Abstract: A fuel-water separator comprises a container having entry and exit ports and a progression of spaces through which the fuel moves. The spaces become progressively smaller and are arranged to direct the fuel through a series of downwardly and upwardly directed paths. The lower density fuel moves upwardly while the higher density water tends to move downwardly to drain through drainage openings provided in the lower portions of the spaces. Valves are provided for closing the drainage openings. The valves include float-valve balls which will release the water but hold the fuel. One of the spaces in the container includes a media having a downwardly directed surface upon which the water coalesces to move downwardly and through which the fuel moves to progress to the next space. Another one of the spaces includes a media providing a surface tension-discriminating surface through which the fuel will move and down which the separated water will move.

Abstract: A vehicular mounted pipe presser includes a pipe-pressing assembly for pressing pipe through a medium wherein the assembly is movably supported by a vehicle and positionable between surfaces which are transverse to the direction of forces employed to press the pipe. The assembly includes a frame having projectable and retractable feet for engaging the transverse surfaces to stabilize the assembly. Movably carried by the frame is a housing for receiving the pipe and a clamping mechanism which floats with the housing for clamping a portion of the pipe. Two clamp jaws of the clamping mechanism are captured within the housing and pressing forces are limited to the housing and the clamp jaws. The projection and retraction of the feet, reciprocable movement of the housing, and clamping of the pipe within the housing are each separately controllable from a stage carried on the housing by hydraulic systems.
Abstract: A method and apparatus for controlling the rate of operation of a glassware forming system including a temperature sensing device positioned in the blank and blow molds of an I.S. machine. The mean temperature over a period of time is derived for each of the molds. The mean temperature is compared to a predetermined optimum temperature. The optimum temperature is chosen to be the highest desirable temperature at which the corresponding molds should operate. In response to the comparison of the detected and optimum temperatures, the speed of the I.S. machine is varied to increase or decrease machine speed depending upon which the mean mold temperature is, greater than or less than the optimum temperature, respectively. However, before the speed is changed, if the detected and mean mold temperatures are greater than the optimum temperature, the amount of cooling air is increased until it reaches a maximum.

Abstract: A pipe or armature connection includes two interfitting connecting members. The connecting members include surfaces providing axial and radial guidance upon their assembly but require only a small space for assembly and disassembly. One of the connecting members includes a groove dimensioned to positively retain an O-ring sealing member placed therein so that it will not fall from the groove. The dimensions of the groove and the one connecting member are such that the bulging portion of the O-ring is protected from damage by the extended surface of the one connecting member. Upon assembly of the two connecting members, the O-ring is urged into the space between the two members, thereby precluding the collection of materials in the space and rendering the connection more easily cleaned. This system is particularly advantageous in pipe systems that carry food products and materials that must be hygienically cleaned after use.
