Title: Hydraulic adjustment for aircraft control surfaces - has two hydraulic pressure sources and sets of three pilot valves for six control signals
IPC: B64C13/36
Filed: 1974-12-13
Abstract: The control arrangement has an electric control circuit which responds to a first position-selection input signal to give six nominally identical electric control signals. The system further incorporates six pilot valves which respond to the electrical control signals to generate servo pressure signals. Six intermediate adjustment drives respond to the servo pressure signals. Elastic mechanical couplings connect the adjustment drives and the control valves to one another. A first set of three pilot valves and one of the main control valves is connected to one of the hydraulic supplies while a second set of three pilot valves and the other main control valve are connected to the other hydraulic supply. An output adjustment drive responds to the main control valve.

Title: Automatic titration eliminating inaccuracies - using signals, representing titrant vol. increments and potential difference between electrodes immersed in soln.
IPC: G01N31/16
Filed: 1974-12-06
Abstract: An electronic method for carrying out a titration on a solution automatically uses the first and second differentials dE/dV and D2E/dV2 to obtain a point where d2E/dV2 becomes zero when the equivalent point is reached in the titration. Here E = potential differences between the electrodes immersed in the soln. V = quantity of titrating soln. added. The zero point is detected by an electronic circuit operating automatically. The addn. of the titrating soln. is slowed down on either side of the equivalent point so that the ratio of background noise to signal strength tends towards zero. The detection of the zero point can be used to stop the addition and to send a signal to any suitable receiving appts.

Title: Press tool for progressive laminate consolidation in evacuated mould - to avoid surface air entrapment or compression of laminate cores
IPC: B30B15/06
Filed: 1977-03-31
Abstract: A press tool for consolidating laminates covered on the upper face with a wet coating is provided with a flexible cover which can be progressively deployed laterally from initial contact along the centre of the cavity, while a suction manifold simultaneously evacuates the mould from the borders of the cavity. Opt. a rubber sheet or inflatable sleeve is interposed between the overhead panel and the laminate. Coating is of thermoplastic or thermosetting material. The flexible cover is suspended from arrays of pistons which are progressively actuated in pairs ranked symmetrically with respect to the mould centre-line. The combination of progressive cover contact and evacuation results in even cover contact without air entrapment and consequent surface blemishes. Progressive parting of the cover from the laminate face from the borders inwards avoids overstressing of the laminate, requires less force than parting a rigid plane platen from all parts of the laminate surface simultaneously.
