Abstract: A pelletizer for making pellets from a liquid or semi-liquid food product has two molding rolls between which the food product is formed into pellets. The rolls have teeth of complementary shape, and the teeth of at least one roll have axially spaced apart recesses. The rolls are cooled with a refrigerant during the molding operation. By the means of the pelletizer, frozen pellets are made from a liquid or semi-liquid food product which, prior to molding, is refrigerated into moldable consistency before being supplied to the nip between the two cooperating molding rolls which are cooled during the molding operation so as to form surface-frozen pellets which are thereafter subjected to final freezing.

Abstract: A door roller provided with an engagement arm which is capable of being engaged with, by an engaging member attached to an upwardly bent end of the engaging arm, a guide groove formed with a downward opening longitudinally along a lower frame of a window structure for preventing a sliding door from an accidental removal. An inner housing retaining a tire shaft is rotatably pivoted to an outer housing of the door roller via another axis parallel to the tire shaft. The engagement arm which is engaged with the inner housing by way of an engaging mechanism is disposed freely movable upwards and downwards in relation to the outer housing. The engaging mechanism is located at a further position than the tire shaft from the another axis such that the engagement arm may be moved vertically, when the tire has been ascended or descended by a predetermined amount, by a larger amount than or an approx. equal amount to the predetermined amount in relation to the outer housing.
Abstract: An anti-rust cover for a disc rotor used in a vehicle disc brake. It is characteristically provided, as a means of attaching the same to the dust cover, with a combined engaging mechanism composed of at least three engaging members in all, i.e., at least one inside engaging member and at least one outside engaging member, arranged alternatively with a predetermined circumferential phase difference on the inner surface thereof confronted to the dust cover, near the outer periphery of the anti-rust cover. It is to be snugly attached to the dust cover by being fitted-in by the outer periphery of the dust cover between the inside engaging member(s) and the outside engaging member(s).
