Filed: 1929-10-30
Abstract: Apparatus for carrying out reactions with hydrogen particularly under pressure is constructed of or coated with zinc alloys in those parts of the apparatus which come into contact with the hot <PICT:0341153/III/1> reacting materials.  Alloys of zinc with copper, manganese, nickel, iron, cobalt, aluminium, and silver are referred to.  The invention is particularly applicable to destructive hydrogenation, and in this case the proportion of hydrogen should be increased when the raw materials contain a high percentage of sulphur, so that the reaction mixture does not contain more than 2 or 3 per cent by volume of sulphur compounds.  The figure shows an apparatus comprising a preheating coil G of chromium steel, high-pressure reaction vessel B of iron, and condenser D, all of which have a lining a composed of an alloy of 62 per cent of copper and 38 per cent of zinc.  Examples are given relating to the destructive hydrogenation of oil &c., and to the synthesis of ammonia and of methanol.

Title: Circuit for comparing two electrical waveforms
IPC: H03D13/00
Filed: 1974-07-26
Abstract: 1462408 Phase and frequency detectors; digital frequency meters MULLARD Ltd 26 July 1974 33139/74 Headings H3A and H3H Apparatus for detecting the phase and/or frequency difference between the input signals A, B comprises a phase comparator, e.g. bistable 8 which provides an output E whose magnitude depends on the difference and means e.g. 9, 6 for reversing the phase of either one of the input signals if two consecutive similar transitions of one waveform occur without an intervening similar transition of the other. If the two signals are at the same frequency, bistable 8 is set by a positive going transition of one input, and reset by a positive going transition of the other. In this condition two further bi-stables 9, 10 provide "0" levels at their outputs and the two signals A, B are applied to bistable 8 via EXCLUSIVE-OR gates 6, 7 without inversion. If the frequency of signal A is higher than that of signal B, then a second positive transition of signal A will eventually occur before bi-stable 8 has been reset by signal B, and bi-stable 9 will be switched to give a "1" output which causes gate 6 to invert subsequent input pulses at A. This switching repeats each time the phase difference increases by #. Similarly if B is higher the phase of signal B is inverted by 10 and 7. The output E from bi-stable 8 may be fed to a lowpass filter 11 to give an analogue output at 4, or the outputs G, H from bi-stable 9, 10 may be connected to an up/down counter which indicates the frequency difference.

Abstract: 522,519. Friction clutches ; valves. KIEP, J. N., and SINCLAIR, H. Nov. 16, 1938. No. 33368. [Class 80 (ii)] [Also in Group XXIX] In a friction clutch operated by centrifugal force generated in a body of liquid rotating coaxially with the clutch elements, the liquid is fed from a reservoir chamber 11, Fig. 1, to a pressure chamber 10 through apertures 40 in a disc 32 by means of one or more scoops 41 and can return to the reservoir chamber through drain holes 27. The delivery ends of the scoops are surrounded by a collecting cone 39 mounted on the driven disc 32 which carries the friction plates 28 and divides the drain 12 mounted on the flywheel 16 into pressure and reservoir compartments. The drum carries the friction plates 25 and is provided with external cooling fans 14, 15 and internal ribs 22 in the pressure chamber. The scoops are mounted on a screw-threaded sleeve 43 which may be turned by a lever 46 to move the scoops into contact with the ball bearing 38 to interrupt the liquid flow to the pressure chamber. The control lever may if desired be moved further to move the hub 33 mechanically to disengage the clutch. In Fig. 2 the scoop 92 is held by a spring 99 in a position such that its inlet is clear of the rotating ring of mercury in the channel 95 until the motor shaft 50 is rotating at such a speed that a lug on the scoop is dragged by the mercury to rotate the scoop into an operative position with a snap action. The scoop delivers mercury to the pressure chamber comprising an inflatable bag 67 and indentations 74 in a plate 71 by way of a channel 73. The pressure and reservoir chambers also communicate by way of a drain hole 76 and a drain hole 75 into which enters an adjustable needle 75A. A lubricator 83 is provided for the bushes 54 and oil exuding into the clutch escapes through channels 65C, 65A. In a cone clutch, Fig. 5, the delivery end of the scoop 131 is fitted with a ball valve 136 held closed by a spring 140 until the speed reaches a particular value. When the valve is open the liquid pressure acts on the whole projected area of the ball and prevents hunting.

In the form shown the boiler forms part of a nuclear reactor marine power plant and is housed together with the reactor in a cylindrical pressure vessel 12 closed by a bolted head 14 and encased in insulation 15. The reactor core 16 is disposed in the lower part of the vessel and is controlled by rods 18. A cylindrical baffle 28 extends upwardly from the reactor top and terminates below a level 22 at which coolant liquid is maintained in the vessel. The annulus 30 between the baffle and the vessel walls contains a bank 44 of helically wound generating tubes. The bank consists of a number of tubes connected in parallel between inlet headers such as 32 and outlet headers such as 34. The tubes from the inlet headers pass directly to the bottom of the bank adjacent the vessel wall and then wind upwards to the top of the bank, the pitch of the helices decreasing from the innermost outwards so that all the tube coils are of the same length. The tube coils are supported from the head 14 so that by unbolting the latter it can be lifted with the tubes from the unit.
