A heat transfer apparatus for a gas turbine engine includes: a component having a wall structure defining a flow bounding surface; a chamber formed in the component, the chamber including a wicking structure, a vapor channel, and a working fluid.

An internal spur gear drive has a mounting base including one or more sets of motor mounting lugs extending therefrom, for attaching a corresponding number of drive motors thereto. A drive shaft housing containing a rotary drive shaft extends from the mounting base. A drive bell is affixed to the drive shaft distal end, and rotates therewith. The opposite end of the drive bell has an internally toothed ring gear extending therefrom. Each motor drives a pinion gear which engages the internal teeth of the drive bell ring gear to rotate the drive bell and thus rotate the drive shaft as well. The motor mounting lugs are slotted, allowing the motors to be adjusted radially relative to the drive shaft and drive bell ring gear. This provides adjustment for gear lash, as well as permitting different sizes of pinion gears to be installed on the motors for different gear ratios.

Apparatus for a connecting point between high-voltage cables, each cable having a conductor, inner conductive layer, insulation, outer conductive layer, and a sheath over the outer conductive layer and in which the conductors, from which the surrounding layers have been removed, are conductively connected to one another. The arrangement has electrical screening elements and an integral elongated sleeve body, composed of elastic insulating material and a through-hole. The sleeve body has at its axial ends, which are intended for the cable to pass through, electrical control funnels which abut the outer conductive layers, from which the sheaths have been removed. The internal diameters of the through-hole in the sleeve body, at its axial ends, are for its use in a connecting point of cables, having an external diameter of their insulation which differs by at least 10 mm, different in a defined manner and adapted to the different external diameters.

The invention relates to a method for producing a fuel injection valve (10; 10a; 60; 60a), in which a valve needle (40; 40a; 62; 62a) which closes at least one fuel outlet opening (49) is inserted into an injector housing (11), wherein that end of the valve needle (40; 40a; 62; 62a) which lies opposite the at least one fuel outlet opening (49) is guided in a valve element (32) which has a pressurized control chamber (37) which is filled with fuel, wherein the control chamber (37) can be closed on the side which faces away from the valve needle (40; 40a; 62; 62a) by a closing element (23) which forms a passage during opening and is connected at least indirectly to a fuel return line (5) which is under low pressure, wherein fuel volume which is present in the control chamber (37) flows away through the passage after opening of the control chamber (37) by means of the closing element (23), wherein the valve needle (40; 40a; 62; 62a) moves in the direction of the closing element (23), wherein the at least one fuel outlet opening (49) is opened, and wherein a delay time (t) occurs between the opening of the control chamber (37) and the opening of the at least one fuel outlet opening (49) on account of the magnitude of the volume of the control chamber (37) and on account of the rigidity of the valve needle (40; 40a; 62; 62a), which rigidity is caused by the modulus of elasticity, the diameter (D) and the length (L) of the valve needle (40; 40a; 62; 62a). There is provision according to the invention for at least the volume of the control chamber (37) to be adapted in order to achieve identical delay times (t) in fuel injection valves (10; 10a; 60; 60a) having injector housings (11) of different length and valve needles (40; 40a; 62; 62a) of different length, in such a way that the volume of the control chamber (37) is reduced in order to shorten the delay time (t) and the volume of the control chamber (37) is increased in order to lengthen the delay time (t).

A coin hopper includes a rotating disk provided obliquely upward at a predetermined angle; an outer covering unit covering at least a lower outer circumference of the rotating disk; a holding bowl continuing from the outer covering unit and holding coins; a circular supporting rack provided in a central region of an upper surface of the rotating disk; and coin stoppers being provided on the upper surface of the rotating disk and extending radially from the supporting rack in a circumferential direction to a periphery of the rotating disk at an equal interval. Coins are accepted one by one while a surface thereof is contacted with a holding surface of the upper surface of the rotating disk between the coin stoppers, are moved in one direction while a periphery thereof is held by the supporting rack, and are received from the coin stoppers during transportation by a coin receiver.

A method and system are provided for constructing large, continuous, concrete slabs without using conventional shrinkage joints. The system comprises a grid of closely-spaced crack inducers (2) arranged relative to a concrete-pouring surface and adapted to be covered by concrete. The crack inducers (2) may be connected to one another with connectors (10). The crack inducers (2) are of a size, shape and spacing to promote formation of fine cracks in the vicinity of the inducers (2) throughout the slab when the concrete sets.

A device as well as a method for forming a sausage tail on a casing material, that receives a filling product, in particular sausage meat, wherein the sausage tail at least approximately does not contain filling product at least while it is being formed. The device contains a feeding path for the casing material, which extends in an at least approximately linear direction and along which the sausage tail is formed, a supply unit for receiving a supply of empty casing material and a first unit for forming sausage tails that is capable of acting on the casing material in direction of the feeding path for forming a first sausage tail length by pulling casing material from the supply. Furthermore, a second unit for forming sausage tails is provided that is capable of forming a second sausage tail length by pulling further casing material from the supply.

A device to adjust the focus position of the therapy head of a lithotripsy system having an x-ray system, has a cross-hair disc that can be attached to an image intensifier of the x-ray system, such that extending away from the edge of the cross-hair disc are variable-length connection elements whose outer end facing away from the cross-hair disc can be indirectly or directly affixed to the image intensifier.

In a valve apparatus, an annular contact portion made of elastic material is provided on a valve portion of a valve plug. A plurality of annular grooves are formed on a proximal end surface of a valve seat member which abuts against the contact portion. The annular grooves are formed around a communication hole through which fluid flows. The annular grooves have different diameters, and are concentric with one another.

A liquid crystal display includes a cover bottom and a cover shield. The liquid crystal display includes a nut coupled to a bracket through a fastening bolt. An upper portion and a lower portion of the nut have different diameters.

The present invention provides a sharpening completion detection mechanism that does not apply a heavy load to a core tip, and especially proposes a mechanism that moves a pencil in an ejection direction immediately when the sharpening completion detection mechanism detects completion of sharpening to mitigate damage to the core. Specifically, a pencil sharpener according to the present invention includes: a slide unit that translates in pencil insertion and pencil ejection directions; a pencil biasing means supported by the slide unit; a slide locking means that locks a translation position of the slide unit upon the slide unit translating in the insertion direction; and a slide unit unlocking means that releases the lock for the translation position of the slide unit upon the sharpening completion detection means detecting a fully sharpened state of the pencil, and includes slide unit ejecting means that biases the slide unit in the ejection direction with energy stored by movement of the slide unit to a lock position.
