Abstract: 1,100,726. P.C.M. systems. STANDARD TELEPHONES & CABLES Ltd. 12 Nov., 1965 [16 Nov., 1964], No. 46535/64. Heading G4H. A train of binary-weighted pulses, each of which may have positive or negative significance, is transmitted to represent the difference between a current analogue signal sample and the immediately preceding sample. Twelve binary weights are available for coding the difference between samples, but only five are used at a time, which group of five is used depending on the previous values of the coded difference. An input sample is applied to the base of T1, which together with T2, forms a longtailed pair comparator. C1 stores a charge corresponding to the amplitude of the preceding sample. A switching network PCC is set to select a group of five pairs of positive and negative pulses PP, PN, a positive or negative pulser being selected in accordance with the output of the comparator to steer appropriate charges into Cl until it is charged to the same level as the new sample. If the coded difference is less than 01111 for a plurality of cycles, this fact being stored in a ferrite core store CM, PCC is controlled to select the next lower group of pulsers to increase the accuracy of coding. If the coded difference reaches 11101 (equivalent to 29 in range 2-2<SP>4</SP>) the next higher group of pulsers is selected by PCC. The decoder is similar in operation. Incoming pulses select positive or negative pulsers PP, PN to alter the charge on Cl, from which the output is taken through a filter. A store CM and network PCC control the steering of incoming pulses to the appropriate group of pulsers in a manner similar to that employed in the coder.

A circuit to shunt one of a series of motorstarting resistors on reduction of armature current or effluxion of time comprises a shunt 23 carrying the armature current connected to a saturable transformer primary winding 20. When the motor is first switched on, the voltage induced in the secondary winding 205 causes a transistor 22 to conduct, energizing a relay 31, 31w controlling a contactor shunting one of the motor-starting resistors, the contacts 31 opening before the contactor closes. When the armature current falls, the transistor blocks and the relay releases closing contacts 31. If the current does not fall, after a time delay, the transformer saturates and the transistor again blocks. A resistor 21 provides a reverse current through the transformer to reset the flux. As the circuit is polarity sensitive, two such circuits connected in reverse series must be provided to operate on bi-directional current. A circuit is described in the Specification for successively shunting two series motor resistors.

Abstract: 1,240,182. Regenerative furnace cracking. UNION CARBIDE CORP. 11 Oct., 1968, No. 48193/68. Heading C5E. In a regenerative furnace process for cracking hydrocarbons in the presence of a diluent gas, e.g. steam, to form acetylenic and/or olefinic compounds, particularly acetylene and ethylene, the volume of diluent gas admitted to the furnace during the cracking step is progressively reduced so as to progressively increase the residence time of the feedstock in the furnace. This compensates for temperature drop during the cracking step and increases overall yield. The residence time may be further increased by also progressively reducing the feedstock volume, and in this case the feedstock-diluent gas ratio is preferably kept constant so as to maintain the feedstock at constant partial pressure. Detailed automatic control means for effecting the volume reductions are described. Suitable feedstocks range from ethane to gas oil, particularly propane.

These waveguide arms feed these signals to two ports of a hybrid magic "T" device 18, the output 19 from which comprises the difference of the two input signals and therefore corresponds to the TM 01  mode energy. This signal is phase modulated in phase modulator 20, e.g., by introducing equal time intervals of O and II radians of phase shift. This energy passes through isolating circulator 22 and beacon frequency filter 24, which rejects the communication frequencies and passes the beacon frequency which are both for example being transmitted by a satellite being tracked, and propagates via port 19 and hybrid 18 to the mode coupler slots where it causes TE 11  mode energy carrying the bearing information from the TM 01  mode at the beacon frequency to propagate via diplexer 16 to a receiver Rx. The sum of the signals at the input port of hybrid 18 appears at output port 21 and comprises the TE 11  mode energy unavoidably coupled out from mode coupler 14. The communication frequency component therein is reflected back from beacon frequency filter to the mode coupler 14 and half propagates towards the receiver therefrom, whereas the beacon frequency component pass through filter 24 to be absorbed in impedance 23 of isolating circulator 22. It is stated that the advantage over the prior art is that a greater proportion of TM 01  mode energy is transmitted to the receiver, and less TE 11  mode energy is coupled into the modulator 20.
