Title: Escalator
Inventor: WEHRLI HENRY A III
IPC: B66B25/00
Filed: 1979-09-27
Granted: 1981-10-06
Abstract: ABSTRACT OF THE DISCLOSURE An escalator for transporting passengers between upper and lower landings.  The escalator includes a fly-wheel,  an  overrunning clutch,  and  a  fail-safe  friction brake.   The overrunning clutch and brake, when actuated applies a braking torque only when the escalator is moving such that it would transport passengers from the upper to the lower landing.   The inertia of the flywheel and the braking torque of the brake are predetermined to provide the desired range of deceleration, when the escalator stops in either travel direction, regardless of load.

Abstract: Abstract of the Disclosure Information-recording process in which heating e.g. using a pulsed laser, produces recording marks in the form of areas of surface relief on the surface of a recording medium.  The medium is selectively producible in different density states by cooling it at a selected cooling rate from the molten state, and can be switched between said states by controlled exposure to the heating, thus permitting repeated recording and erasing on the medium.  This permits very small marks of less than 1 micron diameter to be produced using a diffraction-limited spot of light, and as surface relief of high aspect ratio can be obtained at low power levels, it is possible to achieve high packing densities and high signal to noise ratio at low energy costs.

Abstract: TITLE OF THE INVENTION                        INDUCTION HEATING COIL     ABSTRACT OF THE DISCLOSURE     An improved flat induction heating coil for a cooking apparatus of the type in which an electrically conductive cook-ing utensil is heated according to the principle of electromag-netic induction.  To provide a substantially uniform magnetic flux density distribution in the induction coil constituting a part of the cooking apparatus, and,hence, a uniform temperature dis-tribution across the bottom of the cooking utensil, a refractory insulating material is wound adjacent inner turns of the coil to provide a comparatively larger winding pitch for said inner turns than for outer turns.  This arrangement makes for a flattened temperature profile and eliminates an unevent cooking of food.

Abstract: POCKET CONSTRUCTION         ABSTRACT OF THE DISCLOSURE                 In a method of constructing pockets, a pocket blank is preferably folded first along both longitudinal edges, and then transversely so that the edges are inside the two resultant pocket panels.  The inner pocket panel is adhesively secured to the inside of a garment, followed by formation of a slit of uredete mined shape in the adhesive connection therebetween. The edges of the slit are then folded back and adhesively secured to produce a pocket slot.  Preferably, a pocket welt is secured next across the bottom of the slot.  If desired, another welt or a pocket flap can be secured across the top of the slot followed by placement of a facing strip thereover.  Stitched bar tacks are then provided adjacent the slot, after which the pocket panels are closed and sealed to complete construction of the pocket.  In another embodiment, a pocket blank is positioned beneath a pocket opening formed in the garment panel.  The lower edge of the opening is then folded back and adhesively secured to one end of the pocket blank.  If desired, a stitch can be added to reinforce interconnection of the garment and pocket blank.  A facing strip is attached near other end of the pocket blank so that the strip covers the pocket opening after the pocket blank is transversely folded and sealed to complete construction of the pocket.

The outputs of the square function ROM's are then combined and scaled to effect a square by parts of the applied input value, C.  A pair of such arithmetic devices may be advantageously combined to economically effect the product AB of two values, A and B, in the manner of a quarter square multiplier.

Abstract: ABSTRACT OF THE DISCLOSURE    A seismic method for mapping horizonal fractures in the earth resulting from the application of fluid pressure, at a selected point, at a selected depth, in the earth, comprising the steps of creating a seismic wave in the earth over the expected position of the fracture, and detecting the seismic waves reflected upwardly at a reflecting interface, at or near the fracture, at each of a plurality of seismic sensors, in at least one radial array.  The received signals are recorded for each of two conditions:  a first case, when the fracture is pressurized, and filled with fluid, and the roof of the fracture is separated from the base of the fracture; and a second case when the fracture is depressurized, and the roof of the fracture rests on the base.  Some sensors will show a different character of reflection signal in the two cases.  For these sensors the points of reflection are within the outer perimeter of the fracture.  For the other sensors, which show relatively no change in character of reflection signal, the points of reflection are outside of the outer perimeter of the fracture.  The process is repeated for both compressional and shear seismic sources, and the electrical signals are compared for compressional and shear sources and for pressurized and depressurized fracture.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for connecting the turbine blades of a turbine having a plate-shaped member provided at the radially outer end of each turbine blade and extended substantially at a right angle to the longitudinal plane of the turbine blade.  The plate-shaped member is pro-jected from the leading and trailing edges of the turbine blade, and is provided with through bores formed in each projected portion.  Connecting members having cylindrical pins or the like projections are disposed between two adjacent turbine blades in such a manner that the projections are rotatably received by respective through bores.  Namely, one of the connecting members is con-nected to the plate-shaped member of the leading edge of the turbine blade while the other connecting member is connected to the plate-shaped member of the trailing edge of the preceding adjacent turbine blade.  The con-necting members are disposed such that they partially underlie the plate-shaped members of the adjacent turbine blades and that they make contact with each other during the running of the turbine thereby to restrict the untwisting of the turbine blades while attaining a vibration damping effect.
