Method for joining an upper thread with a lower thread, which includes moving at least one thread regulator from a thread receiving position to a thread delivery position, inserting the threads with the at least one thread regulator into a longitudinal groove formed in a splicing chamber, automatically admitting compressed air laterally into the splicing chamber for splicing the threads, automatic...

METHOD AND APPARATUS FOR ASSEMBLING BATTERY CELL ELEMENTS A method and apparatus for reliably assembling battery cell elements having relatively large numbers of electrode plates separated by a single interleaved spacer. The apparatus includes a rotatable element-assembly drum formed with a plurality of plate receiving slots at circumferentially spaced intervals about the periphery thereof, a firs...

A system is described for the production of rapidly solidified powder. The system contains elements for casting rapidly solidified ribbon, an in-line knife mill or a hammer mill for fracturing the rapidly solidified ribbon into shard, and either an in-line fluid energy mill, or an in-line centrifugal mill for reducing the shard to powder. The system can effectively reduce ribbon to powder in an in...

A bottle inspecting apparatus comprises means for conveying bottles while rotating the same; a first light source for exposing only the bottle finish with light; a second light source having a radiation spectrum different from that of the first light source for exposing the thread of the bottle neck; a filter for discriminating the light of the first light source scattered at the bottle finish and...

A method of testing a plant to determine the variable fluorescence of the plant, and instrumentation for carrying out the method, is described. The method has use in determining the extent to which a plant has been damaged by photoinhibitory stress, or is susceptible to damage by such stress.

A non-volatile memory storage system having non-volatile memory (10) and volatile memory. The non-volatile memory (10) will have its most significant bits memory locations (11) periodically updated in response to a growing count of data. The least significant bits information reflecting such count will be maintained in volatile memory except during power down conditions. During power down conditio...

Rotating cutting tool, in particular a drilling, milling and/or reaming tool, with a tool body having a pronounced longitudinal extension in the direction of the rotational or main axis and made of carbide or mechanically resistant material, which tool body has on its outside at least one groove running preferably at an angle to the axis differing from 0 DEG , in particular roughly helically, and ...

12 A laser surgical system for use in the operating room is suspended on the ceiling and can be moved horizontally in an X-Y direction. The system has the laser tubes, power supplies and cooling unit in the suspended assembly. A carbon dioxide laser for cutting and a neodymium YAG laser for coagulation excite a common optical channel. A third laser argon, or other wavelength, can be added to the s...

A method of fabricating a tube having enlarged ends and made of material which can be strengthened by cold working comprises fabricating a pre-form having the overall configuration of the tube but with increased outside diameters and a decreased length. The pre-formed tube is cold forged or cold rolled over its entire length to reduce its outside diameter while maintaining its inside diameter subs...

Device for converting the rotary motion of an eccentric driven by a motor shaft into an oscillating motion of a working tool in electrically powered appliances, consisting of a double-armed rocker arm and an oscillating body, connecting the rocker arm with the eccentric, composed of three connecting arms, two of which are assembled into a frame-like structure by appropriate design, whereby the ecc...

A drum brake assembly is described to comprise a dual drum brake housing mounted to a vehicle wheel or shaft to be rotated therewith. The dual drum brake housing has two axially extending, concentric, radially spaced drum surfaces defining an annular channel between them. A torque member is fixed against rotation with the vehicle wheel and an expandable friction lining assembly is mounted to the t...

The transmission includes a rotary shaft for transmitting drive to driving wheels of the vehicle, a fixed gearbox casing and a hill holder between the shaft and the gearbox casing. The hill holder, when operative, inhibits reverse movement of the vehicle and includes in series a sprag clutch and a multiplate brake. Fluid is supplied from a fluid operable control system for operating the brake and ...

The power actuator comprises a housing in which are mounted a motor-driven worm gear and an actuating shaft for controlling the operative condition of a machine element. Rotary motion of the worm gear is transmitted to the actuating shaft by one or more gear wheels and a sector gear which is fixed for angular movement with the actuating shaft. The gear wheel meshes with the sector gear. A force mo...

A thermal printer (10) has a thermal transfer medium (28) fed past a thermal printhead (21) at a substantially constant velocity by a feed roll (82) engaging the thermal transfer medium just prior to the printhead to maintain a portion of the thermal transfer medium between the printhead and the feed roll relatively stiff. The feed roll is mounted on a cartridge (30) having the thermal transfer me...

In modern ozone generators high power densities can be achieved using ceramic-based dielectrics and suitable gap widths and double cooling. By constructing the dielectric layer from dielectric powders of different grain size and binding with artificial resin, the long-term breakdown voltage of the dielectric layer can be increased to such an extent that they fulfil the operating requirements.

A process for producing an expanded or foamed body of a fluorocarbon resin comprising molding the resin in a molten state in the presence of a depolymerizable polyether compound.

Disclosed are rigid materials such as sheets, boards or tubes made of expanded polypropylene, which have a uniform specific gravity d of from about 4.1x10-6 to about 8.1x10-6 Newton/mm3, a crystallization temperature of from about 115 DEG C. to about 135 DEG C. and a flexural modulus Mf expressed in Newton/mm3 such that the ratio Mf:d is from about 1.5x108 to about 1.7x108 mm.
