Title: Charge electrode array for multi-nozzle ink jet  array
Inventor: HOFFMAN ARTHUR R
IPC: B41J2/09
Filed: 1979-04-19
Granted: 1982-07-13
Abstract: ABSTRACT          A charge electrode array for à muiti-nozzle ink jet array is fabricated from alternate layers of stainless steel  and epoxy resin.  The charge electrode  array may be formed by positioning stainless steel tabs in previously grooved nonconductive substrate such as ceramic.  The grooves are spaced sufficiently apart to allow insulating material to be placed between each stainless steel tab.  Alternatively, a stainless steel plate may be bonded to a nonconductive subtract.  Then the stainless steel can be sliced so that insulating material can be placed between each stainless steel strip.  Epoxy fills the gap between tabs or strips forming an insulating layer, An ink drop charging channel through each tab or strip is formed by drilling through the tips of the steel tab- or strips or by cutting U-shaped channels through the tips- of the tabs or strips

Abstract: A  B  S  T  R  A  C  T             The invention provides a particulate sealing material for use in preparing hermetic seals between ceramic and cermet members, which material comprises at least 70 wt.% refractory oxide and minor quantities of non-vitreous additive comprising SiO2, MgO and B2O3. This particulate sealing material is conveniently pressed into the form of a coherent element shaped to suit the particular sealing operation concerned, e.g. the sealing of an open end of a ceramic arc tube to a cermet closure therefor.  The invention also provides a method of sealing a ceramic component to a cermet member by interposing said sealing material between the opposed races of the component and member and applying heat and pressure to sinter the sealing material and achieve a seal between the component and member.  It has been observed that the sintered sealing composition in the completed seal can have a microstructure characterised by flattened refractory oxide-rich islands aligned generally parallel to said races and substantially surrounded and interconnected by non-vitreous material rich in oxides of silicon, magnesium, and boron and said non-vitreous material forming layers thinner than said islands and also aligned generally parallel to said faces.  The invention is of especial advantage in the closure of the second end of a ceramic arc tube containing volatile fill constituents, since the seal can be effected without melting of the sealing material and hence with improved retention of the tube fill constituents.

Title: Vectored interrupts in a cathode ray tube display
Inventor: STAFFORD JOHN P
IPC: G06F13/34
Filed: 1979-11-06
Granted: 1982-10-19
Abstract: ABSTRACT          A cathode ray tube display terminal system includes a central processor subsystem and a number of peripheral subsystems which are all coupled in common to a system bus.  Apparatus in the central processor subsystem receives interrupt request sig-nals from the peripheral subsystems and on a predetermined prior-ity basis modifies an address generated by the central processor subsystem.  The modified address, called a vectored address, points to a firmware subroutine stored in a memory subsystem, also coupled to the system bus, which processes the selected interrupting peripheral subsystem.  Other peripheral subsystems coupled to the system bus generate a single Interrupt signal which is applied to the apparatus in the central processor system.  The highest prior-ity peripheral subsystem generating the single interrupt signal responds to an interrupt acknowledge signal by sending address signals to the apparatus for generating the vectored address.

Abstract: DEHYDRATION EQUIPMENT Abstract Of The Disclosure A rotary drying system for particulate mate-rial includes a rotary dryer of the multiple pass drum construction with a horizontal axis of rotation.  A furnace is coupled to one end and a horizontally dis-posed centrifugal separator of the scroll type is coupled to the opposite end.  A small cyclone separator is coupled to the scroll separator and connected in a closed loop system with the scroll separator for contin-uous recycling air therethrough.  The rotary dryer has essentially the largest vertical dimension and therefore the profile of the system is minimized.  The rotary dry-er is formed with an inner cylinder of a conical taper with a relatively small inlet end and progressively in-creasing passageway diameter to a large discharge end coupled to an intermediate passageway between the inner cylinder and an intermediate constant diameter cylinder. The intermediate passageway continuously expands in cross-section to a final discharge passageway formed by an outer concentric cylinder.  Replaceable wear plate units support one end of the intermediate and inner cylinders for limited relative movement.  The passage-ways are proportioned to establish a volumetric distri-bution for optimum drying characteristic and temper-ature drop to prevent product degradation and to produce efficient drying.

Abstract: ABSTRACT          A  method  for  manufacturing  variable  capacitance pressure   transducers   and   an   intermediate article   of manufacture produced in the practice of this method.  In the method,  a  wafer  or  doped  silicon  or  other  semiconductor material  has portions of the  semiconductor material  removed from  spaced  areas  to  form  a  plurality  of  recesses  in  the surface of the semiconductor material.  The material is doped to enhance its electrical conductivity.  A dielectric material has  one  of  its  surfaces  coated  with  spaced  areas  of electrically conductive material.   The semiconductor material is attached to the coated surface of the dielectric material such that the surface recesses in the semiconductor material are in alignment with the conductive areas on the dielectric material.  This produces a plurality of electrical capacitors suitable for use as pressure transducers.  The capacitance of these transducers is varied as a function of changes in one or more  fluid  pressures  acting  on  the  plates  of  each of  the capacitors, one of these plates being the doped semiconductor material  and  the  other  being  a  conductive  area  on  the dielectric material.  Fluid pressure between the plates may be established during manufacture.   The  intermediate article of manufacture produced by this process may then be cut into a plurality of separate pressure transducers.

Abstract: ABSTRACT OF THE DISCLOSURE   A four-port network for separating signals comprised of two doubly polariz-ed frequency bands for an antenna feeder system in directional or satellite radio operation, wherein a first polarization converter for converting linear polarization to circular polarization, and vice versa, is designed for the lowest inherent ellipticity in the lower frequency band and is connected ahead of a symmetric polarization filter for the lower frequency band, and a second polarization converter which compensates the remaining ellipticity in the upper frequency band is connected between the symmetric-al polarization filter and a further polarization filter for the upper frequency band.  The second polarization converter for compensating the remaining ellipticity in the upper frequency band has a square cross section; for reducing the frequency dependence of the remaining ellipticity but simultaneously increasing the amount of the remaining ellipticity two bevels are arranged in diagonally opposite corners of said square cross section and a dielectric plate disposed between two diagonally opposite corners of said square cross section has the resulting effect that the amount of the remain-ing ellipticity and additionally its frequency dependence are reduced to a minimum.

Abstract: Abstract A security system uses one electronic key that con-tains many key codes of the user to control several different security devices.  Each security device responds to a particular key code or to more than one key code in a master lock system.          The key when energized presents its entire repertoire of key codes to the security device and when the security device senses its corresponding code, access is gained.  The key may or may not be electrically active.  The key may also include mechanical as well as electronic access control.  Each security device contains a stored code and electronically correlates the stored code and input pulse patterns of the key codes.  A large number of key codes are possible without compromise of system security.
