Title: Improvements in methods and means for maintaining a uniform temperature in incubators and other enclosed structures
IPC: A01K41/02
Filed: 1932-05-30
Abstract: 403,403. Hatching-appliances. SCHAEFER, C. A., Springfield, Ohio, U.S.A. May 30, 1932, No. 15346. Convention date, April 13. [Class 5 (ii).] A method of maintaining a uniform temperature in an incubator or other enclosed structure by the thermostatic regulation of electric circuits comprises circulating an air current within the structure and controlling heater and damper circuits by means of two co-operating thermostats of different degrees of sensitiveness of which the more sensitive acts through a comparatively small temperature range included within the wider temperature range of the less sensitive thermostat, in such a way that the less sensitive thermostat acts at the end points of its range to transfer the control from the heater circuit to the damper circuit and the more sensitive thermostat acts at the end points of its range to open or close the heater or damper circuit. An incubator comprises mesh bottom trays 7 stacked on either side of a central corridor 8, air being circulated over and through the trays by an electrically driven fan 11 supported in a vertical partition 12, provided with an opening 13 through which air is forced, the air passing through the passages 13a, 14 and thence horizontally through the trays. Horizontal division plates 7a prevent vertical movement of the air. A heating element 16 is mounted across the face of the fan. Air is admitted to the incubator through a duct 19 controlled by a damper 20 and discharged through an aperture 23 controlled by a damper 24. The dampers 20, 23 are connected together and to an operating lever 51 by link mechanism 28-31, the lever 51 being operated by a centrifugal device 42 intermittently driven by an electric motor 35 and including an indicator 57. The motor 35 and heaters 16 are controlled by thermostats 17, 18 of which the former is the more sensitive. The thermostats 17, 18 operate switches 75, 76 controlling relays 66, 67, Fig. 4, whereby switches 70, 71 are caused to bridge gaps 72, 73 in the heater circuit or gaps 78, 78<1> in the motor circuit. The less sensitive thermostat 18 by operation of the switch 71 transfers the heat control to or from the heater circuit 77 from or to the motor circuit 79 and the more sensitive thermostat 17 by operation of the switch 70 opens or closes the appropriate circuit.

Patent GB-461059-A (GB)
Title: Improvements in or relating to the preparation of aluminium oxide
IPC: C01F7/02
Filed: 1936-06-02
Abstract: Raw materials containing besides aluminium oxide mainly silica and/or titanium oxide, for instance bauxite, clays or laterites, are melted with lead oxide, and the melt slowly cooled, whereafter the crystals of alumina are separated from the mass as by gravity concentration or flotation.  The lead oxide must be present in sufficient amount to form the compound PbO.SiO2 with any silica present and the compound PbO.TiO2 with titanium, and advantageously enough may be used to form the compounds 2PbO.SiO2 and 2PbO.TiO2.  The aluminium oxide content of the melt should be less than 35 per cent, and may advantageously be reduced to 10--20 per cent as by adding further lead oxide or lead silicate to the charge.  The melting point and viscosity of the charge may be lowered by adding sulphides such as PbS or Cu2S or lead chloride, and the alumina may be segregated into the upper portion of the melt by initial slow cooling to separate the alumina from the melt followed by rapid heating.  The melt may also be centrifuged to assist separation of the grains of alumina.  By treating the cooled and crushed melt with acid, a lead salt is obtained from which lead oxide for re-use may be recovered, or the lead oxide may be regenerated by first forming metallic lead and subsequently oxidizing it.  By treating the cooled and crushed melt with acetic acid, a mixture of aluminium oxide, silica, and lead acetate is obtained, and by melting the lead acetate, alumina sinks to the bottom and silica rises to the top of the melt, whereby separation may be effected. The separation of titanium oxide and silica obtained in admixture by acid treatment of the cooled mass may be similarly effected. If the initial material, for instance red bauxite, contains iron, this should be removed, as by reduction to FeO followed by leaching with acid, by reduction to Fe3O4 followed by magnetic separation, or by chlorination with chlorine.  Titanium may also be removed if desired, by treatment with chlorine.

