Title: Method of burning unpurified shaft furnace top gas in slag tap furnaces
Inventor: WOLF OTTO
IPC: F27D17/00
Filed: 1963-05-06
Abstract: A method of using unpurified shaft furnace top gas as a fuel for combustion in a slag tap furnace is characterized in that prior to its admission into the furnace the top gas is heated to raise its temperature to at least such a height that on combustion of the top gas, dust particles in the top are melted; e.g. both top gas and combustion air or gas may be heated to temperatures exceeding 700 DEG C.  The top gas or the top gas and combustion air, prior to entering the slag tap furnace, may be conducted over the liquid slag leaving the furnace or rotary drum if one is provided to receive the slag from the furnace, or may be passed through the slag if this is arranged to flow over a weir.  Alternatively the top gas and combustion gas may be introduced tangentially into a slag vessel, e.g. from opposite sides thereof so that the slag rotates within the vessel and is heated by the partial combustion of the top gas, during which process some of the dust contained therein is melted and simultaneously the top gas and combustion gas become heated; or the gases may be forced under pressure into the liquid slag bath.

Title: Improvements in machines and methods for manufacturing tubes and other hollow bodies from pulp
IPC: D21J3/00
Filed: 1922-06-29
Abstract: 209,115. Marks, E. C. R., (Brown Co.). June 29, 1922. Moulding pulp tubes. -The wet web of pulp from which, by winding on a mandrel, tubes and other hollow articles are formed, is broken at a point distant from the mandrel when the material wound reaches approximately the finished thickness, the winding being continued and the end wound up and finished off, before the mandrel is removed. The pulp is contained in a vat V and is picked up by and carried to a winding mandrel M on the surface of a continuously driven wire apron d passing around a cylinder e in the vat. Lower press-rolls a, a<1>, mounted in bearings in the pedestals A of the machine, and an upper-roller b, mounted in bearings in carriages 50 vertically slidable relatively to the. frame of the machine, co-operate in winding the material on the mandrel. The upper press-roll b as it rises with the thickness of material wound, operates a trip mechanism to set a cam in motion to lower a roll 136 on the web and sever it. This roll is kept lowered and the pulp web is prevented from advancing and is returned to the vat until the winding is finished, when the press roll b is automatically raised to allow an intermittently driven conveyer 3 carrying a number of mandrels M to move a step forward to remove the wound mandrel and replace it by a new one. The wound mandrels are automatically discharged from the conveyer to a platform G fresh mandrels being picked up from a platform H. The upper press roll b is lowered gradually by a dash-pot device to exert pressure just as the new mandrel is positioned, when winding is resumed and the sequence of operations repeated. Specifications 210,715 and 210,716 are referred to.

Title: A device for the sequential operation of flow control valves
Inventor: QUIRK MARTIN RICHARD
IPC: G05D11/03
Filed: 1965-04-30
Abstract: 1,137,262. Valves. JOHN I. THORNYCROFT & CO. Ltd. 9 May, 1966 [30 April, 1965], No. 18238/65. Heading F2V. [Also in Divisions F4 and G3] Oil is supplied to the four burners of a furnace or boiler via a main control valve 20 and individual burner valves, the latter having control stems 11-14 urged to a valve-closed position by springs 15-18. When valve 20 is closed, upstream pressure acts via line 27, an annular space 28 between a fixed cylinder 29 and its fixed support 47, and ports 30 on a piston 24 to move the latter to the right. A carriage 44 mounted via rollers on support 47 has a lostmotion connection at 63, 64, 66 with piston-rod 26 and a lost-motion connection at 60, 61 with a cam 32. Thus, when the piston is moved to the right, the carriage 44 and cam 32 are similarly moved until they abut a stop 53. In this position all the burner valves are closed by their springs. When valve 20 is progressively opened, the downstream pressure rises until it reaches a value at which it causes leftward movement of the piston 24 by acting on the latter via line 31 and restriction 62. The magnitude of the downstream pressure required to move the piston is determined by a roller 55 carried by a lever 56 and urged into contact by spring 59 with an undulating track 54 adjustably mounted on carriage 44. The arrangement is such that initial movement of the piston causes the carriage to move relative to the cam, and the roller 55 ascends an incline on track 54. When the roller reaches a peak on the track, pin 60 is at the end of slot 61 and as the roller passes the peak the energy stored in spring 59 drives the roller downwardly and thereby imparts a rapid movement to carriage 44 and cam 32, the latter engaging a lever 39 to open the burner valve to which stem 14 is attached and thereby reducing the downstream pressure. Further opening of valve 20 causes sequential opening of the other burner valves. A similar sequence occurs in reverse when valve 20 is progressively closed. Over-riding manual controls may be provided on the burner valves.

Filed: 1946-06-19
Abstract: 632,078. Directive radio systems. PHILIPS LAMPS, Ltd. June 19, 1946, No. 18438. Convention date, March 20, 1942. [Class 40 (vii)] The directivity of an aerial array comprising a number of spaced radiators is varied cyclically by feeding the radiators from a frequencymodulated radio-frequency source through separate frequencydependent phase shifters. As shown in the Figure, the output from a Hartley oscillator 21 is frequency multiplied at 5 up to 600 mc/s., i.e. #= 50 c.m., and applied through transformer 6 and phase shifters 15-18 to the #/2 dipoles 1-4 which are spaced apart by #/4. The phase shifters comprise transmission lines of length 0, 10, 20 and 30 metres producing phase shifts of 0, 20, 40 and 60 wavelengths respectively so that a directive beam is produced normal to the line of the dipoles and the direction of the beam is varied periodically about this position by varying the frequency of the oscillator 21 by means of a reactance valve 22 controlled by a L.F. oscillator 25. In order to produce a linear scan with a rapid flyback the oscillator 25 should generate a saw-tooth waveform ; alternatively the frequency of oscillator 21 may be varied by a rotating condenser. When the aerial spacing does not exceed #/2, side lobes may be reduced by adjusting the currents in the radiators to be proportional to the coefficients of a binomial series. The transmission line phase shifters may be replaced by networks with lumped characteristics. The invention is stated to be applicable to scanning radar systems. Specification 577,672 is referred to.
