Abstract: ABSTRACT OF THE DISCLOSURE       A probe immersible in liquid having oxygen dissolved therein and adapted to continuously and accurately measure the oxygen concentration.  The probe includes a noble metal measuring electrode, a copper counter-electrode and a potas-sium hydroxide electrolyte which together define a galvanic cell whose output current depends on the amount of oxygen passing into the cell through a diffusion membrane permeable only to gases.  The oxygen within the cell is electrochemically reduced at the surface of the measuring electrode to generate a current that is proportional to the oxygen concentration, the counter-electrode being oxidized.

Abstract: BELT-TYPE SANDER ATTACHMENT  FOR PORTABLE POWER DRILLS       Abstract of the Disclosure A portable belt-type sanding device adapted for use as an accessorial attachment to a portable hand-held power drill.  The sander comprises a pair of laterally spaced rollers rotatably mounted within an open-bottomed elongate body member with a bearing plate interposed between the rollers and attached to the body member to provide a firm backing for the operative portion of a sanding belt looped around the two rollers.  Provision is made for coupling the power drill directly to a drive axle of one of the two rollers, and the driven roller and its drive axle are offset from the plane of the bearing plate a perpendicular distance sufficient to prevent the coupled drill body from contacting a work piece against which the bearing plate is pressed as the sander is being operated.  A handle adjustably attached to the top of the body member may be positioned on either side of a line through the longitudinal center of the body member to facilitate grasping the sander with either hand while holding the handle of the power drill in a manner permitting manipulation of its on/off switch with the other hand.  The bearing plate providing the supportive backing for the oper-ative portion of the sanding belt is of sufficiently small size to permit the sander to be powered by a relatively low-power drill without danger of overloading the drill motor.          Provision is also included for selectively mounting the sander on a work table with the plane of its bearing plate oriented either vertically or horizontally.

Abstract: APPARATUS AND METHOD FOR NEUTRALIZING STATIC             CHARGES IN SHEET/WEB FEEDING DEVICES     Abstract of the Disclosure A corona and associated  electrical drive as shown herein, neutralize the static charges on non-conductive sheets or webs.  The neutralization of static charge is accomplished by passing the  material to be neutralized under a double  wire corona.  Both wires  in the corona are connected  to an AC  signal.  The AC  signal drives both wires with a signal that alternates in polarity at frequency   f.    The   wires  are   spaced   apart   a predetermined  distance  calculated   from  a  function dependent upon the frequency of  the  AC signal and the speed of the paper moving  under the corona wires.  The predetermined distance is such that a given area of the paper will pass under one wire  at a first polarity and under  the  second  wire   at  the  opposite  polarity.    Further   enhancement   of    neutralization   can   be accomplished by using  a second double wire  corona out of  phase  with  the  first  double  wire  corona.   In addition  the sheet  or  web  as  it  passes under  the corona wires is supported to prevent static  charge on the support from balancing a static charge on the sheet or web.  Accordingly, the only static charge present as the sheet or web moves under  the corona is that charge carried by  the sheet  or web.   The corona  wires will neutralize that  charge either by discharging  it with oppositely  charged  ions   or   depositing  oppositely charged ions to balance the charge already on the sheet or web.  Thus  as the sheet or web moves  away from the neutralizing station the sheet or  web has a net charge which is substantially zero.

Abstract: Dispositif d'autorisation et de blocage ou freinage d'un mouvement relatif entre deux pièces en fonction de l'importance de la perturbation provoquant ce mouvement.  Ce dispositif comporte un bâti ou un boîtier relié à l'une desdites pièces, un élément relié à l'autre pièce et susceptible de coulisser à travers ledit boîtier sans rotation par rapport audit boîtier, un élément rotatif susceptible d'être mis en rotation par le mouvement du premier élément pour permettre ce mouvement et de bloquer ou freiner ledit mouvement lorsque la rotation est empêchée ou freinée lorsque la perturbation présente une ampleur suffisante, et des moyens pour bloquer ou freiner ledit élément rotatif après une course faible ou nulle de l'élément coulissant.  Par course faible, on peut entendre une course par exemple de l'ordre de 0,1 à 0,5 mm.  On comprend donc que dès que  la perturbation présente une ampleur, F exemple par sa vitesse ou par son accélération, telle que l'actionnement du dispositif doit être provoquée, le dispositif réagit pratiquement instantanément sans permettre un mouvement notable de l'élément par rapport au boîtier.

Abstract: ABSTRACT OF THE DISCLOSURE           A clock has a clock face formed on the surface of a solid   revolution, e.g. a sphere, a cone or a cylinder.  Clock hands extend around the clock face following a helical path, and time-indicating markings are arranged on all the surfaces of the face.  It is therefore possible for a complete set of these mark-ings to be seen from any direction relative to the clock face.          The hands are normally driven by a conventional clock movement, there being an hour hand and a minute hand.  However, it would be possible in some applications to have only a single hand, e.g. a minute hand, and to drive the clock face relative to the hand.          The markings are arranged along helical paths, corresponding to the helical shape of the hands.

Abstract: ABSTRACT OF THE DISCLOSURE          A copy distribution system for sorting copies of document information in a stacking mode a regular collating mode or a special collating mode where different numbers of copies are distributed to sorter bins at the option of a machine operator.  A programmable device settable by the machine operator enables distributing sheets in different modes of operation.  In the special collating mode logic counts the copies advanced along a transport path until the selected count including zero has been satisfied and a signal is then supplied to an index motor which mechanically opens and closes the gates to the bins.  Upon energization of the index motor each of the gates opens and closes in a predetermined order until distribution to all of the bins has been satisfied in accordance with the setting of the programmable device,  In the regular sort mode of operation each of the gates is opened and closed in sequence after one copy sheet has been received in each of the bins and the operation is repeated for the preselected copy distribution in each of the bins.  For the stack mode of operation only one bin receives all the copy sheets.
