Abstract: An agglomerated powdery milk product is prepared by spraying a concentrate of milk or a fraction thereof into a stream of drying gas directed against the surface of a fluidized layer of already spray dried particles in a conical chamber, thereby obtaining a favorable interaction. Special parameters including temperatures, rates of streams of drying air and residence time are adjusted to obtain an extensively agglomerated product, high production capacity, improved heat economy, low heat damage of the product, and to make possible an easy spray drying of materials, which have hitherto been regarded as unsuitable for spray drying.

Abstract: Amidino compounds represented by the formula (I) ##STR1## and pharmaceutically acceptable acid addition salts thereof are novel compounds and are useful as powerful antitrypsine, antiplasmin, antikallikrein and anti-thrombin agents. Having strong anti-Cl (Clr, Cls) activities and an anticomplement activity, they are also useful as anticomplement agents. These amidino compounds are prepared by usual esterification of carboxylic acid compounds represented by the formula (II)R.sub.1 --COOH (II)with 4-(.beta.-amidinoethenyl)phenol represented by the formula (III) ##STR2## and, if necessary, can be transformed into pharmaceutically acceptable acid addition salts thereof.

Abstract: The invention relates to an electromagnetic induction coil or antenna device embedded in hearing aids or radio sets for receiving sound signals or carrier signals generated by a primary electromagnetic induction coil which is laid down in the room. A plurality of coils each one end of which is commonly connected and each other end of which extends outwardly from the one end so as to be uniformly arranged in a space and a phase selector connected to the coils operates, as a mercury switch, to pick up positive phase component output signals which are induced in at least any of the coils. The coils and the phase selector are fixedly built in the body of a hearing aid, etc. so that the corresponding coil and conduit in which a suitable quantity of mercury is charged may be paralleled to each other and so on, thereby to obtain a constant output sound pressure irrespective of the posture of a person wearing a hearing aid or enjoying television.

Abstract: A plastic closure having pilfer-proofing characteristics for a container including a mouth-neck portion having formed on its peripheral surface an external thread and an annular flange located beneath it. The closure includes a top panel wall and a cylindrical skirt wall extending downwardly from the peripheral edge of the top panel wall. A breakable line extending circumferentially is formed on the skirt wall to divide the skirt wall into a main portion above the breakable line and a pilfer-proof bottom portion below it, and an internal thread adapted to be fitted with the external thread of the mouth-neck portion of the container is formed on the inner surface of the main portion of the skirt wall. The inner surface of the pilfer-proof bottom portion has formed therein at least one flap extending radially inwardly therefrom.

Abstract: The hoppers (2) containing the powder products have a parallelepiped shape and are mounted side by side so that they can be moved by sliding on a slideway support (3). They are maintained in position by locking tabs (6). A plate forming a pan (38) is also mounted so as to be moved by sliding on horizontal slideways. The filling, and also the servicing and cleaning of the machine are thus made much easier.

Abstract: An apparatus for cutting out the vent of a bird being made ready for consumption substantially comprises a number of rotatingly driven hollow cylindrical knives which each are secured to a slide. Each slide is provided with a roller which engages a curved cam surface of the apparatus. A corresponding number of positioning means are also provided with a roller which engages another curved cam surface. The problems relating to different dimensions of the birds and their legs are overcome by a structure which enables the rollers to depart from the paths determined by the curved cam surfaces.

Said elements are realized in the form of plinths, beams, rooms, staircases, roofs, floors and panels provided with a base by means of which said panel result to be independent for what concerns the stability, all of said elements being provided with a particular shape and with particular means so as to allow the assembling for the construction of a building of one or more floors, whereby the stability of said building is guaranteed, according to the different cases, by the own weight of the elements and/or by reinforcing means realized during the assembly.

Abstract: An emission-electron microscope comprises an evacuated chamber with a superconducting magnet at one end generating a region of very high field strength. In this region a specimen is mounted and the surface of the specimen is irradiated with photons, typically x-ray or hard ultra-violet, from a source. As a result the specimen emits photo-electrons. The magnetic field is axially symmetrical along the length of the chamber and emitted electrons spiral about the lines of force traveling down the chamber into a region of lower magnetic field controlled by electro-magnet coils. Transverse kinetic energy of the electrons is converted into energy along the lines of force of the magnetic field and the divergence of the magnetic field lines causes electrons to produce on a detector an expanded electron image indicative of the distribution of electron flux across the surface region of the specimen.

Abstract: A gel-forming protein product is prepared from a raw material of either defatted or non-defatted oil seeds or products derived therefrom, which contain proteins, carbohydrates and a polysaccharide fraction. The proteins are subjected to a thermal treatment in water. The thermal treatment comprises heating the proteins in one or more stages at a temperature above 50.degree. C. The proteins need not be separated from other constituents of the raw materials but are separated from the polysaccharide fraction. The protein product can be formed into gels having desirable compressibility and elasticity characteristics. The gels are useful in foodstuffs.

Abstract: In a coin disposing apparatus, a mechanism is disclosed for aligning a random supply of coins preparatory to further processing. Included is a rotary disc for receiving thereon the coins to be processed from an overhead belt conveyor and for centrifugally sending the coins toward the disc periphery. A coin runway extends from a peripheral position on the rotary disc to a subsequent processing station for aligned delivery of the coins. An endless belt makes frictional contact with the periphery of the rotary disc, except at least where the entrance of the coin runway is located, for simultaneous rotation therewith. Thus, on being centrifugally forced into peripheral contact with the endless belt on the rotary disc, the coins do not revolve about their own axes, unlike the case where the disc rotates inside a fixed annular wall, and so is smoothly and noiselessly fed into the runway one by one. The invention also features a fixed annular wall arranged over the endless belt rotary wall.
