Title: Improvements in fluid heating systems
IPC: F22B3/04
Filed: 1956-11-21
Abstract: 807,288. Automatic temperature control systems. FOSTER WHEELER Ltd. Nov. 21, 1956 [Nov. 21, 1955], No. 35596/56. Class 38 (4). [Also in Groups XIII and XXVI] In a heat exchanger 60 in which air flowing through tubes 73 to an outlet 76 is heated by a heat transfer liquid such as sodium potassium surrounding the tubes, the air temperature at the outlet 76 is maintained at a predetermined value by adjusting the liquid level of the heat transfer liquid in the heat exchanger. This adjustment is effected by regulating the speed and direction of a pump 115 which acts to either supply or withdraw the heat transfer liquid to or from the heat exchanger as necessary. If e.g. the air temperature in conduit 76 is below the desired value an air temperature sensing element 88 in the conduit 76 actuates a valve 91 in a pneumatic control line 92 to vary the pressure downstream of the valve and hence actuate a bellows 93 movement of which displaces one end of a link 95 upwardly thereby moving a core 103 away from a secondary winding 108 of a transformer 104. Consequently a signal of one phase is induced in the secondary windings and is then amplified by amplifier 109 and fed to variable-phase winding 111 whereby a motor 112 driving the pump 115 is rotated in a direction to feed heat transfer liquid from a surge tank 81 into the heat exchanger shell 65. The consequent rise in the liquid level in the heat exchanger shell changes the relative pressures in bellows 98, 99 (communicating respectively with the shell space above and below the liquid level therein), and thus causes movement of link 96 in a clockwise direction, which movement is imparted to link 95 as a counterclockwise motion tending to displace core 103 to a central position between the transformer windings 107, 108 so that the signals from the transformer windings cancel out and therefore motor 112 and pump 115 are stopped. Conversely when the air temperature in conduit 76 is above the desired value the temperature sensing element 88 acts to move the core 103 away from the secondary winding 107 of the transformer thereby rotating the pump 115 in the opposite direction to withdraw heat transfer liquid from the shell 65 until such time as the pump is stopped by restoration of the balance of pressures in bellows 98, 99. The heat transfer liquid in heat exchanger 60 receives its heat from further tubes 63 in which liquid sodium circulates, the heating circuit including a sodium heater 12 and a unidirectional variable-speed pump 124, the speed of the pump being varied through a control device 122 regulated by a temperature sensing element 116 in the sodium circuit located at the sodium outlet from the tubes 63 of the heat exchanger. Fuel supply through conduit 45 to the heater 12 is regulated in accordance with the temperature of the sodium flowing from the heater to the tubes 63.

Title: Improvements in or relating to fluid supply means for hydraulic presses and the like
Inventor: TAYLOR NORMAN CHARLES FRANK
IPC: B30B15/16
Filed: 1960-10-20
Abstract: 918,259. Hydraulic presses. LANGDALE ENGINEERING CO. Ltd. Jan. 17, 1962 [Oct. 20, 1960], No. 35917/60. Class 69 (2). A fluid supply system for an hydraulic press or the like required to make a long rapid approach movement at low pressure followed by a short slow movement at high pressure comprises a displacement unit A consisting of a small bore cylinder 1 in tandem with a larger bore cylinder 3, a connection 9 in the cylinder 1 to apply high pressure from a source 8 to one end of a small piston 2 which extends into the larger cylinder to effect movement of a large piston 4 against a spring 5, a non-return inlet 6, 7 in the end of the larger cylinder remote from the small cylinder for admitting operating fluid when the piston 4 is free to be moved by the spring, a sequence valve B having an inlet 10 for connection to the same high pressure source 8 and an outlet 11 leading to the cylinder 21 of the press, and an outlet 13 and non-return valve D connecting the larger cylinder to the outlet 11 from the sequence valve to the press cylinder. The sequence valve B has a spool 23 urged by a spring 26 to a position closing the outlet 11 so that the pressure from the source 8 acts initially only on the small piston 2 which moves the larger piston 4 against the spring 5 to displace fluid through the outlet 13, non-return valve D, a control valve C and lines 19, 20 to the upper end of the press cylinder, the fluid from the lower end of the cylinder passing to an exhaust 28. When the ram encounters resistance, the increase in pressure in the press cylinder 21 acts through a passage 25 on to the end of the spool 23 of the sequence valve B which is moved against the spring 26 to connect the source 8 directly to the press cylinder, the non-return valve D preventing the high pressure fluid entering the cylinder 3. At the completion of the pressing operation, the control valve C can be operated to reverse the connections to the press cylinder so as to raise the ram, but the actual movement of the valve is restricted by the high pressure in the upper end of the press cylinder acting through a line 29 on the control valve so that the exhaust 28 is only partially open, the fluid from the upper end of the cylinder passing through the partially-open exhaust until such time as the pressure drops sufficiently to permit the full movement of the valve to be effected. At the same time a by-pass 26, which normally unloads the source 8 when the control valve is in its neutral position, is opened to relieve the piston 2 and enable the spring 5 to return the piston 4 and fluid from a tank mounted on the upper surface 16 of the displacement unit to pass through a port 6 and non-return valve 7 to recharge the cylinder 3. A relief valve E may be provided which together with the sequence valve B and non- return valve D may be mounted in the displacement unit, the ports being interconnected by hollow bars secured to the units.

