Abstract: 1,269,128. Central heating systems. ZENTRA ALBERT BURKLE K.G. 13 Nov., 1969 [13 Nov., 1968], No. 55750/69. Heading F4U. [Also in Division F2] In a heating system in which a heat transfer fluid (e.g. water) circulates from a heat source (e.g. a boiler) to heat transmitting means (e.g. radiators 4) and back to the heat source, arrangement is made to ensure a return flow of adequate temperature to the boiler in order to minimize corrosion therein by condensate from the boiler flue gases. The arrangement comprises mixing in a device 7 return water from the radiators 4 with primary flow water from the boiler such that the proportion of return flow water so mixed, at least over a range of temperature, decreases as its temperature falls, the arrangement also comprising a mixing manually or ambient-temperature actuated device 3 in which return flow from the radiators is mixed with boiler water flowing to the radiators. The two mixing devices may be combined in a single  4-way valve unit (Figs. 3 and 4 or Fig. 5), or as shown, the two devices may be separate. The system shown also includes a circulating pump 19.  Fig. 2 shows one form of the device 7 having an inlet duct 11 for relatively cold water from the radiators and an inlet 13 for hot water from the boiler. The mixture which passes out through an outlet duct 14 is controlled by a bimetallic throttling element 17 which when the radiator return water is at its hottest assumes the position indicated at 23 and when at its coldest e.g. on starting up, assumes the position indicated at 21, so that the boiler return flow through the outlet 14 is always relatively hot. On the side facing the boiler primary flow, the bimetallic strip 17 may have a heat insulating 20 coating of plastics material so that it tends to assume the temperature of the radiator return flow. Fig. 3 shows a unit incorporating both the devices 3 and 7. A valve cock 41 (corresponding to device 3) operable either manually or automatically in accordance with ambient temperature, controls the proportions of boiler water (inlet 36) and radiator return water (inlet 38) passing through outlet 37 to the radiators; and the bimetallic throttle member 53 mounted either on a fixed bar 49 or on the partition wall 35 of the cock 41 (Fig. 5), and corresponding to the device 7, controls the proportions of boiler water (inlet 36) and radiator return water (inlet 38) being returned to the boiler through outlet 39.

Abstract: 1285615 Generators and pumps operating by electromagnetic interaction with fluids COMPAGNIE ELECTRO-MECANIQUE 21 Nov 1969 [28 Nov 1968] 57208/69 Heading H2A In an MHD process, for the generation of electricity or compression of a gas or vapour, where an electrically conductive liquid flows in a closed circuit path within a travelling multipole magnetic field, the speed of the liquid being greater than that of the field in one region of the circuit and less than that of the field in a second region, the liquid is emulsified with a gas or vapour in one of the regions, the gas or vapour being injected into and separated from the liquid in regions of the circuit intermediate the first and second regions. In the generator shown, gas or vapour is introduced into the liquid in an emulsifier 1 and the composite fluid expands in a duct 2 moving at a speed greater than that of the travelling field produced by the winding 8 and so generating A.C. in winding X. The gas or vapour is then removed from the liquid in a separator 5 and the liquid pressure restored to its original value in a duct 6, the liquid velocity being less than that of the field in this region. The windings are located in slots in a two part magnetic core D1, D2, Fig. 2, each of the two parts forming a ring covering also the emulsifier and separator regions. The winding may extend into the separator and emulsifier regions where the fluid velocity equals that of the field. The side walls 3, 4, of the ducts are conductive, extend into the emulsifier and separator regions and are short-circuited with one another. The ducts 2 and 6 are respectively divergent and convergent. To maintain the air gap between the two parts of the core constant, two closed fluid circuits may be placed between the cores, one circuit being rotated through 180 degrees with respect to the other so that the divergent duct of one is superimposed on the convergent duct of the other, Fig. 4 (not shown). It is stated that the apparatus may be arranged to have a cylindrical or conical air gap as opposed to the flat air gap shown.

Abstract: 1,207,379. Valves. OLEOMAT. 22 Dec., 1967 [27 Dec., 1966], No. 58469/67. Heading F2V. [Also in Division F1] An hydraulic system comprises two separate circuits 4, 5, each supplied by a respective pump 2, 3 driven by a common heat engine 1, the pressure in circuit 4 being controlled by a valve 14 and that in circuit 5 by a valve 15, the loading of the valves being varied as a function of the hydraulic pressure existing in the other circuit. The valves 14, 15 are identical and each comprises a valve member 18 which controls connection between its circuit and a chamber 24a connected to a sump 26. Each valve member 18 is loaded by a spring 22 which bears against an adjustably spring-loaded piston 21, the position of which is determined by the pressure in a chamber 24b connected by a line 27 or 28 to the other circuit 5 or 4. When a circuit, say 5, is connected to the sump 26 by a distributer 10 controlling devices 11-13, the valve 17 is fully loaded, whereby high pressure is available in circuit 4 for operating devices 7-9 controlled by a distributer 6. If the circuit 5 commences to take pressure, the loading on the valves 14, 15 is reduced by the pressure in lines 27, 28 and hence stalling of the engine 1 is prevented. The piston 21 of one circuit may be actuated by mechanical, electrical or pneumatic means operable in response to the hydraulic pressure in the other circuit.

