Abstract: Abstract A mixing device for dispensing a mixture of moulding sand and a resin binder system onto a mold forming pattern is disclosed.  The mixing chamber has an inlet for receiving sand adjacent an upper level and a dis-charge outlet for the mixture adjacent a lower end.  A rotor mounted in the chamber includes an upstanding rotating shaft extending between the inlet and the outlet and a plurality of radially extending mixing elements carried for rotation with the shaft.  There are means for injecting binder into the cham-ber between the inlet and outlet for intimate mixing with the sand moved around the shaft by the mixing elements.  The injecting means includes a first conduit for injecting a first component of a resin binding system adjacent a first portion of the chamber and a second conduit for injecting a second com-ponent of a resin binder system into a second portion of the chamber inter-mediate the level of the first injecting conduit and the outlet of the chamber. Plates with orifices between said first and second conduits divide said chamber into first and second sections for controlling the flow of intermixed sand and the first component therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE             A method of making a cap and a cap made thereby.          A plurality of panels each having  an upwardly extending tapered portion are  assembled into a cap with hems along the tapered edges of each panel sewn to the hems of adjacent panels to form the crown of the cap.  The tapered portions of the panels are surface ornamented prior to assembly with a decoration having directionally oriented portions which cross the seam of the cap at a crossing angle other than perpendicular to the seams.  The directionally oriented portions are extended across the hems to the tapered edges of said panel at an angle perpendicular to the tapered edges.  When the panels are assembled into the crown of the cap, the extended directionally oriented portions on the hem of one panel are placed against corresponding extended directionally oriented portions on the hem of the adjacent panel before sewing the hems to each other, so that the directionally oriented portions on the panel one one side of a seam will be in exact register with the directionally oriented portions on the panel on the other side of the seam.  The directionally oriented portions of the surface ornamentation can be extended along the top surface of the visor of the cap.

Abstract: BASE FOR TELEPHONE SET, FOR ALTERNATIVE DESK AND WALL MOUNTING            Abstract of the Disclosure An adaptable telephone baseplate can be used for either wall mounting or desk or table top mounting.  The baseplate has an enclosed recess at an intermediate position and a modular jack position at what would be the top edge when wall mounted.  A slot connects the jack position and enclosed recess.  When wall mounted a short cord can be inserted in the slot with a plug at one end being inserted in the jack at the jack position and a plug at the other end being in the recess for insertion into a wall jack.  When desk mounted a normal line cord enters through a groove into the jack position for insertion of a plug into a jack. Alternatively a line cord can enter through the groove, extend along the slot and then pass up through the slot for hard wiring of the conductors to a circuitboard.  Snap-in mountings are provided for the jack, a circuit board, ringer and possibly other items.  For some telephones a battery housing can be provided while in others the battery housing can be omitted, by the alternative use of two inserts in the mold for the baseplate.                         - i -

Abstract: Abstract A locking gas cap adapted for universal use with both larger-diameter and smaller-diameter filler necks includes a central cylindrical closure member extending downwardly from the cap shell and having a diameter just slightly smaller than the smaller-diameter filler necks to guide the closure telescopically into the end of the smaller-diameter filler neck, and a pair of opposed, perimetrally extending indentations formed in the circumference of the closure member for cooperating with perimetrally extending protrusions formed in a cylindrical outer sleeve member to lock the sleeve member onto the closure member.  The sleeve member has an outside diameter slightly smaller than the larger-diameter filler necks to guide the closure telescopically onto the larger-diameter filler necks when the sleeve is in place, to adapt the gas cap to the larger-diameter filler necks.  An annular gasket is mounted onto the closure member and includes a sleeve section which grips the closure member, an annular outer section for engaging the upper lip portions of the filler necks of both larger- and smaller-diameter filler necks and an axially inwardly opening central annular recess portion for receiving the sleeve member so that the sleeve member extends substantially to the axially outer end of the closure member.

Abstract: Abstract of the Disclosure A real-time monitor which displays analog represent-ations of digital seismic data having been recorded on magnetic tape such that adjacent seismic traces are partially overlapped, whereby the appearance of an error is enhanced and is disclosed.          The monitor display is controlled by a computer which may be of a type similar to computers used in the seismic data storage system for other purposes so that it may serve as a back-up computer.          This system is implemented by incorporating into magnetic tape data storage drives read-after-write circuitry so that the data put on the tape can be read off the tape immediately thereafter and used to control the monitor means.  In this way, the monitor is in fact operating in real-time and operates on precisely that data which is on the tape; thus any errors displayed on the real-time monitor include any errors made in the actual recordation of the data onto magnetic tape.

Abstract: ISLAND REFRIGERATED DISPLAY CASE           WITH AIR DEFROST               ABSTRACT OF THE DISCLOSURE     An island refrigerated display case can be construct-ed so as to in effect constitute to back-to-back display cases that can be arranged as a separate aisle within a supermarket.          Such an island refrigerated display case has two interior display spaces separated by a partition wall with each display space having its own access opening so as to enable refrigerated products to be removed from that portion of the case.  Encircling each of the interior display spaces is an associated refrigeration air conduit.  Each of the refrigeration air conduits has an inlet and outlet opening positioned so as to direct air across the corresponding access opening for the interior display space.          Thus during the refrigeration cycle of operation, a refrigerated air curtain is formed between the corresponding outer wall and the center partition wall so as to extend across the associated access opening.  The portions of the refrigeration air conduits that extend through the partition wall can be joined so as to form a single chamber.  In this manner, the evaporator coils can be located either along each of the refrigeration air conduits or in the central chamber within the partition wall.  The island display cases are defrosted by an ambient air defrost system in which ambient air is drawn into and circulated through the refrigeration air conduits for defrosting any frost buildup within such conduits.

Abstract: ABSTRACT         A pipe coupling for application to plain end pipe and pipe pile by a driving force.  It provides much greater tensile strength than the double sleeve type of pipe coupling disclosed and claimed in my U. S. Patent No. 4,053,247 in that it provides a greater strength under tension.  In one embodiment, a pair of tapered wedge rings are disposed in spaced coaxial relation within an outer cylindrical sleeve having corres-ponding tapered inner surfaces to provide tapered annular sockets into which pipe sections may be forced or driven to expand the diameter of the pipe.  An annular shoulder on the sleeve forms the bottom of the annular sockets.  Under tension, the tapered rings wedge the pipe against the outer sleeve to resist axial removal of the pipe from the coupling socket.  In another embodiment, the tapered wedge rings are disposed in coaxial relation outside the cylindrical sleeve to form annular tapered sockets which serve to reduce the diameter of the pipe as it is driven into the socket.  Various other modifications, utilizing a similar wedge-ring principle, serve to couple pipe sections of different diameters respectively. Another embodi-ment of coupling employs the wedge-ring principle to couple two sections of reinforced pre-cast concrete pipe pile.  Another embodiment provides an end fitting for reinforcing the end of a pipe pile and employs the wedge-ring principle to resist removal of the end fitting.
