Patent EP-0377952-A3 (EP)
Title: Improved apparatus for cleaning air in coal mines
IPC: B01D46/00
Filed: 1989-11-16
Abstract: The apparatus includes a large-capacity main 
blower (47) for drawing in air from the face of coal being 
mined. The main blower draws the air sequentially through a 
grid (20) which deflects large pieces of coal into a refuse 
bin (32), and a main stage of centrifugal filters (26) which 
separates dust and particles into a stream of dirty air 
while discharging the clean air back into the mine. The 
dirty air is routed through a secondary stage of centrifugal 
filters (65) which is energized by a second blower (72) or 
pressure unit, the output of which is then routed through a 
cloth filter stage (76). Only clean air is discharged into 
the atmosphere. An air balancing device (95) maintains 
proper operating pressures in the secondary filter stage for 
more efficient processing of the dirty air discharge. An 
adjustable balancing gate (35) maintains proper operating 
pressure at the collection outlets for the main and 
secondary filter stages. A device (105) is also included 
for incorporating rock dust into the main clean air 
discharge using the power available at the main blower to 
reduce any hazard.

Title: Ventilating fan for fire fighting
IPC: F04D25/04
Filed: 1990-02-06
Abstract: A manhandleable ventilating fan assembly (10) has a set of fan 
blades (36) carried by a fan hub (34) secured to the front end 
of a shaft (16) rotatably mounted in a housing (22) for a 
water-driven turbine runner (20) having radial-flow turbine 
vanes (20′) on its rear face. The turbine housing has 
rearwardly-facing inlet and outlet connections (24 and 26) for 
fire hoses, the inlet leading into an inlet chamber having a 
control valve (60) through which water passes to a volute (46) 
supplying the turbine vanes (20′) and having a diameter no 
greater than that of the fan hub (34). Water mist can be 
added from nozzles (70) to air driven by the fan. The 
assembly is tiltably mounted on a frame (93) supportable on 
wheels (100). A by-pass circuit may bleed off and replace 
some of the water circuitry through the turbine, and a driving 
pump on a fire truck, to avoid over-heating.

Title: Perceptually-adapted image coding system
IPC: H04N19/94
Filed: 1990-04-30
Abstract: An image-coding system reduces image data redundancies and 
perceptual irrelevancies through progressive sub-band coding. The 
image is separated into plurality of sub-bands ((0,0) to (3,3)). 
From this sub-band information, a perceptual metric, based on the 
properties of the sub-band filters, quantizer error distribution, 
and properties of the human visual system, is determined (28) which 
provides the maximum amount of coding noise that may be introduced 
to each pixel in every sub-band without causing perceptible 
degradation of the coded image. This perceptual metric is used to 
adjust the quantizer (25) used in encoding each sub-band signal. In 
addition, redundancy in the output of the quantizer is reduced using 
a multidimensional Huffman compression scheme (27).

Abstract: An improved adhesive mounted nutplate 
assembly (10) and related installation method are provided 
for secure mounting of a nutplate (12) or the like onto a 
substrate, particularly at a blind side of the 
substrate in alignment with an access opening. The 
nutplate assembly includes a nut member (14) having a 
resilient fixture pin (16) received therein, with the nut 
member (14) being adapted for adhesive mounting onto the 
blind side of the substrate with the fixture pin (16) 
extending through the access opening. A pulling 
force applied to the fixture pin draws the nut member 
with a positive force against the substrate. The 
fixture pin is sized to bind within the access 
opening when released to maintain this positive force 
for the duration of an adhesive cure period, after 
which the fixture pin can be forcibly drawn through 
and removed from the nut member. A preferred nut 
member comprises a nutplate (12) having a floating nut 
carried by a base (18) which is adapted for adhesive 
mounting onto the substrate. An improved adhesive 
applicator is also disclosed.

Abstract: The present invention relates generally to a ciagrette substitute for administering a dose of nicotine. More specifically, the present invention is directed to a nicotine-containing dosage-form comprising a holder member which may be used as part of an effective smoking cessation program or in situations where smoking is undesirable or not permitted. The dosage form is configured as a dosage form having a nicotine-containing composition attached to a holder member. Nicotine is released from the dosage form and absorbed through the intra-oral mucosal surfaces as the nicotine-containing composition releases nicotine within a user's mouth. The holder member facilitates insertion and removal of the dosage form into and out of a user's mouth. The user can selectively insert and remove the dosage form as desired to selectively control the release of nicotine. In addition, the user can insert and remove the dosage form in a manner which meets the user's psychological need or desire for ritualistic oral stimulation similar to cigarette smoking.
