Patent GB-982514-A (GB)
Title: Recovery of resorcinol
IPC: C07C37/52
Filed: 1963-12-11
Abstract: Resorcinol is recovered from the product of acid cleavage of m-diisopropylbenzenedihydroperoxide by distilling the cleavage product to remove low-boiling materials, heating the resulting product containing resorcinol to vaporize substantially all of the products other than the high-boiling condensation products, cracking the residual liquid mixture under reduced pressure and with the aid of steam stripping to vaporize further quantities of resorcinol, condensing the combined products of the vaporizer and the cracking process, and recovering resorcinol therefrom.  The vaporization may be effected at a temperature in the range from 200 DEG  to 250 DEG C., while the cracking may be effected in the range from 200 DEG  to 280 DEG  C., preferably at less than 500 mm. Hg, and particularly in the range from 50 to 250 DEG  mm. Hg.  Preferably the feed to the cracker is maintained above pH3 and the vapour phase before condensation is in the pH range from 4 to 7.  In an example, a product obtained by the distillation of the cleavage product to remove low-boiling constituents is fed through <PICT:0982514/C2/1> 1 to vaporizer 2 in which all the uncombined resorcinol and water are vaporized; the vapour and residue is fed to column 4, the vapour passing overhead via 8 and the liquid residue to cracker 5 where it is thermally cracked while steam enters at 6 to drive off the vapours, and tar is removed at 7; the combined vapours from column 4 pass into condenser 9 and are cooled directly by water sprayed through 10; liquid resorcinol flows via 11 to vacuum receiver 12 into which flows water obtained by condensing in 14 any vaporized cooling water; toluene is added at 17 to remove phenolic substances and the mixture is taken off via 18 for separation of the resorcinol phase.

Title: Fuze for mines
IPC: F42C7/06
Filed: 1964-12-02
Abstract: 1,041,140. Land mines. INDUSTRIE WERKE KARLSRUHE A.G. Dec. 2, 1964 [Jan. 31, 1964], No. 49037/64. Heading F3A. A non-metallic fuze for land mines comprises a casing 2 into which is screwed a base 1 and a cap 3. The casing is divided into two compartments by a diaphragm 4 secured in position by a flanged plate 5 carrying a firing pin 17 and supporting an evacuated glass vessel 18 housed in the cap. Foam material 20 protects the vessel 18. Diaphragm 4 is clamped between a plate 6 and a sleeve 7 housing a primer 9 and slidably mounted on a boss 8 upstanding from the base 1, which boss has a through-bore leading from the primer 9 to a detonator housed in an extension 8b of the base 1 and protected by a cap 25, preferably of soft silicone rubber. The vessel 18, which is spherical, has a stem extending into an extension 21 of the cap 3 and spaced therefrom by strips 19 of synthetic plastics, e.g. P.V.C. A plug 22 forms an air-tight seal for the space around the stem. Before laying the mine, movement of the sleeve 7 is prevented by a safety pin 11 extending through a bush 10 secured in the casing 2. The pin 11, when thrust inwards, engages by means of a collar 13 in a groove 14 of the sleeve 7, inward movement of the pin being limited by a resilient pull-ring 16. Firing of the primer is then prevented. To arm the fuze, the pin is withdrawn until further outward movement is prevented by a collar 12. With the pin 11 in this position, if the extension 21 or a protruding rod 24 is bent, the stem 18 breaks and the resultant decrease in pressure above the diaphragm 4 causes an upward suction, which throws the primer against the pin 17 and so initiates the fuze.

IPC: B41J23/32
Filed: 1968-10-22
Abstract: 1,185,749. Selective printing. ING. C. OLIVETTI & C. S.p.A. 22 Oct., 1968 [8 Nov., 1967], No. 50164/68. Heading B6F. An electro-mechanical transducer in the print out device of an accounting machine comprises a selectively energizable electromagnet with an armature and a positioning member which, in operation, shifts cyclically in a first direction to bring the armature up to the electromagnet at the instant when selective energization occurs, and also shifts cyclically in a second direction different from the first direction so as to effect selective mechanical operation of a control element depending upon whether the armature has been held by the electromagnet or allowed to retract by virtue of non-energization thereof. Type-setting mechanism.-Eight electromagnets 16 (two of which are illustrated) are energized selectively in accordance with an eight bit binary code. The armature 61 of each electromagnet 16 is pivoted to a fixed spindle 18 and has a pin and slot connection with a slider 62 biased by a spring 63 to move the armature away from the magnet. The positioning member is in the form of a rod 66 which engages in a slot 64 in each slider 62. An eccentric 72 moves the rod 66 cyclically in the first and second direction with an arrangement of connecting rods and levers 71, 73, 76 and 78. Depending upon whether the armature of a particular magnet 16 is retained thereby or allowed to retract, then a lug 92, on the slider 62 associated therewith, will be disposed beneath an extension 93 on a bar 81 or an extension 94 on a bar 82. Movement of the rod 66 in its second direction results in anticlockwise movement of the slider 62 which will cause a lever 86 to rock or remain where it is, and thereby control the tilting vane 107 of a type-setting mechanism via a further slider 98. A bail 109 is cyclically moved by a cam 118 on shaft 33 into and out of locking engagement with one of two notches 108 on each slider 98 depending upon the selective position thereof. Power actions.-Two other selectively energizable electromagnets are provided with a mode of operation similar to the above described type-setting electromagnets. First electromagnet (12, Fig. 1) controls a one revolution clutch (54) for driving the shaft 33, and remains energized until such time as a start signal deenergizes it. A second electromagnet (121), which has an associated mechanism identical with the mechanism associated with each electromagnet 16, Fig. 2, is adapted to command the striking of the character or type selected.

