Title: Improvements in and relating to temperature responsive control circuits
IPC: G05D23/24
Filed: 1952-04-10
Abstract: 705,884. Protective cut-out arrangements. BRITISH THOMSON-HOUSTON CO., Ltd. April 10, 1952 [April 11, 1951], No. 9253/52. Class 38(5) [Also in Group XXXV] In a temperature responsive heater control circuit, as for an electric blanket 4, and such as disclosed in Specification 696,369, [Group XXXV], chattering of the relay 10 due to the operator jamming in the closed position the 'On' switch 19 under conditions of over-temperature when the relay is otherwise de-energized, is prevented by connecting the current limiting resistor 20 and the contacts 9 of the relay in series with one side of the supply and the impedance bridge on a whole, and by connecting the On' switch 19 across such resistor 20 and contacts 9. The control circuit comprises the impedance bridge of which two arms consist of potential divider resistors 15, 16, and the other two of a series, resonant. circuit comprising a reactor 18, a capacitor 17, and the blanket signal wire 3. Separated from the wire 3 by a layer of material, e.g. nylon, which is non-conductive within one temperature range, but conductive at a predetermined higher temperature range is the blanket heater wire 1 which is connected, through an ampient temperature responsive variable cycling switch 8 and the relay contacts 9 across the supply. Depression of the `On' button 19 connects the bridge directly to the supply whereupon the series resonant circuit raises the voltage across the bridge to energize relay coil 14 which closes its contacts 9 to make the heater wire circuit. The circuit is deenergized by the relay falling out due to a disturbance of the resonant circuit, either manually by closing 'Off' switch 23 to shunt the wire 3 and capacitor 17 or automatically in response to overheat condition, by conduction between wires 1 and 3.

Abstract: 678,828. Casting-machines. HERBERT, Ltd., A. April 11, 1951 [April 17, 1950], No. 9324/50. Class 83 (i). Metal-pouring.-A device for delivering any desired volume of molten metal to the injection cylinder of a die-casting machine of the " cold chamber " type comprises a gas-heated melting pot having a delivery pipe terminating in a mechanically-operated valve, the pipe and valve being kept hot by flue gases. The gas-heated pot 11 is lined in known manner to prevent reaction with molten light alloy. The pipe 14 is of stainless steel and slopes slightly towards the pot so as to drain into it when the pot is emptied. The pipe and its terminal valve 25, Fig. 2, are arranged in the flue 16. The valve 25 is mounted on a lever 26 pivoted at 27 and operated by a pivoted pneumatic cylinder 30. When the button of an electronic control (not shown), is pressed, compressed air is admitted to the cylinder 30 for a predetermined time and thus allows the desired volume of molten metal to flow through the pipe 14 valve 25 and delivery pipe 34 to the injection cylinder 35 of the casting-machine. This is then operated by the control device in timed sequence. When casting ordinary aluminium alloy the temperature in the pot should be between 650-720‹ C. In a modification the valve is opened by hydraulic or electric power. A separate heater may be used for the pipe 34.

Abstract: 1,157,777. Harvesting machines. ALLIS-CHALMERS MFG. CO. 27 Feb., 1968 [6 March, 1967], No. 9455/68. Heading A1F. A harvester header for edible beans and the like, to facilitate removal of material such as dirt and stones before the crop is threshed, thereby preventing damage to the threshing mechanism, comprises a material feeder mechanism consisting of pairs of tines slidably mounted together, each tine being driven by a crank. The two crank arms driving a pair of tines are of different lengths so that the tines move relative to each other, tearing the crop material and releasing entrapped foreign matter. The crop is received by a rotatable pickup device 6 having pickup fingers 7 movable between stripper members 8, then passes over floor 11 and transversely spaced rods 12, attached to floor 11 and supported by support 17. A disappearing finger feed 18 then feeds the crop into a threshing cylinder. The material feeder mechanism 26 above floor 11 and rods 12 comprises a forward crankshaft 27, provided with three bearing members 37, 38 and 39 mounted on crank pins 33, 34 and 35. The forward portions of the upper tine bars 41, 42 and 43 are rigidly attached to members 37, 38 and 39, whilst the forward positions of lower tine bars 47, 48 and 49 are slidably mounted in these members. A rear crankshaft 52 is also provided with crank pins 53, 54 and 56, having bearing members 57, 58 and 59 thereon. The rear portion of the upper tine bars are slidably mounted in these members, whilst the rear portions of the lower tine bars are rigidly attached to the members. The rear crank pins are longer than the forward ones and, as they rotate, at the same speed, there is relative telescopic movement of each of the three pairs of tine bars 41 and 47, 42 and 48, 43 and 49. Hence crop material is torn apart by tines 46 and 51 carried on the pairs of tine bars, Figs. 6, 7 and 8 (not shown) A vine hold-down device 63 comprising a series of rods 68 mounted on a tube pivotally mounted on supports 64 and 66 holds the crop in contact with the tines after it has been raised by the pick-up fingers. A conveyer 72 mounted below floor 11 and rods 12 comprises laterally extending members 79 connected to chains 78. Material which drops from the vines as they are torn by the tines falls and some is carried by the conveyer on longitudinal rods 82 and falls off the end. Other material falls through the rods 82 to the lower part and may fall through a perforated floor 83 or be carried by the conveyer to the feeder 18 and into the threshing mechanism.

Filed: 1975-03-10
Abstract: 1506170 Fluidized-bed reduction of iron ore STORA KOPPARBERGS BERGSLAGS AB 10 March 1975 [8 March 1974] 9919/75 Heading C7D [Also in Division F4]  Pulverized iron oxide material, e.g. a concentrate, is mixed with solid (and optionally liquid) carbonaceous material and an 02-containing gas in a vertically elongated fluidized bed reactor wherein a mixture of gas and solid is removed from the reactor and separated, with the solids being returned to the reactor. Reactor 1 is charged with iron oxide material through conduit 6, carbonaceous material through inlet 7 and 02-containing gas, e.g. air, through nozzles 8. Iron oxide material is passed through inlet 20 to cyclone 19 where it is heated by off-gases from the reactor 1 and passes to conduit 6 after separation from the gases in cyclones 21, 22. Off-gases from the reactor have entrained dust separated out in cyclone 5 and returned to the reactor through conduit 6. The dust-free gas from cyclones 5, 19, 21, 22 passes to a heat exchanger 25, to scrubbers 27 where CO 2  and H 2 O are removed, and to compressor 29, the bulk of the gas then flowing to gas distributor 9 for fluidization and reduction purposes. The particles of reduced oxide, discharged at 10, are cooled to below the Curie temperature in cooler 11 and magnetically separated at 12 into an iron fraction 13 and a coke fraction 14. The O 2 -containing gas from 15 is pre-heated by passing it through the cooler 11. The cooler 11 and separator 12 operate on the fluidized bed principle using cleaned gas from compressor 29. Some of the coke fraction 14 may be recycled to inlet 20, and the remainder of fraction 14, together with some of the exhaust 34 from cyclone 5 may be used as a fuel in a power station. The solid carbonaceous material is preferably introduced with neutral and/or reducing gas Ie.g. part of the flow from compressor 29), or if of low volatile content, e.g. anthracite, with air Oil may also be introduced to the central part 3, e.g. by spraying.
