Title: Protection valves for road vehicle braking systems
IPC: B60T17/18
Filed: 1974-04-17
Abstract: 1471593 Pneumatic brake valves FABRYKA OSPRZETU SAMOCHODOWEGO POLMO 17 April 1974 [20 April 1973] 16849/74 Heading F2F A protection valve assembly comprises a housing 1 with a seat 4 co-operating with a spring biased valve member 5 which is actuatable by first and second pistons or membranes 10, 19 which can interact by relative mutual convergent movement by means of a thrust rod but are separated by a partition 2 one piston or membrane 10 having opposed chambers 23, 24 connected respectively to a main rear braking circuit and to an auxiliary rear braking circuit, a movable valve member being mounted in a wall of the chamber 24 and actuable by movement of the piston or membrane 10 by pressure in the chamber 23 against pressure in the chamber 24 to open a passageway in the wall, chambers 21, 22 on opposite sides of the piston or membrane 19 being connected respectively to an auxiliary control valve 31 and to a main front braking circuit so that the piston or membrane 19 is movable to move the other piston or membrane as above by pressure in chamber 21 as opposed to pressure in chamber 22. Under normal operating conditions (controlled by a brake valve 32) the piston 10, is in a lower position causing the member 5 to communicate the chamber 24, coupled to spring actuated fluid released auxiliary rear brake cylinders, with a chamber 25 connected to an auxiliary air supply, thus retaining the auxiliary cylinders inoperative. However, if the main rear brakes loose their pressure supply, the chamber 23 is vented, thus causing the pistons or membranes 10, 19 to rise, communicating the auxiliary cylinders to atmosphere for brake actuation. With no actuation of the main brakes for front and rear, venting of the chamber 21 by the auxiliary control valve 31 produces auxiliary cylinder actuation, the pressures in chambers 22, 23 balancing (even if they are changing) so that the pressure in chamber 24 raises the piston 10 to vent the auxiliary cylinders. The rate of pressure decrease in these cylinders is proportional to the decrease rate in the chamber 21. Likewise in the main rear brake circuit failure situation, the cylinder pressure decrease rate is proportional to the main circuit brake pressure increase rate communicated to the chamber 22.

Title: Improvements in and relating to the control of model aircraft
IPC: A63H27/00
Filed: 1956-06-01
Abstract: 813,184. Model aircraft. ZAIC, F. June 1, 1956 [July 21, 1955], No. 16987/56. Class 4. A model aircraft is provided with automatic control mechanism which, during the relatively high speed of launching, moves the elevator to a no-lift position and then moves it upwardly when the aircraft speed decreases to ensure a correct landing approach. The aircraft comprises, at the tail end of the fuselage 11, a fin 12 and a tail plane 14 having an elevator 15 pivoted thereto at 16. A control vane 21 is pivoted at 22 to fin 12 and urged outwardly therefrom by an elastic element 24, the trailing edge of the vane being connected by a flexible link 28 to the trailing edge of the elevator 15. Pivotal movement of elevator 15 is limited by the lower edge of fin 12 and a notched extension 18. During the relatively high speed of launching airflow acting on vane 21 forces it against fin 12 thereby slackening link 28 and allowing the elevator to take up a no-lift position. After the launching force has been dissipated and the. speed of the aircraft reduced the tension in element 24 will pull the vane 21 outwardly from the fin and this movement will be transmitted through link 28 to elevator 15 causing it to move upwardly and trim the aircraft to a high angle of attack suitable for landing. The aircraft will be caused to circle during landing by the offset deflection of vane 21. The vane 21 may be mounted on tailplane 12 in spaced relation to fin 12 or it may be mounted on the fin so that its lower rear edge may cooperate with one or two cam surfaces secured to the elevator, the elastic element being connected between the elevator and the tail plane. In a further embodiment, the elevator or pitchcontrolling member may be mounted on the trailing edge of the wing of a tail-less all-wing aircraft.
