摘要： A die assembly for forming wax patterns is provided, including at least two cooperating mold portions together defining a main cavity, a runner in communication with the main cavity, a temperature sensor disposed proximate the runner, and a counter coupled to a mold portion and connected to the temperature sensor. When wax is injected through the runner into the main cavity, the temperature sensor measures an increase in temperature and the counter registers an injection cycle. An injection molding method also is provided with injection cycle counting.

摘要： A molded honeycomb material is obtained by subjecting a mixture of a raw material powder and a binder to extrusion molding. In the honeycomb material, no open pores are present, and the binder includes a thermoplastic material which is molten at the molding temperature. A process for producing the above molded honeycomb material includes heating a mixture of a raw material powder and a binder to a molding temperature to melt the binder, subjecting the mixture to extrusion molding, and cooling and solidifying the extrudate. The honeycomb material has a small partition wall thickness and can be mass-produced without impairing the product quality.

摘要： A biaxially-oriented polypropylene (BOPP) film with improved barrier properties, and a method of making the film are provided. The MVTR of a multi-layer BOPP film is improved by blending wax in the core layer resin, and providing a polyolefin cap layer on each side of the core layer. Significant additional improvements are seen when the film is heated at a temperature below the melting point of the core layer resin, below the distortion temperature of the film, and above the melting point of the wax for a time generally extending from at least five minutes to several hours or more in length, depending on the temperature.

摘要： A wafer (10) providing transfer sheets of semipermeable membrane (21). Such wafers include peripheral support means (11) defining a generally cylindrical ring and having inside (14) and outside faces (15) and upper (12) and lower (13) faces and, a plurality of transverse sheet membrane sleeves (16) carried within the peripheral support means. Apparatus (60) for the separation of a fluid into permeate and retentate portions comprises a plurality of transverse sheet membrane wafers (10), vessel means (61) providing a first port (68) for receiving the fluid, a second port (69) for withdrawing the retentate and a third port (70) for withdrawing the permeate, means for compressing (74) the plurality of wafers in axial alignment, and permeate chamber means (72) within said vessel, separate from the feedstream and the retentate by the means for compressing (74) and peripheral support means (11). Separate methods are also provided for the manufacture of the wafers as well as for the separation of fluid feedstreams into permeate and retentate portions. A method of the latter type includes the steps of feeding the fluid into a module containing a plurality of semipermeable membrane sleeves arranged chord-wise in parallel alignment and oriented perpendicularly with respect to the longitudinal axis of the module; providing separate chambers for the permeate, communicating with the interior of the sleeves, and for said retentate, communicating with the areas between the membrane sleeves; and removing the permeate and retentate from the module.

摘要： A method of making epoxy molds for making wax patterns have metal posts disposed therein which transfer compressive forces between the force applying members of the press in which the molds are located. The metal cylinders in the upper mold section have right hand screw threaded axial bores and the metal cylinders in the lower mold section have left hand screw threaded axial bores. The metal cylinders are connected together when the mold sections are poured by connecting studs which have oppositely threaded ends. After the epoxy cures, screw drivers are inserted into the threaded bores from outside the molds and the connecting studs are turned in a direction which causes the mold sections to separate in turnbuckle fashion. Accurate alignment of the inner end faces of the cylinders in the parting surfaces of the mold sections is achieved by having the metal posts connected during the mold pouring steps.

摘要： A laser wax joinery method and apparatus are disclosed. Molded wax segments, such as those used to produce patterns for investment casting, are immobilized relative to one another, with their conforming marginal edges in abutted relationship, on a two axis rotatable tilt table. A laser beam of controllable energy density scans the edges of the wax segments, forming therealong a wax weld pool that, while molten, is maintained generally horizontal by rotation of the tilt table. The laser beam's energy density is modulated to correspond with the varying thickness of the edges to be joined. A laser beam delivery system includes a process robot and a lens and mirror system for directing the beam generally vertically toward the surface of the wax segments. Shrinkage by wax dripping or filler vaporization is avoided by precisely controlling the energy density adjacent the weld joint. By coordinating the operation of the tilt tables and the laser beam delivery system under the programmable control of a master controller, it is possible repeatably to produce strong, smooth, uninterrupted weld joints. In modifications, the wax weld pool is controlled by preparatory covering of the surface adjacent the abutted edges with a fluid-resistant, conformable, and laser beam-transmissive polyethylene, or thermally conductive metal foil, material that, while transmitting, or conducting, a substantial portion of the laser energy to the wax segments, prevents loss of wax by dripping. In another modification, the weld pool is controlled by multiply scanning the abutted edges at a reduced energy density.

摘要： An injection nozzle assembly is used for molding a plurality of articles having accurate dimensions without causing a sink mark to appear in the molded article. The injection nozzle assembly comprises a body which is heated to a temperature higher than the melting point of thermoplastic material. A cylindrical bore is formed within the body, and an outlet port is formed at one end of said cylindrical bore. A plunger moves within the cylindrical bore between a first position near the outlet port to a second position which is remote from the outlet port. A first feed line supplies the molten thermoplastic material and a second feed line feeds high pressure through passageways that are formed within the body. The plunger is formed within a first passageway connecting the feed line with the outlet port when the plunger is moved to the second position. The pressure at the outlet port is reduced by the movement of the plunger from the first position to the second position.
