Title: Improvements in or relating to turbine-driven compressors
IPC: F01D25/18
Filed: 1957-03-27
Abstract: 823,581. Turbines; centrifugal compressors. BUCHI, A. J. March 27, 1957 [April 14, 1956], No. 10001/57. Classes 110 (1) and 110 (3). In a turbine driven compressor in which the turbine rotor 1 and compressor rotor 2 are carried for rotation about a fixed mounting 3 extending at least in part into hub portion of the compressor rotor, both rotors being supported by a single tubular rotor shaft 5, the rotor assembly being secured to a support member 5a of the shaft 5, with a central member 13 connected to the turbine rotor extending through the rotor shaft 5, the central member 13 has a solid portion adjacent the turbine rotor and a larger diameter tubular portion 6<1>, which extends in part within the rotor shaft and is supported therefrom, at the end remote from the turbine rotor. The rotor shaft 5 and the central member 13 define an annular passageway 6 which communicates with the tubular portion 6<1> to form a main lubricating and cooling oil passage. Oil is supplied to the portion 6<1> and the excess passes through the passage 15 and chamber A into the drain pipe 21. The remainder passes through the portion 6<1> to ports 6a where part is supplied to the thrust bearing 10. The remainder passes into the channel 6 where part passes to the radial bearings 9, 9<1>. The remainder passes through passages 6e to an annular channel 14 and passages 14a to the space 4a. This oil cools the support member 5a. The oil from the bearings 9, 9<1> also flows into the space 4a from whence it passes through chamber 8 to the drain 21. The oil from the thrust bearing 10 also flows into the chamber 8. The turbine and compressor rotors are attached to the shaft 5 by the member 13 carrying a clamping nut 19 which forces a sleeve 18 against one member of the thrust bearing 10. The other member of the bearing 10 is held in position in the member 3 by a screw cap 17. The area of the passages 14a is selected so that sufficient oil is supplied to cool the member 5a whilst maintaining the pressure at the bearings.

Abstract: 513,320. Electric signalling systems. BRITISH THOMSON-HOUSTON CO., Ltd. April 1, 1938, No. 10051. Convention date, April 2, 1937. [Class 40 (i)] In a resultant field system particularly employing light moving coil rotors for transmitting compass indications, reaction of the receiver or receivers on the transmitter and during frictional effects movement of the transmitter are avoided by periodically disconnecting the transmitter rotor and, if desired, the receiver rotors, from the supply wires, the transmitter rotor being held during transmission. As shown, transmitting and receiving single phase rotors 12, 22, connected to a compass needle 14 and indicator 24 respectively, are adapted to be fed over brushes 13, 23 and slip-rings from supply 3, inter-connected three phase stations 11, 21 being employed as usual. The brushes 13 are normally out of contact with the slip rings and are engaged therewith by magnet 32, Fig. 2, this action serving also to hold the transmitter. The supply 3 is preferably of highfrequency or peaky wave form and is also periodically interrupted at low-frequency and applied to the magnets 32 to cause periodical engagement of the brushes with the slip rings. The high-frequency source may be a condenser charged up and then discharged over the supply wires by means of a commutator which also interrupts the high frequency at a low frequency for periodical energisation of magnet 32. The resulting wave form may be as shown in Fig. 3a. Alternatively, a two-grid relaxation oscillation generating tube may be used, one grid providing for high-frequency oscillations and the other being used to give low frequency interruption thereof.

Title: Improvements relating to aircraft controls
IPC: B64C9/20
Filed: 1942-07-21
Abstract: 558,046. Controlling aircraft. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., Sir W. G., and LLOYD, J. July 21, 1942, No. 10160. [Class 4] An aileron or flap at the trailing edge of another aerofoil is guided by a projection thereon engaging a cam surface fast with the aerofoil and is also linked to the aerofoil, the cam surface being so shaped that when the aileron or flap is in its neutral or uptilted position there is no slot between it and the aerofoil but when moved in the other direction its leading edge separates from the aerofoil to provide a slot. The wind pressure assists the movement of the flap during its passage from the neutral to the extreme rear position. As shown, an aileron 18 is normally nested with its forward upper surface beneath the trailing edge of a flap 13 mounted as described in Specification 558,043. A point 30 on the aileron is connected by a link 27 to a bracket on the flap and a projection 31 on the aileron moves in a cam slot formed in a plate 32 secured to the flap. From the neutral position to the extreme uptilted position the projection 31 moves in a part 33 of the slot concentric with the point 30 which remains stationary. From the neutral position to the extreme rearward and downward position the projection 31 moves in a part 34 of the slot and the link 27 swings about its upper end thus causing a slot to open between the aileron and the flap. The aileron is moved by a link 25 connected to a point 26 on the aileron and to a bellcrank lever 24, Fig. 3, linked to an arm 21 pivoted at the junction of a projection 14 on the flap and a link 15, the arm 21 having a sprocket coupled by a chain 22 to a sprocket on another arm 20 at the other end of the link 15 where the latter is pivoted to the main wing.

