Title: Process for the production of reactive acid liquor, alcohols, esters and the like from olefine hydrocarbons
IPC: C07C29/06
Filed: 1919-04-22
Abstract: Petroleum products containing olefine hydrocarbons, particularly the distillates obtained from cracking processes such as the Burton process, are treated with sulphuric acid of 1.57-1.84 specific gravity at a temperature below 30 DEG  C. and preferably at 10-20 DEG C. to obtain an acid liquor containing alkyl sulphates.  The acid may be added gradually or may be sprayed into the oil.  The oil may be treated with successive batches of acid or an apparatus in which the acid and oil flow in countercurrent may be used.  The mixture may be cooled.  The acid liquor is separated by settling or centrifuging, and when mixed with water or other hydrolyzing-agent and distilled yields monohydric alcohols chiefly secondary alcohols.  The oily liquid that separates on admixture of the acid liquor with water, and which consists mainly of olefines, may be dissolved in sulphuric acid. The alcohols may be purified by olefines by solution in water or in sulphuric acid of 1.57 specific gravity.  The acid liquor may be treated with organic acids or salts such as calcium acetate, and the mixture distilled to obtain esters.  Gasolines which contain diolefines and like unsaturated hydracarbons are subjected to a preliminary treatment with concentreated sulphuric acid, the temperature being allowed to rise, and the acid tar or sludge formed by the treatment being removed.

Title: Scanning and recording means
IPC: A61B6/00
Filed: 1966-03-08
Abstract: 1,145,088. Radio-active material concentration monitoring. H. LEITER. 8 March, 1966 [6 April, 1965], No. 10126/66. Heading H4F. In an apparatus for detecting and storing signals generated by radio-active material statically disposed within a predetermined area, such as in a human body into which an isotope has been introduced to locate a malignant growth, a detector is scanned in a predetermined pattern across the area to generate sequential signals in accordance with the concentration of radio-active material at sequentially scanned points, the signals are recoverably stored or recorded, and transmission means operated by the scanning mechanism at predetermined times during the scanning pattern connect a source of control signals to a second store or record. In the arrangement described, a scintillation detector is reciprocated by a motor-driven chain arrangement up and down adjacent parallel lines across the body and its shaped and processed output is recorded on one track of a magnetic tape, tone control signals being applied to a second track at the beginning and end of scanning and at each reversal of the head. The signal processing depends on the nature of the desired display. A photograph of a similarly moved light source modulated in intensity by the signals may be simultaneously or subsequently produced, or a cathode-ray tube may be controlled by the signal and photographed, and variable exposure control may be provided to produce satisfactory pictures. The signal amplifying arrangements may include threshold, limiting and pulse shaping features. Detector and lamp carriage drive and reversing arrangements are described in detail.

Title: Improvements relating to thermionic valve control circuits
IPC: H03K17/54
Filed: 1946-07-09
Abstract: 630,123. Valve circuits. SCOLES, G. J. and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. July 9, 1946, No. 10214/49. Divided out of 630,075. [Class 40 (vi)] In a gating circuit of the kind comprising a gating and a control valve which are cathode coupled together the gating valve being rendered operative and inoperative by signals applied to the grid of the control valve both valves have anode load resistors and their anodes are connected together by a further resistor so as to maintain the mean anode potential of the gating valve constant. The Figure shows a control valve V1 and a gating valve V2 coupled by cathode resistor R1 so that V1 is normally conducting and V2 cut-off. When a control signal is applied to terminal G valve V1 is cut-off, V2 conducts and signals at terminal I appear at the output O. The drop in the mean potential of the anode of V2 when it becomes conducting is prevented by feeding a voltage from the anode of V1 via resistor R4. The values of resistors R3 and R4 are adjusted to maintain the mean anode potential of V2 constant. Specification 621,752, [Group XL (b)], is referred to.

