IPC: A61K6/893
Filed: 1987-01-20
Abstract: Novel compositions, especially light curable com­
positions, are provided which are coherent, but frangible 
when cured. Preferred compositions comprising a major pro­

Patent EP-0276890-A3 (EP)
IPC: A44B18/00
Filed: 1988-01-21
Abstract: In a manufactured article for contact fastener 
constituted by a textile support, from one side of which 
hooking elements protrude, for the purpose of anchoring 
such elements to the textile support, without having to 
resort to a sizing, the same support is formed by warp 
chains (11) tied by at least one weft (13), and the effect yarn (15) 
lengths constituting the hooking elements, which are 
interlaced with the warp chains, are blocked by heat-­
shrunk stitches of said chains. In order to obtain such 
result, the yarns forming the warp chains (11) are constituted 
by a raw material having a coefficient of heat shrinking 
which is considerably larger that that of the weft yarn (13,14) 
tying the warp chains.  
     Also a method and an equipment for accomplishing 
such a textile manufactured article are provided.

Patent EP-0317471-A3 (EP)
Title: Solid state magnetic head with improved biasing
IPC: G11B5/127
Filed: 1988-09-27
Abstract: The magnetic head incorporates a simplified write coil 
structure (9) and an improved and simplified combined 
magnetic bias (11) and sensor current structure (3). The 
active sensing current is utilized both to create an 
anti-parallel magnetic vector couple in a coupled film 
magneto resistive sensor (3) and to magnetically bias or 
torque the anti-parallel couple so that magnetization within 
the sensor films lies at an angle with the easy magnetic 
axis. Sensor current is fed in series through an 
electromagnetic coil (11) wrapped about the magneto 
resistive sensor (3) so that sense current simultaneously 
creates an anti-parallel magnetic vector couple in the 
sensor (3) and generates an electromagnetic bias field to 
torque the anti-parallel couple at an angle with the easy 
axis of magnetization. An improved spirally laid-out planar 
deposited writing flux coil (9) is positioned about the 
writing electromagnetic core (8) which greatly simplifies 
fabrication steps in making the device.

Title: Curved tubular packaging casings, especially sausage casings
IPC: A22C13/00
Filed: 1989-04-10
Abstract: This casing made of unreinforced cellulose has a cross-section with differing wall thicknesses. The section having the minimum wall thickness is opposite the section having maximum wall thickness and is in the section having the larger, outer radius of curvature. The thickness of the section having the maximum wall thickness is in the range of 50 to 160 micrometres, that of the minimum wall thickness is in the range of 10 to 50 micrometres. The maximum of the wall thickness is greater than the minimum of the wall thickness by 50 to 800%. On account of the relationships of its wall thicknesses, the casing shows improved physical properties which are particularly of importance for its use as a synthetic casing for sausages.
