What is B and D tooling in tablets?
Tablet compression machines are made in keeping in view the type of dies and punches will be used on them, The dies and punches and their setup on compression machine is called tooling, it is classified as B and D mainly.
What are tablet defects?
Tablet defects are deficiencies that are usually encountered in tablet formulation. Depending on experience, machinery and excipient used, produced or compressed tablets can develop certain defect which may be immediately apparent or appear only after storage.
What is Hollerith machine?
The tabulating machine was an electromechanical machine designed to assist in summarizing information stored on punched cards. Invented by Herman Hollerith, the machine was developed to help process data for the 1890 U.S. Census.
Why is it called a tablet?
The word tablet comes from either the Medieval Latin ‘tabuleta’ meaning ‘table’ or the Old French ‘tablete’ meaning ‘small table, display counter’. It first appeared in English in the early 1300s to describe a flat stone used to write on, though alternative uses came later.
What is the first tablet?
In 1989, Jeff Hawkins, the founder of Palm Computing, created the GridPad. Some call this the first tablet computer. It ran MS-DOS and the military bought a few but consumers mostly ignored it. It was pricey and heavy compared to laptops of the era.
Why friability test is done?
Pharmaceutical. Friability testing is a laboratory technique used by the pharmaceutical industry to test the durability of tablets during transit. This testing involves repeatedly dropping a sample of tablets over a fixed time, using a rotating wheel with a baffle.
What is capping and lamination?
Capping is the partial or complete removal of the crown of a tablet from the main body, while lamination is the separation of a tablet into two or more distinct layers.
How do you solve friability problems?
As the card is inserted, the punch card reader starts on the top-left side of the card, reading vertically from top to bottom. After the card reader has read a column, it moves to the next column. As the reader read the information, it would be written to a computers memory.
How did the Hollerith tabulating machine work?
Hollerith Tabulator Dials
The electrical impulses received as the reader’s pins passed through the card into the mercury advanced the hands on the dials corresponding to the data contained on the punch card (i.e., responses to inquiries about race, gender, citizenship, age, etc).
What is mechanical tabulation?
(2) The counting of the coded items falling into different classes or groups. The former process, cannot be mechanized and in some cases requires special. knowledge; the latter process when mechanized is known as “mechanical tabulation “.
What is the price of a tablet?
You can get a tablet for as low as under Rs 10,000 and as high as above Rs 40,000. Brands like Samsung, Xiaomi, Lenovo, Huawei, Honor, and more are actively launching tablets for its customers in India.
Is a tablet a computer or a phone?
