Abstract: AQUEOUS EPOXY-PHENOLIC COATINGS                       ABSTRACT     Aqueous thermosetting coating compositions adapted for roll coat application are disclosed in which water has dispersed therein an adduct of a diglycidyl ether of a bisphenol having a 1,2-epoxy equivalency of at least 1.2 and an average molecular weight of from about 2000 to about 5000 with a stoichiometric proportion, based on epoxy and secondary amine, of diprimary amine having a single secondary amine group and each primary amine group blocked by a ketimine group.  At least about 50% of the amine groups of this adduct are protonated with a volatile acid, and the ketimine groups hydrolyze in the water to provide primary amine functionality and ketone solvent in the aqueous medium.  From 20% to 50%, based on total resin solids, of water insoluble, heat-hardening phenol-formaldehyde resin curing agent is employed for cure.  The curing agents are added to the adduct in solution in water-miscible organic solvent, and cresol-formaldehyde curing agents are preferred.

Abstract: ABSTRACT OF THE DISCLOSURE       A hair curling roller system having a plurality of post members have substantially the same outer diameter for heating the rollers and a plurality of rollers having inner cavities for mounting the rollers on the posts with such inner cavities having substantially the same inner diameters.   There are at least two groups of the rollers, with the outer diameter of the rollers of one group being larger than the outer diameter of the rollers of the other group.          Each of the curling rollers includes an interior core member having an opening in one lateral end of the core member and longitudinally extending within the core member; this core member is formed of a material highly conductive of heat.  In each of the larger rollers the interior core has a central hub and a plurality of heat radiating fins extending out from the hub for facilitating the transfer of heat to the outer surface of the roller.  A hollow sleeve member with a flocked outer surface is arranged over the core member.  A first end ring is attached to the core member at one lateral end thereof; this first end ring has a flange extending over but spaced from the adjacent end portion of the flocked outer surface of the sleeve member.  A second end ring having an attachment member is connected to the core member at the other lateral end thereof by the attachment; the second end ring has a flange extending over but spaced from the adjacent end portion of the flocked outer surface of the sleeve member.  The first and second end rings are formed of a low heat conducting material.  The attachment member has a prong mounted on an inner surface of the second end ring facing the core member.  The prong is inserted into the opening in the core member for securing the second end ring to the core member.

Abstract: ABSTRACT      Cesium is recovered from cesium alum, CsAl(SO4)2, by a two-reaction sequence in which the cesium alum is first dissolved in an aqueous hydroxide solution to form cesium alum hydroxide, CsAl(OH)3, and potassium sulfate, K2SO4. Part of the K2SO4 precipitates and is separated from the supernatant solution.  In the second reaction, a water-soluble permanganate, such as potassium permanganate, KMnO4, is added to the supernatant.  This reaction forms a precipitate of cesium permanganate, CsMnO4.  This precipitate may be separated from the residual solution to obtain cesium permanganate of high purity, which can be sold as a product or converted into other cesium compounds.

Abstract: ABSTRACT:   Four fingers of a hand of an individual person, i.e. the index finger, the middle finger, the medical finger and the little finger are placed on a transparent measuring table in juxtaposition.  A guide member is also placed on the table to restrict the position of the hand and light is irradiated onto the table.  The intensity of the light passed through the transparent measuring table is scanned by a television camera and so on at every light receiving point to convert it an electrical signal.          Thus obtained electric signals are processed to calcurate the differential data of the finger lengths thereby detecting an individual person.

Abstract: The invention solves the problem of self-acting increase of internal friction of the differential gear after exceeding the limit value of the ratio of rotational speeds of driven axle shafts of the vehicle. The increase of internal friction brings about the increase of driving force in ground driving, whereas its dependence on the ratio of rotational speeds of axle shafts causes that the friction is of short duration and occurs only at moments when one of wheels begins to skid. the gear comprises a friction clutch consisting of an external hub /1/ connected with the housing of the differential gear /2/, an internal hub /3/ mounted rotatably in the said housing, and compressed friction disks /4, 5/. On the driven axle shaft /7/ a polygonal sleeve /8/ is mounted non-rotatably, between the walls of which and the cylindrical surface of the internal hub /3/ rollers /9/ are placed with radial clearance, which are held by a cage /10/ provided with a friction flange pressed down to the external hub /1/ coupled with the housing of the differential gear /2/ by disk springs /14/ through the intermediary of the pressure disk /13/. The pressure disk /13/ contacts with ends of followers /15/, the opposite ends of which abut on the frontal cam /16/ fixed non-rotatably in relation to the housing of the driving axle. he cage /10/ is mounted rotatably on the cylindrical part of the polygonal sleeve /8/, in which radial blind holes are made and therein, springs /11/ and balls /12/ are placed abutting on-the roof shaped recesses in the cage /10/. The invention is intended for driving axles of vehicles. Its use is advisable especially in ground motor-cars and lorries, vehicles used in agriculture and forestry and self-propelled machines.

Abstract: ABSTRACT OF THE DISCLOSURE          In a flat cable energy distribution system in which the conductors of the cable are connected to a device in a box, the box is grounded to the ground conductor of the cable by a point extending from the metal base of the box.  An insulating bar with a through-hole through which the point extends re-ceives the cable between pairs of projections and an elastic metal strip overlies the cable and is disposed between pairs of such projections.  The strip and the bar are secured at their ends to the base by screws which pass through the bar and the strip and which engage the base.  When they are so secured, the point pierces the insulation of the ground conductor and engages the conductor, and the strip is elastically deformed causing it to apply pressure to the conductor and thereby causing the latter to press against the point.

Abstract: ABSTRACT         The suppression of the reverse injection of the carriers in a bipolar transistor, without adversely effecting forward injection, is carried out by modifying the energy gap characteristics of the transistor so that a greater barrier to reverse injection is presented than that which is confronted by the forward injected carriers.  The energy gap of the emitter is increased, relative to that of the base, through ion implanta-tion.  The ions which are implanted are such that the resulting compound material has a higher energy gap than that of silicon into which they are implanted to selectively modify the emitter region so as to locally increase its energy gap. Preferred materials include carbon and nitrogen.

Abstract: ABSTRACT OF THE DISCLOSURE         Mini-pellets made of raw material derives from fine powder iron ores are indurated, and possess the property of diffusion bonding.  A plurality of these treated mini-pellets are combined with calcium ferrites at the surface layers thereof. This produces agglomerated ores in which the main grain size of the fine powder iron ores are not more than 5 mm.  The agglomerated  ores  are  subjected  to  a  primary pelletization with a flux, and solid fuels are coated thereon  in  a  secondary  pelletization to  produce mini-pellets of 3 to 9 mm diameter.  The mini-pellets obtained are subjected to induration in a travelling grate sintering furnace.  The agglomerated ores and the method according to the present invention, enable to select  the raw materials from a wide range of grain sizes. The blow capacity may only be small, the yield of agglomerated ores may be increased,  and the resulting products have improved properties because of high RI and low RDI.
