Abstract: ABSTRACT OF THE DISCLOSURE A shear pin assembly suitable for use in a rocket retention and release system is provided.  Each shear pin has a head and a shank with a passageway extending axially along the length of the shear pin.  In the rocket release system, the shear pin connects a shear pin ring to the rear end of the rocket.  A hole to receive the shear pin is provided in both the shear pin ring and the rear end of the rocket.  The hole in the ring extends completely therethrough and has a diameter less than the diameter of the hole in the rocket.  The passageway in the pin has parallel sides in long-itudinal cross-section at the head end of the pin and sides which taper in-wardly towards the shank end of the p m at the shank end.  When the pin-is inserted into the holes to connect the ring and rear end of the rocket to-gether, the pin is expanded by a mandrel so that a shank end portion of the pin in the hole of the rocket fills the cross-section of the hole.  Prefer-ably a solid plug is then inserted in the passageway of the pin by means of a punch.  When inserted in the pin, the plug is located entirely in the shank end portion of the pin located in the hole in the rear end of the rocket. Preferably the outer end of the inserted plug is located just below the shear plane formed between the ring and the rocket.

Abstract: ALTITUDE COMPENSATION IN CARBURETOR             CHOKE SYSTEMS                    ABSTRACT OF THE DISCLOSURE          In a carburetor having a choke mechanism including a thermostatically responsive bimetallic coiled spring that exerts an increasing closing force on the choke valve as the temperature decreases below the normal engine operating level, an intermittently operable heater device is provided adjacent the bimetallic spring to reduce the spring closing force on the choke valve when operable.  The heater device is rendered operable by an engine vacuum responsive switch to compensate for increases in altitude which would tend to decrease manifold vacuum.  The heater device is also and alternatively rendered operable by a temperature sensitive switch to achieve more rapid choke valve opening once a predetermined temperature level has been achieved.

Abstract: ABSTRACT OF DISCLOSURE A spark ignition reciprocatory internal combustion engine with dual induction system and with EGR system is provided in which under engine operating conditions when only a primary throttle valve opens, a fluid charge from a primary induction system will swirl around the cylinder axis, while, under engine operating condition when both the primary and secondary throttle valves open, a fluid charge from a secondary induction system will impede and reduce swirling motion of fluid charge from the primary induction system.   With the EGR system, the recirculation of exhaust gas is effected through the primary induction system under the engine operating condition with low and intermediate loads.  At high loads, the recirculation of exhaust gas is effected not only through the primary induction system but also through the secondary induction system.  For this end the EGR system includes a load responsive valve which will permit admission of exhaust gas into the secondary induction system at a position downstream of the second-ary throttle valve in response to loads of the engine.

The signal S is preferably a signal representing the ratio of the demodulated constituents.  Any abnormal behavior of at least one Or a plurality of continuous casting factors, particularly those related to the covering, material on the liquid metal, is detected by comparing the signal S with an analog-type reference signal considered as ideal for satisfactory casting. The abnormal behaviour is corrected by modifying the factor concerned so that the signal S comes as close as possible to the reference signal.

Abstract: SHALE STABILIZING DRILLING FLUID   ABSTRACT OF THE DISCLOSURE         A  process and composition are described for use in drilling shale and especially in drilling the troublesome types of shale which heretofore have been impossible to drill effectively.  The aqueous drilling fluid of this invention so effectively stabilizes the shale that additions to maintain the special drilling fluid can be discon-tinued or drastically reduced, once the shale formation has been pene-trated and drilling below the shale could even be done with conventional drilling fluids.         The drilling fluid contains between about 0.2 to 1.5 pounds per barrel of flaxseed gum together with potassium and/or ammonium salts.  The potassium and/or ammonium salts are used in quantities to provide a concentration of the cation of the salt of at least 10,000 ppm. As the drilling fluid is a non-clay type, a non-clay viscosifier is used.  Preferably, the cation concentration is tailored to drilling fluid salinity such that the cation concentration in parts per million is approximately equal to at least 10,000x(1+0.025x the sodium chloride salinity in percent saturation).

Abstract: ABSTRACT OF THE DISCLOSURE          In a television reproduction system in which recorded video for one field, either odd or even, is repeatedly scanned, such as for still or slow motion reproduction, and is displayed with a locally generated synchronizing signal which produces interlaced scanning having both odd and even fields on a television screen, video from adjacent lines is averaged when the recorded field being scanned is an odd or even field and the field defined by the synchronizing signal is the opposite type.  When the recorded video is a color video signal, the luminance and chrominance components of the video signal are separately averaged, the chrominance component is inverted in dependence on the relationship between the phase of the color subcarrier of the recorded line being reproduced and the phase of the color subcarrier of the locally generated synchronizing signal.

Abstract: ABSTRACT OF THE DISCLOSURE      An improved method for manufacturing a heat transfer assembly particularly useful as a component of a radiator used to remove heat from the coolant of an internal combustion engine.  The heat transfer assembly includes a plurality of louvered fin strips having fold edges that are in heat transfer contact, through solder joints, with flat-sided tubes designed to carry the fluid to be cooled by a flow of air contacting both the exterior surfaces of the tubes and the fin strip surfaces.  The improved method involves the application of beads of solder to the fold edges of the fin strips, rather than to the tubes as in the prior art, before assembly of the fin strips and the tubes.  The improved method reduces the amount of solder required and thereby reduces manufacturing cost.
