Abstract: HYDROMECHANICAL FUEL CONTROL WITH INDEPENDENT ELECTROMECHANICAL INTERFACE                        ABSTRACT    Fuel flow to a gas turbine engine is controlled in response to power lever position and CDP.  Fuel is supplied to the engine through three fuel flow regulating circuits which are in parallel.  In one of these circuits there is a valve which establishes a minimum fuel flow which decreases with increasing power lever advance.  In a second circuit there is a valve which modifies fuel flow in response to CDP.  In a third circuit there is a valve which modifies fuel flow in response to CDP and receives fuel from a valve which opens with increasing power lever advance.  The fuel control system includes a low power sensitive torque motor which may be activated to increase the pressure drop across the three circuits whose flow thus increases proportionally.  Normal engine operation is obtainable without the use of the torque motor which provides an interface to an electronic control unit which senses various engine and ambient parameters and activates the torque motor in order to modify fuel flow accordingly.

Abstract: ABSTRACT           The invention relates to a process for the manufacture of objects from water-hardened materials, reinforced with one or more reti-culate webs, one over the other, which webs have been obtained by stretching, fibrillating and spreading of a film of organic polymeric material, by continuously supplying one or more reticulate webs, con-tacting them with a water-hardening material and water, thus forming a composite material, and shaping and hardening this material. This is obtained according the invention in that: a. one or ore reticulate webs, one on top of the other, are continuously supplied and laid on a carrier; b. the reticulate webs are folded zig-zag on this carrier; c. the folded network is continuously transported in a direction vir-tually normal to the direction in which the reticulate webs are supplied; d. subsequently, the folded network is contacted, directly or indirectly, with a water-hardening material and water.       The rate of supply of the reticulate webs to be folded and the rate of discharge of the folded networks is such that the angle between two successive folded sides of the reticulate webs is between 1/2° and 120°, in particular between 50° and 90° and most in particular between 1° and 20°. Reticulate webs are applied to one side or to both sides of the resulting folded network, which webs have been stretched and fibrillated longitudinally and in the transport direction and are supplied in the direction of motion of the folded network, and in particularly, at only one of the two sides of the resultant folded network, reticulate webs stretched in the transport direction are applied, and at the other side only one or two of such webs. The resulting folded network packages are integrated to a whole by welds at the sides and passed between two rollers prior to being con-tacted with a water-hardening material.

Abstract: ABSTRACT A seal for limiting access of bacteria through a side arm of a stopcock such as that used in apparatus for monitoring pressure in a human blood vessel. The seal has a generally cylindrical body, an open end of which slides over the side arm.  A portion of the body seals against the side arm exterior wall.  The other end of the seal forms a cap through which a syringe nose may penetrate to establish fluid communication between the syringe and the side arm lumen.  The interior of the seal body includes a recess for a Luer lock fitting which may exist on the end of the side arm, and an annular spacer projecting from the inside of the body to provide a surface against which the end of the side arm can abut to prevent the inserted syringe nose from bottoming on the end of the stopcock arm during use.  A slit in the capped end of the seal facili-tates insertion of the syringe nose.  The slit is sur-rounded by a recess to guide the syringe nose into the slit.  The inside of the cap is provided with an addi-tional dome of material to increase the sealing contact between the cap and the syringe nose and so that line pressure in the side arm will help keep the slit closed tight around the end of the syringe nose.  A further recess is provided in the seal body adjacent the inside of the cap to receive the material displaced when the syringe nose penetrates the cap.

Abstract: Abstract of the Disclosure A traveling hopper feed delivery system is disclosed. The system includes hoppers which carry loads of feed past elongated feed-receiving troughs.  These troughs are located adjacent poultry-retaining cages.  Auger distributor conveyors carried by the hoppers draw the feed from each hopper bottom and urge it toward each feed trough.  Delivery tubes depend from the auger conveyors for directing limited amounts of feed from the conveyors to each trough.  Return means re-turn undelivered feed from the distributor conveyors back to the respective hoppers.  Sensors disposed to extend into the troughs sense the amount of feed al-ready present in the troughs, and adjust butterfly valves (located between the feed delivery tubes and the auger conveyors) in response to the sensed height of feed present in the troughs before additional feed is delivered.

Abstract: ABSTRACT:           In a logic circuit arrangement comprising a plurality of sticks formed by series arrangements of transistors which receive the signals to be processed a conductive stick not only has to discharge the output capacitance of the logic output but also other sticks which are not completely conductive, namely up to the first cut-off transistor.  This may result in a very high capacitive load, which substantially reduces the maximum attainable switching speed.  In accordance with the inven-tion an additional transistor is arranged between each stick and the output of the entire logic circuit, which transistor receives a gate voltage such that current flow from the cut-off charge sticks via a conductive stick is prevented or delayed until the output signal of the logic circuit has assumed a value which umambiguously switches over the next output transistor.  As a result of this, a conductive stick only has to discharge the output capaci-tance of the logic circuit arrangement, so that a sub-stantially higher switching speed can be obtained.

Abstract: ABSTRACT OF THE DISCLOSURE           There is disclosed an apparatus which forms and folds a precut pocket patch and sets it in position on a garment panel, ready to be sewn by an adjacent sewing machine.  The apparatus comprises a holding blade on which a precut pocket patch is manually positioned, and a pocket patch-forming and folding assembly located over the holding blade.  The latter and the assembly are vertically movable one with respect to the other and to an underlying garment panel support table.  The assembly includes a forming plate, having a flat underface and a down-wardly-extending rim at its periphery creating a cavity to receive the pocket patch; the latter is clumped and its margin creased by the rim about the edge of the holding blade.  The assembly further carries around its periphery folding blades which move inwardly underneath the holding blade to complete the folding of the pocket patch.  The contour of the holding blade and of the plate cavity corresponds to the desired contour of the folded patch.  The folded pocket patch is pressed down on the garment panel; the folding blades retract outwards, and the forming and folding assembly moves up and the holding blade keeps the patch on the garment panel until the conventional sewing clamp engages the patch, at which time the holding blade is retracted.  The sewing clamp then transfers the assembled pocket and garment panel to the sewing station, ready for sewing.
