Abstract: Polyamide resins are disclosed of polymeric fat acids or 
certain dicarboxylic acids derived from a fatty acid and a 
bis(aminomethyl)tricyclodecane. Copolymerized acids or 
diamine or amino acids may be present. Because of the 
greater rigidity of some of the resins in addition to the other 
desirable properties of the polymeric fat acid polyamides, 
more application areas are opened such as the injection 
molded or extruded structural parts and components.

Title: Valve gated probe
IPC: B29C45/30
Filed: 1986-04-10
Abstract: This invention relates to an injection molding system in which melt flows in channels in the outer surface of a heated probe seated in the cavity plate on its way to the gate leading to the cavity. The probe has a tip end in alignment with the gate and the probe is reciprocated between open and closed positions to valve gate the flow of melt to the cavity. According to a preferred embodiment, in a multi-cavity system a number of probes are fixed to a manifold which is actuated to valve gate all of the cavities simultaneously. Hydraulic cylinders are provided to drive the manifold to the closed position, and injection melt pressure acting on the tip ends of the probes is utilized to return them to the open position. Valve gating the heated probes provides the advantage of improved temperature control of the melt in the immediate gate area.

IPC: H04Q3/62
Filed: 1986-01-13
Abstract: With the increasing complexity of facilities offered 
by a modern private automatic branch exchange PABX, there 
is a corresponding increase in the need to supply 
meaningful feedback to the user. There are four main 
areas where information is required. 
   (i) Supplementation of failure tones,    (ii) Indication of facility activation,    (iii) Indication of routing,    (iv) Provision of ancillary information.     
     Currently the majority of the above situations are 
handled by the provision of selected tones. In the case 
of call failure, two tones are used to indicate in excess 
of one hundred different cases of failure during call-up 
or facility activation.  
     The invention utilises voice response messages to 
inform the user of a particular condition. The messages 
may supplement various tones. The voice synthesis module (VSM) 
includes a number of speech synthesis channels (SYN) and a 
speech data library (SL). The module receives a channel 
number and phrase number from software, which are read by 
a CPU during its scanning routine and starts the required 
synthesiser 'speaking'.

Abstract: An improved document track for document processing 
equipment allows bidirectional movement of a document 10 
along the track 12. A castor arm 50 is mounted at its basal 
end on a castoring bearing 48 in turn at the distal end of a 
castor arm support member 46 on a second side 40 of the 
track 12. A self-castoring idler wheel 52 is mounted atop the 
castor arm 50. Maximum angular excursion 81 in a first di­
rection of the castor arm 50 is prevented by a first stop 60 
and in a second direction 82 by a second stop 62. The self-­
castoring idler wheel 52 is urged against a drive roller 16. As 
a document proceeds along the track 12 urged by the drive 
roller 16 so the castor arm 50 moves to one or other of its 
angular extremes 81, 82 to cause the self-castoring idler 
wheel 52 to urge the document 10 down onto the track 12 
regardlessly of the direction of movement of the document 
10 along the track 12.

Abstract: Disclosed is an analytical unit comprising an analytical 
element having at least one reagent layer provided on a 
transparent support and capable of causing a change in 
optical density when a specimen to be assayed is 
drip-applied thereon, and a photometric method capable of 
catching reflected light of the light incident from the 
side of the transparent support, wherein the analytical 
unit contains a conversion processing method in which a 
conversion equation for converting the optical reflection 
density of the light caught by the photometric method into

conversion equation when the optical reflection density is 
converted into the substance density or value of enzymatic 
activity of a component detected.

Abstract: The invention has composition of matter and process aspects. The 
composition of matter aspect relates to compounds selected from the class 
consisting of 
  
and 
 
 
   
     The process aspect involves the use of these compounds to complex with 
and separate a desired selected ion from a multiple ion solution, breaking 
the complex to free the desired ion and recovering the freed desired ion. 
This process can be carried out in these ways: (A) as ligands in a liquid 
membrane phase for selectively and competitively separating desired metal 
ions from mixtures with other ions in a separate source phase and 
transporting these ions to a separate receiving phase, with both of which 
the liquid membrane phase is in interfacial contact long enough to effect 
substantial removal of the desired ions from the source phase and 
transporting them to the receiving phase from which they are recovered, (B) 
as covalently bonded to silica gel supported in a column through which the 
multiple ion solution is first flowed, followed by receiving liquid, and (C) 
 
 
as ligand in an organic liquid filling pores or apertures in the wall of a 
hollow fiber in a bundle of hollow fibers on opposite sides of which flow 
the multiple ion solution and the receiving liquid.

Abstract: Production of a nitrogen gas stream from the waste gas 
from a pressure swing adsorption process separating a raw gas stream 
containing nitrogen, carbon dioxide, and combustible gas including 
hydrogen, into a hydrogen containing product stream and a waste gas 
stream containing carbon dioxide, some combustible gas, and at least 
some of the nitrogen, by catalytically combusting the waste gas 
stream with an oxygen containing gas and removing water from the 
combusted waste gas stream. Carbon dioxide is removed from the 
waste gas stream before and/or after catalytic combustion. To 
reduce the residual oxygen content of the combusted waste gas 
stream, a small amount of hydrogen, e.g. a portion of the hydrogen 
containing product from the pressure swing adsorption, may be added 
to the combusted waste gas stream and the mixture catalytically 
reacted.

Title: Chair with a reclining seat and a backrest support
IPC: A47C9/00
Filed: 1985-09-09
Abstract: A reclining seat support (3) and a backrest support (4) are hinged on a chair frame with a support part (1) via a lever (7) by means of hinges (5, 8). Coupled to the backrest-side end of the seat support (3) is a link chain (15) which is connected at its other end to a slide (20) and a backrest (21). The link chain (15) causes the slide (20) to be moved downwards with the backrest when the chair is reclined. By this means, the pulling-out effect during the transition from the normal position into the reclined position of the lever is eliminated. However, if the chair frame is used as a chair without a link chain (15), although slightly less seating comfort is achieved by the reclining seat support, the expenditure is correspondingly less. <IMAGE>

Title: Logic signal circuit for a releasing relay
IPC: H02H9/04
Filed: 1989-09-14
Abstract: A circuit and method which eliminates the voltage spike 
generated by inductive kick, and generates a signal which is active 
while a relay is being released and for a given period thereafter. 
This signal can be used to power down circuits supplying signals to 
relay contacts, thereby allowing the relay to release without 
current or voltage potentials at its contact, eg. dry switching. 
The generated signal may also be used to disable sensors which might 
give false indications while the relay contacts are switching. In 
telephone line circuits, the generated signal can be used to disable 
the telephone hook switch detector or to power down the battery feed 
circuit feeding the subscriber line. The relay coil energy 
generates a signal which is active while the relay is being 
released. The invention uses a minimum number of components and the 
circuit is adjustable as to how long the generated signal remains 
active after the relay is released.
