A device for inserting a weft yarn in a shed of the jet operated weaving machine provided with a control means for controlling the carrying action of the weft yarn, which is carried by a plurality of pressure fluid flows through a guiding channel formed in a comb arranged in parallel condition to a reed. The comb comprises a plurality of guiding plates and an air escaping passage formed between every two adjacent guide plates in such a condition that the quantity of the escaping air which flows through each escaping passage is maximum at a predetermined portion of each escaping passage. The above-mentioned control means comprises the above-mentioned escaping passages.

A constant combustion engine wherein the air and the fuel are mixed at a predetermined air-fuel ratio, ignited and burned; the water is injected into the combustion products to generate the mixture of the combustion products and water vapor; and said mixture is charged as the working gases into a fluid motor. With a low grade fuel, a higher thermal efficiency may be obtained, and the emission of pollutants may be minimized.

Constant combustion engine

An open end spinning machine includes a row of spinning rotors each connected to spindles rotatably supported in their predetermined axial position by associated twin-disk mechanisms and driven by a belt moving across the spindles. When the spindle is subjected to an external axial force in either of opposite axial directions due to disturbance of a right-angled relationship between the belt and the spindle, an arrangement according to the invention causes the spindle to be subjected to a force, the direction of which is directly opposite to and the strength of which is in proportion to that external axial force due to the disturbance of the right-angled relationship, whereby the spindle is maintained in the predetermined axial position.

Arrangement for preventing axial displacement of spinning rotor spindle

Disclosed is an open-end spinning apparatus provided with a fiber-bundle supply mechanism disposed to a casing and a combing roller disposed in the casing, so as to separate the supplied bundle of fibers into individual fibers, and a spinning rotor for forming a yarn from said individual fibers; a fiber carrying passage is formed in the casing at a position between the fiber-bundle supply mechanism and the spinning rotor, the fiber carrying passage being provided with a combing section where an action of the combing roller is imparted to the bundle of fibers delivered from the fiber-bundle supply mechanism so that the fibers of the fiber-bundle are separated from each other from; a pneumatic or mechanical means is provided for positively introducing the above-mentioned individual fibers to a part of the cylindrical surface of the combing roller; so that, consequently, all fibers contained in the bundle of fibers fed from the fiber-bundle supply mechanism receive effective combing action of the combing roller in the combing section of the fiber carrying passage.

Fiber separating device of an open-end spinning apparatus

In an open-end spinning apparatus provided with a fiber feed mechanism, a combing roller for separating a bundle of fibers supplied from the feed mechanism into individual fibers, a spinning rotor for receiving individual fibers delivered from the combing roller and for forming a ring shaped bundle of fibers on a fiber collecting zone formed at an inside wall position having a maximum lateral diameter with respect to a rotational axis thereof, and a yarn guide means for introducing a yarn formed in the spinning rotor toward a takeup mechanism disposed at a position outside the spinning rotor, a plurality of air streams are directly blown toward the fiber collecting zone by means of air stream creating means so that the ring shaped bundle of fibers deposited on the fiber collecting surface is urged toward the inside wall of the rotor at this collecting zone by the action of the air stream together with the centrifugal force of the fibers which is created by the rotation of the spinning rotor.

Spinning rotor utilized for an open-end spinning apparatus

In a spinning device of an open end spinning machine, a silver is fed to and passes through a feeding and opening device which opens the silver into individual fibers and feeds them into a rotary spinning chamber where they are collected and discharged as a finished yarn therefrom. In order to clean the fibers, when they pass through the feeding and opening device, dirt of the fibers is adapted to be thrown out by centrifugal force and leaves the fibers through a dirt discharge opening and enters through an intermediate duct into a dirt collecting chamber. The chamber is provided with an air inlet opening into the atmosphere and an air outlet connected with a source of negative pressure to produce a current of air which flows through the air inlet and outlet and by which the dirt collected in the chamber is continuously removed out of the chamber. A part of the air current tends to be directed through the intermediate duct to the dirt discharge opening. However, the intermediate duct has a portion with a cross-sectional area sufficiently smaller than that of the dirt collecting chamber so that the speed of that part of the air current becomes smaller than a terminal speed of the dirt.

Dirt removal in spinning device

A fuel supply system for use with an internal combustion engine of the type in which the air intake quantity is substantially in proportion to the engine speed and the opening degree of a throttle valve and the fuel to be mixed with the air is injected through a fuel injection nozzle, said fuel supply system comprising pump means which discharges the fuel in proportion to the engine speed, and a fuel shunt device for supplying a part of the fuel supplied from said pump means to said fuel injection nozzle while recirculating the remaining fuel to said pump means, said fuel shunt device having first valve means for automatically controlling the area of the opening of a passage hydraulically connecting said fuel shunt device to said fuel injection nozzle in proportion of the discharge rate of said pump means, and second valve means for automatically controlling the area of the opening of a return line hydraulically connecting said fuel shunt device to said pump means in inverse proportion to the opening degree of said throttle valve, whereby the air-fuel mixture with a substantially constant air-fuel ratio independently of the speed and load of the engine may be charged into the engine.

Fuel supply system for internal combustion engine

In a spinning device of an open end spinning machine, a sliver is fed to and passes through a feeding and opening device which opens it into individual fibers and feeds them into a rotary spinning chamber where they are collected and discharged as a finished yarn therefrom. In order to clean the fibers, when they pass through the feeding and opening device, dirt of the fibers is adapted to be thrown out by centrifugal force and leaves the fibers through a dirt discharge opening into a dirt collecting chamber. At this time, loss of fibers has to be prevented and for such purpose an air supply duct is arranged adjacent to the dirt discharge opening to introduce an air current into the fibers opposite to the direction of movement of the dirt particles. The air supply duct is adapted to allow the speed, the flow rate, and/or the direction of the air current to change in accordance with the conditions mentioned in the following description.
