Title: A circuit arrangement for sending signals through a junction line between two automatic telephone exchanges
IPC: H04Q3/00
Filed: 1961-03-20
Abstract: 970,273. Automatic exchange systems. TELEFONAKTIEBOLGET L. M. ERICSSON. March 20, 1961 [March 19, 1960], No. 10156/61. Heading H4K. An inter-exchange call may be released from either end of the junction, the two wires (or channels of a 4-wire line) of which serve for the passage of clearing signals in either direction. In Fig. 1, a junction L1 terminates in similar relay sets U11, U21, the circuits of U21 being shown in Fig. 3. It should be noted, however, that the wire a1 of V11 is connected to the wire b1 of U21, and vice versa. An incoming calling signal over wire a1 operates relay R1. A marker M is seized as well as a register REG2, and the latter returns an impulse over wire cl to operate R6, R7, whereupon holding relay R5 pulls up and releases R1. An answering signal from REG2 over wire b1 stops the calling signal. If no idle register is found, the calling signal operates relay R2 after an interval imposed by condenser C2 and resistance r2. Relay R3 pulls up and sends over wire b1 a clearing signal which is long enough to operate relay R2 in U11, with the result that R3 energizes to send a reply clearing signal. In both relay sets R4 operates after an interval and interrupts the clearing signals. The release of R2 disconnects holding relay R5. If the call fails to be completed by the register REG2 the clearing operations are initiated by the release of R7, which connects up R3. On an established connection over the link SR, Fig. 1, holding relays in switches SA, SB are held over the c wires and are disconnected on the arrival of clearing signals at the relay sets U21, U22. In another embodiment, Fig. 4 (not shown), a 4-wire junction terminates at each end in TDM equipment, and VF signals are employed for calling and clearing.

Title: Improvements in or relating to methods of treating peat and similar ligno-cellulose materials
IPC: C10F5/00
Filed: 1949-04-14
Abstract: Crude saw mill waste and similar lignocellulosic materials containing water are broken down from the colloidal condition to facilitate de-watering, by simultaneously heating the material under pressure and admitting oxygen or oxygen-containing gas thereto, the heat being wholly or partly supplied by the exothermic oxidation of the material.  Basic reacting substances such as carbonates, hydrates and oxides of the alkaline metals and/or the alkaline earth metals, or catalysts such as iron oxides or vanadium oxides may be added to assist the oxidation, and the mass should be agitated either mechanically or by the admission of steam and/or the gas.  The process may be effected continuously or intermittently, and the entering material may be pre-heated by heat-exchange with the treated material or with vapours therefrom. The oxidation may be effected in an acidified phase by adding organic and/or inorganic acids to the material, the resulting hydrolysis of the cellulosic matter forming fermentable sugars. Pressures of from 10 to 200 atmospheres, and temperatures of from 150 DEG  to 300 DEG C, and gases containing from 90 to 95 per cent of oxygen are referred to as suitable for the process, although it is stated that oxidation may occur at a temperature as low as 50 DEG C, and that air may be used as the oxidizing gas provided that the pressure of the steam and non-condensable gas supplied to the material is correspondingly increased.  The oxidized material may be mixed with crude peat (10 to 15 per cent by weight calculated on a dry basis is mentioned), the de-watering property of the material not being affected by the addition.  Specification 3998/15, [Class 50], is referred to.
