Abstract: ABSTRACT OF THE DISCLOSURE         A casting mould block for the semi-continuous or continuous casting of large profile metal blocks has a casting mould stool containing water chambers and moulds.  The water chambers have outlets in the form of gaps.  Blocking tongues extend into the gaps and can be tilted from a pos-ition along one side of the gap to a position extending across it, so as to adjust the degree of opening of the gaps.  The tongues are resiliently biased to their "open" positions and may be formed as parts of the springs that provide the bias.  Set screws are used to adjust the positions of the tongues.  The individual tongues can be adjusted independently to provide for independent control of the water flow from each slot.

Abstract: ABSTRACT         A  remotely  controlled  verification   lockout   of   the verification  memory  used  in  conjunction  with fuel dispensing systems,  service  dispensing  systems  (such  as  automatic  bank tellers),  and  the  like  is  provided.  At each user location, a verification memory is provided in which a single binary data  bit is  stored  at each different verification address location.  Each document  or  credit  card  used  with  the  system   has   unique identifying  information  encoded  on it for addressing a specific location in the memory which corresponds to the verification check for  that  credit  card.    Provision  is  made  for automatically initializing the status of all of the information stored in all of the  verification memories in the system by the transmission of an initializing signal to those memories from a central processor  by way  of suitable communications lines.  In addition, on a periodic basis or at irregular intervals a change  in  the  status  of  any address location in the verification memory may be effected by the central  processor  transmitting  a  control  character  which  is decoded  by  logic  at  the  fuel  dispensing station to place the verification memory in  its  "write"  mode  of  operation.    This character  then is followed by the addresses of the various memory locations which are to be changed or updated, and those  addresses are  changed  accordingly.    Thus,  each  of the different memory locations which are to be changed are  individually  addressed  to establish  the  "valid"  or "non-valid" binary data bit storage at the location corresponding to the different credit cards for which the verification memory status is being changed.

Abstract: ABSTRACT      In an optical alignment and exposure machine, particularly suited for aligning semiconductive wafers with and exposing them to microelectronic circuit patterns, two stages of mechanical prealignment of the wafers are performed.  In the first stage of mechanical prealignment a wafer is received at a prealign-ment station where the periphery of the wafer engages at least one of three belt-driven rollers in such a manner as to turn the wafer so as to align a flat side edge or alignment flat of the wafer with two of the three rollers.  A transfer arm picks up the first-stage prealigned wafer and transfers it to a rotatable alignment and exposure chuck carried by an X-Y addressable work stage.  In the second stage of mechanical prealignment two alignment members coupled to the rotatable chuck for rotation therewith index with the alignment flat of the wafer, and additional alignment members also coupled to the rotatable chuck for rotation therewith index either the center of the wafer or a rounded side edge of the wafer to a predetermined position.  An optical alignment system permits rotation of the chuck to more precisely align images of align-ment marks on the wafer with alignment marks on the mask.  Follow-ing such precision alignment of the first wafer, the second stage of mechanical prealignment of each succeeding wafer is performed at the final angular position of the chuck during the preceding precision alignment performed with the optical alignment system. Apparatus is coupled to the chuck for selectively moving a wafer supported on the chuck into engagement with a stop to accurately position the plane of an emulsion on the wafer with respect to a focal plane of the optical alignment system.

Abstract: A floating dock ABSTRACT          In order to make possible a "self-docking" of a floating dock, the same is divided into a middle pon-toon      and two end pontoons         .  These are in-terconnectable in alternative positions in the vertical direction, one normal operating position, and two "self-docking" positions  The middle portion      is designed to lift both end portions            , and the latter are designed together to lift the middle pontoon.           The pontoons are held together by bolts      , which are accessible from cofferdam-like spaces       , formed when two pontoons are fitted together, and which may be maintained watertight. Male and female coupling members      are furthermore provided to secure the pon-toons in their two operative positions.           During a disconnecting and connecting opera-tion the pontoons are guided by means, which may include rigid link arms     , or chains      or the like. The ballast arrangements within the end pontoons will have to be designed so they, in the first mentioned case will permit a trimming transversely, and in the latter case permit a trimming longitudinally as well as transversely.
