Abstract: ABSTRACT OF THE DISCLOSURE      A process is described for the preparation of a natural cheese product having an intensified American cheese flavour.  The American cheese flavour appears, at least in part, to be as a result of the free C2 to C10 fatty acid content of the cheese product. Cheese products having the intensified American cheese flavour possess a C2 to C10 fatty acid content at least about 10 times the C2- C10 fatty acid content of conventional aged American-type cheeses.  The process comprises providing a medium containing milk protein and fat, setting the medium to provide a coagulum, cutting the coagulum to provide curd particles and whey, separating said curd particles from said whey, mixing said curd particles with enzyme and curing said curd particles at a temperature above about 50°F for a period of time sufficient to provide a total free percent by weight and a free C4 fatty acid content of at least about 0.32 percent by weight, said lipolytic enzyme being selected from enzyme extracted from the throat tissue of calves, lambs and kids and said proteolytic enzyme is an exopeptidase having high pro-teolytic activity but only minor diastatic action.  The cheese product having the highly intensified flavour is particularly useful for mixing with other food products such as unaged cheeses and bakery products in order to impart an American cheese flavour to such products.

Abstract: INVENTION: METAL COATING PROCESS          INVENTOR:  Leonardus Joseph SAVELKOULS     Abstract of the Disclosure Metal substrates, such as steel sheeting or steel plates of large containers and similar structures, are coated in a continuous operation by arranging a polymer stratum that compris-es a heat or melt bonding composition in contact with the metal substrate and by directing electromagnetic radiation in the radio frequency range through the polymer stratum without substantially heating the latter onto the substrate for briefly heating a sur-face area of the substrate to a temperature where the heat or melt bonding composition in contact with the substrate is activated to form a heat or melt bonded connection between the polymer stratum and the metal substrate. The heated surface area is moved continu-ously so as to bondingly coat the surface of the substrate, e. g. the fuel-receiving compartments of a tanker, with the polymer stra-tum. An apparatus for the coating process is disclosed and compris-es an inductor loop for directing radio-frequency radiation through the polymer stratum onto the metal substrate. The inductor loop can be made to conform with the surface of the substrate that is to be coated and made resistant against corrosion.

Abstract: ABSTRACT OF THE DISCLOSURE         A single lever control for the throttle and clutch of a marine propulsion device including a housing pivotally supporting both a main control lever and an auxiliary warm-up lever, a throttle lever, and a gear shift lever.  The throttle lever is alternately operable to regulate the setting of a remotely located engine throttle in response to movement of either the main control lever from a neutral position or the warm-up lever from an idle position.  The gear shift lever is operable to shift an engine clutch in response to initial movement of the main control lever from the neutral position.          A lock-out lever mounted inside the housing cooperates with a lock-out plate carried by the warm-up lever and with a recessed, arcuate surface on the gear shift lever to prevent movement of warm-up lever when the main control lever is displaced from the neutral position and to prevent movement of the main control lever when the warm-up lever is displaced from the idle position.           In one embodiment, the locking arm of a locking mechanism carried by the main control lever cooperates with a notched index plate mounted on the exterior of the housing and coaxially with the control lever pivot axis to releasably lock the main control lever in the neutral position.  In another embodiment, the index plate and the control lever are arranged to afford selective adjustment of the angular orientation of the main control lever so it will be substan-tially vertical when in the neutral position irrespective of the angular orientation of the housing to the horizontal.

Abstract: IN THE UNITED STATES PATENT AND TRADEMARK OFFICE "DRUM-SHAPED CARDBOARD CONTAINER, AND METHOD OF ITS MANUFACTURE". A stack of flat cardboard blanks, which may be preprinted with contents or advertising matter, and having approximately the dimensions of the developed circumference of the container, and slightly larger in circumferential direction, is positioned over a transport conveyor which peels off one blank at a time, the flat blank being transported past a gluing  station to apply a strip of adhesive along a longitudinal edge of the blank parallel to the edges of the drum when the container is formed.  The blank is then wrapped around a mandrel by gripping jaws.  The mandrel has the general shape of the container and forms the blank into an open sleeve with overlapping edge portions of the blank which are adhered together by the adhesive previously applied.  The adhesion may be done under pressure and with application of heat, for example by applying a heated stamping block thereagainst.  The mandrel may also be heated.  A bottom is then inserted into the then formed cylinder, for example in form of a shallow dish inserted upside-down, with the edges of the cylinder rolled thereover to space the bottom of the cylinder from the bottom plane of the so formed container.  The container may be circular-cylindrical polygonal-cylindrical, for example rectangular or square in cross section, and is particularly suitable for transporting pulverized grainy or lumpy goods, such as soap powder, and the like. 1a

Abstract: Abstract of the Disclosure Disclosed herein is an earth boring bit of other-wise conventional construction except for the bearing and cutter retention.  A snap ring is used to retain the cutter, the grooves that receive the ring and the ring construction being such that the ring is forced into the retainer groove when the cone is thrust inward.  The ring cannot therefore accident-ally return to its assembly position to permit cutter loss.      This enables the use of exclusively frictional bearings and retainer means of exceptional strength and reliability.

Abstract: CRANE CONVERSION METHOD                 ABSTRACT OF THE DISCLOSURE             Method and apparatus altering or retrofitting an excavating crane such as a trench hoe, back hoe, etc.  into a lifting crane suitable for scrap handling are disclosed.  The conversion is accomplished by outting V-shaped notches into the side plates of a conventional at a point adjacent and outboard of the point of connection between the main hydraulic piston and the main boom; bending the boom so that the edge surfaces formed by the sides of the V-shaped notches are brought into abutment and welding the same together.  In this fashion the geometry of the main boom is altered without any necessity for altering either the pivot point, the stroke of the pistons, or any other portion of the overall crane in order to change the lifting arc and permit a greater lifting capability.  By this modification, the crane becomes suitable for scrap handling wherein the problem is mainly lifting sub-stantial weights, as contrasted to excavating operations where the reach of the boom arm is primary importance.  The inven-tion also contemplates applying reinforcing plates adjacent the weld point to strengthen the completed unit.

Abstract: ABSTRACT OF THE DISCLOSURE:     A dual induction system has a primary induction passage to direct a fluid charge into a cylinder to swirl therein and a secondary induction passage to direct a second fluid charge into the cylinder in such a direction as to impede the swirl of the first fluid charge and lower the "swirl ratio" within the cylinder.  A primary throttle valve controls the first fluid charge while a secondary throttle valve which is coordinated with the primary and remains closed until the primary opens wider than a predetermined amount, controls the second fluid charge.  When only the primary throttle valve is open a high "swirl ratio" of 1.5 to 6 prevails in the cylinder while when both open the "swirl ratiol" drops to 0.5 to 1 and simulta-neously provides a high volumetric efficiency.
