Patent GB-268805-A (GB)
Abstract: 268,805. Posternak, S. March 31, 1926, [Convention date]. Albumenoids.-A mixture of three acid bodies containing phosphorus and iron is obtained from de-fatted and coagulated egg-yolk by digesting with pepsin in presence of a mineral acid to a desired extent, stopping the digestion by neutralizing the acid or by replacing it by an organic acid (as by adding sodium acetate), separating the precipitate, digesting it with trypsin in a feebly alkaline medium, filtering, and treating the filtrate with an alkaline earth salt and alcohol or with a heavy metal salt. The heavy metal compounds may be treated with an alkali salt to obtain the corresponding alkali compounds which yield the free organic acids by treatment with a mineral acid in alcohol solution. In the examples, defatted, powdered egg yolk is digested with pepsin in presence of hydrochloric acid at 37-40‹ C. until dissolved. Sodium acetate or carbonate and acetic acid are added, the separated precipitate digested with minced pancreas in presence of sodium carbonate at 40‹ C., acidified with acetic acid, and filtered. To the filtrate is added calcium chloride or acetate and alcohol to precipitate the calcium salts of the organic acids. Alternatively lead acetate may be added, the lead salt obtained being then decomposed with sodium carbonate solution; the filtered solution is concentrated in vacuo and precipitated with alcohol. The sodium salts thus obtained mav be converted into the calcium salts bv adding calcium chloride or acetate and alcohol. or into the free acids by treating with alcohol containing hydrochloric acid: the precipitate is washed with alcohol and dried. It is stable to cold acids but unstable to alkalies.

Abstract: 889,393. Automatic - exchange systems. AUTOMATIC TELEPHONE & ELECTRIC CO. Ltd. July 20, 1960 [Aug. 18, 1959], No. 28138/59. Class 40 (4). In a system in which calls for subscribers of an automatic ex - change who are absent from their stations are answered by an operator at a manual switchboard, connections between the line circuits of the subscribers concerned and the switchboard are effected by a line connector arrangement including synchronously operated switches at the exchange and the switchboard and a number of links less than the number of subscribers involved, the setting up of such a connection being initiated by ringing current on a called subscriber's line. As shown, the + and - wires of the subscriber's line are extended from the M.D.F. to a line connector unit LCU. When ringing current is connected up by operation of relay H (not shown), in the final selector FSC, the presence of rectifier MR1 ensures that unidirectional current pulses are applied to relay LR, which then operates, bringing up the self-holding relay LL to the ringing battery. A free link L will have been already allotted by allotter LA, and when LL applies ground to the start circuit ST this link is seized and the switches SSB and SSA are synchronously stepped to the called line circuit, the cut-off relay LK (not shown) pulling up to switch the line circuit through to the answering switchboard AS, and to release relays LR and LL. The power supply for the switching equipment SA and SB and the link allotter LA and start circuit ST is provided by a battery in the answering sevice office. Only if ringing current is applied to a line circuit with relay H up and F (not shown) normal can a connection to the switchboard be set up, since LL cannot be operated in any other circumstances. If cross-bar switches are used in the line connector, the contacts lk may be associated with the switch mechanism instead of being provided by additional relays.
