Patent EP-0264644-A3 (EP)
IPC: H04M9/00
Filed: 1987-09-21
Abstract: Die Erfindung betrifft eine Schaltungsanordnung zur Nach­
bildung des NSI-Kontaktes mittels der elektronischen Halte­
schaltung (H) in einem über die Teilnehmerleitung gespeisten 
Zweiwegefernsprecher (55).  
     Die Aufgabe besteht darin, die Halteschaltung (H) in einfacher, 
wirtschaftlicher Weise für die Funktionsweise des NSI-Kon­
taktes umzugestalten, wobei galvanische Trennung von Leitung 
und Sprechschaltung, Integrierbarkeit und schaltbar mit 
Tasten eines üblichen Tastenblockes gewährleistet sein 
müssen.  
     Dies wird erreicht, indem der in der Halteschaltung (H) zum 
Abschließen der Teilnehmerleitung mit einem Lastwiderstand 
versehene Strompfad zwischen den Adern der Teilnehmerleitung 
im Takt der Wahlimpulse durchgeschaltet und aufgetrennt 
wird, wobei jedoch der Lastwiderstand (RL) überbrückt wird. Das 
Überbrücken erfolgt mit Transistoren (T1,T3,T4), die über einen 
Transistor-Optokoppler (T2,T5) durch den Mikroprozessor (M) 
gesteuert werden.  
     Die Anwendung erfolgt bei Zweiwegefernsprechern.

Title: Bar vent for downhole tool
IPC: E21B34/10
Filed: 1987-02-10
Abstract: A low actuation pressure bar vent (10) for use in a tool string having low pressure therein, includes a body portion (12) and a piston (14) slidingly disposed in the body. The piston and body define a first cavity (68) therebetween and a second cavity (70) therebetween, spaced from the first cavity. The body further defines a plurality of transverse ports (58) therethrough providing communication between a body central opening and a well annulus. When in a closed position (Figure 1), the piston sealingly closes the ports. In a first embodiment, the first cavity has a spring (16) disposed therein. The body also defines a second plurality of ports (72) therein providing fluid communication between the first cavity and the well annulus. Pressure in the well annulus and the spring bias the piston toward an open position uncovering the ports. In an alternate embodiment, a pressurized gas biases the piston. The second cavity (70) is filled with a fluid such that movement of the piston is prevented. A break plug (88) is positioned in the piston and includes a shearable portion (92), which when sheared, allows the fluid in the second cavity to be released to the tubing string. The biasing force moves the piston to the open position, displacing the fluid from the second cavity. During assembly, an assembly plug (104) temporarily holds the piston closed.

IPC: B24B31/06
Filed: 1987-02-27
Abstract: The invention relates to a finishing apparatus in which 
a workpiece and finishing media are agitated together in 
a finishing chamber. Hitherto, vibratory workpiece 
finishing apparatus have comprised an annular finishing 
chamber which is generally satisfactory for the mass 
finishing of small workpieces, but will not normally 
facilitate the finishing of relatively large items. 
The invention provides a finishing apparatus for a 
workpiece comprising a cylindrical container having a 
bottom wall 56 and an upstanding peripheral wall 54 
defining therebetween a finishing chamber 57 for the 
workpiece and finishing media and which is uninterrupted 
between diametrically opposite wall portions. Means 64 is 
provided for imparting vibratory movement to the container.

Title: Methods of and apparatus for seeking a target address on a record medium
IPC: G11B27/10
Filed: 1987-05-05
Abstract: A method of and an apparatus for seeking a target address having an appended error check code are disclosed. When seeking a target address on a record medium (1) on which the recorded data are divided into a plurality of blocks in correlation with an address for each block and an error check code for each address, the error check code to be appended to the address is formed from the target address. The target address and the error check code derived from the target address are compared with the address having the error check code reproduced from the record medium (1). When the result of such comparison has revealed that the error is within the symbol or bit number that can be corrected by the error check code, the address read from the record medium (1) is determined to be the target address.
Patent EP-0259143-A3 (EP)
IPC: G01S7/41
Filed: 1987-09-01
Abstract: A series of discriminants may be applied to a multi-dimensional 
look up table with a view to making a decision on what the combination 
of discriminant values represent. The discriminants might be say 
phase, amplitude and polarisation of a radar return from a possible 
target. To reduce the number of look-up table dimensions and render 
the decision process more efficient, the discriminants are subjected 
to spectral decomposition to produce a reduced number of output 
discriminants which nevertheless may, given certain maximum entropy 
optimisation concepts, contain all the information required for the 
decision.

