Title: Improvements in and connected with the regulation of super-charged internal combustion engines, particularly aircraft engines
IPC: F02D29/00
Filed: 1939-03-21
Abstract: 511,930. Fluid-pressure servomotor-control systems. DAIMLER-BENZ AKT.-GES. March 21. 1939, No. 8938. Convention date, March 24, 1938. [Class 135] [Also in Group XXVII] In supercharged engines, particularly of aircraft, wherein two working factors are positively varied by a manual control, one factor (e.g., changing pressure) being dependent on atmospheric pressure and also upon the other factor (e.g., speed) means are provided whereby, when the atmospheric pressure falls too low to maintain the first factor, the second factor is adjusted so as to restore the first to its desired value. The Figure shows a pilot's control lever 17 connected (a) to a capsule 21 which is subjected to the changing pressure of a blower 12 and controls a throttle 14 in the blower discharge by means of a servomotor 24, 27, and (b) to the sleeve 11 of a centrifugal governor 8 controlling the pitch of the propeller blades 4. Adjustment of the lever 17 from A to D displaces the capsule 21 to increase the blower pressure, and at the same time adjusts the sleeve 11 to increase the load on the governor and thereby the speed. When atmospheric pressure becomes decreased at altitudes, the changing pressure of the blower falls below the prescribed value, and to restore the changing pressure an aneroid 31 is provided which, under such conditions, contracts the toggle linkage 28, 29 so as to increase the speed of the engine and therefore also of the blower. When the lever 17 is in the idling position A, it contacts with a lever 18 connected to an idling throttle 15. At the position B, the lever 18 is prevented from moving farther by a stop 19, the throttle 15 being then fully open. When the lever 17 is moved beyond the fulloutput position D for starting, a further lever 40 is actuated to increase the fuel supply by means of a connection 42, 38 to the fuel pump 16. This pump is also under the control of a piston 36 acted on by the changing pressure. In a modification, the lever 17 is also connected to the aneroid 31 so as to displace it bodily; an adjustable arm may be introduced between the lever 17 and the aneroid. A relay may be provided between the linkage 28, 29 and the governor. Also cams may be provided between the control lever 17 and the connections to the blower and governor controls, so as to vary the relative adjustments of each.

Title: Improvements in and relating to grating spectrometers
Inventor: MARTIN ALBERT EDWARD
IPC: G01J3/18
Filed: 1957-03-19
Abstract: 861,639. Infra-red monochromators. GRUBB PARSONS & CO. Ltd., Sir H. March 7, 1958 [March 19, 1957], No. 8986/57. Class 97(1) In order to avoid superposition of spectra of different orders, the radiation in an infra-red monochromator is dispersed by one or more echelette gratings, at least one of which is such that the diffracted radiation therefrom lies on the same side of a normal to the surface of an individual groove as the incident radiation, and the smaller of the two angles made by the incident and diffracted radiation with said normal has a value in degrees greater than #N/5000 where # is the first order wavelength to which the grating is set and N is the number of lines per inch on the grating. In one form, Fig. 4, radiation from entrance slit S 1  is collimated at C and diffracted by echelette grating G, so that the diffracted radiation returns to mirror C and is focused thereby on exit slit S 2 , whence it is directed by mirrors M 2 , M 3  on to detector D. Before passing to the exit slit S 2 , the diffracted radiation from mirror C may in another embodiment be doubly reflected back on to the mirror C, and diffracted again at G. In a further form, Fig. 6, radiation from entrance slit S 1  after collimation at mirror C 1  is successively diffracted by echelette gratings G 1  and G 5  before being focused on exit slit S 2 . In order to vary the first order wavelength, the five gratings are linked together for simultaneous rotation. Two or more grating spectrometers of the above kind may be combined in series, a single slit acting as exit slit for the first monochromator and as entrance slit for the next monochromator. The arrangement may be employed in an infra-red spectrometer or gas analyser.

