摘要:
In a textile machine provided with displaceable means for carrying out an operation utilizing air pressure, a main duct is disposed along the length of the machine, and the main duct is provided with a longitudinal aperture covered with a flexible covering member which permits formation of a space by deforming the skirt portion of the covering member. A connecting pipe of the displaceable means is inserted into the main duct through the space and the connecting portion is sealed by a sealing member secured to the pipe during the displacement of the displaceable means.

Apparatus for handling yarn ends during a donning operation on a textile machine wherein in each operation unit, a yarn package is formed on a bobbin rotatably held by a cradle and rotated by the friction roller of a take-up mechanism. Just before or after doffing a full yarn package from the take-up mechanism, a yarn passage is formed by a yarn which is continuously supplied from the operation unit at a position in front of a part of the peripheral surface of the friction roller which the yarn passes over during the normal take-up operation. A fresh bobbin urges the yarn of the yarn passage toward the friction roller and then the fresh bobbin held by the cradle is rested on the friction roller. The yarn connected to the full yarn package is severed during the operation.

An empty bobbin supply device for use in a doffing machine which travels in front of spinning units and is adapted for doffing a cheese and donning an empty bobbin in place thereof. This empty bobbin supply device has a reserve box, a reserve conveyor and a horizontal transfer conveyor, which are all positioned substantially in a vertical direction. An empty bobbin comes downwardly by gravity from the reserve box and is received between transfer plates of the reserve conveyor. The bobbin is then transferred downwardly by the circulating reserve conveyor, and in the absence of a bobbin on the horizontal transfer conveyor, the bobbin is delivered therefrom, while when a bobbin is present on the transfer conveyor, the bobbin remains on the reserve conveyor. The terminal of the horizontal transfer conveyor serves as a stand-by position for an empty bobbin in the doffing portion.

An improved method and apparatus for making yarn packages of cheese form by winding units of a textile machine, wherein a bobbin of a yarn package is rotatably supported by each cradle turnably supported by a pivot shaft secured to a bracket in such a condition that the contacting pressure between a yarn package and a friction roller for rotating the yarn package is gradually decreased in an exponential manner according to the increase in the size of the yarn package and the above-mentioned change of the contacting pressure is attained by utilizing means for compensating the contacting pressure which connects the cradle with the bracket.

A filter with which it is possible to control the relationship between a pass band and an attenuation band. In this filter, for example, a single-stage trap filter is electrically connected to a three-stage band pass filter via a coupling capacitor. The trap filter has a serial resonance section composed of a resonator and a resonance capacitor. The serial resonance section is connected in parallel to a capacitive reactance element (capacitor), and a serial circuit composed of an inductive reactance element (inductor) and a PIN diode as a switching element. The capacitive reactance element and the inductive reactance element both serve to make an admittance of the trap circuit substantially zero.

Grooves are formed on the connection faces of the dielectric basic plates as a dielectric resonator, and also, an internal conductor is provided on the inside face, and coupling electrodes are formed on the other dielectric basic plate. These three dielectric basic plates are connected so that the coupling electrode effects capacity connection between internal conductors and the coupling electrode effects capacity connection between the internal conductors, whereby an earth electrode (external conductor) can be formed on almost full face on the reverse face side of the dielectric basic plate and the reduction of Qo of the resonator and the electromagnetic field leakage can be prevented.
