Title: Radiation detector
IPC: G01T1/164
Filed: 1975-05-07
Abstract: 1513792 Radiography GENERAL ELECTRIC CO 7 May 1975 [15 May 1974] 19156/75 Heading H4F [also in Division H1] An arrangement for determining the x y coordinates of a pulse of light produced in response to radiation includes an array of photosensors each having a non-planar photocathode so shaped that its output is substantially independent of the spacing between the photocathode and the source of light. The photosensor outputs are used to generate electrical signals which represent the coordinates and which vary approximately linearly with the magnitude of the coordinates. The arrangement forms part of an assembly used, for example, to detect gamma rays, X-rays, or positrons, emitted from a patient treated with a radiation-producing substance. The photosensors are arranged in an array, for example a hexagonal array comprising a central photosensor surrounded by one or two rings of photosensors. The axes of the photosensors are parallel, and their photocathodes may be part-spherical and may have an hexagonal periphery to allow close packing, Fig. 7 (not shown). The apex of each photocathode is close, e.g. 0À4-0À1 times the diameter of the sensor face, to the exit face of a scintillator 11, e.g. sodium iodide, which receives the radiation via a lead collimator 10 or other means providing a collimating effect, Fig. 9. The ends of the photosensors are received in mating cavities in a glass or plastics block 15. The photosensor outputs are used to derive signals indicative of the x, y co-ordinates of a light pulse in the scintillator by reference to the total scintillation energy resulting from the pulse at each photosensor. In dependence upon the scintillation energy a z signal is generated. The x, y and z signals pass to a display, e.g. a storage oscilloscope, on which an image corresponding to the scintillations is built up. The z signal may alternatively trigger an analog-digital converter to obtain a digital recording. If the array comprises two rings of photosensors the outer ring may have planar photocathodes, the axes of these photosensors being inclined towards the axis of the array.

Title: Improvements in or relating to fluid-flow-controlling valves
Inventor: RODGER ROBERT COCKBURN
IPC: F16K1/228
Filed: 1959-06-06
Abstract: 907,476. Valves. COCKBURNS Ltd. Sept. 6, 1960 [June 6, 1959], No. 19412/59. Class 135. In a butterfly valve of the kind in which the plane of the butterfly makes an acute angle with the axis of a shaft on which it is mounted, and in which sealing between the butterfly and its seating is effected by an inflatable sealing member, an operating means for the valve is arranged automatically to inflate and deflate the sealing member as the butterfly is moved towards or away from the closed position. The shaft 3 of the butterfly 1 is operated through a bell-crank 7 movable between stops 8, 26 by an operating rod 5 which has a spring connection 10 with the bell-crank. After the bell-crank 7 has moved against stop 8 to close the valve, further movement, of rod 5, enables an extension of this rod to move a lever 14, one end 16 of which acts through a spring 24 on a rod 17 carried by a diaphragm 18. A fluid chamber 21 enclosed by this diaphragm has an opening 22 connected to conduits 23 on the valve body 2 which communicate with an inflatable sealing ring 4 carried in the bore of the body and cooperating with the butterfly 1 so that this movement of the diaphragm inflates the ring 4. Conversely, on opening the valve, the inflating pressure is relieved. The sealing ring 4 may be corrugated and may be of rubber or a metal such as stainless steel.

Patent GB-602238-A (GB)
Title: An improved manufacture of organic mercaptans and sulfides
Filed: 1944-10-10
Abstract: Mercaptans and sulphides are prepared by treating an olefinic material, viz. hydrocarbons or halogenated hydrocarbons containing one or more aliphatic double bonds, with hydrogen sulphide in the presence of a Friedel-Crafts' catalyst, either the catalyst or the olefinic material being pretreated with hydrogen sulphide before the catalyst is contacted with the olefinic material.  The catalyst may be pretreated with hydrogen sulphide before adding to the reaction mixture or may be added while hydrogen sulphide is bubbled through the liquid olefinic material. The olefin is preferably in the liquid phase, temperatures from somewhat above normal, say 90 DEG  C., down to -80 DEG  C. being used, and atmospheric pressure or above. Suitable catalysts are halides such as chloride or bromides of Al, Sb, B, Sn, Ti, Zn, In, mixed halides, oxyhalides, hydrated halides or complexes with alcohols or ethers, hydrogen fluoride, and aluminium amalgam.  The use of stannic chloride is covered in Specification 602,303.  The olefinic materials include primary, secondary, and tertiary olefines, e.g. isobutene, octene-1 or -2, trimethyl ethylene di-isobutene, copolymers of iso- and n-butenes, diamylene, tri- and tetra-isobutene, turpentine, and caprylene, polyolefins such as butadiene, isoprene, 2-methyl pentadiene, and myrcene, and mixtures derived from cracked petroleum and the hydrolysis of acid extracts of C4 cut.  The liquid olefin may be contacted in a packed column with hydrogen sulphide gas containing a gaseous catalysts such as BF3 or HF.  Non-gaseous catalyst may be dissolved in a solvent such as methyl or ethyl chloride or higher boiling halides, nitrobenzene, carbon disulphide, aliphatic or aromatic hydrocarbons, and the solution treated with hydrogen sulphide.  The products may be steam distilled or fractionated and the mercaptans extracted with alkali. They are of use as modifiers in the preparation of synthetic rubber and as corrosion preventives in lubricants.  In examples: (1) and (2) di-isobutene is dropped down a packed glass tube down which is passed a stream of H2S and BF3, and di-isobutyl mercaptan recovered from the product; (3) H2S and BF3 are bubbled into di-isobutene in a batch operation; (4) or (5) the apparatus of (1) is used for isobutene which is condensed by external cooling, tertiary butyl mercaptan being obtained; (6) diamylene is converted similarly; (7) to (14) tri-isobutene, turpentine, tetraisobutene, caprylene, cyclohexene, dipentene, 2-methyl pentadiene, and allyl bromide are treated with H2S and BF3 to yield the corresponding mercaptans, allyl bromide, for example, giving a -bromisopropyl mercaptan.  In the case of 2-methyl pentadiene temperature rises to 125 DEG  C.; (15) hydrogen sulphide is bubbled into di-isobutene while sprinkling in aluminium chloride; (16) the catalyst, chloride of Al Sb, Zn, or Ti or HF, is added to CS2 and H2S bubbled in, di-isobutene then being slowly added. Specification 532,676 also is referred to.