Abstract: 1425630 Valves E P SCRAGG 18 Dec 1973 [9 Jan 1973 25 May 1973] 58664/73 Heading F2V In a fluid flow control valve, downward movement of rod 48, Fig. 1, in direction of arrow "A" causes the rod to pivot about flexible diaphragm 36 and raise valve 24 off its seating. The rod and diaphragm are of integral construction and may be reinforced at 48 and C. Partition 18 defining the valve seating may be thin so as to flex on sudden valve closure to prevent water hammer. Alternatively, the seating may be formed by a plate held against the partition by a spring, Fig. 2 (not shown). The rod may be eccentrically connected to a diaphragm which is rotatable within the valve housing so that by rotating the diaphragm the rod is effectively raised and lowered to operate the valve, Fig. 1A (not shown). Stops are provided to limit the rotation of the diaphragm to 180 or 360 degrees. The valve may be included in a shower head having the rose (70), Fig. 3 (not shown), at its lower end. The valve head 78, Fig. 5, comprises a thin frusto-conical skirt 78.1 which is deformable by inlet pressure to compensate for any ovality in the seat. The valve head may be associated with an additional valve element 100 which is opened by a pin 98 slightly after head 78 to thereby reduce the opening force that would be required with a single head of the size of element 100. Fig. 6 shows the valve incorporated in a compressed air gun having a guard 108 and lever 110. Upward movement of the lever causes slight forward movement of the minor part of the lever and hence pivots the valve stem 84 about its diaphragm to open a valve 104.

Abstract: 1313679 Fatty acid separation HENKEL & CIE GmbH 16 Dec 1970 [31 Dec 1969 20 June 1970] 59622/70 Heading C2C Fatty acid mixtures containing 0À8 to 15% by weight of organic impurities are separated into components of different melting points by converting to a dispersion of liquid and solid fatty acid particles in aqueous wetting agent solution, separating into a lighter and denser phase being the liquid and solid fatty acid particles respectively, separating the solid fatty acid particles from the aqueous solution, removing a part of the aqueous wetting agent from the circuit and replacing the same by water or by aqueous solutions containing wetting agent and/or electrolyte. The amount of wetting agent solution to be removed is between 10 and 70% by weight of solution depending on the amount of impurity. The process may be used for the separation of distilled tallow fatty acids, cottonseed oil fatty acids, palm kernel fatty acids, fish oil fatty acids, and undistilled fatty acids from the fission of beef tallow. The starting mixtures are cooled from the molten state to the separation temperature, and dispersed in the solution of wetting agent, e.g. soaps, and anionic or non-ionic water soluble substances which may contain dissolved non-surface active electrolytes, separated by a centrifuge and the wetting agent solution containing the solid is replaced in part at one or several points. Apparatus is described showing the centrifugal separation of the oil and solid particles, followed by further separation and part removal of the wetting agent solution. A modification in which the oily lighter fraction is further dispersed in aqueous wetting agent solution and the resulting solid suspension worked up with that from the first stage, and a modification in which the suspension of solid fractions is heated and separated by aqueous wetting agent solution are also described.

Abstract: 1,196,848. Control of D.C. motors. SPERRY RAND CORP. 16 Dec., 1968 [17 Jan., 1968], No. 59733/68. Heading H2J. [Also in Division H1] An electric motor 24 is prepared for operation in a downward direction when a relay is energized to close contacts D2 in series with a rectifier SCR. The latter is not rendered conductive, however, until contacts D-3 of the relay are closed with some delay whereby the armature current does not pass through the contact D2 until they are firmly engaged. The contacts D2, D3, are opened in reverse order when the relay is de-energized. A capacitor C1X is charged initially through contacts D2, diode D2X, and resistors B5X-R2X, until contacts D3 close to complete a direct charging circuit. A diac DC1X then breaks down to trigger the rectifier SCR for the remainder of the half-cycle involved, after which the capacitor is discharged through diode D1X, resistor R1X, and field winding 42. A network comprising resistor R6X and capcitor C2X serves to bias the breakdown voltage of diac DC1X, this network being subjected to the line voltage through a varistor V1X. If the line voltage increases, capacitor C1X is charged at a greater rate but will be required to reach a higher voltage before triggering occurs. Slow operation is provided by shunting the armature by a swamping resistor R6 and connecting resistors R4X, R5X, into the timing circuit. A slow starting relay has a coil across the armature and delayed contacts which close to short-circuit the resistor R2X, Figs. 4, 5 (not shown).
