Title: Re-closable bags and the production thereof
Inventor: CLAXTON NIGEL ERVINE
IPC: B65D33/25
Filed: 1983-03-22
Abstract: A multi-layered bag including synthetic plastics material has attached to opposed walls the interengageable male and female elements 18, 16 respectively of a strip fastener. The bags may be produced in strip form with each bag joined to the adjacent bags by means of welds extending transversely of the strip. Each transverse weld is associated with a transverse line of perforations or weakness whereby the bags can readily be separated from one another. Production of the material for the multi-layered bags can be by way of co-extrusion of the materials or by lamination. According to one described method, two sheets of suitable material, preferably in the form of elongate webs, 26, 28 are laminated one to the other. In another form, a tube of material is externally sheathed thereby to provide the laminate. The tube in this latter form, or one of the sheets in the first form, carry the male and female parts of the snap-engaging releasable connection. After production of the laminated material, welding and perforating operations are performed to produce the strip of bags. <IMAGE>

Patent GB-2124573-A (GB)
Title: Carriage, in particular for sorting apparatuses
Inventor: CANZIANI FRANCESCO
IPC: B65G47/96
Filed: 1983-06-13
Abstract: A carriage for sorting apparatus has a carrier plate (3) which is pivoted to a support (8) which is disposed on a conveyor belt (2) or band which moves along a predetermined path. Pivoted to the support is a lever element (13) which is actuable by cams (17) disposed along the path and which causes the carrier plate to tip towards a desired side, to effect the unloading or discharging operation. A cam follower (16) on engaging the cam (17) produces rotation of the lever element about an axis B-B to disengage the lever element from a pin (10) and, subsequently, rotation about an axis A-A so as to move a pin (11) extending through a slot (20) in the lever element and so rotates the carrier plate about the axis of the pin (10). When the cam follower is disengaged from the cam, the lever returns to its initial position and restores the carrier plate to a level position under the action of gravity. <IMAGE>

Title: Apparatus for cleaning granular material
Inventor: BATT PETER DORRINGTON
IPC: B07B1/22
Filed: 1983-07-08
Abstract: A rotary cleaning apparatus has a horizontal or slightly inclined perforated drum (10, 12). The granular material is charged into the interior of this drum. The larger particles remain within the drum while the smaller particles fall through the perforations. The smaller particles fall onto an inclined spreader plate (20) which has a lower edge terminating at an angle to the direction of flow of the particles down the plate, so that the particles drop off the plate at different positions across the width of the apparatus resulting in a falling curtain of particles across the apparatus. An air blast is then passed through the curtain, and the lighter of these particles is separated from the heavier. <IMAGE>
