Abstract: BOOKLET PREPARATION UTILIZING        AN ELECTROPHOTOGRAPHIC APPARATUS                      ABSTRACT            In an electrophotographic apparatus, a plurality of original sheets are copied onto a plurality of copy sheets in an order permitting assembly of multiple- sheet booklets.  The originals are presented to an automatic document feeder by an operator in one order which repeatedly presents the originals to the copier for reproduction in another order. The copies are reduced in size and placed adjacent each other onto both sides of sheets of copy paper in a sequence facilitating booklet assembly.  Initially the originals are loaded into the automatic document feeder with the lowest numbered original page presented to the copier first. Odd-numbered originals are copied onto successive halves of copy sheets.  When half of the originals have been copied, the copies are reloaded into the copier to permit copying of odd-numbered originals onto halves of the backs of the same copies.  Thereafter, the originals are restacked in reverse order with the last-numbered page presented to the copier first, and the copies are reloaded.  Copying is completed by copying the even-numbered originals onto the remaining halves of the copies, in the same manner as the odd-numbered originals, to give a completed booklet.  Copy operation may be facilitated by the use of a recirculating document feed in place of the automatic document feed, rotation of originals or copies during the reloading/restacking operation or double exposure of the copies.  Duplexed originals may be used in place of originals having images on one side only.

Abstract: A STRESS SENSOR PARTICULARLY SUITABLE FOR ELASTIC, PLASTIC AND VISCO-ELASTIC MATERIALS              Abstract of the Disclosure A cylindrical stress sensor has a case that is long relative to its diameter.  The case may be completely imbedded in the body of a host material in which a change of stress is of interest.  That portion of the sensor which is imbedded has a rounded end.  The rounded end, circular cross section, and relatively large length-to-diameter ratio avoid errors occasioned by stress concentration.  A strain transducer of a vibrating wire excited by a magnetic coil is located remote from any imbedded end of the sensor.  Changes in strain on the wire alter the frequency of the wire.  This change in frequency is picked up by the excitation coil as a signal.  A stacked, three-transducer array, with the wire of each transducer at 45° from a neighboring transducer, can detect changes in the magnitudes and directions of the principal stresses, without first establishing the direction of the primary or secondary principal stress.  The effective Young's modulus of the sensor is large relative to the host material, being at least equal to, or greater than, four times the latter's modulus.  The distance from a transducer to an end of the sensor to be imbedded in the host is sufficient to avoid erroneous signals occasioned by end effects of the case, and is usually at least ten radii.

Abstract: ABSTRACT:    Method of manufacturing a colour selection elec-trode for a colour display tube in which patterns of aper-tures are etched in a comparatively hard steel foil by means of a photoetching process.  Mask blanks are cut from the steel foil, each mask blank having a pattern of aper-tures.  In order to soften the mask blank in behalf of the subsequent deep drawing the mask blanks are annealed in a furnace.  In order to obtain a good magnetic screening by the shadow mask a grain size of the mask material between 0.015 and 0.040 mm with an average grain size between 0.020 and 0.030 mm is necessary.  In order to obtain this grain size the mask blanks must be annealed at a tempera-ture from 600°C to 850°C which lies above the temperature at which the mask blanks may adhere together by thermo-molecular welding.  In order to prevent rejects as a result of this welding, a stack of mask blanks is laid on a curved substrate prior to annealing, which substrate preferably has the form of a part of a cylinder the radius of which is equal to the radius of the mask after deep drawing.  After annealing in a furnace the mask blanks are placed on a flat substratum in which the thermomolecular wells present are interrupted without damaging the mask blanks.  By annealing on the substrate the mask blank engages substantially the mould during deep drawing so that no deformations of the mask blank occur during the deep drawing process.     .

Abstract: 22,826 Abstract of the Disclosure A movable contact is adapted to engage with and dis-engage from a fixed contact within a circuit breaker housing.  A contact arm, coupled to the movable contact, is caused to trip when appropriate means are actuated. The invention resides in apparatus for actuating such means including a ferromagnetic material armature latch partially rotatable about a housing axis.  The latch has a first retaining means and a first coupling surface.  A latch member, partially rotatable about a housing axis, has a second retaining means and a second coupling surface adapted to couple with the first coupling surface.  Fur-ther, the latch member is adapted to recouple the second coupling surface subsequent to it becoming uncoupled from the first coupling surface.  A spring couples the two re-taining means.  An electrical circuit, including the con-tacts, is responsive to an overload current through the circuit breaker for causing the armature latch to par-tially rotate, uncoupling the two coupling surfaces, whereupon the spring causes the latch member to rotate with an impetus, actuating the coupled means, thereby tripping the contact arm and opening the contacts.

Abstract: ABSTRACT OF THE DISCLOSURE   An hydraulically operated impact motor, for example a jack hammer, has a hammer piston (12) with a single land (18).  The hammer piston surfaces (19, 20) of the land (18) form two cylinder chambers (21, 22) together with the cylinder of the piston.  The rear cylinder chamber (21) is constantly pres-surized by the pump pressure and the front cylinder chamber (22) is periodically pressurized and drained by means of a valve (28).  The valve (28) is controlled by two control passages (32, 41) that have ports (33, 34 and 47-50 respectively)into the cylinder and conveys the control pressure to valve shifting piston surfaces (30, 39). The larger one (39) of the valve shifting piston surfaces (30, 39) is the end surface of a plunger (36) and an intermediate chamber (35) is formed between the plunger (36) and the valve spool (28). The intermediate chamber (35) is constantly pressurized through a passage (54).  Internal leak passages (52, 55) in the valve spool makes the valve spool stable in its two positions.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention provides a retainer clip for holding the backing member of a windshield wiper blade or squeegee assembly against longitudinal movement in the claws of a superstructure in which it is mounted.  In one embodiment a claw-like body has a resilient tongue formed on its upper wall by two parallel slots, the tongue having on its underface a projection that cooperates with a cut-out in the backing member to retain them against relative movement.  A longitudinally-extending transverse flexible integral arm has a hook portion at its end that can embrace   superstructure mounting claw, so that the claw is trapped between the clip body and the hook portion against longitudinal movement, and the backing member is thereby retained in the superstructure.  A preferred backing member is provided with a number of the above-mentioned cooperating recesses spaced longitudinally from one another, each of which is designated to make the combination suitable for a replacement wiper blade assembly of a different size and/or a different manufacturer.  In an alternative clip structure two opposed hook portions are provided for claw embracement by a thin metal U-shaped member that is interposed between the clip body and the backing member.
