Title: Improvements in or relating to the treatment of coal and other carbonaceous material
IPC: C10B49/04
Filed: 1929-12-07
Abstract: 346,383. Fuel. WHITE, A. E., 5, Quality Court, Chancery Lane, London.- (Thermolized Coal Corporation; 17, East 42nd Street, New York, U.S.A.) Dec. 7, 1929, No. 37579. Drawings to Specification. [Class 50.] A method of heat-treating coal or other carbonaceous material comprises crushing the coal and heating the pieces in an inert atmosphere at a temperature of from about 250‹ F. to about 450‹ F. for a period sufficient to effect the heating of the pieces throughout their mass. A plant for carrying out the process is described comprising a column in which the pieces of coal are washed by furnace gases, a crusher, a rotating heating and expanding chamber, a cooling hopper, and a ball-mill or like comminuter, through which the fuel passes in succession, furnace gases from the heater being circulated through the series. The process causes the release of water vapour and imprisoned gases while stopping at the temperature at which the decomposition and gasification of the fuel begins. Reference has been directed by the Comptroller to Specification 24299/14, [Class 50, Fuel, Manufacture of].

Title: Improvements in or relating to phase difference measuring apparatus
Inventor: ELLIS ALFRED BRIAN EDWIN
IPC: G01R25/00
Filed: 1965-09-03
Abstract: 1,145,844. Phase difference measurement. MARCONI CO. Ltd. March 28, 1966 [Sept. 3, 1965], No.37834/65. Heading GlU. In a method of measuring the phase difference between two continuous alternating electric signals, the first is applied to the Y plates of a cathode ray oscilloscope, while the second is squared and differentiated and then applied to the brightness control of the oscilloscope. If the oscilloscope has a conventional time base, the position of a bright dot on the waveform display indicates the phase relation between the two signals. The first signal may be half-wave rectified or converted to a triangular waveform before being applied to the Y plates. A permanent record may be obtained by passing photographic film across the screen of the oscilloscope, and not applying a time base.

Title: A spindle for lace and braid making machines
IPC: D04C3/14
Filed: 1938-12-30
Abstract: 523,319. Braiding-machines. CASPERS. P. Dec. 30, 1938, No. 37898. Convention date, Dec. 31, 1937. [Class 74 (i)] Relates to tension and let-off arrangements for bobbin-carriers. The thread from the bobbin 4 is passed through eyes 15, 10, 18 and 16. Eyes 15, 16 are fixed to a slotted tube 6 mounted in the bobbin carrier 1. Eye 10 is fixed to a tube 7 suspended from a tension spring mounted within the tube 6. Eye 18 is part of a pivoted yoke 17 encircling and normally held against the tube 6. If the thread breaks, the yoke 17 drops and actuates a stop-motion. The lower part of the bobbin carries a ratchet 5, which normally is checked by a detent 12 forming part of a block. 11 mounted loosely in the tube 6 and resting on a spring 13. As the thread is used up and tension increases, the tube 7 descends until the lower end abuts on a stay 14 and depresses the block 11 against the pressure of spring 13 until the ratchet 5 is released and the bobbin is temporarily free to unwind. Fig. 6 shows a modification in which a block 7, supported by the thread, is drawn up in the tube against the adjustable tension of a spring 8 until it engages an extension 24 of the block 11 and so releases the bobbin. If the thread breaks the block 7 descends and presses the release member 17 against a spring 26 into stopmotion actuating position. In another modification, the block 11 itself engages the ratchet 5, the locking lug being dispensed with. In another modification the ratchet 5 is rotatable m the support 3 and is coupled to a metallic flange of the bobbin by a pin.

