Abstract: Abstract of the Disclosure A building of generally spherical configuration has a lower portion and an upper portion and includes an outer skin of first triangular panels and an inner skin of second triangular panels.  Substantially all of the panels are light transmitting, and may be made of glass.  Partitions extend from the lower to the upper portion of the building between the two skins and divide the inter-skin region into a plurality of sectors running from the lower to the upper portion of the building.  Particulate insulative material is provided, along with apparatus for selectively filling the sectors with insulative material by delivering insulative material to the upper ends thereof, and to selectively empty the sectors of insulative material by withdrawing insulative material from the bottom ends thereof.  The building can be controlled in such a way as to allow open or empty sectors to track the sun in the winter, thus maximizing solar heating, and to face away from the sun in hot weather, thus minimizing overheating while allowing light entry.

Title: Storage vault and method
Inventor: LINDQUIST THOMAS R

Filed: 1987-11-30
Granted: 1992-02-25
Abstract: STORAGE VAULT AND METHOD                   ABSTRACT OF THE DISCLOSURE                A storage vault includes a steel inner tank entombed within a reinforced concrete outer tank with a thermal insulating spacer layer between the two.  The outer tank includes a liquid barrier to trap leaks from the inner tank.  The spacer layer is made of a material which liquifies upon contact with the liquid stored within the inner tank. This permits the spacer layer to fill the space between the inner and outer tanks while permitting any leak to collect at a liquid collection region between the two.  The leaked liquid collection region can be monitored through a leak detector tube.  Since the spacer layer can substantially fill the space between the inner and outer tanks, pouring the concrete outer tank is simplified and thermal insulation is maximized.

Abstract: A sound synthesizing method and apparatus  for producing synthesized sounds having a property similar to the  property of  natural  sounds  emitted  from a  natural acoustic tube having a variable cross-sectional area.  The natural acoustic tube is replaced by a series connection of a plurality of acoustic tubes each having a variable cross-sectional area.   The acoustic tube series connection is replaced by an equivalent electric circuit connected between a power source circuit and a sound radiation circuit.  The equivalent electric circuit includes a parallel connection of  first  and  second  electric  circuits  equivalent  for adjacent first and second acoustic tubes of the acoustic tube series connection.  The first electric circuit includes input and output side sections each including a propagated current source and a surge impedance element having a surge impedance inversely proportional to the cross-sectional area of the first acoustic tube.   The second electric circuit includes input and output side sections each including a propagated current source and a surge impedance element having a  surge  impedance inversely proportional  to the cross-sectional area of the second acoustic tube.  A value for  the  current  flowing  in  the  radiation  circuit  is calculated  to  produce  a  synthesized  sound  component corresponding to the calculated value.  Thereafter, similar calculations are  repeated at uniform time  intervals  to produce a synthesized sound.

Abstract: In a method for planarizing an insulating layer, the height of steps in a layer of insulating material are reduced while tapering side walls of the steps by forming a layer of sacrificial material between the steps and etching the insulating material and the sacrificial material in a low pressure plasma comprising reactive ions and facetting ions. This method combines many of the advantages of Resist Etch Back (REB) and argon facetting techniques while reducing the deleterious effects of macroloading and microloading.

Granted: 1993-04-27
Abstract: METHOD AND APPARATUS FOR AUTOMATICALLY CONTROLLING PRESSURE IN FLUID-ACTUATED SYSTEMS                 Abstract of the Disclosure The invention provides a method and apparatus for controlling the level of clamping pressure applied by a clamp (14) to a load (16). A pump (20), whose output is controlled by a normally open valve (34), establishes an initial level of clamping pressure. Through the use of a number of controllable fluid discharge means (50, 52, 54), this pressure is automatically increased in increments depending upon the resistance of the load to the clamping pressure exerted. In apreferred embodiment, the controllable fluid discharge means include discharge cylinders (58, 70, 90) that contain predetermined volumes of fluid dischargeable by free-floating pistons (62, 82, 92) residing therein. The outputs of the discharge cylinders are controlled by pressure-responsive valves (72, 92) to produce the desired relationship between clamp pressure and load rigidity.

Abstract: TITLE METHOD OF GENE MAPPING         ABSTRACT           The method of described characterizes each DNA segment to be mapped by cleaving it to produce DNA fragments which are then end labeled with a reporter(s) specific to the end nucleotides of each fragment.  The labeled fragments are again cleaved to produce short fragments which are separated according to size.  The short fragments are analyzed as to reporter identity and size which is indicative of the character of each fragment.  By derivatizing the cleaved ends of the primary cleaved fragments, the labeling may be delayed until  the second cleavage. Prior to labeling the derivatized fragments, all underivatized fragments are removed, the derivatized fragments being immobilized.

Abstract: ROTARY TILLER APPARATUS          ABSTRACT OF THE DISCLOSURE             A rotary tiller device for tilling around trees and  other  similar obstacles  comprises a rotary tilling  head with  a    plurality  of  tines  extending  slightly  outwardly, downwardly and forwardly from a support which rotates around a vertical  axis of  the head.   A central  plate rests upon the ground  and  defines  a  tilling  depth  of  the  tines.  A  cover prevents the support damaging the tree.   A mounting system for mounting  the unit on the belly of a yard tractor includes a pair of rails mounted in place of the removed belly mower and a hydraulic  fluid reservoir tank which slides into position on the rails and defines a support for the tiller head.  A linkage between the tank and the tiller head includes a six-bar lever system  mounted  upon  a  pivotal  plate.   The  lever system is actuated by a hydraulic cylinder which drives the tiller head in a straight line outwardly and slightly forwardly of a line at right angles to the side of the tractor and in a plane which is generally horizontal and is defined by the plate member at the end of the tank.  The straight line actuation of the lever system enables the tiller head to be readily manouevered around trees  in a weeding  action while  the  tractor  continues  in a constant direction.

Abstract: ABSTRACT          The invention is a method and a machine for cutting a swim-bladder from a spine of a fish after the spine has been removed from the fish or the fish has been flitched.  The method includes laying the spine upon a guiding wedge, which perforates the swim-bladder and cuts it open, moving the spine forward toward a motor driven knife, which cuts the swim-bladder free from the spine.  The machine includes a cantilever beam which guides the spine toward a horizontal motor driven knife.  The guiding wedge is fastened into the frame of the machine.  Its lower part is elastic in order to be able to cut different sizes of swim-bladders. The forward motion is powered by a conveying wheel, belt or arm, above the guiding wedge. A single conveying wheel has a rift for the crest of the spine. Two conveying wheels are spaced for the crest.  The conveying wheel has spikes for grasping the spine and increasing the friction against it, thereby increasing the conveying force.  The guiding wedge has a tip, to perforate the swim-bladder, and a cutting edge for cutting or tearing a hole into the backmost and foremost ends thereof.  To prevent accidents, the conveying wheel and knife are both surrounded by a screen.
