Patent GB-668557-A (GB)
Title: Improvements in or relating to synthesis of oxygenated organic compounds
IPC: C07C45/50
Filed: 1949-04-14
Abstract: Oxygenated organic compounds, especially aldehydes and alcohols are made by reacting olefins, obtained from CO+H2 in the presence of a fluidized synthesis catalyst at about 300 DEG  C., with CO+H2 in the presence of a carbonylation catalyst.  The olefinic synthesis product contains about 80 per cent olefins, even within the C10-C20 range, mainly of straight-chain type, and can be used directly for the reaction to give aldehydes, especially with cobalt catalysts at about 120-200 DEG  C.  In an example, the synthetic olefinic product with a reduced catalyst comprising cobalt, thoria, and magnesia on infusorial earth suspended therein is treated with water gas at 155 DEG  C. and 150 atmos.  After 50 minutes, temperature and pressure are lowered, the product flushed with hydrogen, and hydrogenated at 190 DEG  C., and 150 atmos., to yield alcohols.  Specification 640,115 is referred to.

Title: Improvements relating to photographic cameras
IPC: G03B7/06
Filed: 1956-04-03
Abstract: 796,643. Photographic cameras. DECKEL, H., and DECKEL, F. W. April 3, 1956 [April 7, 1955], No. 10148/56. Class 98(1) '[Also in Group XL(b)] In a camera combined with an exposure meter, either the shutter speed or the diaphragm aperture control means is alternatively couplable either with the other control means or with a follower adjustable in accordance with the indication of the exposure meter. Preferably, only the couplable control means is manually operable, the other being inaccessible. In the form shown, the diaphragm control ring and the shutter speed control ring normally rotate together to effect compensatory changes in the diaphragm aperture and shutter speed so that the exposure remains constant. The diaphragm control ring 20 is provided with a knob 12 on a spring arm extending through an axial slot 10a in a diaphragm scale ring 10 and, for this purpose, teeth 21 on the arm are normally spring pressed by the resilience of the arm into engagement with notches 35 provided on shutter speed scale ring 33. Oppositely directed teeth 21 are engageable with notches 35 provided in ring 31 having gear teeth 32 meshing with teeth 41 of a tube 42 carrying a follower mark 43. In this condition teeth 21 are disengaged from notches 35 and, ring 33 is preferably retained in the position in which it was disengaged by ratchet means, knob 12 being manually held against the spring pressure of its arm and rotated to alter the diaphragm aperture and to bring the follower mark 43 opposite the mark scale 48 indicated by the exposure meter pointer 46. The movement of follower mark 43 is also preferably restrained by ratchet means so that, when disengaged, the mechanism cannot readily be moved out of adjustment. Heavy type numbers as indicated by numbers 8 on scale rings 33 and 10 and a thickened graduation 51 are provided for aligning the mechanism on assembly and for re-aligning it, when !necessary. Exposure meter scale 47 may be linearized and the grid lines 49 omitted. The whole exposure meter 5 may be turned with respect to marks 43 and 58 to adjust the film speed on scale 59 and with respect to mark 43, to bring socket holes 86a into coincidence with holes 86 so that a separate photoelectric cell may be introduced on moving button 88 together with toothed rack 89 which meshes with gear teeth 90. The shutter speed scale ring 33 carries markings for exposure times longer than those for which the shutter can be set and, accordingly, the scale ring 33 has a lost-motion connection with the shutterspeed control ring 30, the letter B on ring 30 appearing in window 53 when the connection is about to be released. Speed control ring 30 is retained in this position by a lock until ring 33 is returned to settable shutter speeds. The camera is provided in the usual way with shutter release button 7 and film wind knob 3 coupled with the shutter setting mechanism. Lens element 9 is movable by screw-thread 27 for focusing. Specification 776,582 is,referred to.

Title: Improvements in and relating to systems for locating objects by sound
IPC: G01S1/72
Filed: 1936-04-08
Abstract: 461,396. Acoustic directional apparatus. BRITISH THOMSON - HOUSTON CO.. Ltd. April 8, 1936, No. 10362. Convention date, April 12, 1935. [Class 118 (ii)] The low-frequency beat of simultaneously transmitted sound waves of differing highfrequencies is used for locating objects, the reflected waves being detected by the binaural method. As shown in the Figure, three sound emitters 1, 2 and 3 arranged to emit notes of different frequencies between 1500 and 5000 cycles per second are energized simultaneously by means of valve 8. The reflected sound waves are received by sound collectors 13, 14 and are fed to stethoscopic ear-pieces 17 through filters 15, which filter-out disturbing noises. The instrument is rotated by handle 12 until the beat frequencies heard by the observer appear to be directly ahead. Frequencies of 2000, 2500 and 3000 cycles per second are suggested giving beat frequencies of 500, 1000 and 1500 cycles per second, but the beat frequencies may be increased by separating the transmitted frequencies by unequal amounts or by increasing the number of the transmitted frequencies. The advantages of the reflection of high-frequency notes and the detection of low-frequency notes are thus combined. Specifications 146,350, [Class 118 (ii)], and 379,429 are referred to.
