Title: Coating process
Inventor: FERNSTROM GEORGE ARVID
IPC: D06M23/10
Filed: 1969-10-30
Abstract: 1285585 Coated yarns EI DU PONT DE NEMOURS & CO 30 Oct 1969 [31 Oct 1968] 53341/69 Heading B2E [Also in Division D1] An elongated flexible substrate is coated by advancing through a heating zone at greater than 500 yards per minute so as to heat it to at least 80C. but below the melting point of the substrate, applying an unheated liquid mixture comprising a polymeric coating material and an inert solvent of boiling point at least 80C. but below the melting point of the polymer to the advancing heated substrate, the speed and temperature of the substrate being sufficient to vapourise the solvent and dry the polymer material on the substrate in the form of an adherent coating of thickness less than one-fifth of the thickness of the substrate. The process is applicable to the sizing of yarns and filaments prior to weaving and knitting. The yarns may be composed of cotton, wool; polyesters, polyacrylics, and especially polycarbonamide. Examples of polycarbonamides are given. The coating mixture may be applied by roller, doctor knife, spraying and may comprise polyacrylic acid and a finish oil, e.g. a mineral oil or long chain fatty acid ester. In a typical example, polyhexamethylene adipamide is melt-spun through a spinnerette, an antistatic aqueous finish comprising polyethylene glycol di-2-ethylhexoate is applied, the yarn then passed to a pair of draw rolls heated to 190C. around which the yarn is wrapped, and then the heated yarn passed to a size applicator roll. The sizing mixture was prepared by adding 126 parts of a 25% aqueous polyacrylic acid solution to 400 parts of a stirred emulsion comprising 70.2 parts butyl stearate, 4.0 parts polyoxyethylene sorbitol hexaoleate, 8.3 parts fatty acid esters of higher polyglycols, 2.3 parts oleic acid, 7.5 parts long chain alkyl phosphate, and 1.7 parts potassium hydroxide added as a 45% solution in water, diluted with water to provide a 12% emulsion.

When indentations 6 of the insertion part 3 are in alignment with the pins 14 the device 13 returns to the position shown in Fig. 1. Release of the insertion part 3 is effected by manual pressure being applied to the releasing device 13 at 23, Fig. 2, so as to pivot the device 13 and allow the pins 14 to release the respective indentation 6 of the insertion part 3.  A lamp 28 is mounted at 29 on a casing 17 of the socket 1 and serves to indicate when the insertion part 3 is not within the socket or has been inserted beyond the position shown in Fig. 1. The lamp 28 is connected to an electricity supply via fixed contact elements 24b and 24c and a movable contact element 24a, the latter being urged by a leaf spring 26 towards the fixed contact element 24c and being moved away from the fixed contact element 24c by portion 4 of the inserted part 3.

Type-actions using auxiliary power.-A typelever 2 is swung to effect impression by a spring 14 through a pair of parallel links 12, 13, a striker bar 11 and a coupler 5, the power in the spring derived from a toggle mechanism 15, 16, 19 and a continuously rotating cam 20 which cocks the mechanism after the chosen coupler 5 has been actuated. The coupler 5 is actuated by a pawl 22 which releases a cam pawl 21, this in turn releases the coupler from a support 9 and recess 10, and the spring 14 moves the coupler 5 to the left and the type-lever 2 towards the platen. Impression is effected by momentum. A shift bar 24 is also actuated and this operates a latch mechanism, Fig. 2, (not shown), so. that the cam 20 is effective to operate the toggle mechanism and recock the spring 14. In a modification, Fig. 4 (not shown), the striker comprises a two-armed bridge (38) and the cocking of the toggle levers 15, 16 is dependent upon the release of a bell-crank lever (40), one arm of which comprises an armature (42) of an electromagnet 43.

Abstract: 1330350 Motor vehicles KLOCKNER. HUMBOLDT-DEUTZ AG 2 Dec 1970 [2 Dec 1969] 57272/70 Heading B7H [Also in Division G1] The efficiencies of engine transmission and wheel adhesion of a vehicle, e.g. an earth working vehicle, are all monitored and displayed, and the combination of all three giving a measure of overall efficiency is also determined. In the Fig. a reference 3 represents a fuel injection internal combustion engine. A signal representative of the fuel fed to the engine and hence the idealized torque thereof is derived from a logarithmic potentiometer 10 and fed on line 14 to a logarithmic adding circuit 15 to which a signal indicative of engine speed derived from a potentiometer 18 is also fed. The output from 15 which is a logarithmic representation of idealized input power is fed on line 77 to an engine efficiency computer 76. Logarithmic signals and components are used throughout the embodiment so that products such as power (torque x speed) may be obtained by addition. A measure of the torque at the engine end of the torque converter/gear change system 22, 23 is derived from a log potentiometer 29 and fed to a log adder circuit 31 together with the speed signal derived from circuit 18. The output from circuit 31 which is a measure of output engine power is fed on line 68 to the computer 76, whose output therefore is a measure of engine efficiency which is displayed at 82. A measure of the power at the output end of the gear system is derived from a circuit 50 whose input signals comprise a torque signal derived from a potentiometer 48 and a speed signal derived from a potentiometer 55. The output on line 69 is fed to a computer 70 where it is compared with the signal on line 68 to give a measure of transmission efficiency displayed at 75. The speed signal derived at 55 is a measure of the rotational speed of the driven wheel 45 and is compared with a signal from a tacho generator 61 which is attached to an idler wheel 60 and is representative of one slip rotation. This comparison is made in a third computer 57 whose output is a measure of wheel slip and is displaced at 66. Overall efficiency is displayed at 91.
