Abstract: The present invention is directed to an ink supply device having an ink cartridge and a cartridge mount. The ink cartridge has an ink supply portion and an air intake portion. The cartridge mount has a first projection and a second projection. When the ink cartridge is inserted into the cartridge mount, the first projection opens the ink supply portion, and the second projection opens the air intake portion. The second projection has an operating piece, a guide path for receiving the operating piece, and a spring for exerting force on the operating piece. The second projection contacts the air supply portion prior to the first projection contacting the ink supply portion, and the guide path receives the operating piece after the second projection contacts the air supply portion.

Abstract: An inflator (20) comprising: a pressure vessel (22) made of a thin walled steel tubing (24), sealed at one end by an end plate or cap (30). The other end of the pressure vessel sealed by a propellant housing (50). A plurality of axial bores (56a-d) exiting through an adjacent part (58) of the housing (50) and a face of the adjacent part of the housing includes a second counter bore (70) and a plurality of radial bores (72a-d) radially extend therefrom. A rupture disk assembly (100) having a central portion (102) forms a rupture disk extending into the second counter bore (70) and a radially extending outer portion (104) fitted generally flat against the face (60) .

Abstract: A method for zero-resetting of a device for measuring transmitted torque while a cycle is in motion consists in monitoring a phenomenon or a parameter which is normally variable during normal use of the cycle and which disappears or becomes constant when the driving wheel rotates on free-wheel motion. When the disappearance or the constant character of the phenomenon or parameter thus monitored is observed during a predetermined period of time, one initiates zero-resetting of the detector system or of the measuring system proper of the torque-measuring device. The device for carrying out the method includes on the one hand a monitor for the phenomenon or parameter and on the other hand a control which are operated in dependence on the signal emitted by the monitor and which are then capable of producing action on the detection system or the measuring system in order to reset either of these two systems to zero.

Abstract: An electronic reset circuit is provided for a fluid dispenser of the type including a fluid pump and a meter, wherein upon deactivation of the fluid pump, the meter must be reset in order to reactivate the pump and a resetting device normally actuatable for accomplishing meter resetting. The electronic reset circuit comprises a reset control switch actuatable only by a fluid dispenser attendant and an electronic circuit coupled with the resetting device and with the reset control switch for preventing resetting of the meter in response to normal actuation of the resetting device until actuation of the reset control switch by the attendant.

Abstract: The connection between the actuating handle of a gasoline service station pump and the pump shaft is a lost motion connection wherein the pump may be actuated in the usual manner for turning the gasoline pump on but in returning the actuation handle to the vertical position, the connection between the handle and the pump shaft is floppy, i.e. a lost motion connection, so that the dial setting of the pump cannot be altered but the attendant can reset the indicating dials to zero and release the actuation lever for further operation by holding the actuating lever stationary, inserting a tool into the pump operating shaft and rotating the shaft and sleeve counter-clockwise a specified amount.
