A cleaning system for use with a fibre opening device used in connection with the spinning of fibres into yarns wherein an opening roller is mounted for rotation in a housing incorporating a trash separation zone and a fibre stripping zone and the roller has a cylindrical working surface with combing elements projecting thereform, wherein the roller is substantially hollow and has holes in the cylindrical wall defining its working surface to permit flow of air through the wall and the interior of the roller is divided into two or more compartments, and means are provided to remove air and entrained dust and trash from a compartment adjacent to the trash separation zone, and further means are provided to insert air or other gas into a compartment adjacent the fibre stripping zone.
摘要:
An opening roller for an open end spinning machine which may be formed in one or two parts, the opening roller having a central body or hub (1) preferably provided with a central cylindrical aperture (10) therein for mounting on a drive shaft of an open end spinning machine, there being an outer ring (2) having a cylindrical external surface (7), the ring (2) supporting suitable combing elements in the form of spaced pins (14) or card wire and wherein the ring (2) is spaced from and connected to the central body (1) by means of septal walls (3) which may either extend radially or be inclined to respective radial planes passing through them, and wherein the spaces between the septal walls may be filled with a suitable plastics medium (11) which may surround the pin tails (18) if these project from the rear face (19) of the ring (2). The roller may be machined from a one-piece extrusion (FIG. 2) or after suitable machining may be assembled from two parts which may themselves be extruded.
摘要:
A lag or stave assembly for a Kirschner beater which replaces the traditional one-piece wooden lags and is preferably formed from extruded aluminium. The lag assembly is formed in two parts with a first support part which is preferably channel-shaped and can be secured to the free end of an arm or spider of the beater, and a second pinned working part removably secured along its leading and trailing edges to the upper ends of the arms of the support part, one edge, preferably the leading edge, of the working part being secured to the support part removably and hingedly, e.g. by a hook-shaped tongue engaging in a mating groove, and the other edge being fixedly secured to the other arm of the support part, e.g. by means of screws and/or any type of snap-fit or interlock. The arrangement preferably ensures that one of the parts is loaded in tension or compression when the two parts are secured together to prevent rattling.

A wave energy converter (WEC) buoy includes at least one pitch-driven WEC (“PDWEC”) device. Each PDWEC device includes two reaction masses which are placed at diametrically opposite ends of a container designed to float along the surface of a body of water and to move in response to the pitching motion of the waves. The reaction masses are interconnected so that when one reaction mass moves up, the diametrically opposed reaction mass moves down, and vice-versa. The movement of the reaction masses drives power take off (PTO) devices to produce useful energy. The reaction masses may be interconnected by any suitable linking system. One or more PDWEC device may be combined with a heave responsive device to produce a WEC buoy which can produce a power output in response to pitch or heave motion.

A defibrillator is provided with two processors for enhancing the defibrillation process. A first processor is dedicated to controlling when an electrical charge is applied to a patient. A second processor is dedicated to data operations for enhancing the coaching of the defibrillation process. The second data processor is in communication with one or more external devices for transmission and receipt of network data for further enhancing the coaching process. The second data processor allows both the defibrillator to be maintained with updated network data and software and the one or more external devices to be maintained with updated defibrillator data. Independent controllers provide multiple processing paths on critical charge and coaching functions; with the second data processor further providing redundancy control in the event of any malfunction of the first charge processor.

Apparatus for connecting a power cable to a marine vessel which is subject to pitch, heave, roll and yaw motion includes a ball and socket device for decreasing the twisting and bending of the power cable. The socket is attached to the vessel and the ball can rotate freely Within the socket but its up down motion is restricted. The power cable's outer protective sheath is attached to the ball while its conductors pass through the ball and are connected to an internal connector. A flexible cable (wire) is connected between the internal connector and electrical equipment internal to the marine vessel.

摘要:
A reaction mass and a spring are configured to form an “oscillator”. The reaction mass is coupled to, and can wrap around, a first pulley via a first belt/cable. The spring is coupled to, and can wrap around, a second pulley via a second belt/cable. The first and second pulleys are mechanically linked together and are mounted so they rotate in tandem. The diameter of the second pulley is different than the diameter of the first pulley to cause the reaction mass to travel a different distance than the spring in response to the up down motion of the reaction mass. The first and second pulleys may be circular with the second pulley being made smaller than first. Alternatively, the first pulley may be circular and the second pulley a cam of varying radius.
摘要:
Filler material, particularly for cigarette filters, is produced by feeding a first stream of substantially continuous filaments of filler material onto a pin roller which is driven at a speed such that the filaments are broken by the pins into irregular lengths and are projected from the roller in random orientations. The broken filaments are collected on a carrier stream, also comprising filamentary material, for delivery to a rod-making unit. More than one stream could be supplied to the pin roller so that the broken filaments can comprise a mixture of filaments of different filler materials. The carrier stream may comprise filler material which is different from that in the first stream and may comprise a fibrillated web.
