Title: Method of, and apparatus for, testing lubricating oils
IPC: G01N33/28
Filed: 1962-08-27
Abstract: 968,645. Testing lubricating oils; coating apparatus. BRITISH PETROLEUM CO. Ltd., A. GROSZEK, and D. J. PALMER. June 14, 1963 [Aug. 27, 1962], No. 32784/62. Headings B1X and B2B. The lacquering properties of a lubricating oil for use in an internal combustion engine are tested by cyclically inserting into and withdrawing from a bath of said oil a heated metal test piece. One portion of the test piece may be always immersed whilst another portion is always outside the oil. In a specific embodiment, the test piece, e.g. of steel, has limbs 16 and 17 joined by a connecting piece 18 and clamped to electrical terminals 19 and 20 whereby it is heated by passage of an electric current. In the Figure, the oil bath 11 is in its lowest position with the oil covering connecting piece 18 and may be reciprocated vertically by means of platform 12, rods and guides 13 and 14, and crank mechanism 15. All the parts described are enclosed in an insulated chamber to reduce heat losses and also to allow a controlled atmosphere to be used. Alternatively the test piece may have its ends embedded in a metal block maintained at 300-400 ‹C. The test piece is polished before use and after the test it is washed with petroleum ether, dried and the length of visible lacquer on each limb measured. The apparatus may also be used to investigate the type and finish of the metal surface, surface temperature and rate of oil flow over the surface on lacquer formation. The bulk oil temperature may be controlled by blowing gas directly on to the side of the reservoir, but other means for heating and/or cooling the oil in the bath may be used.

Abstract: 859,404. Safety wheels; prevention of skidding. WITZMANN, F. Oct. 17, 1958 [Oct. 24, 1957], No. 33287/58. Class 108(2). Anti-skid rollers 3, 3 are carried by a frame 2 which is retractable relative to a frame 21 which itself is retractable relative to the main vehicle frame 58. The rollers 3, 3, are driven by gearing (not shown) from a drive shaft 16. One or other bevel gear 67, 68, on a shaft 31 may be brought into engagement with a gear 69 rigid with the drive shaft of the rollers 3, 3, by the reciprocation of a rod 70 which passes via a crank 50 to a control operable by the driver of the vehicle. The shaft 31 may thus be rotated in one or other direction to move screw threaded blocks 64, 64, towards or away from one another thereby lowering or raising respectively the frame 2 relative to the sliding frame 21. The latter is supported by a linkage 18, 19, which may be manually displaced by rotation of a handle (not shown) connected to a screw-threaded shaft 16. Alternatively (as shown) the shaft 16 may be connected by a drive 71, 72, to a main drive shaft 1 of a vehicle. The main frame 58 may be secured to the frame of the vehicle by means of lugs 7 which are laterally displaceable by rotation of a screw-threaded shaft 8. In a further form of roller (Fig. 7) a series of rings 75 are mounted on an annular air cushion 77 carried by a hub 76. The rings 75 are thus able to have limited radial movement to an extent limited by the provision of radial slots 80 in each ring which are engaged by a projecting pin 79 disposed on the adjacent ring. Instead of the mechanical means for increasing the pressure of the rollers 3, 3, on the ground, electrical or hydraulic means may be employed. These may be connected with the braking system of the vehicle. The rollers may each have a brake drum having slots operable by means of the normal brake control of the vehicle.
