Abstract: ABSTRACT     A punched card reader for use in systems such as bulk fuel terminal dispensing  systems,  automated  unattended  bank  teller machines  and  the  like  includes  security provisions to prevent operation of such systems by counterfeit cards. Specifically,  the system  operates  with a punched card made of laminated plastic or the like having a rectangular  plate  made  of  magnetic  material sandwiched  between  the  card layers. This plate is located in an area of the card adjacent the portion encoded  with  the  variable data  uniquely  identifying the card and controlling its function, etc.  The card entry throat of the tape reader is modified to have a pair of spaced-apart, magnetically actuated reed switches on one side of the card entry slot. On the  opposite  side  of the  cord entry  slot a pair of corresponding permanent magnets are located.          The magnets have  a  field  strength  sufficient  to  operate  the magnetic  reed switches; so that when no card is inserted into the reader, or when a card not having the magnetic  shield  in  it  is inserted  into  the reader, the reader cannot operate. When a card having the magnetic shield  in  it  is  inserted  fully  into  the reading  position  of  the  reader, the magnetic shield breaks the magnetic field used to actuate the reed switches, and they  change operating  state.  This  state  of  operation is used in a control circuit, along with  the  conventional  card  sensing  switch,  to enable the reader for operation.

Abstract: ABSTRACT OF THE DISCLOSURE         This control device for electric motor reducer intended for driving rolling shutters, roller-blinds or the like, and permitting an accidental overstepping of the electri-cal stop point without causing any damage in, or putting out of order, the control device, comprises a cam having a notch formed in its contour, adapted to be engaged by a follower portion of a lever so as to open a switch controlling the supply of drive current to the motor reducer.  The notch has a rear portion inclined laterally and rearwardly which opens into an extension of the cam contour which is level with the bottom of the notch, or located at a lower level than this bottom.  When the cam rotating in a given direction oversteps the normal electrical stop point the inclined portion moves the follower laterally and the lever is moved laterally along     , its pivot axis against the force of spring means, but held at the same level.

Abstract: ABSTRACT OF THE INVENTION A wood-burning heating apparatus, used as a parlor stove, and providing a significant heat output is disclosed.  The stove has primary and secondary combustion chambers and a baffling arrangement for directing flue gases along a circuitous path to the exit aperture whereby a significant proportion of the heat of said gases is given up to the apparatus.  A vertically oriented downwardly directed baffle separates the combustion chambers.  Primary and secondary air paths supply air to the primary and secondary combustion chambers respectively.  Each of the supply conduits is pre-heated and the secondary air supply provides oxygen substantially evenly around an opening at a bottom portion of the baffle to increase the efficiency of secondary combustion.  The apparatus is further provided with a self-clearing top smoke chamber having a pivotable top cover.  A rotatable flue collar is provided for either a horizontal or a vertical connection to the exit flue.

Abstract: ABSTRACT        A dispenser for wound rolls of flexible sheet material, such as, paper towels, toilet tissue or the like has inwardly facing tracks on the opposite inner side walls of the dispenser housing to receive therein outwardly projecting spindles carried by wound rolls to be dispensed for the rolls to move in succession downwardly relative to the tracks with a section of the lower end of each track slanting away from a feed roller mounted adjacent the lower end of the dispenser housing and each track having at such lower end section a pivotally mounted roll rotation driving guide biased toward the track center to form the lower side of each track section slanting away from the feed roller. A pressure roller is biased into rotating engagement with the feed roller for flexible sheet material to drivingly pass therebetween with the pressure roller having at least one resiliently deformable segment that is eccentric to the pressure roller axis to pick up the leading free end of sheet material on a full roll and lead it into the nip between the feed roller and pressure roller, this pressure roller also has axially spaced conical resilient portions along the length thereof with the conical portions facing from the opposite ends of the pressure roll inwardly toward the mid-point of the pressure roll to promote spreading out the sheet material passing between the feed roller and the pressure roller. A serrated cutting knife is pivotally mounted within the feed roller to sever the sheet material, the serrations on the knife being spaced to accommodate therebetween the deformable eccentric segment and the conical portions on the pressure roller during initial projection of the knife from within the feed roller in severing the sheet material. The cutting knife swings about an axis laterally displaced from the plane of a radially outward portion of the knife and cam followers are carried by the ends of the knife extending beyond the ends of the feed roller with the followers displaced from the pivot mounting axis of the knife. Stationary cams are mounted adjacent the ends of the feed roller with which the cam followers on the knife edge engage to positively project the knife cutting edge beyond the feed roller periphery and retract the cutting edge upon rotation of the feed roller.

Abstract: Abstract The  invention  relates  to batch  feeders  for  furnaces. Heratofore batch feeders have been complex,  expensive to construct, use  and  maintain  and  have  not  ensured  a  uniform  deposition of particulate batch material onto the batch cover in the furnace.  The present  invention provides  a method and apparatus  for obtaining a uniform layer of batch material by moving a particulate-containing trough 62 over a desired area.  Disposed within the trough 62 is a vibrating  agitator  80  comprising  a pivotable  perforated  discharge chamber  94  which  is  caused  to  pivot back and forth through the particulate material in the trough 62.   The particulate material is forced through the perforations 87 in the agitator 80 and falls, under the influence of gravity,  towards the desired area.   The size and distribution of the perforations 87, the selection of the open area and depth of the perforations 87 along with the vibration amplitude and frequency of the agitator 80,  control the through put of batch material onto the melt area so that when the agitator 80 is motionless, no particulate is deposited within the desired area but when the agitator is actuated an even distribution is effectuated.

Abstract: ABSTRACT OF THE DISCLOSURE A reclining article of furniture for sitting, especially an office chair, with the article including a seat portion and a back portion articulated thereto.  The seat portion and back portion are respectively connected to an underframe.  The seat portion is supported in a forward zone and the back portion is supported by a supporting lever articulated to the underframe and articulated to the back portion at the hip level of a user, to obtain a support which is also effective in the zone of the lumbodorsal vertebrae and to provide a close contact of the supporting surfaces with the user's body.  The contact is uniform in the rest position approximately from the back of the knees up to the shoulder blades.  The seat and back merge through an arcute intermediate section which is flexible so that the arc can become wider.  A connecting line extending between two points of articulation of the supporting lever in a basic position of the chair is inclined at an angle of between 0° and 25° and, preferrably, between 15° and 25°, with respect to the vertical.  By virtue of these features, the seat surface is initially lengthened toward the rear before a stronger rearward inclination of the back occurs when the seat is moved from an upright sitting attitude to a reclined attitude.
