Abstract: DUAL REEL RETRACTOR     ABSTRACT OF THE DISCLOSURE        A seat belt retraction apparatus has a single retractor frame carrying reels each having a webbing attached at one end.  The reels each have a pawl and ratchet means for locking each reel to prevent rotation of the reel in the belt extending direction.  Upon application of predetermined force, an inertia type sensing means displaces a common actuating means to simultaneously actuate each pawl into locking engagement with its associated ratchet means to prevent rotation of each reel in a web extending direction.          The preferred actuating means comprises a rotary lifter having a flexible portion for storing energy in the event that its associated pawl bounces on a tip of a ratchet tooth of a ratchet wheel.  The actuating means and inertia means may be located outwardly of the sidewalls of the retractor frame.

Abstract: METHOD AND APPARATUS FOR PUMPING CONCRETE   TO FORM STRUCTURE AT ELEVATED HEIGHTS            Abstract of the Disclosure A  method and apparatus is disclosed for continuously pumping flowable concrete mix to elevated heights for introduction into forms used in the fabri-cation of annular structures such as concrete hyper-bolic cooling towers.  A tower crane is erected in the center of the circle for the hyperbolic structure and concrete conveying piping is provided for raising mix to a lateral conduit carried by a secondary boom sus-pended from the swingable overhead jib of the crane. A pumping unit at ground level forces concrete mix up the vertical piping on the tower and thence through the boom supported conduit for delivery into the form structure.  The jib and thereby the boom suspended therefrom are swingable through an arc of 180° in one direction to cover one half of the form structure and then the jib and boom may be swung in the opposite direction through the remaining 180° arc for introduc-tion of mix into the form structure.  The tower crane is of the type having a climbing cage permitting lift-ing of additional mast units to the top of the stack thereof using the jib as a lifting medium to increase the height of the crane. Corresponding pipe sections on the tower mast units allow delivery of concrete mix to increasingly higher elevations as fabrication of the hyperbolic structure progresses.  The length of the secondary boom and thereby the laterally extending conduit supported thereby may be increased or decreased as necessary to accommodate the changing diameter of the hyperbolic concrete shell during construction.

Abstract: Abstract of the Disclosure A linkage system for actuating the variable vanes and the air bleed valve of a gas turbine engine compres-sor in an intermittent sequence includes a single ac-tuator and a linkage mechanism.  The latter is formed of a first actuating linkage extending to the bleed control valve, a second actuation linkage extending to the variable guide vanes, and an intermediate crank mechanism connected to the first and second actuating linkages and also to the single actuator.  The linkage system is operative to convert the linear motion from the single actuator to multiplane intermittent rotational motion of the actuating linkages extending to the vari-able vanes and the bleed valve of the compressor. When embodied in a military aircraft, the single ac-tuator is preferably disposed above the compressor casing so as to make it less vulnerable to enemy ground fire.

Abstract: Abstract A multiport radio frequency (RF) signal combiner is described for combining three or more RF signals for application to an antenna.  The combiner includes an input port for each RF signal, an output port coupled to the antenna, and a tuning port coupled to a tuning transmission line.  The input ports, output port and tuning port are connected to a terminating element.  The tuning transmission line is terminated by a fixed or adjustable short-circuit impedance for substantially eliminating the capacitive discontinuity created by interconnecting the input ports.  The RF signal combines can be advantageously utilized in any radio system where it is necessary to multiplex the RF signals from three or more transmitters to a single antenna.

Abstract: METHOD OF FABRICATING SEMICONDUCTOR DEVICES USING LASER ANNEALING        Abstract of the Disclosure In the manufacture of VLSI (very large scale integrated) MOS (metal-oxide-semiconductor) circuits, a polysilicon gate is deposited on an oxide layer overlaying a silicon substrate.  Ideally, the polysilicon gate is made extremely small and with sharply defined vertical boundaries.  The invention proposes depositing a polysilicon layer, covering a region of the layer with an antireflective coating, and laser annealing the layer.  Laser radiation is absorbed to a higher level by the coated region than elsewhere and consequently the polysilicon layer in this region melts and recrystallizes into large grains.  The polysilicon layer is then etched using etch conditions ensuring preferential etching of unrecrystallized polysilicon in comparison with recrystallized polysilicon.  Consequently, except at the coated region, the polysilicon is etched quickly and there is very little undercutting of the gate region.  Preferential etching methods based on differing dopant levels in polysilicon are known but do not produce the sharp edge definition enabled using the present process.     - i -

A method of forming an open pouch comprising the steps of continuously pulling an elongated web of pouch forming material at a constant speed along a pouch making path which extends continuously through a web coating station, a web collating station, an electron beam curing station and a web cutting station.  A pattern of a coating is applied to a first surface of a first continuous web of pouch forming material as it is pulled continuously through the web coating station to render the interface bondable at a seal line and non-bondable in the area of the storage compartment when subjected to electron beam radiation.  A second web is directed into a face-to-face relationship with the first web in the collating station and irradiated with E.B. radiation to bond, without heat distortion, the bondable areas of the web at the interface while leaving the non-bondable areas free from securement and the pouches are cut from the webs by severing along transverse cut lines.   1.1