Title: Improvements in and relating to the manufacture of propellers
IPC: B23Q35/10
Filed: 1930-12-16
Abstract: 369,226. Milling screw propellers. G E B E R S, F., 256, Brigittenauerlõnde, Vienna. Dec. 16, 1930, No. 37910. Convention date, Jan. 21. [Class 83 (iii).] In a method of milling the surfaces of screw propellers, a milling cutter 1, Figs. 7 and 4, rotating in a plane containing a generator 2 of the propeller surface is fed in a direction parallel to the -propeller axis while the propeller is simultaneously rotated to produce a cut 6 on the work. The cutter is fed radially along the propeller blade between successive cuts, the ridges 7 left on the work being subsequently removed by hand. The cutter is driven by gearing from a motor 14 and is mounted on a slide 15 which may be operated to feed the cutter radially of the work. The slide is carried by a turntable 16 which may be angularly adjusted for cutting propellers having inclined blades. The carriage 9 supporting the cutter slide carries a roller 9a and is urged by a weight 17 against a pitch ruler 11 carried by a table 10 which may be traversed along guide-rails by means of a screw 18. The table 10 carries a rack 20 engaging a toothed segment on an arm 21 secured through an angularly-adjustable coupling 22 to the propeller shaft 13. Thus in operation, as the table 10 is moved forward, the pitch ruler causes the milling cutter to be fed forward in the direction of the propeller axis while at the same time the propeller is rotated at the rerequired speed by the sector 21. The apparatus can also be used for milling the back surface of the propeller, a curved guiding-ruler being employed and the milling-cutter being placed in the position shown at 1<1> in Fig. 7. Curved guiding-rulers, such as adjustable flexible steel members, may also be used for milling propeller surfaces of variable pitch.

Filed: 1962-10-08
Abstract: 943,769. Rectifying. LICENTIA PATENTVERWALTUNGS-G.m.b.H. Oct. 8, 1962 [Oct. 7, 1961], No. 37986/62. Heading H2F. Reverse parallel connected controlled rectifiers 1, 2 (semi-conductor or mercury arc rectifiers, or thyratrons) supplying a load 4 with direct current of one polarity or the other from an alternating source 3 are controlled through individual saturable transformers having bias windings 12, 22 series connected to a D.C. supply, and the senses of the biases and the primary signals, which are continuously applied to both transformers, are such that in one transformer the signals produce a magnetizing force in the sense in which the transformer is already saturated, and in the other the signals reverse the flux, so producing a pulse in the secondary winding and firing the corresponding rectifier. Two or more transformers having cores with different coercivities and receiving phase-displaced primary signals may control each rectifier. As these will respond to different values of bias current, the load current may be varied in steps to follow the bias current in magnitude and sense (Figs. 5, 6, 7, not shown).

Abstract: 1,191,473. Utilizing waste heat. S.A. TIPPETTS, H.R.M. TIPPETTS and H. MILLENER. July 23, 1968 [Aug. 18, 1967], No. 38172/67. Heading F1B. [Also in Division F4] In a power unit comprising an internal combustion engine having a liquid coolant circuit, the circuit includes two parallel paths, an engine cooling jacket being in one path and an exhaust boiler in the other, and the coolant is used to heat a thermal load. As shown, the coolant circuit has two pumps 11 and 12 which respectively pass coolant through the jacket of engine 2 and through an air cooler 10, an exhaust boiler 8 and a cooler 9 for the exhaust manifold. The coolant streams recombine and pass through line 15 to a coil 6 located within a hot water tank 5 and the coolant then returns to the pumps via lines 18 and 20. If the temperature of the coolant leaving the engine is too low, a thermostatic valve 16 diverts the coolant directly to the pumps via by-pass line 26 and if the temperature air line 18 is too high a thermostatic valve 19 diverts the coolant through a heat exchanger cooled by a further coolant in coil 21. The engine drives air alternator 4 which supplies current to a thermostatically controlled immersion heater in tank 5. The power unit may be used to provide electrical lighting and electrical power for space heating, cooking, winches and other electrical motors as well as hot water and may be a shipboard installation. The engine is preferably a diesel engine employing glow plugs for starting and may also power a refrigerant compressor or a decompressor used in conjunction with evaporators for the production of fresh water. A secondary closed coolant circuit may be employed for transferring heat from the engine coolant circuit and the thermal load.

