Abstract: The device consists of a slider (2) operating in a sliding manner with respect to a ruler (1). Slider (2) is fitted with emitting electrodes (10) and receiving electrodes (19,20) connected to an electronic assembly (50). Ruler (1) is provided with L and inverted L-shaped coupling electrodes (6,7) which interlock mutually to form electrode-pairs which position is limited by straight lines. The vertical parts of the L's (40) are arranged to face emitting electrodes (10), whereas the horizontal parts of the L's (41) are arranged to face the receiving electrodes (19,20), providing an optimal capacitative coupling. This arrangement of the coupling electrodes (6,7) makes it possible to obtain a precision type manufacture of the ruler and a side by side (juxtaposition) arrangement of several rulers to fit the measuring needs.

Each of the top walls include a threaded neck opening to which are attached sealing cap members. A carrying handle is attached to one top wall and the remaining top and bottom walls have finger notches to facilitate grasping of the container. The container can rest on either bottom wall and can be filled from the opening in the opposing top wall or emptied from the opening in the adjacent top wall.

Abstract: An improved tape dispenser includes a housing having parallel spaced sidewalls which have lower edges defining a housing base. The sidewalls may be joined at the top, front and rear of the dispenser but remain open at the lower edges. A resilient tongue extends between a forward portion of the sidewalls and has a portion which protrudes below the lower edges. The protruding end portion has a straight, radiused end for smoothly engaging and applying the tape. A cutting blade is disposed slightly forward and above the end portion of the tongue. Tabs on a rearward surface of the tongue form a guiding slot for the tape and prevent the leading edge from being retracted into the dispenser. Upon drawing the dispenser rearwardly with the lower edges parallel to the surface, the resilience of the tongue causes the radiused end portion to press the tape down to the surface.

In the preferred form of the invention, the centrifugal impeller and an electrical generator are rotatably driven at a constant speed and in synchronism with each other and, together, form an electrical and pneumatic power system.

Abstract: The present invention provides a bearing assembly for use in a display assembly having a plurality of louvers which rotate in synchronism with each other and, in doing, displays different advertising messages. The bearing assembly includes a housing having an axis and a shaft extending axially through the housing. A pair of axially spaced bearings rotatably mount the shaft to the housing. A pair of collars are secured to the shaft so that the bearings are contained in between the collars while a Belleville washer is sandwiched between one collar and one bearing and exerts a compressive force on the bearings and a tension force on the shaft in order to compensate for bearing wear and manufacturing tolerances. A novel construction for mounting the louvers in their frame is also disclosed.

Abstract: A power unit of the type varying its length comprises three members movable in relation to each other. The power unit is used for transferring load from a first load carrier to a second one. In order to make this transfer possible in a satisfying manner, the power unit has to be constructed so that it can be extended to at least two times its length in the contracted state. For this reason it is a necessity that transmissions comprising wheels (13) and a loop (15) laid around these are so arranged, that when the third member (3) is displaced with respect to the first member (1) fixed in the room, at the same time the second member (2) is displaced in the same direction and the same distance with respect to the third member (3). In order to solve this problem in an appropriate manner the invention proposes to design the first member (1) with at least partly the character of a housing for the power unit, with an elongated shape in cross section.

Abstract: A method and apparatus for automatically rethreading the electrode wire of a traveling wire EDM apparatus through a pair of close tolerance wire support and guide members, one disposed on one side of a workpiece and the other on the other side of the workpiece, and for threading the end of the wire through a starting aperture in the workpiece. Prior to threading or rethreading the wire, the wire is heated in a heating zone while a pull is exerted on the wire such as to elongate the heated portion of the wire to reduce its diameter. After cutting off the wire at the beginning of its reduced diameter portion, the reduced diameter portion of the wire is threaded through the wire guide members and the aperture in the workpiece. The threading of the wire is effected by a feed mechanism disposed upstream of the first wire guide member which preferably is the same mechanism as the brake mechanism effecting a pull on the wire during normal operation of the EDM apparatus.

Abstract: An improved muffler system for internal combustion engines recovers heat energy of exhaust gases by spraying a fluid into the exhaust stream in order to absorb the heat energy of the exhaust gases. The heated fluid is collected at the bottom of the muffler vessel and the stored heat energy is transferred to a second fluid via a counter-current liquid to liquid heat exchanger. The heat energy from the second fluid is then removed and utilized, for example, to condition passenger spaces.