Abstract: 1,133,251. Automatic temperature control systems. PIONEER ELECTRIC (BRANDON) Ltd. March 8, 1966 [March 8, 1965], No.10194/66. Heading G3R. [Also in Division H1] In a temperature control system for a room in which a snap-action switch 3 is operated by a bi-metallic element 4 which senses the air temperature and is disposed near to the switch 3, a heat shield 6 is disposed between members 3, 4 to reduce the variation in the control point caused by the response of element 4 to the heat generated by the switch 3 during long periods of energization of the heating load. The surface of shield 6 facing the switch 3 is heat reflective and members 3, 4, 5, 6 are chosen and positioned so that the aforementioned variation is reduced to a minimum, the resistor 5 providing an anticipation effect to prevent overshoot of the desired temperature. The switch 3 may be shunted by another resistor (7) Fig. 2 (not shown) which generates heat when the heating load is de-energized and thus further reduces variation in the control point between the energized and de-energized conditions of the load. The system may be used to control cooling equipment in which case the resistor 5 is replaced by a thermo-electric cooling element.

Title: Improvements relating to indicating apparatus for radar
IPC: G01S1/02
Filed: 1947-04-17
Abstract: 632,228. Photo-electric control of radar transmitter. MILLER, C. W., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 17, 1947, No. 10242. [Class 40 (iii)] [Also in Group XL (c)]. Apparatus for displaying the echoes arriving at a radar receiver 4 comprises a light source 6 adapted to be modulated by received echoes, together with a rotatable reflector 9, mounted on a carrier 14 which is movable in accordance with the angular positioning of the aerial 1 by means of gearing 11. The light source 7 is continuously illuminated to produce a beam which strikes the light cell 8 at a predetermined position of the reflector 9 and causes the cell to trigger the pulse generator 5, thus synchronizing the presentation on the screen 10 with the pulses from transmitter 3. In the preferred embodiment a plan position indication is given by rotating the carrier 14 so that the substantially linear sweeps from the reflector 9 rotate about a central point on the screen 10, but if the speed of rotation of the reflector 9 is small compared with that of the carrier, a spiral time-base may be obtained. In the embodiment of Fig. 3 (not shown) the base-plate 14 is mounted in a cage framework constituted by annular end rings interconnected by longitudinal rods, each end ring being circumferentially carried by three equi-spaced rollers mounted in a static framework. The cage is rotated to produce a P.P.I. presentation by means of a pinion driven from the aerial and engaging with teeth on the interior of one end ring. Alternatively the linear trace may be moved laterally to produce a type-B scan. The aerial may be connected through remote control, e.g. Selsyn or magslip transmission, and the light source may be infra-red or ultra-violet in which cases a fluorescent screen is required. The light source is normally modulated in a known manner to produce a beam or increase its intensity when an echo is being received, but a dark picture on a light ground may be obtained by reducing the beam intensity when an echo is being received.

Title: Improvements in or relating to the superposition of signals on electrical communication systems
IPC: H04J1/00
Filed: 1943-06-24
Abstract: 587,447. Transmitting music &c. RANTZEN, H. B. June 24, 1943, No. 10244. [Class 40 (iv)] A narrow frequency band is removed from a wide-band main signal (e.g. speech or music), and an auxiliary signal is conveyed by a tone within said narrow band, the tone being broken up into Morse or like elements and kept at a relatively low volume, so that it is practically inaudible when the combined signals are converted into sound, but can be isolated by a selective amplifier to yield the auxiliary signal. The main signal may comprise a broadcast programme, and the auxiliary signal used to identify the various items thereof. As shown, a microphone M originates a main signal, covering the frequency range between 50 and 7000 cycles per second, a filter F removes the narrow band 55-65 cycles, and the remaining signal passes to an amplifier A, where it is mixed with a low-amplitude 60 cycle tone from an oscillator O broken up by a Morse key K. The combined signal passes via line L to a broadcast transmitter, speaker or recorder BT. The line is also connected to a selective amplifier SA tuned to accept 55-65 cycles, and yielding the auxiliary signal in the form of a Morse-interrupted 60 cycle tone. The auxiliary signal may be conveyed as a high-frequency tone of say, 4500 cycles, or a combination of tones may be used. Instead of interrupting the tone, the Morse signal may give a slight frequency shift. The amplitude of the tone signal may be automatically regulated according to the frequency gamut of the main signal, or according to distortion conditions.

