Abstract: 575,311. Automatic exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO., Ltd., and BAKER, G. T. Jan. 12, 1944, No. 22428/45. Divided out of 575,294. Drawings to Specification. Class 40 (iv)] In a tandem office of a network in which all inter-office calls are controlled by an operator at a central point, the junctions to the operator terminate in incoming selectors which are normally prepared for operation and the junctions to more remote offices terminate in repeaters comprising non-numerical switches which give access to junctions to the control office, to other outlying offices and to the subscribers of the tandem office. A call from a remote office causes the automatic connection of the junction over which the call arrives to a tandem/operator junction, the incoming selector of which is disconnected but is subsequently re-connected by the operator to enable her to set up the connection. If it is set to a position indicating the group of junctions over which the call arrived at the tandem office, the original condition, in which the two junctions are connected together, is restored. If the call is not to revert, it is completed by the non- numerical switch for which the incoming selector of the tandem/operator junction acts as a marker. If a call for a remote office originates in the tandem office, the operator is called over a local link, but the call is established by means of the non-numerical switch associated with the junction leading to the desired remote office. The invention is described with reference to a system identical with that described in Specification 575,294. Specification 518,877 also is referred to.

Title: Improvements in or relating to molybdena hydrosols
Inventor: BILISOLY JULIUS PHILIP
IPC: B01J23/28
Filed: 1953-08-14
Abstract: A concentrated molybdena hydrosol containing 40-300 grams molybdena per litre and having a pH of from 0.1 to 1.4 is prepared by contacting an aqueous solution of a molybdate with an acid-washed synthetic cation-exchanging resin.  Solutions of ammonium, sodium, or potassium molybdate may be employed.  Air drying of the hydrosol yields a glassy, horny, amorphous mass.  In examples, ammonium molybdate solution is passed downwardly through a bed of the resin to form a blue hydrosol; the addition of hydrogen peroxide to the molybdate solution maintains the molybdenum in its higher valency and provides an orange-yellow hydrosol; the solubility of ammonium molybdate may be increased by adding ammonia to the original solution.  Tables are given showing the pH, specific gravity, and MoO3 content of various hydrosol fractions.  The hydrosols may be used to prepare hydroforming catalysts as follows (a) by mixing the molybdena hydrosol with alumina hydrosol, with or without silica hydrosol, and oven or spray drying the product (b) by impregnating wet or dry alumina, which may contain silica, with the molybdena hydrosol.  The alumina hydrosol may be formed by hydrolysis of an aluminium alcoholate; alumina of wide bore diameter is formed by hydrolizing aluminium amylate solution with a 1 per cent solution of hydrogen fluoride, filtering, pelleting, and steaming the product. Specification 645,703 is referred to.