Title: Improvements in and connected with Internal Combustion Engines especially for Use on Aircraft.
IPC: F01P5/12
Filed: 1917-06-23
Abstract: 127,911. Leyland Motors, Ltd., and Thomas, J. G. P. June 23, 1917. Cooling lubricant. - The crank -shaft and cranks and lubricating- pipes of an internal-combustion engine for aircraft &c. are cooled by pumping through them a fluid distinct from the lubricant. A continuous pipe 7, 17, 18 is centrally spaced through the hollow shaft, crank-pins and crank-webs. A rotary pump 9 mounted on the end of the shaft draws water or other fluid through an opening 11; the water passes along the length of the shaft in the space surrounding the pipe and enters the end of the pipe, through which it passes to the pump. The end of the pipe remote from the pump is made trumpetshaped to engage the inner surface of the shaft, and holes are provided for the passage of the water. Lubricant is supplied to the crank-pins through pipes 43, 44 placed in the stream of cooling-fluid. Further cooling of the lubricant may be effected by passing it between helical fins formed on an extension of the crank-shaft, which provide a large cooling-surface.

Title: Improvements in and relating to Alternating Current Dynamo Electric Machines.
IPC: H02P9/12
Filed: 1918-06-01
Abstract: 129,068. British Thomson - Houston Co., Taylor, H. W., and Whitcher, J. June 1, 1918. Dynamos, regulating; auxiliary protective or safety devices.- When a fault occurs, the exciter field of an alternator is reversed, and the exciter current is shunted. Normally, the field 1 of the exciter 6 is in series with resistances 2, 4. When a fa.ult occurs, the switch 5 closes under the action of a spring to reverse the direction of the current in the exciter-field 1 and to connect the resistances 2, 4 in parallel across the exciter terminals. By means of an additional contact 7, the switch 5 short-circuits a rheostat 3 in series with the exciter-field 1. Alternatively, a doublethrow switch is employed, and the resistances 2, 4 are normally short-circuited, but are connected in parallel across the exciter terminals when a fault occurs.

Title: Improvements in pressure-actuated flow control valves
IPC: B64D13/02
Filed: 1965-03-03
Abstract: 1,048,417. Valves. INTERCONTINENTAL DYNAMICS CORPORATION. March 3, 1965 [March 12, 1964], No. 9165/65. Heading F2V. [Also in Division G3] A control valve for regulating the pressure in an aircraft cabin comprises a grill-like seat member 25 mounted in a port 33 in the cabin wall 11 and having arms 30 carrying a housing 20 and co-operating therewith, with the interposition of a ring 23, to locate the periphery of a diaphragm 15 having a thickened central portion 16, the diaphragm defining one wall of a chamber 18 connected via conduit 60 and cock 62 to a port 45 in the cabin wall, via bleed orifice 36 with the cabin, and via a port 48 with a chamber 40 having a connection via conduit 44 with the orifice 45. One wall of the chamber 40 comprises a diaphragm 41 carrying a pilot valve member 49 urged by springs 52, 52a to close the port 48, the diaphragm being acted upon on its other side by cabin pressure in a chamber 39 communicating with the cabin via port 42. A disc 54 limits travel of diaphragm 41. In operation, when the cabin is pressurized air flows through annular space 31 to create a lower pressure on the outer face of diaphragm 15 and allows the higher cabin pressure in chamber 18 to move the diaphragm to seat against the ports 27, 29 in the valve seat 25. Should the cabin pressure exceed the outside pressure by more than an amount predetermined by spring 52, the diaphragm 41 moves to unseat pilot valve 49 to vent chamber 18 and thereby permit the pressure acting on that part of diaphragm 15 in space 31 to unseat the latter. Should the outside pressure ever exceed the cabin pressure it will unseat diaphragm 15 by acting over the central external portion thereof. If it is required to depressurize the cabin, cock 62 is open to vent chamber 18 to thereby open the main valve. In the alternative embodiment of Fig. 4 (not shown), the valve is mounted on the outside of the cabin. By employing a different type of pilot valve (type unspecified) the valve may be used to maintain a desired absolute cabin pressure by controlling release of air from the cabin. The diaphragm is biased to the position shown, but in an alternative embodiment the co-operating face of the seat member may lie in the same plane as the closure face of the diaphragm, thereby constituting a normally closed valve.

