient spring-pressed socket contacts 50 (Fig. 7) guarded by a shutter disc 65 slidable in the insulating socket body 40 against spring 67, the disc 65 being locked by nylon pins 73 (Fig. 5) which are released when the member 75 or 80 in the plug part pushes down sleevelike cam member 70 during insertion of the plug. Contacts 6, 7, 8, &c., which may be moulded into the plug enter vertical slots in socket 40, wrong engagement being prevented by making earth contact 8 larger than the others. When sufficiently inserted the plug is turned so that the upper shoulders of the plug contacts go under steps 48 in the slots. On withdrawal of the plug the disc 65 returns to its closing position against shoulders at the top of the socket bore and pins 73 return to the locking position. Energization of socket contacts 50 may be effected only when the plug is introduced into the socket by an electromagnetically controlled switching unit 82 operated when entry of the plug closes switch 95. The switching unit 82 may be enclosed in a separate housing remote from the socket. Moisture &c. is excluded from the plug by a soft rubber sealing pad.

Title: Means for producing low frequency modulation of a higher frequency current

Filed: 1950-01-30
Abstract: 667,813. Inductive control systems. SVENSKA AKTIEBOLAGET GASACCUMULATOR. Jan. 30, 1950 [Jan. 31, 1949], No. 2363/49. Class 38 (iv). Apparatus for producing low-frequency modulation of a higher frequency current comprises a self-magnetized transductor connected to an A.C. source, and two control circuits influencing the reactance of the transductor in opposite senses, one of the control circuits comprising resistors only, the other control circuit comprising inductors only. A lamp in a flashing sign forming the load 16 is fed from an alternating current source by way of two selfmagnetizing windings 4, 5 on a transductor 1 and two half-wave rectifiers 10, 11 poled so that the windings 4, 5 conduct alternate half-cycles of the supply current. A rectifying bridge 12 in parallel with the lamp 16 feeds two parallel circuits, the first comprising transductor windings 6, 7 and variable resistors 19, 14, the second comprising transductor windings 8, 9 and an inductance 13. The direction of magnetization of windings 6, 7 assists that of windings 4, 5 whilst that of the windings 8, 9 opposes that of the windings 4, 5. The added magnetizations of windings 4, 5 and 6, 7 saturates the transductor thereby lowering its reactance so that the major portion of the supply voltage is available across the lamp 16 thus lighting it. The opposing magnetization of the windings 8, 9 is delayed in growth by the presence of the inductance 13 such that it slowly increases to a maximum value and then decreases therefrom. The reactance of the transductor thus increases and decreases so that the lamp 16 is lit up at regular intervals, the light and dark periods being controllable by means of the adjustable resistors 19, 14. In other embodiments the rectifying bridge may be arranged in parallel with the transductor instead of with the lamp; again the transductor windings 8, 9 may be dispensed with, the rectifying bridge in this case feeding an impedance bridge so that the opposing magnetization of the transductor are produced by the same windings. In yet another embodiment the rectifying bridge is placed in series with the windings 4, 5, and is arranged to feed two parallel circuits, one of a nature similar to that of the first in the embodiment according to Fig. 1, the other containing only an inductance similar to the inductance 13.
