Powder Metallurgy Looks Towards the Future

1. Developments and advances in powder metallurgy, a technology created some 50 years ago, can save manufacturing industry great amounts of valuable materials. Powder metallurgy is a cheap alternative to many conventional manufacturing processes.

2. When components, simple or complex, require precision and high quality at a comparatively low cost – powder metallurgy can provide the solution of the problem. An important feature of powder metallurgy is that it can provide the industry with such material compositions which are not achievable by any other means.

3. Components produced by the powder metallurgy process can go straight into the manufacturing cycle or, if required, undergo further processing, including heat treatment. Powder metallurgy is finding new applications in various industries - in electronics, aviation, machine-building, etc.

4. The unique physical properties of powder metallurgy parts enable oil to be retained in minute porous cavities¹ within the part. This self-lubricating characteristic ² is long lasting and can eliminate other lubrication systems.

5. The Byelorussian research and production association for powder has developed a number of processes for powder metallurgy components production. The source material there is metal powder which is subjected to high pressure to acquire a required shape and is then put to thermo-electric furnaces. The resultant parts are more durable and require no additional machining.

Пояснения к тексту:

1.minute porous cavities - крошечные пористые пустоты

2.self-lubricating characteristic - свойство, обеспечивающее самосмазывание деталей

Transmitting Pictures by Telephone.

1. Pictures can now be sent over the telephone by sound signals. A new machine does this by looking at a picture and telling what it sees over the telephone to a similar machine at the receiving end, which then translates the sound signals it hears back into the form of a picture.

2. At the sending end, the photograph, drawing business form or document is placed in the machine. At the receiving end, the reproduction appears on ordinary paper. An illustration of ordinary letter size takes six minutes to be received and reproduced.

3. This is how the machine works. Inside the machine optical devices rotate and works pick up reflected light which is focused on and passed through a filter to a photocell or «electronic eye».The photocell generates a signal which is amplified to produce voltages of varying strength.

4. The voltages are converted into sound, and it is this audible signal which is transmitted over the telephone, just as music or voice transmitted.

5. At the receiving telephone, the sound is reconverted to an electronic signal and then into a varying voltage. This voltage is aplied to a drive mechanism. The mechanism is activated to extend and print out a corresponding dark area of the transmitting picture. The length of the document determines the time needed for transmission.
