Template for suspending saw frame - has blocks cut from strand produced by tube fitting inside U=shaped bar
High speed control stage for data transmission switching - uses complementary transistors to provide fast switching control of diode bridge
Amplifier with two transistor stages - has two transistors in each stage in series, with junction point of second stage being amplifier output
Electric parameters measuring circuit - includes galvanometer and can supply test current or test voltage to object
Peristaltic pump with several rollers - has hose supported over smaller angle than that between successive rollers
Protective enclosure for young tree - uses sheath made up of flexible plastics net attached to stake
