Patent GB-421311-A (GB)
Abstract: 421,311. Grinding-machines ; casting-machines; moulds. MARX, E., 75, Gutleutstrasse, Frankfort-on-Main, Germany. April 14, 1934, No. 11293. Convention date, May 5, 1933. [Class 60] [See also Group XXII] The abrading members 4, Fig. 5, of cylinder honing tools are secured in channel section mountings 3 by binding material, such as molten lead, tin, or alloy, which is forced into the intervening space under sufficiently high pressure to cause it to enter the pores at the surface of the abrading members so as to form a firm connection. Fig. 1 shows one part of a twopart mould used for the operation, and Fig. 5 a section of the mould. The part 1 of the mould contains a recess 5 which receives the base of the channel member 3, and the part 2 contains a groove 14 for the abrading member 4, which is further positioned by resting against pins 9, 10 projecting from the part 1 through the channel member. A funnel-form inlet for the fluid binder is formed by semi-conical grooves 22 in the two parts. Channels 16, 17 for the circulation of cooling water are provided. Fig. 6 shows the casting machine, the two parts of the mould being mounted in a frame formed of end members 31, 34 connected by bars 32, 33. The part 1 of the mould is supported from the end member 31, and the part 2 from an intermediate member or yoke 40. The mould is closed by sliding the yoke 40 towards the member 31 by operating a handle 42 connected to the yoke by a link 41, a spring 49 maintaining the closure. The frame carrying the mould is then swung rearwardly about pivots 29 by rotating a shaft 53 carrying a drum with a helical cam groove in which engages the end of a lever 50 connected at the other end to the frame. This movement causes the inlet 22 of the mould to engage over the delivery nozzle of a cylinder containing the molten binding material. Further rotation of the shaft operates, through a cam 59 and lever 68, the piston of the cylinder to force the binder into the mould. The rotation of the shaft 53 is then reversed to restore the parts to their initial position, and the handle 42 is operated to open the mould. As the mould is opened pins 48 mounted on a cross-piece 47 carried by a rod 46 passing through the yoke 40 enter holes 15 (Fig. 5) in the mould and eject the article. To eject the article from the other part of the mould a pin 38 operated by a lever 39 and entering a hole 8 (Fig. 1) in the mould is provided.

Abstract: 951,796. Screening apparatus. F. F. DAUENHAUER. Dec. 19, 1960, No.43592/60. Heading B2H. A mixture of hops and dirt is caused to move down an inclined multi-slotted surface while being acted on by mechanical elements which protrude through and move in the slots, so that the dirt drops through the slots. An inclined frame comprises spaced rods 14 forming parallel slots 16 in a surface 13. The ends of the rods pass through cross members 17 and are held by cotter pins. Endless chains 21, 22 run along each side of the frame, driven in unison by sprockets on shafts 23, 33 which are so mounted that the upper runs of the chains are just beneath the inclined slotted surface 13, chain skids 43, 44 being fitted to prevent sagging. Combs 46 span the space between the chains, their teeth passing between the rods 14. The hops, with the dirt remaining from a previous separating stage, are fed by a conveyer 56 across a plate 57 and drop on the surface 13, on which they are confined by sloping side shields. At the discharge point the hops fall on a take-off conveyer 61, guided by a canvas drag strip 64. The dirt drops on a take-off conveyer 62, the separation being maintained by a divided strip 63. One arrangement, Fig. 7, uses a known separator in the form of a trommel 66 from which the hops and remaining dirt fall on two inclined, upwardly-moving screen conveyers 71, 76 and thence to a separator with a surface 13 according to the invention. The dirt which is conveyed round the tops of the screens 71, 76 falls on a barrier screen 73 which directs it to a take-off conveyer 74. Air is blown through the moving screens 71, 76 by a fan 77, part being diverted upwards by a deflector 79 towards the conveyer 71 to blow dirt over the top.
