An injection molding system configured to operate in a plurality of cycles includes, amongst other things, a controller that is configured for performing a comparison of a variable pressure setpoint with a target pressure value. The controller is configured to, when the target pressure value is less than the variable pressure setpoint by at least a predetermined lower bound, (i) decrease the variable pressure setpoint to a reduced variable pressure setpoint and (ii) not further decrease the variable pressure setpoint from the reduced variable pressure setpoint until the pump assembly operates for a plurality of stabilizing cycles at the reduced variable pressure setpoint.

In one aspect, there is provided an injection molding system configured to operate in a plurality of cycles. The system comprises, amongst other things, a controller that is configured for performing a comparison of a variable pressure setpoint with a target pressure value. The controller is configured to, when the target pressure value is less than the variable pressure setpoint by at least a predetermined lower bound, (i) decrease the variable pressure setpoint to a reduced variable pressure setpoint and (ii) not further decrease the variable pressure setpoint from the reduced variable pressure setpoint until the pump assembly operates for a plurality of stabilizing cycles at the reduced variable pressure setpoint.

Disclosed is a hydraulic system for a molding system, the molding system having a clamp actuator and an injection actuator, the hydraulic system comprising a clamp accumulator for storing hydraulic fluid for use in actuating the clamp actuator; an injection accumulator for storing hydraulic fluid for use in actuating the injection actuator; a pump for conveying hydraulic fluid to the clamp accumulator and the injection accumulator; and a selector valve for selectively fluidly connecting the pump to one of the clamp accumulator and the injection accumulator.

A tool is used to custom fit rubber slip-ons onto golf shoes for use in wet conditions to keep the feet of the golfer dry. The tool can be manually manipulated to cut openings into the sole of a slip-on of an appropriate size so that the openings are aligned with the spikes of the golf shoe. When openings have been cut for all of the spikes, the sole of the slip-on rests against a base of the spikes and the sole of the golf shoe. The tool has an elongated hollow body with two ends. One end has a circular cutting edge thereon and the other end has a handle thereon. After the slip-on is placed onto the golf shoe with the spikes separating the sole of the slip-on from the sole of the golf shoe, the tool is aligned with each spike in turn to cut an appropriate opening for that spike. Previously, slip-ons have been designed with pre-cut openings but these slip-ons can only be used with a specific model of golf shoe of a specific manufacturer having a specific size.

A holder for storing compact discs where each disc is contained within a conventional disc container uses a housing and anchoring means for the housing. The anchoring means is used to mount the housing in a motor vehicle. The housing contains partial partitions that are sufficiently large to hold said containers in a spaced apart parallel relationship from one another extending from front to rear of said housing when the disc containers are inserted into the housing through the front. The housing has retention means for each container to hold the containers within the housing when the containers are oriented with the groove towards the rear wall and towards the retention means. The retention means contacts a groove of each disc container and holds said container in said housing until the container is pulled out of said housing so that the retention means automatically releases itself from said disc container. When the holder is used in a motor vehicle, when desired, the housing can easily be removed from the anchoring means and removed from the vehicle. Alternatively, the housing could be removed from the anchoring means but stored in the trunk or glove box of the vehicle.
