Patent CA-2065826-A1 (CA)
Title: Blow molding extrusion head
Inventor: THRONE JAMES L
IPC: B29C48/475
Filed: 1992-04-10
Abstract: An extrusion head for a blow molding machine wherein a movable plunger is slidably mounted in a distributor head which receives a melt at an inlet end of its channel and directs it along such channel to the terminal end of the channel while simultaneously directing portions of it along spiral radial paths to the lower circumferential edge of the distributor head to fill an accumulator chamber which also causes the plunger to recede facilitating the filling of the accumulator chamber. The channel as defined by the adjacent circumferential wall and the curvilinear contour on the distributor head defines a smooth integral flow channel that is curvilinear in cross section.

Title: Injection Molding Nozzle with Removable Forward Member
Inventor: GELLERT JOBST U
IPC: B29C45/20
Filed: 1992-07-13
Abstract: A heated injection molding nozzle having a rear member and a forward member which is removable. A channel extends through the rear and forward members to convey pressurized melt to one or more gates extending through the mold to a cavity. The rear member has an electrical heating element with a spiral portion which extends around the melt channel. The forward member has a tapered rear portion which extends rearwardly into a matching tapered well in the rear member. The taper is sufficient so the tapered portion is frictionally retained in the well to removably mount the forward member to the rear member This allows the forward member to be easily turned or driven out of engagement in the well to replace it with a new forward member or a forward member having a different configuration to provide a different type or arrangement of gating.

Title: System and method for treating sewage or other fluids
Inventor: VANDERVELDE DONALD M
IPC: B01D24/00
Filed: 1991-01-14
Abstract: This invention lies in the field of on-site sewage and wastewater treatment.  Standard on-site septic systems require special soil and groundwater conditions with large lot sizes. This invention comprises a method and device for complete treatment of sep-tic tank effluent or other contaminated water by contriving for it to flow in an ultra-thin film over a surface treatment medium such as fabric or sand, providing diffusive aeration, biological reaction, and physical filtration on a molecular scale. The device transfers contaminated water from a container (48) to a final collector (42), completely purifying the liquid in the process. The pu-rified effluent can then be reused for household, industrial, irrigation or other uses, or disposed of as normal surface run-off in streams or lakes. To increase efficiency, said container encloses a progressively more finely pored media (18, 22, 26, 28, 32) pre-cisely situated with effluent seeping gradually through progressively finer pores to provide effective pretreatment.

Patent CA-2079696-A1 (CA)
Inventor: TANAKA YOSHIHIRO
IPC: G01R31/3185
Filed: 1992-10-02
Abstract: A logic function block having an output signal potential sensing function is substituted for each of logic function blocks of which fault conditions cannot be detected on the basis of predetermined input/output signal combinations for determining whether or not the semiconductor integrated circuit device operates correctly.  Probe lines and sense lines are connected only to the logic function blocks having output signal potential sensing function.  The probe lines are driven from a probe line driver, and a sense line receiver reads out signals on the sense lines.  Thus, without reducing fault detecting efficiency, the areas of an active region and a wiring region required for forming a fault detecting arrangement can be reduced.

Title: Multiplex transmission method and a synchronizing method in multiplex transmission
Inventor: HARA TOSHITAKA
IPC: H04L12/413
Filed: 1992-10-14
Abstract: ABSTRACT OF THE DISCLOSURE     When a message is transmitted, frame by frame, from any one (10) of a plurality of multiplex nodes to a common multiplex bus (MB) to which the multiplex nodes are connected, each of the multiplex nodes (20 and 30) determines that transmission of a frame therefrom is allowed when it detects a transmission permission signal (b, b') added to the frame after detection of and idle state of the multiplex bus, and starts transmitting a message frame.  This makes it possible to properly implement priority-based control according to the priority levels of the frames irrespectively of variations in the reference clocks of the multiplex nodes.  Further, receiving multiplex nodes perform frame synchronization at the rise of a special code (a) of a start code (SOM) of a message frame, then perform re-synchronization at the rise of a special bit pattern (b") which consists of a passive bit and a dominant bit.  This prevents synchronization from being deviated and bit errors resulting from deviated synchronization, thus leading to higher reliability of multiplex transmission.

Inventor: JESKEY MARION M
IPC: G02B5/08
Filed: 1991-04-24
Abstract: Mirrors are formed in an environmentally compatible and substantially pollution-free manner by a sputtering process in which a transparent substrate (10) such as glass has first sputtered upon it a primer layer (12) and then a reflective layer (14) of silver or other bright reflective metal. A barrier layer (16) is provided over the reflective layer (14) to protect the latter from corrosive environments. If the transmittance of the reflective layer (14) is greater than zero percent, the barrier layer (16) includes a different bright reflective metal sufficient to reduce the transmittance of the combined reflective and barrier layers to zero percent. The mirror includes a lead-free polymeric protective layer (22) spaced further from the transparent substrate than the barrier layer. The inclusion of zinc pigment in the polymeric coating (26) provides sulfiding protection, and the use of an outer sputtered on film of zinc (24) or zinc oxide (24) provides substantial adhesion thereto of the polymeric coating (26).

Title: Low power noise rejecting ttl to cmos input buffer
Inventor: WANLASS FRANK M
IPC: H03K19/003
Filed: 1993-02-12
Abstract: A low power, noise rejecting TTL-to-CMOS input buffer, without the use of a current consuming voltage reference, has the characteristic of recognizing a logic LOW as less than 0.8 volts and a logic HIGH as greater than 2.0 volts for DC TTL signals while drawing only leakage current from its Vcc power supply, and simultaneously possesses the characteristic of rejecting high-amplitude Vin noise. For an input signal rapidly rising from zero to three volts, the buffer output switches at an input signal level of approximately 2.5 volts; and for the input signal rapidly falling from 3 to zero volts, the buffer output switches at an input signal level of approximately 1.4 volts.
