Title: Improved mounting mechanism for coupling implements to tractors
IPC: A01B59/06
Filed: 1957-10-14
Abstract: 871,522. Tractor power-lift mechanisms. MASSEY-FERGUSON Inc. Oct. 14, 1957 [Oct. 17, 1956], No. 31965/57. Class 79(1). A mechanism for coupling an agricultural implement to a tractor has laterally spaced draft links 11, 12 connected by means (such as a flexible cable 47) to a power lift whereby the implement will rise and fall with the links by the operation of the power lift but will be permitted to tilt laterally relatively to the tractor independently of such operation. The means 47 consists of a cable which is connected by shackles 49 to the links 11, 12 and passes over pulleys 45 held between a pair of lift arms 16, 17 by a support member 38 secured by an axially spring-loaded shaft 41. The arms 11, 12 are secured to a shaft 14 connected to a manually or automatically controlled hydraulic ram. A transverse bar 26 forming part of the implement, which may be a multiple row planter, is connected by brackets 31 to the links 11, 12 and by a strut 32 to a link 13 while a pair of heavy gauge wheels 36 carried at opposite ends of the bar by arms 35 secured to a shaft 34 to swing vertically as a unit maintain the implement parallel to the ground, the cable 47 accommodating the relative movement between the links 11, 12. When the implement is raised to transport position, the arms 16, 17 swing upwardly raising the links 11, 12 through the cable 47 until a bottom facing on each lift arm engages a block 58 on a corresponding lever 56 connected by a universal coupling and a link 67 to the corresponding link 11 or 12. The implement is thus brought into parallel relationship with the tractor and the load on the cable 47 is relieved. Each lever 56 may be locked to its lift arm 16 or 17 by a lever pivoted at 61 to the lift arm and having a pin 66 to engage a slot 64 in a link 62 pivoted at 63 to the lever 56. In operation, the pin 66 and block 58 also serve to limit the movement of lever 56.

Filed: 1947-12-04
Abstract: 633,214. Testing dynamo-electric machines. SOC. D'EXPLOITATION DE BREVETS. Dec. 4, 1947, No. 32070. Convention date, Sept. 12,-1945. [Class 37] A generator testing plant comprises the generator D to be tested, a constant-speed driving motor M, a mechanical speed varying device V for rotating the generator D at selected speeds, and an auxiliary motor C, the armature of which is directly coupled with the armature of the driving motor M to rotate at a constant speed, the motor C being fed by the current supplied by the generator D. Switches F, H are opened and the driving motor M is started, the speed varying device V being adjusted until the required voltage is generated. This is measured by a voltmeter U which can be connected by a switch E to contacts el, e2, e3, e4 for measuring the voltage across the auxiliary motor C, the field winding of the generator D, the brushes of the generator D, and the mains t. The retracting spring of the contacts 4 of a make-and-break device Q is then adjusted so that closure takes place at this value of the generator voltage. The D.C. auxiliary motor C acts as a generator and its voltage is regulated by a rheostat Rh to the predetermined value of breaking of the device Q. The switch F is then closed and the generator D supplies current to the motor C. By gradually decreasing the speed of the dynamo D the current decreases, becomes zero, and is reversed until the circuit is opened by the device Q. At this instant the maximum value of the return current is read on the ammeter A3.

Abstract: 1,155,475. Hydrophobic starch ethers. PENICK & FORD Ltd. 14 July, 1967 [28 Feb., 1967], No. 32529/67. Heading C3U. Hydrophobic starch ethers in granule form have as substituents monofunctionally linked hydrophobic aliphatic groups of at least 3 C atoms or hydrophobic aryl-aliphatic groups of at least 7 C atoms, these groups being present to such a degree that the granules settle out of a 6% by weight suspension in neutral water after boiling therein for 30 min. at 210 F. They are made by etherification under non-gelatinizing conditions, suitably in an alcohol, ketone, toluene or water. In the latter case, carefully controlled conditions are used, which include a limited amount of alkali (e.g. NaOH or KOH) as etherification promoter, and using a salt, e.g. NaCl or Na 2 (SO 4 ) as a swelling inhibitor. In the examples the hydrophobic groups are benzyl (from benzyl chloride); allyl or methyl (from their chlorides); 1-allyloxy-2-hydroxypropyl -(from allyl glycidyl ether); p-chlorobenzyl (from p,α-dichlorotoluene); and 2- hydroxypropyl-3-phenoxy (from phenyl glycidyl ether). Corn and potato starch are exemplified. The D.S. of the ethers is suitably 0À09-0À5. These granules may be fragmented in the presence of water to produce a suspension, e.g. by cooking above 212 F. followed by a release of pressure to atmospheric, whereby particles having an average size of less than 1 micron are produced.
