Abstract: 1,212,951. Clutch combinations; change speed control. HONDA GIKEN KOGYO K.K. 19 Feb., 1969, No. 9104/69. Headings F2C and F2D. A control for an hydraulically operated bridging clutch 2 of a torque converter comprises an engine driven pump 13 supplying pressure liquid to the clutch 2 through a valve 21 responsive to the speed of the torque converter input 3a or output shaft 3b and a valve 15 responsive to the reaction torque on the reactor 6 of the torque converter 1 so that the clutch 2 is engaged when the speed exceeds a predetermined value and the reaction torque is zero (i.e. at the torque converter coupling point). Pressure liquid supplied from a generator 27 at a pressure proportional to the torque converter input or output speed acts on the left end of a spool 25 of the valve 21 against the bias of a spring 28. When the speed exceeds the predetermined value the valve spool 25 moves right to interconnect inlet and outlet ports 29, 30. The speed at which the valve spool 25 moves right may be adjusted by a lever 33. Differential lands 23, 24 provide an additional leftward bias to the valve spool 25 below the predetermined speed and thus prevent hunting. The valve 15 is formed by a duct 19 in a shaft 8 fast with the reactor 6. When the reactor torque is zero a spring 16 urges the shaft 8 to the position shown in which the duct 19 is aligned with a supply duct 20. Reaction torque on the reactor 6 rotates the shaft 8 against the spring 16 to close the valve 15. Operation.-When the speed exceeds the predetermined value the valve 21 opens to supply pressure fluid to the valve 15 which opens to engage the clutch 2 when the reaction torque on the reactor 6 falls to zero. The clutch 2 remains engaged until the speed falls below the predetermined value whereupon the valve 21 closes to disengage the clutch 2.

Title: Soil stabilization
IPC: C09K17/14
Filed: 1960-03-16
Abstract: 868,948. Stabilizing soil. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N. V. March 16, 1960 [March 18, 1959], No. 9271/60. Class 68(1). Soil is stabilized with a doped cut back or a doped cut back emulsion, the dope for the preparation thereof comprising a solution of alkali metal, preferably sodium and potassium, soaps of oxidized and/or unoxidized carboxylic acids having at least 12 carbon atoms in the molecule, in a solvent consisting of at least 50% by weight of a creosote oil having a phenol content of at least 20% by weight. The creosote oil may contain a petroleum fraction, and the acids may be oxidized fatty acids which are also polymerized. The choice cut back depends upon such factors as the nature of the soil to be stabilized and the atmospheric conditions, and guidance in this respect is furnished. An example of a cut back is 15% by weight of heavy gasoline (boiling range 100-160‹C.) and 85% of straight-run petroleum bitumen having a softening point (Ring and Ball) of 47‹C. and a penetration (100g. 5 sec, 25‹C.) of 90. The doped cut back is made by adding the dope to the slightly heated (not more than 95‹C.) cut back, 12 parts of dope and 88 parts of cut back being referred to. If stabilization is to be effected with a doped cut back emulsion, 10-20 parts of dope is emulsified with 90-80 parts of cut back and water, the minimum amount of water being 14 parts. Further water may be added on the site to reduce transport costs. Depending on the acidity or alkalinity of the soil an auxiliary additive 0À5 to 3% based on the weight of the dry soil, may be mixed with the binder and the soil, e.g. lime, aluminium sulphate, magnesium calcium, strontium or barium oxides or hydroxides. Instead of aluminium sulphate, any water-soluble polyvalent metal salts permitting the formation, witn the soaps present, of salts insoluble in water but soluble in bitumen, may be used, e.g. copper sulphate, ferrous sulphate, ferric chloride, magnesium chloride, zinc chloride, calcium chloride or lead nitrate. Specifications 537,567 and 561,266 are referred to.
