Abstract: 749,333. Ultrasonic inspection devices. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. March 4, 1954 [March 6, 1953], No. 6326/54. Class 118(2). A pipe 1 is tested for internal faults by partially immersing it in a tank 4 full of liquid and arranging an ultrasonic transmitter 5 and receiver 8 in the liquid so that ultrasonic waves traverse the unimmersed portion of the pipe by multiple reflections between the inner and outer surfaces of the pipe, the presence of a flaw 9 causing a diminution of the received waves. When the pipe extends beyond the ends of the tank, each end comprises a portion of compressible material, e.g. felt or rubber, having a semi-circular notch (Fig. 2, not shown) so that the pipe can be moved axially or helically through the tank.

Title: A process and an apparatus for separating solids from a gas
IPC: B01D45/12
Filed: 1968-02-09
Abstract: 1,214,872. Separating solid particles from gas; cyclone separators. DEUTSCHE GOLDUND SILBER SCHEIDEANSTALT. 9 Feb., 1968 [11 Feb., 1967], No. 6439/68. Headings BIT and B2P. Solid particles are removed from gas, in chemical plant, by passing the gas through cyclone separators 1, 2, 3, which operate in series, then through filters 4, 5, 6, which operate in parallel, each filter comprising a plurality of outward-flow filter tubes which are cleaned periodically by reverse flow of filtered gas, drawn from outlet manifold 12 by blower 15, after closing valve 10a, 10b or 10c and opening valve 4f, 5f or 6f a short time later. During the changeover of each filter from filtering to reverse flow and back, a valve 19 is opened and gas flows through conduit 17, a valve 18 creating the same pressure drop as would a filter on reverse flow. This arrangement limits pressure surges which might damage the filter tubes or chemical plant upstream of the cyclones. Blower 15 delivers the reverse flow gas and the agglomerated solids from the filter tubes to the upstream side of cyclone 2 where they attract fine particles to assist the separation in the cyclone. Alternatively (Fig. 2, not shown) the blower may deliver the solids into an agglomerator (7), in series between two cyclones, in which the same process occurs. Agglomerator (7) may be a mechanical whirler or use electrostatic or ultrasonic effects. The filter tubes are glass cloth and held under tension by adjustable upper fastenings. Synthetic fabrics and fabrics impregnated to resist heat and/or chemicals are mentioned. The cyclones, filters and connecting conduits are all heated by means 20, 21 to prevent condensation.

[Also in Division B7] To provide protection against adverse weather conditions for a tractor driver, the tractor has a system for providing air in the vicinity of the driving seat, which is provided with means for forming a downwardly flowing curtain of air in front of the seat. The driving seat 30, is provided with a protective canopy having side walls 71 equipped with windows 78 and a rear wall 70 and, together with a platform 81 upon which are mounted control pedals 82 and 83, is mounted for rotation upon a tubular shaft 32 supported on thrust bearings 34 located in a chamber 21, at the upper end of which the tube makes air-tight contact and on the top of which is provided a series of locating holes which may be engaged by a locking pin 42. The air circulating system comprises an intake member 8 connected by a duct 9 to a chamber 10 in which are located a fan 12 and a radiator 19, and from the side of which opposite to the fan, a duct 20 leads to the chamber 21, under the control of a valve 22, provided with holes through which air may be vented to atmosphere. Air enters the shaft 32 through holes 44 and from the top of shaft 32 extend ducts 50 and 51, a control valve 46 being provided. The duct 50 leads to a discharge member 52 (Fig. 5), for directing air to the vicinity of the driver's legs. The seat 30 is surrounded by a member 54, formed below and at the sides of the seat as duct members 55 and 56 connected by slots 57 (Fig. 2), with the duct 51 and controlled by valves 66 and 67 (Fig. 5), the duet members 55 and 56 having openings 58 and 59 whereby air is directed towards the driver's elbows and hands. The canopy is detachably mounted on the member 54 and has a strengthening rib 72 formed as a duct registering with the duct 51. Holes 77 are formed in the dutc 70, directing air towards the driver, and the duet 70 terminates in a chamber 75 having an opening 76 whereby a curtain of air is downwardly directed in front of the driver. In an alternative arrangement, air used to cool the lubricating oil may be used, or in a tractor having an air-cooled engine, the air used for cooling the engine may be used in the system, or an arrangement may be provided which directs unheated air through the system. A plastic cover 84 may be provided for the driver's legs.

A fuel injection pump has a vane type feed pump 5 feeding fuel to a bore containing opposed pistons, via a metering valve 14. The angular setting of the cam ring 15 varies with the pressure in the passage inconnecting the feed and injection pumps at a location between the metering valve 14 and a restricted orifice 13. The pressure is proportional to the speed and the load on the engine and acts on a spring loaded piston 19. The piston 19 may be stepped (Fig. 4, not shown) and the pressure upstream of the orifice 13 fed to the smaller diameter end of the piston, upon which the spring acts, whereby the effect of speed variation on the injection timing is reduced.

Title: Method and system for drying gases

Abstract: 1,039,943. Drying gases. McGRAW-EDISON CO. Feb. 17, 1965 [May 28,1964], No. 6819/65. Heading B1L. Gas to be dried is first heated and passed through one of two adsorbers 10 and 12, which contain material such as activated alumina, to reactivate the adsorber before being passed through the other adsorber to be dried, control means reversing the role of the adsorbers and the flow to the adsorbers when predetermined conditions occur in the adsorber being reactivated. With the valves 13 and 14 in positions as shown gas entering through 16 passes through heater 15 and valve 13 to adsorber 12 to reactivate it, and then passes through cooler-condensor 17 and separator 19, where moisture condensed is tapped off to trap 21 to adsorber 10. When a first quantity of gas has flowed through adsorber 12 the rise in temperature is sensed by T3 which turns off heater 15, unheated gas continuing to flow as before. When adsorber 12 has cooled to a predetermined operating temperature by unheated gas flowing through it thermostat T2 energizes a solenoid M2 which causes valves 13 and 14 to shift to their alternative positions, so placing adsorber 12 in drying service, and the reactivation of adsorber 10 begins. During the shifting, limit switches L13<1> and L141 close momentarily to energize coil HR which turns back on the heater and heated gas flows through adsorber 10 to reactivate it until T3 again operates to turn off the heater. After cooling solenoid Ml causes valves 13 and 14 to return to their former position, so giving a continuous drying system.

[Class 39 (i)] In a velocity modulation electron discharge tube of the kind in which the electron beam is projected successively through two resonant chambers separated by a drift space in which bunching of the electrons occurs, the beam is projected through grids occupying circular openings in the resonators and is of hollow form having a wall thickness not exceeding one-tenth of the operating wave length, so that the central portions of the grids are not traversed by the electrons. This ensures that the modulating field strength does not vary by more than 5 per cent over the whole cross section of the beam, so affording sufficiently uniform velocity modulation for satisfactory bunching. The tube shown comprises a cathode having an annular emitting surface 21 providing a hollow electron beam of the desired radial thickness which passes through grids 12, 13, 16, 17 associated with resonant chambers 11, 15 and a drift tube 14. The tube may be used as an amplifier, or as an oscillator by connecting the leads 20, 22 to the chambers 11, 15.
