Abstract: 389,996. Drums &c. for asphalt. SANDERS, J. M., St. Helens Court, Leadenhall Street, London. April 13, 1932, No. 10590. [Class 21.] Barrels, drums, and other metal containers for asphalt (including under this term all solid, semi-solid or plastic bituminous substances such as bitumen, tar or pitch, whether derived from naturally occurring deposits or obtained artificially by the distillation, evaporation or concentration of crude petroleum, coal tar or like materials or from derivatives thereof, which have a tendency to adhere to the surfaces of metals), are treated on their inner surfaces, to facilitate separation by physical force of the asphalt, with a liquid or semiliquid film or coating which is such that its work of adhesion for the container surface is greater than the work of cohesion of the coating, and the work of cohesion of the coating greater than the work of adhesion for the asphalt, in order that the coating may more readily wet, adhere to and combine with the container surface than the asphalt. The coating may consist of aqueous solutions of salts such as chlorides, nitrates, sulphates, bisulphates, thiosulphates,'sulphites, bisulphites, or ortho-, meta-, or pyrophosphates of alkali metals and ammonium, the chlorides or nitrates of the alkaline earth metals or the chlorides, nitrates, or sulphates of iron, aluminium, zinc, manganese, or magnesium, potassium soaps, or the alkaline salts of the fatty acids mixed with polyhydric alcohols such as glycerol. The coating may also consist of aqueous solutions of bases and acids capable of interacting to form water-soluble salts, e.g. carbonates, bicarbonates, or sulphides of the alkali metals or ammonium or of iron, aluminium, zinc, manganese, or magnesium, mixed with aqueous solutions of free acids or acid salts in such proportions as to produce salts of the metals and generate carbon dioxide or hydrogen sulphide. Free acids which react with the metal of the container or with iron, zinc, or aluminium added as powder, and generate a gas may also be used, e.g. aqueous sulphuric, hydrochloric, nitric, or phosphoric acid. Also a mixture of aqueous alkalis such as sodium or potassium hydroxides and aluminium powder may be used. Filling agents such as black oxide of iron or graphite with or without suspending agents such as sodium pyrophosphate, sodium silicate, tannin, or, other known dispersing agents, and substances like sodium bicarbonate or ammonium carbonate which liberate gas when heated may be employed, and the films may contain dissolved or occluded gases such as air, carbon dioxide, or hydrogen.

Title: Metallisation of non-metallic surfaces
Inventor: DRAKE CYRIL FRANCIS
IPC: C23C18/44
Filed: 1947-04-24
Abstract: Non-metallic surfaces (other than hydrocarbon polymers such as polystyrene or solid polymers of ethylene) are coated with metal, particularly silver, by reducing a metal salt in solution in the presence of an anionic surface active agent such as the alkali metal or alkaline earth metal salt of a sulphonated long chain fatty alcohol, and depositing the metal from the said solution on an activated area of the surface.  Preferably the sodium salt of sulphonated lauryl alcohol is used and when silvering is added to an ammoniacal solution of silver nitrate in amount not exceeding 0.2 per cent by weight of the solution, formaldehyde being added for the reduction either before or after immersing the surface in the solution.  Activation is achieved by e.g. treating the surface with a solution of stannous chloride in hydrochloric acid, or (when copper is to be deposited) with dilute solutions of the chlorides of the noble metals-gold, platinum &c.  In this manner required parts only of a non-metallic surface may be metal-coated, e.g. electrodes of any desired shape or area may be deposited on quartz piezo-electric crystals; also the interior of a narrow bore glass tube may be silvered uniformly.  Non-metallic surfaces particularly referred to are glass, mica, quartz, and synthetic resins of the acrylic acid group.

Title: Improvements in automatic telephone systems
IPC: H04Q3/42
Filed: 1939-04-12
Abstract: 527,441. Automatic exchange systems. ELECTRIC RESEARCH PRODUCTS, Inc. April 12, 1939, No. 11063. Convention date, April 13, 1938. [Class 40 (iv)] In a system in which numerical selection by the subscriber is performed by means of keys each of which controls the application of alternating current of a characteristic frequency to the line, the selecting currents are derived from a harmonic producer which is fed with the fundamental frequency from the exchange. Preferably the harmonic producer is a toroidal coil on a permalloy core. The tuned selecting circuits made up by depressing the keys are divided into two groups, one of which uses the whole, and the other only a part of the inductance 161. In the system shown a calling subscriber is extended in known manner to a group selector S which is associated with a register-sender in which a fundamental frequency generator 200 is permanently connected to the in-impulsing circuit and in which line relay 209, release relay 214 and the first relay 300 of a number of digit distributing relays pull up. A tone signal goes back from 215. When any of the digit keys is operated the telephone set is disconnected arid transformer 164 is connected up in its place. Alternating current from the source 200 then excites the harmonic producer and one of the harmonics is selected by the depressed key and transmitted back over the line to .energize the corresponding receiving relay such as 217. This energizes a common relay 218 and an individual auxiliary relay such as 219 which locks and energizes the corresponding relay or group of relays in the A register. When the key is released, the receiving relay and the common relay 218 and shortly afterwards the auxiliary relay fall back, but before the relapse of the latter the register relay or relays lock up over relay 303 which releases the fiist digit distributing relay 300 and energizes 304 to connect up the next register. The remaining digits are registered in the same way.. The relay registers may operate as described in U.S.A. Specification 1,862,549.
