Title: Manufacture of an organic dinitrile
Filed: 1948-02-11
Abstract: A process for the manufacture of 1 : 4-dicyano-2-butene comprises reacting a 3 : 4-dihalo-1-butene or a mixture thereof with an isomeric 1 : 4-dihalo-2-butene, wherein the halogen atoms are of atomic weight between 35 and 80, with hydrogen cyanide under non-alkaline conditions.  Mixtures of 3 : 4 and 1 : 4-dihalobutenes, obtained in the halogenation, for example chlorination of 1 : 3-butadiene, may be used.  The hydrogen halide formed in the reaction may be neutralized with reactants which do not introduce alkalinity such as the carbonates of magnesium, calcium zinc or barium, or in substantial absence of water, of an alkali cyanide.  In the absence of neutralizing agents lower yields are obtained.  As a diluent excess of hydrogen cyanide may be used or dioxane, benzene, toluene, diethyl ether, acetonitrile, propionitrile, methanol, ethanol or 2-methoxymethanol and similar essentially neutral liquids.  Cuprous halides and copper catalyse the reaction and act as stabilizers for hydrogen cyanide in the presence, e.g. of stainless steel.  In the presence of sufficient diluent other than hydrogen cyanide the reaction may be conducted at atmospheric pressure, otherwise the use of closed vessels is advisable.  In examples, 1 : 4-dicyano-2-butene is obtained when (1) 3 : 4-dichloro-1-butene and hydrogen cyanide are heated in the presence of calcium carbonate and cuprous bromide; (2), (1) is repeated using equal parts of 3 : 4-dichloro-1-butene and 1 : 4-dichloro-2-butene; (3), (1) is repeated using a crude product of chlorination of 1 : 3-butadiene; (4) 3 : 4-dichloro-1-butene is heated with hydrogen cyanide in the presence of calcium carbonate or a mixture of equal parts of the 3 : 4-dichloro-1-butene and 1 : 4-dichloro-2-butene is similarly treated; (5) 3 : 4-dichloro-1-butene and hydrogen cyanide are heated in the presence of cuprous bromide, sodium cyanide and methyl alcohol. Specifications 646,964 and 646,966 are referred to.

Title: Improvements in or relating to methods of, and apparatus suitable for use in, attaching heels to shoes
IPC: B29C45/07
Filed: 1948-02-13
Abstract: 637,053. Heel-attaching. BRITISH UNITED SHOE MACHINERY CO., Ltd. (United Shoe Machinery Corporation). Feb. 13, 1948, No. 4210. [Classes 17 (i) and 17 (ii)] [Also in Group XXVIII] A heel is attached by forcing plastic material in suitable condition into recesses in the heel and heel seat, while the heel and shoe upper are held pressed together, and allowing it to harden. An example of suitable shoe construction is shown in Fig. 3. A sole 82 with a tab 84 terminates at the heel breast line while a shank piece 86 extends under the lasted upper margin. A tuck piece 104 cut with tabs 106 is inserted between the insole and the lasted upper 88 and counter 89 and is held by the lasting tacks 87. A heel 92 with a recess 94 in its seat has a bore 96 extending to the tread surface and, when clamped in position on the shoe upper and insole, forms a seal with the heel seat. Plastic material forced into the hole 96 fills all voids in the heel seat area, and spaces, 107 formed in the tuck 104 allows it to spread beneath the overlasted upper margins. The shank piece 86 is firmly held and a firm base formed beneath the insole. Several modifications of the recesses in the heel and heel seat are described and, if desired, a piece of plastic sheet preferably perforated may be lasted to lie beneath the insole so as to fuse with the injected heated plastic. An apparatus for injecting the plastic comprises a clamp 12, Fig. 1, having a hole 16 to allow access to the bore 96 of the heel by an injecting nozzle 36. A cyclinder 22 with end plates 24, 26 is slidably mounted on angle plates 20. A pipe extension 30 extending from the plate 26 forms a chamber 40 leading to a heater 32 from which the nozzle projects. A heater 38 is manually adjustable over the nozzle so that the plastic is kept fluid in the whole system. A hook 54 allows partial withdrawal of a piston rod 50 to permit charging the tube 30 through an orifice 42. In operation, pressure fluid is admitted by a pipe 66 from a control valve 56 to one side of a piston 52 so that the piston rod 50 forces the plastic material through the nozzle until a predetermined pressure is built up between the heel and heel seat until the force exerted by a weight 80, tending to pull the cylinder 22 towards the clamp 12 is exceeded at which point the nozzle is pushed away from the recess. The valve 56 is then operated to admit fluid through a pipe 64 to cause the piston to be retracted.

Abstract: 1342438 Wave-energy exploration of a medium SOC NATIONALE DES PETROLES D'AQUITAINE 28 Jan 1972 [2 Feb 1971] 4215/72 Heading H4D In a system for exploring a medium by emitting waves into it from at least two sources at different instants and receiving waves reflected from within the medium, the time interval separating two consecutive wave emissions respectively produced by different ones of the sources is less than the longest go-and-return wave travel time T of interest, the time interval separating two consecutive emissions from any one source is at least equal to the longest go- and-return time T, and the emission instants are such that cross-correlation, over time T, of the sequence of emission instants of at least one source with the combined sequence of emission instants of all the sources gives a correlation function in which the ratio of the amplitude of the maximum peak to the amplitude of each secondary peak is greater than the ratio of the amplitudes of received signal samples separated by time intervals corresponding to the time intervals separating the maximum peak from the secondary peaks. These conditions enable the use of several sources concurrently for economy of exploration time, without the need to synchronize the sources. In the embodiment described, for land or marine seismic exploration, two or three pulsesources and one or two lines of seismometers are used in a roll-along survey method. The source emission sequences and received signals are separately recorded. To identify the received signal components associated with any one emission source, the recorded emission sequence of that source is cross-correlated with the received signal record; the same is done for each of the other sources.
