Title: Improvements relating to densitometers
IPC: G01N9/30
Filed: 1964-10-20
Abstract: 1,024,585. Densitometers. ROTRON MANUFACTURING CO., INC. Oct. 20, 1964 [Feb. 4, 1964], No.42773/64. Heading G1S. A densitometer for measuring the density of gas in an enclosure comprises intake and discharge passages which are arranged to be put in communication with the enclosure, a rotary impeller 91 surrounded by a number of involute discharge passageways 125 which have open apices, means for rotating the impeller at a predetermined constant speed so that gas is drawn by the impeller from the enclosure through the intake passage and intake manifold 115 and is. discharged through the involute passageways into a collector system and out through the discharge passage back to the enclosure, and openings 139, 137 at which the pressure differential between the intake and discharge passages can be measured. The densitometer comprises three main units, the driver, the sensor and the service valve. The driver comprises a motor driven shaft 38 (not shown) which is connected by a pulley system to a shaft 68. The driver case is sealed from the sensor to prevent heat exchange and to allow for changing the driver unit. The shaft 38 has fan blades which draw air into the motor casing for cooling purposes, the air being drawn through a filter unit 80 (not shown) which also has a blow out liner so that any build up of pressure within the sensor can escape into the atmosphere. The shaft 68 supports a driver coupling magnet 77 providing one half of a magnetic coupling, the other half, the driven coupling magnet 98, being mounted on the impeller driving shaft. Thus the shaft 38 transmits its rotational movement to the impeller 91. The impeller 91 is disposed between surfaces 123a, 123b of facing end plates 108, 110 and is so shaped that gas can pass through the impeller eye 91b, past blades 91c and out of a series of radial slots 91d. Around the impeller are discharge involutes formed in grooves 121a, 121b in the end plates 108, 110, the involutes terminating in outlets 125 which direct the gas into a discharge plenum 136a formed in the discharge manifold 116 and connected to the pressure chamber 136b by small openings 137. The static pressure in the discharge pressure chamber 136b is measured at the manometer connection 146 before the gas is fed back into the pipe line. The inlet pressure is measured at the manometer connection 148 which is connected to the inlet pressure chamber 138 which has openings 139 into the inlet plenum 126. The difference in these two pressures provides a measure of the density of the gas; the apparatus is calibrated by varying the position of six swirler blades 128 mounted in the inlet plenum. Different density ranges require different speeds of the impeller shaft which is accomplished by changing the driver unit. The service valve unit comprises two parts, a top disc 151 and a bottom disc 152 with ball valves 171, 170 (see Fig 6, not shown) such that in one position a continuous passage is provided between the pipe line and the sensor, and in the other position the gas flow is cut off to permit removal of the sensor.

Title: Improvements in Hydraulic Systems
Inventor: DUCKWORTH PETER
IPC: F15B11/22
Filed: 1965-10-21
Abstract: 1,157,291. Press-brakes; shearing. SPERRY RAND Ltd. 27 Sept., 1966 [21 Oct., 1965], No. 44604/65. Headings B3E and B3W. [Also in Divisions B5 and F1] A system for causing double-acting hydraulic jacks 1, 2 to move in unison in either direction for operating, e.g., the blade of a shearing and bending machine, comprises coupled reversing valves 3, 4 for the jacks and a control valve 9 controlled in response to the difference in displacement of the jacks to vary the flow to the jacks so as to reduce the difference in displacement, each valve 3 or 4 controlling in one position the advance of one jack and in its other position the withdrawal of the other jack. When the valves 3, 4 are first changed over by simultaneous energization of associated solenoid valves, and assuming the jacks are only lightly loaded, a large flow low pressure pump 7 supplies the jacks through a flow-divider 12 and the control valve 9 proportions the flow to the jacks from a low flow high pressure pump 6. If the load on the jacks increases, pressure builds up in a pilot line 11 to cause a valve 10 to open and by-pass the output from the low pressure pump 7. The jacks are then operated solely by the pump 6, non-return valves 13, 14 preventing return flow through the flow-divider 12. Two arrangements for detecting the difference in displacement of the jacks and controlling the valve 9 are described. In the first, Fig. 2 (not shown), each jack piston causes rotation, through rack-and-pinion gearing, of a shaft. The shafts are connected through a screw-andnut connection, whereby differences in their rotation cause axial movement of the nut and consequential adjustment of the valve 9. The second arrangement, Fig. 4 (not shown), comprises two drums each driven by a cable connected to the jack piston, the movements of the drums being transmitted to a differential rotary servo valve providing an hydraulic output for adjusting the valve 9.

In operation the main die 26, Fig. 3, face plate 35 and die holder 10 are secured to the extruder by jack screws (not shown) so that the die opening 27 and aperture 27<SP>1</SP>, Fig. 1, are concentric with cable 15. If die opening 32 is not coaxial with strand 16 it is adjusted radially by rotation of an eccentrically mounted member 42 which passes through a slot 43 in die 30. If a circumferential movement of die 30 is necessary, screws 36 which secure face plate 35 and die members 26 and 30 to die head 10 and which pass through enlarged openings 37 are loosened, and main die 26 and plate 35 are rotated by rotation of a second eccentric actuator 52. Normally the offsetting of die openings 27, 27<SP>1</SP> due to this movement may be ignored. If finer adjustment is needed the whole of the adjustment procedure is repeated.