Abstract: 1,035,021. Circuits employing bi-stable magnetic elements. HER MAJESTY'S POSTMASTER GENERAL. May 14, 1963 [May 23, 1962], No. 19890/62. Heading H3B. [Also in Division G4] In a selecting circuit using a plurality of rows of cores of rectangular hysteresis loop magnetic material to which are applied several inputs, a particular input is always selected in preference to any other input which may be present simultaneously by providing on each core in every row disabling winding means which are energized to disable the core when an input is applied to the input winding of each core of higher precedence. The selector circuit of Fig. 2 is designed to select one of four inputs and comprises a matrix of rows and columns of cores, the latter being normally biased to the "0" state by current from batteries B1-B4 through resistors R1-R4, a winding on each core in the row, diodes D1-D4 and a secondary winding of transformer T1-T4. The bias current is removed one row at a time by pulses SP which reverse bias the diodes D1-D4. Each core has associated with it an input and an output winding 3201: 3, 5: 7 and 3202: 4: 6: 8 respectively connected in columns and arranged so that the input signal switches the core to its " 1 " state when the bias current is removed. In accordance with the invention each row of cores has associated with it further bias windings arranged and connected so that a core in a first column is biased by current in any other column, a core in a second column is biased by current in any column other than the first and second columns and so on. The bias current is arranged always to exceed input current and when one or more inputs occur during removal of the current in the bias windings only one core can be driven to the "1" state because of the effect of the further bias windings connected to the input leads. Thus core C14 is biased by currents in input leads 3201, 3203, 3205, core 13 by current in input leads 3201, 3203, core 12 by current in input leads 3201 and core 11 is not biased by any current in an input lead. Thus input lead 3201 takes precedence over all others, lead 3203 over all but 3201 and so on. The order of selection is made different for each row.

The circuit Fig. 2 and waveform diagram F14 are similarly numbered and substantially selfexplanatory. The points of intersection of the attenuated, half-height, stretched pulse 28' with the delayed pulses 26', 30' are detected by comparators C 1 , C 2 , to produce rectangular pulses 36', 38', which are integrated at 40, 42. The attenuated, half-height, integral 44' is compared with the integral 42' in comparator C3 to strobe the centerpoint of the delayed pulse 30'. Modifications:- (i) comparator C2 may be replaced by a delay circuit to produce pulse 38' from pulse 36' Fig. 3 (not shown). (ii) Points other than the centre of the pulse may be selected by varying the setting of attenuator 44, or altering the rate of one integrator.

Filed: 1972-04-28
Abstract: 1397334 Automatic control of vibration TIME DATA CORP 28 April 1972 [22 July 1971] 19948/72 Heading G3R A vibrating platform or means for producing a vibrating environment (e.g. using sound), for testing equipment, is driven by a random signal controlled by the system shown so that a specimen is subjected to vibration having a predetermined frequency spectrum. Vibration is detected by a device 101, e.g. an accelerometer, having a transfer function h(t); its output y(t) also has a noise factor h(t) and the specification explains mathematically how this is elimated by obtaining the "cross spectral density" from the Fourier transform of the input x(k) to the vibrator as well as its output y(k) and comparing this with the desired (reference) spectrum R(K) at 106. The result is multiplied with a random signal from a generator 109 and the product, after conversion by an inverse Fourier transform device III is used to drive the vibrator. The analogue measurement and drive signals are converted into digital form for processing, e.g. by a general purpose computer. Processing is not continuous but occurs in batches, termed "frames" Fig.5 (not shown). If the inherent delays in the system exceed the duration of a frame, the same input is repeated for one or more frames Fig.6, (not shown). A system which does not eliminate noise in the signals is also described but not claimed Figs. 1... 4 (not shown).
