Title: Differential amplifier in integrated bipolar transistor circuit - uses current mirror circuits from common reference element
IPC: H03F1/56
Filed: 1988-01-26
Abstract: The two complementary pairs of PNP and NPN transistors are connected so that the PNP transistors have commoned emitters connected, via a controllable current mirror circuit, to the positive supply line. Likewise, the emitters of the NPN transistors are connected to the negative supply via another current mirror. The bases of each pair are connected together to form the signal inputs of the amplifier. The control inputs of the current mirror circuits are fed via two additional transistors by a single current reference element. The circuit avoids the need for matching the current amplification factors of the transistors, which would otherwide be necessary to achieve the correct base current compensation.

Title: Process for the whole broth extraction of avermectin
Inventor: BAGNER CARL
IPC: C07H17/08
Filed: 1982-12-20
Abstract: In the whole broth extraction of avermectins, the pH of the whole broth is adjusted with mineral acid and the broth is then contacted with a solvent extractant so that the avermectin-active component is taken up by the solvent. The new avermectin-rich extractant is then processed through a solvent concentration step and the avermectin isolated by conventional crystallization. The extractant is then recycled with appropriate make-up to extract a subsequent batch of whole broth.
Patent PT-81666-A (PT)
Title: Sight correction attachment for respirators
IPC: A62B18/08
Filed: 1985-12-12
Abstract: A sight-corrective lens (19) is attached between an eyepiece (3) of a respirator and the eye of the wearer by a monocu- lar mount (10) into which the lens fits as if into a standard spectacle frame.

IPC: B22F3/26
Filed: 1989-11-09
Abstract: The present invention relates to the formation of metal matrix composite bodies by a spontaneous infiltration technique, and novel metal matrix composite bodies produced according to the method. An ingot (4) of matrix metal is surrounded by a permeable mass of filler material (5). An infiltration enhancer and/or an infiltration enhancer precursor and/or an infiltrating atmosphere are also in communication with the filler material (5), at least at some point during the process, which permit the shaped ingot (4) of matrix metal, when made molten, to spontaneously infiltrate the surrounding permeable mass of filler material (5). After the spontaneous infiltration, a metal matrix composite body is produced having therein a cavity which substantially corresponds in shape to the original ingot (4) of matrix metal.
