Title: Improvements in moulding by sand-blowing
IPC: B22C15/24
Filed: 1935-05-31
Abstract: 437,509. Moulding-machines. BILLAND, C., 152, Pirmasenserstrasse, Kaiserslautern, Rheinpflaz, Germany. May 31, 1935, Nos. 15891 and 15892. Convention dates, May 31, 1934 and March 13, 1935. [Class 83 (i)] Core-making.-In packing sand into mould- or core-boxes by air blast the nozzle is progressively withdrawn during the process. This movement may be produced by reaction of the blast and may move the box 1 or the nozzle 3 with its sand container 4 or both, the movement being regulated by counterbalance weights 11 some of which may be lifted off by projections, during the movement, to reduce the speed. In modifications the speed may be regulated by the nozzle picking up weights as it moves or by a braking device. A fluid-pressure cylinder may be used to initiate or control the movement. If the device is arranged horizontally no counterbalance is required and the movement is regulated by a valve 15, Fig. 6, on a pneumatic cylinder 13 the piston of which is connected to the nozzle. This may be guided by projections or rollers engaging the walls of the box 1 or a pin 27 which forms a vent hole in the core &c. Two nozzles may be used simultaneously or successively at opposite ends of a core-box as shown, a temporary or permanent partition being employed in the box if desired. If simultaneously, they may be interconnected to ensure equal and opposite movement. After withdrawal of the nozzles the box may be moved laterally by a cylinder C, Fig. 5, and automatically opened by a link 20. The nozzle may be shaped as shown in Figs. 9 or 11 to allow the introduction of a core-iron 28 or 30, previously treated with lime water if desired, partitions 3<a> connecting the inner and outer tubes being shaped, if desired, to give a spiral motion to the blast. For other shapes of box the nozzles may move along curved paths. A tubular mould or core may be formed by using an annular nozzle comprising inner and outer walls c<2>, c<1>, Fig. 13. In a modification the wall c<2> is dispensed with, the upper end D being closed in or made a sliding fit on an extension of the core b. In other modifications the inner or outer wall is extended as at C<1>1, Fig. 16, to act, instead of the core b or box a, in moulding the sand. In another modification two annular nozzles, which may be supplied with different kinds, of sand, are formed by inserting a wall c<3>, Fig. 18, which extends beyond the walls c<1>, c<2> and thus forms a mould M and core R simultaneously. The pins 27 are for forming vent holes H. To avoid the risk of the wall c<3> sticking to the moulded sand the nozzle may be given a spiral movement the pins 27 being curved to correspond or being replaced by leather &c. The compactness of the sand may be varied by varying the air pressure or the distance of the nozzle. A number of nozzles may be employed and the box may be of any desired shape.

Title: Sheet feeding apparatus
IPC: G03B27/52
Filed: 1963-04-16
Abstract: 1,046,785. Feeding sheets. PLASTIC COATING CORPORATION. April 16, 1963 [April 24, 1962], No. 15899/65. Divided out of 1,046,781. Heading B6B. [Also in Division G2] A sheet feeding mechanism applied to an electrophotographic copying apparatus (see Division G2) has a sheet supply magazine formed by a plate 34 and guides 35, 36, 37, and 38. The plate 34 may be withdrawn in the manner of a drawer, Fig. 5 (not shown), for replenishment of the stack on the plate 34. The plate 34 is raised, such that the uppermost sheet of the stack, not shown, contacts the underside of a hollow platen 30. An air cylinder 20 has a piston-rod 21 which actuates an arm 15 connected to its other arms 13, 14 and an arm 16, Fig. 2 (not shown), each arm carrying a roller 19 engaging the underside of plate 34, Fig. 1. The cylinder 20 is supplied with air under pressure by a pump 25 which withdraws air through orifices in the underside of platen 30. Should the supply of sheets on the plate 34 be exhausted and the platen does not receive a copy sheet a pressure sensitive switch 31 is left in open position, thus preventing movement of the platen 30. The passage of air into the orifices in the underside of the platen 30 creates an audible whistling sound which warns the operator. The plate 34 returns under its own weight when air pressure in the cylinder 20 is released by a solenoid valve 26. A limit switch 45 actuated by the return of plate 34 initiates the operation of the platen 30 to position a copy sheet, held thereon by suction, in an optical plane for exposure to an image, to position the sheet for pick-up by a conveyer (not shown), and to return to initial position. The platen 30 is reciprocated between plates 72, 73, Fig. 3, by a pawl 63 on a chain 86 driven by a shaft 81. The pawl 63 engages a slot 64 in a plate 54. The shaft 81 is driven by a motor 76 through a speed reducer 77. A gear sector 55 secured to the platen 30 engages a rack 74, causing the platen 30 to tilt through 90 degrees to place the copy sheet in the image plane (broken line position) for exposure. The platen is laterally displaced on its return stroke against the action of spring 56 through the co-operation of a shift arm 93 and roller 97, such that the exposed copy sheet is grasped by a gripper (not shown).

Title: Improved method and apparatus for drying or smoking fish
IPC: A23B4/052
Filed: 1920-06-12
Abstract: 165,650. F÷rland, T. R. June 12, 1920. Preserving fish.-In apparatus for smoking and drying fish in which the fish are carried on a conveyer through a smoking and drying chamber the chamber is divided into a number of superposed compartments, each with its conveyer, from one to another of which the fish pass. The fish pass from a hopper A to an elevator B, a spring plate C preventing them from falling between the hopper and the elevator. The elevator delivers them by way of a rotary drum D, formed with an open periphery and radial partitions, to the drying and smoking chamber which is divided by horizontal partitions F<1> - - F<4> into compartments containing conveyer belts E of wire cloth or the like, of such mesh that the scales can pass freely through them. The fish pass from belt to belt through openings at alternate ends of the partitions F' - - F<4> and are delivered by a drum D<2> to a conveyer belt N. Smoke and hot air can be introduced at either end of the drying-chamber, and the smoke can be passed over electric heating elements on its way to the chamber. Electric heaters may also be disposed in the chamber-

Filed: 1968-04-03
Abstract: 1,214,668. Welding by pressure. CATERPILLER TRACTOR CO. 3 April, 1968 [21 April, 1967], No. 16016/68. Heading B3R. In a method of inertial friction welding a workpiece of tungsten carbide in a metal matrix to a workpiece of carbon or alloy steel the relative velocity of the workpieces at the outer diameter of the interface, input energy and axial pressure are controlled to provide an energy transfer rate which produces a discernible layer of intermediate compound which acts as a bond between the workpieces. The steel workpiece WP1 is clamped in a rotatable chuck 26 on a spindle 22 and the workpiece of tungsten carbide material WP2 is clamped in a non- rotatable chuck 28 on a tailstock 30 which is movable towards the chuck 26 by a ram 32. The workpiece WP1 and a flywheel 24 on the spindle 22 are driven by the motor 12 until a predetermined velocity is reached, the motor is shut off and the ram 32 operates to bring the workpieces into contact. When the weld temperature is reached a constant or increasing upsetting pressure is applied by the ram and the spindle 22 comes to rest as the flywheel energy is expended and the weld is completed. In examples tungsten carbide in a cobalt matrix is welded to carbon steel and tungsten carbide in a nickel matrix and tungsten carbide in a cobalt matrix are welded to alloy steel with a relative velocity of 400-1150 feet per min.; an axial pressure of 15,000-22,500 lbs per square inch and input energy of 42,500-51,000 feet lbs per square inch. In a 500 times photomicrograph the intermediate compound material is clearly visible.
