A change return control for a money handler in a vendor capable of a plurality of customer selectable transactions at different prices, the money handler having circuitry for identifying the denominations of money deposited in the vendor. The control includes circuitry for determining if a coin storage means in the money handler contains first and second predetermined amounts of change, and a vend control for permitting a vend. Logic circuitry determines the amount of credit accumulated as a res...

A hybrid straight and curved guide phase change coupling device in which end members rotatable on spaced parallel axes in opposed spaced relation are connected by an intermediate member having guide means constraining lateral motion of the intermediate member to a straight diametrical path with respect to one of the end members and to a curved path with respect to the other of the end members whereby a cyclic phase change or velocity ratio variation is provided during rotation of the two end mem...

A change speed transmission device using gears employs a shift drum mounted parallel to the driving and driven shafts. The shift drum is turned one-quarter revolution at a time to cause a shifting mechanism to produce a low speed drive, and an intermediate speed drive, and a high speed drive between the shafts, and then back to neutral. A pivoted pawl engages an abutment on the shaft drum to limit turning movement of the drum. An element frictionally engages a member fixed to rotate with the dri...

A means for coding and decoding video signals by the application of one of a plurality of available scrambling signals, which scrambling signals have a common frequency but differ in phase, includes means for comparing the brightness level during a predetermined time period of the video signal with the brightness level of the video signal over the succeeding predetermined time period. There are means for changing from one scrambling signal to another if the difference between brightness levels i...

A diaphragm-type transducer assembly is mounted on the rear of an automobile to transmit ultrasound into left- and right-hand target regions near the automobile. Spoilers are mounted adjacent to the transducer diaphragms to disrupt the air flow around them and prevent negative pressure that could adversely affect the operation of the transducer. The circuitry for driving the transducers includes relays in the signal-lamp circuit to detect when the turn signal is turned on, and it only transmits ...

An electrical connector having a series of terminals having contact portions located at different pitches at different faces of the connector. The terminals are formed from identical blanks and have looped body portions integrally joining the contact portions which body portions are deformable both laterally to accommodate the pitch-change and longitudinally to enable the contact portions to lie in coplanar places at respective faces.

A change-speed apparatus for a tractor for transmitting engine power to running travel apparatuses via a main change-speed mechanism, an auxiliary change-speed mechanism and a forward-and-rearward-travel-shifter mechanism. These mechanisms are arranged in series in fore-and-aft direction of a machine body and a shifter lever for the said forward-and-rearward-travel-shifter mechanism is disposed in juxtaposition to a main change-speed lever for the said main change-speed mechansim.

A change making system having circuitry for sensing the availability of coins for making change in at least two change tubes containing coins of different denominations, the coin tubes being part of a money handler in a vendor. A memory has stored therein, for each of a number of coin availabilities, a plurality of coin combinations equalling various amounts of change. A microprocessor determines the amount of change due the customer and retrieves from memory a coin combination, if any, stored t...

An oil change kit apparatus includes a cylindrically-shaped pan that supports a bracket at its upper annular surface. The bracket has a threaded bushing that receives an externally threaded stem of a funnel, the stem having a hollow open ended flow bore. The funnel adjusts in elevation relative to an underlying support surface, floor, etc. by rotation of the funnel relative to the bracket.

A spark plug quick release system is provided including a spark plug with an annular detent formed therein. An adapter is provided with a hollow cylindrical configuration having a lower end with a plurality of threaded grooves formed in an outer surface thereof for screwably coupling with a spark plug threaded mount. Next provided is a quick release assembly including a sliding tube slidably situated about an outer surface of the adapter. By this structure, the sliding tube has a lowered orienta...
