摘要:
An end mounting (2) for pivotally mounting a housing (5) of a ram (1) to a structure (3) is formed from a single solid piece of material. The end mounting (2) comprises a mounting block (9) which is secured to the structure (3), an end cap (10) which is sealably secured to the housing (5), and a connecting portion (14) which extends between the mounting block (9) and the end cap (10). The connecting portion (14) is of hour-glass shape, cross section and extends the width of the mounting block (9) to form a plastic hinge. The connection portion (14) defines a pivot axis (18) at the waist (19) of the hour-glass shape about which the end cap (10) and the mounting block (9) are pivotal relative to each other.

A product-carrying tray (1) has longitudinally slotted end members (3) for sliding engagement on guide rails in a conveyor installation or storage unit. Transverse edges (2) of the tray are provided with coupling members (5) for interengagement with other like units also accommodated on the guide rails. In the illustrated embodiment, the coupling members (5) are defined by interengaging hook structures consisting of projecting portions (7) and laterally extending end portions (6). The tray of the invention is especially suited to accommodating food products within a storage or treatment chamber. The tray may however also serve as a product-carrying element in a conveyor installation. Apart from the hook-type interconnection illustrated, a multiplicity of other interconnecting arrangements may be provided, including, inter alia, alternative mechanical structures and magnetic coupling.

The present invention relates to a rejecter for a product sorting system (1) comprising at least two different co-located rejection means (3, 4) wherein each rejection means is independently activatable to deflect a product from a sorting stream.

摘要:
In an optical inspection system for edible natural products, the products are passed through an inspection region in which light is directed onto the products from optical units (61 and 62) during passage of the products through the inspection region. A sensor (66, 67) detects light returned from the products passing through the inspection region. The invention provides an optical system consisting of lenses (84, 85, 86) for directing light from source units (61, 62) onto the products passing through the inspection region substantially at a specified target region (69) within the inspection region. The light sources (61, 62) comprise light emitting diodes (81, 82, 83) and the focussing is achieved by outer rows of diodes (82, 83) being displaced outwardly relative to the axes of respective cylindrical lenses (84, 85) of the optical system so that light originating from the outer rows of diodes (82, 83) converges towards that passing along the central axis (68) extending from a central row of diodes (81) through central lens (86) to the target region (69), light from all three rows of diodes (81, 82, 83) being therefore focussed substantially at the target region (69). Suitably the system comprises two lens assemblies (61, 62) working in association with a centrally located sensor assembly (66, 67). Advantages are reduction in the number of LEDs required at an inspection station, reduction of dirt build-up on sensor window (71) by virture of the target region (69) being located at a greater spacing than in constructions using unfocussed light, and substantial elimination of responsiveness to spurious signals originating beyond the target zone (69).
摘要:
A valve (61) for enabling release of pressurized steam from a pressure vessel has a displaceable closure member (67) which is maintained in its closed disposition by exposure to the pressure of the steam within the pressure vessel. The closure member (67) is displaced between its closed disposition and an open disposition by a double-acting actuator (69), suitably an air-driven piston/cylinder device, the closure member (67) being preferably mounted at one axial end of a spindle (68) extending between the closure member (67) and the actuator (69). The closure member (67) is suitably mounted for substantially metal-to-metal contact with a valve seat portion (63), without interposition of any sealing element, preferably for substantially vertical displacement between its closed and dispositions.
摘要:
A pressure vessel (1) for steam treatment of product to be peeled in a steam peeling system has substantially the shape of a sphere with opposed flattened side surfaces. The pressure vessel (1) is rotatable and has at least one internal lifting feature (51a, 51b, 51c) for entraining and raising product relative to the axis of rotation of the pressure vessel (1) during rotation of the pressure vessel (1). The pressure vessel (1) also at least one internal region (53) which is closed-off against ingress of steam during product treatment, said region (53) defining a steam saver. The pressure vessel (1) may be incorporated in a product treatment system also including a batcher for delivery of product to be peeled. The system may provide for accelerated pressure drop on completion of a peeling operation, as well as including arrangements to minimise release of entrained solid matter and/or odours in exhaust steam. A control system enables unproductive displacement of the pressure vessel to be minimised.
