Patent FR-2689337-A1 (FR)
Title: Portable high efficiency UHF and microwave power amplifier - has weakly saturated transistor switching between high and low impedance state and giving antiphase current and voltage output
Inventor: HAILA WANG
IPC: H03F3/217
Filed: 1992-03-26
Abstract: The active element (10) is a heterojunction bipolar transistor (10) operating in a region of weak saturation so that the saturation time is at most one-third of the total operating time. The switching is determined by a control circuit (70,80) and the operating region is set by two voltage sources (20,30). The load comprises a first part (40) with at least one capacitor (41) and inductor (42) in series, and a second part (50) with a series inductor (62) and parallel capacitor (50). These ensure anti-phase operation and a reduction in the transition times between open and closed states to reduce power dissipation. The load impedance and transistor capacitance ensure large attenuation of harmonics. USE/ADVANTAGE - Frequencies above several hundred MHz, esp. battery powered. About 80 percent efficiency at 1 GHz with 100 MHz bandwidth. Second order harmonic rejection better than 70 dB.

Title: Can or plastics bottle crusher, designed for domestic use - has guide for piston with vanes which interact with sides of container and hollow tube which perforates it
Inventor: PIERRE ASTIER
IPC: B30B9/32
Filed: 1992-03-30
Abstract: The crusher consists of a component (1) with a central channel to receive and guide the rod (2) of a piston (3). The component (1) acts as a guide for the rod and a support for at least two rigid (5, 5a) or spring-loaded (6, 6a) vanes which extend parallel to the lengthwise axis of the channel and along the sides of the container (8) to be crushed. The vanes can be smooth or have toothed inner surfaces, and they can have inner projections to interact with the piston, which incorporates a system for releasing air from inside the container as it is crushed. The piston can incorporate a tube which passes through it and projects from its lower end. The tip of the tube is cut at an angle so it perforated the top of a can as it is crushed. ADVANTAGE - More convenient to use in the home, allowing cans and plastics bottles to be reduced in volume for disposal.
