The adjustment shaft includes a spindle 4 pivotally connected at 33 to a pin 1 which in turn is pivotally connected to the sealing frame 13 by means of a double lug 9. A compression spring 10 bears against the air duct at its lower end and can be adjustably pretensioned at its upper end by means of a plate and pin arrangement 11, 12. An adjustment head 2 contains the journalling for the worm-wheel 6 and shaft 7. A bush 5 surrounds the spindle 4. A star wheel 8 is connected to the end of shaft 7. Rotational movement of the wheel 8 is effected by means of a device, Fig. 3, which can be pivoted upwards or downwards by means of a lever 22 about a shaft 21 to effect respectively clockwise or anticlockwise turning of wheel; fork 20 linked with a tension spring 24 engages the spokes of the wheel, The device which is connected to the stationary casing 32 of the regenerator is surrounded by a gas-tight seal arrangement including bellows 31. Movement of the lever can be automatic in response to signals from apparatus measuring and monitoring the size of the gap between the matrix face and the sealing frame.

Teleprinters connected via an exchange can operate at more than one speed, and after connection being established at the lowest speed are switched in response to be a prearranged signal to operate at a higher speed. In one embodiment the connection is set up by dialling after the identity of the called station is requested at 50 Bd. in 5-unit code. The serial data on the line is converted to parallel and, if received in 5-unit code, is converted to 6-unit code to operate the printer. The calling station next transmits a command from its keyboard to change both teleprinters to a higher speed or to a 6-unit code. A circuit at both stations responds to this command to change the speed of the distributers and, if necessary, to inhibit the 5/6- unit converter. The calling station now transmits its identity (stored on punched tape) and the message. When the connection is cleared both teleprinters revert to operation for 50 Bd. signals. Start and stop bits may be added and deleted by the distributers.

An anode (which is suitable for use in a diaphragm cell for the electrolysis of aqueous solutions of alkali metal halides wherein the cell contains a plurality of parallel, vertically disposed anodes having their lower ends cast in a conducting metal) comprises a box-like structure open at each end of "Ti or similar metal", with at least two parallel plates having at least part of their outer facing surfaces plated with a "Pt group metal", with means at the lower edge to substantially prevent deformation of the structure on casting in the conducting metal base, the structure being such as to allow open access to the interior of the anode when the anode is in position in the cell. "Ti or similar metal" is defined as Ti, Nb or Ta or particular alloys of Ti, Nb or Ta. "Pt group metal" is defined as any of the metals Pt, Pd, Rh, Ru, Os or Ir or alloys of any two or more such metals. Fig. 2 shows an anode comprising parallel plates 2, 3 of Ti or similar metal. The outer facing surfaces of the plates are coated with Pt. Slots 6 in the lower edges substantially prevent deformation during casting. A graphite bar 8 also helps in this respect. Channel section members 10, 11 strengthen the structure. Cut-away portions 5 at the sides of the box-like anode allow open access to its interior. Anodes, instead of or additionally to being slotted at their lower edges, may be crimped. The lower edges may be provided with holes so as to key into the casting metal, e. g. of Pb or Pb alloy. They may be tinned or platanized to ensure good electrical contact. The box-like structure of the anode may be constructed by folding from a single sheet of Ti or similar  metal or may consist of two parts spot welded  together. The structure may be strengthened by ribbing, bending of the plates at their edges and/or by internal spacers. The cell base may be constructed of concrete, protected mild steel or protected cast iron. After the anodes have been cast into the cell base the casting metal may be protected with bitumen or concrete.

Abstract: 1411223 Pressure-wave liquid level indicators WILSON WALTON INTERNATIONAL Ltd 2 Nov 1972 [5 Nov 1971] 51613/71 Heading H4D The level of contents 2 in a container 1 is measured by directing ultrasonic vibration from a transducer 3 on to the contents' surface and measuring the time interval to reception of the echoes. A transducer 8 is provided and the time between transmission from transducer 3 and direct reception of the transmission at transducer 8 is measured. Transducer 8 is not responsive to the echoes from the contents' surface. The signals are amplified in unit 7, which also provide the energizing pulses for transducer 3, and signal 9, 10 from transducers 3, 8 respectively are then passed to Zener diode unit 11 which limits the voltages supplied from unit 7. After passing an interface unit 13, the signals are applied to multiplexer 14, receiving signals from other containers. Signals 9, 10 are passed to clocks 16, 17 respectively which give counts corresponding to the time intervals between transmission and reception at transducer 3 and transmission at transducer 3 and reception at transducer 8. The count of clock 16 is divided by the count of clock 17 in unit 18 to give a count indicating the contents' level independent of the velocity of the ultrasonic vibrations. The readings for several containers are read out sequentially by the multiplexer to displays 15. Fig. 2 (not shown), gives constructional details of the transducer mountings. A pipe 4 is preferably provided to contain the ultrasonic vibrations.