Abstract: 1396989 Semi-conductor devices INTERNATIONAL BUSINESS MACHINES CORP 2 Nov 1972 [10 Nov 1971] 50459/72 Heading H1K A charge coupled device comprises a semiconductor body 10 having in one surface 12 thereof a plurality of parallel rows 22, 23, 24 of alternating regions 14, 16 of different resistivity, an insulating layer 18 over the surface, including ridges 11 arranged between the rows, and electrodes strips 20a to 20e arranged on layer 18 perpendicular to the rows, so that each strip is associated with two regions 14, 16 in each row. In operation a voltage applied to a strip causes a stepped depletion zone having a greater depth under the region of highest resistivity, 16. The adjacent strip then has the voltage applied as that to the first strip is decreased causing transfer of minority carriers to the lowest part of the depletion zone beneath the second strip. The shape of the depletion zone ensures unidirectional transfer, the arrangement of regions 14, 16 in the rows causing transfer to the right in rows 22, 24 and to the left in row 23. The body may be of silicon, with regions 14, 16 doped with phosphorus by diffusion or ion implantation. The layer 18 may be of silicon dioxide and electrode strips of aluminium. In a further embodiment, the alternating regions are arranged at the end of each row to join the rows and produce a meandering form enabling carriers to be transferred throughout the length of the rows.

Automatic apparatus as described in the parent Specification for the continuous production of earthenware pipes 24, Fig. 1, in a vertically downward direction has modified means for receiving a pipe from a vertically reciprocable table 8 and setting it down on a conveyer 3, such means comprising a suction gripper 23 on a lever 76 pivoted at 73 to an end of a second lever 69 pivoted at 67 to a carriage 56 movable transversely of the conveyer 3 and supported on rails 55. Whilst the pipe 24 is being cut from the extrudate it is gripped by the gripper and the table 8 lowered whereupon an hydraulic motor swings the lever 76 and hence the pipe to a horizontal position; a second hydraulic motor then swings the lever 69 about its pivot 67 to a vertical position to bring the pipe to a set down position on the opposite side of the carriage. During such pivoting movements the carriage is moved along its track by an hydraulic motor 60, 61 on the carriage, the piston-rod 61 of which is secured at 64 whereby the pipe is conveyed to an appropriate position on the conveyer 3. During the return movement of the carriage to receive a further pipe the levers 69, 76 are returned to the position of Fig. 1. As shown in Fig. 3 there are two such carriages which operate alternately to transfer pipes from tables 8 disposed below a pair of extrusion cylinders 5, 6; the rail 55 is extended to both sides of the conveyer 3 enabling the pipes to be handled adjacent the conveyer.

Title: Improvements in "polymerization process"
IPC: C08G77/06
Filed: 1964-12-15
Abstract: Hexaorganocyclotrisiloxanes, in which at least one organic radical is a lower alkyl radical, are polymerized to siloxane gums by contacting them with iodine and aqueous hydriodic acid.  The reaction is effected by bringing the catalyst into contact with the siloxane, in solid or liquid form or in solution. The cyclic siloxane may contain, in addition to the lower alkyl radical(s), alkyl, aryl, aralkyl, alkaryl or halo-hydrocarbon radicals.  The catalyst can be subsequently removed by subjecting the polymer to a vacuum at room or moderately elevated temperature, or by heating, e.g. at 75 DEG  to 125 DEG  C. at atmospheric pressure. In a typical example (1) 0.25 pt. (by wt.) of a solution of 2.5 pts. of I2 in 2.68 pts. of 47% HI, was mixed with 100 pts. of hexamethylcyclotrisiloxane to yield after 16 hrs. a purple gum which, after being freed of the catalyst and volatiles by subjecting it to vacuum at room temperature, was mixed with fume silica and benzoyl peroxide and heat cured to an elastomer. Uses.-The rubbers can be used as insulation for electrical conductors, as cushioning means, as gaskets and as seals. Cyclotrisiloxanes containing 2 diphenylsiloxane units can be made by reacting, in the presence of pyridine, tetraphenyldisiloxanediol-1,3 with RR1SiCl2, in which R and/or R1 is a lower alkyl radical, any remaining radical being a saturated hydrocarbon radical with or without halogen substituent(s).
