Abstract: 1,258,064. Fluid logic and switching circuits. BERGWERKSVERBAND G.m.b.H. Nov. 27, 1968 [Dec. 14, 1967], No. 40852/68. Heading F1P. A pneumatic logic system has input pulses emanating from a plurality of pairs of measuring devices at spaced stations k = 1, k = 2, k = 3 Fig. 1b associated with spaced pairs I, II Fig. 1a of self-advancing wire roof supports 6 associated with a conveyer 2 and rams 4 and which devices serve to measure the deviation of the actual line 9 of a longwall face with the desired line 8, and the output of the logic system serves to restrict the cutting operation to the out-of-line position of the coal face e.g., between stations k = 1 and k = 3; the input pulses which are referred to as forward (positive) and rearward negative pulses according to whether they are produced by extension or retraction of the ram of a braced support I or II are algebraically summed and form the inputs 400, 401 Fig. 3 of a storage device the output of which when released forms said output serving to restrict the cutting operation. Assuming only one of a pair of support units I, II is unbraced, advanced and reset at a time then with say support II braced a continuous signal is supplied to line 3 on Fig. 2 and when due to movement of ram of II a rearward pulse R II  appears on a line 301 at the non-negated input of an AND element 302 no signal appears at the output 307 of OR element 306. If however a pulse R 1  appears on line 309 then a signal appears at 307. Forward pulses are similarly produced at the output 307a of OR element 306a. Outputs 307, 307a form inputs 401, 400 of a shift register having seven storage devices and a signal output 402 which switches off the conveyer advancing rams associated with the measuring station. A signal appears at 402 if at least storage devices 1, 2, 3 are occupied by a signal. The logic circuit of a station k is shown in Fig. 4a wherein a longwall signal line connects all the two-way shift registers in a ring circuit. If a signal from a preceding register appears on line 500 it is transmitted through a pulse former J k  and a line 501 to a storage device A k1 . Further storage devices A k2 , A k3  receive forward and rearward pulses from the measuring station. If storage device A k1  has accepted a signal and has transmitted onwards via AND element B k1 , then the outputs of storage devices A k2  and A k3  become cut-off by way of B k2  and B k3  whereby pulses arriving simultaneously and processed in succession. The output signal at B k1  proceeds by way of OR element Z into the R input of the shift register and sets it back one unit. At the same time the signal is fed back via the time delay element T k1  to the erasure input of A k1  and erases A k1  after a period determined by T k1  so that only such pulses as may be stored in A k2  or A k3  can be processed. In a similar manner the storage devices A k2  and A k3  cut-off the storage device A k1 .

A convector heater element for a tank comprises an upright, closed annular hollow chamber 10 having inlet and outlet ports 15, 16 for connection to a supply of heatable liquid medium, baffle means overlying the area defined by the inner wall 12 of the chamber and comprising a plate 17 level with the top of the annular chamber and having an aperture 18 therein, and a wall 19 extending downwardly from the aperture, a plurality of apertures 21 provided in and adjacent the top of the inner wall to allow communication between the chamber and the de- 'fined area, and a vent pipe 20 projecting up through the top of the chamber and reflexively bent so that its outer end terminates adjacent the upper surface of the baffle means, the inner end of the pipe within the chamber being on a level lower than the apertures 21. The hot water tank in which the chamber 10 is located is initially filled with water which overflows through the apertures 21 into the chamber to fill the boiler and the pipes connecting the boiler to the chamber. Air trapped in the chamber 10 and under the plate 17 between the wall 12 and the flange 19 and also in the pipe 20 serves to separate the water in the chamber, boiler and connecting pipes, whereby the water in the tank is not contaminated by corrosion of the boiler, chamber and connecting pipes.

Abstract: 1295154 Valves EATON CORP 22 June 1970 [8 July 1969] 30169/70 Heading F2V A flow-controlling arrangement, which is designed to operate a motor 35 and to prevent outflow from such motor in the event of the supply pump 9 failing, comprises a spool valve member 12 which is biased by a spring arrangement 43-49 to the shown neutral position in which it isolates the motor, and a pressureregulating valve member 14 which is biased by a spring 6 to the position shown wherein the spool member is isolated from the pump. Upon actuating the pump, valve member 14 is forced by the pumped fluid against its spring such that communication is established between the pump 9 and the spool fluid-supplying passage 17, the passage 17 branching into two parts 18 and 19. Upon moving the spool to the right, as seen in the drawing, the motor piston end is supplied with pressurized fluid from passage 18 and through spool grooves 38a, 37a and passage 34a, whilst the motor rod end is exhausted via passage 34, spool grooves 38, 37 and passage 36. Simultaneously a spool transverse passage 42a communicates with passage 34a and so the spool-interior bore 39a is pressurized with the result that a ball valve member 50 is seated against a similar second spool passage 39; in consequence, a balancing chamber 24 behind valve 14 is also pressurized. Accordingly, and for a given setting of the spool 12, fluctuations in the inlet supply act upon opposed sides of member 14 and so position member 14 such that the supply to passage 17 is maintained constant. In the event of the pump 9 failing, valve member 14 is automatically moved by spring 6 to the position shown wherein reverse flow in passage 17 is prevented. Fig. 2 (not shown) depicts a modified, manually-operable spool valve wherein the passages which lead to the balancing chamber 24 are formed entirely in the body of the valve arrangement.

With no load on the belt voltage U representing tare weight is fed via triple throw switch 40 set at station II to an integrating motor 23 as also is voltage U H  via switch 30 and the sum voltage U 3  is integrated over a given number of belt rotations and displayed by a mechanical counter 24. The switches are then set to station III so that only the voltage U H  is integrated for a given number of belt rotations to obtain a second reading on the counter. The second reading should then be in the same ratio to the first as the ratio of the numbers of belt rotations for the two readings. If not, the wiper 21 is adjusted and the process is repeated until the ratios are equal when tare weight compensation has been effected. To complete the calibration of the machine a weight of known magnitude is weighed and the resultant voltage output to the integrating device is determined,

The tubes of each bundle are located by transverse grids 41 interconnected by tie-bars 40 fixed to the grids 41 so as to allow for thermal expansion of the tubes 9. The grids each comprise a series of zig-zag members 45 attached by straight strips 46 to a plate 42. Tubular sleeves 40 extend between adjacent grids 41 to form the shroud 16, each sleeve 40 being welded to its respective upper grid 41 and being free to slide over a flange on the plate 42 of the respective lower grid 41 to accommodate thermal expansion of the tubes.

Hot liquid sodium enters the heat exchanger at the bottom and passes up through an inlet manifold 15, 32 to a header 20 which feeds liquid sodium to each shroud at the outlet end of the tubes 9. The sodium flows through the shrouds to the inlet ends of the tubes 9 and then enters the shell 1 and finally exits through outlets 61. A by-pass arrangement may be provided to ensure circulation through the shell. The top part of the shell 3 including the inlet and outlet headers 4, 5, the tube bundles 8, the shrouds 16, the sodium inlet manifold 15 and header 20 are all supported on a strong back plate 12 so that they may be removed from the shell for servicing. Insulation is provided in the shrouds 16, the inlet manifold 15 and header 20 and in thermal sleeves 29. Bellows are provided in the thermal sleeves 29 and the ducts 55 to permit expansion of the tubes 9. In another embodiment, Fig. 9, not shown, the tube bundles extend through a lower tube plate to an upper tube plate in each head, the tube plates enclosing a space filled with argon which is monitored to detect leakage of sodium or water. Inspection covers are provided surrounding each space and at the tops of the headers to give access to the tube plates.
