Title: Improvements in or relating to liquid pressure remote control systems
IPC: F15B21/045
Filed: 1940-02-05
Abstract: 537,876. Hydraulic remote control systems. YORSTON, J., LANGLEY, T. W., and TECALEMIT, Ltd. Feb. 5, 1940, No. 2190. [Class 69 (ii)] In a hydraulic remote control system a dilatation compensator is associated with the control so as to balance the variation in the liquid capacity of the system due to change of temperature by a corresponding change in the volume of the liquid. in one form the system is connected by a pipe union to a screw-threaded socket 30 forming the upper end of the compensator which comprises a hollow spherical displacer member 1 formed of a low expansion alloy such as 36 per cent. nickel iron alloy. The displacer is supported in a metal sphere 2 formed of two parts screwed together and closed by a screw plug 8. The sphere is formed of an aluminium alloy of high thermal expansion and between the sphere and the displacer liquid is inserted which may be of the same nature as that of the hydraulic system. Above the sphere 2 is formed a cylindrical extension 9 with a stepped bore 10 and a connecting rod 13 slides in the bore and communicates the motion of a piston 11, which is displaced by expansion of fluid in the sphere 2, to a piston 19 of larger diameter which moves in a cylinder 16 fitted with a screw closure member 29 filled with the same fluid as the hydraulic system and connected thereto by the pipe union in socket 30. The piston 19 is fitted with a cup packing 20 and is pressed downwards by a spring 28. When the piston 11 is moved due to the differential expansion of the members 1, 2 and the liquid contained therein a corresponding movement is imparted to piston 19, but owing to the larger size thereof it can cause a compensation in volume in the hydraulic system which is greater than the differential expansion of the members 1, 2 and associated liquid. The piston 11 may be formed at its lower side with beaded edges which are pressed against the sides of a recess in the upper part of the sphere 2 by a screwed closure member formed with apertures to permit the compensating fluid to press on the lower side of the plunger. In a further modification Fig. 3, the screw closure member at the bottom of the sphere 2 may be arranged to receive a small amount of a liquid having a different expansion from that between the parts 1, 2, which is separated from the extra liquid by a diaphragm 40. The closure member 38 is fitted with a needle valve 42 normally fitted with a dust-excluding cap 44. The valve permits fluid to be inserted into the space 41 by means of a syringe.

Title: Ingition systems and fuel injection system for internal combustion engines
IPC: F02P3/045
Filed: 1972-01-18
Abstract: 1410782 Photo-electric engine control LUMENITION Ltd 10 Jan 1973 [18 Jan 1972] 2311/72 Heading G1A [Also in Divisions F1 and G3] In a system for electronically controlling the ignition or fuel injection in an I.C. engine, a first series of voltage pulses is generated in synchronism with engine revolutions, a second series of voltage pulse having a frequency greater than the first series is generated and provided to be counted by a counter from given instants in relation to the first series, so that the counter provides a high level output when a predetermined number of pulses have been counted, said predetermined number being variable in dependence upon the speed and/or load conditions on the engines, and means are responsive to detect the presence of both a high level output from the counter and from the means generating the first series and then provide the control. Control of ignition timing Figs. 2 and 3 A disc 3 having four apertures 9 and a large number of slits 10 is rotated by the engine crankshaft between a pair of infrared sources 5, 6 e.g. galluim arsenide lamps and a pair of phototransistors 7, 8, the latter being connected to respective trigger stages respectively having transistors 30a, 32a and 30b, 32b, so as to produce the first and second series respectively. The counter 14 receives the two pulses series and has the predetermined number set therein by a computer 16 which receives information regarding speed and/or load conditions on the engine. In operation, the trigger 30a; 32a produces a low output when an aperture 9 is between source 5 and transistor 7 and a high output at other times. When the level changes from low to high, the counter is set to count the pulses from trigger 30b, 32b. When the predetermined number has been counted, the counter provides a high level output to a switching stage, including transistors 50, 54, 56. When the transistor 50 receives this high output simultaneously with a high output from trigger 30a, 32a, the current flow through ignition coil 26 is interrupted to provide a spark. The photo-transistors 7, 8 may each be connected with another transistor to form Darlington pairs, Figs. 4 and 5 (not shown). Control of fuel injection Figs. 7 and 8 A disc 3 having a single aperture 9 and a large number of slits 10 is rotated by the engine crankshaft between infrared sources 5a, 6a, 5b, 6b and photo-transistors 7a, 8a, 7b, 8b connected as shown to trigger stages 11a, 12a, 11b, 12b and counters 14a, 14b, so as to provide two systems which operate 180 degrees out-of-phase to alternatively energize injectors 84a, 84b. The circuits 11, 12, 14, 18 are the same as in Fig. 3 except for the inter-position of an inverter between the transistor 50 and the trigger and counter. When the inverter receives simultaneously a high output from the counter and from the trigger, injection is initiated and is stopped when the output from the trigger returns to a low level.

