Abstract: A mould 13 which may be of graphite, ceramic 
material, or metal is formed with an internal surface 14 
accurately machined to the required shape of the surface 
of the rotary dresser which is being formed.  
     Diamond particles 15 are then adhered to the 
surface 14 by any suitable adhesive.  
     A metal surfacing powder is then applied to build 
up a metal layer 16 by means of an arc plasma spray 
surfacing gun 20 to melt the powder particles and a high 
velocity gas flow to propel the particles onto the 
diamond coated layer.  
     A layer of a low melting point dimensionally 
stable alloy may be cast on top of metal layer 16 onto 
the internal bore. The mould 13 is then removed and the 
external surface accurately ground to final form. A 
supporting steel core may be added.

Title: Implantable gas-containing biosensor and method for measuring an analyte such as glucose
IPC: G01N33/487
Filed: 1986-09-17
Abstract: An implantable biosensor and method for sensing products, such as hydrogen peroxide, generated from an enzymatic reaction between an analyte, like glucose, and an enzyme in the presence of oxygen. The implantable biosensor is equipped with an enclosed chamber for containing oxygen and can be adapted for extracting oxygen from animal tissue adjacent the container. The reservoir of oxygen contained in the enclosed chamber is supplied to the enzymatic reaction from the side of the membrane opposite the enzyme. The enclosed chamber is designed to be impermeable to substances, like liquid and cells, that possibly can interfere with the supply of the oxygen permeating through the membrane to the enzymatic reaction. Also, the implantable biosensor is designed to optically or electrically sense products generated from the enzymatic reaction which serve as a function of the analyte.

Title: Programmable sound reproducing system
IPC: H04R3/02
Filed: 1986-10-07
Abstract: In a hearing aid system, selected optimum parameter values are programmed into an electronically erasable, programmable read-only memory (EEPROM) (84) which supplies coefficients to a programmable filter (64) and amplitude limiter (67) in the hearing aid so as to cause the hearing aid to adjust automatically to the optimum set of parameter values for the speech level, room reverberation, and type of background noise then obtaining. The programmable filter may be a digital equivalent of a tapped delay line in which each delayed sample is multiplied by a weighting coefficient, and the sum of the weighted samples generates a desired electro-acoustic characteristic; or a tapped analog delay line in which the sum of the weighted outputs of the taps generates the desired characteristics. Acoustical feedback is reduced by an electrical feedback path in the hearing aid which is matched in both amplitude and phase to the acoustic feedback path, the two feedback signals being subtracted so as to cancel each other. Alternatively, a single filter in the forward path may be used for this purpose with a transmission characteristic equivalent to that of the programmable filter in the forward path plus the electrical feedback path. Also, the relative speech-noise content in the signals from the hearing aid microphone is sensed and binary words are generated and supplied to the programmable filter for selecting from memory a set of delay line tap coefficients that are effective to impart to the filter the appropriate frequency response for the specific environmental noise condition being detected.

Patent EP-0219490-A3 (EP)
Title: Mechanical sealing unit
IPC: F16J15/34
Filed: 1986-10-17
Abstract: The object of the invention is a shaft sleeve and/or cartridge sliding ring seal, a spring package for such a shaft sleeve and/or cartridge sliding ring seal and the use of a spring package in shaft sleeves and/or cartridge sliding ring seals. In such shaft sleeve and/or cartridge sliding ring seals, the sealing element 8 consists preferably of non-elastomer material, e.g. graphite, and is loaded in the axial direction by at least one spring 5, 6. In the installed state, the at least one spring 5, 6 provided is held in the compressed position by a retaining element 9. The essential feature in this case is that the retaining element 9 loses its retaining force at a temperature higher than the installation temperature, so that the retaining element loses its retaining force when it is subjected in use to a temperature higher than the installation temperature and the spring or springs 5, 6 can expand and thus come into a position in which they exert a pressure on the sealing element 8. <IMAGE>

Patent EP-0272561-A3 (EP)
IPC: G06Q10/10
Filed: 1987-12-11
Abstract: Apparatus for distributing the processing of data across a 
plurality of loci of control (109) which are connected by 
a mail system (107). The apparatus includes a package 
(104) which contains files of various types (103) and a 
route (105) specifying the order in which the package is 
to be circulated among the loci and the processing to be 
done at each locus. Each locus includes programs (208) 
executable by users which can manipulate the contents of 
the package. The programs automatically take the type of 
file being manipulated into account. The manipulations 
include modifying the unexecuted portion of the route. 
Each locus further includes a process (215) which executes 
the route as modified, a process (225) which tracks the 
package and receives control commands, and a process (229) 
which handles errors detected by the other components or 
by users. The tracking processes maintain data bases 
(227) for locating the package. When a user or the error 
handling process enters a control command at one locus, 
the tracking process at that locus uses the data bases to 
locate the package and send the control command to the 
locus currently processing the package. The route 
executing process checks with the tracking process and 
executes any control command before it sends the package 
to the next locus.

Patent EP-0268355-A3 (EP)
IPC: H01S3/067
Filed: 1987-09-17
Abstract: An optical communications system, e.g. a tele­
phone system, comprising means to accept even electrical 
communication signals from transmitting stations, mod­
ulate an optical signal with said signal from the trans­
mitting station (20) and, using time-division-multiplexing, 
provide a resultant optical communication signal to 
a central station which utilizes a frequency-division-­
multiplexing system for handling incoming optical signals 
before passing the optical communication signals on the receiving stat­
ion which utilises time-division-multiplexing means and, where necessary, 
reconverts the optical signal to an electrical communication signal. 
Particular advantages of the system are that it can 
handle and switch a very large number of signals and 
that it can be utilized in a hybrid communications system 
wherein, for example, users of the system can maintain 
conventional electrical entrance wiring (22) and con­
ventional non-optical telephones and yet interface readily 
with optical street lines (26,28) of the system. Part­
icular aspects of the invention are novel modulating 
and signal-selection devices.

Title: Apparatus and method for implementing precise interrupts on pipelined processor with multiple functional units
IPC: G06F9/48
Filed: 1989-04-21
Abstract: An apparatus and method are disclosed for implementing 
the system architectural requirement of precise 
interrupt reporting in a pipelined processor with 
multiple functional units. Since the expense of an 
interrupt pipeline is warranted only for those 
interrupts that occur frequently - specifically, those 
arising from virtual memory management - the apparatus 
utilizes an interrupt pipeline for frequently 
occurring interrupts, and a slower, but much less 
costly, software-based system for precisely reporting 
the remaining interrupts. The software-based system 
is facilitated by an instruction numbering and tracing 
scheme, whereby pertinent information concerning 
executed instructions is recorded as the instructions 
pass through the processor pipeline and potentially to 
other functional units. A software interrupt handler 
may use this information to isolate and precisely 
report an interrupt.
