The neck-accommodating aperture is generally oval-shape and the sheet material from which the bib is constructed has a plurality of bifurcations such as slits or notches which extend generally radially outwardly from the perimetric edge of the neck-accommodating aperture.

In an exemplary embodiment, the distal end portions of such petals 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.

A photovoltaic cell comprising gallium arsenide is produced in a self-supporting thickness by conventional methods. A pattern of contact lines and a bus contact are formed on the front surface of the cell and a transparent coverslide is bonded thereover.

Abstract: A focal plane array including a first integrated circuit for infrared radiation (IR) detection and a second integrated circuit for signal processing is assembled in a flip-chip structural configuration. Each integrated circuit includes an array of metallic contacts on a surface thereof for interconnection in the flip-chip arrangement. The contact array of the IR detector includes a substantially greater number of contacts than the contact array of the signal processor. Consequently, it is not a prerequisite to precisely align the two integrated circuits in a one-to-one contact relationship for the flip-chip bonding operation therebetween. Thus, each metallic contact of the signal processor may be roughly aligned and bonded to a corresponding group of metallic contacts of the IR detector array without altering significantly the operation of the overall focal plane array as long as at least one metallic contact of the IR detector array is included in each corresponding contact group.

Abstract: An air-directing device for directing air to the multiple cylinder dryer of a paper machine includes members for blowing dry air into the vicinity of the web at those points where the evaporation of water from the web is strongest. This reduces the humidity in such regions and promotes the evaporation of water from the web. The points are the initial parts of the cylinder intervals after contact with the web. The air-directing device is so placed, and its air-blowing members are so disposed and directed, that the air blown out from such members is directed into the clefts defined by the surface of the drying cylinder and the paper web. This achieves a pressure effect in the clefts. The air-blowing members are primarily used in connection with single fabric conduction in pockets on the side of the web to urge the web fast to the fabric and are preferably disposed on a doctor beam or in conjunction therewith.
