IPC: G11B5/86
Filed: 1925-01-30
Abstract: 256,558. Sykes, A. F. Jan. 30, 1925. Records, duplicating. - Relates to the production and duplication of sound records by electromagnetic means, and consists mainly in a method of producing a record and also one or more modified duplicates thereof, differing, for example, in amplitude and wave form, by using electrical recording apparatus controlled from the same source of potential. The Figure shows diagrammatically a system for carrying out the invention. A recording instrument, comprising an armature 291 vibrating between magnetic poles and carrying a winding to which acoustically controlled currents are supplied by means of a microphone and amplifier, is caused to engrave upon a blank sound record which in turn vibrates the needle 3 of an electromagnetic generator. This is coupled through a transformer 157, valves 44, 46, and an output transformer 59 to one or more electromagnetic recorders 3<11>. In shunt with the intervalve resistance 193 is a tone-control circuit comprising a resistance 55, condenser 56, and an inductance 45, all these being variable over a wide range. By this means, anv desired modification of the original record may be produced by the secondary recorders 3<11>.

Title: Process for recovery of oxides of sulphur from waste combustion gases
IPC: B01D53/81
Filed: 1973-04-18
Abstract: 1380869 Removing sulphur oxides ASAHI GLASS CO Ltd 18 April 1973 [1 Aug 1972] 18826/73 Heading C1A Sulphur oxides are removed from hot waste gases by introducing a solution of sodium hydroxide and/or sodium carbonate into a stream of the gas as a finely divided spray so that solid particles are formed from the spray and are carried by the gas through a zone in which they absorb the oxides of sulphur from the gas stream, and during such absorption, conditions are provided such that the particles are abraded or fractured so that fresh absorption surfaces are exposed to the gas stream; the resulting particles and dust being separated from the cleansed gas stream. A suitable apparatus is shown in Fig. 1 where waste gas from a glass furnace 1 is discharged via 2 into a cooling tower 3 where it meets a spray of aqueous solution containing NaOH and/or Na 2 CO 3  from an array of nozzles. Solid particles form, and those which adhere to the vessel walls are washed down with water supplied via 10. These particles ultimately dissolve in the water and are recycled to supply tank 8. The gas cooled by the spray to 200 C. to 350 C. carries forward some of the particles formed from the spray into a reaction chamber 12 where the particles react with the sulphur oxide content of the gas, and are simultaneously abraded or fractured to produce fresh absorption surface by impinging against plate like members positioned in chamber 12. These members may be V-shaped and overlap each other across the section of the chamber so that any particles present in the gas necessarily impinge against them. The members may be attached to a vibrating mechanism (Fig. 2, not shown) so that only a small amount of particulate material adheres to the plates. The waste gas then passes on and any residual dust is removed in a subsequent separation step, e.g. electrostatic precipitator 13. The cleansed gas passes on to atmosphere via stack 15. The total amount of sodium hydroxide and/or sodium carbonate introduced into the gas is preferably 0À9-1À5 equivalents of the sulphur oxide content. The solid particles may be 30-50 microns on formation and may be reduced to a size of 0À5 to 1 micron after fraction and/or abrasion. The spray nozzles may include cooling means to keep them below the dew point of the surrounding gaseous atmosphere.

Title: Improvements in electric switches
Inventor: FLETCHER JOHN
IPC: H01H13/14
Filed: 1958-06-14
Abstract: 932,804. Retractive switches; switch cases. DOWTY ELECTRICS Ltd. Aug. 19, 1959 [June 14, 1958], No. 19102/58. Class 38 (5). A switch mechanism substantially as in Specification 685,332, is hermetically sealed and has its actuating member arranged to avoid excessive movement upon overtravel of the operating member. An actuating plunger 12 is slidable in a cylindrical extension 20 of the casing 1 and has a shoulder 19 and washer 21 to limit its movement to little more than that necessary to operate the switch contacts. A metal bellows 26 is brazed at its lower end to the plunger 12 and is soldered at its upper end to cylinder 20. A hat-like member 32 is screwed to the top of plunger 12 to slidingly fit over the cylinder 20 and is enclosed in a cage formed by member 34 (also sliding on cylinder 20) and a cap member 35 to which the operating force is applied. A spring 33 is pre-loaded between cap 35 and a flange on member 32 such that initial movement of cap 35 moves plunger 12 to operate the switch but any overtravel is absorbed by the spring 33. Springs 22 and 42 ensure retraction of the plunger 12 when the operating force is removed. A rubber cover 43 is sealingly secured to cage member 34 and cylinder 20 by metal clips 45 and 46. Preset adjustment of the switch operation is made by a bolt 24 and locknut 25. Magnets 7 and 8 reinforce contact pressure. Connecting wires 54 extend from the switch contacts to terminals 57 through glass seals 52 in a soldered end-plate 51. The space between the plate 51 and terminal block 55 is filled with a cold setting resin, and a rubber boot 61 having sleeves 62 for the connecting cables is clamped over the terminal block by a metal ring 63. The casing is filled with dry air through a hole 67 which is then closed by solder. Tubes 64 are brazed to the casing 1 to accommodate mounting bolts. The Provisional Specification refers to use on aircraft in exposed positions, for example, to indicate undercarriage operation, and also states that a small window is provided in the casing with a capsule of cobalt chloride therein to indicate sealing failure by changing its colour upon entry of dampness.

