Abstract: Abstract of the disclosure.         This safety razor, mainly, consists of a handle mem-ber shaped like an arc of a parabola,  which acts, at one end, as the griping portion of the said safety razor.         Within the surface of the other end, a longitudinal base channel acts as fastening member of the handle member.         The exterior plate, assembled to the interior plate with the razor blade in between and in a flat position, is connected to the longitudinal base channel of the handle mem-ber by means of its fastening members.      The alternative use of both edges of the old fashion razor blade has been eliminated: the use of the traditional double edge razor blade is limited, always and only, to the use of one edge of the razor blade at a time, and, besides that, the blade edge makes an angle with the plane normal to the direction in which the safety razor is flowing.         The razor blade flows parallel to the face surface: in this way the cut of the beard is done by the safety ra-zor's blade at a 90° angle with the beard.

Abstract: ESCAPEMENT MECHANISM FOR TYPEWRITERS Abstract of the Disclosure Disclosed is a mechanism for replacing the non-escape-ment magnet normally utilized to inhibit escapement during certain machine functions on a typewriter.  A detent arm is connected to the normal pawl knock-off arm so that upon the print shaft rotating and effecting, by a cam thereon, movement of associated linkage and motion of the knock-off arm to disengage the pawl from the ratchet wheel, the detent arm associated with the knock-off arm detents the ratchet wheel and inhibits escapement thereof until the linkage and knock-off arm returns to its normal position by rotation of the print shaft.  Thus, if the escapement magnet coil is not energized, the pawl associated with the magnet will return to its normal position and the ratchet wheel will, because of the detent of the member associated with the knock-off arm, be inhibited from motion.

Abstract: ABSTRACT OF THE DISCLOSURE         A continuous mechanical ventilator system includes a ventilator known in the art with a pneumatic circuit connec-table to the patient and operating in the normal manner.  A bag and bag valve are interposed within the pneumatic connection such that when the valve is closed, the patient is on full as-sisted breathing from the ventilator.  When the bag valve is opened, gas from the ventilator passes into the bag from which it may be drawn freely by the patient in an unassisted manner.          Electronic controls provide means for varying the proportion of breaths to be assisted by the ventilator to the breaths from the bag which, of course are unassisted. The exhalation valve normally provided, is normally operatively connected to the ventilator in the usual way, when the device is in the assisted mode.  However, during the unassisted mode, the exhalation valve is isolated from the rest of the circuit so that no pressure pulses can be fed to the exhalation valve during this time.  By utilizing the bag and bag valve, both assisted and unassisted breaths consist of gas from the ventilator with the same amount of humidity and oxygen components.

Abstract: ABSTRACT OF THE DISCLOSURE A mobile apparatus for cleaning sewers, catch basins and the like includes a debris collection chamber mounted on the rear of a vehicular chassis.  A vacuum conduit communicates with the chamber and is adapted to be lowered into the sewer. A vacuum fan also communicates with the chamber and draws air through the conduit and chamber thereby picking up debris from the sewer.  As the debris enters the chamber, the configuration thereof creates a rapid decrease in the air flow velocity and otherwise interrupts the flow so that material entrained in the air is deposited in the chamber.  The configuration of the chamber also permits facile discharge of the debris out of the bottom of the chamber in that one end wall of the chamber is swingable to open the bottom thereof.  This same end wall also carries a hose reel for use in flushing the sewer.

Abstract: ABSTRACT OF THE DISCLOSURE          The present invention provides particular phenol/formaldehyde resoles which are especially useful as formable resins, and further provides cellular phenolic products having physical properties which are especially attractive for end-use application as construction foam. The resoles are characterized by a particular relation-ship between their viscosity and water content, expressed as the area bounded by certain points on a plot of resole viscosity on a logarithmic scale, as a function of water content of the resole, the particular area depending upon the mole ratio of formaldehyde-to-phenol at which the resole has been condensed. It has been found that phenol-formaldehyde resoles having the defined viscosity/water relationship are capable of providing phenolic foam having acceptable foam processability, a foam density from about 1.90 to about 3.70 pounds per cubic foot and, within this foam density range, a good balance of friability resistance and compressive strength. that is, a friability of less than 35 percent weight loss and a compressive strength of at least 20 pounds per square inch. Preferred resoles within the invention are foamable to phenolic foam having a reduced tendency to punk as well as the aforementioned desirable combination of foam processability and mechanical properties.
