Patent GB-2078415-A (GB)
Title: Fail-safe flame monitoring means
IPC: F23N5/24
Filed: 1981-06-18
Abstract: A flame monitoring means is arranged for selective use with an ionisation sensor (2) or a UV-sensor (3) which are connected in series with a first capacitor (7) to an a.c. voltage (U1). The sensor current charges up the capacitor (7). A threshold switch (74) provides for voltage-dependent discharging of the capacitor (7) and transmits the charge thereof partly to a second capacitor (15), and changes the charge thereof. The voltage thereof influences the input (19) of a trigger stage (42, 43, 44). An output switch (44) of the trigger stage short-circuits the supply circuit of a flame relay (34) in a temporally restricted permissible switching cycle. In the short-circuited condition, a capacitor (35) is discharged by way of the flame relay (34) which is then energised, and the subsequent charging current holds the flame relay (34) in an energised condition The output switch (44) also short-circuits a further capacitor (60) and, by way of a trigger circuit (56, 55), controls a flap (53) for masking the UV-radiation for a restricted period of time. Only the restricted UV-radiation permits the production of the permissible switching cycle, so that the flame relay (34) remains energised. <IMAGE>

Title: Aircraft undercarriage unit
Inventor: PUTNAM PETER MARTEN HERBERT
IPC: B64C25/58
Filed: 1982-06-11
Abstract: An aircraft undercarriage unit 10 comprises a main leg 11 which pivotally carries at its lower end a bogie beams 13 on which are mounted forward and rearward pairs of wheels 14 and 15 respectively. A variable length oleopneumatic strut 17 acts between leg 11 and a rearward portion of the bogie beam 13. The compression characteristics of the strut 17 are selected so that when the loading on the strut 17 and leg 11 are reduced as the aircraft approaches rotation speed at the end of a take-off run, strut 17 extends, causing the bogie beam to tilt, thereby effectively lengthening the undercarriage and thus increasing the maximum possible rotation angle for the aircraft. The strut 17 may be contracted after take-off to facilitate stowage of the undercarriage. Also applicable to an undercarriage unit having a single pair of wheels on a trailing beam (Fig. 5, not shown). <IMAGE>

Title: Submersible pump check valve
Inventor: LACRANGE NYLE DEAN
IPC: F04B53/10
Filed: 1982-09-15
Abstract: A valve element 30 for reciprocation within a port 12 has a body member which cooperates with a valve seat 28 defined on a wall around the port. A plurality of resilient legs 38 extend from the body member through the port and terminate in feet which extend radially beyond the periphery of the port. A central bore in the body member, parallel to the legs receives a locking stem 44 which reciprocates between a locked position and an unlocked position. In the locked position, a locking disc 46 on the stem engages projections 48 extending radially inward from the legs to prevent the legs from moving inward, thereby locking the valve element within the port. In the unlocked position, the locking disc is out of alignment with the projections, and bevelled surfaces on the feet cooperate with the wall to cam the legs inwardly, so that the valve element can be removed from the port when it is subjected to sufficient axial force. An annular ridge 56 on the stem cooperates with a resilient flange spaced from the body member to releasably retain the stem in its locked and unlocked positions. <IMAGE>
