Title: Rotary pump or motor
IPC: F01C21/08
Filed: 1962-03-01
Abstract: 1,001,087. Rotary pumps and motors. AIM PUMP CORPORATION. March 1, 1962 [Oct. 10, 1961], No. 8069/62. Heading F1F. A rotary pump or motor of the outwardly sliding abutment type, described as a two-stage compressor, comprises a housing 11, Fig.1, formed by cylindrical parts 12, 13, end covers 15, 16 and a divider wall 14 to form cylindrical chambers 33, Fig. 2, through which passes a concentric shaft 17 driven by a pulley 83 to which is secured a cooling fan 85. On the shaft 17 are eccentrically mounted rotors 21, 22, one in each chamber, with their eccentricities 180 degrees with respect to each other. Each rotor is formed with lightening holes 52, and to reduce the off-centre weight of the rotors, an axially extending recess 38, housing a wiper bar 37, Fig. 3, urged by a leaf-spring 39 into sliding contact with the chamber wall 32 and on its end faces 44 with recesses mounting flexible seal rings 43 which are split to straddle the wiper bar. To provide a proper sliding fit for the bar 37, a resilient strip 40 and a metal strip 41 are fitted in the recess 38 at its leading edge. The outwardly sliding abutment comprises a blade 23 guided at its ends in grooves 26, 27 in an end cover and the divider wall and passing with clearance through a slot 35 into a cavity 34 to which pressure fluid at regulated pressure is supplied through a line 78. The pressure fluid acts on sealing plugs 54, 55 mounted in a bore 53 intersecting the slot 35 to urge the blade 23 into contact with its rotor. The plugs 54, 55 each have a flat surface, the one on the plug 54 being exposed to pressure on the high pressure side of the blade 23 and the one on the plug 55 to pressure in the cavity 34 so that the plug 54 is urged outwardly and the plug 55 inwardly. With the build-up in pressure on the high pressure side of the blade 23, the blade is urged outwardly against a spring-loaded plunger 65 just before the bar 37 passes the slot 35 to be free from contact from the bar to be again urged into contact with the rotor by the spring-loaded plunger 65, 72 immediately the bar passes the slot. An air cleaner 86 is fitted on the inlet connection 87 to the first stage, and an intercooler between the stages. Lubrication oil admitted to the chambers 33 through pipes 98 is afterwards separated from the compressed air. Lubricating oil for the bearings is admitted through pipes 99. In a modification, a rocker assembly 110, Fig. 11, having rollers 117 resiliently loaded by springs 113 co-ordinates the movements of the rotors of the two stages. The driving pulley 83 may be counterweighted to balance the off-centre load of the rotors.

Title: Pulsed thermonuclear reactors
IPC: G21B1/00
Filed: 1974-02-22
Abstract: 1432896 Thermonuclear reactors A G FISCHER 22 Feb 1974 [19 Oct 1973] 8179/74 Heading G6P In a thermonuclear reactor, a reaction plasma is created and contained in a mass of molten lithium deuteride enriched in lithium-6 and hydrogen-3, by a discharge of a capacitor. The capacitor 1 is a concentric plate device the plates of which diverge into dome shapes to define a reaction chamber 13. Discharge is controlled by a switch having a movable piston 27. The discharge occurs between the electrodes 3, 4 the tips of which are made of Be to give a neutron-multiplying effect. Deuterium gas is injected, through the lower electrode 4, into the melt 5 continuously: the bubble curtain attenuates shock waves and the convection currents homogenize the melt. The chamber 13 embodies external cooling coils 9 which operate to provide solid LiD layers internally of the chamber. Pulsed operation of the reactor proceeds by repetitive discharging of the capacitor 1, a discharge channel 6 being preformed thermally, prior to each pulse, by an A.C. current passed between the electrodes, the material of the channel 6 forming the plasma. During each power pulse, fission-fusion chain reactions occur and tritium is bled in the liquid

A scale for a measuring instrument carries both a conventional set of spaced graduations and also, by its side, a binary-coded pattern the physical arrangement being such that when the measuring instrument pointer 3a, Fig. 1, is photographed the adjacent coded-pattern 2 will provide a "coarse" indication of the position of the instrument pointer and the position of the pointer with respect to the adjacent scale graduations 4a will provide a "fine" indication. Such a scale is said to be useful for instruments such as theodolites where readings made in the field can be photographed and analysed at a central office. A system for reading "fine" indication on the record shown in Fig. 1 is; described (Fig. 13 not shown) in which by scanning the strips 3 and 4 photo-electrically and synchronously producing clock-pulses pulse counts are produced which represent the distances a and b shown in the Figure. The quotient of these two distances gives the required "fine" measurement.

Title: Improvements in or relating to Non-Dispersive X-ray Analysis
Inventor: CARR-BRION KENNETH GARFIELD
IPC: G01N23/223
Filed: 1966-02-28
Abstract: 1,158,871. Photo-electric X-ray analysis. NATIONAL RESEARCH DEVELOPMENT CORP. Feb.27, 1967 [Feb.28, 1966], No.8729/66. Heading G1A. In the X- (or y-) ray analysis of a slurry to determine a particular element, the slurry is passed through two adjoining analysis chambers, the first being irradiated by a source-target combination 3A, 4A, of sufficient energy to excite the characteristic radiation of the element of interest and the second 2, being irradiated by a similar source-target combination 3B, 4B which is just insufficiently energetic to excite the characteristic radiation. Both source-target combinations also produce a background component of scattered radiation which can be arranged to be substantially equal for the two chambers. By taking the difference between the counts obtained with detectors viewing the chambers in the back-scattered direction the background component is cancelled out, so that the intensity of the characteristic radiation of the wanted element, which is proportional to the concentration of the wanted element in the slurry, is determined. For example, in the analysis of a slurry for its barium content, the primary sources 3A, 3B are conical radio-isotopes of Am 241 emitting 604KeV γ-radiation. The targets are chosen to be of elements of adjacent atomic number and to produce characteristic X-rays having wavelengths on either side of the wavelength of the absorption edge of the element of interest. In the case of barium, targets 4A, 4B are of samarium and barium respectively. The secondary radiation from the sample produced in chambers 1, 2 is converted by respective scintillator crystals 6A, 6B of NaI (Tl) into light which is conducted by guides 7A, 7B to photo-multipliers 8A, 8B, connected to scalers 9A, 9B. Alternatively, the detectors may be proportional counters. Calibration curves are obtained using samples of known barium concentration, Figs. 2, 3 (not shown), having previously equalized the background components (backscattered radiation) from the two chambers by screw adjustment (5A, 5B) of the positions of the sources whilst using a bariumfree sample flow. The invention includes within its scope an arrangement where the targets are irradiated by a common radio-active source.
