Abstract: ABSTRACT OF THE DISCLOSURE            In a heating and mixing apparatus having an elongated cavity and a plurality of heating tubes extending along the length of the cavity, the improvement comprises at least one supporting member for the tubes and lying across the cavity along a plane approximately normal to the axis of the tubes and having a plurality of orifices through which the tubes extend.  The support member has at least one opening therein to allow composition to pass therethrough, and preferably a plurality of the supports are spaced along the drum and disposed so that the openings of adjacent supports are not aligned with one another, thereby acting as temporary barriers for the composition as it is drawn gravitationally from one end of the apparatus to the other during heating and mixing process.  In another embodiment, a portion of the support extends exteriorly of the drum and is exposed whereby the exposed portion may be agitated and which agitation is translated through the support to the tubes which causes vibration for assist in removing composition coated on the tubes.

Abstract: ABSTRACT          Apparatus for optically reading a record of disc form on which video information is contained in parallel tracks. Said apparatus includes a tracking sys-tem for ensuring that the scanning spot follows a desired track. In order to enable said scanning spot to jump from any given track to an adjacent track, a switching device is provided which is adapted to supply a suitable control signal to the tracking system. Said control signal is automatically adjusted to variations in track spacing and the like, so that correct track-jumping displacements of the scanning spot are ensured.

Abstract: ABSTRACT OF THE DISCLOSURE    An internal combustion piston engine has a prechamber or auxiliary chamber associated with each main combustion chamber and connected thereto by a plurality of torch openings.  Ignition of a relatively rich mixture in the auxiliary chamber causes flames to be projected through the torch openings to ignite the relatively lean mixture in the main combustion chamber.  At least three torch openings are provided in the bottom wall of the auxiliary chamber; one is directed toward the main intake valve in the main combustion chamber, another is directed toward the exhaust valve in the main combustion chamber, and a third directs a flame toward a region of the main combustion chamber remote from both valves.  Additional torch openings are employed for larger engines.  The relative positions of the torch openings are defined as well as their total cross sectional area compared to the volume of the auxiliary combustion chamber.

Abstract: CHANNEL SELECTING APPARATUS              ABSTRACT OF THE DISCLOSURE           In a channel selecting apparatus for a television receiver having an electronic tuning tuner for changing the receiving frequency in accordance with an analog control signal applied thereto; a memory is provided with a plurality of addresses at which respective digital codes each intended to identify a respective broadcast channel are selectively stored or written in a programming mode of the apparatus, and, in a channel selecting mode of the apparatus, a selected channel identifying digital code is read out of the memory to a digital-to analog converter which converts the same into a respective analog control signal for tuning the tuner to a receiving frequency.  Any deviation of the receiving frequency, as established in response to the analog control signal, from the transmitting frequency for the channel identified by the digital code then being read out of the memory is detected, and in response thereto the digital code being applied to the digital-to-analog converter is modified or changed in the sense for removing the deviation and thereby effecting a fine tuning operation.  When, in the channel selecting mode, the detected deviation of the established receiving frequency from the transmitting frequency exceeds a predetermined amount, the resulting modified digital code may be automatically stored or rewritten in the memory in place of the read out digital code resulting in such deviation.  The writing of digital codes in the memory in the programming mode and the rewriting of modified digital codes in the memory in the channel selecting mode are permitted only if, at the time of such writing or rewriting, there is being received a broadcast signal with a transmitted frequency corresponding to the receiving frequency established by the digital code to be written or rewritten in the memory.

Abstract: ABSTRACT OF THE DISCLOSURE         A method of selective plugging of undesirable high permea-bility streaks and channels in oil-bearing reservoirs during high tem-perature (250°F or higher) injection recovery processes such as steam-flooding, underground combustion, flooding of a naturally occurring high-temperature reservoir or the like.  Improved sweep efficiency can be effected by injecting a gel-forming solution consisting essentially of sodium lignosulfonate and water or brine in the absence of other gelation promoters and then allowing the high temperatures of the under-ground formation to promote gelation.  Optionally, a precooling water injection step can be used prior to placement of the gel-forming solu-tion.  This system has the advantage of gel times which are sufficiently long at temperatures in excess of 250°F to permit placement of large volumes characteristic of commercial use.  This method is particularly useful in selectively forming firm, strong gels in thief zones for steamflooding recovery operations.

Abstract: CAPSULE MANUFACTURE                    Abstract of the Disclosure A process is disclosed for performing encapsulation, en masse, by an in situ polymerization reaction to yield capsule wall material.  The polymerization includes a reaction between urea and formaldehyde or polycondensation of monomeric or low molecular weight polymers of dimethylol urea or methylated dimethylol urea in an aqueous vehicle and the reaction is conducted in the presence of negatively-charged, carboxyl-substituted, linear aliphatic hydro-carbon polyelectrolyte material dissolved in the vehicle.  Liquid-liquid phase separation is accomplished and maintained by increase in the molecular weight of the resulting condensation polymer with-out further dilution of the manufacturing vehicle.  The negatively-charged polyelectrolyte material is required and has an apparent effect of controlling or modifying the polymerization reaction. The disclosed encapsulation process permits manufacture of micro-capsules in concentrations of capsule to capsule manufacturing vehicle higher than previously possible.
