Abstract: 1,052,741. Electrically released switches; switches held set and freed mechanically ALBRIGHT (ENGINEERS) Ltd. June 7, 1963 [March 8, 1962; April 11, 1962], Nos 9017/62 and 14023/62. Heading H2B. An electric switch which is subsequently closed and opened on successive energizations of an electromagnet has a latch which holds the contacts in the closed position and is moved at each operation to effect change-over of a contact set in series with the solenoid of the electromagnet. On energization of solenoid 2 or manual operation of a knob 8 the armature 6 moves to the right to move a member 12 in the same direction. A sleeve 19 attached to the member 12 has projections 38 having cam faces 39 which engage a latch member 41 to move it away from a fixed stop 43 and then rotate it through 90 degrees. The member 41 is mounted on a shaft 17 carrying the resiliently mounted main contact bridge 24 which engages fixed contacts 32, 33 as the shaft 17 is moved by the latch member 41. The latter has a cam ring 42 which as the member is turned acts on a spring-biased pin 41 to operate a change-over contact set (Fig. 3, not shown) in series with the solenoid 2. The member 41 is shaped so that after one 90 degrees turn its end will abut the stop 43 (Figs. 6 and 8, not shown) to hold the contacts 24, 32, 33 closed and after the next 90 degrees a slot 46 in the member 41 allows it to return to the Fig. 1 position as biased by springs 36, 48.

An extrusion die head for the production of plastics tubes comprises a mandrel 1 and a die ring 2 radially movable to modify annular orifice 3 by adjustment of two stops 12, only one shown, against which the ring is urged by one or more resilient members, e.g. compression springs 13. Die ring 2 is free to slide radially within a fixed block 6, and as shown, is moved by rotation of one or both stops 12 whose axial movement is translated into a radial movement by the co-operation between a conical portion of each stop and a ball 14. Also, as shown, at each location of a stop 12 or spring 13 two bores in block 6 are provided, one being axial and the other radial. A stop 12 may therefore be replaced by a spring 13 and vice versa. Stops 12, when screw-threadedly engaged with block 6, may be rotated by the insertion of a tool in socket 15. Alternatively adjustment of stops 12 may be effected hydraulically.

A method of transforming an electrical signal in the form of a sequence of binary digits into a form having lower disparity comprises recoding bytes of n binary digits in the sequence as bytes of m binary digits where m > n and both are positive integers, some but not all of the m digit bytes having minimum disparity and successive m digit bytes with non zero disparity having disparities of opposite sign. For the case n = 5, m = 6, data in the form of five bit bytes is fed to a register 2 and a " 1 " bit counter 3 of an encoder-transmitter, the counter having four outputs M 0 , M 1 , M 2 , M 3  for zero or four " 1 " bits, one or five " 1 " bits, two " 1 " bits and three " 1 " bits respectively. The counter is controlled by clock pulses from a unit 4, the pulses being divided by five and applied via a delay 8 to reset the counter after each byte. Five bit bytes having unit disparity are converted into six bit bytes having zero disparity by a circuit including " AND " gates 14, 17, 27 and fed to an output register 30. Other five bit bytes are fed to a translator 16 in the form of a diode matrix including twelve " AND " gates and six " OR " gates where they are converted into six bit bytes, alternate bytes being inverted by an inverter 18 to form bytes having disparities of opposite sign.

A subscriber's line circuit requires more current to operate a relay, such as B 1 , B 2 , than it is necessary to send round the loop to the substation circuit indicated by impedance RL, a symmetrical four-pole network, 1, 2, 3, 4, being put in the line to shunt a proportion of the line current in the exchange end of the loop and to do this regardless of loop polarity. With an onhook condition both transistors T 1  and T 2  are cut off. With an off-hook condition, and with the polarity of battery in the line circuit in one sense, transistor T 1  remains cut off but is shunted by diodes DZ 1  and D 1 , T 2  conducting to set up the shunt path in accordance with bias produced from back conducting Zener DZ 2  in the subscriber's loop. The proportion of current shunted varies in accordance with the loop impedance. With battery supplied in the opposite sense the circuit acts to the same effect but with T 1  conducting and T 2  cut off. The shunt path provides a high impedance to voice frequencies on the line, the presence of Zener diodes in the loop providing small impedance.
