Patent GB-2112357-A (GB)
Title: Improvements in or relating to load-carrying vehicles
Inventor: BOUGHTON THOMAS TRAFFORD
IPC: B60P1/64
Filed: 1981-12-23
Abstract: This invention relates to load- carrying road vehicles provided with means for hoisting a transport frame (2) on to the vehicle and offloading it from the vehicle and also for tipping the frame with respect to the vehicle. In accordance with the invention, the transport frame 2 is locked to the chassis when it is in the transport position but can nevertheless be tipped relative to the vehicle when required. In the final phase of loading the transport frame on to the vehicle, anchor members (19) on the frame slide under hooks (20) on the chassis of the vehicle, thus locking the frame to the vehicle chassis. In addition during this movement an engagement plate (18) on the frame slides under a hook on the front beam (5) of the lifting apparatus. The front beam is pivotally connected at 16 to a rear beam (3) which is itself pivotally mounted on the chassis. When the frame is to be tipped, it is moved back sufficiently to disengage the anchor members (19) from the hooks (20). This movement also causes actuation of a locking device (21) to lock the front beam (5) to the rear beam (3). At this stage the plate (18) is still engaged below the hook on the front beam (5). <IMAGE>

Title: Tape drive methods and apparatus with tape slackening feature
Inventor: SERAFINI JOSEPH JAMES
IPC: G11B15/18
Filed: 1982-12-15
Abstract: Methods and apparatus for driving a tape (15) relative to a slant track recording scanner (12) or other surface employ an electric motor (23) rotating in a first sense of rotation for an advancement of the tape (15). The advancing tape is tensioned into engagement with the surface. The motor is selectively decelerated to stop the tensioned tape. In practice, this could bind the tape to the particular surface, rendering subsequent tape advancement difficult. The disclosed invention slackens the tensioned tape (15) from the surface (12) by rotating the motor (23) in a second sense of rotation opposite to the mentioned first sense of rotation upon deceleration of the motor. The back EMF of the decelerating motor may be utilized for this purpose. The electric motor is stopped after a predetermined number of revolutions in the second sense of rotation. <IMAGE>

Patent GB-2143752-A (GB)
Title: Centrifugal separation
Inventor: ANDRES URI
IPC: B04B1/04
Filed: 1983-07-08
Abstract: A continuous-flow mechanical centrifuge 10 has a separation chamber (defined by inner and outer walls 11,12) divided into a number of compartments by dividing walls 17. Flow of material to be separated is directed in an axial direction and is divided between compartments, the flow in a particular compartment then being generally contained therein until exit from the other end of the centrifuge. Upon rotating the centrifuge, pressure is exerted by the liquid on the dividing walls, instead of causing viscous friction between the liquid and the outer wall of the chamber as would be the case in a non-compartmentalised centrifuge. Thus there is no tendency for layers of liquid to be formed having non-equal rotational speeds and form complex mixing patterns. In the preferred arrangement, adjustable inlet and outlet means are provided so that the introducing radius of the material inflow can be varied, as can the separating radius of the two outflow paths of the two separating fractions, thus providing considerable flexibility of operation. <IMAGE>
