Title: Sound reproduction
IPC: H04S5/02
Filed: 1989-01-05
Abstract: A directionality enhancement system converts 
encoded stereo signals on input channels A and B into 
four signals on left, centre, right and surround 
output channels. The input signals on the A and B 
input channels are respectively attenuated as 
functions of the difference of the logs of the signals 
on the A and B input channels to produce first and 
second attenuated signals. The sum and the difference 
of the input signals on the A and B input channels are 
respectively attenuated as functions of the difference 
of the logs of the sum and difference of the signals 
on the A and B input channels to produce third and 
fourth attenuated signals. The signals on A and B 
input channels and the sum and difference of them are 
then combined together with the four attenuated 
signals to produce left, centre, right and surround 
outputs.
Patent EP-0336582-A3 (EP)
Title: Character string processing
IPC: G06F7/24
Filed: 1989-03-16
Abstract: Strings of characters are ordered automatically in a computer 
system by comparing the weights of the characters of each pair of 
corresponding characters in a first and second of the strings of 
characters; comparing the numerical character codes of a first 
pair of the corresponding characters which are determined to have 
equal weights; and positioning a character string having a corre­
sponding character with a lower numerical character code to have 
a predetermined order with respect to the other of the first and 
second character strings when all pairs of corresponding 
characters succeeding the first pair also have equal weights. 
This results in automated alphabetising of character strings 
which is consistent regardless of the order in which the 
character strings are sorted, while retaining the flavour of the 
language conventions when possible, and while providing a 
solution not requiring substantial extra computing power.
Patent EP-0342947-A3 (EP)
Title: Implantable patient-activated fluid delivery device with bolus injection port
IPC: A61M5/142
Filed: 1989-05-17
Abstract: An implantable fluid delivery device (10) for dispensing 
metered amounts of liquid medication when a pump assembly 
within its casing is operated by finger pressure applied 
to a central target zone (54) of the casing's top wall. The 
top wall also includes an injection site (72) spaced from the 
central target zone (54) for use when a bolus of medicament 
is to be injected into the device and delivered directly 
to the patient without passing through the pump assembly. 
The flattened pear shape of the casing and the location of 
the sites for pump activation and refilling on one hand, 
and for bolus injection on the other, facilitate error-­
free use and operation of the device. Although limited 
fluid backup may occur during bolus injection, a valve 
arrangement within the device prevents intermixing of the 
bolus medicament with the liquid medication in the reservoir. 
In a second embodiment, a supporting grid (80) prevents possible 
injury to the backup-restraining valve during bolus 
injection.

Title: Optical card
IPC: G06K19/06
Filed: 1989-11-02
Abstract: In an optical card, a card substrate (30; 212; 
312) has its rigidity which is sufficient to handle the 
card substrate independently. The card substrate has a 
first side (30a; 212a; 312a) which serves as a reading 
side upon which reading light is incident. An optical-­
data recording section (70; 270; 370) includes a light-­
reflective pattern (42; 214; 314). The optical-data 
recording section is arranged on one of the first and 
second sides of the card substrate. Optical data 
incident upon the optical-data recording section toward 
the reading side of the card substrate is recorded by 
the optical-data recording section. A shielding layer 
(34; 216; 316) is arranged on one of the first and 
second sides of the card substrate, for shielding the 
optical-data recording section from a viewer's field of 
view. The shielding layer has its transmission 
characteristic with respect to the reading light, which 
is sufficient to shield light within a visual range and 
to enable reading of the optical-data recording section.

Title: Drum brake
IPC: F16D65/09
Filed: 1990-05-16
Abstract: The present invention involves an 
improvement in a conventional drum brake assembly 
which utilizes a pair of brake shoes separated by an 
adjustable strut. A parking brake lever (4) is pivotally 
attached to one of the brake shoes and when it is 
rotated in a braking direction, causes both brake 
shoes to expand by interacting with the adjustable 
strut. A plate spring (12) attached to a backing plate (1) 
allows the parking brake lever (4) to pass in the braking 
direction after assembly of the drum brake, thereby 
removing slack and properly adjusting the drum brake. 
The plate spring (12) can be displaced from outside the 
drum brake to allow the parking brake lever (4) to pass 
in the opposite direction for disassembly of the drum 
brake.

IPC: B29C63/22
Filed: 1990-04-24
Abstract: A method of manufacturing a vehicle seat cover and bonding the 
vehicle seat cover to a foam bun utilizing a style insert. The style 
insert is formed by taking a breathable cloth fabric and laminating it to a 
sheet of foam material. The composite so formed is then cut to a desired 
styled insert shape and sewn to the vehicle seat cover skirt to form a seat 
cover assembly.  
     The composite, which may include an air impermeable barrier sheet 
or the barrier sheet may be included in the composite between the foam and 
fabric sheets, is positioned on a forming tool having removable style 
inserts, with the cloth side of the composite against the insert. An 
impermeable film is then positioned over the foam side of the insert 
composite and a vacuum drawn between the forming tool and the impermeable 
film to draw the composite down into conformity with the style lines of the 
tool insert. An adhesively coated foam bun is then positioned and pressed 
against the composite on the forming tool. Heat is applied to the forming 
tool to evaporate the film, allowing the adhesive to bond the cover 
assembly to the foam bun and release the composite from the forming tool 
allowing removal of the seat assembly from the forming tool. The edges of 
the skirt are then fastened together or to the underside of the foam bun so 
as to at least partially enclose the bun.
