Title: Nozzle gap supporting plane
IPC: B64C21/08
Filed: 1933-07-03
Abstract: 414,209. Controlling aircraft. KSOLL, J., 22, Enderstrasse, Breslau, Germany. July 3, 1933, No. 18854. [A Specification was laid open to inspection under Sect. 91 of the Acts, Jan. 3, 1934.] [Class 4.] A flap or aileron capable of being moved rearwardly and tilted relatively to the fixed part of an aircraft wing, so as to form a nozzle gap between the fixed part and the aileron or flap, is supported by a sliding pivot or a system of pivoted links arranged so that the flap or aileron has a motion compounded of a translation and a rotation. An aileron or flap II, Fig. 2, is pivoted about a pivot 1 capable of being moved along a slot 10 by a link 8 and lever 9 until it is in the position II<a>. A gap is thereby opened between the plane and the aileron or flap, but it is ineffective until the aileron or flap is tilted by a link 2 and lever 4 in order to produce a positive pressure at the lower end of the gap. Further tilting of the aileron or flap II does not widen the gap. Fig. 3 shows a modification in which the flap II is carried by parallel links 15, 16 hinged to a lever 12, 13 pivoted at 11 to an arm 7 on the planes. The lever 12, 13 is normally held by a spring against a stop 14 so that the flap first moves from the position II to a position II<a> as the lever 4 is actuated. Further movement of the lever 4 causes the lever 12, 13 to tilt owing to the link 15 being incapable of further angular movement relative to the lever 12, 13. Two other similar linkages, but involving non-parallel links, are described which cause an immediate tilting of the flap as well as a translational movement. In one case the gap is kept closed during the initial movement by the flap remaining close against the upper rear edge of the fixed part of the plane. In the other case the lower end of the gap is kept closed by a plate 18, Fig. 4<a>, urged upwards by a spring when the flap reaches the position II<b>. The plate is returned to its normal position by a cam plate 22 on a rod 20 connected to the lever 4 and having a slot 21 moving over the pivot 17 of the plate 18, the plate 22 engaging a projection 19 on the plate 18. Another linkage is described having for its effect a continual widening of the gap as the aileron or flap is tilted. Fig. 7 shows a modification in which an independently operable braking flap 22 is mounted beneath the aileron or flap II. This flap 22 is normally kept against the flap II by a rubber or other spring 23 and is connected by a cable 26 to a spring drum 29 on a lever 30. As the flap II moves rearwardly the cable 26 unwinds from the drum 29 until the flap II is in its extreme position and the drum 29 can not rotate any further. Movement of the lever 30 then causes the depression of the flap 22 as shown at 221. A telescopic linkage may replace the cable 26 and spring-drum 29. According to the Specification as open to inspection under Sect. 91, the invention may be applied to elevators. This subject-matter does not appear in the Specification as accepted.

Filed: 1975-07-30
Abstract: 1516971 Electric analogue multipliers POST OFFICE 30 July 1975 [30 April 1974] 18942/74 Heading G4G An electric analogue multiplier comprises a first pulse modulator 2 receiving a first-input signal at 1 and producing at its output a first rectangular pulse train at a first repetition frequency F 1  and of width dependent on the amplitude of the first input, a second pulse modulator 7 (similar to 2 in details) responsive to a second input at 6 to produce a second rectangular pulse train at a second frequency F 2  (F 2  # F 1 ) with pulse width dependent on the amplitude of the second input and an exclusive OR gate 4 the output of which, when smoothed, is shown to be representative of the product of the two inputs. A further pulse modulator 9 receiving the same input as generator 7 but with a #/2 phase difference produces a further train of pulses at frequency F 2  which is applied with the output of modulator 2 to a further exclusive OR gate 5. The outputs A, B of gates 4 and 5 are then fed to a circuit which generates #A<SP>2</SP> + B<SP>2</SP> or, as shown, a circuit 13 deriving an approximation to this, namely ¢ (A + B + greater of A and B), the circuit then constituting a correlation circuit for determining the correlation between the inputs at 3 and 6. The circuit can be used to determine the component of this frequency in a complex input signal applied to 1 by applying a fixed frequency F 1  signal to 6. Fig. 3 indicates how further channels may be added by means of modulating 21, 23 and gates 24, 25. In the circuit 13, digital amplifiers 50, 51 and 67, 68 are pairs of opposing polarity gain. Resistor-capacitor combinations such as 53, 54 are integrators and back-to-back diodes such as 55, 58 determine the greater of A and B and pass the appropriate signals to a summing amplifier 57.

