Abstract: METHOD AND APPARATUS USING FLEXIBLE HOSE IN LOGGING HIGHLY DEVIATED OR VERY HOT EARTH BOREHOLES     Abstract of the Disclosure.  After drilling an earth borehole, the drill pipe and drill bit are removed from the bore-hole and the drill pipe is reinserted into the borehole.  A flexible hose such as a fire  hose, and having a retro-nozzle at its lower end, is then pumped down through the interior of the drill pipe and a portion of the hose is pumped out through the end of the drill pipe for a desired distance.  A well logging instrument is pumped through the flexible hose which extends down past the bottom of the drill pipe and well logging operations are performed through the flexible hose.  In very hot wells, the drilling mud or other circulating fluid can continue to be pumped through the flexible hose to provide cooling of the well logging instrument.

Abstract: ABSTRACT OF THE DISCLOSURE     A gate valve structure for use in mains carrying fluids, the gate valve structure being provided with an improved valve seat arrangement.  The gate valve includes a casing having an unobstructed through-bore and a substantially rectangular shape or elongated chamber communicating with the through-bore in which a gate or disc member reciprocates between closed and opened positions of the valve.  The valve casing is provided with a valve seat surrounding one of the ports in the casing defined at the inter-section of the through-bore by the elongated chamber, the valve seat lying generally in a plane which converges at an acute angle to a plane normal to the axis of the through-bore and the seat has an upper planar portion facing the other of the ports except at the bottom portion where it merges smoothly into and forms a portion of the unobstructed through-bore.  The gate member is provided with a resilient seal member for seating on the valve seat, the seal member having a configuration to conform to the seat so that the seal member is not damaged during opening or closing of the valve by edges in the interior of the valve resulting from the machining  of the valve seat.  Further, because of the irregular shape of the resilient seal member, means are provided so that the seal member may be properly oriented onto the gate member during assembly and the gate member is provided with ears which cooperate with guideways in the valve casing in such a manner as to minimize rock of the gate member during opening and closing of the valve regardless of the direction of flow of fluid through the valve and, thus, eliminating problems resulting in damaging of the resilient seal member from the wedging action in closing.

Abstract: ABSTRACT OF THE DISCLOSURE          A hair dryer, the temperature of the air stream from which is automatically controlled by the temperature of the hair being dried, is provided.  The dryer includes a primary air inlet, a fan for blowing inlet air out of the dryer, and a heater by which the blown air is heated before it is directed against a user's hair.  The dryer also includes a feedback air duct and a thermistor positioned in the duct to sense the temperature of the air being reflected off the user's hair as it is dried.  In accordance with the temperature of the reflected air, the thermistor changes resistance, which change is sensed by an integrated circuit zero crossing switch that electronically signals a thyristor causing the thyristor either to switch off or proportionally reduce the power to the heater, and therefore the amount of heat energy input in the blown air.  Consequently, the temperature of the air being blown against the user's hair is continuously monitored as the hair dries to avoid the hair and scalp from becoming overheated.

Abstract: ABSTRACT NEW TETRAPEPTIDES AND METHODS There are disclosed new biologically active polypeptides containing the following polypeptide seg-ment:          -ALA-LYS-SER-GLN-.          Biological activity is generally retained upon substi-tution of a natural or non-natural amino acid residue for either or both of L-alanyl in the first position and L-seryl in the third position.    These polypeptides have the capability of in-ducing the differentiation of T-lymphocytes as measured by the acquisition of the thymic differentiation antigen Th-1, as well as B-lymphocytes as measured by the acquisi-tion of the differentiation antigen Bu-1.  The polypeptides are thus useful in thymic function and immunity areas such as in treatment for congenital absence of thymus.  Also provided are substituted polypeptides, methods of manu-facture of the polypeptides, therapeutic compositions, and methods for use of the polypeptides.

Abstract: ABSTRACT OF THE DISCLOSURE          A fuel injection system for an internal combus-tion engine for injecting fuel the internal combustion engine having a plurality of cylinder by means of a single fuel injector.  Problem to be solved reside in that fuel injected in synchronism with respective suction strokes of the plural cylinder through the single fuel injector can not distributed uniformly to the individual cylinders over a whole operating range of the engine due to lag in transportation of the injected fuel to the cylinders and delay in operation of an electromagnetic valve of the fuel injector.  For a four-cylinder engine in which the suction stroke is repeated in the order of a first, a third, a fourth and a second cylinders, the single fuel injector (202) responds to a control signal from a control system (500) thereby to initiate a single-shot injection upon the suction strokes of the first and the fourth cylinders.  The fuel injection initiating timing as well as the injecting duration are arithmetically determined by CPU (502) and ROM (504) of the control system (500) on the basis of the signals representative of operating conditions of the engine available from a hot-wire sensor (116), a crank angle detector (314), a temperature sensor (316), an O2-sensor (406) and supplied to the single fuel injector (202).  The first and fourth cylinders to which the fuel is to be injected are changed over to the second and the third cylinders by CPU (502) in response to the signal output from the O2-sensor (406).

Abstract: ABSTRACT OF THE DISCLOSURE           A liquid, particularly but not exclusively a liquid of human origin such as blood serum or urine, is immunoassayed for antibodies, antigens or antibody: antigen complexes, using as a reagent in the analysis an active fraction from mouse ascitic fluid.  This active fraction is a euglobulin and has the ability, like human C1q, to combine with antibody:antigen complexes but not with free antibody or antigen.  Unlike human C1q, however, it remains active at high pH's and its activity is not destroyed by 0.1M putrescine or 0.1M hydrazine, so analyses on human body fluids can be carried out at high pH's or in the presence of putrescine and hydrazine, without interference from endogenous human C1q.  The active fraction is a very broadly applicable reagent in immunoassays and particularly useful in techniques involving agglutination of latex particles.

Abstract: "LOG SPLITTER"          ABSTRACT OF THE DISCLOSURE         An electrically driven log splitter comprises a frame with a double wedge assembly on one end and a ram carriage slidable along the frame towards and away from the wedge assembly so that a log on the frame will be engaged against the wedge assembly and be split thereby when the ram carriage engages the other end of the log.  An electric motor drives an endless chain at a constant speed with the chain extending around sprockets mounted on the frame and being driven by the electric motor through reduction components.          The ram carriage mounts a pair of sprockets with the chain passing over one sprocket and under the other.  This permits the carriage to be moved manually along the frame with the chain idling over these two sprockets,  A log is mounted on the frame against the wedge assembly and the carriage is mov-ed manually along the frame to engage the rear end of the log with the chain idling around the two sprockets within the carriage.  An operating handle with a pin extending there-from is pivotally mounted on the carriage and is moved to engage the pin with the teeth of one of the sprockets thus locking the carriage to the chain which moves the carriage against the log and forces it into the wedge assembly thus splitting the log.  A rod extends rearwardly of the lever and passes through an apertured disengaging plate.  The rod has an adjustable stop on the distal end thereof which strikes the plate when the carriage is at the end of its travel thus disengaging the pin from the sprocket at this point.
