Abstract: Abstract of Disclosure An electric low-voltage current-limiting fuse completely or substantially complying with the Underwriters Laboratories Inc. Standard Class R fuses. The current carrying part of the fuse comprises a fusible element having serially arranged perforations. This part may be of silver or of copper. The current carrying part Of the fuses further comprises tabs of copper bent over the rims of the  casing and conductively interconnecting the ends of the fusible element with the terminal caps of the fuse. The fusible element is provided with an M-effect metal to limit the tempera-ture rise of the fusible element and of the casing. The tabs are considerably thicker than the fusible element. If the fusible ele-ment is of silver the thickness of the tabs of copper is larger than the thickness required to fully compensate for their higher resistivity. The ratio of the thickness of a pair of tabs of copper to the thickness of a fusible element of silver depends upon the geometrical configuration of the latter and is in the range of 2:1 to somewhat less than 5:1. Since the tabs are thicker than the fusible element both cannot be joined by conventional rolling operations. Each of the pair of tabs is formed by a part separate from the fusible element. These tabs are affixed by electroconductive bonds such as, e.g.spot-welds, to the fusible element.    The application shows in detail fuses having fusible elements of silver and tabs of copper. With the rising price of silver it may be necessary to substitute for the fusible elements of silver fusible elements of copper. At the present time silver is, however, the preferred metal for the fusible element proper.    In this application silver and copper have been designated by the generic term current-limiting metals. Virtually all current-limiting fuses manufactured at this time have fusible elements of either copper, or silver. The reason for this fact is that silver and copper have close pre-arcing I2-t values, that of silver being 8.00 x 108 ohm/cm, and that of copper 11.72 x 108 ohm/cm.

Abstract: ABSTRACT OF THE DISCLOSURE    An open mouth power tong is described having a novel arrangement for preventing relative rotation between the tong cage plates and rotary gear in situations where the pipe is not gripped at the completion of the camming action and in situa-tions where the tong parts must be aligned for placing the tong on a pipe or removing it from a pipe.  The assembly includes a pair of arcuate grooves formed in the upper surface of the rotary gear--one for use in make up operations and the other for use in break out operations.  A rigid pin member is provided for extending through one of a pair of apertures formed in the upper cage plate.  When the camming action is complete, i.e., when the cam followers have reached the extremities of the cam surfaces, the rigid pin member engages the remote boundary of the respective arcuate groove so as to join the cage plates and rotary gear and cause them to rotate together.  When it is desired to align the tong parts for pipe access, the pin engages the near boundary of the groove.

Abstract: ACOUSTIC HOOD WITH GLARE SHIELD                 Abstract of the Invention The device disclosed is a combination sound hood and glare suppressing visor for use on office machines such as typewriters, where it is necessary to contain machine operating noise and suppress acoustic sound levels while at the same time retaining visibility of the document being printed.    The device is capable of movement away from the paper opening of the typewriter or office machine to allow access to the printing zone or printing region of the typewriter and, upon the removal of the device from the region of the printing zone, the glare shield is lowered or collapsed controllably to remove obstructions to operator access of the printing zone.  As the sound hood is replaced over the paper aperture of the typewriter or printer, the glare shield is again erected to its preset position to suppress glare from overhead and back lighting illumination.  The visor may be adjusted and preset by the operator to present substantially a line or edge view thereof, thereby minimizing the distraction to the operator. The sound hood may be pivotally raised to a vertical or past vertical position to give access to the printing element or the typing zone.  As the hood itself is raised, the angle between the hood and the visor is reduced until it becomes substantially zero, at which point the visor is raised along with the hood and positioned out of the way leaning backward away from the operator.  As the hood is repositioned over the opening of the top of the typewriter to contain the acoustic vibrations, the visor is again positioned in its preset position.

Abstract: A B S T R A C T         In the generation of hydrogen fluoride gas for the product of AlF3 by the reaction of fluorspar with concentrated sulphuric acid a small amount of aluminium sulphate is introduced into the reactive mix to assist in the retention of phosphorous compounds in the solid residues of the reaction and thus reduce the phosphorous content of the gaseous HF. Aluminium sulphate may be added as alum or may be generated in situ in the sulphuric acid by addition of an alumina hydrate, preferably before the acid is brought into contact with fluorspar.  The addition of a small amount of calcium carbonate to the fluorspar also improves retention of phosphorous compounds in the solid residues in some instances.

Abstract: Abstract of the Disclosure A method of producing surface height patterned materials by application of streams of pressurized, heated fluid into surface areas of a relatively moving material having thermally modifiable surface components.  The heated fluid streams are selectively activated and deactivated in accordance with pattern information to strike selected sur-face areas of the material to thermally shrink and compact the surface areas by a desired amount.  Heated fluid stream flow is controlled by use of cooler pressurized fluid which is selectively directed into the heated fluid stream flow to block the same from striking the surface of the moving material.  The temperature of selected of the heated fluid streams striking the material is controllably varied by rapidly introducing small amounts of cooler fluid which blend into the heated streams to correspondingly vary the height reduction of the surface of the material.       The method is particularly suited for production of patterned pile fabrics containing thermoplastic pile yarn components, whereby the height of the pile yarns in the areas contacted by the streams may be reduced by vary-ing amounts, depending upon the pattern-controlled intro-duction of cooler fluid into the heated fluid streams.       Multiple height, surface-patterned products pro-duced by the aforementioned method are also disclosed.
