Title: Improvements in and relating to motor road vehicles
IPC: H01B11/12
Filed: 1923-07-06
Abstract: 227,136. Holle, A. A. July 6, 1923. Addition to 207,595. Axles and axle structures; radius rods and torque rods. - The independently-pivoted non- rotating axles described in the parent Specification are each formed of two elements 3, 4 of unequal length, the upper element being the shorter and pivoted to the frame at a point 13 farther from the central longitudinal axis of the vehicle than the pivot 9 of the lower member; also each of the radius and torque rods connecting the axles and the centrally-disposed differential casing is formed of two members 3*, 4* having pivots in line with those of the axle members 3, 4. The road wheel thus moves substantially in a vertical plane. The drawing shows a steering- wheel only, but the driving-gear of the parent Specification may be employed. The link 16 connecting the stub-axle arms 17 is provided with ball joints 15 disposed in planes containing the pivotal axes of the axle members and radius rods, and this, link is actuated by the steering rod 19 through an arm 20. In a modification described in the Provisional Specification the arms 3, 4 may be of equal length so that the wheel always remains parallel to its original position, and the arms may be formed of springs, some of the pivots being dispensed with.

Title: Process for electroplating metals with chromium
IPC: C25D21/11
Filed: 1929-06-17
Abstract: 327,911. Bauer, J. June 17, 1929. Chromium, depositing.-In plating with chromium escape of the corrosive bath in the form of spray is prevented by lowering the surface tension of the bath so as to cause the bubbles to burst immediately on emergence; this may be done either by the addition of a small quantity of a liquid having a small surface tension such as petroleum or gasoline which is shaken up with water and added with stirring to the bath, or by subjecting the surface to heat radiation from incandescent wires arranged near the anode and cathode. The bath may consist of 40 gms. chromic acid, 5 gms. chromium sulphate and 5 gms. magnesium carbonate per litre; 0.5 c.c. of petroleum per litre is a sufficient addition.
