Abstract: A web of fibers delivered from a drawing machine is assembled into a sliver which passes into a guide duct, then passes between takeup rollers into a can coiler. Downwardly inclined air-escape holes are pierced in the wall of the guide duct in order to discharge the air entrained by the sliver. There is consequently no swelling of the sliver on the delivery side of the takeup rollers and no pressure rise towards the guide duct inlet, thereby facilitating the introduction of the web into the duct.

Abstract: A coupler for coupling together two pipes comprises a substantially cylindrical body on which a plurality of hook arms carrying latches are pivotally mounted. An actuator ring is rotatably mounted on the coupler body and has a cam surface which is arranged to cause the hook arms to pivot to move the latches into and out of a position in which they serve to lock a flange at the end of a pipe to a front flange of the cylindrical body. The pipe flange can be guided onto the coupling by guides and the guides are also effective to hold adaptor plates on the flange so that the coupler can be used to couple pipes of different diameters. No axial movement of any of the components of the coupler takes place during coupling, movement of the actuator ring being purely rotational and movement of the hook arms and latches being purely pivotal.

This transport device is capable of moving towards the film card, so that the film card passes between the disks. One of the disks is driven so that the film card is transported as soon as it passes between the disks. Due to the arrangement of a pair of disks, the transport device is extremely flat so that it can withdraw a film card from a cassette without the need for it to be slid into the induction region of the transport device by means of, for example, a ram.

Abstract: A diaphragm assembly is designed to follow a drop in the level of a working fluid filled in a reservoir used with a master cylinder for the purpose of cutting off the communication between the working fluid and the outside air. The diaphragm includes a pair of opposite lower steps in the axial direction. Each of the steps comprises an upright flat portion and an upper flat portion which form parts of the bottom wall and side wall of the diaphragm, when the level of the working fluid in the reservoir reaches a predetermined lower limit. The upper flat portions of the steps are inclined to at a given angle to the horizontal, thus forming an air passage.

Abstract: In order to homogenize and to obtain a uniform temperature distribution in a plastics substance, which is to be extruded between an inner and an outer component, in a nozzle, the substance is made to pass a bearing structure comprising a number of rolling bearings, where the balls serve as kneading bodies. The inner and the outer components of the orifice rotate in opposite directions, which will orientate the molecular chains in the surface zones of the extruded products at an angle to the direction of extrusion. In this manner the structure of the product is enhanced, while simultaneously the kneading operation reduces the risk of impurities in the plastics compound causing weak spots in the product.
