Patent number: 6071445Abstract: A method of forming plastics which comprises the sequential steps of cutting a plastic piece from a sheet of plastic, heating both sides of the plastic piece by contact heating, molding the heated plastic piece into its end-shape by press-molding, and cooling the heated and molded plastic piece into its end shape by air cooling means. In the preferred embodiment, the plastic piece, which may be laminated on one or both of its sides, is heated by use of a heating press which compresses the plastic piece thereby preventing "wrinkling" or warping of either side of the plastic piece. Thereafter, in the preferred embodiment, the heated plastic piece is positioned in a press-molding mechanism which comprises specially made male-female dies. Preferably, the air cooling step of the method takes place during the latter part of the press-molding step whereby both steps are, at some period, occurring concurrently.Type: GrantFiled: June 30, 1998Date of Patent: June 6, 2000Inventor: Curtis D.

Patent number: 5039294Abstract: An adjustable powder compacting device for compacting a powder such as a cosmetic powder includes a control unit which electrically monitors and controls a hydraulic ram operated punch to compress the powder into a cup. The control unit causes the punch to perform: an approach stroke with a first regulated preset punch speed until the punch contacts the powder and exerts a first pressure on it, a debubbling stroke with a regulated second preset punch speed until the pressure exerted by the punch reaches a second preset pressure, and a compacting stroke at a constant third preset pressure for a preset period of time. These preset speeds and pressures are easily adjusted so that proper evacuation of gases from the powder and optimal compacting is readily achievable when the consistency of the powder changes. In specific embodiments, the device includes a rotatable disc for causing successive volumes of non-compressed powder to be compressed by the punch.Type: GrantFiled: May 26, 1989Date of Patent: August 13, 1991Assignee: L'OrealInventors: Jean Gautier, Jean-Pierre Crepet

Patent number: 4819177Abstract: A method for curing rubber in a heated mold in which the temperature of the mold is measured after closure and variations in temperature from an optimum cure temperature are used to adjust elapsed cure times which decrement an optimum cure time. The adjustment of elapsed cure time is determined by an algorithm which utilizes the 18.degree. F. (10.degree. C.) doubling rule; that is, that the rate of cure doubles for each increase in temperature of 18.degree. F. (10.degree. C.) and halves for each decrease in temperature of 18.degree. F. (10.degree. C.). Accordingly, the algorithm reduces the cure time remaining at a rate exceeding the actual elapsed time if the temperature of the mold is measured and determined to be above the optimum or set point temperature, and conversely, the cure time remaining is lengthened by reducing the cure time remaining at a rate below the actual elapsed time rate if the measured temperature of the mold is below the set point temperature.Type: GrantFiled: June 19, 1987Date of Patent: April 4, 1989Assignee: Systran CorporationInventor: John R.
