Title: Carburettor

Filed: 1975-10-27
Abstract: 1484107 Fast-idle arrangement in IC engine carburetter FORD MOTOR CO 27 Oct 1975 [23 Dec 1974] 44008/75 Heading F1H In a carburetter having a throttle valve 36 whose idling position is limited by a gravity rotated fastidle cam 100 which is conjointly controlled by air flowing past an unbalanced choke valve 32 and a temperature dependent opposing force developed by a bi-metallic spring 68, at low engine temperatures, when.the bi-metallic spring force is weak and the air rushing into the carburetter may suddenly open the choke valve 32, the cam 100 is prevented from rotating too far, causing stalling on return of the throttle valve 36 to a hot-idling position, by an abutment pin 130 which co-operates with a detent in the form of a second bi-metallic spring 134. At higher temperatures the detent 134 is retracted allowing the cam 100 to fall on its shaft 76 to a hot-idling position. The carburetter includes a vacuum servomotor 84 to crack open the choke valve immediately after starting. The bi-metallic spring 68 is heated by engine coolant in a chamber 63 and additionally by a PTC semi-conductor heater 150 to open the choke valve 32 quickly during warm-up. The heater 150 also heats the second bi-metallic spring 134. The bi-metallic spring 68 rotates the fast-idle cam 100 by a shaft 70 and bell-crank lever 74. This lever 74 is biased to rotate either clockwise or anti-clockwise in dependence of temperature by a pivoting tension spring 92 overcentre arrangement and thus at low temperature tends to close the choke valve 32 while at high temperature tends to open it.

[Also in Division C3] Cured enamel coatings are formed on a metal surface, e.g. of automobiles, by applying to the surface, by spraying, a coating of an enamel pigment and, in solution in an organic solvent, a binder which consists essentially of an aminoplast resin and a copolymer of an acrylic or methacrylic ester, the copolymer having an acid value of 2 to 12, a glass transition temperature of 20-85C and an alcoholic hydroxyl content of 1.15-3%, based on the weight of the copolymer, 100 parts by weight of the combined aminoplast and copolymer content conraining 20-40 parts of the aminoplast and 80-60 parts of the copolymer; heating the coated surface at a temperature of 150- 230F for a time sufficient to obtain a Sward hardness of at least 9 while still in the thermoplastic state; sanding the coating to remove surface imperfections; and then heating the surface at a temperature above 230F for a time sufficient for the coating to reflow over the sanded portions and to cure the coating to the thermoset stage. The acid component of the copolymer may be an ethylenically unsaturated monocarboxylic acid or a monoalkyl ester of an ethylenically unsaturated dicarboxylic acid; alternatively, the acidity can be introduced by adding an acidic curing catalyst, e.g. p-toluene sulphonic acid or butyl acid phosphate, to the copolymer. The alcoholic content of the copolymer is derived from a hydroxy-containing monomer component such as an ethylenically unsaturated alcohol or a hydroxyalkyl ester of an ethylenically unsaturated carboxylic acid. The copolymer may also contain an additional monomer component, e.g. styrene, an alkyl styrene, acrylonitrile or vinyl pyrrolidone. As the aminoplast component, there may be used a condensation product of urea, thiourea, other substituted ureas, melamine, benzoguanamine, acetoguanamine or other triazine with an aldehyde, e.g. formaldehyde, the product being alkylated with an alkanol. Suitable solvents include aromatic hydrocarbons, alcohols, esters, ethers, ketones and mixtures thereof. Pigments specified are titanium dioxide, non- leafing aluminium, yellow and red iron oxides, umber, sienna, carbon black, lamp black and various organic pigments. An inert filler can also be used, e.g. silica, talc, china clay and sulphates. In Examples, coatings are formed on steel panels.

With the gate of 228 connected to its drain the circuit provides linear amplification while keyswitch 222 is closed provided to input signals remains within indicated limits. To provide a suitable decoy envelope the gate of 229 is connected to a capacitor 224 which discharges through an impedance 225 when keyswitch 222 is opened; as the gate voltage of 229 falls it runs into its constant current region giving the output waveform a flat top (Fig. 7, not shown), i.e. reducing the upper harmonics as the signal decays as in a conventional instrument; to further modify the response the impedance may be variable under the control of a voltage 226. If the gate of 228 is connected to a lower voltage the upper harmonics may be attenuated also when switch 222 is closed giving a different tone output. The voltage on the gate of 228 may also be modulated to provide vibrato. It is intended that the keying circuit 233 as well as the associated sawtooth wave frequency divider (not described in this Specification) be integrated on a single MOS chip; various embodiments of the variable impedance element 225 are described (Figs. 9-14, not shown) which essentially comprise as MOSFET with its gate and drain connected and having a resistive source region in which a variable voltage gradient is produced by the control voltage 226.

Abstract: A fabric elastic in the directions of both its warp and weft, e.g. a nylon knit, is bonded to a sheet of cellular rubber by a method comprising coating a preferably slit or scraped face of the cellular rubber with a rubber solution, allowing the solvent to evaporate, applying said fabric to the thus coated surface and pressing, optionally at an elevated temperature, to soften the coating and effect a permanent bond.  The method may be employed in the manufacture of insulating garments whereby a garment made of a material elastic in the directions of both warp and weft, and which may be laid flat without creasing, is covered on each side with a cellular rubber sheet coated as above, and bonded thereto by hot pressing to obtain the arrangement of Fig. 2, not shown, where the back portion adheres only to sheet 1a and the front portion to sheet 1b, and where beyond the marginal folds of the garment 2 the sheets 1a and 1b are bonded directly to each other. To obtain the finished garment the bonded assembly is cut out around line 3 (Figs. 1 and 2). Optionally, the outer surfaces of the sheets of rubber may also be covered with the fabric.
