Title: Improvements in or relating to the production of granular or globular polymerisationproducts
IPC: C08F2/22
Filed: 1944-07-25
Abstract: Poly-ethenoid compounds are produced in granular or globular form by a process which includes agitating a liquid ethenoid compound of limited water solubility with an aqueous medium containing 0.01 to 1 per cent by weight of an inorganic substance colloidally dispersed therein so as to produce a dispersion of the ethenoid compound and maintaining the dispersion by agitation. Specified inorganic substances are the naturally occurring colloidal clays such as bentonite, montmorillonite and the china clays.  The size of the granular or globular particles may be controlled by variation of the quantity of colloidally dispersed inorganic substance, or by variation of the ratio between the continuous and disperse phases, specified ratios being from 2 : 1 to 4 : 1 of aqueous media to ethenoid compound.  Examples are given of the polymerization of methyl methacrylate containing benzoyl peroxide dispersed in a dispersion of bentonite in water. Specifications 358,534, 427,494 and 455,742 are referred to.

Title: Improvements in liquid fuel injecting and vaporising apparatus for internal combustion engines
IPC: F02B47/02
Filed: 1922-05-22
Abstract: 202,080. Bagnulo, A. May 22, 1922. Cylinders receiving liquid fuel. - Heavy fuel is sprayed by steam generated within the combustion chamber on to a catalyst also within the combustion chamber, by means of which the fuel is broken down into hydrogen, methane, ethane, and non-saturated hydrocarbons. These latter are hydrogenated by the hydrogen, evolved by the dissociation of the steam, thus forming a combustible mixture which does not leave objectionable residues when burnt. In Fig. 1, steam from the coil F fills the space I above the valve L, and fuel from the pipe N the space H between the two valve heads K, L. On the opening of these valves, which are mounted on a common stem M, the steam and fuel pass into the catalyzing net R, whence they are carried by the compressed air entering from the cylinder B on to the hot bulb S and ignited. In a modified construction, the valve M has one head only, is suction operated, and has means whereby escape of steam to the atmosphere is permitted when the valve is seated. The amount of fuel injected is controlled by a screw-down needle valve and the catalyzing net is replaced by a flat piece of gauze fixed across the mouth of the hot bulb in such a position that the fuel and steam is injected directly thereon.

Title: Process and apparatus for the manufacture of bricks and the like
IPC: B28B3/26
Filed: 1952-06-09
Abstract: 726,929. Extruding hollow bricks. SENES, P. E. S. June 9, 1952 [June 8, 1951], No. 14486/52. Class 87 (2) Different portions a, b, c, d, &c. of a hollow brick are extruded at different speeds to prevent cracking of the bricks during subsequent drying and baking. It is stated that this cracking is caused by differences in the degree of contraction of various parts of the brick during drying and, further, that the degree of contraction increases with the speed of extrusion of these parts. Hence, by suitable design of the aperture r of the extrusion nozzle k the speed of extrusion and, consequently, the degree of contraction of the various portions a, b, &c. of the brick may be adjusted to produce a brick having a uniform degree of contraction. The speed of flow of the portions a, b, &c. through corresponding regions of the aperture r may be increased by (a) increasing the width of the aperture, (b) reducing the length of the parallel-sided portion of the aperture, and (c) adjusting the degree of chamfer i to about 35 degrees-40 degrees at which value it will present minimum resistance to the clay. An indication of the required increases and decreases in extrusion speed of the various parts may be found by extruding a brick using an ordinary non-adjusted nozzle, cutting this brick in the direction of extrusion into portions a, b, &c. and measuring the degree of contraction of each portion.
