Patent GB-496273-A (GB)
Title: Process for the production of paraffin hydrocarbons
IPC: C07C2/62
Filed: 1937-05-25
Abstract: Liquid paraffins of high anti-knock value are produced by alkylation of isobutane with a normally gaseous olefine of more than 2 carbon atoms in the presence of aluminium chloride and hydrogen chloride at temperatures of about -50 to 0 DEG  C., a molecular excess of the isobutane being maintained during the reaction.  Mixtures of the olefines with one another or with inert gases, e.g. petroleum cracking gases, may be used.  Olefines free from paraffins may be obtained by extraction with selective solvents among which are liquid olefines, especially polymers. Isobutane may be cooled to -10 DEG  C. in the presence of aluminium chloride, usually about 5-20 per cent by weight of the reacting hydrocarbons, and isobutene and hydrogen chloride gradually introduced.  Alternatively, the solid catalyst suspended in liquid isobutane may be passed continuously through a tubular reactor after addition of isobutene and HCl.  The molar ratio of isobutane to olefine is preferably about 3 to 1.  In the case of propene, reaction is accelerated by continuous addition of small amounts of butenes, say about 5 per cent of the propene, or prior treatment of the aluminium chloride with butenes.  This prior treatment of the catalyst also prevents its dispersion into very fine particles.  Generally the reaction temperatures are -50 to -30 DEG C. for isobutene, -30 to -10 DEG  for n-butenes, and -10 to 0 DEG for propene or, if activated with butenes, -20 to 0 DEG  C.  When using mixtures of olefines, each may be reacted in one of a succession of stages.  In examples: (1) isobutene and HCl are passed into a suspension of aluminium chloride in isobutane at -35 DEG  C.; (2) a liquefied mixture of isobutane and n-butenes is contacted with aluminium chloride, HCl being continuously added.  The ratio of the reacting hydrocarbons and contact time is varied; (3) the solid catalyst is activated by adding isobutane and isobutene at -10 DEG C.  Liquid isobutane and propene are fed below the surface, reaction products being siphoned off.  These contain isoheptanes and isodecanes.

Abstract: 475,585. Coating valves and valve seats with metals; alloys. WILCOXRICH CORPORATION. May 25, 1936, No. 14754. Convention date, June 3, 1935. [Classes 82 (i) and 82 (ii)] [Also in Groups XXII and XXVII] Valves and valve seats, particularly for internal-combustion engines, are coated on their co-operating faces with an alloy which will resist oxidizing, burning and pitting at high temperatures. The coating is applied, after the part has been cleaned and preferably preheated for example in a molten flux bath of borax or cryolite, by immersing the portion to be coated in a bath of the molten alloy and rotating the part. To increase the thickness of the coating adjacent the line of contact between the valve and the valve seat projections or grooves may be formed on or in the part, as shown at a in Figs. 4 and 7, for a valve and in Fig. 10 for a valve seat ring. The coated portion is afterwards worked to form a face which may be flat or sloping at any desired angle, various forms of faces being shown in the drawings. The thickness of the coating applied may be varied by varying the speed of rotation or the temperature of the bath ; a thick coating may be formed by several immersions. A coating of another metal such as aluminium, bronze, brass, or copper may be first applied by spraying, dipping, plating &c. to provide a clean surface to which the coating alloy will bond. The coating alloy may be that known under the Registered Trade Mark " Stellite " and the composition of other alloys which may be used is specified, one group of these alloys containing iron, carbon, silicon, chromium, and manganese and one or more of the elements molybdenum, tungsten, boron, nickel, and cobalt; and the other group being aluminium bronzes containing copper, aluminium and iron, and either manganese, or nickel, or chromium and cobalt.

The auxiliary tank c, Fig. 2, is fed by gravity from the main tank through a pipe d and non-return valve l and is connected to the feed tank by a pipe e. l'ressure fluid is admitted at f. A piece of bent pipe h has secured thereto a pin i which is mounted in the tank and supported by a bracket e'‹. An arm j is pivoted on the pin i, is actuated by a float k and carries stops j<2>, j<3> adapted to engage the pipe h so as to bring the coned end h<1> thereof into or out of engagement with the screwed socket e' into which the pipe e is fitted. Whilst the tank is empty or partly full, the end h<1> is withdrawn from e<1> and the pressure fluid entering at f escapes through the pipe e and ultimately to atmosphere. When the tank is full, the pipe h becomes part of the pipe e and the pressure of the air or gas forces the liquid through pipes h, e to the feed tank. In a modification, the bent pipe is replaced by a float-actuated valve in the top of the tank and the outlet e is in the bottom of the tank. The auxiliary tank exposes a comparatively small surface to bullets when the apparatus is used on an aeroplane.

Abstract: 370,709. Wireless signalling. SOULLIE, C., 10, Boulevard Malesherbes, Paris. May 21, 1931,.No. 15056. Convention date, July 30, 1930. [Class 40 (v).] For the elimination of the effects of fading and like disturbances on radiotelegraphic messages, the message is repeated a plurality of times and elements missing from the first record or registered from the first transmission are added to the record or registering device by subsequent transmissions In apparatus using a perforated strip record, the same place on the receiving strip may be under the same or corresponding perforating punches at the moment when the repeated elements of the same letter are being received so that elements missing in one received version are restored in later versions. This principle can be extended to multiplex apparatus. In apparatus employing slow-acting relays, it is arranged that the release of any electromagnet automatically transfers its effect to the final receiver as follows. In a Baudot type of receiver the sectors SR1, SR2, SR3 shown developed in the Figure comprise a divided ring C1 coupled to the continuous ring C2 by the brush B and C3 coupled to C4 by brush B1. The contacts of C1 in sector SR1 are connected to five slowacting relays a . . e provided for closing contacts al .. e1 of the sector SR2 after the time interval between successive transmissions of the same letter. Similarly relays f .. j control contacts /1 .. j1 of sector SR3 with the same time lag. The translating electromagnets 1 .. 5, are connected to C1 in sector SR3. With this arrangement, if the letter sent is represented as at K, and as received at L, M, and N, the first series of elements received will energize relays a, d, and e. The second will operate g and i but f and j will also be operated by the contacts al and e1 connected to relays a and e. The third series will operate translators 2, 3, and 4 but 1 and 5 will also be operated by contacts f1, j1 connected to magnets f and j. The magnets are operated by the battery P either through the receiving relay R or the contacts al .. j1 which may have been closed by a previous signal.
