the" nose; To overcome this" difficult the face-engaging annulus'between-its' veryiiexilile-inner'andouter marginsds made stiffrelativet'o the connection between the annulus and mask body, so that pressure on theannulus atone side of the connection result-in flexure' ofthe connection. Thus; in application of the mask,.if at some radial sector. one side of the annulus is'pressed" against tlieface before the other side contacts the=-face;theconnection between that radialssectorof the annulus andthe-mask body will flex hinge-like,-,allowing the annulus to rock or pivot about the connection to carry the unenga'ged'side of the annulus into contact with the face.
In Fig; l-the face-engaging annulus.10 is providedwith such an outer portionor. flange. In. the form selected for illustration, the outerflange'40; like the inner flange 13 is tapered in.the. direction away from the connection 19 to the maskbody" A. region 41- near the' connection 19 is readily deformable both axially and transversely but opposes circumferential stretching. Another region 42 at the outer area of flange 40 tapers to a thin membrane, is very flexible axially and is easily stretched circumferentially for sealing engagement with the face.
The regions 41 and 42 of the outer flange 40 correspond in function to the regions and 14, respectively, of the inner flange 13. That is, the region seals against the face when held in contact to the face by bending or folding of the region 41 in response to force applied thereto through the mask body 11 and connection 19. p The flanges 13 and 40 diverge toward the face and are connected at their juncture 43 so that the annulus 10 is V-shaped in cross-section. When both flanges of the annulus 10 engage the face further pressure will force out air trapped between them and the annulus will tend to act as a suction cup.
I 'n Fig. 1 thes'e me'ans take the form of radially spaced longitudinal grooves inzthe face-engaging. annulus 10in the surface of theannulus oppositethe face; As best illustrated in Fig. 3,. one set of grooves 45 is formed in theinne'r flange 13' to leave ribs andanother set 45a is formedm the outer'flange 40 to leave ribs 71. The groovesextend entirely around the annulus both flanges" and-- advantageously. become progressively deeper in the direction toward the connection 19'.
If preferredgthe hinge-like action at the mask-bodyflange conn'ection 19 may be'enha nced by reducingthe thickness of' this connection as illustrated at' 19a in Fig.2 to" increase flexibility at the connection.

The head 50 is a flap which is normally held closed by its elasticity and that of the hinge connection 51, but which, when the shut-off plug 52 is removed, will open in response to suction in the breathing chamber 21 to admit air through opening 46. When air dilution is not desired, plug 52 is inserted in opening 46 where it is retained in place by an enlarged section 53 and a corresponding depression 54 in the wall of seat opening 46.
illustrates how the sides of the face-engaging annulus and the mask body between the nose and chin are forced radially inwardly toward the cheeks so that the mask is generally oval-shaped, the region 14 of the inner flange 13 i being bulged toward the sides of the nose and into recesses around the mouth.
In certain applications of the mask the outer flange of the face-engaging annulus is advantageously omitted as illustrated in Fig. 10, and except that the flange grooves have been omitted for clarity, this mask is otherwise identical in structure and functionto the mask of Fig. l.
elastomer which will not absorb moisture, is easily cleaned and which. will not change its characteristics under extremes of heat and cold is preferred. A suitable synthetic resin, and particularly a silicone, has been discovered to work best, especially for aircraft use.
To illustrate specifically certain advantageous and preferred features of the invention, and particularly the relative flexibility and deformability of difierent parts of the mask, Figs. 1, 9, and IOare drawn to scale. All are drawn to the same scale in which the dimension X in Fig. 10 is 3.5 inches when the masks are formed of an elastomer, preferably a silicone, exhibiting a durometer hardness from to 60.

The lender’s target market is Millennials who haven’t been able to build their credit scores yet, and cosigners are usually the borrower’s friend or family member. However, you don’t need to have a cosigner if you meet the lender’s minimum requirements.
The most significant benefit of obtaining a loan through Backed is the lender’s low interest rates, provided your credit or your cosigner’s credit is high enough. Backed only issues loans to residents in a few states, though.
Minimum Requirements for a Personal Loan with Backed
The requirements to obtain a personal loan through Backed vary depending on whether or not you have a cosigner.
Without a cosigner, your credit score must be 660 or higher and you must make at least $18,000 per year in gross income. You also need at least a 6-month credit history.
If you have a cosigner, then you don’t need to meet any credit score, income or credit history minimums. The cosigner will need a credit score of 720 or higher.
Loan Options with Backed
Backed issues loans to residents of Arizona, Arkansas, Florida, New Jersey, New York and West Virginia. Loans start at $3,000 up to a maximum loan amount of $25,000, except in Arizona where the minimum loan amount is $10,000. The maximum in that state is still $25,000.
Loan terms range from 1 to 3 years, and the APR ranges from 2.9 to 16 percent, making the interest rates with Backed potentially lower than most other personal loan options. After Backed approves you for a loan, it takes between 2 and 4 business days to receive the money.
Fees and Penalties
Backed has an origination fee between 0.8 and 2 percent depending on how they grade the borrower or the borrower’s cosigner. There’s no prepayment fee, and Backed provides a 15-day grace period for missed payments before charging a $20 late fee. There’s a $15 fee if your payment is unsuccessful, and a $10 fee for processing personal checks.
The Application Process
Backed using a grading system, basing the APR for your loan on the grade it assigns you as a borrower. At the beginning of the application process, you must provide Backed with information about your income, current debts, education level and how you plan to use the loan. The lender will then assign you a grade and provide you with an initial loan quote.
You can lower the APR on your loan by disclosing more information about yourself. Connecting a Facebook account helps Backed verify your identity, a LinkedIn account can support your employment history and education level, and a bank account provides more of your financial information, so all of these can result in a lower APR.
Of course, you can also lower your APR by adding a cosigner, and Backed says that this can result in up to a 41-percent APR reduction. The standard process is to add your cosigner when you apply for the loan, but you can also do so after you obtain a loan. If you add a cos