Title: Hydraulic valve assemblies
IPC: F16K11/22
Filed: 1973-03-02
Abstract: 1427042 Valves GRESEN MFG CO 2 March 1973 [2 March 1972] 10313/73 Heading F2V In a valve assembly for controlling two independent loads by means of spool valves 70, 130, additional spool valves 51, 111 are provided to control the distribution of the available operating fluid between the two loads in accordance with the demands of the loads and the pressures developed thereby and to bypass surplus fluid. The overall assembly comprises an inlet unit 11, two valve units 12, 13 and an outlet or exhaust unit 14. Included in each valve unit 12, 13 are relief and anti-cavitation valves 43, 44 and 103, 104. In Fig. 2, both spools 70, 130 are in the neutral position. On operating either of these spools an appropriate land on the operated spool blocks an open-centre pilot passageway 28 to close it from exhaust. This causes valve 25 to close, cutting off the inlet port 20 from an exhaust passageway 21. Valve 22 then opens to supply fluid to the valve units 12, 13. Fig. 7 shows spool 130 in a position to supply fluid to a load port 102, spool 70 being still in the neutral position shown in Fig. 3. With fluid now flowing into valve unit 12, pressure is fed via passageway 56 in spool 51 to the top of the spool which is forced fully downwards against the action of spring 52, a dump passage 54 being open to exhaust via the spool valve 70. All the fluid now flows into the valve unit 13 and via duct 150 to load port 102 to operate the load. If the fluid supply to the load exceeds the demand, pressure at the outlet and thus at passageway 107 will build up until a situation is reached where this pressure, fed via passageway 116 in spool 111, will move the spool downwards against the force of spring 112 and the pressure fed, via the axial and radial passageways 137 and 139 in the spool 130, to the bottom of the spool. Under these conditions some or all of the fluid is fed direct to exhaust, the control land of spool 111 being provided with metering grooves 117 to control this flow. Should pressure at the load rise to that at which a relief valve 160 is set to operate, the pressure fed to the bottom of the spool 111 is released and the spool moves even further downwards by-passing more or all of the fluid to exhaust. If spool 70 is positioned to supply fluid also to a load connected to load port 41 or 42, spool 51 will take up a position determined by the relative demands of the two loads which determine the pressures operating on the upper and lower ends of the spool.

Title: Power tool
IPC: B25F3/00
Filed: 1971-04-21
Abstract: 1357007 Power tools GKN SCREWS & FASTENERS Ltd 26 April 1972 [21 April 1971] 10374/71 Headings B3N and B3C [Also in Division F2]  A power tool comprises a body, two holders for mounting work implements in axially opposed directions, power means in or on the body, guard means on the body for guarding the implement not in use when the other implement is in use and means for moving the guard means relatively to the holders to bring one of the holders into its operating position while the other holder is in a position where its implement is within the region of protection of the guard means. In the embodiment shown in Fig. 1 the body comprises an outer sleeve 10 axially slidable on an inner sleeve 11. The body is rotatable upon a handle 14 in which an air motor 16 is mounted. Sleeve 10 has a plate 35 fixed thereto which plate has an aperture with a toothed rack 21 formed on one side which engages a gearwheel 20 fixed to an outer housing 15 of the handle. Thus rotation of the body about the handle causes the outer sleeve to move axially of the holders 22, 23 to expose one implement and provide a guard for the other. Plate 35 has a slot at each end, one side of the slot being longer than the other side. A trigger in the form of a bar 29 has a projection 37 adapted to engage the slots. As shown the projection abuts the long side of the slot and thus acts as an indexing stop during rotation of the body. Operation of the trigger causes the projection to fully enter the slot and thus lock the body to the handle. A U-shaped yoke 31 is attached to bar 29 and acts to operate a plunger which activates an air inlet valve when the trigger is operated. Fig. 5 shows a second embodiment with a single guard member 46. An intermediate body portion can swivel on a bearing pedestal 45. Location of the body and locking of the body to the handle is achieved by a nose 50 on the trigger mechanism engaging in slots 51. Fig. 7 shows a third embodiment in which a housing 60 is mounted on a swivel tube 70. The tube contains an air valve mechanism 72 that is rotatable therewith about the axis of handle 71. At each end of the body there are guards that comprise inner and outer sleeves. The inner sleeve has to be manually moved to expose an implement and is held in an inner position by a metal strip 83. When the body is rotated the inner sleeve is automatically released and spring biased to its outer position. In the reverse position the inner sleeve is held against movement by a lug 95.
