Abstract: ABSTRACT                A method and apparatus are described for automatically placing a modem in the answer or originate mode of operation without the use of a ring detector or a manually operated answer/originate mode selection switch. A timer and two latches are connected in the modem in such a fashion that when the modem is switched into operation it is in the originate mode.  For a period of time determined by the timer, the modem looks for the receipt of an answer tone from a remotely located modem.  If the answer tone is detected within this time, the modem remains in the originate mode and completes a handshaking sequence with the remote modem.  If, however, the answer tone is not received, the modem automatically switches to the answer mode of operation and transmits an answer tone as part of the handshaking sequence.

Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to an improved method of installing an elongated heater such as a cartridge heater in a molding member such as an injection molding manifold member.  First, a bore is drilled into an elongated portion of the manifold member to extend generally parallel to the hot runner passage extending through it and a filler duct is drilled from the top to intersect the bore along its length.  The cartridge heater is then inserted into the bore and a filler tube with a base is set on the top in alignment with the filler duct.          A brazing paste is then applied around the base of the filler tube and around the terminal portions of the cartridge heater extending from the bore.  The manifold member is then heated in a vacuum furnace which brazes the filler tube in position and seals the outer end of the duct against leakage.  A slug of copper is then inserted into the filler tube and the manifold member is again heated in the vacuum furnace sufficiently to cast the conductive copper to fill the space around the cartridge heater.  The filler tube is then machined off to produce the finished manifold member.  The copper fuses to the outer casing of the cartridge heater and the bore and together with the elimination of the insulative air space around the cartridge heater substantially improves heat flow and reduces the formation of hot spots which cause the heating element to burn out.  In another embodiment, a tubular heater having two terminal portions is installed in a heater plate of a thermosetting mold with the terminal portions extending at opposite ends of the heater plate.

Abstract: ABSTRACT OF THE DISCLOSURE:         A self-storing, inflatable pool cover designed to float to the surface of the pool when inflated and form over this surface an insulating air dome, and to sink to, and spread over, the bottom of the pool when deflated.  This pool cover comprises a plastic membrane shaped to substantially conform with the inner periphery of the pool and ringed by an endless, peripherical tube provided at one side with at least one bleed hole opening onto the bottom of the membrane, and with an air intake at the other side opposite to the one side.  An inflatable bladder is fixed slightly off center onto the membrane.  A closable air-vent is connected to the membrane near the bladder, and an air-line connnectable to a compressed air supply is provided to supply air to the spout of the bladder and to the intake of the tube in this order.  In use, connection of the air line to the air supply while the air vent is closed causes the bladder to inflate and to raise the center of the membrane in such a manner that this membrane may trap the air subsequently forced by the air supply through the endless tube and the bleed hole.  This raises upwardly from the bottom of the pool until it floats to the surface of the same.  In contrast, opening of the air vent while the air line is disconnected from the air supply, causes the trapped air to escape, the bladder to deflate and the cover to sink to the bottom of the pool.

Abstract: ABSTRACT OF THE DISCLOSURE              AN INJECTION WATER VISCOSIFIER   FOR ENHANCED OIL RECOVERY    High molecular weight N,N-dimethylacrylamide copolymers and terpolymers were synthesized.  These poly-mers offer outstanding advantages as injection water viscosifiers in enhanced oil recovery processes including chemical, miscible, and steam or in processes requiring profile improvement through adsorption and/or gelation. They are very valuable in applications where high salinity is a problem since they are relatively insens-itive to metal salts (such as those containing polyvalent ions, such as Ca++ and Mg++).
