Patent EP-0231657-A2 (EP)
Inventor: FABIAN ELLIS
IPC: B29C48/32
Filed: 1986-12-24
Abstract: Apparatus for extruding a pliable, thin-walled tube comprising an extrusion and shaping die assembly (30) comprising an annular die body (34), a mandrel (36) supported within the annular die body, a mandrel extension mounted on the mandrel adjacent the die outlet, the mandrel extension (42) having a diameter less than the diameter of the mandrel and, a sizing disk (31) supported by the mandrel extension. Molten polymeric material is supplied through a die adaptor (33) to the die assembly under pressure to force the material through an annular extrusion flow channel (40) around the mandrel and out the die outlet thereby forming a moving tube (39) of the material. The mandrel extension (42) extends outwardly from the die (30) in the direction in which the tube is extruded, the annular die body having at least one fluid passageway (50,52) to channel fluid introduced under pressure into the annular die body axially through the mandrel (36) and outwardly from the axis of the mandrel extension (42) to form an air pillow adapted to cool and support the tube (39) around and spaced from the mandrel extension. The sizing disk (31) is adapted to restrict escape of the fluid and to define a chamber (54) in cooperation with the tube (39) of the polymeric material for confining the air pillow around the mandrel extension. This apparatus may be employed in a process to prepare a pliable, thin-walled tube.

Title: Box-shaped, hermetically closed, internally insulated panel and method of producing the same
Inventor: RIELLO VALERIO GIORDANO
IPC: E04C2/292
Filed: 1986-10-16
Abstract: A panel comprising a box-shaped element of metal sheet having inwardly bent edges designed to cooperate with mating bent edges of a panel cover, the bent edges of these two elements acting as fastening means between the box and the cover when a material capable of expanding into a rigid-type structure has been injected into the panel, whereby a one-piece, insulated and hermetically closed panel is obtained without the aid of any conventional type of fastening means. The panel is mainly intended for use in air conditioning and processing plants, especially when highly uncontaminated air is required. 
     A method for obtaining a panel according to the invention comprises the steps of forming a box-shaped element provided with particularly profiled edges, forming a cover with mating edges, fitting the edges of the cover into the edges of the box-shaped element, and injecting in the thus formed panel a material capable of foaming "in situ" while blowing out the air contained in the panel, upon polymerization of the foamable material, the latter forming a permanent bond which will hold the two parts of the panel firmly joined together hermetically.

Abstract: In an automatic cooking of cake, a gas sensor (10) and a weight sensor (9) are used to determine a total heating time. The initial weight of a food item (cake) (17) is measured by the weight sensor (9), and a time (T W ) proportional to a detected value of the weight sensor (9) is determined. The amount (ΔH) of change in humidity level until an arbitrarily chosen timing is detected by the gas sensor (10), and a time (T (ΔH) ) proportional to a detected value of the gas sensor (10) is determined. These times (T W ) and (T (ΔH) ) are added together to determine a total cooking time. With this arrangement, regardless of the kind and amount of cake and the shape of a vessel, the automatic cooking capable of giving a fine finish can be accomplished merely by selecting a single auto-key called a cake key.

Abstract: In a vice, it is proposed that the moving jaw 16 can be adjusted by a first thread 26 of a spindle 28 and that this spindle 28 is received in a threaded nut 34 by way of a second thread 32. The threaded nut 34 is axially supported and drivingly connected to the threaded spindle 28 by an overload coupling 50. In addition, it is braked by a rotary brake 37. When the clamping force at the moving jaw 16 increases, the rotary brake 37 becomes operative and the overload coupling 50 inoperative, so that the second thread 32 is screwed relative to the threaded nut 34. The two threads 26 and 32 have the same direction of helix, but a different pitch. When the second thread 32 is screwed relative to the threaded nut 34, the pitch difference between the two threads 26 and 32 acts simply to increase the clamping force. <IMAGE>
