Abstract: ELECTRIC FUSE HAVING TERMINAL CAPS AND  BLADES PROJECTING THROUGH SAID CAPS                       ABSTRACT A blade type fuse whose blades project through the end surfaces of the caps which close the tubular casing. Thus the blade contacts project from the outside of the casing into the inside thereof.  There are a plurality of fusible elements inside the casing, all having sub-stantially the same resistance.  Some of the fusible elements inside the casing that interconnect the afore-mentioned blade contacts have a relatively small spacing from the plane defined by the pair of blade contacts. Others of the fusible elements that interconnect the aforementioned blade contacts have a relatively large spacing from the plane defined by the pair of blade contacts.  All fusible elements are approximately equally distributed across the cross-section of the casing. This involves for some of the fusible elements a rela-tively large, and for others of the fusible elements a relatively small, spacing from the plane of the blade contacts to which their ends are attached.  To compen-sate for this difference in spacing the resistance of the connector means is approximately inversely propor-tional to the spacing of the fusible elements from the plane defined by the pair of blade contacts.  Thus the resistance of all fusible elements is equalized, irres-pective of their position across the cross-section of the casing of the fuse.

Abstract: INVENTOR:  ROLF RHUNKE            INVENTION: METHOD AND APPARATUS FOR OPENING MULTI-SHEET            PRODUCTS, ESPECIALLY PRINTED PRODUCTS     ABSTRACT OF THE DISCLOSURE            The printed product to be opened is moved with an open side thereof towards a stationary opening element.  The bottom part of the printed product contains at an open side, located opposite to a fold of the printed product, a marginal zone or portion by means of which the sheets of this bottom part protrude past the sheets of the other part of the product.          The opening element has an inclined deflector aligned with the protruding marginal zone extending parallel to the direction of product travel.  The printed product approaching the opening element is raised by means of a ramp prior to the leading edge of the protruding marginal zone or portion abutting against a deflecting face of the deflector.  By means of the deflector the sheets having the protruding marginal zone are downwardly deflected and thus are separated from the remaining sheets.  An opening is thus formed between the two parts of the product, and a support element arranged after the opening element enters this opening.  A retaining or hold-open member follows the support element.  The upper part of the product comes to rest on this retaining member, and the printed product thus is maintained in an opened state.
