Inventor: TERHO KARI A
IPC: B65G47/82
Filed: 1989-11-22
Abstract: This publication discloses an apparatus for loading and unloading objects, in particular cylindrical objects, on a continuously operating carriage conveyor. The apparatus comprises a fixed frame (3) and a lift platform (4), which are connected by arms (6, 7, 8) to each other so that one end of each arm is attached to the frame (3) while the other end is attached to the lift platform (4). When the lift platform (4) is pulled with the help of a hydraulic cylinder (16), the arms (6, 7, 8) are rotated and the platform (4) is shifted both horizontally and vertically. An advantage of the apparatus in accordance with the invention is that the object to be loaded reaches an equal speed with that of the conveyor carriage (2) at the time the object touches the carriage (2).

Title: Shear for shearing laminar elements, or the like
Inventor: PARIGI MARCELLO
IPC: B23D19/04
Filed: 1990-01-16
Abstract: "SHEAR FOR SHEARING LAMINAR ELEMENTS, OR THE LIKE"          Abstract The shear      for shearing laminar elements      or the  like  comprises a pair of  blade-holders, which, during the shearing operation, are stressed by two forces (Fx and Fy) perpendicular to each other and having as their resultant,  the force FR.  At the shearing time, both  of said blade-holders           are supported in an inclined position,  so that their main axes        come to  coincide with the direction of said  resultant  force (FR).  From  the above,  the possibility results that the mass of the inclined blade-holder can be reduced even  by 50%  relatively to the mass of a traditional blade-holder which  is  not inclined,  without the stiffness  of  said blade-holder,  relatively to the shearing  forces,  being endangered.     The  invention can be applied as well to  quillotine shears  and  to  rotary shears       equipped  with  roll blade-holders.

Title: Die cut disposable grounding wrist strap
Inventor: KLEPEL DONALD E
IPC: H05F3/02
Filed: 1990-09-05
Abstract: An inexpensive grounding wrist strap and tether for draining excess electrostatic charge, which may be used once and then disposed. The strap and tether are formed integrally and include a conductive strip having a discrete resistance portion for safety considerations.      The discrete resistance portion is formed by making a zig-zag pattern of cuts in the conductive strip, thereby increasing the length of the current path through the discrete resistance portion. Due to the slight resistivity of the conductive strip, the lengthened current path results in a discrete resistance being built into the strip. The cuts may be made in the strip at the same time the strip is fashioned out of a sheet of the conductive material, such as carbon loaded polyethylene.
