Patent CA-2155386-A1 (CA)
Title: Fan Motor/Impeller Mounting System
Inventor: KNIGHT JOHN T
IPC: F04D29/62
Filed: 1995-08-03
Abstract: A centrifugal air blower has a housing with an inlet side wall through which a circular air inlet is formed. A cylindrical electric drive motor coaxially extends through the inlet opening and is drivingly coupled to a centrifugal impeller rotatably disposed within the housing. The motor is supported on the inlet side wall by a mounting system including a plurality of metal mounting rods each having an inner end, an outer end, and an elongated intermediate portion. The inner rod ends are welded to circumferentially spaced locations of a belly band structure coaxially clamped to the drive motor, and the outer rod ends are connected to resilient support assemblies arranged in a circumferentially spaced array on the outer side of the housing inlet side wall around the blower inlet opening. To provide the mounting system with a high degree of stiffness with respect to mounting system loads directed transversely to the motor drive axis, while at the same time providing the mounting system with a high degree of torsional flexibility, each of the intermediate rod portions is positioned to longitudinally extend adjacent and generally parallel to a line extending from the outer end portion of the rod to the center of gravity of the combined mass of the drive motor and impeller.

Title: Manufacturing method for plastic forming molds
Inventor: KITANO MINORU
IPC: C23C16/01
Filed: 1995-08-25
Abstract: A manufacturing method for forming plastic dies in which a metal layer is formed on a mandrel surface at a rapid rate of deposition and with few modifications. The mandrel surface is heated to the metal carbonyl's deposition temperature and by introducing a metal carbonyl vapor on the mandrel surface a metallic layer is formed. The deposition temperature of the metal from the metal carbonyl vapor is remarkably faster than temperatures from electro-casting. Compared to electro-casting with the same Ni, this is 10 times faster and the productivity is remarkably higher. Also, the metal's deposition from metal carbonyl vapor is done evenly regardless of whether the mandrel shape is irregular. Furthermore, separation is easy when the surface of the mandrel comprised of alloy Al or Al forms a heat resistant layer and when the heat resistant resin layer is burnt off after the metal carbonyl's metallic layer is formed.
Patent CA-2159095-A1 (CA)
Title: Process and device for tempering molding tools for processing plastics
Inventor: LIEHR ERICH
IPC: B29C35/02
Filed: 1994-03-19
Abstract: Process and device for tempering molding tools for processing plastics.     In convention tempering processes, it is not possible to adapt the temperature conditions to the instantaneous process parameters, and both quantities of interference in the injection molding process and the unfavorable position of cooling surfaces relative to the tool contour of complicated tools cannot be compensated.     As a solution, it is proposed that the tempering process is divided in two phases, a start-up phase and a stationary operating phase, each having different tempering conditions, whereby the start-up phase is completed after the preset nominal tool temperature has been reached or exceeded for the first time, and the meantool temperature is continuously measured during the entire cycle duration at a precisely defined site, and whereby at time Z2, the latter being fixed by a signal of the machine sequence control, a cooling medium impulse, the latter taking into account the tempering in the preceding cycles; is induced close in time to the injection process in order to effect the required heat dissipation within the time range of the greatest temperature difference between the injected melt and the cooling duct, and further cooling medium impulses are induced as the result of a should be-actual comparison occurring at time Z2 if the preset nominal temperature is exceeded, whereby the time Z2 is fixed by a signal of the machine sequence control, such signal being triggered at a defined time close in time to the end of the cycle.     The invention is preferably applied in the tempering of injection molding tools and leads to cycle time reductions of about 5 to 15%, a reduction of the reject quota by up to 35%, and to a reduction of the specific energy consumption by about 10 to 20%.

In this configuration, a second planar structure is pivotally attached to the top edge of the first structure to prevent snagging, and to enable the user to manually deflect both latches simultaneously. In another configuration, a pair of clips are used to join the simplex connectors together, one on top of the other, to form a vertically stacked duplex connector. In this configuration, the anti-snag feature is provided by cantilever triggers that are mounted on each simplex connector adjacent to the latches.

Title: High load-carrying turbo oils containing amine phosphate and a sulfur containing carboxylic acid
Inventor: BELTZER MORTON
IPC: C10M141/10
Filed: 1996-11-07
Abstract: This invention relates to synthetic based turbo oils, preferably polyol ester-based turbo oils which exhibit exceptional load-carrying capacity by use of a synergistic combination of sulfur (S)-based and phosphorous (P)-based load additives The S-containing additive of the present invention is sulfur containing carboxylic acid (SCCA), preferably the C1-C4 thioether carboxylic acid and the P-containing component is one or more amine phosphates.  The turbo oil composition consisting of the dual P/S additives of the present inven-tion achieves an excellent load-carrying capacity, which is better than that obtained when each additive was used alone at a comparable treat rate to the total combination additive treat rate, and this lower concentration requirement of each additive allows the turbo oil composition to meet or exceed US Navy MIL-L-23699 requirements including Oxidation and Corrosion Stability and Si seal compatibility.
