Abstract: ABSTRACT OF THE DISCLOSURE           In a multi-stage bleaching system in which respect-ive bleaching chemicals are added to the stock in various stages, apparatus in which in the first stage in which chlorine is added to the brown stock, the first of a pair of sensing units associated with the stage comprises a source of red light directed onto the incoming brown stock and a suitable detector for sensing light scattered from the stock to produce a first signal representative of the brightness of the in-coming stock and the second similar sensing unit of the pair senses the brightness of the stock immediately following the addition of chlorine to produce a second signal.  The first and second signals are compared to produce a difference signal indicative of the change in brightness independently of the condition of the incoming stock and this difference signal is compared with a set point standard to provide a control signal for regulating the addition of the chlorine to the brown stock.

Abstract: ABSTRACT OF THE DISCLOSURE         An optical system for projecting an image of an object, operating between fixed object and image planes.  Both the object conjugate and the image conjugate are variable to vary the magnification in the system.  This is accomplished without moving the optical axis by means of a first roof mirror on the object side of the lens and a second roof mirror on the image side of the lens.  These mirrors each fold the optical axis by 90° and are movable along a locus at 45° to the optical axis to change the object and image distances.

Abstract: ROTATION REDUCER FOR POWER SWITCH ASSEMBLY     ABSTRACT OF THE DISCLOSURE      The disclosed device eliminates the undesired rotational movement of an installed in-line power switch of the type having a ribbed insulator through which an insulator rod is extended into metallic end fittings.  The end fittings carry the electrodes or contacts of a blade switch assembly and at least one of the end fittings is adapted for pivotal mounting to the clevis member end of a strain link.  The end fitting at the pivotal mounting is provided with integral projecting tongues which project away from the pivot axis and engage a surface of the clevis thereby to reduce the relative rotation between the end fitting and the clevis member about the pivotal mounting.  In one embodiment the tongue includes an inclined surface adapted to wedgingly engage a corresponding inclined surface of the clevis member in a complementary relationship therewith.

Title: Process for the production of a mixed-oxide oxidation catalyst containing vanadium and pentavalent phosphorus
Inventor: STEFANI GIANCARLO

Granted: 1980-03-11
Abstract: Abstract of the Disclosure The process for the production of a mixed-oxide oxidation catalyst which, based on vanadium and penta-valent phosphorus, has an atomic ratio of phosphorus to vanadium between 1.05 to 1 and 1.10 to 1.  The process involves reacting a salt of tetravalent vanadium, dissolved in a non-oxidizing acid aqueous solution, with ortho-phosphoric acid.  The resultant soluble vanadium salt complex, after concentrating the solution, is precipitated by adding water.  The precipitate is dried.  The dried precipitate is put or formed into the desired form.  The formed, dried precipitate is subjected to a heat treatment of at least 300°C.  A mixed-oxide oxidation catalyst is obtained, which may be used in the production of maleic anhydride.

Abstract: Abstract of the Disclosure A two-way transmission system, which utilizes solid state circuitry and a pair of opto-couplers, achieves high linearity and provides high electrical isolation between input and output signals without the use of the traditional hybrid transformer.  The opto-coupler consists essentially of a single light-emitting diode (LED), two light detector diodes (LDDs), and an operational amplifier.  The LED is connected to the output of the amplifier and is physically located with respect to the two LCDs such that light emitted by the LED impinges on the photosensitive areas of the LDDs. The first LDD is coupled to the input of the amplifier, and the second LDD is coupled to output circuitry.  This opto-coupler is relatively temperature insensitive and compensates for the inherent nonlinearity of an LED.  These characteristics facilitate the use of the above-described opto-coupler in systems which require relatively high linearity and temperature stability.

Abstract: ABSTRACT OF THE DISCLOSURE:     The neck of a plastic container of the type originally in-tended for use with a foil type closure is formed with a top bead, a first reduced-diameter step and a second reduced-diameter portion and then a downward-outward widening breast.  The cap has a top disk which seats on the neck and has an outer skirt having an internal upper bead engaging under the top bead and a second internal bead fitting deeply into the second reduced-diameter portion.  An inner skirt depends from the disk and fits inside the neck.  Thus the cap seats tightly on the container neck.  To remove the cap, a circumferential internal weakened portion is formed in the outer skirt.  A curved weakened portion extends up from the bottom edge of the outer skirt and merges with the circumferential weakened portion.  A pull tab depends from the bottom edge of the skirt.  By pulling upward on the tab, the portion of the outer skirt below the first reduced-diameter portion of the neck is torn away.  The remainder of the cap may be snapped off and later replaced for reclosure.

Abstract: ABSTRACT OF THE DISCLOSURE      Breathing apparatus is disclosed in which a selected portion of each exhalation is returned to the inlet side for rebreathing.  The percentage of each exhalation rebreathed varies from exhalation to exhalation and is determined in accordance with the detected magnitude of the preceding inhalation.          Breathing mixture is withdrawn by the user from a reservoir which is in communication with a cylinder having a spring loaded piston therein,  The pressure in the reservoir, and hence in said cylinder, at the end of each inhalation determines the position of the piston.  A chamber receives the exhaled breath and expands to a degree dependant on the position of the piston.  Once the chamber has expanded to the maximum extent permitted for that exhalation, the remainder of the exhalation is discharged from the apparatus.

Abstract: LIFT BRAKE FOR EXHAUST WATER FOR A VERTICAL   DRAIN PIPE SYSTEM            ABSTRACT OF THE DISCLOSURE        The invention relates to a lift brake for exhaust water capable of installation in a vertical drain pipe system.      In the vertical drain pipes of multi-story buildings, the speed of fall of effluent water can become very great, causing a partial vacuum which can lead to the emptying of the siphon drain traps of attached plumbing installations.      To prevent this from occurring, lift brakes have been installed at the lateral attachment location of the drain pipe on each floor, in order to dissipate at least part of the kinetic energy of the water.      For example, the branching members can be provided with water deflecting devices, and with auxiliary connections in the area of the lateral attachments.      Such branching members are naturally complex and expensive to produce, and can be placed only at certain locations in the vertical drain pipe system.      The object of the invention is to overcome these disadvantages and to provide a lift brake which is characterized by a tubular member having a surrounding bulge and a deflecting rib arranged on one side of its inner wall and partly projecting into the interior of the tubular member.  According to a preferred embodiment, the deflecting rib has a crescent shape and extends in a diagonally downward direction.

The applicator unit has a lower gripping portion which rotatably mounts an eccentric drive assembly which is drivingly coupled to the cable so as to be oscillated by cable rotation.          An elbow-shaped tube extends upwardly and outwardly from the eccentric assembly so that an application pad mounted on the outer end of the elbow is moved in a circular path around an axis extending parallel to the surface of a patient's body and also parallel to the surface of an application pad, which allows the pad to impart a percussive and a directional massage stroke when it is applied to the body.  The resultant force transmitted to the body has two components:  one perpendicular to the body to loosen congestive material, and one force component parallel to the body to mobilize congested material in a selected direction.
