Title: Compacting and weighing material in containers
IPC: G01G21/00
Filed: 1978-12-07
Abstract: A machine for compacting material in an open-topped container includes a pressure platen 26 having a pressing surface 28 and a fluid- operable ram disposed to drive the platen to exert the compacting pressure on the material. Two levers 52, 56 are mounted adjacent to the platen swingable between a first, weight-measuring position 52A, 56 wherein their ends respectively project beyond opposed sides of the platen and a second, material-compacting position 52, 56A wherein the levers are disposed wholly inboard of the platen. The machine includes chains 60 for connecting the lever ends to a container to be weighed and an indicator responsive to the pressure of the fluid within the ram when the action of the ram is reversed to lift the platen, thus giving an indication of the weight of the container and its contents. <IMAGE>

Title: Tape transport apparatus and method
IPC: G11B27/10
Filed: 1979-10-19
Abstract: In the transfer of a web from reel to reel in a web/reel assembly respective speed detectors 56, 58 generate electrical pulses at rates proportional to their reel speeds for monitoring the web movement. The time to produce a given number of pulses from each reel is determined and the ratio between the measured results is utilised to provide the ratio of the speeds of the reels. Knowing other parameters characterising the type of web/reel assembly the web position can be determined from this ratio. By the use of further means, 66, 68, 80, the information can be employed to control web movement to bring the web to a required position and/or to indicate its instantaneous position. The invention has particular application to controlling and operating magnetic tapes, especially cassette tapes, e.g. to effect a high speed search for a target playback and/or recording position. <IMAGE>

Title: Control valve assemblies for dual hydraulic braking systems
IPC: B62D11/08
Filed: 1981-06-09
Abstract: In a dual hydraulic braking system in which brakes (6a) on opposite sides of a vehicle can be applied simultaneously for retarding or independently for steering the vehicle, a dual control valve assembly (6) ensures that the brakes on one side cannot be applied before the brakes on the opposite side. When the brakes on one side are to be applied independently, a stem (20) carrying inlet and exhaust valve heads (19 and 21) moves with a pedal-operated piston (12) so that the exhaust valve head (21) engages with a valve spool (25) to close an exhaust passage (28). The spool (25) moves with the piston (12) and head (21) until it is arrested by a stop face (32), whereafter a seating (18) on the piston (12) moves away from the inlet valve head (19) to allow pressurised fluid to be supplied to the outlet (24) for the brakes. When the brakes are to be applied simultaneously, a volume of fluid trapped in a transfer connection (31) between the exhaust valve heads (21) arrests movement of the spools (25) to ensure that the inlet valves open simultaneously. <IMAGE>
