Jesse Besser (1882–1970) was an inventor and manufacturer from Alpena in the U.S. state of Michigan.He is best known for inventing, and supervising a series of improvements to, a tamping machine used to rapidly press wet, flexible concrete into blocks, thereby making possible a new generation of applications in masonry construction.
A pallet of "8-inch" concrete blocks An interior wall of painted concrete blocks Concrete masonry blocks A building constructed with concrete masonry blocks. A concrete block, also known as a cinder block in North American English, breeze block in British English, or concrete masonry unit (CMU), or by various other terms, is a standard-size rectangular block used in building construction.
Accuracy: Panels and blocks made of autoclaved aerated concrete are produced to the exact sizes needed before leaving the factory. There is less need for on-site trimming. Since the blocks and panels fit so well together, there is less use of finishing materials such as mortar.
A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.
All ISO paper sizes have the same aspect ratio, one to the square root of 2, meaning that a document designed for any given size can be enlarged or reduced to any other size and will fit perfectly. Given this ease of changing sizes, it is of course common to copy or print a given document on different sizes of paper, especially within a series ...
It would be nice to have a chart of standard CMU sizes in this article. Anyone? —The preceding unsigned comment was added by 24.149.184.142 15:06, 8 April 2007 (UTC). I also believe it would be helpful to mention their modularity with brick sizes. In the US one CMU block is both the same width and depth as two bricks plus a mortar joint.
Gauge blocks (also known as gage blocks, Johansson gauges, slip gauges, or Jo blocks) are a system for producing precision lengths. The individual gauge block is a metal or ceramic block that has been precision ground and lapped to a specific thickness. Gauge blocks come in sets of blocks with a range of standard lengths.
The original Besser block machine is on display at the Besser Museum. Herman Besser was involved with the Alpena Portland Cement company. In 1904, his son, Jesse Besser, developed the first hand-tamp block machine. This technology ‘revolutionized the block-making industry” and the Besser Company was born.
