Ludwig acquired the Musser Mallet Company, a manufacturer of xylophones, marimbas and vibraphones, in 1965. [2] Ludwig was a strong presence in the marching drum market. During the 1970s, Ludwig's "Challenger" line of snare drums offered sophisticated tuning and strong build quality. Ludwig drums were used by many leading drum and bugle corps.
Conn-Selmer, Inc. is an American manufacturer of musical instruments for concert bands, marching bands and orchestras.It is a wholly owned subsidiary of Steinway Musical Instruments and was formed in 2003 by combining the Steinway properties, The Selmer Company and United Musical Instruments.
Aluminium bronzes are most valued for their higher strength and corrosion resistance as compared to other bronze alloys. These alloys are tarnish-resistant and show low rates of corrosion in atmospheric conditions, low oxidation rates at high temperatures, and low reactivity with sulfurous compounds and other exhaust products of combustion.
The Ludwig trademark was bought by William F. Ludwig Sr. of the WFL Company who saw the opportunity to buy back the family name, while the Leedy trademark was sold to Slingerland Drum Company. [29] George Way, who had already departed the company a year prior, started his own drum company in 1957, housed in the former Leedy & Ludwig production ...
S-Meter of a Ten-Tec Orion amateur radio transceiver. An S meter (signal strength meter) is an indicator often provided on communications receivers, such as amateur radio or shortwave broadcast receivers. The scale markings are derived from a system of reporting signal strength from S1 to S9 as part of the R-S-T system.
The strength of materials is determined using various methods of calculating the stresses and strains in structural members, such as beams, columns, and shafts. The methods employed to predict the response of a structure under loading and its susceptibility to various failure modes takes into account the properties of the materials such as its yield strength, ultimate strength, Young's modulus ...
Silver, although it is the least resistive metal known, has a high density and performs similarly to copper by this measure, but is much more expensive. Calcium and the alkali metals have the best resistivity-density products, but are rarely used for conductors due to their high reactivity with water and oxygen (and lack of physical strength).
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
