Title: A dust collector
Inventor: NISHIYAMA SHINROKU
IPC: B01D46/24
Filed: 1983-02-10
Granted: 1986-10-16
Abstract: The dust collector is for removing dust from a gas. The contaminated gas is drawn into a filter chamber (8) where it passes through hollow, flat, box-like, cloth covered filter members (7) and into gas passages (9 min ). Dust is separated from the gas by the filter members and at least some of this dust builds up on the outer surfaces of the filter members thereby gradually reducing their efficiency. To dislodge this built up dust compressed air is introduced into the filter members through outlets (11) thereof from compressed air outlets (12) disposed in the gas passages. In order to make this possible with a small capacity compressor, an outlet (14) in the gas passage is closed and an atmospheric air inlet (15) in the gas passage is opened by a piston and cylinder unit (16, 17) which operates respective valves (18, 19) when the compressed air is introduced into associated filter members. Only those filter members associated with one of the gas passages are cleaned at a time so that the collector can continue with its dust removal operation during this cleaning process.

Title: Surgical dressing
Inventor: RAWLINGS DAVID ALAN
IPC: A61L/
Filed: 1983-09-27
Granted: 1987-07-09
Abstract: A moisture vapor permeable, adhesive surgical dressing is described which comprises a continuous film of a hydrophilic polymer which has a moisture vapor permeability which is greater when in contact with water than when not in contact with water and which is attached around its edges to a water transmitting film so as to form a sealed portion into which exudate may pass from an exuding wound. The water transmitting film comprises a backing layer and an adhesive layer on the side remote from the continuous film. The adhesive layer is suitable for adhering the dressing to the skin. The water transmitting film allows or is adapted to allow access of water to the film when in contact with water so that when used on an exuding wound the high moisture vapor permeability of the continuous film allows water to evaporate through the dressing and prevents the dressing forming a blister. The low moisture vapor permeability of the film when not in contact with water makes the dressing suitable for use on non-exuding wounds. Preferably a second water transmitting film is present between the continuous film and the water transmitting layer.

Granted: 1987-10-15
Abstract: A bib (20) having a neck-accommodating aperture defined by a segmented perimetric edge: ie, a segmented neck-aperture perimeter. The neck-accommodating aperture (43) is generally oval-shape and the sheet material from which the bib is constructed has a plurality of bifurcations such as slits (28) or notches which extend generally radially outwardly from the perimetric edge of the neck-accommodating aperture.

The petals (27) are radially conformable to a range of neck sizes and will, due to inherent resilience of the bib material maintain a comfortable fit even during infant neck contortions. In an exemplary embodiment, the distal end portions of such petals (27) are doubled under and have their distal ends secured adjacent their proximal ends, to obviate raw cut edges of such portions from contacting users' necks.

Abstract: The counter-balancing device incorporates a rigid auxiliary component hinged about a second horizontal axis parallel to the rotation axis of the robot arm. This auxiliary component incorporates two transverse arms whose distal ends are capable of bearing against a portion of a component which is movable in translation and is subjected to a return force proportional to the distance between an initial position and the position instantaneously occupied by this component. The rigid auxiliary component is driven in rotation about the second axis at an angular velocity whose modulus is equal to half that of the robot arm; the assembly is calibrated angularly in such a way that when the arm is vertical, the two distal ends of the transverse arms bear simultaneously upon the said straight portion, the constant of proportionality between (a) a return force and (b) the amplitude of displacement and the distance from the second axis to the distal ends of the transverse arms being chosen in such a way that balancing is obtained.
