Abstract: APPARATUS FOR ISOLATING THE VOICE FREQUENCY PATH          FROM THE FLOATING BATTERY FEED DURING SIGNALLING by CONSTANTINE VICTOR SKIDANENKO and GREGOR DONALD McGIBBON                    ABSTRACT OF THE DISCLOSURE    In a floating battery feed circuit, the voice frequency is normally connected on the subscriber loop side of the blocking capaci-tor which is used to prevent the DC loop current from flowing in the winding of the associated voice frequency transformer.  This capacitor adversely offsets the dial pulse signals.  An optical isolator is re-sponsive to the answer control signal from a dial pulse originating (DPO) channel unit and provides a control signal to a switching cir-cult, which connects the voice frequency circuit to the loop during answer periods and disconnects the voice frequency circuit from the loop during dial pulse signaling.

Abstract: ABSTRACT:            An optically readable storage disc comprises a transparent substrate 1 in which a recording layer 2 is deposited which can be modified locally by means of a radiation beam, the recording layer is covered by a cover disc 3 which is secured to the substrate in a gas-tight manner at some distance from the part of the recording layer which is intended for recording, so that a sealed space 4 is enclosed between the substrate 1 and the cover disc 3. The cover disc 3 will be deformed to the greatest extent under the influence of differences between the gas pressure in the sealed space 4 and the barometric pressure because its resistance to deformation is made substantially smaller than that of the substrate so that deformation of the substrate 1 is substantially precluded.

Abstract: RETARDING SETTING OF CRUTCHER SLURRY FOR     MANUFACTURING BASE BEADS FOR DETERGENT COMPOSITIONS            ABSTRACT OF THE DISCLOSURE: A process is described for retarding or preventing the setting of a miscible and pumpable crutcher slurry intended to be spray dried to base beads for subsequent conver-sion to a built synthetic organic nonionic detergent composi-tion.  The slurry, which contains described proportions or water softening zeolite, water soluble salt(s), including sodium bicarbonate and sodium carbonate, and a swelling bentonite, sometimes sets up in the crutcher in which it is being prepared.  Often such solidification is spontaneous after the bentonite has been added to the crutcher, and sometimes occurs only minutes after such addition.  When 0.5 to 5% of magnesium sulfate is incorporated in the crutcher mix such undesirable setting of the mix is delayed or prevented entirely, and crutching times of at least one hour (and sometimes appreciably longer) are attained, after which the crutcher slurry is still miscible, and is pumpable to a spray drying tower.  In addition to sodium bicarbonate and sodium carbonate the crutcher mixes may also contain sodium sesquicarbonate (sometimes at least partially in replacement of the bicarbonate and carbonate), sodium sulfate and small amounts of sodium silicate, with the proportion of sodium silicate being no more than 2% of the crutcher mix, and desirably being nil.  No citric acid or citrate is required to help maintain the fluidity of the crutcher slurry and citric materials are omitted from the crutcher mixes.         The invention also relates to the crutcher slurries made, a process for making spray dried beads from the described crutcher slurries, base beads made from the slurries by such spray drying process, and built synthetic organic nonionic detergent compositions made from such base beads by absorption therein of suitable nonionic detergent.           This invention relates to a process for retarding or preventing the setting of a miscible and pumpable crutcher slurry which is suitable for spray drying to base beads that are useful for the manufacture of detergent compositions.          More particularly, the invention relates to retarding or preventing the setting of such slurries which include relative-ly high proportions of normally solid materials and relatively little water, and in which the bentonite is present together with zeolite and a water soluble sodium salt of a certain type.         In the preparation of detergent compositions of the built synthetic organic nonionic detergent type it is

Abstract: Abstract of the Disclosure A subterranean viscous oil bearing formation is progressively produced in a preselected direction by a combination of steps conducted in sets of wells spaced from each other in the preselected direction.  A first set of wells is used to both apply electrical heat to the for-mation and inject brine, preferably at low rates.   Then electrical heating and brine injection are applied to a second set of wells spaced in the preselected direction from the first set of wells.  Electrical heating in the first of wells is ceased and hot aqueous fluid injection is commenced.  These steps are moved in sequence to coact with each other and traverse and produce the formation thereby providing a more energy efficient process.  Varia-tions cover electrically stimulated huff and puff backflowing or producing steps to control wellbore resistance and distri-bute the heat uniformly in the proper direction.  A pressure maintenance fluid may also be injected in the depleted part of the formation.
