Patent EP-0308815-A3 (EP)
Title: Medical instrument valve
IPC: A61M25/00
Filed: 1988-09-15
Abstract: A hemostasis valve is provided for catheters or the 
like, comprising an elastomeric partition valve secured in a 
housing. A linear slit extends through the partition valve 
between the major faces thereof. By this invention, the 
partition of the valve has at least one concave face through 
which the slit extends. Such a partition valve provides 
further improved sealing characteristics over a wide range of 
diameters of catheters, leads, or the like penetrating the 
partition valve, particularly reducing frictional resistance 
to catheter advancement and rotation through the valve and 
also reducing catheter collapse in the valve.

Abstract: In the production of a waveguide, a pipe (1) of a glass 
which is soluble in an acid or an alkali is used in order to 
obtain a smooth inner peripheral surface of a reflecting layer 
(2, 2C) of the waveguide. After the reflecting layer is 
formed on the outer periphery of the pipe, the glass pipe is 
dipped in an etchant to be dissolved and removed. A 
reinforcement layer (3) can be applied to the waveguide, and the 
reinforcement layer is made of a resin in order to keep the 
flexibility of the waveguide. In this case, the reinforcement 
layer of a resin is formed on the outer periphery of the 
reflecting layer (2) on the pipe (1), and thereafter the pipe is 
dipped in the etchant and is removed. The waveguide of a 
circular cross-section can be flatted. In this case, the 
reinforcement layer (3) made of a thermoplastic resin is 
heated to be softened, and then a compressive force is applied 
to the waveguide radially thereof to flatten the waveguide.

Title: Quick-release electrical connector coupling device
IPC: H01R13/627
Filed: 1989-11-13
Abstract: An electrical coupling assembly has a receptacle portion (10) 
attached to an electrical connector element (14) and releasably 
attached to a housing (34), affixed to the opposite electrical 
connector portion (28), by engagement of a latching ball (36) on 
the housing (34) with a latching detent (20) on the receptacle 
(10). Axial movement of an operating sleeve (44), with respect to 
the housing (34) facilitates the coupling and decoupling of the 
housing (34) and the receptacle (10). The operating sleeve (44) is 
spring (56) biased to assume a position with respect to the housing 
(34) retaining the coupling portions together. A force exerted on a 
lanyard (62) attached to the sleeve (44) axially moves the sleeve 
with respect to the housing (34) to decouple the coupling elements. 
A lanyard guide ring (64) is attached to the housing (34) and has 
an opening through which the lanyard (62) passes such that the 
portion of the lanyard (62) extending between the guide ring (64) 
and the operating sleeve (44) extends in a generally axial 
direction, as well as the direction of force exerted on the sleeve 
(44) by the lanyard (62). The coupling includes a mechanism (38) 
for disengaging the electrical connector portions before allowing 
the coupling elements to separate.

Abstract: A thin film bonding method and apparatus having 
structure for removing wetting agents applied to a 
thin film and base plate that are to be bonded by 
pressure and heat. A spray or rollers (30) apply the 
wetting agent prior to the initial bonding of a 
leading edge of the thin film to a leading edge of the 
base plate. A pressure roller (15) applies heat and 
pressure to the film and base plate, bonding them 
together as the roller rotates and drives the plate 
toward a cleaning position. Suction and agent removal 
rollers (80) are used to remove the residual excess agent 
from the bonded film and the pressure roller. The 
removal rollers are joined together by a link 
mechanism that has a spring bias and is operation by 
a gear mechanism that provides a wiping action.

Abstract: A process for removing sulfur dioxide from a flue gas in a wet scrubber with an aqueous slurry formed from calcium hydroxide and magnesium hydroxide with magnesium hydroxide or magnesium oxide recovered therefrom. A thickened sludge from a thickener containing calcium sulfite solids is separated and an aqueous sulfite solution removed, with a first portion of the solution returned to the thickener while a second portion thereof is oxidized to form a sulfate solution. Lime is added to the sulfate solution to precipitate calcium sulfate and form an aqueous magnesium hydroxide suspension, with the precipitated calcium sulfate separated from the magnesium hydroxide suspension which may be dewatered to form a magnesium hydroxide product or calcined to produce magnesium oxide. <IMAGE>

Title: Apparatus for controlling rotational speed by optical data collection
IPC: G01D5/30
Filed: 1986-12-03
Abstract: The apparatus is particularly suitable for controlling 
rotational speed of an inner housing (26) relative to an outer 
housing (12) in a centrifuge in which both housings rotate about 
a common axis. A reflector (58) is provided on the inner 
housing offset from the axis and an optic fibre (52) extends 
through the outer housing along the axis and terminates in the 
outer housing at a position offset from the axis to transmit 
radiation from a source (42) to impinge on the reflector. 
Reflected radiation is transmitted back down the optic fibre and 
is sensed by a sensor (66) as an indication of rotational 
velocity of the inner housing. A second sensor (74) senses the 
rotational speed of the outer housing (12) and a control system 
(70) compares the outposts of the sensors and controls the 
relative rotational velocities of the housings.

Title: Impact resistant polyblends of polyamides, anhydride copolymers and functionalized elastomers
IPC: C08L35/06
Filed: 1990-01-04
Abstract: Moldable multi-phase polyblends having excellent impact 
properties are disclosed which comprise blends of a polyamide, a 
thermoplastic copolymer of an α,β-unsaturated carboxylic acid 
anhydride and a monovinyl aromatic monomer, and an anhydride-­
functionalized elastomer. The functionalized elastomers are low 
in unsaturation, providing polyblends having good oxidative 
stability, and are comprised of α,β-carboxylic acid anhydride 
adducts of either EPDM-type rubbers, hydrogenated block or random 
copolymers of monovinyl aromatic monomers and conjugated dienes, 
or hydrogenated polymers of conjugated dienes. Compatibilization 
of the blends is believed to be accomplished by chemical grafting 
of the polyamide onto the thermoplastic copolymer and the 
functionalized elastomer.
