Title: Improvements in and relating to motor operated agricultural tractors
IPC: B62D49/06
Filed: 1934-06-23
Abstract: 429,657. Implements and machines for working land. DUFOUR, L., Villa Henri, Versoix, Geneva, Switzerland. June 23, 1934, No. 18606. Convention date, June 24, 1933. [Class 6 (i)] [See also Group XXXI] A tractor comprises two distinct parts one of which includes the main frame and wheels while the other part is pivoted to the frame so as to swing about an axis coincident with or parallel and close to the driving wheel axle and is provided at its rear end with coupling means to which an implement or load may be attached. In the construction shown in Fig. 3 the tractor frame 1 is supported on a steering wheel 9 and a pair of driving wheels 6 mounted on an axle 5. The power unit comprising engine 13, fuel tank 15 and gear-box 14 is mounted on and drives the axle 5 and is pivoted at 28 to the frame 1. A draw-bar 23 is pivoted at 22 to the power unit and is connected by a hook 24 to the load. When a load is being hauled the power unit rotates about the pivot 28 until a balancing position is reached, as shown, there being thus practically no tendency for the frame 1 to overturn. A roller 25 limits the downward movement of the drawbar. When there is no load being drawn the front end of the power unit overbalances the draw-bar end and rests on a bar I<1> on the frame. In the construction shown in Fig. 5 the power unit is pivoted on the axle 5 which is mounted directly on the main frame 1. A plough beam 34 is adjustably secured at 32 to an arm 31 secured to a flange 21<1> at the rear of the power unit. The plough is raised and lowered by rotating the power unit about the axle 5 by means of a hand lever 38 pivoted at 38a on the main frame. An arm 39 carries a roller 40 acting on a cam surface 41 fixed to the power unit, so that when the lever is in the position shown the plough is raised and is held in the raised position since the roller 40 has passed over its dead centre. When the hand lever is rotated in the counter-clockwise direction the power unit is freed and the weight of the plough causes the latter to descend. Power assistance may be obtained for lifting the plough by reversing the drive to the axle 5, when the power unit will rotate in the counter-clockwise direction. In Fig. 6, (not shown), a rotary cultivator is fixed to the flange 211 and is driven from the power unit.

Title: Unsaturated polyesters and polyester resins
Inventor: JENKINS VICTOR FREDERICK
IPC: C08G63/553
Filed: 1958-06-13
Abstract: Unsaturated polyesters, melting at not less than 75 DEG C. and copolymerizable to give resins free from surface tackiness contain the residues of an aliphatic, olefinically unsaturated polycarboxylic acid (e.g. maleic or fumaric) and alicyclic diol residues of formula <FORM:0923691/IV(a)/1> in which m=0 or 1, n=0 or 1 and R1, R2, R3 and R4 are hydrogen atoms or alkyl groups containing not more than 4 carbon atoms.  The polyesters may also contain the residues of a conventional glycol (e.g. ethylene-, diethyleneor 1:2-propylene-glycol) and a saturated dicarboxylic acid, (e.g. succinic, adipic, phthalic, isophthalic or terephthalic acid or a partially or completely hydrogenated derivative of phthalic, isophthalic or terephthalic acid).  Coating compositions are made by dissolving the polyester in styrene, possibly together with a solubilising agent, (e.g. butylacetate or acetone) and adding a conventional polymerization catalyst.  In an example, a polyester obtained by reacting cyclohexene-1:2-diol, 1:2-propylene glycol, maleic anhydride and phthalic anhydride in the presence of hydroquinone was dissolved in styrene and methyl ethyl ketone peroxide and cobalt naphthenate were added to form a lacquer.
