Abstract: 1359047 Hydroperoxides; phenols SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 31 July 1972 [2 Aug 1971] 36248/71 Heading C2C In a process for the preparation of organic hydroperoxides in which oxygen or an oxygencontaining gas is passed through a liquid reaction mixture comprising an organic liquid phase dispersed in an aqueous liquid phase, the organic liquid phase entirely or partly consisting of the compound to be converted into a hydroperoxide, the dispersion is maintained by stirring and by the presence of a finely divided solid which is insoluble in either of the two liquid phases. Phenolic compounds are prepared by cleaving a hydroperoxide or a mixture of one or more hydroperoxides prepared by the above process. Sulphur dioxide is the preferred catalyst for the cleavage reaction. In examples, hydroperoxides. are obtained by oxidation of cumene and meta-diisopropyl benzene in the presence of talc or barium sulphate prepared in situ. Resorcinol and meta isopropyl phenol are obtained by treating corresponding hydroperoxides with solutions of sulphur trioxide in acetone.

Abstract: 984,251. Sealing. ACME STEEL CO. Oct. 1, 1962 [Oct. 2, 1961], No. 37061/62. Heading B6P. [Also in Division B8] In a machine for banding packages 11, the circuit operating the sealing mechanism 16 is controlled through a rod 44 by the strap feed and band-tensioning mechanism 13 which comprises a feed-wheel 20 having a reversible drive and an idler wheel 28. A switch is operated to drive the feed-wheel 20, the drive being deenergized automatically after strap material 173 (or 10 in Fig. 1) is passed through the machine to project at 173a. Jaws 57, forming part of a mechanism 14 and which subsequently grip the strap end, are retracted to avoid fouling the strap. A seal 142 is fed from a magazine 141 by means of a bar 148 pivoted on a hinge 147. Jaws 136, in a mechanism 17, which subsequently gather the free end of the strap, are moved to their operative position, and circuits controlling the tensioning, gripping and sealing mechanism are prepared. By closing a pressbutton switch the operator feeds a required length of strap material out of the machine, encircles with it a package 11 moved into position on a roller conveyer 2, 3, and inserts the free end between guides 9. The free end passes between a roller 50 and blade 55 which comprise a strap straightening mechanism 48, and comes to rest against ledges on the gathering jaws 136. Closing a second press-button causes the jaws 57 to grip the leading end of the strap against the blade 55, and the drive to the feed-wheel 20 to be reversed to take up the slack in the strap. The tightening of the strap causes an arm 37, which passes through a shaft connected to the idler wheel shaft 29, to be moved against the action of a spring 40 and thereby to actuate a sealing control switch LS3 through the rod 44. The sealing is effected at 16 by jaws 82, 83 which crimp and deform the seal about the strap as shown in Fig. 10. The strap is then cut by a blade, Fig. 12 (not shown), associated at 15 with the sealing jaws. On being cut, the remaining strap end is drawn back through the straightening mechanism 48 before it is again fed through to the ready position at 173a. The parts 13-18 are pneumatically operated.

[Also in Division H4] A key-controlled multifrequency tone generator for a subscriber station has a number of oscillating circuits each tuned to the desired frequency by a capacitance and tapped inductance, the selection of the tappings being made by keycontrolled contacts arranged such that each capacitor is connected to only one' tapping of its respective inductance however -many keys are pressed. Fig. 1 shows two oscillation circuits for a 2 Î 1-outof-4 code, keys 1-16 each operate two switches, one in each circuit so as to select one tapping from each inductance Ue 1 , Ue 2 , the associated chain of series-connected break contacts being broken as the switches are made. The simultaneous depression of another key will either switch in another tap instead of the wanted one or make no difference, but will not short any parts of the inductance which might otherwise produce spurious or single frequency signals. In the embodiment shown in Fig. 2, a series chain of four switches is associated with each inductance and operated by a 4 x co-ordinate lever system having one lever or rod to each switch. Depression of a key actuates one rod of each co-ordinate and hence one tapping of each inductance. In both arrangements contact Tg connecting the supply is not closed until the tapping contacts have operated. The necessary feedback is provided by the transformer winding Ue 1 , Ue 2  in the transistor base circuit.
