A transaction card allows for retail purchases involving fractional dollar amounts to be completed without the use of coin currency. Change amounts involving less than one dollar can be either credited to or debited from a monetary value stored on a smart chip in the transaction card by placing the transaction card into a card reader that reads a magnetic swipe strip associated with the smart chip. Amounts credited to the transaction card can be used for secondary transactions not involving pape...

A cycle gear change enabling the cycle drive chain to pass from one free wheel pinion to another, these pinions having a relatively large difference in the number of teeth in order to obtain a large speed variation for the moving cycle, this gear change being fitted with a roller which may be displaced cross-wise to a cycle free wheel so as to ensure cross-wise displacement of the chain and its passage from one free wheel pinion to the other, and a second roller articulated in relation to the fi...

In the tool change device, a tool change arm 27 for changing a tool 25 with respect to a main spindle 24, a main tool magazine 29 including a plurality of hold grooves 30 arranged linearly for holding the tools 25, and a tool storage member 41 including at least one storage portion 46 for storing the tool 25 are arranged in the back-and-forth direction of the tool change device. In order that the tools 25 can be delivered between the tool change arm 27 and main tool magazine 29, between the main...

A speed change control method of controlling a speed change ratio of a continuously variable transmission mechanism including a traction continuously variable transmission, includes: estimating a tilt angle of a power roller included in the continuously variable transmission based on an input rotating speed and an output rotating speed of the continuously-variable transmission mechanism; estimating a position of the power roller based on an estimated tilt angle obtained by the tilt angle estimat...

A speed change gear system for providing at least four forward drive speed ranges and one reverse drive speed range includes planetary gear sets of the single-pinion type and simple planetary gear sets of the double-pinion type as well as a plurality of clutches and brakes. As a result of the coupling and uncoupling of the clutches and brakes, the movable elements of the gear sets are suitably coupled so as to attain the various speed ranges.

In an automatic tool change apparatus, numbers of tools stored in respective tool holding devices mounted on a magazine and held in a spindle are identifiable whether the tools are large or small ones. A combination of a tool held in the spindle and a tool commanded by NC data is discriminated to selectively perform a normal or special cycle of a tool change operation.

This invention provides a color change perfume system in which color is caused to change when the perfume in the system is effectively exhausted to the atmosphere. The invention also provides air fresheners and the like consisting of a porous carrier impregnated with the perfumed color change system.

Change-speed transmission providing multiple forward speeds and at least one reverse speed. An output shaft of the transmission carries a first speed pinion or gear that is rigid with a hollow shaft that carries, in turn, a gear or pinion of the reverse gear train disposed upstream of other forward speed gears or pinions. The reverse gear carries a dog that is separated from a dog carried by the closest forward speed gear by a dog and synchromesh unit. A layshaft mechanism is positioned parallel...

Optical projection apparatus utilizing a pulley and cable mechanism for positioning optical components thereof which comprises a fixed pulley means, translatable pulley means and cable means entrained about the foregoing means. A clutch is provided to selectively preclude rotational movement of the fixed pulley means while translational movement is imparted to the translatable pulley means to thereby effect repositioning of the translatable pulley means relative to the fixed pulley means. An opt...

A travelling block system that can be changed quickly from a four support line system to a two support line system, which comprises a travelling block having two sheaves, and a single sheave block with hook, attached to the crown of a boom. The two sheave travelling blocks comprise a frame with two parallel spaced plates serving as inner sheave plates, two sheaves on the outside of the inner sheave plates, and two outer sheave plates. The sheave plates are firmly bolted to the frame, and appropr...
