Title: Means for attachment to an elongated member
IPC: F16G11/00
Filed: 1981-05-07
Abstract: Attachment means for attaching a device to an elongated member, such as a sweep wire for mine sweeping operations comprise an outer elongated component (1) and an inner elongated component (2), each having a longitudinally extending slot therein. The component (2) can be pushed within the component (1) with a sliding motion until resilient tongues (19) on the component (2) engage within notches (20) in the component (1) to define a locked position. The two slots are then closed along their lengths but cooperate to define a central passageway by which the means may slide along the elongated member, from which the attachment means is unlikely to become separated, thereby overcoming a problem with prior designs. Alternatively, the slots may be of such size that the means grips the member. <IMAGE>

Title: Winding web at constant winding density
IPC: B65H18/20
Filed: 1981-11-11
Abstract: Rider-roll pressure is controlled using a microprocessor so that the total weight of the rider-roll and the reel wound web, and hence the winding density, remains constant throughout a winding operation. The reel bears against a carrier drum during winding. The rate at which web is unwound from an unwind reel is monitored either by length using an optical encoder or by weight using load cells in the web unwinding stand. The microprocessor continually calculates the required rider-roll pressure from the monitored rate and from operator input parameters relating to the width desired total length and the density of the wound reel web, and increments the rider roll pressure accordingly. The rider roll can be driven. A VDU can be used to continually display the final weight of the reel being wound, the instantaneous weight of the reel and the instantaneous weight of the rider roll.

Title: Droplet ejector with control of fluid inlet to a reservoir
Inventor: HOWARD ROBERT
IPC: B41J2/045
Filed: 1985-01-11
Abstract: A droplet ejector which is particularly useful as the driving head in a "dot-on-demand" ink jet printer selectively connects an ink supply (30) to an auxiliary reservoir (26) from which ink is expelled a droplet at a time in response to driving pulses. The connection is regulated to isolate the auxiliary reservoir from the main supply during drop ejection, and to thereafter open the auxiliary reservoir to the main supply following droplet ejection in order to replenish the contents of the reservoir. The control is achieved by the use of two synchronised transducers (20,22), the first transducer (20) operating to eject a droplet and the second transducer (22) operating to connect and disconnect the reservoir (26) from the supply (30) (Figs. 2-4 show stages of operation). The ejector provides close velocity control and is readily accommodated to variable-density printing. <IMAGE>
