Title: Apparatus for the removal of water from sewage sludge by evaporation and drying
IPC: C02F11/13
Filed: 1955-04-04
Abstract: In apparatus for removing water from sewage sludge, comprising a multiple-effect evaporator for concentrating the sludge, one or more driers for drying the concentrated sludge and one or more pre-heaters for the fresh sludge, means are <PICT:0806699/III/1> provided for connecting any one of the evaporators to a boiler for raising steam and for taking out of service any other evaporator so that the concentrated sludge therein can be transferred to a drier.  The driers are supplied with steam evolved from the sludge in one of the evaportors; and the steam evolved in the driers is used for heating the pre-heaters.  The system shown comprises pre-heaters 21 and 21a, a number of evaporators 3, 3a ... 3n of the shell and tube type, two driers 19, 19a, and a boiler 1.  Sludge to be treated is supplied to the evaporators through conduits 6, 6a ... 6n.  Steam from boiler 1 is introduced through conduit 2 into the tubes of evaporator 3; and the steam-condensate is discharged through conduit 4 to heat exchanger 5 where it pre-heats the sludge flowing through conduit 6. This pre-heated sludge passes through gas separator 8, and is then sprayed into the upper part of evaporator 3.  This spray of fresh sewage breaks down foam in the lower part of the evaporator, and diminishes the entrainment of solids in the steam leaving the evaporator.  This steam passes through purification vessel 14 where entrained water and solids are separated, and then returned to evaporator 3 via conduit 16.  The purified steam from vessel 14 is used as heating-medium for evaporator 3a.  The steam generated in evaporator 3a is purified and is introduced into the tubes of the next evaporator.  The purified steam from the last evaporator 3n is passed through conduit 18 to driers 19, 19a.  After a predetermined period of time each evaporator in turn is taken out of service by manipulation of the appropriate valves 2a and 2b; and the concentrated sewage is withdrawn through conduit 24, 24a ... or 24n, and transferred to the driers.  The steam driven off from the sludge in the driers is used to pre-heat fresh sludge in pre-heaters 21, 21a, and to pre-heat boiler feedwater in pre-heater 26.  The empty evaporator is refilled via conduit 25 with pre-heated sludge from pre-heaters 21, 21a.  After the sludge has been sufficiently dried, the solids are removed and replaced with concentrated sludge from the next evaporator of the series.

Title: Improvements in or relating to the treatment of refuse in refuse destructors and theproduction and treatment of a fluid slag obtained therefrom
IPC: F23J1/00
Filed: 1919-10-11
Abstract: 149,033. Kershaw, J. B. C. Oct. 11, 1919. Stone, artificial.-Slag containing 40 per cent of silica and 15 per cent of lime and magnesia is obtained by burning refuse in a refuse destructor with lime-containing material such as limestone chemical waste or road sweepings, 100 tons of refuse being mixed with 8 tons of limestone or its equivalent of lime-containing material before being charged into the destructor. Low grade carbonaceous material such as slack, coke breeze, peat or wood refuse may also be added to the refuse. The slag produced may be run from the destructor into moulds to form building-blocks and slabs or articles of any desired shape. Preferably the slag is run into a series of iron moulds formed by moulding-pieces placed on edge on the ground, the moulding-pieces having thickened ribs at the corners to strengthen them and leave air spaces between the adjacent sides when placed in rows. The slag may be treated in its molten condition with superheated steam by allowing a steam jet to play on the slag and thus reduce it to a fine amorphous powder ready for use in the mixing of cement or mortar. The slag may be also granulated by passing it into a jet of cold water.

