Granted: 1973-02-10
Abstract: 1374289 Surface treatment of wood E G L ERIKSSON 3 Nov 1971 [3 Nov 1970] 51040/71 Heading DIP A method for treating the surface of wood, comprises pretreating the wood with a liquid hydrophilic substance substantially free of solvent and which facilitates penetration of the wood surface by an impregnation agent, the substance being caused to harden thereafter by subsequent treatment with the impregnating agent which reacts with the substance to form a polymer. The substance may be phenol or resorcinol. The agent may be an aqueous solution of hexamethylene tetramine, melamine formaldehyde or an intermediate reaction product of phenol and paraformaldehyde. Disproportionate penetration of the end surfaces relative to the other surfaces is prevented by initially applying an aqueous melamine resin to the end surfaces. This reacts with the phenol during the pretreatment to form a phenol insoluble polymer which prevents further penetration of the end surfaces. The phenol pretreatment may be effected at elevated temperature. Sulphuric acid or stannous chloride may be added to the phenol. The pre-treatment may be followed by a vacuum treatment. The subsequent impregnation may be at elevated temperature and pressure. This may be followed by a heat treatment which may be in two stages (a) oven at 80-140‹C for 1-2 hours and (b) hot press at 130-180‹C for 5-20 min. The surface finish is durable, abrasion-resistant and may be water repellant.

Title: Roller for peeling machines that are part of the industrial procedure in peeling tomatoes. It is made up of a metal bar covered with thermoplastic elastometric material, which was applied through a moulding procedure with an injection press.
Inventor: STEFANO CORRADI
IPC: A23N/
Filed: 1989-09-26
Granted: 1992-09-24
Abstract: On the tomato production line for the processing of peeled tomatoes and other products of this type a peeling machine is used that takes the skins off the tomatoes. These tomatoes have already been treated with thermic and/or mechanical processes. The machine is made up of a conveyor belt (the construction outline is illustrated in Fig.1) made up of rollers (seen in fig.1, seen in fig 2) that roll in pairs. While moving along, the tomatoes (seen in b fig 1) do not fall into the narrow openings between the rollers (seen in c fig. 1). They are transported along the production line while the peels fall to the floor (seen in d fig. 1) as they pass the above mentioned openings. To help the grip of the rollers on the skins, they are covered with rubber (seen in b fig 2) and are provided with small longitudinal tabs (seen in c fig.2). This rubber covering must be strongly adhered to the core of the rollers or the metal bar(seen in d fig.2) in order to avoid detachment. They are used is this industry and are produced through the vulcanisation of the rubber onto the metal treated with the appropriate adhesive. The patent being requested is for a roller in which the steel bar is covered with an inventive procedure. The bar in question is covered in thermoplastic elastomer that has been applied to the steel insert through an injection moulding system. This procedure gives the advantage of using a thermoplastic material that is recyclable and economic.

Abstract: Machinery consisting of a plurality of pairs of fixed voids 15 equal to the plurality of winding units 13 operating simultaneously in the machinery. In each pair of voids 15, one void is occupied by a functional unit 13 with an operating coil 19 while the other will be occupied by another functional unit 13 with an empty coil 17 which is called when the first functional unit 13 is by now a full coil 21 and the wire 9 must be passed continuously from one unit to the other. Each functional unit 13 is composed of a single coil, is modular, can be moved on command and made functional on command in accordance with the conditions of the actual coil. The known coil-winding device 11 that passes the wire 9 from a full unit 21 to an empty unit 17 is fixed to the stationary frame 28 which contains the voids 15 in which the coils are housed. When the movable single-coil unit 13 according to the invention is approaching the "full coil" condition 21 it indicates its state, so that a functional unit 27, human- controlled or automatic, takes another, empty, movable single-coil unit 17 from the magazine and brings it up alongside the unit with the full coil 21 ready to be taken. Once the wire has been changed over the said first functional unit 13 with the full coil 21 is taken to a magazine by the means 27 provided, vacating the hitherto occupied void 15, which void can be occupied by another empty single-coil 17 functional unit 13, when the said second unit, which has just been made functional 19, reaches the full-coil condition 21 and indicates its state. The said single-coil functional unit 13 can travel about e.g. on carriages; the means 27 provided for effecting these movements may be a carriage guided by a man, a wire- guided or remote-guided carriage, a magnetic-track means or the like, provided always it is a means which operates primarily on the floor. These arrangements eliminate all the grasping, lifting and overhead transport movements typical of the machinery used hitherto and bring enormous advantages to the automation and/or mechanization of the machinery.