Title: Improvements in or relating to aircraft instruments
Inventor: RUSSELL MICHAEL KING
IPC: G05D1/06
Filed: 1965-01-20
Abstract: 1,102,781. Measuring electrically. SMITHS INDUSTRIES Ltd. Jan. 14, 1966 [Jan. 20, 1965], No.2464/65. Heading G1N. An aircraft instrument derives a signal representative of the difference between a predetermined value a and the value of the function (α + b#) # being the pitch attitude and α the angle of incidence of the aircraft, and b being a positive constant. This signal is used to indicate how an acceptable flight path can be achieved, for example during an overshoot manoevre. It is stated that the maintenance of a predetermined value a for the quantity α + b# ensures an acceptable flight path. The difference a - (α + b#) may be indicated directly and reduced to zero by alteration of the pitch angle, or may be used to represent a desired rate of change of pitch, (D#) d . The signal (D#) d   is passed through a limiter to a summing amplifier where the actual rate of change of pitch is subtracted therefrom, to give an indication of the rate of change of pitch required to achieve the correct flight path, of gradient Y. Alternatively the demanded and actual pitch rates may be separately indicated on an indicator with two moving indices and the aircraft controlled to bring the indices together. In a modified arrangement, in which a - (α + b#) is indicated directly, the indication is provided only when required, by means of a switch, and an arrangement is provided whereby, when the switch is closed, the indication is registered gradually. This system includes a summing amplifier fed directly by the difference signal and also by the voltage on a capacitor charged by the same signal while the switch is open. When the switch is closed the output of the amplifier is zero but rises slowly to the full value of the difference as the capacitor discharges through a resistor. The switch may be actuated automatically in response to a sudden opening of the engine throttles. The value of constant a may be varied in both embodiments in accordance with the setting of the flaps of the aircraft. The value of the pitch-up demand signal (D #) may be increased at the beginning of an overshoot manoevre by injecting a transient signal to boost the value of a and then reducing this signal exponentially to zero. The device may be used to control the aircraft automatically.

Filed: 1972-01-21
Abstract: 1383252 Structural joints J VELUT 21 Jan 1972 [21 Jan 1971 25 Feb 1971 3 Nov 1971] 3068/72 Heading F2M [Also in Division E1] A beam, particularly for roof structures, of the kind which is formed by a metal sheet 12 held in bowed configuration by having its lateral edges engaged in sections, e.g. the sections 7, 8, which are held by cross-members 17 at a spacing less than the width of the sheet, is assembled by welding the sections to an assembly frame 9, providing converging guides 7a, 8a at one end of the sections, and drawing the sheet from a roll (15, Fig. 1, not shown) via a return roller 14 into the guides 7a, 8a, and thence into the sections, so that the sheet is progressively forced into the desired bowed configuration. For drawing the sheet a winch (13) is used, from which a cable 13a passes to anchorages on the forward end of the sheet. Preferably, the assembled beam is pre-stressed by anchoring the rear end of the sheet, after cutting from the roll, and applying tension to the forward end of the sheet by screwing nuts on to threaded rods welded to the sheet end until they bear with the desired force against abutment surfaces at the forward ends of the sections. A roof structure may be built up of a number of the beams arranged side by side. In such structure, adjacent sheets may share the same sections by using modified sections 21, Fig. 7, which have lips 24a, 24b flanking a slot through which the sheets are passed, the sections 21 being initially spaced such that drawing of the sheet bows it to a semicircular form, after which the sections 21 are moved apart so that the bowing is changed to a quarter-circular arc, whereby the sheets bear against the lips 24a, 24b to provide a seal. The modification of Fig. 9, employs half-sections 29, 30 interconnected by bendable tie-strips 31 such that initially gaps (27, 28, Fig. 8, not shown) occur between the half-sections to allow easy insertion of the sheet edges, then, after completion of the drawing of the sheet, relative longitudinal movement of the half-sections is effected whereby the tie-strips 31 become inclined and cause the half-sections to come together to grip the sheet.

[Class 110 (i).] Adjusting blades.-The blades of an electric ceiling fan are connected to toothed wheels which engage a worm on the main spindle so that the rake of the blades is varied as the fan rotates. The driving motor has a stator 3 on the fixed shaft 2 and a rotor 4 in a case 4 to which is attached a bowl casing 6 carrying the fan blades 8 on trunnions 20. A bracket 12 is secured to the inner boss 10 of the casing 6, and it supports bearings 13 for spindles 14 which have crank pins 15 at their outer ends engaging in bifurcated arms 18 on the trunnion caps 19. The inner ends of the spindles 14 carry worm wheels 16 which engage the worm 17 on the stationary shaft 2. The casings 6, 6 and the fan blades 8 rotate as a whole about the central axis, and as the wheels 16 travel round the worm 17 they rotate round their own axes. This causes the pins 15 to oscillate the caps 19 and the fan blades 8 so that the rake of the blades is slowly and continuously varied between limits.
