Pro-Ject founder Heinz Lichtenegger began producing and selling turntables under this brand name in 1991. The Pro-Ject 1, launched in 1991, marked the company's entry into the turntable market. Developed by founder Heinz Lichtenegger, this deck was essentially a modified version of the Tesla NC-500, a turntable produced in the Czech Republic.

Retort stand. In chemistry, a retort stand, also called a clamp stand, [1] a ring stand, [2] or a support stand, [3] is a piece of scientific equipment intended to support other pieces of equipment and glassware — for instance, burettes, test tubes and flasks. [4] The typical ring stand consists of a heavy base and a vertical rod, both ...
A clamp holder or clamp fastener is a piece of laboratory apparatus that is used to secure laboratory clamps, such as extension-type utility clamps, or other attachments to a retort stand or lab frame.

The open end of the clamp is then placed over the batten, and a bolt (the "clamp bolt") is tightened to secure the c-clamp. C-clamps for stage lighting fixtures usually also have a pan screw (also known as a "grub bolt"), which when loosened will allow the clamp shaft, and therefore the fixture, to be rotated 360 degrees while maintaining a ...
A negative clamp is the opposite of this—this clamp outputs a purely negative waveform from an input signal. A bias voltage between the diode and ground offsets the output voltage by that amount. For example, an input signal of peak value 5 V (V INpeak = 5 V) is applied to a positive clamp with a bias of 3 V (V BIAS = 3 V), the peak output ...
Iron rings used in a laboratory. An iron ring or ring clamp is an item of laboratory equipment which comprises a conjoined metal ring and radially-extending rod. [1] In some cases, the rod terminates in a screw clamp for attachment to a retort stand or other support; in others, the rod may be attached to a stand by means of a laboratory clamp holder. [2]
