Title: Roll nip die for extruding hot plastics sheet - to produce e.g. PVC webs at relatively low shear rates and temperatures
IPC: B29C48/08
Filed: 1977-05-16
Abstract: A die device for extrusion of hot plastic sheet comprises a cylindrical chamber incorporating a coaxial rotor for distributing through the chamber melt received at one or more inputs from an extruder or equivalent source. The melt is discharged from the chambe between two contrarotating rolls aligned parallel and tangential to the chamber. Used esp. for generating sheet stock for feeding a calendar roll nipt with e.g. PVC based compositions. The material can be moved and discharged at relatively low shear rates and temps. and can be optimum coniditons for entering a calendar. Independent control of the temps. and speeds of the extruder screw, the chamber rotor and the die lip rolls allows each to be optimised for its purpose, resulting in greater throughputs, flexibility and efficiency than conventional screw extruders where the screw design is a compromise between plasticization pumping and throughput requirements.

Patent ES-469191-A1 (ES)
Title: Manual fluid pressure controller
IPC: G05D16/10
Filed: 1978-04-26
Abstract: A manual fluid pressure controller has a handle with integral cam which mates with a non-rotating cam follower. Rotation of the handle causes displacement of the cam follower which transmits a force through a metering spring to a metering piston. The metering piston actuates a combined inlet-exhaust valve to admit or exhaust fluid pressure to its one face until the spring force on its other side is balanced. The fluid pressure at the face of the metering piston is connected to the load whose pressure it is desired to control. A cam stop, integral with the cam follower cooperates with a matching stop on the handle to limit handle travel.

IPC: B60L/
Filed: 1981-01-07
Abstract: PURPOSE:To greatly increase the effective tractive force with respect to acceleration, by providing a current pattern operating circuit performing control as a speed function and a current pattern limiter generating the same current patterns as the speed function of adhesive coefficient. CONSTITUTION:A current limiting value setter PT sets the acceleration current IREF of the electric car.

The current pattern I is a pattern which decreases with the increase of the speed V in inverse proportion. Furthermore, the output signal of the constant current limiting circuit ACR is given to phase shifters PS1 and PS2 of choppers CH1 and CH2, and the current conduction rate of the choppers are controlled so that the main motor current IM becomes the pattern currnt given by the limiter CL.

Patent ES-8204681-A1 (ES)
Title: Multi-axis force stick, self- trimmed aircraft flight control system
IPC: B60N2/75
Filed: 1981-03-31
Abstract: A four axis force stick provides signals indicative of force applied to the stick in an axis corresponding to a control axis of an aircraft, including pitch, roll, yaw and lift/speed. The force-related signals are applied through proportional and integral gain signal paths to operate electrohydraulic servos that control the aerodynamic surfaces of the aircraft, such as the cyclic and collective blade pitch of the main rotor and the tail rotor blade pitch of a helicopter, or the ailerons, rudder, elevator and thrust of a fixed wing aircraft. Signal conditioning provides a dead band to avoid integrating minute, inadvertent force stick signal outputs, and vernier sensitivity at low forces with high gain at high forces. Analog and digital embodiments are discussed. The relationship between this wholly new mode of aircraft control and ancillary aircraft functions, such as ground steering, autopilot and stability functions, are also discussed. (Figure 2, not shown).