Abstract: 940,330. Motor vehicle transmission gearing. EATON AXLES Ltd. May 17, 1962 [June 1, 1961], No. 19038/62. Heading B7H. [Also in Division F2] In a vehicle transmission comprising two multi-speed axles 11, 12 connected in tandem through an interaxle differential 73 the driving ratios of the two-speed epicyclic gears sets (Fig. 3) incorporated in each axle are separately selectable by a control system (Fig. 5) to provide three different transmission ratios, i.e. with both axle gear sets in low ratio, with one gear set in low ratio and the other in high ratio, or with both gear sets in high ratio. The gear set 14 of the axle 12 includes a crown gear 22 formed with internal teeth 34 meshing with planet gears 29 on a carrier 23 driving halfshafts 24, 25 through differential gearing 27, 28. A sun gear 32 meshing with the planet gears 29 is carried by a sleeve 33 which is axially displaceable between a low ratio position wherein the sun gear 32 is held stationary by engagement of teeth 36 on the sleeve with teeth 37 on a housing 18 and a high ratio position wherein the sun gear engages teeth 38 on the carrier 23. Ratio selection is effected by an air pressure cylinder 44 actuating a lever 40 resiliently connected through torsion springs (Fig. 6, not shown) mounted on a shaft 42 to a fork 39 engaging the sleeve 33. A similar epicyclic gear set 13 on the axle 11 is provided with a crown gear 53 (Fig. 2) and an air pressure cylinder 107 (Fig. 5). The interaxle differential 73 comprises input bevels 59 carried by a ring 74 secured to an input shaft 55 and output bevels 72, 75 respectively connected by gears 69, 68 to a pinion 19 driving the crown gear 22 and by a shaft 57 and a connecting shaft 58 to a pinion 52 driving the crown gear 53. A dog-clutch 79 splined to the input shaft 55 may be engaged with the gear 69 to prevent differential action between the axles 11, 12 by an actuator 136 linked to an air pressure cylinder 134. For lubrication purposes a housing 56 enclosing the differential 73 is formed with a trough 83 which supplies oil thrown thereinto from the gear 69 to the differential through a passageway 84 and openings formed in the shafts 55, 57. As shown in Fig. 5 springs 104 acting on the levers 40 normally retain the gear sets 13, 14 in low ratio until compressed air from a source 103 is supplied to the cylinders 44, 107 to select high ratio through solenoid valves 112, 114 energized by a selector switch 137 which may energize the valve 114 alone or both valves 112, 114 together. When the gear sets 13, 14 are in low ratio so that contacts 166, 167 associated with one lever 40 are closed the dog-clutch 79 may be engaged to lock the differential 73 by closing a switch 162 to open a solenoid valve 132 which supplies air to the cylinder 134 and also to a pressure responsive switch 151 which isolates the selector switch 137 to prevent high ratio selection while the differential is locked.

Title: Improvements in means for regulating combustion in boiler furnaces
IPC: F23N5/02
Filed: 1928-07-03
Abstract: 318,699. Wingfield, B. T. July 3, 1928. Thermostats.-In the thermostatic regulation of combustion in heating- plant boilers, two helical Bourdon tubes are employed, one responsive to the outside temperature, the other to the temperature or pressure of the boiler. As illustrated, the Bourdon tubes 3 and 10 are connected respectively to an out-of-door bulb 1 and a bulb 8 in the hot-water flow from the. boiler. Tube 3 carries a. forked arm 4 with electric contacts 5, 6 and, as viewed in the Figure, uncoils anti-clockwise on increase of temperature; tube 10 carries a contact arm 11 having a, limited free movement between the contacts 5, 6 and uncoils clockwise. Contact made at 5, due to rise of either the outdoor temprature or the boiler temperature, closes the boiler damper; similarly contact at 6 due to fall of temperature opens the damper. Thus, over the range of outdoor temperature provided for, the boiler temperature is appropriately controlled. The adjustable stop 7 puts a limit to the rise of boiler temperature on decrease of outdoor temperature. In the case of a steam boiler, the Bourdon tube 10 may be actuated by steam pressure. Instead of a damper, the oil or gas fuel supply or a circulating fan or pump may be controlled.
