Abstract: A surface-coated product consists of a supporting element in the form of a thin-walled hollow profile of plastic with a layer of wooden veneer bonded onto the supporting element. The product is manufactured by the supporting element being continuously fed into a closed space together with the softened layer of veneer and a layer of glue therebetween, in order to be subjected to pulsating pressure action and heat from a vibrator via a vibrator head having a pressing surface adapted to the product. A circulating airflow keeps the atmosphere in the space at room temperature with relatively low moisture content. When the vibrator head is removed from the veneer surface in each working stroke, a vacuum is formed which rapidly removes the moisture from the wood and solvents from the glue, respectively. At the abutting of the head against the veneer surface, extracted vapours from said fluids are pumped away sideways. The bonding course is performed quickly, without time for the thin-walled supporting element to be influenced by heat or solvents, whereby deformation and dimensional deviation of the product obtained is prevented. <IMAGE>

Abstract: An energization circuit for a microwave oven employs a PTC thermistor to eliminate high transient current surges resulting from energization and deenergization of induction elements therein to provide circuit protection both during oven start and operation. The energization circuit comprises first and second parallel circuit portions for energizing a transformer used to energize a magnetron that produces microwave energy, the first circuit portion including a normally open start switch and a current limiting PTC thermistor coupled in series relation and the second circuit portion including a relay operated switch, a relay for operating the relay operated switch, and a relay circuit portion connected to the first circuit portion between the start switch and PTC thermistor for energizing the relay upon closure of the start switch and then through the PTC thermistor upon opening of the start switch. During start-up, power is briefly supplied to the magnetron through the PTC thermistor to reduce high current surge flow to the transformer until the relay operated switch closes and supplies full power to the transformer and thus to the magnetron. The relay first is energized directly through the start switch upon closure of the latter and then by reverse current flow through the PTC thermistor upon closing of the relay operated switch and opening of the start switch.

Abstract: The invention relates to a chain guide for a chain saw, with a pair of side plates, between which a spindle is arranged in a fixed position, and a chain wheel which is rotatably mounted relative to the spindle. The chain wheel is rotatable about the spindle and serves to direct the saw chain, moving at high speed, around the edge of the guide. Roller bearings are arranged between the spindle and the chain wheel. A pair of annular seals are in each case arranged between the chain wheel and one of the side plates and between the chain wheel and the other side plate. Each of the seals has an annular bead which rebounds at an angle and is in flexible contact with a surface of the chain wheel or one of the side plates. If no lubricant is supplied, a lubricating opening formed in each side plate is closed by a flap on an annular seal or an elastic valve device which is inserted into a central bore of the spindle. When lubricant is supplied under pressure via the opening, the flap or the valve device yields on account of the elasticity and enables the roller bearings to be supplied with grease.

Abstract: A dowel for insertion into a borehole in a structural unit includes a dowel body and a spreading member. The dowel body is axially elongated and has a cylindrically shaped outside surface with a bore extending axially through the body. The body is formed of a sintered dry powdered metal made up primarily of iron and having a weight in the range of 5 to 7 g/cm3. Phosphorus in the range of 0.1 to 1% can be added to the dry powdered material to increase its cohesion. Further, the sintered material can be reinforced with fibers. An axially extending portion of the bore is conically shaped and the spreading member is similarly conically shaped for radially expanding the dowel body within the borehole.

Abstract: Amongst the problems facing surface-independent divers are the supply of oxygen and, especially at greater depths, the chilling, which with known devices is aggravated by the fact that the oxygen supplied is very cold. For the solution of both these problems, a unit is proposed comprising a device for fragmenting hydrogen peroxide 1 by means of a catalyzer 13 and a member for separating water from the oxygen produced in the fragmentation. The separation member comprises a condenser 2, which also cools the oxygen, which is over- hot owing to the production method, to the point where the respiratory gas which is mixed herewith acquires a temperature which is favourable to the diver. <IMAGE>