Title: Mechanical-hydraulic speed gear with continuous automatic or regulated variations of the gear ratio
IPC: F16H61/02
Filed: 1932-03-30
Abstract: 403,930. Variable-speed gearing. TALIANI, T., 203, Via Cola di Rienzo, Rome. March 30, 1932, No. 9189. Void [Abridged as open to inspection under Sect. 91 of the Acts, Aug. 6, 1932]. [Class 80 (ii).] Relates to variable-speed gearing in which two elements of an epicyclic train are connected to driving and driven shafts respectively and the third or reaction element to a liquid reciprocating pump brake controlled by a throttle so as to vary the range of automatic speed ratio. The object is to eliminate impulses in the drive. The reaction element shaft R, Fig. 2, carries eccentrics E, E<1>, in cross-heads which reciprocate pump pistons F, F<1> which draw liquid such as oil from a common chamber 3 and deliver it to a common chamber 4. The pistons are in different phase so that by connecting the chambers 3, 4 by a single hydraulic bridge or duct 5, impulses are in part cut out. A control throttle valve is shown at 6. Making the eccentrics E, E<1> in the form of cams of heart shape further reduces the impulses. An auxiliary system 7, 8 replenishes the enclosed oil Residual impulses in the liquid are compensated by superposing artificial impulses, and such an arrangement is shown in Fig. 4. A branch chamber 18 in parallel with the valve 6 is enclosed by a partition 19 through which slides a plunger 20 reciprocated from a multiple cam S on the shaft R. The plunger 20 is set to rise to damp out an increased impulsive pressure below the valve, and so on. Other arrangements of damping pistons are described.

Title: Improvements in or relating to spacers for overhead electric transmission lines having bundled conductors
Inventor: COX JOHN EDWARD
IPC: H02G7/12
Filed: 1962-03-09
Abstract: 954,710. Cable spacers. BRITISH INSU LATED CALLENDER'S CABLES Ltd. March 11, 1963 [March 9, 1962], No. 9266/62. Heading H2C. A spacer for bundled conductors comprises two or more rings, each carrying an arm which terminates in a conductor clamp, the rings being resiliently maintained in axial alignment and restrained from axial rotation relative to each other, the axes of the clamps being parallel to one another but at right angles to the axis of the rings. As shown, a spacer for a cable having three component conductors comprises three rings 1, 2, 3 spaced apart by neoprene washers 7 and 8 mounted on a spindle 4 which also carries end-plates 9 and 10 spaced from rings 1 and 3 by neoprene washers 11 and 12. Projecting from the rings are arms 13, 14, 15 carrying conductor clamps 16, 17, 18. The friction grip between the neoprene washers and the rings is such that any relative rotation of the rings about the spindle 4 is accommodated by distortion of the washers. Since a small clearance is left around the spindle slight movement in a plane containing the arm and the spindle axis is permitted, this again is accommodated by distortion of the washers. Any movement perpendicular to the conductor is limited by bell-mouthing each end of the clamp, 19, 20 (Fig. 2, not shown), or by providing a layer of resilient material between the conductor and the embracing wall of the clamp. Ina further embodiment the spindle may have a sleeve or covering of resilient material, each ring being secured to this resilient sleeve by bonding, cementing, friction, or by making the spindle and ring of non-circular cross-section. To produce a good friction grip between the ring and the resilient sleeve each ring may be split diametrically or radially into two or more parts which are screwed together. The rings may comprise an outer and an inner rigid ring united by an intervening ring of resilient material, the inner rings may also be coupled to or integral with each other and form a common support with or without a spindle. A natural or synthetic rubber composition may be used as resilient material. Spacers for bundles of four conductors and two conductors are also shown.