Abstract: 641,652. Automatic control systems for aircraft. GLENNY, A. P., and SPERRY GYROSCOPE CO., Ltd. April 14, 1947, No. 9888. [Class 38 (iv)] In a craft automatic control system, in which a control surface is operated by a servomotor from a reference instrument, a manual switch in its first position renders the system effective up to the valve controlling the servomotor, and energizes an indicating device showing the state of the system, while in its final position the system directly controls the servomotor. As shown, the pneumatic servomotor 24, which positions the control surface, is operated from the gyro-vertical 1 through the electrical relay 12 and selector valve 20. The flow of air from 20 to 24 is controlled by the byepass valve 26. To place the automatic system in control, the switch 37 is moved to position B, whereupon the valve 20 is positioned by the gyro 1 and if the piston of the valve is not in its neutral position, air is ejected from either of ports 27, 27<SP>1</SP> and the consequent unbalance of the bolometer bridges 35, 35<SP>1</SP> is indicated by the lighting of one or other of lamps 36, 36<SP>1</SP>. The piston of 20 is centralized by an adjustment of potentiometer 9, lamps 36, 36<SP>1</SP> are extinguished and switch 37 is moved to the final position when the solenoid 34 closes ports 27, 27<SP>1</SP> and the valve 20 directs the air supply to the motor 24. Abrupt changes in course, upon a change from manual to automatic control are eliminated. Specifications 631,470 and 636,328 are referred to.

[Class 4] For testing parts of undercarriages, particularly the shock-absorber, the part is mounted on a beam which is accelerated to the required velocity at which impact with the ground is supposed to take place. As shown the beam consists of a paralelogram 4, 5, 6, 7 of which the sides 4, 5 are pivoted on transverse shafts 2, 3. Masses M 1  and M 2  are mounted on the side 6 and, through a bracket 8, upon the side 7 to simulate the inertia of the aircraft, the shock-absorber leg 9 also being mounted on the bracket 8. Elastic cables 14, 15 accelerate the beam to the required velocity when a detent 20 is displaced, the acceleration ceasing before the landing wheel hits a plate 21 connected to dynamometric apparatus. The plate 21 may be laterally tiltable to simulate skid landings, or it may be replaced by an irregular-surfaced movable belt. By varying the relative weights of the masses M 1 , M 2  the beam may be given an additional acceleration or a retardation after the elastic cables have ceased to act upon the beam. Fluid pressure or explosive devices may be used instead of the elastic cables 14, 15.

Title: Elastic boundary wave device
Inventor: ISOBE ATSUSHI
IPC: H03H9/25
Filed: 1994-01-11
Abstract: PURPOSE:To make a temperature characteristic excellent, to reduce insertion loss and to make productivity excellent by forming a SiO film on a theta deg. rotation Y-cut tantalic acid lithium single crystal substrate and defining the thickness of theta and SiO2 films as a specified condition. CONSTITUTION:In the SiO2 film 12 thickness dependency of the propagation speed of the elastic boundary wave BAW in a SiO2/theta deg. rotation Y-cut Xpropagation tantalic acid lithium single crystal piezoelectric substrate, the SiO2 film 12 thickness (h) is standardized by a BAW wavelength lambda (electrode cycle) and a cut angle 8 is made 100<theta<124 or 128<theta<150. Because the dispersion of transmission speed is proportional to the dispersion of a center frequency when products are mass-produced, the small change of propagation speed for the dispersion of the SiO2 film thickness is significant to improve a good item ratio. When the BAW is used, as the SiO2 film is thickened by any theta, the change of propagation speed becomes small. When the dispersion of the film thickness at the time of the preparation of the SiO2 film is 15%, the dispersion of the center frequency of products can be made below 0.15% by setting h/lambda>1. Therefore, a temperature characteristic is made excellent, insertion loss is reduced and productivity is made excellent.

Abstract: PURPOSE:To improve the deterioration of filter characteristics due to the distortion of wave surface, by using a short-circuit electrode as a split electrode. CONSTITUTION:Surface elastic waves propagate from the center of the surface elastic wave exciting electrode B or C to the direction crossing the electrode fingers 1-16 and 1'-16'. In this case, the disturbance of wave plane can be less if the total of the electrode finger width (g) crossing them is equal at any cross section. Thus, to the gap length (l) with electrode fingers 4, 4' the provision of a short- circuit electrode (d) with the split electrode for the electrode fingers 5 and 6 at the  position in parallel movement transversally for the gap length (l) can cover the  gap (l). It is preferrable to provide the short-circuit electrode (d) corresponding to  the split electrode very near the gap of the electrode finger. Thus, the provision of  the short-circuit electrode (d) is that the wave surface propagating any part of the  electrode fingers 1-16, and 1'-16' passes through equal electrode finger width in  total, allowing to avoid the disturbance of the wave surface.
