Title: Improvements in and relating to aircraft
IPC: B64C29/00
Filed: 1951-01-31
Abstract: 689,218. Aircraft. NAVICO. Jan. 31, 1951. [Feb. 1, 1950] No. 2428/51. Class 4. A fixed-wing aircraft is provided with adjustable flaps or other lift-increasing devices immersed in the slipstream of one or more pairs of variable pitch propellers which are tiltable in the pitching plane, the centres about which the propeller discs are inclinable being far enough in advance of the centre of gravity of the aircraft to ensure maintenance of equilibrium, in flight conditions in which a conventional stabiliser would be inoperative, by appropriate adjustment of the disc-inclinations and collective pitches of the propellers, and of the flaps or like devices. As shown, an aircraft is provided with slotted flaps 15, 16 at the rear of fixed wings 14, an inboard pair of tiltable propellers 50, 50b, and an outboard pair of non-tiltable propellers 62, 62b. The pitch of the propellers is adjusted simultaneously by a hydraulic jack 63 operating rods 36, 36a through members 60, 60b, 69 and 69b. Fore-and-aft movement of the control column 42 moves the elevators 45 through links 46 and tilts the inboard propellers 50, 50b through a bell-crank 47 and links 48, 55, 67, 67b, 34 and 34b in the same sense as the column is moved. Movement of the pedals 44, 44b operates the rudder 51 through cables 52, 52b, and through cable loop 53 and members 55, 67, 67b, 34 and 34b inclines the propellers 50, 50b in opposite directions Alternatively, the mechanism may be arranged to rotate the outboard propellers 62, 62b about vertical trunnions instead of tilting the inboard propellers. Operation of the hand-wheel 43 operates the ailerons 56, 56b through cable 57, 57b, and through cable loop 58 and members 66, 60, 60b, 36 and 36a increases the pitch of one outboard propeller and decreases that of the other to counteract changes of wing drag. If desired such differential pitch variation may be applied to all four propellers. Instead of mounting the propellers on trunnions for bodily tilting, the pitch of the blades may be adjusted cyclically by swash plate mechanism, Fig. 6 (not shown).

Title: Improvements in pulse width modulated bridge power amplifier with memory and lockout logic
IPC: H02P7/00
Filed: 1970-01-21
Abstract: 1,267,642. Control of D.C. motors. GENERAL ELECTRIC CO. 21 Jan., 1970 [28 Jan., 1969], No. 2891/70. Heading H2J. To control a servomotor 13 an input D.C. error signal is applied to terminal 37 and is mixed with a triangular reference voltage which is applied to terminal 36, the combined signal forming an input for level-sensing detectors 31, 32. The motor is supplied through bridgeconnected power transistors Q 1 -Q 4  which are associated with control transistors Q 1a -Q 4a . Due to the memory capability of NAND gates 61, 62, either one of the lower power transistors will remain conductive, for example the transistor Q 4 . Under these circumstances, the gates 61, 62, provide "1" and "0" outputs, respectively. When the output of both detectors 31, 32 is zero NAND gates 41, 42, provide "1" signals, whilst inverters 44, 49, provide "0" signals. Circulating current is passed from the motor through transistor Q 4  and diode D 2 . When the combined signal exceeds a negative threshold, the output of detector 32 goes to logic "1" at intervals dependent upon the strength of the error signal, whereby transistor Q 3  conducts and the motor is supplied through transistors Q 3 , Q 4 . During off-periods, coasting current is maintained through the elements Q 4 , D 2 . If the combined signal exceeds a positive threshold, transistors Q 1 , Q 2  become conductive so that the motor is reversed. The gates 41, 42 are interconnected to prevent simultaneous conduction of the power transistors Q 1 , Q 3 . A delay capacitor 68' prevents turn-on of the transistor Q 1  before transistor Q 4  turns off, thus ensuring that there are no transient bridge short-circuits. Zener diodes 64, 66, are effective when power is first switched-on to enable gates 61, 62, to establish their logic levels before transistors Q 2 , Q 4  are turned-on.

Paper tubes.-In a machine for making papercones from strip paper the paper is unwound from a roll 20 passed through a bath of adhesive 22 then through feed rollers 29, 30 and over an idle roller to a table 16 having an edge guide 17, and thence through further feed rollers 37, 38 to a cutting device 62; the severed blank is carried by a reciprocating gripper 105 to a conical mandrel 108 on which the blank is wound and its ends simultaneously cut after which it is discharged through an opening 148. The main driving shaft 18 is' driven through a pulley 19 the several parts of the machine being driven by gearing from the main shaft. The feed rollers 29, 30 are driven through a belt 35 from a shaft 33 which is driven through bevel gearing 34 from the main shaft Fig. 6; the feed rollers 37, 38 are driven intermittently and at a speed which rises to a maximum and then falls again, through an eccentric gear train 42, 43 and an interrupted gear wheel 39 on the shaft 33. The strip passes from the feed rollers to a sheet metal guide 47 by which it is guided to rest on lower cutting edges fixed to the machine bed, cutters 66, 67 are then oscillated during a rest in the feeding motion. and the cutters are so arranged that cutting commences at the centre of the strip and finishes at the edges. The front edge of one blank and the rear edge of the former blank are cut in one operation a complete blank being severed in two successive cuts. The cutters are oscillated by cranks 94, 97 on shafts 92, 93 respectively these shafts being rotated through bevel gearing from a cross shaft 88 driven through worm gearing from a shaft 85 which is rotated intermittently through a pinion and an interrupted gear 86 on the main driving shaft. The forward projecting edge of the severed blank now rests on a carriage 105 provided with a gripping jaw 106, this jaw being operated through a rod 110, crank 113 and gears 115, 116 from the shaft 85, the arrangement being such that after the blank is gripped the carriage is slid back on its track 107 by the rod 110 to place the edge of the blank in a slot in the taper mandrel 108. To avoid jar and! slip the mandrel is rotated intermittently slowly at first, rising to a maximum and then decreasing through an eccentric gear train 122, 123 and an interrupted gear 126 from the main driving shaft 18. At the time that the blank is wound a cutter frame 133 is spring pressed aginst the mandrel to train the ends of the blank and after cutting this frame is oscillated by pinion and sector gear 134, 136 and a cam' 140 to retract the cutters. After winding the blank transferring carriage 105 is again moved forward and a projection on it contacts with the wound cone and removes it from the mandrel.
