Patent GB-964126-A (GB)
Title: Process for preparing polyaromatic petroleum resin emulsions
IPC: C08J3/03
Filed: 1962-06-15
Abstract: An emulsion of a polyaromatic resin and a plasticizer therefor in water is made by completely fusing together the resin and the plasticizer, incorporating an anionic emulsifier into the plasticized resin in the fused condition and incorporating water into the mixture of emulsifier and plasticized resin until an emulsion of the plasticized resin in water is formed. Polyaromatic resins are the thermoplastic resins obtained by the distillation of tars resulting from the steam-cracking of petroleum fractions.  The emulsifier may be added by mixing with the resin in the fused condition an organic acid which on saponification yields an anionic emulsifier and then incorporating into this mixture an aqueous alkali to saponify the acid.  Specified plasticizers are mineral oils, oily polymers or copolymers of olefins or conjugated diolefins; polymers lighter than the resin itself but derived from the same tars or paraffin or crude or refined petroleum waxes.

Filed: 1973-05-17
Abstract: 1432171 Valves W JONES 15 May 1974 [17 May 1973] 23546/73 Heading F2V [Also in Divisions A5-A6] An inflation valve comprises an inlet 42; an inlet valve member 49 having an input face, part of which is engageable with a seal 47; a restricted passageway between the disc-shaped member 49 and the cylindrical wall 51 from a first space 53 on the input face side of the inlet valve member 49 to a second space 54 on an output face side of the inlet valve member 49; an outlet valve member 62 having a first face 63 engageable with a seat 64 and capable of being exposed directly or indirectly to pressure in said second space 54 (as shown) or said first space 53, and a second face 65 exposed to exhaust pressure; a rod 51a between coaxial members 49, 62 and the rleative areas of the faces ensuring that a pressure differential above a given value between the first space 53 and the second space 54 causes the inlet valve to be held open and the outlet valve to be held closed, but when said differential falls below said value the inlet valve is closed and the outlet valve opened. As shown, anaesthetic gas is fed to inlet 42 and a reservoir bag fitted to passage 43. When the valve is used for totally controlled breathing, at a gas pressure in the reservoir preset by control 79 which preloads spring 68, the inlet valve member 49 lifts off seat 47 and pressure acts on the whole underside of member 49 fully opening the inlet valve and closing the outlet valve member 62 on to seat 64. Gas flow from space 53 through the restricted passageway between the discshaped member 49 and the cylindrical wall 51 into space 54 and via flap-valve 85, output member 45 and a flexible tube to the patients' mask. Gas flow to the mask lessens the pressure in the reservoir, spring 68 closes the inlet valve and opens outlet valve to allow flow from the mask through a flexible tube, an inlet 59, a flap-valve 87 and the outlet valve to exhaust space 56. When the reservoir pressure has again built up, the cycle repeats. Communication between second space 54 and seat-engageable face 63 is via the tubes and mask, i.e. indirect and face 63 is exposed to the pressure at the patient outlet. In the embodiment of Fig. 1 (not shown) there is direct communication between second space (34) and seat-engageable face of outlet valve member (12) and the face is exposed to the pressure at patient outlet (39). In the embodiment of Fig. 3 (not shown) seatengageable face of outlet valve member (97) is exposed to the pressure of gas inlet (90) and communicates directly with first space (91).

Abstract: 1,129,532. Indicating and inspecting. L. GIBBS. 31 May, 1966 [3 June, 1965], No. 23696/65. Heading B7H. [Also in Divisions F1, G1 and H3] When a motor vehicle is running out of petrol, the frequency of operation of the petrol pump increases, and this increase in frequency is detected electrically to operate a warning. In the arrangement shown in Fig. 2 the electrical supply to the pump passes through the primary winding 9 of a transformer, the secondary winding of which is connected through a rectifier 3 to a capacitor 4 shunted by a bleed resistance 5 and a neon lamp 6. At low frequencies the potential across the capacitor is small, but at higher frequencies the potential rises sufficiently to fire the neon lamp 6 which provides the warning. With the circuit shown the lamp 6 will flash when the input frequency is too high; a, resistance may be inserted in series with the lamp so that it remains on instead of flashing.

Patent GB-878035-A (GB)
Title: Improvements in or relating to the catalytic isomerization of olefinic hydrocarbons
IPC: C07C2/00
Filed: 1960-07-11
Abstract: Unbranched or sparsely branched olefins are converted into branched or more highly branched hydrocarbons by contact, at elevated temperature and pressure in the presence of hydrogen, with a solid, acidic, isomerisation catalyst on which is supported one or more sulphides, selenides, tellurides, antimonides and/or arsenides of a Group VIa and/or VIII metal.  The olefin preferably contains 3-8 carbon atoms and may be mixed with other hydrocarbons, alkynes and dienes present, being selectively hydrogenated; the product may contain branched hydrocarbons containing more or less carbon atoms per molecule and is partially or completely hydrogenated.  A suitable starting material for producing a gasoline product is a catalytically cracked fraction having an end point of 80-130 DEG C.  The catalyst base (acidic to butter yellow indicator) may be silica-alumina, silica-zirconia, boria-alumina, boria-silica or alumina-halogen and may contain 0.5-15% by weight of the total catalyst of the metal compound which is preferably nickel and/or cobalt sulphide. The reaction is effected, preferably in the vapour phase, at 100-500 DEG C. and 10-100 atmospheres and a hydrogen partial pressure at least 5% of the total using one or a plurality of reactors using an L.H.S.V. of 0.5-20 vol./hr./vol.  The feed is preferably preheated by recycling a portion of the product in an amount 0.005 to 0.1 times the difference between the bromine numbers of the feed and product, such recycle being heated to 10-100 DEG C. higher than the temperature at the beginning of the reaction zone; this prevents fouling of the heater e.g. pipe still, and also prevents excessive temperature rises in the reactor.  Alternatively the feed is heated by indirect heat exchange with product from the first or final reactor such product being heated to 10-50 DEG C. above the temperature at the beginning of the reaction zone.  If desired, the product, if not completely hydrogenated in the process, may be catalytically hydrogenated conventionally over nickel, platinum, cobalt and molybdenum sulphides or cobalt and molybdenum oxides.
