Inventor: MATSUYAMA JINSHO
IPC: C23C16/44
Filed: 1987-03-30
Granted: 1995-10-03
Abstract: A method for forming a crystalline deposited film comprises introducing a gaseous starting material for formation of deposited film and a gaseous halogenic oxidizing agent having the property of oxidative action on said starting material into a film forming space in which a substrate having a free surface with a non-nucleation surface (SNDS) with smaller nucleation density and a nucleation surface (SNDL) having sufficiently small area for crystal growth from only a single nucleus and having greater nucleation density (NDL) than the nucleation density (NDS) of said non-nucleation surface (SNDS) being arranged adjacent thereto is previously arranged, thereby effecting contact between said materials to form a plurality of precursors containing precursors under excited state, forming a single crystal on said nucleation surface (SNDL) with at least one precursor of these precursors being as the source for feeding the constitutent element of the deposited film and permitting a single crystal to grow from said nucleus.

Title: Insulated glass skylight assembly
Inventor: BECHTOLD STEPHEN K
IPC: E04D13/035
Filed: 1987-06-30
Granted: 1991-07-16
Abstract: ABSTRACT An insulated glass skylight assembly is provided that is adapted to be mounted to cover an opening in a roof structure. The assembly includes a box-like liner adapted to be mounted adjacent the edge of an opening in a roof structure around the periphery thereof, to surround the opening and to form a wall extending upward from the roof structure.  A swinging window unit is provided which includes an insulated glass insert, an inner supporting frame, and an outer encasing frame.  The insulated glass insert is of a predetermined size and shape to substantially conform to the opening in the roof structure, and the inner supporting frame is adapted to engage and seat on the liner and to support the glass insert.  The outer supporting frame is adapted to be coupled to the inner supporting frame and capture the glass insert therebetween.  The inner and outer frames are located adjacent the wall of the liner and engage the peripheral portion of the glass insert so as to expose a maximum amount of the glass insert overlying the opening in the roof structure, while maintaining minimum exterior dimensions for the skylight assembly.  A first sealing system is positioned between the glass insert and the inner and outer frames to provide insulation and prevent a direct contact therebetween.  A second sealing system is positioned between the engaging surfaces of the inner supporting frame and the liner so as to seal the engaging surfaces therebetween when the swinging window unit is positioned on the liner.  Also, a pivotable interconnection between the swinging window unit and the liner is provided, so as to permit shifting of the swinging window unit between an open and closed position with respect to the liner.

Title: Process and dope for forming asymmetric gas separation membranes having graded density skins
Inventor: KESTING ROBERT E
IPC: B01D67/00
Filed: 1987-08-14
Granted: 1993-08-31
Abstract: 36-21(5441) PROCESS AND DOPE FOR FORMING ASYMMETRIC GAS SEPARATION MEMBRANES HAVING GRADED DENSITY SKINS Abstract of the Disclosure A process and dope are disclosed for forming high free volume, asymmetric gas separation membranes having graded density skins and macrovoid-free mor-phology from a solvent system comprising a Lewis acid, Lewis base, and a Lewis acid:base complex which dissolve hydrophobic polymers. The dopes have high total solids, high viscosity and low coagulation (g) values which enhance rapid gelation without the formation of macrovoids and which minimize densifi-cation. The dope solvent system complexes are readily disassociated by the coagulation medium and the component molecules are miscible in the medium which provides for rapid desolvation of the formed membrane thus providing a membrane having low residual solvent retention.

Title: Process for the formation and drying of filter cake
Inventor: BOTT REINHARD
IPC: B01D33/62
Filed: 1987-08-25
Granted: 1992-05-26
Abstract: ABSTRACT OF THE DISCLOSURE      In a process for the formation and removal of moisture from porous filter cake comprising individual solid particles on a filter medium by means of a fluid acting on the filter cake and which has a pressure difference compared with the filtrate behind the filter medium, the filter cake is economically freed from the suspension liquid by means of a differential pressure without or with only an insignificant fluid flow through the filter medium, in that a filter medium with a higher capillary intake pressure for the fluid than that of the filter cake is used and that a filtration pressure is applied to the fluid which is higher than the capillary intake pressure of the filter cake and equal to or smaller than the capillary intake pressure of the filter medium. Through increasing the intake pressure of the filter medium to above that of the filter cake, the penetration of the expelling fluid into the filter medium is prevented and consequently the filtration pressure is maintained, so that this brings about economic filtration.

Title: Method and apparatus for smoothly stopping an elevator car at a target floor
Inventor: CAPUTO WILLIAM R
IPC: B66B1/40
Filed: 1988-07-14
Granted: 1992-02-11
Abstract: ABSTRACT OF THE DISCLOSURE A method and apparatus for smoothly stopping an elevator car at a target floor in an elevator system which utilizes a speed pattern to control car speed via a speed feedback control loop.  When the elevator car reaches  a predetermined slowdown point relative to a target floor, the  speed  pattern  is  changed  towards  a  predetermined minimum  non-zero  value,  with  the  non-zero  value  being selected to insure that the car will reach the floor in the event of error in the arrangement used to change the value of the speed pattern.  The  speed pattern value is then independently forced to  a value indicative  of zero car speed in response to a detector which detects the actual presence of the elevator car as it reaches a predetermined small dimension from the target floor, to stop the car at floor level, before a holding brake is applied.

Abstract: ADAPTIVE FILTRATE FLOW CONTROL SYSTEM USING   CONTROLLED REDUCTION IN FILTER EFFICIENCY                 ABSTRACT OF THE DISCLOSURE     The efficiency of a blood plasmapheresis filter is purposefully reduced at low input blood flow rates so as to prevent possibly excessive hematocrit which may make it difficult or impossible to handle the resulting blood cell concentrate (e.g., for infusion purposes) and/or which may cause accompanying red cell damage. Where filter efficiency is a function of rpm of a spinning  element, such controlled reduction may be achieved by simply controlling spinner rpm as a function (e.g., linear over at least some range) of the input blood flow rate.

Abstract: ABSTRACT OF THE DISCLOSURE An optical fiber moisture sensor is prepared by coating an optical fiber with a thin film of plasma polymerized hexamethyldisiloxane and ammonia, approximately 1-2 um thick.  The light transmission characteristics of such a coated optical fiber change as a function of moisture conditions in an environment to which the coating is exposed.  Accordingly, the coated optical fiber may be utilized for sensing changes in moisture conditions in an environment by being placed in the environment, causing light to be transmitted through the fiber and detecting changes in the light transmitted through the fiber as a function of the moisture conditions in the environment.
