Abstract: A cylindrical tool with a breaking edge at one end, when disposed over and about an end of an egg, upon being struck, penetrates the shell to sever an end segment therefrom. The breaking edge is at the end of a thin member having a wall thickness of the same order of magnitude as the thickness of the egg shell, a double beveled end, and a reinforced body. The tool may be separately contained with its own handle or may be integrated in a separable base of an egg cup. The egg cup bowl may be elastic or otherwise provided with means for cushioning the egg. The breaking edge may be continuous, serrated, crenellated or otherwise configured.

Abstract: A one side plated metal of excellent appearance and quality can be obtained by dipping the material into a plating bath. In this case, one side of the material is oxidized just before it enters the bath so as to form an oxide film on that side and leave it unplated. As soon as it is pulled up from the bath it is maintained under reducing atmosphere so as to prevent adherence of the plating metal to the oxide film.

Abstract: A reusable security tag has an enclosure containing an element detectable by independent means and a cruciate sheet metal clutch lock. A pin for piercing a garment is secured at the end of a lever arm which is hinged to said enclosure for controlled movement into said clutch lock. Said pin is released from said clutch lock by application of a special tool to said enclosure for deforming said clutch lock to spread its jaws. Elliptical grooves around the shank of said pin increase the retentivity of said clutch lock without decreasing unnecessarily the tensile strength of said shank. This is a division of application Ser. No. 428,827, now U.S. Pat. No. 3,942,829 filed Dec. 27, 1973.

Abstract: First and second lenses are spaced apart in a common plane and provide respective first and second recorded representations of radiant energy issuing from an object surface point or region. The first representation is displaced relative to the second in measure depending on such lens spacing to spatially locate the image location of the object surface point relative to the second lens. With lens focal length known and magnification now determinable, object surface point distance outwardly of the lens common plane may be computed. Since the ray from the image location to the second lens node is also spatially located, the object surface point spatial location is defined.

Abstract: An enzymatically active product insoluble in aqueous medium is prepared by treating chitosan as an inert support with a dialdehyde, after which an enzyme is fixed to the support thus treated. The chitosan may be in powder-form or in flake-form, for example obtained by fragmenting a film of anhydrous chitosan. The enzymatically active product insoluble in aqueous medium may be treated with a compound containing an amino group and/or with a reducing reagent. The product may be freeze dried optionally in the presence of twice its weight of mannitol.

Abstract: A recorder has plural spaced radiant energy issuing locations juxtaposed with an expanse of a recording medium. Upon exposure of the medium, it is advanced relative to the locations by an amount fractionally related to the spacing of the locations and is again exposed. The practice is repeated with the cumulative recording medium advance being no more than the spacing of the locations whereby a single film frame accommodates plural exposures. The radiant energy issuing locations may be defined by slots in a grating member juxtaposed with the recording medium in a lens field of view.

Abstract: Method for making containers having enhanced emptying capability include a filling/emptying opening disposed closely adjacent the container sidewall and extending through integral top closure structure. The container sidewall has a portion contiguous with the filling/emptying opening which extends therefrom without radial step discontinuity, thus avoiding well formation adjacent the opening. A parison is stretched unidirectionally and transversely against restraint by a blow pin to avoid buildup of material in the sidewall portion contiguous with the filling/emptying opening and the stretched parison is blow molded to form the container.

Abstract: A process is provided for the production of a vegetable-based sweetened condensed milk in which a vegetable protein in the form of an aqueous solution or suspension is subjected to partial enzymatic hydrolysis and a mixture containing approximately 4 to 9 parts by weight of fats, 8 to 18 parts by weight of the treated protein, 0 to 14 parts by weight of lactose, 40 to 55 parts by weight of sucrose and 25 to 32 parts by weight of water is prepared. The proteins in suspension are subjected to a partial precipitation and the precipitated fraction is eliminated after the enzymatic hydrolysis step. A basic salt may be added to the mixture which may or may not have been subjected to the partial precipitation step. Partial precipitation is preferably brought about by addition of a calcium salt in a concentration of up to 0.001 to 0.1 M or by adjustment of the pH of the hydrolysed suspension to a value of from 4.5 to 7.

Abstract: A steel sheet having a two-layer film which exhibits excellent lubricating properties under press working can be manufactured by one step coating. In this case the coating composition after being applied to the sheet is irradiated with ionizing radiant energy, i.e., radioactive ray or electromagnetic wave, in an atmosphere containing an oxidizing substance.The outermost layer obtained is an uncured or unhardened semi-fluid layer but the layer contacting the surface of the steel sheet is a cured or hardened resin layer. If a lubricant is incorporated in the coating composition, or if the main component of the coating composition has one double bond per molecule, the result is more advantageous.

An apparatus for placing the supporting plate such that it can move back and fore freely on the bottom of the moving short wall of the mold is provided. In order to smooth the movement of the short wall of the mold, a lubricating agent may be placed at a portion where the long walls contact the short wall of the mold, or holes or grooves for supplying lubricating agent may be provided on both ends of the short wall of the mold.

Abstract: A flow restrictor is made by flattening a tube of flexible material about a member of cross-sectional characteristics representative of a desired flow passage, and securing the tube there, e.g. by rf welding. The member is then removed leaving a determinate flow passage in which problems of creep do not arise. The restrictor may have parallel to the flow passage a portion of the tube which is not permanently secured together so as to leave a by-pass which can be open to give a comparatively unrestricted flow passage or can be temporarily completely closed by external compression. A single tube may have in line a plurality of such restrictors with by-passes, the flow passages of the various restrictors being of different flow characteristics. The flow characteristic required is obtained by closing off the by-pass associated with the selected flow passage.

Abstract: A preselected volume of a liquified cooking medium is supplied to a continuous-flow system serving a cooking chamber. In the course of heating the supplied cooking medium prior to the cooking cycle, an overflow device is operative to remove that volume of the thus expanded cooking medium in excess of the preselected volume. On commencement of the cooking cycle, the overflow device is rendered inoperative.
