Title: Method of and apparatus for removing and collecting fibre waste from spinning machines
IPC: D01H11/00
Filed: 1970-06-05
Abstract: 1307762 Air filter PARKS - CRAMER (GREAT BRITAIN) Ltd 5 June 1970 [10 June 1969] 27411/70 Heading BIT [Also in Division D1] In a method of removing and collecting fibre waste from spinning units of a spinning machine a stream of air carrying fibre waste from the units via a duct is alternately directed to one of two channels in a housing, each channel containing a filter from which the waste is removed when the associated channel is being by-passed by the air stream, access to the channels being by way of normally closed openings, and the flow of air through the one channel being unaffected by the isolation of the other channel. Air carrying the fibre waste from the units is sucked into housing 10 from duct 20 by a fan 26 driven by motor 26c. The interior of the housing is partitioned into a rear chamber 23 communicating with the duct 20 and two channels 30, 30a, each of which communicates with the chamber 23 via ingress openings 36, 36a respectively. A filter 34, 34a is positioned in each channel 30, 30a adjacent a respective egress opening 37, 37a. Each ingress opening 36, 36a is closed by a freely pivoted flap 40, 40a, and the egress openings 37, 37a are closable by a pivoted member 41 such that one opening 37, 37a is open while the other opening 37a, 37 is closed. In operation, the opening 37 is closed by the member 41 and the fan 26 sucks the fibre waste conveying air stream through the channel 30a, the force of the stream keeping the flap 40a open, and at the same time creating a suction at the rearward side of the flap 40 to maintain the flap 40 closed. The fibre waste is collected on the filter 34a until the build-up is such as to reduce the air flow in the channel. The member 41 is then moved to close the egress opening 37a and open the egress opening 37. This movement of the member 41 may be automatic in response to change in air pressure detected in the channel or after a predetermined time interval or may be manual. The force of the suction keeps the flap 40 open and the flap 40a closed. The housing 10 is provided in its side walls with openings 47, 48 and 47a, 48a providing access to the channels 30, 30a for the removal of accumulated fibre waste in the channel and on the respective filter. The filter may be mounted on rails to be removed for easier cleaning. An audible or visual signal may be mounted on the machine to indicate when the air stream should be diverted from one channel to the other.

Title: Modulated sonic signal generator.
Inventor: KING JOSEPH WARD
IPC: G10K9/02
Filed: 1968-06-11
Abstract: 1,171,728. Whistles. CLEVELAND TECHNICAL CENTER Inc. 11 June, 1968 [7 July, 1967], No. 27648/68. Heading G5J. The amplitude of the signal produced by an ultrasonic wave generator of the kind in which a jet of gas 7 impinges on a cavity 11 is controlled by a transverse jet of gas 17 which intersects the first jet before it impinges on the cavity and thereby deflects it to control the amount of gas reaching the cavity. Preferably jet 7 intersects jet 17 at a point as near as possible to the orifice from which jet 17 issues. The arrangement illustrated is a Hartmanntype whistle, but reference is also made to the control of a Galton whistle. Jet 17 may be controlled by a motor-driven, cam-actuated valve mechanism 19a-19f which functions to produce on/off modulation of the ultrasonic signal. Alternatively jet 17 may be a continuous flow which is varied in pressure so as to bring about a corresponding variation in the amplitude of the generated signal. Reference is also made to the manual control of jet 17. Jets 7 and 17 may be of the same or different gases, reference being made to air and hydrogen. The surfaces from which jet 7 issues and in which cavity 11 is formed may extend transversely of the jet in the form of portions of spheres, Fig. 2 (not shown). A cylindrical member may surround jet 7 at a position between cavity 11 and the point of intersection by jet 17, Fig. 3 (not shown). An arrangement is also described, Fig. 4 (not shown), in which a jet of gas is drawn towards the cavity, so as to impinge thereon, by sub-atmospheric pressure maintained in a chamber surrounding the member in which the cavity is formed.
