Abstract: ABSTRACT OF THE DISCLOSURE         An alkali metal acrylate polymer obtained by suspending an aqueous solution of acrylic acid and an alkali metal acrylate in an alicyclic or aliphatic hydrocarbon solvent containing a surfactant having an HLB value of 8-12 and subjecting the suspension to inverse suspension polymerization in the presence of a water-soluble radical polymerization initiator has a much higher water-absorbency and particularly salt solution-absorbency than known ones.  If said polymer is crosslinked with a crosslinking agent, its stability in the fluid-absorbed state for a long period of time is improved and the absorption rate when absorbing water is also improved.

Abstract: JLS:pm   2/7/80 Case 5764 CARRIER ASSEMBLY FOR USE WITH A ROTARY RAILROAD COUPLER SYSTEM      ABSTRACT OF THE DISCLOSURE    To maintain horizontal alignment of a shank and attached coupler head of a rotary railroad coupler system, a middle portion of the shank is supported by a carrier assembly connected to a striker casting of the coupler system.          During rotation of the shank and coupler head in a dumping procedure, for example, the shank interfaces with a saddle casting portion of the carrier assembly to cause wear thereof.          To facilitate replacement of the saddle casting portion once wear becomes excessive, the saddle casting portion is provided with spaced inverted T-shaped lugs which allow the saddle casting portion to be removed from a carrier portion o f the carrier assembly by means of spaced grooves provided in the carrier portion.  Separation of the saddle casting portion from the carrier portion, however, is prevented when the saddle portion and carrier portion are misaligned.

Abstract: ABSTRACT OF THE DISCLOSURE      A universally applicable biopsy needle includes two counter-rotating tubes having oppositely facing sawteeth formed on the distal ends thereof.  A gear system transmits a driving force to the tubes, causing the counter-rotation which permits the sawteeth to act in a sawing manner for penetration of bone samples and in a cutting manner for soft tissues.  Use of an outer cannula allows safe insertion of the needle to the location of the desired sample, and various grasping means are used to extract the sample core.  The concentric, telescoping needles provide a sample preserving the natural architecture and orientation of the tissue or cell types, while minimizing harming and maceration of the same.

Abstract: ABSTRACT OF THE DISCLOSURE       An animal watering apparatus including a thermo insulated tank having a water chamber supplied with water with a water pipe extended to the upper portion of the chamber and a float valve mounted on the pipe to maintain a preselected water level in the chamber.  A top wall mounted on the tank provides a pair of animal drinking openings.  Covers pivoted on the top wall close the open-ings.  A pair of baffles extend downwardly from the inside surface of a top wall.  The baffles are located on opposite sides of the float valve and extend across the water chamber.  Opposite ends of the baffles engage the tank side walls.  The lower edges of the baffles are normally below the surface of the water to isolate the float valve and water pipe outlet from the drinking openings so that cold ambient air does not move across the surface of the water to the vicinity of the float valve to prevent the float valve from freezing in cold weather.  The baffles act as guides for directing convection circulation of the water in the water chamber around the water pipe.

Abstract: ABSTRACT OF THE DISCLOSURE     In a flapper nozzle actuator system a radial outward flow turbine like flapper is used as the flapper.  The angular velocity of the turboflapper is used to lift the turboflapper off a backplate to-wards a nozzle.  The amount of lift off the backplate and hence nozzle outlet area is a function of the angular velocity of the turboflapper.  An adjustable opposing torque of the turboflapper controls the angular velocity of the turboflapper and thus controls the flow rate.

Abstract: ABSTRACT OF THE DISCLOSURE           A method for concentrating ores of non-ferrous metals by flotation, wherein a pulp and air mixture is prepared and fed through a nozzle under pressure to the bottom part of a mixing chamber.  The mixture is directed toward an impact wall in such a manner that after the jet hits against the wall air bubbles of a diameter not exceeding 150-200 µm are formed.  The flows resulting from the impact against this wall are directed toward each other in such a manner as to collide in the top part of the mixing chamber at a velocity maximum 90-100 cm/s and at an angle 40-75° with respect to the vertical axis of the mixing chamber, the resultant flow being dearated, and a re-sultant froth layer removed.  A flotation machine has a mixing chamber having a nozzle for feeding thereto a pulp and air mix-ture and an impact wall disposed directly adjacent to the nozzle, the mixing chamber having walls which are so shaped as to provide for carrying out the abovedescribed method.

Abstract: Abstract The outlets of two independent fixed volume pumps are connected to the two ends of a double-acting, large rod hydraulic cylinder.  The outlets of the two pumps are also connected, through a three-position direction control valve, to tank.  In the neutral position, both outlets are dumped to tank.  In an extension control position, the valve restricts the dump line for one pump, thereby directing its outlet to the cap end of the cylinder; and in the retract control posi-tion the valve restricts the dump line for the other pump, thereby effecting flow to the rod end of the cylinder.  The fluid line between each pump outlet and its respective cylin-der end includes a check valve.  A cross-piloted sequence valve is connected in each fluid line between the respective cylinder end and check valve, and responsive to the pressure of the opposite fluid line.  A control method includes the steps of supplying fluid to the two cylinder ends by respec-tive independent pumps, flowing fluid from the pump outlets to tank and selectively restricting flow to tank from one pump to effect flow from that pulp to the cylinder,and controlling fluid flow from the cylinder by cross-piloted sequence valves.

Abstract: ABSTRACT OPTICAL APPARATUS FOR INTERROGATION OF THE STATUS OF A                      SWITCH Apparatus for interrogating the ON-OFF status of an electrical switch (31) comprises a semiconductor body (4) containing a PN junction and means (5) for electrically connecting an auxiliary switch (32) coupled to the interrogated switch, or alternately the interrogated switch (32) itself, across the PN junction. Light (7) of a first wavelength incident on the semiconductor body causes light of a second wavelength (11) to be emitted from the body when the switch is open (OFF), whereas no such light is emitted from the body when the switch is closed (ON),  Therefore, photoelectric detection of the emission or non-emission of light of the second wavelength from the semiconductor body indicates the status of the switch.

Abstract: ABSTRACT OF THE DISCLOSURE:           The invention concerns the improvement of the fiber distribution in a web or mat, the attenuation of the fibers being effected by means of gas currents.           The material delivered in the form of filaments is attenuated in a channel between two gas jets.  At the outlet of the channel, the gas current carrying the fibers entrains the ambient air and passes through a guide appa-ratus containing two walls.  The circulation of the air induced between the channel and the guide apparatus is modi-fied by the interposition of baffles .           The modification provides for improvement in the uniformity in the fiber web being made.
