Abstract: A system and process for making an eyeglass temple co-injection molded with a wire core are disclosed. An eyeglass temple is produced by injecting a first shot of temple substrate material into a mold followed by the shot injection of a portion of wire core into the substrate material while it is still molten or semi-molten followed by a second shot injection of additional molten or semi-molten material to completely fill the mold. The first shot of template substrate is provided in a viscosity and amount sufficient to support the wire core without contact by the mold or external support, and the second shot is provided in an amount sufficient to completely fill and pack the mold and lessen shrinkage problems during substrate cooling and hardening. This produces an eyeglass temple in a desired configuration having an entirely encased wire core. Optionally, a second material can then be overmolded onto portions of the temple.

Abstract: The invention relates to a device for producing goods for consumption, consisting of a fat mass, in particular a fat mass containing cocoa or a chocolate-type fat mass, said goods contains a large number of hollow moulds (1a, 1b) that can be filled with the fat mass (M) when the latter has been heated and is in a free-flowing state, the moulds being configured as depressions in a mould block (1). The inner surface of each hollow mould (1a, 1b) shell-shaped goods for consumption that are to be produced. The device also comprises a plurality of die-type cooling bodies (3a, 3b), which are displaceably mounted on a suspension device (4), a respective cooling body (3a, 3b) being lowered into a respective hollow mould (1a or 1b) and the outer surface of the respective cooling body (3a, 3b) determining the inner surface of the shell-shaped goods for consumption (M) that are to be produced.

Abstract: Gum manufacturing machinery and method of manufacturing gum is illustrated in which a gum loafing machine generates loaves of finished gum that are then subsequently run through a gum conditioner to more uniformly set the temperature and viscosity of the gum material prior to further processing. Upon achieving the appropriate conditioning level, a further forming extruder may be used to generate a continuous gum ribbon for subsequent rolling and scoring operations. The gum conditioner may include vertically stacked conveyors that have different operational modes including a first mode that provides a serpentine path for a long residence time and a second mode that provides a cascading path that avoids or bypasses much of the length of some of the conveyors to provide a shorter residence time. The gum manufacturing machinery may be used in an adjustable manner so as to accommodate difference gum recipes for different batches of gum product.

Abstract: The system for vacuum formation of a dental appliance is a fully automated vacuum formation machine for dental appliances, such as retainers and the like. The system includes a base having a perforated top vacuum plate in communication with a vacuum source. A heating unit is positioned above the perforated top vacuum plate, and a controller is in communication with the heating unit and the vacuum source for selective actuation thereof. A holder releasably receives a thermoplastic plate. The holder is selectively positionable vertically over the perforated top vacuum plate and a dental impression cast mounted thereon. The holder is positioned by a linear actuator or the like, in communication with the controller. A sensor is positioned adjacent the perforated top vacuum plate for measuring the thermoplastic plate's thickness as it is molded about the dental impression cast, and is communication with the controller.

Abstract: An apparatus for shock cooling a vulcanized tire includes a vulcanized-tire holding mechanism for holding a vulcanized tire and a tank for holding fluid to shock cool the vulcanized tire. The vulcanized tire is submerged in the fluid for between 4 and 60 minutes whereby the vulcanized tire reaches a predetermined temperature.

Abstract: A fastener strip is disclosed having permanently sealed, airtight portion and a reclosable portion capable of maintaining an airtight seal when closed. The permanently sealed portion is generally planar and essentially impervious to air flow. The reclosable portion includes a ridge and a trough, joined at their adjacent ends to a plug, which prevents air from leaking from the adjacent end of the reclosable portion. Additionally, a dam joins the plug to the first backing in an essentially airtight seal, and joins the plug to the second backing in an essentially airtight seal. A method and apparatus for sealing portions of a thermoplastic fastener strip are also disclosed. A method is additionally disclosed for vibrating and molding thermoplastic materials, in which a flow of malleable thermoplastic material is initiated and molded with an effectively dimensioned vibrator that is unitary, with a first matrix for guiding and molding the malleable polymer.

Abstract: A method and an apparatus for unloading plastic material products from a plastic material injection molding machine are disclosed. The method comprises the steps of unmolding the products from a mold of the injection molding machine and, after the step of unmolding, cooling the products on two product surfaces by contacting the two product surfaces with two corresponding cooling surfaces of a cooling apparatus. The apparatus is provided with corresponding unmolding devices and cooling plates.

Abstract: The present invention is directed to a method and an apparatus for forming glass articles from molten glass involving differentially cooling a plunger for press forming glass articles in a cooperative forming mold. More specifically, the method involves introducing cooling fluid into an inlet cooling cavity located in the upper portion of the plunger and causing the cooling fluid to flow from the inlet cooling cavity into a cooling passage located along the periphery of the nose portion and thereafter to flow into a outlet cooling cavity located in the upper portion of the plunger and thereafter exhausting the spent cooling fluid from the plunger.

Abstract: Large fittings or other structures are made by rotationally moulding a first component 18 of polyethylene and joining cylindrical pups 20, 22, 24 of polyethylene to the component by butt fusion joints 26, 28, 30. The structure within the boundary 50 is irradiated with gamma radiation followed by post-heating to remove free radicals. The extremities of the pups are shielded to prevent irradiation. Their capability to be joined to polyethylene pipes 12, 14, 16 by butt-fusion joints 32, 34, 36 is unimpaired. The irradiation introduces cross-linking to give improved properties such as impact resistance and stress crack resistance and to bring the fitting within the specification for polyethylene pipe for natural gas distribution. The joints 26, 28, 30 are made using differential heating of the ends to be joined to compensate for differences in melt flow index. Alternatively, the component 18 is slightly irradiated to lower its MFI before the pups are joined to it.
