Abstract: Fine metallic nitride powders having a high purity are prepared, without causing any plugging or other problems in the reaction apparatus and with easy heat control of the reaction, by reacting a metallic halide with liquid ammonia in the presence of an organic solvent which has a specific gravity higher than that of liquid ammonia, and also is not miscible or is only slightly miscible with liquid ammonia at a reaction temperature. The process according to the present invention is effected by introducing the metallic halide into the lower organic solvent layer of the reaction system.

Abstract: A calling party's telephone number displaying device in which, while the telephone set of a subscriber is ringing in response to calling signals from a telephone exchange office, the telephone number of a calling party and information are displayed on digital display units at high speed before lifting the handset. Accordingly, the subscriber can determine whether or not he should answer the call before picking up the handset. Thus, his privacy can be protected from a variety of telephone troubles such as wrong number and nuisance calls. The display is maintained as it is even if the handset is put back after the talk but it will be cleared automatically upon reception of the next call to display the telephone number of the next calling party. When the subscriber picks up the handset to make a call, the internal circuit is automatically changed to display a telephone number dialed by him.

Data records assembled in the data buffer memory are transferred to the magnetic storage devices to provide a semi-permanent record file which is transferrable to a host processing unit.

Abstract: The use of thioamido and alkynyl substituted heterocyclic ammonium salts in producing images in silver halide photographic elements is disclosed. The thioamido and alkynyl substituted heterocyclic ammonium salts can be incorporated in photographic silver halide emulsions. The thioamido substituent is capable of promoting adsorption of these salts to silver halide grain surfaces. In negative working surface latent image forming emulsions the thioamido and alkynyl substituted heterocyclic ammonium salts permit higher speeds to be achieved. In direct positive internal latent image forming emulsions nucleation activity and improved incubation stability can be achieved.

Abstract: Dispensing apparatus for dispensing bleach and/or detergent or the like into a toilet tank on a controlled basis. The dispenser is rotatable or tiltable; being divided into several portions, one of which is a reservoir, preferably provided at the top of the structure, such reservoir determining the controlled "shot" or dosage to be dispensed. In operation, the dispenser is buoyed up by incoming water such that it rotates, and the reservoir becomes partly filled; but water cannot enter, to any significant extent, from the reservoir into the main chamber of the dispenser. When the water level drops sufficiently in the tank, the device then rotates to an upright position, the trapped air no longer contributing to the buoyancy of the device. Also, the water present in the reservoir can now enter the container and cause the cleaning solution, formed from a cake of bleach or blue dye/detergent, to overflow and be dispensed into the toilet tank and thence to the toilet bowl.

The elongate second gear is mounted about its periphery by a plurality of spring members, the spring members being employed to introduce play into the apparatus to facilitate the orbiting of the second gear by the first gear.

Abstract: A helical brush section consisting of a split tubular support or drum. The drum is offset at the split when the brush strip is helically wound thereon with its ends corresponding to the shoulders at the ends of the offset drum. Then the section is subjected to axial pressure to restore the drum to cylindrical form which distorts and flattens the ends of the brush strip inwardly substantially flush with the drum ends. Multiples of this resulting section are adapted to be disposed on a mandrel with their adjacent edges and shoulders in axially-abutting relationship to form a continuous helical rotary brush with a minimum of bristle gaps at the flattened ends of the brush strips.

Abstract: A windshield wiper assembly providing improved wiping characteristics. The wiper assembly includes a wiper arm, a superstructure, and a flexible wiper insert received within the superstructure. The wiper insert includes a flexible elongate beam received within the superstructure at both ends and which serves to uniformly distribute the force transmitted by the superstructure from the wiper arm along the length of a flexible wiper strip which forms a part for the wiper insert. In its unflexed configuration, the elongate beam is characterized by a first surface which is elliptically curved convexly along the length of the beam and a second oppositely disposed surface which is flat. When the elliptically curved surface is flexed due to the application of a force from the superstructure at each end of the beam the force is equally distributed along the length of the beam.

Abstract: First (12) and second (42,62) body portions are each attached to a structural member. The first body portion (12) includes trunnions (18) that are slidably received in corresponding channels in the second body portion (42,62). The second body portion (42,62) includes a base member (62) and a pivot member (42), which cooperate to form the channels. The pivot member (42) has an open position and a closed position. A spring (82) biases the pivot member (42) in its closed position. A lever (44) moves the pivot member (42) against the force of the spring (82) into its open position. When the pivot member (42) is in its closed position, it blocks portions of the channels, thereby locking the trunnions (18) into one of two lock positions in the channels. When the pivot member (42) is in its open position, the trunnions (18) may slide in the channels from one lock position to another or out of the channels to disengage the two body portions.

Abstract: An adjustable friction hinge assembly of thermoplastic material comprises a first hinge leaf having spaced apart non-adjustable knuckles having non-circular through holes, and a second hinge leaf having a single knuckle which fits into the space between the spaced-apart non-adjustable knuckles.

When the binder is provisionally attached to the panel, the pendant portion causes the buckle to rise amply from the panel surface and facilitates the insertion of the band into the buckle.

Abstract: A cable tie comprises a strap having a series of transverse teeth on one side extending between the longitudinal edges thereof, and a fastening head having a passageway therethrough for receiving the strap to form a loop. The fastening head has a pawl cooperable with the strap teeth. The longitudinal edges of the strap are at least in part transversely oblique and each of the corresponding lateral walls of the passageway are similarly transversely oblique. The transversely oblique edge portions on the strap converge to the side of the strap away from the side having the teeth so that the pawl produces a wedging effect to clamp the strap transversely between the lateral wall portions of the passageway. Also, the lateral wall portions of the passageway converge toward each other in a direction away from the pawl. The oblique portions are preferably surface roughened.

Abstract: The present invention relates to a method for producing a cleansing and wiping cloth, particularly a cloth of low density wefts and warps formed by interwoven 100% count No. 20 rayon yarn which is treated by chemicals. The treatment includes starching the yarn with cassava starch and CMC having the property of suspending contaminant particles, softening the yarn by a mixture of hydrogen peroxide and a softening agent. The fillers may completely fill up the non-crystalline space of the fibers and cling to the surface of the cloth. The cloth is, in turn, pulled by rollers and ironed, and scissored into pieces of proper size. At least six such pieces are stacked together and hemmed around the periphery to form an entity. The structure is further reinforced by stitching, thereby forming a cleansing and wiping cloth which exhibits excellent absorptivity to moisture, which is easy to dry, and which does not retain any contaminant or unpleasant smell.
