The layer comprises a resilient cellular structure, the cells of which are closed and gas-filled, and is formed, during the shaping and curing of a green tyre in a mould, by the activation of a blowing agent contained within an appropriate material. Appropriate materials include natural and synthetic rubbers and their mixtures or blends, these materials being more precisely stated in the Specification, and suitable blowing agents are those which liberate gases such as nitrogen, or carbon dioxide. Agents which liberate CO 2  are typically ammonium carbonate and sodium bicarbonate, and examples of agents which liberate nitrogen are listed in the Specification. A preferred tyre was manufactured in the following manner: the tyre was built-up on a former (Fig. 1, not shown) and included a layer (5) of a compound comprising chlorobutyl rubber 100 (parts by weight), carbon black 50 plasticizer 20, sulfur plus accelerator 4, and N-nitroso compound-a heat activatable (blowing agent) 2. The green tyre blank was then shaped, moulded and cured in a mould at a minimum temperature of 92 C. The curing temperature activated the blowing agent to form a closed cell structure. The inner surface of the layer 7 may be covered by a liner (as illustrated).

Abstract: 754,173. Jet propulsion plant. SOC. NATIONALE D'ETUDE ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 12, 1954 [July 15, 1953], No. 20342/54. Class 110(3) [Also in Group XXXIII] A propulsion nozzle jet deflecting device comprises peripheral jet guiding means 10 outside -the normal jet path and controllable means for giving the jet a rotational velocity about the nozzle axis to urge it outwards centrifugally to encounter the jet guiding means, said controllable means comprising fluid injectors opening into the jet, forming a helical auxiliary jet acting on the main jet. In Fig. 1, a plurality of sets 6, 7, 8, 9 of circumferentially disposed slots act as orifices for inwardly directed jets of auxiliary fluid fed from a common manifold 3 supplied by a pipe 4 and valve 5, leading from a turbo-jet. or an auxiliary compressor. As is shown, the inclination of the slots to the nozzle axis increases progressively in a downstream direction, and the bores in the nozzle wall which form the slots are also inclined progressively more to the radial direction. The rotation imparted to the main flow makes it spread out radially to encounter the vanes 10. In Fig. 8, auxiliary fluid from a pipe 11 is tangentially injected into the space betwen surfaces 14 and 15, shaped so that the cross section of flow near the orifice is small, and the angular velocity of the fluid is thus increased. This fluid then acts on the main flow to set it in rotation. A further axial auxiliary jet may issue from pipe 17.

Patent GB-1149488-A (GB)
Title: Brake control
IPC: B60T8/32
Filed: 1966-05-09
Abstract: 1,149,488. Fluid pressure control of brakes; warning devices. RECHERCHES ETUDES PRODUCTION. 9 May, 1966 [10 May, 1965], No. 20464/66. Headings F2E and F2F. [Also in Division G3] The brakes of a vehicle are controlled by the use of at least three control signals, i.e. a first signal corresponding to the degree of braking desired by the driver, a second signal corresponding to vehicle speed and a third signal corresponding to the speed of a braked wheel, and a transducer which delivers to the braking members a pressure proportional to the difference between the sum of the first and third signals and the second signal. As applied to an aircraft, the transducer TR (Fig. 20) has three coils B 1 -B 3  which receive the signals and delivers a fluid pressure p to the braked wheel RF corresponding to the said difference. Coil B 1  is supplied from a pedal operated potentiometer 101 through the load conscious member 102. Generators Ge 1 , Ge 2 , driven by a free running wheel Pa and the braked wheel RF respectively provide signals of the vehicle speed and braked wheel speed to the appropriately connected coils B 2 , B 3 . On landing, wheels RF and Pa rotate at the same speed and the flux in coils B 2 , B 3  balance, the transducer producing no braking. When pedal PF is depressed coil B 1  is energized to apply the brakes, the consequent reduction of speed of wheel RF reducing the signal from Ge 2 , providing a " negative " flux from coils B 2 , B 3 . When the slip of braked wheel RF is sufficient the difference in signal between Ge 1  and Ge 2  across bridge 112 switches on amplifier 114, 115, which progressively reduces the current in coil B 1  by short circuiting the coil. At low speeds the current delivered by the generators is small and noise disturbs the regulation. To overcome this a fourth transducer coil B 4  is provided which is connected to a potentiometer 122 energized from the control potentiometer 101 to produce a negative flux in the coil. A diode 121 prevents the passage of a current which would produce a positive flux. To prevent the device working when the unbraked wheel is not rotating (e.g. when Pa is an aircraft nosewheel which has not yet contacted the runway) the generators are connected to a two winding relay 103, which interrupts the supply to the transducer unless both wheels are running and lights the indicator lamp 125. The Transducer (Fig. 21) comprises upper and lower blades 5, 7, connected by a shaft 8 and centralized by a torsion tube 11. When the coils B 1 -B 4  are de-energized the ends of the blade 5 are centralized in the air gaps of a permanent magnet circuit, one end of the lower blade being positioned opposite an orifice 13 fed through a filter 15 and orifice 14 from the hydraulic supply A. Variation of flux due to the coils B 1 -B 4  moves the upper blade in the air gaps and varies the distance of the lower blade end from orifice 13 to vary the pressure in chamber 22, control the position of valve 18 and thus vary the output pressure p.

