Abstract: To prevent coupling breakage between an elastic body and an outer ring due to friction heat of an armature and a rotor, an solenoid clutch coupling is provided with an elastic body (3) elastically coupling a hub (10) attached to a rotation shaft (6), and an outer ring (20) coupled to an armature (5) solenoidally moved close to and apart from a rotor (4), a sleeve (40) buried in an outer peripheral portion of the elastic body (30), a fit layer (32) constituted by a part of the elastic body (30) in an outer peripheral side of the sleeve (40) and attached to an inner peripheral surface of the outer ring (20), and non-cylindrical surfaces (21a) engaging with the fit layer (32) in a circumferential direction, and axial stoppers (23, 24) to an outer periphery of the elastic body (30) in a sleeve (21) of the outer ring (20).

Abstract: An apparatus for filtering fluid substances is used with a machine for injecting meat products. The device comprises a container (4) comprising filter units (3a, 3b) communicated independently with a suction outlet (6) through respective valve devices (9a, 9b) that can be moved between open and closed positions. Each filter unit (3a, 3b) is mounted to the end of a pivoting connecting conduit (22a, 22b) which is connected to the respective valve device (9a, 9b) thereof. Each conduit (22a, 22b) and filter unit (3a, 3b) can pivot between a lowered operating position, whereby the valve device (9a, 9b) is open and the filter unit (3a, 3b) is submerged in the fluid, and an erect maintenance position, whereby the valve device (9a, 9b) is closed and the filter unit (3a, 3b) and the fixing means (13) thereof emerge out from the fluid and are accessible so that they can be released.
