Title: Improvements in or relating to the storage of electrical signals
Inventor: CLARK THOMAS HAROLD
IPC: H04L12/54
Filed: 1956-05-18
Abstract: 832,630. Telegraph exchange systems. BRITISH TELECOMMUNICATIONS RESEARCH Ltd. May 14, 1957 [May 16, 1956], No. 15509/56. Addition to 830,509. Class 40 (3). In a telegraph exchange system in which incoming signals are passed at telegraph speed to a register from which they are applied at a higher speed for storage on a magnetic drum and are subsequently retransmitted at telegraph speed over appropriate outgoing lines, the signals on the drum are transmitted to and recorded on a, further magnetic drum recorder from which retransmission over the outgoing lines is controlled. The further magnetic drum recorder may be constituted by additional tracks on the drum on which the signals are firstly stored. The incoming message on a line I1 is set up on a register IR1, the address portion being passed via a gate A1 to an address register AR1 and the message being passed over switch CO1 to the first drum store RS1. The address portion operates a controller SC to produce a digital output which sets the crossbar switch S1 according to the called outgoing line, e.g. ON, if free and the signals on the drum RS1 are passed over the line BPN to line ON. If the line ON is busy, a signal passed from circuit ORN to the conductor RCN operates the controller SC to produce a different digital output which sets the switch S1 to connect the output of the drum store RS1 via gates WG, WA and switch S2 to the further drum store DBS. The input signals on the line I1 also pass via register IR1 to a capacity marker CM1 which indicates the filling of the first track by passing a signal over conductor CML to the controller SC to operate switch CO1 to the lower position to apply the input signals to the second track. When the required line becomes free, a signal over conductor RCN operates the controller SC which in conjunction with the address registered in the circuit BSR operates' switch S3 to connect the output from the appropriate tracks of the further store DBS to the line ON. When a track on the store DBS becomes full, a signal sent via a capacity marker (not shown) operates the controller SC which over conductor SL2 operates the switch S2 to select a free track, the number of which, together with the designation of the incoming line, is registered in BSR. If transmission and reception do not take place simultaneously at an outlying station the subsidiary circuit REP may be used by the controller circuit SC to send a message-acknowledgement signal or to request the repetition of a message address which appears to be erroneous.

Aldehydes are prepared by the hydroformylation of olefins with substantially no simultaneous formation of alcohols by a process which comprises hydroformylating an olefin with carbon monoxide and hydrogen at elevated temperature and at a pressure less than 200 p.s.i.g. and in the presence as catalyst of more than 1 mole of a square planar complex of monovalent rhodium containing a carboxylate ligand per 3600 moles of feed. Suitable complexing ligands contain a Group Vb or VIb donor atom and tertiary phosphines are preferred. A catalytic quantity of a carboxylic acid may be present to assist the stability of the catalyst on recycle. Preferred carboxylate ligands are those derived from aliphatic carboxylic acids containing less than 20 carbon atoms such as acetic, propionic and the butyric acids which are used in the examples together with the phthalate, cinnamate and p-fluoro benzoate ligands. Suitable olefin feeds have between 2 and 20 carbon atoms per molecule and in the examples those used are hexene-1, heptene-1 and octene-1. The preferred temperature range is 40‹ C. to 200‹ C. and the hydrogen to carbon monoxide molar ratio may be between 4: 1 and 1:4. In the examples hexane, heptane and octane, the hydrocarbons corresponding to the olefins are formed in small amounts and in Examples 1 and 3 hexan-1-ol and hexan-2-ol are formed.

Abstract: 939,174. Converting. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. April 13, 1962 [May 1, 1961], No. 15628/61. Class 38 (2). [Also in Group XXX] A rectifier feed circuit for supplying direct current to a load to which an alternating current is also supplied comprises a supply transformer T, a bi-phase rectifying circuit formed by Zener diodes D1, D2 and an output circuit, including choke L, which connects the D.C. voltage developed across resistor R to a load connected across points 2 and 3. The A.C. voltage supplied to points 2, 3 from a source (not shown) also acts in the rectifying circuit and tends to increase its D.C. output. This effect is reduced by the filtering action of choke L and resistor R and also, during each half cycle, by the reverse current action, of one Zener diode when the combined A.C. voltages applied to the other exceed a predetermined level.
