Title: Improvements in or relating to the controlling mechanism of aeroplanes
IPC: B64C13/00
Filed: 1933-10-26
Abstract: 419,687. Controlling aircraft. FAIREY, C. R., Cranford Lane, Hayes, Middlesex. Oct. 26, 1933, No. 29734. [Class 4.] Relates to control mechanism for aeroplanes of the kind in which means are provided for enabling the camber of the wings to be varied simultaneously in the same direction without interfering with the capability of varying the camber in opposite directions, e.g. as described in Specifications 135,520, 135,521, and 135,522, [all in Class 4]. According to the invention the means for varying the camber of the wings simultaneously in the same direction is interconnected with means for varying the angle of incidence of the tail - plane, such connection being capable of interruption so that the two variations may be effected either together or independently of each other. In the construction shown in Fig. 1, the incidence of the tail-plane 11 is controlled from a pulley 17 through cables 16, nut-drum 15 and threaded rod 14, while the camber of the wings is controlled from a pulley 18 through cables and a right and lefthanded threaded rod 19, the pulleys 17, 18 being disposed coaxially adjacent and associated with the handwheel 20 through clutches, either or both of which may be engaged to produce the result desired. In a modification, the cables 16, instead of being passed directly round the pulley 17, are associated therewith through the intermediary of a second pulley and screw and nut mechanism. In a further construction, Fig. 3, the right and left-hand threaded rod 19 that controls the camber of the wings has a threaded extension 29 on which is engaged a bifurcated non-rotatable yoke 27 forming bearings for a shaft 23 having a thread of equal pitch but opposite sense to the thread 29. By means of a pin and slot 32, 33 the shaft 23 is permitted to slide but not to rotate relatively to a sleeve 30, to which are secured a handwheel 31 and a pinion 35, the latter element being adapted to be thrown into or out of gear with a second pinion 36 on the' shaft by an intermediate or clutch pinion 37. The effective result is that if the pinions 35, 36 are declutched and the handwheel 34 is turned, both the camber of the wings and the incidence of the tail-plane are varied ; whereas, if the handwheel 31 is turned, only the incidence of the tail plane is affected. When the pinions 35, 36 are clutched and the handwheel 34 is turned, the camber of the wings is varied, but, owing to the differential action of the threads 23, 29, the incidence of the tail - plane is unaffected. Specification 417,898 also is referred to.

Abstract: 541,231. Supplying charge to engine cylinders. KADENACY, M., and ARMSTRONG WHITWORTH SECURITIES CO., Ltd. Feb. 14, 1940, Nos. 30055/39, 30353/39, 32695/39 and 32789/39. Drawings to Specification. [Class 7 (ii)] Gaseous charge supplied by a compressor to a reservoir is released into an engine cylinder or other receiver and therein trapped by a controlling valve before a return surge is set up, thereby obtaining a charge in the receiver at a substantially higher pressure than in the reservoir. It is stated that the higher pressure commences about 0.006 seconds after commencement of valve-opening and lasts for from 0.003 to 0.004 seconds. Charge may be supplied to an engine cylinder in two stages, inlet ports being served by two inlet ducts integral with the cylinder, each duct surrounding half of the cylinder, and being of decreasing cross-sectional area from its supply end towards its termination'. Separate reservoirs charged from a common compressor feed the two ducts. The compressor may be relieved from reservoir pressure oscillations by the interposition of a chamber having a non-return valve. The supply pipes and reservoir may be integral with or built into the cylinder-block, or the reservoir may be located beneath the engine. Specifications 431,856, 473,684 and 511,366 are referred to.

Title: Improvements in or relating to the production of cold
IPC: F25B27/02
Filed: 1933-10-30
Abstract: 428,058. Refrigerating. ELECTROLUX, Ltd., 153, Regent Street, London.-(Assignees of Platen-Munters Refrigerating System Aktiebolag; 2, Norrmalmstorg, Stockholm) Oct. 30, 1933, No. 30076. Convention date, Nov. 1, 1932. [Class 29] Cold-air and like non-condensing systems.- In a system in which cold is produced by the expansion of exhaust gases of an internalcombustion engine or by the expansion of air or other gas set in circulation directly or indirectly by the exhaust gases, the expanded cool gases exchange heat with the gases to be expanded. The exhaust gases may be led through an enlargement 1, Fig. 1, of the exhaust pipe to smooth out the delivery and are cooled in a gilled part 2 of the pipe and then expanded through a nozzle 3. The part 4 of the expansion pipe may be gilled for direct transmission of the cold, or may cool a secondary closed cycle heat transfer system, and the waste gases are passed through a heat-exchanger 6 to cool the gases prior to expansion. In another system, Fig. 2, the exhaust gases pass through an inducing nozzle 16 of an ejector 10 which draws atmospheric air through an expansion nozzle 14. The air thus cooled gives up its cold through the walls 16 of the expansion chamber 13, and is then led in heat exchange at 11 with the entering air. In another arrangement, the exhaust gases expand in a turbine 18, Fig. 3, which drives the rotary air compressor 19 of a closed circuit system having an expansion nozzle 24, and an interchanger 23. In this closed circuit air or heavier gases may be used. The above refrigerating system may be used on vehicles where refrigeration is also produced by utilizing part of the motor fuel in an evaporation system. The Specification as open to inspection under Sect. 91 comprises also the utilizaton of the exhaust gas turbine for driving the compressor of a condensing refrigerating system. This subject-matter does not appear in the Specification as accepted.

