Title: A spectrometer including two-speed drive apparatus
IPC: G01J3/06
Filed: 1965-09-22
Abstract: 1,105,169. Programmed process control. APPLIED RESEARCH LABORATORIES Inc. Sept. 22, 1965 [Sept. 22, 1964], No. 40387/65. Heading G3N. [Also in Division F2] A control system for a transmission in an X-ray spectrometer including a main brake and clutch engaged by solenoids 23, 22 and high and low speed gear trains each containing a clutch engaged by solenoid 28, 26, includes a perforated disc movable past a photo-sensor 64 feeding a signal to Schmitt trigger 70. A switch 74 has two manual and two automatic position; in the INTEGRATE position, as shown, bi-stable multivibrators energize solenoids 22, 28; when sensor 64 detects the leading edge of an aperture a signal is fed from trigger 70 to vibrator 72 to de-energize high-speed solenoid 28 and energize low-speed solenoid 26. The signal from trigger 70 is also fed to a vibrator 76 the output of which is adjustable with respect to the duration of the pulse produced; the trailing edge of this pulse causes vibrator 78 to de-energize main-clutch solenoid 22 and energize brake solenoid 23. The trailing edge of the pulse is also fed to integrator 82 which after a certain time produces a signal to return vibrator 78 to its original state and a signal from this vibrator is sent via switch arm 84 to vibrator 72 to return it to its original state. In the PROFILE position of switch 74, a diode 86 is shorted by switch arm 88 so that vibrator 72 is triggered by the leading and training edge of the pulse from trigger 70 to switch from high-speed to low-speed and then back to high-speed; the vibrator 76 is disconnected from trigger 70 so that vibrator 78 maintains solenoid 22 energized.

Abstract: 1,261,990. Detecting interfaces between liquids. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Aug.14, 1969 [Aug.16, 1968], No.40680/69. Headings G1N and G1S. A method of detecting a change in the composition of liquid which is being transported through a pipe-line 9 comprises measuring simultaneously the pressure drops across two spaced apart sections 10, 15 in the pipe-line, a change in the difference between the two pressure drops indicating that an interface separating liquids of different compositions is passing through one of the sections. Differential pressure gauges 11, 16 are connected to the pipe-line via lines 12, 13 and 17, 18, the lines 13, 18 being filled with a reference liquid which is separated from the liquid in the pipe-line by diaphragms 14, 19. The gauges are placed in covered pits 20, 21 to minimize the effects of temperature changes and are connected to a common power supply 22 and rheostats 25, 28. The voltages developed across the rheostats are subtracted in a differential amplifier 29 connected to a zero adjustment device 30, a filter 31 for removing signals not associated with the passage of an interface and a recorder 32.

Abstract: 1354758 Continuous casting CONCAST AG 2 Sept 1971 [4 Sept 1970] 41101/71 Heading B3F In a secondary cooling zone, a continuous casting 5, Fig. 3, descends in the direction 18, Fig. 2, between opposed guiding and supporting elements 3(3<SP>1</SP>) with a grid of surfaces 10 which contact the casting surface and surround openings 11 through which nozzles 8 direct sprays of water on to the exposed surfaces of the casting 5. The guide surfaces 10 wipe the water from the casting surfaces as they pass. Where less support is required, e.g. near the edges of a slab casting and a guide surface may be omitted so that the resulting enlarged opening has at least two sprays through it. The elements comprise cast iron plates 30, 30<SP>1</SP> secured to a frame 31 on a framework 24 and the spacing between opposed plates is adjustable by means of hydraulic rams or bolts, Fig. 4 (not shown). The surfaces 10 may be in a lattice-like form, Fig. 5 (not shown). The openings 11 may be circular or elliptical or those nearest the reciprocated mould (to which the plates may be attached) may be transverse slots. Hinged deflector plates (in place of the guiding elements) are used at the narrow sides of a cast slab, to shed the water. As indicated in Fig. 3, the spray nozzles 8 are mounted in the openings 11 which have inclined lower boundaries 21 which lead the used water away to the rear and to drain ducts 23. Instead of each sprayed area corresponding generally to the size of the opening, a narrow region 20 at the bottom may be clear of the spray. The casting 5 is withdrawn by a straightening machine, from an arcuate guideway with rollers succeeding the guiding elements (3, 3<SP>1</SP>).

Eccentric control rings 20 are mounted on fixed bearings and engage the ends 17 of the holders 15 by means of driver pins 22 whereby the required orientation of the knives 14 is maintained during carrier rotation. The knife feed is driven on rotation of the carrier from gear wheels 27 mounted on the driver pins 22, the driver including a train of gear wheels, worms and worm wheels which causes pins (52, 54, Fig. 6) to act on the rear edge of the knife 14. The knife 14 is releasably clamped by a plate (55, Figs. 6-8) the latter being acted on by an eccentrically pivoted clamping lever (57) with an actuating lever (64).

Abstract: In the synthesis of urea from ammonia and carbon dioxide, off-gases are recovered from the urea product stream by reducing the pressure and with heating, gaseous carbon dioxide is added to the recovered off-gases and the combined gases are adiabatically compressed to urea synthesis pressure after which ammonia is added and the gases passed to urea synthesis. If the off-gas is generated in a plurality of stages at successively reduced pressure levels, the gaseous carbon dioxide is suitably added, prior to compression, to the fff-gas stream recovered from the last stage of the multi-stage recovery, which is at the lowest pressure, and each off-gas at each level is adiabatically compressed and added to the off-gas at the next higher pressure level.