Title: Phase and frequency comparator
IPC: H03K5/26
Filed: 1974-05-01
Abstract: 1461459 Phase detection in afc systems THOMSON CSF 1 May 1974 [14 May 1973 16 May 1973] 19192/74 Heading H3A A phase and frequency comparator for two input signals in which, when the amplitude of one input is zero the sign of the phase of the other relative to the first is determined as a two valued signal and in which means are provided for detecting if this signal (a) differs from that resulting from a previous comparison and (b) occurs when the phase of the other signal falls within a predetermined range including only a single zero value. The two signals to be compared are applied at inputs 1, 2 to respective limiters 10, 11 which produce square wave output signals. The output of limiter 10 is fed to the input of a shift register 13 and that of limiter 11 is fed to a differentiator and monostable 12 which provides clock signals for register 13. When the two signals are at the same frequency, the clock signal will always sample the other signal at its high level or its low level depending on whether the signal 1 leads or lags signal 2, so that the output 4 from the register 13 will either be at a logical "0" or "1". The output from register 13 is also fed to a second register 14 which is clocked by the same signal and which delays the output from register 13 by one clock period. The outputs from the two registers are applied to an exclusive-or circuit 15. If the two input signals are at different frequencies, the circuit 15 will periodically produce output pulses which are used to trigger a further monostable 16. The square wave signal from limiter 10 is delayed by #/2 in a delay 17 and the delayed signal and that from the monostable 16 are fed to AND gate 18 to produce clock pulses for a shift register 19, which receives at its input the output 3. The output of register 19 is either at a "0" or "1" state depending on which of the two input frequencies is the higher. The arrangment may be used in an AFC system, Fig. 2 (not shown).

Abstract: 359,516. Lathes. NOBLE & LUND, Ltd. and NOBLE, P., Northern Machine Tool Works, Brewery Lane, Felling-on-Tyne. June 24, 1930, No. 19239. [Class 83 (iii).] Drivers and carriers.-A lathe for turning up railway wheels and the like is provided with driving means wherein each driver is provided with a pivoted cam-shaped gripper which is normally locked in an inoperative position but which is unlatched after a predetermined axial movement to allow a spring device to move the gripper into engagement with the work. The lathe comprises a stationary stock 1 and a movable stock 2, the work being carried on a lift 3 which raises it to the required position and is also movable longitudinally. The axle ends are fitted with conical adaptors 24 engageable with the spindles. Each face-plate 4, 5 has two diametral plates 6, 7 which interengage so that their outer ends are in the same plane while central oval holes are formed at 10, 11. Springs 12 arranged as shown in Fig. 4 permit a floating movement of the plates to equalize the pressures of opposite drivers. Mounted at opposite ends of each plate are gripper-holding members 15, adjustment for different sizes of wheels being obtained by means of serrations 26, 27 in the plates and corresponding serrations 15a in the gripper holders. The latter are bored to receive the spindles 16 of the eccentric serrated drivers 17 which are urged into engaging position by a spiral spring 18. Normally the driver is urged outwardly by a spring 23 into such position that a pin 22 engages a notch 20 in a reduced portion of the spindle 16. When the stock 2 is moved up to the work, each driver engages the wheel and is moved axially thus disengaging the pin 22 from its notch and allowing the spring 18 to rotate the driver into engagement with the work. The stock 2 and lift 3 are then moved longitudinally until the drivers on the stock 1 are similarly brought into engagement. In the case of disc wheels the driver spindle may be fitted with an extension 25, Fig. 10, which engages the disc to effect the unlatching of the driver.

Title: Improvements in and relating to steam power plants
IPC: F01K7/22
Filed: 1943-11-19
Abstract: 571,451. Steam turbines. FIELD, J. F. Nov. 19, 1943, No. 19411. [Classes 110 (i) and 110 (iii)] Steam is supplied at high temperature from a pipe 10 to a superheater 2 where the temperature is raised as high as the materials of construction of superheater and turbine or engine will permit. In the initial stages, steam passes through a turbine wheel, back to the superheater, through the second turbine wheel and so on to the stage A, where the steam flows through 'the remaining turbine stages to 'a condenser- 9. The condensed steam is pumped by a pump 12 through a feedheating system 11, which is heated by steam bled from-the turbine through pipes B, compressed adiabatically and cooled step by step before being added to the main returning flow of feed water or steam in such a way that the temperature difference between the compressed steam and the returning feed water or feed steam, is of small order. Air for combustion in a furnace 1 enters through an inlet 6 and is heated in pipes 4 before passing to the furnace through a duct5. The fuel supply is controlled by a valve 3 coupled to a speed governor 15, and may also be coupled to the inlet steam nozzles to the turbine, from the superheater 2. The shating for the pump 12, and feed-water compressor, may be driven by a mechanical or electrical coupling 13. The turbine drives a generator 14. The plant may be started up by generating steam in an auxiliary boiler (not shown). In a modification bleeding of steam from the turbine or engine may commence at a temperature considerably below the maximum operating temperature of the turbine or engine. Temperatures and pressures of the working fluid are referred to in the Provisional Specification.
