Patent EP-0166381-A3 (EP)
IPC: G11B17/04
Filed: 1985-06-20
Abstract: A flexible magnetic disk, rotatably housed in an apertur­
ed envelope to make up a disk cartridge, is loaded through 
an entrance slot in the housing of the apparatus to a preas­
signed position for data transfer with a pair of transducer 
heads on its opposite sides. Upon subsequent manipulation 
of a clamp knob, one of the transducer heads is sprung into 
forced contact with the other transducer heads via the mag­
netic disk therebetween. In order to avoid the direct contact 
of the two transducer heads as a result of the user's tamper­
ing with the clamp knob when the disk cartridge is not load­
ed in the apparatus, a head control mechanism is provided 
for holding the transducer heads away from each other 
when the disk cartridge is not loaded, even if the clamp as­
sembly is then actuated inadvertently. The head control 
mechanism allows the one transducer head to travel toward 
the other for the establishment of data transfer contact with 
the magnetic disk only when the clamp knob is actuated fol­
owing the insertion of the disk cartridge in the entrance 
slot.

IPC: H05K3/12
Filed: 1985-08-28
Abstract: High photo resolution of over 100 lines is obtained for 
solder masks of thicknesses greater than .002 in. (.005 cm) 
with liquid photopolymers of special compositions depo­
sited from mesh screens over printed wiring board traces 
and photoexposed with a phototool image in contact with 
the photopolymer. Special interrelated properties of the 
liquid photopolymer interacting in an explicit process of 
screen depositing two adjacent liquid polymer layers include 
freedom from volatiles a paste-like viscosity permitting use 
with mesh screens of about 60 mesh to obtain a uniform 
thickness layer free of bubbles and mesh marks, solder mask 
insulator and heat resistance characteristics, an ability to 
photo flash through a phototool image in contact with one 
layer surface and the other surface exposed to air to 
polymerize through a significant thickness of about one-third 
of the layer thickness, photo response to polymerize to a 
depth of about .02 in. (.05 cm) when exposed to about 1 joule 
per square cm, absence of ingredients refracting, blocking or 
reflecting the actinic radiation and good adherence to cooper 
wiring. These properties react in the process of bubble-free 
lamination of two paste consistency layers, a first to cover 
uneven wiring traces and a second to provide a flat 
photo-image surface, thereby to achieve thicknesses of 
about .006 in. (.015 cm) for covering wiring traces .004 in. 
(.005 cm) thickness over all wiring traces. This is achieved by 
photo flashing the uppermost layer through a photo image 
with one surface exposed to air to polymerize a surface layer 
that covers the traces permitting the unpolymerized liquid 
paste surface to meet in bubble-free surface contact with an 
initial layer deposited directly over the wiring trace.

Title: Method and system for controlling the electrode erosion of a plasma torch
IPC: H05H1/40
Filed: 1985-11-08
Abstract: Method and device for controlling the erosion of the electrodes of a plasma torch, in which an electrical arc is produced when the electrodes are connected to an electrical supply. An axial magnetic field generated by a system of field coil causes the rotation of the extremities of the arc according to a circular trajectory inside the electrodes. The relative position of the field coils is such that there exists a position on the electrode surface where the value of the total magnetic field is a minimum where the arc runs thereby controlling the erosion of the electrodes. According to the invention, the value of current is periodically varied in the system of field coil used to cause the rotation of the arc, thereby producing a controlled axial displacement of the circular trajectory of the extremity of the arc. The plasma torch according to the invention is characterized by structure to periodically vary the value of the current in the field coil system used to cause the rotation of the arc thereby producing a controlled axial displacement of the circular trajectory of the extremity of the arc. Under these conditions, the life of the electrodes is substantially increased.

Title: Method, system and reagents for dna sequencing
IPC: C12Q1/68
Filed: 1987-07-01
Abstract: A DNA sequencing system and method are described to detect the presence of radiant energy emitted from different excited reporter dye-labeled species (DNA fragments) following separation in time and/or space, and the identity of the species which emit radiant energy closely spaced in wavelength. Functions of the emitted energy are obtained which vary over the wavelengths of the closely spaced spectra in different senses and the functions ratioed, whereby the ratio is indicative of the identity of the DNA fragments. The emitting portion of the reporter-labeled DNA fragment is preferably one of a family of fluorescent dyes based on 9-carboxyethyl-6-hydroxy-3-oxo-3H-xanthene. These xanthene dyes are covalently attached to the DNA fragments through the carboxylic acid functionality, preferably via an amide linkage. The dyes may be protected by including an alkoxy group at the 9-position. A spacer may be inserted between the dye and the amine. The fluorescent dye preferably is attached to the DNA chain terminators and provides many advantages. Thus only DNA sequencing fragments resulting from bona fide termination events will carry a reporter. The DNA sequencing may also be labeled using the xanthene dyes which have general utility as fluorescent labels. Also acyclonucleoside triphosphates are described as being useful as chain terminators in DNA sequencing using a modification of the Sanger method.
