Abstract: A TOY BLOOD PRESSURE MONITORING DEVICE            ABSTRACT OF THE DISCLOSURE           A toy blood pressure monitoring device for simulating the blood pressure monitoring instrument used by doctors.          The device comprises a housing having a diaphragm on one side and a pressure indicating scale on the other side, A fan is mounted for rotation within the housing and has a pointer coupled to the fan and coacting with the scale.  A manually squeezable air impelling bulb is coupled to the housing and adapted when squeezed to substantially simul-taneously direct a pulse of air against the fan and diaphragm.          The air pulse imparts a rotative movement to the pointer over the pressure reading scale to simulate a blood pressure reading.  The pulse of air further deflects the diaphragm which if held against a persons arm simulates the person's heart pulse beat.

Abstract: ABSTRACT OF THE DISCLOSURE A hollow mirror head assembly is disclosed which includes a thin wall mirror supporting shell, an internal bracket member secured between angularly related walls of the mirror head shell to reduce the tendency of said shell to vibrate.  More specifically, the mirror head assembly includes a hollow shall having an open face, a peripheral rim formed about the open face of the shell, and a mirror element mounted in the open face of the shell and retained therein by the rim.  The shell includes a first wall extending rearwardly from the rim, the said wall being generally perpendicular to the mirror element.  The shell includes a second wall projecting from the rearmost end of said first wall and terminates at the peripheral rim.  An opening is formed in the first wall of the shell and a cylindrical support arm extends through this opening.  A bracket structure is mounted within the shell for adjustably supporting the shell upon the support arm.  This bracket structure comprises a first member having a base portion fixed to the first wall of the shell, an elongated planar portion extending normally to said base portion, and means bonding the elongated portion of the first member to the second wall of the shell.  The elongated portion of the first bracket member includes an offset cylindrical section concentrically disposed with respect to the support arm.  This bracket structure includes a second member having a pair of transversely spaced planar portions and an intermediate cylindrical section concentrically disposed with respect to the said support arm.  Means are provided for securing the planar portions of the second member in abutting relationship to the elongated planar portion of the first bracket member in order to clampingly engage the support arm between the cylindrical sections of the first and second bracket members. This makes it possible to rotatably adjust the shell about the support arm.

Abstract: IMPROVED METHOD FOR THE RECOVERY OF METALLIC COPPER                      ABSTRACT         An integrated process for the recovery of copper from impure copper bearing materials is provided by leaching the copper bearing material with sulfuric acid to convert the copper value to the soluble copper sulfate, separating the impure copper sulfate containing solution from the insoluble leach residue, selectively extracting the copper value from the leach liquor by contacting the liquor with an organic extractant for the purpose of obtaining mass transfer between the liquors, separating the organic phase containing the copper value from the aqueous phase of thus reduced copper content, stripping the copper from the organic copper extractant by contacting with liquor of enhanced acid content resulting from a subsequent reduction step, thus regenerating the organic extractant, separating the thus purified copper containing acidified aqueous solution from the solution of the regenerated organic extractant, contacting and thus reacting the acidified copper containing solution with an organic solution of amine extractant to reduce its acid concentration to a desired level, and recovering a part of the copper metal by reacting the copper containing solution of lowered acid content with sulfur dioxide or like reductant before recirculating it, together with any retained copper sulfate and the additionally formed sulfuric acid produced as a result of the reduction step to the step of the process aforesaid in which further copper value is stripped from the loaded organic ion exchange extractant.  Acid value transferred to the amine is largely in the form of an amine sulfate solution in the organic diluent in which the amine is carried but additionally can becarried by adsorption.          This solution is regenerated by contra flow water wash to yield sulfuric acid which is used in the leaching of further ore to produce the feed stream of impure copper sulfate to the extraction stage of the copper ion exchange step of the process.

Abstract: ABSTRACT         Disclosed is an underwater sound projection system for low frequencies. Known systems have used impulsive drives, linear motor drives and electric motors driving a vibrating surface by a crank, cam or hydraulic pump.  These systems tend to be inefficient and to have either narrow bandwidths (e.g. linear motor) or broad bandwidths (impulsive drives).  The system according to the invention is efficient and can be started or stopped abruptly to control bandwidth.  The system comprises a canister closed by a plate at one end and by a piston at the other.          The piston is mounted by a waterproof bellows and can oscillate axially of the canister.  An armature attached to the inner face of the piston is attractable by an electromagnet in the canister.  A holding current through the electromagnet can hold the armature against system compliance; when turned off, the piston begins to oscillate.  A capacitor discharge circuit provides a current pulse to the electromagnet to attract the armature at a time which aids the oscillatory motion of the piston.

Abstract: La divulgation décrit un rehaussement pour petites rallonges d'un trou d'homme. Ce dispositif est destiné à être posé sur l'extrémité supérieure d'un conduit constituant le trou d'homme, la partie supérieure montant comme d'habitude un rebord ainsi qu'une assise située à un niveau inférieur par rapport au rebord. Le rehaussement comprend une première lame horizontale, continue et fermée sur elle-même, de préférence ronde ou carrée, destinée à s'asseoir sur l'assise du conduit. On retrouve aussi une seconde lame, elle aussi horizontale, continue et fermée sur elle-même, de même forme que la première lame, mais dont le périmètre est différent de celui de la première lame, de façon à ce que, dimentionnellement au moins, une des deux lames soit circonscrite par l'autre. La seconde lame est à un niveau supérieur par rapport à la première lame et est destinée à s'asseoir sur le rebord du conduit. Enfin, on décrit des pièces de raccord rattachant les deux lames entre-elles par des faces opposées, de sorte que la deuxième lame occupe le niveau supérieur. Etant donné que ce dispositif est avantageusement construit en acier, il permet d'effectuer de très petites rallonges car, en pratique, la rallonge habituelle en fonte ne peut résister que si l'on a affaire à une rallonge substantielle.

Abstract: ELECTRONIC INVERTER  BALLASTING SYSTEM     ABSTRACT     An electronic ballast employs an electronic inverter which drives a main power transformer across the output of which terminals are connected for a plurality of fluorescent lamps.  A high impedance capacitor is connected in parallel across at least one and less than all of the fluorescent lamps.  An anxiliary transformer is interposed between the output of the main power transformer and the cathode elements of the fluorescent lamps.  Upon start-up, the high impedance capacitor initially creates a bypass around lamps with which it is connected in parallel to thereby apply the entire high voltage output of the power transformer to start the remaining lamps.  Once these lamps are started the voltage drop thereacross is reduced to allow the high voltage output to bypass the high impedance capacitor and start the lamps connected in parallel therewith.          The auxiliary transformer provides good magnetic coupling and low voltage to the cathode elements of the fluorescent lamps.          A separate feedback transformer smaller than the main power transformer operates the electronic inverter to avoid operation of the main power transformer at its saturation limits.
