Abstract: ABSTRACT OF THE DISCLOSURE        A pull tab pivotally connected to a slider body is formed integral with a locking pawl which projects into the guide channel in the slider body through an aperture formed in its top wing.  When the pull tab is turned to a recumbent position on the slider body, the locking pawl presses the fastener elements in the guide channel against the bottom wing of the slider body thereby locking the slider against movement.  The point of contact of the locking pawl with the fastener element is located forward-ly of the axis of the pivotal motion of the pull tab when the latter is in the recumbent position.  Further, when the pull tab is in the recumbent position, the tip of the locking pawl rests against an abutment on the inside sur-face of the top wing of the slider body.

Abstract: ABSTRACT OF THE DISCLOSURE           Circuitry for automatically and dynamically reconfig-uring the channel or port configuration of a modem handling a plurality of ports.  A standard signal such as DTR (data terminal ready) is used to provide a code to a master modem indicating the particular port configuration requested by cooperating apparatus.         The requested configuration code is continuously compared to a code stored by a shift register controlling the actual modem port configuration.  When the requested code changes, an indication of the code change is transmitted to a communicating slave modem and a control signal is sent, after a suitable delay, to the shift register to conform its contents to the newly requested configura-tion code.  During the delay, the slave modem switches to the newly requested configuration.  The circuitry follows a defined sequence of configuration switching, dropping channels successively and adding channels by passing through the state where all channels are active.  In an alternative system operation, each of two communicating modems may be synchronized by the cooperating appara-tus such that a configuration charge need not be communicated across the transmission line.

Abstract: Abstract of the Disclosure Dispensing apparatus has a body defining therein a tubular chamber with an outer wall of generally circular cross-section.  A generally coaxial discharge orifice at an end of this chamber is closed by a first valve that includes a member of generally circular cross-section.  That member also forms an inner chamber wall and defines with the outer chamber wall an annular discharge passage that is convergent towards the discharge orifice. An annular outlet is in one of the chamber walls and first passage means is arranged to supply liquid to be dispensed to the annular outlet for discharge into the discharge passage.  Second passage means is provided for directing gas under pressure into the chamber for flow through the discharge passage, past the annular outlet and out the orifice.  A second valve in the body seals the second passage from the chamber, and operator means is provided for operating the first and second valves concurrently to open the discharge orifice and to allow gas under pressure to flow through the annular outlet through the discharge orifice and form a spray of generally conical pattern.

Abstract: ABSTRACT A method and apparatus is disclosed for examining a plane through a body by detecting the absorption of X- or gamma ray beams directed tangent to concentric rings defined in the body plane as the beams are rotated three hundred sixty degrees around the outside of the body.  Signals proportional to the detected beams are used to generate signals proportional to absorption or transmission coefficients of defined concentric ring elements.  These coefficients are useful in describing the interior of the body at the plane under examination.

Abstract: ABSTRACT OF THE DISCLOSURE         The removal of color bodies from an olefinic or saturated endo-endo hexacyclic homodimer of norbornadiene or mixtures thereof is accomplished by the use of a serpentine clay. Also acid bentonite clay or a montmorillonite clay can be used to remove the color bodies from the saturated dimer.          The saturated dimer has a high density and a high heat of combustion making it useful as a missile fuel.  Removal of the color bodies avoids possible catalyst poisoning in the hydro-genation of the olefinic to the saturated dimer.  Also removal of the color bodies from the saturated dimer eliminates the possible problem of a material precipitating out on engine turbine blades and causing maintenance or operational problems.

Title: Method and apparatus for producing  moulded-chocolate articles

IPC: B29C45/37
Filed: 1980-04-09
Granted: 1982-08-03
Abstract: ABSTRACT A method and an apparatus for producing articles made of moulded chocolate, employ an injection tool and a multipartite hollow mould enclosed on all sides except for the injection opening.  Before the mould is closed, a retaining and transporting element is placed therein, this element being adapted to fit the lower mould in the areas where it comes into contact with the chocolate compound.  Liquid chocolate is then injected through an injection nozzle at a high pressure into the cavity thus formed.  The mould is cooled during and after the injection operation.  Thereafter, the mould is opened and the retaining and transporting element, with the moulded-chocolate article adhering thereto, is removed and passed on for final cooling.  As compared with known methods, the invention substantially accelerates the production method, since cooling the mould produces a considerable reduction in the overall cooling time.  In addition to this, the number of relatively expensive moulds required  is reduced, since each mould may be opened shortly after the injection operation, the moulded article may be removed by means of the retaining and transporting element, and the mould is then ready for the next injection operation.

Abstract: HUMANE BLEEDER ARROW     Inventors:  Robert J. Repinski and Enoch B. Pratt ABSTRACT OF THE DISCLOSURE        A humane hunting arrow which is particularly designed to most effectively obtain the utmost bleed-out possible for a given hit in the shortest period of time.  The shaft of the arrow is hollow and is designed to facilitate passage of blood therethrough.  Further, the shaft may be provided, either on its inside or outside surfaces, with one or a plurality of weakened areas in the form of grooves, scratches, scored or marked lines, or the like, for facilitating shearing of the arrow shaft thereat after the hit has been registered.  Clean breakage of the arrow shaft at the point adjacent the animal's flesh facilitates bleed-out,  The broadhead arrow tip includes means for creating a reservoir near the open front end of the arrow shaft for further facilitating and expediting the passage of blood therethrough.  The means for attaching the broadhead to the shaft allows the complete inside diameter of the arrow shaft to be free of obstructions to further facilitate bleed-out, The attachment means further provides a tension means which allows the pointed broadhead to easily enter the hide and to slide off bone and hard cartilage beneath the hide to enable the broadhead to penetrate the flesh of the animal deep enough to even further facilitate bleed-out.