Title: Brake having deflection compensating means therein
IPC: F16D65/54
Filed: 1956-04-04
Abstract: 795,041. Automatic brake-adjusting mechanism. GOODYEAR TIRE & RUBBER CO. April 4, 1956 [Sept. 2, 1955], No. 10261/56. Class 103 (1). In a brake having an hydraulically actuated piston and cylinder mechanism 6, 5 respectively, an adjusting pin 14 extends into hollow piston 6 through a friction disc 15 and is formed with a head 16 which abuts a U-shaped sectioned sealing ring 18, situated between the head 16 and the closed end of hollow piston 6, working in conjunction with a sleeve 21 and a spring 23 to compensate for brake-lining wear and to ensure complete brake release when the fluid pressure is released. Fig. 3 illustrates the condition when the fluid pressure to the piston and cylinder mechanism has just been released wherein the U-shaped sealing ring 18 is expanded by hydraulic fluid trapped between the head 16 of the adjusting pin and the closed end 7 of the piston to make the adjusting pin 14, head 16 and piston 6 a unit insofar as external return forces applied to the piston are concerned so that any deflection of the housing or friction surfaces is transmitted to the adjusting pin for moving it axially in the friction means 15. The pressure set up on the head 16 by the entrapped hydraulic fluid will slowly be relieved by passage of hydraulic fluid through bleed hole 17 in head 16 so that ultimately the piston 6 will be free for movement independently of the adjusting pin 14 and the spring 23 will return piston 6 to the normally spaced inoperative position of sleeve 21 in relation to head 16 of the adjusting pin, as indicated in Fig. 1.

Filed: 1955-04-07
Abstract: 768,504. Sorting letters. POSTMASTER GENERAL. April 7, 1955, No. 10364/55. Class 78 (1). Postal letters and like flat articles are fed singly to a position in front of a sorter by a pair of oppositely rotatable single-turn helices 12 and a smaller pair of helices 17. The letters are fed to the helices by a horizontal belt conveyer 21, preferably comprising three narrow spaced belts, inclined similarly constructed belt conveyers 22, 23, 24 driven at progressively increasing speeds, a suction head 25, opposed pairs of endless tapes 27 and a plate 15. Rollers 20 in the same plane as the shafts of the helices 17 are driven continuously to urge the letters towards a central position. The height of the stack of letters on the conveyer 24 is maintained between upper and lower limits, between which limits the suction head 25 removes the top letter from the stack. The limits are maintained by a pivoted feeler 30 which is moved by a rotary cam 35. When the feeler is in the lowest position, it closes contacts 33 in the circuit of the motor 34 which drives the conveyers. This circuit is closed for a time sufficient for the height of the stack to rise to the upper limit.

Title: Improvements in or relating to the investigation of transfer characteristics
Inventor: BIRT DAVID ROBIN
IPC: H01J49/48
Filed: 1968-03-04
Abstract: 1,237,123. Measuring transfer characteristics; electron fluorescence measurements. VACUUM GENERATORS Ltd. June 3, 1969. [March 4, 1968], No. 10423/68. Headings G1A and G1U. [Also in Division H3] To detect irregularities in the transfer characteristics of a device or system, e.g. a system for Auger electron spectroscopy in which the irregularities correspond to Auger transitions, a signal generator 4, Fig. 3, supplies to the input of the device or system a signal which may be selected to be either (i) at a frequency nf, or (ii) at a frequency# and such as to contain no component at the frequency nf (n being a positive integer greater than 1), whilst a synchronous detector 8 detects that component of the output signal of the device or system at the frequency n#. When the input is at the frequency nf the output of the detector gives a measure of the slope of the transfer characteristic; when the input is at the frequency # the output from the detector gives a measure of the harmonic distortion produced by the device or system. In the system shown for investigating the atomic structure of a specimen 1, the specimen is bombarded with electrons from a gun 2 and the secondary electrons released (including Auger electrons) are collected by a hemispherical collector 3. Interposed between the specimen and the collector is a grid G3 to which is applied the signal from generator 4 superimposed on a D.C. bias from source 5, this bias being swept over the energy range of the released electrons by sweep generator 6. The required frequency component of the collector current is amplified and detected at 7, 8 and applied to an X-Y plotter 9. The signal generator, Fig. 4, comprises an oscillator 10 connected to a frequency dividers 11, 12 which respectively supply squarewave outputs at frequencies 2# and # (n=2), a switch enabling the desired output to be selected. The selected squarewave is integrated at 13 to provide a triangular waveform, which is applied via a tuned transformer matching network 16 to the grid G3. Since the transformer may need to be tuned to either # or 2# its secondary winding comprises two halves which may be connected in series or in parallel, whilst the gain of amplifier 14 is correspondingly switched to maintain a constant signal level. The detector 7, 8 also Fig. 5 (not shown) comprises in series: a transformer matching unit (17); a band-pass amplifier (18); a phase adjuster (19); and the synchronous detector 8, the phase adjuster compensating for any phase shift between the input and reference signals fed to the synchronous detector. An auxiliary asynchronous detector feeding a warning device may be provided to indicate the approach of overload conditions. A further network 50, Fig. 3 may also be provided to neutralize the effects of stray capacitance between the grid G3 and the collector.
