Patent EP-0190874-A3 (EP)
IPC: C08G63/181
Filed: 1986-01-29
Abstract: There is disclosed an improved modified polymer suit­
able for use in making hollow containers by conventional 
extrusion blow molding. It is a specific type of end-capped 
and branched polyethylene terephthalate polymer or 
copolymer. In the improvement, (a) the end-cap comprises 
the reacted component of a monofunctional acid having a 
normal boiling point or sublimation point less than above 
200°C; and (b) the monofunctional acid is an aromatic 
monocarboxylic acid having the formula: 
  
wherein R₃ and/or R₅ are/is an alkoxy group containing from 
1 to 10 carbon atoms and the remaining R's are hydrogen. 
The preferred monocarboxylic acid is m-anisic acid. The 
product typically contains few large gels having diameters 
greater than 0.1 mm.
Patent EP-0190933-A3 (EP)
IPC: F16L55/165
Filed: 1986-02-06
Abstract: A device for inserting within an existing pipe to shatter 
the existing pipe and replace it with a new pipe comprises a 
front portion 1 and a separate rear portion 2. The rear portion 
2 includes a hydraulically operated hammer which is kept in 
engagement with a part of the front portion 1 by means of 
tension applied to the rear portion 2 through cables 9, 9A. 
The hydraulic hammer causes the front portion 1 to vibrate 
relative to the rear portion 2, and this vibration causes 
shattering of the existing pipe, whilst the tension applied 
through the cables 9, 9A ensures that the device is driven 
through the existing pipe.

vehicle wheel (1), the wheel (1) being rotatably mounted 
on an axle (2). The fluid suspension system comprises a 
load arm (3), an air bellows (5), and a torque arm (4). 
The air bellows (5) is mounted between the load arm (3) 
and the chassis (6) of the motor vehicle. One end of the 
load arm (3) supports the axle (2), the other end of the 
load arm (3) being attached to the chassis (6) by a first

Patent EP-0246694-A3 (EP)
Title: Apparatus for recording and/or reproducing
IPC: G11B15/28
Filed: 1987-05-12
Abstract: A capstan or pressure roller shaft is journalled in a single one-piece elongated bearing member having a bearing surface sufficient to define radial position and inclination of the shaft. The bearing member is aligned with respect to a mounting support on the tape recorder, to adjust shaft alignment, by two axially spaced cylindrical positioning surfaces which are received in axially spaced cylindrical receiving surfaces in the support. At least one of the positioning surfaces is eccentric with respect to the bearing member, and is fixed to the bearing member so that rotation of the bearing member about an axis defined by the receiving surfaces adjusts the inclination of the shaft. The shaft inclination may be adjusted by inserting a tool into the tape recorder, engaging a journal formed in a mounting support adjacent the bearing member, the tool having a gear which engages a toothed portion on the bearing member for rotating the bearing member about the support axis defined by the support receiving surfaces.
Patent EP-0242189-A3 (EP)
Title: Wall feedthrough
IPC: F16L5/02
Filed: 1987-04-14
Abstract: A duct seal for sealing a duct (4) to a substrate (20) such as a feedthrough comprises a sealing member (6), a biasing member (8), such as a wrapped spring sheet and an insert (12) positioned between the substrate (20) and the sealing member (6). The biasing member (8) can be operated, through the insert (12) from the outside of the duct. When the substrate is a feedthrough (20), for example, it is advantageous that the biasing member (8) is operated through the insert rather than through the feedthrough (20) itself, since it allows the feedthrough to be temporarily sealed against contaminants.
Patent EP-0261929-A3 (EP)
IPC: B65B55/08
Filed: 1987-09-22
Abstract: A process is disclosed for packaging a food 
product in a container (1) formed of or lined with a 
heat-resistant thermoplastics. The container is closed 
by sealing to the container a lidding material (12) which is 
permeable to water and gas but impermeable to bacteria, 
such as so-called "medical paper". The food product can 
then be sterilized or pasteurised by heat-treatment and 
the lidding material is then covered by a barrier layer 
which is impermeable to moisture or permits controlled 
moisture permeability. The lidding material and 
barrier material are applied by heat-sealing techniques 
and the final package may be irradiated to sterilize the 
head space between the lidding and barrier layers.

Patent EP-0317963-A3 (EP)
IPC: G11C11/409
Filed: 1988-11-22
Abstract: Data of "0" and "1" are input to input pad (10) 
which is provided for each dRAM chip. The data is input 
to two data input buffers (14a, 14b) via protection cir­
cuit 12. Each of data input buffers (14a, 14b) senses 
the level of input data, converts the sensed level to 
the MOS level and outputs the MOS level data. Data 
input buffers (14a, 14b) are respectively supplied with 
control signals (a, b) for determining the sense-­
timings thereof. The phases of control signals (a, b) 
are shifted from each other. Selection circuit (16) 
selects an output of one of data input buffers (14a, 
14b) in synchronism with control signals (a, b) and 
supply the selected output to a corresponding one of 
write data line (18). Since two data input buffers are 
used, each data input buffer may operate to sense every 
other input data and each of control signals (a, b) is 
set to have a pulse occurring in every two cycles of the 
input data.

Title: Methods and compositions for electroless plating of magnetic recording media
IPC: C23C18/36
Filed: 1988-12-28
Abstract: A plating bath for the electroless coating of 
magnetic recording media substrates includes cobalt, 
nickel, and zinc metal ions in a buffered solution 
including a reducing agent, a strong base, and 
chelating agents. Typically, the reducing agent will include 
phosphorous which will form a portion of the 
ferromagnetic layer being deposited on the substrate. 
By utilizing malic acid or a malate salt as a chelating 
agent, magnetic media having improved signal-to-noise 
ratios, switching field distributions, and corrosion 
resistance, have been obtained.
