Title: Improvements relating to the catalytic cracking of hydrocarbon oils
IPC: C10G11/00
Filed: 1940-02-06
Abstract: 538,414. Cracking oils. ARNOLD, C. (Standard-I. G. Co.). Feb. 6, 1940, No. 2265. [Classes 1 (i) and 32] In the catalytic cracking of hydrocarbon oils in the vapour phase in two stages with concurrent passage of the vapour and catalyst through the stages the vapours are contacted in the first stage with a small proportion of the catalyst for a short time in which only a small amount of cracking is effected and are then in the second stage contacted with a large amount of the catalyst for a relatively longer time to complete the cracking reaction. In the first stage the catalyst is preferably whirled into pulverized form by the vapours in a zone of small crosssection while in the second stage the catalyst is mechanically mixed with vapours in a zone of larger cross-section. Suitable catalysts are natural or synthetic silicates, e.g. those of aluminium or magnesium, and active earths containing aluminium or magnesium with which may be incorporated oxides or sulphides of heavy metals, e.g. iron, manganese, chromium, molybdenum. Heated pulverized catalyst is supplied from container A to the first reaction chamber B of narrow cross-section where it is whirled up by vapours fed through line D and mixed with gases produced in the reaction. The vapours then pass to second chamber C of greater cross-section through which the collected catalyst is passed slowly by worm E. Five litres per hour of bleaching earth heated to 455‹ C. are fed per hour from container A while 3 litres of gas oil vapours are fed through D at the same temperature. The catalyst remains for about 0.7-1.2 seconds in part B and for 30 minutes in zone C. A yield of 35.6 per cent. by weight of stabilized gasoline is obtained from an East Texas gas oil.

Filed: 1958-01-23
Abstract: 843,563. Code telegraphy. STANDARD TELEPHONES & CABLES Ltd. Jan. 16, 1959 [Jan. 23, 1958], No. 2273/58. Drawings to Specification. Class 40(3). A ciphered start-stop telegraph apparatus of the kind in which a cipher tape or like medium at the receiver is stepped in synchronizm with the cipher tape at the transmitter comprises means for sending a check signal, to which the receiver replies only if the ciphering arrangements at the receiver and the transmitter are in step, and means for restoring the correspondence between the two ciphering arrangements. In a first embodiment a ciphered check signal is sent at the end of each line of text and no further message text is sent until an answer signal is received from the receiver. If the cipher tapes, or other recording media, are in step the receiver sends back an answer signal which allows further transmission of the message to occur. However, if no answer is received at the transmitter, after a certain waiting period the cipher tape is stepped forward by, say, five characters and locked in that position. The transmitter continues to send ciphered check signals at intervals until an answer is received, indicating that the receiver cipher tape has now been brought to correspond to the locked transmitter cipher tape. Known means are provided at the receiver for rejecting spurious signals of sufficient duration to simulate a start signal. An alarm device is provided to warn the operator if no answer is received during the predetermined waiting period. In a second embodiment, instead of sending a ciphered check signal periodically, a manual or automatic means is provided for sending such signals only during a period when the transmitter is not sending information and at intervals dependent upon the time interval during which a given number of false characters is received.

Title: Method of and apparatus for determining the direction of the mutual temporal shift of two similar stochastic signals
IPC: G06F17/15
Filed: 1977-01-21
Abstract: The stochastic signals A = A(t) and B = B(t) arise, for example, from two signal sensors guided one behind the other over a rough surface at a time interval T. The clock-pulse generator (15) forms time intervals  DELTA  t > T. The signal values A(k. DELTA t) and B(k. DELTA t) of each interval start, k = 0,1,2..., are stored in sample-and hold circuits (13, 14) for the interval time  DELTA t. Subtraction circuits (17, 18) then continuously form the differences A(k. DELTA t) - B(t) and B(k. DELTA t) - A(t) from the stored values A(k. DELTA t) and B(k. DELTA t) and the continuously varying instantaneous signal values B(t) and A(t) of the respective other signal. Full-wave rectifiers (19, 20) form the absolute values therefrom and feed an integrator (21) which forms the time integral of the difference between the two absolute-value signals. Depending on the direction of displacement, after a short time the output value of the integrator (21) exceeds a positive or negative threshold value (23, 26), from which it is possible to read off the direction of displacement, and this is so without the need for a speed measurement. <IMAGE>
