Title: Improvements in apparatus for cooling or attemperating oil or other liquid
IPC: F28F27/00
Filed: 1935-08-13
Abstract: 460,047. Radiators for aircraft and motor vehicles. BROWN, C. A. Aug. 13, 1935, No. 22811. [Class 29] An oil &c. cooler comprises honeycomb type cooling units connected in series and having at least two byepass valves, controlled automatically either by pressure or temperature or both, and so that the valve associated with the unit through which the oil enters the cooler is the first to open. An air-cooled oil cooler comprises units 1, 2 through which the oil and air pass in counterflow, and which are provided with spring-loaded byepass valves 26, 30, the valve 26 through which the oil enters the unit being loaded to open at a pressure higher than the valve 30. The oil enters the duct 8 of the unit 1 and passes through the port 9 and the sections of the unit to the duct 20 which is connected to the next unit. In a modification, the byepassed oil flows through annular passages around the cooling sections of the units. Fig. 6 shows another arrangement comprising three units secured together by bolts 58 and each provided with a casting having an oil inlet 61, Fig. 8, communicating directly with the unit through a port 62, a byepass valve chamber 63 connected inside the unit with the port 62 and directly with an outlet 68 connected to the next unit. The cooled oil from the first unit passes through a port 71 to the outlet 68. The byepass valves of the units are set to open at successively higher pressures from left to right. In cooling liquids such as water, the valves are controlled thermostatically and may operate shutters controlling the air flow through the cooler. Further, the spring-loading of the valves may be varied thermostatically. Specifications 166,930, 219,788, [both in Class 64 (iii)], and 232,309, [Class 29], are referred-to.

Abstract: 172,358. Hinchley, J. W. Aug. 3, 1920. Travelling-band presses. - Apparatus for expressing liquid from material such as peat, of the type in which a succession of measured quantities of the material are pressed between an upper and a lower conveyer, has the conveyers arranged to run at different speeds, so that the material is compressed in a longitudinal direction by engaged parts of the conveyers. The links of the lower conveyer are formed of receptacles each having a perforated bottom 3, Fig. 2, a front wall 17 and perforated side-walls 18. The upper conveyer consists of plates 51, Fig. 1, with projections 5 which enter the receptacles of the lower conveyer. The receptacles are filled with peat from a hopper 8 which may be fitted with an agitator 20 and with plates 22, 23 which prevent overflow of the filled receptacles. The pitch of the projections 5 and the speed of the upper conveyer are proportionally greater than the pitch of the receptacles and the speed of the lower conveyer, so that during its period of engagement a projection compresses the peat in the receptacle below against the front wall of the latter. Guide-rails 14, 15 are provided for the link rollers. The apparatus may be used for the treatment of peat of high water content prior to treatment in the press described in Specification 3998/15.

Title: Process of thermally cracking hydrocarbons with rapid decoking  cycling
IPC: C10G9/16
Filed: 1970-05-12
Abstract: 1306962 Decoking cracking tubes ESSO RESEARCH & ENG CO 12 May 1970 [28 July 1969] 22899/70 Heading C5E In a process for steam-cracking hydrocarbons, e.g. to produce ethylene, propylene and butadiene, by passage through one or more tubes arranged in a cracking furnace, the problem of coke deposition is alleviated by periodically taking at least one tube off stream prior to the time at which the temperature drop across its coke deposit exceeds 50‹ F., passing a decoking feed through said tube for up to 12 minutes, and then returning said tube to on-stream operation. Suitably cyclic decoking is operated. Suitable decoking feeds include steam/hydrogen, steam/  oxygen and steam/sulphur-free C 2-6  paraffin, especially ethane. The effluent from the tube(s) being decoked is desirably mixed with the effluent from the on-stream tubes, and is of such temperature that additional cracking may take place within the effluent, particularly if oxygen is present. The process is particularly suited to the cracking of heavy feeds, e.g. vacuum gas oils, crudes and reduced crudes, though other feeds are mentioned. In the examples, a furnace having 12 tubes is cyclically decoked, the onstream time of each tube being 5¢ minutes and the off-stream time ¢ minute.

IPC: G11C7/02
Filed: 1959-07-03
Abstract: 862,855. Circuits employing bi-stable magnetic elements. STANDARD TELEPHONES & CABLES Ltd. July 3, 1959, No. 22927/59. Addition to 847,334. Class 40 (9). [Also in Group XL (c)] In a coder as described in Specification 849,894 in which the amplitude of a signal selectively determines the generation of pulses in output windings each time a triggering pulse is applied, a similar pair of saturable cores 1, 2 ; 3, 4; 5, 6, Fig. 1, is allotted to each amplitude step as described in the parent Specification, and output windings 10 for each digit are provided on each and every core, those output windings in which flux reversal of a core requires a digit pulse to be generated being wound in one direction relative to the trigger windings 7, while those windings in which an output pulse is not required are wound in the opposite direction. This arrangement of output windings is stated to provide a substantial reduction in the spurious outputs generated by the triggering pulse, the spurious outputs being due to non-rectangularity of the hysteresis loops of those cores responsive to other signal amplitudes. In the circuit shown in Fig. 1, only one set of output windings 10 and a single digit conductor 13 is shown; for a seven-digit code the output windings and digit conductors would be arranged as shown in Fig. 2. Each digit conductor circuit includes a rectifier 14 for suppressing spurious pulses of opposite polarity to a digit pulse, and an amplifier 15 which is gated by a gate pulse generator 21. The amplifier is only unblocked during the periods when output digit pulses are due, the generation of these pulses being determined by a sine wave source 17 and a trigger core 19 as described in the prior Specifications. Specification 849,891 also is referred to.
Patent GB-833680-A (GB)
Title: Production of aromatically substituted carbinols
Filed: 1956-07-25
Abstract: An aromatically substituted carbinol of the general formula Ar(R)2C.OH, in which Ar is an aromatic hydrocarbon radical and R is an alkyl radical, is produced by decomposing the corresponding hydroperoxide or its alkali or alkaline earth metal salt in an alkaline medium at an elevated temperature.  The preferred temperature for carrying out the process is between 50 DEG  and 150 DEG  C.  It is advantageous to effect the decomposition in the presence of the corresponding hydrocarbon since part of the hydrocarbon is then turned into the carbinol during the process. A solution of the hydroperoxide in the corresponding hydrocarbon, obtained by partial oxidation of the hydrocarbon, or the pure hydroperoxide may be flowed into a heated solution or emulsion of hydrocarbon and aqueous alkali.  When an alkali or alkaline earth metal salt of a hydroperoxide is decomposed, the alkaline medium is provided instantaneously by decomposition products.  In the examples cumyl hydroperoxide and sodium cumyl hydroperoxide are decomposed to give dimethylphenyl carbinol with small amounts of acetophenone and benzoic acid; and p-cymylhydroperoxide is decomposed to give dimethyl-p-tolyl carbinol with some p-methyl acetophenone and p-toluic acid.  The cumyl hydroperoxide used as starting material may be made by mixing cumene with oxygen and heating the mixture in the presence of copper phthalocyamine.
