Title: Process for the bromination of polystyrenes
IPC: C08F8/20
Filed: 1981-08-19
Abstract: The present process is one for the production of brominated styrene oligomers and polystyrene, preferably what are essentially tribrominated polystyrenes. 
<??>One preferred embodiment of the process can be summarized as consisting of:
 1. dissolving polystyrene having a molecular weight of at least 20,000 in a solvent and
 2. reacting the dissolved polystyrene with a stoichiometric excess of bromine chloride over that required for achieving the desired degree of bromination in the presence of up to about 15% by weight of the polystyrene of a Lewis acid catalyst at about 20 DEG C to about 50 DEG C. 
<??>The dominant substitution pattern in the trihalogenated product is at the 2,4,5 positions, with significantly lesser amounts of other isomers including 2,3,5. There does not appear to be any 2,4,6 substitution. A very small percentage of chlorine is believed to be nuclear bound.

Abstract: The invention contemplates a pipe-bending technique 
wherein an arcuate die which determines the course of 
bending the central axis of the pipe relies solely upon two 
tangentially engaging developing lines of contact which are 
spaced equally, at opposite offsets from the radial plane in 
which the pipe axis is bent. For the case of pipe bending to a 
circular arc, the opposed die faces are generally conical, and 
there is no pipe contact with the die in the range between the 
spaced developing lines of tangential contact.

Title: Prosthetic heart valve
IPC: A61F2/24
Filed: 1985-06-13
Abstract: An improved prosthetic heart valve comprises a support body or stent covered by a layer of biological tissue having only the smooth surfaces thereof presented outwardly. The stent has a cutaway section and a flexible cusp (11) sewn thereto for opening and closing the valve. The valve cusp is made of pericardial tissue which has been doubled over such that the rough side thereof is folded inwardly. A sewing ring (12) is secured around the base of the stent and is made of pericardial or other biological material, so as to increase the likelihood of the sewing ring becoming covered with epithelium. The smooth-surfaced biological construction of the valve is highly durable and reduces the risk of thrombogenic or infection sites.
Patent EP-0152170-A3 (EP)
IPC: D05B33/02
Filed: 1985-01-09
Abstract: A dual-chain sewing machine for aligning the edges and 
the corresponding seam tracks of pieces of a garment that 
have different curvatures and for sewing the pieces together 
along the seam tracks includes two flexible, elongated 
carriers, which move at approximately the same linear speed 
and which are mounted and arranged for motion around 
continuous paths. Each carrier has pins extending from it in a 
direction transverse to the direction of movement, with the 
pins of one carrier extending towards the pins of the other 
carrier. A first fabric piece is applied to the pins of the first 
carrier when a pin bearing portion of the first carrier is in a 
path segment corresponding to the seam track on the first 
fabric piece; a second fabric piece is applied to the pins of the 
second carrier when a pin bearing portion of the second 
carrier is in a path segment corresponding to the seam track 
on the second fabric piece. The second carrier is guided 
towards the first carrier so that the pins of the first carrier 
engage the second fabric piece, and then the second carrier 
is guided away from the first carrier. Consequently, the 
second fabric piece is transferred from the second carrier to 
the first carrier and aligned with the first fabric piece already 
on the pins of the first carrier. The first carrier transports the 
fabric pieces to a sewing machine, which sews them 
together along the desired seam track.

Patent EP-0228027-A3 (EP)
Title: Electromagnetically controlled safe lock
IPC: E05B47/06
Filed: 1986-12-17
Abstract: The latch bolt of a lock is prevented from fully retracting when an electromagnet is unenergized so that a blocking lever carrying the armature can pivot about a pivot point displaced from the armature and a slide or lever pivotally linked to the blocking lever places a blocking nose; when the electromagnet is energized the blocking lever pivots on the armature and thereby moves the slide or lever out of the track of that pin. The armature is normally held against the electromagnet by a spring so that very little electric power is needed and only in case of a desired lock release.
