Abstract: INVENTOR:   CARLOS ROS NAVARRO          INVENTION:  METHOD OF, AND APPARATUS FOR, CONTINUOUSLY             CASTING A CURVED STRAND USING A CURVED RIGID DUMMY BAR              ABSTRACT OF THE DISCLOSURE            In a curved or arc-type continuous casting installation provided with a curved or arc-type rigid dummy bar the curved dummy bar is separated from the cast strand at the region of the straightener by means of a movable roller. To improve the economy and to increase the decoupling reliabi-lity the dummy bar head is provided with a permanent coup-ling member which is disengageable from the cast strand by performing a pivoting movement. Furthermore, the dummy bar head is pivotably connected or linked to the dummy bar so as to be pivotable about an axis extending transversely with respect to the strand moving direction. For disenga-gement of the dummy bar head from the cast strand the mo-vable roller presses upon the pivotable dummy bar head so that the same, during the casting operation, is pivo-ted outwardly out of its axial position away from the curved longitudinal axis of the curved dummy bar.

Abstract: Abstract A method and Means of Making an Explosive in the Form of an Emulsion.    A method for producing an emulsion explosive composition is disclosed.  In the method, the discontinuous phase comprising an aqueous solution of an oxidizing salt is jetted through a plurality of fine jets into the fuel/ emulsifier continuous phase.  The mixture is, then, passed through at least one mixer to achieve final, fine emulsification.  The method provides a convenient means of controlling droplet size and, hence, the properties of the explosive product.

Abstract: Printing Machine Abstract A printing machine for applying marks at specified locations on a moving web.  The machine has specific utility in check or document signing applications where a number of forms are successively signed by a signature stamp.  In accordance with a preferred embodiment of the invention the machine has one motor for driving a web of paper to a print station and a second motor for activating a stamp by rotating the stamp into contact with the web.  The motors are individually energizable under control of a programmable controller.  By co-ordinating the times and duration of motor energization the spacing between successive marks can be varied over a wide range of values.  The flexibility in print spac-ing allows the printing machine to be used in conjunc-tion with the processing stations such as word proces-sing and the like.

Gravitational opening of the pocket is further enabled by virtue of the transverse upper edge of the pocket panel being disposed at a higher elevation than the top ends of the side seams of the pocket when viewed with the bib in its use orientation and/or by securing together face-to-face areas of the pocket panel and the apron panel which are disposed adjacent their coextensive upper edges. Preferably such areas which are secured in face-to-face relation are centrally disposed with respect to the width of the bib. Also, preferably, the bib is a unitary structure comprising a sheet of a crease sustaining laminated material having an absorbent front lamina, and wherein the panels are demarked from each other by transverse fold lines which have been creased. Additionally, the bib may further comprise: a duplex refastenable tape fastener; a line-of-weakening to enable detaching all or part of the apron panel for use as a post-use wipe; and a detachable neck-opening portion.

Abstract: ABSTRACT OF THE DISCLOSURE        A supply of steam is fed to a drying cylinder (10) from a steam line (20) through a steam pressure control valve (22).  Condensate and steam are removed from the drying cylin-der to a separator (32).  The pressure of the removed steam is controlled by a steam pressure control valve (36) and the rate of condensate removal is monitored by a condensate removal mon-itor (48).  A computer controller (16) adjusts the steam feed and removal pressure control valves to maintain the smallest differential pressure therebetween which will maintain the con-densate removal rate substantially constant.  The computer con-troller sets an initial pressure differential during an ini-tializing step (50).  In a first pressure differential adjust-ment step (52), the computer decreases the pressured differen-tial in first increments until the condensate removal rate be-gins to decrease.  In response to the decrease, the first pres-sure differential adjusting step increases the pressure differ-ential by the first increment.  A second pressure differential adjusting step (54) functions like the first pressure differen-tial adjusting step but uses a smaller increment.  A checking step (56) periodically increases the pressure differential by the second increment and returns the program to the second pressure differential adjusting step to reestablish an optimal pressure differential.

Abstract: Abstract Porous Metal Structures Made by Thermal Spraying Fugitive Material and Metal Porous metal deposits especially useful in gas turbine engines as compressor seals are made by thermal spraying a metal powder and a meltable polymer powder mixture, wherein the spraying process and a subsequent polymer removal process are chosen to produce less than 30 weight percent oxide. Oxide contents of 4-25% are typical.  When 86 weight percent nichrome is sprayed wth 14 weight percent polymethylmethacrylate the polymer is removed by heating in air to about 315°C.

Abstract: ABSTRACT OF THE DISCLOSURE A swiching power source circuit intermittently switches a primary winding current of a transformer according to a repeatedly switching bipolar transistor,rectifying and smoothing an output voltage induced at a secondary transformer winding. A capacitor is charged by a voltage induced by a feedback winding of the transformer. The base-emitter path of the bipolar transistor is reverse biased by the capacitor voltage to perform high-speed switching, so that a compact transformer and capacitor can be used, and the switching power source circuit becomes low in cost. The application of the reverse bias voltage is performed by a transistor which is turned on when an emitter grounded through a resistor) voltage of the bipolar transistor is increased to a predetermined level (threshold). A switching period of the bipolar transistor is determined by an R-C period determining circuit. The capacitor of this circuit is charged to reverse bias the bipolar transistor when the bipolar transistor is turned on, and is discharged when the bipolar transistor is turned off. An auxiliary winding is arranged in the transformer to detect flyback energy, and the ON and OFF times of the bipolar transistor are controlled to stabilize the output voltage even in an overload.