Patent EP-0309682-A3 (EP)
IPC: G03F7/00
Filed: 1988-07-28
Abstract: The invention provides a method for forming a photoresist 
mask on a substrate resistant to reticulation during plasma 
etching. The method comprises the steps of forming an imaged and 
developed photoresist coating over an integrated circuit 
substrate where the photoresist contains an essentially 
unreacted acid activated cross linking agent, and subjecting 
said substrate to an etching plasma in a gaseous stream that 
contains a Lewis acid. Contact of the surface of the photoresist 
film with the Lewis acid causes cross linking of the surface of 
the photoresist film during plasma etching with the formation of 
a reticulation resistant surface layer.

Title: Minimum complexity vibration damper
IPC: F16F15/123
Filed: 1984-12-13
Abstract: A minimum complexity vibration damper that 
integrates the function of structural components and 
reduced lag in a vibration damping system. This assembly 
utilises presure plate formations for spring seats and the 
configuration of the pressure plate (56) for spring 
retention. The reactor plate (62) or hub is designed to 
concentrate spring unit loading on the hub and away from 
other components of the assembly, thereby decreasing lag. 
The reactor plate (62) has a pair of outwardly curved 
arcuate channels (67) acting as spring pockets and 
separated by a pair of diametrically opposed inwardly 
offset drive straps (69). A pair of diametrically opposed 
inwardly offset triangular spring abutments (59) is 
provided on the pressure plate.

Title: Acoustic apparatus
IPC: H04R3/00
Filed: 1989-03-30
Abstract: Disclosed is a compact, wide-range acoustic 
apparatus which can perform lower bass sound 
reproduction and is free from noise or distortion 
components. Spatially separated first and second 
chambers are formed. The first and second chambers 
communicate with each other through a port, so that the 
first chamber and a resonance port constitute a 
Helmholtz resonator. An open port is formed in or a 
passive vibrating body is arranged on the outer wall 
surface of the second chamber, so that the second 
chamber and the opening or the passive vibrating body 
constitute an essential low-pass type acoustic filter. 
A vibrator is attached to the outer wall surface of the 
first chamber, so that the Helmholtz resonator is 
driven at the inner surface side of the vibrating body 
of the vibrator, and an acoustic radiation is directly 
performed from its outer surface side. The vibrator is 
driven to cancel an air counteraction from the 
resonator when the Helmholtz resonator is driven. A 
cutoff frequency of the acoustic filter is set to be 
higher than a resonance frequency of the Helmholtz 
resonator and to be lower than the open duct resonance 
frequency of the resonance port.

Title: Modifying pattern-matching networks
IPC: G06F9/44
Filed: 1989-11-10
Abstract: A pattern-matching network is merged with a pre-existing RETE network 
without recompiling the whole network, while still matching existing 
data. Permanent, temporary , full and partial merging operations are 
described, depending on the origination of match patterns among LHS, on 
demand (procedural programming), or top level. The merge process 
combines functionally identical nodes from the networks for reducing 
the number of nodes in the resulting network. The merger process 
produces so-called alpha and beta synapse nodes; alpha synapse nodes 
have pointers to top nodes, while beta synapse nodes have pointers to a 
drain node, which is a node in the grafted RETE portions of the 
resulting network and to source memory nodes in the pre-existing RETE 
network. The algorithm for obtaining a set of synapse nodes without 
duplication of any logic connecting paths is described. The synapse 
nodes are used in updating a grafted network, also can be a suspended 
portion, upon completion of the merger. Two network updating algorith­
ms are presented.