Title: Improved means of coupling rolling stock
IPC: B61G3/04
Filed: 1928-05-25
Abstract: 291,730. Blair, A. W. June 6, 1927, [Convention date]. Couplings, non-automatic, convertible to automatic.-In replacing a system of non-automatic hook couplings of the central buffer type for railway and like vehicles by automatic couplings, the automatic coupler is formed with a recessed head 1, Figs. 15 and 16, which, during the transition period, is adapted to accommodate a false buffing-face 17 which is in turn recessed to receive a coupling-hook 81 from an opposing vehicle, or to accommodate a hook adapted to be received by the opposing vehicle. In the arrangement described, Figs. 15 and 16 illustrate transition stages in replacing a non-automatic coupler of the central buffer and hook type as shown at the left of Fig. 15 by automatic couplings of the knuckle type, Figs. 1 and 2, the latter couplings being further characterized by the provision of a knuckle 5 embracing the coupler-head 1 externally, thus leaving a recess 2, in which the false buffing-face may be disposed, and which is further recessed at 3 to receive the locking-pin 4 for the coupling. In the stage of transition, Fig. 15, the knuckle 5 and locking-pin 4 are removed from the automatic coupler-head, the false buffing face 17 is inserted and retained in position by a pin passing through an extension 16 thereof, and a coupling-pin 20 is passed through holes in the coupler-head and buffing-face 17 to co-operate with the hook 81. In the stage shown in Fig. 16, two of the automatic coupler-heads are connected by a hook 81 pivoted on the pin 20 of one of the heads. When all of the vehicles have been fitted with automatic coupler-heads the false buffing-faces 17 are removed, and the knuckles 5 and locking- pins 4 fitted in position. Couplings, automatic. - In the automatic coupling described the knuckle 5, Figs. 1 and'2, is formed as a yoke pivoted on pins 6 and embracing bosses 8, 8<a> on the coupler-head, while the vertically sliding locking-pin 4, Fig. 11, is formed with locking faces 12, which, in the dropped position of the pin, engage faces 13 on the tails 7, 7a of the knuckle, and with recessed portions 75 which. in the raised position of the pin, allow the tails to swing inwardly for uncoupling purposes. The pin is raised to its upper or non-locking position by a link 21 and supported by a lock-set member 30, Fig. 9, pivoted on a fixed sleeve 22, through which passes a shaft 25 carrying a cam tripping-member 29, the members 29, 30 falling by gravity into the lock-set position shown. When the couplerheads engage and the knuckles 5 are swung round, a projection 73 at the rear end of the upper tail 7 strikes a trigger member 28 causing the shaft 25 and member 29 to rotate, thereby displacing the lock-set member 30 and allowing the locking-pin 4 to drop. The rear portion of the coupler-head is extended to form a draw-bar 36 slidably arranged in association with a drawbar spring.

Title: Device for counting leaves or sheets in a pile or packet
IPC: G06M9/02
Filed: 1951-06-29
Abstract: 688,251. Counting-apparatus. ROSSWALL, A. E. June 29, 1951, No. 15523/51. Class 106 (i). A device for counting leaves or sheets in a pile or packet in which each leaf in turn is sucked on to a suction nozzle from which it is subsequently stripped by a leaf stripper comprises operating mechanism for effecting relative movement between the nozzle and stripper so that the stripper moves the leaf from the suction side of the nozzle, the suction nozzle, the leaf stripper and the operating mechanism being carried on a support which is mounted to tilt about a horizontal shaft to allow for the limited travel of the suction nozzle and leaf stripper in relation to the pile or packet and means being provided for effecting intermittent relative movement between the pile or packet and the support and its associated shaft in the direction of the thickness of the pile or packet. The invention is an improvement in the device disclosed in Specification 557,086. The suction nozzle 1, Figs. 1 and 2, and the leaf stripper 2 are oscillated and rotated respectively in the known manner through linkage from a shaft 3. The complete mechanism is mounted on a platform 14 tiltably suspended from a horizontal shaft 16 by a pair of arms 15. The shaft 16 is mounted in a runner 18 which is vertically movable on posts 19 and which has a base 23 carrying a nut 28 which engages a screwed spindle 27. The platform 14 tends to rock clockwise by gravity so that as the nozzle 1 and stripper 2 are operated they are moved up the pile of sheets by the clockwise tilting of the platform 14 until a lever 20 carried by the platform rocks a lever 21 to close a mercury switch 22. An electric motor 25 then rotates the screwed spindle 27 whereby the runner 18 is raised vertically and the platform 14 returns to its initial slope and the mercury switch 22 is again opened so that the motor 25 stops. The nozzle 1 and stripper 2 therefor climb up the pile of sheets. The actuating device of a counter of the cyclometer type is controlled by the degree of vacuum in the suction nozzle.

Title: Method of heat treating elements and furnace therefor
IPC: C21D1/74
Filed: 1963-04-19
Abstract: A method for heat treating elements in a furnace in which fuel is burned in the furnace chamber, comprises the steps of stopping the furnace fuel supply after a predetermined length of time, and forcing air through porous enclosure means of the furnace chamber to cool the elements rapidly.  The combustion chamber of a suitable furnace comprises a cylindrical, porous, refractory brick wall 36 surrounded by a wire screen or mesh 37.  The furnace bottom 38 is made of refractory material whilst a removable roof 20 rests in an annular sand seal 22.  An outer cylindrical casing 32 is spaced from the inner wall 36 and air from a forced draft fan 18 is blown into this space 44 through duct 50.  Further air is supplied through ducts 16 to twelve burners 12 located in three layers and 90 degrees apart, and pipes 14 supply the gas to be burnt.  In operation, an exhaust hood 26 is swung aside to position the elements 28 within the furnace.  Fuel and air are supplied to the burners 12; the amount of fuel being in excess of that required for combustion.  Further air is then supplied to the space 44 and is maintained at a pressure greater than that in the chamber by the partial closing of damper 56, this causing an air flow through the porous wall 36 and the combustion of the excess fuel on the inner surface thereof.  This air flow through the walls prevents heat flowing outwards and also maintains the walls at a low temperature.  For cooling, the fuel and air supply to the burners is cut off but is still supplied through the walls.  A plate 40 prevents a "cold" spot from developing on the furnace <PICT:0985125/C6-C7/1> bottom 38.  A thermocouple 60 senses the temperature of the furnace and causes a control unit 62 is shut off the fuel and air supply to the burners when required.
