Title: Sludge drying furnace with gas deodorizing chamber
IPC: F23G5/28
Filed: 1956-08-17
Abstract: 789,793. Consuming smoke. NICHOLS ENGINEERING & RESEARCH CORPORATION. Aug. 17, 1956 [Nov. 30, 1955], No. 25258/56. Class 51 (1). [Also in Group XIII] In a sludge-drying furnace, hot gases from burners projecting into the first of two compartments formed at the top of the furnace pass through a drop-hole to the furnace below, and gases from the lower part of the furnace are conducted to the second compartment at the top of the furnace where they are subjected to high temperature flames. Sludge fed through inlet 22 passes down a series of hearths 11 with rotary rabble arms 14 and peripheral or central drop holes 16, 15 to the outlet 23. Above the top hearth 11 two compartments are formed, divided by a diametral wall 20 with an arcuate middle portion 20a to allow for central drop hole 21. Burners 24 directed radially inwardly through the furnace wall produce hot gases which flow downwardly through the drop hole 21 over the hearths below. Dampered outlets from the lowest hearth and an intermediate hearth lead up to inlet 27 to the second compartment, where burners 37 project high temperature flames into the tortuous path formed by baffles 33. A checker-work wall 38 increases the turbulence of the gases. Dampers 43 in the wall 20 allow gases to pass directly to the second compartment if the furnace becomes overheated. An auxiliary dampered connection to the intermediate hearth enables the lower part of the furnace to be operated separately.

Title: Improvements in and relating to the production and modulation of electrical oscillations by means of thermionic valves
IPC: H03C1/22
Filed: 1920-09-02
Abstract: 172,389. Taggart, J. Scott-, and Radio Communication Co., Ltd. Sept. 2, 1920. Thermionic modulating systems.-In a controlling or modulating system, high-frequency currents applied to the grid of an amplifying- valve are more or less neutralized by variable currents of the same frequency but 180‹ out of phase with the currents to be amplified. The opposing currents are derived inductively from the grid curcuit or in any manner from the anode circuit of the amplifying-valve. In an example, Fig 2, a high-frequency generator S supplies oscillations through a transformer L4, L1 to the grid end of an amplifier valve V,. An inductance L2 coupled to one of the inductances L1, L3, L4, and in series with a two or three electrode valve V2 whose resistance is varied by a microphone M supplies across the resistance R oscillating potentials of varying amplitude in opposition to those produced in the inductance L7. In another example the generator S is omitted and the valve V1 made self-oscillating by coupling the coil L1 to the coil L,. In a further example, Fig 3, the output of the self-oscillating or amplifying valve V1 is controlled in accordance with speech in the microphone M, which varies the amount of current through the valve V2 and consequently the potentials across the resistance R. Specification 169,250 is referred to. One Provisional Specification describes an arrangement in which oscillations produced in a grid or anode circuit of the generator valve are applied across the grid and filament of an amplifier valve in the anode circuit of which is an inductance coupled to the main grid coil so as to induce opposing electromotive forces. A microphone transformer is included in the grid or anode circuit of the second valve. In. an example described in another Provisional Specification the resistance R may be replaced by an inductance or impedance and the coil L2 is replaced by a connection across a part of the aerial coil. Also the resistance R, Fig 2, need not be included in the grid current of the valve V1 which is given a second grid to which are applied the varying potentials derived from the resistance R.

Abstract: 1,274,835. Optical filter apparatus. XEROX CORP. May 28, 1970 [June 4, 1969], No. 25644/70. Heading G2J. An optical filter apparatus 20 for selectively inserting an optical filter into a moving light beam of an optical system, for example a photo-copier, comprises a plurality of optical filters 26, means to insert a selected one of the filters into the light beam and means to move the apparatus so as to maintain the selected filter in the moving light beam. Each filter is mounted in a frame 27 slidable in tracks 24 and 25 in a housing 21, and each frame has an arm 50 protruding through a slot 49 in the housing. A pair of springs 30 and 34 biases each frame to the left, where it is inserted into a light beam passing through window 23, and in each track 24 there is a stop (37), Fig. 6 (not shown), which is biased upwards by a spring (54) to retain the frame out of the window. Each stop (37) may be lowered by means of a solenoid to release a selected frame. The apparatus 20 is then moved with the light beam, for example to scan a document to be copied, and when the scan is complete it is returned to its original position by means of a spring (not shown). As it returns, roller 56, which is carried by an arm 57 connected by a spring-biased lost motion connection to an arm 40, engages a cam (55), Fig. 4 (not shown), to turn the arm 40 anticlockwise about pivot 41 so as to engage the arm 50 of whichever filter is in use and return it to the right, where it is retained by stop (37). The operation is then repeated with each of the filters in turn to give, in the embodiment, a threecolour reproduction of a document. The apparatus 20 may also carry with it a lens assembly (15), Fig. 3 (not shown).

Abstract: 1,193,258. Aluminium compounds. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. 31 May, 1967 [9 June, 1966], No. 25839/66. Heading C1A. A hydrated aluminium compound containing nitrate, which can be converted to α-alumina, has a molar ratio of Al: NO 3  of about 1: 0À6. Ammonium ions, in the form of ammonium nitrate, the molar ratio of Al: NH 4  being about 1: 0À15, may also be present. The compound may be prepared by reacting an excess of aluminium amalgam with dilute nitric acid to produce a sol which may be dried to produce a gel. The sol may alternatively be de-watered by contacting it with an immiscible liquid such as 2-ethylhexanol which will extract water. The gel may be de-nitrated by heating at about 500‹ C. Alternatively, the sol may be denitrated directly without the drying stage, by contact with strong ammonia or an amine. The de-nitrated product may be calcined in air at 800‹ to 1400‹ C. to obtain α-alumina. Additives e.g. stabilizers for alumina may be added as nitrates to the sol.

Abstract: 1,074,205. Reciprocating pumps and motors. H. EBERT. June 23, 1964 [July 23, 1963], No.25879/64. Heading F1A. In a pump or motor having a rotary cylinder block with cylinders arranged substantially parallel to the block axis, the cylinder block is tiltable relative to a drive flange, or a swash plate is tiltable relative to the cylinder block, about an axis which is spaced from the cylinder block axis by a distance such that free alternating moments about the pivot axis are prevented and only positive or only negative pivoting moments can be exerted about the pivot axis, thereby reducing vibration during operation. A journal construction for the pivoting member, enabling pivoting in both the positive and negative regions with relatively small adjusting moments being required, provides two alternative pivoting axes E, F spaced from the cylinder block axis, the pivoting member being pivoted about one axis in the positive pivoting angle region, and about the other axis when pivoted in the negative region. The journals each comprise a housing member 414 receiving a pivoting member 430, crescent-shaped filling members 431, 432, being slidably located between members 414, 430 and limited in their movements by stop members 433-436. On clockwise pivoting movement of member 430, stop 436 holds filling 432 stationary and stop 434 moves filling 431 so that pivoting takes place about axis E. On anti-clockwise movement of member 430, stop 433 holds filling 431 stationary and stop 435 moves filling 432 so that pivoting takes place about axis F.
