couplings arranged in serial relationship along a single
line.
Subclass: FOR 152
Foreign art collection comprising a fitting having expansible
ends for insertion into and between pipe ends with means
intermediate the ends of the fitting providing a readily
separable coupling. Means for forming a continuous line of
pipe for feeding the pipe through apparatus in a continuous
process (e.g., coating) are here.
Subclass: FOR 153
Foreign art collection including at least two means, each of
which is capable of making a single joint for effecting the
connection and perfecting the seal between the free ends of
two members, e.g., an internally threaded socket having
external threads cooperating with a screw thimble to press a
packing at the lap of the socket and spigot.
Subclass: FOR 154
Foreign art collection wherein one of the means is a molded,
welded or soldered joint.
Subclass: FOR 155
Foreign art collection comprising means to unite tubes made
of diverse materials (e.g., copper to aluminum).
Subclass: FOR 156
Foreign art collection wherein the materials comprise
nonmetal and metal.
Subclass: FOR 157
Foreign art collection wherein the coupling interface of one
of the couplings is different from the coupling interface of
the other.
Subclass: FOR 158
Foreign art collection wherein the couplings provide for a
change in size or a difference in shape of the members to be
joined.
Subclass: FOR 159
Foreign art collection wherein the coupling provides for a
change in size.
Subclass: FOR 160
Foreign art collection wherein the coupling provides for an
off-center relationship which may be adjustable with respect
to the joined members.
Subclass: FOR 161
Foreign art collection wherein a plastic or melted material
is used in the joint or wherein the ends of the members are
united by fusion or by welding pressure.
Subclass: FOR 162
Foreign art collection including means to inhibit or repeal
the growth of roots between the members.
Subclass: FOR 163
Foreign art collection wherein the pipes are united by a
weld.
Subclass: FOR 164
Foreign art collection wherein the members are bonded by
soldering.
Subclass: FOR 165
Foreign art collection in which at least the ends of the
members to be joined are of composite material, such as
cement, asphalt, concrete, or glass combined with other
materials reinforcement.
Subclass: FOR 166
Foreign art collection in which the ends of the members are
additionally held together by means of threads.
Subclass: FOR 167
Foreign art collection in which the members are also
connected by a lug and slot means, e.g., a bayonet joint.
Subclass: FOR 168
Foreign art collection wherein a member is molded to the end
of a pipe.
Subclass: FOR 169
Foreign art collection which include a short sleeve or tube.
Subclass: FOR 170
Foreign art collection in which the sleeve is a wrapping or
taping material.
Subclass: FOR 171
Foreign art collection in which the sleeve has an aperture,
or spruce, for pouring the molding material.
Subclass: FOR 172
Foreign art collection in which filler material in addition
to the molding or caulking material is utilized to save on
the amount of molding material used, etc.
Subclass: FOR 173
Foreign art collection in which filler is in the form of
rings having wedging surfaces.
Subclass: FOR 174
Foreign art collection having an aperture or sprue for
pouring the molding material into the joint.
