Abstract: This invention relates to a method for filling particulate material in vertical tubes (1) where the velocity of fall of the material (4) is reduced by having it glide down a rotating spiral duct (2) or by gliding down a rotating inner tube (5) with openings above the bottom (6) through which the material can fall out. The inner tube (5) is filled with the particulate material (4). After the material has fallen out of the spiral duct (2) or the inner tube (5), it can fall towards the tube~s (1) wall during the drop onto the top layer of filled material.

Patent CA-2516302-C (CA)

IPC: H03F1/32
Filed: 2004-04-09
Granted: 2013-12-17
Abstract: An RF power amplifier circuit for amplifying an RF signal over a broad range of power with improved efficiency includes a carrier amplifier for amplifying an RF signal over a first range of power and with a power saturation level below the maximum of the broad range of power is disclosed. One or more peak amplifiers are connected in parallel with the carrier amplifier with each of the peak amplifiers being biased to sequentially provide an amplified output signal after the carrier amplifier approaches saturation. The input signal is applied through a signal splitter to the carrier amplifier and the plurality of peak amplifiers, and an output for receiving amplified output signals from the carrier amplifier and the plurality of peak amplifiers includes a resistive load R/2. The split input signal is applied through a 90~  transformer to the carrier amplifier, and the outputs of the peak amplifiers are applied through 90~ transformers to a output load. When operating below saturation, the carrier amplifier delivers power to a load of 2R when the carrier amplifier delivers current to the load, which is one-half the current at maximum power and the amplifier is saturated. The signal splitter can split the input signal power equally among the carrier and one or more peak amplifiers, or the input signal can be split unequally with the carrier amplifier receiving less input power than each of the peak amplifiers and vice versa.

Title: Shock resistant mounting for small display screen
Inventor: CHEN CHAO
IPC: H04B1/38
Filed: 2005-08-31
Granted: 2009-12-22
Abstract: The display screen unit of a cell phone or PDA is carried in a mounting frame, which is bolted into the casing. The screen unit is sandwiched between cushioning layers of foam. The screen unit can move laterally, relative to the mounting frame, putting the foam in shear, in response to an edge or corner impact. Springy tabs are bent up from the metal backing plate of the screen unit, and these springy tabs serve to cushion the impact of the screen unit against the mounting frame, in response to the edge or corner impact, leading to a marked improvement in drop test performance. As a production-line benefit, the springy tabs also permit the screen unit to rest on the lip of the mounting frame, enabling the screen unit to be accurately positioned in the mounting frame just before the screen unit is finally pressed down into contact with the securing adhesive.

Abstract: A method of intensive continuous fire refining of copper is provided. The method includes continuous tapping in of liquid copper into an oxidation reactor.  Liquid copper is oxidized with combustion gases containing oxygen or with air. Simultaneous with the oxidizing, slag is formed that collects impurities. Oxidized copper and slag are continuously tapped out from the oxidation reactor, with continuous tapping in of the oxidized copper in a reduction reactor. Oxidized copper is reduced using carbon and reducing gases formed by a partial combustion of fuel and carbon. Reduced copper is continuously tapped out from the reduction reactor. Liquid copper is dispersed by gravitational flow through a packed bed of ceramic grains or other chemically neutral grains, and the liquid copper is oxidized with counter-current flow of gases containing oxygen. The method therefore achieves the continuous fire refining of copper using gravity flow of liquid copper through two reactors in series, while introducing the flow of liquid copper through the packed bed in conjunction with a countercurrent flow of oxidizing gases.

Abstract: An amplification circuit that enables a network amplifier to amplify multiple mobile telephone signals transmitted at different frequencies. The amplification circuit includes a first diplexer which receives a first signal having a first frequency band and a second signal having a second frequency band. The first diplexer generates a combined signal containing both the first and the second signals.
