A citrus fruit peeler comprises a handle or plate 10 having a guiding surface 13 from which projects outwardly a short cutting blade 16 carrying a glider plate 19 projecting at right angles on each side of its underside sufficiently to penetrate the peel only. Upstanding ribs 14 on each side of the plate 10 provide finger grips. An initial cut is made in the outer skin by a sharp tooth 20 after which the sharp edge 17 of the cutter is pushed into this cut and moved around the fruit to cut through the skin to a depth limited by the flat and rounded glider plate 18 at the outer part of the cutter 16. The device may have a long handle 29, Fig. 15, with a pivoted knife blade to fold inside or a sharp edge 31, for subsequently cutting up the fruit In Fig. 14 the glider plate 19 has a sharp rear edge 20 which can be used to make the initial cut instead of the separate tooth 20, Fig. 1, which can thus be dispensed with. An adjustable projecting guide 24, Fig. 14, may be used to supplement the outer guide surface 13, and so regulate the depth of peeling. The devices may be adapted for use in a machine with a relative motion of fruit and cutter.

Title: Electric power cables
IPC: B29C48/05
Filed: 1978-04-18
Abstract: In the case of heavy-current cables for relatively high voltages, there is a risk of so-called water trees forming in the plastic insulation. In order to avoid this, after manufacturing a cable having a conventional construction, namely a core (1), a first semiconductive layer (2), a polymer insulation (3) and a second semiconductive layer (4), a layer (5) having an active material is applied, which is covered by a covering layer (6) consisting of polymer material. The active layer has a content of 0.01-0.1 g of active material per cm<2> of layer surface. Water-soluble salts, salt-forming stable hydrates, or acidic and basic anhydrides, for example, are suitable as the active material. These materials have the property that they limit the relative humidity in their vicinity to a value below 70%, that is to say to a value at which water trees virtually no longer occur. In consequence, it is possible to dispense with watertight but expensive metallic cable sheaths. <IMAGE>
