In a power transmission, particularly for a front-loading shovel, wherein an input shaft 14, I.C. engine-driven through a wheel 22, drives a first, propulsion drive, output shaft 46 through a torque converter 18 and a second, shoveloperating, P.T.O. shaft (not shown) through gears 26, 20, the torque converter impeller blades 32 are adjustable, rotatably about their own individual axes, under manual-hydraulic control, so as to adjust the division of torque transmitted to the propulsion drive and P.T.O. shafts. The torque converter comprises the impeller blades 32, a turbine 40 connected to the output shaft 46; and a stator 38. The idler 20 of the P.T.O. drive train is journalled on a stub shaft 21 by bearings 20a lubricated from the torque converter interior through a flat on the stub shaft or through a conduit 18a and an axial bore 25 and radial bores 27 in said stub shaft. The impeller blades 32 are journalled, by their bosses 34, 36, in an impeller hub and have eccentric pins 64 by which they are connected, by links 62, to a shift ring 58. The shift ring is helically splined to a plunger 52 so that axial movement of the latter effects rotation of the shift ring and rotation of the blades 32 about their own axes. Rotation of the plunger 52 is prevented by blocks 70 engaging plunger radial sectors 54. The plunger 52 comprises a piston portion 76 fast thereon and an L-sectioned piston portion (84) slidable thereon. The piston portions 76, (84) co-operate with a stepped cylinder 72, 74 in the impeller hub to provide three chambers 82, (92), 90 which are hydraulically (pump) energized and vented under the control of spring-biased valves 98, 100 respectively acted on by heel and toe pressure on a pedal 104. In the Fig. 5 position, the chambers 82, 90 are energized to mid-position the plunger 52 for impeller blade exit angle corresponding to normal, substantially equally divided torque, transmission. In Fig. 4 (not shown), heel actuation of the pedal 104 depresses the valve 100 so as to respectively vent and energize the chambers 82, (92) and leftwardly position the plunger 52 for impeller blade exit angle corresponding to greater torque transmission to the propulsion drive. In Fig. 3 (not shown), toe actuation of the pedal 104 depresses the valve 98 so as to vent the chamber 90 and rightwardly position the plunger 52 for impeller blade exit angle corresponding to greater torque transmission to the P.T.O. drive.

[Also in Divisions B2 and B3] Steel sheet is treated by coating the surface with zinc, lead, or a zinc or lead based alloy, and applying a further coating of a higher carboxylic acid or a mixture thereof with an amine, the higher carboxylic acid or mixture thereof being solid at ambient temperature. The term "higher carboxylic acid" is defined as any carboxylic acid having eight or more carbon atoms e.g. saturated fatty acids having no less carbon atoms than caprylic acid, corresponding unsaturated fatty acids, hydroxy carboxylic acids, naphthenic acid, dicarboxylic acids, natural products such as animal oil fatty acids, hardened animal oil fatty acids, vegetable oil fatty acids, hardened vegetable oil fatty acids, petroleum acids. Examples of specific acids are given. A thin layer of metallic-soap is said to be formed by reaction of the metallic coating with the higher carboxylic acid at the interface therebetween. The treatment may form the preliminary lubricating step in a process of forming steel sheet e.g. by press forming, drawing and stretching. The metallic coating may be applied by electro-plating, chemical plating or by hot-dip plating. A layer of hydrated metal oxide e.g. hydrated chromium and/or silicon oxide may be applied to the metallic coating before application of the higher carboxylic acid to improve adherance and reduce rust formation. Amines mentioned are lauryl, cyclohexyl, di-iso-propyl, di-cyclohexyl, triethyl amines, di-amino-propane, oxazines and imidazoles. The higher carboxylic acid may be heated or dissolved in an organic solvent and applied to the steel plate by roller, spray, brush, mop, dip or flow coating or by spreading and reflowing by heating with an infrared beam or hot air. One or both sides of the steel sheet may be treated. The higher carboxylic acid coating can be removed by an alkaline degreaser or an organic solvent, and the metallic coating may if necessary be removed by an acid or strong alkaline solution after the forming operation.
