Patent GB-761862-A (GB)
Title: Improvements relating to the treatment of petroleum distillates to reduce their corrosivity
IPC: C10L1/182
Filed: 1953-04-15
Abstract: The corrosivity of a petroleum distillate, which has been subjected to desulphurization by contact in the presence of hydrogen with a sulphur-resistant hydrogenation catalyst at elevated temperature and pressure followed by redistillation, is reduced by intimately mixing the distillate with a minor proportion of a polyhydric alcohol and separating the distillate from the alcohol.  After this treatment, the distillate passes the B.S.I. copper strip corrosion test.  The treatment is particularly applicable to solvent naphthas for use in the dry cleaning and paint industries.  Suitable polyhydric alcohols are glycerol and ethylene glycol.  In an example, a Kuwait naphtha of 153.5-212 DEG C. boiling range is subjected to hydrocatalytic desulphurization at 780 DEG F. and 100 p.s.i.g., using a catalyst consisting of the oxides of cobalt and molybdenum or alumina, and then redistilled.  It is then washed with caustic soda solution, agitated with glycerol and separated from the glycerol.

Title: Electronic sphygmomanometer and oscillometer
IPC: A61B5/022
Filed: 1946-04-03
Abstract: 636,458. Sphygmomanometers. LORIA, W. J., and SUHRE, J. April 3, 1946, No. 10306. Convention date, April 7, 1945. [Class 81(ii)] [Also in Group XL(b)] A blood pressure measuring device comprises a light sensitive means 34 actuated and varied by an applied pressure and energizing an indicating means 14 in proportion thereto, a second light sensitive means 27 actuated by the varying pressure of blood flowing in an artery as the said applied pressure is reduced from a supersystolic pressure to a lower value, and a second indicating device 16 energized by said means 27 to indicate only said variations in blood pressure. In operation, the pressure applied to the limb under examination is transmitted through a tube 44 to two branches thereof; branch 46 communicating with an aneroid capsule 40, whilst branch 50 communicates with aneroid capsule 42. A vane 48 is actuated by said pressure in the capsule 40 and is deflected accordingly whilst a vane 52 is similarly affected by the capsule 42. Interposed between the vanes is a stationary opaque curtain 58 having an opening 60 so arranged that an opening 64 (see Fig. 3) in a shield 62 on the vane 52 will always lie inside the shield 62 otherwise completely covering the opening 60 so that a constant quantity of light passes from a lamp 24 to the photo-electric tube 27, except when a shield 65 on the vane 48 partly obscures it. When the applied pressure is super-systolic, the quantity of light passing is constant, but when the pressure is reduced the blood will begin to flow and the amplitude of pulse beat will affect the vane 48 (but not the vane 52 as this is damped down) and the shield 65 will partly obscure the lamp 24. The current generated by the tube 27 is amplified and indicated on the device or meter 16, the applied pressure being simultaneously shown on the device or meter 14 by means of a further shield 66 on the vane 52 which intercepts light from a bulb 30 to the tube 34. The finer small change on the -meter 16 is the systolic pressure, and the maximum reading obtained on reducing the applied pressure is the diastolic pressure. To obtain the pulse rate, a relay is incorporated in the circuit of the meter 16 and its operating coil is actuated in synchronism with the energy supplied to the meter 16 To use the device as an oscillometer, the applied pressure on one limb is noted, then that on another limb, and the results examined.
