Title: Increased lift wing profile - having raised upper flap on front of profile and hinged flap spaced from rear
IPC: B64C21/04
Filed: 1973-12-17
Abstract: The lift of the wing profile is increased in a simple, effective way with the front, top leading edge of the wing lifted at its rear end, pivoted about the leading edge of the wing.

Further advantage can be obtained by trailing flaps pivotted behind the wing edges at some spacing from them. Even more lift can be generated by auxiliary surfaces above the leading flap and trailing edge.

Title: Controlled rest chamber for dough before cooking - with extended helicoidal track and articulated conveyors
IPC: B65G21/18
Filed: 1975-05-23
Abstract: Pieces of dough, after division in a corresponding machine, are given a rest period for a definite time before cooking so that the bread will have the required quality. The rest chamber consists of a structure with different levels and a plane, helicoidal track so that a long route is provided in a small space for the carriages holding the pieces of dough. The latter are carried in a continuous chain of circular or polygonal conveyors, articulated together by means of open hooks, and mounted on small wheels to guide them on the track. They are driven by a motor and pulleys. The conveyors are each in two parts with a lower hinged portion; this falls away, under the action of a fixed stop, to release the dough when it reaches a certain point over an opening on the track. The rest period is controlled by simple means before the dough goes to the oven.

Title: Vehicle navigation system retracing previous journey - uses recording system in vehicle and fixed set of beacons
Inventor: VIRNOT ALAIN
IPC: G01S5/02
Filed: 1975-07-11
Abstract: At certain points on the trajectory, the information provided by two or more beacons is recorded. During a subsequent journey, similar information is detected from the same beacons. From this information and pre-recorded information related to a known point on the trajectory, near the actual position of the vehicle, the transverse and longitudinal deviations of the vehicle's actual position w.r.t. the known point are calculated. The associated equipment includes a memory (6), a detector (1) giving the vehicle's position w.r.t. the beacons, and a computer. The computer calculates, for each beacon used, the equation of a straight line. It then determines the vehicle position from the intersection of two such straight lines, either by minimization of the sum of the squares of the distances between the vehicle and several lines.

Title: Vehicle flashing direction indicator switch - has pivoting connection with pawl locating device and sliding main operating block
Inventor: WILKINSON NORMAN
IPC: B60Q1/42
Filed: 1976-01-09
Abstract: The operating lever (13) is hollow and carries the switch indicator on its end. There is a central rest position and two angular operating positions the two pivoting axes being 14 and 15. Helical springs tend to retain the central operating block in the mid position. Pawls (16, 17) with triangular cross section point outwards to the sides of the casing and as the operating arm is moved these locate over ridges or bosses (21, 22) on the casing. The pawls are supported by pegs (18, 19) fitting in oval recesses in the operating block and the effect of the pivoting movement is to slide the operating block down the casing altering the switch contact point (24, 25).
