Filed: 1973-09-21
Abstract: 1494193 Rotary tubular heat exchangers R E DUPONT RESEARCH & INVESTMENT SERVICES Ltd 27 Nov 1974 [21 Sept 1973] 44423/73 Heading F4S [Also in Division F1] The invention relates to a fluid energy conversion machine for imparting energy to a fluid which comprises a rotor having means for the passage of a fluid channelled with a radial component of velocity between a smaller and a greater radius of the rotor. In accordance with the invention the rotor has, at the greater radius, channels which are directed with a substantial tangential component in the direction opposite to that of the rotation of the rotor, the channels together being of smaller crosssectional area normal to the flow through them than upstream of the channels. Thus fluid discharging from the rotor through the channels is accelerated and is discharged with a tangential component of velocity relative to the rotor in the opposite sense of direction to that of the rotation of the rotor. The invention is shown applied to a rotary heat exchanger which comprises a series of discs 4 and a series of axially extending tubes 5 through which fluid is caused to flow being cooled by fluid flowing radially outwardly between the discs 4. Between each pair of discs at the outer periphery is disposed a series of curved vanes 20 between each adjacent pair of which is defined a convergent flow passage 21, the fluid discharging through the outlets 22 in the direction of arrow 23, the tangential component of the vector 23 being ideally equal to but opposite in direction to the tangential velocity vector 24 of the impeller at that radius.

Title: Improvements relating to Apparatus for Displaying Information Corresponding to Electrical Signals
Inventor: BULL ERIC WILIAM
IPC: H04N7/01
Filed: 1965-10-28
Abstract: 1,165,342. Changing television standard. ELECTRIC & MUSICAL INDUSTRIES Ltd. 21 Sept., 1966 [28 Oct., 1965], No. 45630/65À Heading H4F. The Specification describes apparatus for converting a television display occuring at a low repetition (frame) frequency e.g. 5 c/s, to one having a high repetition frequency e.g. 25 c/s. The incoming low frequency pictures are fed to a two way switch 2 such that alternate frames are displayed on C.R.T's 3 and 4, the frame sync. pulses being separated from the incoming signal at 5 to produce the frame scan waveform which is applied simultaneously to the scan coils 8 and 9 of the C.R.T's. Each C.R.T has a long persistence display screen such that after one frame scan period of e.g. 1/5 sec. the intensity of a displayed line has decayed to 22% of its initial value-see Fig. 2 for decay of first (L1a), middle (Ln/2a) and last (Lna) line of C.R.T.3 display. Each C.R.T is viewed by a respective T.V. camera 10 and 11 having a high frame scan frequency-e.g. 25 c/s on scan coils 12 and 13 derived by frequency multiplying, e.g. by 5, the output of frame sync. separator 5. At for example time 3/2tf, (X-X in Fig. 2) only the upper half of the screen of C.R.T.4 has been covered, whilst the whole picture on C.R.T.3 is decaying, see Fig. 3. Thus if a complete up-to-date picture is to be obtained from the outputs of cameras 10 and 11 at said time, then the first upper frame half of the output of camera 11 should first be passed to the final display C.R.T.17, followed by the second, i.e. the brighter lower half of the output of camera 10. At the time of the next complete picture, the display on C.R.T. 4 has moved <SP>1</SP>/ 5 th scan further down, as has the 22% intensity line on C.R.T.3. Thus the output of camera 11 must be switched through to C.R.T.17 for the first <SP>7</SP>/ 10  of its scan, followed by the last <SP>3</SP>/ 10  of the scan of camera 10. A switching waveform applied to switch 15 must therefore have the form shown in Fig. 6, the positions of the advancing leading or trailing edge being controlled by a pulse train obtained by multiplying the frequency of the output of multiplier 7 (e.g. 25 c/s) by <SP>5</SP>/ 6 . Since the various parts of the gated camera outputs are at various intensities, an exponential multiplier 16 must operate on the outputs under the control of said switching waveform.

