As shown, the casings 1, 2 comprise cylindrical concentric shells and the curtains or screens 17-24 between the respective chambers each comprise a radially extending row of spaced-apart tubes with the screens 17-20 incorporating spray nozzles 25-28. The screens alternatively may each comprise perforated plates or a labyrinth arrangement of plates 15 and 16 are baffles which protect the shell 2 against the incoming steam. 29-32 are other baffles which protect the relatively hot shell 1 against the effects of the cold spray from nozzles 25-28. In use, steam to be desuperheated enters the expansion chambers 3, 4 via openings 11, 12 in the shell 1. From the chambers 3, 4 the steam passes through the screens into heat exchange chambers 5-8 and then into outlet chambers 9-10 to be discharged via openings 13, 14 in the shell. The expansion chambers may be defined entirely by arcuate baffles (119, 120, Fig. 4) which may be steam permeable; thus dispensing with the screens 17-20. In this case separate spray nozzles (127-130) are provided.

Springs; eccentricactuated pumps; leveractuated pumps; stroke, varying; delivery pipes ; regulating delivery by throttle valve. - A pump for fuel &c. has an adjustable throttle-valve 20 in the delivery pipe and a yielding element in the plunger-actuating mechanism, so that the stroke of the plunger varies with the adjustment of the valve. In one form, the plunger 24 is actuated by a lever 27 connected at one end to an eccentric-rod 29 and held at the other end between a. stop 34 and a spring-pressed pin 35. If the valve 20 is adjusted so as to obstruct the delivery and increase the pressure in the pump, the plunger moves the lever 27 out of contact with the stop 34 and the stroke is shortened. The spring 38 is adjusted by means of the plug 37. In another form, the end of the plunger is enclosed in a casing reciprocated by the eccentric, and a spring is inserted between a collar on the plunger and the inner wall of the casing. The valve 20 may be adjusted by hand or governor.

Title: Improvements in or relating to the production of titanium diboride
Inventor: WOOD ANTHONY ARTHUR ROBINSON
IPC: C01B35/04
Filed: 1961-05-15
Abstract: Titanium diboride is produced by heating at a temperature above 1350 DEG  C. a slug of shape such that the ratio of surface area to solid volume is at least 1.5 times as great as that for a solid cylinder of the same length and of diameter equal to the maximum cross-sectional dimension of the slug, said slug comprising an intimate mixture of boric oxide, carbon and titanium dioxide.  The cross-section may be tubular, channel, cruciform, star or semi-circular with or without a corrugated surface. Preferably the bore is longitudinal, the walls being of uniform thickness.  The slug is prepared by heating the ingredients in a mould at a temperature of 300-1000 DEG  C. and subjecting to lengthwise compression, or alternatively, a pointed cylindrical or other rod may be driven into the slug.  The material may be longitudinally confined by a closed end of the mould and at the other end by a disc through which a rod can pass.  The diameter of the rod may be up to 2/3 that of the slug.  Tubular slugs may also be produced by extruding at 400-1000 DEG  C., or cold pressing followed by heating to 400-500 DEG  C., or by compression moulding at above 300 DEG  C., or by jigging or drilling at room temperature. The TiO2 may be mineral rutile, titanic oxide or preferably anatase, the carbon may be graphite or carbon black in stoichiometric excess up to 5%.  Up to 50% excess B2O3 may be present and in addition a carbonaceous binder, e.g. molasses.  Specification 1,004,585 is referred to.

Title: Impedance measurement
IPC: G01R19/165
Filed: 1972-04-18
Abstract: 1395392 Impedance measurement HEWLETT-PACKARD CO 18 April 1972 [7 June 1971] 17776/72 HeadingGlU A circuit for use in determining the impedance of a device under test (connected between terminals 39, 21) incorporates a driving current circuit (including transformer 11), a current channel (incorporating transformer 18) and a voltage channel (incorporating transformer 23). The primary of the current channel transformer 18 is connected in the current path between the secondary of the driving current transformer 11, to whose primary is connected an A.C. source 14, and the test device. The secondary of the current transformer 18 thereby provides an output signal representing the current in the test device. The primary of the voltage channel transformer 23 is connected across the test device, and its secondary provides an output signal representing the voltage across the test device. The invention is characterised by the incorporation in the circuit of a current balancing circuit, including an additional winding on the driving current transformer 11 in series with a capacitor 32, all in shunt with the primary of the transformer 18. This circuit balances out current flow in transformer 18 due to parasitic capacitance between the test terminals 39, 21. The balancing circuit may include a  delay line 33. A coupling transformer 35, 36 may be included to add to the voltage signal a signal to compensate for unwanted volt drops and stray coupling between the energizing, current and voltage circuits. The circuit may form part of a probe having a tubular casing Fig. 3 (not shown), within which the various circuits are shielded from one another and which carries at one end a split guard ring 37, providing the terminal 39, surrounding the other terminal 21. The whole unit is for use with an impedance-frequency or phase-frequency analyser, the A.C. source 14 being of swept frequency. The signal from the current channel is applied to the reference input of the analyser and the signal from the voltage channel is applied to the measurement input.

Combinations of interdependent valves.-Two aerating chambers 12, 14 connected by a pipe 13 fitted with a check-valve 16 are supplied with gas through a valve G which is normally open. On turning a cam-shaft 43 by means of a handle 44 the valve G is closed and a water-inlet valve W, .communicating with the chamber 12 through a pipe 23 and check valve 24, and a snift valve S and discharge valve D communicating with the chamber 14 are opened. The gas is thus allowed to escape and the chamber 12 filled with water. The pipes connecting the chambers 12 and 14 with the shift valve are provided with a cheek-valve which prevents the gas which is being snifted from the chamber 12 from passing to the chamber 14. The valves W, D, S are then closed and the valve G opened, allowing gas to enter and aerate the water and drive it through the pipe 13 into the vessel 14.
