Title: Method of producing cement or cement-like materials from oil shale
IPC: C04B7/30
Filed: 1961-03-08
Abstract: A cement or cement-like material is produced from oil shale, which, when calcined alone, gives a material not suitable for use as a cement or cement-like material, by milling to a grain size of 0.1 mm. or less and either during or after the milling mixing with an amount of clay, lime and/or like material useful in the manufacture of cement to result in a finished product which is a cement or cement-like material, wherein the mixture is then pelletized and calcined in a fluidised solids reactor at above 400 DEG  C.  The fluidising gas may contain free oxygen to burn the organic constituents of the shale.  The cohesion of the pellets may be increased by incorporating burnt lime, cement, bentonite, or spent liquor from the sulphite process in such quantities that the pellets will disintegrate to a fine dust during calcination.

Abstract: Bacillus cereus var. galleriae, morphological and cultural characteristics of which are disclosed, is cultivated on an initially sterile liquid medium of pH 6.6 - 7.2 containing specified proportions of maize extract, molasses, glucose or pea hydrolysate, and sunflower oil or spermaceti fat as an anti-foaming agent.  On a large scale the fermentation is conducted with intermittent stirring in vats held at a temperature of 30 DEG -31 DEG C. for between 36 and 48 hours, and 0.8-1.0 litre of air is blown through the medium in the vats per minute for each litre of medium.  The fermentation is stopped when 90-95% of the cells of the organism have produced spores and the spores have escaped from the cells, and 0.5% of kaolin is then added to the liquid medium.  The whole culture is stirred and the kaolin with the spores is separated as a paste which is freeze-dried to 3% moisture content.  The freeze-dried material is ground to dust in a ball mill.  The dust, further diluted with kaolin or chalk and containing 3 X 109 spores per gram, is applied as an insecticide to flower or vegetable crops.ALSO:An insecticidal dust consists of spores of Bacillus cereus var galleriae (3x109 per gram of dust) and kaolin or chalk.  It may be applied, preferably at a temperature of at least 20 DEG C., to flower crops (3-5 Kg. dust per hectare) and vegetable crops (1-3 Kg. dust per hectare), both during the blossoming period and shortly before harvest.  In order to increase the efficiency of kill at low temperatures, 0.002-0.005 of DDT or hexachloro-cyclohexane may be included in the dust. Alternatively the spores of Bacillus cereus var. galleriae can be applied directly by spraying.

Abstract: 231,002. English Clock & Watch Manufacturers, Ltd., and Walferd, H. N. April 7, 1924. Chimes; striking-mechanism.-In a two-train striking and chiming clock the chiming-mechan. ism is reversed to zero periodically, the striking and chiming mechanisms are both controlled so that only one is operative at a time, the other being held positively inoperative, and means is provided to ensure that the chiming mechanism is always correctly in step with the going train. The arbor C carrying the lifting-wheels D for actuating the tails E of the chime-hammers E<1> and the hour-striking hammer arbor Fare mounted so as to be displaceable axially, and the former carries a disc C<1> provided with a pin C<2> forming a clutch connection with a pinion G of the chiming-train while the latter carries a pin F<1> adapted to be moved into and out of the plane of rotation of a star-wheel H of the striking-train. A tumbler L is pivoted at K on a member J and is formed with tailpieces L', L<2> bearing on the ends of the arbors C, F, the. tumbler L being rocked to effect the axial displacement of the said arbors through a pin M accommodated in a slot L<3>, the pin M being carried on a lever N pivoted at N<1> and having at its lower end a pin N<2> received in a cam-groove O formed in a disc P making one revolution per hour. Rearward movement of the arbor C declutches the disc C<1> and pin C<2> from the pinion G and carries the lifting-wheels D out of the planes of the tails E of the hammers E<1>, while rearward movement of the arbor F carries the pin F<1> out of the plane of rotation of the wheel H, such movements taking place respectively against the action of springs Q. R, while, after axial displacement of the arbor C the said arbor is returned by a spring S to its zero position which is determined by a pin T contacting with a stop U on a plate V. In Fig. 1 the mechanism is shown in position after an hour has struck and the striking- mechanism is inoperative, the chiming-mechanism being positioned to strike the three quarters. During this time the disc P will revolve and the pin T travel round to the rear side of the stop U. Ultimately the cam-groove 0 moves the lever N and causes it to rock the tumber L to de-clutch the chiming-arbor C, which is thereupon returned to its zero position by the spring C, the arbor F simultaneously moving forward in readiness to strike the hour. After the hour has struck the cam-groove 0 again operates the lever N and tumbler L and the mechanism returns to the position shown in Fig. 1.
