摘要： An adapter having a body portion with a bore for slideably receiving a valve-operating projecting rod on a plunger and also having a counterbore for receiving the head of the plunger. A seat is formed in the body portion, and the plunger is selectively engageable with such seat when an operating pressure exists in the system such that the rod upon seating of the plunger has moved the diaphragm-type valve to an operative position. Through the arrangement of seating of the plunger in the body portion and predetermined length of the rod the plunger exerts the same operating pressure on the diaphragm-type valve regardless of the pressure to which the plunger is subjected. The housing has an inlet opening leading to the counterbore for the entrance of plunger-operating fluid, and such opening has fluid inlet-restricting means therein for feeding fluid under pressure to the plunger at a slow rate to prevent shock operation of said plunger.

摘要： Exercise apparatus such as a treadmill, rowing machine, pedaling device or the like which includes an indicator arranged to be driven at a rate in proportion to the degree of difficulty of the exercise expended for recording work done. The apparatus in its embodiment employs an operating member on which the person exercises and adjustable controls for varying the difficulty of the exercise. The indicator is driven by the operating member through a drive connection, and the apparatus includes adjustment means incorporated in the drive connection which is connected directly to the adjustable controls so that the rate of operation of the indicator is in proportion to the degree of difficulty of the exercise.
摘要翻译：锻炼装置如跑步机，划船机，踏板装置等，其中包括一个指示器，该指示器以与用于记录所完成的工作所花费的运动的难度成正比的比例驱动。在其实施例中的装置采用操作构件，人们在其上进行锻炼和可调整的控制，以改变运动的难度。指示器通过驱动连接由操作构件驱动，并且该装置包括并入到驱动连接中的调节装置，该调节装置直接连接到可调节控制器上，使得指示器的操作速度与难度的比例成比例演习。

摘要： The system of the invention is designed for treating liquid which may comprise as one instance means for cooling liquid. Such is accomplished by a novel cooling tank. The system has particular application in Diesel engines and also may be used as cooling systems for the liquid used in cooling machine tools. The system may include a meter arranged to measure consumption of fuel, particularly in the Diesel system. Where the system is used with Diesel engines and a meter is used, a by-pass is provided around the meter which includes a valve so that the by-pass can be used when it is desired that the flow be not measured.

摘要： A FRAME HAS A PAIR OF END DRUMS OVER WHICH OPERATES AN ENDLESS BELT. ONE OF THE DRUMS IS DRIVEN BY A VARIABLE SPEED ELECTRIC MOTOR TO CAUSE TRAVELING MOVEMENT OF THE BELT WHEREBY A PERSON CAN EXERCISE BY RUNNING ON THE BELT. AN ODOMETER IS CONNECTED INTO THE DRIVE SYSTEM TO MEASURE THE DISTANCE TRAVELED BY THE BELT. THE ODOMETER HAS A DISTANCE INDICATING DIAL, PREFERABLY MILES AND FRACTIONS THEREOF, AND OPERATES A SWITCH IN THE CIRCUIT TO THE DRIVE MOTOR TO CONTROL OPERATION OF THE MOTOR. ALSO PROVIDED ARE VARIABLE SPEED CONTROL MEANS FOR THE MOTOR AND ALSO A TIME INDICATOR, THE SPEED CONTROL MEANS OPERATING A SWITCH IN THE CIRCUIT TO THE DRIVE MOTOR AND ARRANGED TO CONTROL OFF AND ON OPERATION OF THE MOTOR. A HAND RAIL IS PROVIDED ON THE FRAME, AND A HOUSING IS MOUNTED ON THE HANDRAIL FOR SUPPORTING THE ODOMETER, SPEED CONTROL MEANS AND TIME INDICATOR IN A CONVENIENTLY ACCESSIBLE AND VIEWABLE POSITION. THE BELT HAS A ROUGHENED SURFACE FOR CONDITIONING THE FEET. THE FRAME AND BELT HAVE A DISCONNECTABLE JOINT ALLOWING THEM TO BE FOLDED INTO A COMPACT PACKAGE FOR SHIPMENT AND STORAGE.
