PURPOSE:To end yarns effectively, by specifying the yarn holding method in tying the two yarns with the entanglement using an air jet at the central part of the piled ends of the yarns. CONSTITUTION:The upper yarn YU and the lower yarn YL are inserted into the hole 27 of the nozzle 1 and the knotting bills 2 and 3 along the guide plates 4-7. The yarn YU is bent by the yarn holder 9a and held by th...

PURPOSE:To form a strong ended part by applying a turning air flow to two yarn ends which are introduced into a pneumatic nozzle and clamped at postitions before and after the nozzle to end the yarns efficiently without causing loss of twists. CONSTITUTION:The ends of the upper and the lower yarns are cut and held by the yarn end cutter and holders, and clamped by the units before and after the no...

Halides of Si and Ti, B, P, or Ge and oxygen or steam are introduced into a reaction vessel and heated in a vapor phase to form fine glass particles by oxidation or hydrolysis. The fine glass particles are deposited on a substrate. The deposited fine glass particles are heated and vitrified into a transparent glass layer, which is etched to form a core having a desired pattern by a reactive sputte...

Disclosed is a multiple target scanning electron beam X-ray source for use in high speed multiple section computed-tomographic (CT) X-ray transmission scanners. The scanner uses a single electron beam tube. The electron beam is rotated by a magnetic deflection system. The electronic scanning system is much faster than mechanical scanners and requires no moving parts that require high precision and...

A holder for a textile-bobbin tube open on both sides has the form of a crossmember, on the top side of which the bobbin tube rests. The crossmember has, at the front end, a nose which is loaded against the front end face of the bobbin tube at one point by an additional force by means of a pressing device loaded by a tension spring. The functions of carrying and holding the bobbin tube are in this...

The bladder has at least a portion of its outer surface comprising a fabric layer of cords partially embedded therein so that such cords project slightly above the rubber surface. The article is manufactured by calendering a fabric layer of cords on one side only with a coating of uncured and unvulcanized rubber, applying the layer to the bladder material with the rubber coated surface in contact ...

The present invention is directed to a combustion modified flexible polyurethane foam produced by reacting: (A) an organic polyisocyanate, (B) a polyether polyol selected from the group consisting of (i) a dispersion of a polyurea and/or polyhydrazodicarbonamide in a relatively high molecular weight organic compound containing at least two hydroxyl groups, wherein the concentration of the polyurea...

A reinforced reaction injection molding of polyurethanes is prepared by reacting an organic polyisocyanate, a polyoxyalkylene polyether polyol, a chain extending agent, a catalyst, optionally a blowing agent and glass fibers. The glass fibers form a stabilized dispersion in the polyol by employing as a suspending agent the reaction product of a polyamine and a polyester.

Signals at selected points on a test device place indicia on a record indicating, for each selected point, a selected logical active level and an initial polarity level. At preselected time intervals, levels, level changes and the number of transitions per change appear on the record as human-readable symbols. Each selected points signals are translated into digital representations which are store...

A pigment for colouring linear polyester in the melt was prepd. by mixing with pigment, NaCl and diaceton alcohol. Thus, 5 kg CI red pigment 166 was mixed with 30 fine powder NaCl and 4.5 kg diaceton alcohol, wet-milled by hammer mill, and died in the vacuum oven at 75≰C for 48hr. 5 kg Pigment was mixed with 5 kg polyester powder in the roller gear bed for 3 hr, died at 60-70≰C for 72 hr under vac...

Flexible polyurethane foam having reduced tendency to form burning embers and which produces a char when it is ignited and burned is provided by incorporating into the reaction mixture before foaming an aldehyde or an aldehyde generator. In a preferred embodiment, flexible polyurethane foam of increased flame retardance is provided by also incorporating a flame retardant into the reaction mixture ...

PURPOSE:To normally execute control when turning on a power source, to entirely stop runaway of a program, and exactly discriminate whether a position of each ROM is correcte or not, by a reset vector entered into each ROM, even in case of an erroneous insertion of plural ROMs. CONSTITUTION:When a power source is turned on, an instruction part 18 outputs the uppermost order address of each ROM. By...

PURPOSE:To elevate reliability of a data, by logically detaching a fault storage device from a processor in a system, in case when a multiplexed storage device become faulty. CONSTITUTION:Access from processors 10, 20 is executed simultaneously to 2 storage devices 30, 40 through interface signal lines 10b, 10c, 20b and 20c. When an error signal is sent from a discriminating information sending-ou...

PURPOSE:To check an existing ROM, by providing an ROM having the same contents as the existing ROM, comparing the information of both ROMs corresponding to a read-out address of a processor, and generating an alarm in case of dissidence. CONSTITUTION:When a read-out address is outputted, an ROM3 and an ROM3' are accessed respectively, and is outputted to a data bus 4 and a comparing circuit 5, res...

A powder metallurgy product comprising iron and chromium, and/or aluminum and characterized by elongated grains that are stable at elevated temperatures.

The essence of the method of extracting or recovering meat of small crustaceans, e.g. antarctic krill, resides in that crustaceans are introduced into an air flow relative to the surface of the crustaceans at a given velocity required for creating a pressure drop across the internal space or cavity of the crustaceans and the air flow. Consequently, the inter-cavity pressure breaks up the shell and...
