Abstract: A control system controls a second to third gear shift of an automatic transmission in an advantageous way. The transmission has a 3-4 clutch, which is locked under hydraulic pressure, and a 2-3 brake provided with a lock pressure chamber and an unlock pressure chamber. The 2-3 brake is locked when a hydraulic pressure is developed in the lock pressure chamber only and is unlocked when a fluid pressure is developed in the unlock pressure chamber and when a hydraulic pressure is released from both the lock pressure chamber and the unlock pressure chamber. Hydraulic pressure is released from the lock pressure chamber so as to unlock the 2-4 brake only when a second to third gear shift is needed for the first time after engine ignition simultaneously with application of pressure to the 3-4 clutch so as to lock the 3-4 clutch.

A curved handle disposed upon the carriage enables the same to be moved, thus slicing the food, with one palm bearing thereagainst.

Abstract: A vibrato arm mounted on a floating bridge of a string instrument is adapted to engage an anchor seat attached to the body of the instrument, in order to lock the bridge in its centered position when the vibrato arm is parked. When the arm is moved to the play position, a cam arrangement raises the arm out of the anchor seat and frees the bridge for vibrato movement. A single adjustment of the riser on the vibrato arm selects both the desired park position and the vertical engagement position of the arm. The seat-engaging arm end and the seat itself are tapered to guide the arm into centered position. The anchor seat is eccentrically and linearly adjustable for precise centering of the bridge.

Abstract: A power-driven voicing tool simultaneously inserts into and withdraws from the felt of a piano hammer, needles to raise a nap thereon. A row of four needles is driven by two circularly moved cam surfaces on the ends of an assembly rotatable by a variable speed electric motor through a flexible drive cable. One cam surface lies outside the other and drives the external needles of the row of needles; the other drives the internal needles. The slopes of the two cam surfaces are different and one-hundred-and eighty degrees out-of-phase with each other and effect different movements in adjacent needles, one needle moving outward while the other moves inward. A process of inserting a needle while withdrawing an adjacent needle in the felt of the piano hammer, is practiced.

Abstract: A cylinder apparatus capable of effectively restraining a loss of energy with a simple structure at a low cost. When a piston 16 of a main cylinder 11 cuts off a communication between a subchamber 20 and a supply/exhaust passage 32, a pressure of the subchamber 20 is pushed by the piston 16 and thereby increased. However, an exhaust fluid from the subchamber 20 having the increased pressure is fed to a subcylinder 62. A piston 48 is moved while controlling a velocity by a flow rate control valve 70 in synchronization with the piston 16. This arrangement eliminates a necessity for a special position detector, etc.. The structure is therefore simplified, and the cost decreases. Simultaneously, the energy can be effectively utilized because of employing the exhaust fluid.

Abstract: A method of applying printing ink to cylindrical objects includes coating the external surfaces of cylindrical objects with migration-preventing plastic material which has an affinity for ink, and advancing the coated objects continuously, in series, one after the other, through an ink application zone wherein printing inks are transferred from a flexible carrier onto the coated surfaces of the objects.

At least the carrier is heated above the sublimation temperature of the printing ink, and a temperature gradient is established in the plastic coats from the inside to the outside prior to, or not later than upon, entry of objects into the ink application zone. To this end, the ink application zone immediately adjoints a production line for the objects.

Abstract: A process for reducing sulfur emissions and increasing particulate removal in the combustion of pulverized coal is presented. Pulverized sulfur-containing coal is injected along with combustion air into a combustion chamber and fired to create a combustion zone within the chamber, thereby creating gaseous sulfur and particulate emission products. The emission products are directed to an exhaust means where the particulate emission products are removed. A fuel having negligible sulfur content and a heating value higher than coal is injected in substantially the same direction as the coal and combustion air stream into a region of the combustion zone through which a majority of the of the gaseous sulfur emissions must pass to reach the exhaust means, thus increasing the temperature of the region in an amount sufficient to increase the sulfur content of the particulate emission products.

In case of ecological preparation of consumption goods such as motor vehicle wrecks or the like, a large-volume apportioning of the scrap goods is carried out by subdividing and/or crushing prior to the intermittent feeding into the pyrolysis chamber.

Abstract: In a trimming sewing machine a chain (16) is formed on a workpiece (5) at the end of a stitching, which chain must be then cut and reversed over the needle plate (2) before starting of new stitching. The chain (16) is formed on a primary tab (12) provided on a side edge (11) of the needle plate (2) and an auxiliary tab (13) disposed parallel to and in side by side relation with the primary tab (12).
