The rib is provided along at least a portion of one turn of the thread such that when the fastener is mated with a cooperating conventional thread the surface 24 of the rib engages the co-operating thread and the rib is subjected to resilient compression in a direction normal to the surface and resilient axial deflection to lock the fastener and cooperating thread together. The rib preferably has a cross-section, e.g. as shown in Fig. 3, defining a substantially flat surface 24 extending parallel to the surface of a mating thread. The rib may be continuous or discontinuous and may be formed in either or both of the flanks . of the thread. The rib may be formed so that its crest is below, level or above the crest of the thread. The dies may have the portion corresponding to the locking portion of the fastener formed by a tool pressed to form the complement of the ribs on the thread forming ridges of the die prior to hardening of the die. In the case of internally threaded fasteners the thread may be formed by milling or electric discharge machining. Alternatively the thread may be formed by using a crush roll and grinding wheel.

The particles are then separated from the liquid, washed and dried by heating. The particles may then be calcined, optionally followed by complete or partial reduction. Oxidation may be effected by NO 3  derived from a solution of NH 4 NO 3  or by halogen oxy-acids. The required pH may be maintained by injection of an alkaline solution, e.g. Na 2 CO 3 , NaHCO 3  or NH 4 OH, Alternatively, oxidation may be carried out by injecting a rapid oxidant, e.g. KM 2 O 4  or NaNO 2  into the carrier suspension. In this embodiment, the rate of injection is such that the increase in the amount of Fe<SP>++</SP><SP>+</SP> in the suspension is not more than 0À05 mole per litre and per minute, and the deviations around the mean change do not exceed 0À001 mole per litre of solution. Examples describe the co-precipitation, on to SiO 2  particles, of mixed Ni-Fe oxides, mixed Co-Fe oxides and a Co-Fe oxide containing Mn (derived from KMnO 4  oxidant).

Abstract: 586,992. Distilling shale. STANDARD OIL DEVELOPMENT CO. May 28, 1943, No. 8592. Convention date, July 2, 1942. [Class 55 (i)] [Also :in Group III] A method of continuously distilling shale comprises powdering the raw shale, preheating the powder to 300-500‹F. by adding a heated gas, discharging the shale mixed with a carrier gas into a distillation zone, also discharging into the distillation zone a quantity of hot spent shale at a temperature of 1000-1600‹F., allowing the raw shale and the hot spent shale to remain in contact with each other at a temperature of 600- 1150‹F. to effect distillation, withdrawing the gaseous products from the distillation zone, withdrawing spent shale from the distillation zone and discharging it to a combustion zone in admixture with an oxidizing gas, allowing the spent shale to remain in the combustion zone to effect combustion of its combustibles and returning the burned shale to the distillation zone. As shown, the powdered shale, after preheating in a vessel 12, flows, by the action of gravity together with a carrier gas, through a pipe 20 into a distillation vessel 26 where it is mixed with hot spent shale, the gaseous products of the distillation being removed through the pipe 18 for further treatment and the solid products through the pipe 52 to a vessel 35 where, by the addition of an oxidizing gas, they are completely burned. Part of the spent shale in the vessel 35 is returned to the distillation vessel 26 through a pipe 36 and part through a pipe 67, a heat exchanger 69 and finally discharged from the system. Oil may be added to the vessel 35 if there is insufficient combustible material remaining in the shale after distillation. Temperatures are given for each stage of the process.