Title: Improvements in or relating to air conditioning of supersonic aircraft
Inventor: QUICK DESMOND FREDERICK JOHN
IPC: B64D13/06
Filed: 1962-11-23
Abstract: 976,564. Refrigerating; air conditioning aircraft. NORMALAIR Ltd. Nov. 22, 1963 [Dec... 4, 1962], No. 45734/62. Headings F4H and F4V A supersonic aircraft is air conditioned by passing pressurized air from the engines, of the aircraft through cooling means and an expansion turbine to the enclosure to be conditioned, and recirculating air from the enclosure through a compressor driven by the turbine and through cooling means back to the enclosure. As illustrated, air from two of the engines 1 and 2 of a four-engined aircraft is passed through pressurereducing and shut-off valves 3 and 52 and non- return valves 4 and 53 and led by a conduit 39 through a ram air heat exchanger 5 and a fuel cooled heat exchanger 6 to an expansion turbine 7. A conduit 42 leads air from the turbine through a water extractor 8 to a conduit 43 which discharges into the aircraft cabin 48 at 10. The turbine 7 drives a compressor 13 which draws air from the cabin through a conduit 44 including a non-return valve 12 and passes it through a fuel-cooled heat exchanger 14 to a second compressor 15. The air passes thence through a cooler 17 and an expansion turbine 16 driving the compressor 15, to the distribution conduit 43. A conduit 36 controlled by a butterfly valve 26 allows air from the primary conduit 39 to pass to the compressor, 13 if the primary air supply pressure is low. The valve 26 is electrically or pneumatically operated by a flow controller 27. A conduit 41 controlled by a valve 24 by-passes the expansion turbine 7 and a conduit 40 controlled by a valve 25 bypasses the heat exchangers 5 and 6. Valves 24 and 25 may be controlled manually or automatically by a cabin temperature controller 20 in response to cabin and duct temperature sensors 19 and 21 a high limit thermostat 22 and a low limit thermostat 23. A manual override selector 18 is provided. At the end of a flight when the heat sink value of the fuel is low, the cooling effect of the ram air is high and the primary air pressure low, a valve 29 in a conduit 50 operates to by-pass the heat exchanger 6 and the turbine 7. Valve 29 may be controlled manually or by a temperature controller 28 in response to temperature sensors 30 and 35. A system similar to that described above, Fig. 2 (not shown), is fed with air from the other two engines of the aircraft and conditions air for the flight deck 49. The two systems are joined by a duct 37 to allow either or both to be operated by an auxiliary power unit 31 normally disconnected by a shut-off valve 32. The systems are further connected by a duct 34 so that if one system fails, its distribution ducts may be fed from the other system. In modifications (not shown) a ram air heat exchanger is substituted for one of the fuelcooled heat exchangers, and during the higher altitude stages of aircraft descent a controlled discharge to the atmosphere of bleed air from the turbine 7 may be allowed.

Title: Fastener driving apparatus
IPC: B25C1/04
Filed: 1963-11-25
Abstract: 1,060,659. Stapling machines. FASTENER CORPORATION. Nov. 25, 1963 [Dec. 21, 1962], No. 46434/63. Heading B4C. A stapling machine comprises a piston 20 for actuating a driver 22 and slidable in a cylinder 18 having an open top which is selectively placed in communication with a reservoir 16 of pressure fluid by a main control valve 54, fluid-means 88 for returning the piston from an operated position to a normal position, and control means 96 responsive to the pressure within the cylinder above the piston for selectively operating the fluid means. The cylinder 18 is slidable within a chamber 14a, 14b, the upper open end of the cylinder normally being in sealing contact with a resilient disc 54. The lower end of the cylinder is of reduced diameter and is adapted, upon downward movement, to abut a valve member 40 loaded by a spring 41 to a normally closed position shown. The control means 96 has a piston (96b, Fig. 2) communicating with the cylinder via a port 110 and with the reservoir 16 via a port 94, the piston being connected to a valve (96a) controlling the flow of compressed air from the reservoir to the underside of the piston 20 via a passage 88. A vent valve 68 is maintained in the normally open position shown, by means of compressed air fed from the reservoir via a port 86 and passages 76, 78, so as to act on a piston 60 connected to the vent valve. In operation, upon actuating a valve 28, the flow of compressed air which has been acting on the lower end of the cylinder so as to maintain its upper end in contact with the valve disc 54, is cut off thereby allowing the cylinder end to move away from the disc and thus permit the air to act on the piston 20; the downward movement of the cylinder immediately causes the valve 40 to open, thus permitting the air below the piston to escape to atmosphere. The operation of the valve 80 also causes the supply of air to the vent piston 60 to be cut-off so that the air pressure acting on top of the piston 20 also acts on the lower side of the piston 60 to close the vent valve, the piston 20 then being driven downwardly. The piston 20 remains in the lower position until the valve 80 is released, thereby causing the cylinder to rise and again abut the disc 54. Compressed air which has been acting on the piston (96b) via the port 110 is then cutoff and the latter piston is raised by pressure acting on the underside via the port 94. Air then passes through the passage 80 to raise the piston 20. A rubber buffer 50 is provided for the piston 20.

Title: Electrochemical machining of metals
Inventor: BASS LUDVIK
IPC: B23H3/02
Filed: 1961-12-29
Abstract: In a process for the electro-chemical machining of metals (workpiece 2) by passing a direct current across a gap filled with electrolyte by a feedpipe 3, is varied to a known extent by oscillating the operative surface of the tool 1 or the workpiece, the amplitude in the feed direction being known and small in comparison with the gap, and the resultant ripple produced on the direct electrical current flowing across the gap is compared with the value of the direct current to give an indication of the mean size of the gap.  In a servo arrangement in which the feed of the tool 1 by a servo-motor 13 is such as to maintain a pre-determined gap size the ripple due to oscillation is compared with the three phase rectification ripple in the split field windings 12 to which they are respectively supplied by air cored current transformer 6, 7, filters 8, amplifiers 9, rectifiers 10 and power amplifier 11. The gap size is given by the ratio of the indicators 9, and a stabilizing voltage from a tachometer is fed back to the power amplifier. The tool is vibrated by an ultrasonic transducer 4 and typical frequencies are given. Alternatively, in a machine for cutting or slitting, the electrode could be a rotating disc having a toothed or wavy periphery. <PICT:1037661/C6-C7/1>
