Abstract: "ACTUATION OF A GUN FIRING HEAD"                  ABSTRACT OF THE DISCLOSURE    The method and apparatus for actuating a perforating gun by pressure includes a pressure actuated gun firing head disposed on the perforating gun for detonating the shaped charges of the gun.          The gun is attached to a pipe string and located downhole adja-cent the  formation  to be  perforated.   The  pressure  actuated firing head includes a housing with a plug and piston.   The piston has a firing pin adapted for engagement with the initiator of a perforating  gun upon  reciprocation within the  housing.          Initially,  the piston is pressure balanced until the time of actuation.  The plug is responsive to fluid pressure of a prede-termined magnitude at the time of the actuation of the gun firing head.  Upon effecting pressure on the plug, the plug unbalances the piston causing the piston to reciprocate.  Upon reciprocation of the piston, the firing pin engages the initiator to detonate the  shaped charges of the perforating gun.   Pressure may be effected on the firing head through the pipe  string,  or the annulus,  or both.   The  firing head  includes  a plurality  of passageways, as well as the plug and piston, arranged in a manner whereby should leakage of well fluids into the firing head inad-vertently  occur,  the apparatus is rendered  inoperative  and therefore the firing head cannot inadvertently be fired due to the occurrence of unforeseen intervening circumstances.

Abstract: DEPARTMENT OF COMMERCE UNITED STATES PATENT OFFICE                   PUNCHING AND BINDING MACHINE            ABSTRACT OF THE DISCLOSURE         An improvement on commercial machines which bind documents using plastic strips.  The punch mechanism may be automatically actuated when the paper sheets are properly aligned on a punch platen or actuated manually at the user's discretion.  Distance of the holes from the edges of the sheets may be indexed.  The binding mechanism improvements include interchangeability of height of the pressure bar and speed of binding mechanism, depending on thickness of book to be bound or as selected by user, means for automatically starting the motor drive of the binding mechanism and pressure bar when it has been manually placed or moved onto the document to be bound, automatic lifting of the pressure bar when the binding cycle has been completed, a resistance-heated knife construction which reaches operating temperature more rapidly, controls and mini-mizes the heated knife temperature fluctuations, maintains a more uniform temperature profile of the knife, improvements in the mounting of the timing cams of the machine and improved means for securing and positioning the cooling and forming fingers in place.  In a modification, means is provided for binding a "wrap-around" cover which extends rearward of the spine of the book and then is folded forward around the binding strips for the book.         The means comprises a removable backstop for the spine edges of the sheets to be bound, a platen and roller to support the lowermost of the wrap-around covers and a rack to support the uppermost of the wrap-around covers during the binding procedure.         The knife structure is modified to avoid interference with the modified means.

Abstract: Measuring system employing a measuring method based on the triangulation principle for the non-contact measurement of a distance from the surface of a contoured object to a reference level.                         ABSTRACT       An apparatus for the rapid and accurate dimensional inspection of an object. In particular, the apparatus is adapted for the acquisition of object range data. The appa-ratus includes a source for emitting a slender beam of radiation, first beam guide means for causing the beam to impinge on a desired spot of the object under inspection, second beam guide means for causing radiation reflected from the spot of impingement to traverse a predetermined path, and a linear radiation-sensitive detector disposed in this predetermined path for receiving the reflected radiation.       The second beam guide means are adapted to image focussed spots on the detector of only those object spots which are irradiated by a predetermined sectional length portion of the emitted beam of radiation.       A preferred embodiment includes third beam guide means for causing radiation reflected from the spot of im-pingement to traverse a further predetermined path also leading to the detector.       The second and third beam guide means are structurally different from each other in such a manner that one and the same object spot irradiated by the predetermined beam portion is imaged on the detector as two separate, focussed spots spaced a fixed distance from each other. Thereby a reliable discrimination can be made between true and false reflections from the object under inspection.

Abstract: VALVE FOR HIGH PRESSURE FLUID CONTAINER                ABSTRACT OF THE DISCLOSURE        A valve having a valve housing for mounting on a high pressure fluid container. A cartridge is mounted  in  a  fluid  conduit  in  the  valve  housing leading to the fluid container.   A metallic disc is crushed by the cartridge against a valve seat in the conduit to provide a reliable lasting seal.   Opening of the valve is provided by releasing a trigger pin connected to a latch in the cartridge for removing a support from a portion of the disc permitting it to rupture under the high pressure and communicating the high pressure gas to a pressure regulator chamber in cross  configuration  with  the  valve  conduit  in  the valve housing.   A pressure regulator member in the chamber controls the size of a discharge orifice for lowering the pressure and introducing the gas into an inflatable body.   Filling of the high pressure fluid container may be done by introducing high pressure fluid into the regulator for passage into the fluid conduit of the valve with the cartridge carrying the disc spaced from the valve seat.  After the container is  filled the cartridge  including the disc support moves the disc into sealing engagement with the valve seat.

Abstract: ABSTRACT           The decoder may be used for decoding teletext signals broadcast in TV signals but may be used also for teletext-like signals, e.g. videotex  signals.          In the teletext decoder, a magazine code detector (33) detects a sought after magazine number in an error-encoded teletext signal.  A memory (64) stores all allowable magazine code numbers in error-encoded form. A keyboard (28) or remote control enters into a microprocessor (29), in encoded form, the sought after magazine number. The microprocessor (29) addresses the memory location where the corresponding error-encoded magazine number is stored to develop at the output (66) of the memory (64) those encoded bytes of data that represent the sought after magazine number.  The error-encoded encoded bytes are compared in a comparator (150) with the error-encoded bytes of incoming data in the teletext signal to determine the presence of the sought after magazine number in the teletext transmission.  Preferably a logic network (39) detects the presence of the sought after number even in the presence of a one bit error.

Abstract: TITLE            A STROKE-VECTOR CHARACTER GENERATOR     ABSTRACT OF THE DISCLOSURE          A novel stroke-vector character generator is disclosed for generating characters or the like in a raster-scan video display system.  An external data signal defines the type of character to be displayed, the character field dimensions, the character drawing point, and any character rotation or reflection.  Using that part of the data signal that defines the character type as a memory address, the character generator retrieves from memory a character micropro-gram containing a plurality of encoded binary valued stroke-drawing directives.  These directives are instructions to a decoder how to generate all of the shape dependent attributes for a series of chain related stroke-vectors that define the overall shape of the character to be displayed.  Once defined in the system, each stroke-vector is scaled so that the character cell size matches the character field dimensions defined by the external data signal.  Lastly a logical pel may be generated and added to the individual stroke-vectors before the connected stroke-vectors are projected onto the display screen at the character drawing point.
