Title: Improvements in or relating to bituminous or like emulsions
IPC: C08L95/00
Filed: 1928-02-16
Abstract: 308,051. Montgomerie, J. A. Feb. 16,1928. Emulsions, making.-Aqueous emulsions of asphalt, particularly Mexican or like artificial asphalt, or of bitumen, tar, or mineral or other pitch are prepared by adding to one or a mixture of these ingredients a small quantity, for example 1-5 per cent, of animal or vegetable pitch such as cotton stearine pitch or wool-grease pitch and adding this mixture in a molten or fluid condition to a hot dilute aqueous solution of alkali such as caustic soda or potash, sodium or potassium carbonate, bicarbonate, phosphate or silicate. The prepared emulsion may be mixed with one or more other emulsions prepared by the same or by a different process, for example that described in Specification 226,032. In a modified process the principal ingredient is dissolved in a solvent such as naphtha, and subsequently mixed with the other ingredients. A colloid mill may be employed to mix the ingredients or to homogenize the prepared emulsion. A small proportion of soap may be added to the finished emulsion, for example 0.25 per cent of sodium laurate.

Abstract: 1,170,106. Making tubular filters. BENDIX CORP. 3 Feb., 1967 [10 Feb., 1966], No. 5328/ 67. Heading B8G. [Also in Division F2] A machine lays a plurality of resin-impregnated creped strips helically on to a rotating mandrel along which they move and are cured to form a filter tube of controlled porosity. A number of pairs of strips are supplied through slots (Fig. 3, not shown) in a member 26 on to a rotating, tapered hollow mandrel supplied with air under pressure whose flow is metered by a device 66. A dielectric heater is movable over the mandrel by means 62 controlled from the device 66. As the heater 60 cures the strip the strip shrinks and grips the mandrel so that the air pressure is not so easily able to escape through the tube and the flow decreases. The means 62 then moves the heater 60 along the mandrel so that the strip is cured at a different place on the tapered mandrel until the air flow, and thus the porosity of the tube, is at a desired level.

A typical rectifier is made by heating a pure cadmium telluride wafer for 5 hours at 900‹ C. at a partial cadmium pressure of 1 atmos. to give an electron density of 7 x 10<SP>16</SP>/c.c. After vapour deposition of cobalt on one face the wafer is heated in a two-part oven at 900‹ C. for 15 minutes at 1 atmos. cadmium pressure and cooled quickly to room temperature. After grinding the uncoated surfaces and etching first in nitric acid and then in a boiling mixture of sodium hydroxide and hyposulphite the body is dried. An indium ohmic electrode is alloyed to the N zone and gold deposited on the cobalt doped P layer from auric chloride solution. A photo-electric device is made by doping an elongated body of cadmium telluride with 5 x 10<SP>17</SP> atoms/c.c. of vanadium, or roughly similar amounts of nickel, chromium or cobalt using zone refining techniques. The resulting body is heated at 900‹ C. for 5 hours in 1 atmos. cadmium pressure and cooled rapidly to room temperature to produce a resistivity of at least 10<SP>7</SP> ohm. cm. The cadmium pressure is not critical and wide ranges are specified as being suitable. Finally tellurium is alloyed or goldplated on the ends of the body to provide ohmic contacts.

An insulator 1 has fastening means by which it is secured to a post, and a support 2 for a wire, the fastening means comprising spaced grippers 5, 6 and a locking element 9 which is resiliently displaceable relative to the grippers and co-operates therewith to hold the insulator on the post, the grippers having projections 7, 8 to embrace the post and faces 11, 15 to engage with opposite sides of the post and co-operate with face 10 on locking element 9 to secure the insulator in position. The locking element may have an inclined cam surface 12 and the front face of the insulator may have a raised portion 13 with ridges 14 thereon. To position the insulator, it is placed so that the post A is engaged transversely between the grippers 5, 6. The insulator is then rotated so that the post engages behind projections 7, 8 at the same time riding over cam surface 12 causing the locking element 9 to be displaced. When the post clears face 10, the element 9 moves back into position so that faces 10, 11 engage one side of the post and face 15 the other side, to prevent lateral displacement. Projections 7, 8 and ridges 14 prevent vertical displacement. The insulator may be moulded from rubber or polythene and may have a metal reinforcing plate embedded therein.
