Abstract: COMPOSITE BREECH PLUG FOR BLACK POWDER GUNS                   Abstract of the Disclosure A breech plug for sealing the breech end of black powder guns is constructed of two pieces.  The first piece is an inner plug which threadedly engages internal threads at the breech end of the barrel and creates a bore seal.  The second piece is an outer housing adapted to mate with the inner plug and to effect alignment with the barrel flat sides and barrel breech end.  An assembly technique utilizing this composite breech plug greatly simplifies the machining pro-cedures and reduces the cost normally associated with producing high quality black powder guns with a full hook breech plug.

Abstract: ABSTRACT OF THE DISCLOSURE           The present invention provides a lintel for supporting arches over doors, windows and like openings in a wall.  The lintel is made of relatively thin sheet metal and has at least one load-carrying shank so that the lintel in spite of its thin construction can carry great loads during the walling of the arch.  Each shank is provided with a longitudinally extending material weakening e.g. a series of slots, perforations, or at least one groove.  The material weakening forms a fracture indication along which the shank can be folded or broken off, when the mortar has set and the brickwork has become self-supporting.

Abstract: LOW PROFILE MINING MACHINE            Abstract of the Disclosure -To maintain the lowest possible machine profile be-tween the bottoms of the crawler treads and the top of the turret, the boom of the machine and boom lifting cylinders are cantilevered forwardly of the turret and depressed to lie as closely as possible to the underlying gathering head of the machine without clogging the throat of the machine and/or inter-fering with the operation of the gathering arms.  The boom pivot and boom lift cylinders are disposed ahead of the crawler treads and the connections of the boom lift cylinders with the turret are forwardly of the highest part of the gathering head.  This geometry renders it possible to significantly lower the eleva-tion of the machine turret on which the boom is mounted for sluing or swinging movement and thus minimize the total height or profile of the mining machine.

Abstract: ABSTRACT       A card reader having  a  limited  capacity  for  use  with digitally  encoded  cards  is  used  in  conjunction with a system requiring a greater amount of information than  is  encoded  on a single  card.    A  multiple stage buffer storage memory is placed between the card reader and the utilization system.    The  memory has  specific memory locations corresponding to locator data which is uniquely encoded on each of the different cards  of  a  set  of cards   employed  to  supply  the  necessary  information  to  the utilization system.  A data locator is connected between the  card reader  and  the buffer storage means and is responsive to locator data r ad from the cards by the reader to direct  the  information data  on  the  cards to the proper location in the buffer storage memory.  The cards may be inserted  into the reader in any  order; and  when  all  of the areas of the buffet storage memory have the necessary data encoded in them,  the  information  is transferred from the buffer storage memory to the utilization system.