Patent GB-206177-A (GB)
Abstract: 206,177. Shanklin, B. M. May 1, 1922. Ticket punches; tickets, issuing, registering value of.-A ticket issuing machine comprises the combination of a plurality of devices for marking the tickets, as by punching t'hem, to indicate fares and zones, any one of which devices may be set for operation independently of the remainder, a fare-totalizer, the extent of actuation of which is limited by means moved into limiting position by the setting of the marking devices, and a fullstroke device for ensuring correct actuation of the totalizer. The proper fare and zone punches 18f, 18z, Fig. 6, are struck by members 17f, 17<z>, on depression of a frame 16, all the members 17f, 17<z> being independently pivoted to the frame, as at 34, and to slidable members 36f, 36<z>, as at 35. Depression of selected fare and zone keys F, Z depress the corresponding slidable members 36f, 36<z> to set the proper members 17f, 17<z> in operative position. Depression of any fare key causes any other fare key already depressed to be restored, shoulders 38 on the members 36f engaging latches 45 to swing shafts 46 to free similar latches from the other members 36f being provided for this purpose. Similar arrangements are provided for the zone keys. Depression of the frame 16 is derived from a vertically reciprocating shaft 12, Fig. 1. This shaft also causes rotation of a horizontal shaft 13 in an anticlockwise direction, upon which shaft is loosely mounted a bell-crank 59, 61 and to which is secured an arm 15, which, on rotation of the shaft, pulls forward a frame 62 against springs 14. This movement permits a spring 60 to swing the bell-crank to actuate the totalizer R, through the linkage 58, 42, 55, 56 and gearing 51, 53. Depression of the selected fare-key puts a stop 65, Fig. 1, in the path of the swingable sector 55 to determine the extent of actuation of the totalizer. The stops are prevented from being swung out of the path of the sector by vertical guides 68, and the sector is provided with an overlying lip 66 to engage the stops. Spring-pressed catches 70, Fig. 2, engaging the stops normally to maintain the keys in the raised position are also provided. To ensure complete actuation of the totalizer corresponding to the depressed fare-key, the shaft 13 must be rotated in an anticlockwise direction a fixed amount before the springs 14 can restore it in a clockwise direction. To provide for this a ratchet wheel 75, Fig. 1, is secured to the shaft 13 and is engaged by a pawl 76 pivoted to a lever 77. After the shaft 13 has rotated a definite amount, a lever 27 rises and engages the lever 77 to free the pawl and to permit restoring of the shaft 13 and segment 55 to normal position. The connections between the shafts 12 and 13 and the lever 27, and the ticket slip-feeding mechanism form no part of the invention. Specifications 166,242 and 166,458 are referred to.
