Abstract: METHOD FOR MAKING ZINC ELECTRODES FOR ALKALINE-ZINC BATTERIES                            ABSTRACT           A method for making zinc electrodes for alkaline-zinc batteries comprising the steps of:  mixing an amount of a zinc-magnesium binder alloy with an amount of a material chosen from zinc and a second zinc-magnesium alloy to form a mechanical mixture.           The melting temperature of the material is at least 15 Celsius degrees higher than the melting temperature of the binder alloy.  The mixture is applied to a current collector and the current  collector  with  applied  mixture  is  heated  to  a temperature at which incipient melting of the binder alloy causes  sintering of  the mixture with  the  formation  of  a coherent layer solidly bonded to the current collector.  The compositions and the amount of the binder alloy and the second alloy are selected such that the active material in the layer of the electrode contains no more than about 15% magnesium, preferably no more than about 10% magnesium.     In various embodiments, a binder alloy containing 45% to 55% Mg is eutectically sintered with zinc or a second alloy containing from > 0% to about 10% Mg, a binder alloy containing about 3% to 4% Mg is eutectically sintered with a second alloy containing either about 20% to 43% Mg is eutectically sintered with a second alloy containing either about 20% to 43% Mg or about 52% to 80% Mg, and a binder alloy containing either about 41% to 50% Mg or containing about 1.5% to 3% is eutecticly sintered with zinc.

Abstract: Abstract of the Disclosure A substantially one-piece ladder attachment is disclosed.  The attachment provides a secure, laterally well-supported platform on which a worker would stand.  The invention is particularly useful for an extension ladder, especially one with circular rungs.  The attachment of the invention comprises a platform having a single, preferably hollow, vertical support member projecting adjacent one edge thereof.  The vertical support is centrally disposed on the edge on which it is located.   The vertical support angularly projects  from  the platform and  is  connected to  an  arcuate, horizontally disposed, transversely mounted upper bracket.   The upper bracket is intended to engage the rung of a ladder to impart lateral stability to the platform.  The attachment further includes a lower, horizontally-disposed, arcuate bracket which is located on the same edge of the platform as the vertical support.  The lower bracket is intended to cooperate with a second rung of a ladder to provide lateral, as well as, vertical stability to said platform. In a preferred practice of this invention, grip means are adhered to the top of the platform.  In a further preferred practice of the invention, a rung security means, such as a key, is mounted in said upper bracket  and through the  support member to  secure  the attachment to the ladder.

The front and rear frame parts are  interconnected rigidly at and above the press roll combination by means of a rigid intermediate frame part.  The intermediate frame part operates as the frame part of the tensioning device of the first upper fabric, and the intermediate frame part together with the upper fabric tensioning device and the tensioning roll.  The intermediate frame part may be pivotally connected to the front frame part by means of horizontal articulated joints, or shifted to the side substantially linearly, so that at and above the press roll combination a free open space is opened.  This space can be utilized in replacement both of the upper press rolls and of the upper fabrics.

Abstract: In an electronic imaging system in which a document is electronically imaged on a platen by a scanning electronic imager, a document for which manual handling is desired is manually positioned in a special manual registration position on the platen in which one corner of the document underlies a unique signal generating optical indicia positioned over that cornerof the platen. Preferably, this optical indicia is a uniquely numbered bar code pattern on a stationary baffle, or other overlying surface, upstream of the document feeder platen transport, and preferably located in a start of scan area. The electronic imager is at least partially optically occluded from reading thatunique bar code pattern by a document present in that manual registration position. (A document for which automatic feeding is desired may be placed in a document feeder and fed thereby onto the platen into a different registration position in which no portion of that document is interposed between that bar code and the imager.) The imager can read, or not read, that unique bar code to provide a unique control signal to control the document feeder and/or provide other desired functions, such as indicating that a previously manually placed document was left on the platen.

Abstract: PULSED ELECTROMAGNETIC FIELD DETECTION SYSTEM                 ABSTRACT OF THE DISCLOSURE Apparatus and method for avoiding deleterious effects on cardiac pacemakers while detecting the presence of electromagnetic markers in an interrogation zone of an electronic article surveillance system.  It has been found that pulsing the magnetic field in an interrogation zone avoids problems associated with the interference of the functioning of cardiac pacemakers.  The field in the interrogation zone is maintained at a low level until the presence of an individual is sensed in the interrogation zone.  Upon such sensing, the energy level of the field is raised for a period sufficiently long to the detect the presence of a marker, but not long enough to seriously interfere with the functioning of a pacemaker. The system will remain at a low level thereafter for a sufficient period so as not to adversely affect a pacemaker wearer who is in the vicinity of the system.
