Title: Improvements in or relating to a blank-feeding mechanism
IPC: B21H9/02
Filed: 1953-07-30
Abstract: 740,019. Shoots and hoppers ; endless belt conveyers. WATERBURY FARREL FOUNDRY & MACHINE CO. July 30, 1953 [Sept. 3, 1952], No. 21157/53. Class 78 (1). A feeding mechanism for blanks which travel along a sheet comprising spaced supporting members consists of a rotatable element adapted to engage the top of the blank heads and position the blanks on the shoot and a clearing member disposed above the shoot and adapted to rotate vertically to clear improperly placed blanks from the shoot. Blanks are fed from a hopper 16 to a shoot 17 between rollers 18, 19 leading to a guide channel comprising spaced members 10, 11. The blanks are conveyed along the channel by a conveyer belt 14, one edge of which is at the upper level of the member 11. A cover member 20 is positioned above the channel. The blanks pass between a pair of toothed wheels 33, 34 positioned to clear the heads of properly positioned blanks in the channel, and spaced apart the diameter of a head so that improperly positioned blanks are thrown out. A second clearing wheel is mounted on the same shaft 32 as the wheels 33, 34 and is in two parts 35, 36 having a central groove to accommodate the cover and having a smaller diameter to throw off any blanks riding on top of another blank. Since the blanks may overlap in the channel, they pass below another wheel 45 rotating in the opposite direction to the other wheel to space the blanks. The wheel mounted on a shaft 44 comprises two parts 45, 46, with a central slot for the cover. The shaft 32 is pivotally mounted in a sleeve 25 pivoted upon a pin 27 supported by arms 27 of a bracket. The sleeve is supported by an adjusting screw 30 which bears upon the bracket. The shaft 44 is similarly mounted on the pin 27 and adjusted by a screw 43. The shafts 32 and 44 have gears 48, 49 in mesh, the shaft 44 being driven by a belt 51 passing round a pulley 52 on the driven shaft of the pulley 15 round which the conveyer belt 14 passes. The blanks pass to an indexing wheel 12 which presents them to a processing machine.

Title: Device for the preparation of a dosed mixture
IPC: A01C23/04
Filed: 1962-06-01
Abstract: 959,863. Spray-producers. G. ROTVAND. June 1, 1962 [April 11, 1962], No. 21200/62. Heading B2F. A device for spraying a mixture of active liquid and water comprises (i) a Venturi tube connectible at one end with a source of water under pressure and at the other end with a spray nozzle or equivalent, (ii) a rigid container, (iii) a flexible container housed in the rigid container ; said containers communicating with the Venturi tube in such a manner that water under pressure is by-passed from the upstream end of the Venturi tube, either into the rigid container to contact the flexible container or into the flexible container to expand it, whereby liquid is forced into the throat of the Venturi tube. Liquid, e.g. fungicide, which is to be diluted with water is enclosed in a container 12, which is also partly occupied by a bladder 11. Mounted on the container is a nozzle 1 with a Venturi bore, the inlet 3 being connected to a water main or other source of water pressure and the outlet 4 to a hose leading to a spray nozzle or atomizer. A tube 6 leads through the cover 13 of the container to the restriction 2 of the Venturi bore for access thereto of the liquid. A tube 10 connects the bladder 11 with the inlet bore 3, passing through a valve 9. The dilution is adjustable by the valve 9, by which a controlled quantity of water enters the bladder 11 which, expanding, forces liquid from the container 12 which is drawn out through the tube 6 by the Venturi effect of the main water stream, with the result that the liquid mixes with the water and leaves at 4. The arrangement may be incorporated in a unit body 14, Fig. 3, having spigots through which pass, respectively, a bore 5 leading to the constriction 2 and a bore 10 leading to a plain bore 19 parallel to the Venturi bore. An oblique bore 20 connects the bore 19 with the upstream part 3 of the Venturi bore. The spigot 18 fits the outlet of a container (not shown) and on the spigot in which is the bore 5 a bladder (not shown) is fitted. The supply of water to the bladder may be regulated by a sliding valve member 21 in the bore 19, shaped as shown in Fig. 8 and and having an extension 25 marked in graduations so that the proportion of water is indicated by the position of the valve member. The device may be adapted, Fig. 9 (not shown) so that the liquid is contained in the bladder and the water in the container, immersing the bladder. The flow through the pipe 8 may be controlled by a butterfly valve. Inversely, the flow may govern the position of a butterfly valve, suitably biased, the position of which may be used as a signal to show when the liquid needs renewal.

Convention date, Oct. 31, 1929. [Class 110 (i).] A centrifugal fan is provided with means for controlling the flow of fluid through the fan, and a byepass which permits the passage of fluid from inlet to outlet round the control means. An induced draught fan connected to a stack has blades 6 on a shaft 4 in a casing with an outlet 10 and an inlet chamber 8 at each end. Control of the flow is obtained by vanes 12 in the inlet chambers ; these vanes can be adjusted to vary the spin velocity of the entering gas. The plate 14 between each inlet chamber 8 and the fan chamber is provided with a byepass opening 16 normally closed by a damper 18 secured to a spindle 24 journalled in bearings 26, 28. A counterweight 34 is adjusted so that the damper swings to its open position when the pressure in the inlet is slightly higher than that in the outlet. Stops 38 on arms 40 limit the movement of the damper. During normal operation the damper remains closed ; with a light load, the vanes 12 are adjusted and may be entirely closed so that the entering gas passes through the leakage spaces. With still lighter loads the fan is shut down, and if the passage through the vanes 12, whether they be open or shut, is not sufficiently large, the damper 18 will open and gas will pass directly from the inlet 8 to the outlet 10 and the stack. Specification 295,018, [Class 110 (i), Centrifugal and screw fans &c.], is referred to.

Abstract: 728,427. Casting composite articles. GENERAL MOTORS CORPORATION. Aug. 4, 1953 [Aug. 8, 1952], No. 21424/53. Class 83 (1). A method of impregnatnating only selected portions of a porous metal part with a metal of lower melting point than that of the part to be impregnated, comprises placing a predetermined quantity of impregnating metal adjacent the portion of the porous part to be impregnated, selectively heating the impregnating metal and only that portion of the part which is to be impregnated, to a temperature above the melting point of the impregnating metal and below that of the metal of the porous part, while maintaining the remainder of the porous part at a temperature below. the melting point of the impregnating metal, and maintaining said heating for a time sufficient to allow infiltration of the melted impregnating metal into the heated portion of said porous metal part, whereby the impregnating metal only infiltrates into that portion of the porous part which is above the melting point of the impregnating metal. In the preferred arrangement, the parts are heated by induction heating, but flame heating may be used. The impregnating metal should not alloy appreciably with the metal of the porous part, and lead and its alloys may be used for bronze, copper-nickel or iron porous parts, and cupreous metals for iron parts. The invention is described with reference to the impregnation of a portion 30 of a compressor rotor 20.
