Abstract: ABSTRACT     A control system for power tongs comprises two tongs torque limiters, one of which limits tongs torque to a very low (hand-tight) level;  the other limits torque at full makeup to, for example, 2000 ft. lb.  The hand-tight torque limiter is manually or automatically disabled after the hand-tight level is reached.  The system enables the operator to verify that the threads are properly engaged before applying full torque to the connection.  The tongs have a very high reduction ratio, so that torque rises very slowly and can be more accurately controlled.

Abstract: ABSTRACT OF THE DISCLOSURE            A method of manufacturing a patterned, coloured surface on an object having a surface of relatively low surface absorp-tion when compared to the interior of the object, and the article produced by the method.  The method comprises the steps of first preparing the pattern on the surface of the object by contouring predetermined portions of the surface, so that recesses are cre-ated therein having a substantially greater surface absorption, and subsequently applying to the entire surface including the re-cesses a paint containing dye pigment, solvent, and about 0.5-8%, calculated on the entire quantity of the paint, of inert, non-soluble fine-grained particles having a maximum cross dimension which is substantially larger than the maximum cross dimension of the dye pigment.  The particle sizes of the dye pigment and the inert fine-grained particles are such that (a) the dye pigment is sucked into the surface of the recesses having greater surface absorption while the inert fine-grained particles are retained on the surface of the recesses, and (b) the inert fine-grained par-ticles settle on the surface portions of relatively low surface absorption and are covered over by the dye pigment.

Abstract: Abstract of the Disclosure The invention relates to a range transformation method for transforming the normalized divisor in a division calculation to a range wherein the transformed value differs from one by no more than the quantity 2-n.  The method and apparatus generate the transform multiplier value from a first high order ''q'' digits of the divisor and generate an out-of-range indicator signal from at least those same digits.          The thus generated multiplier value is modified in response to the out-of-range indicator signal when an out-of-range condition is indicated.  The apparatus employs a read-only-memory for enabling the generation of the transform multiplier value without requiring either large table look-up storage or multiplicative functions.  As a result, various division methods requiring an initial transformation to provide a divisor which approaches one in value can be efficiently implemented.

Abstract: Abstract In a voltage regulator for a generating system having a main generator and an exciter, the exciter providing field current to the main generator, it is desirable to provide a maximum current limit on the generator output which also allows the voltage regulator to maintain excitation during a fault condition.  The voltage regulator of the present invention includes a maximum current limit circuit which detects not only a high current condition, but also the number of phases in a polyphase generator output in a fault condition.  The voltage regulator thereby limits the maximum current each type of fault can produce, thus providing highly desirable system characteristics for clearing faults, tripping circuit breakers and prolonging generator life.

Title: Progressive scan display system with correction for non-standard signals

Abstract: ABSTRACT PROGRESSIVE SCAN DISPLAY SYSTEM      WITH CORRECTION FOR NON-STANDARD SIGNALS           In a double scanning receiver including a video speed-up memory with read and write clocks locked to multiples of burst,  visible artifacts tend to be produced when displaying non-standard video signals (e.g., from a VCR, game, computer, etc.) due to skew of the memory clock signals with respect to horizontal sync. Skew artifacts are corrected by delaying (in 95;96,98) the output signal of the memory (50) as a direct function of the read clock skew and as an inverse function of the write clock skew.  The write clock skew is measured (410-426,Fig.4) for each memory read and write cycle. The read clock skew (in latch 66) for the first memory read cycle corresponds to the write clock skew (in latch 64) measured at the start of the first read cycle.  The read clock skew for the second memory read cycle is obtained by adding to the write clock skew measured at the start of the second read cycle a measured half-line period of the video input signal and taking the fractional part of the sum thereof.  The integer part of the sum is detected (68) to initiate the start of the second memory read cycle. The difference (96) between the write skew signal (64) and twice (84) the read skew signal (66) determines the delay imparted to the video signal.

Abstract: ABSTRACT           A fastener device in combination with a sheet having a rectangular opening formed therein for receiving the fastener device in attachment therewith.  The shank has a tool engaging portion and an elongated flange extending across opposite ends of the shank at right angles to the centerline of the shank.  A circular flange is disposed aroudn the shank and in spaced relation to the elongated flange.  A pair of arcuate shaped cam portions are disposed on a surface of the circular flange facing the elongated flange.  The portion of the shank between the circular flange and the elongated flange has a pair of arcuate surfaces and a pair of shoulders.  When the elongated flange is inserted into the rectangular opening and tthe fastener device is rotated in a direction through 90°, the cam portions fall into the rectangular opening thereby locking the fastener in place, and one of the shoulder surfaces of each right-angle shoulder inhibits further rotation of the fastener in the direction of rotation by contacting a side of the rectangular opening, while rotation of the fastener device in the opposite direction is effective to cause the cam portions to move out of the rectangular opening, and continued rotation through 90° is effective to cause the opposite shoulder surfaces of each of the right-angle shoulders to contact an opposite side of the rectangular opening, at which point the elongated flange is removable from the rectangular opening.

Various couplings may be used such that an auxiliary or bolus port (92) delivers infusate directly into the outlet catheter (24) so that medication from the main chamber (22) does not pass through the auxiliary chamber. A combination of double lumen catheters (106) and T-connectors (100) are employed to provide parallel infusion paths.
