Title: Semi-aromatic copolyamides and copolyester-amides and process for preparing them
IPC: C08G69/36
Filed: 1989-11-29
Abstract: Semi-aromatic copolyamides and copolyester-amides are obtained by placing an aliphatic polyamide into contact with an aromatic hydroxyacid or aminoacid, by operating at high temperature, under melting conditions, possibly in the presence of a catalyst, with a ratio of the monomer units of aliphatic polyamide to the mols of aromatic hydroxyacid or aminoacid comprised within the range of from 20:1 to 1:1. The semiaromatic copolyamides and copolyester-amides so obtained can display a thermotropic liquid-crystal behaviour as a function of their content of aromatic units linked inside the molecular chain. Their elastic modulus results to be improved relatively to the alifatic polyamides used as the starting product, and the elongation at break results to be decreased. Such semiaromatic polyamides and copolyester-amides can find application in the production of high-stiffness articles, by means of moulding or extrusion processes. They can also be used as blends with the usual thermoplastic polymers, in which they act as reinforcer or compatibilizer agents.
Patent EP-0327256-A3 (EP)
IPC: B29C65/74
Filed: 1989-01-26
Abstract: A method of welding at least two layers (18, 20) of 
thermoplastic material, e.g. polyethylene terephthalate 
or polyporopylene, and a weld (30) so produced comprises 
directing a jet of hot gas from a nozzle (10), through a 
hole (16) in an inlet mask (16), and against the layers 
(18, 20). The layers (18, 20) are backed by an outlet 
mask (22) having a hole (26) and serving as a heat sink. 
The inlet mask (16), the layers (18, 20), and the outlet 
mask (22) are clamped together. A transverse weld (30) 
is formed entirely of the material of the layers (18, 
20). The weld (30) has a columnar shape with an enlarged 
end (32′), which is cold-headed. The opposite end of the 
weld is level with or depressed with respect to marginal 
surfaces of the adjacent layer (18, 20). If the material 
is crystallizable, the weld may be more crystalline than 
other portions of the layers.

Title: Precision medium handling system and method and devices therefor
IPC: B65H23/02
Filed: 1990-02-07
Abstract: Accurate control of the lateral position 
and spacing of a photosensitive medium (2) is provided 
for recording a succession of lines representing 
graphic images or portions thereof, without mechanical 
edge guides. The apparatus includes an optical 
edge detector (14), a film drive assembly having two 
independently controlled feed units (10; 12), and a deviation 
correction means to correct the position prior to 
actual printing of images. Preferably, a triang­
ulation method is used to electronically correct

is obtained by the combined action of the two independent 
feed units (10; 12) operated by an electronic control circuit 
receiving signals generated by the optical edge 
detector. The apparatus also includes means (35-37) to 
maintain the image receiving section of the photo­
sensitive medium (2) in a flat plane. An image placement 
carriage (200) carrying optical elements (202) is supported 
on magnetic slider pads (211-213) forming bearing elements 
which hold the carriage onto smooth tracks (208) made 
of magnetic material, thus minimizing or eleminating