Title: Dehydrating apparatus
IPC: C04B11/028
Filed: 1958-07-16
Abstract: <PICT:0897927/III/1> <PICT:0897927/III/2> Dehydrating apparatus comprises a drum having an axial tube through which heating gases are passed and connected to at least one other tube formed in the wall of the drum such that part is exposed inwardly and part exposed outwardly of the drum.  As shown in Figs. 1 and 2 a drum 6 is supported by, and rotates about, an axial pipe 21 which rests on rollers 5.  Inside the drum the tube 21 carries and accordion-like arrangement of annular dished members 26 peripherally joined at 28 to form a series of chambers communicating with the interior of pipe 21 through perforations 25.  A gas burner 22 delivers a blast of hot combustion products into pipe 21 from the left-hand side and these gases pass through perforations 25 into the chambers 33 formed by the annular dished members 26.  The chambers 33 communicate with tubes 8 (Fig. 2) formed in the walls 7 of the drum by means of pipes 30. Tubes 8 are provided with exhaust passages 31 having terminal elbows 32, whereby the hot combustion gases from chamber 33 pass through connections 30 into tube 8 and out through exhausts 31 in contact with the exterior of drum 6.  Gypsum is fed to the drum through removable closures such as 11 and the steam formed by dehydration is vented through valves 13.  As shown in Fig. 2 the valve 13 is operated by a lever 16 carrying a roller 18.  The latter abuts a valve operating cam 19 which is manually adjustable so as to release steam pressure as desired when the drum rotates.  In operation for the dehydration of gypsum, gypsum pieces having a maximum dimension of one inch are fed to the drum in an amount sufficient to permit relative movement between the pieces of gypsum on rotation.  The steam tight closures 11 are sealed and the drum rotated.  The pressure rises to about 35 p.s.i.g. as the gypsum becomes heated and thereafter rises to about 40 p.s.i.g. as dehydration commences.  The cam 19 is thereupon adjusted to release the steam pressure and as dehydration proceeds the valves 13 are opened progressively wider until at the end the pressure has dropped to atmospheric.  The drum may be preheated before introducing gypsum to a temperature of about 300 DEG  F.  During dehydration the temperature remains at about 250 DEG  F. and may be raised to about 270 DEG  F. at the end of the operation. Specifications 866,126, 897,924, 897,925 and 897,926 also are referred to.

The washer-extractor is supported by stanchions 54 fixed to a base 57 (Fig. 3) and is suspended thereon as shown in Fig. 5 the weight of the washer being supported by an adjustable bolt 97 held by a plate 94a on spring 95a. A snubbing pad 73 which is formed of brake shoe material or the like is held between plates 77 and 83 and causes damping of the oscillations in the springs due to vibration of the load on the washer-extractor, the amount of damping being adjustable by bolts 79. Several of the bolts 97 are provided on each stanchion and are used to level the washer-extractor independently of the base plate and stanchions. Radially disposed weights are fixed in the cabinet and are heavy enough to ensure that any non uniform loading in the washer will not cause excessive vibration of the cabinet. Washing powder or the like is supplied from hoppers 120 (Fig. 6 not shown) which are normally held by support bar 116 in the upright position. At a predetermined signal from a timer device (not shown) a piston operated contact 124 lifts a lever 119 and empties the hopper through an opening 23 into the washing drum. When in its inverted position (shown in broken lines 120 in Fig. 6) water from the rotating drum can enter the hopper 120 and wash out all the remaining soap powder, but this water does not enter any of the drums still remaining in their upright positions.
