Abstract: Disclosed is a fluid container having a flexible bag containing a diluent and having a closing film at its upper end, a capsule connected to the flexible bag, a drug container held in the capsule and a communicating member for communicating the flexible bag with the drug container. The communicating member has a double-edged hollow needle having a hub in the midway thereof, and a controlling mechanism for controlling the order of communication in such a manner that the plug of the drug container is stuck with one edge of the needle and thereafter the closing film of the flexible bag is stuck with the other end of the needle. The mixing procedure is sure and simple, and can be carried out in a short period of time.

Abstract: An air-fuel mixture heating device for heating an air-fuel mixture supplied from a carburetor to an intake manifold includes an insulator mounted between the carburetor and the intake manifold and having a first air-fuel mixture passage communicating with the primary air-fuel mixture passage in the carburetor, an electric heater disposed in the first air-fuel mixture passage of the insulator for heating the air-fuel mixture, and a plurality of conductors embedded in the insulator and having portions connected to the electric heater and an electric power supply. The insulator has access holes extending to the portions of the conductors for allowing said portions to be joined to the electric heater therethrough. The access holes are filled up with masses of sealing resin after said portions are joined to the electric heater.

Abstract: An improved process for producing benzophenone-azine in which a catalyst can be removed, recovered and recycled is disclosed.

Abstract: A process for continuously preparing benzophenone-azines comprising oxidizing benzophenone-imines with molecular oxygen or a molecular oxygen-containing gas in the presence of a copper halide catalyst is disclosed. The oxidation reaction is carried out in a multistage system under an oxygen partial pressure gradually decreasing from the former stage to the latter stage and at a conversion gradually decreasing from the former stage to the latter stage, while controlling the conversion so that the molar ratio of the benzophenone-imines to the copper halide in the final stage be maintained at 1 or more. By the process, the continuous reaction can stably be performed at a high conversion of the benzophenone-imines without involving insolubilization and sedimentation of the catalyst.

Abstract: A flow control honeycomb structure for use in an intake passage of an engine for producing turbulent flow in an air-fuel mixture flowing through the intake passage, which structure includes a short cylindrical peripheral wall defining therein a circular passage having a substantially circular cross section, a plurality of substantially crisscross partitions joined to and disposed in the peripheral wall and dividing the circular passage into a first group of square passageways each having a substantially square cross section and a second group of four triangular passageways each having a substantially triangular cross section and a relatively large cross-sectional area, and a plurality of ribs extending obliquely from joints of those of the passageways which define the triangular passageways radially outwardly to the peripheral wall through the triangular passageways to divide each of the triangular passageways into a plurality of subpassageways of substantially the same cross-sectional area as the square pass

Abstract: A process for preparing hydrazine hydrohalogenide is disclosed.

Abstract: A stable, storable pharmaceutical composition is provided which comprises a dehydrated solid mixture of microbial cell wall skeleton, vehicle oil, suspending agent and dispersing agent; wherein said microbial cell wall skeleton has adjuvant and antitumor activity. The composition is easily prepared, stable to long term storage, and easily reconstituted to form a homogeneous suspension which retains high potency.

Abstract: An apparatus for securing a typewriter, includes a locking device for locking an outer case in a closed position and a fastening device for fastening a bottom plate of the case to a mounting base. When opened, the cover permits a portion of the bottom plate to be exposed. The fastening device is brought, from inside the case, into engagement with the bottom plate of the case through the exposed portion of the bottom plate, thereby locking the typewriter to the mounting base. The fastening device for the bottom plate cannot be released unless the locking device is unlocked by a key to open the cover. Accordingly, only a keyholder can unlock the locking device, thus preventing the typewriter from being stolen. Further, since the fastening device is engaged with the bottom plate of the typewriter case, the outer appearance of the typewriter is not degraded.

Abstract: A spring support which receives one end of a needle spring to urge the needle in a reset direction is free to move forwards or backwards. During assembly the spring support is disposed in the top end direction of the needle such that the needle is stable at the inserting state of the top end in the needle guide, after completion of the assembly the spring support is moved rearwards and fixed, and the needle is supplied with a restoring force by compression of the needle spring.

Abstract: A process for producing a benzophenone-azine which comprises reacting the corresponding benzophenone-imine with molecular oxygen or benzophenone with ammonia and molecular oxygen in the presence of a catalyst selected from the group consisting of metals, metal oxides and alloys of two or more metals, particularly copper or copper alloy-containing catalyst, is disclosed.

Abstract: Hydrazine sulfate having a relatively large particle diameter and a high purity is produced by hydrolysis of benzophenoneazines by sulfuric acid having a concentration of 75% by weight or less in an amount of 1.1 times by mole or more the stoichiometric amount in a very high conversion and a high yield with less operational loss.

Abstract: This invention relates to an improvement in a wheeled vehicle upon which is mounted a crane or fork lift. More particularly, this invention relates to a wheeled vehicle for conveying loads including a machine bed upon which are mounted three wheel fitting yokes, one rear and two front, to which wheels are respectively attached in the rear center and both front sides of the machine bed as to revolve freely and independently. For steering purposes, an oil pressure power cylinder is connected to each of the wheel fitting yokes through a rack and pinion gear and for locomotion an oil pressure motor furnishes power to the wheels. The wheels may be moved along a circle which passes through the point of ground contact of each wheel, thereby rotating the wheeled vehicle about a circular path centered near the middle of the vehicle. Alternatively, the wheel fitting yokes may be oriented for sidewise motion of the wheeled vehicle.
