Title: Improvements in or relating to telecommunications systems
IPC: H04Q3/54
Filed: 1966-09-22
Abstract: 1,121,825. Automatic exchange systems. SIEMENS A.G. 22 Sept., 1966 [23 Sept.. 1965], No. 42267/66. Heading H4K. During a connection between a calling and called subscriber, which connection may be a ringing connection, data may be sent to the called subscriber in accordance with instructions sent by the calling subscriber as a supplemont to the called subscriber's directory number, it being necessary to translate the supplement to produce the data sent to the called subscriber. The supplement may be sent by the calling subscriber, such as TN1 Fig. 1, by using a tone sending keyset or data set D1 which either does not interfere with or co-operates with the customary dial. The local register REGA, having received a called party designation, waits a given time to pick up a supplement should one be sent. For a call from a local exchange A to a distant exchange B, common controls UMWA, UMWC may communicate direct over a link d. In any event call data is transferred to exchange B involving local register REGC, control UMWC, and relay circuits RSB, RSC. The supplement, received and converted in UMWC can be used for the following purposes. It may indicate to a substation being rung the identity, either by code or by name, of the calling subscriber, such signalling being effected during the pauses between bursts of ringing current. It may indicate either audibly or visually in code or by name the wanted one of a number of people available over the substation being rung. It may identify a particular telemetry source available over a substation. It may elicit the called substation identity and establish the credentials of the calling subscriber in gaining access to a remote control or telemeter situation. It may be used to provide an automatic ringing service with the particulars as regards time and number to be called. A calling party identity, intended for display, can be registered so that if a subscriber is absent when called he can be given a record of attempted calls during his absence. If a subscriber is absent but available elsewhere on the exchange, calls to him may be automatically transferred with a possible change of individual coding if he is one among a number on the different extension. Automatic announcements may be provided for groups or individuals who may also leave messages to cover their absence. If a subscriber does not want to be disturbed by ringing he can arrange that, when called, a data receiver, such as D2 at station TN2, is connected up so as to record any message that may be left and take a note of the calling subscriber's identity. Substation apparatus.-Fig. 2, not shown, discloses a bridge circuit which connects up a tone sounder during intervals of ringing current so that identifying tone signals may be sent during these periods.

Title: Process for production of n-ª-olefins by the alkyl metal technique
Inventor: LINDEN RONALD CORNELIUS VANDER
IPC: C07C2/88
Filed: 1964-10-27
Abstract: Alpha-olefines are obtained by subjecting a trialkyl aluminium to a growth reaction with a C2-C3 olefine, distilling the trialkyl aluminium product to obtain a distillate containing tri-(C2-C8 alkyl) aluminium which is subjected to further growth, e.g. by recycling, and a bottoms containing tri(C10+)alkyl aluminium which is subjected to a displacement reaction to recover olefine product.  Distillation is effected using a short residence time, evaporator or a molecular distillation technique at 100-600 DEG  F., 10-6-10 mm. pressure, and a residence time of 0.01-10 seconds.  The displacement is effected in two stages, in the first using octene-1 followed by distillation of C10-C18 products from C20+ and aluminium trialkyls, then using ethylene to recover higher displacing olefines, higher product olefines and aluminium trialkyl for recycle.
