Abstract: A portable container includes an outer component defining a hopper-like compartment having a bottom opening and an inner component having a stopper centered in the hopper with respect to the bottom opening and shiftable into and out of stoppering relation to the bottom opening, the outer compartment suspending the inner component into axially slid hopper-stoppering position and there being a target within the lower end of the inner component; and a discharge hopper positioned below the bottom opening and including a lance for penetrating through the bottom opening into contact with the target to axially lift the stopper to unstoppering position in response to lowering of the outer component relative to the discharge hopper. The outer compartment contains a granular product or a mixture of products and the inner component may also contain a compatible product. The dry products of concrete or mortar may thus be stored. The bottom opening of the inner compartment is covered with a diaphragm which is ruptured by the lance prior to engagement of the lance with the target so that the inner compartment is axially shifted relative to the outer compartment so as to effect unstoppering after the diaphragm is penetrated.

Abstract: Ultrasonic sensing systems are incorporated into surgical instruments to monitor operational fields defined by distal ends of the instruments. The instruments include proximal ends for their activation typically including one or a pair of handles which a surgeon grasps and operates, for example by squeezing the handles together or by pivotally moving a trigger portion of the handle relative to a fixed portion of the handle. Circuitry for performing ultrasonic sensing preferably is enclosed in housings defined within the handles of the proximal ends of the instruments. Wiring, preferably running through the instruments, connects the circuitry to transducers formed in or mounted on the distal ends of the surgical instruments. The transducers direct ultrasonic energy to the operational fields defined by the distal ends of the instruments and receive ultrasonic energy reflected from the operational fields. The direction for transmission and receipt of ultrasonic energy is determined by acoustic lenses, angularly oriented transducer mounts or a combination of the two. Signals representative of the tissue or contents of the operational fields of surgical instruments drive audible signal generators or preferably tactile transducers to inform the surgeon of the contents. Tactile transducers are mounted for access by the surgeon, preferably on the handles of the surgical instruments.

Abstract: A pump with a priming circuit containing a valve having a seating with an orifice and an obturator mounted so as to be able to be applied onto the seating in front of the orifice, where the obturator is a resilient blade embedded on one side to the seating. The flexibility of the blade increases from the embedded side to the other. An L-shaped member protrudes from an outer curvilinear wall of a priming element fixed onto the pump. The L-shaped member allows for the seating to be slide into a groove space. The obturator has two holes so that the obturator can be embedded onto the seat by mating with two projections from the seating surface.

Abstract: There is disclosed a method for purifying a used aqueous N-methylmorpholine N-oxide solution reclaimed from a spinning aqueous solution, which results from a coagulation solution into which a cellulose dope containing N-methylmorpholine N-oxide is extruded through a spinning die and from a washing solution for the coagulated cellulosic articles in manufacture processes for cellulose fibers or films, comprising adding an oxidant to the used aqueous N-methylmorpholine N-oxide solution to remove impurities therefrom through oxidizing N-methylmorpholine to N-methylmorpholine N-oxide and break down of the chromophores of the impurities. Utterly distinguished from conventional methods in the principle, the method is very simple and efficient as well as far superior to the conventional methods using ion exchange resin in the decoloration. In addition, it needs not suffer a loss of amine oxide as usual in the ion exchange resin. Further, the oxidant can achieve the decolorization without influence of the concentration of amine oxides. The amine oxide decolorized by the oxidant may be used to prepare the cellulose dope without any more purification. Provided that sequential use of the oxidant and the resin or active carbon, there are brought about much higher efficiency as well as much purer aqueous amine oxide solution.
