Abstract: MAGNETIC DISK-JACKET ASSEMBLY                ABSTRACT OF THE DISCLOSURE A disk-jacket assembly including a flexible disk rotatably disposed in a square jacket having radially extending registering slots in its two thicknesses for receiving a pair of opposite transducers or alternately a single transducer in one slot and a pressure member in the other slot.  Panels of porous low friction dusting fabric are disposed between the faces of the disk and the opposite inner faces of the jacket.  The dusting fabric has slots coincident with the slots in the jacket, and the dusting fabric slots are wider than the jacket slots particularly for spacing the disk entry side edges of the jacket slots from the adjacent edges of the fabric to substantially prevent loose fibers on the fabric extending into the jacket slots.

Abstract: (5205) IMPROVED PREPARATION OF VANADIUM PHOSPHORUS CATALYSTS                              ABSTRACT The present invention provides a method for the preparation of oxidation catalysts containing mixed oxides of vanadium and phosphorus, which catalysts are particularly effective in the oxidation of n-butane, n-butenes, 1,3-butadiene or a mixture thereof with molecular oxygen or an oxygen-containing gas in the vapor phase to produce improved yields of maleic anhydride with good selectivity. A vanadium compound is at least partially solubilized in an organic liquid medium capable of reducing at least a portion of the vanadium to a +4 valence state, and unsolubilized vanadium having a particle size larger than about 0.1 mm diameter is removed from the medium before addition of a phosphorus-containing compound.

Abstract: HOLD CIRCUIT FOR TELEPHONE SYSTEM            ABSTRACT OF THE DISCLOSURE          A single master unit hold cirucit which can be utilized for a single or a group of telephone instruments connected to a common telephone line.  A single latching circuit is coupled to the telephone line.  The establishment of the hold condition may be affected in the off-hook state of the telephone instrument.  Each of the telephones of the group has associated signaling capability. Each telephone can generate an actuating signal directly onto the telephone line, which is then detected by the latching circuit, and in response thereto a hold condition is placed on the telephone line.  The hold condition is effected via the telephone line, by a momentary actuation of a control circuit common to the hold circuit and the control circuit; the control circuit being a part of the telephone instrument call-out circuit network.  The signal-ing can be accomplished by the rotary dial on a dial phone instru-ment or by the push button pad on an instrument sold under the trademark Touch-tone, or by means of other types of frequency generating devices.  The hold condition is initiated and estab-lished while the phone instrument is in its off-hook state. Moreover, the active telephone instrument continues to remain in its voice communication state, the hold condition having been established, notwithstanding, as long as the telephone receiver is not placed on-hook.  A key feature of the invention is that the off-hook state and/or voice transmission state of the tele-phone instrument constitutes the decisive conduit or channel by which the control means can activate the hold circuit.  The hold circuit cannot readily become activiated when the telephone receiver (handset) is in the on-hook state.

Abstract: RCA 73,776 Abstract of the Disclosure A flat panel display device includes a baseplate assembly which can be readily fabricated using mass production techniques.  An insulative modulator support member is affixed to the baseplate in a location accurately defined with respect to location notches in the baseplate. A distal mesh support is accurately located and maintained with respect to the location notches in a transverse direction and is loosely held in a longitudinal direction. The modulator support member and the distal mesh support contain slots which loosely receive vanes while holding the vanes perpendicular to the baseplate.  The vanes thus form channels which extend longitudinally along the baseplate and perpendicular to the modulator support.  The modulator support contains a recess extending transversely across the baseplate and a plurality of longitudinally extending recesses positioned in the proximity of the center of the channels.  Tabs on beam guide assemblies engage the recesses to maintain precise spacing between the beam guide assemblies and modulator support.  Tabs on the distal ends of the beam guide assemblies engage recesses in the distal mesh support.  Grooves in the vanes receive beads which couple the meshes forming the beam guide assemblies.  Upon evacuation of the envelope formed by mating the baseplate assembly with a front wall and side walls atmospheric pressure retains the assembly in the desired orientation and the vanes support the baseplate and front wall against collapse.

Abstract: TITLE: VALVE FOR SUBTERRANEAN WELLS                       ABSTRACT OF THE INVENTION    The invention relates to an improved subterranean well safety valve wherein an annular actuator is moved downwardly by applied fluid pressure to effect the opening movement of a valve head of a valve relative to an annular valve seat.  The initial downward movement of the actuator effects the displacement of a valve stem which extends through a restricted aperture in the valve head, moving a ball valve segment on the valve stem from a seat in the aperture, thus permitting the bleeding of any fluid pressure differential existing on the lower side of the valve head relative to the upper side and reducing the amount of force required to move the valve to its open position.  Additionally, in one embodiment, a locking sleeve is slidably mounted within the shiftable annular actuator and such sleeve is operable by an auxiliary tool to effect the radial shifting of locking elements carried by the actuator into locking engagement with the valve housing to achieve a temporary locking of the valve in an open position.  The travel of the locking sleeve relative to the valve housing in a reverse direction is limited by a shearable pin so that reverse forcible movement of the locking sleeve will shear the pin and effect a permanent locking of the radially expansible locking segments carried by the actuating sleeve to the valve housing, thus permanently locking the valve in an open position.

Abstract: ABSTRACT     Risk of fracture of an optical fibre in an overhead stranded electric conductor having an optical fibre loosely housed in an elongate compartment extending throughout the length of the conductor when the conductor is subjected to a tensile load greater than that which the optical fibre is designed to withstand is substantially reduced by supporting the stranded conductor from each of two opposite sides of a tower by suspension means incorporating a weak link designed to fracture at a tensile load less than that which the optical fibre can withstand before fracturing.  An excess length of the stranded conductor extends between fittings at which the suspension means are secured to the conductor, is arranged sinuously down one side face of the tower and, where the stranded conductor is an earth conductor, is detachably secured to the tower at spaced positions along its length by releasable clips.  When the tensile load on the stranded conductor increases to a value greater than that which the weak links can withstand, a weak link will fracture and the excess length of stranded conductor will be detached from the tower to reduce the load on the stranded conductor and thereby reduce risk of optical fibre fracture.

Abstract: ABSTRACT OF THE DISCLOSURE A method is disclosed for applying thermal and/or chemical treatment to a dispersible fluid phase, such as in particular a liquid, semi-liquid or powder, by means of a dispersing gas phase, characterized in that the following steps take place successively and without discontinuity, by the action of the gas phase:  (a)  the dispersible phase is converted to a dispersion of component volumes, such as fine solid or liquid particles, which are substantially evenly distributed within said gas phase so as to give a systematically homogeneous mixture of the two phases, namely the dispersible and dispersing phases; (b) the dispersion undergoes flash treatment in a zone with plug type flow; (c)  the dispersion emanating from zone of step (b) undergoes treatment which is both substantially isothermal and chemically homogeneous, in a zone with a flow which is homogeneous in the sense of the distribution of dwell times.  The method of the invention overcomes some tricky problems which have plagued prior efforts in this field.  The products of the method of the invention are useful in the food and detergent manufacturing industries.
