IPC: B65D75/66
Filed: 1993-10-22
Abstract: ABSTRACT OF THE DISCLOSURE    A package consisting in an article packaged by a packaging film exhibiting heat shrinkability is disclosed.  The packaging film has its wrapping terminal end formed with a protuberant tearing tab, and a severing tape is bonded to the inner surface of the film for extending from the distal end of the tearing tab along the entire length of the film along the article wrapping direction.  The severing tape has a width lesser than the width of the tearing tab and is formed of a material  having  heat shrinkage percentage lower than that of the film.  The tearing tab  has  its  distal  end  reduced  in width  for  reducing  the allowance for heat fusion.  For reducing the allowance for heat fusion,  the distal end of the tearing tab is semi-circular in contour.  The distal end of the severing tape substantially in register with the center sealing region of the film is designed as a non-fusing region to facilitate the exfoliation of the severing tape.

IPC: H02B11/24
Filed: 1994-02-18
Abstract: The present invention provides a shutter assembly for covering an exposed electrical terminal located in a control center into which removably inserts an electrical control device connecting to the terminal. The assembly includes a shutter to cover the exposed terminal when superposed thereover. The shutter has a pivotal axis at one end, so that the opposite end of the shutter pivots away from the exposed terminal and swings clear of the control device to provide access to the terminal. The rotation of the shutter is automatically controlled to expose the terminal when the control device is inserted in the cell and reversibly pivots the shutter to cover the terminal upon removing the control device from the cell.      The present invention also provides a method of safely protecting an exposed terminal mounted in a control center. A control center is provided with a partially enclosed framework for removably inserting a control device.      Subsequently, a self-contained shutter assembly is installed for supporting a shutter in a superposed relation over the exposed terminals and for controlling the rotation of the shutter to expose the terminal when the control device is inserted in the cell and reversibly pivots the shutter to cover the terminal upon removing the control device from the yell.

Patent CA-2119211-A1 (CA)
Inventor: KRASSER FRITZ
IPC: H01H71/04
Filed: 1994-03-16
Abstract: An electrical apparatus switch (1) contains a switching rocker (3), which is mounted in an insulating housing (2), for switching on and off manually (for manual connection and disconnection). By means of an operating end (16) which enters into the housing interior (11), the switching rocker (3) moves a contact link (4) (depending on the pivoting position) between its contact closed position and contact open position. The contact link (4) is electrically connected in series with a contact spring (5) which can be released thermally and thus acts as overcurrent protection. The contact spring (5) can move between its contact position and its open position. The contact spring (5) is mechanically prestressed in the direction of its open position. In the event of an overcurrent, it is moved from its contact position into its open position by means of a thermal tripping element. It is returned from its open position into its contact position again by pivoting the switching rocker against the mechanical prestressing in the rocking direction (66) of the contact spring (5).

In this tubular furnace(1),  a coil path(3)  is divided into a plurality of zones (2a,2b,2c,2d),  at  least  one  regenerative-heating-type burner system(4)  is provided in each of the zones(2,...,2) for alternately  performing  the  supply  of  combustion  air  to burners(5,6) through regenerative beds(7,7) and the discharge of  combustion  gas  therefrom;  an  amount  of  combustion  is independently controlled in each of the zones(2a,2b,2c,2d) so that a desirable heat flux pattern can be formed such that a boundary layer temperature of the fluid to be heated in the zones(2a,2b,2c,2d) of the coil path(3) is lower than a coking temperature or lower than an allowable maximum temperature to be determined by the material for use in the heating pipe, and is set substantially the same in all of the zones.  With this arrangement,  the heat flux is increased at the  inlet zone where  the  temperature  is well below a coking temperature, while coking is prevented, a predetermined quantity of heat is provided through a smaller heat transfer area, the temperature of the tubular wall at the inlet zone is raised to avoid the corrosion at low temperature, the exhaust heat of the exhaust combustion gas is utilized to preheat the combustion air so as to achieve a heat efficiency as high as that in a furnace provided with a convection section, even without a convection section,  so that it becomes possible to render  the furnace compact in size or to increase the treating quantity.

Abstract: INTERACTIVE ADVERTISING SYSTEM FOR ON-LINE TERMINALS          ABSTRACT      There is disclosed a new system for providing advertising information into an interactive system having a plurality of remotely located terminals (12).  Each terminal (12) includes a video display unit (20), logic (19) and a video storage medium such as a hard disc (18) in addition to the normal functions of the interactive system of which an ATM is an example.  A remote centrally located commercial computer (10) capable of transmitting digitized signals representing commercial offerings and compressed digitized video signals for display on the video unit (20) communicates with each of the remotely located terminals (12).  The compressed digitized video signals are stored on the hard disc (18) of each terminal for display on the video unit (20) at times determined by the use of the terminal (12).  The user selects the services or goods offered by the terminal (12) in the conventional manner.  During the waiting time inherent in the operation of the terminal (12) a high quality video advertising message is displayed on the video unit (20) from the hard disc (18).  The message will last for less than 15 seconds and the user selected function will continue at the conclusion of the message.  The advertising message will be changed, updated and varied directly from the central computer (10).
