Title: Automated shaping of cellular packing cores to fit delicate goods - by filling an inverted thermo:formed sheet with foam distributed to suit scanned cavity profile
IPC: B29C51/10
Filed: 1986-06-18
Abstract: Automatic prepn. of shaped cellular linings for packaging involves thermoforming a sheet of thermoplastic material to the appropriate surface profile to fit/support/cover the item to be filled with a foam-forming material. Foam injection is effected by equipment with a scanning device to determine the shape and depth profiles of the recess in the inverted sheet and to use these signals to control the position of and delivery by a mobile foam mix injection nozzle.

Title: Plane bottomed converter - uses horizontal oxygen jet at acute angle to diameter
IPC: C21C5/34
Filed: 1971-11-04
Abstract: Method of refining cast iron in which a blast of oxygen is blown into the melt from a jet surrounded by a protective curtain of an indothermically dissociating fluid using at least and pref. one only one tuyere of two concentric ducts arranged at the lower part of the lateral wall of the converter. The longitudinal axis of the tuyere makes an acute angle (is approx. 10 degrees) with the diameter of the converter to improve the wettin of scrap metal, and is directed horizontally. Apparatus permits the use of a plane bottomed furnace rather than one with a number of holes in the refractory which is thus mechanically stronger in service.

Abstract: ABSTRACT     An improved process has been developed for preparing chloromethyl methyl ether containing very low concentrations of bis(chloromethyl)ether.  Methylal is saturated with hydrogen chloride under essentially anhydrous conditions to form an equilibrium mixture of chloromethyl methyl ether, methylal, hydrogen chloride and methanol containing less than 5 ppm bis(chloro-methyl)ether.  Then the chloromethyl methyl ether is recovered by selective solvent extraction, preferably with a liquid aliphatic hydrocarbon.  Chloromethyl methyl ether thus prepared is used as an intermediate for pre-paring aromatic chloromethylated compounds.

Abstract: ABSTRACT OF THE DISCLOSURE           The detection of immunologically reactive biological particles such as viruses, bacteria and other cells is obtained by detection of the occurrence of an immunological reaction on a substrate between the particle to be detected and its radioactive-tagged antibody.  A first immunologically reactive biological particle is absorbed onto the surface of the substrate in a particular monomolecular layer pattern, and the substrate is then exposed to a solution suspected of containing the particles to be detected which are specific to the first particle.  Finally, the substrate is exposed to the radioactive-tagged antibody to the particle to be detected, and the pattern substrate surface is monitored for radio-activity by searching for the particular pattern which emits a high radiation level, if it exists.

Abstract: PHF. 75-616.     ABSTRACT:     Phase discriminator in a receiver of a system for data transmission by means of phase modulation of a carrier.  The phase discriminator comprises a calculating unit arranged for receiving digital signals, whose associated signal samples occur at a rate equal to the data modulation rate, the digital signals being represen-tative of the in-phase and quadrature components of the received passband signals at each sampling instant and of the in-phase and quadrature components of a reference carrier at a preceding sampling instant.  This calculating unit calculates the signal samples of digitsl signals which are representative of the in-phase and quadrature compo-nents of a signal which is derived from the received pass-band signal by a phase shift over an angle which is equal and opposite to the phase of the reference carrier at the preceding sampling instant.  The digital signals supplied by the calculating unit are applied to a decision circuit which at each sampling instant determines the phase varia-tion of the transmitted carrier during one sampling period and reproduces the corresponding phase jump.  In case the reference carrier is locally generated, the decision circuit also supplies an error signal for locking the phase of the local reference carrier on the received carrier.

The tubular conductor includes a flattened terminal plate at a first end projecting outwardly of the heating element and at the second opposite end includes a compression sleeve portion extending axially therefrom and projecting inwardly of the heating element.   An end of the resistance wire of the heating coil is inserted into the central bore of the inwardly pro-jecting compression sleeve portion which is crimped to secure the end of the resistance wire to the second end of the terminal.          The flattened plate formed at the first end of the terminal is drawn into abutment against the two-piece clamp member, and the second opposite end is similarly flattened at the point immediately adjacent the opposite side of the clamp member.   The terminal is thus secured to the insulated two-piece clamp member to prevent substantial axial movement relative thereto, and to hold the two-pieces of the member together with the frame of the heating element securely clamped therebetween.   The outwardly extending terminal plate is provided with an aperture to receive a screw or other fastening means for connection to a conductor leading to an electri-cal source.
