Abstract: An apparatus for flanging tubular articles of a thermoplastic polymer which has been drawn and heat-set to an elevated temperature comprises a heating die (20) shaped to receive an end of one of the tubular articles (10) and to restrain it from shrinkage, transfer means such as a star wheel (24) to transfer the article (10) from the heating die (20) to a forming die (22) shaped to form an outward flange (12) on said end. Heater coils (33,40) are provided to maintain the dies at the required temperatures; namely the heating die (20) at a softening temperature above the glass transition temperature of the polymer but below the elevated temperature to which it has been heat-set and the forming die (22) at a forming temperature below the softening temperature. Means, such as a pneumatic system (48,50,52) are provided to apply an end of one of the tubular articles (10) to the heating die (20) so that this end is softened whilst restrained from residual shrinkage by the heating die (20) and also for forcing the forming die (22) and the heat-softened end of the tubular article (10) together to form the outward flange (12). Once the flange (12) has been formed, it is cooled e.g. by cooling air whilst restrained against deformation by the forming die (22) to set the flange in accordance with well-defined dimensions. A method for flanging tubular articles is also disclosed.

Abstract: A pulse oximeter is provided including two light (62, 64) emitting diodes. Each LED is energized by a unique modulation signal. Light produced by the LEDs passes through the tissue of a subject and is detected by a photodiode (60). The photodiode signal is separated by tuned circuits (72, 74) resonant at the two modulation signals frequencies and physiological information signals are recovered from the separated signals by amplitude demodulation (100, 102). The inventive arrangement provides identification of back-to-back coupled LEDs and narrow band filtering for good noise immunity.

Title: Self-supported, adjustable, condensation-free shower mirror.
Inventor: SHOWERTEK INC
IPC: G02B7/18
Filed: 1988-07-22
Abstract: A condensation-free, self-supported shower mirror assembly is heated by water dispersed into a temperature-control space behind the mirror (211). The water is supplied by a supply tube connected from a showerhead pipe (200) to a dispenser which disperses the heated water in either liquid or spray form, preferably from holes in a tube mounted in such temperature-control space. Also the tube acts as a gasket to prevent the heated water from leaking through the front of the mirror (211). The back surface of the mirror (211) is thereby heated to raise the temperature of the front surface of the mirror (211) sufficiently to eliminate water condensation thereon. In one version, mirror adjustment is accomplished through a single flex-joint, such as a hinge of a ball joint which is physically separated from the supply tube. In a preferred version, mirror adjustment is accomplished through a flex-arm (206) which allows rotatable and translational movement. Preferably the supply tube is carried inside the flex-arm (206); the supply tube is mounted by friction fit in the ends of the flex-arm (206). The flex-arm is attached by break-away distal proximal joints so that the parts will not be damaged in case of trauma.

Abstract: A unique dynamic seal assembly is 
used in a mold structure for encapsulat­
ing a glass window assembly with a gas­
ket. The seal assembly resiliently sup­
ports the window assembly (30) and 
cooperates with the mold structure (31) 
for defining a gasket forming cavity (45, 
46). The mould structure typically in­
cludes two cooperating mold sections 
(32, 33) each of which can be provided 
with a groove (37, 43) for receiving a sep­
arate dynamic seal assembly. Each seal 
assembly includes a first sealing body 
(42, 70, 90, 120) having a sealing surface 
which faces and is adapted to sealingly 
contact the window assembly. The first 
seal (47, 48, 73, 92, 122) element is 
formed of a non-deformable, non-com­
pressible material and is connected to a 
second seal element (49, 75, 93, 123) 
formed of a deformable, non-compressi­
ble material which is responsive to pres­
sure applied to the first seal element for 
adjusting the position of the first seal ele­
ment in the mold to accommodate thickness variations in a window assembly contacting the first surface. The first 
seal ele­
ment is typically formed of a Teflon material and is movable in a vertical direction to accommodate thickness 
variations in 
a window assembly contacting the first sealing surface. The second seal element is formed of a silicone rubber 
material or 
is a tube (123) filled with a non-compressible fluid.
