Filed: 1963-05-13
Abstract: A process for the production of n-paraffin fractions having a purity of at least 99% by weight comprises treating a petroleum fraction with a 5 <\>rA molecular sieve in known manner to recover an intermediate product containing at least 90%, preferably 95%, by weight of n-paraffins and reprocessing with a 5 <\>rA molecular sieve in known manner to give a fraction containing less than 1%, preferably 0.1%, by weight of isoparaffins and napthenes, wherein either the intermediate product or the low isoparaffin/napthene fraction is de-aromatized, for example by hydrogenation, adsorption in silica gel, alumina or bauxite, or by oleum washing, to obtain the desired n-paraffin product.  Specification 944,441 is referred to.

Filed: 1924-08-13
Abstract: 220,635. British Thomson-Houston Co., Ltd., (Assignees of Jones, B. W.). Aug. 13, 1923, [Convention date]. Electromagnet and thermal switches. - An electromagnetic switch 12, controlling the lamps 9 of an advertising device, is alternately opened and closed by a thermo-electric timnig device 22. The switch 12 comprises a fixed contact 13 and a movable contact 14 carried by an arm 16, to which is pivoted an over-centre device, comprising a spring 17 and pin 18, and the armature 19 of operating coils 20, 21. The drawing shows the apparatus during the cooling of the bimetallic thermal element 23 of the device 22, the element 23 flexing towards a fixed contact 26. When the element 23 engages the contact 26 a circuit is completed from the supply 11 through coil 20 and thence through the parallel circuits of a heater 25 and the lamps 9 to the supply 10. Owing to the resistance of the coil 20 neither the heater 25 nor the lamps 9 become effective, but the switch is thrown to the closed position thereby compiteting a circuit from the supply 11 through contacts 14, 13 and lamps 9 to the supply 10 and a parallel circuit through the, heater 25, aLso a short circuit is established around coil 20 and contact 26 thereby preventing arcing at contact 26 when the element 23 begins to flex towards a contact 27. When the element 23 engages the contact 27 a circuit in parallel with the lamps 9 is established through the coil 19 thereby opening the switch 12 and interrupting all the circuits, whereupon the element 23 again cools. The contacts 26, 27 are adjustable so as to vary the periods during which the lamps 9 are illuminated and extinguished. Switches, operated manually or by a time clock may be placed in the supply leads so as to initiate and terminate the operation of the device. The Specification as open to inspection under Sect. 91 (3) (a) states that the invention is not limited to flashing sign circuits. This subjectmatter does not appear in the Specification as accepted.

Abstract: 302,643. Claude Neon Lights, Inc., (Assignees of Beck, L. L.). Dec. 19, 1927, [Convention date]. Vacuum tubes; low-pressure metallic-vapour apparatus.-A lamp giving light from the positive column contains mercury and a mixture of rare gases such as argon which produces light of a colour similar to that produced by mercury, a heat-producing gas such as helium, and a diluent such as neon. The discharge develops sufficient heat to maintain mercury vapourized and the light remains constant at low external temperatures. For example the discharge in a lamp containing mercury, 30 per cent of neon, and 70 per cent of helium at a pressure of 7.5 millimetres of mercury maintains its blue colour down to 28‹ F. and to-49‹ F. at a pressure of 30 millimetres; argon may be added, for example, in an amount equal to 0.5 or 2 millimetres. The amount of mercury may be three to four grammes per fifteen feet of tubing. Reference has been directed by the Comptroller to Specifications 5589/11, 12157/14, and 187,976.

Abstract: 462,516. Coal-distillation apparatus. KRETZ, T. July 17, 1936, No. 19816. Convention date, July 17, 1935 [Classes 51 (ii) and 55 (i)] In a coke oven in which the charge space lies between comparatively closely located internally heated walls, the latter are fixed and the coke chamber is provided with two walls between which the coal lies, these walls being adjustable relatively to each other to assist discharge of the coke. A radiation space from which the distillates are excluded is left between each of said walls and its corresponding heating- wall. In one form, Figs. 1 and 2, the stationary heating walls 1 enclose spaces into which are lowered charge containing chambers 8 formed by plates 11, 12 which can be opened for discharge of the coke from the side. These boxlike chambers are supported on the heating walls by projections 13, and have outlets 14 for the distillates leading to a common receiver 15. The heating gases pass from a flue 4 through heating passages 3 around baffles 2 to a discharge flue 5. In another form, Fig. 4, the heating walls 1 are enclosed in casings 16 forming the walls 11, 12 bounding the charge. These casings are moved relatively to the heating walls so as to vary the charge space, and facilitate discharge, and this is done by suspending the casings 16 by supports 17 from arms 19 which may be rocked by external shafts. An outlet 36 for the distillates is provided. Sheet metal plates may be arranged between the heating walls, and, at the end of the coking period may be moved to facilitate discharge of the coke. The wall plates may be pivoted as a whole, or in sections as in a venetian blind.
