A disposable phase change device for sensing the rate of cooling of molten metal includes a body having a shallow elongated cavity on its upper surface. Sensing means extend across the cavity and is supported by first and second oppositely disposed walls on the body. The sensing means includes contacts adjacent opposite ends of the body. The upper surface of the body has one or more overflow cavities.

A machine for dispensing coinage change including a conveyor in the form of a belt or plate and including rows of coin receiving apertures or recesses with a mechanism to advance the conveyor means forward in response to a manually operated coin actuated drive mechanism, with the conveyor being advanced beneath a plurality of supply tubes adapted for alignment with corresponding rows of apertures or recesses in the conveyor and extending in the direction of motion of the conveyor. Coinage change...

A nutation drive apparatus wherein the nutator is prevented from rotating or is allowed to undergo controlled rotation in one direction during operation of the apparatus by means of simultaneous nutative contact with two rotors or stators or by restraining means acting on the central plane of nutation of the nutator. The nutator may make contact with the rotor(s) or stator(s) by means of friction-drive surfaces and the position of the centre of nutation which remains stationary during nutation m...

A device for measuring the phase change of an input signal over a specified eriod comprising a phase-locked tracking filter including a high frequency voltage-controlled oscillator (VCO), a frequency divider to give local oscillator signal at the same frequency as the input signal and a counter counting cycles of the VCO whose phase change in any period is N times the input phase change to allow 1/N period resolution, N being an arbitrary integer. The phase change measuring circuit thus allows p...

A vibrator-ribbon guide connecting structure is provided for facilitating coupling thereto of a ribbon guide through which a ribbon is prethreaded whereby quick and clean ribbon changing may be accomplished. The ribbon guide and vibrator are so associated that the ribbon guide is freely removable from the vibrator when the vibrator is at rest yet is positioned to be elevated and positively retracted by the vibrator during vibrator movement.

An improved electrical field change meter comprising the improvement of a pacitor being provided that may be used during severe weather conditions such as rainstorms wherein the dielectric constant between the plates, air, is not affected by severe conditions. This is obtained by providing hemispheric shaped condenser plates, one mounted inside the other, and spaced therefrom by insulating standoffs. The entire condenser assembly is sealed to its based member to provide a weatherproof container ...

Speed change gears of the planetary gear type suited for applications within fluid couplings used upon automotive vehicles includes an input shaft, a first clutch for releasing or coupling a second ring gear and a third sun gear simultaneously from or to the input shaft, a second clutch for releasing or coupling a first sun gear and a second sun gear simultaneously from or to the input shaft, a first planetary gear engaged with the first sun gear, a first ring gear engaging the first planetary g...

A five speed epicyclic change speed hub has two epicyclic gear trains utilizing a common planet cage and having an axially adjustable gear ring which is adapted selectively to control various uni-directional clutch means connecting the two gear rings with the hub shell between operative and inoperative conditions according to its position axially of the hub and to the combinations of operative and inoperative uni-directional clutch means appropriate to requisite drive transmission paths.

A device is provided for indicating the occurrence of rate of change of velocity of a body equal to or in excess of a predetermined value. An inertial mass is yieldably biased toward a reference position, but moves to a second position when the body is subjected to rates of change of velocity in excess of the predetermined value. A light source is provided, and when the inertial mass is in its reference position, a first light responsive means is out of light communication with the source, while...

A quick-change chuck is disclosed which holds a tool socket having an adjustable nut thereon for axial adjustment of a tool within the tubular wall of a spindle. The quick-change chuck includes a locking sleeve secured to the spindle and a control sleeve which reciprocates on the locking sleeve. A plurality of collet fingers are carried in the locking sleeve, and each has a tapered foot to engage the outermost beveled shoulder of the adjusting nut. A tapered annular shoulder on the locking sleev...
