Abstract: 249,380. Carter & Co. (Nelson), Ltd., and Carter, r. June 27. 192;n Fire, police, and like alarm systems and apparatus. - When the glass of a street box for fire, police and like alarm systems is broken, the door is automatically opened and a magnet o is operated to indicate at the fire or other station the number of the box and' sound an .alarm. When the glass C is broken a lever c<5>, which is held normally in contact with the glass 'by a spring c<7>, is released and an arm c<8> withdraws a bolt c<13> from a catch c<15> on the box. When the bolt is withdrawn, a spring-controlled plunger c<16> forces open the door until it is brought to rest by a pin c<19> located in a slot c<20> in a link c". As soon as the door opens, a link d attached thereto operates a slidable bar d<1> having a cam surface d<3> which raises a pin d<4> and disengages a catch d<6> from a notch d' on a slidable bar d<8>. The bar d<8> is connected to a pivotally mounted toothed sector d<11> which engages a pinion d<13> on the shaft of the armature of a magneto D and is normally forced within the box against the action of a spring d<14> by the door. When the door is opened the bar d<8> is released and the sector d<11> is rotated by the spring d<14> to operate the magneto. The magneto is in a circuit which includes the normally closed contacts F, f<2> but when upon operation the sector reaches its final position, these contacts are opened by a stud f and contacts F, f<1> are closed. The contacts F, f<1> switch a loud speaking telephone A and a sensitive microphone B into the line circuit. The component parts of the apparatus are mounted on a base plate E.

Abstract: 1,161,973. Measuring rate of flow. F. L.SMIDTH & CO. A/S. April 9, 1968, No.16980/68. Heading G1A. [Also in Division G3j The weight per unit time of moving bulk material is measured by allowing the material to fall freely through a vertical shaft 7 and measuring the absorption by the falling material of radiation from a radio-active source 8 using a detector 9. In the arrangement shown, the cross-section of the material measured is chosen so that the absorption is a logarithmic function of the flow-rate. The detector output is fed to a regulator unit 10 which operates on drive 6 to control the speed of the conveyer 3, feeding material to the shaft, so that the amount of material supplied per unit time is either constant or varying according to a predetermined programme. Alternatively, the flow to the conveyer 3 from silo 1 is controlled by the regulator operating on slide gate 2.

Abstract: 568,981. Light beam dividing apparatus. SCOPHONY, Ltd., ADAMS, A. E., LEE, H. W., JONES, P. L. F., and WIKKENHAUSER, G. Oct. 15, 1943, No. 16995. [Class 97 (i)] A device for dividing a beam of light into two beams in different directions, e.g. at right angles to one another, comprises two solid transparent bodies of substantially the same refractive index, having closely adjacent faces separated from one another by a thin layer of transparent material of a different refractive index, the refractive indices and the angle between the surfaces and the incident beam being such that the major part of an incident beam is transmitted through both bodies while a relatively small part is reflected at the surfaces. One embodiment of the invention comprises two right-angled isosceles triangles of extra dense flint glass having their hypotenuse sides cemented by a thin layer of Canada balsam to form a cube. The major portion of a beam of light incident on the cube is transmitted undeviated, while about ¢ of one per cent is deflected in a direction at right angles to the incident beam. The reflecting layer may be a liquid, colloid or a thermosetting material and should preferably differ in refractive index from the transparent bodies by at least 0.1.

Patent GB-1009031-A (GB)
Title: Improvements in and relating to the extraction of hydrocarbons
Inventor: WIENER HANS BERTHOLD
IPC: C07C7/152
Filed: 1963-05-01
Abstract: Aromatic hydrocarbons, e.g. benzene and xylenes, are separated from paraffins by contacting the mixture of liquid hydrocarbons with an aqueous solution of a salt of a heavy metal in the presence of an olefin, present in sufficient amount to facilitate the absorption of the aromatic hydrocarbon by the heavy metal salt solution, to extract the aromatic hydrocarbon, separating the aqueous solution from the paraffin, recovering the aromatic hydrocarbon and olefin from the aqueous solution thereby regenerating the aqueous solution. Specified heavy metals are copper, mercury and silver which may be used as a fluoborate or fluosilicate.  The olefin, e.g. hexene-1, octene-1 or decene-1 may be added in admixture with the other hydrocarbons or the aqueous solution or may be added to a mixture of the hydrocarbons and aqueous solution. The aromatic hydrocarbons and olefin may be recovered (1) together from the aqueous solution, e.g. by distillation; (2) by selective decomposition of the complexes formed in the aqueous solution; (3) by contacting the aqueous solution with an organic solvent immiscible with the aqueous solution.  In the example benzene is separated from heptane by using an aqueous solution of silver fluoborate in presence of octene-1.
