Abstract: Abstract An    improved    process    for    economically converting  carbo-metallic oils  to  lighter  products.          Enhanced catalyst activity is enjoyed through use of a select process to vaporize and atomize the high boiling portion   of   a   carbo-metallic   oil    feed.     The carbo-metallic  oil  feed  is  dispersed  into  droplets having a diameter of at least smaller than 350 microns and  preferably  100  microns  or  less.   These  small droplets  ensure  more  even  coverage  of  the  catalyst surface  and  decrease  diffusion  problems.   The  water utilized for dispersion of the carbo-metallic oil feed is present as a homogenized mixture in fine oil droplets with an average diameter below 1,000 microns.  The water is dispersed in the carbo-metallic oil feed through use of  a  select mixing apparatus and can be dispersed as finer droplet  sizes  through use  of an emulsifying or dispersing agent.  The ratio of water to carbo-metallic oil  feed ranges  from about 0.04 to 0.25 by weight and the concentration of emulsifying agent ranges from 0.01 to 10 wt% based on the weight of water.

Abstract: Abstract of the Disclosure A device for adjusting the angular position of a movable support has two frames which are pivotally connected to each other along a pivot axis and are capable of being moved apart by the action of pretensioned torsion spring rods provided near the pivot axis so that the two frames assume variable angular positions with respect to each other.        The movable support frame in its upwardly directed angular position may serve as a supporting surface for a mattress at the head end of a bed frame.  To effect angular adjustment, two steel cables fastened to one frame are trained over pulleys disposed on the other frame and are guided to a pivot lever pivotably attached to the other frame and are actuated by an electric motor.  As the motor is operative, the steel cables cause the frames to be pulled in one direction toward each other against the action of the torsion spring rods and the pneumatic springs.          Reversing the direction of the motor will cause the frames to move away from each other due to the action of the torsion spring rods and pneumatic springs.

Abstract: ABSTRACT OF THE DISCLOSURE           The underwater operating unit shown in Fig. 1 comprises a hollow body which is specially reinforced, against bending moments and compressive forces acting upon it, by means of flow-ducts (for drive-elements) passing longitudinally therethrough and by permanently incorporated, multi-purpose pressure chambers.  Unit is held by, and supplied through, a holding- and supply-cable.  A main grab, adjustable to widely varying gripping diameters and located at front-end, is adapted to cling to pipes, wrecks, and the like so firmly that the unit itself, and the booms extend-ing therefrom (tool-arm, auxiliary grab, platform), may be subjected to heavy loading as a fixed work-base both for hand-tools operated by divers and for entirely remote-controlled, un-manned manipulators, in spite of the small dimensions.   Control-elements and drive-elements allow unit to be used both as a vehicle, as a mobile unit, as a hoist, as a machine tool, and as a power-base for auxiliary equip-ment used in underwater operations, also in confined pipe-structures and cavities, in a particularly efficient and safe manner, and to be rapidly and reliably adapted to vary-ing operation conditions by the use of replaceable, modular pieces of auxiliary equipment etc.

Abstract: ABSTRACT     The present invention provides a novel method of packing a plurality of articles such as cans and bottles in trays and a novel machine adapted thereto.  According to the method there is provided in a hopper station a stack of pre-cut paperboard blanks each having crease lines defining a bottom panel, front and rear walls with flaps and a pair of end walls. One of the tray blanks is pulled from the bottom of the stack, and creased along the front wall crease lines.  The front wall is cammed into a square position with the bottom panel, and the rear wall is creased.  The blank so partially formed is pushed from the hopper station to a packing station, while the front wall is held in a square position with the bottom panel. The front wall of the tray is guided into a desired position within the packing station with the bottom panel, the rear wall and the end walls under a dead plate.  A load of cans or the like is delivered over the dead plate and contacts the front wall of the tray, drawing the tray blank out from under the dead plate and pushing the loaded partially formed tray away from the packing station.  The tray front wall flaps are folded into square position with the front wall.  The loaded partially formed tray is conveyed to tray erecting and sealing means where the rear wall flaps are kicked into square position with the rear walls and the rear wall is erected into square position with the bottom panel, and for erecting.  The end walls are erected into square position with the bottom panel and into adhesive contact with the front and rear flaps.  The novel machine comprises a hopper station, a packing station, a glue station, and tray erecting and sealing means.  The hopper station includes means for holding the stack of pre-cut paper-board blanks, means for pulling one of the tray blanks from the bottom of the stack, and forming therefrom a partially formed blank, and means for holding the front wall of the blank in a square position with the bottom panel during the transfer from the hopper station to the packing station.  The packing station includes means for holding the tray front wall flaps into square position with the front wall, and for maintaining the front wall in that position, a dead plate, gate means for guiding the front wall of the tray into a desired position, means for delivering a load of cans or the like over the dead plate, a downstream dead plate, means for rotating the gate away from the front wall  and means for conveying the loaded partially formed tray to said glue station.  The glue station includes means for applying glue to the opposite ends of the end walls of the tray.  The tray erecting and sealing means includes means for kicking the rear wall flaps into square position with the rear walls, means for erecting the rear wall into square position with the bottom panel, and means for erecting the end walls into square position with the bottom panel and into adhesive contact with the front and rear flaps.

Abstract: ABSTRACT         This invention relates to a filter for x-ray examining devices.          An x-ray examining apparatus comprises a source of an ionizing and penetrative radiation (e.g. an x-ray tube), an object plane wherein the patient is positioned, and an image plane on the opposite side of the object plane relative to the radiation source.  The image recording medium is disposed in the image plane.          When exposing chest x-rays, if the source of radiation is kept at a level that will provide a proper viewing density to the lungs, the level of radiation will not be sufficient to provide acceptable exposure of parts of the body that are composed of dense tissue, e.g., the spine and the heart.          The filter of this invention comprises a sheet of radiation absorbing material having an opening therein, said opening corresponding to the spine and central portion of the heart.  Accordingly the upper portion of the filter exhibits a relatively narrow opening which becomes gradually wider toward the lower portion of the filter. This filter will permit an acceptable density level of x-ray exposure for the lungs while allowing a higher level of x-ray exposure for the mediastinum areas of the body.

Abstract: ABSTRACT                  REMOVING PHOSPHORUS FROM IRON    To remove phosphorus from iron to a desired level, a charge of the iron is melted in a vessel followed by either (1) supplying gas such as 40% CO2 + 9% CO + 51% H2 to the charge before melting is complete, or (ii) adding, to the charge, iron which is partly or wholly oxidised equivalent to adding iron ore of up to 8% of the charge weight, or a combination of (i) and (ii), such as would at 1600°C supply an oxygen partial pressure of at least 10-10 atmospheres.  Then, when the surface of the charge is substan-tially molten but before the surface of the charge reaches 1550°C., either (a) slag is removed from the surface of the charge or (b) a refractory oxide compatible with the vessel lining is added suffi-cient to form a viscous slag or (c) (permissible only with a basic vessel lining) basic oxide(s) and optionally a flux are added to form a fluid slag.
