Title: Improvements in or relating to an apparatus for the selective automatic discharging of items from a continuous conveyor
IPC: B65G47/50
Filed: 1959-05-25
Abstract: 894,534. Endless conveyers. PEZZERA, E., and PEZZERA, C., [trading as TERMOAEROTECNICA INDUSTRIALE OFFICINE F.LLI. PEZZERA]. May 25, 1959, No. 17749/59. Drawings to Specification. Class 78 (1). In a sorting apparatus, articles travelling on a conveyer are automatically discharged at various positions along the conveyer, each article being assigned to a discharge position as it passes a single control station. Discharge is controlled by arms which are pivotable under the control of electromagnets to deflect articles from the conveyer or to let them pass to a subsequent discharge point. As an article passes a control device a push-button is depressed according to which position it is desired to discharge the article. Sensing means such as photocells, capacitive circuits, or mechanical members, spaced at substantially equal distances along the length of the conveyer detect the passage of an article. A sensing means is placed just before each deflector arm and a further sensing means precedes the first of these. Depression of a push-button energizes a first relay and, as the article passes the abovementioned further sensing means, a second relay is actuated which de-energizes the first relay. Assuming the article is to be discharged at the second discharge point, as it passes the sensing means at the first discharge point, a third relay is actuated which de-energizes the second relay and similarly a fourth relay is actuated as the article passes the sensing means at the second discharge point. Associated with these relays are further relays and the circuitry is such that on actuation of the fourth relay and its associated relay, the electromagnet controlling the second deflector arm is energized so that the article is discharged.

Abstract: 649,252. Seaming and cutting non-metallic sheet material. COMMUNICATIONS. PATENTS, Ltd. 'July 7, 1947, No. 17855 [Classes 31 (i) and 42 (i)] [Also in Group XI] In the production of an article from sheet or strip thermoplastic electrically non-conductive material, the material is seam-welded by pressure and high-frequency electric field heating, the pressure and heating being used simultaneously to reduce the thickness of the material alongside at least a portion of an edge of the seam-weld so as to enable subsequent detachment of the article from the remainder of the material to be effected by merely pulling the respective portions apart by hand, the heating and pressure being maintained during the whole of the time that the thickness of the material is being reduced. An electrode for carrying out this method may consist of a flat metal plate with a chamfered edge, co-operating with a surface which lies in a plane normal to that of the plate, so as to produce a weld of varying thickness ; the electrode is stopped short of the co-operating surface. Alternatively the electrode may consist of an unchamfered plate set obliquely to the co-operating surface, or it may be stepped or recessed and may have relatively movable sections to enable the depth of the step to be varied. According to the Provisional Specification the electrode may eventually contact the co-operating surface to cut the article from the material, or the article may be severed from the material along a portion of the weld and the material reduced in thickness along another portion ; the co-operating surface may in these cases be of insulating material arranged over a metal electrode.
