Title: Improvements to spectroscopic apparatus
IPC: G01J3/42
Filed: 1958-11-25
Abstract: 909,833. Photo-electric spectrometers. PERKIN-ELMER CORPORATION. Nov. 25, 1958 [Nov. 25, 1957], No. 37853/58. Class 40 (3). In a comparison spectrometer the intensities of the measuring and comparison beams are controlled so as to maintain the sensitivity of the instrument constant. As shown, two beams of radiation RB, SB, pass respectively through a test chamber 21 and comparison chamber 14 and are directed alternately through a slit 19 by a disc 20 which interrupts beam RB and reflects SB. The beams then pass to a concave mirror which reflects them to a dispersing prism 24 and Littrow mirror 25 after which they are chopped by a motordriven interrupter 39, redispersed and directed through a slit 30 to a radiation responsive device 32. Choppers 20 and 39 are 90 degrees out of phase so that the output of device 32 is as shown in Fig. 2 (c). This output is applied to phase-sensitive demodulator 34 together with double frequency reference, Fig. 2 (d), to produce an output, Fig. 2 (e), which contains a D.C. voltage representing the difference between the intensity of the two beams and is free from interference by light which has been twice dispersed. The output of device 32 is fed to a further demodulator 34a which is controlled in phase with the second interrupter 39. At the output of this demodulator is produced an alternating voltage, Fig. 2 (g), containing in the balanced condition of the device a direct component proportional to twice the value of the measuring beam. This voltage is amplified at 34b by a factor dependent on the position of the balancing wedge to give a signal indicative of the intensity of the comparison beam which is used to adjust slit 19 to adjust the intensities of both measuring and comparison beams.

Abstract: 1526128 Breaking of rock by incompressible fluids INSTITUT CERAC SA 20 Sept 1976 [19 Sept 1975] 38849/76 Heading E1F [Also in Division B5] A method of breaking hard compact material, e.g. rock, comprises drilling a blind hole into the material, generating by a nozzle located in alignment with the hole a high velocity jet of relatively incompressible fluid, e.g. water, and directing the jet into the hole so that it is stopped by the bottom of hole to create a pressure in the hole of sufficient magnitude and duration or jet repetition rate to break the material towards its free surfaces adjacent the hole. Preferably the depth of the hole is 5 to 10 times its diameter and may be partially or wholly filled with an incompressible fluid, e.g. water, prior to the generation of the jet. The hole may be drilled mechanically or by either a single jet or a sequence of jets to which increasing energy and velocity is imparted when fracturing of the rock surrounding the hole is required. The nozzle has a circular cross section outlet through which emerges the high velocity jet required by the method and a secondary outlet for supplying said fluid to fill the hole. Preferably the second outlet is disposed annularly around the primary outlet so that the hole-filling fluid is emitted as a shrouding fluid about the high velocity jet for muffling the sound generated by said jet.

Class 100(2) In an inking device for aniline printing- machines, for adaptation to opposite directions of travel of the paper, the doctor blade is designed to be brought into contact with either the upper or the lower part of the screen fountain roller as desired, the ink being taken from the trough by the roller when the blade is in the upper position and being supplied to the doctor from above when the blade is in the lower position. In the upper position of the blade 5, Fig. 1, the roller 4 is partly immersed in ink in the trough 6. By releasing a screw connection with its spindle, lowering the trough, removing the blade and replacing it the other way round, the blade can be brought into the lower position, Fig. 2. In this case, ink from a reservoir 10 is supplied by a pump 9 through a pipe 11 to the middle of the blade 5, runs down the sides of the blade into the trough 6 and thence through a cock 12 and flexible pipe 13 back to the reservoir.

Abstract: 1478189 Charging coke oven chambers KOPPERS CO Inc 9 Sept 1974 [9 Oct 1973] 39340/74 Heading F4B A coling chamber 13 in a coke oven battery 11 has two gas off-take passageways 15 and 17 adjacent two outer charging holes 19 and 23 and an intermediate off centre charging hole 21. The flare angle of each charging hole is about 55‹. The outer charging holes 19 and 23 are associated with coal hoppers 27, 29 provided with screw feeders 33 and drop sleeve conduits 35, and the centre charging hole 21 is associated with a gravity discharge hopper 31. For charging the oven chamber 81% by volume of the coal required is discharged simultaneously from hoppers 27 and 29 through screw feeders 33 resulting in coal masses 73 and 71 and no blocking of the gas off-take openings 15 and 17. The remaining 19% of coal is then discharged by gravity from hopper 31 resulting in coal mass 75 which blocks the charging hole 21. Coal in the chamber is then levelled to the line 77. For charging an oven chamber having four charging holes with flare angles as above, 78% of the charge is screw fed from hoppers to the outermost charging holes, about 9% is fed to an intermediate charging hole and the final 13% is fed to the other intermediate charging hole giving the distribution in Fig. 6.

Abstract: 1,160,408. Reactor pressure vessels. GULF GENERAL ATOMIC Inc. 30 Aug., 1967 [7 Sept., 1966], No. 39687/67. Heading G6C. To prevent leakage of coolant through openings provided in a reactor pressure vessel, each opening is closed by a pair of seals arranged in tandem and defining a region therebetween which is continuously maintained at a pressure higher than that of the coolant in the pressure vessel. Two embodiments are described with reference to drawings (not shown) relating to a gas-cooled reactor having a concrete pressure vessel. In one embodiment the openings comprise refuelling standpipes and in the other the opening serves for mounting a gas circulator. The higher pressure is obtained by a compressor having its intake connected to the reactor coolant circuit and its output connected to the region between the two seals, the compressor boosting the pressure by about 5 p.s.i.
