Title: Improvements in devices for stabilising and controlling aircraft provided with rotatable wings, of the helicopter type
IPC: B64C1/00
Filed: 1930-03-11
Abstract: 352,521. Aircraft with adjustable rotary wing system. BREGUET, L., 115, Rue de la Pompe, Paris. March 11, 1930, No. 7952. Convention date, March 15, 1929. [Class 4.] In arrangements for stabilizing and controlling aircraft with rotating wings there is produced by means of a cam roller race, a ring provided with ball bearings or analogous means connected with the main frame of the apparatus and under the pilot's control, an angular displacement of the wing blade about an axis perpendicular to the axis of rotation of the wing device, or a rectilinear motion in a plane containing the said axis which displacements subject the apparatus to a couple tending to incline it in the contrary direction to the inclination of the rolling ring or cam. In a simple form a cam ring is mounted on a spherical bearing surrounding the wing-carrying shaft and may be tilted so as to engage rollers carried by the wing roots and thus displace the wings during a part of their rotation. Fig. 2 shows a form in which the movements of the wing pivots are controlled throughout their cycles. Wings P. P<1> are hinged to sliders h working in radial slots formed in a driving bell-shaped member J<1>. Movement of the sliders in the vertical plane is controlled by a ring l forming part of a universally mounted ball bearing which can be tilted in any direction by links connected to a similarly mounted disc c<1> which is always maintained parallel to it and is controlled by the pilot through a shaft p having a hand-wheel o. A servomotor may be employed. The wing system may be engine driven through a clutch. In a modification, Fig. 3, wings P, P<1> are hinged to axles d<1> and their movements are controlled by short pivoted connecting-rods v, v<1> socketed in the outer ring of a bearing similarly mounted to that of Fig. 2. Two sets of oppositely rotating coaxial wing systems may be employed. In one form, Fig. 4, wing blades P<2>, P<3> are universally hinged to lever arms L2, L3 pivotally mounted on concentric driving shafts. The inclination, in the vertical plane, of the levers associated with the lower wings is controlled by means similar to those shown in Fig. 3. A similarly mounted ball race for the upper wing levers is tilted in unison with the lower one by means of a cam d<3> secured to its underside and co-operating with bearing surfaces or rollers f<2> formed on the lower wing levers L<2> concentrically with the balls by which the connecting-rods are socketed in the outer ring of the lower ball race. Means for changing the angles of incidence of the wing blades may be fitted.

Filed: 1963-03-01
Abstract: 998,000. Controlling burners. MULLARD Ltd. Feb. 12, 1964 [March 1, 1963], No. 8289/63. Heading F4T. [Also in Division G1] A radiation responsive device including a threshold actuated control means consists of a capacitor 17 in series with two parallel current paths, one of which includes a rectifier 6 and has its conductivity proportional to the radiation intensity and the other including the actuating element of the control means. The device is designed to be fed from an A.C. source at terminals 18 and 19 and the control means may be a relay 16 with contacts 15. The device may be used to monitor the burner in a furnace and to prevent a false flame-present indication being given when the flame is out but the furnace walls radiate heat. A filter 4, substantially opaque to all but the near infra-red, is placed between the source 2 and the photo-resistor 5. The circuit arrangement described generates a D.C. through relay 16 only in the presence of a flame and fails safe in respect of a considerable number of circuit faults. In modifications of the arrangement of Fig. 2 a current-limiting resistor, preferably with a high positive temperature co-efficient of resistance, may be placed between terminal 19 and capacitor 17 to act as a current limiter in fault conditions. A resistor, preferably with a non-linear voltagecurrent characteristic, may also be placed in series with the relay 16 and a resistor or capacitor then included a parallel with the relay. It is also possible to insert a protective resistor in line 8 and a portion of it may be shorted out by additional contacts on the relay unless flame-out or fault conditions exist.

Title: Improvements in automatic reclosing circuit breaker systems
IPC: H02H3/06
Filed: 1941-07-09
Abstract: 546,798. Protective cut-out systems. BRITISH THOMSON-HOUSTON CO., Ltd. July 9, 1941, No. 8661. Convention date, July 11, 1940. [Class 38 (v)] In an automatic reclosing circuit-breaker system employing two timing systems, one of which recloses the breaker instantaneously once (as in the example given) or a given number of times, whereas the other performs a given number of time-delayed reclosures, the first system initiates the operation of the second system in the event of the breaker being still open when it has completed its timing operation In the Figure a time relay 13 'energized at the first tripping by overload relay 7, closes contacts 14, 15 in succession, the former contacts causing operation of the first system once, and the latter contacts controlling a timing means 23 such as described in Specification 406,961 for producing the delayed reclosures. On overload, relay 7 energizes trip coil 6 and also a relay 9 which closes hold-in contacts 10 and at contacts 11 makes the circuit of a relay 12, which makes a holding circuit at contacts 26, and of timing relay 13. Closure of contacts 14 of the latter energizes, over back contacts 27 of the breaker, a relay 16 which closes a holding circuit at contacts 29, and the relay 17 which energizes reclosing coil 4. When the breaker closes, contacts 27 open and de-energize these relays and. supposing the 'breaker stays closed, when contacts 15 of relay 13 close, a relay 31 is energized over back contacts 32, which relay holds itself in at contacts 33, and at contacts 35 de-energizes relay 12. Contacts 26 therefore open and allows relays 12, 13, 31 to return to their original positions. If, on the contrary, the breaker does not stay in, when contacts 15 are closed a circuit is made over back contacts 36 to the coil 18 of a lock-out relay 19 which picks up and is latched in at 20. In picking up, relay 19 firstly opens its own circuit and that of relays 12, 13 at contacts 25, secondly opens the circuit of relays 16, 17 at contacts 28, and, lastly, makes at contacts 37 and over back contacts' 38 the energizing circuit 39 of the timer 23. If the breaker stays in, the timer 23 at the end of its operations energizes over back contacts 40 the release coil 21 of latch 20, to render operative the instantaneous reclosing means.
