Title: An improved knotter hook assembly for the knotter mechanism of a baling machine
IPC: A01F15/14
Filed: 1965-10-15
Abstract: 1,091,092. Knot-tying devices. INTERNATIONAL HARVESTER CO. Oct. 15, 1965 [Dec. 21, 1964], No. 43765/65. Heading D1C. A knot tying device for a baling machine has the jaw 23 so mounted that it is capable of a slight translatory movement as well as a pivotal movement about its pivot 34, Figs. 7 and 8, to enable it to accommodate twine of different thickness. For this purpose the jaw 23 has a slot 36 through which the pivot 34 passes to retain the jaw in a slot 33 of the hook. The hook is secured by its shank 43 in the rotary shaft 24 and accommodates a spring 38 which bears on the jaw 23 and urge it downwardly so that the upper-end of the slot is pressed against the pivot, Fig. 8. If thin twine is engaged it passes between the hook and jaw which has the slope 35 of the portion 40 bearing on the bridge portion 44 of the hook sudh that a lesser pull on the twine is required to release it compared with a heavier twine. In the latter case, Fig. 7, the twine causes the jaw to ride up to press the pivot against the lower end of the slot and simultaneously alter the angle of the slop 35 relative to the twine such that a stronger pull is now required to release it from the jaw and hook.

Patent GB-1027059-A (GB)
Title: Process for the manufacture of aminoaryl phosphates and phosphonates
IPC: C07F9/12
Filed: 1964-10-30
Abstract: Phosphoric acid esters or phosphonic acid esters containing at least one aminoaryloxy group linked to phosphorus are prepared by reacting, at an elevated temperature, a phosphoric acid ester or phosphonic acid ester containing at least one aryloxy group linked to phosphorus with an aminophenol, in the presence of an alkali metal hydride and transesterification catalyst.  The preferred alkali metal hydride is sodium hydride suitably in the form of a dispersion in mineral oil, and the reaction is preferably carried out at a temperature between 120 DEG  and 200 DEG  C., under anhydrous conditions and in the presence of an inert gas such as nitrogen.  Advantageously, the reactants are chosen so that the aminophenol used is less volatile than the phenol eliminated during the transesterification.  Preferred use is made of triaryl phosphates of the Formula (I) O = P(OR)3 or an aryl phosphate of the Formula (II) <FORM:1027059/C2/1> where the radicals R are identical or different aryl radicals and Z stands for a divalent aromatic mononuclear or polynuclear radical such as <FORM:1027059/C2/2> The amino groups in the aminophenol may be tertiary, secondary or primary and the aminophenol may be substituted in the benzene ring by such groups as alkyl groups and chlorine atoms.  For the preparation of mixed phosphoric or phosphonic acid esters derived partially from aminophenols and partially from higher mononuclear or polynuclear, monohydric or polyhydric phenols the process is modified by including in the reaction mixture a less volatile phenol, followed by elimination of the more volatile phenol. The mixed esters may also be prepared by a two-stage process in which in the first stage, for example, a triaryl phosphate is partially transesterified with a higher phenol and in the second stage transesterification with the aminophenol is effected. Alternatively the reverse order may be used. The aminoaryl phosphates and phosphonates may be used as curing agents for powder coatings, choline esterase inhibitors, intermediates for the manufacture of isocyanates and dyestuffs as cross-linking agents for curable synthetic resins.  The intermediate compound <FORM:1027059/C2/3> is described as being prepared by the reaction of 2,2-bis(4-hydroxyphenyl)propane with triphenyl phosphate in the presence of sodium hydride as catalyst.

The input race 64 of a steplessly-variable toric race friction gear, having a single set of tiltable non-planetary rollers 103, is driven from the input shaft 58 through a non-variable toothed or friction gear 56, which changes the input speed in sign and magnitude, whilst its output toric race 69 forms one input of a second non-variable torque-splitting planetary gear 72, having a final output element 53 and a second input element 79, driven by the input toric race 64 through an intermediate shaft 65. The overall range of the gear, used on a motor vehicle, provides output at reduced reverse; a geared neutral with the two inputs to the second non- variable gear cancelling each other; and reduced and overdrive forward ratios. There is also a positive neutral, parklock, and common hydraulic end loading for traction pressure. In Fig. 1, the input toric race 64 is driven at increased reverse speed through toothed wheels 61 in a permanently fixed carrier 60, and meshing external teeth 63 in input toric race 64 and internal teeth 57 in a ring gear fast with the input shaft 58. The non-variable output gear 72 comprises planetary balls 74 in an output carrier 75, contacting the back of the output toric race 69 and an assembly 79 splined to the intermediate shaft 65 to which is also splined the input toric race 71, the assembly 79 enclosing a dowelled piston 82 for hydraulic end-loading contained within abutments 65a, 68 on the intermediate shaft 65. A spring 87 in the assembly 79 provides initial end-loading for a push start. A clutch sleeve 78, splined to the final output member 53 clutches the ball-carrier 75 for reverse, geared neutral, and forward drives; releases it for positive neutral, and clutches casing teeth 91 for parklock.