Title: Process of and system for regulating the operating behavaiour of an internal combustion engine
IPC: F02D21/08
Filed: 1975-07-18
Abstract: 1520427 Determining rough running in IC engine ROBERT BOSCH GmbH 18 July 1975 [19 July 1974 (2)] 30179/75 Addition to 1509075 Heading GIN [Also in Division G3] In an I.C. engine, the fuel/air ratio and/or the amount of exhaust gas fed back is controlled in response to the roughness (cyclic variations in speed) of the engine. The object is to operate with as lean a mixture as possible. In a first embodiment the crank-shaft carries two discs 10, 12, the first rigidly coupled and the second via a torsion spring element 14 of low natural frequency. Thus, the disc 12 rotates substantially smoothly at engine speed and angular differences occur between the discs due to the engine fluctuations which are detected by an inductive device 11, 13, 16. Pulses from this are applied to a logic circuit Figs. 5 and 6 (not shown) by which two capacitors are charged for a time equal to the angular displacement of the discs on two successive cycles respectively, and at a rate dependent on engine speed. The voltage difference between the capacitors is thus a measure of speed fluctuations (roughness) and this is compared with a reference (which may be dependent on speed, induction pipe pressure and/or engine temperature). The combustion mixture is progressively weakened by a ramp voltage produced by an integrater, but if the roughness signal exceeds the reference the integrator is inhibited so that the weakening is halted. In an alternative embodiment, Fig. 8, the signal corresponding to smooth rotation at engine speed is produced electrically. Pulses produced by a signal crank-shaft pick-up 11, 16 are squared and compared in phase at 115 with pulses at a steady frequency from a generator 116. The difference is  double integrated at 118, 119 and 120, 121, the resulting voltage corresponding to average engine speed being used to control the frequency of the generator 116. With this arrangement a second output of the comparator 115 occurs only when the engine speed departs from average, and for a time dependent upon this departure. This output controls a switching transistor 134 which allows a capacitor 131 to be charged while the output is present and at a rate determined by the speed dependent voltage via amplifying transistors 123, 124. Thus, the charge on the capacitor corresponds to the momentary angular displacement of the crank-  shaft, i.e. the "roughness" of the engine, and is compared with a reference voltage to control the combustion mixture as in the first embodiment.

Abstract: 1511522 Braking control for tractor-trailer combinations DAIMLER-BENZ AG 21 July 1975 [22 July 1974] 30433/75 Heading F2F Apparatus for regulating the braking force on the wheels of a towing vehicle/trailer combination 10, 11, in which respective independently controllable anti-locking braking force control systems are provided for the towing vehicle and for the trailer, by means of which systems each individual wheel is controllable in the stable region of the co-efficient of friction-slip curve, comprises a measuring means 20 disposed in the connection (e.g. tow-bar 15) between the towing vehicle 10 and the trailer 11 to ascertain the force occurring in said connection, the measuring means 20 being connected to transmit a signal to the anti-locking braking force control system of the towing vehicle when a predetermined compressive force in said connection is exceeded, upward adjustment of the braking force on the towing vehicle being blocked at least for the duration of the signal. This ensures that as the combination passes from a length of road having a low coefficient of friction to a length of road having a high coefficient of friction, an upward adjustment of the braking force on the towing vehicle wheels is prevented to thereby prevent jack-knifing. As seen in Fig. 2 an electronic part 17 of the control system of the towing vehicle 10 converts signals from sensors 18 on the front axle 13 and rear axle 16 into switch pulses to control valves 19 to control the braking force; the trailer 11 has a similar braking force control system but the two systems are independent. A threshold switch 21 is associated with the measuring means 20 and supplies a digital output signal to part 17 when the predetermined compressive force is exceeded. In one embodiment the threshold switch is connected by way of a matching amplifier and a filter. The threshold switch may also operate a timing element the running time of which may be reduced with increasing vehicle road speed. If the arrangement is utilized with a semitrailer unit, static fifth-wheel and trailer axle pressures are additionally measured.
