Abstract: Abstract of the Disclosure A novel vaccine for use in the immunotherapy of neo-plastic disease is prepared by a procedure wherein cancerous tissue is surgically removed from a patient to be treated and the tissue is disaggregated into its component cells which are then suspended in water and subjected to hydrodynamic turbulence sufficient to disrupt the cells. The "cell disruption material", possessing cancer-specific antigen, and which comprises cell surface membranes and in some cases also intracellular particles, is mixed with a source manganous ion (e.g., manganese hydrogen phosphate gel) and, optionally, a macromolecular polysaccharide carbohydrate (e.g., methyl cellulose) to produce the vaccine. It is desirable to freeze the vaccine prior to use. After thaw-ing, and subsequent inoculation into the patient, the vaccine promotes regression of the cancer through stimulation of the patient's immune response. -1-

Abstract: ABSTRACT OF THE DISCLOSURE:      An improvement of the SNAM ammonia-stripper integrated urea process is disclosed, wherein a gaseous stream obtained by decomposing hydrocarbons is fed to an adiabatic ammonia stripper placed downstram of a carbamate decomposer, the adiabatic stripper also receiving a solution of urea which is rich in ammonia coming from the carbamate decomposer.  The thus enriched stream (NH3, CO2, H2O) is processed in a CO2 -absorber (or carbamate reactor) and the process proceeds in the urea synthesis reactor. Recycling and recovery loops are provided between the several reaction and/or decomposing units.  Surprisingly enough, the stripping on NH3 and CO2 takes place adiabatically and the drop of the CO2 partial pressure in the stream fed to the carbamate reactor has no bearing on the efficiency of the carbamate conversion which, according to the current technical teachings, requires an increase of the CO2 partial pressure.

Title: Sulfided acidic multimetallic catalytic  composite and use thereof in hydrocarbon conversion
Inventor: ANTOS GEORGE J
IPC: B01J23/656
Filed: 1978-05-08
Granted: 1981-02-24
Abstract: ABSTRACT OF THE DISCLOSURE           Hydrocarbons are converted by contacting them at hydrocarbon conversion conditions with a selectively sulfided acidic multimetallic catalytic composite comprising a combination of catalytically effective amounts of a platinum group component, a sulfided rhenium component and a halogen component with a porous carrier material formed from Ziegler alumina.  The platinum group component, sulfided rhenium component and halogen component are present in the multimetallic catalytic composite in an amount, Calculated on an elemental basis, corresponding to 0.01 to 2 wt.% platinum group metal, 0.01 to 2 wt.% rhenium, 0.1 to 10 wt.% halogen and sulfur in an amount at least sufficient to provide an atomic ratio of sulfur to rhenium of at least 0.5:1.  These metallic components are moreover, relatively uniformly dispersed throughout the Ziegler aluminum carrier materail in carefully controlled oxidation state such that substantially all of the platnum group metal is present therein in the elemental metallic state and a substantial portion of the rhenium present therein is maintained in a sulfided state.  A key feature of the hydro-carbon conversion process using the subject catalyst involves the continuous maintenance of the sulfided state of the rhenium component for the duration of the hydrocarbon conversion process. A specific example of the type of hydrocarbon conversion process disclosed  herein is a process for the catalytic reforming of a low octane gasoline fraction wherein the gasoline fraction and a hydrogen stream are contacted with the instant selectively sul-fided acidic multimetallic catalyst at reforming conditions.

Abstract: ABSTRACT OF THE DISCLOSURE          A cyclicly operable machine for providing a tensioned loop of fusible thermoplastic strapping about a loosely positioned object, wherein a hoop-mounted slip-feed carrier is caused to orbit the object in one direction while one end of the strapping is held by a gripper.  In so orbiting, the carrier progressively wraps a closed loop about the object, the loop having overlapping ends which become sealed to each other by a friction-fusion operation.  Such sealing accomplished by a cooperating anvil and vibrator which move into the strap path to create the seal and away from the path to allow the sealed loop to completely seize the object, after which a cutter severs the excess strapping from the object.  A reverse orbiting of the car-rier similarly applied a successive strap loop to the object.  A strap storage and dispenser system, including a strap reel, supplies strapping to the carrier and has facilities whereby, during initial application of the loop, the relatively light tension which is applied will not unseal or dislodge the loosely positioned object and whereby, after the loop is completed, a high degree of tension becomes effective to draw the loop tight around the object immediately prior to the sealing operation.  Initial movement of the carrier in either direc-tion feeds strapping back into the storage and dispenser system during partial object wrapping, but continued motion of the carrier again withdraws such stored strapping during final wrapping.  A pinch or drag roller normally inhibits withdrawal of strapping from the reel during use of the stored strapping but releases the reel to pay out strapping when the stored strapping is exhausted.  Novel means are provided for actuating the vibrator, the anvil, the gripper and the cutter at appropriate points in the machine cycle.

Abstract: Abstract A mounting insulator for securing a pipe, conduit, or tube through a metal wall stud or other thin planar sur-face to firmly secure the pipe and reduce the noise of water hammer and dialectic interaction between the pipe and the wall stud, the device including an off-center pipe receiving passage which allows for adjustable positioning of a pipe axis relative to the stud aperture axis.       The device is comprised of a substantially annular, somewhat flexible ring having a radial slot allowing the annular body to be spread apart and an interior circular passage, the central axis of which is offset relative to the axis of the annular ring.  The circular passage includes a raised peripheral barrier and a plurality of flanges which cooperate to allow the device to be locked tightly in an aperture in a metal wall stud.  The device is mounted about a pipe by spreading the annular body at the radial slot, and then inserted in the stud aperture.  Precise alignment of the pipe through a stud aperture is achieved by rotating the de-vice which changes the position of the circular pipe receiv-ing passage around the central axis of the ring allowing for positioning adjustment of the pipe relative to the stud aper-ture. The device can be installed on a pipe already dispos-ed through the stud aperture.