IPC: H02K3/34
Filed: 1961-10-26
Abstract: 940,050. Insulation for dynamo-electric machines. EPOXYLITE CORPORATION. Oct. 26, 1961 [April 17, 1961], No. 38322/61. Heading H2A. The winding slots of the magnetic core of a dynamo-electric machine have disposed in them two coaxial tubes surrounding the windings in the slots, the outer tube being of non- magnetic metallic foil and the inner tube of dielectric insulating material. As shown in Fig. 3, a sheet of metallic foil 20 such as aluminium or stainless steel is placed in a slot 11 of a laminated core so as to line the slot and a thin sheet of dielectric insulating material 30 such as paper, varnished fabric, glass, mica or polyester resin, is laid loosely within the metallic sheet. After inserting the conductive windings 40 in the slot, for which a central stick 50 may be provided, the edges 31, 32 of the dielectric material are folded over to form an overlapping seam. The edges 21, 22 of the metal foil are then folded over and bonded to each other by an epoxy resin and the tubes are kept in position by wedges 60. The dielectric tube preferably extends beyond each axial end of the metallic tube, Fig. 5 (not shown) so as to prevent the windings shorting with the metallic foil. In an alternative embodiment, Fig. 6, sheets 20a, 30a, identical to sheets 20, 30 respectively except that they have a shorter circumference, are inserted in the slots and windings 40 emplaced therein. The insulating material 30a is first closed to form a complete tube by placing over the gap at its upper end a curved strip 61 of insulating material which overlaps the ends of the sheet and is bonded thereto by adhesive material. Similarly the gap at the top of the foil sheet 20a is closed by a strip of foil 62 bonded to the foil sheet by an epoxy resin. The winding may be encapsulated in the tubes in an insulating material and the axial ends of the tubes are secured and covered by an epoxy resin.

Abstract: 837,576. Fluid-pressure brakes. CLAYTON DEWANDRE CO. Ltd. Dec. 1, 1958 [Dec. 10, 1957; Jan. 14, 1958], Nos. 38374/57 and 1330/58. Class 103 (1).  A fluid pressure-operated servo-assisted braking apparatus of the type disclosed in Specification 550,540, comprises two independent hydraulic systems for operating separate brakes and each embodying an auxiliary cylinder 11, 12, combined into a unit or mounted for common actuation by servomotor 1, 2, and a pedal operated dual transmitter 25 incorporating two master cylinders connected, respectively, by lines 26, 27 to auxiliary cylinders 11, 12, the pressures in lines 26, 27 being each transmitted to the hydraulic motor 33, 34 for actuating the control valve 5, so that a degree of braking control is retained irrespective of failure in either system. Actuation of transmitter 25, comprising two parallel or in-line master cylinders, creates pressure in chambers 28, 29 to advance pistons 13, 19 to actuate both sets of brakes. The pressure also acts via passages 45, 44 and 46, in chambers 41, 36 of valve 5, the pressure on piston 33 being balanced to maintain the piston in the shown position whilst piston 34 is moved to operate valve 5 to admit air through pipe 4 to the rear of the vacuum suspended piston 2 which moves piston 13 through rod 14 to boost pressure in cylinder 11, which pressure is transmitted to cylinder 12 by floating piston 15, rod 20 and piston 19. Should a leak occur on the output side of cylinder 11, then pressure in line 26 passes through piston 13 via ball valve 13a, the piston remaining stationary; pressure in lines 27, 45 operates cylinder 12 and valve 5 to actuate motor 1, 2 which displaces piston 13 until it abuts piston 15 to transmit the output of motor 1, 2 mechanically to cylinder 12. Should a leak occur on the output side of cylinder 10, then piston 13 will be operated but no pressure created in cylinder 11 due to yielding of piston 15 because of absence of pressure in cylinder 12, fluid in front of piston 15 escaping through passage 47 and lines 48 and 26; when piston 15 abuts the end of cylinder 11 the piston 13 operates normally. The pressure in chamber 36 actuates piston 34 through piston 33 and spacer 40 to actuate valve 5. Should a leak occur on the input side of either cylinder 11 or 12 then the other cylinder and system is operated as above. Movement of piston 13 is transmitted to piston 15 by liquid pressure in cylinder 11 but in the first Provisional Specification this movement is transmitted by a rod and lostmotion connection between the pistons 13, 15.
